this Agreement, the Bank agrees to make Loans to and issue Letters of Credit
for the account of the Borrower as follows:

	2.1.1	Loan Commitment.  The Bank will make loans ("Loans") on a
revolving basis from time to time before the Termination Date provided that
the sum of (i) the aggregate outstanding principal amount of all Loans plus
(ii) the aggregate stated amount of all Letters of Credit shall not at any
time exceed $4,000,000.00 (the "Commitment Amount").

	2.1.2	L/C Commitment.  The Bank will issue Letters of Credit in
each case containing such terms and conditions as are permitted by this
Agreement and as are reasonably satisfactory to the Bank, at the request of and
for the account of the Borrower from time to time provided that any Letter of
Credit to be issued shall terminate on or before the Termination Date.

	2.2	Loan Procedures.

	2.2.1	Various Types of Loans.  Each Loan shall be either a Prime
Rate Loan or a LIBOR Loan, as the Borrower shall specify in the related notice
of borrowing or conversion pursuant to Section 2.2.2 or 2.2.3, the form of which
is annexed hereto as Exhibit C.  Prime Rate Loans and LIBOR Loans may be
outstanding at the same time, provided that the aggregate principal amount of
each LIBOR Loan shall at all times be at least $250,000 and an integral multiple
of $100,000.

	2.2.2	Borrowing Procedures.  The Borrower shall give written
notice or telephonic notice (followed immediately by written confirmation
thereof) to the Bank of each proposed Loan not later than (a) in the case of a
Prime Rate Loan, 10:00 A.M., Albany time, on the proposed date of such Loan,
and (b) in the case of a LIBOR Loan, 10:00 A.M., Albany time, two (2) Business
Days prior to the proposed date of such Loan.  Each such notice shall be
effective upon receipt by the Bank, shall be irrevocable, and shall specify the
date, amount and type of Loan.  So long as the conditions precedent set forth in
Section 10 with respect to such Loan have been satisfied and there has been no
default in the payment of any principal, interest or fees to be paid under any
of the Loan Documents, the Bank shall pay over the requested amount to the
Borrower on the requested Loan date.  Each Loan shall be funded on a Business
Day.



	2.2.3	Procedures for Conversion of Type of Loan.  Subject to the
provisions of Section 2.2.1, the Borrower may convert all or any part of any
outstanding Loan into a Loan of a different type by giving written notice or
telephonic notice (followed immediately by written confirmation thereof) to the
Bank not later than (a) in the case of conversion into a Prime Rate Loan,
10:00 A.M., Albany time, on the proposed date of such conversion, and (b) in the
case of a conversion into a LIBOR Loan, 10:00 A.M., Albany time, at least two
(2) Business Days prior to the proposed date of such conversion.  Each properly
given notice shall be effective on the proposed date of such conversion, shall
be irrevocable, and shall specify the date and amount of such conversion, the
Loan to be so converted and the type of Loan into which the Loan
should be converted.  Subject to Section 2.4, such Loan shall be so converted
on the requested date of conversion.  Each conversion shall be on a Business
Day.

	2.3	Letter of Credit Procedures.

	2.3.1	L/C Applications.  The Borrower shall give notice to the
Bank of the proposed issuance of each Letter of Credit on a Business Day which
is at least three Business Days (or such lesser number of days as the Bank
shall agree in any particular instance) prior to the proposed date of issuance
of such Letter of Credit.  Each such notice shall be accompanied by an L/C
Application, duly executed by the Borrower and in all respects satisfactory to
the Bank, together with such other documentation as the Bank may request in
support thereof, it being understood that each L/C Application shall specify,
among other things, the date on which the proposed Letter of Credit is to be
issued, the expiration date of such Letter of Credit (which shall not be later
than the Termination Date) and whether such Letter of Credit is to be
transferable in whole or in part.  So long as the Bank has not received written
notice that the conditions precedent set forth in Section 10 with respect to the
issuance of such Letter of Credit have not been satisfied, the Bank shall issue
such Letter of Credit on the requested issuance date. 

	2.3.2	Reimbursement Obligations.  The Borrower hereby
unconditionally and irrevocably agrees to reimburse the Bank for each payment or
disbursement made by the Bank under any Letter of Credit honoring any demand
for payment made by the beneficiary thereunder, in each case on the date that
such payment or disbursement is made.  Any amount not reimbursed on the date of
such payment or disbursement shall bear interest from the date of such payment
or disbursement to the date that the Bank is reimbursed by the Borrower
therefor, payable on demand, at a rate per annum equal to the Prime Rate from
time to time in effect from time to time in effect plus, beginning on the third
Business Day after receipt of notice from the Bank of such payment or
disbursement, two (2%) percent.  The Bank shall notify the Borrower whenever any
demand for payment is made under any Letter of Credit by the beneficiary
thereunder; provided, however, that the failure of the Bank to so notify the
Borrower shall not affect the rights of the Bank in any manner whatsoever.

	2.3.3	Limitation on Obligations of the Bank.  In determining
whether to pay under any Letter of Credit, the Bank shall have no obligation to
the Borrower other than to confirm that any documents required to be delivered
under such Letter of Credit appear to have been delivered and
appear to comply on their face with the requirements of such Letter of Credit.
Any action taken or omitted to be taken by the Bank under or in connection with
any Letter of Credit, if taken or omitted in the absence of gross negligence and
willful misconduct, shall not impose upon the Bank any liability to the Borrower
and shall not reduce or impair the Borrower's reimbursement obligations set
forth in Section 2.3.2.


	2.4	Certain Conditions.  Notwithstanding any other provision of this
        Agreement, the Bank shall have no obligation to make any Loan, or to
        permit the continuation of or any conversion into any other Type of Loan
        or to issue any Letter of Credit if an Event of Default or Unmatured
        Event of Default (relating to those Events of Default set forth at
        Sections 11.1.1, 11.1.4, 11.1.5, 11.1.6, 11.1.9 or 11.1.10 exists).
        

	SECTION 3	NOTE EVIDENCING LOANS.

	3.1	Note.  The Loans shall be evidenced by a promissory note (the
"Note") substantially in the form set forth in Exhibit C, with appropriate
insertions, payable to the order of the Bank in an amount equal to the
Commitment Amount.

        3.2     Recordkeeping.  The Bank shall record in its records the date
and amount of each Loan made by the Bank and each repayment or conversion
thereof.  The aggregate unpaid principal amount so recorded shall be
rebuttable presumptive evidence of the principal amount owing and unpaid on
such Note.  The failure to so record any such amount or any error in so
recording any such amount shall not, however, limit or otherwise affect the
obligations of the Borrower hereunder or under the Note to repay the principal
amount of the Loans evidenced by such Note together with all interest accruing
thereon.


	SECTION 4	INTEREST.

	4.1	Interest Rates.  The Borrower promises to pay interest on
the unpaid principal amount of each Loan for the period commencing on the date
of such Loan until such Loan is paid in full as follows:

                    (a)   at all times while such Loan is a Prime Rate
          Loan, at a rate per annum equal to the sum of the Prime Rate
          from time to time in effect; and

                    (b)   at all times while such Loan is a LIBOR Loan,
          at a rate per annum equal to the sum of the applicable LIBOR plus
          the LIBOR Rate Margin from time to time in effect;

provided, however, that at any time an Event of Default exists, the interest
rate applicable to each Loan (be it a Prime Rate Loan or LIBOR Loan) may, at
the option of the Bank, be increased up to a rate equal to the Prime Rate plus
2% (200 basis points) per annum.

	4.2	Interest Payment Dates.  Accrued interest on each Loan
shall be payable in arrears on the first Business Day of each calendar month
and at maturity.  After maturity, accrued interest on all Loans shall be
payable on demand.

	4.3	Setting and Notice of LIBOR Rate.  The applicable LIBOR
Rate for each LIBOR Rate Loan shall be determined by the Bank, as of the date
said LIBOR Loan is advanced based upon LIBOR in effect on said date and as set,
shall remain in effect for one month and shall be adjusted to reflect any change
in LIBOR in effect on each successive anniversary of the date that the LIBOR
Loan was advanced, provided that if the anniversary date of said advance does
not exist in any subsequent month, the LIBOR Rate will be adjusted on the last
day of any said month and provided further that if the anniversary date is not
a date on which The Wall Street Journal is published, the change in the LIBOR

Rate shall be based upon LIBOR on the first date immediately prior to the
anniversary date that it is published.  Each determination of the applicable
LIBOR Rate shall be conclusive and binding upon the parties hereto, in the
absence of demonstrable error.  The Bank shall, upon written request of the
Borrower, deliver to the Borrower a statement showing the computations used by
the Bank in determining any applicable LIBOR Rate hereunder.

	4.4	Computation of Interest Rate for Prime Rate Loans.  All
determinations of interest for Prime Rate Loans shall be computed for the actual
number of days elapsed on the basis of a year of 360 days.  The applicable
interest rate for each Prime Rate Loan shall change simultaneously with each
change in the Prime Rate.


	SECTION 5	FEES.

	5.1	Letter of Credit Fees.  The Borrower agrees to pay to the
Bank a letter of credit fee (each a "Letter of Credit Fee") for each Letter of
Credit in an amount equal to the rate per annum in effect from time to time
pursuant to the Bank's then-current letter of credit fee schedule.  Such Letter
of Credit Fee shall be payable in advance on the first Business Day of each
calendar quarter and on the date of issuance of each Letter of Credit.

	SECTION 6	REDUCTION AND TERMINATION OF THE COMMITMENT; 
                    PREPAYMENTS.

	6.1	Reduction or Termination of the Commitment.  The Borrower
may from time to time on at least five Business Days' prior written notice
received by the Bank permanently reduce the Commitment Amount to an amount not
less than the sum of the aggregate unpaid principal amount of the Loans.  The
Borrower may at any time on like notice terminate the Commitment upon payment in
full of all Loans and all other obligations of the Borrower hereunder or under
any other Loan Documents.

	6.2	Voluntary Prepayments.  The Borrower may from time to time
prepay the Loans in whole or in part, provided that (a) the Borrower shall give
the Bank notice thereof not later than 10:00 A.M., Albany time, on the day of
such prepayment (which shall be a Business Day) specifying the Loans to be
prepaid and the date and amount of prepayment and (b) each partial prepayment
shall, in the case of a LIBOR Loan, be in a principal amount of at least
$250,000 and an integral multiple thereof.


	SECTION 7	MAKING AND PRORATION OF PAYMENTS; SETOFF; TAXES.

	7.1	Making of Payments.  All payments of principal of or
interest on the Note shall be made by the Borrower to the Bank in immediately
available funds at the office specified by the Bank not later than noon, Albany
time, on the date due; and funds received after that hour shall be deemed to
have been received by the Bank on the next following Business Day.

	7.2	Application of Certain Payments.  Each payment of principal
shall be applied to such Loans as the Borrower shall direct by notice to be
received by the Bank on or before the date of such payment or, in the absence of
such notice, as the Bank shall determine in its reasonable discretion.  

	7.3	Due Date Extension.  If any payment of principal or interest
with respect to any of the Notes, falls due on a day which is not a Business
Day, then such due date shall be extended to the immediately following Business

Day and, in the case of principal, additional interest shall accrue and be
payable for the period of any such extension.

	7.4	Setoff.  The Borrower agrees that the Bank has all rights of
set-off and bankers' lien provided by applicable law, and in addition thereto,
the Borrower agrees that at any time any Event of Default exists, the Bank may
apply to the payment of any obligations of the Borrower hereunder, whether or
not then due, any and all balances, credits, deposits, accounts or moneys of the
Borrower then or thereafter with the Bank.

	7.5	Taxes.  All payments of principal of, and interest on, the
Loans and all other amounts payable hereunder shall be made free and clear of
and without deduction for any present or future income, excise, stamp or
franchise taxes and other taxes, fees, duties, withholdings or other charges of
any nature whatsoever imposed by any taxing authority, but excluding franchise
taxes and taxes imposed on or measured by the Bank's net income or receipts (all
non-excluded items being called "Taxes").  If any withholding or deduction from
any payment to be made by the Borrower hereunder is required in respect of any
Taxes pursuant to any applicable law, rule or regulation, then the Borrower
will:

                    (a)   pay directly to the relevant authority the full
          amount required to be so withheld or deducted;

                    (b)   promptly forward to the Bank an official receipt
          or other documentation satisfactory to the Bank evidencing such
          payment to such authority; and

                    (c)   pay to the Bank such additional amount or amounts
          as is necessary to ensure that the net amount actually received by
          the Bank will equal the full amount the Bank would have received
          had no such withholding or deduction been required.

Moreover, if any Taxes are directly asserted against the Bank with respect to
any payment received by the Bank hereunder, the Bank may pay such Taxes and the
Borrower will promptly pay such additional amounts (including any penalty,
interest and expense) as is necessary in order that the net amount received by
such Person after the payment of such Taxes (including any Taxes on such
additional amount) shall equal the amount such Person would have received had
such Taxes not been asserted.

	If the Borrower fails to pay any Taxes when due to the appropriate
taxing authority or fails to remit to the Bank, the required receipts or other
required documentary evidence, the Borrower shall indemnify the Bank for any
incremental Taxes, interest or penalties that may become payable by the Bank as
a result of any such failure.

on the National Priorities List, 40 C.F.R. Part 300 Appendix B; (b) that any
hazardous waste, as defined by 42 U.S.C.  6903(5), any hazardous substance as
defined by 42 U.S.C.  9601(14), any pollutant or contaminant as defined by 42
U.S.C.  9601(33) or any toxic substance, oil or hazardous material or other
chemical or substance regulated by any Environmental Law, excluding household
hazardous waste (all of the foregoing, "Hazardous Substances"), which any one of
them has generated, transported or disposed of has been found at any site at
which a Federal, state or local agency or other third party has conducted a
remedial investigation, removal or other response action pursuant to any
Environmental Law; (c) that the Borrower or any Subsidiary must conduct a
remedial investigation, removal, response action or other activity pursuant to
any Environmental Law; or (d) of any Environmental Claim.

                    (c)   Handling of Hazardous Substances.  Except as set forth
on Schedule 8.15, (i) no portion of any real property or other assets owned,
leased or operated by the Borrower or any Subsidiary has been used for the
handling, processing, storage or disposal of Hazardous Substances except in
accordance in all material respects with applicable Environmental Laws; and no
underground tank or other underground storage receptacle for Hazardous
Substances is located on such properties; (ii) in the course of any activities
conducted by the Borrower, any Subsidiary or the operators of any real property
owned, leased or operated by either the Borrower or any Subsidiary, no Hazardous
Substances have been generated or are being used on such properties except in
accordance in all material respects with applicable Environmental Laws; (iii)
there have been no Releases or threatened Releases of Hazardous Substances on,
upon, into or from any real property or other assets owned, leased or operated
by the Borrower or any Subsidiary, which Releases singly or in the aggregate
might reasonably be expected to have a material adverse effect on the value of
such real property or assets; (iv) to the Borrower's actual knowledge, there
have been no Releases on, upon, from or into any real property in the vicinity
of any real property or other assets owned, leased or operated by either the
Borrower or any Subsidiary which, through soil or groundwater contamination,
may have come to be located on, and which might reasonably be expected to have a
material adverse effect on the value of, any real property or other assets
owned, leased or operated by either the Borrower or any Subsidiary; and (v)

any Hazardous Substances generated by either the Borrower or its Subsidiaries
have been transported offsite only by properly licensed carriers and delivered
only to treatment or disposal facilities maintaining valid permits as required
under applicable Environmental Laws, which transporters and facilities have been
and are, to the best of the Borrower's knowledge, operating in compliance with
such permits and applicable Environmental Laws.

                    (d)   Investigations.  Except as set forth on Schedule 8.15,
the Borrower and their Subsidiaries have taken all reasonable steps to
investigate the past and present condition and usage of any real property owned,
leased or operated by either the Borrower or its Subsidiaries and the operations
conducted by either the Borrower or its Subsidiaries with regard to
environmental matters.

	8.16	Year 2000 Problem.  The Borrower and its Subsidiaries have
reviewed the areas within their business and operations which could be
adversely affected by, and have developed or are developing a program to
address on a timely basis, the "Year 2000 Problem" (that is, the risk that
computer applications used by the Borrower and its Subsidiaries may be unable
to recognize and perform properly date-sensitive functions involving certain
dates prior to and any date after December 31, 1999).  Based on such review
and program, the Borrower reasonably believes that the "Year 2000 Problem" will
not have a Material Adverse Effect.

	8.17	Copyrights, Patents, Trademarks and Licenses, etc.  The
Borrower and its Subsidiaries own or are licensed or otherwise have the right to
use all of the patents, trademarks, service marks, trade names, copyrights,
contractual franchises, authorizations and other rights that are reasonably
necessary for the operation of their respective businesses, all as set forth on
Schedule 8.17, without conflict with the rights of any other Person.  No slogan
or other advertising device, product, process, method, substance, part or other
material now employed, or now contemplated to be employed, by the Borrower or
any Subsidiary infringes upon any rights held by any other Person.  No claim or
litigation regarding any of the foregoing is pending or, to the knowledge of the
Borrower, threatened, and no patent, invention, device, application, principle
or any statute, law, rule, regulation, standard or code is pending or, to the
knowledge of the Borrower, proposed, which, in either case, could reasonably be
expected to have a Material Adverse Effect.

	8.18	Transactions with Affiliates.  Neither the Borrower nor any
Subsidiary have entered into or participated in any agreements or transactions
of any kind with any Affiliates of the Borrower except agreements or
transactions entered into in the ordinary course of business or as disclosed to
the Bank.

	8.19	Information.  All information heretofore or
contemporaneously herewith furnished in writing by the Borrower or any
Subsidiary to the Bank for purposes of or in connection with this Agreement and
the transactions contemplated hereby is, and all written information hereafter
furnished by or on behalf of the Borrower or any Subsidiary to the Bank pursuant
hereto or in connection herewith will be, true and accurate in every material
respect on the date as of which such information is dated or certified, and none
of such information is or will be incomplete by omitting to state any material
fact necessary to make such information not misleading in light of the
circumstances under which made (it being recognized by the Bank that (a) any
projection s and forecasts provided by the Borrower are based on good faith
estimates and assumptions believed by the Borrower to be reasonable as of the
date of the applicable projections or assumptions and that actual results during
the period or periods covered by any such projections and forecasts may differ

from projected or forecasted results and (b) any information provided by the
Borrower or any Subsidiary with respect to any Person or assets acquired or to
be acquired by the Borrower or any Subsidiary shall, for all periods prior to
the date of such acquisition, be limited to the knowledge of the Borrower or
the acquiring Subsidiary after reasonable inquiry).

          Borrower or any Subsidiary or to which any of the properties

          the Controlled Group or any other Person to terminate any Pension
          Plan, or the failure of any member of the Controlled Group to make
          a required contribution to any Pension Plan (if such failure is
          sufficient to give rise to a lien under Section 302(f) of ERISA)
          or to any Multiemployer Pension Plan, or the taking of any action
          with respect to a Pension Plan which could result in the requirement
          that the Borrower furnish a bond or other security to the PBGC or
          such Pension Plan, or the occurrence of any event with respect to
          any Pension Plan or Multiemployer Pension Plan which could result
          in the incurrence by any member of the Controlled Group of any
          material liability, fine or penalty (including any claim or
          demand forwithdrawal liability or partial withdrawal from any
          Multiemployer Pension Plan), or any material increase in the
          contingent liability of the Borrower with respect to any
          post-retirement Welfare Plan benefit, or any notice that any
          Multiemployer Pension Plan is in reorganization, that increased
          contributions may be required to avoid a reduction in plan benefits
          or the imposition of an excise tax, that any such plan is or has
          been funded at a rate less than that required under Section 412
          of the Code, that any such plan is or may be terminated, or that
          any such plan is or may become insolvent;

                    (d)   any cancellation or material change in any
          insurance maintained by the Borrower or any Subsidiary;

                    (e)   any event (including (i) any violation of any
          Environmental Law or the assertion of any Environmental Claim
          or (ii) the enactment or effectiveness of any law, rule or

          Adverse Effect; or

                    (f)   any setoff, claims, withholdings or other defenses

information concerning the Borrower and its Subsidiaries as the Bank may
reasonably request.

	9.2	Books, Records and Inspections.  Keep, and cause each
Subsidiary to keep, its books and records in accordance with sound business
practices sufficient to allow the preparation of financial statements in
accordance with GAAP; permit, and cause each Subsidiary to permit, the Bank or
any representative thereof to inspect the properties and operations of the
Borrower and of such Subsidiary; and permit, and cause each Subsidiary to
permit, at any reasonable time and with reasonable notice (or at any time
without notice if an Event of Default exists), the Bank or any representative
thereof to visit any or all of its offices, to discuss its financial matters
with its officers and its independent auditors (and the Borrower hereby
authorizes such independent auditors to discuss such financial matters with the
Bank or any representative thereof) and to examine (and, at the expense of the
Borrower or the applicable Subsidiary, photocopy extracts from) any of its books
or other corporate records.

	9.3	Insurance.  Maintain, and cause each Subsidiary to
maintain, with responsible insurance companies, such insurance as may be

situated and that is acceptable to the Bank; and, on each anniversary of the

Bank a certificate setting forth in reasonable detail the nature and extent of
all insurance maintained by the Borrower and its Subsidiaries.

to pay, prior to delinquency, all taxes and other governmental charges against
it or any of its property, as well as claims of any kind which, if unpaid, might
become a Lien on any of its property; provided, however, that the foregoing
shall not require the Borrower or any Subsidiary to pay any such tax or charge
so long as it shall contest the validity thereof in good faith by appropriate
proceedings and shall set aside on its books adequate reserves with respect
thereto in accordance with GAAP.

	9.5	Maintenance of Existence, etc.  Maintain and preserve, and
(subject to Section 9.10) cause each Subsidiary to maintain and preserve, (a)
its existence and good standing in the jurisdiction of its incorporation and (b)

jurisdiction where the nature of its business makes such qualification necessary

standing does not have a Material Adverse Effect).

          Debt of Plug Power owed to Borrower in the aggregate in excess
          of $750,000 during any Fiscal Year, provided that Debt in excess

                    (b)   Liens arising in the ordinary course of business
          (such as (i) Liens of carriers, warehousemen, mechanics and

          for sums not overdue or being contested in good faith by
          appropriate proceedings and not involving any deposits or
          advances or borrowed money or the deferred purchase price of
          property or services, and, in each case, for which it maintains

          interests on any property securing debt incurred for the purpose
          of financing all or any part of the cost of acquiring such

          solely to the property so acquired;

                    (e)   attachments, appeal bonds, judgments and other
          similar Liens, for sums not exceeding $250,000 arising in
          connection with court proceedings, provided the execution or

          claims secured thereby are being actively contested in good
          faith and by appropriate proceedings;

                    (f)   easements, rights of way, restrictions, minor

Subsidiary to, be a party to any merger or consolidation, or purchase or
otherwise acquire all or substantially all of the assets or any stock of any

sell, transfer, convey or lease all or any substantial part of its assets, or
sell or assign with or without recourse any receivables.

	9.10	Modification of Organizational Documents.  Not permit the
Certificate of Incorporation, By-Laws or other organizational documents of the
Borrower or any Subsidiary to be amended or modified in any way which might
reasonably be expected to materially adversely affect the interests of the Bank.

	9.11	Use of Proceeds.  Use the proceeds of the Loans solely to
finance the Borrower's working capital and to make advances to Plug Power,
provided, however, that advances to Plug Power shall be limited to $1,000,000
(exclusive of the $750,000 permitted at Section 9.7 herein).  As a condition to
any advance of Loan proceeds to Plug Power, Borrower must demonstrate to the
Bank that the total of all Loans and Letters of Credit outstanding are seventy
(70%) percent or less of Borrower's Acceptable Accounts.  If at any time this
requirement is not met, Borrower must either (i) demand and receive payment of
said advances from Plug Power or (ii) reduce the aggregate amount of Loans and
Letter of Credit to a level that will allow the condition to be met.  Borrower
will not use or permit any proceeds of any Loans to be used, either directly or
indirectly, for the purpose, whether immediate, incidental or ultimate, of
"purchasing or carrying" any Margin Stock.

	9.12	Further Assurances.  Take, and cause each Subsidiary to
take, such actions as are necessary, or as the Bank may reasonably request,
from time to time (including the execution and delivery of guaranties, security
agreements, pledge agreements, financing statements and other documents, the
filing or recording of any of the foregoing, and the delivery of stock
certificates and other collateral with respect to which perfection is obtained
by possession) to ensure that the obligations of the Borrower hereunder and

under the other Loan Documents are secured by (i) substantially all of the
assets of the Borrower and guaranteed by all of the Subsidiaries (including,
promptly upon the acquisition or creation thereof, any Subsidiary acquired or
created after the date hereof) by execution of a counterpart of the Guaranty and
(ii) the obligations of the Guarantor under the Guaranty are secured as required
hereunder.

	9.13	Transactions with Affiliates.  Not, and not permit any
Subsidiary to, enter into, or cause, suffer or permit to exist any transaction,
arrangement or contract with any of its other Affiliates(other than the Borrower
and its Subsidiaries) which is on terms which are less favorable than are
obtainable from any Person which is not one of its Affiliates.

	9.14	Employee Benefit Plans.  Maintain, and cause each Subsidiary
to maintain, each Pension Plan in substantial compliance with all applicable
requirements of law and regulations.

	9.15	Environmental Matters.  (a) If any material Release or
Disposal of Hazardous Substances shall occur or shall have occurred on any real
property or any other assets owned, leased or operated by either the Borrower or
any Subsidiary, the Borrower shall, and shall cause the applicable Subsidiary
to, cause the prompt containment and removal of such Hazardous Substances and
the remediation of such real property or other assets as necessary to comply in
all material respects with all Environmental Laws and to preserve the value of
such real property or other assets.  Without limiting the generality of the
foregoing, the Borrower shall, and shall cause each Subsidiary to, comply in a
reasonable and cost-effective manner with any valid Federal or state judicial or
administrative order requiring the performance at any real property owned,
leased or operated by either the Borrower or any Subsidiary of activities in
response to the Release or threatened Release of a Hazardous Substance except
for the period of time that the Borrower or such Subsidiary is diligently and in
good faith contesting such order.

                    (b)   To the extent that the transportation of "hazardous
          waste" as defined by RCRA is permitted by this Agreement, the Borrower
          shall, and shall cause its Subsidiaries to, dispose of such hazardous
          waste only at licensed disposal facilities operating, to the best of
          the Borrower's or such Subsidiary's knowledge after reasonable
          inquiry, in compliance with Environmental Laws.

	9.16	Unconditional Purchase Obligations.  Not, and not permit
any Subsidiary to, enter into or be a party to any contract for the purchase of
materials, supplies or other property or services, if such contract requires
that payment be made by it regardless of whether or not delivery is ever made of
such materials, supplies or other property or services; provided that the fore
going shall not prohibit the Borrower or any Subsidiary from entering into
options for the purchase of particular assets or businesses.

	9.17	Inconsistent Agreements.  Not, and not permit any Subsidiary
to, enter into any agreement containing any provision which (a) would be
violated or breached by any borrowing by the Borrower hereunder or by the
performance by the Borrower or any Subsidiary of any of their obligations
hereunder or under any other Loan Document or (b) would prohibit the Borrower or
any Subsidiary from granting to the Bank, a Lien on any of their assets.

	9.18	Advances and Other Investments.  Not, and not permit any
Subsidiary to, make, incur, assume or suffer to exist any Investment in any
other Person, except (without duplication) the following:


                    (a)   the advances permitted pursuant to Section 9.7
          and Section 9.11 herein;

                    (b)   equity Investments existing on the Effective Date
          in Subsidiaries identified in Schedule 8.8; and

                    (c)   the Guarantor's bank deposits in the ordinary
          course of business; provided that the aggregate amount of all
          such deposits (excluding amounts in payroll accounts or for
          accounts payable, in each case to the extent that checks have
          been issued to third parties) which are maintained with any bank
          other than the Bank shall not at any time exceed the amount(s)
          necessary for payroll plus $50,000;

provided, however, that no Investment otherwise permitted by clause (b) shall be
permitted to be made if, immediately before or after giving effect thereto, any
Event of Default or Unmatured Event of Default shall have occurred and be
continuing.

	9.19	Maintenance of Property.  The Borrower shall, and shall
cause each Subsidiary to, maintain and preserve all its property which is used
or useful in its business in good working order and condition, ordinary wear and
tear excepted.

	9.20	Performance of Obligations.  The Borrower shall, and shall
cause each Subsidiary to, pay and discharge as the same shall become due and
payable, all their respective obligations and liabilities, including:

                    (a)   all tax liabilities, assessments and governmental
          charges or levies upon it or its properties or assets; and

                    (b)   all lawful claims which, if unpaid, would by law
          become a Lien upon its property; unless, in each case, the same
          are being contested in good faith by appropriate proceedings and
          adequate reserves in accordance with GAAP are being maintained
          by the Borrower or such Subsidiary.
