         (ii)    Each Acquisition Lender is hereby authorized to record the
date and the amount of each Acquisition Loan Advance made by it and the Type
thereof and the date and amount of each payment and prepayment of principal
made with respect thereto, and all Conversions of such Advances pursuant to
Section 2.04, and prior to any Transfer of its Acquisition Loan Note, may
annotate on the schedule forming a part thereof appropriate notations to
evidence the foregoing information with respect to each such Acquisition Loan
Advance then outstanding; provided, that, failure by such Acquisition Lender to
make any such annotation or any error therein shall not affect the obligations
of the Borrower hereunder or under such Acquisition Loan Note in respect of
such Acquisition Loan Advances evidenced thereby.  Each Acquisition Lender is
hereby irrevocably authorized by the Borrower to endorse its Acquisition Loan
Note and to attach to and make a part of its Acquisition Loan Note a
continuation of such schedule as and when required.

                 (c)      Type of Acquisition Loan Advances.  All or any
portion of Acquisition Loan Advances shall be either Base Rate Advances or LIBO
Rate Advances and may be Converted or continued from time to time pursuant to
Section 2.04.

                 (d)      Use of Proceeds of Acquisition Loans.  The Borrower
shall use (or cause to be used by its Subsidiaries) the proceeds of each
Acquisition Loan solely to pay Acquisition Costs as contemplated by this
Agreement.  No proceeds of any Acquisition Loan may be used to make a
contribution to the capital of any Subsidiary of the Borrower.

                 (e)      Repayment of Acquisition Loans.  The Borrower shall
repay all Acquisition Loans in full on the Final Maturity Date.

                 Section 2.02     Working Capital Loans.

                 (a)      Working Capital Loan Commitments.  (i) Subject to the
terms and conditions of this Agreement and relying on the representations and
warranties set forth herein, each Working Capital Lender severally agrees to
make Working Capital Advances to the Borrower, during the Working Capital Loan
Availability Period on any Working Capital Loan Funding Date, in an amount
equal to its Pro Rata Share of the Working Capital Loan requested to be made on
such date, but in no event shall the sum of (x) any Working Capital Advance
made by any Working Capital Lender as of any date, plus (y) the aggregate
principal amount of Working Capital Advances previously made by such Working
Capital Lender that remain outstanding and unpaid as of such date, plus (z)
such Working Capital Lender's ConEd Letter of Credit Exposure on such date,
exceed such Working Capital Lender's Working Capital Loan Commitment.  As of
any date, the aggregate amount of all Working Capital Advances made by all
Working Capital Lenders hereunder and that remain outstanding and unpaid from
time to time plus the aggregate amount of all ConEd Letter of Credit Exposure
on such date, shall not in any event exceed the Working Capital Loan Available
Amount as of such date.  Unless earlier terminated in accordance herewith, the
Working Capital Loan Commitments shall terminate in their entirety on the Final
Maturity Date.  Subject to the terms hereof, Working Capital Loans that are
repaid prior to the Final Maturity Date may be reborrowed.

         (ii)    The failure of any Working Capital Lender to make a Working
Capital Advance to be made by it as part of any Working Capital Loan shall not
relieve, in and of itself, any other

                                       34
<PAGE>   42
Working Capital Lender of its obligation hereunder to make its Working Capital
Advance on the date of such Working Capital Loan, but no Working Capital Lender
shall be responsible for the failure of any other Working Capital Lender to
make the Working Capital Advance to be made by such other Working Capital
Lender on the date of such Working Capital Loan.

                 (b)      Working Capital Loan Notes.  (i) All Working Capital
Advances made by each Working Capital Lender shall be evidenced by a Working
Capital Loan Note of the Borrower in the form of Exhibit B hereto (each a
"Working Capital Loan Note" and, collectively, the "Working Capital Loan
Notes"), dated the Closing Date, payable to such Lender for the account of its
Applicable Lending Office in an aggregate principal amount equal to its Pro
Rata Share of the Maximum Working Capital Loan Amount and otherwise duly
completed.  Each Working Capital Loan Note shall (A) represent the Borrower's
obligation to pay the aggregate unpaid principal amount of all outstanding
Working Capital Advances made by such Lender, (B) be stated to mature on the
Final Maturity Date, (C) bear interest for the period from the date thereof
until paid in full on the unpaid principal amount thereof from time to time
outstanding at the applicable interest rate per annum provided in, and payable
as specified in, this Agreement, and (D) be entitled to the benefits of this
Agreement, the Security Documents and the Subsidiary Guarantees.

         (ii)    Each Working Capital Lender is hereby authorized to record the
date and amount of each Working Capital Advance made by it and the Type thereof
and the date and amount of each payment and prepayment of principal made with
respect thereto, and all Conversions of such Advances pursuant to Section 2.04,
and prior to any Transfer of its Working Capital Loan Note may annotate on the
schedule forming a part thereof appropriate notations to evidence the foregoing
information with respect to each such Working Capital Advance then outstanding;
provided, that, failure by such Working Capital Lender to make any such
annotation or any error therein shall not affect the obligations of the
Borrower hereunder or under such Working Capital Loan Note in respect of such
Working Capital Advances evidenced thereby.  Each Working Capital Lender is
hereby irrevocably authorized by the Borrower to endorse its Working Capital
Loan Note and to attach to and make a part of its Working Capital Loan Note a
continuation of such schedule as and when required.

                 (c)      Types of Working Capital Advances.  All or any
portion of any Working Capital Advances shall be either Base Rate Advances or
LIBO Rate Advances, and may be Converted or continued from time to time
pursuant to Section 2.04.

                 (d)      Use of Proceeds of Working Capital Loans.  The
Borrower shall use the proceeds of each Working Capital Loan solely to pay (i)
Operating Costs contemplated by the then current Operating Budget and (ii) the
Borrower's allocated pro rata share of prepaid real property taxes payable in
respect of the Portfolio Assets in each case, to the extent that funds in the
Operating Account are insufficient for any such purpose.  In no event shall the
proceeds of Working Capital Loans be used to (i) pay Acquisition Costs
(excluding prepaid real property taxes of the nature referenced above), (ii)
pay Debt Service, (iii) make Distributions, or (iv) make a contribution to the
capital of any Subsidiary of the Borrower.

                 (e)      Repayment.  (i) The Borrower shall repay the
principal of all outstanding Working Capital Loans in full on the Final
Maturity Date.

<PAGE>   43
         (ii)    Notwithstanding anything to the contrary in this Agreement,
for so long as the Working Capital Loan Commitments are in effect, the Borrower
agrees to repay the entire principal amount of Working Capital Loans
outstanding from time to time such that (A) on each Semi-Annual Date occurring
prior to the Final Maturity Date on which all conditions precedent for making a
Distribution in accordance with the terms of the Deposit Account Agreement and
the other Financing Documents have been satisfied, the Borrower shall prepay
all Working Capital Loans outstanding under this Agreement other than Working
Capital Loans not in excess of $10,000,000 in the aggregate the proceeds of
which have been used to prepay real property taxes in respect of any of the
Portfolio Assets, and (B) in all events, for a period of thirty (30)
consecutive days during each calendar year in which either an Acquisition Loan
Commitment or a Working Capital Loan Commitment is in effect or any Loan
remains outstanding and unpaid, there shall be no Working Capital Loans
outstanding under this Agreement.

                 Section 2.03     Borrowings.

                 (a)      Acquisition Loans.  Each Acquisition Loan shall be
made on notice from the Borrower to the Administrative Agent, given not later
than 10:00 a.m. (New York City time) (x) on the third (3rd) Business Day prior
to the proposed Acquisition Loan Funding Date, if such Acquisition Loan is to
be a LIBO Rate Loan, or (y) on the Business Day prior to the proposed
Acquisition Loan Funding Date, if such Acquisition Loan is to be a Base Rate
Loan.  Such notice by the Borrower (a "Notice of Acquisition Borrowing") shall
be irrevocable and shall be in writing in substantially the form of Exhibit C,
specifying therein (i) the proposed Acquisition Loan Funding Date, (ii) the
aggregate amount of the Acquisition Loan to be made on such date, (iii) the
requested Type of Acquisition Loan, (iv) the specific Acquisition Costs to be
paid with the proceeds of such Acquisition Loan, and (v) with respect to a LIBO
Rate Loan, the requested Interest Period for such Acquisition Loan.  The
Administrative Agent shall give to each Acquisition Lender prompt notice of the
Notice of Acquisition Borrowing by telecopy, telex or cable.  Each Acquisition
Lender shall, before 10:00 a.m.  (New York City time) on the applicable
Acquisition Loan Funding Date, make available to the Administrative Agent, for
the account of its Applicable Lending Office, in immediately available funds,
the amount of such Acquisition Lender's Acquisition Loan Advance.  Subject to
the Administrative Agent's receipt of such funds and fulfillment of the
applicable conditions set forth in Article III for such Acquisition Loans, the
Administrative Agent will make such funds available to the Borrower at its
account with the Administrative Agent at its Applicable Lending Office or at
such other account designated by the Borrower in the Notice of Acquisition
Borrowing.

                 (b)      Working Capital Loans.  Each Working Capital Loan
shall be made on notice from the Borrower to the Administrative Agent, given
not later than 10:00 a.m. (New York City time) (x) on the third (3rd) Business
Day prior to the proposed Working Capital Loan Funding Date, if such Working
Capital Loan is to be a LIBO Rate Loan, or (y) on the Business Day prior to the
proposed Working Capital Loan Funding Date, if such Working Capital Loan is to
be a Base Rate Loan. Such notice by the Borrower (a "Notice of Working Capital
Borrowing"), shall be irrevocable and shall be in writing in substantially the
form of Exhibit D, specifying therein (i) the proposed Working Capital Loan
Funding Date, (ii) the requested aggregate amount of the Working Capital Loan,
(iii) any specific payment instructions regarding the disbursement of the
proceeds of such Working Capital Loan, (iv) the requested Type of

                                       36
<PAGE>   44
Working Capital Loan and (v) with respect to a LIBO Rate Loan, the initial
Interest Period applicable thereto.  The Notice of Working Capital Borrowing
shall be accompanied by the certificates and information required by Section
3.03.  The Administrative Agent shall give each Working Capital Lender prompt
notice of the Notice of Working Capital Borrowing by telecopy, telex or cable.
Each Working Capital Lender shall, no later than 10:00 a.m. (New York City
time) on the applicable Working Capital Loan Funding Date, make available to
the Administrative Agent, for the account of its Applicable Lending Office, in
immediately available funds, the amount of such Working Capital Lender's
Working Capital Advance.  Subject to the Administrative Agent's receipt of such
funds and fulfillment of the applicable conditions set forth in Article III for
such Loans, the Administrative Agent will make such funds available to the
Borrower by depositing the proceeds of such Working Capital Loan into the
Operating Account.

                 (c)      Participations.  If the Administrative Agent has not
received from the Borrower the payment required by Section 2.16(g) by 12:30
p.m. (New York City time), on the Business Day immediately following the date
on which the Issuing Bank has notified the Borrower and the Administrative
Agent that payment of a draft presented under the ConEd Letter of Credit will
be made, as provided in Section 2.16(g), the Administrative Agent will promptly
notify the Issuing Bank and each Working Capital Lender of the ConEd Letter of
Credit Disbursement and, in the case of each Working Capital Lender, its Pro
Rata Share (based on such Working Capital Lender's Working Capital Loan
Commitment) of the ConEd Letter of Credit Disbursement. Not later than 10:00
a.m. (New York City time) on the next Business Day, each Working Capital Lender
shall, irrespective of the existence of any Default or Event of Default or
failure of any other applicable condition precedent, make available its Pro
Rata Share of the ConEd Letter of Credit Disbursement, in Federal or other
funds immediately available in New York, New York, to the Administrative Agent
at its address set forth in Section 9.01.  Any such funding of a ConEd Letter
of Credit Disbursement by the Working Capital Lenders shall be considered as
Working Capital Advances made to the Borrower.  Any Working Capital Loans made
pursuant to this Section 2.03(c) shall be made as Base Rate Loans and the
Administrative Agent will promptly make such funds available to the Issuing
Bank.

                 Section 2.04     Election of Interest Rates.

                 (a)      So long as no Default or Event of Default shall have
occurred and be continuing (and notwithstanding the existence of any Default or
Event of Default with respect to a Conversion from a LIBO Rate Loan to a Base
Rate Loan), the Borrower may from time to time elect to Convert any Loan of any
Type to a Loan of the same or any other Type on the following terms and subject
to the following conditions:

                          (i)     Each such Conversion shall be made as to all
                 or a portion of the outstanding Loans, on notice given not
                 later than 10:00 a.m.  (New York City time) on the third (3rd)
                 Business Day prior to the date of the proposed Conversion, in
                 the case of any such Conversion into LIBO Rate Loans, or on
                 the Business Day prior to the date of the proposed Conversion,
                 in the case of any such Conversion into Base Rate Loans, by
                 the Borrower to the Administrative Agent, who shall give each
                 applicable Lender prompt notice thereof.  Each such notice of
                 Conversion (a "Notice of Conversion") shall be in writing in
                 substantially the form of Exhibit E hereto, specifying therein
                 the requested (A) date of such

                                       37
<PAGE>   45
                 Conversion, (B) Type of, and, with respect to LIBO Rate Loans,
                 Interest Period applicable to, the Loans proposed to be
                 Converted, (C) Type of Loans to which such Loans are proposed
                 to be Converted, (D) in the case of a Conversion to LIBO Rate
                 Loans, initial Interest Period to be applicable to the Loans
                 resulting from such Conversion and (E) aggregate amount of
                 Loans proposed to be Converted.  If the Notice of Conversion
                 applies only to a portion of the aggregate principal amount of
                 the Loans, (X) such portion shall be allocated ratably among
                 the applicable Lenders and (Y) both the portion to which the
                 Notice of Conversion applies and the remaining portion to
                 which it does not apply, shall be sufficient to meet the
                 minimum amounts specified in Section 2.06(f).  In the case of
                 a proposed Conversion into LIBO Rate Loans, the Administrative
                 Agent shall, within one Business Day of receiving the Notice
                 of Conversion from the Borrower, notify each applicable Lender
                 of the interest rate to be applicable to such Lender resulting
                 from such Conversion pursuant to this Section 2.04.

                          (ii)    LIBO Rate Loans may not be Converted on a
                 date other than the last day of the Interest Period then
                 applicable thereto.

                          (iii)   No Conversion may be requested by the
                 Borrower hereunder unless made in compliance with the
                 definition of "Interest Period," Section 2.06 and Section
                 2.10.

                          (iv)Any selection by the Borrower of a longer or
                 shorter Interest Period to be applicable to any LIBO Rate Loan
                 shall be deemed a Conversion pursuant to this Section 2.04,
                 shall be governed by the terms and conditions hereof and shall
                 be notified to the Administrative Agent as herein provided. In
                 the event the Borrower shall fail to elect an Interest Period
                 in respect of any LIBO Rate Loan prior to the expiration of
                 the then current Interest Period in respect of such LIBO Rate
                 Loan, then such LIBO Rate Loan shall automatically be
                 Converted into a Base Rate Loan in accordance with this
                 Section 2.04.

                 (b)      Each Notice of Borrowing and Notice of Conversion
shall be irrevocable and binding on the Borrower.  The Borrower shall indemnify
each Lender against any loss, cost or expense incurred by such Lender as a
result of any failure to fulfill, on or before the proposed date specified in
such Notice of Borrowing or Notice of Conversion, as the case may be, the
applicable conditions set forth in this Article II or Article III, including,
without limitation, any loss, cost or expense incurred by reason of the
liquidation or re-employment of deposits or other funds acquired by such Lender
to fund or Convert such Loan.

                 (c)      So long as any Interest Hedge Contract is in effect
with respect to any Loans, the Borrower shall maintain as LIBO Rate Loans
having Interest Periods corresponding to the payment dates under such Interest
Hedge Contract an aggregate amount of Loans at least equal to the notional
amount then in effect under such Interest Hedge Contract, except to the extent
the Borrower would be prevented from complying with this Section 2.04(c) by
operation of Section 2.10.

                 Section 2.05     Fees.

<PAGE>   46
                 (a)      Commitment Fee.  The Borrower shall pay to the
Administrative Agent, quarterly in arrears on each Quarterly Payment Date, for
the account of each Lender, commitment fees (the "Commitment Fees") of (i)
0.375% per annum on the average daily unutilized amount of each Acquisition
Lender's Acquisition Loan Commitment during the period from the Closing Date
until, and including, the termination of all Acquisition Loan Commitments
pursuant to the terms of this Agreement, and (ii) 0.375% per annum on the
average daily unutilized amount of each Working Capital Lender's Working
Capital Loan Commitment during the period from the Closing Date until, and
including, the Final Maturity Date.  For purposes of this Section 2.05(a), the
"unutilized amount" of a Working Capital Lender's Working Capital Loan
Commitment on any date shall mean the amount of such Working Capital Lender's
Working Capital Loan Commitment on such date, minus the sum of (X) its
outstanding Working Capital Advances on such date and (Y) its ConEd Letter of
Credit Exposure on such date.

                 (b)      Agency Fee.  The Borrower shall pay the Agency Fee to
the Administrative Agent, for the Administrative Agent's own account, in
accordance with the terms of the Administrative Agent Fee Side Letter.

                 (c)      ConEd Letter of Credit Fees.  The Borrower shall pay
the ConEd Letter of Credit Fees to the applicable Persons in accordance with
the terms set forth in Section 2.16 below.

                 (d)      Other Fees.  The Borrower shall pay all Fees not
specifically contemplated by clauses (a) and (b) of this Section 2.05 to the
appropriate Persons in the amounts and at such times as set forth in the Fee
Side Letters.

                 Section 2.06     Interest.  The Borrower shall pay interest
on the unpaid principal amount of each Advance made by each Lender from the
date of such Advance until such principal amount shall be paid in full, at one
of the following rates per annum:

                 (a)      If such Advance is a Base Rate Advance, a rate per
annum equal at all times to the sum of the Base Rate in effect from time to
time plus the Applicable Margin, payable quarterly in arrears on each
applicable Interest Payment Date and on the date that such Base Rate Advance
shall be repaid in full.

                 (b)      If such Advance is a LIBO Rate Advance, a rate per
annum equal at all times during each Interest Period for such Advance to the
sum of the LIBO Rate for such Interest Period for such Advance plus the
Applicable Margin, payable on the applicable Interest Payment Date and on the
date that such LIBO Rate Advance shall be repaid in full.

                 (c)      If an Event of Default shall have occurred and be
continuing and whether or not so specified in any Note, the Borrower shall pay,
upon receipt of written demand, interest on the entire principal amount of the
Loans to the extent permitted by applicable Requirements of Law, on any overdue
installment of interest and on any other amount due hereunder during such
period at a rate per annum equal at all times to 2.00% plus the LIBO Rate for
such period plus the LIBO Rate Margin for such period, if the Loans are LIBO
Rate Loans or, at a rate per

                                       39
<PAGE>   47
annum equal to 2.00% plus the Base Rate for such period plus the Base Rate
Margin for such period, if the Loans are Base Rate Loans, which increased
interest shall be payable on the last Business Day of each month during the
continuation of such Event of Default.

                 (d)      If the Administrative Agent is unable at any time to
determine the LIBO Rate for LIBO Rate Loans, the right to maintain the Loans as
LIBO Rate Loans shall be suspended at the end of the then current Interest
Period and all Loans shall be maintained as Base Rate Loans until the
Administrative Agent shall notify the Borrower and the Lenders that the
circumstances causing such suspension no longer exist.

                 (e)      At no time shall more than six (6) different Interest
Periods be in effect as to outstanding LIBO Rate Loans hereunder.

                 (f)      Each LIBO Rate Loan shall be in a minimum aggregate
principal amount of $1,000,000.

                 Section 2.07     Mandatory Prepayments.

                 (a)      All Extraordinary Proceeds received by the
Administrative Agent or any Borrower Entity shall be applied to prepay the then
outstanding Acquisition Loans in accordance with the Deposit Account Agreement,
and after all Acquisition Loans have been prepaid in full, applied to prepay
then outstanding Working Capital Loans in accordance with the Deposit Account
Agreement.  Any prepayment of Working Capital Loans required by this Section
2.07(a) shall automatically reduce pro rata the amount of Working Capital Loan
Commitments by an amount equal to the prepayment so required. Contemporaneously
with any reduction of Working Capital Commitments required by this Section
2.07(a), then the Borrower shall cash collateralize with the Administrative
Agent the difference between (y) any ConEd Letter of Credit Exposure existing
at such time, less (z) the aggregate amount of the Working Capital Loan
Commitments existing after the application of the terms of this Section
2.07(a), until such time as such ConEd Letter of Credit Exposure no longer
exists.  Nothing in this Section 2.07(a) shall be deemed to imply that any of
the activities or actions described in clauses (ii) or (iii) of the definition
of Extraordinary Proceeds are permitted under this Agreement other than as
specifically set forth in this Agreement.

                 (b)      In addition to the foregoing, until the Final
Maturity Date, the Borrower shall prepay the Acquisition Loans, promptly after
each Semi-Annual Date to the extent of Excess Cash Flow as determined as of
each such Semi-Annual Date in the percentage listed below, based on the
applicable Debt Service Coverage Ratio calculated on a trailing 12-month basis:

<PAGE>   48
                 Notwithstanding the foregoing, after the Maximum Permitted
Distribution Amount shall have been deposited in the Distribution Account and
distributed therefrom at the direction of the Borrower, 100% of Excess Cash
Flow shall be applied to the prepayment of the Acquisition Loans on each
Quarterly Payment Date irrespective of the Debt Service Coverage Ratio as of
such date.

                 In the case of LIBO Rate Loans which shall be prepaid pursuant
to this Section 2.07, the Borrower shall, concurrently with such prepayment,
pay all applicable Funding Breakage Costs in accordance with Section 2.09(c)
below.

                 In the event the interest rate on any Acquisition Loans is
fixed or capped pursuant to an Interest Hedge Contract, the Borrower shall pay
all Settlement Amounts required under such Interest Hedge Contract in
connection with any mandatory prepayment of such Loan.

                 Section 2.08     Voluntary Prepayment; Termination of
Commitments; Working Capital Commitment Reductions.  (a) The Borrower may, upon
at least five Business Days' prior written notice to the Administrative Agent
stating the proposed date and aggregate principal amount of the prepayment, and
if such notice is given the Borrower shall, prepay the outstanding principal
amounts of the Loans in whole or ratably in part in the amount set forth in
such notice, together with accrued interest to the date of such prepayment on
the principal amount prepaid; provided, that (i) each partial prepayment shall
be in a minimum aggregate principal amount of $1,000,000 or whole multiples
thereof (or, if less, the entire balance then remaining), (ii) concurrently
with such payment, the Borrower shall pay all applicable Funding Breakage Costs
in accordance with Section 2.09(c) below and, (iii) to the extent applicable,
the Borrower shall have reduced the aggregate notional amounts of any Interest
Hedge Contracts existing on such prepayment date such that such aggregate
notional amounts do not exceed the aggregate principal amount of outstanding
Loans on such date and shall have paid any Settlement Amounts incurred in
connection therewith.  Each such voluntary prepayment shall otherwise be
without penalty or premium.

                 (b)      The Acquisition Loan Commitments shall be
automatically terminated on the expiration of the Acquisition Loan Availability
Period.  The Working Capital Loan Commitments shall be automatically terminated
on the expiration of the Working Capital Loan Availability Period.

                 (c)      Upon at least five Business Days' prior irrevocable
written or telecopy notice to the Administrative Agent, the Borrower may at any
time in whole permanently terminate, or from time to time in part permanently
reduce, the Working Capital Loan Commitments; provided, that, (i) each partial
reduction of the Working Capital Loan Commitments shall be in an aggregate
principal amount which is equal to $1,000,000 or an integral multiple thereof;
(ii) concurrently with such payment, the Borrower shall pay all applicable
Funding Breakage Costs in accordance with Section 2.09 (c) below, (iii) to the
extent applicable, the Borrower shall have reduced the aggregate notional
amounts of any Interest Hedge Contracts existing on such prepayment date such
that such aggregate notional amounts do not exceed the aggregate principal
amount of outstanding Loans on such date and shall have paid any Settlement
Amounts incurred in connection therewith, and (iv) concurrently with any such
reduction in the Working Capital Loan Commitments, the Borrower shall deposit
with the

                                       41
<PAGE>   49
Administrative Agent cash collateral in an amount equal to the difference
between (y) any ConEd Letter of Credit Exposure existing at such time, less (z)
the aggregate amount of the Working Capital Loan Commitments existing after the
effectiveness of such reduction, until such time as such ConEd Letter of Credit
Exposure no longer exists.

                 (d)      Each reduction in the Working Capital Loan
Commitments shall be made ratably among the Working Capital Lenders in
accordance with their respective Working Capital Loan Commitments.  The
Borrower shall pay to the Administrative Agent for the account of the Working
Capital Lenders, on the date of each termination or reduction of the Working
Capital Loan Commitments, all accrued but unpaid Commitment Fees on the amount
of the Working Capital Loan Commitments so terminated or reduced accrued to the
date of such termination or reduction.

                 Section 2.09     Increased Costs; Capital Adequacy; Funding
Breakage Costs.

                 (a)      If, due to either (i) the enactment, promulgation or
any change (including any change by way of imposition of reserve requirements
in the case of LIBO Rate Loans) in any Requirement of Law or in the
interpretation or administration of any Requirement of Law by any Governmental
Authority charged with the interpretation or administration thereof on or after
the date hereof or (ii) the compliance with any guideline or request from any
such Governmental Authority (whether or not having the force of law) imposed on
or after the date hereof, there shall be any increase in the cost to any Lender
of agreeing to make or making, funding or maintaining LIBO Rate Loans, then
such Lender shall deliver to the Borrower and the Administrative Agent a
certificate as to the amount of such increased cost setting forth in reasonable
detail the basis for calculation thereof as soon as practicable but in no event
later than one hundred twenty (120) days after such Lender has actual knowledge
of the event (the date that is 120 days from the date any Lender obtains actual
knowledge of any such event being referred to herein as the "Notice Date").
Within fifteen (15) days after delivery of such certificate, the Borrower shall
pay to such Lender the amount shown as due on the certificate; provided, that
the Borrower shall not be obligated to compensate that Lender for the amount of
such increased cost incurred during the period of time from the Notice Date to
the date of actual delivery of the certificate.  A certificate as to the amount
of such increased cost showing the basis therefor and the calculation thereof,
in reasonable detail, submitted to the Borrower and the Administrative Agent by
such Lender, shall be conclusive and binding for all purposes, absent manifest
error.

                 (b)      If any Lender determines that compliance with any
Requirement of Law or regulation or with any guideline or request from any
central bank or other governmental authority (whether or not having the force
of law) has the effect of reducing the rate of return on the capital of such
Lender or any corporation controlling such Lender as a consequence of, or with
reference to, this Agreement, the ConEd Letter of Credit or such Lender's
Commitments, or its making or maintaining Loans below the rate which the Lender
or any other corporation would have achieved but for such compliance (taking
into account the policies of such Lender or corporation with regard to
capital), then such Lender shall deliver to the Borrower and the Administrative
Agent a certificate setting forth in reasonable detail the amount being charged
by such Lender and the basis for the determination of such amount as soon as
practicable but in no event later than one hundred twenty (120) days after the
Notice Date in respect thereof.  Within fifteen (15) days after delivery of
such certificate, the Borrower shall pay to such Lender the

                                       42
<PAGE>   50
amount shown as due on the certificate; provided, that the Borrower shall not
be obligated to compensate that Lender for the amount of such charge incurred
with respect to a period of time from the Notice Date to the date of actual
delivery of the certificate.  A certificate as to such amounts, submitted to
the Borrower and the Administrative Agent by such Lender, shall be conclusive
and binding for all purposes, absent manifest error.

                 (c)      If any payment of principal of any LIBO Rate Loan is
made other than on the last day of the Interest Period for such Loan, as a
result of a payment or prepayment of such Loan or acceleration of the maturity
of the Notes or for any other reason, the Borrower shall, upon demand by any
Lender (with a copy of such demand to the Administrative Agent), pay to the
Administrative Agent for the account of such Lender any amounts required to
compensate such Lender for any additional losses, costs or expenses which it
may reasonably incur as a result of such payment, including, without
limitation, any loss, cost or expense incurred by reason of the liquidation or
reemployment of deposits or other funds acquired by any Lender to fund or
maintain such Loan.  The foregoing amounts payable by the Borrower under this
Section 2.09(c) shall be referred to herein as "Funding Breakage Costs".

                 (d)      Each Lender agrees to notify the Borrower and the
Administrative Agent of any circumstances that would cause the Borrower to pay
additional amounts pursuant to subsections (a) and (b) of this Section 2.09
within sixty (60) days of the date of such Lender's actual knowledge of such
circumstance and ability to calculate the additional amount payable by the
Borrower (the "Notice Date"); provided, that, the failure to give such notice
shall not affect the Borrower's obligation to pay any such additional amounts
accrued prior to the Notice Date or after delivery of such notice.

                 Section 2.10     Illegality.  If the enactment, promulgation
or any change in or in the interpretation of any Requirement of Law after the
Closing Date shall make it unlawful, or any central bank or other Governmental
Authority to which any Lender is subject shall assert that it is unlawful, for
any Lender or its LIBO Lending Office to perform its obligations hereunder to
make LIBO Rate Loans or to continue to fund or maintain LIBO Rate Loans
hereunder, then, on notice thereof and demand therefor by such Lender to the
Borrower through the Administrative Agent, the obligation of such Lender to
make or maintain LIBO Rate Loans shall be suspended until such Lender shall
notify the Administrative Agent that the circumstances causing such suspension
no longer exist and such Lender shall maintain all of its Loans as Base Rate
Loans.

                 Section 2.11     Payments and Computations.

                                       43
<PAGE>   51
                 (a)      The Borrower shall make each payment hereunder and
under the Notes not later than 12:00 Noon New York City time on the day when
due in Dollars to the Administrative Agent at its Applicable Lending Office in
immediately available funds.  The Administrative Agent shall promptly
thereafter cause to be distributed like funds relating to the payment of
principal, interest or Fees (other than amounts payable to the Administrative
Agent for Agency Fees and expenses or to reimburse the Administrative Agent
pursuant to Section 2.12) ratably to the Lenders for the account of their
respective Applicable Lending Offices, and like funds relating to the payment
of any other amount payable to any Lender to such Lender for the account of its
Applicable Lending Office, in each case to be distributed and applied in
accordance with the terms of subsection (b) of this Section 2.11.

                 (b)      All payments received by the Administrative Agent in
respect of the Loans whether received under Section 2.11(a), in connection with
any sale or other realization upon the Collateral or otherwise shall be
distributed and applied in the order and in the amounts set forth in the
Deposit Account Agreement.

                 (c)      The Borrower hereby authorizes each Lender, if and to
the extent that the Borrower has failed to pay amounts due hereunder or under
any Financing Document and as a result payment owed to such Lender is not made
when due hereunder or under any other Financing Document, to charge from time
to time against any or all of the Borrower's accounts with such Lender any
amount so due.  Each Lender receiving any payment as a result of charging any
such account shall promptly notify the Administrative Agent thereof and make
such arrangements as the Administrative Agent shall request to share the
benefit thereof in accordance with Section 2.13 and the Deposit Account
Agreement.

                 (d)      All computations of (i) interest hereunder based on
the LIBO Rate or the Federal Funds Rate and (ii) Commitment Fees, shall be made
by the Administrative Agent on the basis of a year of 360 days and all
computations of interest hereunder based on the Base Rate shall be made by the
Administrative Agent on the basis of a year of 365 or 366 days, as the case may
be, in each case for the actual number of days (including the first day but
excluding the last day) occurring in the period for which such interest or fees
are payable.  Each determination by the Administrative Agent of an interest
rate hereunder shall be conclusive and binding for all purposes, absent
manifest error.

                 (e)      Except as contemplated by the definition of "Interest
Period" for LIBO Rate Loans, whenever any payment hereunder or under any
Financing Document shall be stated to be due on a day other than a Business
Day, such payment shall be made on the first Business Day preceding such
required payment date.

                 (f)      Unless the Administrative Agent shall have received
notice from the Borrower prior to the date on which any payment is due to a
Secured Party hereunder that the Borrower will not make such payment in full,
the Administrative Agent may, but shall not be required to, assume that the
Borrower has made such payment in full to the Administrative Agent on such date
and the Administrative Agent may, in reliance upon such assumption, but shall
not be required to, cause to be distributed to each Secured Party on such due
date an amount equal to the amount then due such Secured Party.  If and to the
extent the Borrower shall not have so made such payment in full to the
Administrative Agent, each Lender shall repay to the

                                       44
<PAGE>   52
Administrative Agent forthwith on demand such amount distributed to such Lender
together with interest thereon, for each day from the date such amount is
distributed to such Lender until the date such Lender repays such amount to the
Administrative Agent, (i) at the Federal Funds Rate for the three Business Days
following demand by the Administrative Agent and (ii) the Federal Funds Rate
plus 1% for each day thereafter.

                 (g)      Unless the Administrative Agent shall have received
notice from a Secured Party prior to the date of any borrowing, or prior to the
time of any required payment by such Secured Party in respect of a ConEd Letter
of Credit Disbursement, that such Secured Party will not make available to the
Administrative Agent such Secured Party's portion of such borrowing or payment,
the Administrative Agent may assume that such Secured Party has made such
portion available to the Administrative Agent on the date of such borrowing or
payment in accordance with Section 2.03 and the Administrative Agent may, in
reliance upon such assumption, make available to the Borrower on such date a
corresponding amount.  If and to the extent that such Secured Party shall not
have made such portion available to the Administrative Agent, such Secured
Party and the Borrower severally agree to repay to the Administrative Agent
forthwith on demand such corresponding amount together with interest thereon,
for each day from the date such amount is made available to the Borrower or the
Issuing Bank (or, if the Administrative Agent and the Issuing Bank are the same
person, from the date of such payment in respect of a ConEd Letter of Credit
Disbursement), as applicable, until the date such amount is repaid to the
Administrative Agent at (i) in the case of the Borrower, the interest rate
applicable thereto pursuant to Section 2.06 or 2.16(g), as applicable, and (ii)
in the case of such Secured Party, (y) the Federal Funds Rate for the three
Business Days following demand by the Administrative Agent and (z) the Federal
Funds Rate plus 1% for each day thereafter.

                 Section 2.12     Taxes.

                 (a)      Any and all payments by the Borrower hereunder or
under the Notes to or for the benefit of any Secured Party shall be made free
and clear of and without deduction for any and all present or future taxes
(including, without limitation, income, gross receipts, franchise, sales, use,
personal property, license, stamp, documentary, recording, privilege or other
excise tax), levies, imposts, deductions, charges or withholdings, together
with any penalties, fines or interest thereon, and all liabilities with respect
thereto, imposed by any Governmental Authority, excluding, income or franchise
taxes measured by net income imposed under the laws of the United States or any
state, or any political subdivision thereof, in which each such Secured Party
is organized, or, solely in the case of each such Lender, in which the
Applicable Lending Office or the principal office of such Lender is located
(all such excluded net income taxes and franchise taxes hereinafter referred to
as "Income Taxes" and all nonexcluded taxes, levies, imposts, deductions,
charges, withholdings and liabilities being hereinafter referred to as
"Taxes").  If the Borrower shall be required by law to deduct any Taxes from or
in respect of any sum payable hereunder or under any Note to or for the benefit
of any Secured Party Lender, (i) the sum payable shall be increased as may be
necessary so that after making all required deductions of Taxes (including
deductions of Taxes applicable to additional sums payable under this Section
2.12) such Secured Party receives an amount equal to the sum it would have
received had no such deductions been made, (ii) the Borrower shall make such
deductions and (iii) the Borrower shall pay the full amount so deducted to the
relevant taxation authority or other authority in accordance with applicable
Requirement of Law.

                                       45
<PAGE>   53
                 (b)      In addition, without limiting the generality of this
Section 2.12, the Borrower agrees to pay any present or future stamp,
documentary, recording, privilege, intangible or similar taxes or any other
excise or property taxes, charges or similar levies that arise at any time or
from time to time (i) from any payment made under any and all Financing
Documents, (ii) from the transfer of the rights of any Secured Party under any
Financing Documents to any other Secured Party or (iii) from the execution or
delivery by the Borrower or any Credit Party of, or from the filing or
recording or maintenance of, or otherwise with respect to, any and all
Financing Documents.

                 (c)      The Borrower will indemnify each Secured Party for
the full amount of all Taxes excluding any Income Taxes imposed by any
jurisdiction on amounts payable under this Section 2.12) paid by, or imposed or
asserted against, such Secured Party or any Collateral, as the case may be, and
any liability (including penalties, interest and expenses) arising therefrom or
with respect thereto, which Taxes are imposed or asserted in any manner
resulting from or relating to or arising from the execution , delivery or
performance of the Financing Documents, the Transaction Documents or the
transactions contemplated thereby, whether or not such Taxes were correctly or
legally asserted by the relevant Governmental Authority.  A certificate as to
the amount of such payment or liability prepared by such Secured Party, absent
manifest error, shall be final, conclusive and binding for all purposes.
Payment of this indemnification shall be made within 30 days from the date such
Secured Party makes written demand therefor.  With respect to any such Taxes
for which any Secured Party is entitled to indemnification pursuant to this
paragraph, such Secured Party, agrees to cooperate with the Borrower and to
provide to it such information as may be reasonably requested by it for the
purpose of establishing the entitlement of the Borrower to a refund or credit
of all or any portion of such Taxes; provided, that, no Secured Party shall be
required to provide to the Borrower (a) copies of any of its tax or information
returns or (b) any other information which would prejudice the interests of
such Secured Party (as reasonably determined by such Secured Party, in its good
faith judgment) or which it reasonably deems to be of a confidential nature.

                 (d)      As soon as practicable after the date of any payment
of Taxes by the Borrower or other authority to the relevant Governmental
Authority, the Borrower will deliver to the Administrative Agent (for delivery
to each Lender) at its address referred to on its signature page hereto, the
original or a certified copy of a receipt issued by such Governmental Authority
evidencing payment thereof and identifying the Taxes paid.  If such receipt
does not identify such Taxes paid, and no procedure exists for identifying such
Taxes paid, the Borrower shall concurrently furnish to the Administrative Agent
a certificate, signed by a Responsible Officer of the Borrower providing such
identification.  The Borrower shall compensate each Secured Party, as the case
may be, for all reasonable losses and expenses sustained by such Secured Party,
as a result of any failure by the Borrower to so furnish such original or copy
of such receipt or such certificate.

                 (e)      If any Secured Party is not organized and existing
under the laws of the United States of America or any political subdivision
thereof or therein (a "Foreign Secured Party"), to the extent entitled to do so
under Applicable Law, such Secured Party shall furnish to the Borrower, on the
Closing Date (or on the date on which such Foreign Secured Party first becomes
a Secured Party pursuant to Section 9.06) a duly executed certificate to the
effect that such Foreign Secured Party is entitled to receive all amounts
payable under the Financing

                                       46
<PAGE>   54
Documents without deduction or withholding (or at a reduced rate of deduction
or withholding) on account of Taxes imposed by the United States of America (i)
pursuant to the terms of an applicable tax treaty in effect with the United
States of America (in which case such certificate shall be accompanied by two
executed copies of IRS Form 1001), or (ii) under Code Section 1441(c) (in which
case such certificate shall be accompanied by two executed copies of IRS Form
4224) (such forms being the "Prescribed Forms").  If requested by the Borrower
from time to time after the Closing Date (upon the obsolescence of any
previously delivered form or otherwise), or if a new form is required by any
applicable Requirement of Law, a Foreign Secured Party shall, to the extent
required thereto under any applicable Requirement of Law, provide to the
Borrower new Prescribed Forms, in each case duly executed and completed by such
Foreign Secured Party. The Borrower shall not be required to indemnify any
Foreign Secured Party or pay any additional amounts to any Foreign Secured
Party pursuant to Sections 2.12(a), 2.12(c) or 2.12(d) to the extent that the
obligation to indemnity such Foreign Secured Party or pay such additional
amounts would not have arisen but for the failure by such Foreign Secured Party
to comply with applicable certification, information or other documentation
requirements concerning the nationality, residency, identity or connection with
the United States of such Foreign Secured Party if such compliance is required
by statute or regulation of the United States as a precondition to relief or
exemption from such amounts payable under, or for which indemnification is
given pursuant to, Sections 2.12(a), (c) or (d); provided, that, the Borrower
shall be required to indemnify each Foreign Secured Party to the extent that
(A) any such payment or indemnification is attributable to an enactment,
promulgation or any change in or interpretation of any Requirement of Law
occurring after the date hereof and (B) such deductions, withholding, payments
or liabilities accrue after the date on which such Secured Party timely
furnishes to the Borrower all Prescribed Forms required to be furnished by this
Section 2.12(e) with respect to such enactment, promulgation or any change in
or interpretation of any Requirement of Law.

                 (f)      Without prejudice to the survival of any other
agreement of the Borrower hereunder, the agreements and obligations of the
Borrower contained in this Section 2.12 shall survive the payment in full of
principal and interest on the Loans hereunder and under the Notes.

                 Section 2.13     Sharing of Payments.  If any Lender shall
obtain any payment (whether voluntary, involuntary, through the exercise of any
right of set-off or otherwise) on account of a Loan made by it in excess of its
Pro Rata Share of payments on account of such Loan obtained by all the Lenders,
such Lender shall forthwith purchase from the other Lenders such participations
in the Loan made by it as shall be necessary to cause such purchasing Lender to
share the excess payment ratably with each of them; provided, that, if all or
any portion of such excess payment is thereafter recovered from such purchasing
Lender, such purchase from each Lender shall be rescinded and each such Lender
shall repay to the purchasing Lender the purchase price to the extent of such
recovery together with an amount equal to such Lender's Pro Rata Share
(according to the proportion of (i) the amount of such Lender's required
repayment to (ii) the total amount so recovered from the purchasing Lender) of
any interest or other amount paid or payable by the purchasing Lender in
respect to the total amount so recovered.  The Borrower agrees that any Lender
so purchasing a participation from another Lender pursuant to this Section 2.13
may, to the fullest extent permitted by law, exercise all its rights of payment
(including the right of set-off) with respect to such participation as fully as
if such Lender were the direct creditor of the Borrower in the amount of such
participation.

<PAGE>   55
                 Section 2.14     Change of Applicable Lending Office.  Without
affecting its rights under Section 2.09(a), 2.09(b), 2.10 or 2.12, each of the
Lenders, the Issuing Bank and the Administrative Agent agrees to use reasonable
efforts (consistent with its internal policy and legal and regulatory
restrictions and so long as such efforts would not be disadvantageous to it, in
its sole opinion) to designate a different Applicable Lending Office if such
redesignation would thereafter eliminate or reduce any amounts that the
Borrower is required to pay to any of the Lenders, the Issuing Bank or the
Administrative Agent pursuant to such Sections; provided, that, in determining,
in its sole opinion, whether designating a different Applicable Lending Office
would be disadvantageous to it, the applicable Lender, the Issuing Bank or the
Administrative Agent, as the case may be, shall disregard any direct financial
loss of making such a designation if the Borrower agrees in form and substance
satisfactory to such Lender, the Issuing Bank or the Administrative Agent, as
the case may be, to indemnify and hold such Lender, the Issuing Bank or the
Administrative Agent, as the case may be, harmless from such financial loss and
provided, further, that any out-of-pocket costs and expenses associated with
such efforts shall be paid or reimbursed by the Borrower.

                 Section 2.15     Replacement of Lenders.  On each occasion
that a Lender either makes a demand for compensation pursuant to Section
2.09(a), 2.09(b) or 2.12 in an amount in excess of the amount that the Borrower
would have had to pay pursuant to such Sections if such Lender's Commitments
were held by a Lender with respect to which no such amounts would then be
payable pursuant to any such Section or is unable for a period of two
consecutive months to fund or maintain LIBO Rate Loans pursuant to Section
2.10, the Borrower may, upon at least ten (10) Business Days' prior written
notice to each of such Lender and the Administrative Agent, in whole
permanently replace the Commitment of such Lender; provided, that, the Borrower
shall replace such Commitment with the commitment of a commercial bank which is
reasonably satisfactory to the Administrative Agent or any other Lender (a
"Replacement Lender").  Such Replacement Lender shall, upon the effective date
of replacement, purchase the Obligations owed to such replaced Lender for the
aggregate amount thereof and shall thereupon for all purposes become a "Lender"
hereunder.  Such notice from the Borrower shall specify an effective date for
the replacement of such Lender's Commitment, which date shall not be earlier
than the tenth (10th) day after the day such notice is given.  On the effective
date of any replacement of such Lender's Commitment pursuant to this Section
2.15, the Borrower shall pay to the Administrative Agent for the account of
such Lender (i) any Fees or other amounts due to such Lender to the date of
such replacement, (ii) accrued interest on the principal amount of outstanding
Loans held by such Lender to the date of such replacement and (iii) the amount
or amounts payable to such Lender pursuant to Section 2.09(a), Section 2.09(b)
or Section 2.12, as applicable.  The Borrower will be liable to such replaced
Lender for costs that such Lender may sustain or incur pursuant to Section
2.09(c) as a direct consequence of repayment of such Lender's Loans. Upon the
effective date of repayment of any Lender's Commitment pursuant to this Section
2.15, such Lender shall cease to be a "Lender" hereunder.  No such termination
of any such Lender's Commitment and the purchase of such Lender's Loans
pursuant to this Section 2.15 shall affect (x) any liability or obligation of
the Borrower or any other Lender to such terminated Lender which accrued on or
prior to the date of such termination or (y) such terminated Lender's rights
hereunder in respect of any such liability or obligation.

                 Section 2.16     ConEd Letter of Credit.

                                       48
<PAGE>   56
                 (a)      The Borrower may request the issuance of the ConEd
Letter of Credit, for the account of the Borrower, at any time during the ConEd
Letter of Credit Availability Period; provided, that, the ConEd Letter of
Credit shall be issued only if (and a request by the Borrower for the issuance
of the ConEd Letter of Credit shall be deemed a representation and warranty of
the Borrower that) immediately following the issuance of the ConEd Letter of
Credit, (i) the ConEd Letter of Credit Exposure shall not exceed $10,000,000,
and (ii) the sum of the aggregate ConEd Letter of Credit Exposure and the
aggregate principal amount of outstanding Working Capital Loans at such time
shall not exceed lesser of (y) the aggregate Working Capital Loan Commitments
at such time and (z) the Working Capital Loan Availability Amount effective as
of such time.

                 (b)      The ConEd Letter of Credit shall expire at 5:00 p.m.,
New York City time, on the last day of the ConEd Letter of Credit Availability
Period, unless the ConEd Letter of Credit expires by its terms (or is required
by Section 2.16(c) to expire) on an earlier date.  The ConEd Letter of Credit
shall provide for payments of drawings in Dollars.

                 (c)      The issuance of the ConEd Letter of Credit shall be
made on at least five Business Days' prior irrevocable written or telecopy
notice (such notice to be delivered by 10:00 a.m., New York City time) from the
Borrower (or such shorter notice as shall be acceptable to the Issuing Bank) to
the Administrative Agent and the Issuing Bank, specifying the date of issuance,
the date on which the ConEd Letter of Credit is to expire (which shall not be
later than the last day of the ConEd Letter of Credit Availability Period and
shall be for such period of time as is contemplated by the form of letter of
credit attached hereto as Exhibit T), the amount of the ConEd Letter of Credit,
the name and address of the beneficiary of the ConEd Letter of Credit, and such
other information as may be necessary or desirable to complete the ConEd Letter
of Credit.  The Issuing Bank will give the Administrative Agent prompt notice
of the issuance and amount of the ConEd Letter of Credit and the expiration
date of the ConEd Letter of Credit (and the Administrative Agent shall give
prompt notice thereof to each Working Capital Lender). The ConEd Letter of
Credit issued hereunder will be subject to the Uniform Customs and Practices
for Documentary Credits, as in effect from time to time.

                 (d)      By the issuance of the ConEd Letter of Credit and
without any further action on the part of the Issuing Bank, the Administrative
Agent or the Working Capital Lenders in respect thereof, the Issuing Bank
hereby grants to each Working Capital Lender, and each Working Capital Lender
hereby acquires from the Issuing Bank, a participation in the ConEd Letter of
Credit equal to such Working Capital Lender's Pro Rata Share (based on such
Working Capital Lender's Working Capital Loan Commitment) of the aggregate
amount available to be drawn under the ConEd Letter of Credit, effective upon
the issuance of the ConEd Letter of Credit.  In consideration and in
furtherance of the foregoing, each Working Capital Lender having a Working
Capital Loan Commitment hereby absolutely and unconditionally agrees to pay to
the Administrative Agent, on behalf of the Issuing Bank, in accordance with
Section 2.03(c), such Working Capital Lender's Pro Rata Share (based on such
Working Capital Lender's Working Capital Loan Commitment) of the ConEd Letter
of Credit Disbursement made by the Issuing Bank and not reimbursed by the
Borrower when due in accordance with Section 2.16(g); provided, that, the
Working Capital Lenders shall not be obligated to make any such payment with
respect to any wrongful Letter of Credit Disbursement made as a result of the
gross negligence or willful misconduct of the Issuing Bank.

                 (e)      Each Working Capital Lender acknowledges and agrees
that its obligation to acquire participations pursuant to Section 2.16(d) in
respect the ConEd Letter of Credit is absolute and unconditional and shall not
be affected by any circumstance whatsoever, including the occurrence and
continuance of a Default or Event of Default, and that each such payment shall
be made without any offset, abatement, withholding or reduction whatsoever
(subject only to the proviso set forth in the last sentence of Section
2.16(d)).

                 (f)      During the ConEd Letter of Credit Availability
Period, from and after the date on which the ConEd Letter of Credit is issued,
the Borrower shall pay to the Administrative Agent, on each Quarterly Payment
Date in each year and on the date on which the Working Capital Loan Commitments
shall be terminated as provided herein, (i) for the account of the Working
Capital Lenders, ratably in proportion to their Working Capital Loan
Commitments, a fee on the average daily aggregate amount available to be drawn
under the ConEd Letter of Credit during the preceding quarter (or shorter
period commencing with the Closing Date) at a rate per annum equal to the
applicable LIBO Rate Margin from time to time in effect during such period
pursuant to Section 2.06 and (ii) for the account of the Issuing Bank, a fee on
the average daily aggregate amount available to be drawn under the ConEd Letter
of Credit during the preceding quarter (or shorter period commencing with the
Closing Date) at a rate per annum equal to 0.25%.  Such fees shall be computed
on the basis of the actual number of days elapsed in a year of 360 days.  Such
fees shall accrue from and including the Acquisition Loan Funding Date in
respect of the Astoria Bundle to but excluding the last day of the ConEd Letter
of Credit Availability Period. In addition to the foregoing, the Borrower shall
pay directly to the Issuing Bank, for its account, payable within 15 days after
written demand therefor by the Issuing Bank has been received by the Borrower,
the Issuing Bank's out-of-pocket expenses in connection with the issuance,
transfer or amendment of or payment on the ConEd Letter of Credit.

                 (g)      The Borrower hereby agrees to reimburse the Issuing
Bank for any payment or disbursement made by the Issuing Bank under the ConEd
Letter of Credit, by making payment in immediately available funds to the
Administrative Agent within one Business Day after receipt of notice of such
payment or disbursement, in an amount equal to the amount of such payment or
disbursement, plus interest on the amount so paid or disbursed by the Issuing
Bank, to the extent not reimbursed prior to 12:00 p.m.  (New York City  time)
on the date of such payment or disbursement, from and including the date paid
or disbursed to but excluding the date the Issuing Bank is reimbursed by the
Borrower therefor, at a rate per annum equal to the rate applicable to Base
Rate Working Capital Loans during such period pursuant to Section 2.06.  In the
event the Borrower fails to reimburse the Issuing Bank as required by the
preceding sentence, the Issuing Bank shall so notify the Administrative Agent
and such payment or disbursement shall be reimbursed to the Issuing Bank as
contemplated by Section 2.03(c) or Section 2.16(d), as applicable.  The Issuing
Bank shall give the Borrower prompt notice of each drawing under the ConEd
Letter of Credit, provided, that, the failure to give any such notice shall in
no way affect, impair or diminish the Borrower's obligations hereunder.  The
Administrative Agent shall promptly pay any such amounts received by it to the
Issuing Bank.

                 (h)      The Borrower's obligation to reimburse ConEd Letter
of Credit Disbursements as provided in Section 2.16(g) shall be absolute,
unconditional and irrevocable and shall be performed strictly in accordance
with the terms of this Agreement under any and all circumstances, including the
following:

<PAGE>   58
                          (i)     any lack of validity or enforceability of the
                 ConEd Letter of Credit or any other Financing Document;

                          (ii)    except as otherwise provided in clause (iv)
                 of this Section 2.16(h), the existence of any claim, setoff,
                 defense or other right which the Borrower, any Subsidiary or
                 any other person may at any time have against the beneficiary
                 under the ConEd Letter of Credit, the Issuing Bank, the
                 Administrative Agent, any Working Capital Lender or any other
                 person in connection with this Agreement, any other Financing
                 Document or any other related or unrelated agreement or
                 transaction;

                          (iii)   any draft or other document presented under
                 the ConEd Letter of Credit proving to be forged, fraudulent,
                 invalid or insufficient in any respect or failing to comply
                 with the Uniform Customs and Practices for Documentary
                 Credits, as in effect from time to time, or any statement
                 therein being untrue or inaccurate in any respect;

                          (iv)    payment by the Issuing Bank under the ConEd
                 Letter of Credit against presentation of a draft or other
                 document which does not comply with the terms of the ConEd
                 Letter of Credit; provided, that, such payment was not
                 wrongfully made as a result of the gross negligence or willful
                 misconduct of the Issuing Bank;

                          (v)     any amendment, waiver or consent in respect
                 of this Agreement or any other Financing Document; and

                          (vi)    any other act or omission or delay of any
                 kind or any other circumstance or event whatsoever, whether or
                 not similar to any of the foregoing and whether or not
                 foreseeable, that might, but for the provisions of this
                 Section 2.16(h), constitute a legal or equitable discharge of
                 the Borrower's obligations hereunder.

                 (i)      It is expressly understood and agreed that, for
purposes of determining whether a wrongful payment under the ConEd Letter of
Credit resulted from the Issuing Bank's gross negligence or willful misconduct,
(i) the Issuing Bank's acceptance of documents that appear on their face to
comply with the requirements of the ConEd Letter of Credit, without
responsibility for further investigation, regardless of any notice or
information to the contrary, (ii) the Issuing Bank's exclusive reliance on the
documents presented to it under the ConEd Letter of Credit as to any and all
matters set forth therein, including the amount of any draft presented under
the ConEd Letter of Credit, whether or not the amount due to the beneficiary
thereunder equals the amount of such draft and whether or not any document
presented pursuant to the ConEd Letter of Credit proves to be insufficient in
any respect (so long as such document on its face appears to comply with the
requirements of the ConEd Letter of Credit), and whether or not any other
statement or any other document presented pursuant to the ConEd Letter of
Credit proves to be forged or invalid or any statement therein proves to be
inaccurate or untrue in any respect whatsoever and (iii) any noncompliance in
any immaterial respect of the documents presented under the ConEd Letter of
Credit with the terms thereof shall, in each case, be deemed

                                       51
<PAGE>   59
not to constitute willful misconduct or gross negligence of the Issuing Bank.
It is further understood and agreed that, notwithstanding the proviso to clause
(iv) of Section 2.16(h), the Borrower's obligation hereunder to reimburse
Letter of Credit Disbursements will not be excused by the gross negligence or
willful misconduct of the Issuing Bank to the extent that the ConEd Letter of
Credit Disbursement actually discharged a liability of, or otherwise benefited,
or was recovered by, the Borrower; provided, that, the foregoing shall not be
construed to excuse the Issuing Bank from liability to the Borrower to the
extent of any direct damages suffered by the Borrower that are caused by the
Issuing Bank's gross negligence or willful misconduct in determining whether
drafts and other documents presented under the ConEd Letter of Credit comply
with the terms thereof.

                 (j)      The Issuing Bank shall, promptly following its
receipt thereof, examine all documents purporting to represent a demand for
payment under the ConEd Letter of Credit.  The Issuing Bank shall as promptly
as possible give telephonic notification, confirmed by telex or telecopy, to
the Administrative Agent and the Borrower of such demand for payment and
whether the Issuing Bank has made or will make the ConEd Letter of Credit
Disbursement thereunder; provided, that, the failure to give such notice shall
not relieve the Borrower of its obligation to reimburse any the ConEd Letter of
Credit Disbursement in accordance with this Section 2.16.  The Administrative
Agent shall promptly give each Working Capital Lender notice thereof.

                 (k)      The Borrower shall use the ConEd Letter of Credit
solely to support its obligations under the ConEd Guarantee Agreement as
required thereby.

                 (l)      In the event that the Borrower is required pursuant
to the terms of this Agreement to provide cash collateral in respect of the
ConEd Letter of Credit Exposure, the Borrower shall deposit in an account with
the Administrative Agent, for the benefit of each Lender having a Working
Capital Loan Commitment, an amount in cash equal to the ConEd Letter of Credit
Exposure (or such lesser amount as shall be required hereunder or thereunder).
Such deposit shall be held by the Administrative Agent as collateral for the
payment and performance of any outstanding ConEd Letter of Credit Exposure.
The Administrative Agent shall have exclusive dominion and control, including
the exclusive right of withdrawal, over such account.  Moneys in such account
shall be held and applied by the Administrative Agent in accordance with the
Deposit Account Agreement.

action, suit, arbitration, litigation, investigation or proceeding of or before
any arbitrator or Governmental Authority pending against (i) any Borrower
Entity or, to the Borrower's knowledge, threatened against any Borrower Entity
nor, to the Borrower's knowledge, is there any reasonable basis for any such
action, suit arbitration, litigation, investigation or proceeding, or, (ii) to
the Borrower's knowledge, pending or threatened against any other Major Project
Party, which, solely with respect to this clause (ii), could reasonably be
expected to result in a material adverse affect on the financial condition of

payable by it which have become due, other than those not yet delinquent and
except for those being contested in good faith and by appropriate proceedings
and for which Acceptable Reserves have been established.  No tax Liens have

any such taxes or other charges.

                 Section 4.10     Use of Proceeds.  All proceeds of the Loans

payment to any Plan or Multiemployer Plan or in respect of any Benefit
Arrangement, or made any amendment to any Plan or Benefit Arrangement, which in
either case would trigger the provisions of Section 412(n) or 401(a)(29) of the
Code (or any corresponding provisions of ERISA) or (c) incurred any liability
under Title IV of ERISA other than a liability to the PBGC for premiums under
Section 4007 of ERISA.

                 Section 4.12     Material Liabilities.  No Borrower Entity has
any material liabilities (actual or contingent) other than those (a) existing

most recent financial statements or in the Operating Budget, (b) arising out
of, or expressly permitted by, this Agreement or the other Transaction
Documents to which it is, or is to become, a party or (c) liabilities incurred,
existing or assumed after the Closing Date pursuant to written agreements,
contracts, commitments and/or arrangements of any Borrower Entity, entered into
in the ordinary course of business permitted pursuant to the Financing
Documents and which individually or in the aggregate would not reasonably

hereby or by any other Transaction Document, or as a result of the ownership,
use or operation of the Portfolio Assets, subject to regulation by the
Securities and Exchange Commission as a "public-utility company," an "electric
utility company," a "holding company" or a "subsidiary" or "affiliate" of any
of the foregoing under PUHCA.  So long as the owner and each operator of the
Portfolio Assets is an "exempt wholesale generator" under Section 32 of PUHCA,
none of the Lenders will, solely as a result of its or their ownership or
operation of the Portfolio Assets upon the exercise of remedies under the
Security Documents, be subject to regulation by the Securities and Exchange
Commission as a "public-utility company," an "electric utility company," a

enforceable Liens in and on all of the Collateral described in each such
Security Document in favor of the Administrative Agent (for the benefit of the
Secured Parties), and upon making the filings referenced in Schedule 4.14
hereof in the applicable filing or recording office in accordance with
applicable Requirements of Law, all necessary and appropriate recordings and
filings will have been made, and, upon taking possession of the equity security
and accompanying stock powers to be delivered to the Administrative Agent
pursuant to the Stock Pledge Agreement all other necessary and appropriate
action has been taken so that each such Security Document creates a perfected
Lien (other than with respect to vehicles or any emergency response boat) on
and security interest in the Collateral covered thereby and appropriate
consents to the action, perfection and enforcement of such Liens have been
obtained from each of the Project Parties superior to and prior to the rights
of all other Persons, subject only to Permitted Liens.  All taxes, fees and
other charges payable in connection therewith will have either been paid in
full by the Borrower or arrangements for the payment of such amounts
satisfactory to the Administrative Agent shall have been made.

furnished by or on behalf of any Credit Party to the Lead Arrangers, the
Administrative Agent or any Lender will be, true and accurate in all material
respects on the date as of which such information is given, dated or certified
and not incomplete by omitting to state any material fact necessary to make
such information not materially misleading at such time, in each case taken as
a whole together with all other information theretofore or contemporaneously
supplied; provided, that, no representation or warranty is made with regard to
(a) any projections or other forward- looking statements provided by the
Borrower, including the Projections (except as set forth in Section 4.26 below)

furnished by or on behalf of any Person (other than any Credit Party) to the
Lead Arrangers, the Administrative Agent or any Lender, for purposes of, or in
connection with, this Agreement, any other Transaction Document or any
transaction contemplated hereby or thereby.  To the knowledge of the Borrower
based on such inquiry, all such factual information is true and accurate in all
material respects on the date as of which such information is given, dated or
certified and is not incomplete by omitting to state any material fact
necessary to make such information not materially misleading at such time, in
each case taken as a whole together with all other information theretofore or
contemporaneously supplied.

                 (c)      There is no fact known to any Credit Party which has,

Project Contracts or are otherwise commercially available to the Borrower
Entities and the Portfolio Assets and, to the extent appropriate, arrangements

                 (c)      Hazardous Materials have not at any time been used or
Released by any Borrower Entity or, to the Borrower's knowledge, by any other
Person, at, on, under or from the Portfolio Assets other than in compliance at

of the Closing Date, no Hazardous Material generated by any Borrower Entity has
been recycled, treated, stored, disposed of or Released by any Borrower Entity
at any location other than those listed in Schedule 4.20.

                 (d)      (i) there are not now and, to the Borrower's
knowledge after reasonable inquiry, never have been any underground storage
tanks located at the sites of any of the Portfolio Assets, (ii) there is no

Entity have been made available to the Lenders.

                 (f)      No Borrower Entity has transported or contractually
permitted for the transportation of any Hazardous Material to any location that
is listed on the National Priorities List ("NPL") under the Comprehensive
Environmental Response, Compensation and Liability Act of 1980, as amended
("CERCLA"), listed for possible inclusion on the NPL by the Environmental
Protection Agency in the Comprehensive Environmental Response and Liability

                 (h)      (i)  No Liens have arisen under or pursuant to any
Environmental Laws on the Portfolio Assets or any site or facility that will be
owned, operated or leased by any Borrower Entity, and (ii) no government action

relating to the presence of Hazardous Materials at any of the Portfolio Assets

on which any of the Portfolio Assets or such site or facility is located.

                 (i)      The Portfolio Assets are in compliance with all
Environmental Laws and, to the Borrower's knowledge after reasonable inquiry,
there is no reason to believe that there are any facts or circumstances that
will materially limit the continued compliance of the operation of the
Portfolio Assets with all Environmental Laws or which would require material
changes to the Portfolio Assets, or the operation thereof, to comply with
Environmental Laws in the future, except in any such case where such
non-compliance could not be reasonably expected to materially adversely effect
the operation or performance of a material portion of the NiMo Assets or any
other Portfolio Asset that  is the subject of such non-compliance, it being

individually, a material portion of the NiMo Assets.

Borrower to be Year 2000 Compliant on a timely basis (and in any event, prior
to December 31, 1999) (ii) developed a detailed plan and timeline for becoming
Year 2000 Compliant on a timely basis, and (iii) implemented that plan in
accordance with that timetable in all material respects.

                 (b)      Borrower has developed a plan and timeline for making
written inquiry of each of the Major Project Parties and the Sponsor as to
whether such persons will be Year 2000 Compliant in all material respects and
has materially implemented that plan in accordance with that timetable.

                 (c)      Based on the foregoing, Borrower reasonably believes
that it will be Year 2000 Compliant on a timely basis.

caused to be prepared the Projections and is responsible for developing the
assumptions on which the Projections are based.  The Projections are, to the
Borrower's knowledge after reasonable inquiry (a) based on reasonable
assumptions, including all legal and factual matters material to the estimates
set forth therein, and (b) consistent with the provisions of the Transaction
Documents; provided, that each of the Secured Parties hereby acknowledges and
agrees that such Projections may or may not prove to be correct and that no
representation or warranty is made as to whether actual performance of the
Portfolio Assets is or will be accurately reflected in such Projections.

                 Section 4.27     Environmental Insurance.

                 (a)      To the Borrower's knowledge after reasonable inquiry,

                 (b)      The Borrower reasonably believes, based on reasonable
assumptions, that a reasonable estimate of the amount necessary to complete the
Remedial Action Plan is $9,134,508.  The Borrower reasonably believes, based on
reasonable assumptions that the Remedial Action Plan includes all actions
necessary to cleanup, investigate, remediate and monitor all Hazardous
Materials identified therein it being acknowledged and agreed that any actual
remedial action plan effected by any Borrower Entity may differ from the
Remedial Action Plan and may change or be altered over time and is subject to
the interpretation and administration of applicable Requirements of Law by
applicable governmental officials; provided that any difference, change or
alteration shall comply with the Cost Cap Policy requirements.

                 (c)      The Borrower reasonably believes, based on reasonable
assumptions, that a reasonable estimate of the amount necessary to pay the
applicable deductibles under the PLL Policy for the cleanup, investigation,
remediation and monitoring of any Hazardous Materials existing in, on, under or
from the Portfolio Assets on or before the date hereof which, to the Borrower's
knowledge after reasonable inquiry, the Borrower believes may reasonably be
expected to be required under the Environmental Laws and not excluded from
coverage under the PLL Policy is $635,000.

                             AFFIRMATIVE COVENANTS

                 The Borrower covenants and agrees that, so long as this

longer required for the business of any Borrower Entity), ordinary wear and

distribution, nature of business, management, transfer of interests or powers
of the general partner provisions thereof.

                 Section 5.02     Governmental Approvals.  Duly obtain on, or

written, telecopied or telex request of the Required Lenders, shall, by written
notice to the Credit Parties (a "Remedy Notice"), take any or all of the
following actions, without prejudice to the rights of the Administrative Agent,
any Secured Party or the holder of any Note to enforce its claims against the
Borrower: (i)

                                       89
<PAGE>   97
declare the Commitments terminated, whereupon the Commitments of each Lender
shall terminate immediately and any accrued but unpaid Commitment Fee shall
forthwith become due and payable without any action of any kind; or (ii)
declare the principal of and any accrued interest on the Loans, and all other
Obligations, to be, whereupon the same shall become, forthwith due and payable
without presentment, demand, protest or other notice of any kind, all of which
are hereby waived; provided that, if any Event of Default specified in Section
7.07 shall occur, the result which would occur upon the giving of a Remedy
Notice by the Administrative Agent, as specified in clauses (i) and (ii) above,
shall occur automatically without the giving of any such Notice.  Except as
expressly provided in the immediately preceding sentence, neither the
Administrative Agent nor any Secured Party shall otherwise be precluded from
pursuing any other right or remedy then available to them against the Borrower
or any Credit Party pursuant to the Financing Documents.  Upon the exercise of
any of the foregoing remedies, any excess remaining after payments to each
Secured Party of any and all amounts sufficient to compensate such Secured
Party for all amounts owing and all costs incurred under any Financing
Document, shall be remitted by the Administrative Agent to the Borrower.

                                  ARTICLE VIII

                   THE ADMINISTRATIVE AGENT AND ISSUING BANK

                 Section 8.01     Appointment of Administrative Agent, Powers
and Immunities.  Each Secured Party hereby irrevocably appoints and authorizes
the Administrative Agent and the Issuing Bank to act as its Administrative
Agent and the Issuing Bank hereunder and under the other Transaction Documents
with such powers as are expressly delegated to the Administrative Agent and the
Issuing Bank by the terms of this Agreement, together with such other powers as
are reasonably incidental thereto. The Administrative Agent shall not have any
duties or responsibilities except those expressly set forth in this Agreement
or in any other Transaction Document, or be a trustee for any Secured Party.
Notwithstanding anything to the contrary contained herein, the Administrative
Agent shall not be required to take any action which is contrary to this
Agreement or any other Transaction Document or applicable law.  Neither the
Administrative Agent, the Issuing Bank nor any Secured Party nor any of their
respective affiliates shall be responsible to any other Secured Party for any
recitals, statements, representations or warranties made by the Borrower
contained in this Agreement or any other Transaction Document or in any
certificate or other document referred to or provided for in, or received by
any Secured Party under, this Agreement or any other Transaction Document, for
the value, validity, effectiveness, genuineness, enforceability or sufficiency
of this Agreement, the Notes, the other Transaction Documents or any other
document referred to or provided for herein or therein or for any failure by
the Borrower to perform its obligations hereunder or thereunder.  The
Administrative Agent may employ Administrative Agents and attorneys-in-fact and
shall not be responsible for the negligence or misconduct of any such
Administrative Agents or attorneys-in-fact selected by it with reasonable care.
Neither the Administrative Agent, the Issuing Bank nor any of their respective
directors, officers, employees or agents shall be responsible for any action
taken or omitted to be taken by it or them hereunder or under any other
Transaction Document or in connection herewith or therewith, except for its or
their own gross negligence or willful misconduct.

                                       90
<PAGE>   98
                 Section 8.02     Reliance by Administrative Agent.  The
Administrative Agent and the Issuing Bank shall be entitled to rely upon any
certificate, notice or other document (including any cable, telegram, telecopy
or telex) believed by it to be genuine and correct and to have been signed or
sent by or on behalf of the proper Person or Persons, and upon advice and
statements of legal counsel, independent accountants and other experts selected
by the Administrative Agent or the Issuing Bank.  As to any matters related to
this Agreement or the transactions contemplated hereby, neither the
Administrative Agent nor the Issuing Bank shall be required to take any action
or exercise any discretion, but the Administrative Agent and the Issuing Bank
shall be required to act or to refrain from acting upon instructions of the
Required Lenders and shall in all cases be fully protected in acting, or in
refraining from acting, hereunder or under any other Transaction Document in
accordance with the instructions of the Required Lenders, and such instructions
of the Required Lenders and any action taken or failure to act pursuant thereto
shall be binding on all of the Secured Parties.

                 Section 8.03     Defaults.  The Administrative Agent shall not
be deemed to have actual knowledge or notice of the occurrence of a Default or
an Event of Default unless the Administrative Agent has received notice from a
Lender or the Borrower referring to this Agreement, describing such Default or
Event of Default and stating that such notice is a "Notice of Default".  In the
event that the Administrative Agent receives such a notice of the occurrence of
a Default or an Event of Default the Administrative Agent shall give notice
thereof to the Secured Parties.  The Administrative Agent shall take such
action with respect to such Default or Event of Default as shall be reasonably
directed by the Required Lenders; provided that, unless and until the
Administrative Agent shall have received such directions, the Administrative
Agent may (but shall not be obligated to) take such action, or refrain from
taking such action, with respect to such Default or Event of Default as it
shall deem advisable in the best interest of the Secured Parties.

                 Section 8.04     Rights as Lenders.  With respect to its
commitment to make Loans, Bank of America, N.A. shall have the same rights and
powers hereunder as any Lender and may exercise the same as though it was not
acting as the Administrative Agent and the term "Lender" or "Lenders" shall,
unless the context otherwise indicates, include Bank of America, N.A. in its
individual capacity.  Bank of America, N.A. and its Affiliates may (without
having to account therefor to any Lender) accept deposits from, extend credit
(on a secured or unsecured basis) to and generally engage in any kind of
banking, trust or other business with the Borrower or any of its Affiliates, as
if it were not acting as the Administrative Agent.

                 Section 8.05     Indemnification.  Without limiting the
obligations of the Borrower under Section 9.04 hereof, each Lender agrees to
indemnify the Administrative Agent, the Issuing Bank and the Lead Arrangers,
ratably in accordance with the aggregate principal amount of the Loans and
ConEd Letter of Credit Exposure held by the Lenders, or, if no Loans are then
outstanding, the respective amounts of the Lenders' Commitments, for any and
all liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements or any kind or nature whatsoever which
may at any time (including, without limitation, at any time following the
payment of principal of and/or interest on the Loans) be imposed on, incurred
by or asserted against the Administrative Agent, the Issuing Bank or either
Lead Arranger in any way relating to or arising out of this Agreement or any
documents contemplated by or referred to herein or therein or the transactions
contemplated hereby or

                                       91
<PAGE>   99
thereby (including the costs and expenses which the Borrower is obligated to
pay under Section 9.04 hereof) or the enforcement of any of the terms hereof or
thereof or of any such other documents, provided that no Lender shall be liable
for any of the foregoing to the extent they arise from the Administrative
Agent's, the Issuing Bank's or either Lead Arranger's gross negligence or
willful misconduct as determined by a court of competent jurisdiction.  The
Administrative Agent, the Issuing Bank and the Lead Arrangers shall be fully
justified in refusing to take or to continue to take any action hereunder
unless it shall first be indemnified to its satisfaction by the Lenders against
any and all liability and expense which may be incurred by it by reason of
taking or continuing to take any such action.

                 Section 8.06     Documents.  The Administrative Agent will
forward to each Lender, promptly after the Administrative Agent's receipt
thereof, a copy of each document furnished to the Administrative Agent for such
Secured Party hereunder (and a copy of such other documents furnished to the
Administrative Agent pursuant to Article III hereof as may be requested by such
Lender).

                 Section 8.07     Non-Reliance on Administrative Agent and
Other Lenders.  Each Lender represents that it has, independently and without
reliance on the Administrative Agent, the Issuing Bank, any Lead Arranger, or
any other Lender, and based on such documents and information as it has deemed
appropriate, made its own appraisal of the financial condition and affairs of
the Borrower and its own decision to enter into this Agreement and agrees that
it will, independently and without reliance upon the Administrative Agent, the
Issuing Bank, any Lead Arranger or any other Lender, and based on such
documents and information as it shall deem appropriate at the time, continue to
make its own appraisals and decisions in taking or not taking action under this
Agreement.  None of the Administrative Agent, the Issuing Bank, any Lead
Arranger or any Lender shall be required to keep informed as to the performance
or observance by the Borrower under this Agreement or any other document
referred to or provided for herein or to make inquiry of, or to inspect the
properties or books of, the Borrower.  Except for notices, reports and other
documents and information expressly required to be furnished to the Lenders by
the Administrative Agent, the Issuing Bank, or any Lead Arranger hereunder,
none of the Administrative Agent, the Issuing Bank, any Lead Arranger or any
Lender shall have any duty or responsibility to provide any Lender with any
credit or other information concerning the Borrower, or any Affiliate of the
Borrower, which may come into the possession of the Administrative Agent, the
Issuing Bank, any Lead Arranger or such Lender or any of its or their
Affiliates.

                 Section 8.08     Resignation.  Subject to the appointment and
acceptance of a successor as provided below, each of the Administrative Agent
and the Issuing Bank (prior to the issuance of the ConEd Letter of Credit) may
resign at any time by giving notice thereof to the Lenders and the Borrower.
Upon any such resignation, the Required Lenders shall have the right to appoint
a successor Administrative Agent and/or Issuing Bank, as applicable, which
shall be a Lender hereunder.  If no successor Administrative Agent and/or
Issuing Bank, as applicable, shall have been appointed by the Required Lenders
and no Lender shall have accepted such appointment within 30 days after the
retiring Administrative Agent's and/or Issuing Bank's giving of notice of
resignation, then the retiring Administrative Agent may, on behalf of the
Lenders, appoint a successor Administrative Agent and/or Issuing Bank, which
shall be a Lender hereunder  having a combined capital and surplus of not less
than $500,000,000.  Upon the

                                       92
<PAGE>   100
acceptance of any appointment as Administrative Agent and/or Issuing Bank, as
applicable, hereunder by a successor Administrative Agent and/or Issuing Bank,
as the case may be, such successor Administrative Agent and/or Issuing Bank
shall thereupon succeed to and become  vested with all the rights, powers,
privileges and duties of the retiring Administrative Agent and/or Issuing Bank,
and the retiring Administrative Agent and/or Issuing Bank shall be discharged
from its duties and obligations hereunder.  After any retiring Administrative
Agent's and/or Issuing Bank's resignation hereunder as Administrative Agent
and/or Issuing Bank, the provisions of this Article VIII shall continue in
effect for its benefit in respect of any actions taken or omitted to be taken
by it while it was acting as Administrative Agent and/or Issuing bank.

                 Section 8.09     Authorization.  The Administrative Agent and
the Issuing Bank are hereby authorized by the Lenders to execute, deliver and
perform each of the Transaction Documents to which they (whether as
"Administrative Agent", "Issuing Bank", "Secured Party", "Grantee" or
"Mortgagee") are or are intended to be a party and each Lender agrees to be
bound by all of the agreements of the Administrative Agent and the Issuing Bank
respectively, contained in the Transaction Documents.

                                   ARTICLE IX

                                 MISCELLANEOUS

                 Section 9.01     Notices.  All notices, requests and other
communications to the Borrower or any Secured Party shall be in writing
(including bank wire, cable, telex, telecopy or similar teletransmission or
writing) and shall be given to such party at its address, or telex, cable or
telecopy number set forth on Annex II hereto or such other address or telecopy
number as such party may hereafter specify by notice to the Administrative
Agent and the Borrower.  Each such notice, request or other communication shall
be effective (i) if given by telecopy, when such telecopy is transmitted to the
telecopy number specified in Annex II and receipt thereof is confirmed in
writing, or (ii) if given by any other means (including, without limitation, by
air courier), when delivered at the address specified in Annex II.

                 Section 9.02     Amendments, Etc..  No amendment or waiver of
any provision of any Financing Document, nor consent to any departure by any
Credit Party therefrom, shall in any event be effective unless the same shall
be in writing and signed by the Required Lenders, or if the Lenders shall not
be parties thereto, by the parties thereto and consented to by the Required
Lenders, and each such amendment, waiver or consent shall be effective only in
the specific instance and for the specific purpose for which given; provided,
that, no amendment, waiver or consent shall, unless in writing and signed by
all the Lenders, do any of the following: (i) increase the Commitments of the
Lenders or subject the Lenders to any additional obligations, (ii) reduce the
principal of, or interest on, the Notes or any Fees hereunder, (iii) postpone
any date fixed for any payment in respect of principal of, or interest on, the
Notes or any Fees hereunder, (iv) change the percentage of the Commitments or
of the aggregate unpaid principal amount of the Notes, or the number or
identity of the Lenders which shall be required for the Lenders or any of them
to take any action hereunder, (v) postpone the date fixed for reimbursement of
any ConEd Letter of Credit Disbursement, (vi) amend or waive Sections 9.02,

                                       93
<PAGE>   101
9.04 or the definitions of the terms used in such Sections under any Financing
Document insofar as the definitions affect the substance of such Sections,
(vii) consent to the assignment or other transfer by any Credit Party of any of
its rights and obligations under any Financing Document, (viii) release any
Collateral (other than as expressly contemplated under the Financing Documents)
or the Subsidiary Guarantee, (ix) extend either the Acquisition Loan
Availability Period or the Working Capital Loan Availability Period, or (x)
subordinate the Loans to any other Indebtedness; and provided, further, that no
amendment, waiver or consent affecting the rights or duties of the
Administrative Agent or the Issuing Bank under any Financing Document shall in
any event be effective, unless in writing and signed by the Administrative
Agent or the Issuing Bank, as the case may be, in addition to the Lenders
required hereinabove to take such action. Notwithstanding any of the foregoing
to the contrary, the consent of the Borrower shall not be required for any
amendment, modification or waiver of the provisions of Article VIII (other than
the provisions of Section 8.08).  In addition, the Borrower, the Lead
Arrangers, the Lenders and the Swap Banks hereby authorize the Administrative
Agent to modify this Agreement by amending or supplementing Annexes I and II
from time to time in the manner requested by the Borrower, the Administrative
Agent or any other Secured Party and otherwise in accordance with the terms of
this Agreement; provided, however, that the Administrative Agent shall promptly
deliver a copy of any such modification to the Borrower and each Secured Party.

                 Section 9.03     No Waiver; Remedies Cumulative.  No failure
or delay on the part of any Secured Party or any holder of a Note in exercising
any right or remedy under any Financing Document and no course of dealing
between the Borrower and any Secured Party or the holder of any Note shall
operate as a waiver thereof, nor shall any single or partial exercise of any
right or remedy under any Financing Document preclude any other or further
exercise thereof or the exercise of any other right or remedy hereunder.  The
rights and remedies herein expressly provided are cumulative and not exclusive
of any rights or remedies which the Secured Parties or the holder of any Note
would otherwise have.  No notice to or demand on the Borrower not required
under any Financing Document shall entitle the Borrower to any other or further
notice or demand in similar or other circumstances or constitute a waiver of
the rights of any Secured Party or the holder of any Note to any other or
further action in any circumstances without notice or demand.

                 Person.

                 (b)      If and to the extent that the obligations of the
Borrower under this Section 9.04 are unenforceable for any reason, the Borrower
hereby agrees to make the maximum contribution to the payment and satisfaction
of such obligations which is permissible under applicable Requirement of Law.
The Borrower's obligations under this Section 9.04 shall survive any
termination of this Agreement and the payment of the Notes.

                 Section 9.05     Right of Setoff.  In addition to and not in
limitation of all rights of offset that any Lender or other holder of a Note
may have under applicable Requirement of Law, each Lender or other holder of a
Note shall, upon the occurrence and during the continuance of any Event of
Default and whether or not such Lender or such holder has made any demand or
the Obligations of the Borrower are matured, have the right to appropriate and
apply to the payment of the Obligations of the Borrower all deposits (general
or special, time or demand, provisional or final) then or thereafter held by
and other indebtedness or property then or thereafter owing by such Lender or
other holder, whether or not related to this Agreement or any transaction
hereunder.  Any amount received as a result of the exercise of such rights
shall be re-allocated among the Lenders as set forth in Section 2.13 and the
Borrower shall receive prompt notice thereof from the Administrative Agent;
provided, that any failure by the Administrative Agent to provide such notice
shall in no way affect the rights of any Lender or other holder of a Note under
this Section 9.05.

Participations.

                 (a)      This Agreement shall be binding upon and inure to the
benefit of and be enforceable by the respective successors and assigns of the
parties hereto; provided that the Borrower may not assign or transfer any of
its interest hereunder without the prior written consent of the Lenders.

                 (b)      Any Lender may make, carry or transfer Loans at, to
or for the account of, any of its branch offices or the office of an Affiliate
of such Lender except to the extent such transfer would result in increased
costs to the Borrower.

                 (c)      Each Lender may assign (with the consent of the
Administrative Agent after consultation with the Borrower) to one or more banks
or other entities all or a portion of its rights and obligations under this
Agreement, the Notes and the ConEd Letter  of Credit; provided that (i) no such
assignment shall be for less than $5,000,000 of such Lender's Commitments or
Loans, as the case may be, and (ii) each assignment shall be of a pro rata
portion of such Lender's Commitments or Loans.  Upon such execution, delivery
and acceptance, from and after the effective date (the "Effective Date") of
such Assignment and Acceptance (x) the assignee thereunder shall be a party
hereto, and, to the extent that rights and obligations hereunder have been
assigned to and assumed by it pursuant to such Assignment and Acceptance, such
assignee shall have the rights and obligations of a Lender hereunder and (y)
the Lender assignor thereunder shall, to the extent that rights and obligations
hereunder have been assigned by it pursuant to such Assignment and Acceptance,
relinquish its rights and be released from its obligations under this Agreement
(and, in the case of an Assignment and Acceptance covering all or the remaining
portion of an assigning Lender's rights and obligations under this Agreement,
such Lender shall cease to be a party hereto).

                 (d)      By executing and delivering an Assignment and
Acceptance, the assignee thereunder confirms and agrees as follows: (i) other
than as provided in such Assignment and Acceptance, the assigning Lender makes
no representation or warranty and assumes no responsibility with respect to any
statements, warranties or representations made in or in connection with this
Agreement or the execution, legality, validity, enforceability, genuineness,
sufficiency or value of this Agreement, the Notes, the ConEd Letter of Credit
or any other instrument or document furnished pursuant hereto, (ii) such
assigning Lender makes no representation or warranty and assumes no
responsibility with respect to the financial condition of the Borrower or any
other Credit Party or the performance or observance by the Borrower or any
other Credit Party of any of its obligations under this Agreement, any other
Financing Document or Transaction Document or any other instrument or document
furnished pursuant hereto or thereto, (iii) such assignee confirms that it has
received a copy of this Agreement, together with copies of the financial
statements referred to in Section 5.10 and such other documents and information
as it has deemed appropriate to make its own credit analysis and decision to
enter into such Assignment and Acceptance, (iv) such assignee will,
independently and without reliance upon the Lead  Arrangers, the Administrative
Agent, the Issuing Bank, such assigning Lender or any other Lender and based on
such documents and information as it shall deem appropriate at the time,
continue to make its own credit decisions in taking or not taking action under
this Agreement, (v) such assignee appoints and authorizes the Administrative
Agent to take such action as agent on its behalf and to exercise such powers
under this Agreement and the other Financing Documents as are delegated to the
Administrative Agent by the terms hereof, together with such powers as are
reasonably incidental thereto and (vi) such assignee agrees that

                                       97
<PAGE>   105
it will perform in accordance with their terms all of the obligations which by
the terms of this Agreement are required to be performed by it as a Lender.

                 (e)      The Administrative Agent shall maintain at its
address referred to in Section 9.01 a copy of each Assignment and Acceptance
delivered to and accepted by it and a register for the recordation of the names
and addresses of the Lenders and the Commitments of, and principal amount of
the Loans owing to, each Lender from time to time (the "Register").  The
entries in the Register shall be conclusive and binding for all purposes,
absent manifest error, and the Borrower and each Secured Party may treat each
Person whose name is recorded in the Register as a Lender hereunder for all
purposes of this Agreement.  The Register and copies of each Assignment and
Acceptance shall be available for inspection by the Borrower, the Issuing Bank
or any Lender at any reasonable time and from time to time upon reasonable
prior notice.

                 (f)      Upon its receipt of an Assignment and Acceptance
executed by an assigning Lender, together with the Note or Notes subject to
such assignment, the Administrative Agent shall, if such Assignment and
Acceptance has been completed and is in substantially the form of Exhibit O
hereto, (i) accept such Assignment and Acceptance, (ii) record the information
contained therein in the Register and (iii) give prompt notice thereof to the
Issuing Bank and the Borrower.  Within five (5) Business Days after its receipt
of such notice, the Borrower shall execute and deliver to the Administrative
Agent in exchange for the surrendered Note or Notes a new Note or Notes to the
order of such assignee in an amount equal to the Commitment or Commitments
assumed by it pursuant to such Assignment and Acceptance and, if the assigning
Lender has retained a Commitment or Commitments hereunder, a new Note or Notes
to the order of the assigning Lender in an amount equal to the Commitment or
Commitments retained by it hereunder.  Such new Note or Notes shall re-evidence
the indebtedness outstanding under the old Notes or Notes and shall be in an
aggregate principal amount equal to the aggregate principal amount of such
surrendered Note or Notes, shall be dated the effective date of such Assignment
and Acceptance and shall otherwise be in substantially the form of the Note or
Notes subject to such assignments.

                 (g)      Each Lender may sell participations (without the
consent of the Administrative Agent, the Issuing Bank, the Borrower or any
other Lender) to one or more parties in or to all or a portion of its rights
and obligations under this Agreement (including, without limitation, all or a
portion of its Commitment, the Loans owing to it and the Note or Notes held by
it and the participations in the ConEd Letter of Credit held by it); provided
that (i) such Lender's obligations under this Agreement (including, without
limitation, its Commitment) shall remain unchanged, (ii) such Lender shall
remain solely responsible to other parties hereto for the performance of such
obligations, (iii) such Lender shall remain the holder of any such Note for all
purposes of this Agreement, (iv) the Borrower, the Administrative Agent, the
Issuing Bank and the other Lenders shall continue to deal solely and directly
with such Lender in connection with such Lender's rights and obligations under
this Agreement and (v) such Lender shall not transfer, grant, assign or sell
any participation under which the participant shall have rights to approve any
amendment or waiver of this Agreement except to the extent such amendment or
waiver would (A) extend the final maturity date or the date for the payments of
any installment of fees or principal or interest of any Loans in which such

                                       98
<PAGE>   106
participant is participating, (B) reduce the amount of any installment of
principal of the Loans in which such participant is participating, (C) reduce
the interest rate applicable to the Loans in which such participant is
participating, (D) reduce any fees payable hereunder, or (E) release all or
substantially all of the Collateral.

                 (h)      Each Lender agrees that, without the prior written
consent of the Borrower and the Administrative Agent, it will not make any
assignment hereunder in any manner or under any circumstances that would
require registration or qualification of, or filings in respect of, any Loan,
Note or other Obligation under the securities laws of the United States of
America or of any state.

                 (i)      Any Lender may at any time assign all or any portion
of its rights under this Agreement and the other Financing Documents to the
Federal Reserve Bank of the United States; provided, that any payment in
respect of such assigned rights made by the Borrower to the assigning Lender in
accordance with the terms of this Agreement shall satisfy the Borrower's
obligations hereunder in respect of such assigned rights to the extent of such
payment.  No such assignment shall release the assignor Lender from its
obligations hereunder.

                 (j)      After the completion of the primary and general
syndication of the Loans described herein, each transferor Lender shall pay the
Administrative Agent a fee of $3,500.00 for processing each assignment made
pursuant to this Section 9.06.

                 Section 9.07     Governing Law; Submission to Jurisdiction;
Waiver of Jury Trial; Waiver of Damages.

                 (a)      THIS AGREEMENT SHALL BE GOVERNED BY AND INTERPRETED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK OTHER THAN ANY SUCH
REQUIREMENT OF LAWS THAT WOULD APPLY THE LAWS OF ANOTHER JURISDICTION, EXCEPT
TO THE EXTENT THAT THE LAWS OF ANOTHER JURISDICTION ARE MANDATORILY APPLICABLE.
ANY DISPUTE ARISING OUT OF, CONNECTED WITH, RELATED TO, OR INCIDENTAL TO THE
RELATIONSHIP ESTABLISHED BETWEEN THE BORROWER AND EACH SECURED PARTY IN
CONNECTION WITH THIS AGREEMENT AND THE OTHER FINANCING DOCUMENTS, AND WHETHER
ARISING IN CONTRACT, TORT, EQUITY OR OTHERWISE, SHALL BE RESOLVED IN ACCORDANCE
WITH THE INTERNAL LAWS (AS OPPOSED TO THE CONFLICTS OF LAWS PROVISIONS) AND
DECISIONS OF THE STATE OF NEW YORK.

                 (b)      EXCEPT AS PROVIDED IN THE NEXT PARAGRAPH, THE
BORROWER AND EACH SECURED PARTY AGREE THAT ALL DISPUTES BETWEEN THEM ARISING
OUT OF, CONNECTED WITH, RELATED TO, OR INCIDENTAL TO THE RELATIONSHIP
ESTABLISHED BETWEEN THEM IN CONNECTION WITH THIS AGREEMENT AND THE OTHER

YORK, NEW YORK, BUT THE BORROWER AND EACH SECURED PARTY ACKNOWLEDGE THAT ANY
APPEALS FROM THOSE COURTS MAY HAVE TO BE HEARD BY A COURT LOCATED OUTSIDE OF
NEW YORK, NEW YORK.  THE BORROWER WAIVES IN ALL DISPUTES ANY

                                       99
<PAGE>   107
OBJECTION THAT IT MAY HAVE TO THE LOCATION OF THE COURT CONSIDERING THE DISPUTE
INCLUDING, WITHOUT LIMITATION, ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON
THE GROUNDS OF FORUM NON CONVENIENS.

                 (c)      THE BORROWER AGREES THAT ANY SECURED PARTY SHALL HAVE
THE RIGHT, TO THE EXTENT PERMITTED BY APPLICABLE REQUIREMENT OF LAW, TO PROCEED
AGAINST THE BORROWER OR ITS PROPERTY IN A COURT IN ANY LOCATION REASONABLY
SELECTED IN GOOD FAITH TO ENABLE ANY SECURED PARTY TO REALIZE ON SUCH PROPERTY,
OR TO ENFORCE A JUDGMENT OR OTHER COURT ORDER ENTERED IN FAVOR OF ANY SECURED
PARTY.  THE BORROWER WAIVES ANY OBJECTION THAT IT MAY HAVE TO THE LOCATION OF
THE COURT IN WHICH ANY SECURED PARTY HAS COMMENCED A PROCEEDING DESCRIBED IN
THIS PARAGRAPH INCLUDING, WITHOUT LIMITATION, ANY OBJECTION TO THE LAYING OF
VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS.

                 (d)      THE BORROWER AND THE SECURED PARTIES EACH WAIVE ANY
RIGHT TO HAVE A JURY PARTICIPATE IN RESOLVING ANY DISPUTE, WHETHER SOUNDING IN
CONTRACT, TORT, OR OTHERWISE ARISING OUT OF, CONNECTED WITH, RELATED TO OR
INCIDENTAL TO THE RELATIONSHIP ESTABLISHED BETWEEN THEM IN CONNECTION WITH THIS
AGREEMENT AND THE OTHER FINANCING DOCUMENTS.  INSTEAD, ANY DISPUTES RESOLVED IN
COURT WILL BE RESOLVED IN A BENCH TRIAL WITHOUT A JURY.

                 (e)      THE BORROWER HEREBY IRREVOCABLY DESIGNATES NATIONAL
REGISTERED AGENTS, INC., WITH AN ADDRESS AT 440 9TH AVENUE, 5TH FLOOR, NEW
YOUR, NEW YORK 10001 AS THE DESIGNEE, APPOINTEE AND AGENT OF THE BORROWER TO
RECEIVE, FOR AND ON BEHALF OF THE BORROWER, SERVICE OF PROCESS IN SUCH
RESPECTIVE JURISDICTIONS IN ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS
AGREEMENT OR THE NOTES, THE OTHER FINANCING DOCUMENTS OR ANY DOCUMENTS RELATED
THERETO.  IT IS UNDERSTOOD THAT A COPY OF SUCH PROCESS SERVED ON SUCH AGENT
WILL BE PROMPTLY FORWARDED BY MAIL TO THE BORROWER AT ITS ADDRESS SET FORTH IN
ANNEX II HERETO IN ACCORDANCE WITH SECTION 9.01.  THE BORROWER FURTHER
IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OF ANY OF THE AFOREMENTIONED
COURTS IN ANY SUCH ACTION OR PROCEEDING BY THE MAILING OF COPIES THEREOF BY
REGISTERED OR CERTIFIED MAIL, POSTAGE PREPAID, TO THE BORROWER AT ITS SAID
ADDRESS, SUCH SERVICE TO BECOME EFFECTIVE ON THE DATE OF RECEIPT THEREOF.

                 (f)      NOTHING HEREIN SHALL AFFECT THE RIGHT OF ANY PARTY
HERETO OR ANY HOLDER OF A NOTE TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED
BY LAW OR TO COMMENCE LEGAL PROCEEDINGS OR OTHERWISE PROCEED AGAINST ANY PARTY
IN ANY OTHER JURISDICTION.

                 Section 9.08     Nonliability of Administrative Agent and
Lenders.  The relationship between the Borrower and the Secured Parties shall
be solely that of borrower and

                                      100
<PAGE>   108
lender.  No Secured Party shall have any fiduciary responsibilities to the
Borrower. No Secured Party undertakes any responsibility to the Borrower to
review or inform the Borrower of any matter in connection with any phase of the
Borrower's business or operations.

                 Section 9.09     Marshalling; Recapture. No Secured Party
shall be under any obligation to marshal any assets in favor of the Borrower or
any other party or against or in payment of any or all of the Obligations.  To
the extent any Secured Party receives any payment by or on behalf of the
Borrower, which payment or any part thereof is subsequently invalidated,
declared to be fraudulent or preferential, set aside or required to be repaid
to the Borrower or its estate, trustee, receiver, custodian or any other party
under any bankruptcy law, state or federal law, common law or equitable cause,
then to the extent of such payment or repayment, the obligation or part thereof
which has been paid, reduced or satisfied by the amount so repaid shall be
reinstated by the amount so repaid and shall be included within the liabilities
of the Borrower to such Secured Party as of the date such initial payment,
reduction or satisfaction occurred.

                 Section 9.10     Independent Nature of Lenders' Rights.  The
amounts payable at any time hereunder to each Lender shall be a separate and
independent debt, and, except as otherwise provided in any Financing Document,
each Lender shall be entitled to protect and enforce its rights arising our of
this Agreement, and it shall not be necessary for any other Lender to be joined
as an additional party in any proceeding for such purpose.

                 Section 9.11     Counterparts.  This Agreement may be executed
in any number of counterparts and by the different parties hereto in separate
counterparts, each of which when so executed and delivered shall be an
original, but all of which shall together constitute one and the same
instrument.

                 Section 9.12     Effectiveness.  This Agreement shall become
effective on the date on which all of the parties hereto shall have signed a
copy hereof (whether the same or different copies) and shall have delivered the
same to the Administrative Agent pursuant to Section 9.01 or, in the case of
the Lenders, shall have given to the Administrative Agent written, telecopied
or telex notice (actually received) at such office that the same has been
signed and mailed to it.

                 Section 9.13     Survival of Indemnities and Representations
and Warranties.  All indemnities set forth herein and all representations and
warranties made herein and in any document, certificate or statement delivered
pursuant hereto or in connection herewith shall survive the execution and
delivery of this Agreement, the Notes, the ConEd Letter of Credit and the other
Financing Documents and the making and repayment of the Loans and the
expiration or cancellation of the ConEd Letter of Credit.

                 Section 9.14     Severability.  In case any provision in or
obligation under this Agreement or the Notes or the other Financing Documents
shall be invalid, illegal or unenforceable in any jurisdiction, the validity,
legality and enforceability of the remaining provisions or obligations, or of
such provision or obligation in any other jurisdiction, shall not in any way be
affected or impaired thereby.

                 Section 9.15     Headings Descriptive.  The headings of the
several sections and subsections of this Agreement, and the Table of Contents,
are inserted for convenience only and shall not in any way affect the meaning
or construction of any provision of this Agreement.

                 Section 9.16     Limitation of Recourse.  The obligations of
the Borrower hereunder and under the other Financing Documents are obligations
solely of the Borrower and shall not constitute a debt or obligation of any
direct or indirect partner or shareholder of the Borrower or any of their
respective directors, officers, agents or employees (each such Person, a
"Non-Recourse Party").  No Non-Recourse Party shall be liable for any amount
payable by the Borrower under this Agreement or the other Financing Documents,
and the Secured Parties shall not seek a money judgment or deficiency or
personal judgment against any Non-Recourse Party for payment of the
indebtedness payable by the Borrower evidenced by this Agreement or the other
Financing Documents.  No property or assets of any Non-Recourse Party, other
than as contemplated in the Financing Documents, shall be sold, levied upon or
otherwise used to satisfy any judgment rendered in connection with any action
brought against the Borrower with respect to this Agreement or the other
Financing Documents.  The foregoing acknowledgments, agreements and waivers
shall be enforceable by any Non-Recourse Party.  Notwithstanding the foregoing,
nothing in this Section shall limit or affect or be construed to limit or
affect the obligations and liabilities of any Credit Party or any other
Non-Recourse Party (a) in accordance with the terms of any Transaction Document
or Financing Document creating such liabilities and obligations to which such
Credit Party or Non-Recourse Party is a party, (b) arising from liability
pursuant to applicable Requirements of Law for such Credit Party's or such
Non-Recourse Party's fraudulent actions, knowing misrepresentations or willful
misconduct or (c) with respect to amounts distributed to it in violation of
Section 6.10 hereof.

the right, title and interest of such Borrower Entity which it now possesses or

Permitted Investments and other securities and instruments held in such Accounts
and Sub-Accounts, and all other funds held by the Administrative Agent under

Collateral, shall be subject to the terms and conditions of this Agreement and
the other Financing Documents.

       (b)    Each Borrower Entity agrees that it will not take any actions or
fail to perform any of its duties or obligations under this Agreement so that
after giving effect to such action or inaction the Administrative Agent will not
then, or with the passage of time, cease to have a perfected first priority
security interest in any of the Account Collateral.

       (c)    Each Borrower Entity agrees that from time to time, at the expense
of such Borrower Entity, such Borrower Entity will promptly execute and deliver

granted hereby or to enable the Administrative Agent to exercise and enforce its
rights and remedies hereunder with respect to any Account Collateral. Without
limiting the generality of the foregoing, each Borrower Entity will execute and
file, with a copy thereof to the Administrative Agent, such financing or
continuation statements, or amendments thereto, and such other instruments or
notices, as may be necessary, or as the Administrative Agent may reasonably
request, in order to perfect and preserve the pledge, assignment and security
interest granted or purported to be granted hereby.

any security agreement or financing statement covering the Account Collateral or
any part thereof shall be sufficient as a financing statement where permitted by
law.

       (e)    Each Borrower Entity will furnish to the Administrative Agent from
time to time statements and schedules further identifying and describing the
Account Collateral and such other reports in connection with the Account
Collateral as the Administrative Agent may reasonably request, all in reasonable
detail.

Account, to indicate by book entry that such Account Collateral has been
credited to and is carried in the applicable Account and accept such Account
Collateral for credit to the applicable Account.

permit any of its creditors to obtain control over any Account or the Borrower's
interest in any financial asset credited thereto or carried therein, or (ii)

relating to any of the Accounts and the financial assets credited or to be

       Section 6.1   Investments. Each Borrower Subsidiary hereby authorizes the
Borrower to elect Permitted Investments for the funds on deposit from time to
time in such Borrower Subsidiary's Sub-Accounts. Prior to the occurrence of any

the risk and expense of the relevant Borrower Entity, solely in such Permitted
Investments as the Borrower, shall direct (or, so long as any Default or Event

may in its discretion select). The Borrower shall select Permitted Investments
having such maturities as shall cause each Account to have a cash balance as of
any day sufficient to cover the transfers to be made from such Account on such
day in accordance with this Agreement. In the event that the cash balance in any
Account is as of any day insufficient to cover the transfers to be made from
such Account on such day, the Administrative Agent may (but shall not be
obligated to) sell or liquidate the Permitted Investments held in such Account
(without regard to maturity date) in such manner as the Administrative Agent may
reasonably deem necessary in order to obtain cash at least sufficient to make
such transfers and to pay any expenses and charges incurred in connection with
effecting any such sale or liquidation, which expenses and charges the
Administrative Agent shall be authorized to pay with cash on deposit in such
Account. The Administrative Agent shall not be liable to any Person for any loss
suffered because of any such sale or liquidation other than by reason of its
willful misconduct or gross negligence.

       Section 6.2   Income or Gain. Any interest, investment income or gain
realized as a result of any Permitted Investments held in the Accounts (net of
the expenses incurred in connection with making such Permitted Investments)

<PAGE>   156

Account on the last Business day of each month and applied or reinvested as
provided herein. The Administrative Agent shall have no liability for any loss
resulting from any such Permitted Investment other than by reason of its willful
misconduct or gross negligence.

the Accounts shall be valued by the Administrative Agent, as the case may be, as
follows:

       (a)    cash shall be valued at the face amount thereof, and

       (b)    securities shall be valued at market value thereof.

       Section 6.4   Taxes. It is acknowledged by the parties hereto that all
interest and other investment income earned on amounts on deposit in the

the Borrower. The Borrower shall be responsible for determining any requirements
for paying taxes or reporting or withholding any payments for tax purposes
hereunder. The Borrower shall prepare and file all tax information required with
respect to the Accounts and without limiting Section 2.12 of the Credit
Agreement, the Borrower agrees to indemnify and hold the Administrative Agent
harmless against all liability for tax withholding and/or reporting for any
payments. Such indemnities shall survive the termination or discharge of this
Agreement or resignation of the Administrative Agent. The Administrative Agent
shall not have any obligation with respect to the making of or the reporting of
any payments for tax purposes other than to the extent it is provided with
monies and/or the reports in respect thereof.

                        APPLICATION OF INSURANCE PROCEEDS

       Section 7.1   Insurance Failure. So long as the Credit Agreement is in
effect and any Lender shall have any Commitment outstanding thereunder, and
until the Notes, together with interest and all other Obligations are
indefeasibly paid in full and the ConEd Letter of Credit has been terminated:

       (a)    In the case of damage to any portion of the Portfolio Assets for
which any Borrower Entity receives, or has the right to receive, Insurance
Proceeds in an amount up to $5,000,000 per occurrence or, in respect of all
Borrower Entities, $10,000,000 in the aggregate, which shall have previously
been deposited in the Insurance Proceeds Account, the Borrower may elect to use
such Insurance Proceeds for the reinstatement, reconstruction, repair or
replacement of the damaged Portfolio Asset(s). The Borrower shall notify the
Administrative Agent of such election, and the Administrative Agent, when
available for disbursement, shall disburse the requested amount from the
Insurance Proceeds Account pursuant to Section 5.8(a) hereof. In the event that
the Borrower shall elect not to apply the Insurance Proceeds to the
reinstatement, reconstruction, repair or replacement of the damaged Portfolio
Asset(s), the Administrative Agent shall withdraw the available Insurance
Proceeds from the Insurance Proceeds Account and deposit such amount into the
Prepayment Account in accordance with Section 5.8(c).

which any Borrower Entity receives, or has the right to receive, Insurance
Proceeds in an amount in excess of $5,000,000 per occurrence or, in respect of
all Borrower Entities, $10,000,000 in the aggregate, but less than $15,000,000
in the aggregate in all instances, which shall have previously been deposited in
the Insurance Proceeds Account, the Borrower shall deliver to the Administrative
Agent within 45 days after any Borrower Entity shall have obtained actual
knowledge of such damage:

              (i)    a breakdown of the nature and extent of damage incurred in
       reasonable detail;

              (ii)   a bona fide assessment from a contractor reasonably
       acceptable to the Administrative Agent, (after consultation with the
       Independent Engineer) estimating the costs and time frame necessary to
       repair the damaged or affected portion of the Portfolio Assets in order
       for such portion to operate at, or to be capable of operating at,
       substantially the same level at which it operated prior to the loss;

              (iii)  a demonstration to the reasonable satisfaction of the
       Administrative Agent (after consultation with the Independent Engineer)
       that the Borrower has sufficient funds (from the proceeds of insurance
       and any other sources) to pay for the proposed reconstruction, repair or
       replacement;

              (iv)   evidence that none of the existing Project Contracts has
       been terminated as a result of such damage (other than those which have
       been, or are being, diligently replaced by other acceptable agreements in
       accordance with the requirements set forth in the Credit Agreement)
       during such reconstruction, repair or replacement (except for those
       Project Contracts (A) which have expired pursuant to their terms or are
       otherwise not intended to be in effect at such time and (B) whose
       termination would not reasonably be expected to result in a Material
       Adverse Effect taking into account any available sources of funds to the
       Borrower Entities (including business interruption insurance) and efforts
       to replace such Project Contract); provided, that all applicable
       Insurance Policies remain in full force and effect; and

              (v)    a demonstration to the reasonable satisfaction of the
       Administrative Agent, that at the completion of such reconstruction,
       repair or replacement no Default or Event of Default would reasonably be
       expected to occur or exist.

       The Administrative Agent may request confirmation or reports from the
Independent Engineer with respect to the information provided by the Borrower
pursuant to clauses (i), (ii) and (iii) above. The Administrative Agent, acting
at the direction of the Required Lenders in accordance with this Section 7.1,
will have the right to withhold its consent to any such proposed reconstruction,
repair or replacement, if the Borrower fails to satisfy any of the clauses (i)
through (v) above. In the event that such consent is withheld, the
Administrative Agent shall notify the Borrower as to the basis for withholding
such consent. The Borrower shall be entitled, within thirty (30) days after
receipt of such notification to make a one-time resubmission of the information
and documentation required by the Section 7.1(b). If the Administrative Agent
shall

                                       29
<PAGE>   158

be directed by the Required Lenders in accordance with this Section 7.1 to
withhold consent to the resubmitted request, the Administrative Agent shall
apply such Insurance Proceeds in accordance with Section 2.07 of the Credit
Agreement.

       In the event the Borrower receives the above-mentioned consent of the
Administrative Agent, the Borrower shall have the right to provide written
notice(s) to direct the Administrative Agent to transfer such Insurance Proceeds
in accordance with such written notice(s). The Borrower agrees to apply such
Insurance Proceeds as described above and to proceed diligently and in good
faith with the reinstatement, reconstruction, repair or replacement, as the case
may be, of the damaged part of the Portfolio Assets, and the Independent
Engineer, on behalf of the Lenders, will have the right to observe and inspect
such reconstruction, repair or replacement.

       (c)    If (i) the damage to the Portfolio Assets is in excess of
$15,000,000 in the aggregate, (ii) the Borrower gives notice that it will not
reinstate, reconstruct, repair or replace the damaged Portfolio Assets, (iii)
the Borrower fails to obtain the consent of the Administrative Agent in
accordance with paragraph (b) above within 45 days of such damage (as such
period may be extended pursuant to the penultimate paragraph of this Section
7.1(b), (iv) after receiving such consent, the Borrower does not proceed to
reinstate, reconstruct, repair or replace the damaged Portfolio Assets with
diligence and in accordance with the Project Contracts, the Financing Documents
and applicable Requirements of Law or (v) the Borrower terminates such
reinstatement, reconstruction, repair or replacement, the Administrative Agent
shall, unless otherwise directed by the Required Lenders, withdraw the Insurance
Proceeds then on deposit in the Insurance Proceeds Account in respect of such
damaged Portfolio Assets and deposit such amount into the Prepayment Account in
accordance with Section 5.8(c).

in this respect, and such confirmation shall be binding upon the Administrative
Agent and the other Secured Parties.

willful misconduct) or (ii) without limiting Section 2.12 of the Credit
Agreement any refund or adjustment of any amount paid or payable to the

exercising any rights under any of the Assigned Agreements which shall be
inconsistent with the exercise of the rights and functions herein granted to the
Administrative Agent as the attorney-in-fact, including abstaining from
collecting, claiming and receiving any monies under the Assigned Agreements,
provided, that, nothing herein shall prevent the Borrower from, except during
the exercise by the Administrative Agent of any such rights and functions,

reimburse the Administrative Agent and/or its agents, representatives,
successors and assignees as the case may be, for any monies paid by it with
interest thereon at the Default Rate from the date the same shall have been paid
by the Administrative Agent and/or its agents, representatives, successors and
assigns until actually paid by the Borrower to the extent that there are then
insufficient funds available in the Revenue Account for this purpose.

(or similar statement or instrument of registration under the law of any
jurisdiction) covering or purporting to cover any interest of any kind in the
Assignment Revenues or the Assignment Collateral and so long as any of the
Secured Obligations remain unpaid or any Commitments remain outstanding, the
Borrower will not execute or authorize to be filed in any public office any
financing statement (or similar statement or instrument of registration under

RIGHTS; INSTRUMENTS.

              4.01   Additional Representations and Warranties: As of the time
when each Receivable and General Intangible arises, the Borrower shall be deemed
to have represented and warranted, to the knowledge of the Borrower and unless
otherwise promptly disclosed by the Borrower in writing to the Administrative
Agent upon the Borrower obtaining actual knowledge thereof, that such Receivable
or General Intangible, as the case may be, and all records, papers and documents
relating thereto (if any) are genuine and in all respects what they purport to
be, and that all records, papers and documents (if any) relating thereto (i)
will represent the genuine, legal, valid and binding obligation of the account
debtor evidencing indebtedness unpaid and owed by the respective account debtor
arising out of the performance of labor or services or the sale or lease and
delivery of electricity or capacity, or any other merchandise listed therein, or
both, and (ii) are in compliance and will conform with all Requirements of Law.

              4.02   Maintenance of Records. The Borrower will keep and maintain
at its own cost and expense records consistent with GAAP of the Assigned
Agreements and the Receivables, including, but not limited to, the originals of
all documentation (including each Assigned Agreement) with respect thereto,
records of all payments received, all credits granted thereon (but subject to
customary record retention policies) and all other dealings therewith. The

                                       13
<PAGE>   198

Borrower will make the same available to the Administrative Agent for inspection
pursuant to Section 5.08 of the Credit Agreement.

              4.03   Payments Under Assigned Agreements, Receivables and General
Intangibles.  (a) Non-Payment to the Administrative Agent. If the Borrower shall
receive payment directly from any party to an Assigned Agreement (including any
letter of credit issued for the benefit of the Borrower in accordance with the
terms thereof) or from any account debtor or other obligor under any Receivable,
General Intangible or any other payments under such Assigned Agreements,
Receivables and General Intangibles, the Borrower shall receive such payments in
a constructive trust for the benefit of the Lenders, shall segregate such
payments from such party's other funds, and shall forthwith transmit and deliver
such payments to the Administrative Agent in the same form as so received (with
any necessary endorsement).

              (b)    Application of Funds. All amounts received by the
Administrative Agent pursuant to this Section 4.03 or Section 4.04 shall be
deposited into the Revenue Account and applied as set forth in the Deposit
Account Agreement.

              4.04   Direction to Account Debtors; Contracting Parties; etc. The
Borrower agrees that the Administrative Agent may, upon reasonable notice to
Borrower of its failure to do so directly notify the obligors with respect to
any Receivables, General Intangibles and/or under any Assigned Agreements to
make payments with respect thereto as provided in Sections 2.01(c) (ii) and
4.03. Upon the occurrence and during the continuance of any Event of Default,
the Administrative Agent may apply, without notice to or assent by the Borrower,
any or all amounts then in, or thereafter deposited in, the Accounts in the
manner provided in the Deposit Account Agreement. The reasonable costs and
expenses (including reasonable attorneys' fees) of collection, whether incurred
by the Borrower or the Administrative Agent, shall be borne by the Borrower.

              4.05   Modification of Terms, etc. Except as otherwise provided in
the Credit Agreement or as permitted in Section 4.06 hereof, (a) the Borrower
shall not rescind or cancel any Indebtedness in any fiscal year in an amount, in
the aggregate, in excess of $100,000 evidenced by any Receivables, General
Intangibles or Assigned Agreements, or modify in any manner adverse to the
Borrower or the Secured Parties any material term thereof, or make any
adjustment adverse to the Borrower or the Secured Parties with respect thereto,
or grant any extension for performance of the same, or compromise or settle any
dispute, claim, suit or legal proceeding relating thereto, or sell any
Receivable, General Intangible or Assigned Agreements, or interest therein,
without the prior written consent of the Administrative Agent, which consent the
Administrative Agent will not unreasonably withhold, delay or condition, and (b)
the Borrower will duly fulfill all material obligations on its part to be
fulfilled under or in connection with the Receivables, the General Intangibles
and the Assigned Agreements and will do nothing to impair the security interests
of the Administrative Agent (including, without limitation, the creation,
attachment and priority thereof) in the Receivables, the General Intangibles or
the Assigned Agreements.

                                       14
<PAGE>   199

              4.06   Collection. The Borrower shall endeavor to cause to be
collected from the account debtor named in the Borrower's Receivables and
General Intangibles or obligor under any Assigned Agreements, and paid by such
account debtor directly to the Revenue Account, as and when due (including,
without limitation, amounts which are delinquent, such amounts to be collected
in accordance with generally accepted lawful collection procedures) any and all
amounts owing under or on account of such Receivable, General Intangible or
Assigned Agreements, and apply forthwith upon receipt thereof all such amounts
as are so collected to the outstanding balance of such Receivable, General
Intangible or under such Assigned Agreements, except that, unless an Event of
Default shall have occurred and be continuing (and shall not have been waived by
an appropriate vote or other action by the Required Lenders), the Borrower may
allow in the ordinary course of business as adjustments to amounts owing under
the Borrower's Receivables, General Intangibles and Assigned Agreements an
extension or renewal of the time or times of payment, or settlement for less
than the total unpaid balance, which the Borrower finds appropriate to enhance
collectibility in accordance with sound business judgment. The reasonable costs
and expenses (including, without limitation, reasonable attorneys fees) of
collection, whether incurred by the Borrower or the Administrative Agent, shall
be borne by the Borrower.

              SECTION 5. SPECIAL PROVISIONS CONCERNING PATENTS, COPYRIGHTS AND
TRADEMARKS.

              5.01   Infringements. Promptly upon obtaining actual knowledge
thereof, the Borrower shall notify the Administrative Agent and the Lenders in
writing of all pertinent details available to it, with respect to any
infringement or other violation of the Borrower's rights in, or any claim of any
such infringement of, any, Patent, Copyright or Trademark, whether or not such
right is presently held by the Borrower or third party. As to each such
instance, absent the Required Lenders' authorization to proceed otherwise, which
authorization shall not be unreasonably withheld, delayed or conditioned, and to
the extent permitted by applicable Requirements of Law, the Borrower shall use
commercially reasonable efforts to pursue a remedy.

              5.02   Other Patents, Copyrights and Trademarks. If the Borrower
hereafter acquires rights in any Patent, Copyright or Trademark, the Borrower
shall deliver to the Administrative Agent and the Lenders within 30 days, a copy
of such Patent, Copyright or Trademark and a first priority perfected security
interest therein or a collateral assignment thereof, as appropriate.

              5.03   Remedies. If an Event of Default shall occur and be
continuing (and shall not have been waived by an appropriate vote or other
action by the Lenders), the Administrative Agent, acting pursuant to and in
accordance with the terms of the Deposit Account Agreement, the other Financing
Documents and applicable Requirements of Law may (a) declare the entire right,
title, and interest of the Borrower in any Patents, Copyrights and Trademarks
vested in the Administrative Agent, in which event such right, title, and
interest immediately shall vest in the Administrative Agent; and (b) take and
practice or use or sell any or all of such Patents, Copyrights or Trademarks, or
take and use or sell the Borrower's rights in such Patents,

                                       15
<PAGE>   200

Copyrights or Trademarks, along with the goodwill and all other elements of the
Borrower's ongoing business symbolized by such assets and secured under this
Agreement, and the right to carry on the business of the Borrower in connection
with which such assets have been used. The Borrower shall execute any other and
further documents which the Administrative Agent may request further to confirm
the foregoing and to transfer to the Administrative Agent ownership of the
Borrower's rights to such Trademarks, Patents and/or Copyrights.

              SECTION 6. PROVISIONS CONCERNING ALL ASSIGNMENT REVENUES AND
ASSIGNMENT COLLATERAL; INSURANCE.

              6.01   Protection of the Administrative Agent's Interests. The
Borrower will do nothing to impair the rights of the Administrative Agent or the
Lenders in the Assignment Revenues and the Assignment Collateral, provided,
however, that nothing herein shall prevent the Borrower, prior to the exercise
by the Administrative Agent of any such rights, from undertaking the Borrower's
operations in the ordinary course of business in accordance with the Assigned
Agreements. The Borrower assumes all liability and responsibility in connection
with the Assignment Revenues and the Assignment Collateral and the liability of
the Borrower with respect to the Secured Obligations shall in no way be affected
or diminished by reason of the fact that such Assignment Revenues and Assignment
Collateral may be lost, destroyed, stolen, damaged or for any reason whatsoever
unavailable to the Borrower.

              6.02   Further Actions. The Borrower will, at its own expense,
make, execute, endorse, acknowledge, file and/or deliver to the Administrative
Agent and the Lenders from time to time such lists, descriptions and
designations of the Assignment Revenues and the Assignment Collateral, warehouse
receipts, receipts in the nature of warehouse receipts, bills of lading,
documents of title, vouchers, invoices, schedules, confirmatory assignments,
conveyances, financing statements, transfer endorsements, powers of attorney,
certificates, reports and other assurances or instruments and take such further
steps relating to the Assignment Revenues and the Assignment Collateral and
other property or rights covered by the interests hereby granted, which is
necessary to perfect, preserve or protect its ownership and security interests
in the Assignment Revenues and the Assignment Collateral or is otherwise
reasonably requested by the Administrative Agent; provided, that the foregoing
shall not require the Borrower to obtain any Additional Contract Consent except
as expressly required by Section 5.24 of the Credit Agreement.

              6.03   Financing Statements. The Borrower agrees to assign and
deliver to the Administrative Agent, on behalf of the Lenders, such financing
statements (or similar statement or instrument of registration under the law of
any jurisdiction), in form reasonably acceptable to the Administrative Agent as
it may from time to time reasonably request or as are necessary or desirable in
their reasonable opinion to establish and maintain the security interests
contemplated hereunder as valid, enforceable, first priority security interests
as provided herein and the other rights and security contemplated herein, all in
accordance with the Uniform Commercial Code as enacted in any and all relevant
jurisdictions or any other Requirement of Law. The Borrower will pay any
applicable filing fees and related expenses. The Borrower authorizes the

                                       16
<PAGE>   201

Administrative Agent to file any such financing statements without the signature
of the Borrower to the extent permitted under applicable Requirements of Law.

              SECTION 7. REMEDIES UPON OCCURRENCE OF EVENT OF DEFAULT.

              7.01   Remedies; Obtaining the Assignment Collateral Upon Default.
The Borrower agrees that, if any Event of Default shall have occurred and be
continuing (and shall not have been waived by an appropriate vote or other
action by the Required Lenders), then and in every such case, subject to the
terms and provisions of the Credit Agreement and any Requirement of Law then in
effect, the Administrative Agent, in addition to any rights now or hereafter
existing under any Requirement of Law, shall have all rights as a secured
creditor under the Uniform Commercial Code or any other Requirement of Law in
all relevant jurisdictions and may, acting pursuant to and in accordance with
the terms of the Credit Agreement:

              (a)    personally, or by agents or attorneys, immediately retake
       possession of the Assignment Collateral or any part thereof, from the
       Borrower or any other Person who then has possession of any part thereof
       with or without notice or process of law, and for that purpose may enter
       upon the Borrower's premises where any of the Assignment Collateral is
       located and remove the same and use in connection with such removal any
       and all services, supplies, aids and other facilities of the Borrower;
       and

              (b)    instruct the obligor or obligors on any agreement,
       instrument or other obligation (including, without limitation, any other
       Assigned Agreement, the General Intangibles and the Receivables)
       constituting the Assignment Revenues and Assignment Collateral to make
       any payment required by the terms of such instrument or agreement
       directly to the Administrative Agent for deposit in the Revenue Account
       (or any other account required or contemplated by the Deposit Account
       Agreement) and application pursuant to the Deposit Account Agreement; and

              (c)    apply all monies, securities and instruments in the Revenue
       Account, and each other Account, in accordance with the Deposit Account
       Agreement; and

              (d)    sell, assign or otherwise liquidate, or direct the Borrower
       to sell, assign or otherwise liquidate, any or all of the Assignment
       Collateral or any part thereof, and take possession of the proceeds of
       any such sale or liquidation for deposit in the Revenue Account (or any
       other account required or contemplated by the Deposit Account Agreement)
       and application pursuant to the Deposit Account Agreement; and

              (e)    take possession of the Assignment Collateral or any part
       thereof, by directing the Borrower in writing to deliver the same to the
       Administrative Agent at any place or places designated by the
       Administrative Agent, in which event the Borrower shall at its own
       expense:

                     (i)   forthwith cause the same to be moved to the place or
              places so designated by the Administrative Agent and there
              delivered to the Administrative Agent,

                                       17
<PAGE>   202

                     (ii)  store and keep any Assignment Collateral so delivered
              to the Administrative Agent (to the extent not physically
              delivered to the Administrative Agent) at such place or places
              pending further action by the Administrative Agent as provided in
              Section 7.02, and

                     (iii) while such Assignment Collateral shall be so stored
              and kept, provide such guards and maintenance services as shall be
              necessary to protect the same and to preserve and maintain them in
              good condition;

   it being understood that the Borrower's obligation to so deliver the
   Assignment Collateral is of the essence of this Agreement and that,
   accordingly, upon application to a court of equity having jurisdiction, the
   Administrative Agent shall be entitled to a decree requiring specific
   performance by the Borrower of such obligation.

              7.02   Remedies, Disposition of the Assignment Collateral. Any
Assignment Collateral repossessed by the Administrative Agent under or pursuant
to Section 7.01, and any other Assignment Collateral whether or not so
repossessed by the Administrative Agent, may be sold, assigned, leased or
otherwise disposed of under one or more contracts or as an entirety, and without
the necessity of gathering at the place of sale the property to be sold, and in
general in such manner, at such time or times, at such place or places and on
such terms as the Administrative Agent, acting in good faith, may, upon written
direction in compliance with any Requirement of Law, determine to be
commercially reasonable. Subject to the foregoing, any of the Assignment
Collateral may be sold, leased or otherwise disposed of, in the condition in
which the same existed when taken by the Administrative Agent or after any
overhaul or repair which the Administrative Agent, acting in good faith, shall
determine to be commercially reasonable. Any such disposition which shall be a
private sale or other private proceeding permitted by such requirements shall be
made upon not less than 10 days' written notice to the Borrower specifying the
time at which such disposition is to be made and the intended sale price or
other consideration therefor, and shall be subject, for the 10 days after the
giving of such notice, to the right of the Borrower or any nominee of the
Borrower to acquire the Assignment Collateral involved at a price or for such
other consideration at least equal to the intended sale price or other
consideration so specified. To the extent permitted by Requirements of Law, the
Administrative Agent on behalf of the Lenders may bid for and become the
purchaser of the Assignment Collateral or any item thereof, offered for sale in
accordance with this Section 7.02. If, under mandatory requirements of any
Requirement of Law, the Administrative Agent shall be required to make
disposition of the Assignment Collateral within a period of time which does not
permit the giving of notice to the Borrower as hereinabove specified, the
Administrative Agent need give the Borrower only such notice of disposition as
shall be reasonably practicable in view of such mandatory requirements of any
Requirement of Law.

              The Borrower hereby irrevocably appoints the Administrative Agent
as its attorney-in-fact, so that the Administrative Agent, or any Person
empowered by the Administrative Agent, shall be authorized to sell, assign,
lease or otherwise dispose of the Assignment Collateral or any part thereof
pursuant to the provisions of the preceding paragraph, and, in general, to do or
cause to be done all such acts and things which are otherwise required to be
done by the Borrower under this Agreement.

                                       18
<PAGE>   203

              7.03   Waiver of Claims. Except as otherwise provided in this
Agreement or in any other Financing Document, THE BORROWER HEREBY WAIVES, TO THE
EXTENT PERMITTED BY APPLICABLE LAW, NOTICE AND JUDICIAL HEARING IN CONNECTION
WITH THE ADMINISTRATIVE AGENT TAKING POSSESSION OR THE ADMINISTRATIVE AGENT'S
DISPOSITION OF ANY OF THE ASSIGNMENT COLLATERAL, IN EACH CASE AS PERMITTED BY
APPLICABLE REQUIREMENTS OF LAW, INCLUDING, WITHOUT LIMITATION, ANY AND ALL PRIOR
NOTICE AND HEARING FOR ANY PREJUDGMENT REMEDY OR REMEDIES AND ANY SUCH RIGHT
WHICH THE BORROWER WOULD OTHERWISE HAVE UNDER THE CONSTITUTION OR ANY STATUTE OF
THE UNITED STATES OR ANY POLITICAL SUBDIVISION OF ANY SUCH JURISDICTION, and the
Borrower hereby further waives, to the extent permitted by Requirements of Law:

              (i)    all damages occasioned by such taking of possession except
       any damages which are the direct result of the gross negligence or
       willful misconduct of the Administrative Agent, any Lender, or any Person
       acting on its behalf or instruction;

              (ii)   all other requirements as to the time, place and terms of
       sale or other requirements with respect to the enforcement of the
       Administrative Agent's rights hereunder; and

              (iii)  all rights of redemption, appraisement, valuation, stay,
       extension or moratorium now or hereafter in force under any Requirements
       of Law in order to prevent or delay the enforcement of this Agreement
       (including, without limitation, any right to claim that such enforcement
       should be stayed pending the outcome of any other action or proceeding
       (including any arbitration proceeding)) or the absolute sale of the
       Assignment Collateral or any portion thereof, and the Borrower, for
       itself and all who may claim under it, insofar as it or they now or
       hereafter lawfully may, hereby waives the benefit of all such
       Requirements of Law.

To the extent permitted under Requirements of Law, any sale of, or the grant of
options to purchase, or any other realization upon, any Assignment Collateral
shall operate to divest all right, title, interest, claim and demand, either at
law or in equity, of the Borrower therein and thereto, and shall be a perpetual
bar both at law and in equity against the Borrower and against any and all
Persons claiming or attempting to claim the Assignment Collateral so sold,
optioned or realized upon, or any part thereof, from, through and under the
Borrower.

              7.04   Application of Proceeds. The Proceeds of any Assignment
Collateral obtained or disposed of pursuant to this Agreement, including
Sections 7.01 and 7.02 shall be applied in accordance with the Deposit Account
Agreement.

For the avoidance of doubt, it is understood that the Borrower shall remain
liable to the extent of any deficiency between the amount of the Proceeds of the
Assignment Collateral and the aggregate amount of the Secured Obligations.

                                       19
<PAGE>   204

              7.05   Remedies Cumulative. No failure or delay on the part of the
Administrative Agent or any Lender in exercising any right, power or privilege
hereunder or under any other Financing Document and no course of dealing between
the Borrower and the Administrative Agent or any Lender shall operate as a
waiver thereof; nor shall any single or partial exercise of any right, power or
privilege hereunder or under any other Financing Document preclude any other or
further exercise thereof or the exercise of any other right, power or privilege
hereunder or thereunder. The rights, powers and remedies herein or in any other
Financing Document expressly provided are cumulative and not exclusive of any
rights, powers or remedies which the Administrative Agent or any Lender would
otherwise have. No notice to or demand on the Borrower in any case shall entitle
the Borrower to any other or further notice or demand in similar or other
circumstances or constitute a waiver of the rights of the Administrative Agent
or any Lender to any other or further action in any circumstances without notice
or demand.

              7.06   Discontinuance of Proceedings. In case the Administrative
Agent shall have instituted any proceeding to enforce any right, power or remedy
under this Agreement by foreclosure, sale, entry or otherwise, and such
proceeding shall have been discontinued or abandoned for any reason or shall
have been determined adversely to the Administrative Agent, then and in every
such case the Borrower, the Administrative Agent and each holder of any of the
Obligations shall be restored to their former positions and rights hereunder
with respect to the Assignment Collateral subject to the security interest
created under this Agreement, and all rights, remedies and powers of the
Administrative Agent shall continue as if no such proceeding had been
instituted.

              7.07   Grant of License or Sub-License to Use Patent, Trademark,
Copyright and License Collateral. For the purpose of enabling the Administrative
Agent to exercise rights and remedies under this Article VII at such time as the
Administrative Agent shall be lawfully entitled to exercise such rights and
remedies, the Borrower hereby grants to Administrative Agent an irrevocable,

<PAGE>   220

              NOW, THEREFORE, in consideration of the foregoing premises and for
other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, the parties hereto agree as follows:

              1. Definitions: Construction. (a) For the purposes of this
Agreement, (i) capitalized terms not otherwise defined herein shall have the
meanings set forth in Article I of the Credit Agreement, and (ii) the principles
of the construction set forth in such Article I shall apply hereto.

              (b)    In addition, wherever used in this Agreement and unless the
context otherwise requires, the following terms shall have the following
meanings:

              "AGREEMENT" shall mean this Stock Pledge Agreement.

              "COMPANIES" shall mean the collective reference to the LP Company
and the GP Company.

              "GP COMPANY" shall have the meaning provided in the first recital
to this Agreement.

              "GP PLEDGED SHARES" shall have the meaning provided in the first
recital to this Agreement.

              "LP COMPANY" shall have the meaning provided in the first recital
to this Agreement.

              "PLEDGED COLLATERAL" shall have the meaning specified in Section
3.1.

              "PLEDGED SHARES" shall mean the collective reference to the LP
Pledged Shares and the GP Pledged Shares.

              "SECURED OBLIGATIONS" shall have the meaning provided in Section

              2.     Security. (a) This Agreement is for the benefit of the
Administrative Agent and the other Secured Parties to secure (i) the prompt and
complete payment and performance when due by the Borrower of all of the
Obligations, including, without limitation, all amounts payable or to become
payable to the Secured Parties by the Borrower under the Financing Documents
when and as the same shall become due and payable (whether by acceleration or
otherwise) in accordance with the terms thereof, and (ii) the due performance
and compliance by the Pledgor with the terms hereof and each other Financing
Document to which it is a party (collectively, the "Secured Obligations").
Without limiting the generality of the foregoing, this Agreement secures the
payment of all amounts which constitute part of the Secured Obligations and
would be owed by the Borrower to the Secured Parties but for the fact that they
are unenforceable or not allowable due to the existence of a bankruptcy,
reorganization or similar proceeding involving any Credit Party.

                                       2
<PAGE>   221

              (b)    The Pledgor understands, agrees and confirms that the
Administrative Agent may enforce this Agreement against it without proceeding
against the Borrower or against any other credit or security for payment of the
Secured Obligations.

              3.     Pledge of Stock

              3.1.   Pledge. As collateral security for the prompt and complete
payment and performance when due of the Secured Obligations, the Pledgor hereby
pledges, hypothecates, assigns, transfers and sets over to the Administrative
Agent, grants to the Administrative Agent a security interest of first priority
in, and hereby delivers unto the Administrative Agent (in each case for the
benefit of the Secured Parties) the following (collectively, the "Pledged
Collateral"):

                     (i)   the Pledged Shares and any certificates or
              instruments representing the Pledged Shares, accompanied by duly
              executed stock powers in blank, and all cash, securities,
              dividends and other property at any time in the future and from
              time to time received, receivable or otherwise distributed, in
              respect of or in exchange for any or all of the Pledged Shares;

                     (ii)  all securities hereafter delivered to the
              Administrative Agent in substitution for or in addition to any of
              the foregoing, any certificates representing or evidencing such
              securities, and all cash, securities, dividends and other
              property, at any, time and from time to time received, receivable
              or otherwise distributed in respect of or in exchange for any or
              all of the foregoing;

                     (iii) all other claims of any kind or nature, and any
              instruments, certificates, chattel paper or other writings
              evidencing such claims, whether in contract or tort, and whether
              arising by operation of law, consensual agreement or otherwise, at
              any time acquired by the Pledgor in respect of any or all of the
              foregoing collateral against the Companies; and

                     (iv)  all proceeds of any of the foregoing including,
              without limitation (A) all rights of the Pledgor to receive monies
              due and to become due under or pursuant to the foregoing
              collateral; (B) all rights of the Pledgor to receive a return of
              any insurance premiums or Insurance Proceeds or other proceeds of
              any indemnity, warranty or guarantee with respect to the foregoing
              collateral, and (C) to the extent not included in the foregoing,
              all additions to and replacements of the foregoing collateral and
              all proceeds receivable or received when any and all of the
              foregoing collateral is sold, collected, exchanged or otherwise
              disposed whether voluntarily or involuntarily.

                                       3
<PAGE>   222

              3.2.   Uncertificated Stock. Notwithstanding anything to the
contrary contained in Section 3.1, if any Pledged Share (whether now owned or
hereafter acquired) is evidenced by an uncertificated security, the Pledgor
shall promptly notify the Administrative Agent thereof and shall promptly take
all actions required to perfect the security interest of the Administrative
Agent under applicable law (including, without limitation, under the Uniform
Commercial Code as adopted in any appropriate jurisdiction). The Pledgor further
agrees to take such actions as the Administrative Agent deems necessary or
desirable to effect the foregoing and to permit the Administrative Agent to
exercise any of its rights and remedies hereunder, and agrees to provide an
opinion of counsel reasonably satisfactory to the Administrative Agent with
respect to any such pledge of uncertificated Pledged Shares promptly upon
request of the Administrative Agent.

              4.     Appointment of Agents; Endorsements, etc. The
Administrative Agent shall have the right to appoint one or more agents for the
purpose of retaining physical possession of the Pledged Shares and other Pledged
Collateral, which may be held (in the discretion of the Administrative Agent) in
the name of the Pledgor, endorsed or assigned in blank or in favor of the
Administrative Agent or any nominee or nominees of the Administrative Agent or
an agent appointed by the Administrative Agent.

              5.     Representations, Warranties and Covenants. In order to

which it is a party, the Pledgor makes the following representations, warranties
and covenants, which representations, warranties and covenants shall survive the

consummation of the transactions contemplated hereby (i) are within its powers,
(ii) have been duly authorized by all necessary corporate action, (iii) do not
and will not contravene (A) its Governing Documents or (B) any material
Requirement of Law, any material Contractual Obligation or any material
Governmental Approval binding on or affecting it and (iv) do not and will not
conflict with or be inconsistent with or result in any breach of any of the
material terms, covenants, conditions or provisions of, or constitute a default
under, or result in the creation or imposition of (or the obligation to create
or impose) any Lien

                                       4
<PAGE>   223

terms of any material Contractual Obligation binding on or affecting it.

       (b)    Pledgor has duly executed and delivered this Agreement and this
Agreement constitutes the legal, valid and binding obligation of Pledgor,

insolvency, reorganization, moratorium or similar laws affecting creditors'
rights generally and (ii) general principles of equity.

              5.3.   Consents and Approvals. No consent of any other party

Pledgor) and no consent, authorization, approval or other action by, and no
notice to or filing with, any Governmental Authority is required either (i) for
the pledge by the Pledgor of the Pledged Collateral pursuant to this Agreement
or for the execution, delivery or performance by the Pledgor of this Agreement,
(ii) for the legality, validity, binding effect or enforceability hereof or
thereof or (iii) for the exercise by the Administrative Agent of the voting or
other rights provided for in this Agreement or the remedies in respect of the
Pledged Collateral pursuant to this Agreement (except as has been obtained or
made or as may be required in connection with disposition of any Pledged
Collateral by laws affecting the offering and sale of securities generally).

              5.4.   Litigation. There is no (i) injunction, writ, preliminary
restraining order or order of any nature issued by an arbitrator, court or other
Governmental Authority against Pledgor in connection with the transactions
provided for herein, or (b) action, suit, arbitration, litigation, investigation
or proceeding of or before any arbitrator or Governmental Authority pending
against Pledgor or, to Pledgor's knowledge, threatened against Pledgor which
would reasonably be expected to materially adversely affect the Pledged
Collateral or the right or ability of Pledgor to fulfill its obligations
hereunder.

              5.5.   No Defenses. The Pledgor's obligations under this Agreement
are not subject to any offsets or defenses against the Borrower, the

              5.6.   Compliance with Statutes, etc. The Pledgor is in compliance
in all material respects with all Requirements of Laws in respect of the conduct
of its business and the ownership of its property.

Investment Advisors Act of 1940, as amended or (ii) subject to regulation by the

<PAGE>   224

of a state public utility commission pursuant to Section 33(a)(2) of PUHCA is
required as a result of the investment of the Pledgor in the Companies.

              5.8.   Existence. The Pledgor shall preserve and maintain its
existence as a Person as specified in Section 5. 1.

              5.9.   Rights and Franchises. The Pledgor shall preserve and
maintain all of its rights, privileges and franchises necessary or desirable in
the normal conduct of its business, except where the failure to maintain any
such right, privilege or franchise could not reasonably be expected to have a
Material Adverse Effect.

              5.10.  Compliance with Requirements of Law. The Pledgor shall
comply in all material respects with the requirements of all material
Requirements of Law, except where the failure to comply could not reasonably be
expected to have a Material Adverse Effect or except when any such Requirements
of Law is being contested by the Pledgor in good faith and by appropriate
proceedings and pursuant to which contest Acceptable Reserves have been
established.

              5.11.  Share Transfer Restrictions. The Pledgor shall not sell,
assign, transfer or permit to be sold, assigned or transferred any of its
interests in the Companies, whether directly or indirectly, except pursuant to
the terms of this Agreement and the Credit Agreement. Except as set forth in
Section 7.09 of the Credit Agreement, nothing in this Agreement or the other
Financing Documents is intended to impose a restriction on the ability of the
holders of the Capital Stock of the Pledgor to sell, assign or transfer such
Capital Stock of the Pledgor.

              5.12.  Chief Executive Office. The chief executive office of the
Pledgor is located at the address set forth in Section 18 hereto. The Pledgor
shall not establish a new location for its chief executive office until (i) it
shall have given to the Administrative Agent not less than forty-five (45) days
prior written notice of its intention so to do, clearly describing such new
location and providing such other information in connection therewith as the
Administrative Agent may reasonably, request and (ii) with respect to such new
location, it shall have taken all action, reasonably satisfactory to the
Administrative Agent, to maintain the security interest of the Administrative
Agent in the Pledged Collateral intended to be granted hereby at all times fully
perfected, of first priority and in full force and effect.

              5.13.  Payment of Taxes. The Pledgor will, or will cause the
Companies to, timely pay and discharge or cause to be paid or discharged all
taxes, assessments and governmental charges or levies lawfully imposed upon it,
the Companies, any Borrower Entity or upon any of their respective income or
profits or upon any of the Portfolio Assets or the Collateral and all such
lawful claims or obligations that, if unpaid, would become a Lien upon the
Collateral (as defined in the Credit Agreement), whether real or personal, the
Pledged Collateral (as defined in this Agreement) or upon any part thereof;
provided, that the Pledgor shall have the right to contest in good faith the
validity or amount of any such tax, assessment, charge or levy by proper
proceedings, and may

                                       6
<PAGE>   225

permit the taxes, assessments, charges or levies so contested to remain unpaid
during the period of such contest if: (a) the Pledgor diligently prosecutes such
contest in good faith and by appropriate proceedings and has established
Acceptable Reserves; (b) during the period of such contest, the enforcement of
any contested item is effectively stayed; and (c) no Lien has been imposed on or
is about to be imposed on any of the Pledged Collateral.

              5.14.  Liquidity. Subject to the terms of this Section 5.14 below,
until the Secured Obligations have been indefeasibly paid in full and all
Commitments have been terminated, the Pledgor agrees to maintain an amount,
determined as of each April 15, June 30, September 30 and December 31 of each
year of the term hereof, of cash or cash equivalents not less than an amount
sufficient to pay all taxes, liens, assessments, liens, claims and obligations
required to be paid by the Pledgor pursuant to Section 5.13 above for the
twelve-month period immediately following the applicable date of determination
(the "Required Liquidity Level"). If, upon execution of this Agreement, the
Pledgor does not have cash or cash equivalents in an amount equal to the
Required Liquidity Level, then (a) it will retain, from the proceeds of any
issuance of debt or equity, an amount necessary to cause the Pledgor to meet the
estimated Required Liquidity Level as of the immediately following date of
determination; provided, that, Pledgor shall not be required to use proceeds of
an equity contribution made to it in respect of an identified investment to
satisfy the Required Liquidity Level, and (b) will retain, as cash or cash
equivalents any and all dividends or distributions received from the Companies
or any Borrower Entity until it has reached the Required Liquidity Level.
Amounts held by the Pledgor to meet the Required Liquidity Level (x) shall be
held free of any Liens or claims of any Person, (y) shall be held and reserved
by the Pledgor solely for the purpose of complying with its obligations under
Section 5.13 above in a segregated account, shall not be commingled with other
assets of the Pledgor or any other Person and shall not be held or used for the
satisfaction of other liabilities or obligations of the Pledgor or the
Companies, and (z) shall not be held out to any creditor of the Pledgor or the
Companies as being available for paying any liability or obligation of the
Pledgor or the Companies other than those contemplated by Section 5.13 above.
Notwithstanding the foregoing (i) in the event and for as long as indebtedness
of the Sponsor has an Investment Grade Rating, the Sponsor shall not be required
to comply with this Section 5.14, and (ii) in the event and for as long as the
Sponsor maintains a corporate revolving credit facility that can be used for
these purposes in an amount equal to at least four (4) times the Required
Liquidity Level, is not in default thereunder, and has availability thereunder
in an amount at least equal to twice the Required Liquidity Level, then the
Sponsor shall not be required to maintain cash or cash equivalents in a
segragated account as contemplated by this Section 5.14 and for so long as the
foregoing is true and correct, the Sponsor shall be deemed to have met the
estimated Required Liquidity Level without the requirement of any further
reserve or other act.

              5.15.  Pledged Shares.

              (a)    The Pledged Shares consist of the number and type of shares
of the Capital Stock of the Companies, as described in Exhibit A. All of the
Pledged Shares are certificated securities.

                                       7
<PAGE>   226

              (b)    The Pledged Shares are, and along with any securities
pledged in substitution therefor or in addition thereto will be, duly and
validly issued, fully paid and nonassessable and duly and validly pledged
hereunder in accordance with all applicable Requirements of Law, and the Pledgor
warrants, covenants and agrees to defend the Administrative Agent's right, title
and interest in and to the Pledged Shares and all other Pledged Collateral
against the claims and demands of all Persons whomsoever.

              (c)    The Pledgor is the record, legal and beneficial owner of,
and has good title to all of the Pledged Shares and all other Pledged
Collateral, free and clear of all Liens and other claims, security interests,
mortgages, pledges and other encumbrances of every nature whatsoever (other than
Permitted Liens) and it has the right to pledge the Pledged Shares and all other
Pledged Collateral as herein provided.

              (d)    The Pledged Shares constitute, and any securities pledged
in substitution therefor, or in addition thereto shall as of the date hereof
constitute, and shall, except as otherwise permitted hereby or by the Credit
Agreement, at all times constitute, one hundred percent (100%) of all the issued
and outstanding Capital Stock of the Companies. The Companies do not have
outstanding (i) any securities convertible into or exchangeable for their
Capital Stock or (ii) any rights to subscribe for or to purchase, or any options
for the purchase of, or any agreement, or any options for the purchase of, or
any agreement, arrangements or understandings providing for the issuance of its
Capital Stock.

              (e)    The Pledgor will not authorize the issuance by the
Companies of any additional stock of the Companies, (whether common or preferred
and whether of a class now or hereafter existing) unless concurrently with such
issuance all such stock is owned by Pledgor and made subject to the pledge of
shares hereunder. If the Pledgor shall acquire (by purchase, stock dividend or
otherwise) any additional shares in the Companies at any time or from time to
time after the date hereof, the Pledgor will forthwith pledge and deposit or
cause to be deposited such shares with the Administrative Agent and deliver or
cause to be delivered to the Administrative Agent certificates therefor,
accompanied by stock powers duly executed in blank by the Pledgor, and will
promptly thereafter deliver to the Administrative Agent a certificate executed
by any Responsible Officer of the Pledgor describing such shares and certifying
that the same have been duly pledged with the Administrative Agent hereunder.

              (f)    Each certificate evidencing the Pledged Shares is, and any
security pledged in substitution therefor or in addition thereto will be, issued
in the name of the Pledgor and each such certificate has been, or when issued
will then have been duly executed in blank or has, or when issued will then
have, attached thereto a stock power substantially in the form of Exhibit C duly
signed in blank by the appropriate officer of the Pledgor. Each such stock power
will give the Administrative Agent the rights and authority it purports to give.

              (g)    Upon receipt by the Administrative Agent of the stock
certificates representing the Pledged Shares, (which either have been duly
executed in blank or have

                                       8
<PAGE>   227

attached thereto stock powers substantially in the form of Exhibit C duly signed
in blank by the appropriate officer of the Pledgor), the security interest
described in this Agreement will represent a valid and perfected first priority
lien on, and security interest in, the Pledged Collateral, in favor of the
Administrative Agent for the benefit of the Secured Parties.

              (h)    The Pledgor has not executed, or authorized and there does
not currently exist, any effective financing statement or other instrument
similar in effect that is on file in any recording office covering all or any
part of the Pledgor's interest in the Pledged Collateral, except such as may
have been filed pursuant to this Agreement or the other Financing Documents,
and, so long as any of the Secured Obligations remain unpaid or any Commitments
remain outstanding, the Pledgor will not execute or authorize to be filed in any
public office any financing statement (or similar statement or instrument of
registration under the law of any jurisdiction) or statements relating to the
Pledged Collateral, except financing statements filed or to be filed in respect
of and covering the security interests granted hereby by the Pledgor. Upon the
completion of all filings and recordings described in Exhibit B, no filings or
recordings (including, without limitation, under the Uniform Commercial Code as
adopted in the State of New York) will be necessary to be made in order to
perfect, protect and preserve the lien on and security interest in the Pledged
Collateral created by this Agreement.

              (i)    The Pledgor will not hereafter create or permit to exist
any Lien, security interest or other charge, encumbrance or other security
arrangement upon or with respect to, any of the Pledged Collateral (other than
Liens created under this Agreement or Permitted Liens), until the Secured
Obligations are indefeasibly paid or otherwise discharged in full.

              (j)    None of the Pledged Shares constitutes margin stock, as
defined in Regulation U of the Board of Governors of the Federal Reserve System.

              6.     Voting, and Corporate Rights. Unless and until an Event of
Default shall have occurred and be continuing and the Pledgor shall have been
notified by the Administrative Agent of the Secured Parties' written election to
exercise remedies hereunder, the Pledgor shall be entitled to exercise any
voting and corporate rights with respect to the Pledged Shares or any securities
pledged in substitution therefor or in addition thereto for any purpose, and in
any manner, not inconsistent with the terms hereof; provided, that, no vote
shall be cast or any consent, waiver or ratification given or any action taken
which would violate or be inconsistent with any of the terms of this Agreement,
the Credit Agreement or any other Financing Document, and provided, further,
that, the Pledgor shall not exercise or refrain from exercising any such voting
and other rights if it could reasonably be anticipated that such action would
have an adverse effect on the creation, attachment, perfection or priority of
the security interests herein granted in the Pledged Collateral to the
Administrative Agent (or any part thereof). Upon the Pledgor's receipt of a
notice in accordance with the first sentence of this Section 6, and during the
continuance of an Event of Default, all such rights of the Pledgor to vote

                                       9
<PAGE>   228

and to give consents, waivers and ratifications shall be exercisable solely by
the Administrative Agent in accordance with Section 8.

              7.     Dividends and Other Distributions. Unless and until an
Event of Default shall have occurred and be continuing, all cash dividends
payable in respect of the Pledged Shares that represent Permitted Distributions
under the terms of the Credit Agreement shall be paid to the Pledgor and shall
not be part of the Pledged Collateral; provided, that, any dividends or
distributions payable in respect of the Pledged Shares made in contravention of
the Credit Agreement or which represent in whole or in part an extraordinary,
liquidating or other distribution in return of capital shall be paid to the
Administrative Agent and retained by it as part of the Pledged Collateral. The
Administrative Agent shall also be entitled at all times to receive directly,
and to retain as part of the Pledged Collateral:

              (a)    all other or additional stock or securities or property
(other than cash) paid or distributed by way of dividend in respect of the
Pledged Shares;

              (b)    all other or additional stock or other securities or
property (including cash) paid or distributed in respect of the Pledged Shares
by way of stock-split, spin-off, split-up, reclassification, combination of
shares or similar rearrangement; and

              (c)    all other or additional stock or other securities or
property, which may be paid in respect of the Pledged Collateral by reason of
any consolidation, merger, exchange of stock, conveyance of assets, liquidation
or similar corporate reorganization.

              8.     Remedies Upon Default. If an Event of Default shall have
occurred and be continuing, the Administrative Agent, acting pursuant to and in
accordance with the terms and conditions of the Credit Agreement and the
direction of the Required Lenders thereunder, shall be entitled to exercise all
the rights, powers and remedies vested in it (whether vested in it by this
Agreement, the Credit Agreement or any other Financing Document or by law) for
the protection and enforcement of its rights in respect of the Pledged
Collateral and, without limitation of the foregoing, may cause all or any of the
Pledged Shares or other Pledged Collateral to be transferred into its name or
that of a nominee or nominees, and the Pledgor shall, upon the request of the
Administrative Agent, execute such additional instruments and documents as are
necessary to effect such transfer.

              (a)    In addition, if an Event of Default shall have occurred and
be continuing, the Administrative Agent, acting pursuant to and in accordance
with the terms and conditions of the Credit Agreement and the direction of the
Required Lenders thereunder, without being required to give any notice to the
Pledgor or the Companies (except in respect of actions taken pursuant to Section
8(a)(i) or Section 8(a)(ii)), shall be entitled to exercise the following
rights, which, the Pledgor agrees, are commercially reasonable:

                                       10
<PAGE>   229

              (i)    to exercise any and all voting rights with respect to the
       Pledged Shares and other Pledged Collateral, including the appointment
       and removal of any proxy or proxies or substitute or substitutes;

              (ii)   to receive and retain, as collateral security for the
       Secured Obligations, any and all dividends at any time and from time to
       time declared or paid upon any of the Pledged Shares and other Pledged
       Collateral otherwise payable to the Pledgor;

              (iii)  to accept rights issues;

              (iv)   to prove in any liquidation or scheme of arrangement or any
       other composition or arrangement with or for creditors whether secured or
       unsecured and whether formed pursuant to the order of any court or
       otherwise, and to give any consent on behalf of the Pledgor in relation
       thereto;

              (v)    to attend meetings of creditors and vote;

              (vi)   to compromise claims in relation to or arising out of the
       Pledged Shares;

              (vii)  to give sufficient receipts and discharges for all monies
       to which the Pledgor is or may become entitled in respect of the Pledged
       Shares or any part thereof or which shall come into the hands of the
       Administrative Agent, which receipts and discharges shall, to the maximum
       extent permitted by Requirements of Law, exonerate the Administrative
       Agent from all liability to see to the application thereof or from being
       answerable for the loss or misapplication thereof;

              (viii) to execute any documents which it may consider expedient,
       in good faith, in relation to the foregoing as it shall in its absolute
       discretion determine (but without any obligation to consult with the
       Pledgor) in relation to any exercise of any such right, power or
       privilege; and

              (ix)   to institute, prosecute and defend any proceedings in any
       court or tribunal in respect of any act or transaction referred to in
       this Section 8(a).

              (b)    (i) Without obligation to resort to other security or
marshal assets for disposition in any particular order or priority whatsoever,
the Administrative Agent shall have the right at any time and from time to time
upon the occurrence and during the continuance of an Event of Default to sell,
resell, assign and deliver, all or any of the Pledged Shares or other Pledged
Collateral, in one or more parcels at the same or different times, and all
rights, titles and interests, claims and demands therein and right of redemption
thereof, on any securities exchange on which the Pledged Shares, any security
pledged in substitution therefor or in addition thereto or any of them may then
be listed, or at public or private sale, for cash, upon credit or for future
delivery, and at such price

                                       11
<PAGE>   230

or prices, on such terms as the Secured Parties (acting pursuant to the Credit
Agreement) may determine and in compliance with such conditions as the Secured
Parties (acting pursuant to the Credit Agreement) may in their absolute
discretion deem advisable, provided such sale is conducted in a commercially
reasonable manner in accordance with applicable law. The Pledgor hereby agrees
that upon such sale, any and all equity or right of redemption, stay or approval
of the Pledgor shall be automatically waived and released without any further
action on the part of the Pledgor, all without either demand, advertisement or
notice (except as required by Requirements of Law), all of which (to the extent
permitted by Requirements of Law) are hereby expressly waived by the Pledgor.

              (ii)   In the event of any such sale, the Administrative Agent
shall, at least ten (10) Business Days before the sale, give the Pledgor notice
of its intention to sell except that, if any Secured Party shall determine, in
its sole discretion, that any of the Pledged Shares or other Pledged Collateral
threatens to decline quickly in value or to become worthless, any such sale may
be made upon three days' notice to the Pledgor.

              (iii)  The Administrative Agent agrees that upon the indefeasible
payment and performance in full of the Secured Obligations and the termination
of all Commitments, prior to any such sale, such sale shall be cancelled.

              (iv)   Upon each such sale, the Administrative Agent or any other
Secured Party may purchase all or any of the Pledged Shares or other Pledged
Collateral being sold, free from any equity or right of redemption, which upon
each such sale shall, to the extent permitted by Requirements of Law, be waived
and released.

              (v)    The proceeds of each such sale shall be applied by the
Administrative Agent as provided in Section 11.

              (vi)   For the purposes of this Section 8(b), an agreement to sell
any or all of the Pledged Shares or other Pledged Collateral entered into
following any Event of Default shall, to the extent permitted by Requirements of
Law, be treated as a sale thereof, and the Administrative Agent shall be free to
carry out such sale pursuant to such agreement and the Pledgor shall not be
entitled to the return of any of the Pledged Shares or other Pledged Collateral
subject thereto notwithstanding the fact that, after the Administrative Agent
shall have entered into any such agreement, the Secured Obligations shall have
been paid in full.

              (vii)  The Administrative Agent shall not be obligated to make any
sale of the Pledged Collateral if it shall determine not to do so, regardless of
the fact that notice of sale of the Pledged Collateral may have been given.

              (viii) The Administrative Agent, may without notice, adjourn any
public or private sale or cause the same to be adjourned from time to time by
announcement at the time and place fixed for sale, and such sale may, without
further notice, be made at the time and place to which the same was so
adjourned.

                                       12
<PAGE>   231

              (ix)   In case sale of all or any part of the Pledged Collateral
is made on credit or for future delivery, the Pledged Collateral so sold may be
retained until the sale price is paid by the purchaser or purchasers thereof,
but the Administrative Agent shall not incur any liability in case any such
purchaser or purchasers shall fail to take up and pay for the Pledged Collateral
so sold and, in case of any such failure, such Pledged Collateral may be sold
again upon like notice.

              (x)    Neither the Administrative Agent nor any other Secured
Party shall be liable for failure to collect or realize upon any or all of the
Pledged Collateral or for any delay in so doing nor shall any of them be under
any obligation to take any action whatsoever with regard thereto.

              (xi)   As an alternative to exercising the power of sale herein
conferred upon it, the Administrative Agent may proceed by a suit or suits at
law or in equity to foreclose this Agreement and to sell the Pledged Collateral,
or any portion thereof, pursuant to a judgment or decree of a court or courts of
competent jurisdiction.

              (c)    The Administrative Agent shall have the right, for and in
the name, place and stead of the Pledgor, to execute endorsements, assignments
or other instruments of conveyance or transfer with respect to all or any of the
Pledged Shares and other Pledged Collateral in connection with any sale thereof
in accordance with Section 8(a) or (b).

              9.     Remedies Cumulative: Indemnification of the Administrative
Agent and the Other Secured Parties. (a) No failure or delay on the part of the
Administrative Agent or any Secured Party in exercising any right, power or
privilege hereunder or under any other Financing Document and no course of
dealing between Pledgor and the Administrative Agent or any Secured Party shall
operate as a waiver thereof; nor shall any single or partial exercise of any
right, power or privilege hereunder or under any other Financing Document
preclude any other or further exercise thereof or the exercise of any other
right, power or privilege hereunder or thereunder. The rights, powers and
remedies herein or in any other Financing Document expressly provided are
cumulative and not exclusive of any rights, powers or remedies which the
Administrative Agent or any Secured Party would otherwise have. No notice to or
demand on Pledgor in any case shall entitle Pledgor to any other or further
notice or demand in similar or other circumstances or constitute a waiver of the
rights of the Administrative Agent or any Secured Party to any other or further
action in any circumstances without notice or demand.

              (b)    The Pledgor hereby agrees to indemnify and hold harmless
the Administrative Agent and each other Secured Party from and against any loss,
liability or expense (including reasonable fees and disbursements of counsel for
the Administrative Agent and each other Secured Party) which may be incurred by
the Administrative Agent or any other Secured Party (except as a result of the
gross negligence or willful misconduct of any Secured Party) as a result of or
in connection with:

                                       13
<PAGE>   232

              (i)    any failure of the Pledgor to fulfill its obligations under
       this Agreement, upon demand by the Administrative Agent, including,
       without limitation, costs and expenses of enforcement of any obligation
       of the Pledgor to make any such payment hereunder and any other
       obligation, covenant or agreement of the Pledgor hereunder,

              (ii)   the enforcement, discharge, improvement and protection of
       the interest of the Administrative Agent hereby created;

              (iii)  the exercise or attempted exercise of any right, authority,
       power or remedy conferred on the Administrative Agent under or by virtue
       of this Agreement or by statute, and

              (iv)   the assisting or defending of any right, title or interest
       of the Pledgor or the Administrative Agent or any other Secured Party in
       connection with the Pledged Shares.

              10.    Obligations Absolute. (a) The obligations of the Pledgor
hereunder shall not be altered or affected by the validity, regularity or
enforceability of any provision of the Credit Agreement or any other Transaction
Document, any compromise, alteration, amendment, modification, extension,
renewal, release or other chance of, or any waiver, consent or other action in
respect of, any of the terms, covenants or conditions of any of such agreements,
the recovery of any judgment against any Person or any action to enforce the
same, any failure or delay in the enforcement of the obligations of the Borrower
under any of the Financing Documents or any other circumstances. The Pledgor
hereby expressly and irrevocably, waives all defenses, setoffs, counterclaims,
recoupments, terminations or impairments whether arising hereunder or otherwise.
The Pledgor hereby covenants that this Agreement shall not be discharged except
by payment and performance in full of the Secured Obligations.

              (b)    Without limiting the generality of the foregoing, the
obligations of the Pledgor hereunder and the rights of the Administrative Agent
to enforce the same by proceedings whether by action at law, suit in equity or
otherwise, shall not be in any way affected by (x) any insolvency, bankruptcy,
liquidation, reorganization, readjustment, composition, dissolution, winding up
or other proceeding, involving or affecting the Borrower, the Companies, the
Pledgor or any other Person or (y) any change in the ownership of the Borrower,
the Companies, the Pledgor or any other Person. To the fullest extent permitted
by law, the Pledgor releases and waives any legal or equitable defenses to the
enforceability of its obligations hereunder, and the Pledgor agrees that its
obligations shall be absolute and unconditional and shall not be affected or
discharged by any circumstance, act or event except the indefeasible payment in
full of the Secured Obligations and termination of all Commitments, including,
without limitation, the following:

              (i)    the exchange, sale or release of any security for the
       Secured Obligations;

                                       14
<PAGE>   233

              (ii)   the failure to enforce any guaranty or security given or
       promised by any other Person or the waiver, compromise or release of such
       other guaranty or security;

              (iii)  the extension of time for the performance of any
       obligations in respect of the Secured Obligations or the Pledgor's
       obligations hereunder; or

              (iv)   the failure to give notice to the Pledgor of any nonpayment
       or other breach in respect of the Secured Obligations.

              (c)    The Pledgor hereby expressly and irrevocably waives notice
of acceptance of this Agreement, notice of any liability to which it may apply,
presentment, demand, protest, notice of dishonor, non-payment, or
nonperformance, any proceeding to enforce any provision of any Transaction
Document and any right to require a proceeding prior to payment hereunder
against the Borrower or any other Person.

              11.    Application of Proceeds. Notwithstanding any other
provision of this Agreement, all moneys collected by the Administrative Agent
upon any sale or other disposition of the Pledged Collateral, together with all
other moneys received by the Administrative Agent hereunder, shall be applied in
accordance with the Deposit Account Agreement.

              12.    Purchasers of Pledged Collateral. Upon any sale of the
Pledged Collateral by the Administrative Agent hereunder (whether by virtue of
the power of sale herein, granted, pursuant to judicial process or otherwise),
the receipt of the Administrative Agent or the officer making the sale shall be
a sufficient discharge to the purchaser or purchasers of the Pledged Collateral
so sold, and such purchaser or purchasers shall not be obligated to see to the
application of any part of the purchase money paid over to the Administrative
Agent or such officer or be answerable in any way for the misapplication or
nonapplication thereof.

              13.    Continuing Obligation. This Agreement is a continuing
obligation of the Pledgor and shall (a) be binding upon the Pledgor, and upon
the successor and assigns of the Pledgor, (b) inure to the benefit of and be
enforceable by the Administrative Agent and the other Secured Parties and their
respective successors and assigns and (c) remain in full force and effect until
no Lender shall have any Commitment outstanding and until the Notes, together
with interest, and all other Secured Obligations are indefeasibly paid in full.

              14.    Administrative Agent. Bank of America, N.A. (or any
successor) has been appointed by the Secured Parties to act as the
Administrative Agent hereunder. The Administrative Agent is hereby appointed,
which appointment is irrevocable and coupled with an interest, the
attorney-in-fact of the Pledgor for the purpose of carrying out the provisions
hereof and taking any action and executing any instruments which the
Administrative Agent may deem necessary or advisable to accomplish the purposes

                                       15
<PAGE>   234

hereof and to do all acts and things which under any of the covenants and
agreements herein contained or implied ought to be done by the Pledgor or which
the Administrative Agent is hereby or by virtue hereof or by statute authorized
or empowered to do.

              15.    Waiver of Subrogation. Without limiting the generality of
the foregoing, while this Agreement is in effect, the Pledgor hereby irrevocably
waives (a) any rights which it may acquire by way of subrogation under this
Agreement, whether such subrogation rights arise by any payment made hereunder
or any set-off or application of funds of the Pledgor by the Administrative
Agent or otherwise, and (b) any right of reimbursement or contribution against
any Borrower Entity or the Companies or any other security or guarantee or right
of offset held by the Administrative Agent therefor. If, notwithstanding the
preceding sentence, any amount shall be paid to the Pledgor on account of any
subrogation rights in connection with this Agreement at any time when all of the
Secured Obligations shall not have been paid in full, such amount shall be held
by the Pledgor in trust for the Administrative Agent for the benefit of the
Secured Parties, segregated from other funds of the Pledgor, and shall,
forthwith upon receipt by the Pledgor, be turned over to the Administrative
Agent in the exact form received by the Pledgor (duly endorsed by, the Pledgor
to the Administrative Agent, if required), to be applied as provided in Section
11.

              16.    Successors and Assigns. This Agreement shall be binding
upon and inure to the benefit of and be enforceable by the respective successors
and assigns of the parties hereto and shall inure to the benefit of the Secured
Parties and their respective successors and assigns; provided, that, the Pledgor
may not assign or transfer any of its rights or obligations hereunder without
the prior written consent of each of the Lenders. The Administrative Agent may
transfer, assign or grant its rights hereunder in connection with an assignment
or transfer of all or any part of its interest in and rights under the Credit
Agreement.

              17.    Severability. If any term or provision hereof or the
application thereof to any circumstance shall, in any jurisdiction and to any
extent, be invalid or unenforceable, such term or provision shall be ineffective
as to such jurisdiction to the extent of such invalidity or unenforceability
without invalidating or rendering unenforceable the remaining terms and
provisions hereof or the application of such term or provision to circumstances
other than those as to which it is held invalid or unenforceable. To the extent
permitted by applicable law, the parties hereto hereby waive any provision of
law which renders any term or provision invalid or unenforceable in any respect.

              18.    Notices. All notices, requests and other communications to
the Pledgor or the Administrative Agent shall be in writing (including telecopy
or similar teletransmission or writing) and shall be given to such party at its

              23.    Execution of Counterparts. This Agreement may be executed
in any number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed shall be deemed to be an original
and all of which taken together shall constitute one and the same instrument.

              24.    Amendment; Waiver. No amendment or waiver of any provision
of this Agreement shall be effective unless the same shall be undertaken and
accomplished in accordance with the requirements of Section 9.02 of the Credit
Agreement. No delay on the part of any Secured Party in the exercise of any
right, power or remedy shall operate as a waiver thereof, nor shall any single
or partial waiver by such Secured Party of any right, power or remedy preclude
any further exercise thereof, or the exercise of any other right, power or
remedy.

              25.    Further Assurances. The Pledgor hereby agrees, at its own
expense, to execute and deliver, from time to time, any and all further or other
instruments and to perform such acts, as the Administrative Agent or any other
Secured Party may reasonably request to effect the purposes of this Agreement
and to secure to the Administrative Agent and the other Secured Parties the
benefits of all rights, powers and remedies conferred upon the Administrative
Agent by the terms of this Agreement. In the event that at any time hereafter,
due to any change in circumstances, including without limitation, any change in
an applicable law, or any decision hereafter made by a court construing any
applicable law, it is, in the opinion of counsel for any Secured Party,
necessary or desirable to file or record this Agreement or any Uniform
Commercial Code financing, statement or other instrument or document respecting
this Agreement or the pledge made hereunder, the Pledgor agrees to pay all fees,
costs and expenses of such recording, or filing and to execute and deliver any
instruments that may be necessary or appropriate to make such filing or
recording effective.

              26.    Applicability of the Credit Agreement. Notwithstanding any
other provision of this Agreement, in connection with its obligations hereunder
the Administrative Agent has all of the rights, powers, privileges,
exculpations, protections, and indemnities as are provided for or referred to in
the Credit Agreement.

              27.    Limitation on Recourse. The obligations of the Pledgor
hereunder are obligations solely of the Pledgor and shall not constitute a debt
or obligation of any direct or indirect partner or shareholder of the Pledgor or
any of their respective directors, officers, agents or employees (each such
Person, a "Non-Recourse Party"). No Non-Recourse Party shall be liable for any
amount payable by the Pledgor under this Agreement and the Secured Parties shall
not seek a money judgment or deficiency or personal judgment against any
Non-Recourse Party for payment of the indebtedness payable by the Pledgor
evidenced by this Agreement. No property or assets of any Non-Recourse Party,
other than as contemplated in the Financing Documents, shall be sold, levied
upon or otherwise used to satisfy any judgment rendered in connection with any
action brought against the Pledgor with respect to this Agreement or the other
Financing Documents. The foregoing acknowledgements, agreements and waivers
shall be enforceable by any Non-Recourse Party. Notwithstanding the foregoing,
nothing in this

                                       19
<PAGE>   238

Section shall limit or affect or be construed to limit or affect the obligations
and liabilities of any Credit Party or any other Non-Recourse Party (a) in
accordance with the terms of any Transaction Document or Financing Document
creating such liabilities and obligations to which such Credit Party or
Non-Recourse Party is a party, (b) arising from liability pursuant to applicable
Requirements of Law for such Credit Party's or such Non-Recourse Party's
fraudulent actions, knowing misrepresentations or willful misconduct or (c) with
respect to amounts distributed to it in violation of Section 6.10 of the Credit
Agreement.

                      PARTNERSHIP INTEREST PLEDGE AGREEMENT

       PARTNERSHIP INTEREST PLEDGE AGREEMENT, dated as of July 28, 1999 (this
"Agreement"), made by ORION POWER NEW YORK GP, INC., a Delaware corporation
("Pledgor"), as the obligor hereunder, to BANK OF AMERICA, N.A., as
administrative agent (the "Administrative Agent") for the Secured Parties (as
defined in the Credit Agreement referred to below).

                              W I T N E S S E T H:

       WHEREAS, Pledgor is the sole general partner of (a) Orion Power New York,
L.P., a Delaware limited partnership (the "Borrower") and (b) each of (i)
Astoria Generating Company, L.P., a Delaware limited partnership, (ii) Carr
Street Generating Station, L.P., a Delaware limited partnership, and (iii) Erie
Boulevard Hydropower, L.P., a Delaware limited partnership, (each, an "Operating
Company" and together with the Borrower, the "Borrower Entities")

       WHEREAS, the Borrower has entered into a Credit Agreement, dated as of
July 28, 1999 (as the same may be amended, supplemented or otherwise modified
from time to time, the "Credit Agreement"), with the Administrative Agent, Banc
of America Securities LLC and Paribas, as lead arrangers (the "Lead Arrangers"),
Bank of America, N.A., as Issuing Bank and the Lenders named on the signature
pages thereto and from time to time parties thereto (the "Lenders") (all
capitalized terms used herein and not otherwise defined herein shall have the
meanings attributed to them in the Credit Agreement), pursuant to which the
Lenders have agreed, inter alia, to make available credit facilities to the
Borrower to finance a portion of the purchase price of the Portfolio Assets and
to provide working capital availability to the Borrower;

       WHEREAS, the Credit Agreement contemplates the execution, delivery and
the implementation of this Agreement;

       WHEREAS, it is a condition precedent to the obligations of the Lenders
under the Credit Agreement that this Agreement shall have been entered into by
the parties hereto and shall have become unconditionally and fully effective in
accordance with the terms hereof; and

       WHEREAS, the Borrower, the Administrative Agent and the Lenders have
entered into a Deposit Account Agreement, dated as of July 28, 1999 (as the same
may be amended, supplemented or otherwise modified from time to time, the
"Deposit Account Agreement"), providing for, among other things, the
establishment of the Accounts and the application of the proceeds of the
Collateral;

         NOW, THEREFORE, in consideration of the foregoing and in order to
induce the Lenders to enter into the Credit Agreement, to make available to the
Borrower such credit facilities and for other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, Pledgor hereby
agrees as follows:

                                       1
<PAGE>   248

       SECTION 1. Pledge; Assignment; Grant of Security Interest. Pledgor hereby
pledges, hypothecates and assigns to the Administrative Agent, and hereby grants
to the Administrative Agent for the benefit of the Secured Parties, a pledge and
assignment of, and a security interest in, all of its right, title and interest
in and to the following (the "Collateral"):

       (a)    All general and limited partnership interests now owned or
hereafter acquired by Pledgor in and to each Borrower Entity (collectively, the
"Partnership Interests") and the partnership agreement relating to each Borrower
Entity (collectively, the "Partnership Agreements") and all rights related
thereto, including, without limitation, (i) all rights of Pledgor as a general
or limited partner, as the case may be, and all rights to receive distributions,
cash, instruments and other property from time to time receivable or otherwise
distributable in respect of any Partnership Interest or pursuant to any
Partnership Agreement, (ii) all rights of Pledgor to receive proceeds of any
insurance, indemnity, warranty or guaranty with respect to any Partnership
Interest or any Partnership Agreement, (iii) all claims of Pledgor for damages
arising out of or for breach of or default under any Partnership Agreement, (iv)
the right of Pledgor to terminate any Partnership Agreement, to perform and
exercise consensual or voting rights thereunder and to compel performance and
otherwise exercise all remedies thereunder, (v) all rights of Pledgor as a
general or limited partner of any of the Borrower Entities, to any property and
assets of the Borrower Entities (whether real property, inventory, equipment,
contract rights, accounts, receivables, general intangibles, securities,
instruments, chattel paper, documents, chooses in action or otherwise), and (vi)
all certificates or instruments evidencing an ownership or partnership interest
in the Borrower Entities or their assets; and

       (b)    to the extent not included in the foregoing, all proceeds of any
and all of the foregoing (including, without limitation, proceeds that
constitute property of the types described above).

       SECTION 2. Security for Secured Obligations. This Agreement secures the
prompt and complete payment and performance of (a) all Obligations of the
Borrower now or hereafter existing under the Financing Documents, (b) all
obligations of each Operating Company under the Subsidiary Guarantees and (c)
the due performance and compliance of all other obligations of any Borrower
Entity under any of the Financing Documents (collectively, the "Secured
Obligations"). Without limiting the generality of the foregoing, this Agreement
secures the payment of all amounts which constitute part of the Secured
Obligations and would be owed by the Borrower to the Secured Parties but for the
fact that they are unenforceable or not allowable due to the existence of a
bankruptcy, reorganization or similar proceeding involving any Credit Party.

       SECTION 3. Pledgor Remains Liable. Anything herein to the contrary
notwithstanding, (a) Pledgor shall remain liable under each Partnership
Agreement and the other contracts and agreements included in the Collateral to
the extent set forth therein to perform all of its duties and obligations
thereunder to the same extent as if this Agreement had not been executed, (b)
the exercise by any Secured Party of any of the rights hereunder shall not
release Pledgor from any of its duties or obligations under the contracts and
agreements included in the Collateral and (c) neither the Administrative Agent
nor any Secured Party shall have any obligation or liability under the contracts
and agreements included in the Collateral or otherwise by reason of this

                                       2
<PAGE>   249
Agreement, nor shall the Administrative Agent or any Secured Party be obligated
to perform any of the obligations or duties of Pledgor thereunder or to take any
action to collect or enforce any claim assigned hereunder.

       SECTION 4. Delivery of Collateral. All certificates or instruments
representing or evidencing the Collateral at any time shall be delivered to and
held by or on behalf of the Administrative Agent pursuant hereto and shall be in
suitable form for transfer by delivery, or shall be accompanied by duly executed
instruments of transfer or assignment in blank, all in form and substance
satisfactory to the Administrative Agent. The Administrative Agent shall have
the right, upon the occurrence and continuance of an Event of Default, in its
discretion and without notice to Pledgor, to transfer to or to register in the
name of the Administrative Agent or any of its nominees any or all of the
Collateral, subject only to compliance with Requirements of Law, the terms and
conditions of the Credit Agreement and the revocable rights specified in Section
9(a). In addition, the Administrative Agent shall have the right at any time to
exchange certificates or instruments representing or evidencing Collateral for
certificates or instruments of smaller or larger denominations.

       SECTION 5. No Subrogation. Pledgor shall not exercise any rights which
it may acquire by way of subrogation under this Agreement, by any payments made
hereunder or otherwise, until all Secured Obligations shall have been
indefeasibly paid in full and all Commitments have been terminated. If any
amount shall be paid to Pledgor on account of such subrogation rights at any
time when all Secured Obligations shall not have been indefeasibly paid in full
(whether pursuant to a claim in any bankruptcy or similar proceeding or
otherwise) or when any Commitment shall remain outstanding, such amount shall
be held in trust for the benefit of the Administrative Agent and the Secured
Parties and shall forthwith be paid to the Administrative Agent to be credited
and applied to the Secured Obligations, whether matured or unmatured, in
accordance with Section 17.

       SECTION 6. Reinstatement. This Agreement shall continue to be
effective, or be reinstated, as the case may be, if at any time payment, or any
part thereof, of any of the Secured Obligations is rescinded or must otherwise
be restored or returned by any Secured Party upon the insolvency, bankruptcy,
dissolution, liquidation or reorganization of Pledgor, or upon or as a result
of the appointment of a receiver, intervenor or conservator of, or trustee or
similar officer for, Pledgor or any substantial part of its property, or
otherwise, all as though such payments had not been made.

       SECTION 7. Representations and Warranties.  Pledgor represents and
warrants as follows:

       (a)    Pledgor (i) is duly formed, validly existing and in good standing
under the laws of the State of Delaware, (ii) has all requisite power and

engaged, (iii) has duly qualified and is authorized to do business and is in
good standing in every jurisdiction where the character of its properties or the
nature of its activities makes such qualification necessary and (iv) is in full
compliance with its Governing Documents, all material Contractual Obligations,
all applicable material Requirements of Law and all

                                       3

material Governmental Approvals. As of the date hereof, (x) Pledgor is the sole
General Partner of the Borrower; (y) the Operating Companies are the only
Subsidiaries of the Borrower; and (z) Pledgor is the sole General Partner of
each Operating Company.

       (b)    The execution, delivery and performance by Pledgor of this
Agreement and the consummation of the transactions contemplated hereby (i) are
within its powers, (ii) have been duly authorized by all necessary corporate
action, (iii) do not and will not contravene (A) its Governing Documents or (B)
any material Requirement of Law, any material Contractual Obligation or any
material Governmental Approval binding on or affecting it and (iv) does not and
will not conflict with or be inconsistent with or result in any breach of any of
the material terms, covenants, conditions or provisions of, or constitute a
default under, or result in the creation or imposition of (or the obligation to
create or impose) any Lien (except Permitted Liens) upon any of its properties
or assets pursuant to, the terms of any material Contractual Obligation binding
on or affecting it.

       (c)    Pledgor has duly executed and delivered this Agreement and this
Agreement constitutes the legal, valid and binding obligation of Pledgor,
enforceable against Pledgor in accordance with its terms, except as enforcement
thereof may be subject to (i) the effect of any applicable bankruptcy,
insolvency, reorganization, moratorium or similar laws affecting creditors'
rights generally and (ii) general principles of equity.

       (d)    No Governmental Approval or approval of any other Person (except
such as have been duly obtained, made or given, and are in full force and
effect) is required to authorize, or is required in connection with (i) the
execution, delivery or performance of this Agreement by Pledgor or the
consummation of any of the transactions contemplated hereby, (ii) the legality,
validity, binding effect or enforceability of this Agreement or the perfection
and maintenance of the security interest created hereby (including the first
priority nature of such security interest) or (iii) for the exercise by the
Administrative Agent of the voting or other rights provided for in this
Agreement or the remedies in respect of the Collateral pursuant to this
Agreement. All applicable waiting periods relating to any such Governmental
Approval or other approval which are required and have been obtained have
expired without any adverse action taken with respect thereto.

       (e)    Each Partnership Agreement, true and complete copies of which have
been furnished to the Administrative Agent, has been duly authorized, executed
and delivered by Pledgor and is in full force and effect and is binding upon and
enforceable against Pledgor in accordance with its terms. There exists no
default under any Partnership Agreement.

       (f)    This Agreement creates a valid security interest in the Collateral
purported to be pledged and assigned by Pledgor hereunder securing the payment
of the Secured Obligations.

       (g)    Upon the filing of the financing statements (the "Financing
Statements") referenced in Schedule I hereof under the Uniform Commercial Code
as in effect in the State of Delaware (the "Delaware UCC"), the security
interest is created hereby shall be perfected under the Delaware UCC, to the
extent that the Collateral constitutes "general intangibles" (as defined in the
Delaware UCC) and no further filings or other actions are necessary to perfect
such

                                       4
<PAGE>   251

security interest. Upon filing of such Financing Statements pursuant to the
Delaware UCC, such security interests, as so perfected, are first priority
security interests.

       (h)    When any certificates or instruments evidencing the Collateral
shall be delivered hereunder, and for so long as such certificates or
instruments shall remain in the possession of the Administrative Agent in the
State of New York or the State of North Carolina, the security interest in such
Collateral created hereby shall be perfected under the Uniform Commercial Code
as in effect in the State of New York (the "NY UCC") or the State of North
Carolina, as applicable, and such security interest, as so perfected, will be a
first priority security interest.

       (i)    The security interest created by this Agreement in the Collateral
described in clause (a) of Section 1 hereof has been registered in the name of
the Administrative Agent in the register maintained for such purpose at the
chief executive office and principal place of business of the Borrower and each
Operating Company, as applicable, and, to the extent that such Collateral
constitutes "uncertificated securities" (as defined in the Delaware UCC), such
security interest is perfected under the Delaware UCC and, as so perfected, is a
first priority security interest.

       (j)    The chief place of business and chief executive office of Pledgor
and the office where Pledgor keeps its records concerning the Collateral is set
forth under its name on the signature page hereof.

       (k)    Pledgor is the legal and beneficial owner of the Collateral
purported to be pledged and assigned by it hereunder, free and clear of any
Lien, other than Permitted Liens. No effective financing statement or other
instrument similar in effect covering all or any part of such Collateral has
been executed or authorized by Pledgor or, is on file in any recording office,
except such as may have been filed in favor of the Administrative Agent relating
to this Agreement. Pledgor has no trade name.

       (l)    There are no conditions precedent to the effectiveness of this
Agreement that have not been satisfied or waived.

       (m)    No part of the Collateral is subject to the terms of any agreement
restricting the sale or transfer of such Collateral, except for the Partnership
Agreements and the Financing Documents.

       (n)    There is no (i) injunction, writ, preliminary restraining order or
order of any nature issued by an arbitrator, court or other Governmental
Authority against Pledgor in connection with the transactions provided for
herein, or (ii) action, suit, arbitration, litigation, investigation or
proceeding of or before any arbitrator or Governmental Authority pending against
Pledgor or, to Pledgor's knowledge, threatened against Pledgor which would
reasonably be expected to materially adversely affect the right or ability of
Pledgor to fulfill its obligations under this Agreement.

       (o)    Pledgor has, independently and without reliance upon the
Administrative Agent and based on such documents and information as it has
deemed appropriate, made its own credit analysis and decision to enter into this
Agreement.

                                       5
<PAGE>   252

       SECTION 8. Further Assurances. (a) Pledgor agrees that from time to time,
at the expense of Pledgor, Pledgor will promptly execute and deliver all further
instruments and documents, and take all further action, that may be necessary,
or that the Administrative Agent may reasonably request, in order to perfect and
protect the pledge, assignment, hypothecation and security interest granted or
purported to be granted hereby or to enable the Administrative Agent to exercise
and enforce its rights and remedies hereunder with respect to any Collateral.
Without limiting the generality of the foregoing, Pledgor will (i) execute and
file such financing or continuation statements, or amendments thereto, and such
other instruments or notices, as may be necessary, or as the Administrative
Agent may reasonably request, in order to perfect and preserve the assignment,
hypothecation and security interest granted or purported to be granted hereby;
and (ii) mark conspicuously, at the request of the Administrative Agent, each of
its records pertaining to the Collateral with a legend, in form and substance
satisfactory to the Administrative Agent, indicating that the Partnership
Agreements and such chattel paper have been assigned and are subject to the
security interest pursuant hereto.

       (b)    Pledgor hereby further authorizes the Administrative Agent to file
one or more financing or continuation statements, and amendments thereto,
relative to all or any part of the Collateral without the signature of Pledgor
where permitted by law. A photocopy or other reproduction of this Agreement or
any financing statement covering the Collateral or any part thereof shall be
sufficient as a financing statement where permitted by law.

       SECTION 9. Voting Rights; Distributions, Etc. (a) So long as no Event of
Default shall have occurred and be continuing, but subject, nevertheless, at all
times to the restrictions imposed by Section 6.10 of the Credit Agreement and by
subsection (b) below, Pledgor shall be entitled to receive free and clear of the
interest of the Administrative Agent granted under this Agreement all payments
and other distributions receivable by it under any Partnership Agreement that
are Distributions expressly permitted by the Deposit Account Agreement and the
Credit Agreement, and shall be entitled to exercise any and all management,
voting and other partnership rights pertaining to any Collateral including but
not limited to any partnership interest or Partnership Agreement and the
Borrower Entities for any purpose not inconsistent with the terms of this
Agreement or any other Financing Document; provided, however, that Pledgor shall
exercise, or refrain from exercising, any such right if such action or inaction
would have a material adverse effect on the attachment, perfection, creation or
priority of the security interest in the Collateral or any part thereof as
herein granted.

       (b)    Pledgor's right to receive and retain any and all distributions in
respect of the Collateral purported to be pledged and assigned by it hereunder
shall be further limited as follows:

              (i)    distributions other than in cash in respect of, and
              instruments and other property received, receivable or otherwise
              distributed in respect of, or in exchange for, any such
              Collateral, and

              (ii)   distributions paid or payable in cash in respect of any
              such Collateral in connection with a partial or total
              liquidation or dissolution of any of the Borrower Entities,

                                       6
<PAGE>   253

shall be, and shall be forthwith delivered to the Administrative Agent to hold
as, Collateral and shall, if received by Pledgor, be received in trust for the
benefit of the Administrative Agent, be segregated from the other property or
funds of Pledgor and be forthwith delivered to the Administrative Agent as
Collateral in the same form as so received (with any necessary endorsement or
assignment).

       (c)    Upon the occurrence and during the continuance of an Event of
Default:

              (i)    Immediately upon Pledgor's receipt of written notice from
              the Administrative Agent that the Administrative Agent intends to
              act pursuant to this clause (c)(i), all rights of Pledgor to
              exercise or refrain from exercising the voting and other
              consensual rights which it would otherwise be entitled to exercise
              shall thereupon become exercisable by the Administrative Agent,
              acting in good faith, who shall have the sole right to exercise or
              refrain from exercising such voting and other consensual rights
              unless and until such Event of Default ceases to exist.

              (ii)   All rights of Pledgor to receive the distributions which it
              would otherwise be authorized to receive and retain, pursuant to
              Section 9(a) and (b), above, shall become exercisable by the
              Administrative Agent who shall thereupon have the sole right to
              receive and hold as Collateral such distributions unless and until
              such Event of Default ceases to exist.

              (iii)  All distributions which are received by Pledgor contrary to
              the provisions of clause (ii), above, shall be received in trust
              for the benefit of the Administrative Agent, shall be segregated
              from other funds of Pledgor and shall be forthwith paid over to
              the Administrative Agent as Collateral in the same form as so
              received (with any necessary endorsement) for application pursuant
              to Section 17.

       SECTION 10. Place of Perfection; Records. Pledgor shall keep its place of
business and chief executive office and the office where it keeps its records
concerning the Collateral, and original copies of each Partnership Agreement and
of all other chattel paper which evidence the Collateral, at its address
specified on the signature pages hereof; or, upon 30 days' prior written notice
to the Administrative Agent, at such other location in a jurisdiction where all
action required by Section 8 shall have been taken with respect to the
Collateral. Pledgor will hold and preserve such records and will permit
representatives of the Administrative Agent at any time, upon reasonable prior
notice, during normal business hours to inspect and make abstracts from such
records.

       SECTION 11. As to the Partnership Agreements. (a) Pledgor shall at its
expense perform and observe all the terms and provisions to be performed or
observed by it under each Partnership Agreement, maintain each Partnership
Agreement in full force and effect, enforce each Partnership Agreement in
accordance with its terms, and take all such action to such end as may be from
time to time reasonably requested by the Administrative Agent.

       (b)    Pledgor shall not:

                                       7
<PAGE>   254

              (i)    sell, assign (by operation of law or otherwise) or
              otherwise dispose of any of the Collateral, or create or suffer to
              exist any Lien upon or with respect to any of the Collateral,
              except for the pledge, assignment, hypothecation and security
              interest created by this Agreement and Permitted Liens;

              (ii)   cancel or terminate any Partnership Agreement or consent to
              or accept any cancellation or termination thereof;

              (iii)  amend or otherwise modify in a material respect any
              Partnership Agreement; or

              (iv)   waive any material default under or material breach of any
              Partnership Agreement.

       SECTION 12. Covenants. Pledgor covenants and agrees that so long as any
Lender shall have any Commitment outstanding and until the Notes, together with
interest, and all other Secured Obligations are indefeasibly paid in full,
unless the Administrative Agent shall otherwise consent in writing, Pledgor:

       (a)    Maintenance of Register. Will cause each Borrower Entity to
maintain at all times a register at its chief place of business and chief
executive office in which the security interest in the Collateral granted hereby
to the Administrative Agent, to the extent that the same constitutes
"uncertificated securities" (as defined in the Delaware UCC), shall be
evidenced.

       (b)    Preservation of Existence, Etc. Will preserve and maintain, and
will cause each Borrower Entity to preserve and maintain, its lawful existence,
rights (charter and statutory), and franchises.

       (c)    Compliance with Law. Will comply with all material Requirements of
Law and material Governmental Approvals applicable to it, except when any such
Requirement of Law or Governmental Approval is being contested in good faith and
by appropriate proceedings and for which Acceptable Reserves have been
established.

       (d)    Change in Nature of Business. Will not engage in any business
other than being a general partner of the Borrower Entities.

       (e)    Jurisdiction of Organization. Will cause each Borrower Entity at
all times to be a limited partnership organized under the laws of the State of
Delaware.

       (f)    Bankruptcy. Will not file a voluntary petition or otherwise
initiate proceedings to have any Borrower Entity adjudicated bankrupt or
insolvent, or consent to the institution of bankruptcy or insolvency proceedings
against any Borrower Entity, or file a petition seeking or consenting to
reorganization or relief of any Borrower Entity as debtor under any applicable
federal or state law relating to bankruptcy, insolvency, or other relief for
debtors with respect to any Borrower Entity; or seek or consent to the
appointment of any trustee,

                                       8
<PAGE>   255

receiver, conservator, assignee, sequestrator, custodian, liquidator (or other
similar official) of any Borrower Entity or of all or any substantial part of
the properties and assets of any Borrower Entity, or make any general assignment
for the benefit of creditors of any Borrower Entity, or admit in writing the
inability of any Borrower Entity to pay its debts generally as they become due
or declare or effect a moratorium on the debt of any Borrower Entity or take any
action in furtherance of any action;

       (g)    Taxes. Will pay and discharge or cause to be paid or discharged
all taxes, assessments and governmental charges or levies lawfully imposed upon
it, any Borrower Entity or upon any of their respective income or profits or
upon any of the Portfolio Assets or the Collateral and all lawful claims or
obligations that, if unpaid, would become a Lien upon the Collateral (as defined
in the Credit Agreement), whether real or personal, the Collateral (as defined
in this Agreement) or upon any part thereof. The Pledgor shall have the right,
however, to contest in good faith the validity or amount of any such tax,
assessment, charge or levy by proper proceedings, and may permit the taxes,
assessments, charges or levies so contested to remain unpaid during the period
of such contest if: (a) the Pledgor diligently prosecutes such contest in good
faith and by appropriate proceedings and has established Acceptable Reserves;
(b) during the period of such contest, the enforcement of any contested item is
effectively stayed; and (c) the failure to pay or comply with the contested item
could not reasonably be expected to result in a material adverse effect on the
Collateral.

       (h)    Operations Matters. Will conduct its business and operations, and
will cause each Borrower Entity to conduct its business and operations, in
accordance with the following provisions:

              (i)    maintain books and records, separate from those of any
       other Person;

       entity separate and distinct from any other Person;

<PAGE>   256
              (viii) conduct business in its own name;

       business operations.

       (i)    Assets. Will not own or acquire any asset other than the
Collateral and Distributions permitted by the Financing Documents.

       (j)    Indebtedness. Will not incur Indebtedness other than Permitted
Indebtedness (in its capacity as the general partner of the Borrower Entities.).

       SECTION 13. Administrative Agent. Bank of America, N.A. has been
appointed by the Secured Parties to act as the Administrative Agent hereunder.
Pledgor hereby appoints the Administrative Agent as Pledgor's attorney-in-fact,
with full authority in the place and stead of Pledgor and in the name of Pledgor
or otherwise, from time to time in the Administrative Agent's discretion at any
time that an Event of Default shall have occurred and be continuing, to take any
action and to execute any instrument which the Administrative Agent may deem
necessary or advisable to accomplish the purposes of this Agreement, including,
without limitation, to ask, demand, collect, sue for, recover, compound, receive
and give acceptance and receipts for moneys due and to become due under or in
connection with the Collateral, to receive, indorse, and collect any drafts or
other instruments, documents and chattel paper in connection therewith, and to
file any claims or take any action or institute any proceedings which the
Administrative Agent may deem to be necessary or desirable for the collection
thereof or to enforce compliance with the terms and conditions of any
Partnership Agreement. Such appointment is coupled with an interest and is
irrevocable.

       SECTION 14. Administrative Agent May Perform. If Pledgor fails to perform
any agreement contained herein, the Administrative Agent may itself perform, or
cause performance of, such agreement, and the expenses of the Administrative
Agent incurred in connection therewith shall be payable by Pledgor under Section
20(b).

       SECTION 15. The Administrative Agent's Duties. The powers conferred on
the Administrative Agent hereunder are solely to protect its interest in the
Collateral and shall not impose any duty upon it to exercise any such powers.
Except for the safe custody of any Collateral in its possession and the
accounting for moneys actually received by it hereunder, the Administrative
Agent shall have no duty as to any Collateral or as to the taking of any
necessary steps to preserve rights against prior parties or any other rights
pertaining to any Collateral and no such duties shall be implied as arising
hereunder.

                                       10
<PAGE>   257

       SECTION 16. Remedies. If any Event of Default shall have occurred and be
continuing, subject to Section 9 and compliance with Requirements of Law:

       (a)    The Administrative Agent may exercise any and all rights and
remedies of Pledgor under or in connection with any Partnership Agreement, the
Partnership Interests or otherwise in respect of the Collateral, including,
without limitation, any and all rights of Pledgor to demand or otherwise require
payment of any amount under, or performance of any provision of, any Partnership
Agreement and all rights of Pledgor to control the operation of the Borrower
Entities.

       (b)    All payments received by Pledgor under or in connection with any
Partnership Agreement, the Partnership Interests, or otherwise in respect of the
Collateral shall be received in trust for the benefit of the Administrative
Agent, shall be segregated from other funds of Pledgor and shall be forthwith
paid over to the Administrative Agent in the same form as so received (with any
necessary endorsement).

       (c)    Any Collateral repossessed by the Administrative Agent under or
pursuant to this Section 16 or any other provision hereof, and any other
Collateral whether or not so repossessed by the Administrative Agent, may be
sold, assigned, leased or otherwise disposed of under one or more contracts or
as an entirety, and without the necessity of gathering at the place of sale the
property to be sold, and in general in such manner, at such time or times, at
such place or places and on such terms as the Administrative Agent may, upon
written direction in compliance with any mandatory requirements of any
Requirement of Law, determine to be commercially reasonable. Any such
disposition which shall be a private sale or other private proceeding permitted
by such requirements shall be made upon not less than 10 days' written notice to
Pledgor specifying the time at which such disposition is to be made and the
intended sale price or other consideration therefor, and shall be subject, for
the 10 days after the giving of such notice, to the right of the Pledgor or any
nominee of Pledgor to acquire the Collateral involved at a price or for such
other consideration at least equal to the intended sale price or other
consideration so specified. To the extent permitted by Requirements of Law, the
Administrative Agent on behalf of the Lenders may bid for and become the
purchaser of the Collateral or any item thereof, offered for sale in accordance
with this Section 16. If, under mandatory requirements of any Requirement of
Law, the Administrative Agent shall be required to make disposition of the
Collateral within a period of time which does not permit the giving of notice to
Pledgor as hereinabove specified, the Administrative Agent need give Pledgor
only such notice of disposition as shall be reasonably practicable in view of
such mandatory requirements of any Requirement of Law.

       (d)    All payments made under or in connection with, or proceeds
realized from, any Partnership Agreement, the Partnership Interests, or
otherwise in respect of the Collateral and received by the Administrative Agent
shall be applied in whole or in part by the Administrative Agent against, all or
any part of the Secured Obligations in accordance with the terms of the Deposit
Account Agreement. Any surplus of such payments held by the Administrative Agent
and remaining after payment in full of all the Secured Obligations shall be paid
over to Pledgor or to whomsoever else may be lawfully entitled to receive such
surplus.

COLLATERAL, IN EACH CASE AS PERMITTED BY APPLICABLE REQUIREMENTS OF LAW,

       acting on its behalf or instruction;

              (ii)   all other requirements as to the time, place and terms of
       sale or other requirements with respect to the enforcement of the
       Administrative Agent's rights hereunder; and

              (iii)  all rights of redemption, appraisement, valuation, stay,
       extension or moratorium now or hereafter in force under any Requirements
       of Law in order to prevent or delay the enforcement of this Agreement
       (including, without limitation, any right to claim that such enforcement
       should be stayed pending the outcome of any other action or proceeding
       (including any arbitration proceeding)) or the absolute sale of the
       Collateral or any portion thereof, and Pledgor, for itself and all who
       may claim under it, insofar as it or they now or hereafter lawfully may,
       hereby waives the benefit of all such Requirements of Law.

Any sale of, or the grant of options to purchase, or any other realization upon,
any Collateral shall, to the extent permitted by Requirements of Law, operate to
divest all right, title, interest, claim and demand, either at law or in equity,
of Pledgor therein and thereto, and shall be a perpetual bar both at law and in
equity against Pledgor and against any and all Persons claiming or attempting to
claim the Collateral so sold, optioned or realized upon, or any part thereof,
from, through and under Pledgor.

       SECTION 17. Application of Proceeds. Notwithstanding any other provision
of this Agreement, all moneys collected by the Administrative Agent upon any
sale or other disposition of the Collateral pursuant to Section 16, together
with all other moneys received by the Administrative Agent hereunder, shall be
applied in accordance with the Deposit Account Agreement.

       SECTION 18. Remedies Cumulative. No failure or delay on the part of the
Administrative Agent or any Secured Party in exercising any right, power or
privilege hereunder or under any other Financing Document and no course of
dealing between Pledgor and the Administrative Agent or any Secured Party shall
operate as a waiver thereof; nor shall any single or partial exercise of any
right, power or privilege hereunder or under any other Financing

                                       12
<PAGE>   259

Document preclude any other or further exercise thereof or the exercise of any
other right, power or privilege hereunder or thereunder. The rights, powers and
remedies herein or in any other Financing Document expressly provided are
cumulative and not exclusive of any rights, powers or remedies which the
Administrative Agent or any Secured Party would otherwise have. No notice to or
demand on Pledgor in any case shall entitle Pledgor to any other or further
notice or demand in similar or other circumstances or constitute a waiver of the
rights of the Administrative Agent or any Secured Party to any other or further
action in any circumstances without notice or demand.

       SECTION 19. Discontinuance of Proceedings. In case the Administrative
Agent shall have instituted any proceeding to enforce any right, power or remedy
under this Agreement by foreclosure, sale or otherwise, and such proceeding
shall have been discontinued or abandoned for any reason or shall have been
determined adversely to the Administrative Agent, then and in every such case
Pledgor, the Administrative Agent and each holder of any of the Secured
Obligations shall be restored to their former positions and rights hereunder
with respect to the Collateral subject to the security interest created under
this Agreement, and all rights, remedies and powers of the Administrative Agent
shall continue as if no such proceeding had been instituted.

       SECTION 20. Indemnity and Expenses. (a) Pledgor agrees to indemnify and
hold harmless the Administrative Agent and each Secured Party from and against
any and all claims, losses and liabilities arising out of or resulting from the
Collateral or Pledgor's pledge and assignment under this Agreement (including,
without limitation, enforcement against Pledgor of this Agreement), except
claims, losses or liabilities resulting from the Administrative Agent's or any
Secured Party's gross negligence or willful misconduct.

       (b)    Pledgor will upon demand pay to the Administrative Agent or any
Secured Party the amount of any and all reasonable expenses, including the
reasonable fees and expenses of its counsel and of any experts and agents, which
the Administrative Agent or any Secured Party may incur in connection with (i)
the administration of this Agreement, (ii) the sale of, collection from, or
other realization upon, any of the Collateral of Pledgor, (iii) the exercise or
enforcement (whether through negotiations, legal proceedings or otherwise) of
any of the rights of the Administrative Agent or any Secured Party hereunder
against Pledgor or (iv) the failure by Pledgor to perform or observe any of the
provisions hereof.

       SECTION 21. Security Interest Absolute. The obligations of Pledgor under
this Agreement are independent of the Secured Obligations, and a separate action
or actions may be brought and prosecuted against Pledgor to enforce this
Agreement, irrespective of whether any action is brought against the Borrower,
any other pledgor or any guarantor of the Secured Obligations or whether the
Borrower, any other pledgor or any guarantor of the Secured Obligations is
joined in any such action or actions. All rights of the Administrative Agent and
the assignment, hypothecation and security interest hereunder, and all
obligations of Pledgor hereunder, shall be absolute and unconditional, to the
extent permitted by applicable law, irrespective of:

                                       13
<PAGE>   260

       (a)    any lack of validity or enforceability of this Agreement, the
Credit Agreement, any other Financing Document or any other agreement or
instrument relating to any thereof, the absence of any action to enforce the
same, any release of any Borrower Entity or Pledgor, the recovery of any
judgment against any Borrower Entity or Pledgor, any action to enforce the same
or any other circumstance which might otherwise constitute a legal or equitable
discharge or defense of Pledgor;

       (b)    any occurrence or condition whatsoever, including without
limitation, (i) any compromise, settlement, release, waiver, renewal, extension,
indulgence or modification of, or any change in, any of the obligations of any
Borrower Entity or Pledgor contained in this Agreement, the Credit Agreement or
any other Financing Document, (ii) any impairment, modification, release or
limitation of the liability of any Borrower Entity or Pledgor or any of their
estates in bankruptcy, or any remedy for the enforcement thereof, resulting from
the operation of any present or future provision of any applicable bankruptcy
law, as amended, or other statute or from the decision of any court, (iii) the
assertion or exercise by Pledgor, the Administrative Agent or any other Secured
Party of any rights or remedies, (iv) the assignment or the purported assignment
of any property as security for the Secured Obligations, including all or any
part of the rights of Pledgor under this Agreement, (v) the extension of the
time for payment by any Borrower Entity or any other guarantor of any payments
or other sums or any part thereof owing or payable under any of the terms and
provisions of any Financing Document or of the time for performance by any
Borrower Entity or Pledgor of any other obligations under or arising out of any
terms or provisions or the extension of the renewal of any thereof, (vi) the
modification or amendment (whether material or otherwise) of any duty, agreement
or obligation of any Borrower Entity or Pledgor set forth in any Financing
Document, (vii) the voluntary or involuntary liquidation, dissolution, sale or
other disposition of all or substantially all of the assets, marshalling of
assets and liabilities, receivership, insolvency, bankruptcy, assignment for the
benefit of creditors, reorganization, arrangement, composition or readjustment
of, or other similar proceeding affecting any Borrower Entity or Pledgor or any
of their respective assets, or the disaffirmancy of this Agreement or any
Financing Document in any such proceeding, (viii) the release or discharge of
any Borrower Entity or Pledgor from the performance or observance of any
agreement, covenant, term or condition contained in any of such instruments by
operation of law, (ix) the unenforceability of this Agreement or any Financing
Document or (x) any other circumstance which might otherwise constitute a legal
or equitable discharge of a surety or guarantor; or

       (c)    any exchange, release or non-perfection of any collateral, or any
release or amendment or waiver of or consent to departure from any other
guarantee, for all or any of the Secured Obligations.

       SECTION 22. Amendment; Waiver. No amendment or waiver of any provision of
this Agreement shall be effective unless the same shall be undertaken and
accomplished in accordance with the requirements of Section 9.02 of the Credit
Agreement. No delay on the part of any Secured Party in the exercise of any
right, power or remedy shall operate as a waiver thereof, nor shall any single
or partial waiver by such Secured Party of any right, power or remedy preclude
any further exercise thereof, or the exercise of any other right, power or
remedy.

<PAGE>   261

       SECTION 23. Addresses for Notices. All notices, requests and other
communications to Pledgor or the Administrative Agent shall be in writing
(including bank wire, cable, telex, telecopy or similar teletransmission or
writing) and shall be given, in the case of Pledgor to its address, or telex,
cable or telecopy number set forth on the signature page hereof, and in the case
of the Administrative Agent, to it at its address, or telex, cable or telecopy
number set forth in Annex II to the Credit Agreement or such other address or
telex, cable or telecopy number as each party may hereafter specify by notice to
such other party. Each such notice, request or other communication shall be
effective (i) if given by telex, when such telex is transmitted to the telex
number specified on the signature page hereof or in Annex II, as the case may
be, and the appropriate answerback is received, (ii) if given by telecopy, when
such telecopy is transmitted to the telecopy number specified on the signature
page hereof or in Annex II, as the case may be, and receipt thereof is confirmed
in writing, or (iii) if given by any other means (including, without limitation,
by air courier), when delivered at the address specified on the signature page
hereof or in Annex II, as the case may be.

       SECTION 24. Continuing Assignment, Pledge and Security Interest, Transfer
of Note. This Agreement shall create a continuing pledge, assignment of,
hypothecation of and security interest in the Collateral and shall (i) remain in
full force and effect until no Lender shall have any Commitment outstanding, and
until the Notes, together with interest, and all other Secured Obligations are
indefeasibly paid in full, (ii) be binding upon Pledgor, its successors and
assigns, provided, that Pledgor may not transfer or assign any or all of its
rights or obligations hereunder without the prior written consent of each
Lender, and (iii) inure to the benefit of, and be enforceable by, the
Administrative Agent, the Secured Parties and their respective successors,
transferees and assigns. Without limiting the generality of the foregoing clause
(iii), any Secured Party may assign or otherwise transfer all or any portion of
its rights in the Secured Obligations to the extent and in the manner provided
in the Credit Agreement, and such assignee shall thereupon become vested with
all the benefits in respect thereof granted to such Secured Party herein or
otherwise. Upon the indefeasible payment in full of the Secured Obligations and
the expiration or termination of the Commitments, the security interest granted
hereby shall terminate and all rights to the Collateral shall revert to Pledgor.
Upon any such termination, the Administrative Agent will, at Pledgor's expense,
execute and deliver to Pledgor such documents including UCC termination
statements as Pledgor shall reasonably request to evidence such termination.

       SECTION 25. Severability. Any provision hereof that is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof and without affecting the validity or enforceability
of any provision in any other jurisdiction.

       SECTION 26. GOVERNING LAW; TERMS. THIS AGREEMENT SHALL BE GOVERNED BY AND
INTERPRETED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK OTHER THAN ANY
SUCH REQUIREMENT OF LAWS THAT WOULD APPLY THE LAWS OF ANOTHER JURISDICTION,
EXCEPT TO THE EXTENT THAT THE LAWS OF ANOTHER JURISDICTION ARE MANDATORILY
APPLICABLE AND EXCEPT TO THE EXTENT THAT THE VALIDITY OR PERFECTION OF THE
SECURITY INTEREST HEREUNDER, OR REMEDIES HEREUNDER, IN RESPECT OF

                                       15
<PAGE>   262

ANY PARTICULAR COLLATERAL ARE GOVERNED BY THE LAWS OF A JURISDICTION OTHER THAN
THE STATE OF NEW YORK. UNLESS OTHERWISE DEFINED HEREIN OR IN THE CREDIT
AGREEMENT, TERMS USED IN ARTICLE 9 OF THE NY UCC ARE USED HEREIN AS THEREIN
DEFINED. ANY DISPUTE ARISING OUT OF, CONNECTED WITH, RELATED TO, OR INCIDENTAL
TO THE RELATIONSHIP ESTABLISHED BETWEEN THE PLEDGOR AND EACH SECURED PARTY IN
CONNECTION WITH THIS AGREEMENT AND THE OTHER FINANCING DOCUMENTS, AND WHETHER
ARISING IN CONTRACT, TORT, EQUITY OR OTHERWISE, SHALL BE RESOLVED IN ACCORDANCE
WITH THE INTERNAL LAWS (AS OPPOSED TO THE CONFLICTS OF LAWS PROVISIONS) AND
DECISIONS OF THE STATE OF NEW YORK.

       SECTION 27. CONSENT TO JURISDICTION; WAIVER OF JURY TRIAL. (a) PLEDGOR
AND EACH SECURED PARTY AGREE THAT ALL DISPUTES BETWEEN THEM ARISING OUT OF,
CONNECTED WITH, RELATED TO, OR INCIDENTAL TO THE RELATIONSHIP ESTABLISHED
BETWEEN THEM IN CONNECTION WITH THIS AGREEMENT AND THE OTHER FINANCING
DOCUMENTS, AND WHETHER ARISING IN CONTRACT, TORT, EQUITY, OR OTHERWISE, SHALL BE
RESOLVED ONLY BY STATE OR FEDERAL COURTS LOCATED IN NEW YORK, NEW YORK, BUT
PLEDGOR AND EACH SECURED PARTY ACKNOWLEDGE THAT ANY APPEALS FROM THOSE COURTS
MAY HAVE TO BE HEARD BY A COURT LOCATED OUTSIDE OF NEW YORK, NEW YORK. PLEDGOR
WAIVES IN ALL DISPUTES ANY OBJECTION THAT IT MAY HAVE TO THE LOCATION OF THE
COURT CONSIDERING THE DISPUTE INCLUDING, WITHOUT LIMITATION, ANY OBJECTION TO
THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS.

PARTICIPATE IN RESOLVING ANY DISPUTE, WHETHER SOUNDING IN CONTRACT, TORT, OR

RELATIONSHIP ESTABLISHED BETWEEN THEM IN CONNECTION WITH THIS AGREEMENT AND THE
OTHER FINANCING DOCUMENTS. INSTEAD, ANY DISPUTES RESOLVED IN COURT WILL BE
RESOLVED IN A BENCH TRIAL WITHOUT A JURY.

       SECTION 28. Execution in Counterparts. This Agreement may be executed in
any number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed shall be deemed to be an original
and all of which taken together shall constitute one and the same instrument.

       SECTION 29. Limitation on Recourse. The obligations of Pledgor hereunder
are obligations solely of Pledgor and shall not constitute a debt or obligation
of any direct or indirect partner or shareholder of Pledgor or any of their
respective directors, officers, agents or employees (each such Person, a
"Non-Recourse Party"). No Non-Recourse Party shall be liable for any amount
payable by Pledgor under this Agreement and the Secured Parties shall not seek a
money judgment or deficiency or personal judgment against any Non-Recourse Party
for payment of the indebtedness payable by Pledgor evidenced by this Agreement.
No property or assets of any Non-Recourse Party, other than as contemplated in
the Financing Documents, shall

                                       16
<PAGE>   263

be sold, levied upon or otherwise used to satisfy any judgment rendered in
connection with any action brought against Pledgor with respect to this
Agreement or the other Financing Documents. The foregoing acknowledgments,
agreements and waivers shall be enforceable by any Non-Recourse Party.
Notwithstanding the foregoing, nothing in this Section shall limit or affect or
be construed to limit or affect the obligations and liabilities of any Credit
Party or any other Non-Recourse Party (a) in accordance with the terms of any
Transaction Document or Financing Document creating such liabilities and
obligations to which such Credit Party or Non-Recourse Party is a party, (b)
arising from liability pursuant to applicable Requirements of Law for such
Credit Party's or such Non-Recourse Party's fraudulent actions, knowing
misrepresentations or willful misconduct or (c) with respect to amounts
distributed to it in violation of Section 6.10 of the Credit Agreement.

Bank of America, N.A., as Issuing Bank and the Lenders named on the signature

meanings attributed to them in the Credit Agreement), pursuant to which the
Lenders have agreed, inter alia, to make available credit facilities to the
Pledgor to finance a portion of the purchase price of the Portfolio Assets and
to provide working capital availability to the Pledgor;

       WHEREAS, the Credit Agreement contemplates the execution, delivery and

       (a)    All general and limited partnership interests now owned or
hereafter acquired by Pledgor in and to each Operating Company (collectively,
the "Partnership Interests") and the partnership agreements relating to each
Operating Company (collectively, the "Partnership Agreements") and all rights
related thereto, including, without limitation, (i) all rights of Pledgor as a
general or limited partner, as the case may be, and all rights to receive
distributions, cash, instruments and other property from time to time receivable
or otherwise distributable in respect of any Partnership Interest or pursuant to
any Partnership Agreement, (ii) all rights of Pledgor to receive proceeds of any
insurance, indemnity, warranty or guaranty with respect to any Partnership
Interest or any Partnership Agreement, (iii) all claims of Pledgor for damages
arising out of or for breach of or default under any Partnership Agreement, (iv)
the right of Pledgor to terminate any Partnership Agreement, to perform and
exercise consensual or voting rights thereunder and to compel performance and
otherwise exercise all remedies thereunder, (v) all rights of Pledgor as a
general or limited partner of any of the Operating Companies, to any property
and assets of the Operating Companies (whether real property, inventory,
equipment, contract rights, accounts, receivables, general intangibles,
securities, instruments, chattel paper, documents, chooses in action or
otherwise), and (vi) all certificates or instruments evidencing an ownership or
partnership interest in the Operating Companies or their assets; and

       (b)    to the extent not included in the foregoing, all proceeds of any
and all of the foregoing (including, without limitation, proceeds that
constitute property of the types described above).

       SECTION 2. Security for Secured Obligations. This Agreement secures the
prompt and complete payment and performance of all of the Obligations (as
defined in the Credit Agreement) of the Pledgor now or hereafter existing under
the Financing Documents, when and as the same shall become due and payable
(whether by acceleration or otherwise) in accordance with the terms thereof
(collectively, the "Secured Obligations"). Without limiting the generality of
the foregoing, this Agreement secures the payment of all amounts which
constitute part of the Secured Obligations and would be owed by the Pledgor to
the Secured Parties but for the fact that they are unenforceable or not
allowable due to the existence of a bankruptcy, reorganization or similar
proceeding involving any Credit Party.

       SECTION 3. Pledgor Remains Liable. Anything herein to the contrary
notwithstanding, (a) Pledgor shall remain liable under each Partnership
Agreement and the other contracts and agreements included in the Collateral to
the extent set forth therein to perform all of its duties and obligations
thereunder to the same extent as if this Agreement had not been executed, (b)
the exercise by any Secured Party of any of the rights hereunder shall not
release Pledgor from any of its duties or obligations under the contracts and
agreements included in the Collateral and (c) neither the Administrative Agent
nor any Secured Party shall have any obligation or liability under the contracts
and agreements included in the Collateral or otherwise by reason of this
Agreement, nor shall the Administrative Agent or any Secured Party be obligated
to perform any of the obligations or duties of Pledgor thereunder or to take any
action to collect or enforce any claim assigned hereunder.

       SECTION 4. Delivery of Collateral. All certificates or instruments
representing or evidencing the Collateral at any time shall be delivered to and
held by or on behalf of the Administrative Agent pursuant hereto and shall be in
suitable form for transfer by delivery, or shall be accompanied by duly executed
instruments of transfer or assignment in blank, all in form and substance
satisfactory to the Administrative Agent. The Administrative Agent shall have
the right, upon the occurrence and continuance of an Event of Default, in its
discretion and without notice to Pledgor, to transfer to or to register in the
name of the Administrative Agent or any of its nominees any or all of the
Collateral, subject only to compliance with Requirements of Law, the terms and
conditions of the Credit Agreement and the revocable rights specified in Section
9(a). In addition, the Administrative Agent shall have the right at any time to
exchange certificates or instruments representing or evidencing Collateral for
certificates or instruments of smaller or larger denominations.

       SECTION 5. [intentionally omitted].

       SECTION 6. Reinstatement. This Agreement shall continue to be effective,
or be reinstated, as the case may be, if at any time payment, or any part
thereof, of any of the Secured Obligations is rescinded or must otherwise be
restored or returned by any Secured Party upon the insolvency, bankruptcy,
dissolution, liquidation or reorganization of Pledgor, or upon or as a result of
the appointment of a receiver, intervenor or conservator of, or trustee or
similar officer for, Pledgor or any substantial part of its property, or
otherwise, all as though such payments had not been made.

       SECTION 7. Representations and Warranties. Pledgor represents and
warrants as follows:

       (a)    Pledgor (i) is duly formed, validly existing and in good standing
under the laws of the State of Delaware, (ii) has all requisite power and
authority to own its property and assets, to borrow money and to transact the
business in which it is presently engaged and in which it proposes to be
engaged, (iii) has duly qualified and is authorized to do business and is in
good standing in every jurisdiction where the character of its properties or the
nature of its activities makes such qualification necessary and (iv) is in full
compliance with its Governing Documents, all material Contractual Obligations,
all applicable material Requirements of Law and all material Governmental
Approvals. As of the date hereof; (x) the Operating Companies are the only
Subsidiaries of the Pledgor; and (y) Pledgor is the sole Limited Partner of each
Operating Company.

       (b)    The execution, delivery and performance by Pledgor of this
Agreement and the consummation of the transactions contemplated hereby (i) are
within its powers, (ii) have been duly authorized by all necessary partnership
action, (iii) do not and will not contravene (A) its Governing Documents or (B)
any material Requirement of Law, any material Contractual Obligation or any
material Governmental Approval binding on or affecting it and (iv) does not and
will not conflict with or be inconsistent with or result in any breach of any of
the material terms, covenants, conditions or provisions of, or constitute a
default under, or result in the creation or imposition of (or the obligation to
create or impose) any Lien (except Permitted

                                       3
<PAGE>   272

Liens) upon any of its properties or assets pursuant to, the terms of any
material Contractual Obligation binding on or affecting it.

       (c)    Pledgor has duly executed and delivered this Agreement and this
Agreement constitutes the legal, valid and binding obligation of Pledgor,
enforceable against Pledgor in accordance with its terms, except as enforcement
thereof may be subject to (i) the effect of any applicable bankruptcy,
insolvency, reorganization, moratorium or similar laws affecting creditors'
rights generally and (ii) general principles of equity.

       (d)    No Governmental Approval or approval of any other Person (except
such as have been duly obtained, made or given, and are in full force and
effect) is required to authorize, or is required in connection with (i) the
execution, delivery or performance of this Agreement by Pledgor or the
consummation of any of the transactions contemplated hereby, (ii) the legality,
validity, binding effect or enforceability of this Agreement or the perfection
and maintenance of the security interest created hereby (including the first
priority nature of such security interest) or (iii) for the exercise by the
Administrative Agent of the voting or other rights provided for in this
Agreement or the remedies in respect of the Collateral pursuant to this
Agreement. All applicable waiting periods relating to any such Governmental
Approval or other approval which are required and have been obtained have
expired without any adverse action taken with respect thereto.

       (e)    Each Partnership Agreement, true and complete copies of which have
been furnished to the Administrative Agent, has been duly authorized, executed
and delivered by Pledgor and is in full force and effect and is binding upon and
enforceable against Pledgor in accordance with its terms. There exists no
default under any Partnership Agreement.

       (f)    This Agreement creates a valid security interest in the Collateral
purported to be pledged and assigned by Pledgor hereunder securing the payment
of the Secured Obligations.

       (g)    Upon the filing of the financing statements (the "Financing
Statements") referenced in Schedule I hereof under the Uniform Commercial Code
as in effect in the State of Delaware (the "Delaware UCC"), the security
interest is created hereby shall be perfected under the Delaware UCC, to the
extent that the Collateral constitutes "general intangibles" (as defined in the
Delaware UCC) and no further filings or other actions are necessary to perfect
such security interest. Upon filing of such Financing Statements pursuant to the
Delaware UCC, such security interests, as so perfected, are first priority
security interests.

       (h)    When any certificates or instruments evidencing the Collateral
shall be delivered hereunder, and for so long as such certificates or
instruments shall remain in the possession of the Administrative Agent in the
State of New York or the State of North Carolina, the security interest in such
Collateral created hereby shall be perfected under the Uniform Commercial Code
as in effect in the State of New York (the "NY UCC") or the State of North
Carolina, as applicable, and such security interest, as so perfected, will be a
first priority security interest.

       (i)    The security interest created by this Agreement in the Collateral
described in clause (a) of Section 1 hereof has been registered in the name of
the Administrative Agent in the register maintained for such purpose at the
chief executive office and principal place of business

                                       4
<PAGE>   273

of each Operating Company, as applicable, and, to the extent that such
Collateral constitutes "uncertificated securities" (as defined in the Delaware
UCC), such security interest is perfected under the Delaware UCC and, as so
perfected, is a first priority security interest.

       (j)    The chief place of business and chief executive office of Pledgor
and the office where Pledgor keeps its records concerning the Collateral is set
forth under its name on the signature page hereof.

       (k)    Pledgor is the legal and beneficial owner of the Collateral
purported to be pledged and assigned by it hereunder, free and clear of any
Lien, other than Permitted Liens. No effective financing statement or other
instrument similar in effect covering all or any part of such Collateral has
been executed or authorized by Pledgor or, is on file in any recording office,
except such as may have been filed in favor of the Administrative Agent relating
to this Agreement. Pledgor has no trade name.

       (l)    There are no conditions precedent to the effectiveness of this
Agreement that have not been satisfied or waived.

       (m)    No part of the Collateral is subject to the terms of any agreement
restricting the sale or transfer of such Collateral, except for the Partnership
Agreements and the Financing Documents.

       (n)    There is no (i) injunction, writ, preliminary restraining order or
order of any nature issued by an arbitrator, court or other Governmental
Authority against Pledgor in connection with the transactions provided for
herein, or (ii) action, suit, arbitration, litigation, investigation or
proceeding of or before any arbitrator or Governmental Authority pending against
Pledgor or, to Pledgor's knowledge, threatened against Pledgor which would
reasonably be expected to materially adversely affect the right or ability of
Pledgor to fulfill its obligations under this Agreement.

       (o)    Pledgor has, independently and without reliance upon the
Administrative Agent and based on such documents and information as it has
deemed appropriate, made its own credit analysis and decision to enter into this
Agreement.

       SECTION 8. Further Assurances. (a) Pledgor agrees that from time to time,
at the expense of Pledgor, Pledgor will promptly execute and deliver all further
instruments and documents, and take all further action, that may be necessary,
or that the Administrative Agent may reasonably request, in order to perfect and
protect the pledge, assignment, hypothecation and security interest granted or
purported to be granted hereby or to enable the Administrative Agent to exercise
and enforce its rights and remedies hereunder with respect to any Collateral.
Without limiting the generality of the foregoing, Pledgor will (i) execute and
file such financing or continuation statements, or amendments thereto, and such
other instruments or notices, as may be necessary, or as the Administrative
Agent may reasonably request, in order to perfect and preserve the assignment,
hypothecation and security interest granted or purported to be granted hereby;
and (ii) mark conspicuously, at the request of the Administrative Agent, each of
its records pertaining to the Collateral with a legend, in form and substance
satisfactory to the

                                       5
<PAGE>   274

Administrative Agent, indicating that the Partnership Agreements and such
chattel paper have been assigned and are subject to the security interest
pursuant hereto.

       (b)    Pledgor hereby further authorizes the Administrative Agent to file
one or more financing or continuation statements, and amendments thereto,
relative to all or any part of the Collateral without the signature of Pledgor
where permitted by law. A photocopy or other reproduction of this Agreement or
any financing statement covering the Collateral or any part thereof shall be
sufficient as a financing statement where permitted by law.

       SECTION 9. Voting Rights; Distributions, Etc. (a) So long as no Event of
Default shall have occurred and be continuing, Pledgor shall be entitled to
receive, subject to the terms of and as contemplated by the terms of the Deposit
Account Agreement, all payments and other distributions receivable by it under
any Partnership Agreement, and shall be entitled to exercise any and all
management, voting and other partnership rights pertaining to any Collateral
including but not limited to any partnership interest or Partnership Agreements
for any purpose not inconsistent with the terms of this Agreement or any other
Financing Document; provided, however, that Pledgor shall exercise, or refrain
from exercising, any such right if such action or inaction would have a material
adverse effect on the attachment, perfection, creation or priority of the
security interest in the Collateral or any part thereof as herein granted.

       (b)    Pledgor's right to receive and retain any and all distributions in
respect of the Collateral purported to be pledged and assigned by it hereunder
shall be further limited as follows:

              (i)    distributions other than in cash in respect of, and
              instruments and other property received, receivable or otherwise
              distributed in respect of, or in exchange for, any such
              Collateral, and

              (ii)   distributions paid or payable in cash in respect of any
              such Collateral in connection with a partial or total liquidation
              or dissolution of any of the Operating Companies,

shall be, and shall be forthwith delivered to the Administrative Agent to hold
as, Collateral and shall, if received by Pledgor, be received in trust for the
benefit of the Administrative Agent, be segregated from the other property or
funds of Pledgor and be forthwith delivered to the Administrative Agent as
Collateral in the same form as so received (with any necessary endorsement or
assignment).

       (c)    Upon the occurrence and during the continuance of an Event of
Default:

              (i)    Immediately upon Pledgor's receipt of written notice from
              the Administrative Agent that the Administrative Agent intends to
              act pursuant to this clause (c)(i), all rights of Pledgor to
              exercise or refrain from exercising the voting and other
              consensual rights which it would otherwise be entitled to exercise
              shall thereupon become exercisable by the Administrative Agent,
              acting in good faith, who shall have the sole right to exercise or
              refrain from exercising such voting and other consensual rights
              unless and until such Event of Default ceases to exist.

                                       6
<PAGE>   275

              (ii)   All rights of Pledgor to receive the distributions which it
              would otherwise be authorized to receive and retain, pursuant to
              Section 9(a) and (b), above, shall become exercisable by the
              Administrative Agent who shall thereupon have the sole right to
              receive and hold as Collateral such distributions unless and until
              such Event of Default ceases to exist.

              (iii)  All distributions which are received by Pledgor contrary to
              the provisions of clause (ii), above, shall be received in trust
              for the benefit of the Administrative Agent, shall be segregated
              from other funds of Pledgor and shall be forthwith paid over to
              the Administrative Agent as Collateral in the same form as so
              received (with any necessary endorsement) for application pursuant
              to Section 17.

       SECTION 10. Place of Perfection; Records. Pledgor shall keep its place of
business and chief executive office and the office where it keeps its records
concerning the Collateral, and original copies of each Partnership Agreement and
of all other chattel paper which evidence the Collateral, at its address
specified on the signature pages hereof; or, upon 30 days' prior written notice
to the Administrative Agent, at such other location in a jurisdiction where all
action required by Section 8 shall have been taken with respect to the
Collateral. Pledgor will hold and preserve such records and will permit
representatives of the Administrative Agent at any time, upon reasonable prior
notice, during normal business hours to inspect and make abstracts from such
records.

       SECTION 11. As to the Partnership Agreements. (a) Pledgor shall at its
expense perform and observe all the terms and provisions to be performed or
observed by it under each Partnership Agreement, maintain each Partnership
Agreement in full force and effect, enforce each Partnership Agreement in
accordance with its terms, and take all such action to such end as may be from
time to time reasonably requested by the Administrative Agent.

       (b)    Pledgor shall not:

              (i)    sell, assign (by operation of law or otherwise) or
              otherwise dispose of any of the Collateral, or create or suffer to
              exist any Lien upon or with respect to any of the Collateral,
              except for the pledge, assignment, hypothecation and security
              interest created by this Agreement and Permitted Liens;

              (ii)   cancel or terminate any Partnership Agreement or consent to
              or accept any cancellation or termination thereof;

              (iii)  amend or otherwise modify in a material respect any
              Partnership Agreement; or

              (iv)   waive any material default under or material breach of any
              Partnership Agreement.

       SECTION 12. Covenants. Pledgor covenants and agrees that so long as any
Lender shall have any Commitment outstanding and until the Notes, together with
interest, and all other Secured Obligations are indefeasibly paid in full,
unless the Administrative Agent shall otherwise consent in writing, Pledgor:

       (a)    Bankruptcy. Will not file a voluntary petition or otherwise
initiate proceedings to have any Operating Company adjudicated bankrupt or
insolvent, or consent to the institution of bankruptcy or insolvency proceedings

         SECTION 13. Administrative Agent. Bank of America, N.A. has been
appointed by the Secured Parties to act as the Administrative Agent hereunder.
Pledgor hereby appoints the Administrative Agent as Pledgor's attorney-in-fact,
with full authority in the place and stead of Pledgor and in the name of Pledgor
or otherwise, from time to time in the Administrative Agent's discretion at any
time that an Event of Default shall have occurred and be continuing, to take any
action and to execute any instrument which the Administrative Agent may deem
necessary or advisable to accomplish the purposes of this Agreement, including,
without limitation, to ask, demand, collect, sue for, recover, compound, receive
and give acceptance and receipts for moneys due and to become due under or in
connection with the Collateral, to receive, indorse, and collect any drafts or
other instruments, documents and chattel paper in connection therewith, and to
file any claims or take any action or institute any proceedings which the
Administrative Agent may deem to be necessary or desirable for the collection
thereof or to enforce compliance with the terms and conditions of any
Partnership Agreement. Such appointment is coupled with an interest and is
irrevocable.

       SECTION 14. Administrative Agent May Perform. If Pledgor fails to perform
any agreement contained herein, the Administrative Agent may itself perform, or
cause performance of, such agreement, and the expenses of the Administrative
Agent incurred in connection therewith shall be payable by Pledgor under Section
20(b).

       SECTION 15. The Administrative Agent's Duties. The powers conferred on
the Administrative Agent hereunder are solely to protect its interest in the
Collateral and shall not impose any duty upon it to exercise any such powers.
Except for the safe custody of any Collateral in its possession and the
accounting for moneys actually received by it hereunder, the Administrative
Agent shall have no duty as to any Collateral or as to the taking of any
necessary steps to preserve rights against prior parties or any other rights
pertaining to any Collateral and no such duties shall be implied as arising
hereunder.

       SECTION 16. Remedies. If any Event of Default shall have occurred and be
continuing, subject to Section 9 and compliance with Requirements of Law:

       (a)    The Administrative Agent may exercise any and all rights and
remedies of Pledgor under or in connection with any Partnership Agreement, the
Partnership Interests or otherwise in respect of the Collateral, including,
without limitation, any and all rights of Pledgor to demand or otherwise require
payment of any amount under, or performance of any provision of, any Partnership
Agreement and all rights of Pledgor to control the operation of the Operating
Companies.

       (b)    All payments received by Pledgor under or in connection with any
Partnership Agreement, the Partnership Interests, or otherwise in respect of the
Collateral shall be received in trust for the benefit of the Administrative
Agent, shall be segregated from other funds of Pledgor

                                       9
<PAGE>   278

and shall be forthwith paid over to the Administrative Agent in the same form as
so received (with any necessary endorsement).

       (c)    Any Collateral repossessed by the Administrative Agent under or
pursuant to this Section 16 or any other provision hereof, and any other
Collateral whether or not so repossessed by the Administrative Agent, may be
sold, assigned, leased or otherwise disposed of under one or more contracts or
as an entirety, and without the necessity of gathering at the place of sale the
property to be sold, and in general in such manner, at such time or times, at
such place or places and on such terms as the Administrative Agent may, upon
written direction in compliance with any mandatory requirements of any
Requirement of Law, determine to be commercially reasonable. Any such
disposition which shall be a private sale or other private proceeding permitted
by such requirements shall be made upon not less than 10 days' written notice to
Pledgor specifying the time at which such disposition is to be made and the
intended sale price or other consideration therefor, and shall be subject, for
the 10 days after the giving of such notice, to the right of the Pledgor or any
nominee of Pledgor to acquire the Collateral involved at a price or for such
other consideration at least equal to the intended sale price or other
consideration so specified. To the extent permitted by Requirements of Law, the
Administrative Agent on behalf of the Lenders may bid for and become the
purchaser of the Collateral or any item thereof, offered for sale in accordance
with this Section 16. If, under mandatory requirements of any Requirement of
Law, the Administrative Agent shall be required to make disposition of the
Collateral within a period of time which does not permit the giving of notice to
Pledgor as hereinabove specified, the Administrative Agent need give Pledgor
only such notice of disposition as shall be reasonably practicable in view of
such mandatory requirements of any Requirement of Law.

       (d)    All payments made under or in connection with, or proceeds
realized from, any Partnership Agreement, the Partnership Interests, or
otherwise in respect of the Collateral and received by the Administrative Agent
shall be applied in whole or in part by the Administrative Agent against, all or
any part of the Secured Obligations in accordance with the terms of the Deposit
Account Agreement. Any surplus of such payments held by the Administrative Agent
and remaining after payment in full of all the Secured Obligations shall be paid
over to Pledgor or to whomsoever else may be lawfully entitled to receive such
surplus.

       (e)    Waiver of Claims. Except as otherwise provided in this Agreement,
PLEDGOR HEREBY WAIVES, TO THE EXTENT PERMITTED BY APPLICABLE REQUIREMENTS OF
LAW, NOTICE AND JUDICIAL HEARING IN CONNECTION WITH THE ADMINISTRATIVE AGENT
TAKING POSSESSION OR THE ADMINISTRATIVE AGENT'S DISPOSITION OF ANY OF THE
COLLATERAL, IN EACH CASE AS PERMITTED BY APPLICABLE REQUIREMENTS OF LAW,
INCLUDING, WITHOUT LIMITATION, ANY AND ALL PRIOR NOTICE AND HEARING FOR ANY
PREJUDGMENT REMEDY OR REMEDIES AND ANY SUCH RIGHT WHICH PLEDGOR WOULD OTHERWISE
HAVE UNDER THE CONSTITUTION OR ANY STATUTE OF THE UNITED STATES OR ANY POLITICAL
SUBDIVISION OF ANY SUCH JURISDICTION, and Pledgor hereby further waives:

                                       10
<PAGE>   279

              (i)    all damages occasioned by such taking of possession except
       any damages which are the direct result of the gross negligence or
       willful misconduct of either of the Administrative Agent or any Person
       acting on its behalf or instruction;

              (ii)   all other requirements as to the time, place and terms of
       sale or other requirements with respect to the enforcement of the
       Administrative Agent's rights hereunder; and

              (iii)  all rights of redemption, appraisement, valuation, stay,
       extension or moratorium now or hereafter in force under any Requirements
       of Law in order to prevent or delay the enforcement of this Agreement
       (including, without limitation, any right to claim that such enforcement
       should be stayed pending the outcome of any other action or proceeding
       (including any arbitration proceeding)) or the absolute sale of the
       Collateral or any portion thereof, and Pledgor, for itself and all who
       may claim under it, insofar as it or they now or hereafter lawfully may,
       hereby waives the benefit of all such Requirements of Law.

Any sale of, or the grant of options to purchase, or any other realization upon,
any Collateral shall, to the extent permitted by Requirements of Law, operate to
divest all right, title, interest, claim and demand, either at law or in equity,
of Pledgor therein and thereto, and shall be a perpetual bar both at law and in
equity against Pledgor and against any and all Persons claiming or attempting to
claim the Collateral so sold, optioned or realized upon, or any part thereof,
from, through and under Pledgor.

       SECTION 17. Application of Proceeds. Notwithstanding any other provision
of this Agreement, all moneys collected by the Administrative Agent upon any
sale or other disposition of the Collateral pursuant to Section 16, together
with all other moneys received by the Administrative Agent hereunder, shall be
applied in accordance with the Deposit Account Agreement.

       SECTION 18. Remedies Cumulative. No failure or delay on the part of the
Administrative Agent or any Secured Party in exercising any right, power or
privilege hereunder or under any other Financing Document and no course of
dealing between Pledgor and the Administrative Agent or any Secured Party shall
operate as a waiver thereof; nor shall any single or partial exercise of any
right, power or privilege hereunder or under any other Financing Document
preclude any other or further exercise thereof or the exercise of any other
right, power or privilege hereunder or thereunder. The rights, powers and
remedies herein or in any other Financing Document expressly provided are
cumulative and not exclusive of any rights, powers or remedies which the
Administrative Agent or any Secured Party would otherwise have. No notice to or
demand on Pledgor in any case shall entitle Pledgor to any other or further
notice or demand in similar or other circumstances or constitute a waiver of the
rights of the Administrative Agent or any Secured Party to any other or further
action in any circumstances without notice or demand.

       SECTION 19. Discontinuance of Proceedings. In case the Administrative
Agent shall have instituted any proceeding to enforce any right, power or remedy
under this Agreement by

                                       11
<PAGE>   280

foreclosure, sale or otherwise, and such proceeding shall have been discontinued
or abandoned for any reason or shall have been determined adversely to the
Administrative Agent, then and in every such case Pledgor, the Administrative
Agent and each holder of any of the Secured Obligations shall be restored to
their former positions and rights hereunder with respect to the Collateral
subject to the security interest created under this Agreement, and all rights,
remedies and powers of the Administrative Agent shall continue as if no such
proceeding had been instituted.

       SECTION 20. Indemnity and Expenses. (a) Pledgor agrees to indemnify and
hold harmless the Administrative Agent and each Secured Party from and against
any and all claims, losses and liabilities arising out of or resulting from the
Collateral or Pledgor's pledge and assignment under this Agreement (including,
without limitation, enforcement against Pledgor of this Agreement), except
claims, losses or liabilities resulting from the Administrative Agent's or any
Secured Party's gross negligence or willful misconduct.

       (b)    Pledgor will upon demand pay to the Administrative Agent or any
Secured Party the amount of any and all reasonable expenses, including the
reasonable fees and expenses of its counsel and of any experts and agents, which
the Administrative Agent or any Secured Party may incur in connection with (i)
the administration of this Agreement, (ii) the sale of, collection from, or
other realization upon, any of the Collateral of Pledgor, (iii) the exercise or
enforcement (whether through negotiations, legal proceedings or otherwise) of
any of the rights of the Administrative Agent or any Secured Party hereunder
against Pledgor or (iv) the failure by Pledgor to perform or observe any of the
provisions hereof.

       SECTION 21. Security Interest Absolute. The obligations of Pledgor under
this Agreement are independent of the Secured Obligations, and a separate action
or actions may be brought and prosecuted against Pledgor to enforce this
Agreement, irrespective of whether any other action is brought against the
Pledgor, any other pledgor or any guarantor of the Secured Obligations or
whether the Pledgor, any other pledgor or any guarantor of the Secured
Obligations is joined in any such action or actions. All rights of the
Administrative Agent and the assignment, hypothecation and security interest
hereunder, and all obligations of Pledgor hereunder, shall be absolute and
unconditional, to the extent permitted by applicable law, irrespective of:

       (a)    any lack of validity or enforceability of this Agreement, the
Credit Agreement, any other Financing Document or any other agreement or
instrument relating to any thereof, the absence of any action to enforce the
same, any release of any Borrower Entity or Pledgor, the recovery of any
judgment against any Borrower Entity or Pledgor, any action to enforce the same
or any other circumstance which might otherwise constitute a legal or equitable
discharge or defense of Pledgor;

       (b)    any occurrence or condition whatsoever, including without
limitation, (i) any compromise, settlement, release, waiver, renewal, extension,
indulgence or modification of, or any change in, any of the obligations of any
Borrower Entity or Pledgor contained in this Agreement, the Credit Agreement or
any other Financing Document, (ii) any impairment,

                                       12
<PAGE>   281

modification, release or limitation of the liability of any Borrower Entity or
Pledgor or any of their estates in bankruptcy, or any remedy for the enforcement
thereof, resulting from the operation of any present or future provision of any
applicable bankruptcy law, as amended, or other statute or from the decision of
any court, (iii) the assertion or exercise by Pledgor, the Administrative Agent
or any other Secured Party of any rights or remedies, (iv) the assignment or the
purported assignment of any property as security for the Secured Obligations,
including all or any part of the rights of Pledgor under this Agreement, (v) the
extension of the time for payment by any Borrower Entity or any other guarantor
of any payments or other sums or any part thereof owing or payable under any of
the terms and provisions of any Financing Document or of the time for
performance by any Borrower Entity or Pledgor of any other obligations under or
arising out of any terms or provisions or the extension of the renewal of any
thereof, (vi) the modification or amendment (whether material or otherwise) of
any duty, agreement or obligation of any Borrower Entity or Pledgor set forth in
any Financing Document, (vii) the voluntary or involuntary liquidation,
dissolution, sale or other disposition of all or substantially all of the
assets, marshalling of assets and liabilities, receivership, insolvency,
bankruptcy, assignment for the benefit of creditors, reorganization,
arrangement, composition or readjustment of, or other similar proceeding
affecting any Borrower Entity or Pledgor or any of their respective assets, or
the disaffirmancy of this Agreement or any Financing Document in any such
proceeding, (viii) the release or discharge of any Borrower Entity or Pledgor
from the performance or observance of any agreement, covenant, term or condition
contained in any of such instruments by operation of law, (ix) the
unenforceability of this Agreement or any Financing Document or (x) any other
circumstance which might otherwise constitute a legal or equitable discharge of
a surety or guarantor; or

       (c)    any exchange, release or non-perfection of any collateral, or any
release or amendment or waiver of or consent to departure from any other
guarantee, for all or any of the Secured Obligations.

       SECTION 22. Amendment; Waiver. No amendment or waiver of any provision of
this Agreement shall be effective unless the same shall be undertaken and
accomplished in accordance with the requirements of Section 9.02 of the Credit
Agreement. No delay on the part of any Secured Party in the exercise of any
right, power or remedy shall operate as a waiver thereof, nor shall any single
or partial waiver by such Secured Party of any right, power or remedy preclude
any further exercise thereof, or the exercise of any other right, power or
remedy.

       SECTION 23. Addresses for Notices. All notices, requests and other
communications to Pledgor or the Administrative Agent shall be in writing
(including bank wire, cable, telex, telecopy or similar teletransmission or
writing) and shall be given, in the case of Pledgor to its address, or telex,
cable or telecopy number set forth on the signature page hereof, and in the case
of the Administrative Agent, to it at its address, or telex, cable or telecopy
number set forth in Annex II to the Credit Agreement or such other address or
telex, cable or telecopy number as each party may hereafter specify by notice to
such other party. Each such notice, request or other communication shall be
effective (i) if given by telex, when such telex is transmitted to the telex
number specified on the signature page hereof or in Annex II, as the case may
be, and the appropriate answerback is received, (ii) if given by telecopy, when
such telecopy is transmitted to the telecopy number specified on the signature
page hereof or in Annex II, as the case may be,

                                       13
<PAGE>   282

and receipt thereof is confirmed in writing, or (iii) if given by any other
means (including, without limitation, by air courier), when delivered at the
address specified on the signature page hereof or in Annex II, as the case may
be.

       SECTION 24. Continuing Assignment, Pledge and Security Interest, Transfer
of Note. This Agreement shall create a continuing pledge, assignment of,
hypothecation of and security interest in the Collateral and shall (i) remain in
full force and effect until no Lender shall have any Commitment outstanding, and
until the Notes, together with interest, and all other Secured Obligations are
indefeasibly paid in full, (ii) be binding upon Pledgor, its successors and
assigns, provided, that Pledgor may not transfer or assign any or all of its
rights or obligations hereunder without the prior written consent of each
Lender, and (iii) inure to the benefit of, and be enforceable by, the
Administrative Agent, the Secured Parties and their respective successors,
transferees and assigns. Without limiting the generality of the foregoing clause
(iii), any Secured Party may assign or otherwise transfer all or any portion of
its rights in the Secured Obligations to the extent and in the manner provided
in the Credit Agreement, and such assignee shall thereupon become vested with
all the benefits in respect thereof granted to such Secured Party herein or
otherwise. Upon the indefeasible payment in full of the Secured Obligations and
the expiration or termination of the Commitments, the security interest granted
hereby shall terminate and all rights to the Collateral shall revert to Pledgor.
Upon any such termination, the Administrative Agent will, at Pledgor's expense,
execute and deliver to Pledgor such documents including UCC termination
statements as Pledgor shall reasonably request to evidence such termination.

       SECTION 25. Severability. Any provision hereof that is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof and without affecting the validity or enforceability
of any provision in any other jurisdiction.

       SECTION 26. GOVERNING LAW; TERMS. THIS AGREEMENT SHALL BE GOVERNED BY AND
INTERPRETED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK OTHER THAN ANY
SUCH REQUIREMENT OF LAWS THAT WOULD APPLY THE LAWS OF ANOTHER JURISDICTION,
EXCEPT TO THE EXTENT THAT THE LAWS OF ANOTHER JURISDICTION ARE MANDATORILY
APPLICABLE AND EXCEPT TO THE EXTENT THAT THE VALIDITY OR PERFECTION OF THE
SECURITY INTEREST HEREUNDER, OR REMEDIES HEREUNDER, IN RESPECT OF ANY PARTICULAR
COLLATERAL ARE GOVERNED BY THE LAWS OF A JURISDICTION OTHER THAN THE STATE OF
NEW YORK. UNLESS OTHERWISE DEFINED HEREIN OR IN THE CREDIT AGREEMENT, TERMS USED
IN ARTICLE 9 OF THE NY UCC ARE USED HEREIN AS THEREIN DEFINED. ANY DISPUTE
ARISING OUT OF, CONNECTED WITH, RELATED TO, OR INCIDENTAL TO THE RELATIONSHIP
ESTABLISHED BETWEEN THE PLEDGOR AND EACH SECURED PARTY IN CONNECTION WITH THIS
AGREEMENT AND THE OTHER FINANCING DOCUMENTS, AND WHETHER ARISING IN CONTRACT,
TORT, EQUITY OR OTHERWISE, SHALL BE RESOLVED IN ACCORDANCE WITH THE INTERNAL
LAWS (AS OPPOSED TO THE CONFLICTS OF LAWS PROVISIONS) AND DECISIONS OF THE STATE
OF NEW YORK.

                                       14
<PAGE>   283

       SECTION 27. CONSENT TO JURISDICTION; WAIVER OF JURY TRIAL. (a) PLEDGOR
AND EACH SECURED PARTY AGREE THAT ALL DISPUTES BETWEEN THEM ARISING OUT OF,
CONNECTED WITH, RELATED TO, OR INCIDENTAL TO THE RELATIONSHIP ESTABLISHED
BETWEEN THEM IN CONNECTION WITH THIS AGREEMENT AND THE OTHER FINANCING
DOCUMENTS, AND WHETHER ARISING IN CONTRACT, TORT, EQUITY, OR OTHERWISE, SHALL BE
RESOLVED ONLY BY STATE OR FEDERAL COURTS LOCATED IN NEW YORK, NEW YORK, BUT
PLEDGOR AND EACH SECURED PARTY ACKNOWLEDGE THAT ANY APPEALS FROM THOSE COURTS
MAY HAVE TO BE HEARD BY A COURT LOCATED OUTSIDE OF NEW YORK, NEW YORK. PLEDGOR
WAIVES IN ALL DISPUTES ANY OBJECTION THAT IT MAY HAVE TO THE LOCATION OF THE
COURT CONSIDERING THE DISPUTE INCLUDING, WITHOUT LIMITATION, ANY OBJECTION TO
THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS.

       (b)    PLEDGOR AND THE SECURED PARTIES EACH WAIVE ANY RIGHT TO HAVE A
JURY PARTICIPATE IN RESOLVING ANY DISPUTE, WHETHER SOUNDING IN CONTRACT, TORT,
OR OTHERWISE ARISING OUT OF, CONNECTED WITH, RELATED TO OR INCIDENTAL TO THE
RELATIONSHIP ESTABLISHED BETWEEN THEM IN CONNECTION WITH THIS AGREEMENT AND THE
OTHER FINANCING DOCUMENTS. INSTEAD, ANY DISPUTES RESOLVED IN COURT WILL BE
RESOLVED IN A BENCH TRIAL WITHOUT A JURY.

       SECTION 28. Execution in Counterparts. This Agreement may be executed in
any number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed shall be deemed to be an original
and all of which taken together shall constitute one and the same instrument.

       SECTION 29. Limitation on Recourse. The obligations of Pledgor hereunder
are obligations solely of Pledgor and shall not constitute a debt or obligation
of any direct or indirect partner or shareholder of Pledgor or any of their
respective directors, officers, agents or employees (each such Person, a
"Non-Recourse Party"). No Non-Recourse Party shall be liable for any amount
payable by Pledgor under this Agreement and the Secured Parties shall not seek a
money judgment or deficiency or personal judgment against any Non-Recourse Party
for payment of the indebtedness payable by Pledgor evidenced by this Agreement.
No property or assets of any Non-Recourse Party, other than as contemplated in
the Financing Documents, shall be sold, levied upon or otherwise used to satisfy
any judgment rendered in connection with any action brought against Pledgor with
respect to this Agreement or the other Financing Documents. The foregoing
acknowledgments, agreements and waivers shall be enforceable by any Non-Recourse
Party. Notwithstanding the foregoing, nothing in this Section shall limit or
affect or be construed to limit or affect the obligations and liabilities of any
Credit Party or any other Non-Recourse Party (a) in accordance with the terms of
any Transaction Document or Financing Document creating such liabilities and
obligations to which such Credit Party or Non-Recourse Party is a party, (b)
arising from liability pursuant to applicable Requirements of Law for such
Credit Party's or such Non-Recourse Party's fraudulent actions, knowing
misrepresentations or willful misconduct or (c) with respect to amounts
distributed to it in violation of Section 6.10 of the Credit Agreement.

of America Securities LLC and Paribas, as lead arrangers (the "Lead Arrangers"),
Bank of America, N.A., as Issuing Bank and the Lenders named on the signature

         WHEREAS, the Credit Agreement contemplates the execution, delivery and

accordance with the terms hereof; and

         WHEREAS, the Borrower Entities, the Administrative Agent and the
Lenders have entered into a Deposit Account Agreement, dated as of July 28, 1999
(as the same may be amended, supplemented or otherwise modified from time to
time, the "Deposit Account Agreement"), providing for, among other things, the
establishment of the Accounts and the application of the proceeds of the
Collateral;

         NOW, THEREFORE, in consideration of the foregoing and in order to
induce the Lenders to enter into the Credit Agreement, to make available to the
Borrower such credit facilities and for other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, Pledgor hereby
agrees as follows:

         SECTION 1. Pledge; Assignment; Grant of Security Interest. Pledgor
hereby pledges, hypothecates and assigns to the Administrative Agent, and hereby
grants to the Administrative

                                       1

Agent for the benefit of the Secured Parties, a pledge and assignment of, and a
security interest in, all of its right, title and interest in and to the
following (the "Collateral"):

         (a)      All general and limited partnership interests now owned or
hereafter acquired by Pledgor in and to the Borrower (collectively, the
"Partnership Interests") and the partnership agreement relating to the Borrower
(the "Partnership Agreement") and all rights related thereto, including, without
limitation, (i) all rights of Pledgor as a general or limited partner, as the
case may be, and all rights to receive distributions, cash, instruments and
other property from time to time receivable or otherwise distributable in
respect of any Partnership Interest or pursuant to the Partnership Agreement,
(ii) all rights of Pledgor to receive proceeds of any insurance, indemnity,
warranty or guaranty with respect to any Partnership Interest or the Partnership
Agreement, (iii) all claims of Pledgor for damages arising out of or for breach
of or default under the Partnership Agreement, (iv) the right of Pledgor to
terminate the Partnership Agreement, to perform and exercise consensual or
voting rights thereunder and to compel performance and otherwise exercise all
remedies thereunder, (v) all rights of Pledgor as a general or limited partner
of the Borrower, to any property and assets of the Borrower (whether real
property, inventory, equipment, contract rights, accounts, receivables, general
intangibles, securities, instruments, chattel paper, documents, chooses in
action or otherwise), and (vi) all certificates or instruments evidencing an
ownership or partnership interest in the Borrower or its assets; and

         (b)      to the extent not included in the foregoing, all proceeds of
any and all of the foregoing (including, without limitation, proceeds that
constitute property of the types described above).

         SECTION 2. Security for Secured Obligations. This Agreement secures the
prompt and complete payment and performance of (a) all Obligations of the
Borrower now or hereafter existing under the Financing Documents, (b) all
obligations of each Subsidiary of the Borrower under the Subsidiary Guarantee
and (c) the due performance and compliance of all other obligations of any
Borrower Entity under any of the Financing Documents (collectively, the "Secured
Obligations"). Without limiting the generality of the foregoing, this Agreement
secures the payment of all amounts which constitute part of the Secured
Obligations and would be owed by the Borrower to the Secured Parties but for the
fact that they are unenforceable or not allowable due to the existence of a
bankruptcy, reorganization or similar proceeding involving any Credit Party.

         SECTION 3. Pledgor Remains Liable. Anything herein to the contrary
notwithstanding, (a) Pledgor shall remain liable under the Partnership Agreement
and the other contracts and agreements included in the Collateral to the extent
set forth therein to perform all of its duties and obligations thereunder to the
same extent as if this Agreement had not been executed, (b) the exercise by any
Secured Party of any of the rights hereunder shall not release Pledgor from any
of its duties or obligations under the contracts and agreements included in the
Collateral and (c) neither the Administrative Agent nor any Secured Party shall
have any obligation or liability under the contracts and agreements included in
the Collateral or otherwise by reason of this Agreement, nor shall the
Administrative Agent or any Secured Party be obligated to perform any of the
obligations or duties of Pledgor thereunder or to take any action to collect or
enforce any claim assigned hereunder.

<PAGE>   292

         SECTION 4. Delivery of Collateral. All certificates or instruments
representing or evidencing the Collateral at any time shall be delivered to and
held by or on behalf of the Administrative Agent pursuant hereto and shall be in
suitable form for transfer by delivery, or shall be accompanied by duly executed
instruments of transfer or assignment in blank, all in form and substance
satisfactory to the Administrative Agent. The Administrative Agent shall have
the right, upon the occurrence and continuance of an Event of Default, in its
discretion and without notice to Pledgor, to transfer to or to register in the
name of the Administrative Agent or any of its nominees any or all of the
Collateral, subject only to compliance with Requirements of Law, the terms and
conditions of the Credit Agreement and the revocable rights specified in Section
9(a). In addition, the Administrative Agent shall have the right at any time to
exchange certificates or instruments representing or evidencing Collateral for
certificates or instruments of smaller or larger denominations.

         SECTION 5. No Subrogation. Pledgor shall not exercise any rights which
it may acquire by way of subrogation under this Agreement, by any payments made
hereunder or otherwise, until all Secured Obligations shall have been
indefeasibly paid in full and all Commitments have been terminated. If any
amount shall be paid to Pledgor on account of such subrogation rights at any
time when all Secured Obligations shall not have been indefeasibly paid in full
(whether pursuant to a claim in any bankruptcy or similar proceeding or
otherwise) or when any Commitment shall remain outstanding, such amount shall be
held in trust for the benefit of the Administrative Agent and the Secured
Parties and shall forthwith be paid to the Administrative Agent to be credited
and applied to the Secured Obligations, whether matured or unmatured, in
accordance with Section 17.

         SECTION 6. Reinstatement. This Agreement shall continue to be
effective, or be reinstated, as the case may be, if at any time payment, or any
part thereof, of any of the Secured Obligations is rescinded or must otherwise
be restored or returned by any Secured Party upon the insolvency, bankruptcy,
dissolution, liquidation or reorganization of Pledgor, or upon or as a result of
the appointment of a receiver, intervenor or conservator of, or trustee or
similar officer for, Pledgor or any substantial part of its property, or
otherwise, all as though such payments had not been made.

         SECTION 7. Representations and Warranties.  Pledgor represents and
warrants as follows:

         (a)      Pledgor (i) is duly formed, validly existing and in good
standing under the laws of the State of Delaware, (ii) has all requisite power
and authority to own its property and assets, to borrow money and to transact
the business in which it is presently engaged and in which it proposes to be
engaged, (iii) has duly qualified and is authorized to do business and is in
good standing in every jurisdiction where the character of its properties or the
nature of its activities makes such qualification necessary and (iv) is in full
compliance with its Governing Documents, all material Contractual Obligations,
all applicable material Requirements of Law and all material Governmental
Approvals. As of the date hereof, Pledgor is the sole Limited Partner of the
Borrower.

         (b)      The execution, delivery and performance by Pledgor of this
Agreement and the consummation of the transactions contemplated hereby (i) are
within its powers, (ii) have been duly authorized by all necessary corporate
action, (iii) do not and will not contravene (A) its Governing Documents or (B)
any material Requirement of Law, any material Contractual Obligation or any
material Governmental Approval binding on or affecting it and (iv) does not and
will not conflict with or be inconsistent with or result in any breach of any of
the material terms, covenants, conditions or provisions of, or constitute a
default under, or result in the creation or imposition of (or the obligation to
create or impose) any Lien (except Permitted Liens) upon any of its properties
or assets pursuant to, the terms of any material Contractual Obligation binding
on or affecting it.

         (c)      Pledgor has duly executed and delivered this Agreement and
this Agreement constitutes the legal, valid and binding obligation of Pledgor,
enforceable against Pledgor in accordance with its terms, except as enforcement
thereof may be subject to (i) the effect of any applicable bankruptcy,
insolvency, reorganization, moratorium or similar laws affecting creditors'
rights generally and (ii) general principles of equity.

         (d)      No Governmental Approval or approval of any other Person
(except such as have been duly obtained, made or given, and are in full force
and effect) is required to authorize, or is required in connection with (i) the
execution, delivery or performance of this Agreement by Pledgor or the
consummation of any of the transactions contemplated hereby, (ii) the legality,
validity, binding effect or enforceability of this Agreement or the perfection
and maintenance of the security interest created hereby (including the first
priority nature of such security interest) or (iii) for the exercise by the
Administrative Agent of the voting or other rights provided for in this
Agreement or the remedies in respect of the Collateral pursuant to this
Agreement. All applicable waiting periods relating to any such Governmental
Approval or other approval which are required and have been obtained have
expired without any adverse action taken with respect thereto.

         (e)      The Partnership Agreement, a true and complete copy of which
has been furnished to the Administrative Agent, has been duly authorized,
executed and delivered by Pledgor and is in full force and effect and is binding
upon and enforceable against Pledgor in accordance with its terms. There exists
no default under the Partnership Agreement.

         (f)      This Agreement creates a valid security interest in the
Collateral purported to be pledged and assigned by Pledgor hereunder securing
the payment of the Secured Obligations.

         (g)      Upon the filing of the financing statements (the "Financing
Statements") referenced in Schedule I hereof under the Uniform Commercial Code
as in effect in the State of Delaware (the "Delaware UCC"), the security
interest is created hereby shall be perfected under the Delaware UCC, to the
extent that the Collateral constitutes "general intangibles" (as defined in the
Delaware UCC) and no further filings or other actions are necessary to perfect
such security interest. Upon filing of such Financing Statements pursuant to the
Delaware UCC, such security interests, as so perfected, are first priority
security interests.

         (h)      When any certificates or instruments evidencing the Collateral
shall be delivered hereunder, and for so long as such certificates or
instruments shall remain in the possession of

                                       4
<PAGE>   294

the Administrative Agent in the State of New York or the State of North
Carolina, the security interest in such Collateral created hereby shall be
perfected under the Uniform Commercial Code as in effect in the State of New
York (the "NY UCC") or the State of North Carolina, as applicable, and such
security interest, as so perfected, will be a first priority security interest.

         (i)      The security interest created by this Agreement in the
Collateral described in clause (a) of Section 1 hereof has been registered in
the name of the Administrative Agent in the register maintained for such purpose
at the chief executive office and principal place of business of the Borrower,
and, to the extent that such Collateral constitutes "uncertificated securities"
(as defined in the Delaware UCC), such security interest is perfected under the
Delaware UCC and, as so perfected, is a first priority security interest.

         (j)      The chief place of business and chief executive office of
Pledgor and the office where Pledgor keeps its records concerning the Collateral
is set forth under its name on the signature page hereof.

         (k)      Pledgor is the legal and beneficial owner of the Collateral
purported to be pledged and assigned by it hereunder, free and clear of any
Lien, other than Permitted Liens. No effective financing statement or other
instrument similar in effect covering all or any part of such Collateral has
been executed or authorized by Pledgor or, is on file in any recording office,
except such as may have been filed in favor of the Administrative Agent relating
to this Agreement. Pledgor has no trade name.

         (l)      There are no conditions precedent to the effectiveness of this
Agreement that have not been satisfied or waived.

         (m)      No part of the Collateral is subject to the terms of any
agreement restricting the sale or transfer of such Collateral, except for the
Partnership Agreement and the Financing Documents.

         (n)      There is no (i) injunction, writ, preliminary restraining
order or order of any nature issued by an arbitrator, court or other
Governmental Authority against Pledgor in connection with the transactions
provided for herein, or (ii) action, suit, arbitration, litigation,
investigation or proceeding of or before any arbitrator or Governmental
Authority pending against Pledgor or, to Pledgor's knowledge, threatened against
Pledgor which would reasonably be expected to materially adversely affect the
right or ability of Pledgor to fulfill its obligations under this Agreement.

         (o)      Pledgor has, independently and without reliance upon the
Administrative Agent and based on such documents and information as it has
deemed appropriate, made its own credit analysis and decision to enter into this
Agreement.

         SECTION 8. Further Assurances. (a) Pledgor agrees that from time to
time, at the expense of Pledgor, Pledgor will promptly execute and deliver all
further instruments and documents, and take all further action, that may be
necessary, or that the Administrative Agent may reasonably request, in order to
perfect and protect the pledge, assignment, hypothecation and security interest
granted or purported to be granted hereby or to enable the Administrative Agent
to exercise and enforce its rights and remedies hereunder with respect to any
Collateral.

                                       5
<PAGE>   295

Without limiting the generality of the foregoing, Pledgor will (i) execute and
file such financing or continuation statements, or amendments thereto, and such
other instruments or notices, as may be necessary, or as the Administrative
Agent may reasonably request, in order to perfect and preserve the assignment,
hypothecation and security interest granted or purported to be granted hereby;
and (ii) mark conspicuously, at the request of the Administrative Agent, each of
its records pertaining to the Collateral with a legend, in form and substance
satisfactory to the Administrative Agent, indicating that the Partnership
Agreement and such chattel paper have been assigned and are subject to the
security interest pursuant hereto.

         (b)      Pledgor hereby further authorizes the Administrative Agent to
file one or more financing or continuation statements, and amendments thereto,
relative to all or any part of the Collateral without the signature of Pledgor
where permitted by law. A photocopy or other reproduction of this Agreement or
any financing statement covering the Collateral or any part thereof shall be
sufficient as a financing statement where permitted by law.

         SECTION 9. Voting Rights; Distributions, Etc. (a) So long as no Event
of Default shall have occurred and be continuing, but subject, nevertheless, at
all times to the restrictions imposed by Section 6.10 of the Credit Agreement
and by subsection (b) below, Pledgor shall be entitled to receive free and clear
of the interest of the Administrative Agent granted under this Agreement all
payments and other distributions receivable by it under the Partnership
Agreement that are Distributions expressly permitted by the Deposit Account
Agreement and the Credit Agreement, and shall be entitled to exercise any and
all management, voting and other partnership rights pertaining to any Collateral
including but not limited to any partnership interest or the Partnership
Agreement in the Borrower for any purpose not inconsistent with the terms of
this Agreement or any other Financing Document; provided, however, that Pledgor
shall exercise, or refrain from exercising, any such right if such action or
inaction would have a material adverse effect on the attachment, perfection,
creation or priority of the security interest in the Collateral or any part
thereof as herein granted.

         (b)      Pledgor's right to receive and retain any and all
distributions in respect of the Collateral purported to be pledged and assigned
by it hereunder shall be further limited as follows:

                  (i)      distributions other than in cash in respect of, and
                  instruments and other property received, receivable or
                  otherwise distributed in respect of, or in exchange for, any
                  such Collateral, and

                  (ii)     distributions paid or payable in cash in respect of
                  any such Collateral in connection with a partial or total
                  liquidation or dissolution of the Borrower,

shall be, and shall be forthwith delivered to the Administrative Agent to hold
as, Collateral and shall, if received by Pledgor, be received in trust for the
benefit of the Administrative Agent, be segregated from the other property or
funds of Pledgor and be forthwith delivered to the Administrative Agent as
Collateral in the same form as so received (with any necessary endorsement or
assignment).

         (c)      Upon the occurrence and during the continuance of an Event of
Default:

                  (i)      Immediately upon Pledgor's receipt of written notice
                  from the Administrative Agent that the Administrative Agent
                  intends to act pursuant to this clause (c)(i), all rights of
                  Pledgor to exercise or refrain from exercising the voting and
                  other consensual rights which it would otherwise be entitled
                  to exercise shall thereupon become exercisable by the
                  Administrative Agent, acting in good faith, who shall have the
                  sole right to exercise or refrain from exercising such voting
                  and other consensual rights unless and until such Event of
                  Default ceases to exist.

                  (ii)     All rights of Pledgor to receive the distributions
                  which it would otherwise be authorized to receive and retain,
                  pursuant to Section 9(a) and (b), above, shall become
                  exercisable by the Administrative Agent who shall thereupon
                  have the sole right to receive and hold as Collateral such
                  distributions unless and until such Event of Default ceases to
                  exist.

                  (iii)    All distributions which are received by Pledgor
                  contrary to the provisions of clause (ii), above, shall be
                  received in trust for the benefit of the Administrative Agent,
                  shall be segregated from other funds of Pledgor and shall be
                  forthwith paid over to the Administrative Agent as Collateral
                  in the same form as so received (with any necessary
                  endorsement) for application pursuant to Section 17.

         SECTION 10. Place of Perfection; Records. Pledgor shall keep its place
of business and chief executive office and the office where it keeps its records
concerning the Collateral, and original copies of the Partnership Agreement and
of all other chattel paper which evidence the Collateral, at its address
specified on the signature pages hereof; or, upon 30 days' prior written notice
to the Administrative Agent, at such other location in a jurisdiction where all
action required by Section 8 shall have been taken with respect to the
Collateral. Pledgor will hold and preserve such records and will permit
representatives of the Administrative Agent at any time, upon reasonable prior
notice, during normal business hours to inspect and make abstracts from such
records.

         SECTION 11. As to the Partnership Agreement. (a) Pledgor shall at its
expense perform and observe all the terms and provisions to be performed or
observed by it under the Partnership Agreement, maintain the Partnership
Agreement in full force and effect, enforce the Partnership Agreement in
accordance with its terms, and take all such action to such end as may be from
time to time reasonably requested by the Administrative Agent.

         (b)      Pledgor shall not:

                  (i)      sell, assign (by operation of law or otherwise) or
                  otherwise dispose of any of the Collateral, or create or
                  suffer to exist any Lien upon or with respect to any of the
                  Collateral, except for the pledge, assignment, hypothecation
                  and security interest created by this Agreement and Permitted
                  Liens;

<PAGE>   297

                  (ii)     cancel or terminate the Partnership Agreement or
                  consent to or accept any cancellation or termination thereof;

                  of the Partnership Agreement.

         SECTION 12. Covenants. Pledgor covenants and agrees that so long as any
Lender shall have any Commitment outstanding and until the Notes, together with
interest, and all other Secured Obligations are indefeasibly paid in full,
unless the Administrative Agent shall otherwise consent in writing, Pledgor:

         (a)      Maintenance of Register. Will cause the Borrower to maintain
at all times a register at its chief place of business and chief executive

Agreement) or upon any part thereof. The Pledgor shall have the right, however,
to contest in good faith the validity or amount of any such tax, assessment,
charge or levy by proper proceedings, and may permit the taxes, assessments,
charges or levies so contested to remain unpaid during the period of such
contest if: (a) the Pledgor diligently prosecutes such contest in good faith and
by appropriate proceedings and has established Acceptable Reserves; (b) during
the period of such contest, the enforcement of any contested item is effectively

         SECTION 13. Administrative Agent. Bank of America, N.A. has been
appointed by the Secured Parties to act as the Administrative Agent hereunder.
Pledgor hereby appoints the Administrative Agent as Pledgor's attorney in fact,

without limitation, to ask, demand, collect, sue for, recover, compound, receive
and give acceptance and receipts for moneys due and to become due under or in
connection with the Collateral, to receive, indorse, and collect any drafts or
other instruments, documents and chattel paper in connection therewith, and to
file any claims or take any action or institute any proceedings which the
Administrative Agent may deem to be necessary or desirable for the collection
thereof or to enforce compliance with the terms and conditions of the
Partnership Agreement. Such appointment is coupled with an interest and is
irrevocable.

         SECTION 14. Administrative Agent May Perform. If Pledgor fails to
perform any agreement contained herein, the Administrative Agent may itself
perform, or cause performance of, such agreement, and the expenses of the
Administrative Agent incurred in connection therewith shall be payable by
Pledgor under Section 20(b).

         SECTION 15. The Administrative Agent's Duties. The powers conferred on
the Administrative Agent hereunder are solely to protect its interest in the
Collateral and shall not impose any duty upon it to exercise any such powers.
Except for the safe custody of any Collateral in its possession and the
accounting for moneys actually received by it hereunder, the Administrative
Agent shall have no duty as to any Collateral or as to the taking of any
necessary steps to preserve rights against prior parties or any other rights
pertaining to any Collateral and no such duties shall be implied as arising
hereunder.

         SECTION 16. Remedies. If any Event of Default shall have occurred and
be continuing, subject to Section 9 and compliance with Requirements of Law:

         (a)      The Administrative Agent may exercise any and all rights and
remedies of Pledgor under or in connection with the Partnership Agreement, the
Partnership Interests or otherwise in respect of the Collateral, including,
without limitation, any and all rights of Pledgor to demand or otherwise require
payment of any amount under, or performance of any provision of, the Partnership
Agreement and all rights of Pledgor to control the operation of the Borrower.

         (b)      All payments received by Pledgor under or in connection with
the Partnership Agreement, the Partnership Interests, or otherwise in respect of
the Collateral shall be received in trust for the benefit of the Administrative
Agent, shall be segregated from other funds of Pledgor

                                       10
<PAGE>   300

and shall be forthwith paid over to the Administrative Agent in the same form as
so received (with any necessary endorsement).

         (c)      Any Collateral repossessed by the Administrative Agent under
or pursuant to this Section 16 or any other provision hereof, and any other
Collateral whether or not so repossessed by the Administrative Agent, may be
sold, assigned, leased or otherwise disposed of under one or more contracts or
as an entirety, and without the necessity of gathering at the place of sale the
property to be sold, and in general in such manner, at such time or times, at
such place or places and on such terms as the Administrative Agent may, upon
written direction in compliance with any mandatory requirements of any
Requirement of Law, determine to be commercially reasonable. Any such
disposition which shall be a private sale or other private proceeding permitted
by such requirements shall be made upon not less than 10 days' written notice to
Pledgor specifying the time at which such disposition is to be made and the
intended sale price or other consideration therefor, and shall be subject, for
the 10 days after the giving of such notice, to the right of the Pledgor or any
nominee of Pledgor to acquire the Collateral involved at a price or for such
other consideration at least equal to the intended sale price or other
consideration so specified. To the extent permitted by Requirements of Law, the
Administrative Agent on behalf of the Lenders may bid for and become the
purchaser of the Collateral or any item thereof, offered for sale in accordance
with this Section 16. If, under mandatory requirements of any Requirement of
Law, the Administrative Agent shall be required to make disposition of the
Collateral within a period of time which does not permit the giving of notice to
Pledgor as hereinabove specified, the Administrative Agent need give Pledgor
only such notice of disposition as shall be reasonably practicable in view of
such mandatory requirements of any Requirement of Law.

         (d)      All payments made under or in connection with, or proceeds
realized from, the Partnership Agreement, the Partnership Interests, or
otherwise in respect of the Collateral and received by the Administrative Agent
shall be applied in whole or in part by the Administrative Agent against, all or
any part of the Secured Obligations in accordance with the terms of the Deposit
Account Agreement. Any surplus of such payments held by the Administrative Agent
and remaining after payment in full of all the Secured Obligations shall be paid
over to Pledgor or to whomsoever else may be lawfully entitled to receive such
surplus.

         (e)      Waiver of Claims. Except as otherwise provided in this
Agreement, PLEDGOR HEREBY WAIVES, TO THE EXTENT PERMITTED BY APPLICABLE
REQUIREMENTS OF LAW, NOTICE AND JUDICIAL HEARING IN CONNECTION WITH THE
ADMINISTRATIVE AGENT TAKING POSSESSION OR THE ADMINISTRATIVE AGENT'S DISPOSITION
OF ANY OF THE COLLATERAL, IN EACH CASE AS PERMITTED BY APPLICABLE REQUIREMENTS
OF LAW, INCLUDING, WITHOUT LIMITATION, ANY AND ALL PRIOR NOTICE AND HEARING FOR
ANY PREJUDGMENT REMEDY OR REMEDIES AND ANY SUCH RIGHT WHICH PLEDGOR WOULD
OTHERWISE HAVE UNDER THE CONSTITUTION OR ANY STATUTE OF THE UNITED STATES OR ANY
POLITICAL SUBDIVISION OF ANY SUCH JURISDICTION, and Pledgor hereby further
waives:

                                       11
<PAGE>   301

                  (i)      all damages occasioned by such taking of possession
         except any damages which are the direct result of the gross negligence
         or willful misconduct of either of the Administrative Agent or any
         Person acting on its behalf or instruction;

                  (ii)     all other requirements as to the time, place and
         terms of sale or other requirements with respect to the enforcement of
         the Administrative Agent's rights hereunder; and

                  (iii)    all rights of redemption, appraisement, valuation,
         stay, extension or moratorium now or hereafter in force under any
         Requirements of Law in order to prevent or delay the enforcement of
         this Agreement (including, without limitation, any right to claim that
         such enforcement should be stayed pending the outcome of any other
         action or proceeding (including any arbitration proceeding)) or the
         absolute sale of the Collateral or any portion thereof, and Pledgor,
         for itself and all who may claim under it, insofar as it or they now or
         hereafter lawfully may, hereby waives the benefit of all such
         Requirements of Law.

Any sale of, or the grant of options to purchase, or any other realization upon,
any Collateral shall, to the extent permitted by Requirements of Law, operate to
divest all right, title, interest, claim and demand, either at law or in equity,
of Pledgor therein and thereto, and shall be a perpetual bar both at law and in
equity against Pledgor and against any and all Persons claiming or attempting to
claim the Collateral so sold, optioned or realized upon, or any part thereof,
from, through and under Pledgor.

         SECTION 17. Application of Proceeds. Notwithstanding any other
provision of this Agreement, all moneys collected by the Administrative Agent
upon any sale or other disposition of the Collateral pursuant to Section 16,
together with all other moneys received by the Administrative Agent hereunder,
shall be applied in accordance with the Deposit Account Agreement.

         SECTION 18. Remedies Cumulative. No failure or delay on the part of the
Administrative Agent or any Secured Party in exercising any right, power or
privilege hereunder or under any other Financing Document and no course of
dealing between Pledgor and the Administrative Agent or any Secured Party shall
operate as a waiver thereof; nor shall any single or partial exercise of any
right, power or privilege hereunder or under any other Financing Document
preclude any other or further exercise thereof or the exercise of any other
right, power or privilege hereunder or thereunder. The rights, powers and
remedies herein or in any other Financing Document expressly provided are
cumulative and not exclusive of any rights, powers or remedies which the
Administrative Agent or any Secured Party would otherwise have. No notice to or
demand on Pledgor in any case shall entitle Pledgor to any other or further
notice or demand in similar or other circumstances or constitute a waiver of the
rights of the Administrative Agent or any Secured Party to any other or further
action in any circumstances without notice or demand.

         SECTION 19. Discontinuance of Proceedings. In case the Administrative
Agent shall have instituted any proceeding to enforce any right, power or remedy
under this Agreement by

                                       12
<PAGE>   302

foreclosure, sale or otherwise, and such proceeding shall have been discontinued
or abandoned for any reason or shall have been determined adversely to the
Administrative Agent, then and in every such case Pledgor, the Administrative
Agent and each holder of any of the Secured Obligations shall be restored to
their former positions and rights hereunder with respect to the Collateral
subject to the security interest created under this Agreement, and all rights,
remedies and powers of the Administrative Agent shall continue as if no such
proceeding had been instituted.

         SECTION 20. Indemnity and Expenses. (a) Pledgor agrees to indemnify and
hold harmless the Administrative Agent and each Secured Party from and against
any and all claims, losses and liabilities arising out of or resulting from the
Collateral or Pledgor's pledge and assignment under this Agreement (including,
without limitation, enforcement against Pledgor of this Agreement), except
claims, losses or liabilities resulting from the Administrative Agent's or any
Secured Party's gross negligence or willful misconduct.

         (b)      Pledgor will upon demand pay to the Administrative Agent or
any Secured Party the amount of any and all reasonable expenses, including the
reasonable fees and expenses of its counsel and of any experts and agents, which
the Administrative Agent or any Secured Party may incur in connection with (i)
the administration of this Agreement, (ii) the sale of, collection from, or
other realization upon, any of the Collateral of Pledgor, (iii) the exercise or
enforcement (whether through negotiations, legal proceedings or otherwise) of
any of the rights of the Administrative Agent or any Secured Party hereunder
against Pledgor or (iv) the failure by Pledgor to perform or observe any of the
provisions hereof.

         SECTION 21. Security Interest Absolute. The obligations of Pledgor
under this Agreement are independent of the Secured Obligations, and a separate
action or actions may be brought and prosecuted against Pledgor to enforce this
Agreement, irrespective of whether any action is brought against the Borrower,
any other pledgor or any guarantor of the Secured Obligations or whether the
Borrower, any other pledgor or any guarantor of the Secured Obligations is
joined in any such action or actions. All rights of the Administrative Agent and
the assignment, hypothecation and security interest hereunder, and all
obligations of Pledgor hereunder, shall be absolute and unconditional, to the
extent permitted by applicable law, irrespective of:

         (a)      any lack of validity or enforceability of this Agreement, the
Credit Agreement, any other Financing Document or any other agreement or
instrument relating to any thereof, the absence of any action to enforce the
same, any release of any Borrower Entity or Pledgor, the recovery of any
judgment against any Borrower Entity or Pledgor, any action to enforce the same
or any other circumstance which might otherwise constitute a legal or equitable
discharge or defense of Pledgor;

         (b) any occurrence or condition whatsoever, including without
limitation, (i) any compromise, settlement, release, waiver, renewal, extension,
indulgence or modification of, or any change in, any of the obligations of any
Borrower Entity or Pledgor contained in this Agreement, the Credit Agreement or
any other Financing Document, (ii) any impairment,

                                       13
<PAGE>   303

modification, release or limitation of the liability of any Borrower Entity or
Pledgor or any of their estates in bankruptcy, or any remedy for the enforcement
thereof, resulting from the operation of any present or future provision of any
applicable bankruptcy law, as amended, or other statute or from the decision of
any court, (iii) the assertion or exercise by Pledgor, the Administrative Agent
or any other Secured Party of any rights or remedies, (iv) the assignment or the
purported assignment of any property as security for the Secured Obligations,
including all or any part of the rights of Pledgor under this Agreement, (v) the
extension of the time for payment by any Borrower Entity or any other guarantor
of any payments or other sums or any part thereof owing or payable under any of
the terms and provisions of any Financing Document or of the time for
performance by any Borrower Entity or Pledgor of any other obligations under or
arising out of any terms or provisions or the extension of the renewal of any
thereof, (vi) the modification or amendment (whether material or otherwise) of
any duty, agreement or obligation of any Borrower Entity or Pledgor set forth in
any Financing Document, (vii) the voluntary or involuntary liquidation,
dissolution, sale or other disposition of all or substantially all of the
assets, marshalling of assets and liabilities, receivership, insolvency,
bankruptcy, assignment for the benefit of creditors, reorganization,
arrangement, composition or readjustment of, or other similar proceeding
affecting any Borrower Entity or Pledgor or any of their respective assets, or
the disaffirmancy of this Agreement or any Financing Document in any such
proceeding, (viii) the release or discharge of any Borrower Entity or Pledgor
from the performance or observance of any agreement, covenant, term or condition
contained in any of such instruments by operation of law, (ix) the
unenforceability of this Agreement or any Financing Document or (x) any other
circumstance which might otherwise constitute a legal or equitable discharge of
a surety or guarantor; or

         (c)      any exchange, release or non perfection of any collateral, or
any release or amendment or waiver of or consent to departure from any other
guarantee, for all or any of the Secured Obligations.

         SECTION 22. Amendment; Waiver. No amendment or waiver of any provision
of this Agreement shall be effective unless the same shall be undertaken and
accomplished in accordance with the requirements of Section 9.02 of the Credit
Agreement. No delay on the part of any Secured Party in the exercise of any
right, power or remedy shall operate as a waiver thereof, nor shall any single
or partial waiver by such Secured Party of any right, power or remedy preclude
any further exercise thereof, or the exercise of any other right, power or
remedy.

         SECTION 23. Addresses for Notices. All notices, requests and other
communications to Pledgor or the Administrative Agent shall be in writing
(including bank wire, cable, telex, telecopy or similar teletransmission or
writing) and shall be given, in the case of Pledgor to its address, or telex,
cable or telecopy number set forth on the signature page hereof, and in the case
of the Administrative Agent, to it at its address, or telex, cable or telecopy
number set forth in Annex II to the Credit Agreement or such other address or
telex, cable or telecopy number as each party may hereafter specify by notice to
such other party. Each such notice, request or other communication shall be
effective (i) if given by telex, when such telex is transmitted to the telex
number specified on the signature page hereof or in Annex II, as the case may
be, and the appropriate answerback is received, (ii) if given by telecopy, when
such telecopy is transmitted to the telecopy number specified on the signature
page hereof or in Annex II, as the case may be,

                                       14
<PAGE>   304

and receipt thereof is confirmed in writing, or (iii) if given by any other
means (including, without limitation, by air courier), when delivered at the
address specified on the signature page hereof or in Annex II, as the case may
be.

         SECTION 24. Continuing Assignment, Pledge and Security Interest,
Transfer of Note. This Agreement shall create a continuing pledge, assignment
of, hypothecation of and security interest in the Collateral and shall (i)
remain in full force and effect until no Lender shall have any Commitment
outstanding, and until the Notes, together with interest, and all other Secured
Obligations are indefeasibly paid in full, (ii) be binding upon Pledgor, its
successors and assigns, provided, that Pledgor may not transfer or assign any or
all of its rights or obligations hereunder without the prior written consent of
each Lender, and (iii) inure to the benefit of, and be enforceable by, the
Administrative Agent, the Secured Parties and their respective successors,
transferees and assigns. Without limiting the generality of the foregoing clause
(iii), any Secured Party may assign or otherwise transfer all or any portion of
its rights in the Secured Obligations to the extent and in the manner provided
in the Credit Agreement, and such assignee shall thereupon become vested with
all the benefits in respect thereof granted to such Secured Party herein or
otherwise. Upon the indefeasible payment in full of the Secured Obligations and
the expiration or termination of the Commitments, the security interest granted
hereby shall terminate and all rights to the Collateral shall revert to Pledgor.
Upon any such termination, the Administrative Agent will, at Pledgor's expense,
execute and deliver to Pledgor such documents including UCC termination
statements as Pledgor shall reasonably request to evidence such termination.

         SECTION 25. Severability. Any provision hereof that is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof and without affecting the validity or enforceability
of any provision in any other jurisdiction.

         SECTION 26. GOVERNING LAW; TERMS. THIS AGREEMENT SHALL BE GOVERNED BY
AND INTERPRETED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK OTHER THAN
ANY SUCH REQUIREMENT OF LAWS THAT WOULD APPLY THE LAWS OF ANOTHER JURISDICTION,
EXCEPT TO THE EXTENT THAT THE LAWS OF ANOTHER JURISDICTION ARE MANDATORILY
APPLICABLE AND EXCEPT TO THE EXTENT THAT THE VALIDITY OR PERFECTION OF THE
SECURITY INTEREST HEREUNDER, OR REMEDIES HEREUNDER, IN RESPECT OF ANY PARTICULAR
COLLATERAL ARE GOVERNED BY THE LAWS OF A JURISDICTION OTHER THAN THE STATE OF
NEW YORK. UNLESS OTHERWISE DEFINED HEREIN OR IN THE CREDIT AGREEMENT, TERMS USED
IN ARTICLE 9 OF THE NY UCC ARE USED HEREIN AS THEREIN DEFINED. ANY DISPUTE
ARISING OUT OF, CONNECTED WITH, RELATED TO, OR INCIDENTAL TO THE RELATIONSHIP
ESTABLISHED BETWEEN THE PLEDGOR AND EACH SECURED PARTY IN CONNECTION WITH THIS
AGREEMENT AND THE OTHER FINANCING DOCUMENTS, AND WHETHER ARISING IN CONTRACT,
TORT, EQUITY OR OTHERWISE, SHALL BE RESOLVED IN ACCORDANCE WITH THE INTERNAL
LAWS (AS OPPOSED TO THE CONFLICTS OF LAWS PROVISIONS) AND DECISIONS OF THE STATE
OF NEW YORK.

         SECTION 27. CONSENT TO JURISDICTION; WAIVER OF JURY TRIAL. (a) PLEDGOR
AND EACH SECURED PARTY AGREE THAT ALL DISPUTES BETWEEN THEM ARISING OUT OF,
CONNECTED WITH, RELATED TO, OR INCIDENTAL TO THE RELATIONSHIP ESTABLISHED
BETWEEN THEM IN CONNECTION WITH THIS AGREEMENT AND THE OTHER FINANCING
DOCUMENTS, AND WHETHER ARISING IN CONTRACT, TORT, EQUITY, OR OTHERWISE, SHALL BE
RESOLVED ONLY BY STATE OR FEDERAL COURTS LOCATED IN NEW YORK, NEW YORK, BUT
PLEDGOR AND EACH SECURED PARTY ACKNOWLEDGE THAT ANY APPEALS FROM THOSE COURTS
MAY HAVE TO BE HEARD BY A COURT LOCATED OUTSIDE OF NEW YORK, NEW YORK. PLEDGOR
WAIVES IN ALL DISPUTES ANY OBJECTION THAT IT MAY HAVE TO THE LOCATION OF THE
COURT CONSIDERING THE DISPUTE INCLUDING, WITHOUT LIMITATION, ANY OBJECTION TO
THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS.

(b)      PLEDGOR AND THE SECURED PARTIES EACH WAIVE ANY RIGHT TO HAVE A JURY
PARTICIPATE IN RESOLVING ANY DISPUTE, WHETHER SOUNDING IN CONTRACT, TORT, OR
OTHERWISE ARISING OUT OF, CONNECTED WITH, RELATED TO OR INCIDENTAL TO THE
RELATIONSHIP ESTABLISHED BETWEEN THEM IN CONNECTION WITH THIS AGREEMENT AND THE
OTHER FINANCING DOCUMENTS. INSTEAD, ANY DISPUTES RESOLVED IN COURT WILL BE
RESOLVED IN A BENCH TRIAL WITHOUT A JURY.

         SECTION 28. Execution in Counterparts. This Agreement may be executed
in any number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed shall be deemed to be an original
and all of which taken together shall constitute one and the same instrument.

         SECTION 29. Limitation on Recourse. The obligations of Pledgor
hereunder are obligations solely of Pledgor and shall not constitute a debt or
obligation of any direct or indirect partner or shareholder of Pledgor or any of
their respective directors, officers, agents or employees (each such Person, a
"Non Recourse Party"). No Non Recourse Party shall be liable for any amount
payable by Pledgor under this Agreement and the Secured Parties shall not seek a
money judgment or deficiency or personal judgment against any Non Recourse Party
for payment of the indebtedness payable by Pledgor evidenced by this Agreement.
No property or assets of any Non Recourse Party, other than as contemplated in
the Financing Documents, shall be sold, levied upon or otherwise used to satisfy
any judgment rendered in connection with any action brought against Pledgor with
respect to this Agreement or the other Financing Documents. The foregoing
acknowledgments, agreements and waivers shall be enforceable by any Non Recourse
Party. Notwithstanding the foregoing, nothing in this Section shall limit or
affect or be construed to limit or affect the obligations and liabilities of any
Credit Party or any other Non Recourse Party (a) in accordance with the terms of
any Transaction Document or Financing Document creating such liabilities and
obligations to which such Credit Party or Non Recourse Party is a party, (b)
arising from liability pursuant to applicable Requirements of Law for such
Credit Party's or such Non Recourse Party's fraudulent actions, knowing
misrepresentations or willful misconduct or (c) with respect to amounts
distributed to it in violation of Section 6.10 of the Credit Agreement.

                          INTERCOMPANY ACQUISITION NOTE

[$700,000,000]

         FOR VALUE RECEIVED, the undersigned, __________________, a limited
partnership organized under the laws of the State of Delaware (the "Maker"),

any party primarily or secondarily liable hereon and (iv) that it will not be
necessary for the Payee, or any of its successors or assigns, in order to
enforce payment of this Note, to

first institute or exhaust their remedies against the Maker or any other party
liable therefor or against any security for this Note. The nonexercise by the
holder of any of its rights hereunder in any particular instance shall not
constitute a waiver thereof in that or any subsequent instance.

         The outstanding principal balance of the loans and advances evidenced
by this Note shall automatically become immediately due and payable, without
presentment, demand, protest or any other notice of any kind, all of which are
expressly waived by the Maker, upon occurrence of an Event of Default under the
Credit Agreement and any acceleration of the maturity of the Obligations,
unless, however, such acceleration has been stayed, prevented or otherwise
frustrated for any reason, in which event, solely upon the occurrence of an
Event of Default under the Credit Agreement.

         The Payee hereby subordinates in right of payment all indebtedness of
the Maker owing to it, whether originally contracted with the Payee or acquired
by the Payee by assignment, transfer or otherwise, whether now owed or hereafter
arising, whether for principal, interest, fees, expenses or otherwise, together
with all renewals, extensions, increases or rearrangements thereof, to the prior
indefeasible payment in full in cash of the Obligations (as defined in the
Credit Agreement), whether now owed or hereafter arising, whether for principal,
interest (including interest accruing after the filing of a petition initiating
any proceeding referred to in Section 7.07 of the Credit Agreement), fees,
expenses or otherwise together with all renewals, extensions, increases or
rearrangements thereof.

         This Note shall be construed in accordance with and governed by the
laws of the State of New York and any applicable laws of the United States of
America.

         In the event this Note is not paid when due at any stated or
accelerated maturity, the Maker agrees to pay, in addition to the principal of
and interest on this Note, all costs of collection, including reasonable
attorneys' fees.

[$                  ]

         FOR VALUE RECEIVED, the undersigned, __________________, a limited

below, all as recorded either on the grid attached to this Note or in the
records of the Payee; provided, however, that the failure to make any such

Maker's obligation to repay this Note. This Note may be prepaid in whole or in
part at any time without premium or penalty. Amounts prepaid on this Note may be
reborrowed. Terms used herein and not otherwise defined herein shall have the
meanings assigned to them in the Credit Agreement dated as of July 28, 1999 (as

hereto, and agree (i) to all extensions and partial payments, with or without
notice before or after maturity, (ii) to any substitution, exchange or release
of any security now or hereafter given for this Note, (iii) to the release of
any party primarily or secondarily liable hereon and (iv) that it will not be
necessary for the Payee, or any of its successors or assigns, in order to
enforce payment of this Note, to first institute or exhaust their remedies
against the Maker or any other party liable therefor or against any security for
this Note. The nonexercise by the holder of any of its rights hereunder in any
particular instance shall not constitute a waiver thereof in that or any
subsequent instance.

presentment, demand, protest or any other notice of any kind, all of which are
expressly waived by the Maker, upon occurrence of an Event of Default under the
Credit Agreement and any acceleration of the maturity of the Obligations,
unless, however, such acceleration has been stayed, prevented or otherwise
frustrated for any reason, in which event, solely upon the occurrence of an
Event of Default under the Credit Agreement.

         The Payee hereby subordinates in right of payment all indebtedness of
the Maker owing to it, whether originally contracted with the Payee or acquired
by the Payee by assignment, transfer or otherwise, whether now owed or hereafter
arising, whether for principal, interest, fees, expenses or otherwise, together

America.

         THIS SUBSIDIARY GUARANTEE AGREEMENT (this "Guarantee Agreement") is
dated as of July 28, 1999, among ERIE BOULEVARD HYDROPOWER, L.P., a Delaware
limited partnership ("Erie"), CARR STREET GENERATING STATION, L.P., a Delaware
limited partnership ("Carr Street") and such other Subsidiaries as shall become
parties hereto in accordance with Section 16 hereof (Erie, Carr Street and such
other Subsidiaries being referred to herein individually as a "Guarantor" and
collectively as the "Guarantors") and BANK OF AMERICA, N.A., as Administrative
Agent (in such capacity, the "Administrative Agent") for the Secured Parties.

         Reference is made to that certain Credit Agreement, dated as of July
28, 1999 (as amended, supplemented or otherwise modified from time to time, the
"Credit Agreement"), among Orion Power New York, L.P. (the "Borrower"), Banc of
America Securities LLC and Paribas, as lead arrangers (the "Lead Arrangers"),
the financial institutions from time to time signatories thereto (the
"Lenders"), Bank of America, N.A., as Issuing Bank, and the Administrative
Agent, pursuant to which the Lenders have agreed to extend credit to the
Borrower upon the terms and subject to the conditions set forth therein. Terms
used herein and not otherwise defined herein shall have the meanings assigned to
them in the Credit Agreement.

         The Lenders have respectively agreed to extend credit to the Borrower
upon the terms and subject to the conditions set forth in the Credit Agreement.
The obligations of the Lenders to extend credit under the Credit Agreement are
conditioned on, among other things, the execution and delivery by the Guarantors
of a Guarantee Agreement in the form hereof. The proceeds of the credit extended
to the Borrower under the Credit Agreement will be extended to the Subsidiaries
to finance the Subsidiaries' acquisition of certain power generation assets
described in the Credit Agreement and will, in part, enable the Borrower to
provide the Subsidiaries with working capital pursuant to the Intercompany
Working Capital Note. As Subsidiaries, the Guarantors acknowledge that they will
derive substantial benefits from the extension of credit to the Borrower under
the Credit Agreement. As consideration therefor and in order to induce the
Lenders to make Loans and issue the ConEd Letter of Credit, the Guarantors are
willing to execute and deliver this Guarantee Agreement.

         Accordingly, the Guarantors, intending to be legally bound, hereby
agree with the Administrative Agent, for the ratable benefit of the Secured
Parties, as follows:

         SECTION 1. Guarantee. Subject to Section 15 hereof, each of the
Guarantors unconditionally guarantees, jointly with the other Guarantors and
severally, as a primary obligor and not merely as a surety, the due and punctual
payment by the Borrower of (a) the principal of and interest (including interest
accruing after the filing of a petition initiating any proceeding referred to in
Section 7.07 of the Credit Agreement) on the Loans and all amounts drawn under
the ConEd Letter of Credit, when and as due and payable, whether at maturity, by
acceleration, upon one or more dates set for prepayment or otherwise, (b) each
payment required to be made by the Borrower under any Interest Hedge Contract
entered into by the Borrower with any Lender, and (c) all other Obligations of
the Borrower to the Secured Parties under the Credit Agreement and the other
Financing Documents (all the foregoing obligations being collectively called the
"Guaranteed Obligations"), and agrees to pay any and all expenses (including

                                       1
<PAGE>   320

reasonable counsel fees and expenses) incurred in enforcing any rights under
this Guarantee Agreement.

         SECTION 2. Guarantee Absolute. (a) Each Guarantor guarantees that the
Guaranteed Obligations will be paid strictly in accordance with the terms of the
Financing Documents, regardless of any law, regulation or order now or hereafter
in effect in any jurisdiction affecting any of such terms or the rights of the
Secured Parties with respect thereto. The obligations of the Guarantors under
this Guarantee Agreement are independent of the Guaranteed Obligations, and a
separate action or actions may be brought and prosecuted against each Guarantor
to enforce this Guarantee Agreement, irrespective of whether any action is
brought against the Borrower or any other Guarantor or whether the Borrower or
any other Guarantor is joined in any such action or actions. This Guarantee
Agreement is an absolute and unconditional guaranty of payment when due, and not
of collection, by each Guarantor, jointly and severally with any other Guarantor
of the Guaranteed Obligations in each and every particular. The obligations of
each Guarantor hereunder are several from those of the Borrower and are primary
obligations concerning which each Guarantor is the principal obligor. The
Secured Parties shall not be required to mitigate damages or take any action to
reduce, collect or enforce the Guaranteed Obligations.

         (b)      This Guarantee Agreement shall continue to be effective or be
reinstated, as the case may be, if at any time any payment of any of the
Guaranteed Obligations is rescinded or must otherwise be returned by the
Administrative Agent or any other Secured Party upon the insolvency, bankruptcy
or reorganization of the Borrower or otherwise, all as though such payment had
not been made.

         (c)      The obligations of each Guarantor hereunder shall not be
subject to any reduction, limitation, impairment or termination for any reason,
including the existence of any claim, set-off or other right which any Guarantor
may have at any time against the Borrower or any other Guarantor, the
Administrative Agent or other Secured Party or any other corporation or person,
whether in connection herewith or any unrelated transactions; provided, that,
nothing herein shall prevent the assertion of any such claim by separate suit or
counterclaim. Without limiting the generality of the foregoing, each Guarantor's
liability shall extend to all amounts that constitute part of the Guaranteed
Obligations and would be owed by the Borrower to any Secured Party under the
Financing Documents but for the fact that they are unenforceable or not
allowable due to the existence of a bankruptcy, reorganization or similar
proceeding involving the Borrower.

         SECTION 3. Waivers. Each Guarantor hereby waives presentment to, demand
of payment from and protest to the Borrower or any other Guarantor of any of the
Guaranteed Obligations, and also waives promptness, diligence, notice of
acceptance of its guarantee, any other notice with respect to any of the
Guaranteed Obligations and this Guarantee Agreement and any requirement that the
Administrative Agent or any other Secured Party protect, secure, perfect or
insure any Lien or any property subject thereto. Each Guarantor further waives
any right to require that resort be had by the Administrative Agent or any other
Secured Party to any security held for payment of the Guaranteed Obligations or
to any balance of any deposit, account or credit on the books of the
Administrative Agent or any other Secured Party in favor of the Borrower or any
other person. Each Guarantor hereby consents and agrees to each of the

                                       2
<PAGE>   321
following to the fullest extent permitted by Requirements of Law, and agrees to
the fullest extent permitted by Requirements of Law that such Guarantor's
obligations under this Guarantee Agreement shall not be released, diminished,
impaired, reduced or adversely affected by any of the following, and waives any
rights (including rights to notice) which such Guarantor might otherwise have as
a result of or in connection with any of the following:

         (a)      any renewal, extension, modification, increase, decrease,
     alteration or rearrangement of all or any part of the Guaranteed
     Obligations or any instrument executed in connection therewith, or any
     contract or understanding with the Borrower, the Administrative Agent, the
     other Secured Parties, or any of them, or any other person, pertaining to
     the Guaranteed Obligations;

         (b)      any adjustment, indulgence, forbearance or compromise that
     might be granted or given by the Administrative Agent or any other Secured
     Party to the Borrower or any Guarantor or any person liable on the
     Guaranteed Obligations; or the failure of the Administrative Agent or any
     other Secured Party to assert any claim or demand or to exercise any right
     or remedy against the Borrower or any Guarantor under the provisions of any
     Financing Document or otherwise; or any rescission, waiver, amendment or
     modification of, or any release from any of the terms or provisions of, any
     Financing Document, any guarantee or any other agreement, including with
     respect to any other Guarantor under this Guarantee Agreement;

         (c)      the insolvency, bankruptcy arrangement, adjustment,
     composition, liquidation, disability, dissolution or lack of power of the
     Borrower or any Guarantor or any other person at any time liable for the
     payment of all or part of the Guaranteed Obligations; or any dissolution of
     the Borrower or any Guarantor, or any change, restructuring or termination
     of the corporate structure or existence of the Borrower or any Guarantor,
     or any sale, lease or transfer of any or all of the assets of the Borrower
     or any Guarantor, or any change in the shareholders, partners, or members
     of the Borrower or any Guarantor; or any default, failure or delay, willful
     or otherwise, in the performance of the Guaranteed Obligations;

         (d)      the invalidity, illegality or unenforceability of all or any
     part of the Guaranteed Obligations, or any document or agreement executed
     in connection with the Guaranteed Obligations, for any reason whatsoever,
     including the fact that the Guaranteed Obligations, or any part thereof,
     exceed the amount permitted by law, the act of creating the Guaranteed
     Obligations or any part thereof is ultra vires, the officers or
     representatives executing the documents or otherwise creating the
     Guaranteed Obligations acted in excess of their authority, the Guaranteed
     Obligations violate applicable usury laws, the Borrower has valid defenses,
     claims or offsets (whether at law, in equity or by agreement) which render
     the Guaranteed Obligations wholly or partially uncollectible from the
     Borrower, the creation, performance or repayment of the Guaranteed
     Obligations (or the execution, delivery and performance of any document or
     instrument representing part of the Guaranteed Obligations or executed in
     connection with the Guaranteed Obligations or given to secure the repayment
     of the Guaranteed

                                       3
<PAGE>   322

     Obligations) is illegal, uncollectible, legally impossible or
     unenforceable, or the documents or instruments pertaining to the Guaranteed
     Obligations have been forged or otherwise are irregular or not genuine or
     authentic;

         (e)      any full or partial release of the liability of the Borrower
     on the Guaranteed Obligations or any part thereof, of any co-guarantors, or
     of any other person now or hereafter liable, whether directly or
     indirectly, jointly, severally, or jointly and severally, to pay, perform,
     guarantee or assure the payment of the Guaranteed Obligations or any part
     thereof, it being recognized, acknowledged and agreed by each Guarantor
     that such Guarantor may be required to pay the Guaranteed Obligations in
     full without assistance or support of any other person, and such Guarantor
     has not been induced to enter into this Guarantee Agreement on the basis of
     a contemplation, belief, understanding or agreement that any parties other
     than the Borrower will be liable to perform the Guaranteed Obligations, or
     that the Secured Parties will look to other parties to perform the
     Guaranteed Obligations;

         (f)      the taking or accepting of any other security, collateral or
     guaranty, or other assurance of payment, for all or any part of the
     Guaranteed Obligations;

         (g)      any release, surrender, exchange, subordination,
     deterioration, waste, loss or impairment (including negligent, unreasonable
     or unjustifiable impairment) of any letter of credit, collateral, property
     or security, at any time existing in connection with, or assuring or
     securing payment of, all or any part of the Guaranteed Obligations;

         (h)      the failure of the Administrative Agent, any other Secured
     Party or any other person to exercise diligence or reasonable care in the
     preservation, protection, enforcement, sale or other handling or treatment
     of all or any part of such collateral, property or security;

         (i)      the fact that any collateral, security, security interest or
     lien contemplated or intended to be given, created or granted as security
     for the repayment of the Guaranteed Obligations shall not be properly
     perfected or created, or shall prove to be unenforceable or subordinate to
     any other security interest or lien, it being recognized and agreed by each
     Guarantor that such Guarantor is not entering into this Guarantee Agreement
     in reliance on, or in contemplation of the benefits of, the validity,
     enforceability, collectibility or value of any of the Collateral;

         (j)      any payment by the Borrower to the Administrative Agent or any
     other Secured Party being held to constitute a preference under Title 11 of
     the United States Code or any similar Federal or state law, or for any
     reason the Administrative Agent or any other Secured Party being required
     to refund such payment or pay such amount to the Borrower or someone else;

         (k)      any other action taken or omitted to be taken with respect to
     the Guaranteed Obligations, or the security and collateral therefor,
     whether or not such action

                                       4
<PAGE>   323

         or omission prejudices any Guarantor or increases the likelihood that
         any Guarantor will be required to pay the Guaranteed Obligations
         pursuant to the terms hereof, it being the unambiguous and unequivocal
         intention of each Guarantor that such Guarantor shall be obligated to
         pay the Guaranteed Obligations when due, notwithstanding any
         occurrence, circumstance, event, action or omission whatsoever, whether
         or not contemplated, and whether or not otherwise or particularly
         described herein, except for the full and indefeasible payment and
         satisfaction of the Guaranteed Obligations in cash;

                  (l)      the fact that all or any of the Guaranteed
         Obligations cease to exist by operation of law, including by way of a
         discharge, limitation or tolling thereof under applicable bankruptcy
         laws; or

                  (m)      any other circumstance (including any statute of
         limitations) that might in any manner or to any extent otherwise
         constitute a defense (other than a defense of indefeasible payment and
         performance in full of the Guaranteed Obligations) available to, vary
         the risk of, or operate as a discharge of, the Borrower or any
         Guarantor as a matter of law or equity.

All waivers herein contained shall be without prejudice to the Administrative
Agent at its option to proceed against the Borrower, any Guarantor or any other
person, whether by separate action or by joinder.

         SECTION 4. Security for Guarantee. Each of the Guarantors authorizes
the Administrative Agent, in accordance with the terms and subject to the
conditions set forth in the Security Documents, (a) to take and hold security
for the payment of this Guarantee Agreement and the Guaranteed Obligations and
to exchange, enforce, waive and release any such security, (b) to apply such
security and direct the order or manner of sale thereof as the Administrative
Agent in its reasonable discretion may determine in accordance with the
Financing Documents and (c) to release or substitute any one or more endorsees,
other guarantors or other obligors. The Administrative Agent may, at its
election, in accordance with the terms and subject to the conditions set forth
in the Security Documents, foreclose on any security held by it by one or more
judicial or nonjudicial sales, or exercise any other right or remedy available
to it against the Borrower or any of the Guarantors, or any security, without
affecting or impairing in any way the liability of any of the Guarantors
hereunder, except to the extent the Guaranteed Obligations have been
indefeasibly paid in full in cash.

         SECTION 5. Subrogation. In furtherance of the foregoing and not in
limitation of any other right which the Administrative Agent or any other
Secured Party has at law or in equity against any Guarantor by virtue hereof,
upon the failure of the Borrower or any Guarantor to pay any Guaranteed
Obligation when and as the same shall become due, whether at maturity, by
acceleration, after notice of prepayment or otherwise, each of the Guarantors
hereby promises to and will, upon receipt of written demand by the
Administrative Agent, forthwith pay, or cause to be paid, to the Administrative
Agent for distribution to the Lenders and the other Secured Parties, if and as
appropriate, in cash the amount of such unpaid Guaranteed Obligation. No
Guarantor shall exercise any claims or rights which it may now have or hereafter
acquire against the

                                       5
<PAGE>   324

Borrower that arise from the existence, payment, performance or enforcement of
such Guarantor's obligations under this Guarantee Agreement or any other
Financing Documents, including any right of subrogation, reimbursement,
exoneration, contribution or indemnification and any right to participate in any
claim or remedy of the Administrative Agent or any other Secured Party against
the Borrower or any Collateral, whether or not such claim, remedy or right
arises in equity or under contract, statute or common law, including the right
to take or receive from the Borrower directly or indirectly, in cash or other
property or by setoff or any other manner, payment or security on account of
such claim, remedy or right. If any amount shall be paid to any Guarantor in
violation of the preceding sentence at any time prior to the later of (a) the
indefeasible cash payment in full of the Guaranteed Obligations and all other
amounts payable under this Guarantee Agreement and (b) the termination of the
Commitments, such amount shall be held in trust for the benefit of the
Administrative Agent and the other Secured Parties and shall forthwith be paid
to the Administrative Agent to be credited and applied to the Guaranteed
Obligations and all other amounts payable under this Guarantee Agreement,
whether matured or unmatured, in accordance with the terms of the Financing
Documents, or to be held as Collateral for any Guaranteed Obligations or other
amounts payable under this Guarantee Agreement thereafter arising. Each
Guarantor acknowledges that it will receive direct and indirect benefits from
the financing arrangements contemplated by the Financing Documents and that the
waiver set forth in this Section 5 is knowingly made in contemplation of such
benefits.

         SECTION 6. Representations and Warranties. Each Guarantor hereby
represents and warrants as follows:

         (a)      Existence; Due Qualification; Compliance With Law. Each
Guarantor (a) is duly formed, validly existing and in good standing under the
laws of the respective jurisdiction of its formation, (b) has all requisite
power and authority to own its property and assets, to borrow money and to
transact the business in which it is presently engaged and in which it proposes
to be engaged, (c) has duly qualified and is authorized to do business and is in
good standing in every jurisdiction where the character of its properties or the
nature of its activities makes such qualification necessary and (d) is in full
compliance with its Governing Documents, all Contractual Obligations, all
applicable Requirements of Law and all Governmental Approvals, except to the
extent that the failure to comply therewith could not reasonably be expected to
have a Material Adverse Effect

         (b)      Power; Authority; No Violation; Binding Effect. The execution,
delivery and performance by the Guarantors of the Transaction Documents to which
each is a party and the consummation of the transactions contemplated thereby
(i) are within their respective powers, (ii) have been duly authorized by all
necessary corporate or partnership action, (iii) do not and will not contravene
(A) their respective Governing Documents or (B) any material Requirement of Law,
any material Contractual Obligation or any material Governmental Approval
binding on or affecting any of them and (iv) do not and will not conflict with
or be inconsistent with or result in any breach of any of the terms, covenants,
conditions or provisions of, or constitute a default under, or result in the
creation or imposition of (or the obligation to create or impose) any Lien
(except Permitted Liens) upon any of their respective properties or assets
pursuant to, the terms of any material Contractual Obligation binding on or
affecting any of them.

                                       6
<PAGE>   325

         (c)      Due Execution and Delivery. Each Guarantor has duly executed
and delivered each Transaction Document to which it is a party. Each Transaction
Document constitutes the legal, valid and binding obligation of each Guarantor
(to the extent it is a party thereto), enforceable against such Borrower Entity
in accordance with its terms, except as enforcement thereof may be subject to
(i) the effect of any applicable bankruptcy, insolvency, reorganization,
moratorium or similar laws affecting creditors' rights generally and (ii)
general principles of equity.

         (d)      Ownership of Property. Except as set forth on Schedule 4.03 to
the Credit Agreement, each Guarantor has good title to, or valid leasehold,
easement or right-of-way interests in, the material property, assets or revenues
which it purports to own, lease or hold any such interest in, free and clear of
all Liens (except Permitted Liens), including possession of all required real
estate interests and licenses, Intellectual Property and other proprietary
rights.

         (e)      Governmental Approvals. Except as otherwise set forth on
Schedule 4.04 attached to the Credit Agreement, no Governmental Approval or
approval of any other Person (except such as have been duly obtained, made or
given, and are in full force and effect) is required to authorize, or is
required in connection with (a) the execution, delivery or performance of any
Transaction Document by any Guarantor or the consummation of any of the
transactions contemplated thereby (including, without limitation, the purchase
of the Portfolio Assets and the granting of Liens pursuant to the Security
Documents), (b) the ownership, maintenance or operation of the Portfolio Assets
by the relevant Guarantor or (c) the legality, validity, binding effect or
enforceability of any Transaction Document. Except as otherwise set forth on
Schedule 4.04 attached to the Credit Agreement, all applicable waiting periods
(including appeal periods) relating to any such Governmental Approval or other
approval which are required and have been obtained have expired without any
adverse action taken with respect thereto.

         (f)      Solvency. Each Guarantor is and, after consummation of the
transactions and performance of the obligations contemplated by this Agreement,
will be Solvent. As used herein, "Solvent" shall mean, with respect to any
Person as of a particular date, that on such date (i) such Person is able to
realize upon its assets and pay its debts and other liabilities, contingent
obligations and other commitments as they mature in the normal course of
business, (ii) such Person does not intend to, and does not believe that it
will, incur debts or liabilities beyond such Person's ability to pay such debts
and liabilities as they mature in their ordinary course, taking into account the
timing of and amounts of cash to be received by such Person and the timing of
and amounts of cash to be payable on or in respect of debts and liabilities of
such Person, (iii) such Person is not engaged in a business or a transaction,
and is not about to engage in a business or a transaction, for which such
Person's property would constitute unreasonably small capital after giving due
consideration to the industry in which such Person is engaged or is to engage,
(iv) the fair value of the property of such Person is greater than the total
amount of liabilities, including contingent liabilities, of such Person and (v)
the present fair salable value of the assets of such Person is not less than the
amount that will be required to pay the probable liability of such Person on its
debts and liabilities as they become absolute and matured. In computing the
amount of contingent liabilities at any time, it is intended that such
liabilities will be computed at

                                       7
<PAGE>   326

the amount which, in light of all the facts and circumstances existing at such
time, represents the amount that can reasonably be expected to become an actual
or matured liability.

         (g)      There are no conditions precedent to the effectiveness of this
Guarantee Agreement that have not been satisfied or waived.

         (h)      Such Guarantor has, independently and without reliance upon
the Administrative Agent or any other Secured Party and based on such documents
and information as it has deemed appropriate, made its own credit analysis and
decision to enter into this Guarantee Agreement. Such Guarantor has investigated
fully the benefits and advantages which will be derived by it from execution of
this Guarantee Agreement, and the Board of Directors of the general partner of
such Guarantor has decided that a direct or an indirect benefit will accrue to
such Guarantor by reason of the execution of this Guarantee Agreement.

         (i)      (i) This Guarantee Agreement is not given with actual intent
to hinder, delay or defraud any person to which such Guarantor is or will
become, on or after the date hereof, indebted; (ii) such Guarantor has received
at least a reasonably equivalent value in exchange for the giving of this
Guarantee Agreement; (iii) such Guarantor is not engaged in a business or
transaction, nor is about to engage in a business or transaction, for which any
property remaining with such Guarantor constitutes an unreasonably small amount
of capital; and (iv) such Guarantor does not intend to incur debts that will be
beyond such Guarantor's ability to pay as such debts mature.

         SECTION 7. Affirmative Covenants. Each Guarantor covenants and agrees
that, so long as this Agreement is in effect and any Lender shall have any
Commitment outstanding hereunder, and until the Notes, together with interest,
and all other Obligations are indefeasibly paid in full and the ConEd Letter of
Credit has been cancelled or has expired and all amounts drawn thereunder have
been indefeasibly reimbursed in full, such Guarantor will:

                  Section 7.01 Conduct of Business; Maintenance of Existence.
(a) Engage solely in the business of owning, operating, maintaining and managing
its interests in the Portfolio Assets which such Guarantor owns, (b) preserve
and maintain in full force and effect its existence as a limited partnership
under the laws of the state of Delaware and its qualification to do business in
every jurisdiction where the character of its properties or the nature of its
activities makes such qualification necessary, (c) preserve and maintain all of
its rights, privileges and franchises necessary for the ownership of its
interest in the Portfolio Assets which such Guarantor owns, in accordance with
the Transaction Documents and (d) subject to Section 6.11 of the Credit
Agreement, keep all property useful and necessary in its business in good
working order and condition (except to the extent that any such property is no
longer required for the business of such Guarantor), ordinary wear and tear
excepted. No Guarantor shall amend its respective Governing Documents in any
manner, the result of which would be to alter the distribution, nature of
business, management, transfer of interests or powers of the general partner
provisions thereof.

                                       8
<PAGE>   327

                  Section 7.02 Governmental Approvals. Duly obtain on, or prior
to, such date as the same may be legally required, and thereafter maintain in
effect as long as legally required, all Governmental Approvals required to be
obtained by such Guarantor under Section 4.04 of the Credit Agreement, except to
the extent the failure to so obtain or maintain could reasonably be expected to
result in a Material Adverse Effect.

                  Section 7.03 Payment of Indebtedness. Pay, discharge or
otherwise satisfy at or before maturity or before they become delinquent, as the
case may be, all of its Obligations and other Indebtedness and obligations of
whatever nature (except for any Indebtedness (other than the Obligations) or
other obligations which are being contested in good faith and by appropriate
proceedings if (a) Acceptable Reserves have been established, and (b) such
contest does not involve any unreasonable risk of the sale, forfeiture or loss
of any of the right, title estate and interest of such Guarantor in any material
Portfolio Asset, taking into account the existence of such Acceptable Reserves).

                  Section 7.04 Accounts. Maintain all of its Accounts with the
Administrative Agent in accordance with the Deposit Account Agreement and the
other Financing Documents and apply, or cause the application of, all amounts on
deposit therein from time to time as required by the Financing Documents.

                  Section 7.05 Performance of Covenants, Etc. Perform and
observe all material Contractual Obligations, including all of the covenants and
agreements contained in the Project Contracts to which it is a party and shall
enforce (including, as necessary, through negotiation, litigation or other
reasonable means) the material rights granted to it under and in connection with
each of the Transaction Documents.

                  Section 7.06 Insurance Requirements. Procure and maintain
insurance against physical loss, public liability, property damage, general
liability, business interruption, environmental risk and other insurance, with
coverages and limits in no event less than those required to be maintained by
such Guarantor, as set forth on Schedule 5.06 to the Credit Agreement (and in
conformance with the requirements set forth thereon). Each Guarantor shall
timely pay all premiums due under all insurance policies required to be
maintained by such Guarantor under Section 5.06 of the Credit Agreement.

                  Section 7.07 Books and Records. Keep proper books of records
and accounts in which full, true and correct entries shall be made of all of its
transactions in accordance with GAAP.

                  Section 7.08 Visitation, Inspection, etc. Permit
representatives of the Administrative Agent, the Independent Engineer and the
Lead Arrangers (at the cost and expense of such Guarantor so long as any Default
or Event of Default exists), and any other Lender (at the cost and expense of
such Lender) to visit and inspect any of its Portfolio Assets, to examine its
books and records and to make copies and take extracts therefrom, and to discuss
its affairs, finances and accounts with its officers and employees and its
independent accountants, all with reasonable prior notice and at such reasonable
times as such Person may reasonably request and

                                       9

subject to such Guarantor's reasonable rules and procedures regarding operation,
safety and confidentiality.

all Requirements of Law and Governmental Approvals (a) applicable to it and such
Guarantor's portion of the Portfolio Assets, including all Environmental Laws

Approval is being contested in good faith and by appropriate proceedings and for
which Acceptable Reserves have been established.

     Guarantor during the relevant fiscal period and that such review has not,

respect to any Operating Budget, if the Administrative Agent fails to approve
such Operating Budget or provides notice to such Guarantor that it rejects all
or any portion of such Operating Budget, such Guarantor and the Administrative
Agent (in consultation with the Independent Engineer) agree to work in good
faith to resolve such dispute; and provided, further, that if an Operating
Budget is not adopted and approved on or prior to the first day of any calendar
year, Guarantors shall adhere to the Interim Operating Budget until such time as
an Operating Budget is adopted and approved by the Administrative Agent (in
consultation with the Independent Engineer).

         (b)      Operate and maintain its portion of the Portfolio Assets or
cause its portion of the Portfolio Assets to be operated and maintained, in

     SECTION 15. Contribution. In order to provide for just and equitable
contribution among the Guarantors, the Guarantors agree that, to the extent any
Guarantor makes any payment hereunder on any date which, when added to all
preceding payments made by such Guarantor hereunder, would result in the
aggregate payments by such Guarantor hereunder exceeding its Percentage (as
defined below) of all payments then or theretofore made by all Guarantors
hereunder, such Guarantor shall have a right of contribution against each other
Guarantor whose aggregate payments then or theretofore made hereunder are less
than its Percentage of all payments by all Guarantors then or theretofore made
hereunder, in an amount such that, after giving effect to any such contribution
rights, each Guarantor will have paid only its Percentage of all payments by all
Guarantors then or theretofore made hereunder. A Guarantor's "Percentage" on any
date shall mean the percentage obtained by dividing (a) the Adjusted Net Assets
of such Guarantor on such date by (b) the sum of the Adjusted Net Assets of all
the Guarantors on such date. "Adjusted Net Assets" means, for each Guarantor on
any date, the lesser of (i) the amount by which the fair value of the property
of such Guarantor exceeds the total amount of liabilities, including contingent
liabilities, but excluding liabilities under this Guarantee Agreement, of such
Guarantor on such date and (ii) the amount by which the present fair salable
value of the assets of such Guarantor on such date exceeds the amount that will
be required to pay the probable liability of such Guarantor on its debts,
excluding debt in respect of this Guarantee Agreement, as they become absolute
and matured. The provisions set forth in this Section 14 are for the sole
benefit of the Guarantors and shall in no way affect the obligations of the
Guarantors hereunder to make payments in full to the Administrative Agent and
the Secured Parties as specified herein.

     SECTION 16. Limitation of Liability. Each Guarantor hereby confirms that it
is the intention of such Guarantor that the guarantee by such Guarantor pursuant
to this Guarantee Agreement not constitute a fraudulent transfer or conveyance
for purposes of Title 11 of the United States Code, the Uniform Fraudulent
Conveyance Act, the Uniform Fraudulent Transfer Act or any similar Federal or
state law. To effectuate the foregoing intention, such Guarantor hereby
irrevocably agrees that the obligations of such Guarantor under this Guarantee
Agreement shall be limited to the maximum amount as will result in the
obligations of such Guarantor under this Guarantee Agreement not constituting
such a fraudulent transfer or conveyance. In the event that any Guarantor's
liability hereunder is limited pursuant to this Section 15 to an amount that is
less than the total amount of the Guaranteed Obligations, then it is understood
and agreed that the portion of the Guaranteed Obligations for which such
Guarantor is liable hereunder shall be the last portion of the Guaranteed
Obligations to be repaid.

     SECTION 17. Supplemental Agreement. Upon execution and delivery by the
Administrative Agent and a Subsidiary of a Supplemental Agreement substantially
in the form of Exhibit V to the Credit Agreement, such Subsidiary shall become a
Guarantor hereunder with the same force and effect as if originally named as a
Guarantor herein. The execution and delivery of any such instrument shall not
require the consent of any other Guarantor hereunder. The rights and obligations
of each Guarantor hereunder shall remain in full force and effect
notwithstanding the addition of any new Guarantor as a party to this Guarantee
Agreement.

     SECTION 18. Counterparts. This Guarantee Agreement may be executed in two
or more counterparts, each of which shall constitute an original, but all of
which, when taken together, shall constitute but one instrument. This Guarantee
Agreement shall be effective with respect to any Guarantor when a counterpart
hereof (or of the applicable Supplemental Agreement) which bears the signature
of such Guarantor shall have been delivered to the Administrative Agent.

     SECTION 19. Savings Clause. In the event any one or more of the provisions
contained in this Guarantee Agreement should be held invalid, illegal or
unenforceable in any respect with respect to any Guarantor, no party hereto
shall be required to comply with such provision with respect to such Guarantor
for so long as such provision is held to be invalid, illegal or unenforceable,
and the validity, legality and enforceability of the remaining provisions
contained herein, and of such invalid, illegal or unenforceable provision with
respect to any other Guarantor, shall not in any way be affected or impaired.
The parties shall endeavor in good-faith negotiations to replace any invalid,
illegal or unenforceable provisions with valid provisions, the economic effect
of which comes as close as possible to that of the invalid, illegal or
unenforceable provisions.

     SECTION 20. Governing Law. THIS GUARANTEE SHALL BE GOVERNED BY AND
INTERPRETED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK OTHER THAN ANY
SUCH REQUIREMENT OF LAWS THAT WOULD APPLY THE LAWS OF ANOTHER JURISDICTION,
EXCEPT TO THE EXTENT THAT THE LAWS OF ANOTHER JURISDICTION ARE MANDATORILY
APPLICABLE. ANY DISPUTE ARISING OUT OF, CONNECTED WITH, RELATED TO, OR
INCIDENTAL TO THE RELATIONSHIP ESTABLISHED BETWEEN THE GUARANTORS AND EACH
SECURED PARTY IN CONNECTION WITH THIS GUARANTEE AND THE OTHER FINANCING
DOCUMENTS, AND WHETHER ARISING IN CONTRACT, TORT, EQUITY OR OTHERWISE, SHALL BE
RESOLVED IN ACCORDANCE WITH THE INTERNAL LAWS (AS OPPOSED TO THE CONFLICTS OF
LAWS PROVISIONS) AND DECISIONS OF THE STATE OF NEW YORK.

     SECTION 21. Jurisdiction; Consent to Service of Process. (a) Each Guarantor
hereby irrevocably and unconditionally submits, for itself and its property, to
the nonexclusive jurisdiction of any New York State court or Federal court of
the United States of America sitting in the Southern District of New York, and
any appellate court from any thereof, in any action or proceeding arising out of
or relating to this Guarantee Agreement or the other Financing Documents, or for
recognition or enforcement of any judgment, and hereby irrevocably and
unconditionally agrees that all claims in respect of any such action or
proceeding may be heard and determined in such New York State or, to the extent
permitted by law, in such Federal court. Each of the parties hereto agrees that
a final judgment in any such action or proceeding shall be conclusive and may be
enforced in other jurisdictions by suit on the judgment or in any other manner
provided by law. Nothing in this Guarantee Agreement shall affect any right that
the Administrative Agent or any other Secured Party may otherwise have to bring
any action or proceeding relating to this Guarantee Agreement or the other
Financing Documents against any Guarantor or its properties in the courts of any
jurisdiction.

     (b) Each Guarantor hereby irrevocably and unconditionally waives, to the
fullest extent it may legally and effectively do so, any objection which it may
now or hereafter have to the laying of venue of any suit, action or proceeding
arising out of or relating to this Guarantee Agreement or the other Financing
Documents in any New York State court or Federal court of the United States of
America sitting in the Southern District of New York. Each of the parties hereto
hereby irrevocably waives, to the fullest extent permitted by law, the defense
of an inconvenient forum to the maintenance of such action or proceeding in any
such court.

     (c) Each party to this Guarantee Agreement irrevocably consents to service
of process in the manner provided for notices in Section 9. Nothing in this
Guarantee Agreement will affect the right of any party to this Guarantee
Agreement to serve process in any other manner permitted by law.

     (d) To the fullest extent permitted under applicable law, each Guarantor
hereby irrevocably and unconditionally waives all rights to trial by jury in any
action, proceeding or counterclaim arising out of or related to this Agreement
and the other Financing Documents or any of the transactions contemplated hereby
or thereby.

     SECTION 22. Subordination by Guarantors. Each Guarantor hereby subordinates
in right of payment all indebtedness of the Borrower or any other Guarantor
owing to it, whether originally contracted with such Guarantor or acquired by
such Guarantor by assignment, transfer or otherwise, whether now owed or
hereafter arising, whether for principal, interest, fees, expenses or otherwise,
together with all renewals, extensions, increases or rearrangements thereof, to
the prior indefeasible payment in full in cash of the Guaranteed Obligations,
whether now owed or hereafter arising, whether for principal, interest
(including interest accruing after the filing of a petition initiating any
proceeding referred to in Section 7.07 of the Credit Agreement), fees, expenses
or otherwise, together with all renewals, extensions, increases or
rearrangements thereof.

     SECTION 23. Survival of Agreement. All covenants, agreements,
representations and warranties made by each Guarantor herein shall be considered
to have been relied upon by the Administrative Agent and the other Secured
Parties and shall survive the making by the Lenders of the Loans and the
execution and delivery to the Lenders of the Notes evidencing such Loans,
regardless of any investigation made by the Lenders or the Agents or on their
behalf, and shall continue in full force and effect until the Guaranteed
Obligations and any other amounts payable under this Guarantee Agreement or any
other Financing Document have been indefeasibly paid in full in cash and the
Commitments have been terminated.

     SECTION 24. Entire Agreement. This Guarantee Agreement and the other
Financing Documents constitute the entire contract between the parties relative
to the subject matter hereof. Any agreement previously entered into among the
parties with respect to the subject matter hereof is superseded by this
Guarantee Agreement and the other Financing Documents. Nothing in this Guarantee
Agreement, expressed or implied, is intended to confer upon any party, other
than the parties hereto and the other Secured Parties, any rights, remedies,
obligations or liabilities under or by reason of this Guarantee Agreement.

successors and assignees as the case may be, for any monies paid by it with
interest thereon at the Default Rate from the date the same shall have been paid
by the Administrative Agent and/or its agents, representatives, successors and
assigns until actually paid

                                       10

RIGHTS; INSTRUMENTS.

              4.01      Additional Representations and Warranties. As of the
time when each Receivable and General Intangible arises, the Grantor shall be
deemed to have represented and warranted, to the knowledge of the Grantor and
unless otherwise promptly disclosed by the Grantor in writing to the
Administrative Agent upon the Grantor obtaining actual knowledge thereof, that
such Receivable or General Intangible, as the case may be, and all records,
papers and documents relating thereto (if any) are genuine and in all respects
what they purport to be, and that all records, papers and documents (if any)
relating thereto (i) will represent the genuine, legal, valid and binding
obligation of the account debtor evidencing indebtedness unpaid and owed by the
respective account debtor arising out of the performance of labor or services or
the sale or lease and delivery of electricity or capacity, or any other
merchandise listed therein, or both, and (ii) are in compliance and will conform
with all Requirements of Law.

              4.02      Maintenance of Records. The Grantor will keep and
maintain at its own cost and expense records consistent with GAAP of the
Assigned Agreements and the Receivables, including, but not limited to, the
originals of all documentation (including each Assigned Agreement) with respect
thereto, records of all payments received, all credits granted thereon (but
subject to customary record retention policies) and all other dealings
therewith. The Grantor will make the same available to the Administrative Agent

              4.03      Payments Under Assigned Agreements, Receivables and
General Intangibles. (a) Non-Payment to the Administrative Agent. If the Grantor
shall receive payment directly from any party to an Assigned Agreement
(including any letter of credit issued for the benefit of the Grantor in
accordance with the terms thereof) or from any account debtor or other obligor
under any Receivable, General Intangible or any other payments under such
Assigned Agreements, Receivables and General Intangibles, the Grantor shall
receive such payments in a constructive trust for the benefit of the Lenders,
shall segregate such payments from such party's other funds, and shall forthwith
transmit and deliver such payments to the Administrative Agent in the same form
as so received (with any necessary endorsement).

              (b)       Application of Funds. All amounts received by the
Administrative Agent pursuant to this Section 4.03 or Section 4.04 shall be
deposited into the Revenue Account and applied as set forth in the Deposit
Account Agreement.

              4.04      Direction to Account Debtors; Contracting Parties; etc.
The Grantor agrees that the Administrative Agent may, upon reasonable notice to
Grantor of its failure to do so directly notify the obligors with respect to any
Receivables, General Intangibles and/or under any Assigned Agreements to make
payments with respect thereto as provided in Sections 2.01(c) (ii) and 4.03.
Upon the occurrence and during the continuance of any Event of Default, the

                                       14
<PAGE>   362

Administrative Agent may apply, without notice to or assent by the Grantor, any
or all amounts then in, or thereafter deposited in, the Accounts in the manner
provided in the Deposit Account Agreement. The reasonable costs and expenses
(including reasonable attorneys' fees) of collection, whether incurred by the
Grantor or the Administrative Agent, shall be borne by the Grantor.

              4.05      Modification of Terms, etc. Except as otherwise provided
in the Credit Agreement or as permitted in Section 4.06 hereof, (a) the Grantor
shall not rescind or cancel any Indebtedness in any fiscal year in an amount, in
the aggregate, in excess of $100,000 evidenced by any Receivables, General
Intangibles or Assigned Agreements, or modify in any manner adverse to the
Grantor or the Secured Parties any material term thereof, or make any adjustment
adverse to the Grantor or the Secured Parties with respect thereto, or grant any
extension for performance of the same, or compromise or settle any dispute,
claim, suit or legal proceeding relating thereto, or sell any Receivable,
General Intangible or Assigned Agreements, or interest therein, without the
prior written consent of the Administrative Agent, which consent the
Administrative Agent will not unreasonably withhold, delay or condition, and (b)
the Grantor will duly fulfill all material obligations on its part to be
fulfilled under or in connection with the Receivables, the General Intangibles
and the Assigned Agreements and will do nothing to impair the security interests
of the Administrative Agent (including, without limitation, the creation,
attachment and priority thereof) in the Receivables, the General Intangibles or
the Assigned Agreements.

              4.06      Collection. The Grantor shall endeavor to cause to be
collected from the account debtor named in the Grantor's Receivables and General
Intangibles or obligor under any Assigned Agreements, and paid by such account
debtor directly to the Revenue Account, as and when due (including, without
limitation, amounts which are delinquent, such amounts to be collected in
accordance with generally accepted lawful collection procedures) any and all
amounts owing under or on account of such Receivable, General Intangible or
Assigned Agreements, and apply forthwith upon receipt thereof all such amounts
as are so collected to the outstanding balance of such Receivable, General
Intangible or under such Assigned Agreements, except that, unless an Event of
Default shall have occurred and be continuing (and shall not have been waived by
an appropriate vote or other action by the Required Lenders), the Grantor may
allow in the ordinary course of business as adjustments to amounts owing under
the Grantor's Receivables, General Intangibles and Assigned Agreements an
extension or renewal of the time or times of payment, or settlement for less
than the total unpaid balance, which the Grantor finds appropriate to enhance
collectibility in accordance with sound business judgment. The reasonable costs
and expenses (including, without limitation, reasonable attorneys fees) of
collection, whether incurred by the Grantor or the Administrative Agent, shall
be borne by the Grantor.

              SECTION 5.  SPECIAL PROVISIONS CONCERNING PATENTS, COPYRIGHTS AND
TRADEMARKS.

              5.01      Infringements. Promptly upon obtaining actual knowledge
thereof, the Grantor shall notify the Administrative Agent and the Lenders in
writing of all pertinent details

                                       15
<PAGE>   363

available to it, with respect to any infringement or other violation of the
Grantor's rights in, or any claim of any such infringement of, any, Patent,
Copyright or Trademark, whether or not such right is presently held by the
Grantor or third party. As to each such instance, absent the Required Lenders'
authorization to proceed otherwise, which authorization shall not be
unreasonably withheld, delayed or conditioned, and to the extent permitted by
applicable Requirements of Law, the Grantor shall use commercially reasonable
efforts to pursue a remedy.

              5.02      Other Patents, Copyrights and Trademarks. If the
Grantor hereafter acquires rights in any Patent, Copyright or Trademark, the
Grantor shall deliver to the Administrative Agent and the Lenders within 30
days, a copy of such Patent, Copyright or Trademark and a first priority
perfected security interest therein or a collateral assignment thereof, as
appropriate.

              5.03      Remedies. If an Event of Default shall occur and be
continuing (and shall not have been waived by an appropriate vote or other
action by the Lenders), the Administrative Agent, acting pursuant to and in
accordance with the terms of the Deposit Account Agreement, the other Financing
Documents and applicable Requirements of Law may (a) declare the entire right,
title, and interest of the Grantor in any Patents, Copyrights and Trademarks
vested in the Administrative Agent, in which event such right, title, and
interest immediately shall vest in the Administrative Agent; and (b) take and
practice or use or sell any or all of such Patents, Copyrights or Trademarks, or
take and use or sell the Grantor's rights in such Patents, Copyrights or
Trademarks, along with the goodwill and all other elements of the Grantor's
ongoing business symbolized by such assets and secured under this Agreement, and
the right to carry on the business of the Grantor in connection with which such
assets have been used. The Grantor shall execute any other and further documents
which the Administrative Agent may request further to confirm the foregoing and
to transfer to the Administrative Agent ownership of the Grantor's rights to
such Trademarks, Patents and/or Copyrights.

              SECTION 6.  PROVISIONS CONCERNING ALL ASSIGNMENT REVENUES AND
ASSIGNMENT COLLATERAL; INSURANCE.

              6.01      Protection of the Administrative Agent's Interests. The
Grantor will do nothing to impair the rights of the Administrative Agent or the
Lenders in the Assignment Revenues and the Assignment Collateral, provided,
however, that nothing herein shall prevent the Grantor, prior to the exercise by
the Administrative Agent of any such rights, from undertaking the Grantor's
operations in the ordinary course of business in accordance with the Assigned
Agreements. The Grantor assumes all liability and responsibility in connection
with the Assignment Revenues and the Assignment Collateral and the liability of
the Grantor with respect to the Secured Obligations shall in no way be affected
or diminished by reason of the fact that such Assignment Revenues and Assignment
Collateral may be lost, destroyed, stolen, damaged or for any reason whatsoever
unavailable to the Grantor.

              6.02      Further Actions. The Grantor will, at its own expense,
make, execute, endorse, acknowledge, file and/or deliver to the Administrative
Agent and the Lenders from time to time such lists, descriptions and
designations of the Assignment Revenues and the Assignment

                                       16
<PAGE>   364

Collateral, warehouse receipts, receipts in the nature of warehouse receipts,
bills of lading, documents of title, vouchers, invoices, schedules, confirmatory
assignments, conveyances, financing statements, transfer endorsements, powers of
attorney, certificates, reports and other assurances or instruments and take
such further steps relating to the Assignment Revenues and the Assignment
Collateral and other property or rights covered by the interests hereby granted,
which is necessary to perfect, preserve or protect its ownership and security
interests in the Assignment Revenues and the Assignment Collateral or is
otherwise reasonably requested by the Administrative Agent; provided, that the
foregoing shall not require the Grantor to obtain any Additional Contract
Consent except as expressly required by Section 5.24 of the Credit Agreement.

              6.03      Financing Statements. The Grantor agrees to assign and
deliver to the Administrative Agent, on behalf of the Lenders, such financing
statements (or similar statement or instrument of registration under the law of
any jurisdiction), in form reasonably acceptable to the Administrative Agent as
it may from time to time reasonably request or as are necessary or desirable in
their reasonable opinion to establish and maintain the security interests
contemplated hereunder as valid, enforceable, first priority security interests
as provided herein and the other rights and security contemplated herein, all in
accordance with the Uniform Commercial Code as enacted in any and all relevant
jurisdictions or any other Requirement of Law. The Grantor will pay any
applicable filing fees and related expenses. The Grantor authorizes the
Administrative Agent to file any such financing statements without the signature
of the Grantor to the extent permitted under applicable Requirements of Law.

              SECTION 7.  REMEDIES UPON OCCURRENCE OF EVENT OF DEFAULT.

              7.01      Remedies; Obtaining the Assignment Collateral Upon
Default. The Grantor agrees that, if any Event of Default shall have occurred
and be continuing (and shall not have been waived by an appropriate vote or
other action by the Required Lenders), then and in every such case, subject to
the terms and provisions of the Credit Agreement and any Requirement of Law then
in effect, the Administrative Agent, in addition to any rights now or hereafter
existing under any Requirement of Law, shall have all rights as a secured
creditor under the Uniform Commercial Code or any other Requirement of Law in
all relevant jurisdictions and may, acting pursuant to and in accordance with
the terms of the Credit Agreement:

              (a)       personally, or by agents or attorneys, immediately
       retake possession of the Assignment Collateral or any part thereof, from
       the Grantor or any other Person who then has possession of any part
       thereof with or without notice or process of law, and for that purpose
       may enter upon the Grantor's premises where any of the Assignment
       Collateral is located and remove the same and use in connection with such
       removal any and all services, supplies, aids and other facilities of the
       Grantor; and

              (b)       instruct the obligor or obligors on any agreement,
       instrument or other obligation (including, without limitation, any other
       Assigned Agreement, the General Intangibles and the Receivables)
       constituting the Assignment Revenues and Assignment Collateral to make
       any payment required by the terms of such instrument or agreement
       directly to the Administrative Agent for deposit in the Revenue Account
       (or any other

                                       17
<PAGE>   365

       account required or contemplated by the Deposit Account Agreement) and
       application pursuant to the Deposit Account Agreement; and

              (c)       apply all monies, securities and instruments in the
       Revenue Account, and each other Account, in accordance with the Deposit
       Account Agreement; and

              (d)       sell, assign or otherwise liquidate, or direct the
       Grantor to sell, assign or otherwise liquidate, any or all of the
       Assignment Collateral or any part thereof, and take possession of the
       proceeds of any such sale or liquidation for deposit in the Revenue
       Account (or any other account required or contemplated by the Deposit
       Account Agreement) and application pursuant to the Deposit Account
       Agreement; and

              (e)       take possession of the Assignment Collateral or any
       part thereof, by directing the Grantor in writing to deliver the same to
       the Administrative Agent at any place or places designated by the
       Administrative Agent, in which event the Grantor shall at its own
       expense:

                        (i)      forthwith cause the same to be moved to the
              place or places so designated by the Administrative Agent and
              there delivered to the Administrative Agent,

                        (ii)     store and keep any Assignment Collateral so
              delivered to the Administrative Agent (to the extent not
              physically delivered to the Administrative Agent) at such place or
              places pending further action by the Administrative Agent as
              provided in Section 7.02, and

                        (iii)    while such Assignment Collateral shall be so
              stored and kept, provide such guards and maintenance services as
              shall be necessary to protect the same and to preserve and
              maintain them in good condition;

       it being understood that the Grantor's obligation to so deliver the
       Assignment Collateral is of the essence of this Agreement and that,
       accordingly, upon application to a court of equity having jurisdiction,
       the Administrative Agent shall be entitled to a decree requiring specific
       performance by the Grantor of such obligation.

              7.02      Remedies, Disposition of the Assignment Collateral. Any
Assignment Collateral repossessed by the Administrative Agent under or pursuant
to Section 7.01, and any other Assignment Collateral whether or not so
repossessed by the Administrative Agent, may be sold, assigned, leased or
otherwise disposed of under one or more contracts or as an entirety, and without
the necessity of gathering at the place of sale the property to be sold, and in
general in such manner, at such time or times, at such place or places and on
such terms as the Administrative Agent, acting in good faith, may, upon written
direction in compliance with any Requirement of Law, determine to be
commercially reasonable. Subject to the foregoing, any of the Assignment
Collateral may be sold, leased or otherwise disposed of, in the condition in
which the same existed when taken by the Administrative Agent or after any
overhaul or repair which the Administrative Agent, acting in good faith, shall
determine to be commercially

                                       18
<PAGE>   366

reasonable. Any such disposition which shall be a private sale or other private
proceeding permitted by such requirements shall be made upon not less than 10
days' written notice to the Borrower specifying the time at which such
disposition is to be made and the intended sale price or other consideration
therefor, and shall be subject, for the 10 days after the giving of such notice,
to the right of the Grantor or any nominee of the Grantor to acquire the
Assignment Collateral involved at a price or for such other consideration at
least equal to the intended sale price or other consideration so specified. To
the extent permitted by Requirements of Law, the Administrative Agent on behalf
of the Lenders may bid for and become the purchaser of the Assignment Collateral
or any item thereof, offered for sale in accordance with this Section 7.02. If,
under mandatory requirements of any Requirement of Law, the Administrative Agent
shall be required to make disposition of the Assignment Collateral within a
period of time which does not permit the giving of notice to the Grantor as
hereinabove specified, the Administrative Agent need give the Grantor only such
notice of disposition as shall be reasonably practicable in view of such
mandatory requirements of any Requirement of Law.

              The Grantor hereby irrevocably appoints the Administrative Agent
as its attorney-in-fact, so that the Administrative Agent, or any Person
empowered by the Administrative Agent, shall be authorized to sell, assign,
lease or otherwise dispose of the Assignment Collateral or any part thereof
pursuant to the provisions of the preceding paragraph, and, in general, to do or
cause to be done all such acts and things which are otherwise required to be
done by the Grantor under this Agreement.

              7.03      Waiver of Claims. Except as otherwise provided in this
Agreement or in any other Financing Document, THE GRANTOR HEREBY WAIVES, TO THE
EXTENT PERMITTED BY APPLICABLE LAW, NOTICE AND JUDICIAL HEARING IN CONNECTION
WITH THE ADMINISTRATIVE AGENT TAKING POSSESSION OR THE ADMINISTRATIVE AGENT'S
DISPOSITION OF ANY OF THE ASSIGNMENT COLLATERAL, IN EACH CASE AS PERMITTED BY
APPLICABLE REQUIREMENTS OF LAW, INCLUDING, WITHOUT LIMITATION, ANY AND ALL PRIOR
NOTICE AND HEARING FOR ANY PREJUDGMENT REMEDY OR REMEDIES AND ANY SUCH RIGHT
WHICH THE GRANTOR WOULD OTHERWISE HAVE UNDER THE CONSTITUTION OR ANY STATUTE OF
THE UNITED STATES OR ANY POLITICAL SUBDIVISION OF ANY SUCH JURISDICTION, and the
Grantor hereby further waives, to the extent permitted by Requirements of Law:

              (i)       all damages occasioned by such taking of possession
       except any damages which are the direct result of the gross negligence or
       willful misconduct of the Administrative Agent, any Lender, or any Person
       acting on its behalf or instruction;

              (ii)      all other requirements as to the time, place and terms
       of sale or other requirements with respect to the enforcement of the
       Administrative Agent's rights hereunder; and

              (iii)     all rights of redemption, appraisement, valuation, stay,
       extension or moratorium now or hereafter in force under any Requirements
       of Law in order to prevent or delay the enforcement of this Agreement
       (including, without limitation, any right to

                                       19
<PAGE>   367

       claim that such enforcement should be stayed pending the outcome of any
       other action or proceeding (including any arbitration proceeding)) or the
       absolute sale of the Assignment Collateral or any portion thereof, and
       the Grantor, for itself and all who may claim under it, insofar as it or
       they now or hereafter lawfully may, hereby waives the benefit of all such
       Requirements of Law.

To the extent permitted under Requirements of Law, any sale of, or the grant of
options to purchase, or any other realization upon, any Assignment Collateral
shall operate to divest all right, title, interest, claim and demand, either at
law or in equity, of the Grantor therein and thereto, and shall be a perpetual
bar both at law and in equity against the Grantor and against any and all
Persons claiming or attempting to claim the Assignment Collateral so sold,
optioned or realized upon, or any part thereof, from, through and under the
Grantor.

              7.04      Application of Proceeds. The Proceeds of any Assignment
Collateral obtained or disposed of pursuant to this Agreement, including
Sections 7.01 and 7.02 shall be applied in accordance with the Deposit Account
Agreement.

For the avoidance of doubt, it is understood that the Grantor shall remain
liable to the extent of any deficiency between the amount of the Proceeds of the
Assignment Collateral and the aggregate amount of the Secured Obligations.

              7.05      Remedies Cumulative. No failure or delay on the part of
the Administrative Agent or any Lender in exercising any right, power or
privilege hereunder or under any other Financing Document and no course of
dealing between the Grantor and the Administrative Agent or any Lender shall
operate as a waiver thereof; nor shall any single or partial exercise of any
right, power or privilege hereunder or under any other Financing Document
preclude any other or further exercise thereof or the exercise of any other
right, power or privilege hereunder or thereunder. The rights, powers and
remedies herein or in any other Financing Document expressly provided are
cumulative and not exclusive of any rights, powers or remedies which the
Administrative Agent or any Lender would otherwise have. No notice to or demand
on the Grantor in any case shall entitle the Grantor to any other or further
notice or demand in similar or other circumstances or constitute a waiver of the
rights of the Administrative Agent or any Lender to any other or further action
in any circumstances without notice or demand.

                                       20
<PAGE>   368

              7.06      Discontinuance of Proceedings. In case the
Administrative Agent shall have instituted any proceeding to enforce any right,
power or remedy under this Agreement by foreclosure, sale, entry or otherwise,
and such proceeding shall have been discontinued or abandoned for any reason or
shall have been determined adversely to the Administrative Agent, then and in
every such case the Grantor, the Administrative Agent and each holder of any of
the Obligations shall be restored to their former positions and rights hereunder
with respect to the Assignment Collateral subject to the security interest
created under this Agreement, and all rights, remedies and powers of the
Administrative Agent shall continue as if no such proceeding had been
instituted.

              7.07      Grant of License or Sub-License to Use Patent,
Trademark, Copyright and License Collateral. For the purpose of enabling the
Administrative Agent to exercise rights and remedies under this Article VII at
such time as the Administrative Agent shall be lawfully entitled to exercise
such rights and remedies, the Grantor hereby grants to Administrative Agent an
irrevocable, non-exclusive license (exercisable without payment of royalty or
other compensation to the Grantor) to use, license or sub-license any Patent,
Trademark, Copyright or License (to the extent the Grantor has authority to
sub-license any such License) now owned or licensed or hereafter acquired or
licensed by the Grantor, and wherever the same may be located, and including in
such license reasonable access to all media in which any of the licensed items
may be recorded or stored and to all computer software and programs used for the
compilation or printout thereof. The use of such license or sub-license by the
Administrative Agent shall be exercised, at the option of the Administrative
Agent, only upon the occurrence and during the continuation of an Event of
Default; provided that any license, sub-license or other transaction entered
into by the Administrative Agent in accordance herewith shall be binding upon
the Grantor notwithstanding any subsequent cure of an Event of Default. The
Administrative Agent agrees to apply the net Proceeds received from any such
license as provided in Section 7.04 hereof.

              SECTION 8. INDEMNITY; EXPENSES.

       (a)    Grantor agrees to indemnify and hold harmless the Administrative
Agent and each Secured Party from and against any and all claims, losses and
liabilities arising out of or resulting from the Collateral or Grantor's pledge
and assignment under this Agreement (including, without limitation, enforcement
against Grantor of this Agreement), except claims, losses or liabilities
resulting from the gross negligence or willful misconduct of any Secured Party
or any other Person designated by any Secured Party to act on its behalf
pursuant to this Agreement.

       (b)    Grantor will upon demand pay to the Administrative Agent or any
Secured Party the amount of any and all reasonable expenses, including the
reasonable fees and expenses of its counsel and of any experts and agents, which
the Administrative Agent or any Secured Party may incur in connection with (i)
the administration of this Agreement, (ii) the sale of, collection from, or
other realization upon, any of the Collateral of the Grantor, (iii) the exercise
or enforcement (whether through negotiations, legal proceedings or otherwise) of

       the Mortgaged Property or affecting a material portion of the Mortgaged
       Property (collectively, the "Material Agreements"), other than the
       Project Contracts relating to the Mortgaged Property. Each Material
       Agreement is in full force and effect with respect to the Mortgagor and,
       to the Mortgagor's knowledge, each other party thereto, and, except as
       set forth on Exhibit C attached hereto, the Mortgagor has not given, nor
       has it received, any notice of default with respect to any material
       obligation under any Material Agreement. The Mortgagor's interests under
       each Material Agreement is not subject to any Lien, other than this
       Mortgage, the Permitted Encumbrances and other Permitted Liens.

       authority to encumber or grant a security interest in the Mortgaged
       Property. The Mortgagor will forever warrant and defend its title to the
       Mortgaged Property, the rights of the Mortgagee therein under this
       Mortgage and the validity and priority of the lien of this Mortgage
       thereon against the claims of all persons and parties except those having
       rights under the Permitted Encumbrances or other Permitted Liens to the
       extent of those rights.

              (d)    This Mortgage, when duly recorded in the appropriate public
       records and when financing statements are duly filed in the appropriate
       public records, will create a valid, perfected and enforceable lien upon
       and security interest in all the Mortgaged Property.

       Each and every term and provision of the Credit Agreement, including,
       without limitation, the rights, remedies, obligations, covenants,
       conditions, agreements, indemnities, representations and warranties of

       Mortgagor in respect of loan disbursements made by the Lenders under the
       Acquisition Loan Notes, and all other Obligations from time to time owing
       to the Lenders under the Financing Documents (other than with respect to
       Working Capital Loans).

              (b)    If any remedy or right of the Mortgagee pursuant hereto is
       acted upon by the Mortgagee or if any actions or proceedings (including
       any bankruptcy, insolvency or reorganization proceedings) are commenced
       in which the Mortgagee is made a party and is obliged to defend or uphold
       or enforce this Mortgage or the rights of the Mortgagee hereunder or the
       terms of any Lease, or if a condemnation proceeding is instituted
       affecting the Mortgaged Property, the Mortgagor will pay all sums,
       including reasonable attorneys' fees and disbursements, actually incurred
       (not as imposed by statute) by the Mortgagee related to the exercise of
       any remedy or right of the Mortgagee pursuant hereto or for the expense
       of any such action or proceeding together with all other costs (not as
       imposed by statute), disbursements and allowances, interest thereon from
       the date of demand for payment thereof at the rate specified in Section
       2.06(c) of the Credit Agreement (the "Default Interest Rate"), and such
       sums and the interest thereon shall, to the extent permissible by
       Requirements of Law, be a lien on the Mortgaged Property prior to any
       right, title to, interest in or claim upon the Mortgaged Property
       attaching or accruing subsequent to the recording of this Mortgage and,
       subject to the limitations set forth in Section 1.03, shall be secured by
       this Mortgage to the extent permitted by applicable Requirements of Law.

              (c)    Any payment of amounts due under this Mortgage not made on
       or before the due date for such payments shall accrue interest daily
       without notice from the due date until paid at the Default Interest Rate,
       and such interest at the Default Interest Rate shall be immediately due
       upon demand by the Mortgagee.

       SECTION 1.06       Payment of Taxes, Liens and Charges.

              (a)    The Mortgagor will pay and discharge from time to time
       prior to the time when the same shall become delinquent, and before any
       interest or penalty accrues thereon or attaches thereto, all taxes of
       every kind and nature, all general and special assessments, levies,
       permits, inspection and license fees, all water and sewer rents, all
       vault charges, and all other public charges, and all service charges,
       common area charges, private maintenance charges, mechanics liens,
       utility charges and all other private charges, whether of a like or
       different nature, imposed upon or assessed against the Mortgaged Property
       or any part

                                       9
<PAGE>   393

       thereof or upon the Rents from the Mortgaged Property or arising in
       respect of the occupancy, use or possession thereof. Notwithstanding the
       foregoing, the Mortgagor shall have the right to contest in good faith
       the validity or amount of any such tax, assessment, charge or levy by
       proper proceedings, and may permit the taxes, assessments, charges or
       levies so contested to remain unpaid during the period of such contest
       if: (a) the Mortgagor diligently prosecutes such contest in good faith
       and by appropriate proceedings and for which Acceptable Reserves have
       been established; (b) during the period of such contest, the enforcement
       of any contested item is effectively stayed; and (c) the failure to pay
       or comply with the contested item could not reasonably be expected to
       result in a Material Adverse Effect taking into account the existence of
       such Acceptable Reserves.

              (b)    In the event of the passage of any state, Federal,
       municipal or other governmental law, order, rule or regulation subsequent
       to the date hereof (i) deducting from the value of real property for the
       purpose of taxation any lien or encumbrance thereon or in any manner
       changing or modifying the laws now in force governing the taxation of
       this Mortgage or debts secured by mortgages or deeds of trust (other than
       laws governing income, franchise and similar taxes generally) or the
       manner of collecting taxes thereon and (ii) imposing a tax to be paid by
       the Mortgagee, either directly or indirectly, on this Mortgage or any of
       the Financing Documents or to require an amount of taxes to be withheld
       or deducted therefrom, upon obtaining actual knowledge thereof, the
       Mortgagor will promptly notify the Mortgagee of such event. In such event
       the Mortgagor shall (i) agree to enter into such further instruments as
       may be reasonably necessary or desirable to obligate the Mortgagor to
       make any applicable additional payments and (ii) the Mortgagor shall make
       all such additional payments, except as such law, order, rule, regulation
       or payment may be contested by the Mortgagor in good faith and by
       appropriate proceedings and pursuant to which Acceptable Reserves have
       been established.

       SECTION 1.07       Payment of Closing Costs. The Mortgagor shall pay all
reasonable costs in connection with, relating to or arising out of the
preparation, execution and recording of this Mortgage, including title company
premiums and charges, inspection costs, survey costs, recording fees and taxes
(including without limitation all New York Mortgage Recording Taxes),
attorneys', engineers', appraisers' and consultants' fees and disbursements and
all other similar expenses of every kind.

       SECTION 1.08       Alterations and Waste; Plans; Use.

              (a)    The Mortgagor will (i) operate and maintain the Mortgaged
       Property in accordance with Prudent Industry Practice and the relevant
       permits (in all material respects and subject to contest rights set forth
       in the Credit Agreement) and in accordance with the terms of any
       insurance policy or policies in effect at any time with respect to the
       Mortgaged Property or any part thereof, (ii) subject to Section 6.11 of
       the Credit Agreement, keep the Mortgaged Property in good working order
       and condition (except to the extent that any portion of such

                                       10
<PAGE>   394

       Mortgaged Property is no longer required for the business of the
       Mortgagor), ordinary wear and tear excepted, and (iii) maintain books,
       records, plans and specifications relating thereto, in accordance with
       Prudent Industry Practice.

              (b)    The Mortgagor shall cause the Premises and the Improvements
       to be used in material compliance with all applicable Requirements of Law
       and applicable Governmental Approvals, except when any such Requirement
       of Law or Governmental Approval is being contested by the Mortgagor in
       good faith and by appropriate proceedings and pursuant to which contest
       Acceptable Reserves have been established. Upon obtaining actual
       knowledge thereof, the Mortgagor shall promptly notify the Mortgagee of
       any proposed zoning reclassification, variance, conditional or special
       use permit, subdivision plat or annexation adversely affecting the Land.
       The Mortgagor shall at all times comply with its material obligations
       under all recorded restrictions, conditions, easements and covenants
       ("Restrictive Covenants") encumbering the Land and shall duly enforce its
       rights under all Restrictive Covenants encumbering other property for the
       benefit of the Land and/or the Improvements. If the Mortgagor receives
       any notice (whether oral or written) that any Restrictive Covenant has
       been violated, which violation could be reasonably likely to materially
       and adversely affect title to the Land or the Grantor's existing or
       intended use of the Land or the Improvements or result in material liens,
       fines, penalties or encumbrances being imposed on the Land or
       Improvements, the Mortgagor shall promptly notify the Mortgagee and take
       such steps as the Mortgagee may reasonably require to correct such
       violation.

       SECTION 1.09       Insurance. The Mortgagor will keep the Mortgaged
Property insured against such risks, and in the manner, required by Section 5.06
of the Credit Agreement. Payment for any loss under any policy of insurance
covering loss or damage to the Mortgaged Property shall be made and applied in
accordance with the terms of the Credit Agreement and the Deposit Account
Agreement.

       SECTION 1.10       Casualty; Restoration of Casualty Damage. The
Mortgagor shall give the Mortgagee prompt written notice of any fire or other
material casualty to all or any portion of the Mortgaged Property (a
"Casualty"). Proceeds of any such casualty shall be held and applied as set
forth in, and any restoration, repair or rebuilding of the Mortgaged Property
shall be performed by the Mortgagor as set forth in the Credit Agreement and the
Deposit Account Agreement. The provisions of subsection 4 of Section 254 of the
Real Property Law of New York covering the insurance of buildings against loss
by fire that are inconsistent with the provisions of this Mortgage shall not
apply to the terms of this Mortgage. Nothing contained herein, except for the
immediately preceding sentence, shall be construed as depriving the Mortgagee of
any right or advantage available under Section 254 of the Real Property Law of
the State of New York, and all covenants herein that differ therefrom shall be
construed as conferring additional and not substitute rights and advantages.

                                       11
<PAGE>   395

       SECTION 1.11       Condemnation/Eminent Domain. The Mortgagor shall
notify the Mortgagee promptly upon obtaining actual knowledge of any pending or
threatened condemnation or taking of all or any portion of the Mortgaged
Property (a "Condemnation"). All awards and proceeds of any such condemnation or
talking shall be applied in accordance with the terms of the Credit Agreement
and the Deposit Account Agreement.

       SECTION 1.12       Assignment of Leases and Rents.

              (a)    The Mortgagor hereby irrevocably and absolutely grants,
       transfers and assigns to the Mortgagee all of its right, title and
       interest in and to all Leases, together with any and all extensions and
       renewals thereof for purposes of securing and discharging the performance
       by Orion Power and the Mortgagor of the Obligations. The Mortgagor has
       not assigned or executed any assignment of, and will not assign or
       execute any assignment of, any Lease or its respective Rents to anyone
       other than to the Mortgagee.

              (b)    This Mortgage is intended to be, and shall operate as, the
       agreement described in Section 291-f of the Real Property Law of the
       State of New York and shall be entitled to the benefits afforded thereby.

       SECTION 1.13       Restrictions on Transfers and Encumbrances. Except as
expressly permitted hereby or by the Credit Agreement, the Mortgagor shall not
directly or indirectly sell, convey, alienate, assign, lease, sublease, license,
mortgage, pledge, encumber or otherwise transfer, create, consent to or suffer
the creation of any lien, charges or any form of encumbrance upon any interest
in or any part of the Mortgaged Property, or be divested of its title to the
Mortgaged Property or any interest therein in any manner or way, whether
voluntarily or involuntarily (other than resulting from a taking), or engage in
any common, cooperative, joint, time-sharing or other congregate ownership of
all or part thereof.

       SECTION 1.14       Security Agreement. This Mortgage is both a mortgage
and grant of real property and a grant of a security interest in personal
property, and shall constitute and serve as a "Security Agreement" within the
meaning of the Uniform Commercial Code as adopted in the state wherein the
Premises are located (the "UCC"). The Mortgagor hereby grants unto the Mortgagee
a security interest in and to all the Mortgaged Property described in this
Mortgage that is not real property, and simultaneously with the recording of
this Mortgage, the Mortgagor has filed or will file UCC financing statements,
and will file continuation statements prior to the lapse thereof, at the
appropriate offices in the state in which the Premises are located to perfect
the security interest granted by this Mortgage in all the Mortgaged Property
that is not real property. The Mortgagor hereby appoints the Mortgagee as its
true and lawful attorney-in-fact and agent, for the Mortgagor and in its name,
place and stead, in any and all capacities, to execute any document and to file
the same in the appropriate offices (to the extent it may lawfully do so), and
to perform each and every act and thing requisite and necessary to be done to
perfect the security interest hereby granted. The Mortgagee shall

                                       12
<PAGE>   396

have all rights with respect to the part of the Mortgaged Property that is the
subject of a security interest afforded by the UCC in addition to, but not in
limitation of, the other rights afforded the Mortgagee hereunder. Mortgagor
agrees, to the extent permitted by applicable Requirements of Law, that: (i) all
of the goods described within the definition of the word "Personal Property" are
or are to become fixtures on the Land; (ii) this Mortgage upon recording or
registration in the real estate records of the proper office shall constitute a
financing statement filed as a "fixture filing" within the meaning of Sections
9-313 and 9-402 of the UCC and (iii) Mortgagor is the record owner of the
Premises. Additionally, this Mortgage shall constitute a financing statement
covering fixtures and/or minerals or the like (including oil and gas) and/or
accounts resulting from the sale thereof at the wellhead or minehead and, as
such, shall be filed for record in the real estate records of each county in
which the Land, or any part thereof, is located.

       SECTION 1.15       Filing and Recording. The Mortgagor will cause this
Mortgage, any other security instrument creating a security interest in or
evidencing the lien hereof upon the Mortgaged Property and each instrument of
further assurance to be filed, registered or recorded in such manner and in such
places as may be required by any present or future law in order to publish
notice of and to protect fully the liens and security interests of the Mortgagee
hereby granted in and upon the Mortgaged Property. The Mortgagor will pay all
filing, registration or recording fees, and all expenses incidental to the
execution and acknowledgment of this Mortgage, any mortgage supplemental hereto,
any security instrument with respect to the Mortgaged Property, and any
instrument of further assurance and all Federal, state, county and municipal
recording, documentary or intangible taxes and other taxes, duties, imposts,
assessments and charges arising out of or in connection with the execution,
delivery and recording of this Mortgage, any mortgage supplemental hereto, any
security instrument with respect to the Mortgaged Property or any instrument of
further assurance.

       SECTION 1.16       Mortgage of Definite Amount. (a) If, by reason of the
additional sums that may become secured by the lien of this Mortgage pursuant to
the terms hereof, a court or other governmental authority having jurisdiction at
any time shall determine that this Mortgage falls within the limit of Section
256 of the Tax Law of the State of New York, then (subject to Section 1.03
hereof) the Mortgagee reserves the right, in its discretion, to elect not to
have such additional sums secured by this Mortgage and thereby reduce the
Obligations secured hereby to a definite amount equal to the principal amount of
the Obligations, plus any disbursements made to protect the security of this
Mortgage, with interest on such disbursements at the Default Interest Rate, plus
any such other sums as by statute or judicial interpretation now or hereafter
may be permitted to be secured by the lien of a mortgage without incurring any
additional mortgage recording tax. Any election by the Mortgagee to so reduce
the indebtedness secured by this Mortgage shall in no event be deemed a release,
waiver or discharge by the Mortgagee of the Mortgagor's obligation to pay or
reimburse the Mortgagee for such sums.

              (b)    Any sums that may become due and payable pursuant to the
terms of the Credit Agreement, this Mortgage or the other Financing Documents
and that are in the nature of interest (i) shall for the purpose of determining
the amount of mortgage

                                       13
<PAGE>   397

recording tax due and payable on this Mortgage, be considered as additional
interest, whether or not so denominated, (ii) shall be secured by the lien of
this Mortgage to the fullest extent possible without causing this Mortgage to be
covered by Section 256 of the Tax Law of the State of New York and (iii) shall
not be deemed principal and shall not accrue any interest.

       SECTION 1.17       Trust Fund. Pursuant to Section 13 of the Lien Law of
the State of New York, the Mortgagor shall receive the advances secured by this
Mortgage and shall hold such advances as a trust fund to be applied first for
the purpose of paying the cost of any improvement and shall apply such advances
first to the payment of the cost of any such improvement on the Premises before
using any part of the total of the same for any other purpose.

       SECTION 1.18       Further Assurances. Upon demand by the Mortgagee, the
Mortgagor will, at the sole cost of the Mortgagor and without expense to the
Mortgagee, do, execute, acknowledge and deliver all such further acts, deeds,
conveyances, deeds of trust, assignments, notices of assignment, transfers and
assurances as the Mortgagee shall from time to time reasonably require for the
better assuring, conveying, assigning, transferring and confirming unto the
Mortgagee the property and rights hereby conveyed or assigned or intended now or
hereafter so to be, or which the Mortgagor may be or may hereafter become bound
to convey or assign to the Mortgagee, or for carrying out the intention or
facilitating the performance of the terms of this Mortgage, or for filing,
registering or recording this Mortgage, and on demand, the Mortgagor will also
execute and deliver and hereby appoints the Mortgagee as its true and lawful
attorney-in-fact and agent for the Mortgagor and in its name, place and stead,
in any and all capacities, to execute and file to the extent it may lawfully do
so, one or more financing statements, chattel mortgages or comparable security
instruments reasonably required by the Mortgagee to evidence or perfect the
liens and security interests hereby granted and to perform each and every act
and thing requisite and necessary to be done to accomplish the same.

       SECTION 1.19       Additions to Mortgaged Property. All right, title and
interest of the Mortgagor in and to all extensions, improvements, betterments,
renewals, substitutes and replacements of, and all additions and appurtenances
to, the Mortgaged Property hereafter acquired by or released to the Mortgagor or
constructed, assembled or placed by the Mortgagor upon the Premises or the
Improvements, and all conversions of the security constituted thereby,
immediately upon such acquisition, release, construction, assembling, placement
or conversion, as the case may be, and in each such case without any further
mortgage, conveyance, assignment or other act by the Mortgagor, shall become
subject to the liens and security interests of this Mortgage as fully and
completely and with the same effect as though now owned by the Mortgagor and
specifically described in the grant of the Mortgaged Property above, but at any
and all times the Mortgagor will execute and deliver to the Mortgagee any and
all such further assurances, deeds of trust, conveyances or assignments thereof
as the Mortgagee may reasonably require for the purpose of expressly and
specifically subjecting the same to the liens and security interests of this
Mortgage.

                                       14
<PAGE>   398

       SECTION 1.20       No Claims Against the Mortgagee. Nothing contained in
this Mortgage shall constitute any consent or request by the Mortgagee, express
or implied, for the performance of any labor or services or the furnishing of
any materials or other property in respect of the Mortgaged Property or any part
thereof, nor as giving the Mortgagor any right, power or authority to contract
for or permit the performance of any labor or services or the furnishing of any
materials or other property in such fashion as would permit the making of any
claim against the Mortgagee in respect thereof.

       SECTION 1.21       Change in Tax Law. Upon the enactment of or change in
(including, without limitation, a change in interpretation of) any applicable
law (a) deducting or allowing the Mortgagor to deduct from the value of the
Mortgaged Property for the purpose of taxation any lien or security interest
thereon or (b) subjecting the Mortgagee to any tax or changing the basis of
taxation of mortgages, deeds of trust, or other liens or debts secured thereby,
or the manner of collection of such taxes, in each such case, so as to affect
this Mortgage, the Obligations or the Mortgagee, and the result is to increase
the taxes imposed upon or the cost to the Mortgagee of maintaining the
Obligations, or to reduce the amount of any payments receivable hereunder, then,
and in any such event, the Mortgagor shall, on demand, pay to the Mortgagee
additional amounts to compensate for such increased costs or reduced amounts,
provided that if any such payment or reimbursement shall be unlawful, or taxable
to the Mortgagee, or would constitute usury or render the Obligations wholly or
partially usurious under applicable law, then the Mortgagee may, at its option,
declare the Obligations immediately due and payable or require the Mortgagor to
pay or reimburse the Mortgagee for payment of the lawful and non-usurious
portion thereof.

                                   ARTICLE II.
                              DEFAULTS AND REMEDIES

       SECTION 2.01       Events of Default. It shall be an Event of Default
under this Mortgage if any Event of Default (as defined in the Credit Agreement)
shall exist under the Credit Agreement.

       SECTION 2.02       Demand for Payment. Upon the occurrence and during the
continuance of any Event of Default, in addition to any other rights and
remedies Mortgagee may have pursuant to the Financing Documents, or as provided
at law or in equity, and without limitation, the Obligations and all other
amounts payable with respect to this Mortgage shall become due and payable as
provided in the Credit Agreement. The Mortgagor shall pay to the Mortgagee upon
demand all such amounts and such further amounts as shall be reasonably incurred
(without regard to statutory presumption) to cover the costs and expenses of
collection, including reasonable attorneys' fees, disbursements and expenses
incurred by the Mortgagee. Mortgagor hereby waives notice of presentment,
demand, protest, acceleration and notice of acceleration. In case the Mortgagor
shall fail forthwith to pay such amounts or any amounts due under any provision
of this Mortgage upon the Mortgagee's demand, the Mortgagee, in addition to

                                       15
<PAGE>   399

any other rights or remedies provided herein or at law or equity, shall be
entitled and empowered to institute an action or proceedings at law or in equity
as advised by counsel for the collection of the sums so due and unpaid, to
prosecute any such action or proceedings to judgment or final decree, to enforce
any such judgment or final decree against the Mortgagor and to collect, in any
manner provided by law, all moneys adjudged or decreed to be payable.

       SECTION 2.03       Rights to Take Possession, Operate and Apply Revenues.

              (a)    If an Event of Default shall occur and be continuing, the
       Mortgagor shall, upon demand of the Mortgagee forthwith surrender to the
       Mortgagee actual possession of the Mortgaged Property and, if and to the
       extent permitted by applicable law, the Mortgagee itself, or by such
       officers or agents as it may appoint, may then enter and take possession
       of all the Mortgaged Property with or without the appointment of a
       receiver or an application therefor, exclude the Mortgagor and its agents
       and employees wholly therefrom, and have access to the books, papers and
       accounts of the Mortgagor.

              (b)    If the Mortgagor shall for any reason fail to surrender or
       deliver the Mortgaged Property or any part thereof after such demand by
       the Mortgagee as provided in the preceding clause (a), the Mortgagee may
       obtain a judgment or decree conferring upon the Mortgagee the right to
       immediate possession or requiring the Mortgagor to deliver immediate
       possession of the Mortgaged Property to the Mortgagee, to the entry of
       which judgment or decree the Mortgagor hereby specifically consents. The
       Mortgagor will pay to the Mortgagee, upon demand, all reasonable expenses
       of obtaining such judgment or decree, including compensation to the
       Mortgagee's attorneys (for reasonable fees actually incurred (not as
       imposed by statute)) and agents with interest thereon at the Default
       Interest Rate; and subject to the limitations set forth in Section 1.03,
       all such expenses and compensation shall, until paid, be secured by this
       Mortgage.

              (c)    If an Event of Default shall occur and be continuing, the
       Mortgagee may hold, store, use, operate, manage and control the Mortgaged
       Property, conduct the business thereof and, from time to time, (i) make
       all necessary, proper and reasonable maintenance, repairs, renewals,
       replacements, additions, betterments and improvements thereto and
       thereon, (ii) purchase or otherwise acquire additional fixtures,
       personalty and other property, (iii) insure or keep the Mortgaged
       Property insured, (iv) manage and operate the Mortgaged Property and
       exercise all the rights and powers of the Mortgagor to the same extent as
       the Mortgagor could in its own name or otherwise with respect to the same
       or (v) enter into any and all agreements with respect to the exercise by
       others of any of the powers herein granted to the Mortgagee, all as may
       from time to time be directed or determined by the Mortgagee to be in its
       best interest and the Mortgagor hereby appoints the Mortgagee as its true
       and lawful attorney-in-fact and agent, for the Mortgagor and in its name,
       place and stead, in any and all capacities, to perform any of the
       foregoing acts. Regardless of whether or not

                                       16
<PAGE>   400

       Mortgagee has entered or taken possession, the Mortgagee may receive and,
       so long as any Event of Default exists, collect and receive all the
       Rents, issues, profits and revenues from the Mortgaged Property,
       including those past due as well as those accruing thereafter, and, after
       deducting (i) all expenses of taking, holding, managing and operating the
       Mortgaged Property (including compensation for the services of all
       persons employed for such purposes), (ii) the costs of all such
       maintenance, repairs, renewals, replacements, additions, betterments,
       improvements, purchases and acquisitions, (iii) the costs of insurance,
       (iv) such taxes, assessments and other similar charges as the Mortgagee
       may at its option pay, (v) other proper charges upon the Mortgaged
       Property or any part thereof and (vi) the reasonable compensation,
       expenses and disbursements of the attorneys and agents of the Mortgagee,
       the Mortgagee shall apply the remainder of the moneys and proceeds so
       received first to the payment of the Mortgagee for the payment in full
       and satisfaction of the Obligations, and second, if there is any surplus,
       to the Mortgagor, subject to the entitlement of others thereto under
       applicable law.

              (d)    Whenever, before any sale of the Mortgaged Property under
       Section 2.06 hereof, all Obligations that are then due shall have been
       paid and all Events of Default fully cured, the Mortgagee will surrender
       possession of the Mortgaged Property back to the Mortgagor, its
       successors or assigns. The same right of taking possession shall,
       however, arise again if any subsequent Event of Default shall occur and
       be continuing.

       SECTION 2.04       Right to Cure the Mortgagor's Failure to Perform. Upon
the occurrence and during the continuance of an Event of Default, at any time
and without notice, should the Mortgagor fail in the payment, performance or
observance of any term, covenant or condition required by this Mortgage or the
Credit Agreement or any other Financing Document (with respect to the Mortgaged
Property), the Mortgagee may pay, perform or observe the same, and, subject to
the limitations set forth in Section 1.03, all payments made or costs or
expenses incurred by the Mortgagee in connection therewith shall be secured
hereby and shall be, without demand, immediately repaid by the Mortgagor to the
Mortgagee with interest thereon at the Default Interest Rate. The Mortgagee
shall make the determination as to the necessity for any such actions and of the
amounts to be paid. Subject to the notice provisions of the first sentence of
this Section 2.04, to the maximum extent permitted by Requirements of Law, the
Mortgagee is hereby empowered to enter and to authorize others to enter upon the
Premises or the Improvements or any part thereof for the purpose of performing
or observing any such defaulted term, covenant or condition without having any
obligation to so perform or observe and without thereby becoming liable to the
Mortgagor, to any person in possession holding under the Mortgagor or to any
other person.

       SECTION 2.05       Right to a Receiver. If an Event of Default shall
occur and be continuing the Mortgagee, upon application to a court of competent
jurisdiction, shall be entitled as a matter of right to the appointment of a
receiver to take possession of and to operate the Mortgaged Property and to
collect and apply the Rents. The Mortgagor

                                       17
<PAGE>   401

hereby consents to such appointment and acknowledges and agrees that the
Mortgagee shall be entitled to such appointment without notice and without
regard for the adequacy of security for the Obligations or the solvency of the
Mortgagor or any party liable for the Obligations. The receiver shall have all
of the rights and powers permitted under the laws of the state wherein the
Mortgaged Property is located. The Mortgagor will pay to the Mortgagee upon
demand all expenses, including receiver's fees, reasonable attorneys' fees and
disbursements that are actually incurred (not as imposed by statute), costs and
agent's compensation incurred pursuant to the provisions of this Section 2.05;
and, subject to the limitations set forth in Section 1.03, all such expenses
shall be secured by this Mortgage and shall be, without demand, immediately
repaid by the Mortgagor to the Mortgagee with interest thereon at the Default
Interest Rate.

       SECTION 2.06       Foreclosure and Sale.

              (a)    If an Event of Default shall occur and be continuing, the
       Mortgagee may elect to sell the Mortgaged Property or any part of the
       Mortgaged Property by exercise of the power of foreclosure or of sale
       granted to the Mortgagee by applicable law, this Mortgage or the Security
       Agreement. In such case, the Mortgagee may commence a civil action to
       foreclose this Mortgage, or the Mortgagee may proceed and sell the
       Mortgaged Property, in accordance with applicable law, to satisfy any
       Obligation. The Mortgagee or an officer appointed by a judgment of
       foreclosure to sell the Mortgaged Property, may sell all or such parts of
       the Mortgaged Property as may be chosen by the Mortgagee at the time and
       place of sale fixed by it in a notice of sale, either as a whole or in
       separate lots, parcels or items as the Mortgagee shall deem expedient,
       and in such order as it may determine, at public auction to the highest
       bidder. The Mortgagee or an officer appointed by a judgment of
       foreclosure to sell the Mortgaged Property may postpone any foreclosure
       or other sale of all or any portion of the Mortgaged Property by public
       announcement at such time and place of sale, and from time to time as
       permitted by applicable law thereafter may postpone such sale by public
       announcement or subsequently noticed sale. Except as otherwise required
       by Requirements of Law, without further notice, the Mortgagee or an
       officer appointed to sell the Mortgaged Property may make such sale at
       the time fixed by the last postponement, or may, in its discretion, give
       a new notice of sale. Any person, including the Mortgagor or the
       Mortgagee or any designee or affiliate thereof, may purchase any portion
       of the Mortgaged Property at such sale.

              (b)    The Mortgaged Property may be sold subject to unpaid taxes
       and the Permitted Encumbrances, and after deducting all the costs, fees
       and expenses of the Mortgagee, including, without limitation, costs of
       evidence of title in connection with the sale, the Mortgagee or an
       officer that makes any sale shall apply the proceeds of sale in the
       manner set forth in Section 2.08 hereof.

              (c)    Any foreclosure or other sale of less than the whole of the
       Mortgaged Property or any defective or irregular sale made hereunder
       shall not exhaust the power of foreclosure or of sale provided for
       herein; and subsequent

                                       18
<PAGE>   402

       sales may be made hereunder until the Obligations have been satisfied, or
       the entirety of the Mortgaged Property has been sold.

              (d)    If an Event of Default shall occur and be continuing, the
       Mortgagee may instead of, or in addition to, exercising the rights
       described in Section 2.06(a) above and either with or without entry or
       taking possession as herein permitted and as permitted by applicable
       Requirements of Law, proceed by a suit or suits in law or in equity or by
       any other appropriate proceeding or remedy (i) to specifically enforce
       payment of some or all of the terms of the Financing Documents or the
       performance of any term, covenant, condition or agreement of this
       Mortgage or any other right or (ii) to pursue any other remedy available
       to it, at law or in equity, all as the Mortgagee shall determine most
       effectual for such purposes.

       SECTION 2.07       Other Remedies.

              (a)    In case an Event of Default shall occur and be continuing,
       the Mortgagee may also exercise, to the extent not prohibited by
       applicable law, any or all of the remedies available to a secured party
       under the UCC, including, to the extent not prohibited by applicable
       Requirements of Law, the following:

                       (i)     In the case of personal property, exercise those
              rights and remedies under other applicable Security Documents.

                      (ii)     To make such payments and do such acts as the
              Mortgagee may deem necessary to protect its security interest in
              the Personal Property including paying, purchasing, contesting or
              compromising any encumbrance, charge or lien that is prior or
              superior to the security interest granted hereunder, and, in
              exercising any such powers or authority, paying all expenses
              incurred in connection therewith.

                     (iii)     To enter upon any or all of the Premises or
              Improvements to exercise the Mortgagee's rights hereunder.

              (b)    In connection with a sale of the Mortgaged Property and the
       application of the proceeds of sale as provided in Section 2.08 of this
       Mortgage, the Mortgagee shall be entitled to enforce payment of and to
       receive up to the principal amount of the Obligations, plus all other
       charges, payments and costs due under this Mortgage, and to recover a
       deficiency judgment for any portion of the aggregate principal amount of
       the Obligations remaining unpaid, with interest.

       SECTION 2.08       Application of Sale of Proceeds and Rents. After any
foreclosure sale of all or any of the Mortgaged Property, the Mortgagee shall
receive the proceeds of sale, no purchaser shall be required to see to the
application of the proceeds and the Mortgagee shall apply the proceeds of the
sale together with any Rents that may

                                       19
<PAGE>   403

have been collected and any other sums that then may be held by the Mortgagee
under this Mortgage in accordance with the Deposit Account Agreement.

       Upon any sale of the Mortgaged Property by the Mortgagee (including
pursuant to a power of sale granted by statute or under a judicial proceeding),
the receipt of the Mortgagee or of the officer making the sale shall be a
sufficient discharge to the purchaser or purchasers of the Mortgaged Property so
sold and such purchaser or purchasers shall not be obligated to see to the
application of any part of the purchase money paid over to the Mortgagee or such
officer or be answerable in any way for the misapplication thereof.

       SECTION 2.09       The Mortgagor as Tenant Holding Over. If the Mortgagor
remains in possession of any of the Mortgaged Property after any foreclosure
sale by the Mortgagee, at the Mortgagee's election the Mortgagor shall be deemed
a tenant holding over and shall forthwith surrender possession to the purchaser
or purchasers at such sale or be summarily dispossessed or evicted according to
provisions of law applicable to tenants holding over.

       SECTION 2.10       Waiver of Appraisement, Valuation, Stay, Extension and
Redemption Laws.

              (a)    The Mortgagor will not object to any sale of the Mortgaged
       Property pursuant hereto, and for itself and all who may claim under it,
       the Mortgagor waives, to the extent that it lawfully may, all right to
       have the Mortgaged Property marshalled or to have the Mortgaged Property
       sold as separate estates, parcels, tracts or units in the event of any
       foreclosure of this Mortgage.

              (b) To the full extent permitted by applicable Requirements of
       Law, neither the Mortgagor nor anyone claiming through or under it shall
       or will set up, claim or seek to take advantage of any appraisement,
       valuation, stay, extension, homestead-exemption or redemption laws now or
       hereafter in force in order to prevent or hinder the enforcement or
       foreclosure of this Mortgage, the absolute sale of the Mortgaged Property
       or the final and absolute putting of the purchasers into possession
       thereof immediately after any sale; and the Mortgagor, for itself and all
       who may at any time claim through or under it, hereby waives to the full
       extent that it may lawfully do so, the benefit of all such laws and any
       and all right to have the assets covered by the security interest created
       hereby marshalled upon any foreclosure of this Mortgage.

       SECTION 2.11       Discontinuance of Proceedings. In case the Mortgagee
shall proceed to enforce any right, power or remedy under this Mortgage by
foreclosure, entry or otherwise, and such proceedings shall be discontinued or
abandoned for any reason, or shall be determined adversely to the Mortgagee,
then and in every such case the Mortgagor and the Mortgagee shall be restored to
their former positions and rights

                                       20
<PAGE>   404

hereunder, and all rights, powers and remedies of the Mortgagee shall continue
as if no such proceeding had been taken.

       SECTION 2.12       Suits to Protect the Mortgaged Property. During the
continuance of an Event of Default, the Mortgagee shall have power (a) to
institute and maintain suits and proceedings to prevent any impairment of the
Mortgaged Property by any acts which may be unlawful or in violation of this
Mortgage, (b) to preserve or protect its interest in the Mortgaged Property and
in the Rents arising therefrom and (c) to restrain the enforcement of or
compliance with any legislation or other governmental enactment, rule or order
that may be unconstitutional or otherwise invalid if the enforcement of or
compliance with such enactment, rule or order that may be unconstitutional or
otherwise invalid if the enforcement of or compliance with such enactment, rule
or order would impair the security or be prejudicial to the interest of the
Mortgagee hereunder.

       SECTION 2.13       Filing Proofs of Claim. In case of any receivership,
insolvency, bankruptcy, reorganization, arrangement, adjustment, composition or
other proceedings affecting the Mortgagor, the Mortgagee shall, to the extent
permitted by applicable Requirements of Law, be entitled to file such proofs of
claim and other documents as may be necessary or advisable in order to have the
claims of the Mortgagee allowed in such proceedings for the Obligations secured
by this Mortgage at the date of the institution of such proceedings and for any
interest accrued, late charges and additional interest or other amounts due or
that may become due and payable hereunder after such date.

       SECTION 2.14       Possession by the Mortgagee. Notwithstanding the
appointment of any receiver, liquidator or trustee of the Mortgagor, any of its
property or the Mortgaged Property, the Mortgagee shall be entitled, to the
extent not prohibited by applicable law, to remain in possession and control of
all parts of the Mortgaged Property now or hereafter granted under this Mortgage
in accordance with the terms hereof and applicable law.

       SECTION 2.15       Waiver.

              (a)    No delay or failure by the Mortgagee to exercise any right,
       power or remedy accruing upon or during the continuance of any breach or
       Event of Default shall exhaust or impair any such right, power or remedy
       or be construed to be a waiver of any such breach or Event of Default or
       acquiescence therein; and every right, power and remedy given by this
       Mortgage to the Mortgagee may be exercised from time to time and as often
       as may be deemed expedient by the Mortgagee. No consent or waiver by the
       Mortgagee to or of any breach or default by the Mortgagor in the
       performance of the Obligations shall be deemed or construed to be a
       consent or waiver to or of any other breach or Event of Default in the
       performance of the same or any other Obligations by the Mortgagor
       hereunder. No failure on the part of the Mortgagee to complain of any act
       or failure to act or to declare an Event of Default, irrespective of how
       long such

                                       21
<PAGE>   405

       failure continues, shall constitute a waiver by the Mortgagee of its
       rights hereunder or impair any rights, powers or remedies consequent on
       any future Event of Default by the Mortgagor.

              (b)    Even if the Mortgagee (i) grants some forbearance or an
       extension of time for the payment of any sums secured hereby, (ii) takes
       other or additional security for the payment of any sums secured hereby,
       (iii) waives or does not exercise some right granted herein or under the
       Financing Documents, (iv) releases a part of the Mortgaged Property from
       this Mortgage, (v) agrees to change some of the terms, covenants,
       conditions or agreements of any of the Financing Documents, (vi) consents
       to the filing of a map, plat or replat affecting the Premises, (vii)
       consents to the granting of an easement or other right affecting the
       Premises or (viii) makes or consents to an agreement subordinating the
       Mortgagee's lien on the Mortgaged Property hereunder; no such act or
       omission shall preclude the Mortgagee from exercising any other right,
       power or privilege herein granted or intended to be granted in the event
       of any breach or Event of Default then made or of any subsequent default;
       nor, except as otherwise expressly provided in an instrument executed by
       the Mortgagee, shall this Mortgage be altered thereby. In the event of
       the sale or transfer by operation of law or otherwise of all or part of
       the Mortgaged Property, the Mortgagee is hereby authorized and empowered
       to deal with any vendee or transferee with reference to the Mortgaged
       Property secured hereby, or with reference to any of the terms,
       covenants, conditions or agreements hereof, as fully and to the same
       extent as it might deal with the original parties hereto and without in
       any way releasing or discharging any liabilities, obligations or
       undertakings.

       SECTION 2.16       Remedies Cumulative. No right, power or remedy
conferred upon or reserved to the Mortgagee by this Mortgage is intended to be
exclusive of any other right, power or remedy, and each and every such right,
power and remedy shall be cumulative and concurrent and in addition to any other
right, power and remedy given hereunder or now or hereafter existing at law or
in equity or by statute.

                                  ARTICLE III.
                                  MISCELLANEOUS

       SECTION 3.01       Partial Invalidity. If any provision hereof or of any
of the other Financing Documents is invalid or unenforceable in any jurisdiction
or under any circumstances, the other provisions hereof or of those Financing
Documents shall remain in full force and effect in such jurisdiction and the
remaining provisions hereof will be liberally construed in favor of the
Mortgagee in order to carry out the provisions hereof and of such other
Financing Documents. The invalidity of any provision of this Mortgage in any
jurisdiction or under any circumstances will not affect the validity or
enforceability of any such provision in any other jurisdiction or under any
other circumstances. If any lien, encumbrance or security interest evidenced or
created by this Mortgage is invalid or unenforceable, in whole or in part, as to
any part of the

                                       22
<PAGE>   406

Obligations, or is invalid or unenforceable, in whole or in part, as to any part
of the Mortgaged Property, such portion, if any, of the Obligations as is not
secured by all of the Mortgaged Property hereunder shall be paid prior to the
payment of the portion of the Obligations and shall, unless prohibited by
applicable laws or unless Mortgagee, in its sole and absolute discretion,
otherwise elects, be deemed to have been first paid on and applied to payment in
full of the unsecured or partially secured portion of the Obligations, and the
remainder to the secured portion of the Obligations.

       SECTION 3.02       Notices. All communications and notices hereunder
shall be in writing and given as provided in the Credit Agreement.

       SECTION 3.03       Successors and Assigns. All of the grants, covenants,
terms, provisions and conditions herein shall run with the Premises and the
Improvements and shall apply to, bind and inure to, the benefit of the
successors and permitted assigns of the Mortgagor and the successors and assigns
of the Mortgagee.

       SECTION 3.04       Counterparts. This Mortgage may be executed in any
number of counterparts and all such counterparts shall together constitute but
one and the same instrument.

       SECTION 3.05       Satisfaction and Cancellation.

              (a)    The mortgaging to the Mortgagee of the Mortgaged Property
       as security and for the benefit of the Mortgagee created and consummated
       by this Mortgage shall be null and void when all the Obligations (other
       than contingent liabilities that, by their nature, may accrue after
       principal and interest the Obligations have been repaid in full) have
       been indefeasibly paid in full in cash in accordance with the terms of
       the Financing Documents and all Commitments have been terminated.

              (b)    In connection with any termination or release pursuant
       to paragraph (a) to the extent applicable, this Mortgage shall be marked
       "satisfied" by the Mortgagee, and this Mortgage shall be satisfied of
       record at the request and at the expense of the Mortgagor. The Mortgagee
       shall execute any documents reasonably requested by the Mortgagor to
       accomplish the foregoing or to accomplish any release contemplated by
       paragraph (a) or (b) of this Section 3.05 and the Mortgagor will pay all
       costs and expenses, including attorneys' fees and disbursements actually
       incurred (not as imposed by statute), incurred by the Mortgagee in
       connection with the preparation and execution of such documents.

       SECTION 3.06       Definitions. As used in this Mortgage, the singular
shall include the plural as the context requires and the following words and
phrases shall have the following meanings: (a) "including" shall mean "including
but not limited to"; (b) "provisions" shall mean "provisions, terms, covenants
and/or conditions"; (c) "lien" shall mean "lien, charge, encumbrance, security
interest, mortgage or deed of trust"; (d) "obligation" shall mean "obligation,
duty, covenant and/or condition"; and (e) "any of the

                                       23
<PAGE>   407

Mortgaged Property" shall mean "the Mortgaged Property or any part thereof or
interest therein." Any act that the Mortgagee is permitted to perform hereunder
may be performed at any time and from time to time by the Mortgagee or any
person or entity designated by the Mortgagee. Any act which is prohibited to the
Mortgagor hereunder is also prohibited to all lessees of any of the Mortgaged
Property. Each appointment of the Mortgagee as attorney-in-fact for the
Mortgagor under the Mortgage is irrevocable, with power of substitution and
coupled with an interest.

       SECTION 3.07       Other Financing Documents. The Mortgagor acknowledges
that in addition to this Mortgage, other Financing Documents secure the
Obligations. The Mortgagor agrees that the lien of this Mortgage shall be
absolute and unconditional and shall not in any manner be affected or impaired
by any acts or omissions whatsoever of the Mortgagee and, without limiting the
generality of the foregoing, the lien hereof shall not be impaired by any
acceptance by the Mortgagee of any security for or guarantees of any of the
Obligations hereby secured, or by any failure, neglect or omission on the part
of the Mortgagee to realize upon or protect any Obligation hereby secured or any
collateral security therefor including the other Financing Documents. The lien
hereof shall not in any manner be impaired or affected by any release (except as
to the property released), sale, pledge, surrender, compromise, settlement,
renewal, extension, indulgence, alteration, changing, modification or
disposition of any of the Obligations secured or of any of the collateral
security therefor, including the other Financing Documents or of any guarantee
thereof, and the Mortgagee may at its discretion foreclose, exercise any power
of sale, or exercise any other remedy available to it under any or all of the
other Financing Documents without first exercising or enforcing any of its
rights and remedies hereunder. Such exercise of the Mortgagee's rights and
remedies under any or all of the other Financing Documents shall not in any
manner impair the Obligations hereby secured or the lien of this Mortgage and
any exercise of the rights or remedies of the Mortgagee hereunder shall not
impair the lien of any of the other Financing Documents or any of the
Mortgagee's rights and remedies thereunder. The undersigned specifically
consents and agrees that the Mortgagee may exercise its rights and remedies
hereunder and under the other Financing Documents separately or concurrently and
in any order that it may deem appropriate, and the undersigned waives any rights
of subrogation. In the event of a conflict between the terms and provisions of
this Mortgage and the Credit Agreement, both documents shall be read together
and construed, to the fullest extent possible, to be in concert with each other.
In the event of a conflict that cannot be so resolved, the terms and provisions
of the Credit Agreement shall control and govern.

       SECTION 3.08       Subrogation. This Mortgage is made with full
substitution and subrogation of Mortgagee in and to all covenants and warranties
by others heretofore given or made in respect of the Mortgaged Property or any
part thereof.

       SECTION 3.09       Mortgagee Powers. Without affecting the liability of
any other Person liable for the payment of any obligations herein mentioned and
without affecting the lien or charge of this Mortgage upon any portion of the
Mortgaged Property not then or theretofore released as security for the full
amount of all unpaid Obligations,

                                       24
<PAGE>   408

from time to time, regardless of consideration and without notice to or consent
by the holder of any subordinate lien, encumbrance, right, title or interest in
or to the Mortgaged Property, Mortgagee may (a) release any Persons liable for
or on any Obligation, (b) extend the maturity or alter any of the terms of any
Obligation, (c) modify the interest rate payable on the principal balance of the
Obligations, (d) grant other indulgences, (e) release or reconvey, or cause to
be released or reconveyed at any time at Mortgagee's option any parcel, portion
or all of the Mortgaged Property, (f) take or release any other or additional

                             SUBORDINATION AGREEMENT

          SUBORDINATION AGREEMENT dated as of [                     ], [     ],
among [NAME OF SUBORDINATED CREDITOR] (the "Junior Creditor"), BANK OF AMERICA,
N.A., as Administrative Agent (in such capacity, the "Administrative Agent") for
the Lenders (as defined herein), and ORION POWER NEW YORK, L.P., a Delaware
limited partnership (the "Company").

         The Company is party to a Credit Agreement (as amended, renewed,
extended, restated, supplemented or otherwise modified and in effect from time
to time, and includes any agreement extending the maturity of, refinancing or
otherwise restructuring all or any portion of the obligations under such
agreement or any successor agreement, the "Credit Agreement") dated as of July
28, 1999 among the Company (as Borrower), Banc of America Securities LLC and
Paribas, as Lead Arrangers, the financial institutions from time to time party
thereto (the "Lenders"), Bank of America, N.A., as Issuing Bank, and Bank of
America, N.A., as Administrative Agent. The Lenders have severally agreed to
extend credit to the Company pursuant to, and subject to the terms and
conditions specified in, the Credit Agreement. The Junior Creditor desires to
make certain loans to the Company. Under the terms of the Credit Agreement, the
Junior Creditor is permitted to make loans to the Company only if the parties
execute and deliver a Subordination Agreement in the form hereof.

         Accordingly, the Junior Creditor and the Company, intending to be
legally bound, hereby agree with the Administrative Agent, for the benefit of
the Secured Parties, as follows:

                                    ARTICLE I
                                   DEFINITIONS

         SECTION 1.1. Definitions. All capitalized terms used herein and not
otherwise defined herein have the meanings assigned to them in the Credit
Agreement. The following additional terms, as used herein, have the following
meanings:

         "Senior Debt" shall mean (a) all principal of and interest now or
hereafter payable by the Company to the Lenders on or in respect of the Notes

the Company in a bankruptcy case under Title 11 of the United States Code) when
and as due, whether at maturity, by acceleration, upon one or more dates set for
prepayment or otherwise, (b) all Fees and all other fees, expenses, indemnities

Hedge Contracts) and (d) all other indebtedness, obligations and liabilities of
the Company to the Administrative Agent or the Secured Parties

                                        1

<PAGE>   446

under the Financing Documents, now existing or hereafter arising, whether or not
evidenced by notes or other instruments, and whether such indebtedness,
obligations and liabilities are direct or indirect, fixed or contingent,
liquidated or unliquidated, due or to become due, secured or unsecured, joint,
several or joint and several, similar or dissimilar to the indebtedness arising
out of or in connection with the Credit Agreement or of the same or a different
class of indebtedness as the indebtedness arising out of the Credit Agreement,
including, without limitation, loans or advances to the Company after the
commencement by or against the Company of a bankruptcy case under Title 11 of
the United States Code, any overdrafts in any deposit accounts maintained by the
Company including, without limitation, any deposit account maintained pursuant
to the Deposit Account Agreement, any indebtedness of the Company that is
purchased by or assigned to the Administrative Agent or the Lenders and any
indebtedness of the Company to any assignee of all or a portion of the Notes or
any other obligation referred to above, together with all renewals, amendments,
restatements, modifications, extensions, increases or rearrangements thereof.

         "Subordinated Debt" means all indebtedness of the Company to the Junior
Creditor pursuant to [insert description of Subordinated Loans].

                                   ARTICLE II
                                  SUBORDINATION

         SECTION 2.1. Subordination. Notwithstanding any provision to the
contrary in any instrument governing the Subordinated Debt, the Company, the
Junior Creditor and each holder from time to time of the Subordinated Debt by
its acceptance thereof likewise agrees that all payments of the Subordinated
Debt shall be subordinate and subject in right of payment to the prior
indefeasible payment in full in cash of all Senior Debt and to any security held
or to be held by the Administrative Agent for the benefit of the Secured Parties
for the payment of the Senior Debt.

         SECTION 2.2. Priority and Payment Over Upon Insolvency and Dissolution.
In the event of (a) any insolvency or bankruptcy case or proceeding or any
receivership, liquidation, reorganization or similar case or proceeding in
connection therewith relative to the Company or its creditors as such or to its
assets, or (b) any liquidation, dissolution or other winding up of the Company,
whether voluntary or involuntary and whether or not involving insolvency or
bankruptcy, or (c) any assignment for the benefit of creditors or other
marshalling of assets and liabilities of the Company, then and in any such event
the holders of the Senior Debt shall be entitled to receive payment in full in
cash or cash equivalents of all amounts due or to become due on or in respect of
all Senior Debt before the holders of the Subordinated Debt shall be entitled to
receive and retain any payment on account of the principal, interest or other
amounts due or to become due on the Subordinated Debt, and to that end the
holders of the Senior Debt shall be entitled to receive, for application to the
payment of the Senior Debt, any payment or distribution of any kind or
character, whether in cash, property or securities, including any such payment
or distribution which may be payable or deliverable by reason of the payment of
any other indebtedness of the Company which is subordinated to the payment of
the Subordinated

<PAGE>   447

Debt, which may be payable or deliverable in respect of the Subordinated Debt in
any such case, proceeding, dissolution, liquidation or other winding up or
event. Accordingly, any payment or distribution of assets of the Company of any
kind or character, whether in cash, property or securities, which would
otherwise have been made to the holders of the Subordinated Debt but for the
provisions of this Section 2.2 shall instead be made by the Company or by the
trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee, agent
or other Person making payment or distribution of assets of the Company directly
to the holders of the Senior Debt for application to the payment of all Senior
Debt remaining unpaid to the extent necessary to pay all Senior Debt in full in
cash or cash equivalents after giving effect to any concurrent payment or
distribution to or for the benefit of the holders of the Senior Debt.

         If, notwithstanding the foregoing provisions of this Section 2.2, any
holder of the Subordinated Debt shall have received any payment or distribution
of assets of the Company of any kind or character, whether in cash, property or
securities, including any such payment or distribution which may be payable or
deliverable by reason of the payment of any other indebtedness of the Company
which is subordinated to the payment of the Subordinated Debt, before all
amounts due or to become due on or in respect of all Senior Debt have been
indefeasibly paid in full in cash or cash equivalents, then and in such event
such payment or distribution shall be received in trust for the holders of the
Senior Debt and shall be forthwith paid over or delivered by the holder of the
Subordinated Debt receiving the same directly to the holders of the Senior Debt
or, to the extent legally required, to the trustee in bankruptcy, receiver,
liquidating trustee, custodian, assignee, agent or other Person making such
payment or distribution of assets of the Company, for application to the payment
of all Senior Debt remaining unpaid to the extent necessary to pay all Senior
Debt in full in cash or cash equivalents after giving effect to any concurrent
payment or distribution to or for the holders of the Senior Debt.

         For purposes of this Agreement only, the words "cash, property or
securities" shall not be deemed to include shares of stock of, or partnership
interests in, the Company as reorganized or readjusted or unsecured debt
securities of the Company or any other corporation provided for by a plan of
reorganization or readjustment which are subordinated in right of payment to all
Senior Debt which may at the time be outstanding to the same or a greater extent
than the Subordinated Debt is subordinated as provided for in this Agreement.

         SECTION 2.3. Priority and Payment Over Upon Acceleration of the
Subordinated Debt. If any Subordinated Debt is declared due and payable before
the date specified therein as the fixed date on which the principal thereof is
due and payable, then and in such event the holders of the Senior Debt shall be
entitled to receive indefeasible payment in full in cash or cash equivalents of
all amounts due or to become due on or in respect of the Senior Debt before the
holders of the Subordinated Debt shall be entitled to receive and retain any
payment (including any such payment which may be payable by reason of the
payment of any other indebtedness of the Company which is subordinated to the
payment of the Subordinated Debt) by the Company on account of the principal of,
interest on or any other amount due or to become due on the Subordinated Debt or
on account of the purchase or other acquisition of the Subordinated Debt.
Accordingly, any payment by the Company of any amount which the holders of the
Subordinated

<PAGE>   448

Debt would have been entitled to receive and retain but for the provisions of
this Section 2.3 shall instead be made by the Company directly to the holders of
the Senior Debt for application to the payment of all Senior Debt remaining
unpaid to the extent necessary to pay all Senior Debt in full in cash or cash
equivalents after giving effect to any concurrent payment or distribution to or
for the holders of the Senior Debt.

         If, notwithstanding the foregoing provisions of this Section 2.3, any
holder of the Subordinated Debt shall have received any payment, including any
payment which may be payable by reason of the payment of any other indebtedness
of the Company which is subordinated to the payment of the Subordinated Debt,
before all amounts due or to become due on or in respect of the Senior Debt have
been paid in full in cash or cash equivalents, then and in such event such
payment shall be received in trust for the holders of the Senior Debt and shall
be forthwith paid over by the holder of the Subordinated Debt receiving such
payment to the holders of the Senior Debt for application to the payment of all
Senior Debt remaining unpaid to the extent necessary to pay all Senior Debt in
full in cash or cash equivalents after giving effect to any concurrent payment
or distribution to or for the holders of the Senior Debt.

         The provisions of this Section 2.3 above shall not apply to any payment
or distribution with respect to which Section 2.2 would be applicable.

         SECTION 2.4. Payment on Subordinated Debt Suspended When Senior Debt is
in Default. In addition to the limitations on payment of the Subordinated Debt
as set forth in Section 2.6, in the event that any Default or Event of Default
with respect to any Senior Debt shall have occurred and be continuing, then
unless and until such Default or Event of Default shall have been cured or
waived or shall have ceased to exist and any acceleration resulting therefrom
shall have been rescinded or annulled, or in the event any judicial proceeding
shall be pending with respect to any such Default or Event of Default, then no
payment (including any payment which may be payable by reason of the payment of
any other indebtedness of the Company which is subordinated to the payment of
the Subordinated Debt) shall be made by the Company on account of the principal
of or interest on the Subordinated Debt or on account of the purchase or other
acquisition by it of the Subordinated Debt.

         If, notwithstanding the foregoing provisions of this Section 2.4, the
Company shall make any payment or distribution on or with respect to any
Subordinated Debt prohibited by the foregoing provisions of this Section 2.4,
then and in every such event such payment or distribution shall be forthwith
paid over or delivered by the holders of the Subordinated Debt to the
Administrative Agent for the benefit of the Lenders.

         The provisions of this Section 2.4 shall not apply to any payment with
respect of which Section 2.2 or 2.3 would be applicable.

         SECTION 2.5. Obligation to Pay Subordinated Debt Not Impaired;
Provisions to Define Relative Rights. Except as provided in this Article II, the
provisions of this Agreement are and are intended solely for the purpose of
defining the relative rights of the holders of the Subordinated Debt on the one
hand and the holders of the Senior Debt on the other hand. It is

<PAGE>   449

and shall be the intent of the parties that this Subordination Agreement shall
constitute a present assignment by the holders of the Subordinated Debt of their
rights to receive payments or distributions of cash, property and securities of
the Company otherwise payable to the holders of the Subordinated Debt in the
circumstances described in Sections 2.2 and 2.3 hereof. Nothing contained in
this Subordination Agreement, except as set forth in Section 2.4 and Section
2.6, shall (a) impair or affect, as among the Company, its creditors (other than
the holders of the Senior Debt) and the holders of the Subordinated Debt, the
obligation of the Company to pay the holders of the Subordinated Debt the
principal of and interest on the Subordinated Debt as of when the same shall
become due and payable in accordance with their terms, or (b) affect the
relative rights against the Company of the holders of the Subordinated Debt and
the creditors of the Company (other than the holders of the Senior Debt).

         SECTION 2.6. Payments on Subordinated Debt. Subject to the terms of
this Article II and as long as no Default or Event of Default exists in the
Credit Agreement, payments on the Subordinated Debt can be made by the Company
to the Junior Creditor out of cash flow available for Permitted Distributions if
and only if all conditions precedent for a Permitted Distribution as set forth
in the Financing Documents have been met and the Company directs the
Administrative Agent, in writing, to pay cash otherwise available for a
Permitted Distribution under the terms of the Credit Agreement and the Deposit
Account Agreement to the holders of the Subordinated Debt. The Junior Creditor
and the Company hereby agree and acknowledge that the Company's obligations to
repay the principal of, the interest on, and all other obligations incurred by
the Company in connection with, the Subordinated Debt are limited to the
Company's cash flow available for Permitted Distributions pursuant to the terms
of the Financing Documents and actually distributed by the Company (or that
would have been distributed but for a direction to pay the Subordinated Debt as
set forth herein) and that the Company shall have no other means for repaying
such obligations.

                                   ARTICLE III
                         IN FURTHERANCE OF SUBORDINATION

         SECTION 3.1. Restriction on Assignment of Subordinated Debt. The Junior
Creditor and each holder of the Subordinated Debt by its acceptance thereof
agrees not to sell, assign or transfer all or any part of the Subordinated Debt
while any Senior Debt remains unpaid unless such sale, assignment or transfer is
made expressly subject to this Subordination Agreement. The Junior Creditor
represents that no other subordination of the Subordinated Debt is in existence
on the date hereof, and the Junior Creditor agrees that the Subordinated Debt
will not be subordinated to any indebtedness owed to any Person other than the
Lenders.

         SECTION 3.2. Reliance on Subordination. The Junior Creditor and each
holder of the Subordinated Debt by its acceptance thereof consents and agrees
that all Senior Debt shall be deemed to have been made or incurred in reliance
upon the subordination of the Subordinated Debt pursuant to this Subordination
Agreement.

<PAGE>   450

         SECTION 3.3. Actions Against the Company. No holder of the Subordinated
Debt will (a) commence any action or proceeding against the Company to recover
all or any part of such Subordinated Debt or (b) join with any creditor in
bringing any proceeding against the Company under Title 11 of the United States
Code or any other state or federal insolvency statute and until, in each case,
the Senior Debt shall have been indefeasibly paid in full (provided that holders
of the Subordinated Debt may so file concurrently with or after the holders of
the Senior Debt). Except pursuant to Section 2.6, the Junior Creditor and each
other holder of the Subordinated Debt will not ask, demand, sue for, take or
receive from the Company, directly or indirectly, in cash, property or
securities or other property or by set-off or in any other manner (including,
without limitation, from or by way of collateral), payment of all or any part of
the Subordinated Debt unless and until all Senior Debt shall have been
indefeasibly paid in full or the benefits of this sentence waived by or on
behalf of the holder or holders of the Senior Debt.

         SECTION 3.4. Subrogation. Subject to the indefeasible payment in full
in cash or cash equivalents of all Senior Debt, the holders of the Subordinated
Debt shall be subrogated to the extent of the payments or distributions made to
the holders of the Senior Debt pursuant to the provisions of this Agreement
(equally and ratably with the holders of all indebtedness of the Company which
by its express terms is subordinated to indebtedness of the Company
substantially to the extent that the Subordinated Debt is subordinated hereunder
and is entitled to like rights of subrogation) to the rights of the holders of
such Senior Debt to receive payments and distributions of cash, property and
securities applicable to the Senior Debt until the principal of and interest on
the Subordinated Debt and all other obligations, monetary or otherwise, or
liabilities now or hereafter arising related to the Subordinated Debt shall be
paid in full. For purposes of such subrogation, no payments or distributions to
the holders of the Senior Debt of any cash, property or securities to which the
holders of the Subordinated Debt would be entitled but for the provisions of
this Agreement, and no payments over, pursuant to the provisions of Section 2.2
or 2.3, to the holders of the Senior Debt by the holders of the Subordinated
Debt shall, as among the Company, its creditors (other than the holders of
Senior Debt) and the holders of the Subordinated Debt, be deemed to be a payment
or distribution by the Company to or on account of the Senior Debt.

         SECTION 3.5. Proofs of Claim. The Junior Creditor may file such proofs
of claim and other papers or documents or may be necessary or advisable in order
to have the claims of the Junior Creditor allowed in any judicial proceedings
relative to the Company (or any other obligor on the Subordinated Debt,
including any guarantor), its creditors or its property. If the Junior Creditor
files any claim, proof of claim or similar instrument in any judicial proceeding
referred to above and all Senior Debt has not been indefeasibly paid in full in
cash or cash equivalents, the Junior Creditor shall (a) file such claim, proof
of claim or similar instrument on behalf of the Lenders and the other holder or
holders of the Senior Debt as it or such other holder's or holders' interests
may appear and (b) take all such other actions as may be appropriate to insure
that all payments and distributions made in respect of any such proceedings are
made to the Lenders and any other holder or holders of the Senior Debt as it or
their interests may appear.

Any term or provision of this Section 3.5 to the contrary notwithstanding, if
any judicial proceeding referred to above is commenced by or against the
Company, and so long as all Senior

<PAGE>   451

Debt has not been paid in full: (a) the Administrative Agent is hereby
irrevocably authorized and empowered (in its own name or in the name of the
Junior Creditor or otherwise), but shall have no obligation, to demand, sue for,
collect and receive every payment or distribution received in respect of any
such proceeding and give acquittance therefor and to file claims and proofs of
claims and (b) the Junior Creditor shall duly and promptly take, for the account
of the Lenders and any other holders of the Senior Debt, such reasonable action
as the Lenders may request (i) to collect all amounts payable by the Company in
respect of the Subordinated Debt and to file the appropriate claims or proofs of
claim in respect of the Subordinated Debt, (ii) to execute and deliver to the
Administrative Agent on behalf of the Lenders such assignments or other
instruments as the Lenders may request in order to enable the Lenders to enforce
any and all claims with respect to all amounts payable in respect of the
Subordinated Debt and (iii) to collect and receive any and all payments with
respect to all amounts payable in respect of the Subordinated Debt. Until the
Senior Debt has been paid in full, no holder of the Subordinated Debt will (in
any proceeding of the type described in Section 2.2) discharge all or any
portion of the obligations of the Company in respect of the Subordinated Debt,
whether by forgiveness, receipt of capital stock, exercise of conversion
privileges or otherwise, without the prior consent of the holders of the Senior
Debt.

         SECTION 3.6. Certain Proceedings. Each holder of the Subordinated Debt
agrees that, as between themselves and the holders of the Senior Debt, the
latter shall be deemed to be the "holders" of all claims in respect of the
Subordinated Debt in any proceeding of the type contemplated by clause (a), (b)
or (c) of Section 2.2 (each, a "bankruptcy proceeding"). To the extent not
deemed to be "not in good faith" within the meaning of 11 U.S.C. Section
1126(e), each holder of the Subordinated Debt agrees to vote to accept a plan of
reorganization or dissolution in respect of the Company which the holders of the
Senior Debt have accepted or have notified the holders of the Subordinated Debt
of their intent to accept. If such acceptance by the holders of the Subordinated
Debt is or might (in the sole judgment of the holders of the Senior Debt) cause
the claims of the holders of the Subordinated Debt to be designated under 11
U.S.C. Section 1126(e), then, each holder of the Subordinated Debt agrees not to
vote against a plan of reorganization or dissolution which the holders of the
Senior Debt have accepted or have notified the holders of the Subordinated Debt
of their intent to accept. Any such vote for any plan or abstention from voting
against any plan pursuant to the immediately two preceding sentences shall be
enforceable by the holders of the Senior Debt against the holders of the
Subordinated Debt regardless of whether such plan allows a class subordinated to
the claims of the Subordinated Debt to retain an interest in the Company or
whether the holders of the Subordinated Debt will receive or retain under such
plan on account of their claims in respect of the Subordinated Debt property
having value less than the amount that such holders would receive or retain if
the Bankruptcy Proceeding were under Chapter 7 of the federal Bankruptcy Code.

                                   ARTICLE IV
                                  MISCELLANEOUS

         SECTION 4.1. Changes. The Administrative Agent, on behalf of the
Lenders, may at any time, and from time to time, without the consent of or
notice to the Junior Creditor or to any other holder of the Subordinated Debt,
without incurring responsibility to the Junior Creditor or such holder, and
without impairing or releasing any of the Lender's rights, or any of the
obligations of the Junior Creditor or other holders of the Subordinated Debt
hereunder:

                  (a)    change the time, amount, manner, place or terms of
         payment, or change or extend the time of payment of, or renew or
         otherwise alter, the Credit Agreement or any other Financing Document
         or any instrument or agreement evidencing any Senior Debt or securing
         payment thereof or relating to the Senior Debt in any manner;

                  (b)    sell, exchange, release or otherwise deal with any
         collateral for all or any of the Senior Debt (whether or not in a
         commercially reasonable manner);

                  (c)    release anyone liable in any manner for the payment or
         collection of any Senior Debt;

                  (d)    exercise or refrain from exercising any rights against
         the Company or others (including the Junior Creditor);

                  (e)    apply any sums received by the Administrative Agent or
         any Lenders, by whomsoever paid and however realized, to the payment of
         the Senior Debt in such manner as the Administrative Agent, in its sole

Administrative Agent: (a) any Person shall have filed (and not released within
such 45 day period) a lawsuit or lawsuits against any Borrower Entity where the
amount in controversy is in excess of $10,000,000 in the aggregate, unless
Acceptable Reserves described in clauses (i) and (ii) of the definition thereof

payable by the applicable Borrower Entity as a result of such lawsuit are
adequately covered by insurance, (b) any Event of Default (unless cured within
the applicable 45 day period referred to above), (c) the failure of the Borrower

relating to any Indebtedness for borrowed money of the Sponsor in excess of
$5,000,000, (b) the failure of the Sponsor to observe or perform any covenant or
agreement (other than as described in clause (II)(a) above or (II)(c) below) in
any document or instrument relating to any Indebtedness for borrowed money of
the Sponsor in excess of $5,000,000, after the expiration of any applicable cure
period, provided, that if no cure period is so provided the Borrower shall have
10 Business Days to cure such failure or (c) 15 days after the failure of the
Sponsor to comply with the financial covenants described in Section 5 of the
Holding Company Agreement as reported pursuant to the Sponsor's delivery of its
quarterly financial statements under the Corporate Revolver (as defined in the
Holding Company Agreement); provided, that, in the event that any failure
described in clauses (II)(a), (b) and (c) above shall have occurred and the
Administrative Agent shall have made the demand described in clause (II) above,
if the Sponsor then cures such failure within the stated five (5) Business Days
after delivery of such demand, such demand shall be deemed rescinded.

If the Borrower or Sponsor, as the case may be, shall fail to comply with the
requirements of this Section 5.28, the Administrative Agent (on behalf of the
Secured Parties) shall be entitled to make Working Capital Advances and/or
offset funds on deposit in the Accounts to pay the fees and taxes associated
with the Astoria Supplemental Mortgage (and the related title insurance) and
record the same. Nothing contained in the previous sentence shall in any manner
limit other remedies available to the Secured Party under the Financing
Documents."

         SECTION 1.04 Amendment to Section 6.05. Section 6.05(b) of the Credit
Agreement is hereby amended by adding the following phrase after the word

Separateness/Operations Matters; Effect of Bankruptcy, Death or Incompetency of
the Limited Partner; and Transfer of Ownership Interests in Partnership] of
their respective Partnership Agreements and (ii) the General Partner may not
amend or modify Sections [Purpose; Independent Director; Separateness/Operations
Matters; and Transfer of Ownership Interests in Corporation] of its Governing
Documents"

         SECTION 1.05 Amendments to Section 7.09. Section 7.09 of the Credit
Agreement is hereby amended by deleting the word "CPS" in clauses (b)(i)(A) and
(b)(i)(D) thereof and, in each case, substituting the words "Constellation
Energy Group" in lieu thereof.

         SECTION 1.06 Consent to Temporary Fuel Contract. The undersigned hereby
consent to Astoria Generating's execution and delivery of the Second Sempra
Agreement, a copy of which is attached hereto as Exhibit A. Further, it is
understood and agreed by the parties hereto that the Second Sempra Agreement
will not constitute an Additional Contract for purposes of the Credit Agreement.

         SECTION 1.07 Representations and Warranties. The Borrower hereby
represents and warrants to each Lender and the Administrative Agent, upon
execution and delivery of this Third Amendment, as follows:

                  (a) The representations and warranties set forth in Article IV
of the Amended Agreement, and in each other Financing Document, are true and
correct in all material respects on and as of the date hereof and on and as of
the Third Amendment Effective Date (as hereinafter defined) with the same effect
as if made on and as of the date hereof or the Third Amendment Effective Date,
as the case may be, except to the extent such representations and warranties
expressly relate solely to an earlier date.

                  (b) Each of the Borrower and the other Credit Parties is in
compliance with all the terms and conditions of the Amended Agreement and the
other Financing Documents on its part to be observed or performed and no Event
of Default has occurred and is continuing.

                  (c) The execution, delivery and performance by the Borrower of
this Third Amendment have been duly authorized by the Borrower.

<PAGE>   483

                  (d) This Third Amendment constitutes the legal, valid and
binding obligation of the Borrower, enforceable against it in accordance with
its terms.

                  (e) The execution, delivery and performance by the Borrower of
this Third Amendment (i) do not and will not contravene (A) its Governing
Documents or (B) any material Requirement of Law, any material Contractual
Obligation or any material Governmental Approval binding on or affecting it and
(ii) do not and will not conflict with or be inconsistent with or result in any
breach of any of the terms, covenants, conditions or provisions of, or
constitute a default under, or result in the creation or imposition or (or the
obligation to create or impose) any Lien (except Permitted Liens) upon any of
its properties or assets pursuant to, the terms of any material Contractual
Obligation binding on or affecting it.

         SECTION 1.08 Effectiveness. This Third Amendment shall become effective
only upon satisfaction of the following conditions precedent (the first date
upon which each such condition has been satisfied being herein called the "Third
Amendment Effective Date"):

                  (a) The Administrative Agent shall have received duly executed
counterparts of this Third Amendment which, when taken together, bear the
authorized signatures of the Borrower and the Required Lenders.

                  (b) The Administrative Agent and the Lenders shall be
satisfied that the representations and warranties set forth in Section 1.07 of
this Third Amendment are true and correct on and as of the Third Amendment
Effective Date and that no Default or Event of Default has occurred and is
continuing.

                  (c) The Holding Company Agreement shall have been executed and
delivered by each party thereto and shall be in full force and effect.

                  (d) There shall not be any action pending or any judgment,
order or decree in effect which, in the judgment of the Administrative Agent or
the Lenders, is likely to restrain, prevent or impose materially adverse
conditions upon performance by the Borrower or any other Credit Party of its
obligations under the Amended Agreement.

                  (e) The Administrative Agent shall have received such other
documents, legal opinions, instruments and certificates relating to this Third

                           amended, modified or otherwise supplemented through
                           the date hereof, the "Credit Agreement") among the
                           Borrower, Banc of America Securities LLC and Paribas,
                           as lead arrangers (collectively, the "Lead

                           Agent.

         The Borrower Entities have requested the Administrative Agent to make
certain changes to the Deposit Account Agreement. The parties hereto have
agreed, subject to the terms and conditions hereof, to amend the Deposit Account
Agreement as provided herein.

         Capitalized terms used herein and not otherwise defined herein shall
have the meanings assigned to such terms in the Deposit Account Agreement (the
Deposit Account Agreement, as amended by, and together with, this First
Amendment, and as hereinafter amended, modified, extended or restated from time
to time, being called the "Amended Agreement") or if not defined therein, then
in the Credit Agreement.

         Accordingly, the parties hereto hereby agree as follows:

         Section 1.01 Amendments to Section 5.2. Section 5.2(d), (f) and (j) of
the Deposit Account Agreement are hereby deleted in their entirety and the
following are hereby substituted in lieu thereof respectively:

         "(d) On the last Business Day of each month, the Administrative Agent
shall withdraw funds out of funds then available in the Revenue Account (after
making any pending withdrawals required under clauses (a) through (c) of this
Section 5.2) and shall deposit such withdrawn funds into the Debt Service
Account in an amount up to the Scheduled Debt Service Deposit Amount applicable
to the immediately succeeding month; provided however, that in the event funds
on deposit in the Revenue Account on the last Business Day of such month are
insufficient to fund the Scheduled Debt Service Deposit Amount applicable to
such succeeding month (any such insufficiency together with any other similar
insufficiencies from prior months, the "Debt

<PAGE>   496

Service Account Shortfall"), the Borrower shall, to the extent funds are
available in the Revenue Account, deposit in such succeeding month, out of funds
then available in the Revenue Account (after making any pending withdrawals
required under clauses (a) through (c) of this Section 5.2) an additional amount
pursuant to this clause (d) up to such Debt Service Account Shortfall on the
last Business Day of such succeeding month."

         "(f) On each Semi-Annual Date, the Administrative Agent shall withdraw
out of funds then available in the Revenue Account (after making any pending
withdrawals required under subsections (a) through (e) of this Section 5.2) and
shall deposit into the Debt Service Reserve Account funds up to an amount equal
to the Debt Service Reserve Requirement Shortfall."

         "(j) On each Distribution Date on or prior to the Final Distribution
Date, the Administrative Agent shall withdraw out of funds then available in the
Revenue Account which constitute Net Distribution Amounts and shall deposit into
the O&M Reserve Account funds up to an amount equal to any O&M Reserve
Requirement Shortfall."

         Section 1.02 Amendment to Section 9.1 and Related Schedule I. (a)
Section 9.1(e) of the Deposit Account Agreement is hereby deleted in its
entirety and the following is hereby substituted in lieu thereof:

         "(e)     Local Operating Accounts.

                  (i) The Borrower shall close each Local Operating Account
listed on Part A of Schedule I hereto as soon as practicable after the date
hereof. Until such date as such accounts shall have been closed pursuant to the
preceding sentence, no Borrower Entity shall permit the aggregate amount on
deposit at any time in such accounts to exceed $50,000. From and after the date
on which such accounts shall have been closed, no Borrower Entity shall open or
permit to exist any Local Operating Account other than those set forth on Part B
to Schedule I hereto without the prior consent of the Administrative Agent.

                  (ii) No Borrower Entity shall permit the amount on deposit at
any time in the Local Operating Account to exceed (a) $15,000 for Carr Street
Generating Station, L.P. debit account; (b) $50,000 for the Erie Boulevard
Hydropower, L.P. debit account; (c) $25,000 for the Astoria Generating Company,
L.P. debit account or (d) $75,000 in the aggregate for all such accounts."

                  (b) Schedule I attached to this First Amendment is hereby
         adopted as Schedule I for purposes of Section 9.1(e) of the Amended
         Agreement.

         Section 1.03 Representations and Warranties. Each Borrower Entity
hereby represents and warrants to each Lender and the Administrative Agent, upon
execution and delivery of this First Amendment, as follows:

                  (a) The representations and warranties set forth in Article
         VIII of the Amended Agreement, and in each other Financing Document,
         are true and correct in all material respects on and as of the date
         hereof and on and as of the First Amendment Effective Date (as
         hereinafter defined) with the same effect as if made on and as of the
         date hereof

                                       2
<PAGE>   497

         or the First Amendment Effective Date, as the case may be, except to
         the extent such representations and warranties expressly relate solely
         to an earlier date.

                  (b) Such Borrower Entity is in compliance with all the terms
         and conditions of the Amended Agreement and the other Financing
         Documents on its part to be observed or performed and no Event of
         Default has occurred and is continuing.

                  (c) The execution, delivery and performance by such Borrower
         Entity of this First Amendment have been duly authorized by such
         Borrower Entity.

                  (d) This First Amendment constitutes the legal, valid and
         binding obligation of such Borrower Entity, enforceable against it in
         accordance with its terms.

                  (e) The execution, delivery and performance by such Borrower
         Entity of this First Amendment (i) do not and will not contravene (A)
         its Governing Documents or (B) any material Requirement of Law, any
         material Contractual Obligation or any material Governmental Approval
         binding on or affecting it and (ii) do not and will not conflict with
         or be inconsistent with or result in any breach of any of the terms,
         covenants, conditions or provisions of, or constitute a default under,
         or result in the creation or imposition or (or the obligation to create
         or impose) any Lien (except Permitted Liens) upon any of its properties
         or assets pursuant to, the terms of any material Contractual Obligation
         binding on or affecting it.

         Section 1.04 Effectiveness. This First Amendment shall become effective
only upon satisfaction of the following conditions precedent (the first date
upon which each such condition has been satisfied being herein called the "First
Amendment Effective Date"):

                  (a) The Administrative Agent shall have received duly executed
         counterparts of this First Amendment which, when taken together, bear
         the authorized signatures of each Borrower Entity and the
         Administrative Agent.

                  (b) The Administrative Agent shall have received the written
         consent of the Required Lenders to the terms and conditions of this
         First Amendment as required by Section 9.02 of the Credit Agreement.

                  (c) The Administrative Agent and the Lenders shall be
         satisfied that the representations and warranties set forth in Section
         1.03 of this First Amendment are true and correct on and as of the
         First Amendment Effective Date and that no Default or Event of Default
         has occurred and is continuing.

                  (d) There shall not be any action pending or any judgment,
         order or decree in effect which, in the judgment of the Administrative
         Agent or the Lenders, is likely to restrain, prevent or impose
         materially adverse conditions upon performance by any Borrower Entity
         of its obligations under the Amended Agreement.

                  (e) The Administrative Agent shall have received such other
         documents, legal opinions, instruments and certificates relating to

         reasonably request and such other documents, legal opinions,
         instruments and certificates shall be satisfactory in form and
         substance to the Administrative Agent and the Lenders. All partnership
         and other proceedings taken or to be taken in connection with this
         First Amendment and all documents incidental thereto, whether or not
         referred to herein, shall be satisfactory in form and substance to the
         Administrative Agent and the Lenders.

                  (f) The Borrower shall have paid all fees and expenses
         referred to in Section 1.06 of this First Amendment.

         Section 1.05 Governing Law; Submission to Jurisdiction; Waiver of Jury

                  (a) THIS FIRST AMENDMENT SHALL BE GOVERNED BY AND INTERPRETED
         IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK OTHER THAN ANY
         SUCH REQUIREMENT OF LAWS THAT WOULD APPLY THE LAWS OF ANOTHER
         JURISDICTION, EXCEPT TO THE EXTENT THAT THE LAWS OF ANOTHER
         JURISDICTION ARE MANDATORILY APPLICABLE. ANY DISPUTE ARISING OUT OF,
         CONNECTED WITH, RELATED TO, OR INCIDENTAL TO THE RELATIONSHIP
         ESTABLISHED BETWEEN THE BORROWER OR THE BORROWER ENTITIES AND THE
         ADMINISTRATIVE AGENT (COLLECTIVELY, THE "FIRST AMENDMENT PARTIES") IN
         CONNECTION WITH THIS FIRST AMENDMENT AND THE OTHER FINANCING DOCUMENTS,
         AND WHETHER ARISING IN CONTRACT, TORT, EQUITY OR OTHERWISE, SHALL BE
         RESOLVED IN ACCORDANCE WITH THE INTERNAL LAWS (AS OPPOSED TO THE
         CONFLICTS OF LAWS PROVISIONS) AND DECISIONS OF THE STATE OF NEW YORK.

                  (b) EACH OF THE FIRST AMENDMENT PARTIES AGREE THAT ALL
         DISPUTES BETWEEN THEM ARISING OUT OF, CONNECTED WITH, RELATED TO, OR
         INCIDENTAL TO THE RELATIONSHIP ESTABLISHED BETWEEN THEM IN CONNECTION
         WITH THIS FIRST AMENDMENT, AND WHETHER ARISING IN CONTRACT, TORT,
         EQUITY, OR OTHERWISE, SHALL BE RESOLVED ONLY BY STATE OR FEDERAL COURTS
         LOCATED IN NEW YORK, NEW YORK, BUT EACH OF THE FIRST AMENDMENT PARTIES
         ACKNOWLEDGE THAT ANY APPEALS FROM THOSE COURTS MAY HAVE TO BE HEARD BY
         A COURT LOCATED OUTSIDE OF NEW YORK, NEW YORK. EACH BORROWER ENTITY
         WAIVES IN ALL DISPUTES ANY OBJECTION THAT IT MAY HAVE TO THE LOCATION
         OF THE COURT CONSIDERING THE DISPUTE INCLUDING, WITHOUT LIMITATION, ANY
         OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON
         CONVENIENS.

                  (c) THE FIRST AMENDMENT PARTIES EACH WAIVE ANY RIGHT TO HAVE A
         JURY PARTICIPATE IN RESOLVING ANY DISPUTE, WHETHER SOUNDING IN
         CONTRACT, TORT, OR OTHERWISE ARISING OUT OF, CONNECTED WITH, RELATED TO
         OR INCIDENTAL TO THE RELATIONSHIP ESTABLISHED BETWEEN THEM IN
         CONNECTION WITH THIS FIRST

                                       4

         Section 1.06 Expenses. The Borrower shall pay all reasonable
out-of-pocket expenses incurred by the Administrative Agent and the Lenders in
connection with the preparation, negotiation, execution, delivery and
enforcement of this First Amendment, including, but not limited to, the
reasonable fees and disbursements of counsel to the Administrative Agent.

         Section 1.07 Counterparts. This First Amendment may be executed in any
number of counterparts and by the different parties hereto in separate
counterparts, each of which when so executed and delivered shall be an original,
but all of which shall together constitute one and the same instrument.

         Section 1.08 Severability. In case any provision in or obligation under
this First Amendment or the other Financing Documents shall be invalid, illegal
or unenforceable in any jurisdiction, the validity, legality and enforceability
of the remaining provisions or obligations, or of such provision or obligation
in any other jurisdiction, shall not in any way be affected or impaired thereby.

         Section 1.09 Benefit of Agreement. This First Amendment shall be
binding upon and inure to the benefit of and be enforceable by the respective
successors and assigns of the parties hereto; provided that no Borrower Entity
may assign or transfer any of its interest hereunder without the prior written
consent of the Lenders.

         Section 1.10 Integration. This First Amendment represents the agreement
of the Borrower Entities and the Administrative Agent, with respect to the
subject matter hereof, and there are no promises, undertakings, representations

                  outstanding; provided, that, failure by such Acquisition
                  Lender to make any such annotation or any error therein shall
                  not affect the obligations of the Borrower hereunder or under
                  such Acquisition Loan Note in respect of such Acquisition Loan
                  Advances evidenced thereby. Each Acquisition Lender is hereby
                  irrevocably authorized by the Borrower to endorse its
                  Acquisition Loan Note and to attach to and make a part of its
                  Acquisition Loan Note a continuation of such schedule as and
                  when required.

                  (c) Type of Acquisition Loan Advances. All or any portion of
Acquisition Loan Advances shall be either Base Rate Advances or LIBO Rate
Advances and may be Converted or continued from time to time pursuant to Section
2.04.

                  (e) Repayment of Acquisition Loans. On each Quarterly Payment
Date, the Borrower shall repay the Acquisition Loans in accordance with the
terms of the Deposit Account Agreement. On the Final Maturity Date, the Borrower
shall repay the aggregate principal amount of all Acquisition Loans outstanding
on such date.

                  Section 2.02  Revolving Loans.

                  (a) Revolving Loan Commitments

                           (i) Subject to the terms and conditions of this
                  Agreement and relying on the representations and warranties
                  set forth herein, each Revolving Lender severally agrees to
                  make Revolving Advances to the Borrower, during the Revolving
                  Loan Availability Period on any Revolving Loan Funding Date,
                  in an amount equal to its Pro Rata Share of the Revolving Loan
                  requested to be made on such date, but in no event shall the
                  sum of (x) any Revolving Advance made by any Revolving Lender
                  as of any date, plus (y) the aggregate principal amount of
                  Revolving Advances previously made by such Revolving Lender
                  that

                                       36
<PAGE>   43

                  remain outstanding and unpaid as of such date, plus (z) such
                  Revolving Lender's Letter of Credit Exposure on such date,
                  exceed such Revolving Lender's Revolving Loan Commitment. As
                  of any date, the aggregate amount of all Revolving Advances
                  made by all Revolving Lenders hereunder and that remain
                  outstanding and unpaid from time to time plus the aggregate
                  amount of all Letter of Credit Exposure on such date, shall
                  not in any event exceed the Maximum Revolving Loan Amount.
                  Unless earlier terminated in accordance herewith, the
                  Revolving Loan Commitments shall terminate in their entirety
                  on the Final Maturity Date. Subject to the terms hereof,
                  Revolving Loans that are repaid prior to the Final Maturity
                  Date may be reborrowed.

                           (ii) The failure of any Revolving Lender to make a
                  Revolving Advance to be made by it as part of any Revolving
                  Loan shall not relieve, in and of itself, any other Revolving
                  Lender of its obligation hereunder to make its Revolving
                  Advance on the date of such Revolving Loan, but no Revolving
                  Lender shall be responsible for the failure of any other
                  Revolving Lender to make the Revolving Advance to be made by
                  such other Revolving Lender on the date of such Revolving
                  Loan.

                  (b) Revolving Loan Notes

                           (i) All Revolving Advances made by each Revolving
                  Lender shall be evidenced by a Revolving Loan Note of the
                  Borrower in the form of Exhibit B hereto (each a "Revolving
                  Loan Note" and, collectively, the "Revolving Loan Notes"),
                  dated the Closing Date, payable to such Lender for the account
                  of its Applicable Lending Office in an aggregate principal
                  amount equal to its Pro Rata Share of the Maximum Revolving
                  Loan Amount and otherwise duly completed. Each Revolving Loan
                  Note shall (A) represent the Borrower's obligation to pay the
                  aggregate unpaid principal amount of all outstanding Revolving
                  Advances made by such Lender, (B) be stated to mature on the
                  Final Maturity Date, (C) bear interest for the period from the
                  date thereof until paid in full on the unpaid principal amount
                  thereof from time to time outstanding at the applicable
                  interest rate per annum provided in, and payable as specified
                  in, this Agreement, and (D) be entitled to the benefits of
                  this Agreement and the Security Documents.

                           (ii) Each Revolving Lender is hereby authorized to
                  record the date and amount of each Revolving Advance made by
                  it and the Type thereof and the date and amount of each
                  payment and prepayment of principal made with respect thereto,
                  and all Conversions of such Advances pursuant to Section 2.04,
                  and prior to any Transfer of its Revolving Loan Note may
                  annotate on the schedule forming a part thereof appropriate
                  notations to evidence the foregoing information with respect
                  to each such Revolving Advance then outstanding; provided,
                  that, failure by such Revolving Lender to make any such
                  annotation or any error therein shall

                                       37
<PAGE>   44

                  not affect the obligations of the Borrower hereunder or under
                  such Revolving Loan Note in respect of such Revolving Advances
                  evidenced thereby. Each Revolving Lender is hereby irrevocably
                  authorized by the Borrower to endorse its Revolving Loan Note
                  and to attach to and make a part of its Revolving Loan Note a
                  continuation of such schedule as and when required.

                  (c) Types of Revolving Advances. All or any portion of any
Revolving Advances shall be either Base Rate Advances or LIBO Rate Advances, and
may be Converted or continued from time to time pursuant to Section 2.04.

                  (d) Use of Proceeds of Revolving Loans. The Borrower shall use
the proceeds of each Revolving Loan solely to pay (i) Operating Costs
contemplated by the then current Operating Budget (as administered pursuant to
Section 5.11 hereof) to the extent that funds in the Operating Account are
insufficient for such purpose, (ii) on the Closing Date, the purchase price of
certain inventories, supplies and spare parts (including coal or other fuel
inventories), pro-rated expenses (including certain Taxes), all as agreed among
the Borrower and the Arrangers on or prior to the Closing Date. In no event
shall the proceeds of Revolving Loans be used to (i) pay Acquisition Costs
(except to the extent referenced above), (ii) pay Debt Service, or (iii) make
Distributions.

                  (e)      Repayment

                           (i) The Borrower shall repay the principal of all
                  outstanding Revolving Loans in full on the Final Maturity
                  Date.

                           (ii) Notwithstanding anything to the contrary in this
                  Agreement, for so long as the Revolving Loan Commitments are
                  in effect, the Borrower agrees to repay the entire principal
                  amount of Revolving Loans outstanding from time to time such
                  that, for a period of ten (10) consecutive days on a rolling
                  twelve (12) months basis during each calendar year in which
                  either an Acquisition Loan Commitment or a Revolving Loan
                  Commitment is in effect or any Loan remains outstanding and
                  unpaid, there shall be no Revolving Loans outstanding under
                  this Agreement.

                           (iii) Notwithstanding anything to the contrary in
                  this Agreement, for so long as the Revolving Loan Commitments
                  are in effect, the Borrower agrees to repay the principal
                  amount of Revolving Loans outstanding from time to time such
                  that on each Distribution Date (as defined in the Deposit
                  Account Agreement) the aggregate principal amount of Revolving
                  Loans outstanding plus the aggregate Letter of Credit Exposure
                  shall be equal to or less than $25,000,000.

                  (a) Acquisition Loans. The Acquisition Loan shall be made on
notice from the Borrower to the Administrative Agent, given not later than 10:00
a.m. (New York City time) (x) on the third (3rd) Business Day prior to the
proposed Closing Date, if such Acquisition Loan is to be a LIBO Rate Loan, or
(y) on the Business Day prior to the proposed Closing Date, if such Acquisition
Loan is to be a Base Rate Loan. Such notice by the Borrower (a "Notice of
Acquisition Borrowing") shall be irrevocable and shall be in writing in
substantially the form of Exhibit C, specifying therein (i) the proposed Closing
Date, (ii) the aggregate amount of the Acquisition Loan to be made on such date,
(iii) the requested Type of Acquisition Loan, (iv) the specific Acquisition

Acquisition Lender shall, before 10:00 a.m. (New York City time) on the Closing
Date, make available to the Administrative Agent, for the account of its
Applicable Lending Office, in immediately available funds, the amount of such
Acquisition Lender's Acquisition Loan Advance. Subject to the Administrative
Agent's receipt of such funds and fulfillment of the applicable conditions set
forth in Article III for such Acquisition Loans, the Administrative Agent will
make such funds available to the Borrower at its account with the Administrative
Agent at its Applicable Lending Office or at such other account designated by
the Borrower in the Notice of Acquisition Borrowing.

                  (b) Revolving Loans. Each Revolving Loan shall be made on
notice from the Borrower to the Administrative Agent, given not later than 10:00
a.m. (New York City time) (x) on the third (3rd) Business Day prior to the
proposed Revolving Loan Funding Date, if such Revolving Loan is to be a LIBO
Rate Loan, or (y) on the Business Day prior to the proposed Revolving Loan
Funding Date, if such Revolving Loan is to be a Base Rate Loan. Such notice by
the Borrower (a "Notice of Revolving Borrowing"), shall be irrevocable and shall

proposed Revolving Loan Funding Date, (ii) the requested aggregate amount of the
Revolving Loan, (iii) any specific payment instructions regarding the
disbursement of the proceeds of such Revolving Loan, (iv) the requested Type of
Revolving Loan and (v) with respect to a LIBO Rate Loan, the initial Interest

shall, no later than 10:00 a.m. (New York City time) on the applicable Revolving
Loan Funding Date, make available to the Administrative Agent, for the account

                  (c) Participations. If the Administrative Agent has not
received from the Borrower the payment required by Section 2.16(g) by 12:30 p.m.
(New York City time), on the Business Day immediately following the date on
which the Issuing Bank has notified the Borrower and the Administrative Agent
that payment of a draft presented under any DLC Letter of Credit or any
Operational Letter of Credit will be made, as provided in Section 2.16(g) or
2.17(g), as applicable, the Administrative Agent will promptly notify the
Issuing Bank and each Revolving Lender of the DLC Letter of Credit Disbursement
or the Operational Letter of Credit Disbursement, as the case may be, and, in
the case of each Revolving Lender, its Pro Rata Share (based on such Revolving
Lender's Revolving Loan Commitment) of the DLC Letter of Credit Disbursement or
the Operational Letter of Credit Disbursement, as the case may be. Not later
than 10:00 a.m. (New York City time) on the next Business Day, each Revolving
Lender shall, irrespective of the existence of any Default or Event of Default
or failure of any other applicable condition precedent, make available its Pro
Rata Share of the DLC Letter of Credit Disbursement or the Operational Letter of
Credit Disbursement, as the case may be, in Federal or other funds immediately
available in New York, New York, to the Administrative Agent at its address set
forth in Section 9.01. Any such funding of a DLC Letter of Credit Disbursement
or the Operational Letter of Credit Disbursement, as the case may be, by the
Revolving Lenders shall be considered as Revolving Advances made to the
Borrower. Any Revolving Loans made pursuant to this Section 2.03(c) shall be
made as Base Rate Loans and the Administrative Agent will promptly make such
funds available to the Issuing Bank. In the event that any Revolving Advance
cannot for any reason be made on the date otherwise required above (including,
without limitation, as a result of the commencement of a proceeding under the
Bankruptcy Code with respect to the Borrower), then each Revolving Lender shall
forthwith purchase (as of the date such Revolving Advance would otherwise have
occurred) from the Issuing Bank such Revolving Lender's Pro Rata Share of the
DLC Letter of Credit Disbursement or the Operational Letter of Credit
Disbursement, as the case may be.

                  Section 2.04  Election of Interest Rates.

                  (a) So long as no Default or Event of Default shall have
occurred and be continuing (and notwithstanding the existence of any Default or
Event of Default with respect to a Conversion from a LIBO Rate Loan to a Base
Rate Loan), the Borrower may from time to time elect to Convert any Loan of any
Type to a Loan of the same or any other Type on the following terms and subject
to the following conditions:

                           (i) Each such Conversion shall be made as to all or a
                  portion of the outstanding Loans, on notice given not later
                  than 10:00 a.m. (New York City time) on the third (3rd)
                  Business Day prior to the date of the proposed Conversion, in
                  the case of any such Conversion into LIBO Rate Loans, or on
                  the Business Day prior to the date of the proposed Conversion,
                  in the case of any such Conversion into Base Rate Loans, by
                  the Borrower to the Administrative Agent, who shall give each
                  applicable Lender prompt notice thereof. Each such notice of
                  Conversion (a "Notice of Conversion") shall be in writing in
                  substantially the form of Exhibit E

                                       40
<PAGE>   47

                  hereto, specifying therein the requested (A) date of such
                  Conversion, (B) Type of, and, with respect to LIBO Rate Loans,
                  Interest Period applicable to, the Loans proposed to be
                  Converted, (C) Type of Loans to which such Loans are proposed
                  to be Converted, (D) in the case of a Conversion to LIBO Rate
                  Loans, initial Interest Period to be applicable to the Loans
                  resulting from such Conversion and (E) aggregate amount of
                  Loans proposed to be Converted. If the Notice of Conversion
                  applies only to a portion of the aggregate principal amount of
                  the Loans, (X) such portion shall be allocated ratably among
                  the applicable Lenders and (Y) both the portion to which the
                  Notice of Conversion applies and the remaining portion to
                  which it does not apply, shall be sufficient to meet the
                  minimum amounts specified in Section 2.06(f). In the case of a
                  proposed Conversion into LIBO Rate Loans, the Administrative
                  Agent shall, within one Business Day of receiving the Notice
                  of Conversion from the Borrower, notify each applicable Lender
                  of the interest rate to be applicable to such LIBO Rate Loan
                  resulting from such Conversion pursuant to this Section 2.04.

                           (ii) LIBO Rate Loans may not be Converted on a date
                  other than the last day of the Interest Period then applicable
                  thereto.

                           (iii) No Conversion may be requested by the Borrower
                  hereunder unless made in compliance with the definition of
                  "Interest Period," Section 2.06 and Section 2.10.

                           (iv) Any selection by the Borrower of a longer or
                  shorter Interest Period to be applicable to any LIBO Rate Loan
                  shall be deemed a Conversion pursuant to this Section 2.04,
                  shall be governed by the terms and conditions hereof and shall
                  be notified to the Administrative Agent as herein provided. In
                  the event the Borrower shall fail to elect an Interest Period
                  in respect of any LIBO Rate Loan prior to the expiration of
                  the then current Interest Period in respect of such LIBO Rate
                  Loan, then such LIBO Rate Loan shall automatically be
                  Converted into a Base Rate Loan in accordance with this
                  Section 2.04.

                  (b) Each Notice of Borrowing and Notice of Conversion shall be
irrevocable and binding on the Borrower. The Borrower shall indemnify each
Lender against any loss, cost or expense incurred by such Lender as a result of
any failure to fulfill, on or before the proposed date specified in such Notice
of Borrowing or Notice of Conversion, as the case may be, the applicable
conditions set forth in this Article II or Article III, including, without
limitation, any loss, cost or expense incurred by reason of the liquidation or
re-employment of deposits or other funds acquired by such Lender to fund or
Convert such Loan.

                  (c) So long as any Interest Hedge Contract is in effect with
respect to any Loans, the Borrower shall maintain as LIBO Rate Loans having
Interest Periods corresponding to the payment dates under such Interest Hedge
Contract an aggregate

                                       41
<PAGE>   48

amount of Loans at least equal to the notional amount then in effect under such
Interest Hedge Contract, except to the extent the Borrower would be prevented
from complying with this Section 2.04(c) by operation of Section 2.10.

                  Section 2.05      Fees.

                  (a) Commitment Fee. The Borrower shall pay to the
Administrative Agent, quarterly in arrears on each Quarterly Payment Date, for
the account of each Lender, commitment fees (the "Commitment Fees") of (i)
0.375% per annum on the average daily unutilized amount of each Acquisition
Lender's Acquisition Loan Commitment during the period from the Closing Date
until, and including, the termination of all Acquisition Loan Commitments
pursuant to the terms of this Agreement, and (ii) 0.375% per annum on the
average daily unutilized amount of each Revolving Lender's Revolving Loan
Commitment during the period from the Closing Date until, and including, the
Final Maturity Date. For purposes of this Section 2.05(a), the "unutilized
amount" of a Revolving Lender's Revolving Loan Commitment on any date shall mean
the amount of such Revolving Lender's Revolving Loan Commitment on such date,
minus the sum of (X) its outstanding Revolving Advances on such date and (Y) its
Letter of Credit Exposure on such date.

                  (b) Agency Fee. The Borrower shall pay the Agency Fee to the
Administrative Agent, for the Administrative Agent's own account, in accordance
with the terms of the Administrative Agent Fee Side Letter.

                  (c) Letter of Credit Fees. The Borrower shall pay (i) the DLC
Letter of Credit Fees to the applicable Persons in accordance with the terms set
forth in Section 2.16 below and (ii) the Operational Letter of Credit Fees to
the applicable Persons in accordance with the terms set forth in Section 2.17
below.

                  (d) Other Fees. The Borrower shall pay all Fees not
specifically contemplated by clauses (a) and (b) of this Section 2.05 to the
appropriate Persons in the amounts and at such times as set forth in the Fee
Side Letters and any other applicable Financing Document.

                  Section 2.06 Interest. The Borrower shall pay interest on the
unpaid principal amount of each Advance made by each Lender from the date of
such Advance until such principal amount shall be paid in full, at one of the
following rates per annum:

                  (a) If such Advance is a Base Rate Advance, a rate per annum
equal at all times to the sum of the Base Rate in effect from time to time plus
the Applicable Margin, payable quarterly in arrears on each applicable Interest
Payment Date and on the date that such Base Rate Advance shall be repaid in
full.

                  (b) If such Advance is a LIBO Rate Advance, a rate per annum
equal at all times during each Interest Period for such Advance to the sum of
the LIBO Rate for such Interest Period for such Advance plus the Applicable
Margin, payable on the

                                       42
<PAGE>   49

applicable Interest Payment Date and on the date that such LIBO Rate Advance
shall be repaid in full.

                  (c) If an Event of Default shall have occurred and be
continuing and whether or not so specified in any Note, the Borrower shall pay,
upon receipt of written demand, interest on the entire principal amount of the
Loans to the extent permitted by applicable Requirements of Law, on any overdue
installment of interest and on any other amount due hereunder during such period
at a rate per annum equal at all times to 2.00% plus the LIBO Rate for such
period plus the LIBO Rate Margin for such period, if the Loans are LIBO Rate
Loans or, at a rate per annum equal to 2.00% plus the Base Rate for such period
plus the Base Rate Margin for such period, if the Loans are Base Rate Loans,
which increased interest shall be payable on the last Business Day of each month
during the continuation of such Event of Default.

                  (d) If the Administrative Agent is unable at any time to
determine the LIBO Rate for LIBO Rate Loans, if the Administrative Agent shall
determine that the LIBO Rate does not reflect the cost of funding LIBO Rate
Loans or if any Lender shall have determined that such Lender is unable to
acquire funding in a reasonable manner so as to make available LIBO Rate Loans
in the amount and for the Interest Period requested, the right to maintain the
Loans as LIBO Rate Loans shall be suspended at the end of the then current
Interest Period and all Loans shall be maintained as Base Rate Loans until the
Administrative Agent shall notify the Borrower and the Lenders that the
circumstances causing such suspension no longer exist.

                  (e) At no time shall more than six (6) different Interest
Periods be in effect as to outstanding LIBO Rate Loans hereunder.

                  (f) Each LIBO Rate Loan shall be in a minimum aggregate
principal amount of $1,000,000.

                  Section 2.07  Mandatory Prepayments.

                  (a) Subject to Section 2.07(c) hereof, all Extraordinary
Proceeds received by the Administrative Agent or the Borrower shall be applied
to prepay the then outstanding Acquisition Loans in accordance with the Deposit
Account Agreement, and after all Acquisition Loans have been prepaid in full,
applied to prepay then outstanding Revolving Loans in accordance with the
Deposit Account Agreement. Any prepayment of Revolving Loans required by this
Section 2.07(a) shall automatically reduce pro rata the amount of Revolving Loan
Commitments by an amount equal to the prepayment so required. Contemporaneously
with any reduction of Revolving Commitments required by this Section 2.07(a),
the Borrower shall cash collateralize with the Administrative Agent the
difference between (y) any Letter of Credit Exposure existing at such time, less
(z) the aggregate amount of the Revolving Loan Commitments existing after the
application of the terms of this Section 2.07(a), until such time as such Letter
of Credit Exposure no longer exists. Nothing in this Section 2.07(a) shall be
deemed to imply that any of the activities or actions described in clauses (ii)
or (iii) of the definition of

                                       43
<PAGE>   50

Extraordinary Proceeds are permitted under this Agreement other than as
specifically set forth in this Agreement.

                  (b) In addition to the foregoing, until the Final Maturity
Date, the Borrower shall prepay the Acquisition Loans on each Quarterly Payment
Date, in the amounts set forth in and as contemplated by the Deposit Account
Agreement.

                  (c) Notwithstanding Section 2.07(a) hereof, to the extent that
prepayment of Loans with Extraordinary Proceeds would require the Borrower to
pay Funding Breakage Costs in accordance with Section 2.09(c) below, such
Extraordinary Proceeds shall be deposited in the Extraordinary Proceeds Account
in accordance with the Deposit Account Agreement until such date(s) as the
application of such proceeds can be applied to the prepayment of Loans without
incurring such Funding Breakage Costs.

                  (d) In the event the interest rate on any Acquisition Loan is
fixed or capped pursuant to an Interest Hedge Contract, the Borrower shall pay
all Settlement Amounts required under such Interest Hedge Contract in connection
with any mandatory prepayment of such Loan.

                  Section 2.08 Voluntary Prepayment; Termination of Commitments;
Revolving Commitment Reductions. (a) The Borrower may, upon at least five
Business Days' prior written notice to the Administrative Agent stating the
proposed date and aggregate principal amount of the prepayment, and if such
notice is given the Borrower shall, prepay the outstanding principal amounts of
the Loans in whole or ratably in part in the amount set forth in such notice,
together with accrued interest to the date of such prepayment on the principal
amount prepaid; provided, that (i) each partial prepayment shall be in a minimum
aggregate principal amount of $1,000,000 or whole multiples thereof (or, if
less, the entire balance then remaining), (ii) concurrently with such payment,
the Borrower shall pay all applicable Funding Breakage Costs in accordance with
Section 2.09(c) below and, (iii) to the extent applicable, the Borrower shall
have reduced the aggregate notional amounts of any Interest Hedge Contracts
existing on such prepayment date such that such aggregate notional amounts do
not exceed the aggregate principal amount of outstanding Loans on such date and
shall have paid any Settlement Amounts incurred in connection therewith. Each
such voluntary prepayment shall otherwise be without penalty or premium.

                  (b) The Revolving Loan Commitments shall be automatically
terminated on the expiration of the Revolving Loan Availability Period.

                  (c) Upon at least six Business Days' prior irrevocable written
or telecopy notice to the Administrative Agent, the Borrower may at any time in
whole permanently terminate, or from time to time in part permanently reduce,
the Revolving Loan Commitments; provided, that, (i) each partial reduction of
the Revolving Loan Commitments shall be in an aggregate principal amount which
is equal to $1,000,000 or an integral multiple thereof; (ii) concurrently with
such payment, the Borrower shall pay all applicable Funding Breakage Costs in
accordance with Section 2.09(c) below, (iii) to the extent applicable, the
Borrower shall have reduced the aggregate notional amounts of

                                       44
<PAGE>   51

any Interest Hedge Contracts existing on such prepayment date such that such
aggregate notional amounts do not exceed the aggregate principal amount of
outstanding Loans on such date and shall have paid any Settlement Amounts
incurred in connection therewith, and (iv) concurrently with any such reduction
in the Revolving Loan Commitments, the Borrower shall deposit with the
Administrative Agent cash collateral in an amount equal to the difference
between (y) any Letter of Credit Exposure existing at such time, less (z) the
aggregate amount of the Revolving Loan Commitments existing after the
effectiveness of such reduction, until such time as such Letter of Credit
Exposure no longer exists.

                  (d) Each reduction in the Revolving Loan Commitments shall be
made ratably among the Revolving Lenders in accordance with their respective
Revolving Loan Commitments. The Borrower shall pay to the Administrative Agent
for the account of the Revolving Lenders, on the date of each termination or
reduction of the Revolving Loan Commitments, all accrued but unpaid Commitment
Fees on the amount of the Revolving Loan Commitments so terminated or reduced
accrued to the date of such termination or reduction.

                  Section 2.09  Increased Costs; Capital Adequacy;
Funding Breakage Costs.

                  (a) If, due to either (i) the enactment, promulgation or any
change (including any change by way of imposition of reserve requirements in the
case of LIBO Rate Loans) in any Requirement of Law or in the interpretation or
administration of any Requirement of Law by any Governmental Authority charged
with the interpretation or administration thereof on or after the date hereof or
(ii) the compliance with any guideline or request from any such Governmental
Authority (whether or not having the force of law) imposed on or after the date
hereof, there shall be any increase in the cost to any Lender of agreeing to
make or making, funding or maintaining LIBO Rate Loans, then such Lender shall
deliver to the Borrower and the Administrative Agent a certificate as to the
amount of such increased cost setting forth in reasonable detail the basis for
calculation thereof as soon as practicable but in no event later than one
hundred twenty (120) days after such Lender has actual knowledge of the event
(the date that is 120 days from the date any Lender obtains actual knowledge of
any such event being referred to herein as the "Notice Date"). Within fifteen
(15) days after delivery of such certificate, the Borrower shall pay to such
Lender the amount shown as due on the certificate; provided, that the Borrower
shall not be obligated to compensate that Lender for the amount of such
increased cost incurred during the period of time from the Notice Date to the
date of actual delivery of the certificate. A certificate as to the amount of
such increased cost showing the basis therefor and the calculation thereof, in
reasonable detail, submitted to the Borrower and the Administrative Agent by
such Lender, shall be conclusive and binding for all purposes, absent manifest
error.

                  (b) If any Lender determines that compliance with any
Requirement of Law or regulation or with any guideline or request from any
central bank or other governmental authority (whether or not having the force of
law) has the effect of reducing the rate of return on the capital of such Lender
or any corporation controlling such Lender

                                       45
<PAGE>   52

as a consequence of, or with reference to, this Agreement, any Letter of Credit
or such Lender's Commitments, or its making or maintaining Loans below the rate
which the Lender or any other corporation would have achieved but for such
compliance (taking into account the policies of such Lender or corporation with
regard to capital), then such Lender shall deliver to the Borrower and the
Administrative Agent a certificate setting forth in reasonable detail the amount
being charged by such Lender and the basis for the determination of such amount
as soon as practicable but in no event later than one hundred twenty (120) days
after the Notice Date in respect thereof. Within fifteen (15) days after
delivery of such certificate, the Borrower shall pay to such Lender the amount
shown as due on the certificate; provided, that the Borrower shall not be
obligated to compensate that Lender for the amount of such charge incurred with
respect to a period of time from the Notice Date to the date of actual delivery
of the certificate. A certificate as to such amounts, submitted to the Borrower
and the Administrative Agent by such Lender, shall be conclusive and binding for
all purposes, absent manifest error.

                  (c) If (i) any payment of principal of any LIBO Rate Loan is
made other than on the last day of the Interest Period for such Loan, as a
result of a payment or prepayment of such Loan or acceleration of the maturity
of the Notes or for any other reason or (ii) upon any failure to prepay a LIBO
Rate Loan after notice of prepayment has been given or any failure to borrow a
LIBO Rate Loan, continue a LIBO Rate Loan or convert a LIBO Rate Loan after
notice of borrowing, continuation or conversion has been given, then the
Borrower shall, upon demand by any Lender (with a copy of such demand to the
Administrative Agent), pay to the Administrative Agent for the account of such
Lender any amounts required to compensate such Lender for any additional losses,
costs or expenses which it may reasonably incur as a result of such payment,
including, without limitation, any loss, cost or expense incurred by reason of
the liquidation or reemployment of deposits or other funds acquired by any
Lender to fund or maintain such Loan. The foregoing amounts payable by the
Borrower under this Section 2.09(c) shall be referred to herein as "Funding
Breakage Costs".

                  (d) Each Lender agrees to notify the Borrower and the
Administrative Agent of any circumstances that would cause the Borrower to pay
additional amounts pursuant to subsections (a) and (b) of this Section 2.09 on
or prior to the Notice Date; provided, that, the failure to give such notice
shall not affect the Borrower's obligation to pay any such additional amounts
accrued prior to the Notice Date or after delivery of such notice.

                  Section 2.10 Illegality. If the enactment, promulgation or any
change in or in the interpretation of any Requirement of Law after the Closing
Date shall make it unlawful, or any central bank or other Governmental Authority
to which any Lender is subject shall assert that it is unlawful, for any Lender
or its LIBO Lending Office to perform its obligations hereunder to make LIBO
Rate Loans or to continue to fund or maintain LIBO Rate Loans hereunder, then,
on notice thereof and demand therefor by such Lender to the Borrower through the
Administrative Agent, the obligation of such Lender to make or maintain LIBO
Rate Loans shall be suspended until such Lender shall

                                       46
<PAGE>   53

notify the Administrative Agent that the circumstances causing such suspension
no longer exist and such Lender shall maintain all of its Loans as Base Rate
Loans.

                  Section 2.11      Payments and Computations.

                  (a) The Borrower shall make each payment hereunder and under
the Notes not later than 12:00 Noon New York City time on the day when due in
Dollars to the Administrative Agent at its Applicable Lending Office in
immediately available funds. The Administrative Agent shall promptly thereafter
cause to be distributed like funds relating to the payment of principal,
interest or Fees (other than amounts payable to the Administrative Agent for
Agency Fees and expenses or to reimburse the Administrative Agent pursuant to
Section 2.12) ratably to the Lenders for the account of their respective
Applicable Lending Offices, and like funds relating to the payment of any other
amount payable to any Lender to such Lender for the account of its Applicable
Lending Office, in each case to be distributed and applied in accordance with
the terms of subsection (b) of this Section 2.11.

                  (b) All payments received by the Administrative Agent in
respect of the Loans whether received under Section 2.11(a), in connection with
any sale or other realization upon the Collateral or otherwise shall be
distributed and applied in the order and in the amounts set forth in the Deposit
Account Agreement.

                  (c) The Borrower hereby authorizes each Lender, if and to the
extent that the Borrower has failed to pay amounts due hereunder or under any
Financing Document and as a result payment owed to such Lender is not made when
due hereunder or under any other Financing Document, to charge from time to time
against any or all of the Borrower's accounts with such Lender any amount so
due. Each Lender receiving any payment as a result of charging any such account
shall promptly notify the Administrative Agent thereof and make such
arrangements as the Administrative Agent shall request to share the benefit
thereof in accordance with Section 2.13 and the Deposit Account Agreement.

                  (d) All computations of (i) interest hereunder based on the
LIBO Rate or the Federal Funds Rate and (ii) Commitment Fees, shall be made by
the Administrative Agent on the basis of a year of 360 days and all computations
of interest hereunder based on the Base Rate shall be made by the Administrative
Agent on the basis of a year of 365 or 366 days, as the case may be, in each
case for the actual number of days (including the first day but excluding the
last day) occurring in the period for which such interest or fees are payable.
Each determination by the Administrative Agent of an interest rate hereunder
shall be conclusive and binding for all purposes, absent manifest error.

                  (e) Except as contemplated by the definition of "Interest
Period" for LIBO Rate Loans, whenever any payment hereunder or under any
Financing Document shall be stated to be due on a day other than a Business Day,
such payment shall be made on the first Business Day preceding such required
payment date.

                                       47
<PAGE>   54

                  (f) Unless the Administrative Agent shall have received notice
from the Borrower prior to the date on which any payment is due to a Secured
Party hereunder that the Borrower will not make such payment in full, the
Administrative Agent may, but shall not be required to, assume that the Borrower
has made such payment in full to the Administrative Agent on such date and the
Administrative Agent may, in reliance upon such assumption, but shall not be
required to, cause to be distributed to each Secured Party on such due date an
amount equal to the amount then due such Secured Party. If and to the extent the
Borrower shall not have so made such payment in full to the Administrative
Agent, each Lender shall repay to the Administrative Agent forthwith on demand
such amount distributed to such Lender together with interest thereon, for each
day from the date such amount is distributed to such Lender until the date such
Lender repays such amount to the Administrative Agent, (i) at the Federal Funds
Rate for the three Business Days following demand by the Administrative Agent
and (ii) the Federal Funds Rate plus 1% for each day thereafter.

                  (g) Unless the Administrative Agent shall have received notice
from a Secured Party prior to the date of any Borrowing, or prior to the time of
any required payment by such Secured Party in respect of a DLC Letter of Credit
Disbursement or an Operational Letter of Credit Disbursement, as the case may
be, that such Secured Party will not make available to the Administrative Agent
such Secured Party's portion of such borrowing or payment, the Administrative
Agent may assume that such Secured Party has made such portion available to the
Administrative Agent on the date of such borrowing or payment in accordance with
Section 2.03 and the Administrative Agent may, in reliance upon such assumption,
make available to the Borrower on such date a corresponding amount. If and to
the extent that such Secured Party shall not have made such portion available to
the Administrative Agent, such Secured Party and the Borrower severally agree to
repay to the Administrative Agent forthwith on demand such corresponding amount
together with interest thereon, for each day from the date such amount is made
available to the Borrower or the Issuing Bank (or, if the Administrative Agent
and the Issuing Bank are the same person, from the date of such payment in
respect of a DLC Letter of Credit Disbursement or an Operational Letter of
Credit Disbursement, as the case may be), as applicable, until the date such
amount is repaid to the Administrative Agent at (i) in the case of the Borrower,
the interest rate applicable thereto pursuant to Section 2.06 or 2.16(g), as
applicable, and (ii) in the case of such Secured Party, (y) the Federal Funds
Rate for the three Business Days following demand by the Administrative Agent
and (z) the Federal Funds Rate plus 1% for each day thereafter.

                  Section 2.12  Taxes.

                  (a) Any and all payments by the Borrower hereunder or under
the Notes to or for the benefit of any Secured Party shall be made free and
clear of and without deduction for any and all present or future taxes
(including, without limitation, income, gross receipts, franchise, sales, use,
personal property, license, stamp, documentary, recording, privilege or other
excise tax), levies, imposts, deductions, charges or withholdings, together with
any penalties, fines or interest thereon, and all liabilities with respect
thereto, imposed by any Governmental Authority, excluding,

                                       48
<PAGE>   55

income or franchise taxes measured by net income imposed under the laws of the
United States or any state, or any political subdivision thereof, in which each
such Secured Party is organized, or, solely in the case of each such Lender, in
which the Applicable Lending Office or the principal office of such Lender is
located (all such excluded net income taxes and franchise taxes hereinafter
referred to as "Income Taxes" and all nonexcluded taxes, levies, imposts,
deductions, charges, withholdings and liabilities being hereinafter referred to
as "Taxes"). If the Borrower shall be required by law to deduct any Taxes from
or in respect of any sum payable hereunder or under any Note to or for the
benefit of any Secured Party Lender, (i) the sum payable shall be increased as
may be necessary so that after making all required deductions of Taxes
(including deductions of Taxes applicable to additional sums payable under this
Section 2.12) such Secured Party receives an amount equal to the sum it would
have received had no such deductions been made, (ii) the Borrower shall make
such deductions and (iii) the Borrower shall pay the full amount so deducted to
the relevant taxation authority or other authority in accordance with applicable
Requirement of Law.

                  (b) In addition, without limiting the generality of this
Section 2.12, the Borrower agrees to pay any present or future stamp,
documentary, recording, privilege, intangible or similar taxes or any other
excise or property taxes, charges or similar levies that arise at any time or
from time to time (i) from any payment made under any and all Financing
Documents, (ii) from the transfer of the rights of any Secured Party under any
Financing Documents to any other Secured Party or (iii) from the execution or
delivery by the Borrower or any Credit Party of, or from the filing or recording
or maintenance of, or otherwise with respect to, any and all Financing
Documents.

                  (c) The Borrower will indemnify each Secured Party for the
full amount of all Taxes (excluding any Income Taxes imposed by any jurisdiction
on amounts payable under this Section 2.12) paid by, or imposed or asserted
against, such Secured Party or any Collateral, as the case may be, and any
liability (including penalties, interest and expenses) arising therefrom or with
respect thereto, which Taxes are imposed or asserted in any manner resulting
from or relating to or arising from the execution, delivery or performance of
the Financing Documents, the Transaction Documents or the transactions
contemplated thereby, whether or not such Taxes were correctly or legally
asserted by the relevant Governmental Authority. A certificate as to the amount
of such payment or liability prepared by such Secured Party, absent manifest
error, shall be final, conclusive and binding for all purposes. Payment of this
indemnification shall be made within 30 days from the date such Secured Party
makes written demand therefor. With respect to any such Taxes for which any
Secured Party is entitled to indemnification pursuant to this paragraph, such
Secured Party agrees to cooperate with the Borrower and to provide to it such
information as may be reasonably requested by it for the purpose of establishing
the entitlement of the Borrower to a refund or credit of all or any portion of
such Taxes; provided, that, no Secured Party shall be required to provide to the
Borrower (a) copies of any of its tax or information returns or (b) any other
information which would prejudice the interests of such Secured Party (as
reasonably determined by such

                                       49
<PAGE>   56

Secured Party, in its good faith judgment) or which it reasonably deems to be of
a confidential nature.

                  (d) As soon as practicable after the date of any payment of
Taxes by the Borrower or other authority to the relevant Governmental Authority,
the Borrower will deliver to the Administrative Agent (for delivery to each
Lender) at its address referred to on its signature page hereto, the original or
a certified copy of a receipt issued by such Governmental Authority evidencing
payment thereof and identifying the Taxes paid. If such receipt does not
identify such Taxes paid, and no procedure exists for identifying such Taxes
paid, the Borrower shall concurrently furnish to the Administrative Agent a
certificate, signed by a Responsible Officer of the Borrower providing such
identification. The Borrower shall compensate each Secured Party, as the case
may be, for all reasonable losses and expenses sustained by such Secured Party,
as a result of any failure by the Borrower to so furnish such original or copy
of such receipt or such certificate.

                  (e) If any Secured Party is not organized and existing under
the laws of the United States of America or any political subdivision thereof or
therein (a "Foreign Secured Party"), to the extent entitled to do so under
Applicable Law, such Secured Party shall furnish to the Borrower, on the Closing
Date (or on the date on which such Foreign Secured Party first becomes a Secured
Party pursuant to Section 9.06) a duly executed certificate to the effect that
such Foreign Secured Party is entitled to receive all amounts payable under the
Financing Documents without deduction or withholding (or at a reduced rate of
deduction or withholding) on account of Taxes imposed by the United States of
America (i) pursuant to the terms of an applicable tax treaty in effect with the
United States of America (in which case such certificate shall be accompanied by
two executed copies of IRS Form W-8BEN), or (ii) under Code Section 1441(c) (in
which case such certificate shall be accompanied by two executed copies of IRS
Form W-8ECI) (such forms being the "Prescribed Forms"). If requested by the
Borrower from time to time after the Closing Date (upon the obsolescence of any
previously delivered form or otherwise), or if a new form is required by any
applicable Requirement of Law, a Foreign Secured Party shall, to the extent
required thereto under any applicable Requirement of Law, provide to the
Borrower new Prescribed Forms, in each case duly executed and completed by such
Foreign Secured Party. The Borrower shall not be required to indemnify any
Foreign Secured Party or pay any additional amounts to any Foreign Secured Party
pursuant to Sections 2.12(a), 2.12(c) or 2.12(d) to the extent that the
obligation to indemnify such Foreign Secured Party or pay such additional
amounts would not have arisen but for the failure by such Foreign Secured Party
to comply with applicable certification, information or other documentation
requirements concerning the nationality, residency, identity or connection with
the United States of such Foreign Secured Party if such compliance is required
by statute or regulation of the United States as a precondition to relief or
exemption from such amounts payable under, or for which indemnification is given
pursuant to, Sections 2.12(a), (c) or (d); provided, that, the Borrower shall be
required to indemnify each Foreign Secured Party to the extent that (A) any such
payment or indemnification is attributable to an enactment, promulgation or any
change in or interpretation of any Requirement of Law occurring after the date
hereof and

                                       50
<PAGE>   57

(B) such deductions, withholding, payments or liabilities accrue after the date
on which such Secured Party timely furnishes to the Borrower all Prescribed
Forms required to be furnished by this Section 2.12(e) with respect to such
enactment, promulgation or any change in or interpretation of any Requirement of
Law.

                  (f) Without prejudice to the survival of any other agreement
of the Borrower hereunder, the agreements and obligations of the Borrower
contained in this Section 2.12 shall survive the payment in full of principal
and interest on the Loans hereunder and under the Notes.

                  Section 2.13 Sharing of Payments. If any Lender shall obtain
any payment (whether voluntary, involuntary, through the exercise of any right
of set-off or otherwise) on account of a Loan made by it in excess of its Pro
Rata Share of payments on account of such Loan obtained by all the Lenders, such
Lender shall forthwith purchase from the other Lenders such participations in
the Loan made by it as shall be necessary to cause such purchasing Lender to
share the excess payment ratably with each of them; provided, that, if all or
any portion of such excess payment is thereafter recovered from such purchasing
Lender, such purchase from each Lender shall be rescinded and each such Lender
shall repay to the purchasing Lender the purchase price to the extent of such
recovery together with an amount equal to such Lender's Pro Rata Share
(according to the proportion of (i) the amount of such Lender's required
repayment to (ii) the total amount so recovered from the purchasing Lender) of
any interest or other amount paid or payable by the purchasing Lender in respect
to the total amount so recovered. The Borrower agrees that any Lender so
purchasing a participation from another Lender pursuant to this Section 2.13
may, to the fullest extent permitted by law, exercise all its rights of payment
(including the right of set-off) with respect to such participation as fully as
if such Lender were the direct creditor of the Borrower in the amount of such
participation.

                  Section 2.14 Change of Applicable Lending Office. Without
affecting its rights under Section 2.09(a), 2.09(b), 2.10 or 2.12, each of the
Lenders, the Issuing Bank and the Administrative Agent agrees to use reasonable
efforts (consistent with its internal policy and legal and regulatory
restrictions and so long as such efforts would not be disadvantageous to it, in
its sole opinion) to designate a different Applicable Lending Office if such
redesignation would thereafter eliminate or reduce any amounts that the Borrower
is required to pay to any of the Lenders, the Issuing Bank or the Administrative
Agent pursuant to such Sections; provided, that, in determining, in its sole
opinion, whether designating a different Applicable Lending Office would be
disadvantageous to it, the applicable Lender, the Issuing Bank or the
Administrative Agent, as the case may be, shall disregard any direct financial
loss of making such a designation if the Borrower agrees in form and substance
satisfactory to such Lender, the Issuing Bank or the Administrative Agent, as
the case may be, to indemnify and hold such Lender, the Issuing Bank or the
Administrative Agent, as the case may be, harmless from such financial loss and
provided, further, that any out-of-pocket costs and expenses associated with
such efforts shall be paid or reimbursed by the Borrower.

                  Section 2.15 Replacement of Lenders. On each occasion that a
Lender either makes a demand for compensation pursuant to Section 2.06(d),
2.09(a), 2.09(b) or 2.12 in an amount in excess of the amount that the Borrower
would have had to pay pursuant to such Sections if such Lender's Commitments
were held by a Lender with respect to which no such amounts would then be
payable pursuant to any such Section or is unable for a period of two
consecutive months to fund or maintain LIBO Rate Loans pursuant to Section 2.10,
the Borrower may, upon at least ten (10) Business Days' prior written notice to
each of such Lender and the Administrative Agent and upon the payment by the
Borrower of all applicable assignment fees associated therewith (as set forth in
Section 9.06(j) below), in whole permanently replace the Commitment of such
Lender; provided, that, the Borrower shall replace such Commitment with the
commitment of a commercial bank which is reasonably satisfactory to the
Administrative Agent or any other Lender (a "Replacement Lender"). Such
Replacement Lender shall, upon the effective date of replacement, purchase the
Obligations owed to such replaced Lender for the aggregate amount thereof and
shall thereupon for all purposes become a "Lender" hereunder. Such notice from
the Borrower shall specify an effective date for the replacement of such
Lender's Commitment, which date shall not be earlier than the tenth (10th) day
after the day such notice is given. On the effective date of any replacement of
such Lender's Commitment pursuant to this Section 2.15, the Borrower shall pay
to the Administrative Agent for the account of such Lender (i) any Fees or other
amounts due to such Lender to the date of such replacement, (ii) accrued
interest on the principal amount of outstanding Loans held by such Lender to the
date of such replacement and (iii) the amount or amounts payable to such Lender
pursuant to Section 2.09(a), Section 2.09(b) or Section 2.12, as applicable. The
Borrower will be liable to such replaced Lender for costs that such Lender may
sustain or incur pursuant to Section 2.09(c) as a direct consequence of
repayment of such Lender's Loans. Upon the effective date of repayment of any
Lender's Commitment and Obligations pursuant to this Section 2.15, such Lender
shall cease to be a "Lender" hereunder. No such termination of any such Lender's
Commitment and the purchase of such Lender's Loans pursuant to this Section 2.15
shall affect (x) any liability or obligation of the Borrower or any other Lender
to such terminated Lender which accrued on or prior to the date of such
termination or (y) such terminated Lender's rights hereunder in respect of any
such liability or obligation.

                  Section 2.16   DLC Letter of Credit.

                  (a) The Borrower may request the issuance of a DLC Letter of
Credit, for the account of the Borrower, at any time during the DLC Letter of
Credit Availability Period; provided, that, a DLC Letter of Credit shall be
issued only if (and a request by the Borrower for the issuance of a DLC Letter
of Credit shall be deemed a representation and warranty of the Borrower that)
immediately following the issuance of the DLC Letter of Credit, (i) a DLC Letter
of Credit Exposure shall not exceed $10,000,000, and (ii) the sum of the
aggregate Letter of Credit Exposure and the aggregate principal amount of
outstanding Revolving Loans at such time shall not exceed the lesser of (y) the
aggregate

                                       52
<PAGE>   59

Revolving Loan Commitments at such time and (z) the Maximum Revolving Loan
Amount effective as of such time.

                  (b) Each DLC Letter of Credit shall expire at 5:00 p.m., New
York City time, on the last day of the DLC Letter of Credit Availability Period,
unless such DLC Letter of Credit expires by its terms (or is required by Section
2.16(c) to expire) on an earlier date. Each DLC Letter of Credit shall provide
for payments of drawings in Dollars.

                  (c) The issuance of a DLC Letter of Credit shall be made on at
least three Business Days' prior irrevocable written or telecopy application
(such application to be delivered by 10:00 a.m., New York City time) from the
Borrower (or such shorter application period as shall be acceptable to the
Issuing Bank) to the Administrative Agent and the Issuing Bank, specifying the
date of issuance, the date on which such DLC Letter of Credit is to expire
(which shall not be later than the last day of the DLC Letter of Credit
Availability Period and shall be for such period of time as is contemplated by
the form of letter of credit attached hereto as Exhibit M), the amount of such
DLC Letter of Credit, the name and address of the beneficiary of such DLC Letter
of Credit, and such other information as may be necessary or desirable to
complete such DLC Letter of Credit. The Issuing Bank will give the
Administrative Agent prompt notice of the issuance and amount of a DLC Letter of
Credit and the expiration date of such DLC Letter of Credit (and the
Administrative Agent shall give prompt notice thereof to each Revolving Lender).
Any DLC Letter of Credit issued hereunder will be subject to the Uniform Customs
and Practices for Documentary Credits, as in effect from time to time.

                  (d) By the issuance of a DLC Letter of Credit and without any
further action on the part of the Issuing Bank, the Administrative Agent or the
Revolving Lenders in respect thereof, the Issuing Bank hereby grants to each
Revolving Lender, and each Revolving Lender hereby acquires from the Issuing
Bank, a participation in such DLC Letter of Credit equal to such Revolving
Lender's Pro Rata Share (based on such Revolving Lender's Revolving Loan
Commitment) of the aggregate amount available to be drawn under a DLC Letter of
Credit, effective upon the issuance of a DLC Letter of Credit. In consideration
and in furtherance of the foregoing, each Revolving Lender having a Revolving
Loan Commitment hereby absolutely and unconditionally agrees to pay to the
Administrative Agent, on behalf of the Issuing Bank, in accordance with Section
2.03(c), such Revolving Lender's Pro Rata Share (based on such Revolving
Lender's Revolving Loan Commitment) of a DLC Letter of Credit Disbursement made
by the Issuing Bank and not reimbursed by the Borrower when due in accordance
with Section 2.16(g); provided, that, the Revolving Lenders shall not be
obligated to make any such payment with respect to any wrongful DLC Letter of
Credit Disbursement made as a result of the gross negligence or willful
misconduct of the Issuing Bank.

                  (e) Each Revolving Lender acknowledges and agrees that its
obligation to acquire participations pursuant to Section 2.16(d) in respect of a
DLC Letter of Credit is absolute and unconditional and shall not be affected by
any circumstance whatsoever, including the occurrence and continuance of a
Default or Event of Default, and that each such payment shall be made without
any offset, abatement, withholding or

                                       53
<PAGE>   60

reduction whatsoever (subject only to the proviso set forth in the last sentence
of Section 2.16(d)).

                  (f) During the DLC Letter of Credit Availability Period, from
and after the date on which a DLC Letter of Credit is issued, the Borrower shall
pay to the Administrative Agent, on each Quarterly Payment Date in each year and
on the date on which the Revolving Loan Commitments shall be terminated as
provided herein, (i) for the account of the Revolving Lenders, ratably in
proportion to their Revolving Loan Commitments, a fee on the average daily
aggregate amount available to be drawn under each DLC Letter of Credit during
the preceding quarter (or shorter period commencing with the Closing Date) at a
rate per annum equal to the applicable LIBO Rate Margin from time to time in
effect during such period pursuant to Section 2.06 and (ii) for the account of
the Issuing Bank, a fee on the average daily aggregate amount available to be
drawn under each DLC Letter of Credit during the preceding quarter (or shorter
period commencing with the Closing Date) at a rate per annum equal to 0.25%.
Such fees shall be computed on the basis of the actual number of days elapsed in
a year of 360 days. Such fees shall accrue from and including the Closing Date
to but excluding the last day of the DLC Letter of Credit Availability Period.
In addition to the foregoing, the Borrower shall pay directly to the Issuing
Bank, for its account, payable within 15 days after written demand therefor by
the Issuing Bank has been received by the Borrower, the Issuing Bank's
out-of-pocket expenses and customary fees in connection with the issuance,
transfer or amendment of or payment on each DLC Letter of Credit.

                  (g) The Borrower hereby agrees to reimburse the Issuing Bank
for any payment or disbursement made by the Issuing Bank under each DLC Letter
of Credit, by making payment in immediately available funds to the
Administrative Agent within one Business Day after receipt of notice of such
payment or disbursement, in an amount equal to the amount of such payment or
disbursement, plus interest on the amount so paid or disbursed by the Issuing
Bank, to the extent not reimbursed prior to 12:00 p.m. (New York City time) on
the date of such payment or disbursement, from and including the date paid or
disbursed to but excluding the date the Issuing Bank is reimbursed by the
Borrower therefor, at a rate per annum equal to the rate applicable to Base Rate
Revolving Loans during such period pursuant to Section 2.06. In the event the
Borrower fails to reimburse the Issuing Bank as required by the preceding
sentence, the Issuing Bank shall so notify the Administrative Agent and such
payment or disbursement shall be reimbursed to the Issuing Bank as contemplated
by Section 2.03(c) or Section 2.16(d), as applicable. The Issuing Bank shall
give the Borrower prompt notice of each drawing under any DLC Letter of Credit,
provided, that, the failure to give any such notice shall in no way affect,
impair or diminish the Borrower's obligations hereunder. The Administrative
Agent shall promptly pay any such amounts received by it to the Issuing Bank.

                  (h) The Borrower's obligation to reimburse DLC Letter of
Credit Disbursements as provided in Section 2.16(g) shall be absolute,
unconditional and irrevocable and shall be performed strictly in accordance with
the terms of this Agreement under any and all circumstances, including the
following:

                                       54
<PAGE>   61

                           (i) any lack of validity or enforceability of any DLC
                  Letter of Credit or any other Financing Document;

                           (ii) except as otherwise provided in clause (iv) of
                  this Section 2.16(h), the existence of any claim, setoff,
                  defense or other right which the Borrower, any Affiliate or
                  any other person may at any time have against the beneficiary
                  under a DLC Letter of Credit, the Issuing Bank, the
                  Administrative Agent, any Revolving Lender or any other person
                  in connection with this Agreement, any other Financing
                  Document or any other related or unrelated agreement or
                  transaction;

                           (iii) any draft or other document presented under any
                  DLC Letter of Credit proving to be forged, fraudulent, invalid
                  or insufficient in any respect or failing to comply with the
                  Uniform Customs and Practices for Documentary Credits, as in
                  effect from time to time, or any statement therein being
                  untrue or inaccurate in any respect;

                           (iv) payment by the Issuing Bank under any DLC Letter
                  of Credit against presentation of a draft or other document
                  which does not comply with the terms of such DLC Letter of
                  Credit; provided, that, such payment was not wrongfully made
                  as a result of the gross negligence or willful misconduct of
                  the Issuing Bank;

                           (v) any amendment, waiver or consent in respect of
                  this Agreement or any other Financing Document; and

                           (vi) any other act or omission or delay of any kind
                  or any other circumstance or event whatsoever, whether or not
                  similar to any of the foregoing and whether or not
                  foreseeable, that might, but for the provisions of this
                  Section 2.16(h), constitute a legal or equitable discharge of
                  the Borrower's obligations hereunder.

                  (i) It is expressly understood and agreed that, for purposes
of determining whether a wrongful payment under a DLC Letter of Credit resulted
from the Issuing Bank's gross negligence or willful misconduct, (i) the Issuing
Bank's acceptance of documents that appear on their face to comply with the
requirements of such DLC Letter of Credit, without responsibility for further
investigation, regardless of any notice or information to the contrary, (ii) the
Issuing Bank's exclusive reliance on the documents presented to it under such
DLC Letter of Credit as to any and all matters set forth therein, including the
amount of any draft presented under such DLC Letter of Credit, whether or not
the amount due to the beneficiary thereunder equals the amount of such draft and
whether or not any document presented pursuant to such DLC Letter of Credit
proves to be insufficient in any respect (so long as such document on its face
appears to comply with the requirements of the applicable DLC Letter of Credit),
and whether or not any other statement or any other document presented pursuant
to such DLC Letter of Credit proves to be forged or invalid or any statement
therein proves to be inaccurate or untrue in any respect whatsoever and (iii)
any noncompliance in any immaterial respect of the

                                       55
<PAGE>   62

documents presented under such DLC Letter of Credit with the terms thereof
shall, in each case, be deemed not to constitute willful misconduct or gross
negligence of the Issuing Bank. It is further understood and agreed that,
notwithstanding the proviso to clause (iv) of Section 2.16(h), the Borrower's
obligation hereunder to reimburse Letter of Credit Disbursements will not be
excused by the gross negligence or willful misconduct of the Issuing Bank to the
extent that the DLC Letter of Credit Disbursement actually discharged a
liability of, or otherwise benefited, or was recovered by, the Borrower;
provided, that, the foregoing shall not be construed to excuse the Issuing Bank
from liability to the Borrower to the extent of any direct damages suffered by
the Borrower that are caused by the Issuing Bank's gross negligence or willful
misconduct in determining whether drafts and other documents presented under the
applicable DLC Letter of Credit comply with the terms thereof.

                  (j) The Issuing Bank shall, promptly following its receipt
thereof, examine all documents purporting to represent a demand for payment
under a DLC Letter of Credit. The Issuing Bank shall as promptly as possible
give telephonic notification, confirmed by telex or telecopy, to the
Administrative Agent and the Borrower of such demand for payment and whether the
Issuing Bank has made or will make the DLC Letter of Credit Disbursement
thereunder; provided, that, the failure to give such notice shall not relieve
the Borrower of its obligation to reimburse the DLC Letter of Credit
Disbursement in accordance with this Section 2.16. The Administrative Agent
shall promptly give each Revolving Lender notice thereof.

                  (k) The Borrower shall use each DLC Letter of Credit solely to
support its obligations under the POLR Agreement or the POLR II Agreement as
required thereby.

                  (l) In the event that the Borrower is required pursuant to the
terms of this Agreement to provide cash collateral in respect of the DLC Letter
of Credit Exposure, the Borrower shall deposit in an account with the
Administrative Agent, for the benefit of each Lender having a Revolving Loan
Commitment, an amount in cash equal to the DLC Letter of Credit Exposure (or
such lesser amount as shall be required hereunder or thereunder). Such deposit
shall be held by the Administrative Agent as collateral for the payment and
performance of any outstanding DLC Letter of Credit Exposure. The Administrative
Agent shall have exclusive dominion and control, including the exclusive right
of withdrawal, over such account. Moneys in such account shall be held and
applied by the Administrative Agent in accordance with the Deposit Account
Agreement.

                  Section 2.17      Operational Letters of Credit.

                  (a) The Borrower may request the issuance of Operational
Letters of Credit, for the account of the Borrower, at any time during the
Operational Letter of Credit Availability Period; provided, that, any
Operational Letter of Credit shall be issued only if (and a request by the
Borrower for the issuance of any Operational Letter of Credit shall be deemed a
representation and warranty of the Borrower that) immediately following the
issuance of such Operational Letter of Credit, (i) the Operational Letter of

                                       56
<PAGE>   63

Credit Exposure shall not exceed $5,000,000, and (ii) the sum of the aggregate
Letter of Credit Exposure and the aggregate principal amount of outstanding
Revolving Loans at such time shall not exceed the lesser of (y) the aggregate
Revolving Loan Commitments at such time and (z) the Maximum Revolving Loan
Amount effective as of such time.

                  (b) Each Operational Letter of Credit shall expire at 5:00
p.m., New York City time, on the last day of the Operational Letter of Credit
Availability Period, unless such Operational Letter of Credit expires by its
terms (or is required by Section 2.17(c) to expire) on an earlier date. Each
Operational Letter of Credit shall provide for payments of drawings in Dollars.

                  (c) Each issuance of any Operational Letter of Credit shall be
made on at least three Business Days' prior irrevocable written or telecopy
notice (such notice to be delivered by 10:00 a.m., New York City time) from the
Borrower (or such shorter notice as shall be acceptable to the Issuing Bank) to
the Administrative Agent and the Issuing Bank, specifying whether such
Operational Letter of Credit is a standby letter of credit or a trade letter of
credit, the date of issuance, the date on which such Operational Letter of
Credit is to expire (which shall not be later than (i) in all events, the last
day of the Operational Letter of Credit Availability Period and (ii)(A) in the
case of standby letters of credit, subject to extension, one year after the date
of issuance of such Operational Letter of Credit and (B) in the case of trade
letters of credit, 180 days after the date of issuance of such Operational
Letter of Credit), the amount of such Operational Letter of Credit, the name and
address of the beneficiary of such Operational Letter of Credit, and such other
information as may be necessary or desirable to complete such Operational Letter
of Credit. The Issuing Bank will give the Administrative Agent prompt notice of
the issuance and amount of such Operational Letter of Credit and the expiration
date of such Operational Letter of Credit (and the Administrative Agent shall
give prompt notice thereof to each Revolving Lender). Each Operational Letter of
Credit issued hereunder will be subject to the Uniform Customs and Practices for
Documentary Credits, as in effect from time to time.

                  (d) By the issuance of an Operational Letter of Credit and
without any further action on the part of the Issuing Bank, the Administrative
Agent or the Revolving Lenders in respect thereof, the Issuing Bank hereby
grants to each Revolving Lender, and each Revolving Lender hereby acquires from
the Issuing Bank, a participation in such Operational Letter of Credit equal to
such Revolving Lender's Pro Rata Share (based on such Revolving Lender's
Revolving Loan Commitment) of the aggregate amount available to be drawn under
such Operational Letter of Credit, effective upon the issuance of such
Operational Letter of Credit. In consideration and in furtherance of the
foregoing, each Revolving Lender having a Revolving Loan Commitment hereby
absolutely and unconditionally agrees to pay to the Administrative Agent, on
behalf of the Issuing Bank, in accordance with Section 2.03(c), such Revolving
Lender's Pro Rata Share (based on such Revolving Lender's Revolving Loan
Commitment) of each Operational Letter of Credit Disbursement made by the
Issuing Bank and not reimbursed by the Borrower when due in accordance with
Section 2.17(g); provided, that, the Revolving Lenders shall not be obligated to
make any such payment with respect to any wrongful Operational

                                       57
<PAGE>   64

Letter of Credit Disbursement made as a result of the gross negligence or
willful misconduct of the Issuing Bank.

                  (e) Each Revolving Lender acknowledges and agrees that its
obligation to acquire participations pursuant to Section 2.17(d) in respect of
Operational Letters of Credit is absolute and unconditional and shall not be
affected by any circumstance whatsoever, including the occurrence and
continuance of a Default or Event of Default, and that each such payment shall
be made without any offset, abatement, withholding or reduction whatsoever
(subject only to the proviso set forth in the last sentence of Section 2.17(d))

                  (f) During the Operational Letter of Credit Availability
Period, the Borrower shall pay to the Administrative Agent, on each Quarterly
Payment Date in each year and on the date on which the Revolving Loan
Commitments shall be terminated as provided herein, (i) for the account of the
Revolving Lenders, ratably in proportion to their Revolving Loan Commitments, a
fee on the average daily aggregate amount available to be drawn under all
outstanding Operational Letters of Credit during the preceding quarter (or
shorter period commencing with the Closing Date) at a rate per annum equal to
the applicable LIBO Rate Margin from time to time in effect during such period
pursuant to Section 2.06 and (ii) for the account of the Issuing Bank, a fee on
the average daily aggregate amount available to be drawn under all outstanding
Operational Letters of Credit during the preceding quarter (or shorter period
commencing with the Closing Date) at a rate per annum equal to 0.25%. Such fees
shall be computed on the basis of the actual number of days elapsed in a year of
360 days. Such fees shall accrue from and including the Closing Date to but
excluding the last day of the Operational Letter of Credit Availability Period.
In addition to the foregoing, the Borrower shall pay directly to the Issuing
Bank, for its account, payable within 15 days after written demand therefor by
the Issuing Bank has been received by the Borrower, the Issuing Bank's
out-of-pocket expenses in connection with the issuance, transfer or amendment of
or payment on any Operational Letter of Credit.

                  (g) The Borrower hereby agrees to reimburse the Issuing Bank
for any payment or disbursement made by the Issuing Bank under any Operational
Letter of Credit, by making payment in immediately available funds to the
Administrative Agent within one Business Day after receipt of notice of such
payment or disbursement, in an amount equal to the amount of such payment or
disbursement, plus interest on the amount so paid or disbursed by the Issuing
Bank, to the extent not reimbursed prior to 12:00 p.m. (New York City time) on
the date of such payment or disbursement, from and including the date paid or
disbursed to but excluding the date the Issuing Bank is reimbursed by the
Borrower therefor, at a rate per annum equal to the rate applicable to Base Rate
Revolving Loans during such period pursuant to Section 2.06. In the event the
Borrower fails to reimburse the Issuing Bank as required by the preceding
sentence, the Issuing Bank shall so notify the Administrative Agent and such
payment or disbursement shall be reimbursed to the Issuing Bank as contemplated
by Section 2.03(c) or Section 2.17(d), as applicable. The Issuing Bank shall
give the Borrower prompt notice of each drawing under any Operational Letter of
Credit, provided, that, the failure to give any such notice

                                       58
<PAGE>   65

shall in no way affect, impair or diminish the Borrower's obligations hereunder.
The Administrative Agent shall promptly pay any such amounts received by it to
the Issuing Bank.

                  (h) The Borrower's obligation to reimburse Operational Letter
of Credit Disbursements as provided in Section 2.17(g) shall be absolute,
unconditional and irrevocable and shall be performed strictly in accordance with
the terms of this Agreement under any and all circumstances, including the
following:

                           (i) any lack of validity or enforceability of any
                  Operational Letter of Credit or any other Financing Document;

                  this Section 2.17(h), the existence of any claim, setoff,
                  defense or other right which the Borrower, any Affiliate or
                  any other person may at any time have against the beneficiary
                  under any Operational Letter of Credit, the Issuing Bank, the
                  Administrative Agent, any Revolving Lender or any other person
                  in connection with this Agreement, any other Financing
                  Document or any other related or unrelated agreement or
                  transaction;

                           (iii) any draft or other document presented under an
                  Operational Letter of Credit proving to be forged, fraudulent,
                  invalid or insufficient in any respect or failing to comply
                  with the Uniform Customs and Practices for Documentary
                  Credits, as in effect from time to time, or any statement
                  therein being untrue or inaccurate in any respect;

                  Letter of Credit against presentation of a draft or other
                  document which does not comply with the terms of such
                  Operational Letter of Credit; provided, that, such payment was
                  not wrongfully made as a result of the gross negligence or
                  willful misconduct of the Issuing Bank;

                           (v) any amendment, waiver or consent in respect of
                  this Agreement or any other Financing Document; and

                  or any other circumstance or event whatsoever, whether or not
                  similar to any of the foregoing and whether or not
                  foreseeable, that might, but for the provisions of this
                  Section 2.17(h), constitute a legal or equitable discharge of
                  the Borrower's obligations hereunder.

reliance on the documents presented to it under such Operational Letter of
Credit as to any and all matters set forth therein, including the amount of any
draft presented under such Operational Letter of Credit, whether or not the
amount due to the beneficiary thereunder equals the amount of such draft and
whether or not any document presented pursuant to such Operational Letter of
Credit proves to be insufficient in any respect (so long as such document on its
face appears to comply with the requirements of such Operational Letter of
Credit), and whether or not any other statement or any other document presented
pursuant to such Operational Letter of Credit proves to be forged or invalid or
any statement therein proves to be inaccurate or untrue in any respect
whatsoever and (iii) any noncompliance in any immaterial respect of the
documents presented under such Operational Letter of Credit with the terms
thereof shall, in each case, be deemed not to constitute willful misconduct or
gross negligence of the Issuing Bank. It is further understood and agreed that,
notwithstanding the proviso to clause (iv) of Section 2.17(h), the Borrower's
obligation hereunder to reimburse Operational Letter of Credit Disbursements
will not be excused by the gross negligence or willful misconduct of the Issuing
Bank to the extent that such Operational Letter of Credit Disbursement actually
discharged a liability of, or otherwise benefited, or was recovered by, the
Borrower; provided, that, the foregoing shall not be construed to excuse the
Issuing Bank from liability to the Borrower to the extent of any direct damages
suffered by the Borrower that are caused by the Issuing Bank's gross negligence
or willful misconduct in determining whether drafts and other documents
presented under an Operational Letter of Credit comply with the terms thereof.

             (j) The Issuing Bank shall, promptly following its receipt thereof,
examine all documents purporting to represent a demand for payment under an
Operational Letter of Credit. The Issuing Bank shall as promptly as possible
give telephonic notification, confirmed by telex or telecopy, to the
Administrative Agent and the Borrower of such demand for payment and whether the
Issuing Bank has made or will make the Operational Letter of Credit Disbursement
thereunder; provided, that, the failure to give such notice shall not relieve
the Borrower of its obligation to reimburse Operational Letter of Credit
Disbursement in accordance with this Section 2.17. The Administrative Agent
shall promptly give each Revolving Lender notice thereof.

             (k) The Borrower shall use the Operational Letters of Credit solely
to support various financial and other payment or performance obligations of the
Borrower incurred in the ordinary course of business including, without
limitation, any expansion, repowering, maintenance, repairs or capital
expenditures.

             (l) In the event that the Borrower is required pursuant to the
terms of this Agreement to provide cash collateral in respect of the Operational
Letter of Credit Exposure, the Borrower shall deposit in an account with the
Administrative Agent, for the benefit of each Lender having a Revolving Loan
Commitment, an amount in cash equal to the Operational Letter of Credit Exposure
(or such lesser amount as shall be required hereunder or thereunder). Such
deposit shall be held by the Administrative Agent as collateral for the payment
and performance of any outstanding Operational Letter of Credit Exposure. The
Administrative Agent shall have exclusive dominion and control,

                                       60

activities makes such qualification necessary and (d) is in full compliance
with its Governing Documents, all Contractual Obligations, all applicable
Requirements of Law and all of its Governmental Approvals, except to the extent
that the failure to comply therewith could not reasonably be expected to have a
Material Adverse Effect.

      Section 4.02 Power; Authority; No Violation; Binding Effect. (a) The
execution, delivery and performance by the Borrower of the Transaction
Documents to which it is a party and the consummation of the transactions
contemplated thereby (i) are within its powers, (ii) have been duly authorized

its Governing Documents or (B) any material Requirement of Law, any material
Contractual Obligation or any material Governmental Approval binding on or

provisions of, or constitute a default under, or result in the creation or
imposition of (or the obligation to create or impose) any Lien (except

any material Contractual Obligation binding on or affecting it.

      (b)   The Borrower has duly executed and delivered each Transaction
Document to which it is a party. Each Transaction Document constitutes the
legal, valid and binding obligation of the Borrower (to the extent it is a
party thereto), enforceable against the Borrower in accordance with its terms,
except as enforcement thereof may be subject to (i) the effect of any
applicable bankruptcy, insolvency, reorganization,

                                       68
<PAGE>   75

moratorium or similar laws affecting creditors' rights generally and (ii)
general principles of equity.

or valid leasehold, easement or right-of-way interests in, the material
property, assets or revenues which it purports to own, lease or hold any such
interest in, free and clear of all Liens (except Permitted Liens), including
possession of all required real estate interests and licenses, Intellectual
Property and other proprietary rights.

      Section 4.04 Governmental Approvals. (i) Except as otherwise set forth on
Schedule 4.04 attached hereto, no Governmental Approval or approval of any
other Person (except such as have been duly obtained, made or given, and are in
full force and effect or the failure to obtain which is not material to the
ongoing operation of any Portfolio Asset) is required to authorize, or is
required in connection with (a) the execution, delivery or performance of any
Transaction Document by the Borrower or the consummation of any of the
transactions contemplated thereby (including, without limitation, the purchase
of the Portfolio Assets and the granting of Liens pursuant to the Security
Documents), (b) the ownership, maintenance or operation of the Portfolio Assets
by the Borrower (other than Governmental Approvals that may be required for the
operation of Phillips, which shall not be necessary unless and until the
Borrower elects to place such Portfolio Asset into operation) or (c) the
legality, validity, binding effect or enforceability of any Transaction
Document. Except as otherwise set forth on Part C of Schedule 4.04, all
applicable waiting periods (including appeal periods) relating to any such

4.04, is in full force and effect, is not subject to any appeal or similar
proceeding, except as such appeal or similar proceeding is expressly described
on Part C of Schedule 4.04. The Borrower has no reason to believe, after
reasonable inquiry, that as of the Closing Date, any of the Governmental
Approvals and other consents and approvals listed on Part D of Schedule 4.04
cannot or will not be obtained or made in the normal course of business as and
when required and without material expense or delay. The Borrower is not in
violation of any condition in any of its material Governmental Approvals.

attached hereto, there is no (a) injunction, writ, preliminary restraining
order or order of any nature issued by an arbitrator, court or other
Governmental Authority against the Borrower, or, to the Borrower's knowledge,
against any other Major Project Party, in connection with the transactions
provided for herein or in the other Transaction Documents, or (b) action, suit,
arbitration, litigation, investigation or proceeding of or before any
arbitrator or Governmental Authority pending against (i) the Borrower or, to
the Borrower's knowledge, threatened against the Borrower nor, to the

hereby or thereby. To the knowledge of the Borrower based on such inquiry, all

(and with the approval of), the Borrower on commercially reasonable terms for

material adverse effect on the operation of any Portfolio Asset.

prior to the date hereof, true, correct and complete copies of the Project
Contracts in effect as of the date hereof and all of the Governing Documents of

require material changes to the Portfolio Assets, or the operation thereof, to
comply with Environmental Laws in the future, except in any such case where

audit, they have become aware of any Default or Event of Default and, if any

resolve such dispute; and provided, further, that if an Operating Budget is not

its or their own gross negligence or willful misconduct.

      Section 8.02 Reliance by Agents. Each Agent and the Issuing Bank shall be
entitled to rely upon any certificate, notice or other document (including any
cable, telegram, telecopy or telex) believed by it to be genuine and correct
and to have been signed or sent by or on behalf of the proper Person or
Persons, and upon advice and statements of legal counsel, independent
accountants and other experts selected by such Agent or the Issuing Bank. As to
any matters related to this Agreement or the transactions contemplated hereby,
none of the Agents nor the Issuing Bank shall be required to take any action or
exercise any discretion, but the Agents and the Issuing Bank shall be required
to act or to refrain from acting upon instructions of the Required Lenders and
shall in all cases be fully protected in acting, or in refraining from acting,
hereunder or under any other Transaction Document in accordance with the
instructions of the Required Lenders, and such instructions of the Required
Lenders and any action taken or failure to act pursuant thereto shall be
binding on all of the Secured Parties.

      Section 8.03 Defaults. The Administrative Agent shall not be deemed to
have actual knowledge or notice of the occurrence of a Default or an Event of
Default unless the Administrative Agent has received notice from a Lender or the
Borrower referring to this Agreement, describing such Default or Event of
Default and stating that such notice is a "Notice of Default". In the event that
the Administrative Agent receives such a notice of the occurrence of a Default
or an Event of Default the Administrative Agent shall give notice thereof to the
Secured Parties. The Administrative Agent shall take such action with respect to
such Default or Event of Default as shall be reasonably directed by the Required
Lenders (or, if required by Section 9.02, as shall be reasonably directed by all
of the Lenders); provided that, unless and until the Administrative Agent shall
have received such directions, the Administrative Agent may (but shall not be
obligated to) take such action, or refrain from taking such action, with respect
to such

                                       99

<PAGE>   106
Default or Event of Default as it shall deem advisable in the best interest of
the Secured Parties.

      Section 8.04 Rights as Lenders. With respect to its commitment to make
Loans, Bank of America, N.A. shall have the same rights and powers hereunder as
any Lender and may exercise the same as though it was not acting as the
Administrative Agent and the term "Lender" or "Lenders" shall, unless the
context otherwise indicates, include Bank of America, N.A. in its individual
capacity. Bank of America, N.A. and its Affiliates may (without having to
account therefor to any Lender) accept deposits from, extend credit (on a
secured or unsecured basis) to and generally engage in any kind of banking,
trust or other business with the Borrower or any of its Affiliates, as if it
were not acting as the Administrative Agent.

      Section 8.05 Indemnification. Without limiting the obligations of the
Borrower under Section 9.04 hereof, each Lender agrees to indemnify each Agent,
the Issuing Bank and the Arrangers, ratably in accordance with the aggregate
principal amount of the Loans and Letter of Credit Exposure held by the
Lenders, or, if no Loans are then outstanding, the respective amounts of the
Lenders' Commitments, for any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
or any kind or nature whatsoever which may at any time (including, without
limitation, at any time following the payment of principal of and/or interest
on the Loans) be imposed on, incurred by or asserted against any Agent, the
Issuing Bank or any Arranger in any way relating to or arising out of this
Agreement or any documents contemplated by or referred to herein or therein or
the transactions contemplated hereby or thereby (including the costs and
expenses which the Borrower is obligated to pay under Section 9.04 hereof) or
the enforcement of any of the terms hereof or thereof or of any such other
documents, provided that no Lender shall be liable for any of the foregoing to
the extent they arise from any Agent's, the Issuing Bank's or any Arranger's
gross negligence or willful misconduct as determined by a court of competent
jurisdiction. The Agents, the Issuing Bank and the Arrangers shall be fully
justified in refusing to take or to continue to take any action hereunder
unless it shall first be indemnified to its satisfaction by the Lenders against
any and all liability and expense which may be incurred by it by reason of
taking or continuing to take any such action.

      Section 8.06 Documents. The Administrative Agent will forward to each
Lender, promptly after the Administrative Agent's receipt thereof, a copy of
each document furnished to the Administrative Agent for such Secured Party
hereunder (and a copy of such other documents furnished to the Administrative
Agent pursuant to Article III hereof as may be requested by such Lender).

      Section 8.07 Non-Reliance on Agents and Other Lenders. Each Lender
represents that it has, independently and without reliance on any Agent, the
Issuing Bank, any Arranger, or any other Lender, and based on such documents
and information as it has deemed appropriate, made its own appraisal of the
financial condition and affairs of the Borrower and its own decision to enter
into this Agreement and agrees that it will, independently and without reliance
upon any Agent, the Issuing Bank, any Arranger or any other Lender, and based
on such documents and information as it shall deem

                                      100

<PAGE>   107

appropriate at the time, continue to make its own appraisals and decisions in
taking or not taking action under this Agreement. None of the Agents, the
Issuing Bank, any Arranger or any Lender shall be required to keep informed as
to the performance or observance by the Borrower under this Agreement or any
other document referred to or provided for herein or to make inquiry of, or to
inspect the properties or books of, the Borrower. Except for notices, reports
and other documents and information expressly required to be furnished to the
Lenders by any Agent, the Issuing Bank, or any Arranger hereunder, none of the
Agents, the Issuing Bank, any Arranger or any Lender shall have any duty or
responsibility to provide any Lender with any credit or other information
concerning the Borrower, or any Affiliate of the Borrower, which may come into
the possession of such Agent, the Issuing Bank, any Arranger or such Lender or
any of its or their Affiliates.

      Section 8.08 Resignation. Subject to the appointment and acceptance of a
successor as provided below, each of the Agents and the Issuing Bank (prior to
the issuance of the DLC Letter of Credit) may resign at any time by giving
notice thereof to the Lenders and the Borrower. Upon any such resignation, the
Required Lenders shall have the right to appoint a successor Agent and/or
Issuing Bank, as applicable, which shall be a Lender hereunder. If no successor
Agent and/or Issuing Bank, as applicable, shall have been appointed by the
Required Lenders and no Lender shall have accepted such appointment within 30
days after the retiring Agent's and/or Issuing Bank's giving of notice of
resignation, then the retiring Agent may, on behalf of the Lenders, appoint a
successor Agent and/or Issuing Bank, which shall be a Lender hereunder having a
combined capital and surplus of not less than $500,000,000. Upon the acceptance
of any appointment as an Agent and/or Issuing Bank, as applicable, hereunder by
a successor Agent and/or Issuing Bank, as the case may be, such successor Agent
and/or Issuing Bank shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Agent and/or Issuing
Bank, and the retiring Agent and/or Issuing Bank shall be discharged from its
duties and obligations hereunder. After any retiring Agent's and/or Issuing
Bank's resignation hereunder as Agent and/or Issuing Bank, the provisions of
this Article VIII shall continue in effect for its benefit in respect of any
actions taken or omitted to be taken by it while it was acting as Agent and/or
Issuing Bank.

      Section 8.09 Authorization. The Administrative Agent and the Issuing Bank
are hereby authorized by the Lenders to execute, deliver and perform each of
the Transaction Documents to which they (whether as "Administrative Agent",
"Issuing Bank", "Secured Party", "Grantee" or "Mortgagee") are or are intended
to be a party and each Lender agrees to be bound by all of the agreements of
the Administrative Agent and the Issuing Bank respectively, contained in the
Transaction Documents.

      Section 8.10 Documentation Agents; Syndication Agents; Joint Book
Runners, Arrangers. Nothing in this Agreement shall create or impose on any
Documentation Agent, Syndication Agent, Joint Book Runner or Arranger, in each
case in such capacity, any duty, obligation or responsibility whatsoever to any
Person.

      Section 9.02 Amendments, Etc.. No amendment or waiver of any provision of
any Financing Document, nor consent to any departure by any Credit Party
therefrom, shall in any event be effective unless the same shall be in writing
and signed by the Required Lenders and the Administrative Agent or Issuing
Bank, as the case may be, or if the Lenders shall not be parties thereto, by
the parties thereto and consented to by the Required Lenders, and each such
amendment, waiver or consent shall be effective only in the specific instance
and for the specific purpose for which given; provided, that, no amendment,
waiver or consent shall, unless in writing and signed by all the Lenders, do

the Lenders to any additional obligations, (ii) reduce the principal of, or

that no amendment, waiver or consent affecting the rights or duties of the
Administrative Agent or the Issuing Bank under any Financing Document shall in

Agent or the Issuing Bank, as the case may be, in addition to the Lenders
required hereinabove to take such action. Notwithstanding any of the foregoing
to the contrary, the consent of the Borrower shall not be required for any
amendment, modification or waiver of the provisions of Article VIII (other than
the provisions of Section 8.08). In addition, the Borrower, the Arrangers, the
Lenders and the Swap Banks hereby authorize the Administrative Agent to modify
this Agreement by amending or supplementing Annexes

                                      102

and each Secured Party.

      Section 9.03 No Waiver; Remedies Cumulative. No failure or delay on the
part of any Secured Party or any holder of a Note in exercising any right or
remedy under any Financing Document and no course of dealing between the
Borrower and any Secured Party or the holder of any Note shall operate as a
waiver thereof, nor shall any single or partial exercise of any right or remedy
under any Financing Document preclude any other or further exercise thereof or
the exercise of any other right or remedy hereunder. The rights and remedies
herein expressly provided are cumulative and not exclusive of any rights or
remedies which the Secured Parties or the holder of any Note would otherwise
have. No notice to or demand on the Borrower not required under any Financing
Document shall entitle the Borrower to any other or further notice or demand in
similar or other circumstances or constitute a waiver of the rights of any
Secured Party or the holder of any Note to any other or further action in any
circumstances without notice or demand.

      Section 9.04 Payment of Expenses and Indemnification. The Borrower shall:

      take possession of, release or liquidate any of the Collateral or (e) to

      Credit or the proceeds of any of the Loans or any Credit Party's entering
      into and performing of this Agreement or any of the other Financing
      Documents and the Transaction Documents, together with the reasonable
      fees and disbursements of attorneys and paralegals (including charges for

      resulting from the gross negligence or willful misconduct of such
      Indemnified Person; and

            (v)   indemnify each Indemnified Person from, and hold each
      Indemnified Person harmless against, any and all costs, losses,

this Section 9.04 are unenforceable for any reason, the Borrower hereby agrees
to make the maximum contribution to the payment and satisfaction of such
obligations which is permissible under applicable Requirement of Law. The
Borrower's obligations under this Section 9.04 shall survive any termination of
this Agreement and the payment of the Notes.

rights of offset that any Lender or other holder of a Note may have under
applicable Requirement of Law, each Lender or other holder of a Note shall,
upon the occurrence and during the continuance of any Event of Default and
whether or not such Lender or such holder has made any demand or the
Obligations of the Borrower are matured, have the right to appropriate and
apply to the payment of the Obligations of the Borrower all deposits (general
or special, time or demand, provisional or final) then or thereafter held by
and other indebtedness or property then or thereafter owing by such Lender or
other holder, whether or not related to this Agreement or any transaction
hereunder. Any amount received as a result of the exercise of such rights shall
be re-allocated among the Lenders as set forth in Section 2.13 and the Borrower
shall receive prompt notice thereof from the Administrative Agent; provided,
that any failure by the Administrative Agent to provide such notice shall in no
way affect the rights of any Lender or other holder of a Note under this
Section 9.05.

Agent, not to be unreasonably withheld, conditioned or delayed, if such
proposed assignment is not to an existing Lender or an Affiliate of an existing
Lender, after consultation with the Borrower) to one or more banks or other
entities all or a portion of its rights and obligations under this Agreement,
the Notes and the Letters of Credit; provided that no such assignment shall be
for less than $5,000,000 of such Lender's Commitments or Loans, as the case may
be. Upon such execution, delivery and

                                      105

acceptance, from and after the effective date (the "Effective Date") of such
Assignment and Acceptance (x) the assignee thereunder shall be a party hereto,
and, to the extent that rights and obligations hereunder have been assigned to
and assumed by it pursuant to such Assignment and Acceptance, such assignee
shall have the rights and obligations of a Lender hereunder and (y) the Lender
assignor thereunder shall, to the extent that rights and obligations hereunder
have been assigned by it pursuant to such Assignment and Acceptance, relinquish
its rights and be released from its obligations under this Agreement (and, in
the case of an Assignment and Acceptance covering all or the remaining portion

assignee thereunder confirms and agrees as follows: (i) other than as provided
in such Assignment and Acceptance, the assigning Lender makes no representation
or warranty and assumes no responsibility with respect to any statements,

terms hereof, together with such powers as are reasonably incidental thereto
and (vi) such assignee agrees that it will perform in accordance with their
terms all of the obligations which by the terms of this Agreement are required

      (e)   The Administrative Agent shall maintain at its address referred to

accepted by it and a register for the recordation of the names and addresses of
the Lenders and the Commitments of, and principal amount of the Loans owing to,
each Lender from time to time (the "Register"). The entries in the Register
shall be conclusive and binding for all purposes, absent manifest error, and
the Borrower and each Secured Party may treat each Person whose name is
recorded in the Register as a Lender hereunder for all purposes of this
Agreement. The Register and copies of each Assignment and Acceptance shall be

reasonable time and from time to time upon reasonable prior notice.

      (f)   Upon its receipt of an Assignment and Acceptance executed by an

completed and is in substantially the form of Exhibit K hereto, (i) accept such
Assignment and Acceptance, (ii) record the information contained therein in the

in an amount equal to the Commitment or Commitments assumed by it pursuant to
such Assignment and Acceptance and, if the assigning Lender has retained a
Commitment or Commitments hereunder, a new Note or Notes to the order of the
assigning Lender in an amount equal to the Commitment or Commitments retained
by it hereunder. Such new Note or Notes shall re-evidence the indebtedness
outstanding under the old Notes or Notes and shall be in an aggregate principal
amount equal to the aggregate principal amount of such surrendered Note or
Notes, shall be dated the effective date of such Assignment and Acceptance and
shall otherwise be in substantially the form of the Note or Notes subject to
such assignments.

one or more parties in or to all or a portion of its rights and obligations
under this Agreement (including, without limitation, all or a portion of its
Commitment, the Loans owing to it and the Note or Notes held by it and the
participations in the Letters of Credit held by it); provided that (i) such
Lender's obligations under this Agreement (including, without limitation, its
Commitment) shall remain unchanged, (ii) such Lender shall remain solely
responsible to other parties hereto for the performance of such obligations,
(iii) such Lender shall remain the holder of any such Note for all purposes of
this Agreement, (iv) the Borrower, the Administrative Agent, the Issuing Bank
and the other Lenders shall continue to deal solely and directly with such
Lender in connection with such Lender's rights and obligations under this
Agreement and (v) such Lender shall not transfer, grant, assign or sell any
participation under which the participant shall have rights to approve any
amendment or waiver of this Agreement except to the extent such amendment or
waiver would (A) extend the final maturity date or the date for the payments of
any installment of fees or principal or interest of any Loans in which such
participant is participating, (B) reduce the amount of any installment of
principal of the Loans in which such participant is participating, (C) reduce
the interest rate applicable to the Loans in which such participant is

substantially all of the Collateral.

      (h)   Each Lender agrees that, without the prior written consent of the
Borrower and the Administrative Agent, it will not make any assignment
hereunder in any manner or under any circumstances that would require
registration or qualification of,

                                      107

<PAGE>   114

or filings in respect of, any Loan, Note or other Obligation under the
securities laws of the United States of America or of any state.

      (i)   Any Lender may at any time assign all or any portion of its rights
under this Agreement and the other Financing Documents to the Federal Reserve
Bank of the United States; provided, that any payment in respect of such
assigned rights made by the Borrower to the assigning Lender in accordance with
the terms of this Agreement shall satisfy the Borrower's obligations hereunder
in respect of such assigned rights to the extent of such payment. No such
assignment shall release the assignor Lender from its obligations hereunder.

      (j)   After the completion of the primary and general syndication of the
Loans described herein, each transferor Lender shall pay the Administrative
Agent a fee of $2,000 in the case of an assignment to an existing Lender or an
Affiliate of an existing Lender or $3,500.00 in all other cases, for processing
each assignment made pursuant to this Section 9.06.

WITH THE LAWS OF THE STATE OF NEW YORK OTHER THAN ANY SUCH REQUIREMENT OF LAWS
THAT WOULD APPLY THE LAWS OF ANOTHER JURISDICTION, EXCEPT TO THE EXTENT THAT
THE LAWS OF ANOTHER JURISDICTION ARE MANDATORILY APPLICABLE. ANY DISPUTE
ARISING OUT OF, CONNECTED WITH, RELATED TO, OR INCIDENTAL TO THE RELATIONSHIP
ESTABLISHED BETWEEN THE BORROWER AND EACH SECURED PARTY IN CONNECTION WITH THIS

PROCEEDINGS OR OTHERWISE PROCEED AGAINST ANY PARTY IN ANY OTHER JURISDICTION.

      Section 9.08 Nonliability of Administrative Agent and Lenders. The
relationship between the Borrower and the Secured Parties shall be solely that
of borrower and lender. No Secured Party shall have any fiduciary
responsibilities to the Borrower. No Secured Party undertakes any
responsibility to the Borrower to review or inform the Borrower of any matter
in connection with any phase of the Borrower's business or operations.

      Section 9.09 Marshalling; Recapture. No Secured Party shall be under any
obligation to marshal any assets in favor of the Borrower or any other party or
against or in payment of any or all of the Obligations. To the extent any
Secured Party receives any payment by or on behalf of the Borrower, which
payment or any part thereof is subsequently invalidated, declared to be
fraudulent or preferential, set aside or required to be repaid to the Borrower
or its estate, trustee, receiver, custodian or any other party under any
bankruptcy law, state or federal law, common law or equitable cause, then to
the extent of such payment or repayment, the obligation or part thereof which
has been paid, reduced or satisfied by the amount so repaid shall be reinstated
by the amount so repaid and shall be included within the liabilities of the
Borrower to such Secured Party as of the date such initial payment, reduction
or satisfaction occurred.

      Section 9.10 Independent Nature of Lenders' Rights. The amounts payable
at any time hereunder to each Lender shall be a separate and independent debt,
and, except as otherwise provided in any Financing Document, each Lender shall
be entitled to protect and enforce its rights arising our of this Agreement,
and it shall not be necessary for any other Lender to be joined as an
additional party in any proceeding for such purpose.

      Section 9.11 Counterparts. This Agreement may be executed in any number
of counterparts and by the different parties hereto in separate counterparts,
each of which when so executed and delivered shall be an original, but all of
which shall together constitute one and the same instrument.

      Section 9.12 Effectiveness. This Agreement shall become effective as of
the date hereof; provided, that, all of the parties hereto shall have signed a
copy hereof (whether the same or different copies) and shall have delivered the
same to the Administrative Agent pursuant to Section 9.01 or, in the case of
the Lenders, shall have given to the Administrative Agent written, telecopied
or telex notice (actually received) at such office that the same has been
signed and mailed to it.

      Section 9.13 Survival of Indemnities and Representations and Warranties.
All indemnities set forth herein and all representations and warranties made
herein and in any document, certificate or statement delivered pursuant hereto
or in connection herewith shall survive the execution and delivery of this
Agreement, the

                                      110

<PAGE>   117

Notes, the Letters of Credit and the other Financing Documents and the making
and repayment of the Loans and the expiration or cancellation of all Letters of
Credit.

      Section 9.14 Severability. In case any provision in or obligation under
this Agreement or the Notes or the other Financing Documents shall be invalid,
illegal or unenforceable in any jurisdiction, the validity, legality and
enforceability of the remaining provisions or obligations, or of such provision
or obligation in any other jurisdiction, shall not in any way be affected or
impaired thereby.

      Section 9.15 Headings Descriptive. The headings of the several sections
and subsections of this Agreement, and the Table of Contents, are inserted for
convenience only and shall not in any way affect the meaning or construction of
any provision of this Agreement.

      Section 9.16 Limitation of Recourse. The obligations of the Borrower
hereunder and under the other Financing Documents are obligations solely of the
Borrower and shall not constitute a debt or obligation of any direct or
indirect partner or shareholder of the Borrower or any of their respective
directors, officers, agents or employees (each such Person, a "Non-Recourse
Party"). No Non-Recourse Party shall be liable for any amount payable by the
Borrower under this Agreement or the other Financing Documents, and the Secured
Parties shall not seek a money judgment or deficiency or personal judgment
against any Non-Recourse Party for payment of the indebtedness payable by the
Borrower evidenced by this Agreement or the other Financing Documents. No
property or assets of any Non-Recourse Party, other than as provided in the
Financing Documents, shall be sold, levied upon or otherwise used to satisfy
any judgment rendered in connection with any action brought against the
Borrower with respect to this Agreement or the other Financing Documents. The
foregoing acknowledgments, agreements and waivers shall be enforceable by any
Non-Recourse Party. Notwithstanding the foregoing, nothing in this Section
shall limit or affect or be construed to limit or affect the obligations and
liabilities of any Credit Party or any other Non-Recourse Party (a) in
accordance with the terms of any Transaction Document or Financing Document
creating such liabilities and obligations to which such Credit Party or
Non-Recourse Party is a party, (b) arising from liability pursuant to
applicable Requirements of Law for such Credit Party's or such Non-Recourse
Party's fraudulent actions, knowing misrepresentations or willful misconduct or
(c) with respect to amounts distributed to it in violation of Section 6.10
hereof.

      Section 9.17 Confidentiality. Each party hereto will treat as
confidential the data and information in their possession regarding the
Portfolio Assets, the Transaction Documents and each other party hereto
(including any Affiliate of such other party), unless such data or information
(i) was disclosed to the receiving party without violating a confidentiality
obligation, (ii) was in the public domain, or (iii) is required to be disclosed
by law. In addition, each party may disclose confidential information to its
Affiliates or its technical, financial and legal advisors on a need-to-know
basis, provided such party agrees that it will not disclose such information to
third parties, or in

                                      111

accordance with governmental, administrative or judicial requirements to which

such attorney-in-fact shall deem expedient to prevent any impairment of the

and things performed or done by the Administrative Agent as the Borrower's
attorney-in-fact or any of its representatives in each case pursuant to the
powers granted hereunder.

                  This special power of attorney shall be deemed coupled with
an interest, and cannot be revoked by the Borrower until no Lender shall have
any Commitment outstanding and until the Notes, together with interest, and all
other Obligations are indefeasibly paid in full.

Borrower shall abstain from exercising any rights under any of the Assigned
Agreements which shall be inconsistent with the exercise of the rights and
functions herein granted to the Administrative Agent as the attorney-in-fact,
including abstaining from collecting, claiming and receiving any monies under

Borrower from, except during the exercise by the Administrative Agent of any
such rights and functions, exercising such rights and undertaking the
Borrower's operations, in each case, in the ordinary course of business in
accordance with the Financing Documents and the Assigned Agreements. To the
extent that the Borrower shall receive any monies in respect thereof,
notwithstanding the provisions of this Section 2.02, the Borrower shall be
deemed to have received such funds for the account of the Administrative Agent
and shall hold the same in trust and promptly pay the same to the
Administrative Agent for deposit in the Revenue Account (or other account as
may be required or contemplated by the Deposit Account Agreement) and
application pursuant to the Deposit Account Agreement.

                  All reasonable costs, expenses, charges and fees paid or
incurred by the Administrative Agent in the exercise of any of the rights,
remedies or powers granted hereunder shall be for the account of the Borrower,
and the Borrower undertakes promptly on demand to pay same or, as the case may
be, to reimburse the Administrative Agent and/or its agents, representatives,
successors and assignees as the case may be, for any monies paid by it with
interest thereon at the Default Rate from the date the same shall have been
paid by the Administrative Agent and/or its agents, representatives, successors
and assigns until actually paid by the Borrower to the extent that there are
then insufficient funds available in the Revenue Account for this purpose.

COVENANTS.

                  The Borrower represents, warrants and covenants, which

the law of any jurisdiction) or statements relating to the Assignment Revenues
or the Assignment Collateral, except financing statements filed or to be filed

records of the Borrower relating thereto are, and will continue to be, kept at
the locations disclosed in Schedule 1, or at such new locations as the Borrower
may establish in accordance with Section 3.04(b). All Receivables, General
Intangibles and Contract Rights of the Borrower are, and will continue to be,

deemed to have represented and warranted, to the knowledge of the Borrower and
unless otherwise promptly disclosed by the Borrower in writing to the
Administrative Agent upon the Borrower obtaining actual knowledge thereof, that

reasonable costs and expenses (including reasonable attorneys' fees) of
collection, whether incurred by the Borrower or the Administrative Agent, shall
be borne by the Borrower.

                  4.05     Modification of Terms, etc. Except as otherwise
provided in the Credit Agreement or as permitted in Section 4.06 hereof, (a)
the Borrower shall not rescind or cancel any Indebtedness in any fiscal year in
an amount, in the aggregate, in excess of $250,000 evidenced by any
Receivables, General Intangibles or Assigned Agreements, or modify in any
manner adverse to the Borrower or the Secured Parties any material term
thereof, or make any adjustment adverse to the Borrower or the Secured Parties
with respect thereto, or grant any extension for performance of the same, or
compromise or settle any dispute, claim, suit or legal proceeding relating
thereto, or sell any Receivable, General Intangible or Assigned Agreements, or
interest therein, without the prior written consent of the Administrative
Agent, which consent the Administrative Agent will not unreasonably withhold,
delay or condition, and (b) the Borrower will duly fulfill all material
obligations on its part to be fulfilled under or in connection with the
Receivables, the General Intangibles and the Assigned Agreements and will do
nothing to impair the security interests of the Administrative Agent
(including, without limitation, the creation, attachment and priority thereof)
in the Receivables, the General Intangibles or the Assigned Agreements.

                  4.06     Collection. The Borrower shall endeavor to cause to
be collected from the account debtor named in the Borrower's Receivables and
General Intangibles or obligor under any Assigned Agreements, and paid by such
account debtor directly to the Revenue Account, as and when due (including,
without limitation, amounts which are delinquent, such amounts to be collected
in accordance with generally accepted lawful collection procedures) any and all
amounts owing under or on account of such Receivable, General Intangible or
Assigned Agreements, and apply forthwith upon receipt thereof all such amounts
as are so collected to the

                                       14

<PAGE>   141

outstanding balance of such Receivable, General Intangible or under such
Assigned Agreements, except that, unless an Event of Default shall have
occurred and be continuing (and shall not have been waived by an appropriate
vote or other action by the Required Lenders), the Borrower may allow in the
ordinary course of business as adjustments to amounts owing under the
Borrower's Receivables, General Intangibles and Assigned Agreements an
extension or renewal of the time or times of payment, or settlement for less
than the total unpaid balance, which the Borrower finds appropriate to enhance
collectibility in accordance with sound business judgment. During any period
when any Obligations remain outstanding, the reasonable costs and expenses
(including, without limitation, reasonable attorneys fees) of collection of the
Borrower's Receivables, General Intangibles and Assigned Agreements, whether
incurred by the Borrower or the Administrative Agent, shall be borne by the
Borrower.

                  SECTION 5.        SPECIAL PROVISIONS CONCERNING PATENTS,
COPYRIGHTS AND TRADEMARKS.

                  5.01     Infringements. Promptly upon obtaining actual
knowledge thereof, the Borrower shall notify the Administrative Agent and the
Lenders in writing of all pertinent details available to it, with respect to
any infringement or other violation of the Borrower's rights in, or any claim
of any such infringement of, any, Patent, Copyright or Trademark, whether or
not such right is presently held by the Borrower or third party. As to each
such instance, absent the Required Lenders' authorization to proceed otherwise,
which authorization shall not be unreasonably withheld, delayed or conditioned,
and to the extent permitted by applicable Requirements of Law, the Borrower
shall use commercially reasonable efforts to pursue a remedy.

                  5.02     Other Patents, Copyrights and Trademarks. If the
Borrower hereafter acquires rights in any Patent, Copyright or Trademark, the
Borrower shall deliver to the Administrative Agent and the Lenders within 30
days, a copy of such Patent, Copyright or Trademark and a first priority
perfected security interest therein or a collateral assignment thereof, as
appropriate.

                  5.03     Remedies. If an Event of Default shall occur and be
continuing (and shall not have been waived by an appropriate vote or other
action by the Lenders), the Administrative Agent, acting pursuant to and in
accordance with the terms of the Deposit Account Agreement, the other Financing
Documents and applicable Requirements of Law may (a) declare the entire right,
title, and interest of the Borrower in any Patents, Copyrights and Trademarks
vested in the Administrative Agent, in which event such right, title, and
interest immediately shall vest in the Administrative Agent; and (b) take and
practice or use or sell any or all of such Patents, Copyrights or Trademarks,
or take and use or sell the Borrower's rights in such Patents, Copyrights or
Trademarks, along with the goodwill and all other elements of the Borrower's
ongoing business symbolized by such assets and secured under this Agreement,
and the right to carry on the business of the Borrower in connection with which
such assets have been used. The Borrower shall execute any other and further
documents which the Administrative Agent may request further to confirm the
foregoing and to transfer to the Administrative Agent ownership of the
Borrower's rights to such Trademarks, Patents and/or Copyrights.

                                       15

                  SECTION 6.        PROVISIONS CONCERNING ALL ASSIGNMENT
REVENUES AND ASSIGNMENT COLLATERAL; INSURANCE.

                  6.01     Protection of the Administrative Agent's Interests.
The Borrower will do nothing to impair the rights of the Administrative Agent
or the Lenders in the Assignment Revenues and the Assignment Collateral,
provided, however, that nothing herein shall prevent the Borrower, prior to the
exercise by the Administrative Agent of any such rights, from undertaking the
Borrower's operations in the ordinary course of business in accordance with the
Assigned Agreements. The Borrower assumes all liability and responsibility in
connection with the Assignment Revenues and the Assignment Collateral and the
liability of the Borrower with respect to the Secured Obligations shall in no
way be affected or diminished by reason of the fact that such Assignment
Revenues and Assignment Collateral may be lost, destroyed, stolen, damaged or
for any reason whatsoever unavailable to the Borrower.

                  6.02     Further Actions. The Borrower will, at its own
expense, make, execute, endorse, acknowledge, file and/or deliver to the
Administrative Agent and the Lenders from time to time such lists, descriptions
and designations of the Assignment Revenues and the Assignment Collateral,
warehouse receipts, receipts in the nature of warehouse receipts, bills of
lading, documents of title, vouchers, invoices, schedules, confirmatory
assignments, conveyances, financing statements, transfer endorsements, powers
of attorney, certificates, reports and other assurances or instruments and take
such further steps relating to the Assignment Revenues and the Assignment
Collateral and other property or rights covered by the interests hereby
granted, which are necessary to perfect, preserve or protect its ownership and
security interests in the Assignment Revenues and the Assignment Collateral or
is otherwise reasonably requested by the Administrative Agent; provided, that
the foregoing shall not require the Borrower to obtain any Additional Contract
Consent except as expressly required by Section 5.22 of the Credit Agreement.

                  6.03     Financing Statements. The Borrower agrees to assign
and deliver to the Administrative Agent, on behalf of the Lenders, such
financing statements (or similar statement or instrument of registration under
the law of any jurisdiction), in form reasonably acceptable to the
Administrative Agent as it may from time to time reasonably request or as are
necessary or desirable in their reasonable opinion to establish and maintain
the security interests contemplated hereunder as valid, enforceable, first
priority security interests as provided herein and the other rights and
security contemplated herein, all in accordance with the Uniform Commercial
Code as enacted in any and all relevant jurisdictions or any other Requirement
of Law. The Borrower will pay any applicable filing fees and related expenses.
The Borrower authorizes the Administrative Agent to file any such financing
statements without the signature of the Borrower to the extent permitted under
applicable Requirements of Law.

                  SECTION 7.        REMEDIES UPON OCCURRENCE OF EVENT OF
DEFAULT.

                  7.01     Remedies; Obtaining the Assignment Collateral Upon
Default. The Borrower agrees that, if any Event of Default shall have occurred
and be continuing (and shall not have been waived by an appropriate vote or
other action by the Required Lenders), then and

                                       16

<PAGE>   143

in every such case, subject to the terms and provisions of the Credit Agreement
and this Agreement and any Requirement of Law then in effect, the
Administrative Agent, in addition to any rights now or hereafter existing under
any Requirement of Law, shall have all rights as a secured creditor under the
Uniform Commercial Code or any other Requirement of Law in all relevant
jurisdictions and may, acting pursuant to and in accordance with the terms of
the Credit Agreement and this Agreement:

                  (a) personally, or by agents or attorneys, immediately retake
possession of the Assignment Collateral or any part thereof, from the Borrower
or any other Person who then has possession of any part thereof with or without
notice or process of law, and for that purpose may enter upon the Borrower's
premises where any of the Assignment Collateral is located and remove the same
and use in connection with such removal any and all services, supplies, aids
and other facilities of the Borrower; and

                  (b) instruct the obligor or obligors on any agreement,
instrument or other obligation (including, without limitation, any other
Assigned Agreement, the General Intangibles and the Receivables) constituting
the Assignment Revenues and Assignment Collateral to make any payment required
by the terms of such instrument or agreement directly to the Administrative
Agent for deposit in the Revenue Account (or any other account required or
contemplated by the Deposit Account Agreement) and application pursuant to the
Deposit Account Agreement; and

                  (c) apply all monies, securities and instruments in the
Revenue Account, and each other Account, in accordance with the Deposit Account
Agreement; and

                  (d) sell, assign or otherwise liquidate, or direct the
Borrower to sell, assign or otherwise liquidate, any or all of the Assignment
Collateral or any part thereof, and take possession of the proceeds of any such
sale or liquidation for deposit in the Revenue Account (or any other account
required or contemplated by the Deposit Account Agreement) and application
pursuant to the Deposit Account Agreement; and

                  (e) take possession of the Assignment Collateral or any part
thereof, by directing the Borrower in writing to deliver the same to the
Administrative Agent at any place or places reasonably designated by the
Administrative Agent, in which event the Borrower shall at its own expense:

                           (i)      forthwith cause the same to be moved to the
                  place or places so designated by the Administrative Agent and
                  there delivered to the Administrative Agent;

                           (ii)     store and keep any Assignment Collateral so
                  delivered to the Administrative Agent (to the extent not
                  physically delivered to the Administrative Agent) at such
                  place or places pending further action by the Administrative
                  Agent as provided in Section 7.02; and

                                       17

<PAGE>   144

                           (iii)    while such Assignment Collateral shall be
                  so stored and kept, provide such guards and maintenance
                  services as shall be necessary to protect the same and to
                  preserve and maintain them in good condition;

     it being understood that the Borrower's obligation to so deliver the
     Assignment Collateral is of the essence of this Agreement and that,
     accordingly, upon application to a court of equity having jurisdiction,
     the Administrative Agent shall be entitled to a decree requiring specific
     performance by the Borrower of such obligation.

                  7.02     Remedies, Disposition of the Assignment Collateral.
Any Assignment Collateral repossessed by the Administrative Agent under or
pursuant to Section 7.01, and any other Assignment Collateral whether or not so
repossessed by the Administrative Agent, may be sold, assigned, leased or
otherwise disposed of under one or more contracts or as an entirety, and
without the necessity of gathering at the place of sale the property to be
sold, and in general in such manner, at such time or times, at such place or
places and on such terms as the Administrative Agent, acting in good faith,
may, upon written direction in compliance with any Requirement of Law,
determine to be commercially reasonable. Subject to the foregoing, any of the
Assignment Collateral may be sold, leased or otherwise disposed of, in the
condition in which the same existed when taken by the Administrative Agent or
after any overhaul or repair which the Administrative Agent, acting in good
faith, shall determine to be commercially reasonable. Any such disposition
which shall be a private sale or other private proceeding permitted by such
requirements shall be made upon not less than 10 days' written notice to the
Borrower specifying the time at which such disposition is to be made and the
intended sale price or other consideration therefor, and shall be subject, for
the 10 days after the giving of such notice, to the right of the Borrower or
any nominee of the Borrower to acquire the Assignment Collateral involved at a
price or for such other consideration at least equal to the intended sale price
or other consideration so specified. To the extent permitted by Requirements of
Law, the Administrative Agent on behalf of the Lenders may bid for and become
the purchaser of the Assignment Collateral or any item thereof, offered for
sale in accordance with this Section 7.02. If, under mandatory requirements of
any Requirement of Law, the Administrative Agent shall be required to make
disposition of the Assignment Collateral within a period of time which does not
permit the giving of notice to the Borrower as hereinabove specified, the
Administrative Agent need give the Borrower only such notice of disposition as
shall be reasonably practicable in view of such mandatory requirements of any
Requirement of Law.

                  The Borrower hereby irrevocably appoints the Administrative
Agent as its attorney-in-fact, so that the Administrative Agent, or any Person
empowered by the Administrative Agent, shall be authorized to sell, assign,
lease or otherwise dispose of the Assignment Collateral or any part thereof
pursuant to the provisions of the preceding paragraph, and, in general, to do
or cause to be done all such acts and things which are otherwise required to be
done by the Borrower under this Agreement.

                  7.03     Waiver of Claims. Except as otherwise provided in
this Agreement or in any other Financing Document, THE BORROWER HEREBY WAIVES,
TO THE EXTENT PERMITTED BY APPLICABLE REQUIREMENTS OF LAW, NOTICE AND JUDICIAL

                                       18

<PAGE>   145

HEARING IN CONNECTION WITH THE ADMINISTRATIVE AGENT TAKING POSSESSION OR THE
ADMINISTRATIVE AGENT'S DISPOSITION OF ANY OF THE ASSIGNMENT COLLATERAL, IN EACH
CASE AS PERMITTED BY APPLICABLE REQUIREMENTS OF LAW, INCLUDING, WITHOUT
LIMITATION, ANY AND ALL PRIOR NOTICE AND HEARING FOR ANY PREJUDGMENT REMEDY OR
REMEDIES AND ANY SUCH RIGHT WHICH THE BORROWER WOULD OTHERWISE HAVE UNDER THE
CONSTITUTION OR ANY STATUTE OF THE UNITED STATES OR ANY POLITICAL SUBDIVISION
OF ANY SUCH JURISDICTION, and the Borrower hereby further waives, to the extent
permitted by Requirements of Law:

                           (i)   all damages occasioned by such taking of
                  possession except any damages which are the direct result of
                  the gross negligence or willful misconduct of the
                  Administrative Agent, any Lender, or any Person acting on its
                  behalf or instruction;

                           (ii)  all other requirements as to the time, place
                  and terms of sale or other requirements with respect to the
                  enforcement of the Administrative Agent's rights hereunder;
                  and

                           (iii) all rights of redemption, appraisement,
                  valuation, stay, extension or moratorium now or hereafter in
                  force under any Requirements of Law in order to prevent or
                  delay the enforcement of this Agreement (including, without
                  limitation, any right to claim that such enforcement should
                  be stayed pending the outcome of any other action or
                  proceeding (including any arbitration proceeding)) or the
                  absolute sale of the Assignment Collateral or any portion
                  thereof, and the Borrower, for itself and all who may claim
                  under it, insofar as it or they now or hereafter lawfully
                  may, hereby waives the benefit of all such Requirements of
                  Law.

To the extent permitted under Requirements of Law, any sale of, or the grant of
options to purchase, or any other realization upon, any Assignment Collateral
shall operate to divest all right, title, interest, claim and demand, either at
law or in equity, of the Borrower therein and thereto, and shall be a perpetual
bar both at law and in equity against the Borrower and against any and all
Persons claiming or attempting to claim the Assignment Collateral so sold,
optioned or realized upon, or any part thereof, from, through and under the
Borrower.

                  7.04     Application of Proceeds. The Proceeds of any
Assignment Collateral obtained or disposed of pursuant to this Agreement,
including Sections 7.01 and 7.02 shall be applied in accordance with the
Deposit Account Agreement.

         For the avoidance of doubt, it is understood that the Borrower shall
remain liable to the extent of any deficiency between the amount of the
Proceeds of the Assignment Collateral and the aggregate amount of the Secured
Obligations.

                                       19

<PAGE>   146

                  7.05     Remedies Cumulative. No failure or delay on the part
of the Administrative Agent or any Lender in exercising any right, power or
privilege hereunder or under any other Financing Document and no course of
dealing between the Borrower and the Administrative Agent or any Lender shall
operate as a waiver thereof; nor shall any single or partial exercise of any
right, power or privilege hereunder or under any other Financing Document
preclude any other or further exercise thereof or the exercise of any other
right, power or privilege hereunder or thereunder. The rights, powers and
remedies herein or in any other Financing Document expressly provided are
cumulative and not exclusive of any rights, powers or remedies which the
Administrative Agent or any Lender would otherwise have. No notice to or demand
on the Borrower in any case shall entitle the Borrower to any other or further
notice or demand in similar or other circumstances or constitute a waiver of
the rights of the Administrative Agent or any Lender to any other or further
action in any circumstances without notice or demand.

                  7.06     Discontinuance of Proceedings. In case the
Administrative Agent shall have instituted any proceeding to enforce any right,
power or remedy under this Agreement by foreclosure, sale, entry or otherwise,
and such proceeding shall have been discontinued or abandoned for any reason or
shall have been determined adversely to the Administrative Agent, then and in
every such case the Borrower, the Administrative Agent and each holder of any
of the Obligations shall be restored to their former positions and rights
hereunder with respect to the Assignment Collateral subject to the security
interest created under this Agreement, and all rights, remedies and powers of
the Administrative Agent shall continue as if no such proceeding had been
instituted.

                  7.07     Grant of License or Sub-License to Use Patent,
Trademark, Copyright and License Collateral. For the purpose of enabling the
Administrative Agent to exercise rights and remedies under this Article VII at
such time as the Administrative Agent shall be lawfully entitled to exercise
such rights and remedies, the Borrower hereby grants to Administrative Agent an
irrevocable, non-exclusive license (exercisable without payment of royalty or
other compensation to the Borrower) to use, license or sub-license any Patent,
Trademark, Copyright or License (to the extent the Borrower has authority to
sub-license any such Patent, Trademark, Copyright or License) now owned or
licensed or hereafter acquired or licensed by the Borrower, and wherever the
same may be located, and including in such license reasonable access to all
media in which any of the licensed items may be recorded or stored and to all
computer software and programs used for the compilation or printout thereof.
The use of such license or sub-license by the Administrative Agent shall be
exercised, at the option of the Administrative Agent, only upon the occurrence
and during the continuation of an Event of Default; provided that any license,
sub-license or other transaction entered into by the Administrative Agent in
accordance herewith shall be binding upon the Borrower notwithstanding any
subsequent cure of an Event of Default. The Administrative Agent agrees to
apply the net Proceeds received from any such license as provided in Section
7.04 hereof.

                  SECTION 8.        INDEMNITY; EXPENSES.

                                       20

<PAGE>   147

                  (a) Borrower agrees to indemnify and hold harmless the
Administrative Agent and each Secured Party from and against any and all
claims, losses and liabilities arising out of or resulting from the Collateral
or Borrower's pledge and assignment under this Agreement (including, without
limitation, enforcement against Borrower of this Agreement), except claims,
losses or liabilities resulting from the gross negligence or willful misconduct
of any Secured Party or any other Person designated by any Secured Party to act
on its behalf pursuant to this Agreement.

                  (b) Borrower will upon demand pay to the Administrative Agent
or any Secured Party the amount of any and all reasonable expenses, including
the reasonable fees and expenses of its counsel and of any experts and agents,
which the Administrative Agent or any Secured Party may incur in connection
with (i) the administration of this Agreement, (ii) the sale of, collection
from, or other realization upon, any of the Collateral of the Borrower, (iii)
the exercise or enforcement (whether through negotiations, legal proceedings or
otherwise) of any of the rights of the Administrative Agent or any Secured
Party hereunder against Borrower or (iv) the failure by Borrower to perform or
observe any of the provisions hereof.

                  SECTION 9.        MISCELLANEOUS.

                  9.01     Notices. All notices hereunder, unless otherwise
specified, shall be provided as specified in Section 9.01 of the Credit
Agreement. Promptly after the execution of any and all amendments, supplements
and waivers, of and to the Assignment Revenues or Assignment Collateral,
originals, if reasonably available and, if not, copies of such amendments,
supplements and waivers shall be delivered to the Administrative Agent. The
Administrative Agent shall not be required to give its prior consent to any
such amendments, supplements or waivers unless the same affects the
Administrative Agent's duties or liabilities.

                  9.02     Waiver, Amendment. No amendment or waiver of any
provision of this Agreement shall be effective unless the same shall be
undertaken and accomplished in accordance with the requirements of Section 9.02
of the Credit Agreement. No delay on the part of any Secured Party in the
exercise of any right, power or remedy shall operate as a waiver thereof, nor
shall any single or partial waiver by such Secured Party of any right, power or
remedy preclude any further exercise thereof, or the exercise of any other
right, power or remedy.

                  9.03     Obligations Absolute. The obligations of the
Borrower under this Agreement shall be absolute and unconditional and shall
remain in full force and effect until termination pursuant to Section 9.08 and
shall not be otherwise released, suspended, discharged, terminated or affected
by, any circumstance or occurrence whatsoever, including, without limitation:
(i) any renewal, extension, amendment or modification of, or addition or
supplement to or deletion from, the Credit Agreement or any of the Financing
Documents or any other instrument or agreement referred to therein, or any
assignment or transfer of any thereof, (ii) any waiver, consent, extension,
indulgence or other action or inaction under or in respect of any such
instrument or agreement or this Agreement or any exercise or non-exercise of
any right, remedy, power or privilege under or in respect of this Agreement or
any other Financing Document; (iii) any furnishing of any additional security
(including, without limitation, any assets, whether now

                                       21

owned or hereafter acquired, upon which a Lien is created or granted from time
to time pursuant to the other Security Documents) to the Administrative Agent
or any acceptance thereof or any sale, exchange, release, surrender or
realization of or upon any security by the Administrative Agent; or (iv) any
invalidity, irregularity or unenforceability of all or part of the Secured
Obligations or of any security therefor. In the event of any inconsistency
between this Agreement and the Deposit Account Agreement, the Deposit Account
Agreement shall govern.

                  9.04     Successors and Assigns. This Agreement shall be
binding upon and inure to the benefit of and be enforceable by the respective
successors and assigns of the parties hereto and shall inure to the benefit of
the Lenders; provided, however, that the Borrower may not assign or transfer
any of its rights or obligations hereunder without the prior written consent of
the Administrative Agent and each of the Lenders. Any Lender may transfer,
assign or grant all or such relevant part of its rights hereunder in connection
with an assignment or transfer of all or any part of its interest in its Loans
in accordance with the provisions of the Credit Agreement. All agreements,
statements, representations and warranties made by the Borrower herein or in
any certificate or other instrument delivered by the Borrower or on its behalf
under this Agreement shall be considered to have been relied upon by the
Lenders and shall survive the execution and delivery of this Agreement, the
Credit Agreement and the other Financing Documents regardless of any
investigation made by the Lenders or on their behalf.

                  9.05     Headings Descriptive, etc. The headings of the
several sections and subsections of this Agreement are inserted for convenience

ANY APPEALS FROM THOSE COURTS MAY HAVE TO BE HEARD BY A COURT LOCATED OUTSIDE
OF NEW YORK, NEW YORK. THE BORROWER WAIVES IN ALL DISPUTES ANY OBJECTION THAT
IT MAY HAVE TO THE LOCATION OF THE COURT CONSIDERING THE DISPUTE INCLUDING,
WITHOUT LIMITATION, ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE
GROUNDS OF FORUM NON CONVENIENS.

                  (c) THE BORROWER AND THE SECURED PARTIES EACH WAIVE ANY RIGHT
TO HAVE A JURY PARTICIPATE IN RESOLVING ANY DISPUTE, WHETHER SOUNDING IN
CONTRACT, TORT, OR OTHERWISE ARISING OUT OF, CONNECTED WITH, RELATED TO OR
INCIDENTAL TO THE RELATIONSHIP ESTABLISHED BETWEEN THEM IN CONNECTION WITH THIS
AGREEMENT AND THE OTHER FINANCING DOCUMENTS. INSTEAD, ANY DISPUTES RESOLVED IN
COURT WILL BE RESOLVED IN A BENCH TRIAL WITHOUT A JURY.

                  9.07     The Borrower's Duties. It is expressly agreed,
anything herein contained to the contrary notwithstanding, that the Borrower
shall remain liable to perform all of the obligations, if any, assumed by it
with respect to the Assignment Revenues or the Assignment Collateral and the
Administrative Agent and the Lenders shall have no obligations or liabilities
with respect to any Assignment Revenues or Assignment Collateral by reason of
or arising out of or in connection with this Agreement, nor shall the
Administrative Agent or the Lenders be required or obligated in any manner to
perform or fulfill any of the obligations of the Borrower under or with respect
to any Assignment Revenues or Assignment Collateral.

                  9.08     Termination; Release. This Agreement shall terminate
when all Secured Obligations have been indefeasibly paid in full and all
Commitments have been terminated, and the Administrative Agent, at the written
request and expense of the Borrower, will promptly execute and deliver to the
Borrower the proper instruments (which may include Uniform Commercial Code
termination statements on form UCC-3) acknowledging the termination of this
Agreement, and will promptly duly assign, transfer and deliver to the Borrower
(without recourse and without any representation or warranty) free from any
interest of the Administrative Agent or Lien granted hereunder such of the
Assignment Revenues or Assignment Collateral as may be in possession of the
Administrative Agent and has not theretofore been sold or otherwise applied or
released pursuant to this Agreement together with such notices to third parties
as may be necessary to countermand any notices previously sent to them pursuant

                  9.09     Counterparts. This Agreement may be executed in any
number of counterparts and by the different parties hereto on separate
counterparts, each of which when so

                                       23

executed and delivered shall be an original, but all of which shall together
constitute one and the same instrument.

                  9.10     Applicability of Deposit Account Agreement. In
amplification of, and notwithstanding any other provisions of this Agreement,
in connection with its obligations hereunder, the Administrative Agent shall
have all of the rights, powers, privileges, exculpations, protections and
indemnities as are provided for or referred to in the Deposit Account
Agreement.

                  9.11     Limitation of Recourse. The obligations of the
Borrower hereunder are obligations solely of the Borrower and shall not
constitute a debt or obligation of any direct or indirect, partner or
shareholder of the Borrower or any of their respective directors, officers,
agents or employees (each such Person, a "Non-Recourse Party"). No Non-Recourse
Party shall be liable for any amount payable by the Borrower under this
Agreement and the Secured Parties shall not seek a money judgment or deficiency
or personal judgment against any Non-Recourse Party for payment of the
indebtedness payable by the Borrower evidenced by this Agreement. No property
or assets of any Non-Recourse Party, other than as provided in the Financing
Documents, shall be sold, levied upon or otherwise used to satisfy any judgment
rendered in connection with any action brought against the Borrower with
respect to this Agreement or the other Financing Documents. The foregoing
acknowledgments, agreements and waivers shall be enforceable by any
Non-Recourse Party. Notwithstanding the foregoing, nothing in this Section
shall limit or affect or be construed to limit or affect the obligations and
liabilities of any Credit Party or any other Non-Recourse Party (a) in
accordance with the terms of any Transaction Document or Financing Document
creating such liabilities and obligations to which such Credit Party or
Non-Recourse Party is a party, (b) arising from liability pursuant to
applicable Requirement of Law for such Credit Party's or such Non-Recourse
Party's fraudulent actions, knowing misrepresentations or willful misconduct or
(c) with respect to amounts distributed to it in violation of Section 6.10 of
the Credit Agreement.

         WHEREAS, the Credit Agreement contemplates the execution, delivery and

facilities and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, Pledgor hereby agrees as follows:

         SECTION 2. Pledge; Assignment; Grant of Security Interest. Pledgor
hereby pledges, hypothecates and assigns to the Administrative Agent, and hereby
grants to the Administrative Agent for the benefit of the Secured Parties, a
pledge and assignment of, and a security interest in, all of its right, title
and interest in and to the following (the "Collateral"):

         (a)      All general and limited partnership interests now owned or
hereafter acquired by Pledgor in and to the Borrower (the "Partnership
Interests") and the partnership agreement relating to the Borrower (the
"Partnership Agreement") and all rights related thereto, including, without
limitation, (i) all rights of Pledgor as a general or limited partner, as the
case may be, and all rights to receive distributions, cash, instruments and
other property from time to time receivable or otherwise distributable in
respect of any Partnership Interests or pursuant to the Partnership Agreement,
(ii) all rights of Pledgor to receive proceeds of any insurance, indemnity,
warranty or guaranty with respect to any Partnership Interests or the

notwithstanding, (a) Pledgor shall remain liable under the Partnership Agreement
and the other contracts and agreements included in the Collateral to the extent
set forth therein to perform all of its duties and obligations thereunder to the
same extent as if this Agreement had not been executed, (b) the exercise by any
Secured Party of any of the rights hereunder shall not release Pledgor from any
of its duties or obligations under the contracts and agreements included in the
Collateral and (c) neither the Administrative Agent nor any Secured Party shall
have any obligation or liability under the contracts and agreements included in
the Collateral or otherwise by reason of this

                                       2

Agreement, nor shall the Administrative Agent or any Secured Party be obligated
to perform any of the obligations or duties of Pledgor thereunder or to take any
action to collect or enforce any claim assigned hereunder.

         SECTION 5. Delivery of Collateral. All certificates or instruments
representing or evidencing the Collateral at any time shall be delivered to and
held by or on behalf of the Administrative Agent pursuant hereto and shall be in
suitable form for transfer by delivery, or shall be accompanied by duly executed
instruments of transfer or assignment in blank, all in form and substance
satisfactory to the Administrative Agent. The Administrative Agent shall have
the right, upon the occurrence and continuance of an Event of Default, in its
discretion and without notice to Pledgor, to transfer to or to register in the
name of the Administrative Agent or any of its nominees any or all of the
Collateral, subject only to compliance with Requirements of Law, the terms and
conditions of the Credit Agreement and the revocable rights specified in Section

certificates or instruments of smaller or larger denominations.

         SECTION 6. No Subrogation. Pledgor shall not exercise any rights which
it may acquire by way of subrogation under this Agreement, by any payments made
hereunder or otherwise, until all Secured Obligations shall have been
indefeasibly paid in full and all Commitments have been terminated. If any
amount shall be paid to Pledgor on account of such subrogation rights at any
time when all Secured Obligations shall not have been indefeasibly paid in full
(whether pursuant to a claim in any bankruptcy or similar proceeding or
otherwise) or when any Commitment shall remain outstanding, such amount shall be
held in trust for the benefit of the Administrative Agent and the Secured
Parties and shall forthwith be paid to the Administrative Agent to be credited
and applied to the Secured Obligations, whether matured or unmatured, in
accordance with Section 17.

         SECTION 7. Reinstatement. This Agreement shall continue to be
effective, or be reinstated, as the case may be, if at any time payment, or any
part thereof, of any of the Secured Obligations is rescinded or must otherwise
be restored or returned by any Secured Party upon the insolvency, bankruptcy,
dissolution, liquidation or reorganization of Pledgor, or upon or as a result of
the appointment of a receiver, intervenor or conservator of, or trustee or
similar officer for, Pledgor or any substantial part of its property, or
otherwise, all as though such payments had not been made.

         SECTION 8. Representations and Warranties. Pledgor represents and
warrants as follows:

         (a)      Pledgor (i) is duly formed, validly existing and in good
standing under the laws of the State of Delaware, (ii) has all requisite power
and authority to own its property and assets, to borrow money and to transact
the business in which it is presently engaged and in which it proposes to be
engaged, (iii) has duly qualified and is authorized to do business and is in
good standing in every jurisdiction where the character of its properties or the
nature of its activities makes such qualification necessary and (iv) is in full
compliance with its Governing Documents, all material Contractual Obligations,
all applicable material Requirements of Law and all

                                       3

material Governmental Approvals. As of the date hereof, (x) Pledgor is the sole
General Partner of the Borrower and (y) the Borrower has no Subsidiaries.

         (b)      The execution, delivery and performance by Pledgor of this
Agreement and the consummation of the transactions contemplated hereby (i) are
within its powers, (ii) have been duly authorized by all necessary corporate
action, (iii) do not and will not contravene (A) its Governing Documents or (B)
any material Requirement of Law, any material Contractual Obligation or any
material Governmental Approval binding on or affecting it and (iv) does not and
will not conflict with or be inconsistent with or result in any breach of any of
the material terms, covenants, conditions or provisions of, or constitute a
default under, or result in the creation or imposition of (or the obligation to
create or impose) any Lien (except Permitted Liens) upon any of its properties
or assets pursuant to, the terms of any material Contractual Obligation binding
on or affecting it.

         (c)      Pledgor has duly executed and delivered this Agreement and
this Agreement constitutes the legal, valid and binding obligation of Pledgor,
enforceable against Pledgor in accordance with its terms, except as enforcement
thereof may be subject to (i) the effect of any applicable bankruptcy,
insolvency, reorganization, moratorium or similar laws affecting creditors'
rights generally and (ii) general principles of equity.

         (d)      No Governmental Approval or approval of any other Person
(except such as have been duly obtained, made or given, and are in full force
and effect) is required to authorize, or is required in connection with (i) the
execution, delivery or performance of this Agreement by Pledgor or the
consummation of any of the transactions contemplated hereby, (ii) the legality,
validity, binding effect or enforceability of this Agreement or the perfection
and maintenance of the security interest created hereby (including the first
priority nature of such security interest) or (iii) for the exercise by the
Administrative Agent of the voting or other rights provided for in this
Agreement or the remedies in respect of the Collateral pursuant to this
Agreement. All applicable waiting periods relating to any such Governmental
Approval or other approval which are required and have been obtained have
expired without any adverse action taken with respect thereto.

         (e)      The Partnership Agreement, a true and complete copy of which
has been furnished to the Administrative Agent, has been duly authorized,
executed and delivered by Pledgor and is in full force and effect and is binding
upon and enforceable against Pledgor in accordance with its terms. There exists
no default under the Partnership Agreement.

         (f)      This Agreement creates a valid security interest in the
Collateral purported to be pledged and assigned by Pledgor hereunder securing
the payment of the Secured Obligations.

         (g)      Upon the filing of the financing statements (the "Financing
Statements") referenced in

         (h)      I hereof under the Uniform Commercial Code as in effect in the
State of Delaware (the "Delaware UCC"), the security interest is created hereby
shall be perfected under the Delaware UCC, to the extent that the Collateral
constitutes "general intangibles" (as defined in the Delaware UCC) and no
further filings or other actions are necessary to perfect such security

                                       4
<PAGE>   164

interest. Upon filing of such Financing Statements pursuant to the Delaware UCC,
such security interests, as so perfected, are first priority security interests.

         (i)      When any certificates or instruments evidencing the Collateral
shall be delivered hereunder, and for so long as such certificates or
instruments shall remain in the possession of the Administrative Agent in the
State of New York or the State of North Carolina, the security interest in such
Collateral created hereby shall be perfected under the Uniform Commercial Code
as in effect in the State of New York (the "NY UCC") or the State of North
Carolina, as applicable, and such security interest, as so perfected, will be a
first priority security interest.

         (j)      The security interest created by this Agreement in the
Collateral described in clause (a) of Section 1 hereof has been registered in
the name of the Administrative Agent in the register maintained for such purpose
at the chief executive office and principal place of business of the Borrower
and, to the extent that such Collateral constitutes "uncertificated securities"
(as defined in the Delaware UCC), such security interest is perfected under the
Delaware UCC and, as so perfected, is a first priority security interest.

         (k)      The chief place of business and chief executive office of
Pledgor and the office where Pledgor keeps its records concerning the Collateral
is set forth under its name on the signature page hereof.

         (l)      Pledgor is the legal and beneficial owner of the Collateral
purported to be pledged and assigned by it hereunder, free and clear of any
Lien, other than Permitted Liens. No effective financing statement or other
instrument similar in effect covering all or any part of such Collateral has
been executed or authorized by Pledgor or, is on file in any recording office,
except such as may have been filed in favor of the Administrative Agent relating
to this Agreement. Pledgor has no trade name.

         (m)      There are no conditions precedent to the effectiveness of this
Agreement that have not been satisfied or waived.

         (n)      No part of the Collateral is subject to the terms of any
agreement restricting the sale or transfer of such Collateral, except for the
Partnership Agreement and the Financing Documents.

         (o)      There is no (i) injunction, writ, preliminary restraining
order or order of any nature issued by an arbitrator, court or other
Governmental Authority against Pledgor in connection with the transactions
provided for herein, or (ii) action, suit, arbitration, litigation,
investigation or proceeding of or before any arbitrator or Governmental
Authority pending against Pledgor or, to Pledgor's knowledge, threatened against
Pledgor which would reasonably be expected to materially adversely affect the
right or ability of Pledgor to fulfill its obligations under this Agreement.

         (p)      Pledgor has, independently and without reliance upon the
Administrative Agent and based on such documents and information as it has
deemed appropriate, made its own credit analysis and decision to enter into this
Agreement.

                                       5
<PAGE>   165

         SECTION 9. Further Assurances. (a) Pledgor agrees that from time to
time, at the expense of Pledgor, Pledgor will promptly execute and deliver all
further instruments and documents, and take all further action, that may be
necessary, or that the Administrative Agent may reasonably request, in order to
perfect and protect the pledge, assignment, hypothecation and security interest
granted or purported to be granted hereby or to enable the Administrative Agent
to exercise and enforce its rights and remedies hereunder with respect to any
Collateral. Without limiting the generality of the foregoing, Pledgor will (i)
execute and file such financing or continuation statements, or amendments
thereto, and such other instruments or notices, as may be necessary, or as the
Administrative Agent may reasonably request, in order to perfect and preserve
the assignment, hypothecation and security interest granted or purported to be
granted hereby; and (ii) mark conspicuously, at the request of the
Administrative Agent, each of its records pertaining to the Collateral with a
legend, in form and substance satisfactory to the Administrative Agent,
indicating that the Partnership Agreement and such chattel paper have been
assigned and are subject to the security interest pursuant hereto.

         (b)      Pledgor hereby further authorizes the Administrative Agent to
file one or more financing or continuation statements, and amendments thereto,
relative to all or any part of the Collateral without the signature of Pledgor
where permitted by law. A photocopy or other reproduction of this Agreement or
any financing statement covering the Collateral or any part thereof shall be
sufficient as a financing statement where permitted by law.

         SECTION 10. Voting Rights; Distributions, Etc. (a) So long as no Event
of Default shall have occurred and be continuing, but subject, nevertheless, at
all times to the restrictions imposed by Section 6.10 of the Credit Agreement
and by subsection (b) below, Pledgor shall be entitled to receive free and clear
of the interest of the Administrative Agent granted under this Agreement all
payments and other distributions receivable by it under the Partnership
Agreement that are Distributions expressly permitted by the Deposit Account
Agreement and the Credit Agreement, and shall be entitled to exercise any and
all management, voting and other partnership rights pertaining to any Collateral
including but not limited to any partnership interest or the Partnership
Agreement for any purpose not inconsistent with the terms of this Agreement or
any other Financing Document; provided, however, that Pledgor shall exercise, or
refrain from exercising, any such right if such action or inaction would have a
material adverse effect on the attachment, perfection, creation or priority of
the security interest in the Collateral or any part thereof as herein granted.

         (b)      Pledgor's right to receive and retain any and all
distributions in respect of the Collateral purported to be pledged and assigned
by it hereunder shall be further limited as follows:

                  (i) distributions other than in cash in respect of, and
                  instruments and other property received, receivable or
                  otherwise distributed in respect of, or in exchange for, any
                  such Collateral, and

                  (ii) distributions paid or payable in cash in respect of any
                  such Collateral in connection with a partial or total
                  liquidation or dissolution of the Borrower, shall be, and
                  shall be forthwith delivered to the Administrative Agent to
                  hold as, Collateral and shall, if received by Pledgor, be
                  received in trust for the benefit of

                                       6
<PAGE>   166

                  the Administrative Agent, be segregated from the other
                  property or funds of Pledgor and be forthwith delivered to the
                  Administrative Agent as Collateral in the same form as so
                  received (with any necessary endorsement or assignment).

         (c)      Upon the occurrence and during the continuance of an Event of
Default:

                  (i) Immediately upon Pledgor's receipt of written notice from
                  the Administrative Agent that the Administrative Agent intends
                  to act pursuant to this clause (c)(i), all rights of Pledgor
                  to exercise or refrain from exercising the voting and other
                  consensual rights which it would otherwise be entitled to
                  exercise shall thereupon become exercisable by the
                  Administrative Agent, acting in good faith, who shall have the
                  sole right to exercise or refrain from exercising such voting
                  and other consensual rights unless and until such Event of
                  Default ceases to exist.

                  (ii) All rights of Pledgor to receive the distributions which
                  it would otherwise be authorized to receive and retain,
                  pursuant to Section 9(a) and (b), above, shall become
                  exercisable by the Administrative Agent who shall thereupon
                  have the sole right to receive and hold as Collateral such
                  distributions unless and until such Event of Default ceases to
                  exist.

                  (iii) All distributions which are received by Pledgor contrary
                  to the provisions of clause (ii), above, shall be received in
                  trust for the benefit of the Administrative Agent, shall be
                  segregated from other funds of Pledgor and shall be forthwith
                  paid over to the Administrative Agent as Collateral in the
                  same form as so received (with any necessary endorsement) for
                  application pursuant to Section 17.

         SECTION 11. Place of Perfection; Records. Pledgor shall keep its place
of business and chief executive office and the office where it keeps its records
concerning the Collateral, and original copies of the Partnership Agreement and
of all other chattel paper which evidence the Collateral, at its address
specified on the signature pages hereof; or, upon 30 days' prior written notice
to the Administrative Agent, at such other location in a jurisdiction where all
action required by Section 8 shall have been taken with respect to the
Collateral. Pledgor will hold and preserve such records and will permit
representatives of the Administrative Agent at any time, upon reasonable prior
notice, during normal business hours to inspect and make abstracts from such
records.

         SECTION 12. As to the Partnership Agreement. (a) Pledgor shall at its
expense perform and observe all the terms and provisions to be performed or
observed by it under the Partnership Agreement, maintain the Partnership
Agreement in full force and effect, enforce the Partnership Agreement in
accordance with its terms, and take all such action to such end as may be from
time to time reasonably requested by the Administrative Agent.

         (b)      Pledgor shall not:

                  (i) sell, assign (by operation of law or otherwise) or
                  otherwise dispose of any of the Collateral, or create or
                  suffer to exist any Lien upon or with respect to any of the
                  Collateral, except for the pledge, assignment, hypothecation
                  and security interest created by this Agreement and Permitted
                  Liens;

                                       7
<PAGE>   167

                  (ii) cancel or terminate the Partnership Agreement or consent
                  to or accept any cancellation or termination thereof;

                  (iii) amend or otherwise modify in a material respect the
                  Partnership Agreement; or

                  (iv) waive any material default under or material breach of
                  the Partnership Agreement.

         SECTION 13. Covenants. Pledgor covenants and agrees that so long as any
Lender shall have any Commitment outstanding and until the Notes, together with
interest, and all other Secured Obligations are indefeasibly paid in full,
unless the Administrative Agent shall otherwise consent in writing, Pledgor:

         (a)      Maintenance of Register. Will cause the Borrower to maintain
at all times a register at its chief place of business and chief executive
office in which the security interest in the Collateral granted hereby to the
Administrative Agent, to the extent that the same constitutes "uncertificated
securities" (as defined in the Delaware UCC), shall be evidenced.

         (b)      Preservation of Existence, Etc. Will preserve and maintain,
and will cause the Borrower to preserve and maintain, its lawful existence,
rights (charter and statutory), and franchises.

         (c)      Compliance with Law. Will comply with all material
Requirements of Law and material Governmental Approvals applicable to it, except
when any such Requirement of Law or Governmental Approval is being contested in
good faith and by appropriate proceedings and for which Acceptable Reserves have
been established.

         (d)      Change in Nature of Business. Will not engage in any business
other than as set forth in the Pledgor's Certificate of Incorporation, as in
effect on the date hereof.

of the Borrower as debtor under any applicable federal or state law relating to
bankruptcy, insolvency, or other relief for debtors with respect to the
Borrower; or seek or consent to the appointment of any trustee, receiver,
conservator, assignee, sequestrator, custodian, liquidator (or other similar

and assets of the Borrower, or make any general assignment for the benefit of
creditors of the Borrower, or admit in writing the inability of the Borrower to
pay its debts generally as they become due or declare or effect a moratorium on
the debt of the Borrower or take any action in furtherance of any action;

         (g)      Taxes. Will pay and discharge or cause to be paid or
discharged all taxes, assessments and governmental charges or levies lawfully

the Collateral and all lawful claims or obligations that, if unpaid, would
become a Lien upon the Collateral (as defined in the Credit Agreement), whether
real or personal, the Collateral (as defined in this Agreement) or upon any part
thereof. The Pledgor shall have the right, however, to contest in good faith the
validity or amount of any such tax, assessment, charge or levy by proper
proceedings, and may permit the taxes, assessments, charges or levies so
contested to remain unpaid during the period of such contest if: (a) the Pledgor
diligently prosecutes such contest in good faith and by appropriate proceedings
and has established Acceptable Reserves; (b) during the period of such contest,
the enforcement of any contested item is effectively stayed; and (c) the failure
to pay or comply with the contested item could not reasonably be expected to

                  (x) to correct any misunderstanding regarding its separate
                  identity of which the Pledgor has actual knowledge;

                  (xi) not to identify itself in writing as a division of any
                  other Person; and

Administrative Agent may deem to be necessary or desirable for the collection
thereof or to enforce compliance with the terms and conditions of the
Partnership Agreement. Such appointment is coupled with an interest and is
irrevocable.

         SECTION 15. Administrative Agent May Perform. If Pledgor fails to

Agent, shall be segregated from other funds of Pledgor and shall be forthwith
paid over to the Administrative Agent in the same form as so received (with any
necessary endorsement).

         (c)      Any Collateral repossessed by the Administrative Agent under
or pursuant to this Section 16 or any other provision hereof, and any other
Collateral whether or not so repossessed by the Administrative Agent, may be
sold, assigned, leased or otherwise disposed of under one or more contracts or
as an entirety, and without the necessity of gathering at the place of sale the
property to be sold, and in general in such manner, at such time or times, at
such place or places and on such terms as the Administrative Agent may, upon
written direction in compliance with any mandatory requirements of any
Requirement of Law, determine to be commercially reasonable. Any such
disposition which shall be a private sale or other private proceeding permitted
by such requirements shall be made upon not less than 10 days' written notice to
Pledgor specifying the time at which such disposition is to be made and the
intended sale price or other consideration therefor, and shall be subject, for
the 10 days after the giving of such notice, to the right of the Pledgor or any
nominee of Pledgor to acquire the Collateral involved at a price or for such
other consideration at least equal to the intended sale price or other
consideration so specified. To the extent permitted by Requirements of Law, the
Administrative Agent on behalf of the Lenders may bid for and become the
purchaser of the Collateral or any item thereof, offered for sale in accordance
with this Section 16. If, under mandatory requirements of any Requirement of
Law, the Administrative Agent shall be required to make disposition of the
Collateral within a period of time which does not permit the giving of notice to
Pledgor as hereinabove specified, the Administrative Agent need give Pledgor
only such notice of disposition as shall be reasonably practicable in view of
such mandatory requirements of any Requirement of Law.

         (d)      All payments made under or in connection with, or proceeds
realized from, the Partnership Agreement, the Partnership Interests, or
otherwise in respect of the Collateral and received by the Administrative Agent,
shall be applied in whole or in part by the Administrative Agent against, all or
any part of the Secured Obligations in accordance with the terms of the Deposit
Account Agreement. Any surplus of such payments held by the Administrative Agent
and remaining after payment in full of all the Secured Obligations shall be paid
over to Pledgor or to whomsoever else may be lawfully entitled to receive such
surplus.

         (e)      Waiver of Claims. Except as otherwise provided in this
Agreement, PLEDGOR HEREBY WAIVES, TO THE EXTENT PERMITTED BY APPLICABLE
REQUIREMENTS OF LAW, NOTICE AND JUDICIAL HEARING IN CONNECTION WITH THE
ADMINISTRATIVE AGENT TAKING POSSESSION OR THE ADMINISTRATIVE AGENT'S DISPOSITION
OF ANY OF THE COLLATERAL, IN EACH CASE AS PERMITTED BY APPLICABLE REQUIREMENTS
OF LAW, INCLUDING, WITHOUT LIMITATION, ANY AND ALL PRIOR NOTICE AND HEARING FOR
ANY PREJUDGMENT REMEDY OR REMEDIES AND ANY SUCH RIGHT WHICH PLEDGOR WOULD
OTHERWISE HAVE UNDER THE CONSTITUTION OR ANY STATUTE OF THE UNITED STATES OR ANY
POLITICAL SUBDIVISION OF ANY SUCH JURISDICTION, and Pledgor hereby further
waives:

                                       11
<PAGE>   171

                  (i) all damages occasioned by such taking of possession except
                  any damages which are the direct result of the gross
                  negligence or willful misconduct of either of the
                  Administrative Agent or any Person acting on its behalf or
                  instruction;

                  (ii) all other requirements as to the time, place and terms of
                  sale or other requirements with respect to the enforcement of
                  the Administrative Agent's rights hereunder; and

                  (iii) all rights of redemption, appraisement, valuation, stay,
                  extension or moratorium now or hereafter in force under any
                  Requirements of Law in order to prevent or delay the
                  enforcement of this Agreement (including, without limitation,
                  any right to claim that such enforcement should be stayed
                  pending the outcome of any other action or proceeding
                  (including any arbitration proceeding)) or the absolute sale
                  of the Collateral or any portion thereof, and Pledgor, for
                  itself and all who may claim under it, insofar as it or they
                  now or hereafter lawfully may, hereby waives the benefit of
                  all such Requirements of Law.

Any sale of, or the grant of options to purchase, or any other realization upon,
any Collateral shall, to the extent permitted by Requirements of Law, operate to
divest all right, title, interest, claim and demand, either at law or in equity,
of Pledgor therein and thereto, and shall be a perpetual bar both at law and in
equity against Pledgor and against any and all Persons claiming or attempting to
claim the Collateral so sold, optioned or realized upon, or any part thereof,
from, through and under Pledgor.

         SECTION 18. Application of Proceeds. Notwithstanding any other
provision of this Agreement, all moneys collected by the Administrative Agent
upon any sale or other disposition of the Collateral pursuant to Section 16,
together with all other moneys received by the Administrative Agent hereunder,
shall be applied in accordance with the Deposit Account Agreement.

         SECTION 19. Remedies Cumulative. No failure or delay on the part of the
Administrative Agent or any Secured Party in exercising any right, power or
privilege hereunder or under any other Financing Document and no course of
dealing between Pledgor and the Administrative Agent or any Secured Party shall
operate as a waiver thereof; nor shall any single or partial exercise of any
right, power or privilege hereunder or under any other Financing Document
preclude any other or further exercise thereof or the exercise of any other
right, power or privilege hereunder or thereunder. The rights, powers and
remedies herein or in any other Financing Document expressly provided are
cumulative and not exclusive of any rights, powers or remedies which the
Administrative Agent or any Secured Party would otherwise have. No notice to or
demand on Pledgor in any case shall entitle Pledgor to any other or further
notice or demand in similar or other circumstances or constitute a waiver of the
rights of the Administrative Agent or any Secured Party to any other or further
action in any circumstances without notice or demand.

         SECTION 20. Discontinuance of Proceedings. In case the Administrative
Agent shall have instituted any proceeding to enforce any right, power or remedy
under this Agreement by foreclosure, sale or otherwise, and such proceeding
shall have been discontinued or abandoned

                                       12
<PAGE>   172

for any reason or shall have been determined adversely to the Administrative
Agent, then and in every such case Pledgor, the Administrative Agent and each
holder of any of the Secured Obligations shall be restored to their former
positions and rights hereunder with respect to the Collateral subject to the
security interest created under this Agreement, and all rights, remedies and
powers of the Administrative Agent shall continue as if no such proceeding had
been instituted.

         SECTION 21. Indemnity and Expenses. (a) Pledgor agrees to indemnify and
hold harmless the Administrative Agent and each Secured Party from and against
any and all claims, losses and liabilities arising out of or resulting from the
Collateral or Pledgor's pledge and assignment under this Agreement (including,
without limitation, enforcement against Pledgor of this Agreement), except
claims, losses or liabilities resulting from the Administrative Agent's or any
Secured Party's gross negligence or willful misconduct.

         (b)      Pledgor will upon demand pay to the Administrative Agent or
any Secured Party the amount of any and all reasonable expenses, including the
reasonable fees and expenses of its counsel and of any experts and agents, which
the Administrative Agent or any Secured Party may incur in connection with (i)
the administration of this Agreement, (ii) the sale of, collection from, or
other realization upon, any of the Collateral of Pledgor, (iii) the exercise or
enforcement (whether through negotiations, legal proceedings or otherwise) of
any of the rights of the Administrative Agent or any Secured Party hereunder
against Pledgor or (iv) the failure by Pledgor to perform or observe any of the
provisions hereof.

         SECTION 22. Security Interest Absolute. The obligations of Pledgor
under this Agreement are independent of the Secured Obligations, and a separate
action or actions may be brought and prosecuted against Pledgor to enforce this
Agreement, irrespective of whether any action is brought against the Borrower,
any other pledgor or any guarantor of the Secured Obligations or whether the
Borrower, any other pledgor or any guarantor of the Secured Obligations is
joined in any such action or actions. All rights of the Administrative Agent and
the assignment, hypothecation and security interest hereunder, and all
obligations of Pledgor hereunder, shall be absolute and unconditional, to the
extent permitted by applicable law, irrespective of:

         (a)      any lack of validity or enforceability of this Agreement, the
Credit Agreement, any other Financing Document or any other agreement or
instrument relating to any thereof, the absence of any action to enforce the
same, any release of the Borrower or Pledgor, the recovery of any judgment
against the Borrower or Pledgor, any action to enforce the same or any other
circumstance which might otherwise constitute a legal or equitable discharge or
defense of Pledgor;

         (b)      any occurrence or condition whatsoever, including without
limitation, (i) any compromise, settlement, release, waiver, renewal, extension,
indulgence or modification of, or any change in, any of the obligations of the
Borrower or Pledgor contained in this Agreement, the Credit Agreement or any
other Financing Document, (ii) any impairment, modification, release or
limitation of the liability of the Borrower or Pledgor or any of their estates
in bankruptcy, or any remedy for the enforcement thereof, resulting from the
operation of any present or future provision of any applicable bankruptcy law,
as amended, or other statute or

                                       13
<PAGE>   173

from the decision of any court, (iii) the assertion or exercise by Pledgor, the
Administrative Agent or any other Secured Party of any rights or remedies, (iv)
the assignment or the purported assignment of any property as security for the
Secured Obligations, including all or any part of the rights of Pledgor under
this Agreement, (v) the extension of the time for payment by the Borrower or any
other guarantor of any payments or other sums or any part thereof owing or
payable under any of the terms and provisions of any Financing Document or of
the time for performance by the Borrower or Pledgor of any other obligations
under or arising out of any terms or provisions or the extension of the renewal
of any thereof, (vi) the modification or amendment (whether material or
otherwise) of any duty, agreement or obligation of the Borrower or Pledgor set
forth in any Financing Document, (vii) the voluntary or involuntary liquidation,
dissolution, sale or other disposition of all or substantially all of the
assets, marshalling of assets and liabilities, receivership, insolvency,
bankruptcy, assignment for the benefit of creditors, reorganization,
arrangement, composition or readjustment of, or other similar proceeding
affecting the Borrower or Pledgor or any of their respective assets, or the
disaffirmancy of this Agreement or any Financing Document in any such
proceeding, (viii) the release or discharge of the Borrower or Pledgor from the
performance or observance of any agreement, covenant, term or condition
contained in any of such instruments by operation of law, (ix) the
unenforceability of this Agreement or any Financing Document or (x) any other
circumstance which might otherwise constitute a legal or equitable discharge of
a surety or guarantor; or

         (c)      any exchange, release or non-perfection of any collateral, or
any release or amendment or waiver of or consent to departure from any other
guarantee, for all or any of the Secured Obligations.

         SECTION 23. Amendment; Waiver. No amendment or waiver of any provision
of this Agreement shall be effective unless the same shall be undertaken and
accomplished in accordance with the requirements of Section 9.02 of the Credit
Agreement. No delay on the part of any Secured Party in the exercise of any
right, power or remedy shall operate as a waiver thereof, nor shall any single
or partial waiver by such Secured Party of any right, power or remedy preclude
any further exercise thereof, or the exercise of any other right, power or
remedy.

         SECTION 24. Addresses for Notices. All notices, requests and other
communications to Pledgor or the Administrative Agent shall be in writing
(including bank wire, cable, telex, telecopy or similar teletransmission or
writing) and shall be given, in the case of Pledgor to its address, or telex,
cable or telecopy number set forth on the signature page hereof, and in the case
of the Administrative Agent, to it at its address, or telex, cable or telecopy
number set forth in Annex II to the Credit Agreement or such other address or
telex, cable or telecopy number as each party may hereafter specify by notice to
such other party. Each such notice, request or other communication shall be
effective (i) if given by telex, when such telex is transmitted to the telex
number specified on the signature page hereof or in Annex II, as the case may
be, and the appropriate answerback is received, (ii) if given by telecopy, when
such telecopy is transmitted to the telecopy number specified on the signature
page hereof or in Annex II, as the case may be, and receipt thereof is confirmed
in writing, or (iii) if given by any other means (including, without limitation,
by air courier), when delivered at the address specified on the signature page
hereof or in Annex II, as the case may be.

<PAGE>   174

         SECTION 25. Continuing Assignment, Pledge and Security Interest,
Transfer of Note. This Agreement shall create a continuing pledge, assignment
of, hypothecation of and security interest in the Collateral and shall (i)
remain in full force and effect until no Lender shall have any Commitment
outstanding, and until the Notes, together with interest, and all other Secured
Obligations are indefeasibly paid in full, (ii) be binding upon Pledgor, its
successors and assigns, provided, that Pledgor may not transfer or assign any or
all of its rights or obligations hereunder without the prior written consent of
each Lender, and (iii) inure to the benefit of, and be enforceable by, the
Administrative Agent, the Secured Parties and their respective successors,
transferees and assigns. Without limiting the generality of the foregoing clause
(iii), any Secured Party may assign or otherwise transfer all or any portion of
its rights in the Secured Obligations to the extent and in the manner provided
in the Credit Agreement, and such assignee shall thereupon become vested with
all the benefits in respect thereof granted to such Secured Party herein or
otherwise. Upon the indefeasible payment in full of the Secured Obligations and
the expiration or termination of the Commitments, the security interest granted
hereby shall terminate and all rights to the Collateral shall revert to Pledgor.
Upon any such termination, the Administrative Agent will, at Pledgor's expense,
execute and deliver to Pledgor such documents including UCC termination
statements as Pledgor shall reasonably request to evidence such termination.

         SECTION 26. Severability. Any provision hereof that is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof and without affecting the validity or enforceability
of any provision in any other jurisdiction.

         SECTION 27. GOVERNING LAW; TERMS. THIS AGREEMENT SHALL BE GOVERNED BY
AND INTERPRETED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK OTHER THAN
ANY SUCH REQUIREMENT OF LAWS THAT WOULD APPLY THE LAWS OF ANOTHER JURISDICTION,
EXCEPT TO THE EXTENT THAT THE LAWS OF ANOTHER JURISDICTION ARE MANDATORILY
APPLICABLE AND EXCEPT TO THE EXTENT THAT THE VALIDITY OR PERFECTION OF THE
SECURITY INTEREST HEREUNDER, OR REMEDIES HEREUNDER, IN RESPECT OF ANY PARTICULAR
COLLATERAL ARE GOVERNED BY THE LAWS OF A JURISDICTION OTHER THAN THE STATE OF
NEW YORK. UNLESS OTHERWISE DEFINED HEREIN OR IN THE CREDIT AGREEMENT, TERMS USED
IN ARTICLE 9 OF THE NY UCC ARE USED HEREIN AS THEREIN DEFINED. ANY DISPUTE
ARISING OUT OF, CONNECTED WITH, RELATED TO, OR INCIDENTAL TO THE RELATIONSHIP
ESTABLISHED BETWEEN THE PLEDGOR AND EACH SECURED PARTY IN CONNECTION WITH THIS
AGREEMENT AND THE OTHER FINANCING DOCUMENTS, AND WHETHER ARISING IN CONTRACT,
TORT, EQUITY OR OTHERWISE, SHALL BE RESOLVED IN ACCORDANCE WITH THE INTERNAL
LAWS (AS OPPOSED TO THE CONFLICTS OF LAWS PROVISIONS) AND DECISIONS OF THE STATE
OF NEW YORK.

         SECTION 28. CONSENT TO JURISDICTION; WAIVER OF JURY TRIAL. (a) PLEDGOR
AND EACH SECURED PARTY AGREE THAT ALL DISPUTES BETWEEN THEM ARISING OUT OF,
CONNECTED WITH, RELATED TO, OR INCIDENTAL TO THE RELATIONSHIP ESTABLISHED
BETWEEN THEM IN CONNECTION WITH THIS AGREEMENT AND THE OTHER FINANCING
DOCUMENTS, AND WHETHER ARISING

                                       15
<PAGE>   175

IN CONTRACT, TORT, EQUITY, OR OTHERWISE, SHALL BE RESOLVED ONLY BY STATE OR
FEDERAL COURTS LOCATED IN NEW YORK, NEW YORK, BUT PLEDGOR AND EACH SECURED PARTY
ACKNOWLEDGE THAT ANY APPEALS FROM THOSE COURTS MAY HAVE TO BE HEARD BY A COURT
LOCATED OUTSIDE OF NEW YORK, NEW YORK. PLEDGOR WAIVES IN ALL DISPUTES ANY
OBJECTION THAT IT MAY HAVE TO THE LOCATION OF THE COURT CONSIDERING THE DISPUTE
INCLUDING, WITHOUT LIMITATION, ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON
THE GROUNDS OF FORUM NON CONVENIENS.

         (b)      PLEDGOR AND THE SECURED PARTIES EACH WAIVE ANY RIGHT TO HAVE A
JURY PARTICIPATE IN RESOLVING ANY DISPUTE, WHETHER SOUNDING IN CONTRACT, TORT,
OR OTHERWISE ARISING OUT OF, CONNECTED WITH, RELATED TO OR INCIDENTAL TO THE
RELATIONSHIP ESTABLISHED BETWEEN THEM IN CONNECTION WITH THIS AGREEMENT AND THE
OTHER FINANCING DOCUMENTS. INSTEAD, ANY DISPUTES RESOLVED IN COURT WILL BE
RESOLVED IN A BENCH TRIAL WITHOUT A JURY.

         SECTION 29. Execution in Counterparts. This Agreement may be executed
in any number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed shall be deemed to be an original
and all of which taken together shall constitute one and the same instrument.

         SECTION 30. Limitation on Recourse. The obligations of Pledgor
hereunder are obligations solely of Pledgor and shall not constitute a debt or
obligation of any direct or indirect partner or shareholder of Pledgor or any of
their respective directors, officers, agents or employees (each such Person, a
"Non-Recourse Party"). No Non-Recourse Party shall be liable for any amount
payable by Pledgor under this Agreement and the Secured Parties shall not seek a
money judgment or deficiency or personal judgment against any Non-Recourse Party
for payment of the indebtedness payable by Pledgor evidenced by this Agreement.
No property or assets of any Non-Recourse Party, other than as provided in the
Financing Documents, shall be sold, levied upon or otherwise used to satisfy any
judgment rendered in connection with any action brought against Pledgor with
respect to this Agreement or the other Financing Documents. The foregoing
acknowledgments, agreements and waivers shall be enforceable by any Non-Recourse
Party. Notwithstanding the foregoing, nothing in this Section shall limit or
affect or be construed to limit or affect the obligations and liabilities of any
Credit Party or any other Non-Recourse Party (a) in accordance with the terms of
any Transaction Document or Financing Document creating such liabilities and
obligations to which such Credit Party or Non-Recourse Party is a party, (b)
arising from liability pursuant to applicable Requirements of Law for such
Credit Party's or such Non-Recourse Party's fraudulent actions, knowing
misrepresentations or willful misconduct or (c) with respect to amounts
distributed to it in violation of Section 6.10 of the Credit Agreement.

the implementation of this Agreement;

         NOW, THEREFORE, in consideration of the foregoing and in order to
induce the Lenders to enter into the Credit Agreement, to make available to the
Borrower such credit facilities and for other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, Pledgor hereby
agrees as follows:

         Section 1. Pledge; Assignment; Grant of Security Interest. Pledgor
hereby pledges, hypothecates and assigns to the Administrative Agent, and
hereby grants to the Administrative Agent for the benefit of the Secured
Parties, a pledge and assignment of, and a security interest in, all of its
right, title and interest in and to the following (the "Collateral"):

         (a)      All general and limited partnership interests now owned or
hereafter acquired by Pledgor in and to the Borrower (collectively, the
"Partnership Interests") and the partnership agreement relating to the Borrower
(the "Partnership Agreement") and all rights related thereto, including,
without limitation, (i) all rights of Pledgor as a general or limited partner,
as the case may be, and all rights to receive distributions, cash, instruments
and other property from time to time receivable or otherwise distributable in
respect of any Partnership Interests or pursuant to the Partnership Agreement,
(ii) all rights of Pledgor to receive proceeds of any insurance, indemnity,
warranty or guaranty with respect to any Partnership Interests or the
Partnership Agreement, (iii) all claims of Pledgor for damages arising out of
or for breach of or default under the Partnership Agreement, (iv) the right of
Pledgor to terminate the Partnership Agreement, to perform and exercise
consensual or voting rights thereunder and to compel performance and otherwise
exercise all remedies thereunder, (v) all rights of Pledgor as a general or
limited partner of the Borrower, to any property and assets of the Borrower
(whether real property, inventory, equipment, contract rights, accounts,
receivables, general intangibles, securities, instruments, chattel paper,
documents, chooses in action or otherwise), and (vi) all certificates or
instruments evidencing an ownership or partnership interest in the Borrower or
its assets; and

         (b)      to the extent not included in the foregoing, all proceeds of
any and all of the foregoing (including, without limitation, proceeds that
constitute property of the types described above).

         Section 2.     Security for Secured Obligations. This Agreement
secures the prompt and complete payment and performance of (a) all Obligations
of the Borrower now or hereafter existing under the Financing Documents, and
(b) the due performance and compliance of all other obligations of the Borrower
under any of the Financing Documents (collectively, the "Secured Obligations").
Without limiting the generality of the foregoing, this Agreement secures the
payment of all amounts which constitute part of the Secured Obligations and
would be owed by the Borrower to the Secured Parties but for the fact that they
are unenforceable or not allowable due to the existence of a bankruptcy,
reorganization or similar proceeding involving any Credit Party.

         Section 3.     Pledgor Remains Liable. Anything herein to the contrary
notwithstanding, (a) Pledgor shall remain liable under the Partnership
Agreement and the other contracts and agreements included in the Collateral to
the extent set forth therein to

                                       2

<PAGE>   181

perform all of its duties and obligations thereunder to the same extent as if
this Agreement had not been executed, (b) the exercise by any Secured Party of
any of the rights hereunder shall not release Pledgor from any of its duties or
obligations under the contracts and agreements included in the Collateral and
(c) neither the Administrative Agent nor any Secured Party shall have any
obligation or liability under the contracts and agreements included in the
Collateral or otherwise by reason of this Agreement, nor shall the
Administrative Agent or any Secured Party be obligated to perform any of the
obligations or duties of Pledgor thereunder or to take any action to collect or
enforce any claim assigned hereunder.

         Section 4.     Delivery of Collateral. All certificates or instruments
representing or evidencing the Collateral at any time shall be delivered to and
held by or on behalf of the Administrative Agent pursuant hereto and shall be
in suitable form for transfer by delivery, or shall be accompanied by duly
executed instruments of transfer or assignment in blank, all in form and
substance satisfactory to the Administrative Agent. The Administrative Agent
shall have the right, upon the occurrence and continuance of an Event of
Default, in its discretion and without notice to Pledgor, to transfer to or to
register in the name of the Administrative Agent or any of its nominees any or
all of the Collateral, subject only to compliance with Requirements of Law, the
terms and conditions of the Credit Agreement and the revocable rights specified
in Section 9(a). In addition, the Administrative Agent shall have the right at
any time to exchange certificates or instruments representing or evidencing
Collateral for certificates or instruments of smaller or larger denominations.

         Section 5.     No Subrogation. Pledgor shall not exercise any rights
which it may acquire by way of subrogation under this Agreement, by any
payments made hereunder or otherwise, until all Secured Obligations shall have
been indefeasibly paid in full and all Commitments have been terminated. If any
amount shall be paid to Pledgor on account of such subrogation rights at any
time when all Secured Obligations shall not have been indefeasibly paid in full
(whether pursuant to a claim in any bankruptcy or similar proceeding or
otherwise) or when any Commitment shall remain outstanding, such amount shall
be held in trust for the benefit of the Administrative Agent and the Secured
Parties and shall forthwith be paid to the Administrative Agent to be credited
and applied to the Secured Obligations, whether matured or unmatured, in
accordance with Section 17.

         Section 6.     Reinstatement. This Agreement shall continue to be
effective, or be reinstated, as the case may be, if at any time payment, or any
part thereof, of any of the Secured Obligations is rescinded or must otherwise
be restored or returned by any Secured Party upon the insolvency, bankruptcy,
dissolution, liquidation or reorganization of Pledgor, or upon or as a result
of the appointment of a receiver, intervenor or conservator of, or trustee or
similar officer for, Pledgor or any substantial part of its property, or
otherwise, all as though such payments had not been made.

         Section 7.        Representations and Warranties.  Pledgor represents
and warrants as follows:

standing under the laws of the State of Delaware, (ii) has all requisite power
and authority to own its property and assets, to borrow money and to transact
the business in which it is presently engaged and in which it proposes to be
engaged, (iii) has duly qualified and is authorized to do business and is in
good standing in every jurisdiction where the character of its properties or
the nature of its activities makes such qualification necessary and (iv) is in

         (b)      The execution, delivery and performance by Pledgor of this
Agreement and the consummation of the transactions contemplated hereby (i) are
within its powers, (ii) have been duly authorized by all necessary corporate
action, (iii) do not and will not contravene (A) its Governing Documents or (B)
any material Requirement of Law, any material Contractual Obligation or any
material Governmental Approval binding on or affecting it and (iv) does not and
will not conflict with or be inconsistent with or result in any breach of any
of the material terms, covenants, conditions or provisions of, or constitute a
default under, or result in the creation or imposition of (or the obligation to
create or impose) any Lien (except Permitted Liens) upon any of its properties
or assets pursuant to, the terms of any material Contractual Obligation binding
on or affecting it.

         (c)      Pledgor has duly executed and delivered this Agreement and
this Agreement constitutes the legal, valid and binding obligation of Pledgor,
enforceable against Pledgor in accordance with its terms, except as enforcement
thereof may be subject to (i) the effect of any applicable bankruptcy,
insolvency, reorganization, moratorium or similar laws affecting creditors'
rights generally and (ii) general principles of equity.

         (d)      No Governmental Approval or approval of any other Person

consummation of any of the transactions contemplated hereby, (ii) the legality,
validity, binding effect or enforceability of this Agreement or the perfection

priority nature of such security interest) or (iii) for the exercise by the

Agreement or the remedies in respect of the Collateral pursuant to this
Agreement. All applicable waiting periods relating to any such Governmental
Approval or other approval which are required and have been obtained have
expired without any adverse action taken with respect thereto.

         (e)      The Partnership Agreement, a true and complete copy of which
has been furnished to the Administrative Agent, has been duly authorized,
executed and delivered by Pledgor and is in full force and effect and is
binding upon and enforceable against Pledgor in accordance with its terms.
There exists no default under the Partnership Agreement.

                                       4

<PAGE>   183

         (f)      This Agreement creates a valid security interest in the
Collateral purported to be pledged and assigned by Pledgor hereunder securing
the payment of the Secured Obligations.

         (g)      Upon the filing of the financing statements (the "Financing
Statements") referenced in Schedule I hereof under the Uniform Commercial Code
as in effect in the State of Delaware (the "Delaware UCC"), the security
interest is created hereby shall be perfected under the Delaware UCC, to the
extent that the Collateral constitutes "general intangibles" (as defined in the
Delaware UCC) and no further filings or other actions are necessary to perfect
such security interest. Upon filing of such Financing Statements pursuant to
the Delaware UCC, such security interests, as so perfected, are first priority
security interests.

         (h)      When any certificates or instruments evidencing the
Collateral shall be delivered hereunder, and for so long as such certificates
or instruments shall remain in the possession of the Administrative Agent in
the State of New York or the State of North Carolina, the security interest in
such Collateral created hereby shall be perfected under the Uniform Commercial
Code as in effect in the State of New York (the "NY UCC") or the State of North
Carolina, as applicable, and such security interest, as so perfected, will be a
first priority security interest.

         (i)      The security interest created by this Agreement in the
Collateral described in clause (a) of Section 1 hereof has been registered in
the name of the Administrative Agent in the register maintained for such
purpose at the chief executive office and principal place of business of the
Borrower, and, to the extent that such Collateral constitutes "uncertificated
securities" (as defined in the Delaware UCC), such security interest is
perfected under the Delaware UCC and, as so perfected, is a first priority
security interest.

         (j)      The chief place of business and chief executive office of
Pledgor and the office where Pledgor keeps its records concerning the
Collateral is set forth under its name on the signature page hereof.

         (k)      Pledgor is the legal and beneficial owner of the Collateral
purported to be pledged and assigned by it hereunder, free and clear of any
Lien, other than Permitted Liens. No effective financing statement or other
instrument similar in effect covering all or any part of such Collateral has
been executed or authorized by Pledgor or, is on file in any recording office,
except such as may have been filed in favor of the Administrative Agent
relating to this Agreement. Pledgor has no trade name.

         (l)      There are no conditions precedent to the effectiveness of
this Agreement that have not been satisfied or waived.

         (m)      No part of the Collateral is subject to the terms of any
agreement restricting the sale or transfer of such Collateral, except for the
Partnership Agreement and the Financing Documents.

                                       5

<PAGE>   184

         (n)      There is no (i) injunction, writ, preliminary restraining
order or order of any nature issued by an arbitrator, court or other
Governmental Authority against Pledgor in connection with the transactions
provided for herein, or (ii) action, suit, arbitration, litigation,
investigation or proceeding of or before any arbitrator or Governmental
Authority pending against Pledgor or, to Pledgor's knowledge, threatened
against Pledgor which would reasonably be expected to materially adversely
affect the right or ability of Pledgor to fulfill its obligations under this
Agreement.

         (o)      Pledgor has, independently and without reliance upon the
Administrative Agent and based on such documents and information as it has
deemed appropriate, made its own credit analysis and decision to enter into
this Agreement.

         Section 8.     Further Assurances. (a) Pledgor agrees that from time
to time, at the expense of Pledgor, Pledgor will promptly execute and deliver
all further instruments and documents, and take all further action, that may be
necessary, or that the Administrative Agent may reasonably request, in order to
perfect and protect the pledge, assignment, hypothecation and security interest
granted or purported to be granted hereby or to enable the Administrative Agent
to exercise and enforce its rights and remedies hereunder with respect to any
Collateral. Without limiting the generality of the foregoing, Pledgor will (i)
execute and file such financing or continuation statements, or amendments
thereto, and such other instruments or notices, as may be necessary, or as the
Administrative Agent may reasonably request, in order to perfect and preserve
the assignment, hypothecation and security interest granted or purported to be
granted hereby; and (ii) mark conspicuously, at the request of the
Administrative Agent, each of its records pertaining to the Collateral with a
legend, in form and substance satisfactory to the Administrative Agent,
indicating that the Partnership Agreement and such chattel paper have been
assigned and are subject to the security interest pursuant hereto.

         (a)      Pledgor hereby further authorizes the Administrative Agent to
file one or more financing or continuation statements, and amendments thereto,
relative to all or any part of the Collateral without the signature of Pledgor
where permitted by law. A photocopy or other reproduction of this Agreement or
any financing statement covering the Collateral or any part thereof shall be
sufficient as a financing statement where permitted by law.

         Section 9.     Voting Rights; Distributions, Etc. (a) So long as no
Event of Default shall have occurred and be continuing, but subject,
nevertheless, at all times to the restrictions imposed by Section 6.10 of the
Credit Agreement and by subsection (b) below, Pledgor shall be entitled to
receive free and clear of the interest of the Administrative Agent granted
under this Agreement all payments and other distributions receivable by it
under the Partnership Agreement that are Distributions expressly permitted by
the Deposit Account Agreement and the Credit Agreement, and shall be entitled
to exercise any and all management, voting and other partnership rights
pertaining to any Collateral including but not limited to any partnership
interest or the Partnership Agreement in the Borrower for any purpose not
inconsistent with the terms of this Agreement or any other Financing Document;
provided, however, that Pledgor shall exercise, or refrain from exercising, any
such right if such action or inaction would have a

                                       6

<PAGE>   185

material adverse effect on the attachment, perfection, creation or priority of
the security interest in the Collateral or any part thereof as herein granted.

         (a)      Pledgor's right to receive and retain any and all
distributions in respect of the Collateral purported to be pledged and assigned
by it hereunder shall be further limited as follows:

                  (i)   distributions other than in cash in respect of, and
                  instruments and other property received, receivable or
                  otherwise distributed in respect of, or in exchange for, any
                  such Collateral, and

                  (ii)  distributions paid or payable in cash in respect of any
                  such Collateral in connection with a partial or total
                  liquidation or dissolution of the Borrower,

shall be, and shall be forthwith delivered to the Administrative Agent to hold
as, Collateral and shall, if received by Pledgor, be received in trust for the
benefit of the Administrative Agent, be segregated from the other property or
funds of Pledgor and be forthwith delivered to the Administrative Agent as
Collateral in the same form as so received (with any necessary endorsement or
assignment).

         (c)      Upon the occurrence and during the continuance of an Event of
Default:

                  (i)   Immediately upon Pledgor's receipt of written notice
                  from the Administrative Agent that the Administrative Agent
                  intends to act pursuant to this clause (c)(i), all rights of
                  Pledgor to exercise or refrain from exercising the voting and
                  other consensual rights which it would otherwise be entitled
                  to exercise shall thereupon become exercisable by the
                  Administrative Agent, acting in good faith, who shall have
                  the sole right to exercise or refrain from exercising such
                  voting and other consensual rights unless and until such
                  Event of Default ceases to exist.

                  (ii)  All rights of Pledgor to receive the distributions
                  which it would otherwise be authorized to receive and retain,
                  pursuant to Section 9(a) and (b), above, shall become
                  exercisable by the Administrative Agent who shall thereupon
                  have the sole right to receive and hold as Collateral such
                  distributions unless and until such Event of Default ceases
                  to exist.

                  (iii) All distributions which are received by Pledgor
                  contrary to the provisions of clause (ii), above, shall be
                  received in trust for the benefit of the Administrative
                  Agent, shall be segregated from other funds of Pledgor and
                  shall be forthwith paid over to the Administrative Agent as
                  Collateral in the same form as so received (with any
                  necessary endorsement) for application pursuant to Section
                  17.

         Section 10.    Place of Perfection; Records. Pledgor shall keep its
place of business and chief executive office and the office where it keeps its
records concerning

                                       7

<PAGE>   186

the Collateral, and original copies of the Partnership Agreement and of all
other chattel paper which evidence the Collateral, at its address specified on
the signature pages hereof; or, upon 30 days' prior written notice to the
Administrative Agent, at such other location in a jurisdiction where all action
required by Section 8 shall have been taken with respect to the Collateral.
Pledgor will hold and preserve such records and will permit representatives of
the Administrative Agent at any time, upon reasonable prior notice, during
normal business hours to inspect and make abstracts from such records.

         Section 11.    As to the Partnership Agreement. (a) Pledgor shall at
its expense perform and observe all the terms and provisions to be performed or
observed by it under the Partnership Agreement, maintain the Partnership
Agreement in full force and effect, enforce the Partnership Agreement in
accordance with its terms, and take all such action to such end as may be from
time to time reasonably requested by the Administrative Agent.

         (a)      Pledgor shall not:

                  (i)   sell, assign (by operation of law or otherwise) or
                  otherwise dispose of any of the Collateral, or create or
                  suffer to exist any Lien upon or with respect to any of the
                  Collateral, except for the pledge, assignment, hypothecation
                  and security interest created by this Agreement and Permitted
                  Liens;

                  (ii)  cancel or terminate the Partnership Agreement or
                  consent to or accept any cancellation or termination thereof;

                  Partnership Agreement; or

                  (iv)  waive any material default under or material breach of
                  the Partnership Agreement.

         Section 12. Covenants. Pledgor covenants and agrees that so long as
any Lender shall have any Commitment outstanding and until the Notes, together
with interest, and all other Secured Obligations are indefeasibly paid in full,
unless the Administrative Agent shall otherwise consent in writing, Pledgor:

         (a)      Maintenance of Register. Will cause the Borrower to maintain
at all times a register at its chief place of business and chief executive
office in which the security interest in the Collateral granted hereby to the
Administrative Agent, to the extent that the same constitutes "uncertificated
securities" (as defined in the Delaware UCC), shall be evidenced.

         (b)      Preservation of Existence, Etc. Will preserve and maintain,
and will cause the Borrower to preserve and maintain, its lawful existence,
rights (charter and statutory), and franchises.

                                       8

<PAGE>   187

         (c)      Compliance with Law. Will comply with all material
Requirements of Law and material Governmental Approvals applicable to it,
except when any such Requirement of Law or Governmental Approval is being
contested in good faith and by appropriate proceedings and for which Acceptable
Reserves have been established.

other than being a limited partner of the Borrower.

         (e)      Jurisdiction of Organization. Will cause the Borrower at all
times to be a limited partnership organized under the laws of the State of
Delaware.

         (f)      Bankruptcy. Will not file a voluntary petition or otherwise
initiate proceedings to have the Borrower adjudicated bankrupt or insolvent, or

of the Borrower as debtor under any applicable federal or state law relating to
bankruptcy, insolvency, or other relief for debtors with respect to the
Borrower; or seek or consent to the appointment of any trustee, receiver,
conservator, assignee, sequestrator, custodian, liquidator (or other similar
official) of the Borrower or of all or any substantial part of the properties
and assets of the Borrower, or make any general assignment for the benefit of
creditors of the Borrower, or admit in writing the inability of the Borrower to
pay its debts generally as they become due or declare or effect a moratorium on
the debt of the Borrower or take any action in furtherance of any action;

discharged all taxes, assessments and governmental charges or levies lawfully
imposed upon it or upon any of its respective income or profits or upon any of
the Portfolio Assets or the Collateral and all lawful claims or obligations
that, if unpaid, would become a Lien upon the Collateral (as defined in the
Credit Agreement), whether real or personal, the Collateral (as defined in this
Agreement) or upon any part thereof. The Pledgor shall have the right, however,
to contest in good faith the validity or amount of any such tax, assessment,
charge or levy by proper proceedings, and may permit the taxes, assessments,
charges or levies so contested to remain unpaid during the period of such
contest if: (a) the Pledgor diligently prosecutes such contest in good faith
and by appropriate proceedings and has established Acceptable Reserves; (b)
during the period of such contest, the enforcement of any contested item is
effectively stayed; and (c) the failure to pay or comply with the contested
item could not reasonably be expected to result in a material adverse effect on
the Collateral.

                  (iii) hold regular partnership meetings, as appropriate, to

                  (iv)  hold itself out to creditors and the public as a legal
                  entity separate and distinct from any other Person;

                  (v)    prepare separate tax returns and financial statements,

                  identity of which the Pledgor has actual knowledge;

                  (x)    not to identify itself in writing as a division of any
                  other Person; and

                  (xi)   to maintain adequate capital in light of its
                  contemplated business operations.

         (i)      Assets. Will not own or acquire any asset other than the
Collateral and Distributions permitted by the Financing Documents.

         (j)      Indebtedness. Will not incur Indebtedness other than

         Section 13.    Administrative Agent. Bank of America, N.A. has been
appointed by the Secured Parties to act as the Administrative Agent hereunder.
Pledgor hereby appoints the Administrative Agent as Pledgor's attorney-in-fact,
with full authority in the place and stead of Pledgor and in the name of
Pledgor or otherwise, from time to time in the Administrative Agent's
discretion at any time that an Event of Default shall have occurred and be
continuing, to take any action and to execute any instrument which the
Administrative Agent may deem necessary or advisable to accomplish the purposes
of this Agreement, including, without limitation, to ask, demand, collect, sue
for, recover, compound, receive and give acceptance and receipts for moneys due
and to become due under or in connection with the Collateral, to receive,
indorse, and collect any drafts or

                                       10

<PAGE>   189

other instruments, documents and chattel paper in connection therewith, and to
file any claims or take any action or institute any proceedings which the
Administrative Agent may deem to be necessary or desirable for the collection
thereof or to enforce compliance with the terms and conditions of the
Partnership Agreement. Such appointment is coupled with an interest and is
irrevocable.

         Section 14.    Administrative Agent May Perform. If Pledgor fails to
perform any agreement contained herein, the Administrative Agent may itself
perform, or cause performance of, such agreement, and the expenses of the
Administrative Agent incurred in connection therewith shall be payable by
Pledgor under Section 20(b).

         Section 15.    The Administrative Agent's Duties. The powers conferred
on the Administrative Agent hereunder are solely to protect its interest in the
Collateral and shall not impose any duty upon it to exercise any such powers.
Except for the safe custody of any Collateral in its possession and the
accounting for moneys actually received by it hereunder, the Administrative
Agent shall have no duty as to any Collateral or as to the taking of any
necessary steps to preserve rights against prior parties or any other rights
pertaining to any Collateral and no such duties shall be implied as arising
hereunder.

         Section 16.    Remedies.  If any Event of Default shall have occurred
and be continuing, subject to Section 9 and compliance with Requirements of
Law:

         (a)      The Administrative Agent may exercise any and all rights and
remedies of Pledgor under or in connection with the Partnership Agreement, the
Partnership Interests or otherwise in respect of the Collateral, including,
without limitation, any and all rights of Pledgor to demand or otherwise
require payment of any amount under, or performance of any provision of, the
Partnership Agreement and all rights of Pledgor to control the operation of the
Borrower.

         (b)      All payments received by Pledgor under or in connection with
the Partnership Agreement, the Partnership Interests, or otherwise in respect
of the Collateral shall be received in trust for the benefit of the
Administrative Agent, shall be segregated from other funds of Pledgor and shall
be forthwith paid over to the Administrative Agent in the same form as so
received (with any necessary endorsement).

         (c)      Any Collateral repossessed by the Administrative Agent under
or pursuant to this Section 16 or any other provision hereof, and any other
Collateral whether or not so repossessed by the Administrative Agent, may be
sold, assigned, leased or otherwise disposed of under one or more contracts or
as an entirety, and without the necessity of gathering at the place of sale the
property to be sold, and in general in such manner, at such time or times, at
such place or places and on such terms as the Administrative Agent may, upon
written direction in compliance with any mandatory requirements of any
Requirement of Law, determine to be commercially reasonable. Any such
disposition which shall be a private sale or other private proceeding permitted
by such requirements shall be made upon not less than 10 days' written notice
to Pledgor specifying the time at which such disposition is to be made and the
intended sale price or other consideration therefor, and shall be subject, for
the 10 days after the giving of such notice, to the right

                                       11

<PAGE>   190

of the Pledgor or any nominee of Pledgor to acquire the Collateral involved at
a price or for such other consideration at least equal to the intended sale
price or other consideration so specified. To the extent permitted by
Requirements of Law, the Administrative Agent on behalf of the Lenders may bid
for and become the purchaser of the Collateral or any item thereof, offered for
sale in accordance with this Section 16. If, under mandatory requirements of
any Requirement of Law, the Administrative Agent shall be required to make
disposition of the Collateral within a period of time which does not permit the
giving of notice to Pledgor as hereinabove specified, the Administrative Agent
need give Pledgor only such notice of disposition as shall be reasonably
practicable in view of such mandatory requirements of any Requirement of Law.

         (d)      All payments made under or in connection with, or proceeds
realized from, the Partnership Agreement, the Partnership Interests, or
otherwise in respect of the Collateral and received by the Administrative
Agent, shall be applied in whole or in part by the Administrative Agent
against, all or any part of the Secured Obligations in accordance with the
terms of the Deposit Account Agreement. Any surplus of such payments held by
the Administrative Agent and remaining after payment in full of all the Secured
Obligations shall be paid over to Pledgor or to whomsoever else may be lawfully
entitled to receive such surplus.

         (e)      Waiver of Claims. Except as otherwise provided in this
Agreement, PLEDGOR HEREBY WAIVES, TO THE EXTENT PERMITTED BY APPLICABLE
REQUIREMENTS OF LAW, NOTICE AND JUDICIAL HEARING IN CONNECTION WITH THE
ADMINISTRATIVE AGENT TAKING POSSESSION OR THE ADMINISTRATIVE AGENT'S
DISPOSITION OF ANY OF THE COLLATERAL, IN EACH CASE AS PERMITTED BY APPLICABLE
REQUIREMENTS OF LAW, INCLUDING, WITHOUT LIMITATION, ANY AND ALL PRIOR NOTICE
AND HEARING FOR ANY PREJUDGMENT REMEDY OR REMEDIES AND ANY SUCH RIGHT WHICH
PLEDGOR WOULD OTHERWISE HAVE UNDER THE CONSTITUTION OR ANY STATUTE OF THE
UNITED STATES OR ANY POLITICAL SUBDIVISION OF ANY SUCH JURISDICTION, and
Pledgor hereby further waives:

                  (i)   all damages occasioned by such taking of possession
                  except any damages which are the direct result of the gross
                  negligence or willful misconduct of either of the
                  Administrative Agent or any Person acting on its behalf or
                  instruction;

                  (ii)  all other requirements as to the time, place and terms
                  of sale or other requirements with respect to the enforcement
                  of the Administrative Agent's rights hereunder; and

                  (iii) all rights of redemption, appraisement, valuation,
                  stay, extension or moratorium now or hereafter in force under
                  any Requirements of Law in order to prevent or delay the
                  enforcement of this Agreement (including, without limitation,
                  any right to claim that such enforcement should be stayed
                  pending the outcome of any other action or proceeding
                  (including

                                       12

<PAGE>   191

                  any arbitration proceeding)) or the absolute sale of the
                  Collateral or any portion thereof, and Pledgor, for itself
                  and all who may claim under it, insofar as it or they now or
                  hereafter lawfully may, hereby waives the benefit of all such
                  Requirements of Law.

Any sale of, or the grant of options to purchase, or any other realization
upon, any Collateral shall, to the extent permitted by Requirements of Law,
operate to divest all right, title, interest, claim and demand, either at law
or in equity, of Pledgor therein and thereto, and shall be a perpetual bar both
at law and in equity against Pledgor and against any and all Persons claiming
or attempting to claim the Collateral so sold, optioned or realized upon, or
any part thereof, from, through and under Pledgor.

         Section 17.    Application of Proceeds. Notwithstanding any other
provision of this Agreement, all moneys collected by the Administrative Agent
upon any sale or other disposition of the Collateral pursuant to Section 16,
together with all other moneys received by the Administrative Agent hereunder,
shall be applied in accordance with the Deposit Account Agreement.

         Section 18.    Remedies Cumulative. No failure or delay on the part of
the Administrative Agent or any Secured Party in exercising any right, power or
privilege hereunder or under any other Financing Document and no course of
dealing between Pledgor and the Administrative Agent or any Secured Party shall
operate as a waiver thereof; nor shall any single or partial exercise of any
right, power or privilege hereunder or under any other Financing Document
preclude any other or further exercise thereof or the exercise of any other
right, power or privilege hereunder or thereunder. The rights, powers and
remedies herein or in any other Financing Document expressly provided are
cumulative and not exclusive of any rights, powers or remedies which the
Administrative Agent or any Secured Party would otherwise have. No notice to or
demand on Pledgor in any case shall entitle Pledgor to any other or further
notice or demand in similar or other circumstances or constitute a waiver of
the rights of the Administrative Agent or any Secured Party to any other or
further action in any circumstances without notice or demand.

         Section 19.    Discontinuance of Proceedings. In case the
Administrative Agent shall have instituted any proceeding to enforce any right,
power or remedy under this Agreement by foreclosure, sale or otherwise, and
such proceeding shall have been discontinued or abandoned for any reason or
shall have been determined adversely to the Administrative Agent, then and in
every such case Pledgor, the Administrative Agent and each holder of any of the
Secured Obligations shall be restored to their former positions and rights
hereunder with respect to the Collateral subject to the security interest
created under this Agreement, and all rights, remedies and powers of the
Administrative Agent shall continue as if no such proceeding had been
instituted.

         Section 20.    Indemnity and Expenses. (a) Pledgor agrees to indemnify
and hold harmless the Administrative Agent and each Secured Party from and
against any and all claims, losses and liabilities arising out of or resulting
from the Collateral or Pledgor's pledge and assignment under this Agreement
(including, without limitation, enforcement

                                       13

<PAGE>   192

against Pledgor of this Agreement), except claims, losses or liabilities
resulting from the Administrative Agent's or any Secured Party's gross
negligence or willful misconduct.

         (a)      Pledgor will upon demand pay to the Administrative Agent or
any Secured Party the amount of any and all reasonable expenses, including the
reasonable fees and expenses of its counsel and of any experts and agents,
which the Administrative Agent or any Secured Party may incur in connection
with (i) the administration of this Agreement, (ii) the sale of, collection
from, or other realization upon, any of the Collateral of Pledgor, (iii) the
exercise or enforcement (whether through negotiations, legal proceedings or
otherwise) of any of the rights of the Administrative Agent or any Secured
Party hereunder against Pledgor or (iv) the failure by Pledgor to perform or
observe any of the provisions hereof.

         Section 21.    Security Interest Absolute The obligations of Pledgor
under this Agreement are independent of the Secured Obligations, and a separate
action or actions may be brought and prosecuted against Pledgor to enforce this
Agreement, irrespective of whether any action is brought against the Borrower,
any other pledgor or any guarantor of the Secured Obligations or whether the
Borrower, any other pledgor or any guarantor of the Secured Obligations is
joined in any such action or actions. All rights of the Administrative Agent
and the assignment, hypothecation and security interest hereunder, and all
obligations of Pledgor hereunder, shall be absolute and unconditional, to the
extent permitted by applicable law, irrespective of:

         (a)      any lack of validity or enforceability of this Agreement, the
Credit Agreement, any other Financing Document or any other agreement or
instrument relating to any thereof, the absence of any action to enforce the
same, any release of the Borrower or Pledgor, the recovery of any judgment
against the Borrower or Pledgor, any action to enforce the same or any other
circumstance which might otherwise constitute a legal or equitable discharge or
defense of Pledgor;

         (b)      any occurrence or condition whatsoever, including without
limitation, (i) any compromise, settlement, release, waiver, renewal,
extension, indulgence or modification of, or any change in, any of the
obligations of the Borrower or Pledgor contained in this Agreement, the Credit
Agreement or any other Financing Document, (ii) any impairment, modification,
release or limitation of the liability of the Borrower or Pledgor or any of
their estates in bankruptcy, or any remedy for the enforcement thereof,
resulting from the operation of any present or future provision of any
applicable bankruptcy law, as amended, or other statute or from the decision of
any court, (iii) the assertion or exercise by Pledgor, the Administrative Agent
or any other Secured Party of any rights or remedies, (iv) the assignment or
the purported assignment of any property as security for the Secured
Obligations, including all or any part of the rights of Pledgor under this
Agreement, (v) the extension of the time for payment by the Borrower or any
other guarantor of any payments or other sums or any part thereof owing or
payable under any of the terms and provisions of any Financing Document or of
the time for performance by the Borrower or Pledgor of any other obligations
under or arising out of any terms or provisions or the extension of the renewal
of any thereof, (vi) the modification or amendment (whether material or
otherwise) of any duty, agreement or

                                       14

<PAGE>   193

obligation of the Borrower or Pledgor set forth in any Financing Document,
(vii) the voluntary or involuntary liquidation, dissolution, sale or other
disposition of all or substantially all of the assets, marshalling of assets
and liabilities, receivership, insolvency, bankruptcy, assignment for the
benefit of creditors, reorganization, arrangement, composition or readjustment
of, or other similar proceeding affecting the Borrower or Pledgor or any of
their respective assets, or the disaffirmancy of this Agreement or any
Financing Document in any such proceeding, (viii) the release or discharge of
the Borrower or Pledgor from the performance or observance of any agreement,
covenant, term or condition contained in any of such instruments by operation
of law, (ix) the unenforceability of this Agreement or any Financing Document
or (x) any other circumstance which might otherwise constitute a legal or
equitable discharge of a surety or guarantor; or

         (c)      any exchange, release or non-perfection of any collateral, or
any release or amendment or waiver of or consent to departure from any other
guarantee, for all or any of the Secured Obligations.

         Section 22.    Amendment; Waiver. No amendment or waiver of any
provision of this Agreement shall be effective unless the same shall be
undertaken and accomplished in accordance with the requirements of Section 9.02
of the Credit Agreement. No delay on the part of any Secured Party in the
exercise of any right, power or remedy shall operate as a waiver thereof, nor
shall any single or partial waiver by such Secured Party of any right, power or
remedy preclude any further exercise thereof, or the exercise of any other
right, power or remedy.

         Section 23.    Addresses for Notices. All notices, requests and other
communications to Pledgor or the Administrative Agent shall be in writing
(including bank wire, cable, telex, telecopy or similar teletransmission or
writing) and shall be given, in the case of Pledgor to its address, or telex,
cable or telecopy number set forth on the signature page hereof, and in the
case of the Administrative Agent, to it at its address, or telex, cable or
telecopy number set forth in Annex II to the Credit Agreement or such other
address or telex, cable or telecopy number as each party may hereafter specify
by notice to such other party. Each such notice, request or other communication
shall be effective (i) if given by telex, when such telex is transmitted to the
telex number specified on the signature page hereof or in Annex II, as the case
may be, and the appropriate answerback is received, (ii) if given by telecopy,
when such telecopy is transmitted to the telecopy number specified on the
signature page hereof or in Annex II, as the case may be, and receipt thereof
is confirmed in writing, or (iii) if given by any other means (including,
without limitation, by air courier), when delivered at the address specified on
the signature page hereof or in Annex II, as the case may be.

         Section 24.    Continuing Assignment, Pledge and Security Interest,
Transfer of Note. This Agreement shall create a continuing pledge, assignment
of, hypothecation of and security interest in the Collateral and shall (i)
remain in full force and effect until no Lender shall have any Commitment
outstanding, and until the Notes, together with interest, and all other Secured
Obligations are indefeasibly paid in full, (ii) be binding upon Pledgor, its
successors and assigns, provided, that Pledgor may not transfer or

                                       15

<PAGE>   194

assign any or all of its rights or obligations hereunder without the prior
written consent of each Lender, and (iii) inure to the benefit of, and be
enforceable by, the Administrative Agent, the Secured Parties and their
respective successors, transferees and assigns. Without limiting the generality
of the foregoing clause (iii), any Secured Party may assign or otherwise
transfer all or any portion of its rights in the Secured Obligations to the
extent and in the manner provided in the Credit Agreement, and such assignee
shall thereupon become vested with all the benefits in respect thereof granted
to such Secured Party herein or otherwise. Upon the indefeasible payment in
full of the Secured Obligations and the expiration or termination of the
Commitments, the security interest granted hereby shall terminate and all
rights to the Collateral shall revert to Pledgor. Upon any such termination,
the Administrative Agent will, at Pledgor's expense, execute and deliver to
Pledgor such documents including UCC termination statements as Pledgor shall
reasonably request to evidence such termination.

         Section 25.    Severability. Any provision hereof that is prohibited
or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof and without affecting the validity
or enforceability of any provision in any other jurisdiction.

         Section 26.    GOVERNING LAW; TERMS. THIS AGREEMENT SHALL BE GOVERNED
BY AND INTERPRETED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK OTHER
THAN ANY SUCH REQUIREMENT OF LAWS THAT WOULD APPLY THE LAWS OF ANOTHER
JURISDICTION, EXCEPT TO THE EXTENT THAT THE LAWS OF ANOTHER JURISDICTION ARE
MANDATORILY APPLICABLE AND EXCEPT TO THE EXTENT THAT THE VALIDITY OR PERFECTION
OF THE SECURITY INTEREST HEREUNDER, OR REMEDIES HEREUNDER, IN RESPECT OF ANY
PARTICULAR COLLATERAL ARE GOVERNED BY THE LAWS OF A JURISDICTION OTHER THAN THE
STATE OF NEW YORK. UNLESS OTHERWISE DEFINED HEREIN OR IN THE CREDIT AGREEMENT,
TERMS USED IN ARTICLE 9 OF THE NY UCC ARE USED HEREIN AS THEREIN DEFINED. ANY
DISPUTE ARISING OUT OF, CONNECTED WITH, RELATED TO, OR INCIDENTAL TO THE
RELATIONSHIP ESTABLISHED BETWEEN THE PLEDGOR AND EACH SECURED PARTY IN
CONNECTION WITH THIS AGREEMENT AND THE OTHER FINANCING DOCUMENTS, AND WHETHER
ARISING IN CONTRACT, TORT, EQUITY OR OTHERWISE, SHALL BE RESOLVED IN ACCORDANCE
WITH THE INTERNAL LAWS (AS OPPOSED TO THE CONFLICTS OF LAWS PROVISIONS) AND
DECISIONS OF THE STATE OF NEW YORK.

         Section 27.    CONSENT TO JURISDICTION; WAIVER OF JURY TRIAL. (a)
PLEDGOR AND EACH SECURED PARTY AGREE THAT ALL DISPUTES BETWEEN THEM ARISING OUT

BE RESOLVED ONLY BY STATE OR FEDERAL COURTS

<PAGE>   195

LOCATED IN NEW YORK, NEW YORK, BUT PLEDGOR AND EACH SECURED PARTY ACKNOWLEDGE
THAT ANY APPEALS FROM THOSE COURTS MAY HAVE TO BE HEARD BY A COURT LOCATED
OUTSIDE OF NEW YORK, NEW YORK. PLEDGOR WAIVES IN ALL DISPUTES ANY OBJECTION
THAT IT MAY HAVE TO THE LOCATION OF THE COURT CONSIDERING THE DISPUTE
INCLUDING, WITHOUT LIMITATION, ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON
THE GROUNDS OF FORUM NON CONVENIENS.

         (a)      PLEDGOR AND THE SECURED PARTIES EACH WAIVE ANY RIGHT TO HAVE
A JURY PARTICIPATE IN RESOLVING ANY DISPUTE, WHETHER SOUNDING IN CONTRACT,
TORT, OR OTHERWISE ARISING OUT OF, CONNECTED WITH, RELATED TO OR INCIDENTAL TO
THE RELATIONSHIP ESTABLISHED BETWEEN THEM IN CONNECTION WITH THIS AGREEMENT AND
THE OTHER FINANCING DOCUMENTS. INSTEAD, ANY DISPUTES RESOLVED IN COURT WILL BE
RESOLVED IN A BENCH TRIAL WITHOUT A JURY.

         Section 28.    Execution in Counterparts. This Agreement may be
executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed shall be deemed to be an
original and all of which taken together shall constitute one and the same
instrument.

         Section 29.    Limitation on Recourse. The obligations of Pledgor
hereunder are obligations solely of Pledgor and shall not constitute a debt or
obligation of any direct or indirect partner or shareholder of Pledgor or any
of their respective directors, officers, agents or employees (each such Person,
a "Non-Recourse Party"). No Non-Recourse Party shall be liable for any amount
payable by Pledgor under this Agreement and the Secured Parties shall not seek
a money judgment or deficiency or personal judgment against any Non-Recourse
Party for payment of the indebtedness payable by Pledgor evidenced by this
Agreement. No property or assets of any Non-Recourse Party, other than as
provided in the Financing Documents, shall be sold, levied upon or otherwise
used to satisfy any judgment rendered in connection with any action brought
against Pledgor with respect to this Agreement or the other Financing
Documents. The foregoing acknowledgments, agreements and waivers shall be
enforceable by any Non-Recourse Party. Notwithstanding the foregoing, nothing
in this Section shall limit or affect or be construed to limit or affect the
obligations and liabilities of any Credit Party or any other Non-Recourse Party
(a) in accordance with the terms of any Transaction Document or Financing
Document creating such liabilities and obligations to which such Credit Party
or Non-Recourse Party is a party, (b) arising from liability pursuant to
applicable Requirements of Law for such Credit Party's or such Non-Recourse
Party's fraudulent actions, knowing misrepresentations or willful misconduct or
(c) with respect to amounts distributed to it in violation of Section 6.10 of
the Credit Agreement.

(i) agree to enter into such further instruments as may be reasonably necessary
or desirable to obligate the Mortgagor to make any applicable additional
payments and (ii) the Mortgagor shall make all such additional payments, except

any Lease or its respective Rents to anyone other than to the Mortgagee.

Mortgaged Property or any interest therein in any manner or way, whether
voluntarily or involuntarily (other than resulting from a taking), or engage in
any common, cooperative, joint, time-sharing or other congregate ownership of
all or part thereof. Notwithstanding the foregoing, the Mortgagor may enter into
leases, subleases and licenses encumbering the Mortgaged Property without the
consent of the Mortgagee provided that such leases, subleases or licenses (i)
are not material to the Mortgagor's business conducted upon the Mortgaged
Property, and (ii) are expressly subordinated and made subject to this Mortgage
and the other Security Documents.

Mortgagor will, at the sole cost of the Mortgagor and without expense to the
Mortgagee, do, execute, acknowledge and deliver all such further acts, deeds,
conveyances, deeds of trust, assignments, notices of assignment, transfers and
assurances as the Mortgagee shall from time to time reasonably require for the
better assuring, conveying, assigning, transferring and confirming unto the
Mortgagee the property and rights hereby conveyed or assigned or intended now or
hereafter so to be, or which the Mortgagor may be or may hereafter become bound

         Section 2.16 Additions to Mortgaged Property. All right, title and
interest of the Mortgagor in and to all extensions, improvements, betterments,
renewals, substitutes and replacements of, and all additions and appurtenances
to, the Mortgaged Property hereafter acquired by or released to the Mortgagor or
constructed, assembled or placed by the Mortgagor upon the Premises or the
Improvements, and all conversions of the security constituted thereby,
immediately upon such acquisition, release, construction, assembling, placement
or conversion, as the case may be, and in each such case without any further
mortgage, conveyance, assignment or other act by the Mortgagor, shall become
subject to the liens and security interests of this Mortgage as fully and
completely and with the same effect as though now owned by the Mortgagor and
specifically described in the grant of the Mortgaged Property above, but at any
and all times the Mortgagor will execute and deliver to the Mortgagee any and
all such further assurances, deeds of trust, conveyances or assignments thereof
as the Mortgagee may reasonably require for the purpose of expressly and
specifically subjecting the same to the liens and security interests of this
Mortgage.

         Section 2.17 No Claims Against the Mortgagee. Nothing contained in this
Mortgage shall constitute any consent or request by the Mortgagee, express or
implied, for the performance of any labor or services or the furnishing of any
materials or other property in respect of the Mortgaged Property or any part
thereof, nor as giving the Mortgagor any right, power or authority to contract

claim against the Mortgagee in respect thereof.

law (a) deducting or allowing the Mortgagor to deduct from the value of the
Mortgaged Property for the purpose of taxation any lien or security interest
thereon or (b) subjecting the Mortgagee to any tax (other than Income Taxes) or
changing the basis of taxation of mortgages, deeds of trust, or other liens or
debts secured thereby, or the manner of collection of such taxes, in each such
case, so as to affect this Mortgage, the Obligations or the Mortgagee, and the
result is to increase the taxes imposed upon or the cost to the Mortgagee of
maintaining the Obligations, or to reduce the amount of any payments receivable
hereunder, then, and in any such event, the Mortgagor shall, on demand, pay to
the Mortgagee additional amounts to compensate for such increased costs or
reduced amounts, provided that if any such payment or reimbursement shall be
unlawful, or taxable to the Mortgagee, or would constitute usury or render the
Obligations wholly or partially usurious under applicable law, then the
Mortgagee may, at its option, declare the Obligations immediately due and
payable or require the Mortgagor to pay or reimburse the Mortgagee for payment
of the lawful and non-usurious portion thereof.

                                   ARTICLE III
                              DEFAULTS AND REMEDIES

         Section 3.01 Events of Default. It shall be an Event of Default under
this Mortgage if any Event of Default (as defined in the Credit Agreement) shall
exist under the Credit Agreement, or, without notice or any opportunity to cure,
the delivery by or on behalf of the

                                       13
<PAGE>   213

Mortgagor of a notice pursuant to 42 Pa. C.S.A. Section 8143 et seq., as
amended, electing to limit the indebtedness secured by this Mortgage.

         Section 3.02 Demand for Payment. Upon the occurrence and during the
continuance of any Event of Default, in addition to any other rights and
remedies Mortgagee may have pursuant to the Financing Documents, or as provided
at law or in equity, and without limitation, the Obligations and all other
amounts payable with respect to this Mortgage shall become due and payable as
provided in the Credit Agreement. The Mortgagor shall pay to the Mortgagee upon
demand all such amounts and such further amounts as shall be reasonably incurred
(without regard to statutory presumption) to cover the costs and expenses of
collection, including reasonable attorneys' fees, disbursements and expenses
incurred by the Mortgagee. Mortgagor hereby waives notice of presentment,
demand, protest, acceleration and notice of acceleration. In case the Mortgagor
shall fail forthwith to pay such amounts or any amounts due under any provision
of this Mortgage upon the Mortgagee's demand, the Mortgagee, in addition to any
other rights or remedies provided herein or at law or equity, shall be entitled
and empowered to institute an action or proceedings at law or in equity as
advised by counsel for the collection of the sums so due and unpaid, to
prosecute any such action or proceedings to judgment or final decree, to enforce
any such judgment or final decree against the Mortgagor and to collect, in any
manner provided by law, all moneys adjudged or decreed to be payable.

         Section 3.03 Possession

         (a) If an Event of Default shall occur and be continuing, the Mortgagee
may enter into possession of the Mortgaged Property, with or without legal
action, and by force if necessary; collect therefrom all rentals (which term
shall also include sums payable for use, operation and occupation, and all
profits, issue and proceeds related thereto) and, after deducting all costs of
collection and administration expense, apply the net rentals to any one or more
of the following items in such manner and in such order of priority as
Mortgagee, in Mortgagee's sole discretion, may elect: the payment of any sums
due under any prior lien, taxes, water and sewer rents, charges and claims,
insurance premiums and all other carrying charges, and to the maintenance,
repair or restoration of the Mortgaged Property, and on account and in reduction
of the principal and interest, or both, hereby secured; in and for that purpose
Mortgagor hereby assigns to Mortgagee all rentals due and to become due under
any lease or leases or rights to use and occupation of the Mortgaged Property
hereafter created, as well as all rights and remedies provided in such lease or
leases or at law or in equity for the collection of the rentals. If for any
reason after such action has been commenced it shall be discontinued or
suspended, or possession of the Mortgaged Property shall remain in or be
restored to Mortgagor, Mortgagee shall have the right for the same Event of
Default or any subsequent Event of Default to bring an amicable action in
ejectment before or after the institution of proceedings to foreclose this
Mortgage or to enforce the Notes, or other Financing Document, or after a
sheriff's sale or judicial sale or other foreclosure sale of the Mortgaged
Property in which Mortgagee is the successful bidder, it being the understanding
of the parties that the authorization to pursue such proceedings for obtaining
possession is an essential part of the remedies for enforcement of the Mortgage
and shall survive any execution sale to Mortgagee. The foregoing warrant shall
not be deemed to have been exhausted by any single exercise thereof, whether or
not any such exercise shall be held by any Court to be invalid, voidable or
void, but may be exercised from time to

                                       14
<PAGE>   214

time, as often as Mortgagee shall elect, until all sums payable or that may
become payable by Mortgagor have been paid in full.

         (b) The Mortgagor will pay to the Mortgagee, upon demand, all
reasonable expenses of obtaining such judgment or decree, including compensation
to the Mortgagee's attorneys (for reasonable fees actually incurred (not as
imposed by statute)) and agents with interest thereon at the Default Interest
Rate; and subject to the limitations set forth in Section 1.03, all such
expenses and compensation shall, until paid, be secured by this Mortgage.

         (c) If an Event of Default shall occur and be continuing, the Mortgagee
may hold, store, use, operate, manage and control the Mortgaged Property,
conduct the business thereof and, from time to time, (i) make all necessary,
proper and reasonable maintenance, repairs, renewals, replacements, additions,
betterments and improvements thereto and thereon, (ii) purchase or otherwise
acquire additional fixtures, personalty and other property, (iii) insure or keep
the Mortgaged Property insured, (iv) manage and operate the Mortgaged Property
and exercise all the rights and powers of the Mortgagor to the same extent as
the Mortgagor could in its own name or otherwise with respect to the same or (v)
enter into any and all agreements with respect to the exercise by others of any
of the powers herein granted to the Mortgagee, all as may from time to time be
directed or determined by the Mortgagee to be in its best interest and the
Mortgagor hereby appoints the Mortgagee as its true and lawful attorney-in-fact
and agent, for the Mortgagor and in its name, place and stead, in any and all
capacities, to perform any of the foregoing acts. Regardless of whether or not
Mortgagee has entered or taken possession, the Mortgagee may receive and, so
long as any Event of Default exists, collect and receive all the Rents, issues,
profits and revenues from the Mortgaged Property, including those past due as
well as those accruing thereafter, and, after deducting (i) all expenses of
taking, holding, managing and operating the Mortgaged Property (including
compensation for the services of all persons employed for such purposes), (ii)
the costs of all such maintenance, repairs, renewals, replacements, additions,
betterments, improvements, purchases and acquisitions, (iii) the costs of
insurance, (iv) such taxes, assessments and other similar charges as the
Mortgagee may at its option pay, (v) other proper charges upon the Mortgaged
Property or any part thereof and (vi) the reasonable compensation, expenses and
disbursements of the attorneys and agents of the Mortgagee, the Mortgagee shall
apply the remainder of the moneys and proceeds so received first to the payment
of the Mortgagee for the payment in full and satisfaction of the Obligations,
and second, if there is any surplus, to the Mortgagor, subject to the
entitlement of others thereto under applicable law.

         (d) Whenever, before any sale of the Mortgaged Property under Section
3.06 hereof, all Obligations that are then due shall have been paid and all
Events of Default fully cured, the Mortgagee will surrender possession of the
Mortgaged Property back to the Mortgagor, its successors or assigns. The same
right of taking possession shall, however, arise again if any subsequent Event
of Default shall occur and be continuing.

         Section 3.04 Right to Cure the Mortgagor's Failure to Perform. Upon the
occurrence and during the continuance of an Event of Default, at any time and
without notice, should the Mortgagor fail in the payment, performance or
observance of any term, covenant or condition required by this Mortgage or the
Credit Agreement or any other Financing Document (with respect to the Mortgaged
Property), the Mortgagee may pay, perform or observe the same, and,

                                       15
<PAGE>   215

subject to the limitations set forth in Section 1.03, all payments made or costs
or expenses incurred by the Mortgagee in connection therewith shall be secured
hereby and shall be, without demand, immediately repaid by the Mortgagor to the
Mortgagee with interest thereon at the Default Interest Rate. The Mortgagee
shall make the determination as to the necessity for any such actions and of the
amounts to be paid. Subject to the notice provisions of the first sentence of
this Section 2.04, to the maximum extent permitted by Requirements of Law, the
Mortgagee is hereby empowered to enter and to authorize others to enter upon the
Premises or the Improvements or any part thereof for the purpose of performing
or observing any such defaulted term, covenant or condition without having any
obligation to so perform or observe and without thereby becoming liable to the
Mortgagor, to any person in possession holding under the Mortgagor or to any
other person.

         Section 3.05 Right to a Receiver. If an Event of Default shall occur
and be continuing the Mortgagee, upon application to a court of competent
jurisdiction, shall be entitled as a matter of right to the appointment of a
receiver to take possession of and to operate the Mortgaged Property and to
collect and apply the Rents. The Mortgagor hereby consents to such appointment
and acknowledges and agrees that the Mortgagee shall be entitled to such
appointment without notice and without regard for the adequacy of security for
the Obligations or the solvency of the Mortgagor or any party liable for the
Obligations and without regard to the then value of the Mortgaged Property and
without regard to whether the Mortgagor has committed waste or allowed
deterioration of the Mortgaged Property; and the Mortgagee or an agent of the
Mortgagee may be appointed as such receiver. The receiver shall have all of the
rights and powers permitted under the laws of the Commonwealth of Pennsylvania.
The Mortgagor will pay to the Mortgagee upon demand all expenses, including
receiver's fees, reasonable attorneys' fees and disbursements that are actually
incurred (not as imposed by statute), costs and agent's compensation incurred
pursuant to the provisions of this Section 3.05; and, subject to the limitations
set forth in Section 1.03, all such expenses shall be secured by this Mortgage
and shall be, without demand, immediately repaid by the Mortgagor to the
Mortgagee with interest thereon at the Default Interest Rate.

         Section 3.06 Foreclosure and Sale

         (a) If an Event of Default shall occur and be continuing, the Mortgagee
may elect to sell the Mortgaged Property or any part of the Mortgaged Property
by exercise of the power of foreclosure or of sale granted to the Mortgagee by
applicable law, this Mortgage or the Security Agreement. In such case, the
Mortgagee may commence one or more actions to foreclose this Mortgage at law or
in equity, or the Mortgagee may proceed and sell the Mortgaged Property, in
accordance with applicable law, to satisfy any Obligation. The Mortgagee or an
officer appointed by a judgment of foreclosure to sell the Mortgaged Property,
may sell all or such parts of the Mortgaged Property as may be chosen by the
Mortgagee in its sole discretion at the time and place of sale fixed by it in a
notice of sale, either as a whole or in separate lots, parcels or items as the
Mortgagee shall deem expedient, and in such order as it may determine, at public
auction to the highest bidder. The Mortgagee or an officer appointed by a
judgment of foreclosure to sell the Mortgaged Property may postpone any
foreclosure or other sale of all or any portion of the Mortgaged Property by
public announcement at such time and place of sale, and from time to time as
permitted by applicable law thereafter may postpone such sale by public
announcement or subsequently noticed sale. Except as otherwise required by
Requirements of

                                       16
<PAGE>   216

Law, without further notice, the Mortgagee or an officer appointed to sell the
Mortgaged Property may make such sale at the time fixed by the last
postponement, or may, in its discretion, give a new notice of sale. Any person,
including the Mortgagor or the Mortgagee or any designee or affiliate thereof,
may purchase any portion of the Mortgaged Property at such sale.

         (b) The Mortgaged Property may be sold subject to unpaid taxes and the
Permitted Encumbrances and other Permitted Liens, and after deducting all the
costs, fees and expenses of the Mortgagee, including, without limitation, costs
of evidence of title in connection with the sale, the Mortgagee or an officer
that makes any sale shall apply the proceeds of sale in the manner set forth in
Section 3.08 hereof.

         (c) Any foreclosure or other sale of less than the whole of the
Mortgaged Property or any defective or irregular sale made hereunder shall not
exhaust the power of foreclosure or of sale provided for herein; and subsequent
sales may be made hereunder until the Obligations have been satisfied, or the
entirety of the Mortgaged Property has been sold. All sums collected by the
Mortgagee under this Mortgage or other Financing Documents or under the Notes on
account of principal or interest or other amounts owing hereunder including,
without limitation, costs of collection and attorneys' fees, may be applied in
such order and manner as the Mortgagee, in its sole discretion, may elect.

         (d) If an Event of Default shall occur and be continuing, the Mortgagee
may instead of, or in addition to, exercising the rights described in Section
3.06(a) above and either with or without entry or taking possession as herein
permitted and as permitted by applicable Requirements of Law, proceed by a suit
or suits in law or in equity or by any other appropriate proceeding or remedy
(i) to specifically enforce payment of some or all of the terms of the Financing
Documents or the performance of any term, covenant, condition or agreement of
this Mortgage or any other right or (ii) to pursue any other remedy available to
it, at law or in equity, all as the Mortgagee shall determine most effectual for
such purposes.

         Section 3.07 Other Remedies

         (a) In case an Event of Default shall occur and be continuing, the
Mortgagee may also exercise, to the extent not prohibited by applicable law, any
or all of the remedies available to a secured party under the UCC, including, to
the extent not prohibited by applicable Requirements of Law, the following:

                  (i)      In the case of personal property, exercise those
         rights and remedies under other applicable Security Documents.

                  (ii)     To make such payments and do such acts as the
         Mortgagee may deem necessary to protect its security interest in the
         Personal Property including paying, purchasing, contesting or
         compromising any encumbrance, charge or lien that is prior or superior
         to the security interest granted hereunder, and, in exercising any such
         powers or authority, paying all expenses incurred in connection
         therewith.

                  (iii)    To enter upon any or all of the Premises or
         Improvements to exercise the Mortgagee's rights hereunder.

                                       17
<PAGE>   217

         (b) In connection with a sale of the Mortgaged Property and the
application of the proceeds of sale as provided in Section 3.08 of this
Mortgage, the Mortgagee shall be entitled to enforce payment of and to receive
up to the principal amount of the Obligations, plus all other charges, payments
and costs due under this Mortgage, and to recover a deficiency judgment for any
portion of the aggregate principal amount of the Obligations remaining unpaid,
with interest.

         Section 3.08 Application of Sale of Proceeds and Rents

         (a) After any foreclosure sale of all or any of the Mortgaged Property,
the Mortgagee shall receive the proceeds of sale, no purchaser shall be required
to see to the application of the proceeds and the Mortgagee shall apply the
proceeds of the sale together with any Rents that may have been collected and
any other sums that then may be held by the Mortgagee under this Mortgage in
accordance with the Deposit Account Agreement.

         (b) Upon any sale of the Mortgaged Property by the Mortgagee (including
pursuant to a power of sale granted by statute or under a judicial proceeding),
the receipt of the Mortgagee or of the officer making the sale shall be a
sufficient discharge to the purchaser or purchasers of the Mortgaged Property so
sold and such purchaser or purchasers shall not be obligated to see to the
application of any part of the purchase money paid over to the Mortgagee or such
officer or be answerable in any way for the misapplication thereof.

         Section 3.09 The Mortgagor as Tenant Holding Over. If the Mortgagor
remains in possession of any of the Mortgaged Property after any foreclosure
sale by the Mortgagee, at the Mortgagee's election the Mortgagor shall be deemed
a tenant holding over and shall forthwith surrender possession to the purchaser
or purchasers at such sale or be summarily dispossessed or evicted according to
provisions of law applicable to tenants holding over.

         Section 3.10 Waiver of Appraisement, Valuation, Stay, Extension and
Redemption Laws

         (a) The Mortgagor will not object to any sale of the Mortgaged Property
pursuant hereto, and for itself and all who may claim under it, the Mortgagor
waives, to the extent that it lawfully may, all right to have the Mortgaged
Property marshalled or to have the Mortgaged Property sold as separate estates,
parcels, tracts or units in the event of any foreclosure of this Mortgage.

         (b) To the full extent permitted by applicable Requirements of Law,
neither the Mortgagor nor anyone claiming through or under it shall or will set
up, claim or seek to take advantage of any appraisement, valuation, stay,
extension, homestead-exemption or redemption laws now or hereafter in force in
order to prevent or hinder the enforcement or foreclosure of this Mortgage, the
absolute sale of the Mortgaged Property or the final and absolute putting of the
purchasers into possession thereof immediately after any sale; and the
Mortgagor, for itself and all who may at any time claim through or under it,
hereby waives to the full extent that it may lawfully do so, the benefit of all
such laws and any and all right to have the assets covered by the security
interest created hereby marshalled upon any foreclosure of this Mortgage.

         Section 3.11 Discontinuance of Proceedings. In case the Mortgagee shall
proceed to enforce any right, power or remedy under this Mortgage by
foreclosure, entry or otherwise, and

                                       18
<PAGE>   218

such proceedings shall be discontinued or abandoned for any reason, or shall be
determined adversely to the Mortgagee, then and in every such case the Mortgagor
and the Mortgagee shall be restored to their former positions and rights
hereunder, and all rights, powers and remedies of the Mortgagee shall continue
as if no such proceeding had been taken.

         Section 3.12 Suits to Protect the Mortgaged Property. During the
continuance of an Event of Default, the Mortgagee shall have power (a) to
institute and maintain suits and proceedings to prevent any impairment of the
Mortgaged Property by any acts which may be unlawful or in violation of this
Mortgage, (b) to preserve or protect its interest in the Mortgaged Property and
in the Rents arising therefrom and (c) to restrain the enforcement of or
compliance with any legislation or other governmental enactment, rule or order
that may be unconstitutional or otherwise invalid if the enforcement of or
compliance with such enactment, rule or order that may be unconstitutional or
otherwise invalid if the enforcement of or compliance with such enactment, rule
or order would impair the security or be prejudicial to the interest of the
Mortgagee hereunder.

         Section 3.13 Filing Proofs of Claim. In case of any receivership,
insolvency, bankruptcy, reorganization, arrangement, adjustment, composition or
other proceedings affecting the Mortgagor, the Mortgagee shall, to the extent
permitted by applicable Requirements of Law, be entitled to file such proofs of
claim and other documents as may be necessary or advisable in order to have the
claims of the Mortgagee allowed in such proceedings for the Obligations secured
by this Mortgage at the date of the institution of such proceedings and for any
interest accrued, late charges and additional interest or other amounts due or
that may become due and payable hereunder after such date.

         Section 3.14 Possession by the Mortgagee. Notwithstanding the
appointment of any receiver, liquidator or trustee of the Mortgagor, any of its
property or the Mortgaged Property, the Mortgagee shall be entitled, to the
extent not prohibited by applicable law, to remain in possession and control of
all parts of the Mortgaged Property now or hereafter granted under this Mortgage
in accordance with the terms hereof and applicable law.

         Section 3.15 Waiver

         (a) No delay or failure by the Mortgagee to exercise any right, power
or remedy accruing upon or during the continuance of any breach or Event of
Default shall exhaust or impair any such right, power or remedy or be construed
to be a waiver of any such breach or Event of Default or acquiescence therein;
and every right, power and remedy given by this Mortgage to the Mortgagee may be
exercised from time to time and as often as may be deemed expedient by the
Mortgagee. No consent or waiver by the Mortgagee to or of any breach or default
by the Mortgagor in the performance of the Obligations shall be deemed or
construed to be a consent or waiver to or of any other breach or Event of
Default in the performance of the same or any other Obligations by the Mortgagor
hereunder. No failure on the part of the Mortgagee to complain of any act or
failure to act or to declare an Event of Default, irrespective of how long such
failure continues, shall constitute a waiver by the Mortgagee of its rights
hereunder or impair any rights, powers or remedies consequent on any future
Event of Default by the Mortgagor.

                                       19
<PAGE>   219

         (b) Even if the Mortgagee (i) grants some forbearance or an extension
of time for the payment of any sums secured hereby, (ii) takes other or
additional security for the payment of any sums secured hereby, (iii) waives or
does not exercise some right granted herein or under the Financing Documents,
(iv) releases a part of the Mortgaged Property from this Mortgage, (v) agrees to
change some of the terms, covenants, conditions or agreements of any of the
Financing Documents, (vi) consents to the filing of a map, plat or replat
affecting the Premises, (vii) consents to the granting of an easement or other
right affecting the Premises or (viii) makes or consents to an agreement
subordinating the Mortgagee's lien on the Mortgaged Property hereunder; no such
act or omission shall preclude the Mortgagee from exercising any other right,
power or privilege herein granted or intended to be granted in the event of any
breach or Event of Default then made or of any subsequent default; nor, except
as otherwise expressly provided in an instrument executed by the Mortgagee,
shall this Mortgage be altered thereby. In the event of the sale or transfer by
operation of law or otherwise of all or part of the Mortgaged Property, the
Mortgagee is hereby authorized and empowered to deal with any vendee or
transferee with reference to the Mortgaged Property secured hereby, or with
reference to any of the terms, covenants, conditions or agreements hereof, as
fully and to the same extent as it might deal with the original parties hereto
and without in any way releasing or discharging any liabilities, obligations or
undertakings.

         Section 3.16 Remedies Cumulative. No right, power or remedy conferred
upon or reserved to the Mortgagee by this Mortgage is intended to be exclusive
of any other right, power or remedy, and each and every such right, power and
remedy shall be cumulative and concurrent and in addition to any other right,
power and remedy given hereunder or now or hereafter existing at law or in
equity or by statute; may be pursued separately, successively or together
against Mortgagor or the Mortgaged Property, or both, at the sole discretion of
Mortgagee, and may be exercised as often as occasion therefor shall arise. The
delay or failure to exercise any such right or remedy shall in no event be
construed as a waiver or release thereof.

                                   ARTICLE IV
                                  MISCELLANEOUS

         Section 4.01 Partial Invalidity. If any provision hereof or of any of
the other Financing Documents is invalid or unenforceable in any jurisdiction or
under any circumstances, the other provisions hereof or of those Financing
Documents shall remain in full force and effect in such jurisdiction and the
remaining provisions hereof will be liberally construed in favor of the
Mortgagee in order to carry out the provisions hereof and of such other
Financing Documents. The invalidity of any provision of this Mortgage in any
jurisdiction or under any circumstances will not affect the validity or
enforceability of any such provision in any other jurisdiction or under any
other circumstances. If any lien, encumbrance or security interest evidenced or
created by this Mortgage is invalid or unenforceable, in whole or in part, as to
any part of the Obligations, or is invalid or unenforceable, in whole or in
part, as to any part of the Mortgaged Property, such portion, if any, of the
Obligations as is not secured by all of the Mortgaged Property hereunder shall
be paid prior to the payment of the portion of the Obligations and shall, unless
prohibited by applicable laws or unless Mortgagee, in its sole and absolute
discretion, otherwise elects, be deemed to have been first paid on and applied
to payment in full of the

                                       20
<PAGE>   220

unsecured or partially secured portion of the Obligations, and the remainder to
the secured portion of the Obligations.

         Section 4.02 Notices. All notices, requests and other communications to
the Borrower or any Secured Party shall be in writing (including bank wire,
cable, telex, telecopy or similar teletransmission or writing) and shall be
given to such party at its address, or telex, cable or telecopy number set forth
on Annex I hereto or such other address or telecopy number as such party may
hereafter specify by notice to the Administrative Agent and the Mortgagor. Each
such notice, request or other communication shall be effective (i) if given by
telecopy, when such telecopy is transmitted to the telecopy number specified in
Annex I and receipt thereof is confirmed in writing, or (ii) if given by any
other means (including, without limitation, by air courier), when delivered at
the address specified in Annex I.

         Section 4.03 Successors and Assigns. All of the grants, covenants,
terms, provisions and conditions herein shall run with the Premises and the
Improvements and shall apply to, bind and inure to, the benefit of the
successors and permitted assigns of the Mortgagor and the successors and assigns
of the Mortgagee.

         Section 4.04 Counterparts. This Mortgage may be executed in any number
of counterparts and all such counterparts shall together constitute but one and
the same instrument.

         Section 4.05 Satisfaction and Cancellation

         (a) The mortgaging to the Mortgagee of the Mortgaged Property as
security and for the benefit of the Mortgagee created and consummated by this
Mortgage shall be null and void when all the Obligations (other than contingent
liabilities that, by their nature, may accrue after principal and interest the
Obligations have been repaid in full) have been indefeasibly paid in full in
cash in accordance with the terms of the Financing Documents and all Commitments
have been terminated.

         (b) In connection with any termination or release pursuant to paragraph
(a) to the extent applicable, this Mortgage shall be marked "satisfied" by the
Mortgagee, and this Mortgage shall be satisfied of record at the request and at
the expense of the Mortgagor. The Mortgagee shall execute any documents
reasonably requested by the Mortgagor to accomplish the foregoing or to
accomplish any release contemplated by paragraph (a) or (b) of this Section 4.05
and the Mortgagor will pay all costs and expenses, including attorneys' fees and
disbursements actually incurred (not as imposed by statute), incurred by the
Mortgagee in connection with the preparation and execution of such documents.

         Section 4.06 Definitions. As used in this Mortgage, the singular shall
include the plural as the context requires and the following words and phrases
shall have the following meanings: (a) "including" shall mean "including but not
limited to"; (b) "provisions" shall mean "provisions, terms, covenants and/or
conditions"; (c) "lien" shall mean "lien, charge, encumbrance, security
interest, mortgage or deed of trust"; (d) "obligation" shall mean "obligation,
duty, covenant and/or condition"; and (e) "any of the Mortgaged Property" shall
mean "the Mortgaged Property or any part thereof or interest therein." Any act
that the Mortgagee is permitted to perform hereunder may be performed at any
time and from time to

                                       21
<PAGE>   221

time by the Mortgagee or any person or entity designated by the Mortgagee. Any
act which is prohibited to the Mortgagor hereunder is also prohibited to all
lessees of any of the Mortgaged Property. Each appointment of the Mortgagee as
attorney-in-fact for the Mortgagor under the Mortgage is irrevocable, with power
of substitution and coupled with an interest.

         Section 4.07 Other Financing Documents. The Mortgagor acknowledges that
in addition to this Mortgage, other Financing Documents secure the Obligations.
The Mortgagor agrees that the lien of this Mortgage shall be absolute and
unconditional and shall not in any manner be affected or impaired by any acts or
omissions whatsoever of the Mortgagee and, without limiting the generality of
the foregoing, the lien hereof shall not be impaired by any acceptance by the
Mortgagee of any security for or guarantees of any of the Obligations hereby
secured, or by any failure, neglect or omission on the part of the Mortgagee to
realize upon or protect any Obligation hereby secured or any collateral security
therefor including the other Financing Documents. The lien hereof shall not in
any manner be impaired or affected by any release (except as to the property
released), sale, pledge, surrender, compromise, settlement, renewal, extension,
indulgence, alteration, changing, modification or disposition of any of the
Obligations secured or of any of the collateral security therefor, including the
other Financing Documents or of any guarantee thereof, and the Mortgagee may at
its discretion foreclose, exercise any power of sale, or exercise any other
remedy available to it under any or all of the other Financing Documents without
first exercising or enforcing any of its rights and remedies hereunder. Such
exercise of the Mortgagee's rights and remedies under any or all of the other
Financing Documents shall not in any manner impair the Obligations hereby
secured or the lien of this Mortgage and any exercise of the rights or remedies
of the Mortgagee hereunder shall not impair the lien of any of the other
Financing Documents or any of the Mortgagee's rights and remedies thereunder.
The undersigned specifically consents and agrees that the Mortgagee may exercise
its rights and remedies hereunder and under the other Financing Documents
separately or concurrently and in any order that it may deem appropriate, and
the undersigned waives any rights of subrogation. In the event of a conflict
between the terms and provisions of this Mortgage and the Credit Agreement, both
documents shall be read together and construed, to the fullest extent possible,
to be in concert with each other. In the event of a conflict that cannot be so
resolved, the terms and provisions of the Credit Agreement shall control and
govern.

         Section 4.08 Subrogation. This Mortgage is made with full substitution
and subrogation of Mortgagee in and to all covenants and warranties by others
heretofore given or made in respect of the Mortgaged Property or any part
thereof.

         Section 4.09 Mortgagee Powers. Without affecting the liability of any
other Person liable for the payment of any obligations herein mentioned and
without affecting the lien or charge of this Mortgage upon any portion of the
Mortgaged Property not then or theretofore released as security for the full
amount of all unpaid Obligations, from time to time, regardless of consideration
and without notice to or consent by the holder of any subordinate lien,
encumbrance, right, title or interest in or to the Mortgaged Property, Mortgagee
may (a) release any Persons liable for or on any Obligation, (b) extend the
maturity or alter any of the terms of any Obligation, (c) modify the interest
rate payable on the principal balance of the Obligations, (d) grant other
indulgences, (e) release or reconvey, or cause to be released or reconveyed at
any time at Mortgagee's option any parcel, portion or all of the Mortgaged
Property, (f) take or

                                       22
<PAGE>   222

release any other or additional security for any obligations herein mentioned or
(g) make compositions or other arrangements with debtors in relation thereto.

         Section 4.10 Enforceability of Mortgage. This Mortgage is deemed to be
and may be enforced from time to time as an assignment, chattel mortgage,
contract, deed of trust, deed to secure debt, financing statement, real estate
mortgage or security agreement, and from time to time as any one or more
thereof, as is appropriate under applicable laws. A carbon, photographic or
other reproduction of this Mortgage or any financing statement in connection
herewith shall be sufficient as a financing statement for any and all purposes.

         Section 4.11 Amendments. No amendment, modification or waiver of any
provision of this Mortgage and no consent to any departure by the Mortgagor
therefrom shall in any event be effective unless the same shall be in writing
and shall be executed and delivered in accordance with Section 9.02 of the
Credit Agreement, and then such amendment, modification, waiver or consent shall
be effective only in the specific instance and for the specific purpose for
which given.

         Section 4.12 Applicable Law. THIS MORTGAGE SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE COMMONWEALTH OF
PENNSYLVANIA.

         Section 4.13 Limitation of Recourse. The obligations of the Mortgagor
hereunder and under the other Financing Documents are obligations solely of the
Mortgagor and shall not constitute a debt or obligation of any direct or
indirect partner or shareholder of the Mortgagor or any of their respective
directors, officers, agents or employees (each such Person, a "Non-Recourse
Party"). No Non-Recourse Party shall be liable for any amount payable by the
Mortgagor under this Mortgage and the Secured Parties shall not seek a money
judgment or deficiency or personal judgment against any Non-Recourse Party for
payment of the indebtedness payable by the Mortgagor evidenced by this Mortgage.
No property or assets of any Non-Recourse Party other than as contemplated in
the Financing Documents, shall be sold, levied upon or otherwise used to satisfy
any judgment rendered in connection with any action brought against the
Mortgagor with respect to this Mortgage or the other Financing Documents. The
foregoing acknowledgments, agreements and waivers shall be enforceable by any
Non-Recourse Party. Notwithstanding the foregoing, nothing in this Section shall
limit or affect or be construed to limit or affect the obligations and
liabilities of any Credit Party or any other Non-Recourse Party (a) in
accordance with the terms of any Transaction Document or Financing Document
creating such liabilities and obligations to which such Credit Party or
Non-Recourse Party is a party, (b) arising from liability pursuant to applicable
Requirements of Law for such Credit Party's or such Non-Recourse Party's
fraudulent actions, knowing misrepresentations or willful misconduct or (c) with
respect to amounts distributed to it in violation of Section 6.10 of the Credit
Agreement.

         SECTION 6. Covenants. So long as any Lender shall have any Commitment
outstanding, and until the Notes, together with interest, and all other
Obligations are indefeasibly paid in full and the DLC Letter of Credit has been
cancelled or has expired and all amounts drawn thereunder have been indefeasibly
reimbursed in full, the Sponsor covenants and agrees as follows:

         (a)      Corporate Existence. The Sponsor shall preserve and maintain
all of its rights, privileges and franchises necessary or desirable in the
normal conduct of its business, except where the failure to maintain any such
right, privilege or franchise could not reasonably be expected to have a
Material Adverse Effect.

         (b)      Compliance. The Sponsor shall comply in all material respects
with all Requirements of Law, except where the failure to comply could not
reasonably be expected to materially and adversely affect the right or ability
of the Sponsor to fulfill its obligations hereunder.

         (c)      Other Activities. The Sponsor shall not institute against, or
join any other Person in instituting against, the Borrower or the General
Partner any proceeding to adjudicate the Borrower or the General Partner a
bankrupt or insolvent, or seeking liquidation, winding up, reorganization,
arrangement, adjustment, protection, relief, or composition of the Borrower or
the General Partner or any of their respective debts under any laws relating to
bankruptcy, insolvency or reorganization or relief of debtors, or seeking the
entry of an order for relief or the appointment of a receiver, trustee,
custodian or other similar official for the Borrower or the General Partner or
for any substantial part of their respective properties, or consent to any
voluntary commencement by the Borrower or the General Partner of any such
proceeding.

         (d)      Share Transfer Restrictions. The Sponsor shall not sell,
assign, transfer or permit to be sold, assigned or transferred any of the
Capital Stock of the General Partner, whether directly or indirectly, except
pursuant to the terms of the Credit Agreement. Except as set forth in Section
7.09 of the Credit Agreement, nothing in this Agreement or the other Financing
Documents is intended to impose a restriction on the ability of the holders of
the Capital Stock of the Sponsor to sell, assign or transfer such Capital Stock
of the Sponsor.

         (e)      Chief Executive Office. The chief executive office of the
Sponsor is located at the address set forth in Section 10 hereto. The Sponsor
shall not establish a new location for its chief executive office until it shall
have given to the Administrative Agent not less than forty-five (45) days prior
written notice of its intention so to do, clearly describing such new location
and providing such other information in connection therewith as the
Administrative Agent may reasonably request.

         (f)      Payment of Taxes. The Sponsor will, or will cause the General
Partner to, timely pay and discharge or cause to be paid or discharged all
taxes, assessments and governmental charges or levies lawfully imposed upon it
(solely attributable to the operations of the General Partner and the Borrower),
the General Partner, the Borrower or upon any of their respective income or
profits or upon any of the Portfolio Assets or the Collateral and all such
lawful claims or obligations that, if unpaid, would become a Lien upon the
Collateral (as defined in the Credit Agreement), whether real or personal, or
upon any part thereof; provided, that the Sponsor shall

                                       5
<PAGE>   238

have the right to contest in good faith the validity or amount of any such tax,
assessment, charge or levy by proper proceedings, and may permit the taxes,
assessments, charges or levies so contested to remain unpaid during the period
of such contest if: (i) the Sponsor diligently prosecutes such contest in good
faith and by appropriate proceedings and has established Acceptable Reserves;
(ii) during the period of such contest, the enforcement of any contested item is
effectively stayed; and (iii) no Lien has been imposed on or is about to be
imposed on any of the Collateral.

         (g)      Liquidity. Subject to the terms of this subsection (g) below,
until the Obligations have been indefeasibly paid in full and all Commitments
have been terminated, the Sponsor agrees to maintain an amount, determined as of
each April 15, June 30, September 30 and December 31 of each calendar year, of
cash or cash equivalents not less than an amount sufficient to pay all taxes,
liens, assessments, claims and obligations required to be paid by the Sponsor
pursuant to subsection (f) above for the twelve-month period immediately
following the applicable date of determination (the "Required Liquidity Level").
The amounts required to be maintained pursuant to the immediately preceding
sentence shall be in addition to, but without duplication of, any amounts
required to be maintained by the Sponsor in connection with the Indebtedness of
Orion Power New York, L.P. If, upon execution of this Agreement, the Sponsor
does not have cash or cash equivalents in an amount equal to the Required
Liquidity Level, then (i) it will retain, from the proceeds of any issuance of
debt or equity, an amount necessary to cause the Sponsor to meet the estimated
Required Liquidity Level as of the immediately following date of determination;
provided, that, Sponsor shall not be required to use proceeds of an equity
contribution made to it in respect of an identified investment to satisfy the
Required Liquidity Level, and (ii) will retain, as cash or cash equivalents any
and all dividends or distributions received from the General Partner or the
Borrower until it has reached the Required Liquidity Level. Amounts held by the
Sponsor to meet the Required Liquidity Level (x) shall be held free of any Liens
or claims of any Person, (y) shall be held and reserved by the Sponsor solely
for the purpose of complying with its obligations under subsection (f) above in
a segregated account, shall not be commingled with other assets of the Sponsor
or any other Person and shall not be held or used for the satisfaction of other
liabilities or obligations of the Sponsor or the General Partner, and (z) shall
not be held out to any creditor of the Sponsor or General Partner as being
available for paying any liability or obligation of the Sponsor or the General
Partner other than those contemplated by subsection (f) above. Notwithstanding
the foregoing (A) in the event and for as long as indebtedness of the Sponsor
has an Investment Grade Rating, the Sponsor shall not be required to comply with
this subsection (g), and (B) in the event and for as long as the Sponsor
maintains a corporate revolving credit facility that can be used for these
purposes in an amount equal to at least four (4) times the Required Liquidity
Level, is not in default thereunder, and has availability thereunder in an
amount at least equal to twice the Required Liquidity Level, then the Sponsor
shall not be required to maintain cash or cash equivalents in a segragated
account as contemplated by this subsection (g) and for so long as the foregoing
is true and correct, the Sponsor shall be deemed to have met the estimated
Required Liquidity Level without the requirement of any further reserve or other
act.

         SECTION 7. Obligations Absolute, Etc. (a) The obligations of the
Sponsor hereunder to make Equity Contributions constitutes a direct obligation
of the Sponsor to the Borrower and the Administrative Agent, for the benefit of
the Secured Parties, and shall be enforceable by the Borrower or the
Administrative Agent.

<PAGE>   239

         (b)      The obligation of the Sponsor hereunder to make Equity
Contributions hereunder is and shall be absolute and unconditional and is not,
and shall not be, subject to any defense or right of set-off, counterclaim,
deduction, diminution, abatement, recoupment, defense, suspension, deferment or
reduction or any other legal or equitable defense which the Sponsor has or
hereafter may have, against any other person for any reason whatsoever
(including, without limitation, any circumstance which constitutes, or might be
construed to constitute, an equitable or legal discharge of any or all of the
Sponsor's obligations under any of the Transaction Documents, in bankruptcy or
otherwise).

         (c)      The obligations of the Sponsor hereunder shall be absolute and
unconditional irrespective of:

                           (i)      any lack of validity or enforceability of
                  any of the Transaction Documents or any other agreement or
                  instrument relating thereto or to any collateral therefor;

                           (ii)     any change in the time, manner or place of
                  payment of, or in any other term of, any of the Transaction
                  Documents, or any amendment or waiver thereof, or any consent
                  to departure from any of the foregoing agreements;

                           (iii)    any taking, exchange, release or
                  non-perfection of any collateral, or any release or amendment
                  or waiver of or consent to departure from any credit support
                  or guaranty for any of the Transaction Documents;

                           (iv)     any manner of application of any collateral,
                  or proceeds thereof, or any manner of sale or other
                  disposition of any collateral or any other assets of the
                  Borrower;

                           (v)      any failure to pay any taxes which may be
                  payable with respect to the performance of its obligations
                  hereunder by the Sponsor or failure to obtain any
                  authorization or approval from or other action by, or to
                  notify or file with, any governmental authority or regulatory
                  body required in connection with the performance of such
                  obligations by the Sponsor; or

                           (vi)     any impossibility or impracticality of
                  performance, force majeure, any act of any government, or
                  other circumstance which might constitute a defense available
                  to, or a discharge of, the Sponsor or a surety, or any other
                  circumstance, event or happening whatsoever, whether foreseen
                  or unforeseen and whether similar or dissimilar to anything
                  referred to above in this Section.

         (d)      The Sponsor has no right, and shall have no right, to
terminate this Agreement or to be released, relieved or discharged (other than
by full and strict compliance by the Sponsor with the terms hereof) from any
obligation or liability hereunder for any reason whatsoever.

         SECTION 8. Waiver. (a) The Sponsor hereby waives demand, presentment,
notice of acceptance and any other notice with respect to this Agreement and any
requirement that the Administrative Agent or any other Secured Party protect,
secure, perfect or insure any Lien or

                                       7

any property subject thereto or exhaust any right or take any action against the
Borrower or any other Person or any Collateral under the Transaction Documents
or otherwise.

         (b)      The Sponsor hereby waives any and all right it may have to

direct and indirect benefits from the arrangements contemplated by the Equity
Contribution Agreement and the Credit Agreement and that the waivers set forth
in this Section 7 are knowingly made in contemplation of such benefits.

         SECTION 9. Rescission of Payment. To the fullest extent permitted by
all applicable Requirements of Law, this Agreement shall continue to be

part thereof), made or caused to be made by the Sponsor pursuant to this
Agreement, is rescinded or must otherwise be restored or returned to the Sponsor
by any beneficiary of this Agreement upon the insolvency, bankruptcy or
reorganization of any Person or otherwise, all as though such payment has not

         SECTION 10. Separate Undertakings. Without limiting the generality of
any of the foregoing provisions of this Agreement, the Sponsor irrevocably
waives, to the fullest extent permitted by all applicable Requirements of Law
and for the benefit of, and as a separate undertaking with, the Administrative

the Sponsor, as a consequence of this Agreement being nonassumable, rejected or
otherwise not assumed by the Borrower or any trustee or other similar official

as a consequence of this Agreement being terminated or modified, in any
proceeding relating to bankruptcy or insolvency of the Borrower or seeking
liquidation, winding up, reorganization, arrangement, protection, relief or
composition of the Borrower or the debts of the Borrower under any Requirement
of Law relating to bankruptcy, insolvency or reorganization or relief or
protection of debtors, whether such nonassumability, rejection, non-assumption,
termination or modification by reason of this Agreement being held to be an
executory contract or by reason of any other circumstance. If this Agreement

modified, the Sponsor hereby agrees for the benefit of, and as a separate
undertaking with the Administrative Agent, that it will be unconditionally
liable to pay or to cause to be paid to the Administrative Agent, an amount

otherwise not assumed or were otherwise not so terminated or modified, such
amount to be payable to the Administrative Agent, at its address specified in

                                   ARTICLE II
                                  SUBORDINATION

         SECTION 2.1. Subordination. Notwithstanding any provision to the
contrary in any instrument governing the Subordinated Debt, the Company, the
Junior Creditor and each holder from time to time of the Subordinated Debt by
its acceptance thereof likewise agrees that all payments of the Subordinated
Debt shall be subordinate and subject in right of payment to the prior
indefeasible payment in full in cash of all Senior Debt and to any security held
or to be held by the Administrative Agent for the benefit of the Secured Parties
for the payment of the Senior Debt.

         SECTION 2.2. Priority and Payment Over Upon Insolvency and Dissolution.
In the event of (a) any insolvency or bankruptcy case or proceeding or any
receivership, liquidation, reorganization or similar case or proceeding in
connection therewith relative to the Company or its creditors as such or to its
assets, or (b) any liquidation, dissolution or other winding up of the Company,
whether voluntary or involuntary and whether or not involving insolvency or
bankruptcy, or (c) any assignment for the benefit of creditors or other
marshalling of assets and liabilities of the Company, then and in any such event
the holders of the Senior Debt shall be

<PAGE>   256

entitled to receive payment in full in cash or cash equivalents of all amounts
due or to become due on or in respect of all Senior Debt before the holders of
the Subordinated Debt shall be entitled to receive and retain any payment on
account of the principal, interest or other amounts due or to become due on the
Subordinated Debt, and to that end the holders of the Senior Debt shall be
entitled to receive, for application to the payment of the Senior Debt, any
payment or distribution of any kind or character, whether in cash, property or
securities, including any such payment or distribution which may be payable or
deliverable by reason of the payment of any other indebtedness of the Company
which is subordinated to the payment of the Subordinated Debt, which may be
payable or deliverable in respect of the Subordinated Debt in any such case,
proceeding, dissolution, liquidation or other winding up or event. Accordingly,
any payment or distribution of assets of the Company of any kind or character,
whether in cash, property or securities, which would otherwise have been made to
the holders of the Subordinated Debt but for the provisions of this Section 2.2
shall instead be made by the Company or by the trustee in bankruptcy, receiver,
liquidating trustee, custodian, assignee, agent or other Person making payment
or distribution of assets of the Company directly to the holders of the Senior
Debt for application to the payment of all Senior Debt remaining unpaid to the
extent necessary to pay all Senior Debt in full in cash or cash equivalents
after giving effect to any concurrent payment or distribution to or for the
benefit of the holders of the Senior Debt.

         If, notwithstanding the foregoing provisions of this Section 2.2, any
holder of the Subordinated Debt shall have received any payment or distribution
of assets of the Company of any kind or character, whether in cash, property or
securities (other than payments expressly permitted in Section 2.6 hereof),
including any such payment or distribution which may be payable or deliverable
by reason of the payment of any other indebtedness of the Company which is
subordinated to the payment of the Subordinated Debt, before all amounts due or
to become due on or in respect of all Senior Debt have been indefeasibly paid in
full in cash or cash equivalents, then and in such event such payment or
distribution shall be received in trust for the holders of the Senior Debt and
shall be forthwith paid over or delivered by the holder of the Subordinated Debt
receiving the same directly to the holders of the Senior Debt or, to the extent
legally required, to the trustee in bankruptcy, receiver, liquidating trustee,
custodian, assignee, agent or other Person making such payment or distribution
of assets of the Company, for application to the payment of all Senior Debt
remaining unpaid to the extent necessary to pay all Senior Debt in full in cash
or cash equivalents after giving effect to any concurrent payment or
distribution to or for the holders of the Senior Debt.

         For purposes of this Agreement only, the words "cash, property or
securities" shall not be deemed to include shares of stock of, or partnership
interests in, the Company as reorganized or readjusted or unsecured debt
securities of the Company or any other corporation provided for by a plan of
reorganization or readjustment which are subordinated in right of payment to all
Senior Debt which may at the time be outstanding to the same or a greater extent
than the Subordinated Debt is subordinated as provided for in this Agreement.

         SECTION 2.3. Priority and Payment Over Upon Acceleration of the
Subordinated Debt. If any Subordinated Debt is declared due and payable before
the date specified therein as the fixed date on which the principal thereof is
due and payable, then and in such event the holders of the Senior Debt shall be
entitled to receive indefeasible payment in full in cash or cash equivalents of
all amounts due or to become due on or in respect of the Senior Debt before the
holders of the Subordinated Debt shall be entitled to receive and retain any
payment (including

<PAGE>   257

any such payment which may be payable by reason of the payment of any other
indebtedness of the Company which is subordinated to the payment of the
Subordinated Debt) by the Company on account of the principal of, interest on or
any other amount due or to become due on the Subordinated Debt or on account of
the purchase or other acquisition of the Subordinated Debt. Accordingly, any
payment by the Company of any amount which the holders of the Subordinated Debt
would have been entitled to receive and retain but for the provisions of this
Section 2.3 shall instead be made by the Company directly to the holders of the
Senior Debt for application to the payment of all Senior Debt remaining unpaid
to the extent necessary to pay all Senior Debt in full in cash or cash
equivalents after giving effect to any concurrent payment or distribution to or
for the holders of the Senior Debt.

         If, notwithstanding the foregoing provisions of this Section 2.3, any
holder of the Subordinated Debt shall have received any payment (other than any
payment expressly permitted in Section 2.6 hereof), including any payment which
may be payable by reason of the payment of any other indebtedness of the Company
which is subordinated to the payment of the Subordinated Debt, before all
amounts due or to become due on or in respect of the Senior Debt have been paid
in full in cash or cash equivalents, then and in such event such payment shall
be received in trust for the holders of the Senior Debt and shall be forthwith
paid over by the holder of the Subordinated Debt receiving such payment to the
holders of the Senior Debt for application to the payment of all Senior Debt
remaining unpaid to the extent necessary to pay all Senior Debt in full in cash
or cash equivalents after giving effect to any concurrent payment or
distribution to or for the holders of the Senior Debt.

         The provisions of this Section 2.3 above shall not apply to any payment
or distribution with respect to which Section 2.2 would be applicable.

         SECTION 2.4. Payment on Subordinated Debt Suspended When Senior Debt is
in Default. In addition to the limitations on payment of the Subordinated Debt
as set forth in Section 2.6, in the event that any Default or Event of Default
with respect to any Senior Debt shall have occurred and be continuing, then
unless and until such Default or Event of Default shall have been cured or
waived or shall have ceased to exist and any acceleration resulting therefrom
shall have been rescinded or annulled, or in the event any judicial proceeding
shall be pending with respect to any such Default or Event of Default, then no
payment (including any payment which may be payable by reason of the payment of
any other indebtedness of the Company which is subordinated to the payment of
the Subordinated Debt) shall be made by the Company on account of the principal
of or interest on the Subordinated Debt or on account of the purchase or other
acquisition by it of the Subordinated Debt.

         If, notwithstanding the foregoing provisions of this Section 2.4, the
Company shall make any payment or distribution on or with respect to any
Subordinated Debt prohibited by the foregoing provisions of this Section 2.4,
then and in every such event such payment or distribution shall be forthwith
paid over or delivered by the holders of the Subordinated Debt to the
Administrative Agent for the benefit of the Lenders.

         The provisions of this Section 2.4 shall not apply to any payment with
respect of which Section 2.2 or 2.3 would be applicable.

<PAGE>   258

         SECTION 2.5. Obligation to Pay Subordinated Debt Not Impaired;
Provisions to Define Relative Rights. Except as provided in this Article II, the
provisions of this Agreement are and are intended solely for the purpose of
defining the relative rights of the holders of the Subordinated Debt on the one
hand and the holders of the Senior Debt on the other hand. It is and shall be
the intent of the parties that this Subordination Agreement shall constitute a
present assignment by the holders of the Subordinated Debt of their rights to
receive payments or distributions of cash, property and securities of the
Company otherwise payable to the holders of the Subordinated Debt in the
circumstances described in Sections 2.2 and 2.3 hereof. Nothing contained in
this Subordination Agreement, except as set forth in Section 2.4 and Section
2.6, shall (a) impair or affect, as among the Company, its creditors (other than
the holders of the Senior Debt) and the holders of the Subordinated Debt, the
obligation of the Company to pay the holders of the Subordinated Debt the
principal of and interest on the Subordinated Debt as of when the same shall
become due and payable in accordance with their terms, or (b) affect the
relative rights against the Company of the holders of the Subordinated Debt and
the creditors of the Company (other than the holders of the Senior Debt).

         SECTION 2.6. Payments on Subordinated Debt. Subject to the terms of
this Article II and as long as no Default or Event of Default exists in the
Credit Agreement, payments on the Subordinated Debt can be made by the Company
to the Junior Creditor out of cash flow available for Permitted Distributions if
and only if all conditions precedent for a Permitted Distribution as set forth
in the Financing Documents have been met and the Company directs the
Administrative Agent, in writing, to pay cash otherwise available for a
Permitted Distribution under the terms of the Credit Agreement and the Deposit
Account Agreement to the holders of the Subordinated Debt. The Junior Creditor
and the Company hereby agree and acknowledge that the Company's obligations to
repay the principal of, the interest on, and all other obligations incurred by
the Company in connection with, the Subordinated Debt are limited to the
Company's cash flow available for Permitted Distributions pursuant to the terms
of the Financing Documents and actually distributed by the Company (or that
would have been distributed but for a direction to pay the Subordinated Debt as
set forth herein) and that the Company shall have no other means for repaying
such obligations.

                                   ARTICLE III
                         IN FURTHERANCE OF SUBORDINATION

         SECTION 3.1. Restriction on Assignment of Subordinated Debt. The Junior
Creditor and each holder of the Subordinated Debt by its acceptance thereof
agrees not to sell, assign or transfer all or any part of the Subordinated Debt
while any Senior Debt remains unpaid unless such sale, assignment or transfer is
made expressly subject to this Subordination Agreement. The Junior Creditor
represents that no other subordination of the Subordinated Debt is in existence
on the date hereof, and the Junior Creditor agrees that the Subordinated Debt
will not be subordinated to any indebtedness owed to any Person other than the
Lenders.

         SECTION 3.2. Reliance on Subordination. The Junior Creditor and each
holder of the Subordinated Debt by its acceptance thereof consents and agrees
that all Senior Debt shall be

<PAGE>   259

deemed to have been made or incurred in reliance upon the subordination of the
Subordinated Debt pursuant to this Subordination Agreement.

         SECTION 3.3. Actions Against the Company. No holder of the Subordinated
Debt will (a) commence any action or proceeding against the Company to recover
all or any part of such Subordinated Debt or (b) join with any creditor in
bringing any proceeding against the Company under Title 11 of the United States
Code or any other state or federal insolvency statute and until, in each case,
the Senior Debt shall have been indefeasibly paid in full (provided that holders
of the Subordinated Debt may so file concurrently with or after the holders of
the Senior Debt). Except pursuant to Section 2.6, the Junior Creditor and each
other holder of the Subordinated Debt will not ask, demand, sue for, take or
receive from the Company, directly or indirectly, in cash, property or
securities or other property or by set-off or in any other manner (including,
without limitation, from or by way of collateral), payment of all or any part of
the Subordinated Debt unless and until all Senior Debt shall have been
indefeasibly paid in full or the benefits of this sentence waived by or on
behalf of the holder or holders of the Senior Debt.

         SECTION 3.4. Subrogation. Subject to the indefeasible payment in full
in cash or cash equivalents of all Senior Debt, the holders of the Subordinated
Debt shall be subrogated to the extent of the payments or distributions made to
the holders of the Senior Debt pursuant to the provisions of this Agreement
(equally and ratably with the holders of all indebtedness of the Company which
by its express terms is subordinated to indebtedness of the Company
substantially to the extent that the Subordinated Debt is subordinated hereunder
and is entitled to like rights of subrogation) to the rights of the holders of
such Senior Debt to receive payments and distributions of cash, property and
securities applicable to the Senior Debt until the principal of and interest on
the Subordinated Debt and all other obligations, monetary or otherwise, or
liabilities now or hereafter arising related to the Subordinated Debt shall be
paid in full. For purposes of such subrogation, no payments or distributions to
the holders of the Senior Debt of any cash, property or securities to which the
holders of the Subordinated Debt would be entitled but for the provisions of
this Agreement, and no payments over, pursuant to the provisions of Section 2.2
or 2.3, to the holders of the Senior Debt by the holders of the Subordinated
Debt shall, as among the Company, its creditors (other than the holders of
Senior Debt) and the holders of the Subordinated Debt, be deemed to be a payment
or distribution by the Company to or on account of the Senior Debt.

         SECTION 3.5. Proofs of Claim. The Junior Creditor may file such proofs
of claim and other papers or documents or may be necessary or advisable in order
to have the claims of the Junior Creditor allowed in any judicial proceedings
relative to the Company (or any other obligor on the Subordinated Debt,
including any guarantor), its creditors or its property. If the Junior Creditor
files any claim, proof of claim or similar instrument in any judicial proceeding
referred to above and all Senior Debt has not been indefeasibly paid in full in
cash or cash equivalents, the Junior Creditor shall (a) file such claim, proof
of claim or similar instrument on behalf of the Lenders and the other holder or
holders of the Senior Debt as it or such other holder's or holders' interests
may appear and (b) take all such other actions as may be appropriate to insure
that all payments and distributions made in respect of any such proceedings are
made to the Lenders and any other holder or holders of the Senior Debt as it or
their interests may appear.

<PAGE>   260

Any term or provision of this Section 3.5 to the contrary notwithstanding, if
any judicial proceeding referred to above is commenced by or against the
Company, and so long as all Senior Debt has not been paid in full: (a) the
Administrative Agent is hereby irrevocably authorized and empowered (in its own
name or in the name of the Junior Creditor or otherwise), but shall have no
obligation, to demand, sue for, collect and receive every payment or
distribution received in respect of any such proceeding and give acquittance
therefor and to file claims and proofs of claims and (b) the Junior Creditor
shall duly and promptly take, for the account of the Lenders and any other
holders of the Senior Debt, such reasonable action as the Lenders may request
(i) to collect all amounts payable by the Company in respect of the Subordinated
Debt and to file the appropriate claims or proofs of claim in respect of the
Subordinated Debt, (ii) to execute and deliver to the Administrative Agent on
behalf of the Lenders such assignments or other instruments as the Lenders may
request in order to enable the Lenders to enforce any and all claims with
respect to all amounts payable in respect of the Subordinated Debt and (iii) to
collect and receive any and all payments with respect to all amounts payable in
respect of the Subordinated Debt. Until the Senior Debt has been paid in full,
no holder of the Subordinated Debt will (in any proceeding of the type described
in Section 2.2) discharge all or any portion of the obligations of the Company
in respect of the Subordinated Debt, whether by forgiveness, receipt of capital
stock, exercise of conversion privileges or otherwise, without the prior consent
of the holders of the Senior Debt.

         SECTION 3.6. Certain Proceedings. Each holder of the Subordinated Debt
agrees that, as between themselves and the holders of the Senior Debt, the
latter shall be deemed to be the "holders" of all claims in respect of the
Subordinated Debt in any proceeding of the type contemplated by clause (a), (b)
or (c) of Section 2.2 (each, a "bankruptcy proceeding"). To the extent not
deemed to be "not in good faith" within the meaning of 11 U.S.C. Section
1126(e), each holder of the Subordinated Debt agrees to vote to accept a plan of
reorganization or dissolution in respect of the Company which the holders of the
Senior Debt have accepted or have notified the holders of the Subordinated Debt
of their intent to accept. If such acceptance by the holders of the Subordinated
Debt is or might (in the sole judgment of the holders of the Senior Debt) cause
the claims of the holders of the Subordinated Debt to be designated under 11
U.S.C. Section 1126(e), then, each holder of the Subordinated Debt agrees not to
vote against a plan of reorganization or dissolution which the holders of the
Senior Debt have accepted or have notified the holders of the Subordinated Debt
of their intent to accept. Any such vote for any plan or abstention from voting
against any plan pursuant to the immediately two preceding sentences shall be
enforceable by the holders of the Senior Debt against the holders of the
Subordinated Debt regardless of whether such plan allows a class subordinated to
the claims of the Subordinated Debt to retain an interest in the Company or
whether the holders of the Subordinated Debt will receive or retain under such
plan on account of their claims in respect of the Subordinated Debt property
having value less than the amount that such holders would receive or retain if
the Bankruptcy Proceeding were under Chapter 7 of the federal Bankruptcy Code.

                                   ARTICLE IV
                                  MISCELLANEOUS

         SECTION 4.1. Changes. The Administrative Agent, on behalf of the
Lenders, may at any time, and from time to time, without the consent of or
notice to the Junior Creditor or to any other holder of the Subordinated Debt,
without incurring responsibility to the Junior Creditor or such holder, and
without impairing or releasing any of the Lender's rights, or any of the
obligations of the Junior Creditor or other holders of the Subordinated Debt
hereunder:

                  (a)      change the time, amount, manner, place or terms of
         payment, or change or extend the time of payment of, or renew or
         otherwise alter, the Credit Agreement or any other Financing Document
         or any instrument or agreement evidencing any Senior Debt or securing
         payment thereof or relating to the Senior Debt in any manner;

                  (b)      sell, exchange, release or otherwise deal with any
         collateral for all or any of the Senior Debt (whether or not in a
         commercially reasonable manner);

                  (c)      release anyone liable in any manner for the payment
         or collection of any Senior Debt;

                  (d)      exercise or refrain from exercising any rights
         against the Company or others (including the Junior Creditor);

                  (e)      apply any sums received by the Administrative Agent
         or any Lenders, by whomsoever paid and however realized, to the payment
         of the Senior Debt in such manner as the Administrative Agent, in its
         sole discretion, shall deem appropriate; and

                  (f)      take any other action which might otherwise
         constitute a defense available to, or a discharge of, the Junior
         Creditor in respect of the Subordinated Debt in respect of these
         provisions.

         SECTION 4.2. Continued Effectiveness. The terms of this Subordination
Agreement shall continue to be effective or be reinstated, as the case may be,
if at any time any payment of any of the Senior Debt is rescinded or must
otherwise be returned by the Lenders or other holder of the Senior Debt upon the
insolvency, bankruptcy or reorganization of the Company or otherwise, all as
though such payment had been due but not made at such time.

         SECTION 4.3. Notices. All notices, requests and demands to or upon the
respective parties hereto to be effective shall be in writing and delivered by
U.S. mail, hand delivery, telecopier or overnight delivery service and, unless
otherwise expressly provided herein, shall be deemed to have been duly given or
made when (i) received, if delivered by hand, telecopier, or overnight delivery
service, (ii) three Business Days after deposit in the mail, first class postage
prepaid, if by U.S. Mail or (iii) in all cases, immediately, whenever delivery
is refused irrespective of the manner, method or means of refusal, addressed as
set forth on the signature

<PAGE>   262

pages hereto or to such other address as may be hereafter notified by the
respective parties hereto and any future holders of the Notes.

         SECTION 4.4. No Waivers. No failure or delay by the Administrative
Agent or the Lenders in exercising any right, power or privilege hereunder or
under the Credit Agreement or any other instrument evidencing or securing any
Obligation shall operate as a waiver thereof nor shall any single or partial
exercise thereof preclude any other or further exercise thereof or the exercise
of any other right, power or privilege. The rights and remedies herein provided
shall be cumulative and not exclusive of any rights or remedies provided by law.

         SECTION 4.5. Amendments and Waivers. Any provision of this
Subordination Agreement may be amended or waived if, but only if, such amendment
or waiver is in writing and is signed by the Administrative Agent, the Junior
Creditor and the Company.

         SECTION 4.6. Successors and Assigns. Subject to Section 3.1, the
provisions of this Agreement shall be binding upon and inure to the benefit of
the parties hereto and their respective successors and assigns.

         SECTION 4.7. Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND
INTERPRETED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK OTHER THAN ANY
SUCH REQUIREMENT OF LAWS THAT WOULD APPLY THE LAWS OF ANOTHER JURISDICTION,
EXCEPT TO THE EXTENT THAT THE LAWS OF ANOTHER JURISDICTION ARE MANDATORILY
APPLICABLE. ANY DISPUTE ARISING OUT OF, CONNECTED WITH, RELATED TO, OR
INCIDENTAL TO THE RELATIONSHIP ESTABLISHED BETWEEN THE PARTIES HERETO IN
CONNECTION WITH THIS AGREEMENT AND THE OTHER FINANCING DOCUMENTS, AND WHETHER
ARISING IN CONTRACT, TORT, EQUITY OR OTHERWISE, SHALL BE RESOLVED IN ACCORDANCE
WITH THE INTERNAL LAWS (AS OPPOSED TO THE CONFLICTS OF LAWS PROVISIONS) AND
DECISIONS OF THE STATE OF NEW YORK.

         SECTION 4.8. Counterparts; Effectiveness. This Subordination Agreement
may be signed in any number of counterparts, each of which shall be an original,
with the same effect as if the signatures thereto and hereto were upon the same
instrument. This Subordination Agreement shall become effective when the
Administrative Agent shall have received counterparts hereof signed by all of
the parties hereto.

         IN WITNESS WHEREOF, the parties hereto have caused this Subordination
Agreement to be duly and executed by their respective authorized officers as of

28, 2000, between ORION POWER HOLDINGS, INC., a Delaware corporation (the
"Pledgor"), and BANK OF AMERICA, N.A., as administrative agent for the Secured

with any successor and assigns, the "Administrative Agent").

                                   WITNESSETH:

                  WHEREAS, the Pledgor is the owner of (a) all the issued and
outstanding shares of the Capital Stock of Orion Power MidWest GP, Inc., a
corporation organized and existing under the laws of the State of Delaware (the

Stock of Orion Power MidWest LP, Inc., a corporation organized and existing

                  WHEREAS, the GP Company is the sole general partner in Orion
Power MidWest, L.P., a Delaware limited partnership (the "Borrower") and the LP
Company is the sole limited partner of the Borrower;

                  WHEREAS, the Borrower has entered into a Credit Agreement,
dated as of April 28, 2000 (as the same may be amended, supplemented or

Administrative Agent, Banc of America Securities LLC and Goldman Sachs Credit

available credit facilities to the Borrower to finance a portion of the purchase
price of the Portfolio Assets (as defined in the Credit Agreement) and to
provide revolving credit availability to the Borrower;

                  WHEREAS, the Credit Agreement contemplates the execution,
delivery and the implementation of this Agreement;

                  WHEREAS, it is a condition precedent to the obligations of the
Lenders under the Credit Agreement that this Agreement shall have been entered
into by the

<PAGE>   268

parties hereto and shall have become unconditionally and fully effective in
accordance with the terms hereof; and

                  WHEREAS, the Borrower, the Administrative Agent and the
Lenders have entered into a Deposit Account Agreement, dated as of April 28,
2000 (as the same may be amended, supplemented or otherwise modified from time
to time, the "Deposit Account Agreement"), providing for, among other things,
the establishment of the Accounts and the application of the proceeds of the
Collateral.

                  NOW, THEREFORE, in consideration of the foregoing premises and
for other good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, the parties hereto agree as follows:

                  1.       Definitions: Construction. (a) For the purposes of
this Agreement, (i) capitalized terms not otherwise defined herein shall have
the meanings set forth in Article I of the Credit Agreement, and (ii) the
principles of the construction set forth in such Article I shall apply hereto.

                  (b)      In addition, wherever used in this Agreement and
unless the context otherwise requires, the following terms shall have the
following meanings:

                  "AGREEMENT" shall mean this Stock Pledge Agreement.

                  "COMPANIES" shall mean the collective reference to the LP
Company and the GP Company.

                  "GP COMPANY" shall have the meaning provided in the first
recital to this Agreement.

                  "GP PLEDGED SHARES" shall have the meaning provided in the
first recital to this Agreement.

                  "LP COMPANY" shall have the meaning provided in the first
recital to this Agreement.

                  "PLEDGED COLLATERAL" shall have the meaning specified in
Section 3.1.

                  "PLEDGED SHARES" shall mean the collective reference to the LP
Pledged Shares and the GP Pledged Shares.

                  "SECURED OBLIGATIONS" shall have the meaning provided in
Section 2(a).

                  2.       Security. (a) This Agreement is for the benefit of
the Administrative Agent and the other Secured Parties to secure (i) the prompt
and complete payment and performance when due by the Borrower of all of the
Obligations, including, without limitation, all amounts payable or to become
payable to the Secured Parties by the Borrower under the Financing Documents
when and as the same shall become due and payable (whether by acceleration or
otherwise) in accordance with the terms thereof,

                                       2
<PAGE>   269

and (ii) the due performance and compliance by the Pledgor with the terms hereof
and each other Financing Document to which it is a party (collectively, the
"Secured Obligations"). Without limiting the generality of the foregoing, this
Agreement secures the payment of all amounts which constitute part of the
Secured Obligations and would be owed by the Borrower to the Secured Parties but
for the fact that they are unenforceable or not allowable due to the existence
of a bankruptcy, reorganization or similar proceeding involving any Credit
Party.

                  (b)      The Pledgor understands, agrees and confirms that the
Administrative Agent may enforce this Agreement against it without proceeding
against the Borrower or against any other credit or security for payment of the
Secured Obligations.

                  3.       Pledge of Stock

                  3.1.     Pledge. As collateral security for the prompt and
complete payment and performance when due of the Secured Obligations, the
Pledgor hereby pledges, hypothecates, assigns, transfers and sets over to the
Administrative Agent, grants to the Administrative Agent a security interest of
first priority in, and hereby delivers unto the Administrative Agent (in each
case for the benefit of the Secured Parties) the following (collectively, the
"Pledged Collateral"):

                           (i)      the Pledged Shares and any certificates or
                  instruments representing the Pledged Shares, accompanied by
                  duly executed stock powers in blank, and all cash, securities,
                  dividends and other property at any time in the future and
                  from time to time received, receivable or otherwise
                  distributed, in respect of or in exchange for any or all of
                  the Pledged Shares;

                           (ii)     all securities hereafter delivered to the
                  Administrative Agent in substitution for or in addition to any
                  of the foregoing, any certificates representing or evidencing
                  such securities, and all cash, securities, dividends and other
                  property, at any, time and from time to time received,
                  receivable or otherwise distributed in respect of or in
                  exchange for any or all of the foregoing;

                           (iii)    all other claims of any kind or nature, and
                  any instruments, certificates, chattel paper or other writings
                  evidencing such claims, whether in contract or tort, and
                  whether arising by operation of law, consensual agreement or
                  otherwise, at any time acquired by the Pledgor in respect of
                  any or all of the foregoing collateral against the Companies;
                  and

                           (iv)     all proceeds of any of the foregoing
                  including, without limitation (A) all rights of the Pledgor to
                  receive monies due and to become due under or pursuant to the
                  foregoing collateral; (B) all rights of the Pledgor to receive
                  a return of any insurance premiums or Insurance Proceeds or
                  other proceeds of any indemnity, warranty or guarantee with

                                       3
<PAGE>   270

                  respect to the foregoing collateral, and (C) to the extent not
                  included in the foregoing, all additions to and replacements
                  of the foregoing collateral and all proceeds receivable or
                  received when any and all of the foregoing collateral is sold,
                  collected, exchanged or otherwise disposed whether voluntarily
                  or involuntarily.

                  3.2.     Uncertificated Stock. Notwithstanding anything to the
contrary contained in Section 3.1, if any Pledged Share (whether now owned or
hereafter acquired) is evidenced by an uncertificated security, the Pledgor
shall promptly notify the Administrative Agent thereof and shall promptly take
all actions required to perfect the security interest of the Administrative
Agent under applicable law (including, without limitation, under the Uniform
Commercial Code as adopted in any appropriate jurisdiction). The Pledgor further
agrees to take such actions as the Administrative Agent deems necessary or
desirable to effect the foregoing and to permit the Administrative Agent to
exercise any of its rights and remedies hereunder, and agrees to provide an
opinion of counsel reasonably satisfactory to the Administrative Agent with
respect to any such pledge of uncertificated Pledged Shares promptly upon
request of the Administrative Agent.

                  4.       Appointment of Agents; Endorsements, etc. The
Administrative Agent shall have the right to appoint one or more agents for the
purpose of retaining physical possession of the Pledged Shares and other Pledged
Collateral, which may be held (in the discretion of the Administrative Agent) in
the name of the Pledgor, endorsed or assigned in blank or in favor of the
Administrative Agent or any nominee or nominees of the Administrative Agent or
an agent appointed by the Administrative Agent.

                  5.       Representations, Warranties and Covenants. In order

         (b)      Pledgor has duly executed and delivered this Agreement and

hereunder.

                  5.5.     No Defenses. The Pledgor's obligations under this

maintain all of its rights, privileges and franchises necessary or desirable in

such new location and providing such other information in connection therewith
as the Administrative Agent may reasonably, request and (ii) with respect to
such new location, it shall have taken all action, reasonably satisfactory to
the Administrative Agent, to maintain the security interest of the
Administrative Agent in the Pledged Collateral intended to be granted hereby at
all times fully perfected, of first priority and in full force and effect.

                  5.13.    Payment of Taxes. The Pledgor will, or will cause the
Companies to, timely pay and discharge or cause to be paid or discharged all
taxes, assessments and governmental charges or levies lawfully imposed upon it,
the Companies, the Borrower or upon any of their respective income or profits or
upon any of the Portfolio Assets or

                                       6
<PAGE>   273

the Collateral and all such lawful claims or obligations that, if unpaid, would
become a Lien upon the Collateral (as defined in the Credit Agreement), whether
real or personal, the Pledged Collateral (as defined in this Agreement) or upon
any part thereof; provided, that the Pledgor shall have the right to contest in
good faith the validity or amount of any such tax, assessment, charge or levy by
proper proceedings, and may permit the taxes, assessments, charges or levies so
contested to remain unpaid during the period of such contest if: (a) the Pledgor
diligently prosecutes such contest in good faith and by appropriate proceedings
and has established Acceptable Reserves; (b) during the period of such contest,
the enforcement of any contested item is effectively stayed; and (c) no Lien has
been imposed on or is about to be imposed on any of the Pledged Collateral.

                  5.14.    Liquidity. Subject to the terms of this Section 5.14
below, until the Secured Obligations have been indefeasibly paid in full and all
Commitments have been terminated, the Pledgor agrees to maintain an amount,
determined as of each April 15, June 30, September 30 and December 31 of each
year of the term hereof, of cash or cash equivalents not less than an amount
sufficient to pay all taxes, liens, assessments, liens, claims and obligations
required to be paid by the Pledgor pursuant to Section 5.13 above for the
twelve-month period immediately following the applicable date of determination
(the "Required Liquidity Level"). If, upon execution of this Agreement, the
Pledgor does not have cash or cash equivalents in an amount equal to the
Required Liquidity Level, then (a) it will retain, from the proceeds of any
issuance of debt or equity, an amount necessary to cause the Pledgor to meet the
estimated Required Liquidity Level as of the immediately following date of
determination; provided, that, Pledgor shall not be required to use proceeds of
an equity contribution made to it in respect of an identified investment to
satisfy the Required Liquidity Level, and (b) will retain, as cash or cash
equivalents any and all dividends or distributions received from the Companies
or the Borrower until it has reached the Required Liquidity Level. Amounts held
by the Pledgor to meet the Required Liquidity Level (x) shall be held free of
any Liens or claims of any Person, (y) shall be held and reserved by the Pledgor
solely for the purpose of complying with its obligations under Section 5.13
above in a segregated account, shall not be commingled with other assets of the
Pledgor or any other Person and shall not be held or used for the satisfaction
of other liabilities or obligations of the Pledgor or the Companies, and (z)
shall not be held out to any creditor of the Pledgor or the Companies as being
available for paying any liability or obligation of the Pledgor or the Companies
other than those contemplated by Section 5.13 above. Notwithstanding the
foregoing (i) in the event and for as long as indebtedness of the Pledgor has an
Investment Grade Rating, the Pledgor shall not be required to comply with this
Section 5.14, and (ii) in the event and for as long as the Pledgor maintains a
corporate revolving credit facility that can be used for these purposes in an
amount equal to at least four (4) times the Required Liquidity Level, is not in
default thereunder, and has availability thereunder in an amount at least equal
to twice the Required Liquidity Level, then the Pledgor shall not be required to
maintain cash or cash equivalents in a segragated account as contemplated by
this Section 5.14 and for so long as the foregoing is true and correct, the
Pledgor shall be deemed to have met the estimated Required Liquidity Level
without the requirement of any further reserve or other act.

                  5.15.    Pledged Shares.

                  (a)      The Pledged Shares consist of the number and type of
shares of the Capital Stock of the Companies, as described in Exhibit A. All of
the Pledged Shares are certificated securities.

                  (b)      The Pledged Shares are, and along with any securities
pledged in substitution therefor or in addition thereto will be, duly and
validly issued, fully paid and nonassessable and duly and validly pledged
hereunder in accordance with all applicable Requirements of Law, and the Pledgor
warrants, covenants and agrees to defend the Administrative Agent's right, title
and interest in and to the Pledged Shares and all other Pledged Collateral
against the claims and demands of all Persons whomsoever.

                  (c)      The Pledgor is the record, legal and beneficial owner
of, and has good title to all of the Pledged Shares and all other Pledged
Collateral, free and clear of all Liens and other claims, security interests,
mortgages, pledges and other encumbrances of every nature whatsoever (other than
Permitted Liens) and it has the right to pledge the Pledged Shares and all other
Pledged Collateral as herein provided.

                  (d)      The Pledged Shares constitute, and any securities
pledged in substitution therefor, or in addition thereto shall as of the date
hereof constitute, and shall, except as otherwise permitted hereby or by the
Credit Agreement, at all times constitute, one hundred percent (100%) of all the
issued and outstanding Capital Stock of the Companies. The Companies do not have
outstanding (i) any securities convertible into or exchangeable for their
Capital Stock or (ii) any rights to subscribe for or to purchase, or any options
for the purchase of, or any agreement, or any options for the purchase of, or
any agreement, arrangements or understandings providing for the issuance of its
Capital Stock.

                  (e)      The Pledgor will not authorize the issuance by the
Companies of any additional stock of the Companies, (whether common or preferred
and whether of a class now or hereafter existing) unless concurrently with such
issuance all such stock is owned by Pledgor and made subject to the pledge of
shares hereunder. If the Pledgor shall acquire (by purchase, stock dividend or
otherwise) any additional shares in the Companies at any time or from time to
time after the date hereof, the Pledgor will forthwith pledge and deposit or
cause to be deposited such shares with the Administrative Agent and deliver or
cause to be delivered to the Administrative Agent certificates therefor,
accompanied by stock powers duly executed in blank by the Pledgor, and will
promptly thereafter deliver to the Administrative Agent a certificate executed
by any Responsible Officer of the Pledgor describing such shares and certifying
that the same have been duly pledged with the Administrative Agent hereunder.

                  (f)      Each certificate evidencing the Pledged Shares is,
and any security pledged in substitution therefor or in addition thereto will
be, issued in the name of the Pledgor and each such certificate has been, or
when issued will then have been duly executed in blank or has, or when issued
will then have, attached thereto a stock power substantially in the form of
Exhibit C duly signed in blank by the appropriate officer of

                                       8
<PAGE>   275

the Pledgor. Each such stock power will give the Administrative Agent the rights
and authority it purports to give.

                  (g)      Upon receipt by the Administrative Agent of the stock
certificates representing the Pledged Shares, (which either have been duly
executed in blank or have attached thereto stock powers substantially in the
form of Exhibit C duly signed in blank by the appropriate officer of the
Pledgor), the security interest described in this Agreement will represent a
valid and perfected first priority lien on, and security interest in, the
Pledged Collateral, in favor of the Administrative Agent for the benefit of the
Secured Parties.

                  (h)      The Pledgor has not executed, or authorized and there
does not currently exist, any effective financing statement or other instrument
similar in effect that is on file in any recording office covering all or any
part of the Pledgor's interest in the Pledged Collateral, except such as may
have been filed pursuant to this Agreement or the other Financing Documents,
and, so long as any of the Secured Obligations remain unpaid or any Commitments
remain outstanding, the Pledgor will not execute or authorize to be filed in any
public office any financing statement (or similar statement or instrument of
registration under the law of any jurisdiction) or statements relating to the
Pledged Collateral, except financing statements filed or to be filed in respect
of and covering the security interests granted hereby by the Pledgor. Upon the
completion of all filings and recordings described in Exhibit B, no filings or
recordings (including, without limitation, under the Uniform Commercial Code as
adopted in the State of New York) will be necessary to be made in order to
perfect, protect and preserve the lien on and security interest in the Pledged
Collateral created by this Agreement.

                  (i)      The Pledgor will not hereafter create or permit to
exist any Lien, security interest or other charge, encumbrance or other security
arrangement upon or with respect to, any of the Pledged Collateral (other than
Liens created under this Agreement or Permitted Liens), until the Secured
Obligations are indefeasibly paid or otherwise discharged in full.

                  (j)      None of the Pledged Shares constitutes margin stock,
as defined in Regulation U of the Board of Governors of the Federal Reserve
System.

                  6.       Voting, and Corporate Rights. Unless and until an
Event of Default shall have occurred and be continuing and the Pledgor shall
have been notified by the Administrative Agent of the Secured Parties' written
election to exercise remedies hereunder, the Pledgor shall be entitled to
exercise any voting and corporate rights with respect to the Pledged Shares or
any securities pledged in substitution therefor or in addition thereto for any
purpose, and in any manner, not inconsistent with the terms hereof; provided,
that, no vote shall be cast or any consent, waiver or ratification given or any
action taken which would violate or be inconsistent with any of the terms of
this Agreement, the Credit Agreement or any other Financing Document, and
provided, further, that, the Pledgor shall not exercise or refrain from
exercising any such voting and other rights if it could reasonably be
anticipated that such action would have an adverse effect on the creation,
attachment, perfection or priority of the security interests herein

                                       9
<PAGE>   276

granted in the Pledged Collateral to the Administrative Agent (or any part
thereof). Upon the Pledgor's receipt of a notice in accordance with the first
sentence of this Section 6, and during the continuance of an Event of Default,
all such rights of the Pledgor to vote and to give consents, waivers and
ratifications shall be exercisable solely by the Administrative Agent in
accordance with Section 8.

                  7.       Dividends and Other Distributions. Unless and until
an Event of Default shall have occurred and be continuing, all cash dividends
payable in respect of the Pledged Shares that represent Permitted Distributions
under the terms of the Credit Agreement shall be paid to the Pledgor and shall
not be part of the Pledged Collateral; provided, that, any dividends or
distributions payable in respect of the Pledged Shares made in contravention of
the Credit Agreement or which represent in whole or in part an extraordinary,
liquidating or other distribution in return of capital shall be paid to the
Administrative Agent and retained by it as part of the Pledged Collateral. The
Administrative Agent shall also be entitled at all times to receive directly,
and to retain as part of the Pledged Collateral:

                  (a)      all other or additional stock or securities or
property (other than cash) paid or distributed by way of dividend in respect of
the Pledged Shares;

                  (b)      all other or additional stock or other securities or
property (including cash) paid or distributed in respect of the Pledged Shares
by way of stock-split, spin-off, split-up, reclassification, combination of
shares or similar rearrangement; and

                  (c)      all other or additional stock or other securities or
property, which may be paid in respect of the Pledged Collateral by reason of
any consolidation, merger, exchange of stock, conveyance of assets, liquidation
or similar corporate reorganization.

                  8.       Remedies Upon Default. If an Event of Default shall
have occurred and be continuing, the Administrative Agent, acting pursuant to
and in accordance with the terms and conditions of the Credit Agreement and the
direction of the Required Lenders thereunder, shall be entitled to exercise all
the rights, powers and remedies vested in it (whether vested in it by this
Agreement, the Credit Agreement or any other Financing Document or by law) for
the protection and enforcement of its rights in respect of the Pledged
Collateral and, without limitation of the foregoing, may cause all or any of the
Pledged Shares or other Pledged Collateral to be transferred into its name or
that of a nominee or nominees, and the Pledgor shall, upon the request of the
Administrative Agent, execute such additional instruments and documents as are
necessary to effect such transfer.

                  (a)      In addition, if an Event of Default shall have
occurred and be continuing, the Administrative Agent, acting pursuant to and in
accordance with the terms and conditions of the Credit Agreement and the
direction of the Required Lenders thereunder, without being required to give any
notice to the Pledgor or the Companies (except in respect of actions taken
pursuant to Section 8(a)(i) or Section 8(a)(ii)), shall be entitled to exercise
the following rights, which, the Pledgor agrees, are commercially reasonable:

                                       10
<PAGE>   277

                  (i)      to exercise any and all voting rights with respect to
         the Pledged Shares and other Pledged Collateral, including the
         appointment and removal of any proxy or proxies or substitute or
         substitutes;

                  (ii)     to receive and retain, as collateral security for the
         Secured Obligations, any and all dividends at any time and from time to
         time declared or paid upon any of the Pledged Shares and other Pledged
         Collateral otherwise payable to the Pledgor;

                  (iii)    to accept rights issues;

                  (iv)     to prove in any liquidation or scheme of arrangement
         or any other composition or arrangement with or for creditors whether
         secured or unsecured and whether formed pursuant to the order of any
         court or otherwise, and to give any consent on behalf of the Pledgor in
         relation thereto;

                  (v)      to attend meetings of creditors and vote;

                  (vi)     to compromise claims in relation to or arising out of
         the Pledged Shares;

                  (vii)    to give sufficient receipts and discharges for all
         monies to which the Pledgor is or may become entitled in respect of the
         Pledged Shares or any part thereof or which shall come into the hands
         of the Administrative Agent, which receipts and discharges shall, to
         the maximum extent permitted by Requirements of Law, exonerate the
         Administrative Agent from all liability to see to the application
         thereof or from being answerable for the loss or misapplication
         thereof;

                  (viii)   to execute any documents which it may consider
         expedient, in good faith, in relation to the foregoing as it shall in
         its absolute discretion determine (but without any obligation to
         consult with the Pledgor) in relation to any exercise of any such
         right, power or privilege; and

                  (ix)     to institute, prosecute and defend any proceedings in
         any court or tribunal in respect of any act or transaction referred to
         in this Section 8(a).

                  (b)      (i) Without obligation to resort to other security or
marshal assets for disposition in any particular order or priority whatsoever,
the Administrative Agent shall have the right at any time and from time to time
upon the occurrence and during the continuance of an Event of Default to sell,
resell, assign and deliver, all or any of the Pledged Shares or other Pledged
Collateral, in one or more parcels at the same or different times, and all
rights, titles and interests, claims and demands therein and right of redemption
thereof, on any securities exchange on which the Pledged Shares, any security
pledged in substitution therefor or in addition thereto or any of them may then
be listed, or at public or private sale, for cash, upon credit or for future
delivery, and at such price

                                       11
<PAGE>   278

or prices, on such terms as the Secured Parties (acting pursuant to the Credit
Agreement) may determine and in compliance with such conditions as the Secured
Parties (acting pursuant to the Credit Agreement) may in their absolute
discretion deem advisable, provided such sale is conducted in a commercially
reasonable manner in accordance with applicable law. The Pledgor hereby agrees
that upon such sale, any and all equity or right of redemption, stay or approval
of the Pledgor shall be automatically waived and released without any further
action on the part of the Pledgor, all without either demand, advertisement or
notice (except as required by Requirements of Law), all of which (to the extent
permitted by Requirements of Law) are hereby expressly waived by the Pledgor.

                  (ii)     In the event of any such sale, the Administrative
Agent shall, at least ten (10) Business Days before the sale, give the Pledgor
notice of its intention to sell except that, if any Secured Party shall
determine, in its sole discretion, that any of the Pledged Shares or other
Pledged Collateral threatens to decline quickly in value or to become worthless,
any such sale may be made upon three days' notice to the Pledgor.

                  (iii)    The Administrative Agent agrees that upon the
indefeasible payment and performance in full of the Secured Obligations and the
termination of all Commitments, prior to any such sale, such sale shall be
cancelled.

                  (iv)     Upon each such sale, the Administrative Agent or any
other Secured Party may purchase all or any of the Pledged Shares or other
Pledged Collateral being sold, free from any equity or right of redemption,
which upon each such sale shall, to the extent permitted by Requirements of Law,
be waived and released.

                  (v)      The proceeds of each such sale shall be applied by
the Administrative Agent as provided in Section 11.

                  (vi)     For the purposes of this Section 8(b), an agreement
to sell any or all of the Pledged Shares or other Pledged Collateral entered
into following any Event of Default shall, to the extent permitted by
Requirements of Law, be treated as a sale thereof, and the Administrative Agent
shall be free to carry out such sale pursuant to such agreement and the Pledgor
shall not be entitled to the return of any of the Pledged Shares or other
Pledged Collateral subject thereto notwithstanding the fact that, after the
Administrative Agent shall have entered into any such agreement, the Secured
Obligations shall have been paid in full.

                  (vii)    The Administrative Agent shall not be obligated to
make any sale of the Pledged Collateral if it shall determine not to do so,
regardless of the fact that notice of sale of the Pledged Collateral may have
been given.

                  (viii)   The Administrative Agent, may without notice, adjourn
any public or private sale or cause the same to be adjourned from time to time
by announcement at the time and place fixed for sale, and such sale may, without
further notice, be made at the time and place to which the same was so
adjourned.

                                       12
<PAGE>   279

                  (ix)     In case sale of all or any part of the Pledged
Collateral is made on credit or for future delivery, the Pledged Collateral so
sold may be retained until the sale price is paid by the purchaser or purchasers
thereof, but the Administrative Agent shall not incur any liability in case any
such purchaser or purchasers shall fail to take up and pay for the Pledged
Collateral so sold and, in case of any such failure, such Pledged Collateral may
be sold again upon like notice.

                  (x)      Neither the Administrative Agent nor any other
Secured Party shall be liable for failure to collect or realize upon any or all
of the Pledged Collateral or for any delay in so doing nor shall any of them be
under any obligation to take any action whatsoever with regard thereto.

                  (xi)     As an alternative to exercising the power of sale
herein conferred upon it, the Administrative Agent may proceed by a suit or
suits at law or in equity to foreclose this Agreement and to sell the Pledged
Collateral, or any portion thereof, pursuant to a judgment or decree of a court
or courts of competent jurisdiction.

                  (c)      The Administrative Agent shall have the right, for
and in the name, place and stead of the Pledgor, to execute endorsements,
assignments or other instruments of conveyance or transfer with respect to all
or any of the Pledged Shares and other Pledged Collateral in connection with any
sale thereof in accordance with Section 8(a) or (b).

                  9.       Remedies Cumulative: Indemnification of the
Administrative Agent and the Other Secured Parties. (a) No failure or delay on
the part of the Administrative Agent or any Secured Party in exercising any
right, power or privilege hereunder or under any other Financing Document and no
course of dealing between Pledgor and the Administrative Agent or any Secured
Party shall operate as a waiver thereof; nor shall any single or partial
exercise of any right, power or privilege hereunder or under any other Financing
Document preclude any other or further exercise thereof or the exercise of any
other right, power or privilege hereunder or thereunder. The rights, powers and
remedies herein or in any other Financing Document expressly provided are
cumulative and not exclusive of any rights, powers or remedies which the
Administrative Agent or any Secured Party would otherwise have. No notice to or
demand on Pledgor in any case shall entitle Pledgor to any other or further
notice or demand in similar or other circumstances or constitute a waiver of the
rights of the Administrative Agent or any Secured Party to any other or further
action in any circumstances without notice or demand.

                  (b)      The Pledgor hereby agrees to indemnify and hold
harmless the Administrative Agent and each other Secured Party from and against
any loss, liability or expense (including reasonable fees and disbursements of
counsel for the Administrative Agent and each other Secured Party) which may be
incurred by the Administrative Agent or any other Secured Party (except as a
result of the gross negligence or willful misconduct of any Secured Party) as a
result of or in connection with:

                                       13
<PAGE>   280

                  (i)      any failure of the Pledgor to fulfill its obligations
         under this Agreement, upon demand by the Administrative Agent,
         including, without limitation, costs and expenses of enforcement of any
         obligation of the Pledgor to make any such payment hereunder and any
         other obligation, covenant or agreement of the Pledgor hereunder;

                  (ii)     the enforcement, discharge, improvement and
         protection of the interest of the Administrative Agent hereby created;

                  (iii)    the exercise or attempted exercise of any right,
         authority, power or remedy conferred on the Administrative Agent under
         or by virtue of this Agreement or by statute; and

                  (iv)     the assisting or defending of any right, title or
         interest of the Pledgor or the Administrative Agent or any other
         Secured Party in connection with the Pledged Shares.

                  10.      Obligations Absolute. (a) The obligations of the
Pledgor hereunder shall not be altered or affected by the validity, regularity
or enforceability of any provision of the Credit Agreement or any other
Transaction Document, any compromise, alteration, amendment, modification,
extension, renewal, release or other chance of, or any waiver, consent or other
action in respect of, any of the terms, covenants or conditions of any of such
agreements, the recovery of any judgment against any Person or any action to
enforce the same, any failure or delay in the enforcement of the obligations of
the Borrower under any of the Financing Documents or any other circumstances.
The Pledgor hereby expressly and irrevocably, waives all defenses, setoffs,
counterclaims, recoupments, terminations or impairments whether arising
hereunder or otherwise. The Pledgor hereby covenants that this Agreement shall
not be discharged except by payment and performance in full of the Secured
Obligations.

                  (b)      Without limiting the generality of the foregoing, the
obligations of the Pledgor hereunder and the rights of the Administrative Agent
to enforce the same by proceedings whether by action at law, suit in equity or
otherwise, shall not be in any way affected by (x) any insolvency, bankruptcy,
liquidation, reorganization, readjustment, composition, dissolution, winding up
or other proceeding, involving or affecting the Borrower, the Companies, the
Pledgor or any other Person or (y) any change in the ownership of the Borrower,
the Companies, the Pledgor or any other Person. To the fullest extent permitted
by law, the Pledgor releases and waives any legal or equitable defenses to the
enforceability of its obligations hereunder, and the Pledgor agrees that its
obligations shall be absolute and unconditional and shall not be affected or
discharged by any circumstance, act or event except the indefeasible payment in
full of the Secured Obligations and termination of all Commitments, including,
without limitation, the following:

                  (i)      the exchange, sale or release of any security for the
         Secured Obligations;

                                       14
<PAGE>   281

                  (ii)     the failure to enforce any guaranty or security given
         or promised by any other Person or the waiver, compromise or release of
         such other guaranty or security;

                  (iii)    the extension of time for the performance of any
         obligations in respect of the Secured Obligations or the Pledgor's
         obligations hereunder; or

                  (iv)     the failure to give notice to the Pledgor of any
         nonpayment or other breach in respect of the Secured Obligations.

                  (c)      The Pledgor hereby expressly and irrevocably waives
notice of acceptance of this Agreement, notice of any liability to which it may
apply, presentment, demand, protest, notice of dishonor, non-payment, or
nonperformance, any proceeding to enforce any provision of any Transaction
Document and any right to require a proceeding prior to payment hereunder
against the Borrower or any other Person.

                  11.      Application of Proceeds. Notwithstanding any other
provision of this Agreement, all moneys collected by the Administrative Agent
upon any sale or other disposition of the Pledged Collateral, together with all
other moneys received by the Administrative Agent hereunder, shall be applied in
accordance with the Deposit Account Agreement.

                  12.      Purchasers of Pledged Collateral. Upon any sale of
the Pledged Collateral by the Administrative Agent hereunder (whether by virtue
of the power of sale herein, granted, pursuant to judicial process or
otherwise), the receipt of the Administrative Agent or the officer making the
sale shall be a sufficient discharge to the purchaser or purchasers of the
Pledged Collateral so sold, and such purchaser or purchasers shall not be
obligated to see to the application of any part of the purchase money paid over
to the Administrative Agent or such officer or be answerable in any way for the
misapplication or nonapplication thereof.

                  13.      Continuing Obligation. This Agreement is a continuing
obligation of the Pledgor and shall (a) be binding upon the Pledgor, and upon
the successor and assigns of the Pledgor, (b) inure to the benefit of and be
enforceable by the Administrative Agent and the other Secured Parties and their
respective successors and assigns and (c) remain in full force and effect until
no Lender shall have any Commitment outstanding and until the Notes, together
with interest, and all other Secured Obligations are indefeasibly paid in full.

                  14.      Administrative Agent. Bank of America, N.A. (or any
successor) has been appointed by the Secured Parties to act as the
Administrative Agent hereunder. The Administrative Agent is hereby appointed,
which appointment is irrevocable and coupled with an interest, the
attorney-in-fact of the Pledgor for the purpose of carrying out the provisions
hereof and taking any action and executing any instruments which the
Administrative Agent may deem necessary or advisable to accomplish the purposes
hereof and to do all acts and things which under any of the covenants and
agreements

                                       15
<PAGE>   282

herein contained or implied ought to be done by the Pledgor or which the
Administrative Agent is hereby or by virtue hereof or by statute authorized or
empowered to do.

                  15.      Waiver of Subrogation. Without limiting the
generality of the foregoing, while this Agreement is in effect, the Pledgor
hereby irrevocably waives (a) any rights which it may acquire by way of
subrogation under this Agreement, whether such subrogation rights arise by any
payment made hereunder or any set-off or application of funds of the Pledgor by
the Administrative Agent or otherwise, and (b) any right of reimbursement or
contribution against the Borrower or the Companies or any other security or
guarantee or right of offset held by the Administrative Agent therefor. If,
notwithstanding the preceding sentence, any amount shall be paid to the Pledgor
on account of any subrogation rights in connection with this Agreement at any
time when all of the Secured Obligations shall not have been paid in full, such
amount shall be held by the Pledgor in trust for the Administrative Agent for
the benefit of the Secured Parties, segregated from other funds of the Pledgor,
and shall, forthwith upon receipt by the Pledgor, be turned over to the
Administrative Agent in the exact form received by the Pledgor (duly endorsed
by, the Pledgor to the Administrative Agent, if required), to be applied as
provided in Section 11.

                  16.      Successors and Assigns. This Agreement shall be
binding upon and inure to the benefit of and be enforceable by the respective
successors and assigns of the parties hereto and shall inure to the benefit of
the Secured Parties and their respective successors and assigns; provided, that,
the Pledgor may not assign or transfer any of its rights or obligations
hereunder without the prior written consent of each of the Lenders. The
Administrative Agent may transfer, assign or grant its rights hereunder in
connection with an assignment or transfer of all or any part of its interest in
and rights under the Credit Agreement.

                  17.      Severability. If any term or provision hereof or the
application thereof to any circumstance shall, in any jurisdiction and to any
extent, be invalid or unenforceable, such term or provision shall be ineffective
as to such jurisdiction to the extent of such invalidity or unenforceability
without invalidating or rendering unenforceable the remaining terms and
provisions hereof or the application of such term or provision to circumstances
other than those as to which it is held invalid or unenforceable. To the extent
permitted by applicable law, the parties hereto hereby waive any provision of
law which renders any term or provision invalid or unenforceable in any respect.

                  18.      Notices. All notices, requests and other
communications to the Pledgor or the Administrative Agent shall be in writing
(including telecopy or similar teletransmission or writing) and shall be given
to such party at its address, or telecopy number set forth below or such other
address, or telecopy number as such party may hereafter specify by notice to the

                  (a)      THIS AGREEMENT SHALL BE GOVERNED BY AND INTERPRETED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK OTHER THAN ANY SUCH
REQUIREMENT OF LAWS THAT WOULD APPLY THE LAWS OF ANOTHER JURISDICTION, EXCEPT TO
THE EXTENT THAT THE LAWS OF ANOTHER JURISDICTION ARE MANDATORILY APPLICABLE AND
EXCEPT TO THE EXTENT THAT THE VALIDITY OR PERFECTION OF THE SECURITY INTEREST
HEREUNDER, OR REMEDIES HEREUNDER, IN RESPECT OF ANY PARTICULAR COLLATERAL ARE
GOVERNED BY THE LAWS OF A JURISDICTION OTHER THAN THE STATE OF NEW YORK. UNLESS
OTHERWISE DEFINED HEREIN OR IN THE CREDIT AGREEMENT, TERMS USED IN ARTICLE 9 OF
THE UNIFORM COMMERCIAL CODE AS ADOPTED IN THE STATE OF NEW YORK ARE USED HEREIN
AS THEREIN DEFINED. ANY DISPUTE ARISING OUT OF, CONNECTED WITH, RELATED TO, OR
INCIDENTAL TO THE RELATIONSHIP ESTABLISHED BETWEEN THE PLEDGOR AND EACH SECURED
PARTY IN CONNECTION WITH THIS AGREEMENT AND THE OTHER FINANCING DOCUMENTS, AND
WHETHER ARISING IN CONTRACT, TORT, EQUITY OR OTHERWISE, SHALL BE RESOLVED IN
ACCORDANCE WITH THE INTERNAL LAWS (AS OPPOSED TO THE CONFLICTS OF LAWS
PROVISIONS) AND DECISIONS OF THE STATE OF NEW YORK.

                  (b)      PLEDGOR AND EACH SECURED PARTY AGREE THAT ALL

TO THE RELATIONSHIP ESTABLISHED BETWEEN THEM IN CONNECTION WITH THIS AGREEMENT

<PAGE>   284

FINANCING DOCUMENTS, AND WHETHER ARISING IN CONTRACT, TORT, EQUITY, OR
OTHERWISE, SHALL BE RESOLVED ONLY BY STATE OR FEDERAL COURTS LOCATED IN NEW
YORK, NEW YORK, BUT PLEDGOR AND EACH SECURED PARTY ACKNOWLEDGE THAT ANY APPEALS
FROM THOSE COURTS MAY HAVE TO BE HEARD BY A COURT LOCATED OUTSIDE OF NEW YORK,
NEW YORK. PLEDGOR WAIVES IN ALL DISPUTES ANY OBJECTION THAT IT MAY HAVE TO THE
LOCATION OF THE COURT CONSIDERING THE DISPUTE INCLUDING, WITHOUT LIMITATION, ANY
OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON
CONVENIENS.

                  (c)      PLEDGOR AND THE SECURED PARTIES EACH WAIVE ANY RIGHT
TO HAVE A JURY PARTICIPATE IN RESOLVING ANY DISPUTE, WHETHER SOUNDING IN
CONTRACT, TORT, OR OTHERWISE ARISING OUT OF, CONNECTED WITH, RELATED TO OR
INCIDENTAL TO THE RELATIONSHIP ESTABLISHED BETWEEN THEM IN CONNECTION WITH THIS
AGREEMENT AND THE OTHER FINANCING DOCUMENTS. INSTEAD, ANY DISPUTES RESOLVED IN
COURT WILL BE RESOLVED IN A BENCH TRIAL WITHOUT A JURY.

                  20.      Survival of Agreements. All agreements, statements,
representations and warranties made by the Pledgor herein or in any certificate
or other instrument delivered by the Pledgor or on its behalf under this
Agreement shall be deemed to have been relied upon by the Secured Parties and
shall survive the execution and delivery of this Agreement, the Credit Agreement
and the other Transaction Documents (regardless of any investigation made by the
Secured Parties or on their behalf) until this Agreement is terminated as
expressly set forth in Section 22 hereof.

                  21.      Headings. The section and subsection headings used in
this Agreement are for convenience only and shall not affect the construction of
this Agreement.

                  22.      Termination. On the date of the termination of
Pledgor's obligations hereunder as contemplated by Section 13(c) hereof, this
Agreement shall (except for the provisions of Section 9(b)) terminate, and the
Administrative Agent, at the written request and expense of the Pledgor, will
promptly execute and deliver to the Pledgor the proper instruments acknowledging
the satisfaction and termination of this Agreement, and will promptly duly
assign, transfer and deliver to the Pledgor (without recourse and without any
representation or warranty) free from any Lien granted hereunder all of the
Pledged Shares and other Pledged Collateral which has previously been delivered

<PAGE>   285

                  23.      Execution of Counterparts. This Agreement may be
executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed shall be deemed to be an
original and all of which taken together shall constitute one and the same
instrument.

                  24.      Amendment; Waiver. No amendment or waiver of any
provision of this Agreement shall be effective unless the same shall be
undertaken and accomplished in accordance with the requirements of Section 9.02
of the Credit Agreement. No delay on the part of any Secured Party in the
exercise of any right, power or remedy shall operate as a waiver thereof, nor
shall any single or partial waiver by such Secured Party of any right, power or
remedy preclude any further exercise thereof, or the exercise of any other
right, power or remedy.

                  25.      Further Assurances. The Pledgor hereby agrees, at its
own expense, to execute and deliver, from time to time, any and all further or
other instruments and to perform such acts, as the Administrative Agent or any
other Secured Party may reasonably request to effect the purposes of this
Agreement and to secure to the Administrative Agent and the other Secured
Parties the benefits of all rights, powers and remedies conferred upon the
Administrative Agent by the terms of this Agreement. In the event that at any
time hereafter, due to any change in circumstances, including without
limitation, any change in an applicable law, or any decision hereafter made by a
court construing any applicable law, it is, in the opinion of counsel for any
Secured Party, necessary or desirable to file or record this Agreement or any
Uniform Commercial Code financing, statement or other instrument or document
respecting this Agreement or the pledge made hereunder, the Pledgor agrees to
pay all fees, costs and expenses of such recording, or filing and to execute and
deliver any instruments that may be necessary or appropriate to make such filing
or recording effective.

                  26.      Applicability of the Credit Agreement.
Notwithstanding any other provision of this Agreement, in connection with its
obligations hereunder the Administrative Agent has all of the rights, powers,
privileges, exculpations, protections, and indemnities as are provided for or
referred to in the Credit Agreement.

                  27.      Limitation on Recourse. The obligations of the
Pledgor hereunder are obligations solely of the Pledgor and shall not constitute
a debt or obligation of any direct or indirect partner or shareholder of the
Pledgor or any of their respective directors, officers, agents or employees
(each such Person, a "Non-Recourse Party"). No Non-Recourse Party shall be
liable for any amount payable by the Pledgor under this Agreement and the
Secured Parties shall not seek a money judgment or deficiency or personal
judgment against any Non-Recourse Party for payment of the indebtedness payable
by the Pledgor evidenced by this Agreement. No property or assets of any
Non-Recourse Party, other than as provided in the Financing Documents, shall be
sold, levied upon or otherwise used to satisfy any judgment rendered in
connection with any action brought against the Pledgor with respect to this
Agreement or the other Financing Documents. The foregoing acknowledgements,
agreements and waivers shall be enforceable by any Non-Recourse Party.
Notwithstanding the foregoing, nothing in this

                                       19
<PAGE>   286

Section shall limit or affect or be construed to limit or affect the obligations
and liabilities of any Credit Party or any other Non-Recourse Party (a) in
accordance with the terms of any Transaction Document or Financing Document
creating such liabilities and obligations to which such Credit Party or
Non-Recourse Party is a party, (b) arising from liability pursuant to applicable
Requirements of Law for such Credit Party's or such Non-Recourse Party's
fraudulent actions, knowing misrepresentations or willful misconduct or (c) with
respect to amounts distributed to it in violation of Section 6.10 of the Credit
Agreement.
