EXECUTION March 18, 1998 Osmonics, Inc. 5951 Clearwater Drive Minnetonka, Minnesota 55343 Re: Amended and Restated Credit Facility Ladies/Gentlemen: U.S. Bank National Association (d/b/a First Bank National Association), a national banking association ('First Bank'), or in its capacity as agent for the Banks described below, the 'Agent'), and Osmonics, Inc., a Minnesota corporation (the 'Borrower'), have heretofore entered into a letter Credit Agreement dated February 13, 1998 (the 'Existing Credit Agreement'). The Borrower's obligations to the Bank under the Existing Credit Agreement are further evidenced by a revolving note of the Borrower in favor of First Bank dated February 13, 1998, in the maximum principal amount of $20,000,000 (the 'Existing Revolving Note'), and a term note of the Borrower in favor of First Bank dated February 13, 1998, in the maximum principal amount of $35,000,000 (the 'Existing Term Note'). First Bank is pleased to advise Osmonics, Inc., a Minnesota corporation (the 'Borrower'), that First Bank, together with any other lenders that hereafter become parties hereto (individually, a 'Bank' and, collectively, the 'Banks'), is willing to make certain amendments to and to restate in its entirety the Existing Credit Agreement in this Amended and Restated Credit Agreement (the 'Agreement'), and to cause the Existing Revolving Note to be amended and restated in its entirety, to provide for a revolving credit facility in an amended aggregate amount not to exceed $30,000,000, all as further described herein. Capitalized terms used herein shall have the meanings set forth in Section 7. SECTION 1: ADVANCES, INTEREST AND FEES. 1.1 THE REVOLVING LOANS. Subject to the terms and conditions of this Agreement, each Bank severally agrees to make Revolving Loans ratably in proportion to such Bank's respective Revolving Commitment Amount as set forth on Schedule 1.1 hereto as its Revolving Commitment Amount to the Borrower until the earlier of March 31, 2003, or the date on which the Commitment is terminated as provided herein (such earlier date being the 'Termination Date'). The Banks shall not make any Revolving Loan if the aggregate outstanding principal amount of the Revolving Loans plus the Letter of Credit Obligations would exceed the Aggregate Revolving Commitment, as reduced as hereinafter provided. Each borrowing of Revolving Loans shall be shared ratably among the Banks. The Borrower may repay and reborrow. 1.2 PROCEDURE FOR REVOLVING LOANS. Any request by Borrower for Revolving Loans hereunder shall be in writing or by telephone and must be given so as to be received by the Agent not later than 11:00 a.m. (Minneapolis time) on the requested Revolving Loan Date if the request is for a Reference Rate Advance, or three Eurodollar Business Days prior to the Revolving Loan Date if the request is for a Eurodollar Advance. Each request for Revolving Loans hereunder shall specify (i) the requested Revolving Loan Date and (ii) the aggregate amount of Revolving Loans to be made on such date which shall be in a minimum amount of $250,000 or, if more, an integral multiple thereof. The Borrower hereby authorizes the Agent to rely upon the telephone or written instructions of any person identifying himself as an Authorized Officer and upon any signature which the Agent believes to be genuine, and the Borrower shall be bound thereby in the same manner as of such person were authorized or such signature were genuine. The Agent shall notify each other Bank promptly thereafter (Minneapolis time) on the date of receipt of the receipt of such request, the matters specified therein. On the date of the requested Revolving Loans, each Bank shall provide the amount of its Advance to the Agent in Immediately Available Funds not later than 1:00 p.m., Minneapolis time. Unless the Agent determines that any applicable condition specified in this Agreement has not been satisfied, the Agent will make available to the Borrower in Immediately Available Funds not later than 4:00 p.m. (Minneapolis time) on the requested Revolving Loan Date the amount of the requested Revolving Loans. If the Agent has made a Revolving Loan to the Borrower on behalf of a Bank but has not received the amount of such Revolving Loan from such Bank by the time herein required, such Bank shall pay interest to the Agent on the amount so advanced at the overnight Federal Funds rate from the date of such Revolving Loan to the date funds are received by the Agent from such Bank, such interest to be payable with such remittance from such Bank of the principal amount of such Revolving Loan (provided, however, that the Agent shall not make any Revolving Loan on behalf of a Bank if the Agent has received prior notice from such Bank that it will not make such Revolving Loan). If the Agent does not receive payment from such Bank by the next Business Day after the date of any Revolving Loan, the Agent shall be entitled to recover such Revolving Loan, with interest thereon at the rate then applicable to the such Revolving Loan, on demand, from the Borrower, without prejudice to the Agent's and the Borrower's rights against such Bank. 1.3 NOTES. The Revolving Loans of each Bank shall be evidenced by a single Revolving Note in the form of EXHIBIT A hereto, payable to the order of such Bank in a principal amount equal to such Bank's Revolving Commitment Amount originally in effect. Each Bank shall enter in its records the amount of its Revolving Loans, and the payments made thereon and such records shall be rebutted by presumptive evidence of the subject matters thereof. 1.4 CONVERSIONS AND CONTINUATIONS. On the terms and subject to the limitations hereof, the Borrower shall have the option at any time and from time to time to convert all or any portion of the Revolving Loans into Reference Rate Advances or Eurodollar Rate Advances, or to continue a Eurodollar Rate Advance as such; provided, however that a Eurodollar Rate Advance may be converted or continued only on the last day of the Interest Period applicable thereto, and no Advance may be converted to or continued as a Eurodollar Rate Advance if a Default or Event of Default has occurred and is continuing on the proposed date of continuation or conversion. Advances may be converted to, or continued as, Eurodollar Rate Advances only in integral multiples, as to the aggregate amount of the Advances of all Banks so converted or continued, of $250,000, or, in either case, if more, in integral multiples of $250,000 in excess thereof. The Borrower shall give the Agent written notice of any continuation or conversion of any Advances and such notice must be given so as to be received by the Agent not later than 12:00 noon (Minneapolis time) two Eurodollar Business Days prior to requested date of conversion or continuation in the case of the continuation of, or conversion to, Eurodollar Rate Advances and on the date of the requested continuation of, or conversion to, Reference Rate Advances. Each such notice shall specify (a) the amount to be continued or converted, (b) the date for the continuation or conversion, and (c) in the case of conversions to or continuations as Eurodollar Rate Advances, the Interest Period applicable thereto. Any notice given by the Borrower under this Section shall be irrevocable. If the Borrower shall fail to notify the Agent of the continuation of any Eurodollar Rate Advances within the time required by this Section, such Advances shall, on the last day of the Interest Period applicable thereto, automatically be converted into Reference Rate Advances of the same principal amount. All conversions and continuation of Advances must be made uniformly and ratably among the Banks. The number of Interest Periods for Eurodollar Rate Advances in effect at any one time shall not exceed ten. 1.5 INTEREST RATES, INTEREST PAYMENTS AND DEFAULT INTEREST. Interest shall accrue and be payable on the Loans as follows: (i) Subject to paragraph (iii) below, each Eurodollar Rate Advance shall bear interest on the unpaid principal amount thereof during the Interest Period applicable thereto at a rate per annum equal to the sum of (A) the Eurodollar Rate for such Interest Period, plus (B) the Applicable Margin. (ii) Subject to paragraph (iii) below, each Reference Rate Advance shall bear interest on the unpaid principal amount thereof at a varying rate per annum equal to the sum of (A) the Reference Rate, plus (B) the Applicable Margin. (iii) Any Advance which is not paid when due shall, at the option of the Majority Banks, bear interest until paid in full at the 'Default Rate,' which shall be (A) during the balance of any Interest Period applicable to an outstanding Eurodollar Rate Advance, a rate per annum equal to the sum of the rate applicable to such Advance during such Interest Period plus 2%, and (B) otherwise, a rate per annum equal to the sum of (1) the Reference Rate, plus (2) the Applicable Margin for Reference Rate Advances, plus (3) 2%. (iv) Interest shall be payable (A) with respect to each Eurodollar Rate Advance, on the last day of the Interest Period applicable thereto; (B) with respect to any Reference Rate Advance, on the last day of each month; (C) with respect to all Advances, upon any permitted prepayment (on the amount prepaid); and (D) with respect to all Advances, on the Termination Date; provided that interest under Section 1.6 (iii) shall be payable on demand. (v) Revolving Commitment Fees, Letter of Credit Fees and interest on Loans shall be computed on the basis of actual days elapsed and a year of 360 days. 1.6 COMMITMENT FEES. The Borrower shall pay to the Agent, for the account of each Bank, fees (the 'Revolving Commitment Fees') in an amount determined by applying the Applicable Fee Rate to the average daily Unused Revolving Commitment of such Bank for the period from the Closing Date to the Termination Date. Such Revolving Commitment Fees are payable in arrears quarterly on the last day of each quarter and on the Termination Date. 1.7 (a) OPTIONAL REDUCTION OR TERMINATION OF COMMITMENTS. The Borrower may, by written notice to the Agent, ratably reduce or terminate the Revolving Commitment Amounts, with any such reduction in a minimum amount of $1,000,000 or an integral multiple thereof. Upon any reduction in the Revolving Commitment Amounts pursuant to this Section, the Borrower shall pay to the Agent for the account of the Banks the amount, if any, by which the aggregate unpaid principal amount of outstanding Advances plus the Letter of Credit Obligations exceeds the reduced Commitment. Amounts so paid cannot be reborrowed. If the Commitment is terminated, the Borrower shall pay the full amount of all outstanding Advances, all accrued and unpaid interest and fees and all other unpaid obligations of the Borrower to the Bank hereunder. Notwithstanding the foregoing, the Revolving Commitments may not be reduced to an amount below outstanding Letter of Credit Obligations, or terminated if Letters of Credit are outstanding. (b) MANDATORY REDUCTION OF COMMITMENTS. If the closing of the Membrex Acquisition does not take place on or before May 29, 1998, the Revolving Commitment Amounts shall be ratably reduced by a total amount of $10,000,000. Upon mandatory reduction of the Revolving Commitment Amounts pursuant to this Section, the Borrower shall pay to the Agent for the account of the Banks the amount, if any, by which the aggregate unpaid principal amount of outstanding Revolving Loans plus the Letter of Credit Obligations exceeds the reduced Commitments. 1.8 PRINCIPAL REPAYMENT. The principal of the Revolving Loans shall be payable in full on the Termination Date. If any Letters of Credit are outstanding on the Termination Date, the Borrower shall immediately deposit into the Holding Account an amount equal to the maximum amount then available to be drawn under such Letters of Credit. 1.9 PAYMENTS. Payments and pre-payments of principal, interest, fees and expenses hereunder and under the Revolving Note shall be made without set-off or counterclaim in immediately available funds not later than 2:00 p.m., Minneapolis time, on the dates called for under this Agreement at the main office of the Agent in Minneapolis, Minnesota. Funds received on any day after such time shall be deemed to have been received on the next business day. The Agent will promptly distribute in like funds to each Bank its ratable share of each payment of principal, interest, Revolving Commitment Fees and Letter of Credit Fees. Whenever any payment would be due on a day which is not a business day, such payment shall be made on the next succeeding business day and such extension of time shall be included in the computation of any interest or fees. 1.10 OPTIONAL PREPAYMENTS. The Borrower may prepay the Revolving Loans, in whole or in part, at any time, without premium or penalty. Each partial prepayment of Revolving Loans shall be in an aggregate amount for all the Banks of $1,000,000 or an integral multiple thereof. Amounts prepaid on the Revolving Loans may be reborrowed subject to the terms conditions of this Agreement. Amounts paid or prepaid on the Loans shall be for the account of each Bank in proportion to its share of such Loans. 1.11 LETTERS OF CREDIT. Upon the terms and subject to the conditions of this Agreement, the Agent agrees to issue Letters of Credit for the account of the Borrower from time to time between the Closing Date and the Termination Date in such amounts as the Borrower shall request up to an aggregate amount at any time outstanding not exceeding $10,000,000; subject to the satisfaction of the Agent with the form, substance and beneficiary of each such Letter of Credit, and the absence of any statutory or regulatory change or directive affecting the issuance by the Agent of letters of credit, and provided that no Letter of Credit will be issued in any amount which, after giving effect to such issuance, would cause Total Revolving Outstandings to exceed the Aggregate Revolving Commitment. Letters of Credit shall be issued in support of obligations of the Borrower incurred in the ordinary course of the Borrower's business. No Letter of Credit may have a term longer than twenty-four months, and the aggregate amount available to be drawn under all Letters of Credit with a remaining term longer than twelve months shall not exceed $5,000,000. 1.12 PROCEDURES FOR LETTERS OF CREDIT. Each request for a Letter of Credit shall be made by the Borrower in writing, by telex, facsimile transmission or electronic conveyance received by the Agent by 2:00 p.m., Minneapolis time, on a Business Day which is not less than two Business Days prior to the requested date of issuance (which shall also be a Business Day). The Agent may require that such request be made on such letter of credit application and reimbursement agreement form as the Agent may from time to time specify, along with satisfactory evidence of the authority and incumbency of the officials of the Borrower making such request. The Agent shall promptly notify the other Banks of the receipt of the request and the matters specified therein. On the date of each issuance of a Letter of Credit the Agent shall send notice to the other Banks of such issuance. 1.13 AGREEMENT TO REPAY LETTER OF CREDIT DRAWINGS. If the Agent has determined to pay a drawing on any Letter of Credit, it will notify the Borrower of that fact. The Borrower shall reimburse the Agent by 10:00 a.m. (Minneapolis time) on the day on which such drawing is to be paid in Immediately Available Funds in an amount equal to the amount of such drawing. 1.14 OBLIGATIONS ABSOLUTE. The obligations of the Borrower to repay the Agent for any amount drawn on any Letter of Credit shall be absolute, unconditional and irrevocable, shall continue for so long as any Letter of Credit is outstanding notwithstanding any termination of this Agreement, and shall be paid strictly in accordance with the terms of this Agreement, under all circumstances whatsoever, including without limitation the following circumstances: (a) Any lack of validity or enforceability of any Letter of Credit; (b) The existence of any claim, setoff, defense or other right which the Borrower may have or claim at any time against any beneficiary, transferee or holder of any Letter of Credit (or any Person for whom any such beneficiary, transferee or holder may be acting), the Agent or any Bank or any other Person, whether in connection with a Letter of Credit, this Agreement, the transactions contemplated hereby, or any unrelated transaction; or (c) 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. Neither the Agent nor any Bank nor officers, directors or employees of any thereof shall be liable or responsible for, and the obligations of the Borrower to the Agent and the Banks shall not be impaired by: (i) The use which may be made of any Letter of Credit or for any acts or omissions of any beneficiary, transferee or holder thereof in connection therewith; (ii) The validity, sufficiency or genuineness of documents, or of any endorsements thereon, even if such documents or endorsements should, in fact, prove to be in any or all respects invalid, insufficient, fraudulent or forged; (iii) The acceptance by the Agent of documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary; or (iv) Any other action of the Agent in making or failing to make payment under any Letter of Credit if in good faith and in conformity with U.S. or foreign laws, regulations or customs applicable thereto. Notwithstanding the foregoing, the Borrower shall have a claim against the Agent, and the Agent shall be liable to the Borrower, to the extent, but only to the extent, of any direct, as opposed to consequential, damages suffered by the Borrower which the Borrower proves were caused by the Agent's willful misconduct or gross negligence in determining whether documents presented under any Letter of Credit comply with the terms thereof. 1.15 LOANS TO COVER UNPAID DRAWINGS. Whenever any amount drawn under a Letter of Credit is not repaid by the Borrower as required in Section 1.14, the Agent shall give the other Banks notice to that effect, specifying the amount thereof, in which event each Bank is authorized (and the Borrower does hereby so authorize each Bank) to, and shall, make a Revolving Loan (as a Reference Rate Advance) to the Borrower in an amount equal to such Bank's ratable share of the amount of the unpaid drawing. The Agent shall notify each Bank by 12:00 noon (Minneapolis time) of the amount of the Revolving Loan to be made by such Bank. Each Bank shall then make such Revolving Loan (regardless of noncompliance with the applicable conditions precedent specified in this Agreement hereof and regardless of whether an Event of Default then exists) and each Bank shall provide the Agent with the proceeds of such Revolving Loan in Immediately Available Funds, at the office of the Agent, not later than 2:00 p.m. (Minneapolis time) on the day on which such Bank received such notice. The Agent shall apply the proceeds of such Revolving Loans directly to reimburse itself for such unpaid drawing. If any portion of any such amount paid to the Agent should be recovered by or on behalf of the Borrower from the Agent in bankruptcy, by assignment for the benefit of creditors or otherwise, the loss of the amount so recovered shall be ratably shared between and among the Banks in the manner contemplated by Section 6.9 hereof. If for any reason any Bank is unable to make a Revolving Loan to the Borrower to reimburse the Agent for an unpaid drawing, then such Bank shall immediately purchase from the Agent a risk participation in such unpaid drawing, at par, in an amount equal to such Bank's ratable share of the unpaid drawing (before deducting the amount of any Revolving Loans made by other Banks to reimburse the Agent for such Unpaid Drawing). Each Bank shall pay to the Agent, not later than 2:00 P.M. (Minneapolis time) on the date it receives such notice, such Bank's ratable share of such unpaid drawing. 1.16 LETTER OF CREDIT FEES. For each Letter of Credit issued, the Borrower shall pay to the Agent for the account of the Banks, in advance payable on the date of issuance, a fee (a 'Letter of Credit Fee') in an amount determined by applying a per annum rate equal to the Applicable Margin for Eurodollar Rate Advances in effect on such date to the original face amount of a Letter of Credit, for the period from the date of issuance to the scheduled expiration date of such Letter of Credit; provided that for Performance Letters of Credit, if the Applicable Margin for Eurodollar Rate Advances exceeds one percent (1%), the rate for calculation of such fee shall be one percent (1%). In addition to the Letter of Credit Fee, the Borrower shall pay to the Agent, for its own account, on demand, all issuance, amendment, drawing and other fees regularly charged by the Agent to its letter of credit customers and all out-of-pocket expenses incurred by the Agent in connection with the issuance, amendment, administration or payment of any Letter of Credit. 1.17 FUNDING LOSSES; EURODOLLAR RATE ADVANCES. The Borrower shall indemnify the Banks against any loss or expense which the Banks may sustain: (a) if for any reason, other than a default by such Bank, a funding of a Eurodollar Rate Advance does not occur on the date specified therefor in the Borrower's request or notice as to such advance, or (b) if any payment of any Eurodollar Advance occurs on a date other than the last day of the Interest Period thereof. 1.18 ILLEGALITY. If any Regulatory Change shall make it unlawful or impossible for any Bank to make, maintain or fund any Eurodollar Rate Advances, such Bank shall notify the Borrower and the Agent, whereupon all of the affected Advances shall be automatically converted to Reference Rate Advances as of the date of such Bank's notice, and upon such conversion the Borrower shall indemnify such Bank in accordance with Section 1.18. 1.19 INTEREST RATE NOT ASCERTAINABLE, ETC. If, on or prior to the date for determining the Adjusted Eurodollar Rate in respect of the Interest Period for any Eurodollar Rate Advance, any Bank reasonably determines (which determination shall be presumptively correct) that deposits in dollars (in the applicable amount) are not being made available to such Bank in the relevant market for such Interest Period, or the Adjusted Eurodollar Rate will not adequately and fairly reflect the cost to such Bank of funding or maintaining Eurodollar Rate Advances for such Interest Period, such Bank shall forthwith give notice to the Borrower and the other Banks of such determination, whereupon the obligation of such Bank to make or continue, or to convert any Advances to, Eurodollar Rate Advance shall be suspended until such Bank notifies the Borrower and the Agent that the circumstances giving rise to such suspension no longer exist. Each Bank shall promptly notify the Borrower and the Agent when the circumstances giving rise to any such suspension no longer exist. While any such suspension continues, all further Advances by such Bank shall be made as Reference Rate Advances. 1.20 INCREASED COST. If any Regulatory Change shall subject any Bank to any tax, duty or other charge with respect to its Eurodollar Rate Advances, the Letters of Credit, its Notes or its obligation to make Eurodollar Rate Advances or to make Revolving Loans to repay, or purchase participations in, drawings under Letters of Credit, or shall change the basis of taxation of payment to any Bank of the principal of or interest on its Eurodollar Rate Advances or such Revolving Loans or participations, or any other amounts due under this Agreement in respect thereof (except for changes in the rate of tax on the overall net income of such Bank or its Applicable Lending Office imposed by the jurisdiction in which such Bank's principal office or Applicable Lending Office is located); or shall impose, modify or deem applicable any reserve, special deposit, capital requirement or similar requirement (including, without limitation, any such requirement imposed by the Board, but excluding with respect to any Eurodollar Rate Advance any such requirement to the extent included in calculating the applicable Adjusted Eurodollar Rate) against assets of, deposits with or for the account of, or credit extended by, any Bank or shall impose on any Bank or the interbank Eurodollar market any other condition affecting its Eurodollar Rate Advances, the Letters of Credit, its Notes, or its obligation to make Eurodollar Rate Advances or to make Revolving Loans to repay, or purchase participations in, drawings under Letters of Credit, and the result of any of the foregoing is to increase the cost to such Bank, or to reduce the amount of any sum received or receivable by such Bank under this Agreement or under its Notes, then, within 10 days after demand by such Bank (with a copy to the Agent), the Borrower shall pay to such Bank such additional amount or amounts as will compensate such Bank for such increased cost or reduction. A certificate of any Bank claiming compensation under this Section, setting forth the additional amount or amounts to be paid to it hereunder and stating in reasonable detail the basis for the charge and the method of computation, shall be conclusive in the absence of error. In determining such amount, any Bank may use any reasonable averaging and attribution methods. Failure on the part of any Bank to demand compensation for any increased costs or reduction in amounts received or receivable with respect to any Interest Period shall not constitute a waiver of such Bank's rights to demand compensation for any increased costs or reduction in amounts received or receivable in any subsequent Interest Period. If a Regulatory Change with respect to which a Bank has demanded compensation hereunder is subsequently terminated or repealed, or the costs imposed on a Bank as a result of a change are subsequently reduced due to an amendment thereof, such Bank shall only be entitled to compensation hereunder to the extent of the increased costs incurred as a result of such Regulatory Change prior to the date such Regulatory Change no longer imposes costs on such Bank, or to reduced compensation from and after the date the amendment of such Regulatory Change reduces the costs incurred by such Bank. SECTION 2: CONDITIONS PRECEDENT 2.1 CONDITIONS OF INITIAL LOANS. The making of the initial Loans and the issuance of the initial Letter of Credit hereunder shall be subject to the prior simultaneous satisfaction of the following conditions precedent: (a) The closing of the ReliaStar Indebtedness shall have occurred; (b) The amount of the Term Loan under the Existing Credit Agreement outstanding as of the date hereof shall have been repaid in full; (c) The Agent shall have received the following in sufficient counterparts (except for the Notes) for each Bank: (i) Executed counterparts of this Agreement, duly executed by the Borrower and the Banks; (ii) A Revolving Note drawn to the order of each Bank executed by a duly authorized officer (or officers) of the Borrower and dated the Closing Date.

To the best of the Borrower's knowledge, the audited financial statements of Micron as at October 31, 1997, as heretofore furnished to the Banks, have been prepared in accordance with GAAP on a consistent basis and fairly present the financial condition of Micron as at such date and the results of its operations and cash flow for the fiscal year then ended.

Neither the Agent nor any of its directors, officers or employees shall be liable for any action taken or omitted to be taken by it under or in connection with the Loan Documents, except for its own gross negligence or willful misconduct. The Agent shall act as an independent contractor in performing its obligations as Agent hereunder and nothing herein contained shall be deemed to create any fiduciary relationship among or between the Agent, the Borrower or the Banks. 6.2 CONSULTATION WITH COUNSEL.

Each Bank has made, and shall continue to make, its own independent investigation or evaluation of the operations, business, property and condition, financial and otherwise, of the Borrower in connection with entering into this Agreement and has made its own appraisal of the creditworthiness of the Borrower. Except as explicitly provided herein, the Agent has no duty or responsibility, either initially or on a continuing basis, to provide any Bank with any credit or other information with respect to such operations, business, property, condition or creditworthiness, whether such information comes into its possession on or before the first Event of Default or at any time thereafter. 6.4 FIRST BANK AND AFFILIATES.

Except as may otherwise be expressly stated in this Agreement, the Agent shall be entitled to use its discretion with respect to exercising or refraining from exercising any rights which may be vested in it by, or with respect to taking or refraining from taking any action or actions which it may be able to take under or in respect of, the Loan Documents. The Agent shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Majority Banks, and such instructions shall be binding upon all holders of Notes; provided, however, that the Agent shall not be required to take any action which exposes the Agent to personal liability or which is contrary to the Loan Documents or applicable law. The Agent shall incur no liability under or in respect of any of the Loan Documents by acting upon any notice, consent, certificate, warranty or other paper or instrument believed by it to be genuine or authentic or to be signed by the proper party or parties and to be consistent with the terms of this Agreement. 6.6 NOTICES.

All funds received by the Agent in respect of any payments made by the Borrower on the Notes shall be distributed forthwith by the Agent among the Banks, in like currency and funds as received, ratably according to each Bank's ratable share thereof. After any Event of Default has occurred, all funds received by the Agent, whether as payments by the Borrower or as realization on collateral, shall (except as may otherwise be required by law) be distributed by the Agent in the following order: (a) first to the Agent or any Bank who has incurred unreimbursed costs of collection with respect to any Obligations hereunder, ratably to the Agent and each Bank in the proportion that the costs incurred by the Agent or such Bank bear to the total of all such costs incurred by the Agent and all Banks; (b) next to the Agent for the account of the Banks (in accordance with their respective ratable shares of all Loans outstanding) for application on the Notes and the unpaid drawings under Letters of Credit; (c) next to the Agent for the account of the Banks (in accordance with their respective ratable shares) for any unpaid Revolving Commitment Fees or Letter of Credit Fees owing by the Borrower hereunder; and (d) last to the Agent to be held in the Holding Account to cover the Borrower's reimbursement and other obligations with respect to any outstanding Letters of Credit. 6.9 SHARING OF PAYMENTS. If any Bank shall receive and retain any payment, voluntary or involuntary, whether by setoff, application of deposit balance or security, or otherwise, in respect of Indebtedness under this Agreement or the Notes in excess of such Bank's share thereof as determined under this Agreement, then such Bank shall purchase from the other Banks for cash and at face value and without recourse, such participation in the Notes held by such other Banks as shall be necessary to cause such excess payment to be shared ratably as aforesaid with such other Banks. If any such excess payment or part thereof is thereafter recovered from such purchasing Bank, the related purchases from the other Banks shall be rescinded ratably and the purchase price restored as to the portion of such excess payment so recovered, but without interest. Subject to the participation purchase obligation above, each Bank agrees to exercise any and all rights of setoff, counterclaim or banker's lien first fully against any Notes and participations therein held by such Bank, next to any other Indebtedness of the Borrower to such Bank arising under or pursuant to this Agreement and to any participations held by such Bank in Indebtedness of the Borrower arising under or pursuant to this Agreement, and only then to any other Indebtedness of the Borrower to such Bank. 6.10 RESIGNATION.
