                         THE COMMITMENTS AND BORROWINGS

         2.01 REVOLVER FACILITY. (a) Each Revolver Lender severally, but not
jointly, agrees to lend to Borrower such Revolver Lender's Pro Rata Share of one
or more Borrowings under (i) the Acquisition Subfacility (further described in
SECTION 2.01(b) below) not to exceed such Lender's Committed Sum under the
Acquisition Subfacility, and (ii) the Working Capital/Distribution Subfacility
(further described in SECTION 2.01(c) below) not to exceed such Lender's
Committed Sum under the Working Capital/Distribution Subfacility. Such
Borrowings may be repaid and reborrowed from time to time in accordance with the
terms and provisions of the Loan Documents; provided that, each such Borrowing
must occur on a Business Day and no later than the Business Day immediately
preceding the Revolver Maturity Date.

         (b) Loans under the Acquisition Subfacility shall be available to
Borrower for the purposes set forth in SECTION 6.12(b). After giving effect to
any Borrowing under the Acquisition Subfacility, the Acquisition Subfacility
Principal Debt shall not exceed the Acquisition Subfacility Commitment then in
effect.

         (c) Loans under the Working Capital/Distribution Subfacility shall be
available to Borrower for the purposes set forth in SECTION 6.12(c); provided,
however, Borrowings under the Working Capital/Distribution Subfacility will be
available to fund Quarterly Distributions only if, at the time of such Borrowing
and after giving effect thereto, there is at least $9,000,000.00 of the Working
Capital/Distribution Subfacility Commitment undrawn and available for working
capital purposes. After

                                       19
<PAGE>

giving effect to any Borrowing under the Working Capital/Distribution
Subfacility, the Working Capital/Distribution Subfacility Principal Debt shall
not exceed the Working Capital/Distribution Subfacility Commitment then in
effect.

         2.02 TERM LOAN FACILITY. Subject to and in reliance upon the terms,
conditions, representations, and warranties in the Loan Documents, each Term
Loan Lender severally, but not jointly, agrees to lend to Borrower in a single
disbursement on the Conditions Effective Date such Lender's Pro Rata Share of
the Term Loan Commitment. If all or a portion of the Term Loan Principal Debt is
paid or prepaid, then the amount so paid or prepaid may not be reborrowed. Any
portion of the Term Loan Commitment that remains undisbursed after the initial
disbursement under the Term Loan Facility shall be reduced to zero and cancelled
on the date of such initial disbursement.

         2.03 BORROWINGS, CONVERSIONS AND CONTINUATIONS OF LOANS.

         (a) Each Borrowing, each conversion of Loans from one Type to the
other, and each continuation of Loans as the same Type shall be made upon the
Borrower's irrevocable notice to the Administrative Agent, which may be given by
telephone. Each such notice must be received by the Administrative Agent not
later than 11:00 a.m., New York time, (i) three Business Days prior to the
requested date of any Borrowing of, conversion to or continuation of Eurodollar
Rate Loans, (ii) one Business Day prior to the conversion of Eurodollar Rate
Loans to Base Rate Loans, and (iii) on the requested date of any Borrowing of
Base Rate Loans. Each such telephonic notice must be confirmed promptly by
delivery to the Administrative Agent of a written Borrowing Notice,
appropriately completed and signed by an authorized officer of the Borrower.
Each Borrowing of, conversion to or continuation of Eurodollar Rate Loans shall
be in a principal amount of $500,000 or a whole multiple of $500,000 in excess
thereof. Each Borrowing of or conversion to Base Rate Loans shall be in a
principal amount of $500,000 or a whole multiple of $100,000 in excess thereof.
Each Borrowing Notice (whether telephonic or written) shall specify (i) whether
the Borrowing, conversion or continuation (as applicable) is under the Term Loan
Facility or the Revolver Facility, and if it is under the Revolver Facility,
whether it is under the Acquisition Subfacility or the Working
Capital/Distribution Subfacility, (ii) whether the Borrower is requesting a
Borrowing, a conversion of Loans from one Type to the other, or a continuation
of Loans as the same Type, (iii) the requested date of the Borrowing, conversion
or continuation, as the case may be (which shall be a Business Day), (iv) the
principal amount of Loans to be borrowed, converted or continued, (v) the Type
of Loans to be borrowed or to which existing Loans are to be converted, and (vi)
if applicable, the duration of the Interest Period with respect thereto. If the
Borrower fails to specify a Type of Loan in a Borrowing Notice or if the
Borrower fails to give a timely notice requesting a conversion or continuation,
then the applicable Loans shall be made or continued as, or converted to, Base
Rate Loans. Any such automatic conversion to Base Rate Loans shall be effective
as of the last day of the Interest Period then in effect with respect to the
applicable Eurodollar Rate Loans. If the Borrower requests a Borrowing of,
conversion to, or continuation of Eurodollar Rate Loans in any such Borrowing
Notice, but fails to specify an Interest Period, it will be deemed to have
specified an Interest Period of one month.

         (b) Following receipt of a Borrowing Notice, the Administrative Agent
shall promptly notify each Lender of its Pro Rata Share of the applicable Loans,
and if no timely notice of a conversion or continuation is provided by the
Borrower, the Administrative Agent shall notify each Lender of the details of
any automatic conversion to Base Rate Loans described in the preceding
subsection. In the case of a Borrowing, each Lender shall make the amount of its
Loan available to the Administrative Agent in immediately available funds at the
Administrative Agent's Office not later than 1:00 p.m., New York time, on the
Business Day specified in the applicable Borrowing Notice. Upon satisfaction of
the applicable conditions set forth in SECTION 4.02 (and, if such Borrowing is
the initial Borrowing, SECTION 4.01), the

                                       20
<PAGE>

Administrative Agent shall make all funds so received available to the Borrower
in like funds as received by the Administrative Agent either by (i) crediting
the account of the Borrower on the books of Bank of America with the amount of
such funds or (ii) wire transfer of such funds, in each case in accordance with
instructions provided to the Administrative Agent by the Borrower.

         (c) Except as otherwise provided herein, a Eurodollar Rate Loan may be
continued or converted only on the last day of the Interest Period for such
Eurodollar Rate Loan. During the existence of a Default or Event of Default, no
Loans may be requested as, converted to or continued as Eurodollar Rate Loans
without the consent of the Required Lenders, and the Required Lenders may demand
that any or all of the then outstanding Eurodollar Rate Loans be converted
immediately to Base Rate Loans.

         (d) The Administrative Agent shall promptly notify the Borrower and the
Lenders of the interest rate applicable to any Eurodollar Rate Loan upon
determination of such interest rate. The determination of the Eurodollar Rate by
the Administrative Agent shall be conclusive in the absence of manifest error.

         (e) After giving effect to all Borrowings, all conversions of Loans
from one Type to the other, and all continuations of Loans as the same Type,
there shall not be more than ten (10) Interest Periods in effect at any given
time with respect to Loans.

         2.04 PREPAYMENTS.

         (a) Optional Prepayments. The Borrower may, upon notice to the
Administrative Agent, at any time or from time to time voluntarily prepay in
whole or in part the Acquisition Subfacility Principal Debt, the Working
Capital/Distribution Subfacility Principal Debt and/or the Term Loan Principal
Debt without premium or penalty; provided that (i) such notice must be received
by the Administrative Agent not later than 11:00 a.m., New York time, (A) three
Business Days prior to any date of prepayment of Eurodollar Rate Loans, and (B)
on the date of prepayment of Base Rate Loans; (ii) any prepayment of Eurodollar
Rate Loans shall be in a principal amount of $500,000 or a whole multiple of
$500,000 in excess thereof; and (iii) any prepayment of Base Rate Loans shall be
in a principal amount of $500,000 or a whole multiple of $100,000 in excess
thereof. Each such notice shall specify the date and amount of such prepayment,
the Facility (or, as the case may be, Subfacility) being prepaid and the Type(s)
of Loans to be prepaid. The Administrative Agent will promptly notify each
Lender of its receipt of each such notice, and of such Lender's Pro Rata Share
of such prepayment. If such notice is given by the Borrower, the Borrower shall
make such prepayment and the payment amount specified in such notice shall be
due and payable on the date specified therein. Any prepayment of a Eurodollar
Rate Loan shall be accompanied by all accrued interest thereon, together with
any additional amounts required pursuant to SECTION 3.05. Each such prepayment
shall be applied to the Loans of the Lenders in accordance with their respective
Pro Rata Shares.

         Unless a Default or Event of Default has occurred and is continuing or
would arise as a result thereof any payment or prepayment of the Revolver
Principal Debt may be reborrowed by Borrower, subject to the terms and
conditions hereof.

         (b) Mandatory Prepayments from Net Cash Proceeds. Until such time as
the Outstanding Amount has been repaid in full and the Revolver Commitment
terminated in full, the Outstanding Amount (and, as applicable, the Revolver
Commitment) shall be permanently prepaid (or reduced, as the case may be), in
the amounts and upon the occurrence of any of the following events:

                                       21
<PAGE>

                  (i) Debt Issuance. In the event of any Debt Issuance by a
         Company, if Outstanding Indebtedness exceeds $30,000,000 after giving
         effect to such Debt Issuance, then concurrently with such Debt
         Issuance, the Loans shall be prepaid using Net Cash Proceeds of such
         Debt Issuance (and the Revolver Commitment reduced to the extent
         required by this SECTION 2.04(b)) by the Required Amount as defined in
         this SECTION 2.04(b)(i). As used in this Section: (A) "Outstanding
         Indebtedness" as of any date means the aggregate principal amount of
         outstanding Indebtedness plus the Attributable Principal of all
         Synthetic Leases of the Borrower and its Subsidiaries (including the
         Indebtedness and Synthetic Leases being issued, incurred or assumed on
         such date but excluding Permitted Affiliate Subordinated Debt and
         excluding Indebtedness under the Loan Documents), and (B) "Required
         Amount" means the lesser of (i) 100% of the Net Cash Proceeds of such
         Debt Issuance and (ii) amount by which the Outstanding Indebtedness
         exceeds $30,000,000.

                  (ii) Significant Sales. If any portion of the Net Cash
         Proceeds realized by a Company from any Significant Sale (including any
         deferred purchase price therefor and any Net Cash Proceeds of any asset
         disposition which constitutes a Significant Sale) has not been
         reinvested in assets used in the Present and Related Businesses of a
         Company within ninety (90) days from the receipt by such Company of
         such Net Cash Proceeds (including receipt of any deferred payments for
         any such Significant Sale or portion thereof, if and when received),
         then on the day following the ninetieth day after receipt of such Net
         Cash Proceeds, the Outstanding Amount shall be prepaid (and the
         Revolver Commitment reduced to the extent required in this SECTION
         2.04(b)), in the order and manner specified in the following paragraph,
         by an amount equal to 100% of all such Net Cash Proceeds not so
         reinvested.

         The commitment reductions or prepayments provided for under SECTIONS
2.04(b)(i) and (ii) are in addition to the payments provided for in SECTION
6.13. The prepayments and commitment reductions under SECTIONS 2.04(b)(i) and
(ii) shall be applied as follows, unless a Default or Event of Default has
occurred and is continuing or would arise as a result thereof (whereupon the
provisions of SECTION 2.13(b) shall apply): (A) first, as a prepayment of the
Term Loan Principal Debt until paid in full, and (B) second, as a mandatory
permanent reduction of the Revolver Commitment and a mandatory prepayment of the
Revolver Principal Debt, provided, however, the allocation of commitment
reductions or prepayments between the Subfacilities shall be determined (i) if
no Default or Event of Default has occurred and is continuing, in the order and
manner that the Borrower specifies, or (ii) if the Borrower fails to so specify
or if a Default or Event of Default has occurred and is continuing, in the order
and manner that the Revolver Required Lenders deem appropriate. All mandatory
prepayments of the Term Loan Principal Debt shall be allocated Pro Rata to each
Term Loan Lender. All mandatory prepayments of the Revolver Facility shall be
allocated Pro Rata to each Revolver Lender. All mandatory prepayments of the
Revolver Facility made pursuant to this SECTION 2.04(b) shall permanently reduce
the Revolver Commitment.

         (c) Clean-Down Period. The Borrower shall make such repayments of the
Working Capital/Distribution Subfacility Principal Debt as are required by
SECTION 6.13.

         (d) Revolver Facility Mandatory Payments/Reductions. On any date of
determination (i) if the Acquisition Subfacility Principal Debt exceeds the
Acquisition Subfacility Commitment then in effect (including as a result of any
Revolver Commitment reduction pursuant to SECTION 2.04(b)), then the Borrower
shall make a mandatory prepayment of the Acquisition Subfacility Principal Debt
in at least the amount of such excess, and (ii) if the Working
Capital/Distribution Subfacility Principal Debt exceeds the Working
Capital/Distribution Subfacility Commitment then in effect (including as a
result of any Revolver Commitment reduction pursuant to SECTION 2.04(b)), then
the Borrower shall make a mandatory

                                       22
<PAGE>

prepayment of the Working Capital/Distribution Subfacility Principal Debt in at
least the amount of such excess. All mandatory prepayments under the Revolver
Facility or Revolver Commitment reductions hereunder shall be allocated among
the Revolver Lenders in accordance with their respective Pro Rata Share under
the Revolver Facility.

         (e) Mandatory Prepayments: Interest/Consequential Loss. All prepayments
under this SECTION 2.04 shall be made together with accrued interest to the date
of such prepayment on the principal amount prepaid and any amounts due under
SECTION 3.05.

         2.05 REDUCTION OR TERMINATION OF COMMITMENTS. The Borrower may, upon
notice to the Administrative Agent, terminate the Aggregate Commitments, or
(prior to the Initial Funding Date) permanently reduce the Term Loan Commitment,
or permanently reduce the Revolver Commitment to an amount not less than the
then existing Revolver Principal Debt; provided that (i) any such notice shall
be received by the Administrative Agent not later than 11:00 a.m., five Business
Days prior to the date of termination or reduction, and (ii) any such partial
reduction shall be in an aggregate amount of $5,000,000 or any whole multiple of
$1,000,000 in excess thereof. The Administrative Agent shall promptly notify the
Lenders of any such notice of reduction or termination. Once reduced in
accordance with this Section, the Commitments may not be increased. Any
reduction of the Revolver Commitment shall be applied to the Commitment of each
Revolver Lender according to its Pro Rata Share, and any reduction of the Term
Loan Commitment shall be applied to the Commitment of each Term Loan Lender
according to its Pro Rata Share. All commitment fees on the portion of the
Commitment so terminated which have accrued to the effective date of any
termination of Commitments shall be paid on the effective date of such
termination.

         2.06 REPAYMENT OF LOANS. The Borrower shall repay to the Revolver
Lenders on the Revolver Maturity Date the Revolver Principal Debt and the
Borrower shall repay to the Term Loan Lenders on the Term Loan Maturity Date the
Term Loan Principal Debt.

         2.07 INTEREST.

         (a) Subject to the provisions of subsection (b) below, (i) each
Eurodollar Rate Loan shall bear interest on the outstanding principal amount
thereof for each Interest Period at a rate per annum equal to the Eurodollar
Rate for such Interest Period plus the Applicable Rate and (ii) each Base Rate
Loan shall bear interest on the outstanding principal amount thereof from the
applicable borrowing date at a rate per annum equal to the Base Rate plus the
Applicable Rate.

         (b) While any Event of Default exists or after acceleration, (i) the
Borrower shall pay interest on the principal amount of all outstanding
Obligations at a fluctuating interest rate per annum at all times equal to the
Default Rate to the fullest extent permitted by applicable Law, and (ii) accrued
and unpaid interest on past due amounts (including interest on past due
interest) shall be due and payable upon demand.

         (c) Interest on each Loan shall be due and payable in arrears on each
Interest Payment Date applicable thereto and at such other times as may be
specified herein. Interest hereunder shall be due and payable in accordance with
the terms hereof before and after judgment, and before and after the
commencement of any proceeding under any Debtor Relief Law.

         (d) If the designated rate applicable to any Borrowing exceeds the
Maximum Rate, the rate of interest on such Borrowing shall be limited to the
Maximum Rate, but any subsequent reductions in such designated rate shall not
reduce the rate of interest thereon below the Maximum Rate until the total
amount

                                       23
<PAGE>

of interest accrued thereon equals the amount of interest which would have
accrued thereon if such designated rate had at all times been in effect. In the
event that at maturity (stated or by acceleration), or at final payment of the
Outstanding Amount, the total amount of interest paid or accrued is less than
the amount of interest which would have accrued if such designated rates had at
all times been in effect, then, at such time and to the extent permitted by Law,
the Borrower shall pay an amount equal to the difference between (a) the lesser
of the amount of interest which would have accrued if such designated rates had
at all times been in effect and the amount of interest which would have accrued
if the Maximum Rate had at all times been in effect, and (b) the amount of
interest actually paid or accrued on the Outstanding Amount.

         2.08 FEES.

         (a) Commitment Fee. For the period commencing on the Closing Date and
ending on the earlier of (i) the date of the initial Borrowing under the Term
Loan Facility or (ii) termination of the Term Loan Commitment, the Borrower
shall pay to the Administrative Agent for the account of each Term Loan Lender
in accordance with its Pro Rata Share, a commitment fee equal to the Applicable
Rate times the Term Loan Commitment. For the period commencing on the Closing
Date and ending on the Revolver Maturity Date, the Borrower shall pay to the
Administrative Agent for the account of each Revolver Lender in accordance with
its Pro Rata Share, a commitment fee equal to the Applicable Rate times the
actual daily amount by which the aggregate Revolver Commitment exceeds the
Revolver Principal Debt. The commitment fee shall accrue at all times from the
Closing Date, and shall be due and payable quarterly in arrears on the last
Business Day of each March, June, September and December, commencing with the
first such date to occur after the Closing Date, and on the Maturity Date. The
commitment fee shall be calculated quarterly in arrears, and if there is any
change in the Applicable Rate during any quarter, the actual daily amount shall
be computed and multiplied by the Applicable Rate separately for each period
during such quarter that such Applicable Rate was in effect. The commitment fee
shall accrue at all times, including at any time during which one or more of the
conditions in ARTICLE IV is not met.

         (b) Arrangement and Agency Fees. The Borrower shall pay an arrangement
fee to the Arrangers for the Arrangers' own account, and shall pay an agency fee
to the Administrative Agent for the Administrative Agent's own account, in the
amounts and at the times specified in the letter agreement, dated January 5,
2001 (the "AGENT/ARRANGER FEE LETTER"), between the Borrower, the Arrangers and
the Administrative Agent. Such fees shall be fully earned when paid and shall be
nonrefundable for any reason whatsoever.

         (c) Lenders' Upfront Fee. On the Initial Funding Date, the Borrower
shall pay to the Administrative Agent, for the account of the Lenders in
accordance with their respective Pro Rata Shares, an upfront fee in the agreed
amount in accordance with the Agent/Arranger Fee Letter. Such upfront fees are
for the credit facilities by the Lenders under this Agreement and are fully
earned on the date paid. The upfront fee paid to each Lender is solely for its
own account and is nonrefundable for any reason whatsoever.

         2.09 COMPUTATION OF INTEREST AND FEES. Computation of interest on Base
Rate Loans shall be calculated on the basis of a year of 365 or 366 days, as the
case may be, and the actual number of days elapsed. Computation of all other
types of interest and all fees shall be calculated on the basis of a year of 360
days and the actual number of days elapsed, which results in a higher yield to
the payee thereof than a method based on a year of 365 or 366 days. Interest
shall accrue on each Loan for the day on which the Loan is made, and shall not
accrue on a Loan, or any portion thereof, for the day on which the Loan or such
portion is paid, provided that any Loan that is repaid on the same day on which
it is made shall bear interest for one day.

                                       24
<PAGE>

         2.10 EVIDENCE OF DEBT. The Loans made by each Lender shall be evidenced
by one or more accounts or records maintained by such Lender and by the
Administrative Agent in the ordinary course of business. The accounts or records
maintained by the Administrative Agent and each Lender shall be conclusive
absent manifest error of the amount of the Loans made by the Lenders to the
Borrower and the interest and payments thereon. Any failure so to record or any
error in doing so shall not, however, limit or otherwise affect the obligation
of the Borrower hereunder to pay any amount owing with respect to the Loans. In
the event of any conflict between the accounts and records maintained by any
Lender and the accounts and records of the Administrative Agent in respect of
such matters, the accounts and records of such Lender shall control. Upon the
request of any Lender made through the Administrative Agent, such Lender's Loans
may be evidenced by one or more of the following Notes (as the case may be): (i)
a Revolver Note (with respect to the Revolver Principal Debt), and (ii) a Term
Note (with respect to the Term Loan Principal Debt). Each Lender may attach
schedules to its Note(s) and endorse thereon the date, Type (if applicable),
amount and maturity of the applicable Loans and payments with respect thereto.

         2.11 PAYMENTS GENERALLY.

         (a) All payments to be made by the Borrower shall be made without
condition or deduction for any counterclaim, defense, recoupment or setoff.
Except as otherwise expressly provided herein, all payments by the Borrower
hereunder shall be made to the Administrative Agent, for the account of the
respective Lenders to which such payment is owed, at the Administrative Agent's
Office in Dollars and in immediately available funds not later than 12:00 noon,
New York time, on the date specified herein. The Administrative Agent will
promptly distribute to each Lender its Pro Rata Share (or other applicable share
as provided herein) of such payment in like funds as received by wire transfer
to such Lender's Lending Office. All payments received by the Administrative
Agent after 12:00 noon, New York time, shall be deemed received on the next
succeeding Business Day and any applicable interest or fee shall continue to
accrue.

         (b) Subject to the definition of "Interest Period," if any payment to
be made by the Borrower shall come due on a day other than a Business Day,
payment shall be made on the next following Business Day, and such extension of
time shall be reflected in computing interest or fees, as the case may be.

         (c) If at any time insufficient funds are received by and available to
the Administrative Agent to pay fully the Obligations, such funds shall be
applied (i) first, toward costs and expenses (including Attorney Costs and
amounts payable under ARTICLE III) incurred by the Administrative Agent and each
Lender, (ii) second, toward repayment of interest and fees then due hereunder,
ratably among the parties entitled thereto in accordance with the amounts of
interest and fees then due to such parties, (iii) third, toward repayment of
principal then due hereunder, ratably among the parties entitled thereto in
accordance with the amounts of principal then due to such parties, and (iv)
fourth, toward the repayment of all other Obligations.

         (d) Unless the Borrower or any Lender has notified the Administrative
Agent prior to the date any payment is required to be made by it to the
Administrative Agent hereunder, that the Borrower or such Lender, as the case
may be, will not make such payment, the Administrative Agent may assume that the
Borrower or such Lender, as the case may be, has timely made such payment and
may (but shall not be so required to), in reliance thereon, make available a
corresponding amount to the Person entitled thereto. If and to the extent that
such payment was not in fact made to the Administrative Agent in immediately
available funds, then:

                                       25
<PAGE>

                  (i) if the Borrower failed to make such payment, each Lender
         shall forthwith on demand repay to the Administrative Agent the portion
         of such assumed payment that was made available to such Lender in
         immediately available funds, together with interest thereon in respect
         of each day from and including the date such amount was made available
         by the Administrative Agent to such Lender to the date such amount is
         repaid to the Administrative Agent in immediately available funds, at
         the Federal Funds Rate from time to time in effect; and

                  (ii) if any Lender failed to make such payment, such Lender
         shall forthwith on demand pay to the Administrative Agent the amount
         thereof in immediately available funds, together with interest thereon
         for the period from the date such amount was made available by the
         Administrative Agent to the Borrower to the date such amount is
         recovered by the Administrative Agent (the "COMPENSATION PERIOD") at a
         rate per annum equal to the Federal Funds Rate from time to time in
         effect. If such Lender pays such amount to the Administrative Agent,
         then such amount shall constitute such Lender's Loan, included in the
         applicable Borrowing. If such Lender does not pay such amount forthwith
         upon the Administrative Agent's demand therefor, the Administrative
         Agent may make a demand therefor upon the Borrower, and the Borrower
         shall pay such amount to the Administrative Agent, together with
         interest thereon for the Compensation Period at a rate per annum equal
         to the rate of interest applicable to the applicable Borrowing. Nothing
         herein shall be deemed to relieve any Lender from its obligation to
         fulfill its Commitment or to prejudice any rights which the
         Administrative Agent or the Borrower may have against any Lender as a
         result of any default by such Lender hereunder.

         A notice of the Administrative Agent to any Lender with respect to any
amount owing under this subsection (d) shall be conclusive, absent manifest
error.

         (e) If any Lender makes available to the Administrative Agent funds for
any Loan to be made by such Lender as provided in the foregoing provisions of
this ARTICLE II, and the conditions to the applicable Borrowing set forth in
ARTICLE IV are not satisfied or waived in accordance with the terms hereof, the
Administrative Agent shall return such funds (in like funds as received from
such Lender) to such Lender, without interest.

         (f) The obligations of the Lenders hereunder to make Loans are several
and not joint. The failure of any Lender to make any Loan on any date required
hereunder shall not relieve any other Lender of its corresponding obligation to
do so on such date, and no Lender shall be responsible for the failure of any
other Lender to so make its Loan or purchase its participation.

         (g) Nothing herein shall be deemed to obligate any Lender to obtain the
funds for any Loan in any particular place or manner or to constitute a
representation by any Lender that it has obtained or will obtain the funds for
any Loan in any particular place or manner.

         2.12 SHARING OF PAYMENTS. If, other than as expressly provided
elsewhere herein, any Lender shall obtain on account of the Loans made by it,
any payment (whether voluntary, involuntary, through the exercise of any right
of set-off, or otherwise) in excess of its ratable share (or other share
contemplated hereunder) thereof, such Lender shall immediately (a) notify the
Administrative Agent of such fact, and (b) purchase from the other Lenders such
participations in the Loans made by them, as shall be necessary to cause such
purchasing Lender to share the excess payment in respect of such Loan or such
participations, as the case may be, pro rata with each of them; provided,
however, that if all or any portion of such excess payment is thereafter
recovered from the purchasing Lender, such purchase shall to that extent be
rescinded and each other Lender shall repay to the purchasing Lender the
purchase price paid therefor, together with

                                       26
<PAGE>

an amount equal to such paying Lender's ratable share (according to the
proportion of (i) the amount of such paying 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 of the total
amount so recovered. The Borrower agrees that any Lender so purchasing a
participation from another Lender may, to the fullest extent permitted by law,
exercise all its rights of payment (including the right of set-off, but subject
to SECTION 10.09) with respect to such participation as fully as if such Lender
were the direct creditor of the Borrower in the amount of such participation.
The Administrative Agent will keep records (which shall be conclusive and
binding in the absence of manifest error) of participations purchased under this
Section and will in each case notify the Lenders following any such purchases or
repayments. Each Lender that purchases a participation pursuant to this Section
shall from and after such purchase have the right to give all notices, requests,
demands, directions and other communications under this Agreement with respect
to the portion of the Obligations purchased to the same extent as though the
purchasing Lender were the original owner of the Obligations purchased.

         2.13 ORDER OF APPLICATION.

         (a) No Default. If no Default or Event of Default exists and if no
order of application is otherwise specified in the Loan Documents, payments and
prepayments of the Obligations shall be applied first to fees, second to accrued
interest then due and payable on the Outstanding Amount, and then to the
remaining Obligations in the order and manner as Borrower may direct.

         (b) Default. If a Default or Event of Default exists (or if Borrower
fails to give directions as permitted under SECTION 2.13(a)), any payment or
prepayment (including proceeds from the exercise of any Rights) shall be applied
to the Obligations in the following order: (i) to the payment of enforcement
expenses incurred by the Administrative Agent, including Attorney Costs; (ii) to
the ratable payment of all other fees, expenses, and indemnities for which the
Administrative Agent or Lenders have not been paid or reimbursed in accordance
with the Loan Documents (as used in this SECTION 2.13(b)(ii), a "RATABLE
PAYMENT" for any Lender or the Administrative Agent shall be, on any date of
determination, that proportion which the portion of the total fees, expenses,
and indemnities owed to such Lender or the Administrative Agent bears to the
total aggregate fees and indemnities owed to all Lenders and the Administrative
Agent on such date of determination); (iii) to the ratable payment of accrued
and unpaid interest on the Outstanding Amount (as used in this SECTION
2.13(b)(iii), "RATABLE PAYMENT" means, for any Lender, on any date of
determination, that proportion which the accrued and unpaid interest on the
Outstanding Amount owed to such Lender bears to the total accrued and unpaid
interest on the Outstanding Amount owed to all Lenders); (iv) to the ratable
payment of the Outstanding Amount (as used in this SECTION 2.13(b)(iv), "RATABLE
PAYMENT" means for any Lender, on any date of determination, that proportion
which the Outstanding Amount owed to such Lender bears to the Outstanding Amount
owed to all Lenders); and (v) to the payment of the remaining Obligations, if
any, in the order and manner Required Lenders deem appropriate.

         Subject to the provisions of ARTICLE IX and provided that
Administrative Agent shall not in any event be bound to inquire into or to
determine the validity, scope, or priority of any interest or entitlement of any
Lender and may suspend all payments or seek appropriate relief (including,
without limitation, instructions from Required Lenders or an action in the
nature of interpleader) in the event of any doubt or dispute as to any
apportionment or distribution contemplated hereby, Administrative Agent shall
promptly distribute such amounts to each Lender in accordance with the Agreement
and the related Loan Documents.

                                  ARTICLE III.
                     TAXES, YIELD PROTECTION AND ILLEGALITY

         3.01 TAXES.

         (a) Any and all payments by the Borrower to or for the account of the
Administrative Agent or any Lender under any Loan Document shall be made free
and clear of and without deduction for any and all present or future taxes,
duties, levies, imposts, deductions, assessments, fees, withholdings or similar
charges, and all liabilities with respect thereto, excluding, in the case of the
Administrative Agent and each Lender, taxes imposed on or measured by its net
income, and franchise taxes imposed on it (in lieu of net income taxes), by the
jurisdiction (or any political subdivision thereof) under the Laws of which the
Administrative Agent or such Lender, as the case may be, is organized or
maintains its Lending Office (all such non-excluded taxes, duties, levies,
imposts, deductions, assessments, fees, withholdings or similar charges, and
liabilities being hereinafter referred to as "TAXES"). If the Borrower shall be
required by any Laws to deduct any Taxes from or in respect of any sum payable
under any Loan Document to the Administrative Agent or any Lender, (i) the sum
payable shall be increased as necessary so that after making all required
deductions (including deductions applicable to additional sums payable under
this Section), each of the Administrative Agent and such Lender receives an
amount equal to the sum it would have received had no such deductions been made,
(ii) the Borrower shall make such deductions, (iii) the Borrower shall pay the
full amount deducted to the relevant taxation authority or other authority in
accordance with applicable Laws, and (iv) within 30 days after the date of such
payment, the Borrower shall furnish to the Administrative Agent (which shall
forward the same to such Lender) the original or a certified copy of a receipt
evidencing payment thereof.

         (b) In addition, the Borrower agrees to pay any and all present or
future stamp, court or documentary taxes and any other excise or property taxes
or charges or similar levies which arise from any payment made under any Loan
Document or from the execution, delivery, performance, enforcement or
registration of, or otherwise with respect to, any Loan Document (hereinafter
referred to as "OTHER TAXES").

         (c) If the Borrower shall be required to deduct or pay any Taxes or
Other Taxes from or in respect of any sum payable under any Loan Document to the
Administrative Agent or any Lender, the Borrower shall also pay to the
Administrative Agent (for the account of such Lender) or to such Lender, at the
time interest is paid, such additional amount that such Lender specifies as
necessary to preserve the after-tax yield (after factoring in all taxes,
including taxes imposed on or measured by net income) such Lender would have
received if such Taxes or Other Taxes had not been imposed.

         (d) The Borrower agrees to indemnify the Administrative Agent and each
Lender for (i) the full amount of Taxes and Other Taxes (including any Taxes or
Other Taxes imposed or asserted by any jurisdiction on amounts payable under
this Section) paid by the Administrative Agent and such Lender, (ii) amounts
payable under SECTION 3.01(c) and (iii) any liability (including penalties,
interest and expenses) arising therefrom or with respect thereto. Payment under
this subsection (d) shall be made within 30 days after the date the Lender or
the Administrative Agent makes a demand therefor.

         3.02 ILLEGALITY. If any Lender determines that any Law has made it
unlawful, or that any Governmental Authority has asserted that it is unlawful,
for any Lender or its applicable Lending Office to make, maintain or fund
Eurodollar Rate Loans, or materially restricts the authority of such Lender to
purchase or sell, or to take deposits of, Dollars in the applicable offshore
Dollar market, or to determine or charge interest rates based upon the
Eurodollar Rate, then, on notice thereof by such Lender to the

                                       28
<PAGE>

Borrower through the Administrative Agent, any obligation of such Lender to make
or continue Eurodollar Rate Loans or to convert Base Rate Loans to Eurodollar
Rate Loans shall be suspended until such Lender notifies the Administrative
Agent and the Borrower that the circumstances giving rise to such determination
no longer exist. Upon receipt of such notice, the Borrower shall, upon demand
from such Lender (with a copy to the Administrative Agent), prepay or, if
applicable, convert all Eurodollar Rate Loans of such Lender to Base Rate Loans,
either on the last day of the Interest Period thereof, if such Lender may
lawfully continue to maintain such Eurodollar Rate Loans to such day, or
immediately, if such Lender may not lawfully continue to maintain such
Eurodollar Rate Loans. Upon any such prepayment or conversion, the Borrower
shall also pay interest on the amount so prepaid or converted. Each Lender
agrees to designate a different Lending Office if such designation will avoid
the need for such notice and will not, in the reasonable judgment of such
Lender, otherwise be materially disadvantageous to such Lender.

         3.03 INABILITY TO DETERMINE RATES. If the Administrative Agent
determines in connection with any request for a Eurodollar Rate Loan or a
conversion to or continuation thereof that (a) Dollar deposits are not being
offered to banks in the applicable offshore Dollar market for the applicable
amount and Interest Period of such Eurodollar Rate Loan, or adequate and
reasonable means do not exist for determining the Eurodollar Rate for such
Eurodollar Rate Loan, or (b) if the Required Lenders determine and notify the
Administrative Agent that the Eurodollar Rate for such Eurodollar Rate Loan does
not adequately and fairly reflect the cost to the Lenders of funding such
Eurodollar Rate Loan, then the Administrative Agent will promptly notify the
Borrower and all Lenders. Thereafter, the obligation of the Lenders to make or
maintain Eurodollar Rate Loans shall be suspended until the Administrative Agent
revokes such notice. Upon receipt of such notice, the Borrower may revoke any
pending request for a Borrowing, conversion or continuation of Eurodollar Rate
Loans or, failing that, will be deemed to have converted such request into a
request for a Borrowing of Base Rate Loans in the amount specified therein.

         3.04 INCREASED COST AND REDUCED RETURN; CAPITAL ADEQUACY; RESERVES ON
EURODOLLAR RATE LOANS.

         (a) If any Lender determines that as a result of the introduction of or
any change in or in the interpretation of any Law, or such Lender's compliance
therewith, there shall be any increase in the cost to such Lender of agreeing to
make or making, funding or maintaining Eurodollar Rate Loans, or a reduction in
the amount received or receivable by such Lender in connection with any of the
foregoing (excluding for purposes of this subsection (a) any such increased
costs or reduction in amount resulting from (i) Taxes or Other Taxes (as to
which SECTION 3.01 shall govern), (ii) changes in the basis of taxation of
overall net income or overall gross income by the United States or any foreign
jurisdiction or any political subdivision of either thereof under the Laws of
which such Lender is organized or has its Lending Office, and (iii) reserve
requirements contemplated by SECTION 3.04(c) utilized, as to Eurodollar Rate
Loans, in the determination of the Eurodollar Rate), then from time to time upon
demand of such Lender (with a copy of such demand to the Administrative Agent),
the Borrower shall pay to such Lender such additional amounts as will compensate
such Lender for such increased cost or reduction. No Lender shall have the right
to recover such additional amounts for any period more than 90 days prior to the
date such Lender notified the Borrower thereof.

         (b) If any Lender determines that the introduction of any Law regarding
capital adequacy or any change therein or in the interpretation thereof, or
compliance by such Lender (or its Lending Office) therewith, 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 such Lender's obligations hereunder
(taking into consideration its policies with respect to capital adequacy and
such Lender's desired return on capital), then from time to time upon demand of
such Lender (with a copy of such demand to the Administrative Agent), the
Borrower

                                       29
<PAGE>

shall pay to such Lender such additional amounts as will compensate such Lender
for such reduction. No Lender shall have the right to recover such additional
amounts for any period more than 90 days prior to the date such Lender notified
the Borrower thereof.

         (c) The Borrower shall pay to each Lender, as long as such Lender shall
be required under regulations of the Board to maintain reserves with respect to
liabilities or assets consisting of or including Eurocurrency funds or deposits
(currently known as "Eurocurrency liabilities"), additional costs on the unpaid
principal amount of each Eurodollar Rate Loan equal to the actual costs of such
reserves allocated to such Loan by such Lender (as determined by such Lender in
good faith, which determination shall be conclusive), which shall be due and
payable on each date on which interest is payable on such Loan, provided the
Borrower shall have received at least 15 days' prior notice (with a copy to the
Administrative Agent) of such additional interest from such Lender. If a Lender
fails to give notice 15 days prior to the relevant Interest Payment Date, such
additional interest shall be due and payable 15 days from receipt of such
notice.

         3.05 FUNDING LOSSES. Upon demand of any Lender (with a copy to the
Administrative Agent) from time to time, the Borrower shall promptly compensate
such Lender for and hold such Lender harmless from any loss, cost or expense
incurred by it as a result of:

         (a) any continuation, conversion, payment or prepayment of any Loan
other than a Base Rate Loan on a day other than the last day of the Interest
Period for such Loan (whether voluntary, mandatory, automatic, by reason of
acceleration, or otherwise); or

         (b) any failure by the Borrower (for a reason other than the failure of
such Lender to make a Loan) to prepay, borrow, continue or convert any Loan
other than a Base Rate Loan on the date or in the amount notified by the
Borrower.

For purposes of calculating amounts payable by the Borrower to the Lenders under
this SECTION 3.05, each Lender shall be deemed to have funded each Eurodollar
Rate Loan made by it at the Eurodollar Rate for such Loan by a matching deposit
or other borrowing in the applicable offshore Dollar interbank market for a
comparable amount and for a comparable period, whether or not such Eurodollar
Rate Loan was in fact so funded.

         3.06 MATTERS APPLICABLE TO ALL REQUESTS FOR COMPENSATION. A certificate
of the Administrative Agent or any Lender claiming compensation under this
ARTICLE III and setting forth the additional amount or amounts to be paid to it
hereunder shall be conclusive in the absence of manifest error. In determining
such amount, the Administrative Agent or such Lender may use any reasonable
averaging and attribution methods.

         3.07 SURVIVAL. All of the Borrower's obligations under this ARTICLE III
shall survive termination of the Commitments and payment in full of all the
other Obligations.

                                  ARTICLE IV.
                       CONDITIONS PRECEDENT TO BORROWINGS

         4.01 CONDITIONS OF INITIAL BORROWING. The obligation of each Lender to

                                   ARTICLE V.
                         REPRESENTATIONS AND WARRANTIES

         The Borrower represents and warrants to the Administrative Agent and
the Lenders that:

         5.01 EXISTENCE; QUALIFICATION AND POWER; COMPLIANCE WITH LAWS. As of
the Initial Funding Date, the General Partner shall be the sole general partner
of the Borrower, and all of the limited partnership interests in the Borrower
shall be owned by the MLP. The General Partner and each Loan Party (a) is a
corporation, partnership or limited liability company duly organized or formed,
validly existing and in good standing under the Laws of the jurisdiction of its
incorporation or organization, (b) has all requisite power and authority and all
governmental licenses, authorizations, consents and approvals to own its assets,
carry on its business and to execute, deliver, and perform its obligations under
the Loan Documents to which it is a party, (c) is duly qualified and is licensed
and in good standing under the Laws of each jurisdiction where its ownership,
lease or operation of properties or the conduct of its business requires such
qualification or license, and (d) is in compliance with all Laws, except in each
case referred to in clause (c) or this clause (d), to the extent that failure to
do so could not reasonably be expected to have a Material Adverse Effect.

         5.02 AUTHORIZATION; NO CONTRAVENTION. The execution, delivery and
performance by each Loan Party of each Loan Document to which such Person is
party, have been duly authorized by all necessary corporate or other
organizational action, and do not and will not (a) contravene the terms of any
of such Person's Organization Documents; (b) conflict with or result in any
breach or contravention of, or the creation of any Lien under, any Contractual
Obligation to which such Person is a party or any order, injunction, writ or
decree of any Governmental Authority to which such Person or its property is
subject; or (c) violate any Law.

         5.03 GOVERNMENTAL AUTHORIZATION. No approval, consent, exemption,
authorization, or other action by, or notice to, or filing with, any
Governmental Authority is necessary or required in connection with the
execution, delivery or performance by, or enforcement against, any Loan Party of
this Agreement or any other Loan Document.

         5.04 BINDING EFFECT. This Agreement has been, and each other Loan
Document, when delivered hereunder, will have been duly executed and delivered
by each Loan Party that is party thereto. This Agreement constitutes, and each
other Loan Document when so delivered will constitute, a legal, valid and
binding obligation of such Loan Party, enforceable against each Loan Party that
is party thereto in accordance with its terms.

         5.05 FINANCIAL STATEMENTS; NO MATERIAL ADVERSE EFFECT.

         (a) The Initial Funding Date Financial Statements were prepared in
accordance with GAAP consistently applied throughout the period covered thereby,
except as otherwise expressly noted therein. The Initial Funding Date Pro Formas
and the Initial Funding Date Financial Statements (i) fairly present the
financial condition of the entities therein named and their respective
Subsidiaries as of the date thereof and their results of operations for the
period covered thereby in accordance with GAAP consistently applied throughout
the period covered thereby, except as otherwise expressly noted therein; and
(ii) show all

                                       33
<PAGE>

material indebtedness and other liabilities, direct or contingent, of the
entities therein named and their Subsidiaries as of the date thereof, including
liabilities for taxes, material commitments and Indebtedness in accordance with
GAAP consistently applied throughout the period covered thereby.

         (b) Since the dates of the Initial Funding Date Financial Statements,
there has been no event or circumstance that has or could reasonably be expected
to have a Material Adverse Effect.

         5.06 LITIGATION. There are no actions, suits, proceedings, claims or
disputes pending or, to the knowledge of the Borrower after due and diligent
investigation, overtly threatened or contemplated, at law, in equity, in
arbitration or before any Governmental Authority, by or against the Borrower or
any of its Subsidiaries or against any of their properties or revenues which (a)
purport to affect or pertain to this Agreement or any other Loan Document, or
any of the transactions contemplated hereby, or (b) if determined adversely,
could reasonably be expected to have a Material Adverse Effect.

         5.07 NO DEFAULT. There is no failure of any Material Agreement to be in
effect, and there is no default by the Borrower or any of its Subsidiaries under
any Material Agreement, if such failure to remain in effect, or such default,
could reasonably be expected to have a Material Adverse Effect.

         5.08 OWNERSHIP OF PROPERTY; LIENS. The Borrower and each Subsidiary has
good and marketable title to, or valid leasehold interests in, all its real and
personal property necessary or used in the ordinary conduct of its business,
except for such defects in title as would not, individually or in the aggregate,
have a Material Adverse Effect. As of the Conditions Effective Date, the
property of the Borrower and its Subsidiaries is subject to no Liens, other than
Permitted Liens.

         5.09 ENVIRONMENTAL COMPLIANCE. The Borrower has reasonably concluded
that (a) there are no claims alleging potential liability under or
responsibility for violation of any Environmental Law except any such claims
that would not, individually or in the aggregate, have a Material Adverse
Effect, (b) there is no environmental condition or circumstance, such as the

Borrower and its Subsidiaries are insured with financially sound and reputable

         5.12 ERISA COMPLIANCE.

         (a) Each Plan is in compliance in all material respects with the
applicable provisions of ERISA, the Code and other Federal or state Laws except
to the extent that noncompliance could not reasonably be expected to have a
Material Adverse Effect. Each Plan that is intended to qualify under Section
401(a) of the Code has received a favorable determination letter from the IRS or
an application for such a letter is currently being processed by the IRS with
respect thereto and, to the best knowledge of the Borrower, nothing has occurred
which would prevent, or cause the loss of, such qualification. The Borrower and
each ERISA Affiliate have made all required contributions to each Plan subject
to Section 412 of the Code, and no application for a funding waiver or an
extension of any amortization period pursuant to Section 412 of the Code has
been made with respect to any Plan.

         (b) There are no pending or, to the best knowledge of the Borrower,
threatened claims, actions or lawsuits, or action by any Governmental Authority,
with respect to any Plan that could be reasonably be expected to have a Material
Adverse Effect. Neither the Borrower nor any ERISA Affiliate has engaged in or
knowingly permitted to occur and, to the Borrower's knowledge, no other party
has engaged in or permitted to occur any prohibited transaction or violation of
the fiduciary responsibility rules with respect to any Plan that has resulted or
could be reasonably expected to result in a Material Adverse Effect.

         (c) (i) No ERISA Event has occurred or is reasonably expected to occur;
(ii) no Pension Plan has any Unfunded Pension Liability that (when aggregated
with any other Unfunded Pension Liability) has resulted or could reasonably be
expected to result in a Material Adverse Effect; (iii) neither the Borrower nor
any ERISA Affiliate has incurred, or reasonably expects to incur, any liability
under Title IV of ERISA with respect to any Pension Plan (other than premiums
due and not delinquent under Section 4007 of ERISA) which could reasonably be
expected to result in a Material Adverse Effect; (iv) neither the Borrower nor
any ERISA Affiliate has incurred, or reasonably expects to incur, any liability
(and no event has occurred which, with the giving of notice under Section 4219
of ERISA, would result in such liability) under Sections 4201 or 4243 of ERISA
with respect to a Multiemployer Plan which could reasonably be expected to
result in a Material Adverse Effect; and (v) neither the Borrower nor any ERISA
Affiliate has engaged in a transaction that could be subject to Sections 4069 or
4212(c) of ERISA.

         5.13 SUBSIDIARIES. As of the Closing Date the Borrower has no
Subsidiaries. As of the Initial Funding Date the Borrower will have no
Subsidiaries other than those specifically disclosed in SCHEDULE 5.13.

         5.14 MARGIN REGULATIONS; INVESTMENT COMPANY ACT; PUBLIC UTILITY HOLDING
COMPANY ACT; USE OF PROCEEDS.

         (a) The Borrower is not engaged and will not engage, principally or as
one of its important activities, in the business of purchasing or carrying
margin stock (within the meaning of Regulation U issued by the Board), or
extending credit for the purpose of purchasing or carrying margin stock. Margin
Stock constitutes less than 25% of those assets of the Loan Parties which are
subject to any limitation on a sale, pledge, or other restrictions hereunder.

         (b) None of the Borrower, any Person controlling the Borrower, or any
Subsidiary (i) is a "holding company," or a "subsidiary company" of a "holding
company," or an "affiliate" of a "holding company" or of a "subsidiary company"
of a "holding company," within the meaning of the Public Utility Holding Company
Act of 1935, or (ii) is or is required to be registered as an "investment
company" under the Investment Company Act of 1940.

                                       35
<PAGE>

         (c) The Borrower will use all proceeds of Borrowings in the manner set
forth in SECTION 6.12.

         5.15 DISCLOSURE. No statement, information, report, representation, or
warranty made by any Loan Party in any Loan Document or furnished to the
Administrative Agent or any Lender by or on behalf of any Loan Party in
connection with any Loan Document contains any untrue statement of a material
fact or omits any material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading.

         5.16 LABOR MATTERS. To the Borrower's knowledge, there are no actual or
threatened strikes, labor disputes, slowdowns, walkouts, or other concerted
interruptions of operations by the employees of the Borrower or any of its
Subsidiaries that could reasonably be expected to have a Material Adverse
Effect. Hours worked by and payment made to employees of the Borrower or any of
its Subsidiaries have not been in violation of the Fair Labor Standards Act of
1938 or any other applicable Law dealing with such matters, other than any such
violations, individually or collectively, which could not reasonably be expected
to have a Material Adverse Effect. All payments due from the Borrower or any of
its Subsidiaries on account of employee health and welfare insurance have been
paid or accrued as a liability on its books, other than any such nonpayments
which could not, individually or collectively, reasonably be expected to have a
Material Adverse Effect.

         5.17 COMPLIANCE WITH LAWS. Neither the Borrower nor any of its
Subsidiaries are in violation of any Laws, other than such violations which
could not, individually or collectively, reasonably be expected to have a
Material Adverse Effect. Neither the Borrower nor any of its Subsidiaries has
received notice alleging any noncompliance with any Laws, except for such
noncompliance which no longer exists, or which non-compliance could not
reasonably be expected to have a Material Adverse Effect.

                                  ARTICLE VI.

make any payments of principal or interest on Permitted Affiliate Subordinated

         ACQUISITION") occurring during the period commencing on the first day
         of such period to and including the date of determination (herein
         called the "REFERENCE PERIOD"), as if such Asset Acquisition occurred
         on the first day of the Reference Period (an Asset Acquisition includes
         an asset acquisition that gives rise to the need to calculate
         compliance hereunder as a result of a Company incurring or assuming
         Indebtedness in connection with such asset acquisition); and

                  (ii) If, in connection with an Asset Acquisition during any
         Reference Period, any Indebtedness (including Permitted Affiliate

the application or consent of such Person and the appointment continues
undischarged or unstayed for 60 calendar days; or any proceeding under any
Debtor Relief Law relating to any such Person or to all or any part of its
property is instituted without the consent of such Person and continues

Multiemployer Plan which has resulted or could reasonably be expected to result
in liability of the Borrower or any Subsidiary under Title IV of ERISA to the
Pension Plan, Multiemployer Plan or the PBGC in an aggregate amount in excess of

whereupon such commitments and obligation shall be terminated;

         (b) shall, at the request of, or may, with the consent of, the Required

                                  ARTICLE IX.
                              ADMINISTRATIVE AGENT

         9.01 APPOINTMENT AND AUTHORIZATION OF ADMINISTRATIVE AGENT. Each Lender
hereby irrevocably (subject to SECTION 9.09) appoints, designates and authorizes
the Administrative Agent to take such action on its behalf under the provisions
of this Agreement and each other Loan Document and to exercise such powers and
perform such duties as are expressly delegated to it by the terms of this
Agreement or any other Loan Document, together with such powers as are
reasonably incidental thereto. Notwithstanding any provision to the contrary
contained elsewhere herein or in any other Loan Document, the Administrative
Agent shall not have any duties or responsibilities, except those expressly set
forth herein, nor shall the Administrative Agent have or be deemed to have any
fiduciary relationship with any Lender or participant, and no implied covenants,
functions, responsibilities, duties, obligations or liabilities shall be read
into this Agreement or any other Loan Document or otherwise exist against the
Administrative Agent. Without limiting the generality of the foregoing sentence,
the use of the term "agent" herein and in the other Loan Documents with
reference to the Administrative Agent is not intended to connote any fiduciary
or other implied (or express) obligations arising under agency doctrine of any
applicable law. Instead, such term is used merely as a matter of market custom,
and is intended to create or reflect only an administrative relationship between
independent contracting parties.

         9.02 DELEGATION OF DUTIES. The Administrative Agent may execute any of
its duties under this Agreement or any other Loan Document by or through agents,
employees or attorneys-in-fact and shall be entitled to advice of counsel and
other consultants or experts concerning all matters pertaining to such duties.
The Administrative Agent shall not be responsible for the negligence or
misconduct of any agent or attorney-in-fact that it selects in the absence of
gross negligence or willful misconduct.

         9.03 LIABILITY OF ADMINISTRATIVE AGENT. No Agent-Related Person shall
(a) be liable for any action taken or omitted to be taken by any of them under
or in connection with this Agreement or any other Loan Document or the
transactions contemplated hereby (except for its own gross negligence or willful
misconduct in connection with its duties expressly set forth herein), or (b) be
responsible in any manner to any Lender or participant for any recital,
statement, representation or warranty made by any Loan Party or any officer
thereof, contained herein or in any other Loan Document, or in any certificate,
report, statement or other document referred to or provided for in, or received
by the Administrative Agent under or in connection with, this Agreement or any
other Loan Document, or the validity, effectiveness, genuineness, enforceability
or sufficiency of this Agreement or any other Loan Document, or for any failure
of any Loan Party or any other party to any Loan Document to perform its
obligations hereunder or thereunder. No Agent-Related Person shall be under any
obligation to any Lender or participant to ascertain or to inquire as to the
observance or performance of any of the agreements contained in, or conditions
of, this Agreement or any other Loan Document, or to inspect the properties,
books or records of any Loan Party or any Affiliate thereof.

         9.04 RELIANCE BY ADMINISTRATIVE AGENT.

         (a) The Administrative Agent shall be entitled to rely, and shall be
fully protected in relying, upon any writing, communication, signature,
resolution, representation, notice, consent, certificate, affidavit, letter,
telegram, facsimile, telex or telephone message, statement or other document or
conversation believed by it to be genuine and correct and to have been signed,
sent or made by the proper

                                       47
<PAGE>

Person or Persons, and upon advice and statements of legal counsel (including
counsel to any Loan Party), independent accountants and other experts selected
by the Administrative Agent. The Administrative Agent shall be fully justified
in failing or refusing to take any action under any Loan Document unless it
shall first receive such advice or concurrence of the Required Lenders as it
deems appropriate and, if it so requests, 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. The
Administrative Agent shall in all cases be fully protected in acting, or in
refraining from acting, under this Agreement or any other Loan Document in
accordance with a request or consent of the Required Lenders or all the Lenders,
if required hereunder, and such request and any action taken or failure to act
pursuant thereto shall be binding upon all the Lenders and participants. Where
this Agreement expressly permits or prohibits an action unless the Required
Lenders otherwise determine, the Administrative Agent shall, and in all other
instances, the Administrative Agent may, but shall not be required to, initiate
any solicitation for the consent or a vote of the Lenders.

         (b) For purposes of determining compliance with the conditions to the
initial Borrowing specified in SECTION 4.01, each Lender that has funded its Pro
Rata Share of the Borrowing(s) on the Initial Funding Date shall be deemed to
have consented to, approved or accepted or to be satisfied with, each document
or other matter either sent by the Administrative Agent to such Lender for
consent, approval, acceptance or satisfaction, or required hereunder to be
consented to or approved by or acceptable or satisfactory to a Lender.

         9.05 NOTICE OF DEFAULT. The Administrative Agent shall not be deemed to
have knowledge or notice of the occurrence of any Default or Event of Default,
except with respect to defaults in the payment of principal, interest and fees
required to be paid to the Administrative Agent for the account of the Lenders,
unless the Administrative Agent shall have received written 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." The
Administrative Agent will notify the Lenders of its receipt of any such notice.
The Administrative Agent shall take such action with respect to such Default or
Event of Default as may be directed by the Required Lenders in accordance with
ARTICLE VIII; provided, however, that unless and until the Administrative Agent
has received any such direction, 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 or in the best
interest of the Lenders.

         9.06 CREDIT DECISION; DISCLOSURE OF INFORMATION BY ADMINISTRATIVE
AGENT. Each Lender acknowledges that no Agent-Related Person has made any
representation or warranty to it, and that no act by the Administrative Agent
hereinafter taken, including any consent to and acceptance of any assignment or
review of the affairs of any Loan Party or any Affiliate thereof, shall be
deemed to constitute any representation or warranty by any Agent-Related Person
to any Lender as to any matter, including whether Agent-Related Persons have
disclosed material information in their possession. Each Lender represents to
the Administrative Agent that it has, independently and without reliance upon
any Agent-Related Person and based on such documents and information as it has
deemed appropriate, made its own appraisal of and investigation into the
business, prospects, operations, property, financial and other condition and
creditworthiness of the Loan Parties and their respective Subsidiaries, and all
applicable bank or other regulatory Laws relating to the transactions
contemplated hereby, and made its own decision to enter into this Agreement and
to extend credit to the Borrower hereunder. Each Lender also represents that it
will, independently and without reliance upon any Agent-Related Person and based
on such documents and information as it shall deem appropriate at the time,
continue to make its own credit analysis, appraisals and decisions in taking or
not taking action under this Agreement and the other Loan Documents, and to make
such investigations as it deems necessary to inform itself as to the business,
prospects, operations, property, financial and other condition and
creditworthiness of the Borrower and the other Loan Parties. Except for notices,
reports and other documents expressly required to be furnished to the Lenders by
the Administrative Agent herein, the Administrative Agent shall not have any
duty or responsibility to provide any Lender with any credit or other
information concerning the business, prospects, operations,

                                       48
<PAGE>

property, financial and other condition or creditworthiness of any of the Loan
Parties or any of their respective Affiliates which may come into the possession
of any Agent-Related Person.

         9.07 INDEMNIFICATION OF ADMINISTRATIVE AGENT. Whether or not the
transactions contemplated hereby are consummated, the Lenders shall indemnify
upon demand each Agent-Related Person (to the extent not reimbursed by or on
behalf of any Loan Party and without limiting the obligation of any Loan Party
to do so), pro rata, and hold harmless each Agent-Related Person from and
against any and all Indemnified Liabilities incurred by it; provided, however,
that no Lender shall be liable for the payment to any Agent-Related Person of
any portion of such Indemnified Liabilities resulting from such Person's gross
negligence or willful misconduct; provided, however, that no action taken in
accordance with the directions of the Required Lenders shall be deemed to
constitute gross negligence or willful misconduct for purposes of this Section.
Without limitation of the foregoing, each Lender shall reimburse the
Administrative Agent upon demand for its ratable share of any costs or
out-of-pocket expenses (including Attorney Costs) incurred by the Administrative
Agent in connection with the preparation, execution, delivery, administration,
modification, amendment or enforcement (whether through negotiations, legal
proceedings or otherwise) of, or legal advice in respect of rights or
responsibilities under, this Agreement, any other Loan Document, or any document
contemplated by or referred to herein, to the extent that the Administrative
Agent is not reimbursed for such expenses by or on behalf of the Borrower. The
undertaking in this Section shall survive termination of the Commitments, the
payment of all Obligations hereunder and the resignation or replacement of the
Administrative Agent.

         9.08 ADMINISTRATIVE AGENT IN ITS INDIVIDUAL CAPACITY. Bank of America
and its Affiliates may make loans to, accept deposits from, acquire equity
interests in and generally engage in any kind of banking, trust, financial
advisory, underwriting or other business with each of the Loan Parties and their
respective Affiliates as though Bank of America were not the Administrative
Agent hereunder and without notice to or consent of the Lenders. The Lenders
acknowledge that, pursuant to such activities, Bank of America or its Affiliates
may receive information regarding any Loan Party or its Affiliates (including
information that may be subject to confidentiality obligations in favor of such
Loan Party or such Affiliate) and acknowledge that the Administrative Agent
shall be under no obligation to provide such information to them. With respect
to its Loans, Bank of America shall have the same rights and powers under this
Agreement as any other Lender and may exercise such rights and powers as though
it were not the Administrative Agent, and the terms "Lender" and "Lenders"
include Bank of America in its individual capacity.

         9.09 SUCCESSOR ADMINISTRATIVE AGENT. The Administrative Agent may
resign as Administrative Agent upon 30 days' notice to the Lenders and the
Borrower. If the Administrative Agent resigns under this Agreement, the Required
Lenders shall appoint from among the Lenders a successor administrative agent
for the Lenders which successor administrative agent shall be consented to by
the Borrower at all times other than during the existence of an Event of Default
(which consent of the Borrower shall not be unreasonably withheld or delayed).
If no successor administrative agent is appointed prior to the effective date of
the resignation of the Administrative Agent, the Administrative Agent may
appoint, after consulting with the Lenders and the Borrower, a successor
administrative agent from among the Lenders. Upon the acceptance of its
appointment as successor administrative agent hereunder, such successor
administrative agent shall succeed to all the rights, powers and duties of the
retiring Administrative Agent and the term "ADMINISTRATIVE AGENT" shall mean
such successor administrative

                                       49
<PAGE>

agent and the retiring Administrative Agent's appointment, powers and duties as
Administrative Agent shall be terminated. After any retiring Administrative
Agent's resignation hereunder as Administrative Agent, the provisions of this
ARTICLE IX and SECTIONS 10.03 and 10.13 shall inure to its benefit as to any
actions taken or omitted to be taken by it while it was Administrative Agent
under this Agreement. If no successor administrative agent has accepted
appointment as Administrative Agent by the date which is 30 days following a
retiring Administrative Agent's notice of resignation, the retiring
Administrative Agent's resignation shall nevertheless thereupon become effective
and the Lenders shall perform all of the duties of the Administrative Agent
hereunder until such time, if any, as the Required Lenders appoint a successor
agent as provided for above.

         9.10 OTHER AGENTS; LEAD MANAGERS. None of the Lenders or other Persons
identified on the facing page or signature pages of this Agreement as a
"syndication agent," as a "documentation agent," any other type of agent (other
than the Administrative Agent), "joint lead arranger," "joint book manager" or
"lead manager" shall have any right, power, obligation, liability,
responsibility or duty under this Agreement other than those applicable to all
Lenders as such. Without limiting the foregoing, none of the Lenders so
identified shall have or be deemed to have any fiduciary relationship with any
Lender. Each Lender acknowledges that it has not relied, and will not rely, on
any of the Lenders so identified in deciding to enter into this Agreement or in
taking or not taking action hereunder.

                                   ARTICLE X.
                                  MISCELLANEOUS

         10.01 AMENDMENTS, ETC.

         (a) No amendment or waiver of any provision of this Agreement or any
other Loan Document, and no consent to any departure by the Borrower or any
other Loan Party therefrom, shall be effective unless in writing signed by the
Required Lenders and the Borrower or the applicable Loan Party, as the case may
be, and acknowledged by the Administrative Agent, and each such waiver or
consent shall be effective only in the specific instance and for the specific
purpose for which given; provided, however, that no such amendment, waiver or
consent shall, unless in writing and signed by each of the Lenders directly
affected thereby and by the Borrower, and acknowledged by the Administrative
Agent, do any of the following:

                  (i) extend or increase the Commitment of any Lender (or
         reinstate any Commitment terminated pursuant to SECTION 8.02);

                  (ii) postpone any date fixed by this Agreement or any other
         Loan Document for any payment or mandatory prepayment of principal,
         interest, fees or other amounts due to the Lenders (or any of them)
         hereunder or under any other Loan Document;

                  (iii) reduce the principal of, or the rate of interest
         specified herein on, any Loan or (subject to clause (B) of the proviso
         below) any fees or other amounts payable hereunder or under any other
         Loan Document, or change the manner of computation of any financial
         covenant used in determining the Applicable Rate that would result in a
         reduction of any interest rate on any Loan; provided, however, that
         only the consent of the Required Lenders shall be necessary to amend
         the definition of "Default Rate" or to waive any obligation of the
         Borrower to pay interest at the Default Rate; or

                                       50
<PAGE>

                  (iv) amend this Section, or SECTION 2.12, or any provision
         herein providing for unanimous consent or other action by all the
         Lenders;

and, provided further, that (A) no amendment, waiver or consent shall, unless in
writing and signed by the Administrative Agent in addition to the Required
Lenders or all the Lenders, as the case may be, affect the rights or duties of
the Administrative Agent under this Agreement or any other Loan Document; and
(B) the Agent/Arranger Fee Letter may be amended, or rights or privileges
thereunder waived, in a writing executed only by the parties thereto.
Notwithstanding anything to the contrary herein, any Lender that has failed to
fund any portion of the Loans required to be funded by it hereunder shall not
have any right to approve or disapprove any amendment, waiver or consent
hereunder, except that the Pro Rata Share of such Lender may not be increased
without the consent of such Lender.

         (b) Any amendment to any Loan Document which purports to (i) change the
allocation of payments between the Facilities, (ii) decrease the amount of any
mandatory prepayment or commitment reduction required by SECTION 2.04 or (iii)
change this SECTION 10.01(b), must be by an instrument in writing executed by
Borrower, the Administrative Agent and by (A) the Required Term Lenders and (B)
the Required Revolver Lenders.

         10.02 NOTICES AND OTHER COMMUNICATIONS; FACSIMILE COPIES.

         (a) General. Unless otherwise expressly provided herein, all notices
and other communications provided for hereunder and under the other Loan
Documents shall be in writing (including by facsimile transmission) and mailed,
faxed or delivered, to the address, facsimile number or (subject to subsection
(c) below) electronic mail address specified for notices on SCHEDULE 10.02 (for
the Borrower, each Guarantor and the Administrative Agent) or the signature
pages hereto (for the other Lenders); or, in the case of the Borrower, the
Guarantors or the Administrative Agent, to such other address as shall be
designated by such party in a notice to the other parties, and in the case of
any other party, to such other address as shall be designated by such party in a
notice to the Borrower and the Administrative Agent. All such notices and other
communications shall be deemed to be given or made upon the earlier to occur of
(i) actual receipt by the intended recipient and (ii) (A) if delivered by hand
or by courier, when signed for by the intended recipient; (B) if delivered by
mail, four Business Days after deposit in the mails, postage prepaid; (C) if
delivered by facsimile, when sent and receipt has been confirmed by telephone;
and (D) if delivered by electronic mail (which form of delivery is subject to
the provisions of subsection (c) below), when delivered; provided, however, that
notices and other communications to the Administrative Agent pursuant to ARTICLE
II shall not be effective until actually received by such Person. Any notice or
other communication permitted to be given, made or confirmed by telephone
hereunder shall be given, made or confirmed by means of a telephone call to the
intended recipient at the number specified on SCHEDULE 10.02 or such Person's
signature page, as applicable, it being understood and agreed that a voicemail
message shall in no event be effective as a notice, communication or
confirmation hereunder.

         (b) Effectiveness of Facsimile Documents and Signatures. Loan Documents
may be transmitted and/or signed by facsimile. The effectiveness of any such
documents and signatures shall, subject to applicable Law, have the same force
and effect as manually-signed originals and shall be binding on all Loan
Parties, the Administrative Agent and the Lenders. The Administrative Agent may
also require that any such documents and signatures be confirmed by a
manually-signed original thereof; provided, however, that the failure to request
or deliver the same shall not limit the effectiveness of any facsimile document
or signature.

                                       51
<PAGE>

         (c) Limited Use of Electronic Mail. Electronic mail and internet and
intranet websites may be used only to distribute routine communications, such as
financial statements and other information, and to distribute Loan Documents for
execution by the parties thereto, and may not be used for any other purpose.

         (d) Reliance by Administrative Agent and Lenders. The Administrative
Agent and the Lenders shall be entitled to rely and act upon any notices
(including telephonic Borrowing Notices) purportedly given by or on behalf of
the Borrower even if (i) such notices were not made in a manner specified
herein, were incomplete or were not preceded or followed by any other form of
notice specified herein, or (ii) the terms thereof, as understood by the
recipient, varied from any confirmation thereof. The Borrower shall indemnify
each Agent-Related Person and each Lender from all losses, costs, expenses and
liabilities resulting from the reliance by such Person on each notice
purportedly given by or on behalf of the Borrower. All telephonic notices to and
other communications with the Administrative Agent may be recorded by the
Administrative Agent, and each of the parties hereto hereby consents to such
recording.

         10.03 NO WAIVER; CUMULATIVE REMEDIES. No failure by any Lender or the
Administrative Agent to exercise, and no delay by any such Person in exercising,
any right, remedy, power or privilege hereunder shall operate as a waiver
thereof; nor shall any single or partial exercise of any right, remedy, power or
privilege hereunder preclude any other or further exercise thereof or the
exercise of any other right, remedy, power or privilege. The rights, remedies,
powers and privileges herein or therein provided are cumulative and not
exclusive of any rights, remedies, powers and privileges provided by law.

         10.04 ATTORNEY COSTS; EXPENSES AND TAXES. The Borrower agrees (a) to
pay or reimburse the Administrative Agent for all reasonable costs and expenses
incurred in connection with the preparation, negotiation, syndication,
administration and execution of this Agreement and the other Loan Documents and
any amendment, waiver, consent or other modification of the provisions hereof
and thereof (whether or not the transactions contemplated hereby or thereby are
consummated), and the consummation and administration of the transactions
contemplated hereby and thereby, including all Attorney Costs, and (b) to pay or
reimburse the Administrative Agent and each Lender for all costs and expenses
incurred in connection with the enforcement, attempted enforcement, or
preservation of any rights or remedies under this Agreement or the other Loan
Documents (including all such costs and expenses incurred during any workout or
restructuring in respect of the Obligations and during any legal proceeding,
including any proceeding under any Debtor Relief Law), including all Attorney
Costs. The foregoing costs and expenses shall include all other out-of-pocket
expenses incurred by the Administrative Agent and the cost of independent public
accountants and other outside experts retained by the Administrative Agent or
any Lender. The agreements in this Section shall survive the termination of the
Commitments and repayment of all the other Obligations.

         10.05 INDEMNIFICATION. Whether or not the transactions contemplated
hereby are consummated, the Borrower and each Guarantor (by execution of a
Guaranty) agrees to indemnify, save and hold harmless each Agent-Related Person,
each Arranger, each Lender and their respective Affiliates, directors, officers,
employees, counsel, agents and attorneys-in-fact (collectively the
"INDEMNITEES") from and against: (a) any and all claims, demands, actions or
causes of action that are asserted against any Indemnitee by any Person (other
than the Administrative Agent or any Lender) relating directly or indirectly to
a claim, demand, action or cause of action that such Person asserts or may
assert against any Loan Party, any Affiliate of any Loan Party or any of their
respective officers or directors, arising out of or relating to, the Loan
Documents, the Commitments, the use or contemplated use of the proceeds of any
Loans, or the relationship of any Loan Party, the Administrative Agent and the
Lenders under this Agreement or any other Loan Document; (b) any and all claims,
demands, actions or causes of action that may at any time (including at any time
following repayment of the Obligations and the resignation of the

                                       52
<PAGE>

Administrative Agent or the replacement of any Lender) be asserted or imposed
against any Indemnitee, arising out of or relating to, the Loan Documents, the
Commitments, the use or contemplated use of the proceeds of any Loans, or the
relationship of any Loan Party, the Administrative Agent and the Lenders under
this Agreement or any other Loan Document; (c) without limiting the foregoing,
any and all claims, demands, actions or causes of action that are asserted or
imposed against any Indemnitee, (i) under the application of any Environmental
Law applicable to the Borrower or any of its Subsidiaries or any of their
properties or assets, including the treatment or disposal of Hazardous
Substances on any of their properties or assets, (ii) as a result of the breach
or non-compliance by the Borrower or any Subsidiary with any Environmental Law
applicable to the Borrower or any Subsidiary, (iii) due to past ownership by the
Borrower or any Subsidiary of any of their properties or assets or past activity
on any of their properties or assets which, though lawful and fully permissible
at the time, could result in present liability, (iv) due to the presence, use,
storage, treatment or disposal of Hazardous Substances on or under, or the
escape, seepage, leakage, spillage, discharge, emission or release from, any of
the properties owned or operated by the Borrower or any Subsidiary (including
any liability asserted or arising under any Environmental Law), regardless of
whether caused by, or within the control of, the Borrower or such Subsidiary, or
(v) due to any other environmental, health or safety condition in connection
with the Loan Documents; (d) any administrative or investigative proceeding by
any Governmental Authority arising out of or related to a claim, demand, action
or cause of action described in subsection (a), (b) or (c) above; and (e) any
and all liabilities (including liabilities under indemnities), losses, costs or
expenses (including Attorney Costs) that any Indemnitee suffers or incurs as a
result of the assertion of any foregoing claim, demand, action, cause of action
or proceeding, or as a result of the preparation of any defense in connection
with any foregoing claim, demand, action, cause of action or proceeding, in all
cases, WHETHER OR NOT ARISING OUT OF THE NEGLIGENCE OF AN INDEMNITEE, and
whether or not an Indemnitee is a party to such claim, demand, action, cause of
action or proceeding (all the foregoing, collectively, the "INDEMNIFIED
LIABILITIES"); provided that no Indemnitee shall be entitled to indemnification
for any claim caused by its own gross negligence or willful misconduct. The
agreements in this Section shall survive the termination of the Commitments and
repayment of all the other Obligations.

         10.06 PAYMENTS SET ASIDE. To the extent that the Borrower makes a
payment to the Administrative Agent or any Lender, or the Administrative Agent
or any Lender exercises its right of set-off, and such payment or the proceeds
of such set-off or any part thereof is subsequently invalidated, declared to be
fraudulent or preferential, set aside or required (including pursuant to any
settlement entered into by the Administrative Agent or such Lender in its
discretion) to be repaid to a trustee, receiver or any other party, in
connection with any proceeding under any Debtor Relief Law or otherwise, then
(a) to the extent of such recovery, the obligation or part thereof originally
intended to be satisfied shall be revived and continued in full force and effect
as if such payment had not been made or such set-off had not occurred, and (b)
each Lender severally agrees to pay to the Administrative Agent upon demand its
applicable share of any amount so recovered from or repaid by the Administrative
Agent, plus interest thereon from the date of such demand to the date such
payment is made at a rate per annum equal to the Federal Funds Rate from time to
time in effect.

         10.07 SUCCESSORS AND ASSIGNS.

         (a) The provisions of this Agreement shall be binding upon and inure to
the benefit of the parties hereto and their respective successors and assigns
permitted hereby, except that the Borrower may not assign or otherwise transfer
any of its rights or obligations hereunder without the prior written consent of
each Lender (and any attempted assignment or transfer by the Borrower without
such consent shall be null and void). Nothing in this Agreement, expressed or
implied, shall be construed to confer upon any Person (other than the parties
hereto, their respective successors and assigns permitted hereby and, to the

                                       53
<PAGE>

extent expressly contemplated hereby, the Indemnitees) any legal or equitable
right, remedy or claim under or by reason of this Agreement.

         (b) Any Lender may assign to one or more Eligible Assignees all or a
portion of its rights and obligations under this Agreement (including all or a
portion of its Commitment and the Loans at the time owing to it); provided that
(i) except in the case of an assignment of the entire remaining amount of the
assigning Lender's Commitment and the Loans at the time owing to it or in the
case of an assignment to a Lender or an Affiliate of a Lender, the aggregate
amount of the Commitment (which for this purpose includes Loans outstanding
thereunder) of the assigning Lender subject to each such assignment, determined
as of the date the Assignment and Acceptance with respect to such assignment is
delivered to the Administrative Agent, shall not be less than $1,000,000 in the
case of any assignment of a Revolver Commitment and Revolver Principal Debt, or
$5,000,000 in the case of any assignment of any Term Loan Principal Debt, unless
each of the Administrative Agent and, so long as no Event of Default has
occurred and is continuing, the Borrower otherwise consents (each such consent
not to be unreasonably withheld or delayed), (ii) each partial assignment shall
be made as an assignment of a proportionate part of all the assigning Lender's
rights and obligations under this Agreement with respect to the Loans or the
Commitment assigned, except that this clause (ii) shall not prohibit the
assignment of a proportionate part of all the assigning Lender's rights and
obligations in respect of one Facility, and (iii) the parties to each assignment
shall execute and deliver to the Administrative Agent an Assignment and
Acceptance, together with a processing and recordation fee of $3,500 (such fee
to be paid by the assignor or the assignee, as may be agreed between them). An
assignment need not be ratable as between the Term Loan Facility and the
Revolver Facility. Subject to acceptance and recording thereof by the
Administrative Agent pursuant to subsection (c) of this Section, from and after
the effective date specified in each Assignment and Acceptance, the Eligible
Assignee thereunder shall be a party hereto and, to the extent of the interest
assigned by such Assignment and Acceptance, have the rights and obligations of a
Lender under this Agreement, and the assigning Lender thereunder shall, to the
extent of the interest assigned by such Assignment and Acceptance, be released
from its obligations under this Agreement (and, in the case of an Assignment and
Acceptance covering all of the assigning Lender's rights and obligations under
this Agreement, such Lender shall cease to be a party hereto but shall continue
to be entitled to the benefits of SECTIONS 3.07, 10.04 and 10.05). Upon request,
the Borrower (at its expense) shall execute and deliver new or replacement Notes
to the assigning Lender and the assignee Lender. Any assignment or transfer by a
Lender of rights or obligations under this Agreement that does not comply with
this subsection shall be treated for purposes of this Agreement as a sale by
such Lender of a participation in such rights and obligations in accordance with
subsection (d) of this Section.

         (c) The Administrative Agent, acting solely for this purpose as an
agent of the Borrower, shall maintain at the Administrative Agent's Office a
copy of each Assignment and Acceptance delivered to 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 pursuant to the terms
hereof from time to time (the "REGISTER"). The entries in the Register shall be
conclusive, and the Borrower, the Administrative Agent and the Lenders may treat
each Person whose name is recorded in the Register pursuant to the terms hereof
as a Lender hereunder for all purposes of this Agreement, notwithstanding notice
to the contrary. The Register shall be available for inspection by the Borrower
and any Lender, at any reasonable time and from time to time upon reasonable
prior notice.

         (d) Any Lender may, without the consent of, or notice to, the Borrower
or the Administrative Agent, sell participations to one or more banks or other
entities (a "PARTICIPANT") in all or a portion of such Lender's rights and/or
obligations under this Agreement (including all or a portion of its Commitment
and/or the Loans owing to it); provided that (i) such Lender's obligations under
this Agreement shall

                                       54
<PAGE>

remain unchanged, (ii) such Lender shall remain solely responsible to the other
parties hereto for the performance of such obligations and (iii) the Borrower,
the Administrative Agent 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. Any agreement or instrument pursuant to which
a Lender sells such a participation shall provide that such Lender shall retain
the sole right to enforce this Agreement and to approve any amendment,
modification or waiver of any provision of this Agreement; provided that such
agreement or instrument may provide that such Lender will not, without the
consent of the Participant, agree to any amendment, waiver or other modification
that would (i) postpone any date upon which any payment of money is scheduled to
be paid to such Participant, (ii) reduce the principal, interest, fees or other
amounts payable to such Participant, or (iii) release any Guarantor from the
Guaranty. Subject to subsection (e) of this Section, the Borrower agrees that
each Participant shall be entitled to the benefits of SECTIONS 3.01, 3.04 and
3.05 to the same extent as if it were a Lender and had acquired its interest by
assignment pursuant to subsection (b) of this Section. To the extent permitted
by law, each Participant also shall be entitled to the benefits of SECTION 10.09
as though it were a Lender, provided such Participant agrees to be subject to
SECTION 2.12 as though it were a Lender.

         (e) A Participant shall not be entitled to receive any greater payment
under SECTION 3.01 or 3.04 than the applicable Lender would have been entitled
to receive with respect to the participation sold to such Participant, unless
the sale of the participation to such Participant is made with the Borrower's
prior written consent. A Participant that would be a Foreign Lender if it were a
Lender shall not be entitled to the benefits of SECTION 3.01 unless the Borrower
is notified of the participation sold to such Participant and such Participant
agrees, for the benefit of the Borrower, to comply with SECTION 10.15 as though
it were a Lender.

         (f) Any Lender may at any time pledge or assign a security interest in
all or any portion of its rights under this Agreement (including under its
Notes, if any) to secure obligations of such Lender, including any pledge or
assignment to secure obligations to a Federal Reserve Bank; provided that no
such pledge or assignment shall release a Lender from any of its obligations
hereunder or substitute any such pledgee or assignee for such Lender as a party
hereto.

         (g) If the consent of the Borrower to an assignment or to an Eligible
Assignee is required hereunder (including a consent to an assignment which does
not meet the minimum assignment threshold specified in clause (i) of the proviso
to the first sentence of SECTION 10.07(b)), the Borrower shall be deemed to have
given its consent five Business Days after the date notice thereof has been
delivered by the assigning Lender (through the Administrative Agent) unless such
consent is expressly refused by the Borrower prior to such fifth Business Day.

         10.08 CONFIDENTIALITY. Each Lender agrees that it will not disclose
without the prior consent of the Borrower (other than to directors, officers,
employees, auditors, accountants, counsel or other professional advisors of the
Administrative Agent or any Lender) any information with respect to the Borrower
or its Subsidiaries, which is furnished pursuant to this Agreement and which (i)
the Borrower in good faith considers to be confidential and (ii) is either
clearly marked confidential or is designated by the Borrower to the
Administrative Agent or the Lenders in writing as confidential, provided that
any Lender may disclose any such information (a) as has become generally
available to the public, (b) as may be required or appropriate in any report,
statement or testimony submitted to or required by any municipal, state or
federal regulatory body having or claiming to have jurisdiction over such Lender
or submitted to or required by the Board or the Federal Deposit Insurance
Corporation or similar organizations (whether in the United States of America or
elsewhere) or their successors, (c) as may be required or appropriate in
response to any summons or subpoena in connection with any litigation, (d) in
order to comply with any

                                       55
<PAGE>

law, order, regulation or ruling applicable to such Lender, (e) to any Eligible
Assignee of or Participant in, or any prospective Eligible Assignee of or
Participant in, any of its rights or obligations under this Agreement, provided
that such Eligible Assignee or Participant or prospective Eligible Assignee or
Participant executes an agreement containing provisions substantially similar to
those contained in this SECTION 10.08, (f) in connection with the exercise of
any remedy by such Lender following an Event of Default pertaining to the Loan
Documents, (g) in connection with any litigation involving such Lender
pertaining to the Loan Documents, (h) to any Lender or the Administrative Agent,
or (i) to any Affiliate of any Lender (it being understood that the Persons to
whom such disclosure is made will be informed of the confidential nature of such
information and instructed to keep such information confidential).

         10.09 SET-OFF. In addition to any rights and remedies of the Lenders
provided by law, upon the occurrence and during the continuance of any Event of
Default, each Lender is authorized at any time and from time to time, without
prior notice to the Borrower or any other Loan Party, any such notice being
waived by the Borrower (on its own behalf and on behalf of each Loan Party) to
the fullest extent permitted by law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held by,
and other indebtedness at any time owing by, such Lender to or for the credit or
the account of the respective Loan Parties against any and all Obligations owing
to the Administrative Agent and the Lenders, now or hereafter existing,
irrespective of whether or not the Administrative Agent or such Lender shall
have made demand under this Agreement or any other Loan Document and although
such Obligations may be contingent or unmatured. Each Lender agrees promptly to
notify the Borrower and the Administrative Agent after any such set-off and
application made by such Lender; provided, however, that the failure to give
such notice shall not affect the validity of such set-off and application.

         10.10 INTEREST RATE LIMITATION. Regardless of any provision contained
in any Loan Document, neither the Administrative Agent nor any Lender shall ever
be entitled to contract for, charge, take, reserve, receive, or apply, as
interest on all or any part of the Obligations, any amount in excess of the
Maximum Rate, and, if any Lender ever does so, then such excess shall be deemed
a partial prepayment of principal and treated hereunder as such and any
remaining excess shall be refunded to the Borrower. In determining if the
interest paid or payable exceeds the Maximum Rate, the Borrower and the Lenders
shall, to the maximum extent permitted under applicable Law, (a) treat all
Borrowings as but a single extension of credit (and the Lenders and the Borrower
agree that such is the case and that provision herein for multiple Borrowings is
for convenience only), (b) characterize any nonprincipal payment as an expense,
fee, or premium rather than as interest, (c) exclude voluntary prepayments and
the effects thereof, and (d) amortize, prorate, allocate, and spread the total
amount of interest throughout the entire contemplated term of the Obligations.
However, if the Obligations are paid and performed in full prior to the end of
the full contemplated term thereof, and if the interest received for the actual
period of existence thereof exceeds the Maximum Amount, the Lenders shall refund
such excess, and, in such event, the Lenders shall not, to the extent permitted
by Law, be subject to any penalties provided by any Laws for contracting for,
charging, taking, reserving, or receiving interest in excess of the Maximum
Amount. If, contrary to the parties' intent expressed in SECTION 10.16(a), the
Laws of the State of Texas are applicable for purposes of determining the
"Maximum Rate" or the "Maximum Amount," then those terms mean the "weekly
ceiling" from time to time in effect under Texas Finance Code Section 303.305,
as amended. The Borrower agrees that Chapter 346 of the Texas Finance Code, as
amended (which regulates certain revolving credit loan accounts and revolving
tri-party accounts), does not apply to the Obligations.

                                       56
<PAGE>

         10.11 COUNTERPARTS. This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

         10.12 INTEGRATION. This Agreement, together with the other Loan
Documents, comprises the complete and integrated agreement of the parties on the
subject matter hereof and thereof and supersedes all prior agreements, written
or oral, on such subject matter. In the event of any conflict between the
provisions of this Agreement and those of any other Loan Document, the
provisions of this Agreement shall control; provided that the inclusion of
supplemental rights or remedies in favor of the Administrative Agent or the
Lenders in any other Loan Document shall not be deemed a conflict with this
Agreement. Each Loan Document was drafted with the joint participation of the
respective parties thereto and shall be construed neither against nor in favor
of any party, but rather in accordance with the fair meaning thereof.

         10.13 SURVIVAL OF REPRESENTATIONS AND WARRANTIES. All representations
and warranties made hereunder and in any other Loan Document or other document
delivered pursuant hereto or thereto or in connection herewith or therewith
shall survive the execution and delivery hereof and thereof. Such
representations and warranties have been or will be relied upon by the
Administrative Agent and each Lender, regardless of any investigation made by
the Administrative Agent or any Lender or on their behalf and notwithstanding
that the Administrative Agent or any Lender may have had notice or knowledge of
any Default or Event of Default at the time of any Borrowing, and shall continue
in full force and effect as long as any Loan or any other Obligation shall
remain unpaid or unsatisfied.

         10.14 SEVERABILITY. Any provision of this Agreement and the other Loan
Documents to which the Borrower is a party 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 thereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

         10.15 FOREIGN LENDERS. Each Lender that is a "foreign corporation,
partnership or trust" within the meaning of the Code (a "FOREIGN LENDER") shall
deliver to the Administrative Agent, prior to receipt of any payment subject to
withholding under the Code (or after accepting an assignment of an interest
herein), two duly signed completed copies of either IRS Form W-8BEN or any
successor thereto (relating to such Person and entitling it to an exemption
from, or reduction of, withholding tax on all payments to be made to such Person
by the Borrower pursuant to this Agreement) or IRS Form W-8ECI or any successor
thereto (relating to all payments to be made to such Person by the Borrower
pursuant to this Agreement) or such other evidence satisfactory to the Borrower
and the Administrative Agent that such Person is entitled to an exemption from,
or reduction of, U.S. withholding tax. Thereafter and from time to time, each
such Person shall (a) promptly submit to the Administrative Agent such
additional duly completed and signed copies of one of such forms (or such
successor forms as shall be adopted from time to time by the relevant United
States taxing authorities) as may then be available under then current United
States laws and regulations to avoid, or such evidence as is satisfactory to the
Borrower and the Administrative Agent of any available exemption from or
reduction of, United States withholding taxes in respect of all payments to be
made to such Person by the Borrower pursuant to this Agreement, (b) promptly
notify the Agent of any change in circumstances which would modify or render
invalid any claimed exemption or reduction, and (c) take such steps as shall not
be materially disadvantageous to it, in the reasonable judgment of such Lender,
and as may be reasonably necessary (including the re-designation of its Lending
Office) to avoid any requirement of applicable Laws that the Borrower make any
deduction or withholding for taxes from amounts payable to such Person. If such
Person fails to deliver the above forms or other documentation, then the
Administrative Agent may withhold from any interest payment to such Person an
amount equivalent to the applicable withholding tax imposed by Sections 1441 and
1442 of

                                       57
<PAGE>

the Code, without reduction. If any Governmental Authority asserts that the
Administrative Agent did not properly withhold any tax or other amount from
payments made in respect of such Person, such Person shall indemnify the
Administrative Agent therefor, including all penalties and interest, any taxes
imposed by any jurisdiction on the amounts payable to the Agent under this
Section, and costs and expenses (including Attorney Costs) of the Administrative
Agent. The obligation of the Lenders under this Section shall survive the
payment of all Obligations and the resignation or replacement of the
Administrative Agent.

         10.16 GOVERNING LAW.

         (a) THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE
WITH, THE LAW OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE
PERFORMED ENTIRELY WITHIN SUCH STATE; PROVIDED THAT THE ADMINISTRATIVE AGENT AND
EACH LENDER SHALL RETAIN ALL RIGHTS ARISING UNDER FEDERAL LAW.

         (b) EACH COMPANY AND OTHER PARTY HERETO, AND EACH GUARANTOR, BY
EXECUTION OF A GUARANTY, AGREES AS TO THIS SECTION 10.16(b). ANY LEGAL ACTION OR
PROCEEDING WITH RESPECT TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT MAY BE
BROUGHT IN THE COURTS OF THE STATE OF NEW YORK SITTING IN THE BOROUGH OF
MANHATTAN OR OF THE UNITED STATES FOR THE SOUTHERN DISTRICT OF SUCH STATE, AND
BY EXECUTION AND DELIVERY OF THIS AGREEMENT, THE BORROWER, THE ADMINISTRATIVE
Agent AND EACH LENDER CONSENTS, AND BY EXECUTION OF A GUARANTY, EACH GUARANTOR
CONSENTS, FOR ITSELF AND IN RESPECT OF ITS PROPERTY, TO THE NON-EXCLUSIVE
JURISDICTION OF THOSE COURTS. THE BORROWER, EACH GUARANTOR, THE ADMINISTRATIVE

Borrower and the Guarantors, and that no judgment, order or execution entered in
any suit, action or proceeding, whether legal or equitable, on this Agreement,
such Note or any of the other Loan Documents shall be obtained or enforced
against the General Partner or its assets for the purpose of obtaining
satisfaction and payment of such Note, the Indebtedness evidenced thereby or any
claims arising thereunder or under this Agreement or any other Loan Document,
any right to proceed against the General Partner individually or its respective
assets being hereby expressly waived, renounced and remitted by the Lenders for
themselves and their respective successors and assigns. Nothing in this SECTION
10.18, however, shall be construed so as to prevent the Administrative Agent,
any Lender or any other holder of any Note from commencing any action, suit or
proceeding with respect to or causing legal papers to be served upon the General
Partner for the purpose of obtaining jurisdiction over Borrower.

         10.19 ENTIRE AGREEMENT. This Agreement and the other Loan Documents
represent the final agreement between the parties and may not be contradicted by
evidence of prior, contemporaneous, or subsequent oral agreements of the
parties. There are no unwritten oral agreements between the parties.

Assignee as a Lender under the Agreement, effective as of the Effective Date
with respect to the Assigned Interest, and will adjust the registered Pro Rata

                                FORM OF GUARANTY

         THIS GUARANTY is executed as of February 6, 2001, jointly and severally
by the undersigned (each a "GUARANTOR" and collectively the "GUARANTORS"), for
the benefit of BANK OF AMERICA, N.A., a national banking association (in its
capacity as Administrative Agent for the benefit of Lenders).

                                    RECITALS

         A. Williams OLP, L.P., a Delaware limited partnership ("BORROWER"),
Bank of America, N.A., as Administrative Agent (including its permitted
successors and assigns in such capacity, "ADMINISTRATIVE AGENT"), Lehman
Commercial Paper, Inc., as Syndication Agent, SunTrust Bank, as Documentation
Agent, and the Lenders now or hereafter party to the Credit Agreement (including
their respective permitted successors and assigns, "Lenders") have entered into
a Credit Agreement, dated as of February 6, 2001 (as amended, modified,
supplemented, or restated from time to time, the "CREDIT AGREEMENT");

         B. Provisions of the Credit Agreement permit Guarantors to directly or
indirectly receive proceeds of Borrowings made pursuant thereto; and

         C. This Guaranty is integral to the transactions contemplated by the
Loan Documents and the execution and delivery hereof, is a condition precedent
to Lenders' obligations to extend credit under the Loan Documents.

         ACCORDINGLY, for adequate and sufficient consideration, the receipt and
adequacy of which are hereby acknowledged, each Guarantor, jointly and
severally, guarantees to Administrative Agent and Lenders the prompt payment of
the Guaranteed Debt (defined below) as follows:

         1. DEFINITIONS. Terms defined in the Credit Agreement have the same
meanings when used, unless otherwise defined, in this Guaranty. As used in this
Guaranty:

         BORROWER means Borrower, Borrower as a debtor-in-possession, and any
receiver, trustee, liquidator, conservator, custodian, or similar party
appointed for Borrower or for all or substantially all of Borrower's assets
under any Debtor Relief Law.

         CREDIT AGREEMENT is defined in the recitals to this Guaranty.

         GUARANTEED DEBT means, collectively, (a) the Obligations and (b) all
present and future costs, attorneys' fees, and expenses reasonably incurred by
Administrative Agent or any Lender to enforce Borrower's, any Guarantor's, or
any other obligor's payment of any of the Guaranteed Debt, including, without
limitation (to the extent lawful), all present and future amounts that would
become due but for the operation of Sections 502 or 506 or any other provision
of Title 11 of the United States Code and all present and future accrued and
unpaid interest (including, without limitation, all post-maturity interest and
any post-petition interest in any proceeding under Debtor Relief Laws to which
Borrower or any Guarantor becomes subject).

         GUARANTOR and GUARANTORS is defined in the preamble to this Guaranty.

                                   Exhibit E
                                     Page 1
                                Form of Guaranty

<PAGE>

         LENDER means, individually, or LENDERS means, collectively, on any date
of determination, the Lenders and their permitted successors and assigns.

         SUBORDINATED DEBT means, for each Guarantor, all present and future
obligations of any Company to such Guarantor, whether those obligations are (a)
direct, indirect, fixed, contingent, liquidated, unliquidated, joint, several,
or joint and several, (b) due or to become due to such Guarantor, (c) held by or
are to be held by such Guarantor, (d) created directly or acquired by assignment
or otherwise, or (e) evidenced in writing.

         2. GUARANTY. This is an absolute, irrevocable, and continuing guaranty
of payment, not collection, and the circumstance that at any time or from time
to time the Guaranteed Debt may be paid in full does not affect the obligation
of any Guarantor with respect to the Guaranteed Debt incurred after that. This
Guaranty remains in effect until the Guaranteed Debt is fully paid and
performed, and all commitments to extend any credit under the Loan Documents
have terminated. No Guarantor may rescind or revoke its obligations with respect
to the Guaranteed Debt. Notwithstanding any contrary provision, it is the
intention of Guarantors, Lenders, and Administrative Agent that the amount of
the Guaranteed Debt guaranteed by each Guarantor by this Guaranty shall be in,
but not in excess of, the maximum amount permitted by fraudulent conveyance,
fraudulent transfer, or similar Laws applicable to each such Guarantor.
Accordingly, notwithstanding anything to the contrary contained in this Guaranty
or any other agreement or instrument executed in connection with the payment of
any of the Guaranteed Debt, the amount of the Guaranteed Debt guaranteed by any
Guarantor under this Guaranty shall be limited to an aggregate amount equal to
the largest amount that would not render such Guarantor's obligations hereunder
subject to avoidance under Section 548 of the United States Bankruptcy Code or
any comparable provision of any applicable state Law.

         3. CONSIDERATION. Each Guarantor represents and warrants that its
liability under this Guaranty may reasonably be expected to directly or
indirectly benefit it.

         4. CUMULATIVE RIGHTS. If any Guarantor becomes liable for any
indebtedness owing by Borrower to Administrative Agent or any Lender, other than
under this Guaranty, that liability may not be in any manner impaired or
affected by this Guaranty. The Rights of Administrative Agent or Lenders under
this Guaranty are cumulative of any and all other Rights that Administrative
Agent or Lenders may ever have against any Guarantor. The exercise by
Administrative Agent or Lenders of any Right under this Guaranty or otherwise
does not preclude the concurrent or subsequent exercise of any other Right.

         5. PAYMENT UPON DEMAND. If an Event of Default exists, each Guarantor
shall, on demand and without further notice of dishonor and without any notice
having been given to any Guarantor previous to that demand of either the
acceptance by Administrative Agent or Lenders of this Guaranty or the creation
or incurrence of any Guaranteed Debt, pay the amount of the Guaranteed Debt then
due and payable to Administrative Agent and Lenders; provided that, if an Event
of Default exists and Administrative Agent or Lenders cannot, for any reason,
accelerate the Obligations, then the Guaranteed Debt shall be, as among
Guarantors, Administrative Agent, and Lenders, a fully matured, due, and payable
obligation of Guarantors to Administrative Agent and Lenders. It is not
necessary for Administrative Agent or Lenders, in order to enforce that payment
by any Guarantor, first or contemporaneously to institute suit or exhaust
remedies against Borrower or others liable on any Guaranteed Debt.

                                   Exhibit E

                                Form of Guaranty

<PAGE>

         6. SUBORDINATION. The Subordinated Debt is expressly subordinated to
the full and final payment of the Guaranteed Debt. Upon the occurrence and
during the continuation of an Event of Default, each Guarantor agrees not to
accept any payment of any Subordinated Debt from any Company. If any Guarantor
receives any payment of any Subordinated Debt in violation of the foregoing,
such Guarantor shall hold that payment in trust for Administrative Agent and
Lenders and promptly turn it over to Administrative Agent, in the form received
(with any necessary endorsements), to be applied to the Guaranteed Debt.

         7. SUBROGATION AND CONTRIBUTION. Until payment in full of the
Guaranteed Debt and the termination of the Obligations of Lenders to extend
credit under the Loan Documents, (a) no Guarantor may assert, enforce, or
otherwise exercise any Right of subrogation to any of the Rights or Liens of
Administrative Agent or Lenders or any other beneficiary against Borrower or any
other obligor on the Guaranteed Debt or any Collateral or other security or any
Right of recourse, reimbursement, subrogation, contribution, indemnification, or
similar Right against Borrower or any other obligor on any Guaranteed Debt or
any Guarantor of it, and (b) each Guarantor defers all of the foregoing Rights
(whether they arise in equity, under contract, by statute, under common Law, or
otherwise). Upon payment in full of the Guaranteed Debt and the termination of
the obligations of Lenders to extend credit under the Loan Documents, each
Guarantor shall be subrogated to the rights of the Administrative Agent and
Lenders against Borrower and the other obligors.

         8. NO RELEASE. Each Guarantor agrees that its obligations under this
Guaranty may not be released, diminished, or affected by the occurrence of any
one or more of the following events: (a) any taking or accepting of any
additional guaranty or any other security or assurance for any Guaranteed Debt;
(b) any release, surrender, exchange, subordination, impairment, or loss of any
Collateral securing any Guaranteed Debt; (c) any full or partial release of the
liability of any other obligor on the Obligations, except for any final release
resulting from payment in full of such Obligations; (d) the modification of, or
waiver of compliance with, any terms of any other Loan Document; (e) the
insolvency, bankruptcy, or lack of corporate or partnership power of any other
obligor at any time liable for any Guaranteed Debt, whether now existing or
occurring in the future; (f) any renewal, extension, or rearrangement of any
Guaranteed Debt or any adjustment, indulgence, forbearance, or compromise that
may be granted or given by Administrative Agent or any Lender to any other
obligor on the Obligations; (g) any neglect, delay, omission, failure, or
refusal of Administrative Agent or any Lender to take or prosecute any action in
connection with the Guaranteed Debt or to foreclose, take, or prosecute any
action in connection with any Loan Document; (h) any failure of Administrative
Agent or any Lender to notify any Guarantor of any renewal, extension, or
assignment of any Guaranteed Debt, or the release of any security or of any
other action taken or refrained from being taken by Administrative Agent or any
Lender against Borrower or any new agreement between Administrative Agent, any
Lender, and Borrower; it being understood that neither Administrative Agent nor
any Lender is required to give any Guarantor any notice of any kind under any
circumstances whatsoever with respect to or in connection with any Guaranteed
Debt, other than any notice required to be given in this Guaranty; (i) the
unenforceability of any Guaranteed Debt against any other obligor or any
security securing same because it exceeds the amount permitted by Law, the act
of creating it is ultra vires, the officers creating it exceeded their authority
or violated their fiduciary duties in connection with it, or otherwise; (j) any
payment of the Obligations to Administrative Agent or any Lender is held to
constitute a preference under any Debtor Relief Law or for any other reason
Administrative Agent or any Lender is required to refund that payment or make
payment to someone else (and in each such instance this Guaranty will be
reinstated in an amount equal to that payment); or (k) any other circumstance
which might otherwise constitute a defense available to, or a legal or equitable
discharge of, Borrower or any Guarantor.

                                   Exhibit E

                                Form of Guaranty
<PAGE>

         9. WAIVERS. By execution hereof, each Guarantor waives presentment and
demand for payment, protest, notice of intention to accelerate, notice of
acceleration, and notice of protest and nonpayment, and agrees that its
liability with respect to the Guaranteed Debt (or any part thereof) shall not be
affected by any renewal or extension in the time of payment of the Obligations
(or any part thereof). To the maximum extent lawful, each Guarantor waives all
Rights by which it might be entitled to require suit on an accrued Right of
action in respect of any Guaranteed Debt or require suit against Borrower or
others.

         10. LOAN DOCUMENTS. By execution hereof, each Guarantor covenants and
agrees that certain representations, warranties, terms, covenants, and
conditions set forth in the Loan Documents are applicable to Guarantors by their
terms and shall be imposed upon Guarantors, and each Guarantor reaffirms that
each such representation and warranty is true and correct and covenants and
agrees to promptly and properly perform, observe, and comply with each such
term, covenant, or condition. Moreover, each Guarantor acknowledges and agrees
that this Guaranty is subject to the offset provisions of the Loan Documents in
favor of Administrative Agent and Lenders. In the event the Credit Agreement or
any other Loan Document shall cease to remain in effect for any reason
whatsoever during any period when any part of the Guaranteed Debt remains
unpaid, the terms, covenants, and agreements of the Credit Agreement or such
other Loan Document incorporated herein by reference shall nevertheless continue
in full force and effect as obligations of Guarantors under this Guaranty.

         11. RELIANCE AND DUTY TO REMAIN INFORMED. Each Guarantor confirms that
it has executed and delivered this Guaranty after reviewing the terms and
conditions of the Loan Documents and such other information as it has deemed
appropriate in order to make its own credit analysis and decision to execute and
deliver this Guaranty. Each Guarantor confirms that it has made its own
independent investigation with respect to Borrower's creditworthiness and is not
executing and delivering this Guaranty in reliance on any representation or
warranty by Administrative Agent or any Lender as to that creditworthiness. Each
Guarantor expressly assumes all responsibilities to remain informed of the
financial condition of Borrower and any circumstances affecting Borrower's
ability to perform under the Loan Documents to which it is a party.

         12. LOAN DOCUMENT. This Guaranty is a Loan Document and is subject to
the applicable provisions of ARTICLES 1 and 10 of the Credit Agreement,
including, without limitation, the provisions relating to GOVERNING LAW, AND
WAIVER OF RIGHT TO JURY TRIAL, both of which are incorporated into this Guaranty
by reference the same as if set forth in this Guaranty verbatim.

         13. NOTICES. All notices required or permitted under this Guaranty, if
any, shall be given in the manner set forth in Section 10.02 of the Credit
Agreement.

         14. AMENDMENTS, ETC. No amendment, waiver, or discharge to or under
this Guaranty is valid unless it is in writing and is signed by the party
against whom it is sought to be enforced and is otherwise in conformity with the
requirements of SECTION 10.01 of the Credit Agreement.

         15. ADMINISTRATIVE AGENT AND LENDERS. Administrative Agent is
Administrative Agent for each Lender under the Credit Agreement. All Rights
granted to Administrative Agent under or in connection with this Guaranty are
for each Lender's ratable benefit. Administrative Agent may, without the joinder
of any Lender, exercise any Rights in Administrative Agent's or Lenders' favor
under or in connection with this Guaranty. Administrative Agent's and each
Lender's Rights and obligations vis-a-vis each other may be subject to one or
more separate agreements between those parties.

                                   Exhibit E
                                     Page 4
                                Form of Guaranty
<PAGE>

However, no Guarantor is required to inquire about any such agreement or is
subject to any of its terms unless such Guarantor specifically joins such
agreement Therefore, neither Guarantor nor its successors or assigns is entitled
to any benefits or provisions of any such separate agreement or is entitled to
rely upon or raise as a defense any party's failure or refusal to comply with
the provisions of such agreement.

         16. ADDITIONAL GUARANTORS. From time to time subsequent to the time
hereof, additional Persons may execute and deliver guaranties to the
Administrative Agent. Each Guarantor hereunder expressly agrees that its
obligations arising hereunder shall not be affected or diminished by any such
additional guaranties.

         17. PARTIES. This Guaranty benefits Administrative Agent, Lenders, and
their respective successors and assigns and binds Guarantors and their
respective successors and assigns. Upon appointment of any successor
Administrative Agent under the Credit Agreement, all of the Rights of
Administrative Agent under this Guaranty automatically vest in that new
Administrative Agent as successor Administrative Agent on behalf of Lenders
without any further act, deed, conveyance, or other formality other than that
appointment. The Rights of Administrative Agent and Lenders under this Guaranty
may be transferred with any assignment of the Guaranteed Debt pursuant to and in
accordance with the terms of the Credit Agreement. The Credit Agreement contains
provisions governing assignments of the Guaranteed Debt and of Rights and
obligations under this Guaranty.

                           FORM OF OPINION OF COUNSEL

                                February __, 2001

To each of the Lenders parties to the Credit
Agreement referred to below, and
Bank of America, N.A., as
Administrative Agent for the Lenders

Ladies and Gentlemen:

         We have acted as special counsel to (i) Williams OLP, L.P. (the

with the Credit Agreement dated as of February 6, 2001, by and among the
Borrower, the Lenders party thereto, Bank of America, N.A., as Administrative

SunTrust Bank, as Documentation Agent (the "Credit Agreement").

         This opinion is furnished to you at the request of the Borrower

         (b)      the Notes;

         (c)      the Guaranty executed by the Guarantors;

                  dated the date hereof or the date of the Credit Agreement, as
                  the case may be;

         (e)      copies of such corporate documents and records of the Loan
                  Parties, certificates of officers and representatives of
                  certain of the Loan Parties, and such other agreements,

                  and other Persons as we have deemed necessary or appropriate
                  for the purposes of rendering the opinion expressed herein;
                  and

         (f)      such matters of law as we have deemed necessary or appropriate
                  as a basis for the opinion expressed herein.

<PAGE>

B.       ASSUMPTIONS

         In rendering the opinion expressed below, we have assumed, with your
permission, without independent investigation or inquiry, (a) the due
authorization, execution and delivery of the Loan Documents by all parties to
such documents (other than the Loan Parties) and that the Loan Documents are
valid, binding and enforceable (subject to the limitations on enforceability of
the types referred to in the qualifications below) against the parties thereto
(other than the Loan Parties), (b) the legal capacity of natural persons, (c)
the genuineness of all signatures on all documents that we examined, (d) the
authenticity of all documents submitted to us as originals, and (e) the
conformity to authentic originals of all documents submitted to us as certified,
conformed or photostatic copies.

         As to questions of fact material to the opinion hereinafter expressed,
we have relied without investigation upon the representations and warranties of
the Borrower and the Guarantors made in the Loan Documents. We have made no
examination or investigation to verify the accuracy or completeness of any
financial, accounting, or statistical information set forth in the Loan
Documents or otherwise furnished to you and, accordingly, express no opinion
with respect thereto.

         Insofar as our opinion expressed below relates to the matters set forth
in the above-mentioned opinion letter, we have assumed without independent
investigation the correctness of the matters set forth in such opinion, and our
opinion is subject to the assumptions, qualifications and limitations set forth
in such opinion letter.

C.       OPINION

         Based upon our examination and review as set forth in Section A hereof,
and subject to the assumptions, exceptions, qualifications, and limitations set
forth in Sections B and D hereof, we are of the opinion that the Credit
Agreement and each of the Notes constitute valid and binding obligations of the
Borrower enforceable against the Borrower in accordance with their respective
terms, and that the Guaranty constitutes valid and binding obligations of each
of the Guarantors enforceable against each of the Guarantors in accordance with
its terms.

D.       QUALIFICATIONS AND EXCEPTIONS

         The opinion rendered above is subject in all respects to the following
qualifications and comments:

         1.       Our opinion above, as to enforceability, is subject to the
                  effect of any applicable bankruptcy, insolvency, fraudulent
                  conveyance, reorganization, moratorium and other similar laws
                  relating to or affecting creditors' rights generally.

         2.       Our opinion is subject to the effect of general principles of
                  equity (whether considered in a proceeding in equity or at
                  law). In rendering our opinion, we have assumed that the
                  parties to the Loan Documents will perform their obligations
                  and exercise their rights under such documents within the
                  standards of reasonableness, good faith and fair dealing
                  imposed by applicable law.

         3.       We express no opinion with respect to the legality, validity,
                  binding nature, or enforceability of any of the following
                  provisions found in the Loan Documents, if any: (i) provisions
                  relating to waivers, precluding a party from asserting certain
                  claims or defenses or from obtaining or exercising certain
                  rights, releases, and remedies, or excusing

                  a party from damages, liability, or obligations to the extent
                  such provisions may violate public policy or otherwise violate
                  applicable law; (ii) provisions relating to subrogation
                  rights, delay or omission of enforcement of rights or
                  remedies, severability, or set offs that violate applicable
                  law; (iii) provisions obligating a party to submit to the
                  jurisdiction or venue of any court; (iv) provisions purporting
                  to establish evidentiary standards for suits or proceedings to
                  enforce the Loan Documents; (v) provisions that decisions by a
                  party are conclusive; and (vi) provisions purporting to effect
                  the automatic service of process on any person.

         4.       We are members of the bar of the States of New York and Texas
                  and we express no opinion as to the laws of any jurisdiction
                  other than the laws of the States of New York and Texas, the
                  General Corporate Law of the State of Delaware and the Federal
                  laws of the United States of America.

         5.       This opinion letter is limited to the matters stated herein
                  and no opinions may be implied or inferred beyond the matters
                  expressly stated herein.

         6.       The opinion expressed herein is as of the date hereof, and we
                  assume no obligation to update or supplement such opinion to
                  reflect any facts or circumstances that may hereafter come to
                  our attention or any changes in law that may hereafter occur.

         7.       This opinion is being furnished only to the addresses named
                  above, and has been rendered solely for your benefit in

                  relied upon or otherwise referred to for any other purpose
                  without our prior written consent; provided, however, that any
                  Person that becomes a Lender or successor Administrative Agent
                  pursuant to the terms of the Credit Agreement may rely on this
                  opinion as if it were addressed to such Person and delivered
                  on the date hereof.

                           FORM OF OPINION OF COUNSEL

February __, 2001

To each of the Lenders parties to the Credit
Agreement referred to below, and
Bank of America, N.A., as
Administrative Agent for the Lenders

Ladies and Gentlemen:

         I am General Counsel of The Williams Companies, Inc. and have acted as
counsel to (i) Williams OLP, L.P. (the "Borrower"), (ii) Williams Natural Gas
Liquids LLC ("WNGL"), Williams Terminals Holding L.P. ("WTH"), Williams
Pipelines Holdings L.P. ("WPH") and Williams Ammonia Pipeline L.P. ("WAP",
together with WNGL, WTH and WPH, the "Guarantors"), and (iii) Williams GP, LLC
(the "General Partner," and together with the Borrower and the Guarantors, the
"Transaction Parties") in connection with the Credit Agreement dated as of
February 6, 2001, by and among the Borrower, the Lenders party thereto, Bank of
America, N.A., as Administrative Agent for the Lenders, Lehman Commercial Paper,
Inc., as Syndication Agent, and SunTrust Bank, as Documentation Agent (the
"Agreement"). This opinion is furnished to you at the request of the Borrower
pursuant to Section 4.01(a)(vi) of the Agreement. Terms defined in the Agreement
not otherwise defined herein are used herein as therein defined.

         In connection with the opinions expressed herein, I, or attorneys
reporting to me, have examined and relied upon copies of the following
documents:

         (a)      the Agreement, including all exhibits, schedules, and
                  attachments thereto, and any Notes issued pursuant thereto
                  (the "Notes");

         (b)      the Guaranty dated as of even date with the Agreement executed
                  by each of the Guarantors (the "Guaranty");

         (c)      Certificates of the Secretary of State of the State of
                  Delaware dated February ___, 2001, attesting to the continued
                  existence and good standing of the Transaction Parties in
                  Delaware; and

         (d)      the Organization Documents of the Transaction Parties and all
                  amendments thereto.

         Those documents identified in items (a) and (b) above are collectively
referred to herein as the "Credit Documents." In connection with this opinion, I
or other attorneys acting under my supervision have (i) investigated such
questions of law, (ii) examined such partnership and company documents and
records of the Transaction Parties and certificates of public officials, and
(iii) received such information from officers and representatives of the
Transaction Parties and made such investigations as I or other attorneys under
my supervision have deemed necessary or appropriate for the purposes of this
opinion. I have not, nor have other attorneys under my supervision, conducted
independent investigations or inquiries to determine the existence of matters,
actions, proceedings, items, documents, facts, judgments, decrees,

                                  Exhibit F-2
                                     Page 1
                           Form of Opinion of Counsel

franchises, certificates, permits, or the like and have made no independent
search of the records of any court, arbitrator, or governmental authority
affecting any Person, and no inference as to my knowledge thereof shall be drawn
from the fact of my representation of any party or otherwise.

         In rendering the opinions herein, I have assumed without independent
verification (i) the genuineness of all signatures of the Lenders and the
Administrative Agent, (ii) the capacity of the signing officers of each of the
Lenders and the Administrative Agent, (iii) the authenticity of all documents
submitted to me as original and the conformity with the authentic originals of
all documents submitted to me as copies, and (iv) the due execution and
delivery, pursuant to due authorization, of the Agreement by the Lenders and the
Administrative Agent and the enforceability of the Agreement against the Lenders
and the Administrative Agent.

         Based upon and subject to the foregoing and the other qualifications,
limitations, and assumptions set forth below and upon such other matters as I
have deemed appropriate, I am of the opinion that:

         1.       The Borrower is a limited partnership duly organized, validly
                  existing, and in good standing under the laws of the State of
                  Delaware; WNGL is a limited liability company duly organized,
                  validly existing, and in good standing under the laws of the
                  State of Delaware; and each of WTH, WPH and WAP is a limited
                  partnership duly organized, validly existing, and in good
                  standing under the laws of the State of Delaware.

         2.       Each Transaction Party has the partnership or company power
                  and authority to own and lease its property and to conduct the
                  business in which it is currently engaged. The execution,
                  delivery, and performance by each of the Transaction Parties
                  of the Credit Documents and the consummation of the
                  transactions contemplated by the Credit Documents are (a)
                  within its partnership or company powers, (b) will not
                  contravene (i) the Organization Documents of any Transaction
                  Party, (ii) any law, rule, or regulation applicable to any
                  Transaction Party (including, without limitation, Regulation X
                  of the Board of Governors of the Federal Reserve System), or
                  (iii) any contractual or legal restriction, and (c) will not
                  result in or require the creation or imposition of any Lien
                  prohibited by the Credit Documents.

         3.       The Agreement has been duly authorized, executed, and
                  delivered to the Administrative Agent by the Borrower, and the
                  Guaranty has been duly authorized, executed, and delivered to
                  the Administrative Agent by each of the Guarantors.

         4.       No authorization, approval, or other action by, and no notice
                  to or filing with, any governmental authority or regulatory
                  body is required for the due execution, delivery, and
                  performance by any Transaction Party of the Credit Documents
                  to which it is a party or the consummation of the transactions
                  contemplated by the Credit Documents, except, in the case of
                  such performance, for such authorizations, approvals, actions,
                  notices, and filings which have been made or obtained.

         5.       To my knowledge there are no pending or overtly threatened
                  actions or proceedings against any Transaction Party before
                  any court, governmental agency, or arbitrator that purport to
                  affect the legality, validity, binding effect, or
                  enforceability of the Credit Documents, or that would
                  reasonably be expected to have a materially adverse effect
                  upon the financial condition or operations of any Transaction
                  Party, taken as a whole.

                                  Exhibit F-2

                           Form of Opinion of Counsel

<PAGE>

         6.       No Transaction Party is an "investment company" or a company
                  "controlled" by an "investment company" within the meaning of
                  the Investment Company Act of 1940, as amended. No Transaction
                  Party is a "holding company," or a "subsidiary company" of a
                  "holding company," or an "affiliate" of a "holding company" or
                  of a "subsidiary company" of a "holding company," or a "public
                  utility" within the meaning of the Public Utility Holding
                  Company Act of 1935, as amended.

         7.       In any action or proceeding arising out of or relating to the
                  Credit Documents in any court of the State of Oklahoma or in
                  any Federal court sitting in the State of Oklahoma, assuming
                  (i) proper venue, jurisdiction, and a full and proper
                  presentation of the issues and the law to the court, (ii) such
                  action or proceeding is not dismissed on the basis of an
                  inconvenient forum, and (iii) that the court properly applies
                  Oklahoma law, such court would (a) recognize and give effect
                  to the provisions of the Credit Documents that set forth the
                  governing law, and (b) construe the Credit Documents in
                  accordance with the internal laws of the State of New York.
                  Subject to the foregoing and without limiting the generality
                  thereof, a court of the State of Oklahoma or a Federal court
                  sitting in the State of Oklahoma would apply the usury law of
                  the State of New York, and would not apply the usury law of
                  the State of Oklahoma, to the Credit Documents. However, if a
                  court were to hold that the Credit Documents are governed by
                  or are to be construed in accordance with the laws of the
                  State of Oklahoma, the Agreement, when executed and delivered
                  by the parties thereto, would be, under the laws of the State
                  of Oklahoma, legal, valid, and binding obligations of the
                  Borrower, enforceable against the Borrower in accordance with
                  its terms, and the Guaranty would be, under the laws of the
                  State of Oklahoma, legal, valid and binding obligations of
                  each Guarantor, enforceable against each Guarantor in
                  accordance with its terms.

         The opinions expressed in this letter are subject to the following
additional qualifications and limitations:

         A.       My opinion in paragraph 1 with respect to the organization and
                  good standing of the Borrower, WNGL, WTH, WPH and WAP is based
                  solely on Certificates, dated as of February ___, 2001, from
                  the Secretary of State of the State of Delaware, certifying as
                  to such matters.

         B.       My opinion in the last sentence of paragraph 7 above is
                  subject, insofar as enforceability is concerned, to the effect
                  of any applicable bankruptcy, insolvency, reorganization,
                  fraudulent conveyance, moratorium, or similar law affecting
                  creditors' rights and remedies generally.

         C.       My opinion in the last sentence of paragraph 7 above is
                  subject, insofar as enforceability is concerned, to the effect
                  of general principles of equity including principles of
                  commercial reasonableness, good faith, and fair dealing
                  (regardless of whether considered in a proceeding in equity or
                  at law).

         D.       I express no opinion with respect to the enforceability of any
                  of the following: (i) indemnification provisions to the extent
                  the same are violative of federal or state securities laws,
                  rules, or regulations, or of public policy, (ii) clauses
                  waiving right to trial by jury,

                                  Exhibit F-2

                           Form of Opinion of Counsel
<PAGE>

                  exculpation clauses, or clauses granting offset rights to the
                  Banks or against any deposits or in respect of matured claims,
                  (iii) clauses relating to recovery of attorneys' fees in
                  connection with the enforcement of obligations, (iv) clauses
                  relating to release of unmatured claims and integration
                  clauses to the effect that no representation was made other
                  than as appears in the Agreement, (v) clauses purporting to
                  waive unmatured rights, representations, warranties, or
                  affirmative or negative covenants to the extent such
                  representations, warranties, or covenants can be construed to
                  be independent clauses which purport to be legal, valid,
                  binding, and enforceable by themselves, as distinguished from
                  being clauses that trigger an event of default, and
                  severability and similar clauses, and (vi) clauses that
                  incorporate by reference a document or instrument or agreement
                  not in existence on the date hereof to the extent that any
                  such document, instrument, or agreement is the basis of an
                  effort to enforce the Agreement, insofar as any of the
                  foregoing are contained in the Agreement.

         E.       I express no opinion as to the effect on the opinions herein
                  stated of compliance or non-compliance by any Lender with any
                  applicable state, federal, or other laws or regulations
                  applying only to banks, or the legal or regulatory status of
                  any Lender.

         F.       My opinion in paragraph 7 above assumes (i) application of New
                  York law would not be found to be contrary to a fundamental
                  policy of a state with a materially greater interest in
                  determining the question presented and the laws of which would
                  govern in absence of an effective choice of law, and (ii) the
                  Syndication Agent, one of the Joint Lead Arrangers and Joint
                  Book Managers, and one or more Lenders, each have their
                  principal place of business located in the State of New York,
                  and one or more Lenders has a place of business located in the
                  State of New York.

         G.       Qualification of any statement or opinion herein by the use of
                  the words "to my knowledge" means that during the course of
                  representation in connection with the transactions
                  contemplated by the Agreement, no information has come to the
                  attention of me or attorneys reporting to me that would give
                  me or such attorneys current actual knowledge of the existence
                  of facts or matters so qualified. I have not undertaken any
                  investigation to determine the existence of facts, and no
                  inference as to my knowledge thereof shall be drawn from the
                  fact of the representation by me or attorneys reporting to me
                  of any party or otherwise.

         I am admitted to practice law in the States of Oklahoma and New York,
and, accordingly, the opinions expressed herein are based upon and limited
exclusively to the laws of the States of Oklahoma and New York, the General
Corporation Law of the State of Delaware and the laws of the United States of
America insofar as any of such laws are applicable. I render no opinion with
respect to any other laws.

         This opinion letter is solely for the benefit of the Lenders and the
Administrative Agent, their respective successors, assigns, participants, and
other transferees and counsel for the Persons referred to in this sentence, in
consummating the transaction contemplated by the Credit Documents, and may not
be used or relied upon by, quoted, transmitted to, or filed with any other
Person or for any other purpose whatsoever without in each instance my prior
written consent. This opinion speaks as of its date, and I undertake no, and
hereby expressly disclaim any, duty to advise you as to any changes of fact or
law coming to my attention after the date hereof.

                                      Very truly yours,

                                      William G. von Glahn

                                 PROMISSORY NOTE
                                                           _______________, 2000

         WILLIAMS OLP, L.P. (the "BORROWER") promises to pay to the order of
________________ ("HOLDER"), upon the earlier of demand (provided, however, that
no demand may be made prior to Permitted Demand Date) or the Stated Termination
Date, the aggregate unpaid principal amount of Advances made by Holder to the
Borrower hereunder, in immediately available funds at the main office of Holder,
together with interest on the unpaid principal amount hereof at the rate set
forth herein. Capitalized terms used herein and not otherwise defined shall have
the meaning set forth in Exhibit A attached hereto and made a part of this
Promissory Note.

         Holder shall, and is hereby authorized to, record on the schedule
attached hereto, or to otherwise record, the date and amount of each Advance and
the date and amount of each principal payment hereunder and such recording shall
be conclusive and binding for all purposes, absent manifest error; provided
however, that the failure to so record shall not affect the Borrower's
obligations under this Promissory Note.

         Interest shall be computed on the basis of a year of 360 days for the
actual number of days elapsed at the Eurodollar Rate per annum plus the
Applicable Margin in effect from time to time. The interest rate will be a fixed
rate for the entire calendar month commencing on the first calendar day of the
month and ending on the last calendar day of the month. The Borrower shall pay
interest on the unpaid principal amount monthly on the 25th date of each month,
and on the date of payment in full.

         Any amount of principal not paid when due shall bear interest, from the
date on which such amount is due until such amount is paid in full, at a rate
per annum equal to the sum of the rate per annum required to be paid on the
Advance plus 2% per annum.

         No failure to exercise, and no delay in exercising any rights hereunder
on the part of the holders hereof shall operate as a waiver of such rights.

         The undersigned agrees to pay all costs, including reasonable
attorney's fees, incurred by the holder in enforcing payment hereof.

         The Borrower agrees, and Holder as holder of this Promissory Note and
by acceptance of this Promissory Note agrees, that the payment of any principal,
interest or penalty under this Promissory Note is expressly subordinated to the
Senior Debt for the benefit of the Administrative Agent and the Lenders, as
follows:

         1. Subordination of Payment. After such time as a Default or Event of
Default (as defined in the OLP Credit Agreement) has occurred and is continuing,
Holder will not ask for, demand, sue for, take, receive or accept from the
Borrower, by setoff or in any other manner, any payment or distribution on
account of the obligations evidenced by this Promissory Note, nor present this
Promissory Note for payment.

         2. No Payments in Violation of Senior Debt Documents. Holder will not
ask for, demand, sue for, take, receive or accept from the Borrower, by setoff
or in any other manner, any payment or distribution on account of the debt
evidenced by this Promissory Note, if the making of such payment

                                   Exhibit G
                                     Page 1
                             Form of Promissory Note
<PAGE>

would constitute, or would result in the occurrence of, a violation of the OLP
Credit Agreement, or would result in the occurrence of any Default or Event of
Default thereunder.

         3. Bankruptcy, Receivership and Similar Proceedings.

                  (a) Upon any payment or distribution of all or any of the
assets or securities of the Borrower of any kind or character, whether in cash,
property or securities, upon dissolution, winding up, liquidation,
reorganization, arrangement, adjustment, protection or relief of the Borrower or
its debts whether voluntary or involuntary or in bankruptcy, insolvency,
receivership, arrangement, reorganization, relief or other proceedings (an
"INSOLVENCY PROCEEDING") or upon an arrangement for the benefit of creditors or
any other marshalling of the assets and liabilities of the Borrower or
otherwise, all Senior Debt shall first be paid in full in cash before the Holder
shall be entitled to receive any payment of the obligations evidenced by this
Promissory Note. Upon any of the circumstances referred to in the preceding
sentence, any payment or distribution of assets or securities of the Borrower of
any kind or character, whether in cash, property or securities, to which Holder
would be entitled except for the provisions of Sections 1 through 6 of this
Promissory Note, shall be made by the Borrower or any receiver, trustee in
bankruptcy, liquidating trustee, agent or other person making such payment or
distribution, directly to the Administrative Agent for the benefit of the
Lenders for application to the payment or prepayment of all Senior Debt in full.

                  (b) In the event of any Insolvency Proceeding, whether or not
pursuant to bankruptcy laws, Holder will at the Administrative Agent's request
file any claim, proof of claim, proof of interest or other instrument of similar
character necessary to enforce the obligations of the Borrower in respect to the
debt evidenced by this Promissory Note and will hold all payments on and
proceeds from such debt evidenced by this Promissory Note in trust for the
Administrative Agent and the Lenders and pay the same over to the Administrative
Agent in the form received (together with any necessary endorsement), to be
applied on the Senior Debt remaining unpaid until all Senior Debt shall be paid
in full. In the event that Holder shall fail to take any such action requested
by the Administrative Agent, the Administrative Agent may, as attorney-in-fact
for Holder, take such action on behalf of Holder and Holder hereby appoints the
Administrative Agent as attorney-in-fact for Holder to demand, sue for, collect
and receive any and all such monies, dividends or other assets and give
acquittance therefor and to file any claim, proof of claim, proof of interest or
other instrument of similar character and take such other proceeding in the
Administrative Agent's own name or in the name of Holder as the Administrative
Agent may deem necessary or advisable for the enforcement of these subordination
provisions; this appointment is irrevocable and is coupled with an interest in
such monies, dividends and assets. Holder will execute and deliver to the
Administrative Agent such other and further powers of attorney or other
instruments as the Administrative Agent may request in order to accomplish the
foregoing.

         4. Payments Held in Trust. In the event Holder shall receive any
payment or distribution on account of the debt evidenced by this Promissory Note
which Holder is prohibited from receiving under the provisions of the foregoing
paragraphs 1, 2 or 3, Holder will hold any amount so received in trust for the
Administrative Agent and the Lenders and will forthwith turn over such payment
to the Administrative Agent in the form received by Holder (together with any
necessary endorsement) to be applied on the Senior Debt remaining unpaid until
all Senior Debt has been paid in full, after giving effect to any concurrent
payment or distribution to the Administrative Agent.

         5. Restrictions on Action Against Borrower. Holder will not commence
any action or proceeding against the Borrower to recover all or any part of the
debt evidenced by this Promissory Note, nor join with any other creditor, unless
the Administrative Agent shall also join, in bringing any proceedings against
the Borrower under any bankruptcy, reorganization, readjustment of debt,
arrangement

                                   Exhibit G
                                     Page 2

of debt, receivership, liquidation or insolvency law, or statute of the federal
or any state government, unless and until all Senior Debt shall have been paid
in full and all commitments to lend under the OLP Credit Agreement have
terminated.

         6. Miscellaneous.

                  (a) All rights and interests of Lenders and the Administrative
Agent under Sections 1 through 6 of this Promissory Note, and all agreements and
obligations of the Holder and the Borrower under such Sections, shall remain in
full force and effect irrespective of: (i) any lack of validity or
enforceability of the OLP Credit Agreement or the other OLP Loan Documents; (ii)
any change in the time, manner or place of payment of, or in any other term of,
all or any of the Senior Debt, or any other amendment or waiver of or any
consent to departure from the OLP Credit Agreement or the other OLP Loan
Documents; (iii) any exchange, release or non-perfection of any collateral, or
any release or amendment or waiver of or consent to departure from any guaranty,
for all or any of the Senior Debt; or (iv) any other circumstance that might
otherwise constitute a defense available to, or a discharge of, the Borrower or
a subordinated creditor.

                  (b) The provisions of these Sections 1 through 6 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 Administrative Agent or any Lender upon the insolvency, bankruptcy or
reorganization of the Borrower or otherwise, all as though such payment had not
been made.

                  (c) No failure on the part of the Administrative Agent or any
Lender to exercise, and no delay in exercising, any right hereunder shall
operate as a waiver thereof; nor shall any single or partial exercise of any
right hereunder preclude any other or further exercise thereof or the exercise
of any other right. The remedies herein provided are cumulative and not
exclusive of any remedies provided by law.

                  (d) The provisions of these Sections 1 through 6 shall (i)
remain in full force and effect until the Senior Debt shall have been paid in
full and all commitments to lend under the OLP Credit Agreement have terminated,
(ii) be binding upon the Holder, the Borrower and their successors and assigns,
and (iii) inure to the benefit of and be enforceable by the Administrative Agent
and the Lenders and their successors, transferees and assigns.

         This Promissory Note shall be governed by and construed in accordance
with the laws of the State of Oklahoma and reflects an uncommitted credit
arrangement between the Borrower and Holder.

("GUARANTORS"), BANK OF AMERICA, N.A., as Administrative Agent (the
"ADMINISTRATIVE AGENT") for the Lenders under the Credit Agreement hereinafter
referenced, and the Lenders (as defined in the Credit Agreement) party hereto.

         Reference is made to the Credit Agreement dated as of February 6, 2001
(the "CREDIT AGREEMENT") among Borrower, Administrative Agent, Lehman Commercial
Paper, Inc., as Syndication Agent, SunTrust Bank as Documentation Agent, and the
Lenders party thereto. Unless otherwise defined in this Amendment, capitalized
terms used herein shall have the meaning set forth in the Credit Agreement; all
Section and Schedule references herein are to Sections and Schedules in the
Credit Agreement; and all Paragraph references herein are to Paragraphs in this
Amendment.

                                    RECITALS

         A. Borrower has advised the Administrative Agent and the Lenders that
as of March 31, 2001, the Interest Coverage Ratio was 2.3 to 1.0, which is lower
than the 3.0 Interest Coverage Ratio required by SECTION 7.14(a) of the Credit
Agreement. Borrower has advised that this is the result of including, in such
calculation, interest expense with respect to approximately $225,000,000 of
intercompany debt that was repaid with proceeds of the MLP Offering. Therefore,
Borrower has requested that the Administrative Agent and the Lenders agree to
waive such Interest Coverage Ratio default, and to amend the definition of
Interest Coverage Ratio. Borrower also has requested amendments to the Credit
Agreement to allocate a portion of the Revolver Commitment from the Working
Capital/Distribution Subfacility to the Acquisition Subfacility so that the
Acquisition Subfacility Commitment equals $48,000,000 and the Working
Capital/Distribution Subfacility Commitment equals $12,000,000. In addition to
this First Amendment, Borrower also has requested that the Administrative Agent
and the Lenders enter into a Second Amendment to Credit Agreement to increase
the Revolver Commitment from $60,000,000 to an amount up to $85,000,000 by
increasing the Acquisition Subfacility from $48,000,000 to an amount up to
$73,000,000.

         B. Subject to the terms and conditions of this Amendment, the
Administrative Agent and the undersigned Lenders are willing to agree to such
amendments.

         Accordingly, for adequate and sufficient consideration, the parties
hereto agree, as follows:

         PARAGRAPH 1. LIMITED WAIVER. The undersigned Administrative Agent and
Lenders hereby waive the Event of Default under SECTION 7.14(a) of the Credit
Agreement resulting from the Interest Coverage Ratio being less than 3.0 to 1.0
as of the fiscal quarter ending March 31, 2001. Nothing herein shall, or shall
be deemed to, waive the provisions of SECTION 7.14(a) or any other provisions of
the Credit Agreement, except as expressly set forth above with respect to the
Interest Coverage Ratio as of March 31, 2001.

         9.1 Order of Completion of Transactions; Effective Time.

               (a) The transactions provided for in Articles I, II, III and IV
     of this Agreement shall be completed on the date of this Agreement in the
     following order:

               First, the transactions provided for in Article II shall be
     completed;

                                       18
<PAGE>

               Second, the transactions provided for in Article IV shall be
     completed; and

               Third, the transactions provided for in Article III shall be
     completed.

               (b) The contribution of the Excluded Assets to WBE LLC shall be
     effective for all purposes as of the Effective Time.

         9.2 Consents; Restriction on Assignment. If there are prohibitions
against or conditions to the contribution and conveyance of one or more portions
of the Excluded Assets without the prior written consent of third parties,
including, without limitation, governmental agencies (other than consents of a
ministerial nature which are normally granted in the ordinary course of
business), which if not satisfied would result in a breach of such prohibitions
or conditions or would give an outside party the right to terminate WBE LLC's
rights with respect to such portion of the Excluded Assets (herein called a
"Restriction"), then any provision contained in this Agreement to the contrary
notwithstanding, the transfer of title to or interest in each such portion of
the Excluded Assets (herein called the "Restriction-Asset") pursuant to this
Agreement shall not become effective unless and until such Restriction is
satisfied, waived or no longer applies. When and if such a Restriction is so
satisfied, waived or no longer applies, to the extent permitted by applicable
law and any applicable contractual provisions, the assignment of the
Restriction-Asset subject thereto shall become effective automatically as of the
Effective Time, without further action on the part of WBE LLC or either of the
Terminals LP. Terminals LP and WBE LLC agree to use their reasonable best
efforts to obtain satisfaction of any Restriction on a timely basis. The
description of any portion of the Excluded Assets as a "Restriction-Asset" shall
not be construed as an admission that any Restriction exists with respect to the
transfer of such portion of the Excluded Assets. In the event that any
Restriction-Asset exists, Terminals LP agrees to hold such Restriction-Asset in
trust for the exclusive benefit of WBE LLC and to otherwise use its reasonable
best efforts to provide WBE LLC with the benefits thereof, and Terminals LP will
enter into other agreements, or take such other action as it may deem necessary,
in order to help ensure that WBE LLC has the assets and concomitant rights
necessary to enable it to operate the Excluded Assets contributed to WBE LLC in
all material respects as they were operated prior to the Effective Time.

         9.3 Costs. WBE LLC shall pay all sales, use and similar taxes arising
out of the contributions, conveyances and deliveries to be made hereunder, and
shall pay all documentary, filing, recording, transfer, deed, and conveyance
taxes and fees required in connection therewith. In addition, WBE LLC shall be
responsible for all costs, liabilities and expenses (including court costs and
reasonable attorneys' fees) incurred in connection with the satisfaction or
waiver of any Restriction pursuant to Section 9.2.

         9.4 Headings; References; Interpretation. All Article and Section

The words "hereof," "herein" and "hereunder" and words of similar import, when
used in this Agreement, shall refer to this Agreement as a whole, including
without limitation, all Exhibits attached hereto, and not to any particular
provision of this Agreement. All references herein to Articles, Sections, and
Exhibits shall, unless the context requires a different construction, be deemed
to be references to the Articles, Sections and Exhibits of this Agreement,

general statement, term or matter shall not be construed to limit such
statement, term or matter to the specific items or matters set forth immediately
following such word or to similar items or matters, whether or not non-limiting
language (such as "without limitation," "but not limited to," or words of
similar import) is used with reference thereto, but rather shall be deemed to
refer to all other items or matters that could reasonably fall within the
broadest possible scope of such general statement, term or matter.

inure to the benefit of the parties signatory hereto and their respective
successors and assigns.

intended to bind the parties signatory hereto as to each other and are not
intended to and do not create rights in any other person or confer upon any
other person any benefits, rights or remedies and no person is or is intended to
be a third party beneficiary of any of the provisions of this Agreement.

made and to be performed wholly within such state without giving effect to
conflict of law principles thereof, except to the extent that it is mandatory
that the law of some other jurisdiction, wherein the Excluded Assets are
located, shall apply.

         9.9 Severability. If any of the provisions of this Agreement are held
by any court of competent jurisdiction to contravene, or to be invalid under,
the laws of any political body having jurisdiction over the subject matter
hereof, such contravention or invalidity shall not invalidate the entire
Agreement. Instead, this Agreement shall be construed as if it did not contain
the particular provision or provisions held to be invalid, and an equitable
adjustment shall be made and necessary provision added so as to give effect to
the intention of the parties as expressed in this Agreement at the time of
execution of this Agreement.

modified from time to time only by the written agreement of all the parties
hereto.

subject matter. This document is an integrated agreement which contains the
entire understanding of the parties. No understanding, representation, promise
or agreement, whether oral or written, is intended to be or shall be included in
or form part of this Agreement unless it is contained in a written amendment
hereto executed by the parties hereto after the date of this Agreement.
