     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.

     To induce the Banks to enter into this Agreement and to make Loans
hereunder, and to induce the Agent to issue Letters of Credit, the Borrower
represents and warrants to the Banks:

     3.1  ORGANIZATION, STANDING, ETC.  The Borrower and each of its corporate
Subsidiaries are corporations duly incorporated and validly existing and in good
standing under the laws of the jurisdiction of their respective incorporation
and have all requisite corporate power and authority to carry on their
respective businesses as now conducted, to (in the instance of the Borrower)
enter into this Agreement and to issue the Notes and to perform its obligations
under the Loan Documents.  The Borrower and each of its Subsidiaries are duly
qualified and in good standing as a foreign corporation in each jurisdiction in
which the character of the properties owned, leased or operated by it or the
business conducted by it makes such qualification necessary.

     3.2  AUTHORIZATION AND VALIDITY.  The execution, delivery and performance
by the Borrower of the Loan Documents have been duly authorized by all necessary
corporate action by the Borrower, and the Loan Documents constitute the legal,
valid and binding obligations of the Borrower, enforceable against the Borrower
in accordance with their respective terms, subject to limitations as to
enforceability which might result from bankruptcy, insolvency, moratorium and
other similar laws affecting creditors' rights generally and subject to
limitations on the availability of equitable remedies.

     3.3  NO CONFLICT; NO DEFAULT.  The execution, delivery and performance by
the Borrower of the Loan Documents will not (a) violate any provision of any
law, statute, rule or regulation or any order, writ, judgment, injunction,
decree, determination or award of any court, governmental agency or arbitrator
presently in effect having applicability to the Borrower, (b) violate or
contravene any provisions of the Articles (or Certificate) of Incorporation or
by-laws of the Borrower, or (c) result in a breach of or constitute a default
under any indenture, loan or credit agreement or any other agreement, lease or
instrument to which the Borrower is a party or by which it or any of its
properties may be bound or result in the creation of any Lien on any asset of
the Borrower or any Subsidiary.  Neither the Borrower nor any Subsidiary is in
default under or in violation of any such law, statute, rule or regulation,
order, writ, judgment, injunction, decree, determination or award or any such
indenture, loan or credit agreement or other agreement, lease or instrument in
any case in which the consequences of such default or violation could constitute
an Adverse Event.  No Default or Event of Default has occurred and is
continuing.

     3.4  GOVERNMENT CONSENT.  No order, consent, approval, license,
authorization or validation of, or filing, recording or registration with, or
exemption by, any governmental or public body or authority is required on the
part of the Borrower or Micron to authorize, or in connection with the Micron
Acquisition or in connection with the execution, delivery and performance of, or
the legality, validity, binding effect or enforceability of the Acquisition
Documents, and the Loan Documents, except those which have already been
obtained.

     3.5  FINANCIAL STATEMENTS AND CONDITION.

          (a)  POST-ACQUISITION BALANCE SHEET.  The Post-Acquisition Balance
Sheet, a copy of which is attached hereto as EXHIBIT H, fairly represents the
Borrower's anticipated consolidated financial condition after giving effect to
the Acquisitions.

          (b)  FINANCIAL PROJECTIONS.  The financial projections for the
Borrower and its Subsidiaries for its fiscal year ending December 31, 1998, and
the forecasted consolidated balance sheet of the Borrower and its Subsidiaries
as at the end of such fiscal year, together with supporting assumptions,
delivered to the Agent in connection with the transactions contemplated by this
Agreement, which are attached hereto as EXHIBIT I, were prepared in good faith
on the basis of information and assumptions that the Borrower believed to be
reasonable as of the date of such projections, and which the Borrower believes
to be reasonable as of the date hereof.  The financial projections for the
Borrower and its Subsidiaries described in Section 4.3(g), when delivered to the
Banks, will have been prepared in good faith on the basis of information and
assumptions that the Borrower believed to be reasonable as of the date such
financial projections were delivered to the Banks.

          (c)  FINANCIAL STATEMENTS.  The Borrower's audited financial
statements as at December 31, 1996 and its unaudited financial statements as at
September 30, 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 the Borrower and its Subsidiaries as at such dates and the results
of its operations and cash flow for the respective periods then ended.  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.  To the best of the Borrower's knowledge,
the audited financial statements of Membrex as at December 31, 1997, when
delivered to the Banks pursuant to Section 4.3, will have been prepared in
accordance with GAAP on a consistent basis and fairly present the financial
condition of Membrex as at such date and the results of its operations and cash
flow for the fiscal year then ended, provided that the foregoing representation
with respect to Membrex shall only be made from and after the Acquisition
Closing Date for the Membrex Acquisition.  As of the dates of such financial
statements, none of the Borrower, any Subsidiary, Micron or Membrex had any
material obligation, contingent liability, liability for taxes or long-term
lease obligation which is not reflected in such financial statements or in the
notes thereto.  Since December 31, 1996, with respect to the Borrower, since
October 31, 1997, with respect to Micron, and December 31, 1997, with respect to
Membrex no Adverse Event has occurred, provided  that the foregoing
representation with respect to Membrex shall only be made from and after the
Acquisition Closing Date for the Membrex Acquisition.

          (d)  SOLVENCY.  On each Acquisition Closing Date, after giving effect
to the applicable Acquisition, the payment of the purchase price and related
costs and expenses, and the Loans to be made and other financing to be obtained
in connection therewith, (a) the present date saleable value of the assets of
the Borrower is in excess of the total amount of its liabilities (including for
purposes of the definition all liabilities, whether or not reflected on a
balance sheet prepared in accordance with GAAP, and whether direct or indirect,
fixed or contingent, secured of unsecured, disputed or undisputed); and (b) the
Borrower will be able to pay its obligations as they mature in the ordinary
course of business as proposed to be conducted following the Acquisitions; and
(c) the Borrower does not have unreasonably small capital to carry out the
business as proposed to be conducted following the Acquisitions.  For purposes
of this Section 4.5 (d), 'present fair saleable value' means the value which
would be realized from an interested purchaser are of all relevant information
relating to the assets or group of assets being sold and who is willing to
purchase under ordinary selling conditions in an existing and not theoretical
market if the assets or group of assets are disposed of within a period of six
(6) months to one year.

     3.6  LITIGATION AND CONTINGENT LIABILITIES.  Except as described in EXHIBIT
C, there are no actions, suits or proceedings pending or, to the knowledge of
the Borrower, threatened against or affecting the Borrower or any Subsidiary or
any of their properties before any court or arbitrator, or any governmental
department, board, agency or other instrumentality which might materially and
adversely affect the Borrower, any subsidiary or any of their respective
properties.  Except as described in EXHIBIT C, neither the Borrower nor any
Subsidiary has any contingent liabilities which are material to the Borrower and
the Subsidiaries as a consolidated enterprise.

     3.7  COMPLIANCE.  The Borrower and its Subsidiaries are in material
compliance with all statutes and governmental rules and regulations applicable
to them.

     3.8  ENVIRONMENTAL, HEALTH AND SAFETY LAWS.  Except as disclosed on EXHIBIT
C hereto, there does not exist any violation by the Borrower or any Subsidiary
of any applicable federal, state or local law, rule or regulation or order of
any government, governmental department, board, agency or other instrumentality
relating to environmental, pollution, health or safety matters which will or
threatens to impose a material liability on the Borrower or a Subsidiary or
which would require a material expenditure by the Borrower or such Subsidiary to
cure.  Except as disclosed on EXHIBIT C hereto, neither the Borrower nor any
Subsidiary has received any notice to the effect that any part of its operations
or properties is not in material compliance with any such law, rule, regulation
or order or notice that it or its property is the subject of any governmental
investigation evaluating whether any remedial action is needed to respond to any
release of any toxic or hazardous waste or substance into the environment, the
consequences of which non-compliance or remedial action could constitute an
Adverse Event.

     3.9  ERISA.  Each Plan, if any, complies with all material applicable
requirements of ERISA and the Code and with all material applicable rulings and
regulations issued under the provisions of ERISA and the Code setting forth
those requirements.  No Reportable Event, other than a Reportable Event for
which the reporting requirements have been waived by regulations of the PBGC,
has occurred and is continuing with respect to any Plan.  All of the minimum
funding standards applicable to such Plans have been satisfied and there exists
no event or condition which would permit the institution of proceedings to
terminate any Plan under Section 4042 of ERISA.  The current value of the Plans'
benefits guaranteed under Title IV or ERISA does not exceed the current value of
the Plans' assets allocable to such benefits.

     3.10 REGULATION U.  The Borrower is not engaged in the business of
extending credit for the purpose of purchasing or carrying margin stock (as
defined in Regulation U of the Board of Governors of the Federal Reserve System)
and no part of the proceeds of any Loan will be used to purchase or carry margin
stock or for any other purpose which would violate any of the margin
requirements of the Board of Governors of the Federal Reserve System.

     3.11 OWNERSHIP OF PROPERTY; LIENS.  The interests of the Borrower and its
Subsidiaries  in their respective  real and personal property are fairly
represented in the financial statements furnished to the Agent pursuant to
Section 3.5 hereof (other than property acquired or disposed of since the date
of such financial statement in the ordinary course of business or in
transactions permitted by this Agreement).  None of the properties, revenues or
assets of the Borrower or any of its Subsidiaries is subject to a Lien, except
for (a) Liens disclosed in the financial statements referred to in SECTION
3.5(c) Liens listed on EXHIBIT D, or (c) Liens allowed under SECTION 4.11.

     3.12 TAXES.  Each of the Borrower and the Subsidiaries has filed all
federal, state and local tax returns required to be filed and has paid or made
provision for the payment of all taxes due and payable pursuant to such returns
and pursuant to any assessments made against it or any of its property and all
other taxes, fees and other charges imposed on it or any of its property by any
governmental authority (other than taxes, fees or charges that are not material
in amount or the amount or validity of which is currently being contested in
good faith by appropriate proceedings and with respect to which reserves in
accordance with GAAP have been provided on the books of the Borrower).  No tax
Liens have been filed and no material claims are being asserted with respect to
any such taxes, fees or charges.  The charges, accruals and reserves on the
books of the Borrower in respect of taxes and other governmental charges are
adequate and the Borrower knows of no proposed material tax assessment against
it or any subsidiary or any basis therefor.

     3.13 SUBSIDIARIES.  EXHIBIT E sets forth as of the date of this Agreement a
list of all Subsidiaries and the number and percentage of the shares of each
class of capital stock owned beneficially or of record by the Borrower or any
Subsidiary therein, and the jurisdiction of incorporation of each Subsidiary.

     3.14 TRADEMARKS, PATENTS.  Except as disclosed on EXHIBIT C hereto, each of
the Borrower and the Subsidiaries possesses or has the right to use all of the
patents, trademarks, trade names, service marks and copyrights, and applications
therefor, and all technology, know-how, processes, methods and designs used in
or necessary for the conduct of its business, without known conflict with the
rights of others.

     3.15 RETIREMENT BENEFITS.  Except as required under Section 4980B of the
Code, Section 601 of ERISA or applicable state law, neither the Borrower nor any
Subsidiary is obligated to provide post-retirement medical or insurance benefits
with respect to employees or former employees.

     3.16 FULL DISCLOSURE.  Subject to the following two sentences, neither the
financial statements referred to in Section 3.5 nor any other certificate,
written statement, exhibit or report furnished by or on behalf of the Borrower,
in connection with or pursuant to the Loan Documents contains any untrue
statement of a material fact or omits to state any material fact necessary in
order to make the statements contained therein not misleading.  Certificates or
statements furnished by or on behalf of the Borrower to the Banks consisting of
projections or forecasts of future results or events have been prepared in good
faith and based on good faith estimates and assumptions of the management of the
Borrower, and the Borrower has no reason to believe that such projections or
forecasts are not reasonable.  With respect to Membrex and Micron, to the best
of the Borrower's knowledge, neither the financial statements referred to in
Section 3.5 nor any other certificate, written statement, exhibit or report
furnished by or on behalf of the Borrower, in connection with or pursuant to the
Loan Documents contains any untrue statement of a material fact or omits to
state any material fact necessary in order to make the statements contained
therein not misleading, provided that the foregoing representation with respect
to Membrex shall only be made from and after the Acquisition Closing Date for
the Membrex Acquisition.

     The following provisions shall govern the relationship of the Agent with
the Banks.

     6.1  APPOINTMENT AND AUTHORIZATION.  Each Bank appoints and authorizes the
Agent to take such action as agent on its behalf and to exercise such respective
powers under the Loan Documents as are delegated to the Agent by the terms
thereof, together with such powers as are reasonably incidental thereto.
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.  The Agent may consult with legal counsel
selected by it and shall not be liable for any action taken or suffered in good
faith by it in accordance with the advice of such counsel.

     6.3  LOAN DOCUMENTS; CREDIT ANALYSIS.  The Agent shall not be under a duty
to examine or pass upon the validity, effectiveness, genuineness or value of any
of the Loan Documents or any other instrument or document furnished pursuant
thereto, and the Agent shall be entitled to assume that the same are valid,
effective and genuine and what they purport to be.  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.  With respect to its Commitments and the
Loans made by it, First Bank shall have the same rights and powers under the
Loan Documents as any other Bank and may exercise the same as though it were not
the Agent consistent with the terms thereof, and First Bank and its Affiliates
may accept deposits from, lend money to and generally engage in any kind of
business with the Borrower as if it were not the Agent.

     6.5  ACTION BY AGENT.  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.  In the event that the Agent shall have acquired actual
knowledge of any Event of Default or Default, the Agent shall promptly give
notice thereof to the Banks.  The Agent shall forward to the Banks copies of all
notices, financial reports and other communications received hereunder from the
Borrower by it as Agent, excluding, however, notices, reports and communications
which by the terms hereof are to be furnished by the Borrower directly to each
Bank.

     6.7  INDEMNIFICATION.  Each Bank agrees to indemnify the Agent, as Agent
(to the extent not reimbursed by the Borrower), ratably according to such Bank's
ratable share of the Loans 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 or incurred by the Agent in any way relating to or arising out of the Loan
Documents or any action taken or omitted by the Agent under the Loan Documents,
provided that no Bank shall be liable for any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements resulting from the Agent's gross negligence or willful
misconduct.  No payment by any Bank under this Section shall relieve the
Borrower of any of its obligations under this Agreement.

     6.8  PAYMENTS AND COLLECTIONS. 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.  If at any time First Bank shall deem it advisable, in
its sole discretion, it may submit to each of the Banks and the Borrower a
written notification of its resignation as Agent under this Agreement, such
resignation to be effective upon the appointment of a successor Agent, but in no
event later than 30 days from the date of such notice.  Upon submission of such
notice, the Majority Banks may appoint a successor Agent.

In such formula, (i) 'Eurocurrency Reserve Percentage' means the average daily
percentage (expressed as a decimal) during the applicable Interest Period

in Regulation D, and (ii) 'LIBO Rate' means the offered rate for deposits in
United States Dollars (rounded upwards, if necessary, to the nearest 1/16 of

Page as of 11:00 a.m., London time, on the day that is two Banking Days

determined by the Agent based on rates offered to the Bank for United States
Dollar deposits in the interbank Eurodollar market. 'Reuters Screen LIBO Page'

writing and signed by the Agent in addition to the requisite Banks indicated
above to take such action, affect the rights or duties of the Agent under this
Agreement or any Loan Document, and (B) no amendment may increase any Bank's

this Section shall survive any termination of this Agreement.

     8.3  SUCCESSORS AND ASSIGNS; DISPOSITION OF LOANS; TRANSFEREES.  This
Agreement shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns, except that the Borrower may not
assign its rights or delegate its obligations hereunder or under any other Loan
Document without the prior written consent of all the Banks.  Each Bank may at
any time sell, assign, transfer, grant participations in, or otherwise dispose
of any portion of its Commitments, and/or its Loans (each such interest so
disposed of being herein called a 'Transferred Interest') to banks or other
financial institutions ('Transferees'); PROVIDED, HOWEVER, that a Bank may
dispose of a Transferred Interest only with the consent of the Agent and, except
after the occurrence and during the continuance of an Event of Default, the

payment to the Agent by the parties to such disposition of a processing and
recording fee in the amount of $2,500 for each party and PROVIDED further, that
except after the occurrence and during the continuance of an Event of Default,
First Bank shall not dispose of a Transferred Interest if, after giving effect
thereto, First Bank's share of the outstanding Commitments and Loans would be
less than 51%.  The Borrower agrees that each Transferee shall be entitled to
the benefits of Section 8.2 with respect to its Transferred Interest and that
each Transferee may exercise any and all rights of banker's Lien, setoff and
counterclaim as if such Transferee were a direct lender to the Borrower.  If any
Bank makes any assignment to a Transferee, then upon notice to the Borrower such
Transferee, to the extent of such assignment (unless otherwise provided
therein), shall become a 'Bank' hereunder and shall have all the rights and
obligations of such Bank hereunder and such Bank shall be released from its
duties and obligations under this Agreement to the extent of such assignment.
Notwithstanding the sale by any Bank of any participation hereunder, (a) no
participant shall be deemed to be or have the rights and obligations of a Bank
hereunder except that any participant shall have a right of setoff under this
Agreement as if it were such Bank and the amount of its participation were owing
directly to such participant by the Borrower and (b) such Bank shall not in
connection with selling any such participation condition such Bank's rights in
connection with consenting to amendments or granting waivers concerning any
matter under any Loan Document upon obtaining the consent of such participant
other than on matters relating to (i) any reduction in the amount of any
principal of, or the amount of or rate of interest on, any Note or Advance in
which such participation is sold, (ii) any postponement of the date fixed for
any payment of principal of or interest on any Note or Advance in which such
participation is sold, (iii) the release or subordination of any material
portion of any collateral other than pursuant to the terms of any Security
Document or (iv) the release of any Guaranty.

     8.4  GOVERNING LAW.  This Agreement and the rights and obligations of the
parties hereunder and under the Note and any other documents delivered herewith
shall be construed in accordance with and governed by the substantive laws (but
not the laws of conflict) of the State of Minnesota but giving effect to all
federal laws applicable to national banking associations.  The Borrower hereby
consents to the jurisdiction of the courts of the State of Minnesota and federal
courts located in the State of Minnesota for any actions brought hereon or on
the Notes.

     8.5  SEVERABILITY.  Whenever possible, each provision of this Agreement and
the other Loan Documents and any other statement, instrument  or transaction
contemplated hereby or thereby or relating hereto or thereto shall be
interpreted in such manner as to be effective and valid under such applicable
law, but, if any provision of this Agreement, the other Loan Documents or any
other statement, instrument or transaction contemplated hereby or thereby or
relating hereto or thereto shall be held to be prohibited or invalid under such
applicable law, such provision shall be ineffective only to the extent of such
prohibition or invalidity, without invalidating the remainder of such provision
or the remaining provisions of this Agreement, the other Loan Documents or any
other statement, instrument or transaction contemplated hereby or thereby or
relating hereto or thereto.

     8.6  WAIVER OF JURY TRIAL.  EACH OF THE BORROWER, THE AGENT AND THE BANKS
IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING
ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR THE
TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

     8.7  INDEMNIFICATION.  The Borrower hereby agrees to defend, protect,
indemnify and hold harmless the Agent and the Banks and their respective
Affiliates and the directors, officers, employees, attorneys and agents of the

an 'Indemnitee' and all of the foregoing being collectively the 'Indemnitees')
from and against any and all claims, actions, damages, liabilities, judgments,
costs and expenses (including all reasonable fees and disbursements of counsel
which may be incurred in the investigation or defense of any matter) imposed
upon, incurred by or asserted against any Indemnitee, whether direct, indirect
or consequential and whether based on any federal, state, local or foreign laws
or regulations (including securities laws, environmental laws, commercial laws
and regulations), under common law or on equitable cause, or on contract or
otherwise:

          (a)  by reason of the Membrex Acquisition or the Micron Acquisition;
or

          (b)  by reason of, relating to or in connection with any act done or
omitted by any Person in connection with, or in the exercise of any rights or
remedies under, the Acquisition Documents; provided, however, that the Borrower
shall not be liable to any Indemnitee for any portion of such claims, damages,
liabilities and expenses resulting from such Indemnitee's gross negligence or
willful misconduct.  In the event this indemnity is unenforceable as a matter of
law as to a particular matter or consequence referred to herein, it shall be
enforceable to the full extent permitted by law.

     This indemnification applies, without limitation, to any act, omission,
event or circumstance existing or occurring on or prior to the later of the
Termination Date or the date of payment in full of the Obligations, including
specifically Obligations arising under clause (b) of this Section.  The
indemnification provisions set forth above shall be in addition to any liability
the Borrower may otherwise have.  Without prejudice to the survival of any other
obligation of the Borrower hereunder the indemnities and obligations of the
Borrower contained in this Section shall survive the payment in full of the
other Obligations.

     8.8  COUNTERPARTS.  This Agreement may be executed in any number of
counterparts, all of which taken together shall constitute one and the same
instrument, and any of the parties hereto may execute this Agreement by signing

     8.10 NO WAIVERS.  No failure or delay on the part of any Bank or the Agent
in exercising any right, power or privilege hereunder and no course of dealing

order regarding capital adequacy, or any change therein or in the interpretation
or application thereof, or compliance by any Bank with any request or directive
regarding capital adequacy (whether or not having the force of law) from any
central bank, governmental agency or body having jurisdiction, does or shall
have the effect of reducing the rate of return on such Bank's or its parent's
capital as a consequence of its obligations hereunder to a level below that
which the Bank or its parent could have achieved but for such adoption, change
or compliance (taking into consideration the Bank's and its parent's policies
with respect to capital adequacy), then the Borrower shall from time to time,
within 10 days after written notice from and demand from such Bank, pay to such
Bank additional amounts sufficient to compensate such Bank for such reduction.
