Notice of Borrowing for such Borrowing the applicable conditions set forth in
Article III, including, without limitation, any loss (excluding loss of
anticipated profits), cost or expense incurred by reason of the liquidation or
reemployment of deposits or other funds acquired by such Lender to fund the
Reimbursement Advance to be made by such Lender as part of such Borrowing when
such Reimbursement Advance, as a result of such failure, is not made on such
date.

     (d) Unless the Agent shall have received notice from a Lender prior to the
time of any Borrowing that such Lender will not make available to the Agent such
Lender's ratable portion of such Borrowing, the Agent may assume that such
Lender has made such portion available to the Agent on the date of such
Borrowing in accordance with subsection (a) of this Section 2.02

                                       14

<PAGE>

and the Agent may, in reliance upon such assumption, make available to the
Borrower on such date a corresponding amount. If and to the extent that such
Lender shall not have so made such ratable portion available to the Agent, such
Lender and the Borrower severally agree to repay to the Agent forthwith on
demand such corresponding amount together with interest thereon, for each day
from the date such amount is made available to the Borrower until the date such
amount is repaid to the Agent, at (i) in the case of the Borrower, the interest
rate applicable at the time to Reimbursement Advances comprising such Borrowing
and (ii) in the case of such Lender, the Federal Funds Rate. If such Lender
shall repay to the Agent such corresponding amount, such amount so repaid shall
constitute such Lender's Reimbursement Advance as part of such Borrowing for
purposes of this Agreement.

     (e) The failure of any Lender to make the Reimbursement Advance to be made
by it as part of any Borrowing shall not relieve any other Lender of its
obligation, if any, hereunder to make its Reimbursement Advance on the date of
such Borrowing, but no Lender shall be responsible for the failure of any other
Lender to make the Reimbursement Advance to be made by such other Lender on the
date of any Borrowing.

          SECTION 2.03. Fees. (a) Commitment Fee. The Borrower agrees to pay to
the Agent for the account of each Lender (based on its Pro Rata Share), for the
period (including any portion thereof when any Commitment is suspended by reason
of the Borrower's inability to satisfy any condition of Article III) commencing
on the Effective Date and continuing through the Commitment Termination Date, a
commitment fee at a per annum rate equal to the then effective Applicable
Commitment Fee Rate, multiplied by the sum of the average daily unused portion
of the Commitment of such Lender. All commitment fees payable pursuant to this
Section shall be payable by the Borrower in arrears on the last day of each
March, June, September and December, and on the Commitment Termination Date. For
purposes of computing commitment fees, the Commitment of a Lender shall be
deemed to be used to the extent of the Outstanding Credit Exposure of such
Lender.

     (b) Agent's Fees. The Borrower shall pay to the Agent for its own account
such fees as may from time to time be agreed between the Borrower and the Agent.

     (c) LC Fees. The Borrower shall pay to the Agent, for the account of the
Lenders ratably in accordance with their respective Pro Rata Shares, a per annum
letter of credit fee equal to the Applicable LC Fee Rate multiplied by the
average daily undrawn stated amount under such Facility LC, such fee to be
payable in arrears quarterly on the last day of each March, June, September and
December, and on the Commitment Termination Date (each such fee described in
this sentence an "LC Fee"). The Borrower shall also pay to the LC Issuer for its
own account (x) a fronting fee in an amount and payable at such times as is
agreed upon between the LC Issuer and the Borrower, and (y) documentary and
processing charges in connection with the issuance or Modification of and draws
under Facility LCs in accordance with the LC Issuer's standard schedule for such
charges as in effect from time to time.

          SECTION 2.04. Termination or Reduction of the Commitments. (a) The
Commitments shall be automatically terminated on the Commitment Termination
Date.

                                       15

<PAGE>

     (b) The Borrower shall have the right, upon at least three Business Days'
notice to the Agent, to terminate in whole or reduce ratably in part the unused
portions of the respective Commitments of the Lenders, provided that each
partial reduction shall be in the aggregate amount of $5,000,000 or an integral
multiple of $1,000,000 in excess thereof. Once terminated, a Commitment or
portion thereof may not be reinstated.

          SECTION 2.05. Repayment of Credit Extensions. The Borrower shall repay
to the Agent for the ratable account of the Lenders on the Commitment
Termination Date (or, if the Aggregate Outstanding Credit Exposures have been
converted to a term loan as set forth in Section 2.19, on the Facility
Termination Date) any Aggregate Outstanding Credit Exposures and all other
unpaid Obligations. In addition, the Borrower shall make all payments required
to be made under Section 2.18 to each Lender that does not consent to an
extension of the Commitment Termination Date.

          SECTION 2.06. Interest on Reimbursement Advances. (a) Scheduled
Interest. The Borrower shall pay interest on the unpaid principal amount of each
Reimbursement Advance owing to each Lender from the date of such Reimbursement
Advance until such principal amount shall be paid in full, at the following
rates per annum:

          (i) Base Rate Advances. During such periods as such Reimbursement
     Advance is a Base Rate Advance, a rate per annum equal at all times to the
     sum of (x) the Base Rate in effect from time to time plus (y) the
     Applicable Margin in effect from time to time, payable in arrears quarterly
     on the last day of each March, June, September and December during such
     periods and on the date such Base Rate Advance shall be Converted or paid
     in full.

          (ii) Eurodollar Rate Advances. During such periods as such
     Reimbursement Advance is a Eurodollar Rate Advance, a rate per annum equal
     at all times during each Interest Period for such Reimbursement Advance to
     the sum of (x) the Eurodollar Rate for such Interest Period for such
     Reimbursement Advance plus (y) the Applicable Margin in effect from time to
     time, payable in arrears on the last day of such Interest Period and, if
     such Interest Period has a duration of more than three months, on each day
     that occurs during such Interest Period every three months from the first
     day of such Interest Period and on the date such Eurodollar Rate Advance
     shall be Converted or paid in full.

     (b) Default Interest. (i) Upon the occurrence and during the continuance of
an Event of Default, (x) the Borrower shall pay interest on the unpaid principal
amount of each Reimbursement Advance owing to each Lender, payable in arrears on
the dates referred to in clause (a)(i) or (a)(ii) above, at a rate per annum
equal at all times to 2% per annum above the rate per annum required to be paid
on such Reimbursement Advance pursuant to clause (a)(i) or (a)(ii) above and (y)
the LC Fee shall be increased by 2% per annum, and (ii) the Borrower shall pay,
to the fullest extent permitted by law, the amount of any interest, fee or other
amount payable hereunder that is not paid when due, from the date such amount
shall be due until such amount shall be paid in full, payable in arrears on the
date such amount shall be paid in full and on demand, at a rate per annum equal
at all times to 2% per annum above the rate per annum required to be paid on
Base Rate Advances pursuant to clause (a)(i) above.

                                       16

<PAGE>

          SECTION 2.07. Interest Rate Determination. (a) The Reference Bank
agrees to furnish to the Agent timely information for the purpose of determining
each Eurodollar Rate. The Agent shall give prompt notice to the Borrower and the
Lenders of the applicable interest rate determined by the Agent for purposes of
Section 2.06(a)(i) or (ii), and the rate, if any, furnished by the Reference
Bank for the purpose of determining the interest rate under Section 2.06(a)(ii).

     (b) If, with respect to any Eurodollar Rate Advances, the Required Lenders
notify the Agent that the Eurodollar Rate for any Interest Period for such
Eurodollar Rate Advances will not adequately reflect the cost to such Required
Lenders of making, funding or maintaining their respective Eurodollar Rate
Advances for such Interest Period, the Agent shall forthwith so notify the
Borrower and the Lenders, whereupon (i) each Eurodollar Rate Advance will
automatically, on the last day of the then existing Interest Period therefor,
Convert into a Base Rate Advance, and (ii) the obligation of the Lenders to
make, or to Convert Reimbursement Advances into, Eurodollar Rate Advances shall
be suspended until the Agent shall notify the Borrower and the Lenders that the
circumstances causing such suspension no longer exist.

     (c) If the Borrower shall fail to select the duration of any Interest
Period for any Eurodollar Rate Advances in accordance with the provisions
contained in the definition of "Interest Period" in Section 1.01, the Agent will
forthwith so notify the Borrower and the Lenders and such Eurodollar Rate
Advances will automatically, on the last day of the then existing Interest
Period therefor, Convert into Base Rate Advances.

     (d) On the date on which the aggregate unpaid principal amount of
Eurodollar Rate Advances comprising any Borrowing shall be reduced, by payment
or prepayment or otherwise, to less than $5,000,000, such Eurodollar Rate
Advances shall automatically Convert into Base Rate Advances.

     (e) Upon the occurrence and during the continuance of any Event of Default,
(i) each Eurodollar Rate Advance will automatically, on the last day of the then
existing Interest Period therefor, Convert into a Base Rate Advance and (ii) the
obligation of the Lenders to make, or to Convert Reimbursement Advances into,
Eurodollar Rate Advances shall be suspended.

     (f) If the Service is not available or a rate does not timely appear on the
Service and the Reference Bank does not furnish timely information to the Agent
for determining the Eurodollar Rate for any Eurodollar Rate Advances:

          (i) the Agent shall forthwith notify the Borrower and the Lenders that
     the interest rate cannot be determined for such Eurodollar Rate Advances,

          (ii) with respect to Eurodollar Rate Advances, each such Eurodollar
     Rate Advance will automatically, on the last day of the then existing
     Interest Period therefor, Convert into a Base Rate Advance (or if such
     Advance is then a Base Rate Advance, will continue as a Base Rate Advance),
     and

          (iii) the obligation of the Lenders to make Eurodollar Rate Advances
     or to Convert Reimbursement Advances into Eurodollar Rate Advances shall be
     suspended

                                       17

<PAGE>

     until the Agent shall notify the Borrower and the Lenders that the
     circumstances causing such suspension no longer exist.

          SECTION 2.08. Optional Conversion of Reimbursement Advances. The
Borrower may on any Business Day, upon notice given to the Agent not later than
11:00 A.M. (New York City time) on the third Business Day prior to the date of
the proposed Conversion and subject to the provisions of Sections 2.07 and 2.11,
Convert all Reimbursement Advances of one Type comprising the same Borrowing
into Reimbursement Advances of the other Type (it being understood that such
Conversion of a Reimbursement Advance or of its Interest Period does not
constitute a repayment or prepayment of such Reimbursement Advance); provided,
however, that any Conversion of Eurodollar Rate Advances into Base Rate Advances
shall be made only on the last day of an Interest Period for such Eurodollar
Rate Advances, any Conversion of Base Rate Advances into Eurodollar Rate
Advances shall be in an amount not less than the minimum amount specified in
Section 2.02(b) and no Conversion of any Reimbursement Advances shall result in
more separate Borrowings than permitted under Section 2.02(b). Each such notice
of a Conversion shall, within the restrictions specified above, specify (i) the
date of such Conversion, (ii) the Reimbursement Advances to be Converted, and
(iii) if such Conversion is into Eurodollar Rate Advances, the duration of the
initial Interest Period for each such Eurodollar Rate Advance. Each notice of
Conversion shall be irrevocable and binding on the Borrower.

          SECTION 2.09. Prepayments of Reimbursement Advances. (a) Optional
Prepayment. The Borrower may on any Business Day, upon notice given to the Agent
not later than 11:00 A.M. (New York City time), (i) on the same day for Base
Rate Advances and (ii) on the second Business Day prior to the prepayment in the
case of Eurodollar Rate Advances stating the proposed date and aggregate
principal amount of the prepayment (and if such notice is given the Borrower
shall) prepay the outstanding principal amount of the Reimbursement Advances
comprising part of the same Borrowing in whole or ratably in part, together with
accrued interest to the date of such prepayment on the principal amount prepaid;
provided, however, that (x) each partial prepayment shall be in an aggregate
principal amount of $5,000,000 or an integral multiple of $1,000,000 in excess
thereof and (y) in the event of any such prepayment of a Eurodollar Rate
Advance, the Borrower shall be obligated to reimburse the Lenders in respect
thereof pursuant to Section 8.04(c).

     (b) Mandatory Prepayment. The Borrower shall, upon five Business Days'
notice from the Agent given at the request or with the consent of the Required
Lenders, (i) pay to the Agent the Collateral Shortfall Amount at such time,
which funds shall be held in the Facility LC Collateral Account, and (ii) prepay
the Aggregate Outstanding Credit Exposures (other than the undrawn stated amount
under all Facility LCs outstanding at such time) plus all interest thereon and
all other amounts payable hereunder or under the Notes, in the event that any
Person or two or more Persons acting in concert shall have acquired beneficial
ownership (within the meaning of Rule 13d-3 of the Securities and Exchange
Commission under the Securities Exchange Act of 1934), directly or indirectly,
of Voting Stock of the Borrower (or other securities convertible into such
Voting Stock) representing 30% or more of the combined voting power of all
Voting Stock of the Borrower. If at any time subsequent to the foregoing payment
of the Collateral Shortfall Amount, the Agent determines that the Collateral
Shortfall Amount at such time is greater than zero, the Agent may make demand on
the Borrower to pay, and the Borrower will, forthwith upon such demand and
without any further notice or act, pay to the Agent the Collateral Shortfall

                                       18

<PAGE>

Amount at such time, which funds shall be deposited in the Facility LC
Collateral Account. The Agent may at any time or from time to time after funds
are deposited in the Facility LC Collateral Account, apply such funds to the
payment of the Obligations and any other amounts as shall from time to time have
become due and payable by the Borrower to the Lenders or the LC Issuer under the
Loan Documents. Neither the Borrower nor any Person claiming on behalf of or
through the Borrower shall have any right to withdraw any of the funds held in
the Facility LC Collateral Account pursuant to this Section 2.09(b); provided,
however, that after all of the Obligations have been indefeasibly paid in full
and the aggregate Commitments have been terminated, any funds remaining in the
Facility LC Collateral Account shall be returned by the Agent to the Borrower or
paid to whomever may be legally entitled thereto at such time.

          SECTION 2.10. Increased Costs. (a) If, due to either (i) the
introduction of or any change in or in the interpretation of any law or
regulation or (ii) the compliance with any guideline or request from any central
bank or other governmental authority (whether or not having the force of law),
there shall be any increase in the cost to any Lender of agreeing to make or
making, funding or maintaining Eurodollar Rate Advances or participating in any
Facility LC or to the LC Issuer of agreeing to issue any Facility LC hereunder
(excluding for purposes of this Section 2.10 any such increased costs resulting
from taxes (as to which Section 2.13 shall govern), then the Borrower shall from
time to time, upon demand by such Lender or the LC Issuer (with a copy of such
demand to the Agent), pay to the Agent for the account of such Lender or the LC
Issuer, as applicable, additional amounts sufficient to compensate such Lender
or the LC Issuer, as applicable, for such increased cost. A certificate as to
the amount of such increased cost, submitted to the Borrower and the Agent by
such Lender or the LC Issuer, as applicable, shall be conclusive and binding for
all purposes, absent manifest error.

     (b) If any Lender or the LC Issuer determines that compliance with any law
or regulation or any guideline or request from any central bank or other
governmental authority (whether or not having the force of law) affects or would
affect the amount of capital required or expected to be maintained by such
Lender or the LC Issuer or any corporation controlling such Lender or the LC
Issuer, as applicable, and that the amount of such capital is increased by or
based upon the existence of such Lender's commitment to lend hereunder or to
participate in Facility LCs hereunder and other commitments of this type or the
LC Issuer's issuance of Facility LCs hereunder, then, upon demand by such Lender
or the LC Issuer, as applicable, (with a copy of such demand to the Agent), the
Borrower shall pay to the Agent for the account of such Lender or the LC Issuer,
as applicable, from time to time as specified by such Lender or the LC Issuer,
as applicable, additional amounts sufficient to compensate such Lender or the LC
Issuer, as applicable, or such corporation in the light of such circumstances,
to the extent that such Lender or the LC Issuer, as applicable, reasonably
determines such increase in capital to be allocable to the existence of such
Lender's commitment to lend hereunder or to participate in Facility LCs
hereunder or the LC Issuer's agreement to issue Facility LCs hereunder. A
certificate as to such amounts submitted to the Borrower and the Agent by such
Lender or the LC Issuer, as applicable, shall be conclusive and binding for all
purposes, absent manifest error.

     (c) In the event that a Lender demands payment from the Borrower for
amounts owing pursuant to subsection (a) or (b) of this Section 2.10, the
Borrower may, upon payment of such amounts and subject to the requirements of
Sections 8.04 and 8.07, substitute for such Lender another financial
institution, which financial institution shall be an Eligible Assignee and

                                       19

<PAGE>

shall assume the Commitments of such Lender and purchase the Outstanding Credit
Exposures held by such Lender in accordance with Section 8.07, provided,
however, that (i) no Default shall have occurred and be continuing, (ii) the
Borrower shall have satisfied all of its obligations in connection with the Loan
Documents with respect to such Lender, and (iii) if such assignee is not a
Lender, (A) such assignee is acceptable to the Agent and (B) the Borrower shall
have paid the Agent a $3,000 administrative fee.

          SECTION 2.11. Illegality. Notwithstanding any other provision of this
Agreement, if any Lender shall notify the Agent that the introduction of or any
change in or in the interpretation of any law or regulation makes it unlawful,
or any central bank or other governmental authority asserts that it is unlawful,
for any Lender or its Eurodollar Lending Office to perform its obligations
hereunder to make Eurodollar Rate Advances or to fund or maintain Eurodollar
Rate Advances hereunder, (i) each Eurodollar Rate Advance will automatically,
upon such demand, Convert into a Base Rate Advance or a Reimbursement Advance
that bears interest at the rate set forth in Section 2.06(a)(i), as the case may
be, and (ii) the obligation of the Lenders to make Eurodollar Rate Advances or
to Convert Reimbursement Advances into Eurodollar Rate Advances shall be
suspended until the Agent shall notify the Borrower and the Lenders that the
circumstances causing such suspension no longer exist.

          SECTION 2.12. Payments and Computations. (a) The Borrower shall make
each payment hereunder and under the Notes not later than 11:00 A.M. (New York
City time) on the day when due in U.S. dollars to the Agent at the Agent's
Account in same day funds and without set off, deduction or counterclaim other
than deductions on account of taxes. The Agent will promptly thereafter cause to
be distributed like funds relating to the payment of principal or interest,
commitment fees or LC Fees ratably (other than amounts payable pursuant to
Section 2.10, 2.13 or 8.04(c)) to the Lenders and the LC Issuer, as applicable,
for the account of their respective Applicable Lending Offices, and like funds
relating to the payment of any other amount payable to any Lender or the LC
Issuer to such Lender or the LC Issuer for the account of its Applicable Lending
Office, in each case to be applied in accordance with the terms of this
Agreement. Upon its acceptance of an Assignment and Acceptance and recording of
the information contained therein in the Register pursuant to Section 8.07(c),
from and after the effective date specified in such Assignment and Acceptance,
the Agent shall make all payments hereunder and under the Notes in respect of
the interest assigned thereby to the Lender assignee thereunder, and the parties
to such Assignment and Acceptance shall make all appropriate adjustments in such
payments for periods prior to such effective date directly between themselves.

     (b) The Borrower hereby authorizes each Lender and the LC Issuer, if and to
the extent payment owed to such Lender or the LC Issuer is not made when due
hereunder or under the Note held by such Lender or the LC Issuer, to charge from
time to time against any or all of the Borrower's accounts with such Lender or
the LC Issuer any amount so due.

     (c) All computations of interest based on the Base Rate (other than such
computations of the Base Rate that are based on the Federal Funds Rate) shall be
made by the Agent on the basis of a year of 365 or 366 days, as the case may be,
and all computations of interest based on the Eurodollar Rate or the Federal
Funds Rate and of the commitment fees and

                                       20

<PAGE>

the LC Fee shall be made by the Agent on the basis of a year of 360 days, in
each case for the actual number of days (including the first day but excluding
the last day) occurring in the period for which such interest, commitment fees
or the LC Fee are payable. Each determination by the Agent of an interest rate
hereunder shall be conclusive and binding for all purposes, absent manifest
error.

     (d) Whenever any payment hereunder or under the Notes shall be stated to be
due on a day other than a Business Day, such payment shall be made on the next
succeeding Business Day, and such extension of time shall in such case be
included in the computation of payment of interest, commitment fee or the LC
Fee, as the case may be; provided, however, that, if such extension would cause
payment of interest on or principal of Eurodollar Rate Advances to be made in
the next following calendar month, such payment shall be made on the next
preceding Business Day.

     (e) Unless the Agent shall have received notice from the Borrower prior to
the date on which any payment is due to the Lenders or the LC Issuer hereunder
that the Borrower will not make such payment in full, the Agent may assume that
the Borrower has made such payment in full to the Agent on such date and the
Agent may, in reliance upon such assumption, cause to be distributed to each
Lender or the LC Issuer, as applicable, on such due date an amount equal to the
amount then due such Lender or the LC Issuer. If and to the extent the Borrower
shall not have so made such payment in full to the Agent, each Lender or the LC
Issuer, as applicable, shall repay to the Agent forthwith on demand such amount
distributed to such Lender or the LC Issuer together with interest thereon, for
each day from the date such amount is distributed to such Lender or the LC
Issuer until the date such Lender or the LC Issuer repays such amount to the
Agent, at the Federal Funds Rate.

          SECTION 2.13. Taxes. (a) Subject to the exclusions set forth below in
this Section 2.13(a) and, if applicable, compliance with Section 2.13(e), any
and all payments by the Borrower hereunder or under the Notes shall be made, in
accordance with Section 2.12, free and clear of and without deduction for any
and all present or future taxes, levies, imposts, deductions, charges or
withholdings, and all liabilities with respect thereto, excluding, in the case
of each Lender, the LC Issuer and the Agent, any and all present or future
taxes, levies, imposts, deductions, charges or withholdings imposed on its
income, and franchise taxes imposed on it in lieu of income taxes, (i) by the
jurisdiction under the laws of which such Lender, the LC Issuer or the Agent (as
the case may be) is organized or any political subdivision thereof and (ii), in
the case of each Lender and the LC Issuer, by the jurisdiction of such Lender's
or the LC Issuer's Applicable Lending Office or any political subdivision
thereof (all such non-excluded taxes, levies, imposts, deductions, charges,
withholdings and liabilities in respect of payments hereunder or under the Notes
being hereinafter referred to as "Taxes"). Notwithstanding the above, if the
Borrower shall be required by law to deduct any Taxes from or in respect of any
sum payable hereunder or under any Note to any Lender, the LC Issuer or the
Agent, the Borrower will so deduct and (i) the sum payable shall be increased as
may be necessary so that after making all such deductions on account of Taxes
(including deductions on account of Taxes applicable to additional sums payable
under this Section 2.13) such Lender, the LC Issuer or the Agent (as the case
may be) receives an amount equal to the sum it would have received had no such
deductions been made, (ii) the Borrower shall make such deductions and (iii) the
Borrower

                                       21

<PAGE>

shall pay the full amount deducted to the relevant taxation authority or other
authority in accordance with applicable law.

     (b) The Borrower agrees to pay any present or future stamp or documentary
taxes or any other excise or property taxes, charges or similar levies that
arise from any payment made hereunder or under the Notes or from the execution,
delivery or registration of this Agreement or the Notes (hereinafter referred to
as "Other Taxes").

     (c) Without duplication of the Borrower's payment obligations on account of
Taxes or Other Taxes pursuant to Sections 2.13(a) and (b), the Borrower shall
indemnify each Lender, the LC Issuer and the Agent for the full amount of Taxes
or Other Taxes (including, without limitation, any Taxes imposed by any
jurisdiction on amounts payable under this Section 2.13) imposed on or paid by
such Lender or the Agent (as the case may be) and any liability (including
penalties, interest and expenses) arising therefrom or with respect thereto.
This indemnification shall be made within 30 days from the date such Lender, the
LC Issuer or the Agent (as the case may be) makes written demand therefor.

     (d) Within 30 days after the date of any payment of Taxes, the Borrower
shall furnish to the Agent, at its address referred to in Section 8.02, the
original or a certified copy of a receipt evidencing payment thereof. In the
case of any payment hereunder or under the Notes by or on behalf of the Borrower
through an account or branch outside the United States or by or on behalf of the
Borrower by a payor that is not a United States person, if the Borrower
determines that no Taxes are payable in respect thereof, the Borrower shall
furnish, or shall cause such payor to furnish, to the Agent, at such address, an
opinion of counsel acceptable to the Agent stating that such payment is exempt
from Taxes. For purposes of this subsection (d) and subsection (e), the terms
"United States" and "United States person" shall have the meanings specified in
Section 7701 of the Internal Revenue Code.

     (e) Each Lender organized under the laws of a jurisdiction outside the
United States, on or prior to the date of its execution and delivery of this
Agreement in the case of each Initial Lender and on the date of the Assignment
and Acceptance pursuant to which it becomes a Lender in the case of each other
Lender, and from time to time thereafter as requested in writing by the Borrower
(but only so long as such Lender remains lawfully able to do so), shall provide
each of the Agent and the Borrower with two original Internal Revenue Service
Form W-8BEN or W-8ECI, as appropriate, or any successor or other form prescribed
by the Internal Revenue Service, certifying that such Lender is exempt from
United States withholding tax on payments pursuant to this Agreement or the
Notes. If any form or document referred to in this subsection (e) requires the
disclosure of information, other than information necessary to compute the tax
payable and information required on the date hereof by Internal Revenue Service
Form W-8BEN or W-8ECI, that the Lender reasonably considers to be confidential,
the Lender shall give notice thereof to the Borrower and shall not be obligated
to include in such form or document such confidential information; however, such
a Lender will not be entitled to any payment or indemnification on account of
any Taxes imposed by the United States.

     (f) Notwithstanding any provision to the contrary in this Agreement, the
Borrower will not be obligated to make payments on account of or indemnify the
Lenders, the LC Issuer or the Agent for any present or future taxes, levies,
imposts, deductions, charges or withholdings,

                                       22

<PAGE>

and all liabilities with respect thereto, or any present or future stamp or
other documentary taxes or property taxes, charges or similar levies that are
neither Taxes nor Other Taxes.

     (g) For any period with respect to which a Lender has failed to provide the
Borrower with the appropriate form described in Section 2.13(e) (other than if
such failure is due to a change in law occurring subsequent to the date on which
a form originally was required to be provided, or if such form otherwise is not
required under the first sentence of subsection (e) above), such Lender shall
not be entitled to indemnification under Section 2.13(a) or (c) with respect to
Taxes imposed by the United States by reason of such failure; provided, however,
that should a Lender become subject to Taxes because of its failure to deliver a
form required hereunder, the Borrower shall take such steps as the Lender shall
reasonably request to assist the Lender to recover such Taxes.

     (h) In the event that a Lender demands payment from the Borrower for
amounts owing pursuant to subsection (a) or (b) of this Section 2.13, the
Borrower may, upon payment of such amounts and subject to the requirements of
Sections 8.04 and 8.07, substitute for such Lender another financial
institution, which financial institution shall be an Eligible Assignee and shall
assume the Commitments of such Lender and purchase the Outstanding Credit
Exposures held by such Lender in accordance with Section 8.07, provided,
however, that (i) no Default shall have occurred and be continuing, (ii) the
Borrower shall have satisfied all of its obligations in connection with the Loan
Documents with respect to such Lender, and (iii) if such assignee is not a
Lender, (A) such assignee is acceptable to the Agent and (B) the Borrower shall
have paid the Agent a $3,000 administrative fee.

     (i) Notwithstanding any provision to the contrary in this Agreement, in the
event that a Lender that is not an Initial Lender and who purchased its interest
in this Agreement without the consent of the Borrower pursuant to Section
8.07(a), seeks (i) payment of additional amounts pursuant to Section 2.13(a),
(ii) payment of Other Taxes pursuant to Section 2.13(b), or (iii)
indemnification for Taxes or Other Taxes pursuant to Section 2.13(c), the amount
of any such payment or indemnification will be no greater than what it would
have been had the Initial Lender not transferred, assigned or sold its interest
in this Agreement.

          SECTION 2.14. Sharing of Payments, Etc. If any Lender shall obtain any
payment (whether voluntary, involuntary, through the exercise of any right of
set-off, or otherwise) on account of the Outstanding Credit Exposures owing to
it (other than pursuant to Section 2.10, 2.13 or 8.04(c)) in excess of its
ratable share of payments on account of the Aggregate Outstanding Credit
Exposures obtained by all of the Lenders, such Lender shall forthwith purchase
from the other Lenders such participations in the Aggregate Outstanding Credit
Exposures owing to them as shall be necessary to cause such purchasing Lender to
share the excess payment ratably with each of them; provided, however, that if
all or any portion of such excess payment is thereafter recovered from such
purchasing Lender, such purchase from each Lender shall be rescinded and such
Lender shall repay to the purchasing Lender the purchase price to the extent of
such recovery together with an amount equal to such Lender's ratable share
(according to the proportion of (i) the amount of such Lender's required
repayment to (ii) the total amount so recovered from the purchasing Lender) of
any interest or other amount paid or payable by the purchasing Lender in respect
of the total amount so recovered. The

                                       23

<PAGE>

Borrower agrees that any Lender so purchasing a participation from another
Lender pursuant to this Section 2.14 may, to the fullest extent permitted by
law, exercise all its rights of payment (including the right of set-off) with
respect to such participation as fully as if such Lender were the direct
creditor of the Borrower in the amount of such participation.

          SECTION 2.15. Use of Proceeds. The proceeds of the Reimbursement
Advances shall be available (and the Borrower agrees that it shall use such
proceeds) solely to satisfy only Reimbursement Obligations as contemplated in
Section 2.01; and Facility LCs shall be issued hereunder (and the Borrower
agrees that it shall use such Facility LCs) solely for general corporate
purposes of the Borrower and its Subsidiaries.

          SECTION 2.16. Facility LCs. (a) Issuance. The LC Issuer hereby agrees,
on the terms and conditions set forth in this Agreement, to issue standby
letters of credit for the account of the Borrower and for the benefit of the
Borrower or any Subsidiary of the Borrower (each, a "Facility LC") and to renew,
extend, increase, decrease or otherwise modify each Facility LC ("Modify", and
each such action a "Modification"), from time to time from and including the
date of this Agreement and prior to the Commitment Termination Date upon the
request of the Borrower; provided that immediately after each such Facility LC
is issued or Modified, the Aggregate Outstanding Credit Exposures shall not
exceed the aggregate of all the Commitments. No Facility LC shall have an expiry
date later than the earlier of (x) the Commitment Termination Date and (y) one
year after its issuance; provided that any Facility LC with a one-year term may
provide for the renewal thereof for additional one-year periods (which shall in
no event extend beyond the date referenced in clause (x) above). In addition, no
Facility LC shall provide that the stated amount of such Facility LC may, by its
terms or by the terms of any Facility LC Application, be automatically increased
by an amount in excess of the stated amount of such Facility LC as of the
original issuance date thereof.

     (b) Participations. Upon the issuance or Modification by the LC Issuer of a
Facility LC in accordance with this Section 2.16, the LC Issuer shall be deemed,
without further action by any party hereto, to have unconditionally and
irrevocably sold to each Lender, and each Lender shall be deemed, without
further action by any party hereto, to have unconditionally and irrevocably
purchased from the LC Issuer, a participation in such Facility LC (and each
Modification thereof) and the related LC Obligations in proportion to its Pro
Rata Share.

     (c) Notice. Subject to Section 2.16(a), the Borrower shall give the LC
Issuer and the Agent notice prior to 11:00 a.m. (New York City time) at least
five Business Days prior to the proposed date of issuance or Modification of
each Facility LC, specifying the beneficiary, the proposed date of issuance (or
Modification) and the expiry date of such Facility LC, and describing the
proposed terms of such Facility LC and the nature of the transactions proposed
to be supported thereby. Upon receipt of such notice, the Agent shall promptly
notify each Lender of the contents thereof and of the amount of such Lender's
participation in such proposed Facility LC. The issuance or Modification by the
LC Issuer of any Facility LC shall, in addition to the conditions precedent set
forth in Article III (the satisfaction of which the LC Issuer shall have no duty
to ascertain), be subject to the conditions precedent that such Facility LC
shall be satisfactory to the LC Issuer and that the Borrower shall have executed
and delivered such application agreement and/or such other instruments and
agreements relating to such Facility LC as the LC Issuer shall have reasonably
requested (each, a "Facility LC Application"). In the

                                       24

<PAGE>

event of any conflict between the terms of this Agreement and the terms of any
Facility LC Application, the terms of this Agreement shall control.

     (d) Administration; Reimbursement by Lenders. Upon receipt from the
beneficiary of any Facility LC of any demand for payment under such Facility LC,
the LC Issuer shall notify the Agent and the Agent shall promptly notify the
Borrower and each other Lender as to the amount to be paid by the LC Issuer as a
result of such demand and the proposed payment date (the "LC Payment Date"). The
responsibility of the LC Issuer to the Borrower and each Lender shall be only to
determine that the documents (including each demand for payment) delivered under
each Facility LC in connection with such presentment shall be in conformity in
all material respects with such Facility LC. The LC Issuer shall endeavor to
exercise the same care in the issuance and administration of the Facility LCs
issued by the LC Issuer as it does with respect to letters of credit in which no
participations are granted, it being understood that each Lender shall be
unconditionally and irrevocably liable without regard to the occurrence of any
Default or any condition precedent whatsoever to reimburse the LC Issuer on
demand for (i) such Lender's Pro Rata Share of the amount of each payment made
by the LC Issuer under each Facility LC issued by the LC Issuer to the extent
such amount is not reimbursed by the Borrower pursuant to Section 2.16(e) below,
plus (ii) interest on the foregoing amount to be reimbursed by such Lender, for
each day from the date of the LC Issuer's demand for such reimbursement (or, if
such demand is made after 11:00 a.m. (New York City time) on such date, from the
next succeeding Business Day) to the date on which such Lender pays the amount
to be reimbursed by it, at a rate of interest per annum equal to the Federal
Funds Rate for the first three days and, thereafter, at a rate of interest equal
to the rate applicable to Eurodollar Rate Advances.

     (e) Reimbursement by Borrower. The Borrower shall be irrevocably and
unconditionally obligated to reimburse the LC Issuer on or before the applicable
LC Payment Date for any amounts to be paid by the LC Issuer upon any drawing
under any Facility LC issued by the LC Issuer, without presentment, demand,
protest or other formalities of any kind; provided that neither the Borrower nor
any Lender shall hereby be precluded from asserting any claim for direct (but
not consequential) damages suffered by the Borrower or such Lender to the
extent, but only to the extent, caused by (i) the willful misconduct or gross
negligence of the LC Issuer in determining whether a request presented under any
Facility LC issued by it complied with the terms of such Facility LC or (ii) the
LC Issuer's failure to pay under any Facility LC issued by it after the
presentation to it of a request strictly complying with the terms and conditions
of such Facility LC. All such amounts paid by the LC Issuer and remaining unpaid
by the Borrower shall bear interest, payable on demand, for each day until paid
at a rate per annum equal to (x) the rate applicable to Base Rate Advances for
such day if such day falls on or before the applicable LC Payment Date and (y)
the sum of 2% plus the rate applicable to Base Rate Advances for such day if
such day falls after such LC Payment Date. The LC Issuer will pay to each Lender
ratably in accordance with its Pro Rata Share all amounts received by it from
the Borrower for application in payment, in whole or in part, of the
Reimbursement Obligation in respect of any Facility LC issued by the LC Issuer,
but only to the extent such Lender has made payment to the LC Issuer in respect
of such Facility LC pursuant to Section 2.16(d). Subject to the terms and
conditions of this Agreement (including without limitation the submission of a
Notice of Borrowing in compliance with Section 2.02(a) and the satisfaction of
the applicable

                                       25

<PAGE>

conditions precedent set forth in Section 3.02), the Borrower may request a
Reimbursement Advance hereunder for the purpose of satisfying any Reimbursement
Obligation.

     (f) Obligations Absolute. The Borrower's obligations under this Section
2.16 shall be absolute and unconditional under any and all circumstances and
irrespective of any setoff, counterclaim or defense to payment which the
Borrower may have or have had against the LC Issuer, any Lender or any
beneficiary of a Facility LC. The Borrower further agrees with the LC Issuer and
the Lenders that the LC Issuer and the Lenders shall not be responsible for, and
the Borrower's Reimbursement Obligation in respect of any Facility LC shall not
be affected by, among other things, the validity or genuineness of documents or
of any endorsements thereon, even if such documents should in fact prove to be
in any or all respects invalid, fraudulent or forged, or any dispute between or
among the Borrower, any of its Affiliates, the beneficiary of any Facility LC or
any financing institution or other party to whom any Facility LC may be
transferred or any claims or defenses whatsoever of the Borrower or of any of
its Affiliates against the beneficiary of any Facility LC or any such
transferee. The LC Issuer shall not be liable for any error, omission,
interruption or delay in transmission, dispatch or delivery of any message or
advice, however transmitted, in connection with any Facility LC. The Borrower
agrees that any action taken or omitted by the LC Issuer or any Lender under or
in connection with each Facility LC and the related drafts and documents, if
done without gross negligence or willful misconduct, shall be binding upon the
Borrower and shall not put the LC Issuer or any Lender under any liability to
the Borrower. Nothing in this Section 2.16(f) is intended to limit the right of
the Borrower to make a claim against the LC Issuer for damages as contemplated
by the proviso to the first sentence of Section 2.16(e).

     (g) Actions of LC Issuer. The LC Issuer shall be entitled to rely, and
shall be fully protected in relying, upon any Facility LC, draft, writing,
resolution, notice, consent, certificate, affidavit, letter, cablegram,
telegram, telecopy, telex or teletype message, statement, order or other
document believed by it to be genuine and correct and to have been signed, sent
or made by the proper Person or Persons, and upon advice and statements of legal
counsel, independent accountants and other experts selected by the LC Issuer.
The LC Issuer shall be fully justified in failing or refusing to take any action
under this Agreement unless it shall first have received such advice or
concurrence of the Required Lenders as it reasonably deems appropriate or it
shall first be indemnified to its reasonable 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. Notwithstanding any other
provision of this Section 2.16, the LC Issuer shall in all cases be fully
protected in acting, or in refraining from acting, under this Agreement in
accordance with a request of the Required Lenders, and such request and any
action taken or failure to act pursuant thereto shall be binding upon the
Lenders and any future holders of a participation in any Facility LC.

     (h) Lenders' Indemnification. Each Lender shall, ratably in accordance with
its Pro Rata Share, indemnify the LC Issuer, its Affiliates and their respective
directors, officers, agents and employees (to the extent not reimbursed by the
Borrower) against any cost, expense (including reasonable counsel fees and
disbursements), claim, demand, action, loss or liability (except such as result
from such indemnitees' gross negligence or willful misconduct or the LC Issuer's
failure to pay under any Facility LC after the presentation to it of a request
strictly complying with the terms and conditions of the Facility LC) that such
indemnitees may suffer or

                                       26

<PAGE>

incur in connection with this Section 2.16 or any action taken or omitted by
such indemnitees hereunder.

     (i) Facility LC Collateral Account. The Borrower agrees that it will, upon
the request of the Agent or the Required Lenders and until the final expiration
date of any Facility LC and thereafter as long as any amount is payable to the
LC Issuer or the Lenders in respect of any Facility LC, maintain a special
collateral account pursuant to arrangements satisfactory to the Agent (the
"Facility LC Collateral Account") at the Agent's office at the address specified
pursuant to Section 8.02, in the name of the Borrower but under the sole
dominion and control of the Agent, for the benefit of the Lenders and in which
the Borrower shall have no interest other than as set forth in Section 2.09(b)
and Section 6.01. The Borrower hereby pledges, assigns and grants to the Agent,
on behalf of and for the ratable benefit of the Lenders and the LC Issuer, a
security interest in all of the Borrower's right, title and interest in and to
all funds which may from time to time be on deposit in the Facility LC
Collateral Account to secure the prompt and complete payment and performance of
the Obligations (including, without limitation, any contingent reimbursement
obligations in respect of any undrawn amounts under any Facility LCs). The Agent
will invest any funds on deposit from time to time in the Facility LC Collateral
Account in certificates of deposit of the Agent having a maturity not exceeding
30 days. Nothing in this Section 2.16(i) shall either obligate the Agent to
require the Borrower to deposit any funds in the Facility LC Collateral Account
or limit the right of the Agent to release any funds held in the Facility LC
Collateral Account in each case other than as required by Section 2.09(b) or
Section 6.01.

     (j) Rights as a Lender. In its capacity as a Lender, the LC Issuer shall
have the same rights and obligations as any other Lender.

          SECTION 2.17. Noteless Agreement; Evidence of Indebtedness.

     (a) Each Lender shall maintain in accordance with its usual practice an
account or accounts evidencing the indebtedness of the Borrower to such Lender
resulting from each Credit Extension made by such Lender from time to time,
including the amounts of principal and interest payable and paid to such Lender
from time to time hereunder.

     (b) The Agent shall also maintain accounts in which it will record (i) the
date and the amount of each Credit Extension made hereunder and the Interest
Period, if any, applicable thereto, (ii) the amount of any principal or interest
due and payable or to become due and payable from the Borrower to each Lender
hereunder, (iii) the effective date and amount of each Assignment and Acceptance
delivered to and accepted by it and the parties thereto pursuant to Section
8.07, (iv) the amount of any sum received by the Agent hereunder from the
Borrower and each Lender's share thereof, (v) the original stated amount of each
Facility LC and the amount of LC Obligations outstanding at any time, and (vi)
all other appropriate debits and credits as provided in this Agreement,
including, without limitation, all fees, charges, expenses and interest.

     (c) The entries maintained in the accounts maintained pursuant to clauses
(a) and (b) above shall be prima facie evidence of the existence and amounts of
the obligations hereunder and under the Notes therein recorded; provided,
however, that the failure of the Agent or any

                                       27

<PAGE>

Lender to maintain such accounts or any error therein shall not in any manner
affect the obligation of the Borrower to repay such obligations in accordance
with their terms.

     (d) Any Lender may request that its Reimbursement Advances be evidenced by
a promissory note representing its Reimbursement Advances substantially in the
form of Exhibit A (each, a "Note"). In such event, the Borrower shall prepare,
execute and deliver to such Lender such Note payable to the order of such
Lender. Thereafter, the Reimbursement Advances evidenced by each such Note and
interest thereon shall at all times (including after any assignment pursuant to
Section 8.07) be represented by one or more Notes payable to the order of the
payee named therein or any assignee pursuant to Section 8.07, except to the
extent that any such Lender or assignee subsequently returns any such Note for
cancellation and requests that such Reimbursement Advances once again be
evidenced as described in clauses (a) and (b) above.

          SECTION 2.18. Extension of Commitment Termination Date. Unless the
Agent or the Borrower shall have delivered written notice of termination of this
Agreement as of the then effective Commitment Termination Date (a "Termination
Notice") to the Borrower and the Lenders, in the case of any such Termination
Notice from the Agent, or the Agent and the Lenders, in the case of any such
Termination Notice from the Borrower, which Termination Notice shall have been
delivered no later than sixty (60) days prior to the Commitment Termination Date
then in effect, and so long as no Default or Event of Default has occurred and
is continuing as of the then effective Commitment Termination Date (without
giving effect to such extension), the Commitment Termination Date shall, subject
to the provisions of this Section and provided that the Borrower shall not have
elected to convert the Aggregate Outstanding Credit Exposures to a term loan as
set forth in Section 2.19, automatically be extended for an additional one-year
period, and the Borrower shall be deemed to have made each of the statements in
Section 3.02(a) as of such then effective Commitment Termination Date.

          SECTION 2.19. Conversion to Term Loan. If the Borrower so elects by
(i) delivery of a written notice to the Agent (a "Notice to Convert") at least
three (3) but not more than ten (10) Business Days prior to the date of the then
current Commitment Termination Date and (ii) the cancellation and return of all
outstanding Facility LCs (or, alternatively, with respect to each such Facility
LC, the furnishing to the Agent of a cash deposit for deposit into the Facility
LC Collateral Account equal to 105% of the Collateral Shortfall Amount as of
such date), and (iii) the payment in full of all accrued and unpaid fees, then
on such date (the "Loan Conversion Date") the Commitments shall be terminated
and the then aggregate outstanding principal amount of the Reimbursement
Advances and all Reimbursement Obligations shall be converted to a term loan
which shall, in the case of each Lender, be in the amount of such Lender's
outstanding Reimbursement Advances and Reimbursement Obligations on such date,
and which shall be due and payable in full, together with accrued interest, on
the Facility Termination Date; provided, that no such conversion shall occur if
a Default or Event of Default has occurred and is continuing either on the date
of delivery of such Notice to Convert or on the Loan Conversion Date. The Agent
shall promptly deliver a copy of such Notice to Convert to each Lender. Upon
delivery of such Notice to Convert, the Borrower's option to borrow and reborrow
Reimbursement Advances shall terminate, and such Notice to Convert shall include
a representation and warranty by the Borrower that the conditions contained in
Section 3.02 have been or will be satisfied as of the date of such Notice to
Convert and as of the Loan Conversion

                                       28

<PAGE>

Date. Amounts repaid or prepaid following any such conversion may not be
reborrowed. If such term loan conversion has not previously been completed, then
on the Commitment Termination Date, the Commitments shall be terminated and the
Borrower shall pay in full any Aggregate Outstanding Credit Exposures and all
other unpaid Obligations.

<PAGE>

          SECTION 3.03. Determinations Under Section 3.01. For purposes of
determining compliance with the conditions specified in Section 3.01, each
Lender shall be deemed to have consented to, approved or accepted or to be

                   ARTICLE IV: REPRESENTATIONS AND WARRANTIES

          SECTION 4.01. Representations and Warranties of the Borrower. The

or enforceable against the Borrower, or the Borrower shall so state in writing;

then, and in any such event, the Agent (i) shall at the request, or may with the
consent, of the Required Lenders, by notice to the Borrower, declare the
obligation of each Lender and the LC Issuer to make Credit Extensions to be
terminated, whereupon the same shall forthwith terminate, (ii) shall at the
request, or may with the consent, of the Required Lenders, by notice to the

undrawn stated amount under all Facility LCs outstanding at such time), all
interest thereon and all other amounts payable under this Agreement to be
forthwith due and payable, whereupon the Aggregate Outstanding Credit Exposures
(other than the undrawn stated amount under all Facility LCs outstanding at such
time), all such interest and all such amounts shall become and be forthwith due
and payable, without presentment, demand, protest or further notice of any kind,
all of which are hereby expressly waived by the Borrower and (iii) shall at the
request, or may with the consent, of the Required Lenders upon notice to the
Borrower and in addition to the continuing right to demand payment of all
amounts payable under this Agreement, make demand on the Borrower to pay, and
the Borrower will, forthwith upon such demand and without any further notice or
act, pay to the Agent the Collateral Shortfall Amount, which funds shall be
deposited in the Facility LC Collateral Account; provided, however, that in the
event of an actual or deemed entry of an order for relief with respect to the
Borrower under the Federal Bankruptcy Code, (A) the obligation of each Lender
and the LC Issuer to make Credit Extensions shall automatically be terminated,
(B) the Aggregate Outstanding Credit Exposures (other than the undrawn stated

the Collateral Shortfall Amount, which funds shall be held in the Facility LC
Collateral Account. If at any time while any Default is continuing, the Agent
determines that the Collateral Shortfall Amount at such time is greater than
zero, the Agent may make demand on the Borrower to pay, and the Borrower will,
forthwith upon such demand and without any further notice or act, pay to the
Agent the Collateral Shortfall Amount, which funds shall be deposited in the
Facility LC Collateral Account. The Agent may at any time or from time to time
after funds are deposited in the Facility LC Collateral Account, apply such
funds to the payment of the Obligations and any other amounts as shall from time
to time have become due and payable by the Borrower to the Lenders or the LC
Issuer under the Loan Documents. At any time while any Default is continuing,
neither the Borrower nor any Person claiming on behalf of or through the
Borrower shall have any right to withdraw any of the funds held in the Facility
LC Collateral Account. After all of the Obligations have been indefeasibly paid
in full and the aggregate Commitments have been terminated, any funds remaining
in the Facility LC Collateral Account shall be returned by the Agent to the
Borrower or paid to whomever may be legally entitled thereto at such time.

                             ARTICLE VII: THE AGENT

          SECTION 7.01. Authorization and Action. Each Lender hereby appoints
and authorizes the Agent to take such action as agent on its behalf and to
exercise such powers and discretion under this Agreement as are delegated to the
Agent by the terms hereof, together

                                       38

<PAGE>

with such powers and discretion as are reasonably incidental thereto. As to any
matters not expressly provided for by this Agreement (including, without
limitation, enforcement or collection of the Outstanding Credit Exposures), the
Agent shall not be required to exercise any discretion or take any action, but
shall be required to act or to refrain from acting (and shall be fully protected
in so acting or refraining from acting) upon the instructions of the Required
Lenders (or all of the Lenders to the extent required by the terms of this
Agreement), and such instructions shall be binding upon all Lenders and all
holders of Outstanding Credit Exposures; provided, however, that the Agent shall
not be required to take any action that exposes the Agent to personal liability
or that is contrary to this Agreement or applicable law. The Agent agrees to
give to each Lender prompt notice of each notice given to it by the Borrower
pursuant to the terms of this Agreement.

          SECTION 7.02. Agent's Reliance, Etc. Neither the Agent nor any of its
directors, officers, agents or employees shall be liable for any action taken or
omitted to be taken by it or them under or in connection with this Agreement,
except for its or their own gross negligence or willful misconduct. Without
limitation of the generality of the foregoing, the Agent: (i) may treat the
payee in respect of any Outstanding Credit Exposure as the owner thereof until
the Agent receives and accepts an Assignment and Acceptance entered into by the
Lender that is the payee in respect of such Outstanding Credit Exposure, as
assignor, and an Eligible Assignee, as assignee, as provided in Section 8.07;
(ii) may consult with legal counsel (including counsel for the Borrower),
independent public accountants and other experts selected by it and shall not be
liable for any action taken or omitted to be taken in good faith by it in
accordance with the advice of such counsel, accountants or experts; (iii) makes
no warranty or representation to any Lender and shall not be responsible to any
Lender for any statements, warranties or representations (whether written or
oral) made in or in connection with this Agreement; (iv) shall not have any duty
to ascertain or to inquire as to the performance or observance of any of the
terms, covenants or conditions of this Agreement on the part of the Borrower or
to inspect the property (including the books and records) of the Borrower; (v)
shall not be responsible to any Lender for the due execution, legality,
validity, enforceability, genuineness, sufficiency or value of, or the
perfection or priority of any lien or security interest created or purported to
be created under or in connection with, any Loan Document or any other
instrument or document furnished pursuant hereto; and (vi) shall incur no
liability under or in respect of this Agreement by acting upon any notice,
consent, certificate or other instrument or writing (which may be by telecopier,
telegram or telex) believed by it to be genuine and signed or sent by the proper
party or parties.

          SECTION 7.03. Scotia Capital and Affiliates. With respect to its
Commitment, the Credit Extensions made by it and any Note issued to it, Scotia
Capital shall have the same rights and powers under this Agreement as any other
Lender and may exercise the same as though it were not the Agent; and the term
"Lender" or "Lenders" shall, unless otherwise expressly indicated, include
Scotia Capital in its individual capacity. Scotia Capital and its Affiliates may
accept deposits from, lend money to, act as trustee under indentures of, accept
investment banking engagements from and generally engage in any kind of business
with, the Borrower, any of its Subsidiaries and any Person who may do business
with or own securities of the Borrower or any such Subsidiary, all as if Scotia
Capital were not the Agent and without any duty to account therefor to the
Lenders.

                                       39

<PAGE>

          SECTION 7.04. Lender Credit Decision. Each Lender acknowledges that it
has, independently and without reliance upon the Agent or any other Lender and
based on the financial statements referred to in Section 4.01 and such other
documents and information as it has deemed appropriate, made its own credit
analysis and decision to enter into this Agreement. Each Lender also
acknowledges that it will, independently and without reliance upon the Agent or
any other Lender and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking action under this Agreement.

          SECTION 7.05. Indemnification. The Lenders agree to indemnify the
Agent (to the extent not reimbursed by the Borrower), ratably according to the
respective principal amounts of their respective Outstanding Credit Exposures
(or if the Aggregate Outstanding Credit Exposures are zero or if any Credit
Extensions are owing to Persons that are not Lenders, ratably according to the
respective amounts of their Commitments), from and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind or nature whatsoever that may be
imposed on, incurred by, or asserted against the Agent in any way relating to or
arising out of any Loan Document or any action taken or omitted by the Agent
under any Loan Document, provided that no Lender shall be liable for any portion
of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements resulting from the Agent's
gross negligence or willful misconduct. Without limitation of the foregoing,
each Lender agrees to reimburse the Agent promptly upon demand for its ratable
share of any out-of-pocket expenses (including reasonable counsel fees) incurred
by the 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, any Loan Document, to the extent that the
Agent is not reimbursed for such expenses by the Borrower.

          SECTION 7.06. Successor Agent. The Agent may resign at any time by
giving written notice thereof to the Lenders and the Borrower and may be removed
at any time with or without cause by the Required Lenders. Upon any such
resignation or removal, the Required Lenders shall have the right to appoint a
successor Agent. If no successor Agent shall have been so appointed by the
Required Lenders, and shall have accepted such appointment, within 30 days after
the retiring Agent's giving of notice of resignation or the Required Lenders'
removal of the retiring Agent, then the retiring Agent may, on behalf of the
Lenders, appoint a successor Agent, which shall be a commercial bank organized
under the laws of the United States of America or of any State thereof and
having a combined capital and surplus of at least $500,000,000. Upon the
acceptance of any appointment as Agent hereunder by a successor Agent, such
successor Agent shall thereupon succeed to and become vested with all the
rights, powers, discretion, privileges and duties of the retiring Agent, and the
retiring Agent shall be discharged from its duties and obligations under this
Agreement. After any retiring Agent's resignation or removal hereunder as Agent,
the provisions of this Article VII shall inure to its benefit as to any actions
taken or omitted to be taken by it while it was Agent under this Agreement.

Delivery by telecopier of an executed counterpart of any amendment or waiver of
any provision of this Agreement or the Notes or of any Exhibit hereto to be

     (b) (i) Except as otherwise provided in Section 5.01(h), the Borrower shall
provide to the Agent all information, documents and other materials that such
Person is obligated to furnish to the Agent pursuant to this Agreement and the
other Loan Documents, including, without

                                       41

<PAGE>

limitation, all notices, requests, financial statements, financial and other
reports, certificates and other information materials, but excluding any such
communication that (i) relates to a Notice of Borrowing or other request for a

any Borrowing or other Credit Extension hereunder (all such non-excluded
communications being referred to herein collectively as "Communications"), by
transmitting the Communications in an electronic/soft medium in a format
acceptable to the Agent to such electronic mail address as the Agent shall
identify to the Borrower. In addition, the Borrower shall continue to provide
the Communications to the Agent in the manner specified in this Agreement but
only to the extent requested by the Agent. The Borrower further agrees that the
Agent may make the Communications available to the Lenders by posting the
Communications on Intralinks, or a substantially similar electronic transmission
system mutually agreeable to the Agent and the Borrower (the "Platform").
Nothing in this Section 8.02(b) shall prejudice the right of the Agent to give
any notice or other communication pursuant hereto or to any other Loan Document
in any other manner specified herein or therein.

          (ii) The Agent agrees that the receipt of the Communications by the
Agent at its e-mail address set forth in clause (i) above shall constitute
effective delivery of the Communications to the Agent for purposes of each Loan
Document. The Borrower agrees that e-mail notice to it (at the address provided
pursuant to the next sentence and deemed delivered as provided in subclause
(iii) below) specifying that Communications have been posted to the Platform
shall constitute effective delivery of such Communications to such Person under
the Loan Documents. The Borrower agrees (A) to notify the Agent in writing
(including by electronic communication) from time to time to ensure that the
Agent has on record an effective e-mail address for such Person to which the
foregoing notices may be sent by electronic transmission and (B) that the
foregoing notices may be sent to such e-mail address.

          (iii) Each party hereto agrees that any electronic communication
referred to in this clause (b) shall be deemed delivered upon the posting of a
record of such Communication as "sent" in the e-mail system of the sending party
or, in the case of any such Communication to the Agent, upon the posting of a
record of such Communication as "received" in the e-mail system of the Agent;
provided, however, that if such Communication is received by the Agent after the
normal business hours of the Agent, such Communication shall be deemed delivered
at the opening of business on the next Business Day for the Agent; provided,
further, that in the event that the Agent's e-mail system shall be unavailable
for receipt of any Communication, Borrower may deliver such Communication to the
Agent in a manner mutually agreeable to the Agent and the Borrower.

          (iv) The Borrower acknowledges and agrees that the distribution of the
Communications and other material through an electronic medium is not
necessarily secure and that there are confidentiality and other risks associated
with such distribution. THE BORROWER FURTHER ACKNOWLEDGES AND AGREES AS FOLLOWS:
(A) THE PLATFORM IS PROVIDED "AS IS" AND "AS AVAILABLE"; (B) SCOTIA CAPITAL DOES
NOT WARRANT THE ACCURACY OR COMPLETENESS OF THE

                                       42

<PAGE>

COMMUNICATIONS, OR THE ADEQUACY OF THE PLATFORM AND EXPRESSLY DISCLAIMS
LIABILITY FOR ERRORS OR OMISSIONS IN THE COMMUNICATIONS; AND (C) NO WARRANTY OF
ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING, WITHOUT LIMITATION, ANY
WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT
OF THIRD PARTY RIGHTS OR FREEDOM FROM VIRUSES OR OTHER CODE DEFECTS, IS MADE BY
SCOTIA CAPITAL IN CONNECTION WITH THE COMMUNICATIONS OR THE PLATFORM.

          (v) This clause (b) shall terminate on the date that neither Scotia
Capital nor any of its Affiliates is the Agent under this Agreement.

          SECTION 8.03. No Waiver; Remedies. No failure on the part of any
Lender or the Agent to exercise, and no delay in exercising, any right hereunder
or under any Note shall operate as a waiver thereof; nor shall any single or
partial exercise of any such right 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.

          SECTION 8.04. Costs and Expenses. (a) The Borrower agrees to pay on
demand, upon presentation of a statement of account and absent manifest error,
all reasonable costs and reasonable expenses of the Agent in connection with the
preparation, execution, delivery, administration, modification and amendment of
the Loan Document and the other documents to be delivered hereunder and
thereunder, including, without limitation, (A) all due diligence, syndication
(including printing, distribution and bank meetings), transportation, computer,
duplication, appraisal, consultant, and audit expenses and (B) the reasonable
fees and reasonable expenses of counsel for the Agent with respect thereto and
with respect to advising the Agent as to its rights and responsibilities under
the Loan Documents. The Borrower further agrees to pay on demand all reasonable
costs and reasonable expenses of the Agent, the LC Issuer and the Lenders, if
any (including, without limitation, reasonable internal and external counsel
fees and expenses, provided such fees and expenses are not duplicative), in
connection with the "workout", restructuring or enforcement (whether through
negotiations, legal proceedings or otherwise) of the Loan Documents and the
other documents to be delivered hereunder, including, without limitation,
reasonable fees and expenses of counsel for the Agent, the LC Issuer and each
Lender in connection with the enforcement of rights under this Section 8.04(a).

     (b) The Borrower agrees to indemnify, to the extent legally permissible,
and hold harmless the Agent, the LC Issuer and each Lender and each of their
Affiliates and their officers, directors, employees, agents and advisors (each,
an "Indemnified Party") from and against any and all claims, damages, losses,
liabilities and expenses (including, without limitation, reasonable fees and
expenses of counsel) that may be incurred by or asserted or awarded against any
Indemnified Party, in each case arising out of or in connection with or by
reason of, or in connection with the preparation for a defense of, any
investigation, litigation or proceeding arising out of, related to or in
connection with (i) the Loan Documents, any Facility LC, any of the transactions
contemplated herein or therein or the actual or proposed use of the proceeds of
the Credit Extensions or (ii) the actual or alleged presence of Hazardous
Materials on any property of the Borrower or any of its Subsidiaries or any
Environmental Action relating in any

                                       43

<PAGE>

way to the Borrower or any of its Subsidiaries, in each case whether or not such
investigation, litigation or proceeding is brought by the Borrower, its
directors, shareholders or creditors or an Indemnified Party or any other Person
or any Indemnified Party is otherwise a party thereto and whether or not the
transactions contemplated hereby are consummated, except to the extent such
claim, damage, loss, liability or expense is found in a final, non-appealable
judgment by a court of competent jurisdiction to have resulted from such
Indemnified Party's gross negligence or willful misconduct; provided that upon
receipt of notice of any such matter by a representative of the Agent, the LC
Issuer or any Lender, as applicable, having primary responsibility for the
relationship between the Borrower and the Agent, the LC Issuer or such Lender,
as applicable, the Agent, the LC Issuer or such Lender, as applicable, shall
promptly notify the Borrower to the extent permitted by applicable law. The
Borrower shall have no liability for any settlement effected without its prior
written consent, which consent shall not be unreasonably withheld or delayed.
The Borrower also agrees not to assert any claim against the Agent, the LC
Issuer, any Lender, any of their Affiliates, or any of their respective
directors, officers, employees, attorneys and agents, on any theory of
liability, for special, indirect, consequential or punitive damages arising out
of or otherwise relating to the Loan Documents, any Facility LC, any of the
transactions contemplated herein or therein or the actual or proposed use of the
proceeds of the Credit Extensions.

     (c) If any payment of principal of, or Conversion of, any Eurodollar Rate
Advance is made by the Borrower to or for the account of a Lender other than on
the last day of the Interest Period for such Reimbursement Advance, as a result
of a payment or Conversion pursuant to Section 2.07(d) or (e), 2.09 or 2.11,
acceleration of the maturity of the Reimbursement Advances pursuant to Section
6.01, or for any other reason, the Borrower shall, upon demand by such Lender
(with a copy of such demand to the Agent), pay to the Agent for the account of
such Lender any amounts required to compensate such Lender for any additional
losses, costs or expenses that it may reasonably incur as a result of such
payment or Conversion, including, without limitation, any loss (including loss
of anticipated profits), cost or expense incurred by reason of the liquidation
or reemployment of deposits or other funds acquired by any Lender to fund or
maintain such Credit Extension.

     (d) Without prejudice to the survival of any other agreement of the
Borrower hereunder, the agreements and obligations of the Borrower contained in
Sections 2.10, 2.13 and 8.04 shall survive the payment in full of principal,
interest and all other amounts payable hereunder and under the Notes.

          SECTION 8.05. Right of Set-off. Upon (i) the occurrence and during the
continuance of any Event of Default and (ii) the making of the request or the
granting of the consent specified by Section 6.01 to authorize the Agent to
declare the Aggregate Outstanding Credit Exposures due and payable pursuant to
the provisions of Section 6.01, each Lender, the LC Issuer and each of its
Affiliates is hereby authorized at any time and from time to time, 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 and
other indebtedness at any time owing by such Lender, the LC Issuer or such
Affiliate to or for the credit or the account of the Borrower against any and
all of the obligations of the Borrower now or hereafter existing under the Loan
Documents and any Note held by such Lender or the LC Issuer, whether or not such
Lender or the LC Issuer shall have made any demand under this Agreement or such
Note and although such

                                       44

<PAGE>

obligations may be unmatured. Each Lender and the LC Issuer agrees promptly to
notify the Borrower after any such set-off and application, provided that the
failure to give such notice shall not affect the validity of such set-off and
application. The rights of each Lender, the LC Issuer and their respective
Affiliates under this Section are in addition to other rights and remedies
(including, without limitation, other rights of set-off) that such Lender, the
LC Issuer and their respective Affiliates may have.

          SECTION 8.06. Binding Effect. This Agreement shall become effective
(other than Section 2.01, which shall only become effective upon satisfaction of
the conditions precedent set forth in Section 3.01) when it shall have been
executed by the Borrower and the Agent and when the Agent shall have been
notified by each Initial Lender that such Initial Lender has executed it and
thereafter shall be binding upon and inure to the benefit of the Borrower, the
Agent, the LC Issuer and each Lender and their respective successors and
assigns, except that the Borrower shall not have the right to assign its rights
hereunder or any interest herein without the prior written consent of the
Lenders to any Person.

          SECTION 8.07. Assignments, Designations and Participations. (a) Each
Lender may (i) with the prior consent of the Agent (which consent shall not be
unreasonably withheld and which consent shall not be required in the event of an
assignment or grant pursuant to Sections 8.07(g) or (h)), (ii) for so long as no
Default has occurred and is continuing, with the consent of the Borrower (which
consent shall not be unreasonably withheld and which consent shall not be
required in the event of an assignment or grant pursuant to Sections 8.07(g) or
(h)), and (iii) with the prior consent of the LC Issuer (which consent may be
given or withheld in the sole discretion of the LC Issuer and which consent
shall not be required in the event of an assignment or grant pursuant to
Sections 8.07(g) or (h)), assign to one or more Persons all or a portion of its
rights and obligations under this Agreement (including, without limitation, all
or a portion of its Commitment, the Outstanding Credit Exposures owed to it and
any Note or Notes held by it); provided, however, that (A) each such assignment
shall be of a constant, and not a varying, percentage of all rights and
obligations under this Agreement, (B) except in the case of an assignment to a
Person that, immediately prior to such assignment, was a Lender or an assignment
of all of a Lender's rights and obligations under this Agreement, the amount of
the Commitment of the assigning Lender being assigned pursuant to each such
assignment (determined as of the date of the Assignment and Acceptance with
respect to such assignment) shall in no event be less than $5,000,000 or an
integral multiple of $1,000,000 in excess thereof, (C) each such assignment
shall be to an Eligible Assignee, and (D) the parties to each such assignment
shall execute and deliver to the Agent, for its acceptance and recording in the
Register, an Assignment and Acceptance, together with any Note subject to such
assignment and a processing and recordation fee of $3,000. Upon such execution,
delivery, acceptance and recording, from and after the effective date specified
in each Assignment and Acceptance, (1) the assignee thereunder shall be a party
hereto and, to the extent that rights and obligations hereunder have been
assigned to it pursuant to such Assignment and Acceptance, have the rights and
obligations of a Lender hereunder and (2) the Lender assignor thereunder shall,
to the extent that rights and obligations hereunder have been assigned by it
pursuant to such Assignment and Acceptance, relinquish its rights and be
released from its obligations under this Agreement (and, in the case of an
Assignment and Acceptance covering all or the remaining portion of an

                                       45

<PAGE>

assigning Lender's rights and obligations under this Agreement, such Lender
shall cease to be a party hereto).

     (b) By executing and delivering an Assignment and Acceptance, the Lender
assignor thereunder and the assignee thereunder confirm to and agree with each
other and the other parties hereto as follows: (i) other than as provided in
such Assignment and Acceptance, such assigning Lender makes no representation or
warranty and assumes no responsibility with respect to any statements,
warranties or representations made in or in connection with this Agreement or
the execution, legality, validity, enforceability, genuineness, sufficiency or
value of, or the perfection or priority of any lien or security interest created
or purported to be created under or in connection with, this Agreement or any
other instrument or document furnished pursuant hereto; (ii) such assigning
Lender makes no representation or warranty and assumes no responsibility with
respect to the financial condition of the Borrower or the performance or
observance by the Borrower of any of its obligations under this Agreement or any
other instrument or document furnished pursuant hereto; (iii) such assignee
confirms that it has received a copy of this Agreement, together with copies of
the financial statements referred to in Section 4.01 and such other documents
and information as it has deemed appropriate to make its own credit analysis and
decision to enter into such Assignment and Acceptance; (iv) such assignee will,
independently and without reliance upon the Agent, such assigning Lender or any
other Lender and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking action under this Agreement; (v) such assignee confirms that it is an
Eligible Assignee; (vi) such assignee appoints and authorizes the Agent to take
such action as agent on its behalf and to exercise such powers and discretion
under this Agreement as are delegated to the Agent by the terms hereof, together
with such powers and discretion as are reasonably incidental thereto; and (vii)
such assignee agrees that it will perform in accordance with their terms all of
the obligations that by the terms of this Agreement are required to be performed
by it as a Lender.

     (c) Upon its receipt of an Assignment and Acceptance executed by an
assigning Lender and an assignee representing that it is an Eligible Assignee,
together with any Note or Notes subject to such assignment, the Agent shall, if
such Assignment and Acceptance has been completed and is in substantially the
form of Exhibit C hereto, (i) accept such Assignment and Acceptance, (ii) record
the information contained therein in the Register and (iii) give prompt notice
thereof to the Borrower. Within five Business Days after the Borrower's receipt
of such notice, if requested by the applicable Lender, the Borrower, at its own
expense, shall execute and deliver to the Agent in exchange for the surrendered
Note a new Note to the order of such Eligible Assignee in an amount equal to the
Commitment assumed by it pursuant to such Assignment and Acceptance and, if the
assigning Lender has retained a Commitment hereunder, if requested by such
assigning Lender, a new Note to the order of the assigning Lender in an amount
equal to the Commitment retained by it hereunder. Such new Note or Notes shall
be in an aggregate principal amount equal to the aggregate principal amount of
such surrendered Note or Notes, shall be dated the effective date of such
Assignment and Acceptance and shall otherwise be in substantially the form of
Exhibit A hereto.

     (d) The Agent shall maintain at its address referred to in Section 8.02 a
copy of each Assignment and Acceptance delivered to and accepted by it and a
register for the recordation of the names and addresses and Commitment of, and
principal amount of Outstanding Credit

                                       46

<PAGE>

Exposure owing to, each Lender from time to time (the "Register"). The entries
in the Register shall be conclusive and binding for all purposes, absent
manifest error, and the Borrower, the Agent and the Lenders may treat each
Person whose name is recorded in the Register as a Lender hereunder for all
purposes of this Agreement. The Register shall be available for inspection by
the Borrower or any Lender at any reasonable time and from time to time upon
reasonable prior notice.

     (e) Each Lender may sell participations to one or more banks or other
entities (other than the Borrower or any of its Affiliates) in or to all or a
portion of its rights and obligations under this Agreement (including, without
limitation, all or a portion of its Commitment, the Outstanding Credit Exposure
owing to it and any Note or Notes held by it); provided, however, that (i) such
Lender's obligations under this Agreement (including, without limitation, its
Commitment to the Borrower hereunder) shall remain unchanged, (ii) such Lender
shall remain solely responsible to the other parties hereto for the performance
of such obligations, (iii) such Lender shall remain the owner of such Credit
Extensions for all purposes of this Agreement, (iv) the Borrower, the 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 and
(v) no participant under any such participation shall have any right to approve
any amendment or waiver of any provision of this Agreement or any Note, or any
consent to any departure by the Borrower therefrom, except to the extent that
such amendment, waiver or consent would (A) reduce the principal of, or interest
on, the Credit Extensions or any fees or other amounts payable hereunder, or (B)
increase the Commitments, in each case to the extent subject to such
participation, or postpone any date fixed for any payment of principal of, or
interest on, the Aggregate Outstanding Credit Exposures or any fees or other
amounts payable hereunder, in each case to the extent subject to such
participation. Each participant shall be entitled to the benefits and subject to
the exclusions, in each case, as if it were a Lender, of Sections 2.10, 2.11 and
2.13 to the same extent as if it were a Lender and had acquired its interest
under this Agreement by an assignment made pursuant to this Section 8.07,
provided, however, that (i) such participant complies with the requirements of
Section 2.13(e) and (ii) in no event shall the Borrower be obligated to make any
payment with respect to such Sections that is greater than the amount that the
Borrower would have otherwise made had no participations been sold under this
Section 8.07(e).

     (f) Any Lender may, in connection with any assignment, designation or
participation or proposed assignment, designation or participation pursuant to
this Section 8.07, disclose to the assignee, designee or participant or proposed
assignee, designee or participant, any information relating to the Borrower
furnished to such Lender by or on behalf of the Borrower; provided that, prior
to any such disclosure, the assignee, designee or participant or proposed
assignee, designee or participant shall agree to preserve the confidentiality of
any Confidential Information relating to the Borrower received by it from such
Lender.

     (g) Notwithstanding any other provision set forth in this Agreement, any
Lender may at any time create a security interest in all or a portion of its
rights under this Agreement (including, without limitation, the Outstanding
Credit Exposure owing to it and the Note or Notes held by it) in favor of any
Federal Reserve Bank in accordance with Regulation A of the Board of Governors
of the Federal Reserve System.

                                       47

<PAGE>

     (h) Notwithstanding anything to the contrary contained herein, any Lender
(a "Designating Lender") may grant to one or more special purpose funding
vehicles (each an "SPV"), identified as such in writing from time to time by the
Designating Lender to the Agent and the Borrower, the option to provide to the
Borrower all or any part of any Reimbursement Advance that such Designating
Lender would otherwise be obligated to make to the Borrower or to participate in
any Facility LC pursuant to this Agreement; provided that (i) nothing herein
shall constitute a commitment by any SPV to make any Reimbursement Advance or to
participate in any Facility LC issued hereunder, (ii) if an SPV elects not to
exercise such option or otherwise fails to provide all or any part of such
Reimbursement Advance, the Designating Lender shall be obligated to make such
Reimbursement Advance pursuant to the terms hereof, (iii) the Designating Lender
shall remain liable for any indemnity or other payment obligation with respect
to its Commitment hereunder and (iv) no SPV or Designating Lender shall be
entitled to receive any greater amount under this Agreement than the Designating
Lender would have been entitled to receive had the Designating Lender not
otherwise granted such SPV the option to provide any Reimbursement Advance to
the Borrower. The making of a Reimbursement Advance by an SPV hereunder and the
participation of an SPV in any Facility LC issued hereunder shall utilize the
Commitment of the Designating Lender to the same extent, and as if, such
Reimbursement Advance or participation in such Facility LC were made by such
Designating Lender.

     (i) Each party hereto hereby acknowledges and agrees that no SPV shall have
the rights of a Lender hereunder, such rights being retained by the applicable
Designating Lender. Accordingly, and without limiting the foregoing, each party
hereby further acknowledges and agrees that no SPV shall have any voting rights
hereunder and that the voting rights attributable to any Credit Extension made
by an SPV shall be exercised only by the relevant Designating Lender and that
each Designating Lender shall serve as the administrative agent and
attorney-in-fact for its SPV and shall on behalf of its SPV receive any and all
payments made for the benefit of such SPV and take all actions hereunder to the
extent, if any, such SPV shall have any rights hereunder. No additional Note
shall be required to evidence the Credit Extensions or portion thereof made by
an SPV; and the related Designating Lender shall be deemed to hold its Note or
Notes, if any, as administrative agent for such SPV to the extent of the Credit
Extensions or portion thereof funded by such SPV. In addition, any payments for
the account of any SPV shall be paid to its Designating Lender as administrative
agent for such SPV.

     (j) Each party hereto hereby agrees that no SPV shall be liable for any
indemnity or payment under this Agreement for which a Lender would otherwise be
liable so long as, and to the extent that, the related Designating Lender
provides such indemnity or makes such payment; provided, with respect to such
agreement by the Borrower that the related Designating Lender shall not be in
breach of its obligation to make Credit Extensions to the Borrower hereunder. In
furtherance of the foregoing, each party hereto hereby agrees (which agreements
shall survive the termination of this Agreement) that prior to the date that is
one year and one day after the payment in full of all outstanding commercial
paper or other senior indebtedness of any SPV, it will not institute against, or
join any other person in instituting against, such SPV any bankruptcy,
reorganization, arrangement, insolvency or liquidation proceedings under the
laws of the United States or any State thereof; provided, with respect to such
agreement by the Borrower that the related Designating Lender shall not be in
breach of its obligation to make Credit

                                       48

<PAGE>

Extensions to the Borrower hereunder. Notwithstanding the foregoing, the
Designating Lender unconditionally agrees to indemnify the Borrower, the Agent
and each Lender against all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind or nature whatsoever which may be incurred by or asserted against the
Borrower, the Agent or such Lender, as the case may be, in any way relating to
or arising as a consequence of any such forbearance or delay in the initiation
of any such proceeding against its SPV.

     (k) In addition, notwithstanding anything to the contrary contained in
subsection 8.07(h), (i), (j) or (k) or otherwise in this Agreement, any SPV may
(i) at any time and without paying any processing fee therefor, assign or
participate all or a portion of its interest in any Outstanding Credit Exposure
to the Designating Lender or to any financial institutions providing liquidity
and/or credit support to or for the account of such SPV to support the funding
or maintenance of Outstanding Credit Exposure and (ii) disclose on a
confidential basis any non-public information relating to its Outstanding Credit
Exposure to any rating agency, commercial paper dealer or provider of any
surety, guarantee or credit or liquidity enhancements to such SPV. Subsection
8.07(h), (i), (j) or (k) may not be amended without the written consent of any
Designating Lender affected thereby.

          SECTION 8.08. Confidentiality. Neither the Agent nor the LC Issuer or
Lender shall disclose any Confidential Information to any other Person without
the consent of the Borrower, other than (a) to the Agent's, the LC Issuer's or
such Lender's Affiliates and their officers, directors, employees, agents and
advisors and, as contemplated by Section 8.07(f), to actual or prospective
assignees and participants, and then only on a confidential basis, (b) as

IMPORTANT INFORMATION ABOUT PROCEDURES FOR OPENING A NEW ACCOUNT. To help the
government fight the funding of terrorism and money laundering activities,
Federal law requires all financial institutions to obtain, verify, and record
information that identifies each person or entity that opens an account,
including any deposit account, treasury management account, loan, other
extension of credit, or other financial services product. What this means for
the Borrower: When the Borrower opens an account, the Agent and the Lenders will
ask for the Borrower's name, tax identification number, business address, and
other information that will allow the Agent and the Lenders to identify the
Borrower. The Agent and the Lenders may also ask to see the Borrower's legal
organizational documents or other identifying documents.

          For the purposes of this Schedule, the following terms have the
following meanings, subject to the final paragraph of this Schedule:

          "Level I Status" exists at any date if, on such date, the Borrower's
Moody's Rating is A3 or better or the Borrower's S&P Rating is A- or better.

          "Level II Status" exists at any date if, on such date, (i) the
Borrower has not qualified for Level I Status and (ii) the Borrower's Moody's
Rating is Baa1 or better or the Borrower's S&P Rating is BBB+ or better.

          "Level III Status" exists at any date if, on such date, (i) the
Borrower has not qualified for Level I Status or Level II Status and (ii) the
Borrower's Moody's Rating is Baa2 or better or the Borrower's S&P Rating is BBB
or better.

          "Level IV Status" exists at any date if, on such date, (i) the
Borrower has not qualified for Level I Status, Level II Status or Level III
Status and (ii) the Borrower's Moody's Rating is Baa3 or better or the
Borrower's S&P Rating is BBB- or better.

          "Level V Status" exists at any date if, on such date, (i) the Borrower
has not qualified for Level I Status, Level II Status, Level III Status or Level
IV Status and (ii) the Borrower's Moody's Rating is Ba1 or better or the
Borrower's S&P Rating is BB+ or better.

          "Level VI Status" exists at any date if, on such date, the Borrower
has not qualified for Level I Status, Level II Status, Level III Status, Level
IV Status or Level V Status.

<PAGE>

          "Moody's Rating" means, at any time, the rating issued by Moody's and
then in effect with respect to the Borrower's senior unsecured long-term debt
securities without third-party credit enhancement.

          "S&P Rating" means, at any time, the rating issued by S&P and then in
effect with respect to the Borrower's senior unsecured long-term debt securities
without third-party credit enhancement.

          "Status" means Level I Status, Level II Status, Level III Status,
Level IV Status, Level V Status or Level VI Status.

          The Applicable Margin, the Applicable LC Fee Rate and Applicable
Commitment Fee Rate shall be determined in accordance with the foregoing table
based on the Borrower's Status as determined from its then-current Moody's and
S&P Ratings. The credit rating in effect on any date for the purposes of this
Schedule is that in effect at the close of business on such date. If at any time
the Borrower does not have both a Moody's Rating and an S&P Rating, Level VI
Status shall exist; provided, however, that if the credit rating system of
Moody's or S&P shall change, or if either such rating agency shall cease to be
in the business of rating corporate debt obligations, the Borrower and the
Lenders shall negotiate in good faith to amend this Schedule to reflect such
changed rating system or the unavailability of ratings from such rating agency
and, pending the effectiveness of any such amendment, the applicable Status for
the Borrower shall be the Borrower's Status most recently in effect prior to
such change or cessation.

          Except as specifically provided above in this Schedule, in the event
that a split occurs between the two ratings, then the rating corresponding to
the higher of the two ratings shall apply. However, if the split is greater than
one level, then the pricing shall be based upon the rating one level above the
lower of the two ratings.

agree as follows:

          1. The Assignor hereby sells and assigns to the Assignee, and the
Assignee hereby purchases and assumes from the Assignor, an interest in and to

          2. The Assignor (i) represents and warrants that it is the legal and
beneficial owner of the interest being assigned by it hereunder and that such
interest is free and clear of any adverse claim; (ii) makes no representation or

equal to the Commitment assumed by the Assignee pursuant hereto and the
Agreement and the Assignor in an amount equal to the Commitment retained by the
Assignor under the Agreement, respectively, as specified on Schedule 1 hereto.

          3. The Assignee (i) confirms that it has received a copy of the
Agreement, together with copies of the financial statements referred to in each
Section 4.01 thereof and such other documents and information as it has deemed
appropriate to make its own credit analysis and decision to enter into this
Assignment and Acceptance; (ii) agrees that it will, independently and without
reliance upon the Agent, the Assignor or any other Lender and based on such
documents and information as it shall deem appropriate at the time, continue to
make its own credit decisions in taking or not taking action under the
Agreement; (iii) confirms that it is an Eligible Assignee; (iv) appoints and
authorizes the Agent to take such action as agent on its behalf and to exercise
such powers and discretion under the Agreement as are delegated to the Agent by
the terms thereof, together with such powers and discretion as are reasonably
incidental thereto; (v) agrees that it will perform in accordance with their
terms all of the obligations that by

<PAGE>

                            OPINION OF ASSOCIATE GENERAL COUNSEL TO THE BORROWER

                                December 16, 2005

To each of the Lenders party to the
Agreement defined below

DTE Energy Company

Ladies and Gentlemen:

          This opinion is furnished to you pursuant to Section 3.01(g)(iv) of
the Letter of Credit and Reimbursement Agreement, dated as of December 16, 2005,
among DTE Energy Company (the "Borrower"), the Lenders party thereto, and The
Bank of Nova Scotia ("Scotia Capital"), as Administrative Agent (the
"Agreement"). Terms defined in the Agreement are used herein as therein defined.

          I am the Associate General Counsel of the Borrower, and have acted as
counsel for the Borrower in connection with the preparation, execution and
delivery of the Loan Documents.

          In that connection, I, in conjunction with the members of my staff,
have examined:

          (i) Each Loan Document, executed by each of the parties thereto.

          (ii) The other documents furnished by the Borrower pursuant to Article
     III of the Agreement.

          (iii) The Restated Articles of Incorporation of the Borrower and all
     amendments thereto (the "Charter").

          (iv) The Bylaws of the Borrower and all amendments thereto (the
     "Bylaws").

          (v) A certificate from the State of Michigan attesting to the
     continued corporate existence and good standing of the Borrower.

In addition, I have examined the originals, copies certified to my satisfaction,
of such other corporate records of the Borrower, certificates of public
officials and of officers of the Borrower, and agreements, instruments and other
documents, as I have deemed necessary as a basis for the opinions expressed
below. As to questions of fact material to such opinions, I have, when relevant
facts were not independently established by me, relied upon certificates of
public officials. I have assumed the due execution and delivery, pursuant to due
authorization, of the Agreement by the Lenders and the Agent.

          My opinions expressed below are limited to the law of the State of
Michigan and the federal law of the United States.

<PAGE>

          Based upon the foregoing and upon such investigation as I have deemed
necessary, I am of the following opinion:

          1. The Borrower is a corporation duly organized, validly existing and
in good standing under the laws of the State of Michigan.

          2. The execution, delivery and performance by the Borrower of the Loan
Documents to which it is party, and the consummation of the transactions
contemplated thereby, are within the Borrower's corporate powers, have been duly
authorized by all necessary corporate action, and do not contravene (i) the
Charter or the Bylaws of the Borrower or (ii) any law, rule or regulation
applicable to the Borrower, or (iii) any contractual restriction binding on or
affecting the Borrower.

          3. No consent, authorization or approval or other action by, and no
notice to or filing with, any governmental authority or regulatory body or any
other third party is required for the due execution, delivery, recordation,
filing or performance by the Borrower of the Loan Documents to which it is a
party.

          4. The Agreement has been, and each of the respective Notes when
delivered will have been, duly executed and delivered on behalf of the Borrower.

          5. Except as may have been disclosed to you in the SEC Reports, to the
best of my knowledge (after due inquiry) there are no pending or overtly
threatened actions or proceedings affecting the Borrower or any of its
Significant Subsidiaries before any court, governmental agency or arbitrator
that (i) could be reasonably likely to have a Material Adverse Effect or (ii)
purport to affect the legality, validity, or enforceability of any Loan
Documents to which the Borrower is a party or the consummation of the
transactions contemplated thereby.

          6. In a properly presented case, a Michigan court or a federal court
sitting in the State of Michigan applying Michigan choice of law rules should
give effect to the choice of law provisions of the Loan Documents and should
hold that such Loan Documents are to be governed by the laws of the State of New
York rather than the laws of the State of Michigan. In rendering the foregoing
opinion, I note that by their terms the Loan Documents expressly select New York
law as the laws governing their interpretation and that the Loan Documents
governed by New York law were delivered by the parties thereto to the Agent in
New York. The choice of law provisions of the Loan Documents are not voidable
under the laws of the State of Michigan.

          7. If, despite the provisions of Section 8.09 of the Agreement wherein
the parties thereto agree that the Loan Documents shall be governed by, and
construed in accordance with, the laws of the State of New York, a court of the
State of Michigan or a federal court sitting in the State of Michigan were to
hold that the Loan Documents are governed by, and to be construed in accordance
with the laws of the State of Michigan, the respective Loan Documents would be,
under the laws of the State of Michigan, legal, valid and binding obligations of
the Borrower, enforceable against the Borrower in accordance with their
respective terms.

          8. Neither the Borrower nor any of its Subsidiaries is an "investment
company," or an "affiliated person" of, or "promoter" or "principal underwriter"
for, an "investment company," as such terms are defined in the Investment
Company Act of 1940, as amended; and

<PAGE>

the Borrower is currently exempt from the provisions of the Public Utility
Holding Company Act of 1935, as amended (except Section 9 thereof);

          The opinions set forth above are subject to the following
qualifications:

               (a) My opinion in paragraph 7 above as to enforceability is
          subject to the effect of any applicable bankruptcy, insolvency,
          fraudulent conveyance, reorganization, moratorium or laws affecting
          creditors' rights generally.

               (b) My opinion in paragraph 7 above as to enforceability is
          subject to the effect of general principles of equity, including,
          without limitation, concepts of materiality, reasonableness, good
          faith and fair dealing (regardless of whether considered in a
          proceeding in equity or at law).

               (c) I express no opinion as to participation and the effect of
          the law of any jurisdiction other than the State of Michigan wherein
          any Lender may be located or wherein enforcement of the Loan Documents
          may be sought that limits the rates of interest legally chargeable or
          collectible.

          I am a member of the Bar of the State of Michigan, and do not express
any opinion concerning any law other than the law of the State of Michigan and
the federal laws of the United States of America.

          This opinion letter is rendered to you in connection with the
above-described transaction. This opinion letter may not be relied upon by you
for any other purpose, or relied upon by any other person or entity without my
prior written consent (provided, that this opinion letter may be furnished to
and relied upon by a subsequent assignee of, or participant under, the Agreement
and a Note, if any, solely for the purpose of such assignment or participation,
subject to the assumptions, limitations and qualifications, set forth herein,
without any prior written consent). I undertake no duty to inform you or any
assignee or participant of events occurring subsequent to the date hereof.

                                        Very truly yours,

connection with passive personal investments and community affairs that are not inconsistent with
the Executive’s duties under this Agreement. Additionally, nothing in this Section 2.3 will
prevent the Executive from serving on the Board of Directors of other companies or organizations,
or engaging in other activities, so long as such participation does not conflict with the interests
or business of Employer or require such involvement as to interfere with the performance of the
Executive’s duties hereunder and has been expressly approved by the Chief Executive Officer of
Employer. If the Executive is elected as a director of the Employer or as a director or officer of
any of its affiliates, the Executive will fulfill his duties as such director or officer without
additional compensation. The Executive acknowledges and agrees that he owes a fiduciary duty of
loyalty, fidelity and allegiance to act at all times in the best interests of the Employer.

7

 

     6.4 SEVERANCE

     Should the Executive’s employment with the Employer be terminated during the Employment Period
pursuant to Section 6.1(e) or Section 6.1(f) above, the Executive shall be entitled to:

	 	a.	 	a payment equal to one and one-half (1.5) years of his then
current Salary; and
	 
	 	b.	 	a payment equal to one and one-half (1.5) times his then
current cash bonus target amount.

     Such payments under this section will be made no later than 30 days following the termination
from employment. Severance payments do not constitute continued employment beyond the termination
date.

     6.5 CHANGE OF CONTROL

     If, within 12 months of a Change of Control, the Executive’s position is eliminated or the
Executive is terminated pursuant to Section 6.1(e) or 6.1(f) above, regardless of whether such
termination event occurs during or after the Employment Period, the Executive shall be entitled to
the following in lieu of the amounts set forth in Section 6.4:

	 	a.	 	a payment equal to one and one-half (1.5) years of his then
current Salary;
	 
	 	b.	 	a payment equal to one and one-half (1.5) times his then
current cash bonus target amount;
	 
	 	c.	 	vesting of Executive’s stock option awards, subject to the
terms and conditions of the respective stock option agreements;
	 
	 	d.	 	vesting of Executive’s restricted stock award pursuant to
Section 3.1 (e) above, subject to the terms and conditions of the Restricted
Stock Agreement; and
	 
	 	e.	 	continued medical and life insurance benefits at no cost to the
Executive, for the Executive and his dependents (including his spouse) who were
covered as of such termination event under the medical and life insurance
benefit plan as in effect for employees of the Employer during the coverage
period, or the substantial equivalence, for 18 months or until such time that
he is re-employed and is provided medical and life insurance benefits (which
coverage shall be promptly reported to the Employer by the Executive) whichever
is sooner.

8

 

     Severance payments do not constitute continued employment beyond the termination date.

     Notwithstanding anything to the contrary in this Agreement, if the Executive is a
“disqualified individual” (as defined in Section 280G(c) of the Internal Revenue Code of
1986, as amended (the “Code”)), and the severance benefits provided for in this Section
6.5, together with any other payments and benefits which the Executive has the right to
receive from the Employer and its affiliates, would constitute a “parachute payment” (as
defined in Section 280G(b)(2) of the Code), then the severance benefits provided hereunder
(beginning with any benefit to be paid in cash hereunder) shall be either (1) reduced (but
not below zero) so that the present value of such total amounts and benefits received by
the Executive will be one dollar ($1.00) less than three times the Executive’s “base
amount” (as defined in Section 280G of the Code) and so that no portion of such amounts and
benefits received by the Executive shall be subject to the excise tax imposed by Section
4999 of the Code or (2) paid in full, whichever produces the better net after-tax position
to the Executive (taking into account any applicable excise tax under Section 4999 of the
Code and any other applicable taxes). The determination as to whether any such reduction
in the amount of the severance benefit is necessary shall be made initially by the Employer
in good faith. If a reduced severance benefit is paid hereunder in accordance with clause
(1) of the first sentence of this paragraph and through error or otherwise that payment,
when aggregated with other payments and benefits from the Employer (or its affiliates) used
in determining if a “parachute payment” exists, exceeds one dollar ($1.00) less than three
times the Executive’s base amount, then the Executive shall immediately repay such excess
to the Employer upon notification that an overpayment has been made.

     6.6 NO MITIGATION

     Any remuneration received by the Executive from a third party following the Employment Period shall
not apply to reduce the Employer’s obligations to make payments hereunder.

     6.7 LIQUIDATED DAMAGES

     Due to the difficulties in estimating damages for an early termination of the Employment Period,
the Employer and the Executive agree that the payments, if any, to be received by the Executive
hereunder shall be received as liquidated damages.

7.
NON—DISCLOSURE COVENANT; EMPLOYEE INVENTIONS

     7.1 ACKNOWLEDGMENTS BY THE EXECUTIVE

     The Executive acknowledges that (a) prior to and during the Employment Period and as a part of
his employment, the Executive has been and will be afforded access to Confidential Information; (b)
public disclosure of such Confidential Information could have an adverse effect on the Employer and
its business; (c) because the Executive possesses substantial technical

9

 

expertise and skill with respect to the Employer’s business, the Employer desires to obtain
exclusive ownership of each Employee Invention, and the Employer will be at a substantial
competitive disadvantage if it fails to acquire exclusive ownership of each Employee Invention; and
(d) the provisions of this Section 7 are reasonable and necessary to prevent the improper use or
disclosure of Confidential Information and to provide the Employer with exclusive ownership of all
Employee Inventions.

     7.2 AGREEMENTS OF THE EXECUTIVE

     In consideration of the compensation and benefits to be paid or provided to the Executive by
the Employer under this Agreement, the Executive covenants the following:

	 	a.	 	Confidentiality.

	 	i.	 	The Executive will hold in confidence the
Confidential Information and will not disclose it to any person except
with the specific prior written consent of the Employer or except as
otherwise expressly permitted by the terms of this Agreement.
	 
	 	ii.	 	Any trade secrets of the Employer will be
entitled to all of the protections and benefits under any applicable
law. If any information that the Employer deems to be a trade secret
is found by a court of competent jurisdiction not to be a trade secret
for purposes of this Agreement, such information will, nevertheless, be
considered Confidential Information for purposes of this Agreement.
The Executive hereby waives any requirement that the Employer submit
proof of the economic value of any trade secret or post a bond or other
security.
	 
	 	iii.	 	None of the foregoing obligations and
restrictions applies to any part of the Confidential Information that
the Executive demonstrates was or became generally available to the
public other than as a result of a disclosure by the Executive.
	 
	 	iv.	 	The Executive will not remove from the
Employer’s premises (except to the extent such removal is for purposes
of the performance of the Executive’s duties at home or while
traveling, or except as otherwise specifically authorized by the
Employer) any document, record, notebook, plan, model, component,
device, or computer software or code, whether embodied in a disk or in
any other form (collectively, the “Proprietary Items”). The Executive
recognizes that, as between the Employer and the Executive, all of the
Proprietary Items, whether or not developed by the Executive, are the
exclusive property of the Employer. Upon termination of this Agreement
by either party, or upon the request of the Employer during the
Employment Period, the

10

 

	 	 	 	Executive will return to the Employer all of the Proprietary Items in
the Executive’s possession or subject to the Executive’s control, and
the Executive shall not retain any copies, abstracts, sketches, or
other physical embodiment of any of the Proprietary Items.

	 	b.	 	Employee Inventions. Each Employee Invention will
belong exclusively to the Employer. The Executive acknowledges that all of the
Executive’s writing, works of authorship, and other Employee Inventions are
works made for hire and the property of the Employer, including any copyrights,
patents, or other intellectual property rights pertaining thereto. If it is
determined that any such works are not works made for hire, the Executive
hereby assigns to the Employer all of the Executive’s right, title, and
interest, including all rights of copyright, patent, and other intellectual
property rights, to or in such Employee Inventions. The Executive covenants
that he will promptly:

	 	i.	 	disclose to the Employer in writing any
Employee Invention;
	 
	 	ii.	 	assign to the Employer or to a party designated
by the Employer, at the Employer’s request and without additional
compensation, all of the Executive’s right to the Employee Invention
for the United States and all foreign jurisdictions;
	 
	 	iii.	 	execute and deliver to the Employer such
applications, assignments, and other documents as the Employer may
request in order to apply for and obtain patents or other registrations
with respect to any Employee Invention in the United States and any
foreign jurisdictions;
	 
	 	iv.	 	sign all other papers necessary to carry out
the above obligations; and
	 
	 	v.	 	give testimony and render any other assistance
in support of the Employer’s rights to any Employee Invention.

11

 

	 	c.	 	Notice of Intent to Resign. Except in the event of a
resignation for Good Reason, Executive agrees to provide Employer with 90 days
advance notice of his intention to resign (“Notice Period”). During the Notice
Period, Executive shall continue in the diligent fulfillment of all duties of
his position and this Agreement. Should Executive fail to provide Employer
with the full Notice Period, Executive shall forfeit that portion of his earned
pro-rata yearly cash bonus as follows:
	 
	 	 	 	(90 — (number of full days of advance notice) / 90) X(times) pro-rata
earned yearly cash bonus = amount forfeited by Executive.
	 
	 	 	 	Pro-rata earned yearly cash bonus is: (unconditional portion of yearly cash
bonus, if any, targeted for Executive in the current Fiscal Year) / (number
of full months worked in the current Fiscal Year / 12).
	 
	 	d.	 	NonDisparagement. Executive shall not disparage the
Employer or any of its shareholders, directors, officers, employees, or agents.
	 
	 	e.	 	Creative Works. Executive shall not create, assist
with or consult on any creative works which discuss, describe or reference
Employer or any executive of Employer. Creative works includes but is not
limited to novels, nonfiction writings, any authored work, plays, screenplays,
musicals or the like.

     7.3 DISPUTES OR CONTROVERSIES

     The Executive recognizes that should a dispute or controversy arising from or relating to this
Agreement be submitted for adjudication to any court, arbitration panel, or other third party, the
preservation of the secrecy of Confidential Information may be jeopardized. All pleadings,
documents, testimony, and records relating to any such adjudication will be maintained in secrecy
and will be available for inspection by the Employer, the Executive, and their respective attorneys
and experts, who will agree, in advance and in writing, to receive and maintain all such
information in secrecy, except as may be limited by them in writing.

12

 

8.
NON—COMPETITION AND NON—INTERFERENCE

     8.1 ACKNOWLEDGMENTS BY THE EXECUTIVE

     The Executive acknowledges that: (a) the services to be performed by him under this Agreement
are of a special, unique, unusual, extraordinary, and intellectual character; (b) the Employer’s
business is international in scope and its products are marketed throughout the United States and
the world; (c) the Employer competes with other businesses that are or could be located in any part
of the United States or the world; (d) the provisions of this Section 8 are reasonable and
necessary to protect the Employer’s business; and (e) in connection with the fulfillment of his
duties hereunder and as an employee of the Employer, the Employer will provide Executive with
Confidential Information necessitating the execution of the covenants contained in this Section 8.

     8.2 COVENANTS OF THE EXECUTIVE

     In consideration of the acknowledgments by the Executive, and in consideration of the
compensation and benefits to be paid or provided to the Executive by the Employer, the Executive
covenants that during and for eighteen months following the Employment Period he will not, directly
or indirectly:

	 	a.	 	except in the course of his employment hereunder, engage or
invest in, own, manage, operate, finance, control, or participate in the
ownership, management, operation, financing, or control of, be employed by,
associated with, or in any manner connected with, lend the Executive’s name or
any similar name to, lend Executive’s credit to or render services or advice
to, any business whose products or activities compete in whole or in part with
the products or activities of the Employer anywhere in the world, provided,
however, that the Executive may purchase or otherwise acquire up to (but not
more than) five percent (5%) of any class of securities of any enterprise (but
without otherwise participating in the activities of such enterprise) if such
securities are listed on any national or regional securities exchange or have
been registered under Section 12(g) of the Securities Exchange Act of 1934, as
amended;
	 
	 	b.	 	whether for the Executive’s own account or for the account of
any other person, solicit business of the same or similar type being carried on
by the Employer, from any person known by the Executive to be a customer or a
potential customer of the Employer, whether or not the Executive had personal
contact with such person during and by reason of the Executive’s employment
with the Employer;
	 
	 	c.	 	whether for the Executive’s own account or the account of any
other person, (i) solicit, employ, or otherwise engage as an employee,
independent contractor, or otherwise, any person who is an employee (or

13

 

	 	 	 	was an employee within two (2) years of the date in question) of the
Employer at any time during the Employment Period or in any manner induce or
attempt to induce any employee of the Employer to terminate his employment
with the Employer; or (ii) interfere with the Employer’s relationship with
any person, including any person who at any time during the Employment
Period was an employee, contractor, supplier, or customer of the Employer;
or

     If any covenant in this Section 8.2 is held to be unreasonable, arbitrary, or against public
policy, such covenant will be considered to be divisible with respect to scope, time, and
geographic area, and such lesser scope, time, or geographic area, or all of them, as a court of
competent jurisdiction may determine to be reasonable, not arbitrary, and not against public
policy, will be effective, binding, and enforceable against the Executive.

     The period of time applicable to any covenant in this Section 8.2 will be extended by the
duration of any violation by the Executive of such covenant.

9. GENERAL PROVISIONS

     9.1 INJUNCTIVE RELIEF AND ADDITIONAL REMEDY

     The Executive acknowledges that the injury that would be suffered by the Employer as a result
of a breach of the provisions of this Agreement (including any provision of Sections 7 and 8) would
be irreparable and that an award of monetary damages to the Employer for such a breach would be an
inadequate remedy. Consequently, the Employer will have the right, in addition to any other rights
it may have, to obtain injunctive relief to restrain any breach or threatened breach or otherwise
to specifically enforce any provision of this Agreement, and the Employer will not be obligated to
post bond or other security in seeking such relief.

     9.2 COVENANTS OF SECTIONS 7 AND 8 ARE ESSENTIAL AND INDEPENDENT COVENANTS

     The covenants by the Executive in Sections 7 and 8 are essential elements of this Agreement,
and without the Executive’s agreement to comply with such covenants, the Employer would not have
entered into this Agreement or employed the Executive. The Employer and the Executive have
independently consulted with their respective counsel and have been advised in all respects
concerning the reasonableness and propriety of such covenants, with specific regard to the nature
of the business conducted by the Employer.

     If the Executive’s employment hereunder expires or is terminated, this Agreement will continue
in full force and effect as is necessary or appropriate to enforce the covenants and agreements of
the Executive in Sections 7 and 8.

14

 

     9.3 REPRESENTATIONS AND WARRANTIES BY THE EXECUTIVE

     The Executive represents and warrants to the Employer that the execution and delivery by the
Executive of this Agreement do not, and the performance by the Executive of the Executive’s
obligations hereunder will not, with or without the giving of notice or the passage of time, or
both: (a) violate any judgment, writ, injunction, or order of any court, arbitrator, or
governmental agency applicable to the Executive; or (b) conflict with, result in the breach of any
provisions of or the termination of, or constitute a default under, any agreement to which the
Executive is a party or by which the Executive is or may be bound. The Executive further
specifically represents and warrants that he is not subject to, nor will he violate, any agreement
not to compete upon the execution and delivery by him of this Agreement.

     The Executive represents and warrants that he will not utilize or divulge any proprietary
materials or information from his previous employers and acknowledges that Employer has prohibited
Executive from bringing any such materials on to Employer’s premises and has advised Executive that
Executive’s failure to adhere to these prohibitions will subject Executive to immediate
termination.

     9.4 OBLIGATIONS CONTINGENT ON PERFORMANCE

     The obligations of the Employer hereunder, including its obligation to pay the compensation
provided for herein, are contingent upon the Executive’s performance of the Executive’s obligations
hereunder.

     9.5 WAIVER

     The rights and remedies of the parties to this Agreement are cumulative and not alternative.
Neither the failure nor any delay by either party in exercising any right, power, or privilege
under this Agreement will operate as a waiver of such right, power, or privilege, and no single or
partial exercise of any such right, power, or privilege will preclude any other or further exercise
of such right, power, or privilege or the exercise of any other right, power, or privilege. To the
maximum extent permitted by applicable law, (a) no claim or right arising out of this Agreement can
be discharged by one party, in whole or in part, by a waiver or renunciation of the claim or right
unless in writing signed by the other party; (b) no waiver that may be given by a party will be
applicable except in the specific instance for which it is given; and (c) no notice to or demand on
one party will be deemed to be a waiver of any obligation of such party or of the right of the
party giving such notice or demand to take further action without notice or demand as provided in
this Agreement.

personal, may not be delegated or assigned.

such other procedures as the parties may agree to at the time, before a
tribunal of three (3) arbitrators, one of which shall be selected by the
Executive, one of which shall be selected by the Employer, and the third of
which shall be selected by the two (2) arbitrators so selected. Any award
issued as a result of such arbitration shall be final and binding between the
parties, and shall be enforceable by any court having jurisdiction over the
party against whom enforcement is sought. A ruling by the arbitrators shall be
non-appealable. The parties agree to abide by and perform any award rendered
by the arbitrators. If either the Executive or Employer seeks enforcement of
the terms of this Agreement or seeks enforcement of any award rendered by the
arbitrators, then the prevailing party (designated by the arbitrators) to such
proceeding(s) shall be entitled to recover its costs and expenses (including
applicable travel expenses) from the non-prevailing party, in addition to any
other relief to which it may be entitled. If a dispute arises and one party
fails or refuses to designate an arbitrator within thirty (30) days after
receipt of a written notice that an arbitration proceeding is to be held, then
the dispute shall be resolved solely by the arbitrator designated by the other
party and such arbitration award shall be as binding as if three (3)
arbitrators had participated in the arbitration proceeding. Either the
Executive or the Employer may cause an arbitration proceeding to commence by
giving the other party notice in writing of such arbitration. Executive and
the Employer covenant and agree to act as expeditiously as practicable in order
to resolve all disputes by arbitration. Notwithstanding anything in this
section to the contrary, neither Executive nor the Employer shall be precluded
from seeking court action in the event the action sought is either injunctive
action, a

Agreement, no action may be brought in any court of law and EACH OF THE PARTIES
WAIVES ANY RIGHTS THAT IT MAY HAVE TO BRING A CAUSE OF ACTION IN ANY COURT OR
