ARTICLE 2 THE LOANS Section 2.1 REVOLVING LOANS. Subject to the terms and conditions of this Agreement, each Lender hereby severally agrees during the period beginning on the date hereof and ending on the Revolving Loan Maturity Date to make revolving loans duly requested hereunder (the "Revolving Loans") to Borrowers in amounts equal to such Lender's Revolving Loan Pro Rata Share of each requested loan PROVIDED that, after giving effect to any requested loan, absent such Lender's consent, the aggregate of all Revolving Loans outstanding from such Lender will not exceed at any one time its Revolving Loan Pro Rata Share of the Total Revolving Loan Commitment. The Revolving Loans described in this Section constitute a revolving credit and within the amount and time specified, Borrowers may pay, prepay and reborrow. 11 Section 2.2 MANNER OF BORROWING. For each requested Loan, Borrowers shall deliver to Agent a Notice of Borrowing specifying the date of a requested Borrowing and the amount thereof. Borrowers may give a Notice of Borrowing on the same day it wishes a Loan to be made, provided said Notice of Borrowing is received by Agent no later than 11:00 a.m. (Seattle time) on the date of the requested borrowing. Each Notice of Borrowing shall be given in writing or orally and promptly confirmed in writing, provided, however, that Agent may rely on any oral Notice of Borrowing even if Agent does not receive a written confirmation. If Borrowers simultaneously elect to have interest accrue on a Revolving Loan at an Offshore Related Rate calculated by reference to LIBOR by giving an Interest Rate Notice described in Section 2.6(b) in respect of such borrowing, the Notice of Borrowing shall be given no later than 11:00 a.m. three Business Days prior to the date of the requested borrowing. Requests for borrowing, or confirmations thereof, received after the designated hour will be deemed received on the next succeeding Business Day. Each such Notice of Borrowing shall be irrevocable and shall be deemed to constitute a representation and warranty by Borrowers that as of the date of such notice the statements set forth in Article 4 are true and correct and that no Default or Event of Default has occurred and is continuing. Agent is authorized to make Loans upon the request of any person authorized in writing by the President or the CEO of the Northwest Pipe Company to make such requests. Each Loan requested by Borrowers under this Section shall be in an amount of not less than $100,000 and an integral multiple of $100,000. On receipt of a Notice of Borrowing, Agent shall promptly notify each Lender by telephone, telex or telefax of the date of the requested borrowing and the amount thereof. Each Lender shall before 1:00 p.m. (Seattle time) on the date of the requested borrowing, pay such Lender's Revolving Loan Pro Rata Share of the aggregate principal amount of the requested borrowing in immediately available funds to Agent at its Commercial Loan Processing Center in Seattle, Washington. Upon fulfillment to Agent's satisfaction of the applicable conditions set forth in Article 3, and after receipt by Agent of such funds, Agent will promptly make such funds available to Borrowers by depositing them to the ordinary checking account maintained by Borrowers with Agent. Section 2.3 AGENT'S RIGHT TO FUND. Unless Agent shall have received notice from a Lender prior to 12:00 Noon (Seattle time) on the date of any requested borrowing that such Lender will not make available to Agent its share of the requested borrowing, Agent may assume that such Lender has made such funds available to Agent on the date such Loan is to be made in accordance with Section 2.2 and Agent may, in reliance upon such assumption, make available to Borrowers on such date a corresponding amount. If and to the extent that such Lender shall not have so made such portion available to Agent, such Lender and Borrowers jointly and severally agree to pay to Agent forthwith on demand such corresponding amount, together with interest thereon for each day from the date such amount is made available to Borrowers until the date such amount is repaid to Agent, at (a) in the case of Borrowers, the Reference Related Rate and (b) in the case of such Lender, the Federal Funds Rate. Any such repayment by Borrowers shall be without prejudice to any rights it may have against the Lender that has failed to make available its funds for any requested borrowing. 12 Section 2.4 REPAYMENT OF PRINCIPAL. (a) On each day that the Total Utilization exceeds the Total Commitment, Borrowers shall repay Revolving Loans in such an amount as is necessary to reduce such Total Utilization to an amount equal to or less than the Total Commitment. If Borrowers shall pay any Offshore Related Rate Loan pursuant to this Section prior to the end of the Applicable Interest Period, Borrowers shall include with such payment any amount payable pursuant to Section 2.7 and applicable to the payment of such Offshore Related Rate Loan prior to the termination of the Applicable Interest Period. (b) Borrowers shall repay the principal amount of the Revolving Loans on or before the Revolving Loan Maturity Date. Section 2.5 OPTIONAL CONVERSION OF UP TO $10,000,000 OF REVOLVING LOANS. On the first day of any month, up to and including October 1, 1999, if at that time, the conditions set forth in Section 3.1 are satisfied, Borrowers may convert a portion of not less than $500,000 of the Revolving Loans in increments of $100,000 to a Term Loan, but Borrowers shall not convert more than a total of $10,000,000 of Revolving Loans to Term Loans. Each such conversion will be accomplished by Borrowers giving written notice to Agent at least 5 business days prior to the date selected by Borrowers for conversion. Such notice will specify what portions of the Term Loan will bear interest at the available alternative rates described in Section 2.6(b). Principal payments on each Term Loan will be paid in 16 equal consecutive quarterly installments with the first principal payment being due at the end of the calendar quarter following conversion. Interest on each Term Loan will be payable monthly in arrears. All then unpaid principal and interest on each Term Loan will be due and payable no later than 48 months following such conversion . Section 2.6 INTEREST ON LOANS. (a) GENERAL PROVISIONS. Borrowers agree to pay to Lenders interest on the unpaid principal amount of each Loan from the date of such Loan until such Loan shall be due and payable at a per annum rate equal to the Applicable Interest Rate in effect from time to time with respect to such Loan (or respective portions thereof). In addition, at Lenders' option, during any period of time while an Event of Default has occurred and is continuing, interest shall accrue and be paid on the unpaid principal amount of each Loan or portion thereof at a per annum rate equal to 3% above the Applicable Interest Rate for such Loan or portion thereof. Accrued but unpaid interest on each Loan or portion thereof shall be paid in arrears on the first business day of each calendar month, and at the applicable maturity date. (b) SELECTION OF ALTERNATIVE RATES. (1) Borrowers may, subject to the requirements of this Section, elect on any Business Day to have interest accrue on any Loan or any portion thereof at an Offshore Related Rate for an Applicable Interest Period. Borrowers may also, subject to the requirements of this Section, elect on any Business Day to have interest accrue on any Term Loan or portion thereof at a Long Term Rate for an Applicable Interest Period. Such notice (herein, an "Interest 13 Rate Notice") shall be deemed delivered when communicated to Agent (in the case of an oral notice) or when received by Agent (in the case of written notice) except that an Interest Rate Notice communicated to or received by Agent after the specified time on any Business Day, shall be deemed to have been delivered or received on the immediately succeeding Business Day. Any oral Interest Rate Notice shall be promptly confirmed in writing, provided, however, that Agent may rely on any oral Interest Rate Notice even if Agent does not receive a written confirmation. Such Interest Rate Notice shall identify, subject to the conditions of this Section, the Loan or portions thereof to accrue interest at the Offshore Related Rate or the Long Term Rate and the Applicable Interest Period which Borrowers select. Any such Interest Rate Notice shall be irrevocable and shall constitute a representation and warranty by Borrower that as of the date of such Interest Rate Notice, the statements set forth in Article 4 are true and correct and that no Default or Event of Default has occurred and is continuing. An Interest Rate Notice specifying a LIBOR rate shall be given before 11:00 a.m. (Seattle time) three Business Days prior to the commencement of the Applicable Interest Period. An Interest Rate Notice specifying an IBOR rate shall be given before 9:00 a.m. (Seattle time) on the date of commencement of the Applicable Interest Period. An Interest Rate Notice specifying a Long Term Rate given at the time of a conversion described in Section 2.5 shall be given concurrently with the notice of conversion after agreement on the rate has been reached, and the rate so agreed upon and specified in the Interest Rate Notice will be effective for the Applicable Interest Period. An Interest Rate Notice specifying a Long Term Rate which is given other than in connection with a conversion described in Section 2.5 shall be given before 9:00 a.m. (Seattle time) on the date of commencement of the Applicable Interest Period. Any Interest Rate Notice which specifies an Offshore Related Rate but fails to identify an Applicable Interest Period shall be deemed to request an Applicable Interest Period of one month. Any Interest Rate Notice which specifies a Long Term Rate but fails to identify an Applicable Interest Period shall be deemed to request an Applicable Interest Period of one year. (2) Borrowers' right to select the Offshore Related Rate or Long Term Rate to apply to a Loan or any portion thereof shall be subject to the following conditions: (i) the aggregate of all Loans, or portions thereof, to accrue interest at a particular Offshore Related Rate or Long Term Rate for the same Applicable Interest Period shall be an integral multiple of $100,000 and not less than $500,000; (ii) no such rate may be selected for any Revolving Loan, or Term Loan, or portion thereof, which is already accruing interest at an Offshore Related Rate or Long Term Rate unless such selection is only to become effective at the maturity of the Applicable Interest Period then in effect; (iii) no Lender shall have given notice pursuant to Section 2.6(d) that the selected Offshore Rate or Long Term Rate is not available; and (iv) no Default or Event of Default shall have occurred and be continuing. (3) In the absence of an effective request for the application of an Offshore Related Rate or Long Term Rate, the Revolving Loans, Term Loans or remaining portions thereof shall accrue interest at the Reference Related Rate. (4) The Interest Rate Notice may be given with and contained in any Notice of Borrowing. 14 (5) If Borrowers deliver an Interest Rate Notice with any Notice of Borrowing for a Loan and Borrowers thereafter declines to take such Loan or a condition precedent to the making of such Loan is not satisfied or waived, Borrowers shall indemnify Agent and each Lender for all losses and any costs which Agent or any Lender may sustain as a consequence thereof including, without limitation, the costs of re-employment of funds at rates lower than the cost to Lenders of such funds. Payment of the amount owed shall be due within fifteen (15) days after Borrowers' receipt of Agent's statement calculating the sum due. (c) APPLICABLE DAYS FOR COMPUTATION OF INTEREST. Computations of interest shall be made on the basis of a year of 360 days, for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest is payable. (d) UNAVAILABLE OFFSHORE RELATED RATE OR LONG TERM RATE. If any Lender reasonably determines that for any reason, fair and adequate means do not exist for establishing a particular Offshore Related Rate or Long Term Rate, or that an Offshore Related Rate or Long Term Rate will not adequately and fairly reflect the cost to it of making or maintaining the principal amount of a particular Offshore Related Rate Loan or Long Term Rate Loan or that accruing interest on any Offshore Related Rate Loan or Long Term Rate Loan has become unlawful or is contrary to any internal policies (of general application), such Lender may give notice of that fact to Agent and Borrowers. After such notice has been given and until such Lender notifies Borrowers and Agent that the circumstances giving rise to such notice no longer exist, the interest rate or rates so identified in such notice shall no longer be available. Any subsequent request by Borrowers to have interest accrue at such an Offshore Related Rate or Long Term Rate, as the case may be, shall be deemed to be a request for interest to accrue at the Reference Related Rate. If the circumstances giving rise to the notice described herein no longer exist, the Lender who had previously given notice of the unavailability of rate(s) shall notify Agent and Borrowers in writing of that fact, and Borrowers shall then once again become entitled to request that such Offshore Related Rate or Long Term Rate apply to the Loans in accordance with Section 2.6(b). (e) COMPENSATION FOR INCREASED COSTS. In the event that after the date hereof any change occurs in any applicable law, regulation, treaty or directive or interpretation thereof by any Governmental Authority charged with the administration or interpretation thereof, or any condition is imposed by any Governmental Authority after the date hereof or any change occurs in any condition imposed by any Governmental Authority on or prior to the date hereof which: (1) subjects any Lender to any Tax (other than any Tax measured by such Lender's net or gross income), or changes the basis of taxation of any payments to any Lender on account of principal of or interest on any Offshore Related Rate Loan or Long Term Rate Loan or fees in respect of such Lender's obligation to make Long Term Rate Loans or Offshore Related Rate Loans or other amounts payable with respect to such Loans; or (2) imposes, modifies or determines applicable any reserve, deposit or similar requirements against any assets held by, deposits with or for the account of, or loans or commitments by, the relevant office of any Lender in connection with its Long Term Rate Loans or Offshore Related Rate Loans to the extent the amount of which is in excess of, or was not 15 applicable at the time of computation of, the amounts provided for in the definition of such Long Term Rate or Offshore Related Rate; or (3) affects the amount of capital required or expected to be maintained by banks generally or corporations controlling banks and any Lender determines that the amount by which it or any corporation controlling it is required or expected to maintain or increase its capital is increased by, or based upon, the existence of this Agreement or of any Lender's Loans or Commitments hereunder; (4) imposes upon any Lender any other condition with respect to its Offshore Loans or its obligation to make Long Term Rate or Offshore Related Rate Loans; which, as a result thereof, (i) increases the cost to any Lender of making or maintaining its Loans or its Commitments hereunder, or (ii) reduces the net amount of any payment received by any Lender in respect of its Long Term Rate Loans or Offshore Related Rate Loans (whether of principal, interest, commitment fees or otherwise), or (iii) requires any Lender to make any payment on or calculated by reference to the gross amount of any sum received by it in respect of its Long Term Rate or Offshore Related Rate Loans, in each case by an amount which any such Lender in its reasonable judgment deems material, then and in any such case Borrowers shall pay to Agent for the account of such Lender on demand such amount or amounts as will compensate such Lender for any increased cost, deduction or payment actually incurred or made by such Lender, PROVIDED, HOWEVER, Borrowers shall not be obligated for amounts hereunder unless, within 60 days after learning thereof any such Lender shall have advised Borrowers of the subjection, change, requirement or other condition forming the basis for such Lender's request for additional payment hereunder. If Borrowers are advised of any such subjection, change, requirement or other condition prior to the expiration of an Applicable Interest Period for any Long Term Rate Loan or Offshore Related Rate Loan, Borrowers may elect to prepay the Long Term Rate Loan or Offshore Related Rate Loan, as applicable, without penalty or premium if such prepayment would reduce or eliminate the amounts which Borrowers would otherwise be obligated to pay any Lender under the terms of this Section. The demand for payment by any Lender shall be delivered to both Agent and Borrowers and shall state the subjection or change which occurred or the reserve or deposit requirements or other conditions which have been imposed upon such Lender or the request, direction or requirement with which it has complied, together with the date thereof, the amount of such cost, reduction or payment and the manner in which such amount has been calculated. The protection of this Section shall be available to each Lender regardless of any possible contention of invalidity or inapplicability of the relevant law, regulation, treaty, directive, condition or interpretation thereof. In the event that Borrowers pay any Lender the amount necessary to compensate such Lender for any charge, deduction or payment incurred or made by such Lender as provided in this Section, and such charge, deduction or payment or any part thereof is subsequently returned to such Lender as a result of the final determination of the invalidity or inapplicability of the relevant law, regulation, treaty, directive or condition, then such Lender shall remit to Borrowers the amount paid by Borrowers which has actually been returned to such Lender (together with any interest actually paid to such Lender on such returned amount), less such Lender's costs and expenses incurred in connection with such governmental regulation or any challenge made by such Lender with respect to its validity or applicability. 16 Section 2.7 PREPAYMENTS. Reference Related Rate Loans may be repaid at any time without penalty or premium. Except as provided in Section 2.6(e), if an Offshore Related Rate Loan or Long Term Rate Loan is paid prior to the end of the Applicable Interest Period, a fee computed in the manner set out in Schedule 1 shall be assessed and paid at the time of such payment. Such fee shall be calculated by Agent. Except as provided in Section 2.6(e), such fee shall apply in all circumstances where an Offshore Related Rate Loan or Long Term Rate Loan is paid prior to the end of the Applicable Interest Period, regardless of whether such payment is voluntary, mandatory (including, without limitation, payments required pursuant to Section 2.4) or the result of Agent's or any Lender's collection efforts. Section 2.8 MANNER OF PAYMENTS. (a) Agent is authorized to deduct all interest and all other fees and expenses due from any of Borrowers' checking accounts maintained with Agent. If such payments are not taken from Borrowers' checking accounts, all payments and prepayments of principal and interest on any Loan and all other amounts payable hereunder by Borrowers to Agent or any Lender shall be made by paying the same in United State Dollars and in immediately available funds to Agent at its Commercial Loan Processing Center, Seattle, Washington not later than 12:00 Noon (Seattle time) on the date on which such payment or prepayment shall become due. (b) Borrowers hereby authorizes Agent and each Lender, if and to the extent any payment is not promptly made pursuant to this Agreement or any other Loan Document, to charge from time to time against any or all of the accounts of Borrowers with Agent or any Lender or any Affiliate of any Lender any amount due hereunder or under such other Loan Document. (c) Whenever any payment hereunder or under any other Loan Document shall be stated to be due would otherwise occur on a day other than a Business Day, such payment shall be made on the next succeeding Business Day. In the case of an Offshore Loan or Long Term Base Loan, whenever the last day of any Applicable Interest Period would otherwise occur on a day other than a Business Day, the last day of such Applicable Interest Period shall occur, on the next succeeding Business Day and such extension of time shall in such case be included in the computation and payment of interest, UNLESS, such extension would cause the last day of such Applicable Interest Period to occur in the next following calendar month, in which case the last day of such Applicable Interest Period shall occur, on the preceding Business Day and the calculation of interest will be adjusted accordingly. Section 2.9 FEES. (a) Upon execution of this Agreement, Borrowers agree to pay Agent for the benefit of Lenders a fee of $7,500 to be divided equally between them. (b) Borrowers agree to pay Agent for the account of Lenders in proportion to their respective Revolving Loan Pro Rata Shares an Unused Commitment Fee. This fee will be payable quarterly in arrears on the last day of each calendar quarter, and will be computed by 17 multiplying the Unused Commitment Fee Rate, based upon a 360-day year by the daily amount by which the Total Revolving Loan Commitment exceeds the aggregate of the Revolving Loans. Section 2.10 SHARING OF PAYMENTS, ETC. If any Lender shall obtain any payment in respect of Borrowers' obligations under the Loan Documents (whether voluntary or involuntary, through the exercise of any right of set off or otherwise) in excess of the amount it would have received if all payments had been made directly to Agent and apportioned in accordance with the terms hereof, such Lender shall hold such excess payment in trust for Agent and Lenders and shall forthwith remit the same to Agent for Agent's Lenders' accounts as herein provided. Section 2.11 APPLICATION OF PAYMENTS. Any payment made by Borrowers in respect of amounts owing by them under any of the Loan Documents, in the absence of a continuing Event of Default shall be applied in the manner directed by Borrowers, and in the absence of such direction shall be applied as follows: (a) FIRST, to fees, expenses and indemnities due under any Loan Document; (b) SECOND, to interest due under provision of any Loan Document; (c) THIRD, to any principal payment then due under any Loan; (d) FOURTH, to prepay the principal amount of any Reference Rate Related Loan then outstanding but not yet due; and (e) FIFTH, to prepay the principal amount of any Offshore Related Rate Loan or Long Term Base Rate Related Loan then outstanding but not yet due.

In the absence of instructions from the Majority Lenders, Agent shall have authority (but not the obligation), in its sole discretion, to take or not to take any action, unless this Agreement specifically requires the consent of Lenders, and any such action or failure to act shall be binding on all Lenders. Each Lender shall execute and deliver such additional instruments, including powers of attorney in favor of Agent, as may be necessary or desirable to enable Agent to exercise its powers hereunder. Section 8.2 DUTIES AND OBLIGATIONS. (a) Neither 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 any of them under or in connection with this Agreement or any other Loan Document except for its or their own gross negligence or willful misconduct. Without limiting the generality of the foregoing, Agent (i) may treat each Lender which is a party hereto as the party entitled to receive payments hereunder until Agent receives written notice of the assignment of such Lender's interest herein signed by such Lender and made in accordance with the terms hereof and a written agreement of the assignee that it is bound hereby to the same extent as it would have been had it been an original party hereto, in each case in form satisfactory to Agent; (ii) may consult with legal counsel (including counsel for Borrowers), 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 experts; (iii) makes no warranty or representation to any Lender and shall not be responsible to any Lender for any statements, warranties or representations made in or in connection with this Agreement, any other Loan Document, or in any instrument or document furnished pursuant hereto or thereto; (iv) shall not have any duty to ascertain or to inquire as to the performance of any of the terms, covenants, or conditions of the Loan Documents, or of any instrument or document furnished pursuant thereto on the part of Borrowers or as to the use of the proceeds of any Loan or the proceeds received in respect of any Letter of Credit; (v) shall not be responsible to any Lender for the due execution, legality, validity, enforceability, genuineness, effectiveness, or value of this Agreement, of any other Loan Document, or of any instrument or document furnished pursuant hereto or thereto; and (vi) shall incur no liability under or in respect to this Agreement or any other Loan Document by acting upon any oral or written notice, consent, certificate or other instrument or writing (which may be by cable, telex or telefax) believed by it to be genuine and signed, sent or made by the proper party or parties or 34 by acting upon any representation or warranty of Borrowers made or deemed to be made in this Agreement or any other Loan Document. Agent may execute any of its duties under this Agreement or any other Loan Document by or through agents, employees or attorneys-in-fact and shall be entitled to advice of counsel concerning all matters pertaining to such duties. Agent shall not be responsible for the negligence or misconduct of any agent or attorney-in-fact that it selects with reasonable care. (b) Agent will promptly transmit to each Lender copies of all documents received from Borrowers pursuant to the requirements of this Agreement other than documents which by the terms of this Agreement, Borrowers are obligated to deliver directly to Lenders. (c) Each Lender or its assignee shall furnish to Agent in a timely fashion such documentation (including, but not limited to, IRS Forms Nos. W-8, 1001 and 4224) as may be reasonably requested by Agent to establish such Lender's status for tax withholding purposes. (d) Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default under any of the Loan Documents unless Agent has received written notice from a Lender or Borrowers referring to one or more of the Loan Documents, describing such Default or Event of Default and stating that such notice is a "notice of default." In the event that Agent receives such a notice, Agent shall promptly notify each Lender. Section 8.3 DEALINGS BETWEEN AGENT AND BORROWERS. With respect to its Commitment and the Loans made by it, Agent shall have the same rights, powers and responsibilities under this Agreement and the other Loan Documents as any other Lender and may exercise the same as though it were not Agent, and the term "Lender" as used herein and in the other Loan Documents shall unless otherwise expressly indicated include Agent in its Lender capacity. The limitations, disclaimers, waivers and the like set forth in Article 8 shall apply to the Agent solely in its capacity as Agent for Lenders, and not in its capacity as a Lender. Agent may accept deposits from, lend money to, act and generally engage in any kind of business with Borrowers and any person which may do business with Borrowers, all as if Agent were not Agent hereunder and without any duty to account therefor to Lenders. Section 8.4 LENDER CREDIT DECISION. Each Lender acknowledges that it has, independently and without reliance upon Agent or the other Lenders and based upon such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement and the other Loan Documents. Each Lender also acknowledges that it will, independently and without reliance upon Agent or the other Lenders and based upon 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 and the other Loan Documents. Section 8.5 INDEMNIFICATION. Lenders agree to indemnify Agent (to the extent not reimbursed by Borrowers) ratably according to their respective Funded Pro Rata Shares from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by or asserted against Agent in any way relating to or arising out of this Agreement or any other Loan Document or any action taken or omitted by Agent under this Agreement or 35 any other Loan Document, except any such as result from Agent's gross negligence or willful misconduct. Without limiting the foregoing, each Lender agrees to reimburse Agent promptly on demand in proportion to its Funded Pro Rata Share for any out-of-pocket expenses, including legal fees, incurred by Agent in connection with the administration or enforcement or preservation of any rights under any Loan Document (to the extent that Agent is not reimbursed for such expenses by Borrowers) including without limitation, expenses incurred in connection with any Letter of Credit. Section 8.6 SUCCESSOR AGENT. The Agent may, and at the request of the Majority Banks shall, resign as Agent upon 30 days' notice to the Banks. If the Agent resigns under this Agreement, the Majority Banks shall appoint from among the Banks a successor agent for the Banks which successor agent shall be approved by Borrowers. If no successor agent is appointed prior to the effective date of the resignation of the Agent, the Agent may appoint, after consulting with the Banks and Borrowers, a successor agent from among the Banks. Upon the acceptance of its appointment as successor agent hereunder, such successor agent shall succeed to all the rights, powers and duties of the retiring Agent and the term "Agent" shall mean such successor agent and the retiring Agent's appointment, powers and duties as Agent shall be terminated. After any retiring Agent's resignation hereunder as Agent, the provisions of this Article 8 and other applicable Sections of this Agreement shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under this Agreement. If no successor agent has accepted appointment as Agent by the date which is 30 days following a retiring Agent's notice of resignation, the retiring Agent's resignation shall nevertheless thereupon become effective and the Banks shall perform all of the duties of the Agent hereunder until such time, if any, as the Majority Banks appoint a successor agent as provided for above. Any company into which Agent may be merged or converted or with which it may be consolidated or any company resulting from any merger, conversion or consolidation to which it shall be a party or any company to which Agent may sell or transfer all or substantially all of its agency relationships shall be the successor to Agent without the execution or filing of any paper or further act, anything herein to the contrary notwithstanding. Section 8.7 INDEPENDENT DETERMINATION FOR FUNDING AND CLOSING. For purposes of determining compliance with the conditions specified in Section 3.1 each Lender that has executed this Agreement shall be deemed to have consented to, approved or accepted or to be satisfied with each document or other matter sent by the Agent to such Lender for consent, approval, acceptance or satisfaction, or required thereunder to be consented to or approved by or acceptable or satisfactory to the Lender. This Section is solely for the benefit of the Agent and not for the benefit of Borrowers or any other person. ARTICLE 9 LETTERS OF CREDIT Section 9.1 LETTERS OF CREDIT. Borrowers may request that Agent issue letters of credit for Borrowers' account in accordance with the terms and conditions of this Article. 36 Section 9.2 MANNER OF REQUESTING LETTERS OF CREDIT. (a) From time to time, Borrowers may request that Agent issue Standby or Commercial Letters of Credit for Borrowers' account or extend or renew any existing Letters of Credit. Such request will be made by delivering a written request for the issuance, extension or renewal of such a Letter of Credit to Agent. Each such request shall be deemed to constitute a representation and warranty by Borrowers that as of the date of such request, statements set forth in Article 4 are true and correct and that no Default or Event of Default has occurred and is continuing. Each such request shall specify the face amount of the requested Letter of Credit, the proposed date of expiration, the name of the intended beneficiary thereof, and whether such Letter of Credit is a Standby Letter of Credit or a Commercial Letter of Credit or an extension or renewal thereof. (b) Borrowers shall pay Agent for the account of Lenders such letter of credit fees calculated and payable in accordance with Agent's normal and customary practices for commercial letters of credit and shall pay 9/10ths of 1% per annum of the face amount of any Standby Letter of Credit. Borrowers shall be required to pay Agent only one-half of the letter of credit fee for certain standby letters of credit issued in favor of CIT Group/Business Credit, Inc., which guaranteed Dai-Ichi Kangyo Bank letters of credit replaced by Agent shortly prior to the date of this Agreement. The letter of credit fees shall be paid on issuance and annually thereafter. Each letter of credit requested hereunder shall be in a face amount such that after issuance of such letter of credit, the Total Utilization will not exceed the Total Revolving Loan Commitment. In addition, after such issuance, the Total Letter of Credit Usage must not exceed $6,000,000. Each Letter of Credit requested shall be issued with a maximum maturity of one year and shall have an expiration date not later than one year after the Revolving Loan Maturity Date. The maturity date for each Standby Letter of Credit may be automatically extended each year for an additional year unless the Agent gives Borrowers 45 days written notice to the contrary. (c) Borrowers shall execute a letter of credit application. Either as part of the application or as a separate document, Borrowers shall, at Agent's request, execute a reimbursement agreement, in the standard form then used by Agent, in respect of each Letter of Credit requested hereunder. Such reimbursement agreements may be amended from time to time, and are collectively referred to herein as the "Reimbursement Agreements". (d) Subject to the satisfaction of the conditions precedent set forth in Article 3 and Borrowers' compliance with the terms of this Section, Agent shall issue and deliver its letter of credit to Borrowers or to the designated beneficiary at such address as Borrowers may specify. New Letters of Credit and extensions or renewals of any existing Letters of Credit shall contain terms and conditions customarily included in Agent's letters of credit and shall otherwise be in a form acceptable to Agent. (e) Borrowers and Lenders have executed Pledge and Security Agreements dated May 27, 1998 with respect to certain Bonds supported by letters of credit governed by this Article 9. Such Pledge Agreements continue to be in force. 37 (f) In the event of any conflict between the terms of any Reimbursement Agreement or Letter of Credit and the terms of this Agreement, the terms of this Agreement shall control, unless Agent has otherwise agreed in a writing. Section 9.3 INDEMNIFICATION; INCREASED COSTS. Borrowers agree to indemnify Agent, and any Lender on demand for any and all additional costs, expenses, or damages reasonably incurred by such Agent or Lender, directly or indirectly, arising out of the issuance of any Letter of Credit or the purchase of any Letter of Credit Risk Participation, including, without limitation, any costs of maintaining reserves in respect thereof and any premium rates imposed by the Federal Deposit Insurance Corporation. If at any time after the date of this Agreement, the introduction of or any change in applicable law, rule or regulation or in the interpretation or administration thereof by any Governmental Authority charged with the interpretation of administration thereof, or compliance by Agent or Lender with any requests directed by such Governmental Authority (whether or not having the force of law) shall, with respect to any Letter of Credit or Letter of Credit Risk Participation, subject Agent or such Lender to any Tax or impose, modify or deem applicable any reserve, special deposit or similar requirements against the assets of, deposits with or for the account of Agent, or such Lender or shall impose on Agent or such Lender any other conditions affecting the Letters of Credit or Letter of Credit Risk Participations and the result of any of the foregoing is to increase the cost to Agent, or such Lender of issuing a Letter of Credit or holding a Letter of Credit Risk Participation or to reduce the amount of any sum received or receivable by Agent, or such Lender with respect to the Letters of Credit or Letter of Credit Risk Participations, then, upon demand by Agent, or such Lender, Borrowers shall pay to Agent or such Lender such additional amount or amounts as will compensate Agent, or such Lender for such increased cost or reduction. Borrowers agree to indemnify and hold Agent and Lenders (each, an "Indemnitee") harmless from and against any and all (a) Taxes payable in connection with Letters of Credit, Letter of Credit Risk Participations or the provisions of this Agreement relating thereto, and (b) actions, claims, damages, losses, liabilities, fines, penalties, costs, and expenses of every nature, including reasonable attorney's fees, suffered or incurred by the Indemnitee otherwise arising out of or relating to this Article, any Letter of Credit, or any Letter of Credit Risk Participations; PROVIDED, HOWEVER, said indemnification shall not apply to the extent that any such action, claim, damage, loss, liability, fine, penalty, cost or expense arises out of or is based solely upon the Indemnitee's willful misconduct or gross negligence. Section 9.4 PAYMENT BY BORROWERS. Borrowers agree to fully reimburse Agent for all amounts paid by Agent under, or in respect of, any Letter of Credit and to pay interest thereon at the Reference Related Rate then applicable to Revolving Loans from the date Agent makes such payment until the date of reimbursement pursuant to any demand for reimbursement by Agent. Such reimbursement shall be made in immediately available funds at Agent's Commercial Loan Processing Center not later than 11:00 a.m. (Seattle time) one day after Borrowers are first notified by Agent that Agent has made payment under the Letter of Credit. In addition, if Agent so elects pursuant to the terms of Section 7.2, following the occurrence of an Event of Default, the face amount of each Letter of Credit shall become immediately due and payable. If 38 Borrowers shall default in its obligations to reimburse Agent or make any other payment required hereunder, interest shall accrue on the unpaid amount thereof at a per annum rate equal to 3% above the Reference Related Rate changing as such Reference Related Rate changes from the date such amount becomes due and payable until payment in full by Borrower. Interest on such unpaid amounts shall be calculated on the basis of a year of 360 days and shall be payable on demand. Section 9.5 SALE OF RISK PARTICIPATIONS. Agent agrees to sell to each Lender (including itself), and each Lender severally agrees to unconditionally and irrevocably purchase from Agent, Letter of Credit Risk Participations. Each Letter of Credit Risk Participation sold hereunder shall be sold to Lenders in fractional amounts in proportion to their Revolving Loan Pro Rata Shares. Section 9.6 PROCEDURE FOR PARTICIPATIONS. Via telephone, telex, or facsimile, Agent will advise each Lender of its respective Loan Advance Pro Rata Share of each Letter of Credit on the same day Agent issues such Letter of Credit as requested by Borrowers pursuant to this Article. The notice shall contain the following information: (i) the face amount of the Letter of Credit issued, (ii) the number of Letter of Credit, (iii) the date of acceptance or issuance, (iv) the maturity or expiration date, and (v) the amount of such Lender's Revolving Pro Rata Share of any letter of credit fees received by Agent in respect of the Letter of Credit issued. Agent shall not have any duty to ascertain or to inquire as to the accuracy of the information furnished by Borrowers. Section 9.7 PAYMENT OBLIGATIONS. (a) REIMBURSEMENTS TO AGENT. In the event Borrowers fails to fully reimburse Agent for amounts disbursed under a Letter of Credit ("Letter of Credit Payment") by 12:00 Noon (Seattle time) on the date reimbursement is demanded, each Lender shall, upon receipt of notice from Agent of such failure, pay to Agent the amount of such Lender's Revolving Loan Pro Rata Share of the face amount of such Letter of Credit Payment, PROVIDED, HOWEVER, if Borrowers pay a portion but less than all of the face amount of any such Letter of Credit Payment, Lenders shall pay Agent only their respective Revolving Loan Pro Rata Shares of the difference between the face amount of the Letter of Credit Payment, as the case may be, and the amount paid by Borrowers on account of such Letter of Credit Payment. Each and every payment to be made by Lenders to Agent under this Section shall be made by federal wire transfer in immediately available funds. If any Lender receives notice from Agent by 1:00 p.m. (Seattle time) on any Business Day of its obligation to make payments under this subSection, then such Lender shall make such payment no later than 2:00 p.m. (Seattle time) on the day such notice is received. If any Lender receives such notice after 1:00 p.m. (Seattle time) on any Business Day, then such Lender shall make such payment by no later than 1:00 p.m. (Seattle time) on the next succeeding Business Day. If any Lender fails to make such payment by the date and time required, its obligation shall bear interest from and including the date when such payment was due until paid at the per annum rate equal to the Federal Funds Rate. (b) PAYMENTS TO LENDERS. Agent shall immediately remit to each Lender, via federal wire transfer of funds, such Lender's Revolving Loan Pro Rata Share of any principal, 39 interest, letter of credit fees or other amounts received from or for the account of Borrowers in respect of any Letter of Credit, PROVIDED, HOWEVER, Agent shall not remit to any Lender any amounts received from or for the account of Borrowers in payment of the face amount. In the event Agent is required to refund any amount which is paid to it or received by it from or for the account of Borrowers, then Lenders, to the extent they shall have previously received their Revolving Loan Pro Rata Share of such amount, agree to repay to Agent their respective Revolving Loan Pro Rata Shares of such amount.

Section 10.3 CROSS-DEFAULT. Any Event of Default under this Agreement shall be an event of default under any agreement with respect to the Secured Letter of Credit Facility. ARTICLE 11 MISCELLANEOUS Section 11.1 NO WAIVER; REMEDIES CUMULATIVE. No failure by Agent or any Lender to exercise, and no delay in exercising, any right, power or remedy under this Agreement or any other Loan Document shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or remedy under this Agreement or any other Loan Document preclude any other or further exercise thereof or the exercise of any other right, power, or remedy. The exercise of any right, power, or remedy shall in no event constitute a cure or waiver of any Event of Default this Agreement or any other Loan Document or prejudice the rights of Agent or Lenders in the exercise of any right hereunder or thereunder. The rights and remedies provided herein and therein are cumulative and not exclusive of any right or remedy provided by law. Section 11.2 GOVERNING LAW. This Agreement and the other Loan Documents shall be governed by and construed in accordance with the laws of the State of Oregon. Section 11.3 MANDATORY ARBITRATION.

The arbitration shall be conducted in accordance with the United States Arbitration Act (Title 9, U.S. Code), notwithstanding any 40 choice of law provision in this Agreement, and under the Commercial Rules of the AAA. The arbitrator(s) shall give effect to statutes of limitation in determining any claim. Any controversy concerning whether an issue is arbitrable shall be determined by the arbitrator(s). Judgment upon the arbitration award may be entered in any court having jurisdiction. No provision of this Section shall limit the right of any party to this Agreement to exercise self-help remedies such as set off, foreclosure against or sale of any collateral or security, or to obtain provisional or ancillary remedies from a court of competent jurisdiction before, after, or during the pendency of any arbitration or other proceeding. The exercise of any such remedy does not waive the right of either party to resort to arbitration. Section 11.4 NOTICES. All notices and other communications provided for in any Loan Document shall be in writing or (unless otherwise specified) by facsimile and shall be mailed (with first class postage prepaid) or sent or delivered to each party at the address or facsimile number set forth under its name on the signature page hereof, or at such other address as shall be designated by such party in a written notice to each other party.

Section 11.5 SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon and inure to the benefit of the parties and their respective Successors and assigns, PROVIDED that Borrowers may not assign or otherwise transfer all or any part of its rights or obligations hereunder or under any other Loan Document without the prior written consent of Agent and all Lenders. Except as provided in this Section or Section 11.7, no Lender shall have the right to sell or assign all or any portion of its Loans or of its right, title and interest therein or thereto or in or to any Loan Document to any other Person without Agent's and Borrowers' prior written consent and without providing Agent with a written agreement executed by such purchaser or assignee as provided in Section 8.2(a)(i). Borrowers' consent shall not be unreasonably withheld. Notwithstanding the foregoing, each Lender may grant participation, without consent, in all or any portion of its Loans and Commitment but such grant shall not entitle the participant to any direct rights against Borrowers under the terms of this Agreement or any other Loan Document. Any outright sale or assignment of a Lender's interest hereunder to another Lender must be to a commercial bank organized under the laws of the United States or any state thereof, having a combined capital and surplus of at least $100,000,000. Such sale made in conformance with the terms of this Section shall result in a corresponding adjustment to the selling and purchasing Lenders' Funded Pro Rata Share. Section 11.6 SEVERABILITY. Any provision of this Agreement or any other Loan Document which is prohibited or unenforceable in any jurisdiction shall as to such jurisdiction be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof or affecting the validity or enforceability of such provision in any 41 other jurisdiction. To the extent permitted by applicable law, the parties waive any provision of law which renders any provision hereof prohibited or unenforceable in any respect. Section 11.7 ADDITIONAL LENDERS. With Borrowers' prior written consent, which will not be unreasonably withheld, Bank of America may select one or more financial institutions to purchase a portion of the Loans and Commitment and become a Lender or Lenders under this Agreement, but such financial institution must be a commercial bank organized under the laws of the United States, or any state thereof, having a combined capital and surplus of at least $100,000,000. Upon such financial institution(s) executing a written agreement as provided in Section 8.2(a)(i), and delivery of a copy thereof to Borrowers, any such institution shall become a Lender with full rights as such and there shall be a corresponding adjustment to the Funded Pro Rata Share of Bank of America and such other Lender. Section 11.8 JOINT AND SEVERAL LIABILITY; REASON FOR EXECUTION. All liability of Borrowers hereunder is joint and several. Each Borrower is executing this Loan Agreement because each will receive working capital from the proceeds of the Loans. Loan proceeds will be allocated among Borrowers as they collectively agree. Section 11.9 SURVIVAL. The representations, warranties and indemnities of Borrowers in favor of Agent and Lenders shall survive indefinitely and, without limiting the foregoing, shall survive the execution and delivery of this Agreement, the Loan Documents and the other Loan Documents, the making of any Loans, the expiration of the Commitments and the repayment of all amounts due under the Loan Documents.

Brown 45 Schedule 1 PREPAYMENT FEES FOR OFFSHORE RELATED RATE LOANS The amount of the fee to be paid pursuant to Section 2.7 shall depend on the following: (1) The amount by which interest rates have changed between the Reference Date and the Prepayment Date. As used herein, "Reference Date" shall mean the first day of an Applicable Interest Period. As used herein, "Prepayment Date" shall mean the date Borrower either voluntarily or involuntarily prepays an Offshore Related Rate Loan. Certain U.S. Treasury rates are used as a benchmark to measure changes in interest rate levels. (a) A "reference rate" equal to the average interest rate yield at the Reference Date for U.S. Government Securities having maturities equivalent to that of the applicable Offshore Related Rate Loan will be determined in the manner described below for determining applicable rates but will be established as of the Reference Date for the Applicable Interest Period. This rate represents interest rate levels at the time a Loan is made or its interest rate fixed. (b) An "applicable rate," as determined as described below, represents interest rate levels as of the Prepayment Date. (2) The amount of principal prepaid. (3) A payment fee factor (see "payment fee factor schedule" below). This factor represents the economic loss to the Agent and Lenders resulting from a one dollar payment if rates were to drop by one percent from the time the rate was fixed. 46 CALCULATION OF PREPAYMENT FEES FOR OFFSHORE RELATED RATE LOANS If the reference rate is lower than or equal to the applicable rate, there is no payment fee. If the applicable rate is lower than the reference rate, the payment fee shall be equal to the difference between the reference rate and the applicable rate (expressed as a decimal), multiplied by the appropriate factor from the payment fee factor schedule, multiplied by the principal amount of the Offshore Related Rate Loan which is prepaid. EXAMPLE: An Offshore Related Rate Loan with principal of $850,000 is fully prepaid with 3 months remaining prior to the end of the Applicable Interest Period. A reference rate of 10% was assigned to the Offshore Related Rate Loan when the rate was fixed. The applicable rate (as determined by current 4-month U.S. Treasury rates) is 8.5%. Rates are therefore judged to have dropped by 1.5% since the rate was fixed, and a payment fee applies. A payment fee factor of .31 is determined from the tables below, and the payment fee is computed as follows: Payment Fee = (.10 - .085) x (.31) x ($850,000) = $3952.50 APPLICABLE RATES The applicable rate is equal to the average interest rate yield at the time of prepayment for U.S. Government Securities having maturities equivalent to the remaining portion of the Applicable Interest Period. The applicable rate shall be determined from the Federal Reserve Statistical Release (Publication H.15(519)) in the "This Week" (most recent week) column under the heading U.S. Government Securities - Treasury Bills - Secondary Market, interpolated to the nearest month. Rates listed in the Federal Reserve Statistical Release for maturities of less than one year are on a discount rate basis, and these rates shall be converted to a coupon equivalent basis, based upon a 360-day year. The Statistical Release published on Monday shall be used for calculation of payment fees payable on the following Tuesday through the following Monday, with appropriate adjustment if the day of publication changes. 47 PREPAYMENT FEE FACTOR SCHEDULES FOR OFFSHORE RELATED RATE LOANS MONTHS REMAINING IN THE APPLICABLE INTEREST PERIOD FOR OFFSHORE RELATED RATE LOANS 0 1 2 3 4 5 6 Factors 0 .10 .20 .31 .41 .51 .61 - -------------------- (1) If the remaining Applicable Interest Period or time prior to scheduled maturity is between any two time periods in the above schedules, interpolate between the corresponding factors. The Agent and the Lenders are not required to actually reinvest the paid principal in any U.S. Government Treasury obligations as a condition to receiving a payment fee as calculated above. 48 PREPAYMENT FEES FOR LONG TERM RATE LOANS The prepayment fee for Long Term Rate Loans will be the sum of fees calculated separately for each Prepaid Installment, as follows: (i) Agent will first determine the amount of interest which would have accrued each month for the Prepaid Installment had it remained outstanding until the applicable Original Payment Date, using the Long Term Rate; (ii) Agent will then subtract from each monthly interest amount determined in (i) above, the amount of interest which would accrue for that Prepaid Installment if it were reinvested from the date of prepayment through the Original Payment Date, using the Money Market Rate. (iii) If (i) minus (ii) for the Prepaid Installment is greater than zero, Agent will discount the monthly differences to the date of prepayment by the rate used in (ii) above. The sum of the discounted monthly differences is the prepayment fee for that Prepaid Installment. The following definitions will apply to the calculation of the prepayment fee for Long Term Rate Loans: "Money Market Rate" means the fixed interest rate per annum which Agent determines could be obtained by reinvesting a specified Prepaid Installment in the Money Market from the date of prepayment through the Original Payment Date. "Original Payment Dates" mean the date on which principal of the Long Term Rate Loan would have been paid if there had been no prepayment. If a portion of the principal would have been paid later than the end of the interest period in effect at the time of prepayment, then the Original Payment Date for that portion will be the last day of the interest period. "Prepaid Installment" means the amount of the prepaid principal of the Long Term Rate Loan which would have been paid on a single Original Payment Date. "Agent" may adjust the Money Market Rate to reflect the compounding, accrual basis, or other costs of the Long Term Rate Loan. Each of the rates is the Agent's estimate only and the Agent is under no obligation to actually reinvest any prepayment. The rates will be based on information from either the Telerate or Reuters information services, THE WALL STREET JOURNAL, or other information sources Agent deems appropriate. 49
