         2. Section 1.1(c)(iii) of Credit Agreement. Section 1.1 of the Credit
Agreement is hereby amended by replacing clause (c)(iii) in its entirety with
the following:

                  (i) Borrower shall repay the CapEx Loan in eight (8)

         Quarter, commencing on January 1, 2007 and continuing thereafter, the
         first two such installments to be equal to $250,000 and the last six
         such installments to be equal to the sum of (A) $250,000 plus (B)

         to each such CapEx Lender's respective CapEx Loan Commitment.

         3. Addition of Section 1.2A to Credit Agreement. The Credit Agreement

         1.2A Letters of Credit. Subject to and in accordance with the terms and
conditions contained herein and in Annex J, Borrower shall have the right to
request, and Revolving Lenders agree to incur, or purchase participations in,
Letter of Credit Obligations in respect of Borrower.

         4. Amendment to Section 1.3(a). Section 1.3 of the Credit Agreement is
hereby amended by replacing clause (a) of such Section in its entirety with the
following:

                  (a) Voluntary Prepayments; Reductions or Termination in
         Commitments. Borrower may at any time on at least five (5) days' prior
         written notice to Agent (i) voluntarily prepay all or part of the Term
         Loan or CapEx Loan, and/or (ii) permanently reduce or terminate the
         CapEx Loan Commitment and/or (iii) permanently reduce (but not
         terminate) the Revolving Loan Commitment; provided that (A) any such
         prepayments or reductions shall be in a minimum amount of $500,000 and
         integral multiples of $250,000 in excess of such amount, (B) the CapEx
         Loan Commitment shall not be reduced to an amount less than the amount
         of the CapEx Loan then outstanding and (C) the Revolving Loan
         Commitment shall not be reduced to an amount less than the aggregate
         amount of the Revolving Loan and Swing Line Loan then outstanding. In
         addition, Borrower may at any time on at least ten (10) days' prior
         written notice to Agent terminate the Revolving Loan Commitment;
         provided that upon such termination, all Loans and other Obligations
         shall be immediately due and payable in full, all Letter of Credit
         Obligations shall be cash collateralized or otherwise satisfied in
         accordance with Annex J hereto and all Commitments shall be terminated.
         Any voluntary prepayment of the Term Loan or CapEx Loan, any reduction
         or termination of the CapEx Loan Commitment and any termination of the
         Revolving Loan Commitment must be accompanied by payment of the Fee
         required by Section 1.9(d) plus the payment of any LIBOR funding
         breakage costs in accordance with Section 1.13(b). Upon any such
         reduction or termination of the Revolving Loan Commitment, Borrower's
         right to request Revolving Credit Advances, or request that Letter of
         Credit Obligations be incurred on its behalf, or request Swing Line
         Advances, shall simultaneously be permanently reduced or terminated, as
         the case may be; provided that a permanent reduction of the Revolving
         Loan Commitment shall not require a corresponding reduction in the L/C
         Sublimit except to the extent that the Revolving Loan Commitment is
         reduced below the L/C Sublimit. Upon any such reduction or termination
         of the CapEx Loan Commitment, Borrower's right to request CapEx
         Advances shall simultaneously be permanently reduced or terminated, as
         the case may be. Each notice of partial prepayment shall designate the
         Loans or other Obligations to which such prepayment is to be applied;
         provided that any partial prepayments of the Term Loan or CapEx Loan
         shall be applied to prepay the scheduled installments of the Term Loan
         or CapEx Loan, as the case may be, in inverse order of maturity.

         5. Amendment to Section 1.3(b)(i). Section 1.3 of the Credit Agreement
is hereby amended by replacing clause (b)(i) of such Section in its entirety
with the following:

                  (i) If at any time the aggregate outstanding balances of the
         Revolving Loan and the Swing Line Loan exceed the lesser of (A) the
         Maximum Revolver Amount and (B) the Borrowing Base, Borrower shall
         immediately repay the aggregate outstanding Revolving Credit Advances
         to the extent required to eliminate such excess. If any such excess
         remains after repayment in full of the aggregate outstanding Revolving
         Credit Advances, Borrower shall provide cash collateral for the Letter
         of Credit Obligations in the manner set forth in Annex J to the extent
         required to eliminate such excess. Notwithstanding the foregoing, any
         Overadvance made pursuant to Section 1.1(a)(iii) shall be repaid in
         accordance with Section 1.1(a)(iii).

         6. Amendment to Section 1.3(b)(vi). Section 1.3 of the Credit Agreement
is hereby further amended by replacing clause (b)(vi) of such Section in its
entirety with the following:

                  (vi) If any Credit Party issues any Stock (other than Stock
         contemplated to be issued in subsection (v) above) or any Debt at any
         time (other than Debt permitted to be incurred under Section 6.3), no
         later than the Business Day following the date of receipt of the cash
         proceeds thereof, Borrower shall prepay the Loans (and cash
         collateralize Letter of Credit Obligations) in an amount equal to all
         such cash proceeds, net of underwriting discounts and commissions and
         other reasonable costs paid to non-Affiliates in connection therewith.
         Any such prepayment shall be applied in accordance with Section 1.3(c).

         7. Amendment to Section 1.3(c). Section 1.3 of the Credit Agreement is
hereby further amended by replacing clause (c) of such Section in its entirety
with the following:

                  (c) Application of Certain Mandatory Prepayments. Any
         prepayments made by Borrower pursuant to Sections 1.3(b)(iv), (b)(v),
         (b)(vi) or (b)(vii) above shall be applied as follows: first, to Fees
         and reimbursable expenses of Agent then due and payable pursuant to any
         of the Loan Documents; second, to interest then due and payable on the
         Term Loan and CapEx Loan, pro rata between the Term Loan and CapEx
         Loan; third, to prepay the scheduled principal installments on the Term
         Loan and CapEx Loan, allocated pro rata between the Term Loan and CapEx
         Loan, and applied to principal installments in inverse order of
         maturity, until such Term Loan and CapEx Loan shall have been prepaid
         in full; and to the extent that any Event of Default has occurred and
         is continuing and the Requisite Revolving Lenders so elect, any
         remaining portion of such prepayments shall be applied as follows:
         fourth, to interest then due and payable on the Swing Line Loan; fifth,
         to the principal balance of the outstanding Swing Line Loan until the
         same has been repaid in full; sixth, to interest then due and payable
         on Revolving Credit Advances; seventh, to the principal balance of the
         outstanding Revolving Credit Advances until the same shall have been
         paid in full, and eighth, to any Letter of Credit Obligations, to
         provide cash collateral therefor in the manner set forth in Annex J,

                                       3
<PAGE>

         until all such Letter of Credit Obligations have been fully cash
         collateralized in the manner set forth in Annex J. The Revolving Loan
         Commitment shall be permanently reduced by the amount of any
         prepayments allocated as set forth in clauses fifth and seventh above,
         and to the extent that after giving effect to any such reduction in the
         Revolving Loan Commitment, the Swingline Commitment or the L/C Sublimit
         would exceed the Revolving Loan Commitment, the Swingline Commitment
         and/or the L/C Sublimit shall be reduced to the Revolving Loan
         Commitment. Promptly upon notice of, or receipt of any proceeds for,
         prepayment of the Loans under this Section 1.3(c), Agent shall notify
         the Lenders of the proposed allocation of such prepayment.
         Notwithstanding anything in this Section 1.3(c), each Lender shall have
         the right to waive any portion of the prepayment to be allocated to the
         principal amount of such Lender's Term Loan (if any) by notifying Agent
         of its election in writing no later than one Business Day after receipt
         of Agent's notice. Failure of a Lender to notify Agent of any waiver of
         such prepayment within such time period shall be deemed to be
         acceptance thereof. To the extent that (i) one or more Lenders waive
         all or any portion of any prepayment to be allocated to the principal
         amount of the Term Loans under this Section 1.3(c), or (ii) any
         proceeds remain after allocating any prepayment in the manner set forth
         above (collectively, the "Waived Prepayments"), such proceeds shall be
         retained by or returned to Borrower.

         8. Amendment to Section 1.5(a). Section 1.5 of the Credit Agreement is
hereby amended by replacing clause (a) of such Section in its entirety with the
following:

                  (a) Borrower shall pay interest to Agent, for the ratable
         benefit of Lenders, in accordance with the various Loans being made by
         each Lender, in arrears on each applicable Interest Payment Date, at
         the following rates: (i) with respect to the Revolving Credit Advances,
         the Index Rate plus the Applicable Revolver Index Margin per annum or,
         at the election of Borrower, the applicable LIBOR Rate plus the
         Applicable Revolver LIBOR Margin per annum, (ii) with respect to the
         Term Loan, the Index Rate plus the Applicable Term Loan Index Margin
         per annum or, at the election of Borrower, the applicable LIBOR Rate
         plus the Applicable Term Loan LIBOR Margin per annum, (iii) with
         respect to the CapEx Loan, the Index Rate plus the Applicable CapEx
         Loan Index Margin per annum or, at the election of Borrower, the
         applicable LIBOR Rate plus the Applicable CapEx Loan LIBOR Margin per
         annum, and (iv) with respect to the Swing Line Loan, the Index Rate
         plus the Applicable Revolver Index Margin per annum.

         As of the Closing Date, the Applicable Margins are as follows:


                   Applicable Revolver Index Margin                  0.75%

                  (d) So long as an Event of Default has occurred and is
         continuing under Section 8.1(a), (h) or (i), or so long as any other
         Default or Event of Default has occurred and is continuing and at the

hereby amended by replacing clause (a) of such Section in its entirety with the
following:

                  (a) So long as no Default or Event of Default has occurred and
         is continuing, (i) payments consisting of proceeds of Accounts received
         in the ordinary course of business shall be applied, first, to the
         Swing Line Loan and, second, to the Revolving Loan; (ii) payments
         matching specific scheduled payments then due shall be applied to those
         scheduled payments; (iii) voluntary prepayments shall be applied as
         determined by Borrower, subject to the provisions of Section 1.3(a);
         and (iv) mandatory prepayments shall be applied as set forth in

         against the Obligations as Agent may deem advisable notwithstanding any
         previous entry by Agent in the Loan Account or any other books and
         records. In the absence of a specific determination by Agent with

                  2.2 Further Conditions to Each Advance. Except as otherwise
         expressly provided herein, no Lender shall be obligated to fund any
         Advance, convert or continue any Loan as a LIBOR Loan or incur any
         Letter of Credit Obligation, if, as of the date thereof:

                  (a) (i) any representation or warranty by any Credit Party
         contained herein or in any other Loan Document is untrue or incorrect
         as of such date, except to the extent that such representation or

         therein expressly permitted or expressly contemplated by this Agreement
         and (ii) Agent or Requisite Revolving Lenders or Requisite CapEx
         Lenders, as the case may be, have determined not to make such Advance,
         convert or continue any Loan as LIBOR Loan or incur such Letter of
         Credit Obligation as a result of the fact that such warranty or
         representation is untrue or incorrect;

                  (b) any event or circumstance having a Material Adverse Effect
         has occurred since the date hereof as determined by the Requisite
         Revolving Lenders or Requisite CapEx Lenders, as the case may be, and
         Agent or Requisite Revolving Lenders or Requisite CapEx Lenders have
         determined not to make such Advance (or incur such Letter of Credit
         Obligation), convert or continue any Loan as a LIBOR Loan as a result
         of the fact that such event or circumstance has occurred;

                  (c) any Default or Event of Default has occurred and is
         continuing or would result after giving effect to any Advance (or the
         incurrence of any Letter of Credit Obligation), and Agent or Requisite
         Revolving Lenders or Requisite CapEx Lenders, as the case may be, shall
         have determined not to make any Advance, convert or continue any Loan
         as a LIBOR Loan as a result of that Default or Event of Default; or

                  (d) after giving effect to any Revolving Advance (or the
         incurrence of any Letter of Credit Obligation), the outstanding
         principal amount of the aggregate Revolving Loan would exceed the
         lesser of the Borrowing Base and the Maximum Revolver Amount, in each
         case, less the then outstanding principal amount of the Swing Line
         Loan.

         The request and acceptance by Borrower of the proceeds of any Advance,
         the incurrence of any Letter of Credit Obligations or the conversion or
         continuation of any Loan into, or as, a LIBOR Loan shall be deemed to
         constitute, as of the date thereof, (i) a representation and warranty
         by Borrower that the conditions in this Section 2.2 have been satisfied
         and (ii) a reaffirmation by Borrower of the granting and continuance of

         13. Amendment to Article 3. Article 3 of the Credit Agreement is hereby
amended by replacing the lead-in paragraph of such Article in its entirety with

                  To induce Lenders to make the Loans and to incur Letter of
         Credit Obligations, the Credit Parties executing this Agreement,
         jointly and severally, make the following representations and
         warranties to Agent and each Lender with respect to all Credit Parties,
         each and all of which shall survive the execution and delivery of this
         Agreement (it being understood and agreed that the representations and
         warranties made on the Closing Date are deemed to be made concurrently

         contemplated hereby):

         14. Amendment to Section 3.9. Section 3.9 of the Credit Agreement is
hereby amended by replacing such Section in its entirety with the following:

                  3.9 Government Regulation. No Credit Party 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. No Credit Party is subject to
         regulation under the Public Utility Holding Company Act of 1935, the
         Federal Power Act, or any other federal or state statute that restricts
         or limits its ability to incur Indebtedness or to perform its

         the incurrence of the Letter of Credit Obligations on behalf of
         Borrower, the application of the proceeds thereof and repayment thereof
         and the consummation of the Related Transactions will not violate any

         Obligations requested hereunder are made or incurred; (b) the
         disbursement of the proceeds of such Loans pursuant to the instructions
         of Borrower; (c) the Acquisition and the consummation of the other
         Related Transactions; and (d) the payment and accrual of all
         transaction costs in connection with the foregoing, each Credit Party
         is and will be Solvent.

         16. Amendment to Section 5.13(e). Section 5.13 of the Credit Agreement
is hereby amended by replacing clause (e) of such Section in its entirety with

         shall cause each other Credit Party to use its commercially reasonable
         efforts to deliver to the Agent a reasonably satisfactory landlord
         agreement from the lessor of the leased properties located at (i)
         Windwalker, 90 Reliance Road, Reliance, WY 82901 and (ii) 209 Kimberly,

         subordination of all Liens or claims that the landlord may assert

         exist any Indebtedness, except (without duplication) (i) Indebtedness
         secured by purchase money security interests and Capital Leases

         described in Disclosure Schedule (6.3) and refinancings thereof or
         amendments or modifications thereof that do not have the effect of
         increasing the principal amount thereof or changing the amortization
         thereof (other than to extend the same) and that are otherwise on terms
         and conditions no less favorable to any Credit Party, Agent or any
         Lender, as determined by Agent, than the terms of the Indebtedness
         being refinanced, amended or modified, (v) Permitted Insurance Premium
         Indebtedness in an aggregate amount not to exceed $3,500,000 at any one

hereby amended by replacing such Section in its entirety with the following:

                  6.7 Liens. No Credit Party shall create, incur, assume or
         permit to exist any Lien on or with respect to its Accounts or any of

         if such suspension occurred at their direction) so long as such Default
         or Event of Default is continuing. If any Default or Event of Default
         has occurred and is continuing, Agent may (and at the written request
         of Requisite Lenders shall), without notice except as otherwise

         all without presentment, demand, protest or further notice of any kind,
         all of which are expressly waived by Borrower and each other Credit
         Party; or (iii) exercise any rights and remedies provided to Agent
         under the Loan Documents or at law or equity, including all remedies
         provided under the Code; provided, that upon the occurrence of an Event
         of Default specified in Sections 8.1(h) or (i), the Commitments shall

         Borrowing Base, or that makes less restrictive the nondiscretionary
         criteria for exclusion from Eligible Accounts set forth in Section 1.6,
         shall be effective unless the same shall be in writing and signed by
         Agent, Requisite Revolving Lenders and Borrower. No amendment,
         modification, termination or waiver of or consent with respect to any
         provision of this Agreement that waives compliance with the conditions
         precedent set forth in Section 2.2 to the making of any Loan or the
         incurrence of any Letter of Credit Obligations shall be effective
         unless the same shall be in writing and signed by Agent, Requisite
         Revolving Lenders and Borrower. Notwithstanding anything contained in
         this Agreement to the contrary, no waiver or consent with respect to
         any Default or any Event of Default shall be effective for purposes of

         Revolving Lenders, Requisite Term Lenders or Requisite CapEx Lenders,
         respectively.

                             ANNEX J (SECTION 1.2A)
                                       TO
                                CREDIT AGREEMENT


                                LETTERS OF CREDIT

                  (a) Issuance. Subject to the terms and conditions of the
Agreement, Agent and Revolving Lenders agree to incur, from time to time prior
to the Commitment Termination Date, upon the request of Borrower and for
Borrower's account, Letter of Credit Obligations by causing Letters of Credit to
be issued by GE Capital or a Subsidiary thereof or a bank or other legally
authorized Person selected by or acceptable to Agent in its sole discretion
(each, an "L/C Issuer") for Borrower's account and guaranteed by Agent;
provided, that if the L/C Issuer is a Revolving Lender, then such Letters of
Credit shall not be guaranteed by Agent but rather each Revolving Lender shall,
subject to the terms and conditions hereinafter set forth, purchase (or be
deemed to have purchased) risk participations in all such Letters of Credit
issued with the written consent of Agent, as more fully described in paragraph
(b)(ii) below. The aggregate amount of all such Letter of Credit Obligations
shall not at any time exceed the least of (i) Two Million Dollars ($2,000,000)
(the "L/C Sublimit"), and (ii) the Maximum Amount less the aggregate outstanding
principal balance of the Revolving Credit Advances and the Swing Line Loan. No
such Letter of Credit shall have an expiry date that is more than one year
following the date of issuance thereof, unless otherwise determined by Agent in
its sole discretion (including with respect to customary evergreen provisions),
and neither Agent nor Revolving Lenders shall be under any obligation to incur
Letter of Credit Obligations in respect of, or purchase risk participations in,
any Letter of Credit having an expiry date that is later than the Commitment
Termination Date.

                  (b)(i) Advances Automatic; Participations. In the event that
Agent or any Revolving Lender shall make any payment on or pursuant to any
Letter of Credit Obligation, such payment shall then be deemed automatically to
constitute a Revolving Credit Advance under Section 1.1(a) of the Agreement
regardless of whether a Default or Event of Default has occurred and is
continuing and notwithstanding Borrower's failure to satisfy the conditions
precedent set forth in Section 2, and each Revolving Lender shall be obligated
to pay its Pro Rata Share thereof in accordance with the Agreement. The failure
of any Revolving Lender to make available to Agent for Agent's own account its
Pro Rata Share of any such Revolving Credit Advance or payment by Agent under or
in respect of a Letter of Credit shall not relieve any other Revolving Lender of
its obligation hereunder to make available to Agent its Pro Rata Share thereof,
but no Revolving Lender shall be responsible for the failure of any other
Revolving Lender to make available such other Revolving Lender's Pro Rata Share
of any such payment.

                     (ii) If it shall be illegal or unlawful for Borrower to
incur Revolving Credit Advances as contemplated by paragraph (b)(i) above
because of an Event of Default described in Sections 8.1(h) or (i) or otherwise
or if it shall be illegal or unlawful for any Revolving Lender to be deemed to
have assumed a ratable share of the reimbursement obligations owed to an L/C
Issuer, or if the L/C Issuer is a Revolving Lender, then (i) immediately and
without further action whatsoever, each Revolving Lender shall be deemed to have
irrevocably and unconditionally purchased from Agent (or such L/C Issuer, as the
case may be) an undivided interest and participation equal to such Revolving
Lender's Pro Rata Share (based on the Revolving Loan Commitments) of the Letter
of Credit Obligations in respect of all Letters of Credit then outstanding and
(ii) thereafter, immediately upon issuance of any Letter of Credit, each
Revolving Lender shall be deemed to have irrevocably and unconditionally
purchased from Agent (or such L/C Issuer, as the case may be) an undivided
interest and participation in such Revolving Lender's Pro Rata Share (based on
the Revolving Loan Commitments) of the Letter of Credit Obligations with respect
to such Letter of Credit on the date of such issuance. Each Revolving Lender
shall fund its participation in all payments or disbursements made under the
Letters of Credit in the same manner as provided in the Agreement with respect
to Revolving Credit Advances.

                                   Annex J - 1
<PAGE>

                  (c) Cash Collateral. (i) If Borrower is required to provide
cash collateral for any Letter of Credit Obligations pursuant to the Agreement,
including Section 8.2 of the Agreement, prior to the Commitment Termination
Date, Borrower will pay to Agent for the ratable benefit of itself and Revolving
Lenders cash or cash equivalents acceptable to Agent ("Cash Equivalents") in an
amount equal to 105% of the maximum amount then available to be drawn under each
applicable Letter of Credit outstanding. Such funds or Cash Equivalents shall be
held by Agent in a cash collateral account (the "Cash Collateral Account")
maintained at a bank or financial institution acceptable to Agent. The Cash
Collateral Account shall be in the name of Borrower and shall be pledged to, and
subject to the control of, Agent, for the benefit of Agent and Lenders, in a
manner satisfactory to Agent. Borrower hereby pledges and grants to Agent, on
behalf of itself and Lenders, a security interest in all such funds and Cash
Equivalents held in the Cash Collateral Account from time to time and all
proceeds thereof, as security for the payment of all amounts due in respect of
the Letter of Credit Obligations and other Obligations, whether or not then due.
The Agreement, including this Annex J, shall constitute a security agreement
under applicable law.

                  (ii) If any Letter of Credit Obligations, whether or not then
due and payable, shall for any reason be outstanding on the Commitment
Termination Date, Borrower shall either (A) provide cash collateral therefor in
the manner described above, or (B) cause all such Letters of Credit and
guaranties thereof, if any, to be canceled and returned, or (C) deliver a
stand-by letter (or letters) of credit in guarantee of such Letter of Credit
Obligations, which stand-by letter (or letters) of credit shall be of like tenor
and duration (plus thirty (30) additional days) as, and in an amount equal to
105% of the aggregate maximum amount then available to be drawn under, the
Letters of Credit to which such outstanding Letter of Credit Obligations relate
and shall be issued by a Person, and shall be subject to such terms and
conditions, as are be satisfactory to Agent in its sole discretion.

                  (iii) From time to time after funds are deposited in the Cash
Collateral Account by Borrower, whether before or after the Commitment
Termination Date, Agent may apply such funds or Cash Equivalents then held in
the Cash Collateral Account to the payment of any amounts, and in such order as
Agent may elect, as shall be or shall become due and payable by Borrower to
Agent and Lenders with respect to such Letter of Credit Obligations of Borrower
and, upon the satisfaction in full of all Letter of Credit Obligations of
Borrower, to any other Obligations then due and payable.

                  (iv) Neither Borrower nor any Person claiming on behalf of or
through Borrower shall have any right to withdraw any of the funds or Cash
Equivalents held in the Cash Collateral Account, except that upon the
termination of all Letter of Credit Obligations and the payment of all amounts
payable by Borrower to Agent and Lenders in respect thereof, any funds remaining
in the Cash Collateral Account shall be applied to other Obligations then due
and owing and upon payment in full of such Obligations any remaining amount
shall be paid to Borrower or as otherwise required by law. Interest earned on
deposits in the Cash Collateral Account shall be held as additional collateral.

                                   Annex J - 2
<PAGE>

                  (d) Fees and Expenses. Borrower agrees to pay to Agent for the
benefit of Revolving Lenders, as compensation to such Lenders for Letter of
Credit Obligations incurred hereunder, (i) all costs and expenses incurred by
Agent or any Lender on account of such Letter of Credit Obligations, and (ii)
for each month during which any Letter of Credit Obligation shall remain
outstanding, a fee (the "Letter of Credit Fee") in an amount equal to the
Applicable Revolver LIBOR Margin from time to time in effect multiplied by the
maximum amount available from time to time to be drawn under the applicable
Letter of Credit. Such fee shall be paid to Agent for the benefit of the
Revolving Lenders in arrears, on the first day of each month and on the
Commitment Termination Date. In addition, Borrower shall pay to any L/C Issuer,
on demand, such fees (including all per annum fees), charges and expenses of
such L/C Issuer in respect of the issuance, negotiation, acceptance, amendment,
transfer and payment of such Letter of Credit or otherwise payable pursuant to
the application and related documentation under which such Letter of Credit is
issued.

                  (e) Request for Incurrence of Letter of Credit Obligations.
Borrower shall give Agent at least two (2) Business Days' prior written notice
requesting the incurrence of any Letter of Credit Obligation. The notice shall
be accompanied by the form of the Letter of Credit (which shall be acceptable to
the L/C Issuer) and a completed Application for Standby Letter of Credit in the
form Exhibit B-1 attached hereto. Notwithstanding anything contained herein to
the contrary, Letter of Credit applications by Borrower and approvals by Agent
and the L/C Issuer may be made and transmitted pursuant to electronic codes and
security measures mutually agreed upon and established by and among Borrower,
Agent and the L/C Issuer.

                  (f) Obligation Absolute. The obligation of Borrower to
reimburse Agent and Revolving Lenders for payments made with respect to any
Letter of Credit Obligation shall be absolute, unconditional and irrevocable,
without necessity of presentment, demand, protest or other formalities, and the
obligations of each Revolving Lender to make payments to Agent with respect to
Letters of Credit shall be unconditional and irrevocable. Such obligations of
Borrower and Revolving Lenders shall be paid strictly in accordance with the
terms hereof under all circumstances including the following:

                  (i) any lack of validity or enforceability of any Letter of
         Credit or the Agreement or the other Loan Documents or any other
         agreement;

                  (ii) the existence of any claim, setoff, defense or other
         right that Borrower or any of its Affiliates or any Lender may at any
         time have against a beneficiary or any transferee of any Letter of
         Credit (or any Persons or entities for whom any such transferee may be
         acting), Agent, any Lender, or any other Person, whether in connection
         with the Agreement, the Letter of Credit, the transactions contemplated
         herein or therein or any unrelated transaction (including any
         underlying transaction between Borrower or any of its Affiliates and
         the beneficiary for which the Letter of Credit was procured);

                  (iii) any draft, demand, certificate or any other document
         presented under any Letter of Credit proving to be forged, fraudulent,
         invalid or insufficient in any respect or any statement therein being
         untrue or inaccurate in any respect;

                                   Annex J - 3
<PAGE>

                  (iv) payment by Agent (except as otherwise expressly provided
         in paragraph (g)(ii)(C) below) or any L/C Issuer under any Letter of
         Credit or guaranty thereof against presentation of a demand, draft or
         certificate or other document that does not comply with the terms of
         such Letter of Credit or such guaranty;

                  (v) any other circumstance or event whatsoever, that is
         similar to any of the foregoing; or

                  (vi) the fact that a Default or an Event of Default has
         occurred and is continuing.

                  (g) Indemnification; Nature of Lenders' Duties.

                  (i) In addition to amounts payable as elsewhere provided in
the Agreement, Borrower hereby agrees to pay and to protect, indemnify, and save
harmless Agent and each Lender from and against any and all claims, demands,
liabilities, damages, losses, costs, charges and expenses (including reasonable
attorneys' fees and allocated costs of internal counsel) that Agent or any
Lender may incur or be subject to as a consequence, direct or indirect, of (A)
the issuance of any Letter of Credit or guaranty thereof, or (B) the failure of
Agent or any Lender seeking indemnification or of any L/C Issuer to honor a
demand for payment under any Letter of Credit or guaranty thereof as a result of
any act or omission, whether rightful or wrongful, of any present or future de
jure or de facto government or Governmental Authority, in each case other than
to the extent as a result of the gross negligence or willful misconduct of Agent
or such Lender as finally determined by a court of competent jurisdiction.

                  (ii) As between Agent and any Lender and Borrower, Borrower
assumes all risks of the acts and omissions of, or misuse of any Letter of
Credit by beneficiaries of any Letter of Credit. In furtherance and not in
limitation of the foregoing, to the fullest extent permitted by law neither
Agent nor any Lender shall be responsible for: (A) the form, validity,
sufficiency, accuracy, genuineness or legal effect of any document issued by any
party in connection with the application for and issuance of any Letter of
Credit, even if it should in fact prove to be in any or all respects invalid,
insufficient, inaccurate, fraudulent or forged; (B) the validity or sufficiency
of any instrument transferring or assigning or purporting to transfer or assign
any Letter of Credit or the rights or benefits thereunder or proceeds thereof,
in whole or in part, that may prove to be invalid or ineffective for any reason;
(C) failure of the beneficiary of any Letter of Credit to comply fully with
conditions required in order to demand payment under such Letter of Credit;
provided, that in the case of any payment by Agent under any Letter of Credit or
guaranty thereof, Agent shall be liable to the extent such payment was made
solely as a result of its gross negligence or willful misconduct as finally
determined by a court of competent jurisdiction in determining that the demand
for payment under such Letter of Credit or guaranty thereof complies on its face
with any applicable requirements for a demand for payment under such Letter of
Credit or guaranty thereof; (D) errors, omissions, interruptions or delays in
transmission or delivery of any messages, by mail, cable, telegraph, telex or
otherwise, whether or not they may be in cipher; (E) errors in interpretation of
technical terms; (F) any loss or delay in the transmission or otherwise of any
document required in order to make a payment under any Letter of Credit or
guaranty thereof or of the proceeds thereof; (G) the credit of the proceeds of
any drawing under any Letter of Credit or guaranty thereof; and (H) any
consequences arising from causes beyond the control of Agent or any Lender. None
of the above shall affect, impair, or prevent the vesting of any of Agent's or
any Lender's rights or powers hereunder or under the Agreement.

                                   Annex J - 4
<PAGE>

                  (iii) Nothing contained herein shall be deemed to limit or to
expand any waivers, covenants or indemnities made by Borrower in favor of any
L/C Issuer in any letter of credit application, reimbursement agreement or
similar document, instrument or agreement between Borrower and such L/C Issuer,
including a Master Standby Agreement entered into with Agent.
