         any Rule Change, the Lender may so notify the Borrower and require the
         Borrower, beginning fifteen (15) days after such notice, to pay it the
         amount necessary to restore its Return to what it would have been had

         loans, binding loan commitments and letters of credit.

                  (b) "L/C Rule" means any law, rule, regulation, guideline,

         reserves, special deposits or similar requirements against assets of,
         deposits with or for the account of, or credit extended by any Related

                  (d) "Return", for any period, means the percentage determined
         by dividing (i) the sum of interest and ongoing fees earned by the

         capital the Lender is required to maintain during such period as a
         result of its being a party to this Agreement, as determined by the
         Lender based upon its total capital requirements and a reasonable
         attribution formula that takes account of the Capital Adequacy Rules
         and L/C Rules then in effect, costs of issuing or maintaining any
         Advance or Letter of Credit and amounts received or receivable under
         this Agreement or the Note with respect to any Advance or Letter of
         Credit. Return may be calculated for each calendar quarter and for the
         shorter period between the end of a calendar quarter and the date of
         termination in whole of this Agreement.

                  (e) "Rule Change" means any change in any Capital Adequacy
         Rule or L/C Rule occurring after the date of this Agreement, or any
         change in the interpretation or administration thereof by any
         governmental or regulatory authority, but the term does not include any
         changes that at the Funding Date are scheduled to take place under the
         existing Capital Adequacy Rules or L/C Rules or any increases in the
         capital that the Lender is required to maintain to the extent that the
         increases are required due to a regulatory authority's assessment of
         that Lender's financial condition.

                  The initial notice sent by the Lender shall be sent as
         promptly as practicable after the Lender learns that its Return has
         been reduced, shall include a demand for payment of the amount
         necessary to restore the Lender's Return for the quarter in which the
         notice is sent, and shall state in reasonable detail the cause for the
         reduction in its Return and its calculation of the amount of such
         reduction. Thereafter, the Lender may send a new notice during each
         calendar quarter setting forth the calculation of the reduced Return
         for that quarter and including a demand for payment of the amount
         necessary to restore its Return for that quarter. The Lender's
         calculation in any such notice shall be conclusive and binding absent
         demonstrable error."

         6. Section 2.12 of the Credit Agreement is hereby amended and restated
in its entirety to read as follows:

                  "Section 2.12 Mandatory Prepayment. Without notice or demand,
         if the outstanding principal balance of the Revolving Advances plus the
         L/C Amount shall at any time exceed the Borrowing Base, the Borrower
         shall (i) first, immediately prepay the Revolving Advances to the
         extent necessary to eliminate such excess; and (ii) if prepayment in
         full of the Revolving Advances is insufficient to eliminate such
         excess, pay to the Lender in immediately available funds for deposit in
         the Special Account an amount equal to the remaining excess. Any
         payment received by the Lender under this Section 2.12 or under Section
         2.10 may be applied to the Obligations, in such order and in such
         amounts as the Lender, in its discretion, may from time to time
         determine; provided that any prepayment



                                      -5-



         under Section 2.10 which the Borrower designates as a partial
         prepayment of the Term Note or the CapEx Note, as the case may be,
         shall be applied to principal installments of the Term Note or the
         CapEx Note, as the case may be, in inverse order of maturity."

         7. The Credit Agreement is hereby amended by adding a new Section 2.17
to read as follows:

         "Section 2.17 Letters of Credit.

                  (a) The Lender agrees, on the terms and subject to the
         conditions herein set forth, to cause an Issuer to issue, from the
         Funding Date to the Termination Date, one or more irrevocable standby
         or documentary letters of credit (each, a "Letter of Credit") for the
         Borrower's account by guaranteeing payment of the Borrower's
         obligations or being a co-applicant. The Lender shall have no
         obligation to cause an Issuer to issue any Letter of Credit if the face
         amount of the Letter of Credit to be issued would exceed the lesser of:

                           (i) $250,000 less the L/C Amount, or

                           (ii) Availability.

                  Each Letter of Credit, if any, shall be issued pursuant to a
         separate L/C Application entered into between the Borrower and the
         Lender for the benefit of the Issuer, completed in a manner
         satisfactory to the Lender and the Issuer. The terms and conditions set
         forth in each such L/C Application shall supplement the terms and
         conditions hereof, but if the terms of any such L/C Application and the
         terms of this Agreement are inconsistent, the terms hereof shall
         control.

                  (b) No Letter of Credit shall be issued with an expiry date
         later than the Termination Date in effect as of the date of issuance.

                  (c) Any request to cause an Issuer to issue a Letter of Credit
         shall be deemed to be a representation by the Borrower that the
         conditions set forth in Section 4.2 have been satisfied as of the date
         of the request."

         8. The Credit Agreement is hereby amended by adding a new Section 2.18
to read as follows:

                  "Section 2.18 Special Account. If the Credit Facility is
         terminated for any reason while any Letter of Credit is outstanding,
         the Borrower shall thereupon pay the Lender in immediately available
         funds for deposit in the Special Account an amount equal to the L/C
         Amount. The Special Account shall be an interest bearing account
         maintained for the Lender by Wells Fargo Bank West N.A. Any interest
         earned on amounts deposited in the Special Account shall be credited to
         the Special Account. The Lender may apply amounts on deposit in the
         Special



                                      -6-



         Account at any time or from time to time to the Obligations in the
         Lender's sole discretion. The Borrower may not withdraw any amounts on
         deposit in the Special Account as long as the Lender maintains a
         security interest therein. The Lender agrees to transfer any balance in
         the Special Account to the Borrower when the Lender is required to
         release its security interest in the Special Account under applicable
         law."

         9. The Credit Agreement is hereby amended by adding a new Section 2.19
to read as follows:

                  "Section 2.19 Payment of Amounts Drawn Under Letters of
         Credit; Obligation of Reimbursement. The Borrower acknowledges that the
         Lender, as co-applicant, will be liable to the Issuer for reimbursement
         of any and all draws under Letters of Credit and for all other amounts
         required to be paid under the applicable L/C Application. Accordingly,
         the Borrower shall pay to the Lender any and all amounts required to be
         paid under the applicable L/C Application, when and as required to be
         paid thereby, and the amounts designated below, when and as designated:

                  (a) The Borrower shall pay to the Lender on the day a draft is
         honored under any Letter of Credit a sum equal to all amounts drawn
         under such Letter of Credit plus any and all reasonable charges and
         expenses that the Issuer or the Lender may pay or incur relative to
         such draw and the applicable L/C Application, plus interest on all such
         amounts, charges and expenses as set forth below (the Borrower's
         obligation to pay all such amounts is herein referred to as the
         "Obligation of Reimbursement").

                  (b) Whenever a draft is submitted under a Letter of Credit,
         the Borrower authorizes the Lender to make a Revolving Advance in the
         amount of the Obligation of Reimbursement and to apply the proceeds of
         such Revolving Advance thereto. Such Revolving Advance shall be
         repayable in accordance with and be treated in all other respects as a
         Revolving Advance hereunder.

                  (c) If a draft is submitted under a Letter of Credit when the
         Borrower is unable, because a Default Period exists or for any other
         reason, to obtain a Revolving Advance to pay the Obligation of
         Reimbursement, the Borrower shall pay to the Lender on demand and in
         immediately available funds, the amount of the Obligation of
         Reimbursement together with interest, accrued from the date of the
         draft until payment in full at the Default Rate. Notwithstanding the
         Borrower's inability to obtain a Revolving Advance for any reason, the
         Lender is irrevocably authorized, in its sole discretion, to make a
         Revolving Advance in an amount sufficient to discharge the Obligation
         of Reimbursement and all accrued but unpaid interest thereon.



                                      -7-



                  (d) The Borrower's obligation to pay any Revolving Advance
         made under this Section 2.19, shall be evidenced by the Revolving Note
         and shall bear interest as provided in Section 2.6."

         10. The Credit Agreement is hereby amended by adding a new Section 2.20
to read as follows:

                  "Section 2.20 Obligations Absolute. The Borrower's obligations
         arising under Section 2.19 shall be absolute, unconditional and
         irrevocable, and shall be paid strictly in accordance with the terms of
         Section 2.19, under all circumstances whatsoever, including (without
         limitation) the following circumstances:

                  (a) any lack of validity or enforceability of any Letter of
         Credit or any other agreement or instrument relating to any Letter of
         Credit (collectively the "Related Documents");

                  (b) any amendment or waiver of or any consent to departure
         from all or any of the Related Documents;

                  (c) the existence of any claim, setoff, defense or other right
         which the Borrower may have at any time, against any beneficiary or any
         transferee of any Letter of Credit (or any persons or entities for whom
         any such beneficiary or any such transferee may be acting), or other
         person or entity, whether in connection with this Agreement, the
         transactions contemplated herein or in the Related Documents or any
         unrelated transactions;

                  (d) any statement 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 whatsoever;

                  (e) payment by or on behalf of the Issuer under any Letter of
         Credit against presentation of a draft or certificate which does not
         strictly comply with the terms of such Letter of Credit; or

                  (f) any other circumstance or happening whatsoever, whether or
         not similar to any of the foregoing."

         11. Section 4.1 of the Credit Agreement is hereby amended by amending
