Type of Loans to be Converted into and, if to be Converted into a Eurodollar
Loan, the Interest Period to be initially applicable thereto.

2.7.	Interest. (a) Interest on Prime Rate Loans. During such periods as a
Loan is a Prime Rate Loan, the unpaid principal amount of such Loan shall bear
interest at a fluctuating rate per annum which shall at all times be equal to
the Prime Rate in effect from time to time.

(b)	Interest on Eurodollar Loans. During such periods as a Loan is a
Eurodollar Loan, the unpaid principal amount of such Loan shall bear interest

including the date of a Loan to but excluding the date of any prepayment or
repayment thereof and shall be payable in the case of any Loan, (i) which is a

days.

(f)	Availability of Eurodollar Pricing Option; Determination of Applicable
Eurodollar Margin. A Prime Rate Loan may not be Converted, in whole or in part,
into a Eurodollar Loan, and a Eurodollar Loan may not be Continued, in whole or
in part, for an additional Interest Period or Interest Periods, during any
period (a "Eurodollar Pricing Blackout Period") in which there is no currently
effective Applicable Eurodollar Margin which has been determined by the Lender
in accordance with the provisions hereof. The Lender shall have the right at
any time, based upon a good faith review by it of the factors reflected in the
Pricing Grid Tables, information known by it and upon its good faith conclusion
that the conditions and requirements necessary to establish and determine an
Applicable Eurodollar Margin have not been met or achieved, to withdraw any
currently effective determination by it of the Applicable Eurodollar Margin,
such withdrawal to be effective on not less than one Business Days' prior
written notice to the Borrower. For all purposes of this Agreement, there shall
be considered to be in effect a currently effective Applicable Eurodollar
Margin only if the Lender shall have given the Borrower written notice of its
determination of the Applicable Eurodollar Margin in accordance with the
provisions of this section 2.7(f) and such determination shall not have been
withdrawn by the Lender in accordance with the above preceding sentence.

As used herein, the term "Applicable Eurodollar Margin", as applied to any
Eurodollar Loan, means the particular rate per annum determined by the Lender
from time to time in accordance with the Pricing Grid Tables which appear below
and the following provisions:

(i)	The Lender shall determine the Applicable Eurodollar Margin from time
to time whenever it reasonably believes that the factors identified in the
Pricing Grid Tables have initially been achieved or have changed. Any
determination by the Lender of the Applicable Eurodollar Margin shall become
effective on such date as the Lender may specify on not less than one Business
Days' prior written notice to the Borrower. Any determination by the Lender of
any of the matters referred to in this section 2.7(f) shall be conclusive and
binding upon the parties absent manifest error.

(ii)	Notwithstanding the above provisions, during any period when (1) a
Default under section 8.1(a) has occurred and is continuing, or (2) an Event of
Default has occurred and is continuing, the Applicable Eurodollar Margin shall
be the highest rate per annum indicated therefor in the Pricing Grid Tables,
regardless of any other factors.

(iii)	If the Lender determines at any time that the Applicable Eurodollar
Margin could be determined on the basis indicated for both of the Pricing Grid
Tables, and the Applicable Eurodollar Margin would be smaller if one Pricing
Grid Table were used rather than the other, the Lender's determination of the
Applicable Eurodollar Margin shall be made on the basis of the smaller
Applicable Eurodollar Margin.


(iv)	The Pricing Grid Table which appears below shall be used at such time
or times as the Lender shall have determined that (1) some or all of the
Pledged Shares are covered by a currently effective registration statement
filed under the 1933 Act, (2) the Borrower is not constrained from selling such
Pledged Shares by the terms of any "lock-up" or other restriction contained in
any other document or by any other applicable requirement, and (3) such Pledged
Shares are listed and could be freely traded on NASDAQ or a national stock
<PAGE>
exchange (the number of Pledged Shares which meet all of the foregoing
requirements are herein sometimes referred to as the "Registered Pledged
Shares").

(vi)	The Lender has assumed, solely for purposes of preparing the Pricing
Grid Tables, that 6,000,000 shares of the Company's Common Stock will be
offered in the IPO (subject to an overallotment option for the underwriters of
900,000 shares) at an offering price of between $13.00 and $15.00 per share,
and that after giving effect to the IPO (but not the overallotment option) the
Company will have approximately 42,208,480 shares of its Common Stock
outstanding and the Borrower will own approximately 13,700,000, or
approximately 32.5% of such outstanding shares. If any of such assumptions are
incorrect, the Lender shall modify the trading volume and Average Per Share
Prices reflected in the Pricing Grid Tables appropriately and shall notify the
Borrower of such modifications in writing, whereupon this Agreement shall be
deemed amended to reflect the modifications as so notified by the Lender.

(vii)	If at any time subsequent to the Closing Date any of the following
events occurs, the Lender shall modify the trading volume and Average Per Share
Prices reflected in the Pricing Grid Tables appropriately and shall notify the
Borrower of such modifications in writing, whereupon this Agreement shall be
deemed amended to reflect the modifications as so notified by the Lender:

(1)	the Company shall issue or sell any shares of its Common Stock in a
public offering or placement with institutional investors;

(2)	the Company shall grant, issue or sell (whether directly or by
assumption in a merger or otherwise) any rights or warrants to subscribe for or
to purchase, or any options for the purchase of, its Common Stock or any stock
or securities convertible into or exchangeable for its Common Stock, other than
pursuant to the stock option and employee stock ownership plans as described in
the Registration Statement;

(3)	the Company shall issue or sell (whether directly or by assumption in a
merger or otherwise) any stock or securities convertible into or exchangeable
for its Common Stock;

(4)	the Company shall declare an extraordinary dividend or distribution
upon any stock of the Company;

(5)	there shall be a stock dividend, stock split, reverse stock split,
stock reclassification, reduction of capital, or other similar event with
respect to the capital stock of the Company;

(6)	the Company or any of its Subsidiaries shall directly or indirectly
purchase, repurchase, redeem or otherwise acquire for value or retire any
shares of the capital stock of the Company; or

(7)	shares of the capital stock of the Company shall be issued, or shall be
converted or exchanged into other securities or property, in connection with a
merger or consolidation involving the Company or any of its Subsidiaries.

(g)	Information as to Interest Rates. The Lender upon determining the
interest rate for any Loan shall promptly notify the Borrower thereof.


<PAGE>
2.8.	Selection and Continuation of Interest Periods. (a) The Borrower shall
have the right

(x)	at the time it gives a Notice of Conversion in respect of the
Conversion into a Eurodollar Loan, to select in such Notice the Interest Period
to be applicable to such Eurodollar Loan, and

(y)	prior to 11:00 A.M. (local time at the Notice Office) on the third
Business Day prior to the expiration of an Interest Period applicable to a
Eurodollar Loan, to elect by giving the Lender written or telephonic notice (in
the case of telephonic notice, promptly confirmed in writing if so requested by
the Lender) to Continue all or the Minimum Borrowing Amount of the principal
amount of such Eurodollar Loan as one or more Eurodollar Loans and to select
the Interest Period to be applicable to any such Eurodollar Loan (any such
notice, a "Notice of Continuation"),

which Interest Period shall, at the option of the Borrower, be a one, two,
three or six month period; provided, that notwithstanding anything to the
contrary contained above, the Borrower's right to select an Interest Period or
to effect any Continuation shall be subject to the applicable provisions of
section 2.9 and to the following:

(i)	no Eurodollar Loan may result from a Conversion, and no Interest Period
for a Eurodollar Loan may be Continued, during any Eurodollar Pricing Blackout
Period;

(ii)	the initial Interest Period for any Eurodollar Loan shall commence on
the date of the Conversion into or initial Continuation of such Eurodollar Loan
and each Interest Period occurring thereafter in respect of such Eurodollar
Loan shall commence on the day on which the next preceding Interest Period
expires;

(iii)	if any Interest Period begins on a day for which there is no
numerically) corresponding day in the calendar month at the end of such
Interest Period, such Interest Period shall end on the last Business Day of
such calendar month;

(iv)	if any Interest Period would otherwise expire on a day which is not a
Business Day, such Interest Period shall expire on the next succeeding Business
Day, provided that if any Interest Period would otherwise expire on a day which
is not a Business Day but is a day of the month after which no further Business
Day occurs in such month, such Interest Period shall expire on the next
preceding Business Day;

(v)	no Interest Period for any Eurodollar Loan may be selected which would
end after the Maturity Date;

(vi)	no Eurodollar Loan resulting from a Continuation shall be in a
principal amount less than the Minimum Borrowing Amount applicable thereto; and

(vii)	no Interest Period may be elected at any time when a Default under
section 8.1(a) or an Event of Default is then in existence unless the Lender
otherwise agrees.

(b)	If upon the expiration of any Interest Period the Borrower would have
been entitled to but has failed to Continue the respective Eurodollar Loan by
electing a new Interest Period to be applicable thereto as provided above, the
Borrower shall be deemed to have elected to Continue such Eurodollar Loan for
an additional Interest Period of the shorter of (i) the same length as the
<PAGE>
expiring Interest Period or (ii) the longest Interest Period otherwise
permissible under section 2.8(a)(iv). In such circumstance, the Lender shall
determine the relevant Adjusted Eurodollar Rate applicable to such additional
Interest Period two Business Days prior to the commencement of such additional
Interest Period. If upon the expiration of any Interest Period the Borrower is
not entitled to elect a new Interest Period to be applicable to a Eurodollar
Loan as provided above, the Borrower shall be deemed to have elected to Convert
such Eurodollar Loan to a Prime Rate Loan effective as of the expiration date
of such current Interest Period.

2.9.	Illegality, Increased Costs, etc. (a) If the Lender shall notify the
Borrower that the introduction of or any change in or in the interpretation of
any law or regulation makes it unlawful, or any central bank or other
governmental authority asserts that it is unlawful, for the Lender or its
Applicable Lending Office to perform its obligations hereunder to make
Eurodollar Loans or to fund or maintain Eurodollar Loans hereunder, (i) the
obligation of the Lender to Continue a Eurodollar Loan for a new Interest
Period commencing on the expiration of the current Interest Period, or to
Convert a Prime Rate Loan into a Eurodollar Loan, as applicable, shall be
suspended until the Lender shall notify the Borrower that the circumstances
causing such suspension no longer exist and (ii) the Borrower shall forthwith
prepay in full all Eurodollar Loans then outstanding, together with interest
accrued thereon, unless the Borrower, within five Business Days of notice from
the Lender, Converts all Eurodollar Loans then outstanding into Prime Rate
Loans.


(b)	If the Lender shall have determined that after the Effective Date, the
adoption of any applicable law, rule or regulation regarding capital adequacy,
or any change therein, or any change in the interpretation or administration
thereof by any governmental authority, central bank or comparable agency
charged by law with the interpretation or administration thereof, or compliance
by the Lender or its parent corporation with any request or directive regarding
capital adequacy (whether or not having the force of law) of any such
authority, central bank, or comparable agency, in each case made subsequent to
the Effective Date, has or would have the effect of reducing by an amount
reasonably deemed by the Lender to be material the rate of return on the
Lender's or its parent corporation's capital or assets as a consequence of the
Lender's commitments or obligations hereunder to a level below that which the
Lender or its parent corporation could have achieved but for such adoption,
effectiveness, change or compliance (taking into consideration the Lender's or
its parent corporation's policies with respect to capital adequacy), then from
time to time, within 15 days after demand by the Lender, the Borrower shall pay
to the Lender such additional amount or amounts as will compensate the Lender
or its parent corporation for such reduction. The Lender, upon determining in
good faith that any additional amounts will be payable pursuant to this section
2.9(b), will give prompt written notice thereof to the Borrower, which notice
shall set forth, in reasonable detail, the basis of the calculation of such
additional amounts, which basis must be reasonable, although the failure to
give any such notice shall not release or diminish the Borrower's obligations
to pay additional amounts pursuant to this section 2.9(b) upon the subsequent
receipt of such notice.

(c)	Notwithstanding anything in this Agreement to the contrary, (i) the
Lender shall not be entitled to compensation or payment or reimbursement of
other amounts under section 2.9(b) for any amounts incurred or accruing more
than 180 days prior to the giving of notice to the Borrower of additional costs
or other amounts of the nature described in such section, and (ii) the Lender
shall not demand compensation for any reduction referred to in section 2.9(b)
<PAGE>
if it shall not at the time be the general policy or practice of the Lender to
demand such compensation, payment or reimbursement in similar circumstances
under comparable provisions of other credit agreements.

2.10.	Breakage Compensation. The Borrower shall compensate the Lender, upon
its written request (which request shall set forth the detailed basis for
requesting and the method of calculating such compensation), for all reasonable
losses (including loss of anticipated profits), expenses and liabilities
(including, without limitation, any loss, expense or liability incurred by
reason of the liquidation or reemployment of deposits or other funds required
by the Lender to fund its Eurodollar Loans) which the Lender may sustain: (i)
if for any reason (other than a default by the Lender), a Continuation of, or
Conversion into, a Eurodollar Loan by the Borrower does not occur on a date
specified therefor in a Notice of Continuation or Notice of Conversion, (ii) if
any repayment, prepayment, Continuation or Conversion of any of its Eurodollar
Loans occurs on a date which is not the last day of an Interest Period
applicable thereto; (iii) if any prepayment of any of its Eurodollar Loans is
not made on any date specified in a notice of prepayment given by the Borrower;
or (iv) as a consequence of any other default by the Borrower to repay its
Eurodollar Loans when required by the terms of this Agreement.

(c)	no partial prepayment of any Loan shall reduce the principal amount of
such Loan to an amount less than the Minimum Borrowing Amount applicable
thereto;

(d)	each prepayment pursuant to this section 3.1 shall be applied to the
Scheduled Repayments in order of maturity; and

to, and shall, repay $3,750,000 aggregate principal amount of the Loans, and on
the Maturity Date the Borrower shall repay the entire remaining aggregate
principal amount of the outstanding Loans (each such repayment, a "Scheduled
Repayment"). Voluntary prepayments of the Loans pursuant to section 3.1 and
mandatory prepayments of the Loans pursuant to section 3.2(c) will be applied
to the Scheduled Repayments in order of maturity.

(b)	If Collateral Coverage Ratio Not Met. If on any date (after giving
effect to any other payments on such date) the Lender determines (which
determination shall be binding on the parties, in the absence of manifest
error) that the Collateral Coverage Ratio is less than 4.00 to 1.00, then (1)
the Lender shall promptly notify the Borrower thereof in writing, specifying
the amount of cash which would be required to be pledged under the Security
Agreement so as to result in a Collateral Coverage Ratio of at least 4.00 to
1.00, and (2) if within three Business Days after any such notice is given the
Borrower does not so pledge additional cash sufficient to achieve such
Collateral Coverage Ratio, the Borrower will immediately prepay Loans in an
aggregate principal amount, conforming to the requirements as to the amount of
partial prepayments provided for in section 3.1, at least sufficient result in
a Collateral Coverage Ratio of at least 4.00 to 1.00. Any prepayments of the

Repayments in inverse order of maturity.

(c)	Sales, etc. of Pledged Shares. If at any time the Borrower shall
receive Net Cash Proceeds from (1) any sale, transfer or other disposition by
the Borrower of any Pledged Shares, (2) any dividend or distribution in
connection with a partial or complete liquidation of the issuer of any of the
Pledged Shares, or (3) any transaction involving a merger, consolidation,

shall prepay the principal of the Loans in an aggregate amount, conforming to
the requirements as to the amount of partial prepayments provided for in

prepayments of the Loans pursuant to this section 3.2(c) shall be applied to
the Scheduled Repayments in order of maturity.

(f)	Particular Loans to be Prepaid. With respect to each repayment or
prepayment of Loans required by this section 3.2, the Borrower shall designate
<PAGE>
the Types of Loans which are to be prepaid and the specific Loan(s) to which
such repayment or prepayment is to be made, provided that (i) the Borrower
shall first so designate all Loans that are Prime Rate Loans and Eurodollar
Loans with Interest Periods ending on the date of repayment or prepayment prior
to designating any other Eurodollar Loans for repayment or prepayment, and (ii)
if the outstanding principal amount of a Eurodollar Loan is reduced below the
applicable Minimum Borrowing Amount as a result of any such repayment or
prepayment, then all the remaining principal amount of such Eurodollar Loan
shall be Converted into a Prime Rate Loan. In the absence of a designation by
the Borrower as described in the preceding sentence, the Lender shall, subject
to the above, make such designation in its sole discretion with a view, but no
obligation, to minimize breakage costs owing under section 2.10. Any repayment
or prepayment of Eurodollar Loans pursuant to this section 3.2 shall in all
events be accompanied by such compensation as is required by section 2.10.

3.3.	Method and Place of Payment. Except as otherwise specifically provided
herein, all payments under this Agreement shall be made to the Lender not later
than 12:00 noon (local time at the Payment Office) on the date when due and

lawful money of the United States of America, it being understood that
telephonic notice (confirmed in writing) by the Borrower to the Lender to make
a payment from the funds in the Borrower's account at the Payment Office shall
constitute the making of such payment to the extent of such funds held in such
account. Any payments under this Agreement which are made later than 12:00 noon
(local time at the Payment Office) shall be deemed to have been made on the
next succeeding Business Day. Whenever any payment to be made hereunder shall
be stated to be due on a day which is not a Business Day, the due date thereof
shall be extended to the next succeeding Business Day and, with respect to
payments of principal, interest shall be payable during such extension at the
applicable rate in effect immediately prior to such extension. All payments

SECTION 5.	REPRESENTATIONS AND WARRANTIES.

In order to induce the Lender to enter into this Agreement and to make the Loan
on the Closing Date, the Borrower makes the following representations and
warranties to, and agreements with, the Lender, all of which shall survive the
execution and delivery of this Agreement and the incurrence of the Loan:

5.1.	Organizational Status, etc. Each of the Borrower and its Subsidiaries
(i) is a duly organized or formed and validly existing corporation, partnership
or limited liability company, as the case may be, in good standing under the
laws of the jurisdiction of its formation and has the corporate, partnership or
limited liability company power and authority, as applicable, to own its
property and assets and to transact the business in which it is engaged and
presently proposes to engage, and (ii) has duly qualified and is authorized to
do business in all jurisdictions where it is required to be so qualified except
where the failure to be so qualified would not have a Material Adverse Effect.

5.2.	Subsidiaries.   As of the date hereof, the Borrower has no Subsidiary.


5.3.	Organizational Power and Authority, etc. Each Credit Party has the
corporate or other organizational power and authority to execute, deliver and
carry out the terms and provisions of the Credit Documents to which it is party
and has taken all necessary corporate or other organizational action to
authorize the execution, delivery and performance of the Credit Documents to
which it is party. Each Credit Party has duly executed and delivered each
Credit Document to which it is party and each Credit Document to which it is
party constitutes the legal, valid and binding agreement or obligation of such
Credit Party enforceable in accordance with its terms, except to the extent
that the enforceability thereof may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium or other similar laws generally
affecting creditors' rights and by equitable principles (regardless of whether
enforcement is sought in equity or at law).

<PAGE>
5.4.	No Violation. Neither the execution, delivery and performance by any
Credit Party of the Credit Documents to which it is party nor compliance with
the terms and provisions thereof, nor the consummation of the loan transactions
contemplated therein (i) will contravene any provision of any law, statute,
rule, regulation, order, writ, injunction or decree of any court or
governmental instrumentality applicable to such Credit Party or its properties
and assets, (ii) will conflict with or result in any breach of, any of the
terms, covenants, conditions or provisions of, or constitute a default under,
or result in the creation or imposition of (or the obligation to create or
impose) any Lien (other than the Lien of any Security Document) upon any of the
property or assets of such Credit Party or any of its Subsidiaries pursuant to
the terms of any promissory note, bond, debenture, indenture, mortgage, deed of
trust, credit or loan agreement, or any other material agreement or other
instrument, to which such Credit Party or any of its Subsidiaries is a party or
by which it or any of its property or assets are bound or to which it may be
subject, or (iii) will violate any provision of the articles or certificate of
incorporation, code of regulations, by-laws or other organizational document of
such Credit Party.

5.5.	Governmental Approvals. No order, consent, approval, license,
authorization, or validation of, or filing, recording or registration with, or
exemption by, any foreign or domestic governmental or public body or authority,
or any subdivision thereof, is required to authorize or is required as a
condition to (i) the execution, delivery and performance by any Credit Party of
any Credit Document to which it is a party, or (ii) the legality, validity,
binding effect or enforceability of any Credit Document to which any Credit
Party is a party.

5.6.	Litigation. There are no actions, suits or proceedings pending or, to,
the knowledge of the Borrower, threatened with respect to the Borrower or any
of its Subsidiaries (i) that have, or could reasonably be expected to have, a
Material Adverse Effect, or (ii) which question the validity or enforceability
of any of the Credit Documents, or of any action to be taken by the Borrower or
any of the other Credit Parties pursuant to any of the Credit Documents.

5.7.	Use of Proceeds; Margin Regulations. (a) The proceeds of the Loan made
on the Closing Date shall be used by the Borrower solely to (i) effect payment
by the Borrower of the remaining $20,500,000 capital contribution payable by it
pursuant to the Mandatory Capital Contribution Agreement among the Borrower,
Edison Development Corporation and Plug Power, LLC, entered into in 1999 which
is described in the Registration Statement, and (ii) finance the prior
prepayment by the Borrower of $2,000,000 of its capital contribution
obligations under such Agreement, by providing the Borrower with funds for
working capital requirements and other lawful purposes not inconsistent with
the requirements of this Agreement.

(bi	No part of the proceeds of any Loan will be used directly or indirectly
to purchase or carry Margin Stock, or to extend credit to others for the
purpose of purchasing or carrying any Margin Stock, in violation of any of the
provisions of Regulation T, U or X of the Board of Governors of the Federal
Reserve System.

5.8.	Financial Statements, etc. (a) The Borrower has furnished to the Lender
complete and correct copies of (i) the audited consolidated balance sheets of
the Borrower and its consolidated subsidiaries as of the end of its fiscal
years ended on or nearest to September 30, 1997 and September 30, 1998, and the
related audited consolidated statements of income, stockholders' equity, and
cash flows for the fiscal years then ended, accompanied by the unqualified
report thereon of the Borrower's independent accountants; and (ii) the
<PAGE>
unaudited condensed consolidated balance sheets of the Borrower and its
consolidated subsidiaries as of June 25, 1999, and the related unaudited
condensed consolidated statements of income and of cash flows of the Borrower
and its consolidated subsidiaries for the fiscal quarter or quarters then
ended, as contained in the Form 10-Q Quarterly Report of the Borrower filed
with the SEC for such fiscal quarter. All such financial statements have been
prepared in accordance with GAAP, consistently applied (except as stated
therein), and fairly present the financial position of the Borrower and its
consolidated subsidiaries as of the respective dates indicated and the
consolidated results of their operations and cash flows for the respective
periods indicated, subject in the case of any such financial statements which
are unaudited, to normal audit adjustments, none of which will involve a
Material Adverse Effect. The Borrower and its Subsidiaries did not have, as of
the date of the latest financial statements referred to above, and will not
have as of the Closing Date after giving effect to the incurrence of the Loan
hereunder, any material or significant contingent liability, or liability for
taxes, long-term lease or unusual forward or long-term commitment, that is not
reflected in the foregoing financial statements or the notes thereto in
accordance with GAAP and which in any such case is material in relation to the
business, operations, properties, assets, condition (financial or otherwise) or
prospects of the Borrower and its Subsidiaries, except for the commitments and
other obligations and liabilities incurred in connection with the sale of Ling
Electronics, Inc. and Ling Electronics, Ltd. in October 1999, and the
investment and other commitments made with Satcon Technology Corporation in
October 1999, all as previously publicly announced and described in a Form 8-K
Current Report with respect thereto filed by the Borrower with the SEC
(the"October 1999 Form 8-K").

(b)	Each Credit Party has received consideration which is the reasonable
equivalent value of the obligations and liabilities that it has incurred to the
Lender. Each Credit Party has capital sufficient to carry on its business and
transactions and all business and transactions in which it is about to engage,
is solvent and able to pay its debts as they mature and owns property having a
value, both at fair valuation and at present fair salable value, greater than
the amount required to pay its debts; and no Credit Party is entering into the
Credit Documents with the intent to hinder, delay or defraud its creditors. For
purposes of this section 5.8(b), "debt" means any liability on a claim, and
"claim" means (x) right to payment whether or not such a right is reduced to
judgment, liquidated, unliquidated, fixed, contingent, matured, unmatured,
disputed, undisputed, legal, equitable, secured or unsecured; or (y) right to
an equitable remedy for breach of performance if such breach gives rise to a
payment, whether or not such right to an equitable remedy is reduced to
judgment, fixed, contingent, matured, unmatured, disputed, undisputed, secured
or unsecured.

5.9.	No Material Adverse Change. Since September 30, 1998, there has been no
change in the condition, business or affairs of the Borrower and its
Subsidiaries taken as a whole, or their properties and assets considered as an
entirety, which, individually or in the aggregate, has had or could reasonably
be expected to have, a Material Adverse Effect, other than any changes which
may have been described in the Borrower's October 1999 Form 8-K and the Form
10-Q Quarterly Reports for subsequent fiscal periods which have been filed with
the SEC and copies of which have been delivered to the Lender prior to the date
hereof .


5.10.	Tax Returns and Payments. The Borrower and each of its Subsidiaries has
each filed all federal income tax returns and all other material tax returns,
domestic and foreign, required to be filed by it and has paid all material
<PAGE>
taxes and assessments payable by it which have become due, other than those not
yet delinquent and except for those contested in good faith. The Borrower and
each of its Subsidiaries has established on its books such charges, accruals
and reserves in respect of taxes, assessments, fees and other governmental
charges for all fiscal periods as are required by GAAP. The Borrower knows of
no proposed assessment for additional federal, foreign or state taxes for any
period, or of any basis therefor, which, individually or in the aggregate,
taking into account such charges, accruals and reserves in respect thereof as
the Borrower and its Subsidiaries have made, could reasonably be expected to
have a Material Adverse Effect.

5.11.	Title to Properties, etc. The Borrower and each of its Subsidiaries has
good and marketable title, in the case of real property, and good title (or
valid leaseholds, in the case of any leased property), in the case of all other
property, to all of its properties and assets; and the interests of the
Borrower and each of its Subsidiaries in the properties reflected in the most
recent balance sheet referred to in section 5.8, taken as a whole, were
sufficient, in the judgment of the Borrower, as of the date of such balance
sheet for purposes of the ownership and operation of the businesses conducted
by the Borrower and such Subsidiaries; provided, that it is understood that the
foregoing representation is qualified by the fact and effect of the sale in
October 1999 by Borrower of certain of its then Subsidiaries as described in
the October 1999 Form 8-K.

5.12.	Lawful Operations, etc. Except for known situations or incidents which
are reserved for on the most recent consolidated balance sheet referred to in
section 5.8 or which, if not so reserved, could not reasonably be expected to
have a Material Adverse Effect, the Borrower and each of its Subsidiaries is in
full compliance with all material requirements imposed by law which are
applicable to them, their operations or their properties, whether federal or
state or local, including (without limitation) all Environmental Laws.

5.13.	Compliance with ERISA. Compliance by the Borrower with the provisions
hereof and Loans contemplated hereby will not involve any prohibited
transaction within the meaning of ERISA or section 4975 of the Code. The
Borrower and each of its Subsidiaries, (i) has fulfilled all obligations under
minimum funding standards of ERISA and the Code with respect to each Plan that
is not a Multiemployer Plan or a Multiple Employer Plan, (ii) has satisfied all
respective contribution obligations in respect of each Multiemployer Plan and
each Multiple Employer Plan, (iii) is in compliance in all material respects
with all other applicable provisions of ERISA and the Code with respect to each
Plan, each Multiemployer Plan and each Multiple Employer Plan, and (iv) has not
incurred any liability under the Title IV of ERISA to the PBGC with respect to
any Plan, any Multiemployer Plan, any Multiple Employer Plan, or any trust
established thereunder. No Plan or trust created thereunder has been
terminated, and there have been no Reportable Events, with respect to any Plan
or trust created thereunder or with respect to any Multiemployer Plan or
Multiple Employer Plan, which termination or Reportable Event will or, to the
best of the Borrower's knowledge, could result in the termination of such Plan,
Multiemployer Plan or Multiple Employer Plan and give rise to a material
liability of the Borrower or any ERISA Affiliate in respect thereof. Neither
the Borrower nor any ERISA Affiliate is at the date hereof, or has been at any
time within the two years preceding the date hereof, an employer required to
contribute to any Multiemployer Plan or Multiple Employer Plan, or a
"contributing sponsor" (as such term is defined in section 4001 of ERISA) in
any Multiemployer Plan or Multiple Employer Plan. Neither the Borrower nor any
ERISA Affiliate has any contingent liability with respect to any
post-retirement "welfare benefit plan" (as such term is defined in ERISA)
except as has been disclosed to the Lender in writing.
<PAGE>
5.14.	Intellectual Property, etc. The Borrower and each of its Subsidiaries
has obtained or has the right to use all material patents, trademarks,
servicemarks, trade names, copyrights, licenses and other rights with respect
to the foregoing necessary for the present and planned future conduct of its
business, without any known conflict with the rights of others, except for such
patents, trademarks, servicemarks, trade names, copyrights, licenses and
rights, the loss of which, and such conflicts, which in any such case
individually or in the aggregate would not reasonably be expected to have a
Material Adverse Effect.

5.15.	Year 2000 Computer Matters. 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 Computer Issue" (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
Computer Issue" is not reasonably likely to have a Material Adverse Effect.

5.16.	Investment Company Act, etc. Neither the Borrower nor any of its
Subsidiaries is subject to regulation with respect to the creation or
incurrence of Indebtedness under the Investment Company Act of 1940, as
amended, the Interstate Commerce Act, as amended, the Federal Power Act, as
amended, the Public Utility Holding Company Act of 1935, as amended, or any
applicable state public utility law.

5.17.	Security Interests. Once executed and delivered, and until terminated
in accordance with the terms thereof, each of the Security Documents creates,
as security for the obligations purported to be secured thereby, a valid and
enforceable perfected security interest in and Lien on all of the Collateral
subject thereto from time to time, in favor of the Lender, superior to and
prior to the rights of all third persons and subject to no other Liens. No
filings or recordings are required in order to perfect the security interests
created under any Security Document except for filings or recordings required
in connection with any such Security Document which shall have been made, or
for which satisfactory arrangements have been made, upon or prior to the
execution and delivery thereof. All recording, stamp, intangible or other
similar taxes required to be paid by any person under applicable legal
requirements or other laws applicable to the property encumbered by the
Security Documents in connection with the execution, delivery, recordation,
filing, registration, perfection or enforcement thereof have been paid.

5.18.	True and Complete Disclosure. All factual information (taken as a
whole) heretofore or contemporaneously furnished by or on behalf of the
Borrower or any of its Subsidiaries in writing to the Lender for purposes of or
in connection with this Agreement or any transaction contemplated herein is,
and all other such factual information (taken as a whole) hereafter furnished
by or on behalf of such person in writing to the Lender will be, true and
accurate in all material respects on the date as of which such information is
dated or certified and not incomplete by omitting to state any material fact
necessary to make such information (taken as a whole) not misleading at such
time in light of the circumstances under which such information was provided,
except that any such future information consisting of financial projections
prepared by the Borrower is only represented herein as being based on good
faith estimates and assumptions believed by such persons to be reasonable at
the time made, it being recognized by the Lender that such projections as to


<PAGE>
future events are not to be viewed as facts and that actual results during the
period or periods covered by any such projections may differ materially from
the projected results.


SECTION 6.	AFFIRMATIVE COVENANTS.

The Borrower hereby covenants and agrees that, unless subsequent to the
Effective Date the Lender otherwise consents in writing, the Borrower will from

terminated and the Loans, together with interest, have been paid in full,
comply with the following covenants:

generally accepted auditing standards, that such accountants believe that such
audit provides a reasonable basis for their opinion, and that in their opinion

respects, the consolidated financial position of the Borrower and its
consolidated subsidiaries as at the end of such fiscal year and the
consolidated results of their operations and cash flows for such fiscal year in

of its Subsidiaries to, (i) keep proper books of record and account, in which
full and correct entries shall be made of all financial transactions and the
assets and business of the Borrower or such Subsidiaries, as the case may be,

possession of another person), and to examine (and make copies of or take

request.

6.3.	Insurance. The Borrower will, and will cause each of its Subsidiaries

further, that the Borrower will not be considered to be in default of any of
the provisions of this sentence if the Borrower or any Subsidiary fails to pay
any such amount which, individually or in the aggregate, is immaterial to the
Borrower and its Subsidiaries considered as an entirety.

6.5.	Corporate Franchises. The Borrower will do, and will cause each of its
Subsidiaries to do, or cause to be done, all things necessary to preserve and
keep in full force and effect its corporate or other organizational existence,
rights, authority and franchises, provided that nothing in this section 6.5
shall be deemed to prohibit (i) any transaction permitted by section 7.2; (ii)
the termination of existence of any Subsidiary if (A) the Borrower determines
that such termination is in its best interest and (B) such termination is not
adverse in any material respect to the interests of the Lender as a creditor of
the Borrower; or (iii) the loss of any rights, authorities or franchises if the
loss thereof, in the aggregate, could not reasonably be expected to have a
Material Adverse Effect.

6.6.	Good Repair. The Borrower will, and will cause each of its Subsidiaries
to, ensure that its material properties and equipment used or useful in its
business in whomsoever's possession they may be, are kept in good repair,
working order and condition, normal wear and tear excepted, provided that this
sentence shall not prohibit the Borrower or any Subsidiary from discontinuing
the operation and/or the maintenance of any of its properties if (i) the
Borrower has concluded that such discontinuance is desirable in the overall
conduct of the business of the Borrower and its Subsidiaries considered as an
entirety, and (ii) such discontinuance could not, individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect.

6.7.	Compliance with Statutes, etc. The Borrower will, and will cause each
of its Subsidiaries to, comply, in all material respects, with all applicable
statutes, regulations and orders of, and all applicable restrictions imposed
by, all governmental bodies, domestic or foreign, in respect of the conduct of
its business and the ownership of its property, including (without limitation)
all Environmental Laws, other than those (i) being contested in good faith by
appropriate proceedings, as to which adequate reserves are established to the
extent required under GAAP, and (ii) the noncompliance with which would not
have, and which would not be reasonably expected to have, a Material Adverse
Effect.

at any time after the Closing Date the Borrower has any Material Subsidiary
which (1) is not a party to the Subsidiary Guaranty, and (2) is organized under
the laws of the District of Columbia or one of the States of the United States,
then the Borrower will notify the Lender in writing of such event, identifying
the Subsidiary in question and referring specifically to the rights of the
Lender under this section. The Borrower will, within 30 days following request
therefor from the Lender, cause such Subsidiary to deliver to the Lender (i) if
the Subsidiary Guaranty has not already been executed and delivered, the
Subsidiary Guaranty (as modified, amended or supplemented from time to time in
accordance with the terms thereof and hereof, the "Subsidiary Guaranty"),
substantially in the form attached hereto as Exhibit B-3, or (ii) if the

supplement, reasonably satisfactory in form and substance to the Lender, duly
executed by such Subsidiary, pursuant to which such Subsidiary joins in the
Subsidiary Guaranty as a guarantor thereunder, and (iii) if such Subsidiary is
a corporation, resolutions of the Board of Directors of such Subsidiary,
certified by the Secretary or an Assistant Secretary of such Subsidiary as duly
adopted and in full force and effect, authorizing the execution and delivery of

applicable, as the Lender may reasonably request.

6.9.	Senior Debt. The Borrower will at all times ensure that (i) the claims
of the Lender in respect of the Loans and the Borrower will, with respect to
any Collateral, rank prior to the claims of any other creditor of the Borrower
with respect to the Collateral which arise out of other Debt of the Borrower;
and (ii) any Debt of the Borrower which is subordinated in any manner to the
claims of any secured or unsecured creditor of the Borrower will be
subordinated in like manner to the claims of the Lender in respect of the
Loans.

and after the Effective Date and until such time as the Commitment has been
terminated and the Loans, together with interest, have been paid in full,
comply with the following covenants:

7.1.	Changes in Business. Neither the Borrower nor any of its Subsidiaries
will engage in any business if, as a result, the general nature of the

nature of the business engaged in or contemplated to be engaged in by the
Borrower and its Subsidiaries on the date hereof.

the Borrower under the Credit Documents pursuant to an assumption agreement in
form and substance reasonably satisfactory to the Lender, (ii) no Event of

of the Lender under the Pledge Agreement, the Lender will cooperate with the
Borrower to pre-position appropriate stock certificates with the broker
selected by the Borrower to effect any particular sale.

in the ordinary course of business of and pursuant to the reasonable
requirements of the Borrower's or such Subsidiary's business and upon fair and

against any and all present and future stamp and other similar taxes with
respect to the foregoing matters and save the Lender harmless from and against
any and all liabilities with respect to or resulting from any delay or omission

(c)	The Borrower agrees to indemnify the Lender and its officers,
directors, employees, representatives, agents and Affiliates, and their
respective successors and assigns (collectively, the "Indemnitees") from and
hold each of them harmless against any and all losses, costs, expenses,
liabilities, penalties, fines, claims, damages, costs or expenses reasonably
incurred by any of them as a result of, or arising out of, or in any way
related to, or by reason of

(i)	any investigation, litigation or other proceeding (whether or not the
Lender is a party thereto) related to the entering into and/or performance of
any Credit Document or the use of the proceeds of any Loans hereunder or the
consummation of any transactions contemplated in any Credit Document, other
than any such investigation, litigation or proceeding arising out of
transactions solely involving the assignment by the Lender of all or a portion
of its Loans and Commitment, or the granting of participations therein, as
provided in this Agreement, or arising solely out of any examination of the
Lender by any regulatory or other governmental authority having jurisdiction
over it, or

surface water or groundwater or on the surface or subsurface of any property at
any time owned, leased or operated by the Borrower or any of its Subsidiaries
or any of their respective predecessors in interest, the release, generation,
<PAGE>
storage, transportation, handling or disposal of Hazardous Materials at any
location, whether or not owned or operated by the Borrower or any of its
Subsidiaries, if the Borrower or any such Subsidiary could have or is alleged
to have any responsibility in respect thereof, the non-compliance of any such
property with foreign, federal, state and local laws, regulations and

litigation or other proceeding (but excluding any such losses, liabilities,
claims, damages or expenses to the extent incurred by reason of the gross
negligence or willful misconduct of the person to be indemnified or of any
other Indemnitee who is such person or an Affiliate of such person). To the
extent that the undertaking to indemnify, pay or hold harmless any person set
forth in the preceding sentence may be unenforceable because it is violative of
any law or public policy, the Borrower shall make the maximum contribution to
the payment and satisfaction of each of the indemnified liabilities which is
permissible under applicable law.

9.2.	Right of Setoff. In addition to any rights now or hereafter granted
under applicable law or otherwise, and not by way of limitation of any such

presentment, demand, protest or other notice of any kind to the Borrower or to
any other person, any such notice being hereby expressly waived, to set off and
to appropriate and apply any and all deposits (general or special) and any
other Debt at any time held or owing by the Lender (including, without
limitation, by branches and agencies of the Lender wherever located) to or for
the credit or the account of the Borrower against and on account of the
obligations and liabilities of the Borrower to the Lender under this Agreement
or under any of the other Credit Documents, including, without limitation, all
other claims of any nature or description arising out of or connected with this
Agreement or any other Credit Document, irrespective of whether or not the
Lender shall have made any demand hereunder and although said obligations,
liabilities or claims, or any of them, shall be contingent or unmatured.

9.3.	Notices. Except as otherwise expressly provided herein, all notices and
other communications provided for hereunder shall be in writing (including
telegraphic, telex, facsimile and e-mail transmission or cable communication)
and mailed, telegraphed, telexed, transmitted, cabled or delivered, if to the

Notice Office; or at such other address as shall be designated by any party in
a written notice to the other parties hereto. All such notices and
communications shall be mailed, telegraphed, telexed, transmitted, or cabled or
sent by overnight courier, and shall be effective when received.

9.4.	Benefit of Agreement. (a) General. This Agreement shall be binding upon
and inure to the benefit of and be enforceable by the parties hereto and their
respective successors and assigns, provided that the Borrower may not assign or
transfer any of its rights or obligations hereunder without the prior written
consent of the Lender, and, provided, further, that any assignment by the
Lender of its rights and obligations hereunder shall be effected in accordance
with section 9.4(c).

(b)	Participations. Notwithstanding the foregoing, the Lender may at any
time grant participations in any of its rights hereunder or under any of the
<PAGE>
Notes to an Affiliate of the Lender which is a commercial bank, financial
institution or other "accredited investor" (as defined in SEC Regulation D), or
(y) one or more other commercial banks, financial institutions or other
"accredited investors" as so defined, provided that in the case of any such
participation, (i) the participant shall not have any rights under this
Agreement or any of the other Credit Documents, including rights of consent,
approval or waiver (the participant's rights against the Lender in respect of
such participation to be those which are customary and are set forth in the
agreement executed by the Lender in favor of the participant relating thereto);
(ii) the Lender's obligations under this Agreement (including, without
limitation, its Commitment hereunder) shall remain unchanged; (iii) the Lender
shall remain solely responsible to the other parties hereto for the performance
of such obligations; (iv) the Lender shall remain the holder of any Note for
all purposes of this Agreement; and (v) the Borrower shall continue to deal
solely and directly with the selling Lender in connection with the Lender's
rights and obligations under this Agreement.

(c)	Assignments by Lender. Notwithstanding the foregoing, the Lender may
assign all of its Loans and Commitment, and its rights and obligations
hereunder, to (i) an Affiliate of the Lender which is a commercial bank,
financial institution or other "accredited investor" (as defined in SEC
Regulation D), or (ii) another commercial bank, financial institution or other
"accredited investor" (as defined in SEC Regulation D) which (if no Event of
Default is in existence) is reasonably acceptable to the Borrower. Upon any
such assignment the assigning Lender shall be relieved of its obligations
hereunder with respect to its assigned Commitment. Nothing in this section
9.4(c) shall prevent or prohibit the Lender from pledging its Note or Loans to
a Federal Reserve Bank in support of borrowings made by the Lender from such
Federal Reserve Bank.

(d)	No SEC Registration or Blue Sky Compliance. Notwithstanding any other
provisions of this section 9.4, no transfer or assignment of the interests or
obligations of the Lender hereunder or any grant of participation therein shall
be permitted if such transfer, assignment or grant would require the Borrower
to file a registration statement with the SEC or to qualify the Loans under the
"Blue Sky" laws of any State.

(e)	Representations of Lender. The Lender initially party to this Agreement
hereby represents, and each person that became the Lender pursuant to an
assignment permitted by this section 9.4 will, upon its becoming party to this
Agreement, represent that it is a commercial lender, other financial
institution or other "accredited" investor (as defined in SEC Regulation D)
which makes or acquires loans in the ordinary course of its business and that
it will make or acquire Loans for its own account in the ordinary course of
such business, provided that subject to the preceding sections 9.4(b) and (c),
the disposition of any promissory notes or other evidences of or interests in
Indebtedness held by the Lender shall at all times be within its exclusive
control.

9.5.	No Waiver: Remedies Cumulative. No failure or delay on the part of the
Lender in exercising any right, power or privilege hereunder or under any other
Credit Document and no course of dealing between the Borrower and the Lender
shall operate as a waiver thereof; nor shall any single or partial exercise of
any right, power or privilege hereunder or under any other Credit Document
preclude any other or further exercise thereof or the exercise of any other
right, power or privilege hereunder or thereunder. The rights and remedies
herein expressly provided are cumulative and not exclusive of any rights or
remedies which the Lender would otherwise have. No notice to or demand on the
Borrower in any case shall entitle the Borrower to any other or further notice
<PAGE>
or demand in similar or other circumstances or constitute a waiver of the
rights of the Lender to any other or further action in any circumstances
without notice or demand.

9.6.	Independence of Covenants. All covenants hereunder shall be given
independent effect so that if a particular action, event, condition or
circumstance is not permitted by any of such covenants, the fact that it would
be permitted by an exception to, or would otherwise be within the limitations
or restrictions of, another covenant, shall not avoid the occurrence of a
Default or an Event of Default if such action is taken or event, condition or
circumstance exists.


9.7.	Governing Law; Submission to Jurisdiction; Venue; Waiver of Jury Trial.
(a) THIS AGREEMENT AND THE OTHER CREDIT DOCUMENTS AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HEREUNDER AND THEREUNDER SHALL BE CONSTRUED IN
ACCORDANCE WITH AND BE GOVERNED BY THE LAW OF THE STATE OF NEW YORK. TO THE
FULLEST EXTENT PERMITTED BY LAW, THE BORROWER HEREBY UNCONDITIONALLY AND
IRREVOCABLY WAIVES ANY CLAIM TO ASSERT THAT THE LAW OF ANY JURISDICTION OTHER
THAN THE STATE OF NEW YORK GOVERNS THIS AGREEMENT OR ANY OF THE OTHER CREDIT
DOCUMENTS. Any legal action or proceeding with respect to this Agreement or any
other Credit Document may be brought in the Supreme Court of Albany County, New
York, or of the United States for the Northern District of New York, and, by
execution and delivery of this Agreement, the Borrower hereby irrevocably
accepts for itself and in respect of its property, generally and
unconditionally, the jurisdiction of the aforesaid courts. The Borrower hereby
further irrevocably consents to the service of process out of any of the
aforementioned courts in any such action or proceeding by the mailing of copies
thereof by registered or certified mail, postage prepaid, to the Borrower at
its address for notices pursuant to section 9.3, such service to become
effective 30 days after such mailing or at such earlier time as may be provided
under applicable law. Nothing herein shall affect the right of the Lender to
serve process in any other manner permitted by law or to commence legal
proceedings or otherwise proceed against the Borrower in any other
jurisdiction.

(b)	The Borrower hereby irrevocably waives any objection which it may now
or hereafter have to the laying of venue of any of the aforesaid actions or
proceedings arising out of or in connection with this Agreement or any other
Credit Document brought in the courts referred to in section 9.7(a) above and
hereby further irrevocably waives and agrees not to plead or claim in any such
court that any such action or proceeding brought in any such court has been
brought in an inconvenient forum.

(c)	EACH OF THE PARTIES TO THIS AGREEMENT HEREBY IRREVOCABLY WAIVES ALL
RIGHT TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT
OF OR RELATING TO THIS AGREEMENT, THE OTHER CREDIT DOCUMENTS OR THE
TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

9.8.	Counterparts. This Agreement may be executed in any number of
counterparts and by the different parties hereto on separate counterparts, each
of which when so executed and delivered shall be an original, but all of which
shall together constitute one and the same agreement. A set of counterparts
executed by all the parties hereto shall be lodged with the Borrower and the
Lender.

9.9.	Effectiveness; Integration. This Agreement shall become effective on
the date (the "Effective Date") on which the Borrower and the Lender shall have
signed a copy hereof (whether the same or different copies) and shall have
<PAGE>
delivered the same to the Lender at the Notice Office. This Agreement, the
other Credit Documents and any separate letter agreements with respect to fees
payable to the Lender, constitute the entire contract among the parties
relating to the subject matter hereof and thereof and supersede any and all
previous agreements and understandings, oral or written, relating to the
subject matter hereof or thereof.

9.10.	Headings Descriptive. The headings of the several sections and other
portions of this Agreement are inserted for convenience only and shall not in
any way affect the meaning or construction of any provision of this Agreement.


9.11.	Amendment or Waiver. Neither this Agreement, any of the other Credit
Documents, nor any terms hereof or thereof, may be amended, changed, waived,
discharged or terminated unless such amendment, change, waiver, discharge or
termination is in writing signed by the Borrower (or other appropriate Credit
Party) and the Lender.

9.12.	Survival of Indemnities. All indemnities set forth herein including,
without limitation, in section 2.9, 2.10 and 9.1 shall survive the execution
and delivery of this Agreement and the making and prepayment or repayment of
the Loans.

9.13.	Domicile of Loans. The Lender may transfer and carry its Loans at, to
or for the account of any branch office, subsidiary or Affiliate of the Lender,
provided that the Borrower shall not be responsible for any additional costs
arising under section 2.9 resulting from any such transfer.

9.14.	Confidentiality. The Lender shall hold all non-public information
obtained pursuant to the requirements of this Agreement in accordance with its
customary procedure for handling confidential information of this nature and in
accordance with safe and sound banking practices. Notwithstanding the
foregoing, the Lender may in any event make disclosures of, and furnish copies
of such information (i) when reasonably required by any bona fide transferee or
participant in connection with the contemplated transfer of any Loans or
Commitment or participation therein (provided that each such prospective
transferee and/or participant shall execute an agreement for the benefit of the
Borrower with such prospective transferor Lender and/or participant containing
provisions substantially identical to those contained in this section 9.14);
(ii) to its parent corporation or corporations and its and their Affiliates,
and to its and their auditors and attorneys; and (iii) as required or requested
by any governmental agency or representative thereof or pursuant to legal
process, provided that, unless specifically prohibited by applicable law or
court order, the Lender shall notify the Borrower of any request by any
governmental agency or representative thereof (other than any such request in
connection with an examination of the financial condition of the Lender by such
governmental agency) for disclosure of any such non-public information prior to
disclosure of such information. In no event shall the Lender be obligated or
required to return any materials furnished by or on behalf of the Borrower or
any of its Subsidiaries. The Borrower hereby agrees that the failure of the
Lender to comply with the provisions of this section 9.14 shall not relieve the
Borrower of any of its obligations to the Lender under this Agreement and the
other Credit Documents.

9.15.	General Limitation of Liability. No claim may be made by or through the
Borrower or any of its Affiliates against the Lender or its directors,
officers, employees, attorneys, agents or Affiliates, and no claim may be made
by the Lender against the Borrower, for any damages other than actual
compensatory damages in respect of any claim for breach of contract or any
<PAGE>
other theory of liability arising out of or related to the transactions
contemplated by this Agreement or any of the other Credit Documents, or any
act, omission or event occurring in connection therewith; and the Borrower and
the Lender each hereby, to the fullest extent permitted under applicable law,
waives, releases and agrees not to sue or counterclaim upon any such claim for
any special, consequential or punitive damages, whether or not accrued and
whether or not known or suspected to exist in its favor.

9.16.	No Duty. All attorneys, accountants, appraisers, consultants and other
professional persons (including the firms or other entities on behalf of which
any such person may act) retained by the Lender with respect to the
transactions contemplated by the Credit Documents shall have the right to act
exclusively in the interest of the Lender, and shall have no duty of
disclosure, duty of loyalty, duty of care, or other duty or obligation of any
type or nature whatsoever to the Borrower, to any of its Subsidiaries or
Affiliates, or to any other person, with respect to any matters within the
scope of such representation or related to their activities in connection with
such representation. The Borrower agrees, on behalf of itself and its
Subsidiaries, not to assert any claim or counterclaim against any such persons
with regard to such matters, all such claims and counterclaims, now existing or
hereafter arising, whether known or unknown, foreseen or unforeseeable, being
hereby waived, released and forever discharged.

9.17.	Lender Not Fiduciary to Borrower, etc. The relationship among the
Borrower and its Subsidiaries and Affiliates, on the one hand, and the Lender,
on the other hand, is solely that of debtor and creditor, and the Lender has no
fiduciary or other special relationship with the Borrower and/or any of its
Subsidiaries and Affiliates, and no term or provision of any Credit Document,
no course of dealing, no written or oral communication, or other action, shall
be construed so as to deem such relationship to be other than that of debtor
and creditor.

9.18.	Survival of Representations and Warranties. All representations and
warranties herein shall survive the making of Loans hereunder, the execution
and delivery of this Agreement, the Notes and any other documents the forms of
which are attached as Exhibits hereto, the issue and delivery of the Notes, any
disposition thereof by any holder thereof, and any investigation made by the
Lender or on its behalf. All statements contained in any certificate or other
document delivered to the Lender by or on behalf of the Borrower or any of its
Subsidiaries or Affiliates pursuant hereto or otherwise specifically for use in
connection with the transactions contemplated hereby shall constitute
representations and warranties by the Borrower hereunder, made as of the
respective dates specified therein or, if no date is specified, as of the
respective dates furnished to the Lender.

IN WITNESS WHEREOF, each of the parties hereto has caused one or more
counterparts of this Agreement to be duly executed and delivered as of the
date first above written.

	            FORM OF OPINION OF COUNSEL TO THE BORROWER

							____________ __, 1999
KeyBank National Association
66 South Pearl Street
Albany, New York 12207

Re:	$22,500,000 Credit Agreement,
        dated as of November 1, 1999,
        with Mechanical Technology Incorporated

Ladies and Gentlemen:

We have acted as special counsel to Mechanical Technology Incorporated, a New
York corporation (the "Borrower"), in connection with (i) the execution and
delivery of the Credit Agreement, dated as of November 1, 1999 (the "Credit
Agreement"), between the Borrower and KeyBank National Association (the
"Lender"), and (ii) the transactions contemplated thereby. Unless otherwise
indicated, capitalized terms used herein but not otherwise defined herein shall
have the respective meanings set forth in the Credit Agreement. This opinion
letter is delivered by us to you at the request of the Borrower in accordance
with the requirements of section 4.8 of the Credit Agreement.

As such special counsel, we have examined originals or copies, certified or
otherwise identified to our satisfaction, of such documents, records and
matters of law as we have considered necessary as a basis for the opinions set
forth herein, including without limitation the following:

(a)	the Credit Agreement;

(b)	the Note delivered today pursuant to the Credit Agreement;

(c)	the Security Agreement;

(d)	the Account Control Agreement; and

(e)	the Pledge Agreement.

The documents referred to in clauses (a) through (e) above are herein sometimes
referred to as the "Credit Documents" and the documents referred to in clauses
(c), (d) and (e) above are herein sometimes referred to as the "Security
Documents".


<PAGE>
In our examination we have assumed the genuineness of all signatures (other
than as to the Borrower), the authenticity of all documents submitted to us as
originals, the conformity to original documents of all documents submitted to
us as certified or photostatic copies and the authenticity of the originals of
such copies. As to questions of fact not independently verified by us we have
relied, to the extent we deemed appropriate, upon representations and
certificates of officers of the Borrower, public officials and other
appropriate persons. All assumptions and statements of reliance as to factual
matters herein have been made without any independent investigation or
verification on our part except to the extent otherwise expressly stated, and
we express no opinion with respect to the subject matter or accuracy of such
assumptions or items relied upon. We have also assumed the due authorization,
execution and delivery of the Credit Documents on the part of the Lender, and
the legality, validity, binding effect on, and enforceability of the Credit
Documents against, the Lender. This opinion letter is subject to, and is to be
construed in accordance with, the principles and limitations set forth in the
Special Report by the TriBar Opinion Committee, U.C.C. Security Interest
Opinions, 49 Bus. Law. 362 (1993).

We understand that you have considered the applicability of fraudulent transfer
laws to the transactions contemplated by the Credit Documents, as to which laws
we express no opinion, and have satisfied yourself with respect thereto.

Our examination of matters of law in connection with the opinions expressed
herein has been limited to the federal laws of the United States and the laws
of the State of New York and, accordingly, no opinions expressed herein shall
be deemed to cover any other laws.

We have neither examined nor requested an examination of the indices or records
of any court or governmental or other agency, authority, instrumentality or
entity, nor have we made inquiry of any person or entity, except as expressly
set forth in this opinion letter. In addition, we have not independently
verified or investigated the accuracy or completeness of any factual
information and, because the scope of our examination did not include such
verification, we assume no responsibility for the accuracy or completeness of
any such information.

As used herein, "to our knowledge" shall mean to the actual knowledge of the
lawyers who have been actively involved in the negotiation of the Credit
Documents and the lawyers in our firm who are the current primary contacts for
the Borrower at the firm.

Based upon the foregoing and subject to the qualifications, assumptions and
limitations contained in this opinion letter, we are of the opinion that:

1.	Corporate Status, etc. The Borrower (i) is a validly existing
corporation under the laws of the jurisdiction of its formation and has the
corporate power and authority to own its property and assets and to transact
the business in which it is engaged and presently proposed to engage and (ii)
to our knowledge, is duly qualified and is authorized to do business and is in
good standing in each jurisdiction where it is required to be so qualified
except where the failure to be so qualified would not have a Material Adverse
Effect.

2.	Subsidiaries. To our knowledge, the Borrower has no Subsidiary other
than as described in section 5.2 of the Credit Agreement.



<PAGE>
3.	Corporate Power and Authority, etc. The Borrower has the corporate
power and authority to execute, deliver and carry out the terms and provisions
of the Credit Documents to which it is a party and has taken all necessary
corporate action to authorize the execution, delivery and performance of the
Credit Documents to which it is a party.

4.	Credit Documents. The Borrower has duly executed and delivered each
Credit Document to which it is a party and each such Credit Document to which
it is a party constitutes the legal, valid and binding agreement or obligation
of the Borrower enforceable against it in accordance with its terms, except to
the extent that the enforceability thereof may be limited by (i) applicable
bankruptcy, insolvency, reorganization, fraudulent transfer, moratorium or
similar laws, and related judicial doctrines, from time to time in effect
affecting creditors' rights and remedies generally, (ii) general principles of
equity (including, without limitation, standards of materiality, good faith,
fair dealing and reasonableness, equitable defenses and limits on the
availability of equitable remedies), whether such principles are considered in
a proceeding at law or in equity, and (iii) the qualification that certain
other provisions of such Credit Documents may be unenforceable in whole or in
part under the laws (including judicial decisions) of the State of New York or
other applicable jurisdictions, but the inclusion of such provisions does not
affect the validity as against the Borrower of any of such Credit Documents as
a whole, and such Credit Documents contain adequate provisions for enforcing
payment of the obligations governed or secured thereby and for the realization
of the principal rights and benefits afforded thereby, subject to the other
qualifications and limitations contained in this opinion letter.

5.	No Violation. Neither the execution, delivery or performance by the
Borrower of the Credit Documents to which it is a party nor compliance with the
terms and provisions thereof, (i) will contravene any provision of any State of
New York or United States federal law, statute, rule, regulation (including,
without limitation, Regulations T, U and X of the Board of Governors of the
Federal Reserve System), or, to our knowledge, any order, writ, injunction or
decree of any court or governmental instrumentality applicable to the Borrower
or its properties and assets, (ii) will conflict or result in any breach of,
any of the terms, covenants, conditions or provisions of, or constitute a
default under, or result in the creation or imposition of (or the obligation to
create or impose) any Lien (other than the Liens created pursuant to the
Security Documents) upon any of the property or assets of the Borrower pursuant
to the terms of any material indenture, mortgage, deed of trust, agreement or
other instrument of which we have knowledge to which the Borrower is a party or
by which it or any of its property or assets are bound or to which it may be
subject or (iii) will violate any provision of the charter or by-laws of the
Borrower.

6.	Governmental Approvals. No order, consent, approval, license,
authorization, or validation of, or filing, recording or registration with, or
exemption by, any New York or United States federal governmental or public body
or authority, is required to authorize or is required as a condition to (i) the
execution, delivery and performance by the Borrower of any Credit Document to
which it is a party, or (ii) the legality, validity, binding effect or
enforceability as against the Borrower of any such Credit Document.

7.	Litigation. To our knowledge, there are no actions, suits or
proceedings pending or, to, our knowledge, threatened with respect to the
Borrower or any of its Subsidiaries (i) that have, or could reasonably be
expected to have, a Material Adverse Effect, or (ii) which question the


<PAGE>
validity or enforceability of any of the Credit Documents, or of any action to
be taken by the Borrower pursuant to any of the Credit Documents to which it is
a party.

8.	Investment Company Act, etc. The Borrower is not subject to regulation
with respect to the creation or incurrence of Indebtedness under the Investment
Company Act of 1940, as amended, the Interstate Commerce Act, as amended, the
Federal Power Act, as amended, the Public Utility Holding Company Act of 1935,
as amended, or any applicable state public utility law.

9.	Pledged Shares. The Pledge Agreement, together with delivery of the
certificates representing the shares of stock of the Company identified on
Schedule I to the Pledge Agreement (the "Pledged Shares") to the Collateral
Agent in the State of New York, creates in favor of the Lender, as security for
the Secured Obligations (as defined in the Pledge Agreement), a perfected
security interest under the Uniform Commercial Code of the State of New York in
the Pledged Shares. Assuming the Lender acquires its interest in the Pledged
Shares in good faith and without notice of any adverse claim, and that each
certificate for any of the Pledged Shares is indorsed in the name of the Lender
or in blank (either on such certificate or in a separate stock power related
thereto), the Lender will acquire its security interest in the Pledged Shares
free of any adverse claims. No filings or recordings are required under the
Uniform Commercial Code of the State of New York in order to perfect the
security interest created under the Pledge Agreement with respect to such
Pledged Shares.

				*  *  *  *  *

The opinions set forth above are subject to the following assumptions,
qualifications and limitations:

	[to be completed
	in a manner acceptable
	to the Lender]


This opinion letter is being furnished only to the addressee and is solely for
its benefit and the benefit of its participants and assigns in connection with
the transactions contemplated by the Credit Documents. This opinion letter may
not be relied upon for any other purpose, or relied upon by any other person,
firm or corporation for any purpose, without our prior written consent.

Very truly yours,

(the "Membership Interests"). Proceeds of the Loans incurred by the Pledgor
under the Credit Agreement, in the amount of $20,500,000, are being used to
make a capital contribution to Plug Power, LLC in exchange for additional
Membership Interests. The balance of the proceeds of the Loans under the Credit
Agreement are being used to finance a $2,000,000 capital contribution which the
Pledgor recently made in Plug Power, LLC in exchange for additional Membership
Interests.

(3)	After the execution and delivery of this Agreement, and pursuant to a
merger agreement between Plug Power, LLC and Plug Power Inc., a Delaware
corporation (herein, togetherwith its successors and assigns, the "Company"),
the Membership Interests owned by the Pledgor will be converted into the shares
(the "Pledged Shares") of stock described in Schedule I hereto and issued by
the Company.

(4)	It is a condition precedent to the making of Loans by the Lender under
the Credit Agreement that the Pledgor shall have made the pledge contemplated
by this Agreement.

NOW, THEREFORE, in consideration of the premises and in order to induce the
Lender to make Loans under the Credit Agreement, the Pledgor hereby agrees as
follows:

1.	Pledge. The Pledgor hereby pledges to the Lender, and grants to the
Lender a security interest in, the following (the "Pledged Collateral"):

(a)	the Membership Interests owned by the Pledgor, the Pledged Shares into
which such Membership Interests will be converted upon the merger of Plug
Power, LLC into the Company, as described above, and the certificates
representing the Pledged Shares, and all dividends, cash, instruments and other
property from time to time received, receivable or otherwise distributed in
respect of or in exchange for any or all of the Pledged Shares;

(b)	all additional shares of stock of any issuer of the Pledged Shares from
time to time acquired by the Pledgor in any manner, and the certificates
representing such additional shares, and all dividends, cash, instruments and
other property from time to time received, receivable or otherwise distributed
in respect of or in exchange for any or all of such shares; and

(c)	all proceeds of any and all of the foregoing Collateral (including,
without limitation, proceeds that constitute property of the types described
above).
<PAGE>
2.	Security for Secured Obligations. This Agreement secures the payment of
(i) all obligations of the Borrower now or hereafter existing under the Credit
Agreement and the Note, whether for principal, interest, fees, expenses or
otherwise, (ii) all obligations of the Pledgor now or hereafter existing under
this Agreement, and (iii) all obligations of the Borrower now or hereafter
existing in favor of the Lender or any of its Affiliates which the Lender may
from time to time designate in writing to the Pledgor as being entitled to the
benefits of the security hereof (all such obligations of the Borrower referred
to in this section 2 being the "Secured Obligations"). Without limiting the
generality of the foregoing, this Agreement secures the payment of all amounts
which constitute part of the Secured Obligations and would be owed by the
Borrower but for the fact that they are unenforceable or not allowable due to
the existence of a bankruptcy, reorganization or similar proceeding involving
the Borrower.

3.	Delivery of Pledged Collateral; Removal of Legends; Use of Securities
Account. (a) The Pledgor shall instruct the Company and its transfer agent to
physically deliver directly to the Lender all certificates for the Pledged
Shares which are issuable to the Pledgor upon conversion of the Membership
Interests owned by the Pledgor into the Pledged Shares in connection with the
merger of Plug Power, LLC into the Company as described above. All certificates
or instruments representing or evidencing the Pledged Collateral shall be
delivered to and held by or on behalf of the Lender pursuant hereto and shall
be in suitable form for transfer by delivery, or shall be accompanied by duly
executed instruments of transfer or assignment in blank, all in form and
substance satisfactory to the Lender. The Lender shall have the right, in its
discretion, at any time during the continuance of an Event of Default and
without notice to the Pledgor, to transfer to or to register in the name of the
Lender or any of its nominees any or all of the Pledged Collateral, subject
only to the revocable rights specified in section 6(a). In addition, the Lender
shall have the right at any time to exchange certificates or instruments
representing or evidencing Pledged Collateral for certificates or instruments
of smaller or larger denominations.

(b)	If any Pledged Collateral is subject to any contractual restriction on
transfer arising under any agreement to which the Pledgor is a party with the
issuer, other shareholders and/or any underwriters, and any certificate or
certificates for such Pledged Collateral contain a legend which makes reference
to such restrictions, the Pledgor will, from time to time and as promptly as
circumstances permit, take all such actions as are within its power to request
and obtain the removal of such legend from certificates for the maximum number
of shares as to which it is entitled to have such legend removed.

(c)	If after the date hereof any or all of the Pledged Collateral may be
held in book entry form and the Pledgor desires that such Pledged Collateral be
held in such form in an account which the Pledgor has with a broker which is a
member firm of the National Association of Securities Dealers, then the Lender
will cooperate with the Pledgor in transferring such Pledged Collateral to such
account, provided that there is in place an "account control agreement"
reasonably satisfactory to the Lender which is sufficient to perfect its
security interest in the Pledged Collateral held in such account and all
proceeds thereof.

4.	Representations and Warranties. The Pledgor represents and warrants
that upon completion of the merger of Plug Power, LLC into the Company as
described above:

(a)	The Pledged Shares will have been duly authorized and validly issued
and will be fully paid and non-assessable.
<PAGE>
(b)	The Pledgor will be the legal and beneficial owner of the Pledged
Collateral free and clear of any lien, security interest, option or other
charge or encumbrance except for the security interest created by this
Agreement.

(c)	The pledge of the Pledged Shares pursuant to this Agreement will create
a valid and perfected first priority security interest in the Pledged
Collateral, securing the payment of the Secured Obligations.

(d)	No consent of any other person or entity and no authorization,
approval, or other action by, and no notice to or filing with, any governmental
authority or regulatory body is required (i) for the pledge by the Pledgor of
the Pledged Collateral pursuant to this Agreement or for the execution,
delivery or performance of this Agreement by the Pledgor, (ii) for the
perfection or maintenance of the security interest created hereby (including
the first priority nature of such security interest) or (iii) for the exercise
by the Lender of the voting or other rights provided for in this Agreement or
the remedies in respect of the Pledged Collateral pursuant to this Agreement
(except as may be required in connection with any disposition of any portion of
the Pledged Collateral by laws affecting the offering and sale of securities
generally).

(e)	The Pledged Shares identified on Schedule I represent all of the equity
interests in the issuer of the Pledged Shares which are owned by the Borrower
or any of its Subsidiaries as of the date of completion of the merger of Plug
Power, LLC into the Company. The Pledged Shares constitute as of such date the
percentage of the issued and outstanding shares of stock of the issuer thereof
indicated on Schedule I.

(f)	There are no conditions precedent to the effectiveness of this
Agreement that have not been satisfied or waived.

(g)	The Pledgor has, independently and without reliance upon the Lender and
based on such documents and information as it has deemed appropriate, made its
own credit analysis and decision to enter into this Agreement.

5.	Further Assurances. The Pledgor agrees that at any time and from time
to time, at the expense of the Pledgor, the Pledgor will promptly execute and
deliver all further instruments and documents, and take all further action,
that may be necessary or desirable, or that the Lender may reasonably request,
in order to perfect and protect any security interest granted or purported to
be granted hereby or to enable the Lender to exercise and enforce its rights
and remedies hereunder with respect to any Pledged Collateral.

6.	Voting Rights; Dividends; etc. (a) So long as no Event of Default shall
have occurred and be continuing:

(i)	The Pledgor shall be entitled to exercise or refrain from exercising
any and all voting and other consensual rights pertaining to the Pledged
Collateral or any part thereof for any purpose not inconsistent with the terms
of this Agreement or the Credit Agreement; provided, however, that the Pledgor
shall not exercise or refrain from exercising any such right if, in the
Lender's judgment, such action would have a material adverse effect on the
value of the Pledged Collateral or any part thereof, and, provided, further,
that the Pledgor shall give the Lender at least five days' written notice of
the manner in which it intends to exercise, or the reasons for refraining from
exercising, any such right.


<PAGE>
(ii)	The Pledgor shall be entitled to receive and retain any and all
dividends and distributions paid in respect of the Pledged Collateral,
provided, however, that any and all


(A)	dividends and distributions paid or payable other than in cash in
respect of, and instruments and other property received, receivable or
otherwise distributed in respect of, or in exchange for, and Pledged
Collateral, and

(B)	dividends and other distributions paid or payable in cash in respect of
any Pledged Collateral in connection with a partial or total liquidation or
dissolution or in connection with a reduction of capital, capital surplus or
paid-in-surplus,

shall be, and shall be forthwith delivered to the Lender to hold as, Pledged
Collateral and shall, if received by the Pledgor, be received in trust for the
benefit of the Lender, be segregated from the other property or funds of the
Pledgor, and be forthwith delivered to the Lender as Pledged Collateral in the
same form as so received (with any necessary indorsement or assignment).

(iii)	The Lender shall execute and deliver (or cause to be executed and
delivered) to the Pledgor all such proxies and other instruments as the Pledgor
may reasonably request for the purpose of enabling the Pledgor to exercise the
voting and other rights which it is entitled to exercise pursuant to paragraph
(i) above and to receive the dividends or distributions which it is authorized
to receive and retain pursuant to paragraph (ii) above.

(b)	Upon the occurrence and during the continuance of an Event of Default:

(i)	All rights of the Pledgor (x) to exercise or refrain from exercising
the voting and other consensual rights which it would otherwise be entitled to
exercise pursuant to section 6(a)(i) shall, upon notice to the Pledgor by the
Lender, cease and (y) to receive the dividends and distributions which it would
otherwise be authorized to receive and retain pursuant to section 6(a)(ii)
shall automatically cease, and all such rights shall thereupon become vested in
the Lender who shall thereupon have the sole right to exercise or refrain from
exercising such voting and other consensual rights and to receive and hold as
Pledged Collateral such dividends and distributions.

(ii)	All dividends and distributions which are received by the Pledgor
contrary to the provisions of paragraph (i) of this section 6(b) shall be
received in trust for the benefit of the Lender, shall be segregated from other
funds of the Pledgor and shall be forthwith paid over to the Lender as Pledged
Collateral in the same form as so received (with any necessary indorsement).

7.	Transfers and Other Liens. The Pledgor agrees that it will not (i)
sell, assign (by operation of law or otherwise) or otherwise dispose of, or
grant any option with respect to, any of the Pledged Collateral, except for
sales of the Pledged Collateral made in accordance with the provisions of
section 7.2(c) of the Credit Agreement; or (ii) create or permit to exist any
lien, security interest, option or other charge or encumbrance upon or with
respect to any of the Pledged Collateral, except for the security interest
under this Agreement.

8.	Lender Appointed Attorney-in-Fact. The Pledgor hereby appoints the
Lender the Pledgor's attorney-in-fact, with full authority in the place and
stead of the Pledgor and in the name of the Pledgor or otherwise, from time to
time in the Lender's discretion to take any action and to execute any
<PAGE>
instrument which the Lender may deem necessary or advisable to accomplish the
purposes of this Agreement (subject to the rights of the Pledgor under section
6), including, without limitation, to receive, indorse and collect all
instruments made payable to the Pledgor representing any dividend[, interest
payment] or other distribution in respect of the Pledged Collateral or any part
thereof and to give full discharge for the same.

9.	Lender May Perform. If the Pledgor fails to perform any agreement
contained herein, the Lender may itself perform, or cause performance of, such
agreement, and the expenses of the Lender incurred in connection therewith
shall be payable by the Pledgor under section 13.

10.	The Lender's Duties. The powers conferred on the Lender hereunder are
solely to protect its interest in the Pledged Collateral and shall not impose
any duty upon it to exercise any such powers. Except for the safe custody of
any Pledged Collateral in its possession and the accounting for moneys actually
received by it hereunder, the Lender shall have no duty as to any Pledged
Collateral, as to ascertaining or taking action with respect to calls,
conversions, exchanges, maturities, tenders or other matters relative to any
Pledged Collateral, whether or not the Lender has or is deemed to have
knowledge of such matters, or as to the taking of any necessary steps to
preserve rights against any parties or any other rights pertaining to any
Pledged Collateral. The Lender shall be deemed to have exercised reasonable
care in the custody and preservation of any Pledged Collateral in its
possession if such Pledged Collateral is accorded treatment substantially equal
to that which the Lender accords its own property.

11.	Remedies upon Default. If any Event of Default shall have occurred and
be continuing:

(a)	The Lender may exercise in respect of the Pledged Collateral, in
addition to other rights and remedies provided for herein or otherwise
available to it, all the rights and remedies of a secured party on default
under the Uniform Commercial Code in effect in the State of New York at that
time (the "Code") (whether or not the Code applies to the affected Collateral),
and may also, without notice except as specified below, sell the Pledged
Collateral or any part thereof in one or more parcels at public or private
sale, at any exchange, broker's board or at any of the Lender's offices or
elsewhere, for cash, on credit or for future delivery, and upon such other
terms as the Lender may deem commercially reasonable. The Pledgor agrees that,
to the extent notice of sale shall be required by law, at least ten days'
notice to the Pledgor of the time and place of any public sale or the time
after which any private sale is to be made shall constitute reasonable
notification. The Lender shall not be obligated to make any sale of Pledged
Collateral regardless of notice of sale having been given. The Lender may
adjourn any public or private sale from time to time by announcement at the
time and place fixed therefor, and such sale may, without further notice, be
made at the time and place to which it was so adjourned.

(b)	Any cash held by the Lender as Pledged Collateral and all cash proceeds
received by the Lender in respect of any sale of, collection from, or other
realization upon all or any part of the Pledged Collateral may, in the
discretion of the Lender, be held by the Lender as collateral for, and/or then
or at any time thereafter be applied (after payment of any amounts payable to
the Lender pursuant to section 13) in whole or in part by the Lender against,
all or any part of the Secured Obligations in such order as the Lender shall
elect. Any surplus of such cash or cash proceeds held by the Lender and


<PAGE>
remaining after payment in full of all the Secured Obligations shall be paid
over to the Pledgor or to whomsoever may be lawfully entitled to receive such
surplus.

12.	Registration Rights. If the Lender shall determine to exercise its
right to sell all or any of the Pledged Collateral pursuant to section 11, the
Pledgor agrees that, upon request of the Lender, the Pledgor will, at its own
expense:

(a)	execute and deliver, and cause each issuer of the Pledged Collateral
contemplated to be sold and the directors and officers thereof to execute and
deliver, all such instruments and documents, and do or cause to be done all
such other acts and things, as may be necessary or, in the opinion of the
Lender, advisable to register such Pledged Collateral under the provisions of
the 1933 Act, and to cause the registration statement relating thereto to
become effective and to remain effective for such period as prospectuses are
required by law to be furnished, and to make all amendments and supplements
thereto and to the related prospectus which, in the opinion of the Lender, are
necessary or advisable, all in conformity with the requirements of the 1933 Act
and the rules and regulations of the SEC applicable thereto;

(b)	use its best efforts to qualify the Pledged Collateral under the state
securities or "Blue Sky" laws and to obtain all necessary governmental
approvals for the sale of the Pledged Collateral, as requested by the Lender;

(c)	cause each such issuer to make available to its security holders, as
soon as practicable, an earning statement which will satisfy the provisions of
section 11(a) of the 1933 Act; and

(d)     do or cause to be done all such other acts and things as may be
necessary to make such sale of the Pledged Collateral or any part thereof
valid and binding and in compliance with applicable law.

13.	Expenses. The Pledgor will upon demand pay to the Lender the amount of
any and all reasonable expenses, including the reasonable fees and expenses of
its counsel and of any experts and agents, which the Lender may incur in
connection with (i) the administration of this Agreement, (ii) the custody or
preservation of, or the sale of, collection from, or other realization upon,
any of the Pledged Collateral, (iii) the exercise or enforcement of any of the
rights of the Lender hereunder or (iv) the failure by the Pledgor to perform or
observe any of the provisions hereof.

14.	Amendments, etc. No amendment or waiver of any provision of this
Agreement, and no consent to any departure by the Pledgor herefrom, shall in
any event be effective unless the same shall be in writing and signed by the
Lender, and then such waiver or consent shall be effective only in the specific
instance and for the specific purpose for which given.

15.	Addresses for Notices. All notices and other communications provided
for hereunder shall be in writing (including telecopier, electronic e-mail,
telegraphic, telex or cable communication) and mailed, telecopied, e-mailed,
telegraphed, telexed, cabled or delivered to it, at its address specified in
the Credit Agreement, or, as to either party, at such other address as shall be
designated by such party in a written notice to the other party. All such
notices and other communications shall be effective when received.

16.	Pursuant to the terms hereof and execute and deliver to the Pledgor
such documents as the Pledgor shall reasonabl	Continuing Security Interest;
Assignments under Credit Agreement. This Agreement shall create a continuing
<PAGE>
security interest in the Pledged Collateral and shall (i) remain in full force
and effect until the later of (x) the payment in full of the Note and all other
amounts payable under this Agreement and (y) the expiration or termination of
the Commitment, (ii) be binding upon the Pledgor, its successors and assigns,
and (iii) inure to the benefit of, and be enforceable by, the Lender and its
successors, transferees and assigns. Without limiting the generality of the
foregoing clause (iii), the Lender may assign or otherwise transfer all or any
portion of its rights and obligations under the Credit Agreement (including,
without limitation, all or any portion of its Commitment, the Loans and the
Note) to any other person or entity, and such other person or entity shall
thereupon become vested with all the benefits in respect thereof granted to the
Lender herein or otherwise. Upon the later of the payment in full of the Note
and all other amounts payable under this Agreement and the expiration or
termination of the Commitment, the security interest granted hereby shall
terminate and all rights to the Pledged Collateral shall revert to the Pledgor.
Upon any such termination, the Lender will, at the Pledgor's expense, return to
the Pledgor such of the Pledged Collateral as shall not have been sold or
otherwise applied pury request to evidence such termination.

17.	Governing Law; UCC Terms. This Agreement shall be governed by, and
construed in accordance with, the laws of the State of New York. Unless
otherwise defined herein or in the Credit Agreement, terms defined in Article 9
of the Code are used herein as therein defined.

18.	Counterparts. This Agreement may be executed in any number of
counterparts, and by different parties on separate counterparts, each of which
shall be an original, but all of which together shall constitute one agreement.

IN WITNESS WHEREOF, the Pledgor and the Lender have caused this Agreement to be
duly executed and delivered as of the date first above written.
