ARTICLE II 

THE BONDS 

SECTION 201. RESTRICTION ON ISSUANCE OF BONDS. No Bonds may be authenticated
and issued under the provisions of this Indenture except in accordance with
this Article II. Except as provided in Section 205 and Section 214 hereof, the
total aggregate principal amount of Bonds that may be issued and authenticated
hereunder is expressly limited to $6,000,000. 

SECTION 202. LIMITED OBLIGATIONS. (A) The Bonds, together with the premium, if
any, and the interest thereon, shall be limited obligations of the Issuer
payable, with respect to the Issuer, solely from the Trust Revenues, which
Trust Revenues are hereby pledged and assigned for the equal and ratable
payment of all sums due under the Bonds, and shall be used for no other purpose
than to pay the principal of, premium, if any, on and interest on the Bonds
except as may be otherwise expressly provided herein. 

(B)	THE BONDS ARE NOT AND SHALL NOT BE A DEBT OF THE STATE OR OF THE TOWN
OF COLONIE, NEW YORK AND NEITHER THE STATE NOR THE TOWN OF COLONIE, NEW YORK
SHALL BE LIABLE THEREON. THE BONDS DO NOT GIVE RISE TO A PECUNIARY LIABILITY OR
CHARGE AGAINST THE GENERAL CREDIT OR TAXING POWERS OF THE STATE OR OF THE TOWN
OF COLONIE, NEW YORK. 


(C)	No recourse shall be had for the payment of the principal of or
premium, if any, on or the interest on any Bond or for any claim based thereon
or on this Indenture against any past, present or future member, officer,
employee or agent (other than the Company), as such, of the Issuer or of any
predecessor or successor corporation, either directly or through the Issuer or
otherwise, whether by virtue of any constitution, statute or rule of law, or by
the enforcement of any assessment or penalty, or otherwise. 

SECTION 203. EXECUTION. (A) The Bonds shall be executed on behalf of the Issuer
by the manual or facsimile signature of its Chairman or its Vice Chairman, and
the Issuer's corporate seal, or a reproduction thereof, shall be impressed,
imprinted or otherwise reproduced thereon and attested by the manual or
facsimile signature of its Secretary or its Assistant Secretary. All such
facsimile signatures shall have the same force and effect as if said officers
had manually signed the Bonds. The reproduction of the Issuer's corporate seal
on the Bonds shall have the same force and effect as if the Issuer's corporate
seal had been impressed on the Bonds. 

(B)	In case any Authorized Representative of the Issuer whose signature
shall appear on any Bond shall cease to be such Authorized Representative
before the delivery of such Bond or the issuance of a new Bond following a
transfer or exchange, such signature or such facsimile shall nevertheless be
valid and sufficient for all purposes, the same as if such Authorized
Representative had remained in office until delivery. 

SECTION 204. AUTHENTICATION. Only such Bonds as shall have endorsed thereon the
Certificate of Authentication substantially in the forms set forth in the forms
of Bond attached hereto as Exhibits A and B duly executed by the manual
signature of an authorized officer of the Trustee shall be entitled to any
right or benefit under this Indenture. No Bonds shall be valid or obligatory
for any purpose unless and until such Certificate of Authentication shall have
been duly executed by the Trustee; and such executed Certificate of
Authentication upon any such Bond shall be conclusive evidence that such Bond
has been authenticated and delivered under this Indenture. The Trustee's
Certificate of Authentication on any Bond shall be deemed to have been executed
by it if signed by an authorized officer of the Trustee, but it shall not be
necessary that the same person sign the Certificate of Authentication on all of
the Bonds. In the event of the appointment of a Tender Agent, other than the
Trustee such Tender Agent may act as Co- Authenticating Agent with respect to
the Tendered Bonds. 

SECTION 205. MUTILATED, LOST, STOLEN OR DESTROYED BONDS. (A) In the event any
Bond is mutilated, lost, stolen or destroyed, the Issuer may execute and the
Trustee may authenticate a new Bond, executed by the Issuer as provided in
Section 203 hereof, of like maturity, interest rate and denomination as the
Bond so mutilated, lost, stolen or destroyed. Any mutilated Bond shall first be
surrendered to the Trustee; and in the case of any lost, stolen or destroyed
Bond, there shall first be furnished to the Trustee evidence of such loss,
theft or destruction satisfactory to the Trustee, together with indemnity
satisfactory to the Trustee. The Issuer or the Trustee may charge the holder or
owner of such Bond a sum sufficient to cover any tax or other governmental
charge in connection with such exchange or substitution of such new Bond,
together with any other reasonable fees and expenses incurred by the Issuer or
the Trustee in connection therewith. 

(B)	Every Bond issued pursuant to the provisions of this Section 205 shall
be equally and proportionately entitled to the benefits of this Indenture with
all other Bonds secured by the Indenture. However, the Trustee shall not be


required to treat both the original Bond and any Bond issued in lieu thereof as
being Outstanding for purposes of determining the principal amount of Bonds
Outstanding under this Indenture or for the purpose of determining any
percentage of Bonds Outstanding hereunder, but both the original Bond and the
Bond issued in lieu thereof shall be treated as one and the same. 

(C)	Notwithstanding any other provision of this Section 205, in lieu of
delivering a new Bond for a Bond which has been mutilated, lost, stolen or
destroyed and which has matured, upon receipt of evidence of such mutilation,
loss, theft or destruction and indemnity satisfactory to the Trustee, the
Trustee may make payment for such Bond. 

SECTION 206. TRANSFER AND EXCHANGE OF BONDS; PERSONS TREATED AS OWNERS. (A) The
Trustee is designated and agrees to act as Bond Registrar and shall cause a
bond register to be kept on behalf of the Issuer at the Office of the Trustee
for the registration and transfer of Bonds. Except as provided in Section 213
hereof, any Bond, upon the surrender of such Bond to the Bond Registrar, may be
transferred, but only upon delivery of an assignment duly executed by the
registered owner or his duly authorized legal representative in the form
imprinted on the Bond or in such other form as shall be satisfactory to the
Bond Registrar. 

(B)	Except as otherwise provided in Section 206(E) or Section 213 hereof,
upon receipt of such Bond and upon satisfaction of the conditions set forth in
Section 206(A) and Section 206(C) hereof, the Trustee shall immediately record
the transfer of such bond on the bond register and cause the transferee or
transferees to be the registered owner of such Bond. Upon any such registration
of transfer, the Issuer shall execute and the Trustee shall authenticate and
deliver in exchange for such Bond one or more new Bonds, executed by the Issuer
as provided in Section 203 hereof, registered in the name of the designated
transferee thereof, of any denomination or denominations authorized by this
Indenture and for the same aggregate principal amount as the Bond or Bonds
surrendered for transfer. 

(C)	In the event of the appointment of a Tender Agent, other than the
Trustee, such Tender Agent may act as Co-Bond Registrar with respect to
Tendered Bonds. 

(D)	No service charge shall be made for any transfer or exchange of Bonds,
but in all cases in which Bonds shall be transferred or exchanged hereunder,
the Issuer or the Trustee may make a charge for every transfer or exchange of
Bonds sufficient to reimburse them for any tax, fee or other governmental
charge required to be paid with respect to such transfer or exchange, and such
charge shall be paid before any such new Bond shall be delivered. 

(E)	The Person in whose name any Bond shall be registered shall be deemed
and regarded as the absolute Owner thereof for all purposes, and payment of or
on account of the principal of, or the premium if any or interest on, any such
Bond shall be made only to or upon the order of the registered Holder thereof
or his duly authorized legal representative, subject to the terms of Section
207(C) hereof. Such registration may be changed only as provided in this
Section 206, and no other notice to the Issuer or the Trustee shall affect the
rights or obligations with respect to the transference of any Bond or be
effective to transfer any Bond. All payments to the Person in whose name any
Bond shall be registered shall be valid and effectual to satisfy and discharge
the liability upon such Bond to the extent of the sum or sums so paid. 



(F)	The Trustee shall not be required to make any such transfer or exchange
of (1) any Bond during the fifteen (15) days next preceding a Bond Payment Date
or (2) any Bond selected for redemption in whole or in part under Article III
hereof; provided, however, that in the event of a Bond selected for redemption
in part, nothing in this paragraph shall prohibit exchange of the remaining
portion of such Bond redeemed in part for a new Bond with a reduced principal
amount or the transfer or exchange of any such new Bond; provided, further that
the foregoing shall not apply to the registration or transfer of any Bond which
has been tendered to the Tender Agent pursuant to Section 304 hereof, and in
any such case, for purposes of selection for redemption, the Bond so tendered
and the Bond issued to the transferee thereof shall be deemed and treated as
the same Bond. 

SECTION 207. PAYMENT PROVISIONS. (A) Payment of the principal of, premium, if
any, on and interest on the Bonds shall be made in lawful money of the United
States of America. 

(B)	Interest and any Sinking Fund Payment or principal payment due prior to
maturity on any Bond which is payable, and which is punctually paid or duly
provided for, on any Bond Payment Date shall be paid to the Person appearing on
the bond register as the registered owner of that Bond (or one or more
Predecessor Bonds) at the close of business on the Regular Record Date, by
check or draft of the Trustee mailed by the Trustee on such Bond Payment Date
to such registered owner at his address as it appears on the bond register;
provided that at the option of any Holder of Bonds in an aggregate principal
amount of $250,000 or greater, the Trustee shall cause such amounts to be
transmitted on such Interest Payment Date by wire transfer at such owner's
written request to the bank account number on file with the Trustee, provided
such owner has delivered adequate instructions regarding same to the Trustee at
least ten (10) Business Days prior to such Bond Payment Date. 

(C)	Any interest and any Sinking Fund Payment or principal payment due
prior to maturity on any Bond which is payable, but is not punctually paid or
duly provided for, on any Bond Payment Date (herein called "Defaulted
Payments") shall forthwith cease to be payable to the Person appearing on the
bond register as the registered owner on the relevant Regular Record Date
solely by virtue of such Person having been such registered owner; and the
Trustee shall make payment of any Defaulted Payments on Bonds to the Persons in
whose names such Bonds (or their respective Predecessor Bonds) are registered
at the close of business on a Special Record Date for the payment of such
Defaulted Payments, which shall be fixed in the following manner. The Trustee
shall determine the amount of Defaulted Payments to be paid on each Bond and
establish the date of the proposed payment (which date shall be such as will
enable the Trustee to comply with the next sentence hereof), and money in the
aggregate amount of the proposed Defaulted Payments shall be segregated by the
Trustee to be held in trust for the benefit of the Persons entitled to such
Defaulted Payments as in this Subsection provided and not to be deemed part of
the Trust Revenues. Thereupon the Trustee shall fix a Special Record Date for
the payment of such Defaulted Payments which shall be not more than fifteen
(15) nor less than ten (10) days prior to the date of the proposed payment. The
Trustee shall promptly notify the Issuer, the Bank and the Company of such
Special Record Date and shall cause notice of the proposed payment of such
Defaulted Payments and the Special Record Date therefor to be mailed one time,
first-class postage prepaid, to each registered owner of a Bond at his address
as it appears in the bond register not less than ten (10) days prior to such
Special Record Date. Notice of the proposed payment of such Defaulted Payments
and the Special Record Date therefor having been mailed as aforesaid, such
Defaulted Payments shall be paid to the Persons in whose names the Bonds (or
their respective Predecessor Bonds) are registered on such Special Record Date.


(D)	Subject to the foregoing provisions of this Section, each Bond
delivered under this Indenture upon transfer of or in exchange for or in lieu
of any other Bond shall carry all the rights to interest and any Sinking Fund
Payments or principal payments due prior to maturity accrued and unpaid, and to
accrue, which were carried by such other Bond, and each such Bond shall bear
interest from such date so that neither gain nor loss in interest shall result
from such transfer, exchange or substitution. 

(E)	The principal of and premium, if any, on any Bonds due at maturity
shall be payable at the Office of the Trustee, upon presentation and surrender
of such Bond by the registered owner thereof or his duly authorized legal
representative at the maturity of such Bond or such other date as such payments
become due, by redemption or otherwise. Except as provided in subsection (B)
hereof, in the event of a partial redemption of any Bond, payment of the
redemption price shall be made to the registered owner or his duly authorized
legal representative only upon surrender to the Trustee of such Bond, and upon
such surrender the Trustee shall authenticate a new Bond executed by the Issuer
as provided in Section 203 for the unredeemed portion of such Bond.

premium, if any, or interest on any Bond from other than Non-Preference Moneys.

shall authenticate and deliver in lieu of definitive Bonds, temporary printed,
lithographed or typewritten Bonds, in any authorized denomination, in
substantially the tenor set forth in Exhibits A and B attached hereto and with
such appropriate omissions, insertions and variations as may be required. 

(B)	If the Bonds are no longer Book Entry Bonds and if temporary Bonds
shall have been issued, the Issuer shall, at the sole cost and expense of the
Company, cause the definitive Bonds to be prepared and to be executed and
delivered to the Trustee, and the Trustee, upon presentation to it at the
Office of the Trustee of any temporary Bond, shall cancel the same and
authenticate and deliver in exchange therefor, without charge to the owner
thereof, a definitive Bond or Bonds of an equal aggregate principal amount of
the same maturity and bearing interest at the same rate as the temporary Bond
surrendered. Until so exchanged, the temporary Bonds shall in all respects be
entitled to the same benefit and security of this Indenture as the definitive
Bonds to be issued and authenticated hereunder. 

SECTION 209. SPECIFIC DETAILS OF BONDS. (A) The Bonds shall be issued in the
aggregate principal amount of $6,000,000, shall be designated "Town of Colonie
Industrial Development Agency Taxable Industrial Development Revenue Bonds
(Mechanical Technology Incorporated Project - Letter of Credit Secured), Series
1998A". The Bonds shall be numbered from one upward and prefixed "R". The Bonds
shall be issued in the denomination of $100,000 or any integral multiple of
$5,000 in excess thereof. Interest on the Bonds prior to the Conversion Date
shall be payable on the first (1st) Thursday of each month, commencing January
7, 1999. 

(B)	(1)	The Bonds shall be dated the Closing Date and shall bear
interest from the Closing Date, or from the most recent Interest Payment Date
to which interest has been paid. The Bonds shall mature on December 1, 2013. 

(2)	The Bonds shall bear interest as follows: 




(a)	From the Closing Date through and including December 23, 1998, the
Bonds shall bear interest at a rate per annum equal to five and fifty-five
hundredths percent (5.55%). 

(b)	Thereafter, except as provided in (e) below, the Bonds (other than
Pledged Bonds) shall bear interest at the "Adjustable Rate". 

(i)	The Adjustable Rate shall be the rate of interest established by the
Remarketing Agent on the first Business Day prior to each Adjustment Date,
which in the Remarketing Agent's reasonable judgment would result, as nearly as
practicable, in the market value of the Bonds on an Adjustment Date being equal
to one hundred percent (100%) of the principal amount thereof. The Adjustable
Rate so determined shall be adjusted in accordance with the directions of the
Remarketing Agent on the Adjustment Date and shall remain in effect through and
including the day prior to the next following Adjustment Date. 

(ii)	In determining the Adjustable Rate pursuant to the foregoing Section
209(B)(2)(b)(i), the Remarketing Agent shall take into account, to the extent
applicable, (A) the market interest rates for comparable securities held by
open-end municipal or other fixed income bond funds or other institutional or
private investors with substantial portfolios (w) with interest rate adjustment
periods and demand purchase options substantially identical to the Bonds, (x)
bearing interest at a variable rate intended to maintain par value, (y) rated
by a national credit rating agency in the same category as the Bonds or, if not
rated, secured by substantially the same level of security as the Bonds, and
(z) the interest on which is included in gross income of the holders thereof
for federal income taxation purposes; (B) other financial market rates and
indices which may have a bearing on the Adjustable Rate (including, but not
limited to rates borne by commercial paper, Treasury bills, commercial bank
prime rates, certificate of deposit rates, federal funds rates, the London
Interbank Offered Rate, indices maintained by The Bond Buyer, and other
publicly available taxable interest rate indices); (C) general financial market
conditions (including current forward supply); (D) factors particular to the
Project or the credit standing of the Company and the Bank; and (E) such other
factors which the Remarketing Agent deems appropriate. 

(iii)	On the Business Day prior to each Adjustment Date, the Remarketing
Agent shall notify the Trustee, by Immediate Notice, of the Adjustable Rate. 

(c)	If for any reason the position of Remarketing Agent is vacant or the
Remarketing Agent fails to act, the Adjustable Rate shall be determined by a
third party selected by the Company at the Company expense and shall be equal
to one hundred percent (100%) of the yield applicable to 13-week United States
Treasury bills determined by such third party on the basis of the average per
annum discount rate at which such 13- week Treasury bills shall have been sold
(1) at the most recent Treasury auction conducted during the immediately
preceding Adjustment Period, (2) if no such auction shall have been conducted
during the immediately preceding Adjustment Period, at the most recent Treasury
auction conducted prior to such preceding Adjustment Period, plus fifty (50)
basis points; provided, however, that in the event the Company notifies the
Trustee that an index (as published in The Wall Street Journal) of seven-day
yield evaluations at par of issuers of securities, the interest on which is
includable in gross income for federal income tax purposes, and of comparable
rating to the rating on the Bonds, published by any nationally recognized
municipal securities evaluation service is available, the Adjustable Rate shall
be determined by the Trustee and shall be equal to such index. 




(d)	The Adjustable Rate shall be calculated based on a 365 or 366- day year
for the actual number of days elapsed. Further, each determination of the
Adjustable Rate pursuant to and in accordance with the foregoing terms of the
Indenture and the terms of the Bonds shall be conclusive and binding on the
Issuer, the Trustee, the Company, the Bank, and the holders of the Bonds. 

(e)	(i) From and after the Conversion Date through the maturity or earlier
redemption of the Bonds, the Bonds shall bear interest at the Fixed Rate, which
shall be a fixed rate (or rates) of interest established by the Remarketing
Agent at least fifteen (15), but not more than thirty (30) days prior to the
Conversion Date, which in the reasonable judgment of the Remarketing Agent
would result, as nearly as practicable, in the market value of the Bonds on the
Conversion Date being equal to one hundred percent (100%) of the principal
amount thereof. 

(ii)	(A)	At the Remarketing Agent's discretion, after the exercise of
the Conversion Option, the Bonds may be converted into serial bonds, with a
principal amount of Bonds maturing on a Principal Payment Date each year equal
to the principal amount required to be redeemed as set forth in Section 301(E)
hereof. In such event, each maturity of Bonds may bear a different interest
rate, each of which shall be determined by the Remarketing Agent in the same
manner as the Fixed Rate (for convenience each such rate shall be referred to
as the Fixed Rate); provided, however, that in no event shall the Remarketing
Agent be permitted to convert the Bonds into serial bonds as described above
without delivering to the Trustee an opinion of Bond Counsel that such
conversion is lawful under the Act and permitted under the Indenture. 

(B)	The Interest Payment Dates after the exercise of the Conversion Option
shall be semi-annual, with one Interest Payment Date being the first day of the
month preceding the Fixed Rate Conversion Date and the other Interest Payment
Date being the first day of the month six (6) months later. Principal shall be
payable annually thereafter in the amounts and the years set forth in Section
301(E) hereof on the Principal Payment Dates. 

(iii)	In determining the Fixed Rate, the Remarketing Agent shall take into
account, to the extent applicable, (A) market interest rates for comparable
securities which are held by open-end municipal or other fixed income bond
funds or other institutional or private investors with substantial portfolios
(w) with a term equal to the period to maturity remaining on the Bonds, (x) the
interest on which is includable in the gross income of the holders thereof for
federal income tax purposes, (y) rated by a national credit rating agency in
the same rating category as the Bonds, or, if not rated, secured by
substantially the same level of security as the Bonds, and (z) with redemption
provisions similar to those which have bearing on the Fixed Rate; (B) other
financial market rates and indices (including but not limited to rates borne by
taxable industrial development bonds, other taxable revenue bonds, Treasury
obligations, commercial bank prime rates, certificate of deposit rates, federal
funds rates, indices maintained by The Bond Buyer and other publicly available
taxable interest rates and indices); (C) general financial market conditions
(including current forward supply); (D) factors particular to the Project or
the credit standing of the Company and the Bank; and (E) such other factors
which the Remarketing Agent deems appropriate. 








(iv)	The Fixed Rate shall be calculated based on a 360-day year of twelve
30-day months. The determination of the Fixed Rate by the Remarketing Agent
pursuant to and in accordance with the terms of the Indenture and the terms of
the Bonds shall be conclusive and binding on the Issuer, the Trustee, the
Company, the Bank and the Holders of the Bonds. 

(v)	To exercise the Conversion Option, the Company shall deliver at least
sixty (60) days prior to the Conversion Date, written notice to the Trustee,
the Issuer and the Bank of its election of the Conversion Option. On the
Conversion Date, the Bonds shall be subject to a Mandatory Tender for purchase
as provided in Section 304 of the Indenture. Notwithstanding anything to the
contrary contained herein, such notice shall not be effective unless the Bank
shall have consented thereto in writing and such notice is accompanied by: 

(A)	a Substitute Letter of Credit with an expiration date of not earlier
than fifteen (15) days following the Principal Payment Date which is at least
three (3) years after the next succeeding Principal Payment Date and in an
amount equal to the sum of the aggregate principal amount of the Bonds then
Outstanding, 210 days' interest thereon computed at the Fixed Rate, together
with the Optional Redemption Premium; provided, however, that if the Letter of
Credit then in place has an expiration date of not earlier than fifteen (15)
days following the Principal Payment Date which is at least three (3) years
after the next succeeding Principal Payment Date and in an amount equal to the
aggregate principal amount of the Bonds then Outstanding, 210 days' interest
thereon computed at the Fixed Rate, together with the Optional Premium, no
Substitute Letter of Credit need be obtained; 

(B)	a statement as to whether the Bonds shall be serial bonds as set forth
in Section 209(B)(2)(e)(ii) above; and 

(C)	an opinion of Bond Counsel reasonably satisfactory to the Trustee, the
Issuer and the Bank to the effect that the exercise of the Conversion Option is
lawful under the Act and permitted by the Indenture. 

(f)	Notwithstanding anything herein to the contrary, any Pledged Bond shall
bear interest at a rate equal to the Bank Rate, as such rate shall change from
time to time; provided, however, that at no time shall the interest rate in
effect for any Pledged Bond exceed the maximum rate permitted by applicable
usury laws. 

(g)	Notwithstanding anything herein to the contrary, in no event will the
rate of interest borne by any Bond (except any Bond constituting a Pledged
Bond) exceed fifteen percent (15%) per annum. 

(h)	The Issuer hereby appoints the Company to act as agent of the Issuer
for purposes of exercising the Conversion Option, all as set forth in this
Indenture, and subject to compliance with the terms and provisions of this
Indenture. 

SECTION 210. DELIVERY OF THE BONDS. Upon the execution and delivery of this
Indenture, the Issuer shall execute and deliver the Bonds (including a number
of additional Bonds to be retained by the Trustee for authentication and
delivery upon transfer or exchange of any Bond) to the Trustee, and the Trustee
shall authenticate and deliver the Bonds to the purchasers thereof against
payment of the purchase price therefor, plus accrued interest to the day
preceding the date of delivery, upon receipt by the Trustee of the following: 

(A)	a certified copy of the Resolution; 


(B)	the executed original Letter of Credit; 

(C)	executed counterparts of the Indenture and the other Financing
Documents; 

(D)	a request and authorization to the Trustee on behalf of the Issuer
signed by an Authorized Representative of the Issuer to deliver the Bonds to
the purchasers thereof upon payment to the Trustee for the account of the
Issuer of the purchase price therefor; 

(E)	signed copies of the opinions of counsel to the Issuer, the Company and
the Bank, and of Bond Counsel, as required by the Bond Purchase Agreement; 

(F)	the certificates and policies, if available, of the insurance required
by the Installment Sale Agreement; 

(G)	a current survey of the Land certified to the Issuer and the Trustee; 

(H)	proof of compliance with the State Environmental Quality Review Act; 

(I)	evidence that the Project Facility is not an area of special flood
hazards, or a certificate and a policy, if available, of the insurance required
by Section 6.3(D) of the Installment Sale Agreement; and 

(J)	such other documents as the Trustee, the Bank or Bond Counsel may
reasonably require. 

SECTION 211. CANCELLATION OF BONDS. All Bonds surrendered to the Trustee for
payment, redemption, transfer or exchange shall be promptly cancelled by the
Trustee. No Bond shall be authenticated in lieu of or in exchange for any Bond
cancelled as provided in this Section 211, except as expressly provided by this
Indenture. All Bonds cancelled by the Trustee shall be destroyed by the Trustee
and shall not be reissued. At the request of the Company, certificates of
destruction evidencing such destruction shall be furnished by the Trustee to
the Issuer and the Company. 

SECTION 212. PAYMENTS DUE ON SATURDAYS, SUNDAYS AND HOLIDAYS. In any case where
the date of maturity of interest or a Sinking Fund Payment on or the principal
of any Bond or the date fixed for redemption of any Bond shall not be a
Business Day, then payment of interest on or principal or Redemption Price of
such Bond shall be made on the next succeeding Business Day with the same force
and effect as if made on the date of maturity or the date fixed for redemption,
and no interest shall accrue for the period after such date. 

SECTION 213. BOOK ENTRY BONDS. (A) Notwithstanding any other provision of this
Indenture, the Bonds are hereby authorized to be issued in book entry form as
Book Entry Bonds, with respect to which the following procedures shall apply. 

(B)	For all purposes of this Indenture, the Depository shall be deemed to
be holder of a Book Entry Bond and neither the Issuer, nor the Trustee shall
have any responsibility or obligation to the beneficial owner of such Bond or
to any direct or indirect participant in such Depository. Without limiting the
generality of the foregoing, neither the Issuer nor the Trustee shall have any
responsibility or obligation to any such participant or to the beneficial owner
of a Book Entry Bond with respect to (1) the accuracy of the records of the
Depository or any participant with respect to any beneficial ownership interest
in such Book Entry Bond, (2) the delivery to any participant of the Depository,
the beneficial owner of such Book Entry Bond or any other person, other than


the Depository, of any notice with respect to such Book Entry Bond, including
any notice of the redemption thereof, (3) the payment to any participant of the
Depository, the beneficial owner of such obligation or any other person, other
than the Depository, of any amount with respect to the principal or Redemption
Price of, or interest or Sinking Fund Payments on, such Book Entry Bond or (4)
any consent given or any other action taken by the Depository as Holder of the
Book Entry Bonds. 

(C)	The Issuer and the Trustee may treat the Depository of a Book Entry
Bond as the absolute owner of such Book Entry Bond for purpose of (1) payment
of the principal of, premium, if any, and interest on such Book Entry Bond, (2)
giving notices of redemption and of other matters with respect to such Book
Entry Bond, (3) registering transfers with respect to such Book Entry Bond, and
(4) for all other purposes whatsoever. The Trustee shall pay all principal of,
premium, if any, and interest and Sinking Fund Payments on, such Book Entry
Bond only to or upon the order of the Depository, and all such payments shall
be valid and effective to fully satisfy and discharge the Book Entry Bonds with
respect to such principal of, premium, if any, Sinking Fund Payments and
interest to the extent of the sum or sums so paid. No person other than the
Depository shall receive a Book Entry Bond or other instrument evidencing the
Issuer's obligation to make payments of the principal of, premium, if any,
Sinking Fund Payments and interest thereon. 

(D)	The Issuer, in its sole discretion, upon thirty (30) days prior written
notice to the Trustee and without the consent of the Trustee or the beneficial
owner of a Book Entry Bond or any other person, may terminate the services of
the Depository with respect to a Book Entry Bond if the Issuer determines that
(1) the Depository is unable to discharge its responsibilities with respect to
such Book Entry Bond or (2) a continuation of the requirement that all of the
Outstanding Bonds issued in book entry form be registered in the registration
books of the Issuer in the name of the Depository, is not in the best interest
of the beneficial owners of such Bonds, and the Issuer shall terminate the
services of the Depository upon receipt by the Issuer and the Trustee of
written notice from the Depository that it has received written requests that
such Depository be removed from its participants having beneficial interests,
as shown in the records of the Depository, in an aggregate amount of not less
than fifty percent in principal amount of the then Outstanding Book Entry
Bonds. 

(E)	Upon the termination of the services of a Depository with respect to a
Book Entry Bond, or upon the resignation of a Depository with respect to a Book
Entry Bond, after which no substitute securities depository willing to
undertake the functions of such Depository can be found which, in the opinion
of the Issuer, is able to undertake such functions upon reasonable and
customary terms, such Bonds shall no longer be registered in the registration
books kept by the Trustee in the name of a Depository, but may be registered in
the name of the beneficial owners of such Bonds, and such beneficial owners,
upon registration of such Bonds in their names, shall become the holders of
such Bonds. 

(F)	Notwithstanding any other provisions of the Indenture, the Trustee
shall have no liability for any inconsistency, if any, between a letter of
representations that may be executed and delivered by the Issuer and/or the
Trustee with the Depository and the provisions hereof, and with respect to any
such inconsistency, the provisions of such letter of representations shall
control. 




SECTION 214. ADDITIONAL BONDS. (A) So long as the Installment Sale Agreement is
in effect and no Event of Default exists thereunder or hereunder (and no event
exists which upon notice or lapse of time or both, would become an Event of
Default thereunder), the Issuer may, upon request from the Company, issue one
or more series of Additional Bonds to provide funds to pay any one or more of
the following: (1) costs of completion of the Project Facility in excess of the
amount in the Project Fund; (2) costs of refunding or advance refunding any or
all of the Bonds previously issued; (3) costs of making any modifications,
additions or improvements to the Project Facility; or (4) costs of the issuance
and sale of the Additional Bonds, capitalized interest, funding debt service
reserves, and other costs reasonably related to any of the foregoing.
Additional Bonds may mature at different times, bear interest at different
rates and otherwise vary from the Bonds as authorized under Article II of the
Indenture, all as may be provided in the supplemental Indenture authorizing the
issuance of such Additional Bonds.

Credit issued by a Substitute Bank in the aggregate principal amount of all

Bank enforceable against the Bank in accordance with its terms, subject to the
standard exceptions with respect to bankruptcy laws, equitable remedies and
specific performance; 

(3)	evidence that the Financing Documents, as amended or supplemented in
connection with the issuance of the Additional Bonds, provide that (a) the
Bonds referred to therein shall mean and include the Additional Bonds being
issued as well as the Bonds originally issued under the Indenture and any
Additional Bonds theretofore issued, and (b) the Project Facility referred to
in the Financing Documents includes any Additional Facilities being financed;

(5)	a written opinion of counsel to the Company which shall state that the
execution and delivery of the amendments to the Financing Documents by the

binding special obligations of the Issuer, subject to the standard exceptions
with respect to bankruptcy laws, equitable remedies and specific performance;
and that the issuance of the Additional Bonds will not, in and of itself,
adversely affect the validity of the Bonds originally issued under the
Indenture or any Additional Bonds theretofore issued; 

(9)	written evidence from each rating agency, if any, by which the Bonds

Indenture, without preference, priority or distinction of any Bond over any
other. 

(D)	The consent of the Bondholders shall not be required prior to the

amendments to the Financing Documents required in connection therewith. The
Trustee shall, however, notify in writing the Bondholders and each rating


agency of the issuance of the Additional Bonds, detailing, at least, the
aggregate principal amount of such Bonds, and summarizing the nature of the
amendments to the Financing Documents proposed to be executed in connection

ARTICLE III 

REDEMPTION OF BONDS PRIOR TO MATURITY 

SECTION 301. REDEMPTION OF BONDS PRIOR TO MATURITY. (A) The Bonds are subject
to redemption prior to maturity (1) as a whole, without premium, as provided in
Section 406 hereof, in the event of (a) a taking in Condemnation of, or failure
of title to, all or substantially all of the Project Facility, (b) damage to or
destruction of part or all of the Project Facility and election by the Company
to redeem the Bonds in accordance with Section 7.1 of the Installment Sale
Agreement, or (c) a taking in Condemnation of part of the Project Facility and
election by the Company to redeem the Bonds in accordance with Section 7.2 of
the Installment Sale Agreement, or (2) in part, without premium, (a) as
provided in Section 406(G) hereof, in the event that (i) to the extent excess
moneys remain in the Insurance and Condemnation Fund following damage or
condemnation of a portion of the Project Facility and completion of the repair,
rebuilding or restoration of the Project Facility by the Company, and (ii) such
moneys are not paid to the Company pursuant to Section 406(G) hereof, or (b) as
provided in Section 403 hereof, in the event that excess moneys remain in the
Project Fund after the Completion Date. In any such event, the Bonds shall be
redeemed, as a whole or in part, as the case may be, in the manner provided in
this Article III, at such time as the Trustee determines, at a redemption price
equal to the principal amount thereof, plus accrued interest to the redemption
date, without premium. 

(B)	The Bonds are also subject to redemption prior to maturity in the event
of failure by the Company to provide a Substitute Letter of Credit at least
forty-five (45) days prior to the Interest Payment Date immediately preceding
the expiration date of the Letter of Credit then in effect. In any such event,
the Bonds shall be redeemed, as a whole, on such Interest Payment Date at a
redemption price equal to the principal amount to be redeemed, plus accrued
interest to the redemption date, without premium. 

(C)	The Bonds are also subject to redemption prior to maturity upon receipt
by the Trustee of a written notice from the Bank of the occurrence and
continuance of a default by the Company under the Reimbursement Agreement and
the Bank's election to compel redemption of the Bonds. In either such event,
the Bonds shall be redeemed, as a whole, in the manner provided in this Article
III, on the earliest date for which the Trustee can give notice of redemption
pursuant to Section 303 hereof, at a redemption price equal to the principal
amount thereof, plus accrued interest to the redemption date, without premium. 

(D)	(1) On or prior to the Conversion Date, the Bonds are also subject to
redemption prior to maturity in denominations of $5,000 or any integral
multiple of $5,000 in excess thereof at the option of the Company by exercise
of its right to prepay the installment purchase payments payable under the
Installment Sale Agreement as provided in Section 5.5 of the Installment Sale
Agreement, on any Interest Payment Date, in the manner provided in this Article
III, at a redemption price equal to the principal amount thereof, plus accrued
interest to the redemption date, without premium. 





(2)	After the Conversion Date, the Bonds are subject to redemption, at the
option of the Company by exercise of its right to prepay the installment
purchase payments under the Installment Sale Agreement as provided in Section
5.5 thereof, as a whole or in part on any Interest Payment Date occurring after
the end of the applicable call protection period at the redemption prices,
expressed as percentages of unpaid principal amount to be redeemed, plus
accrued interest to the redemption date, determined as follows: the call
protection period and redemption prices shall be determined by the Remarketing
Agent, after taking into account the factors described in Section 209(B)(2)(e)
hereof and such other factors which the Remarketing Agent deems appropriate.
The determination of the call protection period and redemption prices by the
Remarketing Agent pursuant to and in accordance with the terms of the Indenture
shall be conclusive and binding on the Issuer, the Trustee, the Company, the
Bank and the Holders of the Bonds. 

(E) The Bonds will also be subject to scheduled mandatory redemption, by lot in
such manner as the Trustee shall deem fair and appropriate for random
selection, prior to maturity, commencing December 1, 1999 and on each December
1 thereafter, by the application of Sinking Fund Payments at a redemption price
equal to one hundred percent (100%) the principal amount thereof, plus accrued
interest to the redemption date, without premium, on December 1 of the years
and in the principal amounts set forth below: 

YEAR	SINKING FUND PAYMENT            YEAR	SINKING FUND PAYMENT 
1999	$285,000			2006	$385,000
2000	$275,000			2007    $410,000
2001	$290,000			2008	$435,000
2002	$310,000			2009    $460,000
2003	$325,000			2010	$485,000
2004	$345,000			2011    $515,000
2005	$365,000			2012	$540,000 





























Following retirement by mandatory sinking fund redemption prior to their Stated
Maturity, there will remain $575,000 principal amount of the Bonds maturing on
December 1, 2013 to be paid at maturity. 

(F)	In no event shall the Trustee, in connection with any redemption of
Bonds under this Section 301, pay any portion of the principal of, premium, if
any, or interest on any Bond from other than Non-Preference Moneys.
Furthermore, the Trustee shall make such payments by first drawing on the
Letter of Credit pursuant to Section 408 hereof. 

(G)	In the event of any partial redemption, the particular Bonds or
portions thereof to be redeemed shall be selected by the Trustee not more than
sixty (60) days prior to the redemption date by lot. The Trustee shall apply
any partial redemption payments (other than a scheduled mandatory redemption)
to the schedule of mandatory redemption in inverse order of maturity. After the
Conversion Date, if the Bonds are serial bonds as provided in Section
209(B)(2)(e)(ii) hereof, the Bonds shall be redeemed in inverse order of
maturity selected by lot. Further, the Trustee may provide for the selection
for redemption of portions (equal to $5,000 or any whole multiple thereof) of
Bonds of a denomination larger than $5,000. In no event shall the principal
amount of Bonds subject to any partial redemption be other than a whole
multiple of $5,000; provided, however, that no $5,000 portion of a Bond shall
be redeemed if it results in the unredeemed portion of the Bond being less than
$100,000. 

SECTION 302. COMPANY'S ELECTION TO REDEEM. (A) The Company shall give written
notice to the Trustee, the Bank and the Issuer of its election to cause
redemption of Bonds prior to maturity pursuant to subsections (A) and (D) of
Section 301 hereof and of the redemption date. 

(B)	In the event of an election by the Company to redeem the Bonds pursuant
to Section 301(D) hereof, such notice shall be given at the time the Company
delivers to the Trustee either (1) the prepayment of installment purchase
payments with which the Bonds are to be redeemed, or (2) the assurance from the
Bank that the Letter of Credit may be drawn upon to pay the redemption price of
the Bonds, described in Section 5.5 of the Installment Sale Agreement, and the
redemption date specified in such notice shall be deemed to be (notwithstanding
the actual date set forth therein) the first Interest Payment Date more than
thirty (30) days after such payment or assurance, as the case may be, is
received by the Trustee and on which any moneys delivered to the Trustee by the
Company for such purpose shall be Non-Preference Moneys. 

SECTION 303. NOTICE OF REDEMPTION; PAYMENT OF REDEEMED BONDS. (A) Notice of the
intended redemption of each Bond subject to redemption shall be given by the
Trustee one time by first class mail postage prepaid to the registered Owner of
such Bond at the address of such Owner shown on the Trustee's bond register and
to the Bank at its address set forth of in Section 1103 hereof. All such
redemption notices shall be given not less than thirty (30) days prior nor more
than forty-five (45) days prior to the date fixed for redemption. A follow-up
notice shall be given by the Trustee by registered or certified mail to each
registered owner who has not submitted a Bond subject to redemption within
ninety (90) to one hundred twenty (120) days following the redemption date.
Each notice shall specify the redemption price, the principal amount of the
Bonds to be redeemed, the numbers of the Bonds to be redeemed if less than all
of the Bonds are to be redeemed, the redemption date and the place or places
where amounts due upon such redemption will be payable. Such notice shall
further state that payment of the applicable redemption price plus accrued
interest to the redemption date will be made upon presentation and surrender of


the Bonds or portions thereof to be redeemed; that upon presentation and
surrender to the Trustee of any Bond being redeemed in part, a new Bond in the
principal amount of the unredeemed portion of such Bond will be issued; and
that the Bonds or portions thereof so called for redemption will be deemed
redeemed and will cease to bear interest on the specified redemption date,
provided Non-Preference Moneys for their redemption have been duly deposited in
the Bond Fund and, except for the purpose of payment, that such Bonds will no
longer be protected by this Indenture. The failure to give any such notice, or
any defect therein, shall not affect the validity of any proceeding for the
redemption of any Bond with respect to which no such failure to give notice, or
defect therein, has occurred. Notwithstanding anything herein to the contrary,
the Trustee shall not give any notice under this Section 303 in the case of an
optional redemption pursuant to Section 301(D) hereof requiring the payment of
a premium upon such redemption unless the Company shall have complied with the
provisions of Section 302(B) hereof. 

(B)	After notice shall have been given in the manner provided in Subsection
(A) above, the Bonds or portions thereof called for redemption shall become due
and payable on the redemption date so designated. Upon presentation and
surrender of such Bonds at the Office of the Trustee, such Bonds shall be paid
at the Redemption Price, plus accrued interest to the redemption date. If there
shall be selected for redemption less than all of a Bond, the Issuer shall,
upon the surrender of such Bond and with no charge to the Owner thereof, (1)
pay the Redemption Price of the principal amount called for redemption, and (2)
cause the Trustee to authenticate and deliver for the unredeemed balance of the
principal amount of such Bond so surrendered a fully registered Bond of like
maturity in any of the authorized denominations. 

(C)	If, on the redemption date, moneys for the redemption of all Bonds or
portions thereof to be redeemed, in an amount equal to the principal of such
Bonds or portions thereof to be redeemed, together with any premium due thereon
and interest thereon to the redemption date, shall be held by the Trustee so as
to be available therefor on such date, the Bonds or portions thereof so called
for redemption shall cease to bear interest, and such Bonds or portions thereof
shall no longer be Outstanding hereunder or be secured by or be entitled to the
benefits of this Indenture. If such moneys shall not be so available on the
redemption date, such Bonds or portions thereof shall continue to bear interest
until paid at the same rate as they would have borne had they not been called
for redemption and shall continue to be secured by and be entitled to the
benefits of this Indenture. 

SECTION 304. MANDATORY TENDER; NOTICE. (A) The Bonds are subject to Mandatory
Tender upon the exercise by the Company of the Conversion Option or the
delivery by the Company of an Alternate Letter of Credit. 

(B)	Upon the exercise by the Company of the Conversion Option with respect
to the Bonds, all such Bonds which have not been called for redemption shall be
subject to Mandatory Tender by the owner thereof on the Conversion Date.
Notwithstanding the foregoing, each Bondholder may, by delivery to the Trustee
for receipt at least by twenty (20) days immediately preceding the Conversion
Date of an irrevocable election not to tender, elect to continue to hold its
Bonds (or portions thereof) past the Conversion Date at a Fixed Rate to be in

hereof shall be required to deliver their Bonds to the Trustee for purchase at
the Purchase Price on the Conversion Date or the Alternative Security Date, as

the Undelivered Bonds, shall be deemed to have been purchased pursuant to this

maturity or at the date fixed for redemption or otherwise, or (2) the date on
which such moneys would escheat to the State, such amounts shall be paid by the
Trustee first to the Bank to the extent any amounts remain unpaid by the
Company under the Reimbursement Agreement, with any balance to be paid to the
Company. Thereafter, Bondholders shall be entitled to look only to the Company
and/or the Bank, as the case may be, for payment, and then only to the extent
of the amount so repaid to the respective parties, who shall not be liable for
any interest thereon and shall not be regarded as trustees of such money. The
Trustee shall, at least sixty (60) days prior to the expiration of the above
described period, give notice to any Owner who has not presented any Bond for
payment that any moneys held for the payment of any such Bond will be returned
as provided in this Section 409 at the expiration of such period. The failure
of the Trustee to give any such notice shall not affect the validity of any
transfer of funds pursuant to this Section 409. 

SECTION 410. INVESTMENT OF FUNDS. Any moneys held as part of any fund created
herein shall be continuously invested and reinvested, from time to time, by the
Trustee in Authorized Investments at the written or oral direction of the
Company, but, if oral, to be promptly confirmed in writing by the Company, or,
in the absence of such direction, in Authorized Investments with the shortest
available maturities. The Company shall direct that any moneys held in any fund
shall be invested so that (1) all investments shall mature or be subject to
mandatory redemption by the holder of such investments (at not less than the
principal amount thereof, or the cost of acquisition, whichever is lower), and
all deposits in time accounts shall be subject to withdrawal, without penalty,
not later than the date when the amounts will foreseeably be needed for
purposes of the Indenture, (2) investments of moneys on deposit in the Bond


Fund shall mature or be subject to mandatory redemption by the holder (at not
less than the principal amount thereof) not more than ninety (90) days from the
date of acquisition, and in no event shall moneys on deposit in the Bond Fund
be invested in investments described in clause (J) of the definition of
Authorized Investments and (3) moneys received pursuant to a draw on the Letter
of Credit and moneys in the Bond Fund Non-Preference Moneys Subaccount shall
only be invested in cash or investments described in clause (A) of the
definition of Authorized Investments which mature in not more than 30 days or
as needed; provided, however, in the event moneys on deposit in the Bond Fund
Non-Preference Moneys Subaccount are invested in investments described in
clause (A) of the definition of Authorized Investments, such investments shall
be non-callable. The investments so purchased shall be held by the Trustee and
shall be deemed at all times to be a part of the fund in which such moneys were
held. The Trustee is directed to sell and reduce to cash a sufficient amount of
such investments whenever the cash balance in said fund shall be insufficient
to cover a proper disbursement from said fund. The Trustee may make any
investment permitted by this Section 410 through its own investment department.
The Trustee shall not be liable (except for gross negligence or willful
misconduct) for any depreciation in the value of any investment made pursuant
to this Section 410 or for any loss arising from such investment. 

SECTION 411. FINAL DISPOSITION OF MONEYS. In the event there are no Bonds
Outstanding, and subject to any applicable law to the contrary, after payment
of all fees, charges and expenses, including, but not limited to reasonable
attorney's fees, of the Issuer, the Trustee, the Company and the Bank and all
other amounts required to be paid hereunder and under the other Financing
Documents, all amounts remaining in any fund established under the Indenture
shall be transferred to the Company (except amounts held with respect to the
Unassigned Rights, which amounts shall be paid to the Issuer); provided,
however, that, in the event that the Bonds are retired or redeemed, in whole or
in part, from amounts drawn on the Letter of Credit and the Bank remains
unreimbursed for such amounts, such remaining amounts shall be transferred to
the Bank to be applied against the obligation of the Company to repay the Bank
for amounts paid under the Letter of Credit or any other Financing Document,
and any amounts in excess thereof shall be paid to the Company. 

SECTION 412. PERIODIC REPORTS BY TRUSTEE. Within fifteen (15) days after each
January 1 and July 1, the Trustee shall furnish to the Issuer, the Company and
the Bank, commencing on or before the fifteenth day of the first such date
following the date in which the Bonds are delivered, a report on the status of
each of the funds established under this Article IV, showing at least the
balance in such fund as of the final day of the period with respect to which
the last such report described (or, if such report is to first such report, as
of the Closing Date), the total of deposits into (including interest on
investments) and the total of disbursements from such fund, the dates of such
deposits and disbursements, and the balance in such fund on the last day of the
period to which such report relates (which date shall be not earlier than the

proceedings to be taken in connection with the enforcement of the terms and
conditions of the Indenture, the Letter of Credit, the Installment Sale
Agreement or the other Financing Documents, or for the appointment of a

have been declared due and payable, all such moneys shall be applied: 

FIRST - to the payment to the Persons entitled thereto of all installments of
interest then due on the Bonds, in the order of the maturity of the
installments of such interest and, if the amount available shall not be
sufficient to pay in full any particular installment, then to the payment
ratably, according to the amounts due on such installment, to the Persons
entitled thereto, without any discrimination or privilege;

right to file proof of claims, under the Indenture or under any of the Bonds
may be enforced by the Trustee without the possession of any of the Bonds or
the production thereof in any trial or other proceedings relating thereto, and
any such suit or proceeding instituted by the Trustee shall be brought in its
name as Trustee without the necessity of joining as plaintiffs or defendants
any holders of the Bonds. Subject to the provisions of Section 609 hereof and
any recovery or judgment shall be for the equal benefit of the holders of the
Outstanding Bonds. 

SECTION 611. RIGHTS AND REMEDIES OF BONDHOLDERS. No holder of any Bond shall
have any right to institute any suit, action or proceeding in equity or at law

receiver or any other remedy hereunder, unless an Event of Default under
Section 601(A) through (H) hereof has occurred or a default under Section
601(I) hereof has occurred of which the Trustee has been notified as provided

shall have offered reasonable opportunity either to proceed to exercise the
powers hereinbefore granted or to institute such action, suit or proceeding in
its own name; nor unless also they have offered to the Trustee indemnity as
provided in Section 701(I) hereof; nor unless the Trustee shall thereafter fail
or refuse to exercise the powers hereinbefore granted, or to institute such
action, suit or proceeding; and such notification, request and offer of
indemnity are hereby declared in every case at the option of the Trustee to be


conditions precedent to the execution of the powers and trusts of the
Indenture, and to any action or cause of action for the enforcement of the
Indenture, or for the appointment to the extent permitted by law of a receiver
or for any other remedy hereunder; it being understood and intended that no one
or more holders of the Bonds shall have any right in any manner whatsoever to
affect, disturb, or prejudice the Lien of the Indenture by any action or to
enforce any right hereunder except in the manner herein provided, and that all
proceedings at law or in equity shall be instituted, had and maintained in the
manner herein provided and for the equal benefit of the holders of all Bonds
then Outstanding. Nothing in the Indenture shall, however, affect or impair the
right of any Bondholder to enforce the payment of the principal of and interest
on any Bond at and after the maturity thereof, or the obligation of the Issuer
to pay the principal of and interest on each of the Bonds issued hereunder to
the respective holders thereof, at the time and place and from the source and
in the manner in the Bonds expressed. 

SECTION 612. TERMINATION OF PROCEEDINGS. In case the Trustee shall have
undertaken any proceedings to enforce any right under the Indenture and such
proceedings shall have been discontinued or abandoned for any reason, or shall
have been determined adversely, then and in every such case, the Issuer, the
Company, the Bank and the Trustee shall be restored to their former positions
and rights hereunder, and all rights, remedies and powers of the Trustee shall
continue as if no such proceedings had been taken. 

SECTION 613. WAIVERS OF EVENTS OF DEFAULT. The Trustee, with the prior written
consent of the Bank, shall waive any Event of Default hereunder and its
consequences and rescind any declaration of maturity of principal of and
interest on the Bonds upon the written request of the holders of a majority of
the aggregate principal amount of all the Bonds then Outstanding; provided,
however, that there shall not be waived (A) any default in the payment of the
principal of any Outstanding Bond at the date of maturity specified therein, or
upon proceedings for mandatory redemption, (B) any Event of Default requiring a
draw under the Letter of Credit unless the Trustee shall have received written
notice from the Bank that the Letter of Credit has been reinstated to its full
stated amount, if there has been a reduction thereon, or (C) any default in the
payment when due of the interest or premium on any such Bonds, unless prior to
such waiver or rescission all arrears of interest, with interest (to the extent
permitted by law) at the rate borne by the Bonds in respect of which such
default shall have occurred on overdue installments of interest or all arrears
of payments of principal when due (whether at the stated maturity thereof or
upon proceedings for redemption) as the case may be, shall have been paid or
provided for, and no such waiver or rescission shall extend to any subsequent
or other default, or impair any right consequent thereto. The Trustee shall not
grant any waiver or rescission hereunder unless all ordinary and extraordinary
fees and expenses of the Trustee, including, but not limited to, reasonable
attorneys' fees, incurred in connection with said default have been paid or
provided for, and in case of any such waiver or rescission, or in case any
proceeding taken by the Trustee on account of any such default shall have been
discontinued or abandoned or determined adversely, then, and in every such
case, the Issuer, the Trustee, the Bank and the Bondholders, respectively,
shall be restored to their former positions and rights hereunder. 

SECTION 614. NOTICE OF DEFAULTS; OPPORTUNITY TO CURE. (A) Anything herein to
the contrary notwithstanding, no default under Section 601(I) hereof shall
constitute an Event of Default until the Trustee shall have received written
notice thereof or shall have actual notice thereof and until actual notice of
such default by registered or certified mail shall be given by the Trustee or
by the holders of not less than twenty-five (25%) percent of the aggregate


principal amount of Bonds then Outstanding to the Issuer, the Bank and the
Company, and the Issuer, the Bank and the Company shall have had thirty (30)
days after receipt of such notice to correct said default or cause said default
to be corrected, and shall not have corrected said default or caused said
default to be corrected within the applicable period; provided, however, if
said default be such that it cannot be corrected within the applicable period,
it shall not constitute an Event of Default if corrective action is instituted
by the Issuer, the Bank or the Company within the applicable period and
diligently pursued until the default is corrected. 

(B)	The Trustee shall immediately notify the Issuer, the Company and the
Bank of any Event of Default known to the Trustee. 

SECTION 615. STATEMENT OF INCOME AND EXPENDITURES. Upon the occurrence and
continuance of an Event of Default, the Trustee shall render annually to the
Bondholders a summarized statement of income and expenditures in connection
with the Project Facility, but only to the extent, if any, that the Trustee can
obtain such information without unreasonable effort or expense. 

ARTICLE VII 

THE TRUSTEE 

SECTION 701. ACCEPTANCE OF TRUSTS. The Trustee hereby accepts the trusts
imposed upon it by the Indenture and agrees to perform said trusts upon the
following terms and conditions: 

(A)	The Trustee may execute any of the trusts or powers hereof and perform
any of its duties hereunder by or through attorneys, agents, receivers or
employees, but shall not be answerable for the conduct of the same if appointed
with due care, and shall be entitled to advice of counsel concerning all
matters of the trusts hereof and the duties hereunder, and may in all cases pay
such reasonable compensation to all such attorneys, agents, receivers and
employees as may be reasonably employed in connection with the trusts hereof.
The Trustee may act upon the opinion or advice of any attorney, who may be the
attorney or attorneys for the Issuer, and shall not be responsible for any loss
or damage resulting from any action or nonaction in reliance upon any such
opinion or advice. 

(B)	Except as expressly provided herein, the Trustee shall not be
responsible for any recital herein or in the Bonds (except in respect to the
authentication certificate of the Trustee endorsed on the Bonds), or for the
validity of the execution by the Issuer of the Indenture or of any supplements
thereto or instruments of further assurance, or for the sufficiency of the
security for the Bonds issued hereunder or intended to be secured hereby, or
for insuring the Property subject to the Lien of the Financing Documents, or
for the value or title of any of the Property subject to the Lien of the
Financing Documents, or for the payment of, or for minimizing taxes, charges,
assessments or Liens upon the same, or otherwise as to the maintenance of the
security hereof, except as to the safekeeping of the pledged collateral and
except that, in the event the Trustee enters into possession of part or all of
the Property subject to the Lien of the Financing Documents pursuant to any
provision thereof, it shall use due diligence in preserving the same, and the
Trustee shall not be bound to ascertain or inquire as to the performance or
observance of any covenant, condition or agreement on the part of the Issuer or





the Company, but the Trustee may require of the Issuer and the Company full
information and advice as to the performance of the covenants, conditions and
agreements aforesaid and as to the condition of the Property subject to the
Lien of the Financing Documents. 

(C)	The Trustee may become the owner of Bonds secured hereby with the same
rights which it would have if not the Trustee. 

(D)	The Trustee shall be protected in acting upon any notice, request,
consent, certificate, order, affidavit, letter, telegram or other paper or
document reasonably believed to be genuine and correct and to have been signed
or sent by the proper Person or Persons. Any action taken by the Trustee
pursuant to the Indenture upon the request or authority or consent of any
Person who at the time of making such request or giving such authority or
consent is the owner of any Bond shall be conclusive and binding upon all
future owners of the same Bond and of any Bond or Bonds issued in exchange
therefore or in place thereof. 

(E)	The Trustee may accept a certificate of the Secretary or Assistant
Secretary of the Issuer under its corporate seal to the effect that a
resolution in the form therein set forth has been adopted by the Issuer as
conclusive evidence that such resolution has been duly adopted and is in full
force and effect. As to the existence or nonexistence of any fact or as to the
sufficiency or validity of any instrument, paper or proceeding, the Trustee
shall be entitled to rely upon a certificate of the Company or the Bank signed
by an Authorized Representative of the Company or the Bank, as the case may be,
or a certificate of an Authorized Representative of the Issuer under seal, as
sufficient evidence of the facts therein contained and, prior to the occurrence
of a default of which it has been notified as provided in paragraph (M) of this
Section or of which by said paragraph it is deemed to have notice, shall also
be at liberty to accept a similar certificate to the effect that any particular
dealing, transaction or action is or is not necessary or expedient, but may at
its discretion, at the reasonable expense of the Company, in every case secure
such further evidence as it may think necessary or advisable, but shall in no
case be bound to secure the same. 

(F)	The permissive right of the Trustee to do things enumerated in the
Indenture shall not be construed as a duty unless so specified herein, and in
doing or not doing so the Trustee shall not be answerable for other than its
own gross negligence or willful misconduct. 

(G)	At any and all reasonable times, the Trustee, and its duly authorized
agents, attorneys, experts, accountants and representatives, shall have the
right fully to inspect all books, papers and records of the Issuer pertaining
to the Project Facility and the Bonds, and to take such memoranda from and in
regard thereto as may be desired. 

(H)	Notwithstanding anything elsewhere in the Indenture, the Trustee shall
have the right, but shall not be required, to demand, in respect of the
authentication of any Bonds, the withdrawal of any moneys, the release of any
interest in Property or any action whatsoever, within the purview of the
Indenture, any showings, certificates, opinions, appraisals or other
information, or corporate action or evidence thereof, in addition to those
required herein. 

(I)	Before taking any action hereunder (except declaring an Event of
Default or drawing under the Letter of Credit on an Interest Payment Date or a
Bond Payment Date), the Trustee may require that a security and indemnity


reasonably satisfactory to it be deposited with it for the reimbursement of all
fees, costs and expenses including, but not limited to, reasonable attorney's
fees to which it may be put and to protect it against all liability, except
liability which is adjudicated to have resulted from its gross negligence or
willful misconduct by reason of any action so taken. 

(J)	All moneys received by the Trustee or any paying agent shall, until
used or applied or invested as herein provided, be held in trust for the
purposes for which they were received, but need not be segregated from other
funds except to the extent required by law or by the Indenture. Neither the
Trustee nor any paying agent shall be under any liability for interest on any
moneys received hereunder except such as may be agreed upon with the Issuer. 

(K)	The Trustee, prior to an Event of Default hereunder and after curing
all Events of Default which may have occurred, undertakes to perform only such
duties as are specifically set forth in the Indenture. In case an Event of
Default has happened which has not been cured, the Trustee shall exercise the
rights, duties and powers vested in it by the Indenture in good faith and with
that degree of diligence, care and skill which ordinarily prudent persons would
exercise under similar circumstances in handling their own affairs. 

(L)	The Trustee shall furnish to the Issuer during the term of this
Indenture upon the written request of the Issuer any reports or other account
of the use of any of the Issuer's funds held by the Trustee that may be
required by any governmental body. 

(M)	The Trustee shall not be required to take notice or be deemed to have
notice of the occurrence of any Event of Default other than an Event of Default
under Section 601(A) through (H), unless the Trustee shall have actual notice
of such Event of Default or unless the Trustee shall be specifically notified
in writing of such Event of Default by the Issuer, the Bank or the Company or
by the owners of at least twenty-five percent (25%) in aggregate principal
amount of Bonds Outstanding hereunder, and all notices or other instruments
required by this Indenture to be delivered to the Trustee must, in order to be
effective, be delivered at the main office of the Trustee, and, in the absence
of such notice so delivered, the Trustee may conclusively assume there is no
Event of Default, except as aforesaid. 

(N)	The Trustee shall not be personally liable for any debts contracted or
for damages to Persons or to personal Property injured or damaged, or for
salaries or nonfulfillment of contracts, during any period in which it may be
in the possession of or managing any Property subject to the Lien of the
Financing Documents as in this Indenture provided. 

(O)	The Trustee shall not be required to give any bond or surety in respect
of the execution of the said trusts and powers or otherwise in respect of the
premises. 

(P)	There shall be no additional fee charged by the Trustee for a draw
under the Letter of Credit as contemplated by Section 408 hereof or by the
terms of the Letter of Credit. Nothing in the foregoing sentence, however,
shall limit the Trustee's right to charge additional fees in the event it is
required to perform Extraordinary Services hereunder. 

(Q)	Before taking any action hereunder, or under the Mortgage or any other
Financing Document, which would result in the Trustee acquiring title to or
taking possession of any portion or all of the Project Facility, the Trustee
may require such environmental inspections and tests of the Project Facility


and other environmental reviews as the Trustee deems necessary and if the
Trustee determines that the taking of title or possession of all or any portion
of the Project Facility will expose it to claims or damages resulting from
environmental or ecological conditions in any way relating to the Project
Facility or any activities at the Project Facility, the Trustee may decline to
take title to or possession of the Project Facility. 

SECTION 702. FEES, CHARGES AND EXPENSES OF TRUSTEE. The Trustee shall be
entitled to payment for its Ordinary Services and Ordinary Expenses, including,
but not limited to, reasonable attorney's fees, rendered or incurred hereunder
and, in the event that it should become necessary for the Trustee to perform
Extraordinary Services, it shall be entitled to reasonable extra compensation
therefor, and to reimbursement for reasonable and necessary Extraordinary
Expenses, including, but not limited to, reasonable attorney's fees, in
connection therewith; provided that, if such Extraordinary Services or
Extraordinary Expenses are occasioned by the gross negligence or willful
misconduct of the Trustee, it shall not be entitled to compensation or
reimbursement therefor. 

SECTION 703. NOTICE TO BONDHOLDERS OF DEFAULT. If an Event of Default occurs of
which the Trustee is, by Section 614 or paragraph (M) of Section 701 hereof,
required to take notice or if notice of an Event of Default has been given to
it as in said Section 614 or paragraph (M) provided, then the Trustee shall
give written notice thereof by mail to all owners of Bonds then Outstanding as
shown on the bond register maintained by the Trustee. 

SECTION 704. INTERVENTION BY TRUSTEE. In any judicial proceeding to which the
Issuer is a party and which in the opinion of the Trustee and its counsel has a
substantial bearing on the interests of Bondholders, the Trustee may intervene
on behalf of Bondholders and shall do so if requested in writing by the owners
of at least twenty-five percent (25%) in aggregate principal amount of all
Bonds then Outstanding if offered the security and indemnity provided for in
Section 701(I). The rights and obligations of the Trustee under this Section
704 are subject to the approval of a court of competent jurisdiction. 

SECTION 705. SUCCESSOR TRUSTEE. Any corporation or association into which the
Trustee may be converted or merged, or with which it may be consolidated, or to
which it may sell or transfer its trust business and assets as a whole or
substantially as a whole, or any corporation or association resulting from any
such conversion, sale, merger, consolidation or transfer to which it is a
party, shall, ipso facto, be and become successor Trustee hereunder and vested
with all of the title to the Trust Revenues and all the trusts, powers,
discretions, immunities, privileges and all other matters as was its
predecessor, without the execution or filing of any instruments or any further
act, deed or conveyance on the part of any of the parties hereto, anything
herein to the contrary notwithstanding. 

SECTION 706. RESIGNATION BY TRUSTEE. The Trustee and any successor Trustee may
at any time resign from the trusts hereby created by giving sixty (60) days'
written notice to the Issuer, the Bank and the Company and by registered or
certified mail to each owner of Bonds then Outstanding and such resignation
shall take effect at the end of such sixty (60) days, but not prior to the
acceptance of appointment by a successor Trustee under Section 709 hereof. Such
notice to the Issuer, the Bank and the Company may be served personally or sent
by registered mail. If an instrument of acceptance by a successor Trustee shall
not be delivered to the Trustee within sixty (60) days after the giving of such
notice of resignation, the resigning trustee may petition any court of
competent jurisdiction for the appointment of a successor Trustee. 


SECTION 707. REMOVAL OF TRUSTEE. (A) The Trustee may be removed at any time, by
an instrument or concurrent instruments in writing delivered to the Trustee,
the Issuer, the Bank and the Company, and signed by the owners of a majority in
aggregate principal amount of all Bonds then Outstanding. Such notice shall
specify the date that such removal shall take effect. 

(B)	No removal of the Trustee under this Section 707 shall be effective
until a successor Trustee shall have been appointed and shall have accepted the
terms and conditions imposed hereby. 

SECTION 708. APPOINTMENT OF SUCCESSOR TRUSTEE BY BONDHOLDERS; TEMPORARY
TRUSTEE. In case the Trustee hereunder shall resign or be removed, or be
dissolved, or shall be in course of dissolution or liquidation, or otherwise
become incapable of acting hereunder, or in case it shall be taken under the
control of any public officer or officers, or of a receiver appointed by a
court, a successor may be appointed by the owners of a majority in aggregate
principal amount of Bonds then Outstanding, by an instrument or concurrent
instruments in writing signed by such owners, or by their duly authorized
attorneys; provided, nevertheless, that in case of vacancy, the Issuer by an
instrument executed and signed by the Chairman or Vice Chairman and attested by
the Secretary or Assistant Secretary of the Issuer under its seal, may appoint
a temporary Trustee to fill such vacancy until a successor Trustee shall be
appointed by such Bondholders in the manner above provided; and any such
temporary Trustee so appointed by the Issuer shall immediately and without
further act be superseded by the Trustee so appointed by such Bondholders.
Every such successor or temporary Trustee appointed pursuant to the provisions
of this Section 708 shall (A) be a trust company or bank organized under the
laws of the United States of America or any state thereof and which is in good
standing, (B) be located within or outside the State, (C) be duly authorized to
exercise trust powers in the State, and (D) maintain a reported capital and
surplus of not less than $5,000,000, or be a subsidiary of a bank holding
company with such capital and surplus. 

SECTION 709. CONCERNING ANY SUCCESSOR TRUSTEE. Every successor Trustee
appointed hereunder shall execute, acknowledge and deliver to its predecessor
and also to the Issuer an instrument in writing accepting such appointment
hereunder, and thereupon such successor, without any further act, deed or
conveyance, shall become fully vested with all the estates, Properties, rights,
powers, trusts, duties and obligations of its predecessor; but such predecessor
shall, nevertheless, on the written request of the Issuer, or of its successor,
and upon payment of all amounts due such predecessor, execute and deliver an
instrument transferring to such successor Trustee all the estates, Properties,
rights, powers and trusts of such predecessor hereunder; and every predecessor
Trustee shall deliver all securities and moneys held by it as Trustee hereunder
to its successor. Should any instrument in writing from the Issuer be required
by a successor Trustee for more fully and certainly vesting in such successor
the estates, Properties, rights, powers and duties hereby vested or intended to
be vested in the predecessor, any and all such instruments in writing shall, on
request, be executed, acknowledged and delivered by the Issuer. The resignation
of any Trustee and the instrument or instruments removing any Trustee and
appointing a successor hereunder, together with all other instruments provided
for in this Article VII, shall be filed and/or recorded by the successor
Trustee in each recording office where the Indenture shall have been filed
and/or recorded. 

SECTION 710. TRUSTEE PROTECTED IN RELYING UPON RESOLUTIONS, ETC. The
resolutions, opinions, certificates and other instruments provided for in the
Indenture may be accepted by the Trustee as conclusive evidence of the facts


and conclusions stated therein and shall be full warrant, protection and
authority to the Trustee for the release of property and the withdrawal of
moneys hereunder. 

SECTION 711. SUCCESSOR TRUSTEE AS TRUSTEE, PAYING AGENT AND BOND REGISTRAR. In
the event of a change in the office of Trustee, the predecessor Trustee which
has resigned or has been removed shall cease to be Trustee and paying agent on
the Bonds and Bond Registrar, and the successor Trustee shall become such
Trustee and paying agent and Bond Registrar. 

SECTION 712. TRUST MAY BE VESTED IN SEPARATE OR CO-TRUSTEE. (A) It is the
purpose of the Indenture that there shall be no violation of any law of any
jurisdiction, including particularly the law of the State, denying or
restricting the right of banking corporations or associations to transact
business as trustee in such jurisdiction. It is recognized that in case of
litigation under the Indenture, and in particular in case of the enforcement of
any such instrument on default, or in case the Trustee deems that by reason of
any present or future law of any jurisdiction it may not exercise any of the
powers, rights or remedies herein granted to the Trustee or hold title to the
trust herein created, or take any other action which may be desirable or
necessary in connection therewith, it may be necessary that the Trustee appoint
an additional individual or institution as a separate or co-trustee. 

(B)	In the event that the Trustee appoints an additional individual or
institution as a separate or co-trustee, each and every remedy, power, right,
claim, demand, cause of action, immunity, estate, title, interest and lien
expressed or intended by the Indenture to be exercised by or vested in or
conveyed to the Trustee with respect thereto shall be exercisable by and vest
in such separate or co-trustee, but only to the extent necessary to enable such
separate or co-trustee to exercise such powers, rights and remedies; and every
covenant and obligation necessary to the exercise thereof by such separate or
co-trustee shall run to and be enforceable by either of them. 

(C)	Should any deed, conveyance or instrument in writing from the Issuer be
required by the separate trustee or co-trustee so appointed by the Trustee for
more fully and certainly vesting in and confirming to him or it such
Properties, rights, powers, trusts, duties and obligations, any and all such
deeds, conveyances and instruments in writing shall, on request, be executed,
acknowledged and delivered by the Issuer. In case any separate trustee or
co-trustee, or a successor to either, shall die, become incapable of acting,
resign or be removed, all the estates, Properties, rights, powers, trusts,
duties and obligations of such separate trustee or co- trustee, so far as
permitted by law, shall vest in and be exercised by the Trustee until the
appointment of a new trustee or successor to such separate trustee or co-
trustee. 

SECTION 713. TRUSTEE TO EXERCISE POWERS OF STATUTORY TRUSTEE. The Trustee shall
be and is hereby vested with all of the rights, powers and duties of a Trustee
which could be appointed by the Bondholders pursuant to Section 878 of the Act,
and the right of the Bondholders to appoint a Trustee pursuant to Section 878
of the Act is hereby abrogated in accordance with the provisions of the Act. 

SECTION 714. NEW YORK REAL PROPERTY LAW. (A) To the extent, if any, that
Article 4-a of the New York Real Property Law, as in effect from time to time,
may apply to this Indenture or the transactions contemplated hereby, then and
in such event, notwithstanding any provision of this Indenture to the contrary,
the following provisions of this Section 714 shall apply to this Indenture. 



(B)	The Trustee shall have, without limitation, the following additional
powers and duties: 

(1)	To receive and collect directly and without the intervention or
assistance of any fiscal agent or other intermediary all payments of monies
required to be made under this Indenture and to disburse the same pursuant to
the terms hereof. 

(2)	To act as tax withholding agent, and to receive, collect and pay the
necessary taxes and hold the surplus, if any, in trust for the rightful owner
thereof. 

(3)	In the event of a default in the payment or deposit of interest,
amortization, taxes, assessments or principal (without any request from the
Bondholders or any of them) with due diligence, prudence and care in its
discretion: 

(a)	to take such action as may be necessary or proper to sequester the
rents and income from the Project Facility and otherwise from the Trust Estate;

(b)	to procure from the owner of the Project Facility and/or of the Trust
Estate an assignment of rents and/or a consent to enter into possession of the
Project Facility and/or the Trust Estate and to collect the rents and income
therefrom; 

(c)	to apply to any court of competent jurisdiction for the appointment of
a receiver of the rents and income from the Project Facility and the Trust
Estate; 

(d)	to declare due and payable forthwith any principal amount remaining due
and unpaid and commence an action to foreclose any Lien on the Project Facility
and/or the Trust Estate; 

(e)	to apply the moneys received as rents and income from the Project
Facility and/or the Trust Estate as well as moneys received by the Trustee from
any receiver appointed for the Project Facility and/or the Trust Estate in his
discretion, to the maintenance and operation of such Trust Estate, the payment
of taxes, water rents and assessments levied thereon and any arrears thereof,
to the payment of underlying Liens, and to the creation and maintenance of a
reserve or sinking fund, and after the commencement of an action to foreclose
any Lien on the Project Facility and/or the Trust Estate, to distribute ratably
among the Bondholders any moneys remaining in its hands; and 

(f)	to render annually to the Bondholders, after the occurrence of an Event
of Default, unless such Event of Default be previously cured, a summarized
statement of income and expenditures in connection with the Trust Estate. 

(4)	To permit the Issuer or other Person in possession or control of the
Project Facility and/or the Trust Estate, or its successors in interest, to be
free to select the insurance broker or agent through whom any insurance of any
kind is to be placed or written on any property affected or covered by a
mortgage held by such Trustee. 

(C)	The powers and duties conferred and imposed in subsection (B) of this
Section 714 shall be in addition to those conferred and imposed by other
provisions of this Indenture and, in case of a conflict, the provisions of said
subsection (B) shall prevail; provided, however, that if Article 4-A of the
Real Property Law of the State (or any successor provision) or any portion


thereof should at any time be repealed or should be construed by a non-
appealable judicial decision of a State or Federal court specifically to be
inapplicable to this Indenture, said subsection (B) or the corresponding
provisions of said subsection (B), as the case may be, shall cease to have any
further force and effect; provided, further, that any modification of the
powers and duties of a trustee pursuant to Article 4-A of the Real Property Law
of the State shall be incorporated by reference herein as part of said
subsection (B). 

SECTION 715. CONFLICTS OF INTEREST. (A) To the extent, if any, that Article 4-
A of the New York Real Property Law, as in effect from time to time, may apply
to this Indenture or the transactions contemplated hereby, then and in such
event, notwithstanding any provision of this Indenture to the contrary, the
following provisions of this Section 715 shall apply to this Indenture. If the
Trustee has or shall acquire any conflicting interest as hereinafter defined: 

(1)	the Trustee shall, within ninety (90) days after ascertaining that it
has such conflicting interest, either eliminate such conflicting interest or
resign, such resignation to become effective upon the appointment of a
successor trustee and such successor's acceptance of such appointment; and the
Issuer shall take prompt steps to have a successor appointed in the manner
provided in this Indenture; 

(2)	in the event that the Trustee shall fail to comply with the provisions
of paragraph (1) of this subsection (A), the Trustee shall, within ten (10)
days after the expiration of such ninety-day period, transmit notice of such
failure by mail (a) to all registered Holders of Bonds, as the names and
addresses of such Holders appear upon the registration books of the Issuer, (b)
to such Holders of Bonds as have, within the two (2) years preceding such
transmission, filed their names and addresses with the Trustee for the purpose
of receiving notices or reports to Holders of Bonds and (c) to all Holders of
Bonds whose names and addresses are contained in information currently
preserved by the Trustee for such purpose in accordance with subsection (G) of
this Section 715; and 

(3)	any Holder of Bonds who has been a bona fide Holder thereof for at
least six (6) months may, on behalf of himself and all others similarly
situated, petition any court of competent jurisdiction for the removal of the
Trustee, and the appointment of a successor, if the Trustee fails, after
written request therefor by such Holder, to comply with the provisions of
paragraph (1) of this subsection (A). 

(B)	For purposes of subsection (A) of this Section 715, the Trustee shall
be deemed to have a conflicting interest if: 

(1)	the Trustee is trustee under another mortgage, deed of trust, trust
indenture or other similar instrument (hereinafter in this Section 715 referred
to as an "indenture") under which any other securities, or certificates of
interest or participation in any other securities, of an obligor upon the Bonds
are outstanding unless (1) such other indenture is a collateral trust indenture
under which the only collateral consists of Bonds issued under this Indenture,
or (2) such obligor has no substantial unmortgaged assets and is engaged
primarily in the business of owning, or of owning and developing or operating,
real estate, and this Indenture and such other indenture are secured by wholly
separate and distinct parcels of real estate; provided, however, that there





shall be excluded from the operation of this paragraph any other indenture or
indentures which shall have been qualified with the United States Securities
and Exchange Commission pursuant to the provisions of the Trust Indenture Act
of 1939, as from time to time amended and in force; 

(2)	the Trustee or any of its directors or executive officers is an obligor
upon the Bonds or an underwriter for such an obligor; 

(3)	the Trustee directly or indirectly controls, or is directly or
indirectly controlled by or is under direct or indirect common control with, an
obligor upon the Bonds or an underwriter for such an obligor; 

(4)	the Trustee or any of its directors or executive officers is a
director, officer, partner, employee, appointee or representative of an obligor
upon the Bonds, or of an underwriter (other than the Trustee itself) for such
an obligor who is currently engaged in the business of underwriting, except
that (a) one individual may be a director or an executive officer of the
Trustee and a director or an executive officer of such obligor, but may not be
at the same time an executive officer of both the Trustee and of such obligor,
and (b) if and so long as the number of directors of the Trustee in office is
more than nine, one additional individual may be a director or an executive
officer of the Trustee and a director of such obligor, and (c) the Trustee may
be designated by any such obligor or by any underwriter for any such obligor to
act in the capacity of transfer agent, registrar, custodian, paying agent,
fiscal agent, escrow agent or depositary, or in any other similar capacity, or,
subject to the provisions of paragraph (1) of this subsection (B), to act as

underwriter for any such obligor;

companies or banking firms, or any certificate of interest or participation in
any such note or evidence of indebtedness; (2) an obligation shall be deemed to
be "in default" when a default in payment of principal shall have continued for

collateral security (as trustee or otherwise) for an obligation which is not in
default as above defined, or (b) any security which it holds as collateral
security under this Indenture, irrespective of any default thereunder, or (c)

issuer with a view to, or offers or sells for an issuer in connection with, the

execution by the Issuer and the Trustee of such indenture or indentures
supplemental hereto as shall be deemed necessary and desirable by the Issuer or
the Trustee for the purpose of modifying, altering, amending, adding to or
rescinding, in any particular, any of the terms or provisions contained in the
Indenture or in any supplemental indenture; provided, however, that nothing
contained in this Section 802 shall permit or be construed as permitting (1)
without the consent of the holder of such Bond, (a) a reduction in the rate, or
extension of the time of payment, of interest on any Bond, (b) a reduction of
any premium payable on the redemption of any Bond, or an extension of time for
such payment, or (c) a reduction in the principal amount payable on any Bond,

consent of the holders of all the Bonds at the time Outstanding which would be
affected by the action to be taken, (4) the modification of the rights, duties
or immunities of the Trustee, without the written consent of the Trustee, or

such supplemental indenture for any of the purposes specified in this Section
802, the Trustee shall, upon being satisfactorily secured and indemnified as

such supplemental indenture shall have consented to and approved the execution
thereof as herein provided, no holder of any Bond shall have any right to
object to any of the terms and provisions contained therein, or the operation
thereof, or in any manner to question the propriety of the execution thereof,

of any such supplemental indenture as in this Section 802 permitted and
provided, the Indenture shall be and be deemed to be modified and amended in
accordance therewith. 



(C)	The Issuer and the Trustee may rely upon an opinion of Independent
Counsel as conclusive evidence that the execution and delivery of a
supplemental indenture has been effected in compliance with the provisions of
this Section 802. 

SECTION 803. SUPPLEMENTAL INDENTURES; CONSENT OF BANK. Notwithstanding anything
to the contrary herein contained, the Issuer and the Trustee shall in no event
enter into any indenture supplemental to the Indenture under Section 802 hereof

Bank as counsel to the Trustee may require that the Bank's obligations under
the Letter of Credit have not been diminished or otherwise affected by such
supplemental indenture. The Issuer and the Trustee shall be entitled to rely
upon such certificates or opinions delivered by the Bank or its counsel to such
effect. 

SECTION 804. SUPPLEMENTAL INDENTURES; CONSENT OF COMPANY. Notwithstanding
anything contained in this Indenture to the contrary, no supplemental indenture

and delivery of such supplemental indenture. In this regard, the Trustee shall
cause notice of the proposed execution and delivery of any such supplemental
indenture to be mailed by certified or registered mail to the Company at least
fifteen (15) days prior to the proposed date of execution and delivery of any

request, direction, approval, waiver, objection, appointment or other
instrument required by the Indenture to be signed and executed by the
Bondholders may be signed and executed in any number of concurrent writings of
similar tenor and may be signed or executed by such Bondholders in person or by
agent appointed in writing. Proof of the execution of any such instrument, if
made in the following manner, shall be sufficient for any of the purposes of
the Indenture, and shall be conclusive in favor of the Trustee with regard to
any action taken under such instrument, namely: 

(A)	The fact and date of the execution by any Person of any such instrument
may be proved by the affidavit of a witness of such execution or by the
certificate of any notary public or other officer of any jurisdiction,
authorized by the laws thereof to take acknowledgements of deeds, certifying to
the execution thereof. Where such execution is by an officer of a corporation
or association or a member of a partnership on behalf of such corporation,
association or partnership, such affidavit or certificate shall also constitute
sufficient proof of his authority. 

(B)	The ownership of Bonds shall be proven by the bond register. 

(C)	Any request, consent or vote of the holder of any Bond shall bind every
future holder of the same Bond and the holder of every Bond issued in exchange
therefor or in lieu thereof, in respect of anything done or permitted to be
done by the Trustee or the Issuer pursuant to such request, consent or vote.

waiver under the Indenture, Bonds which are owned by the Issuer, the Company,
the Bank or by any Person directly or indirectly controlling or controlled by
or under direct or indirect common control with the Issuer, the Bank or the
Company shall be disregarded and deemed not to be Outstanding for the purposes
of determining whether the Trustee shall be protected in relying on any such
demand, request, direction, consent or waiver. Only Bonds which the Trustee
knows to be so owned shall be disregarded. Bonds so owned which have been
pledged in good faith may be regarded as Outstanding for the purposes of this
Section 1101 if the pledgee shall establish to the satisfaction of the Trustee
the pledgee's right to vote such Bonds. In case of a dispute as to such right,
any decision by the Trustee taken upon the advice of counsel shall be full
protection to the Trustee. 

SECTION 1102. LIMITATION OF RIGHTS. With the exception of rights herein
expressly conferred, nothing expressed or to be implied from the Indenture or

the obligations and agreements of the Issuer, and not of any member, officer,
director, agent (other than the Company) or employee of the Issuer in his
individual capacity, and the members, officers, directors, agents (other than
the Company) and employees of the Issuer shall not be liable personally hereon
or be subject to any personal liability or accountability based upon or in
respect hereof or thereof or of any transaction contemplated hereby or thereby.

(B)	The obligations and agreements of the Issuer contained herein shall not
constitute or give rise to any obligations of the Town of Colonie, New York or
the State and neither the Town of Colonie, New York nor the State shall be
liable thereon, and further, such obligations and agreements shall not
constitute or give rise to a general obligation of the Issuer, but rather shall
constitute limited obligations of the Issuer payable solely from the revenues
of the Issuer derived and to be derived from the sale or other disposition of
the Project Facility (except for revenues derived by the Issuer with respect to
the Unassigned Rights). 

(C)	No order or decree of specific performance with respect to any of the
obligations of the Issuer hereunder (other than pursuant to Section 602 hereof,
and then only to the extent of the Issuer's obligations thereunder) shall be
sought or enforced against the Issuer unless the party seeking such order or
decree shall first have complied with Section 516 hereof. 

(D)	The Issuer shall be entitled to the advice of counsel (who may be
counsel to any party or to any Bondholder) and shall be wholly protected as to
any action taken or omitted to be taken in good faith in reliance on such
advice. The Issuer may rely conclusively on any notice, certificate or other
document furnished to it under any Financing Document and reasonably believed
by it to be genuine. The Issuer shall not be liable for any action taken by it
in good faith and reasonably believed by it to be within the discretion or
power conferred upon it, or in good faith omitted to be taken by it and
reasonably believed to be beyond such discretion or power, or taken by it
pursuant to any direction or instruction by which it is governed under any
Financing Document, or omitted to be taken by it by reason of the lack of
direction or instruction required for such action under any Financing Document,
and shall not be responsible for the consequences of any error of judgment
reasonably made by it. When any payment, consent or other action by the Issuer
is called for by the Indenture, the Issuer may defer such action pending an
investigation or inquiry or receipt of such evidence, if any, as it may require
in support thereof. A permissive right or power to act shall not be construed




as a requirement to act, and no delay in the exercise of a right or power shall
affect the subsequent exercise thereof. The Issuer shall in no event be liable
for the application or misapplication of funds or for other acts or defaults by
any Person except by its own members, officers and employees. 

(E)	In approving, concurring in or consenting to any action or in
exercising any discretion or in making any determination under the Indenture,
the Issuer may consider the interests of the public, which shall include the
anticipated effect of any transaction on tax revenues and employment, as well
as the interests of the other parties hereto and the Bondholders; provided,
however, that nothing herein shall be construed as conferring on any Person
other than the Trustee, the Bank and the Bondholders any right to notice,
hearing or participation in the Issuer's consideration, and nothing in this
Section 1109 shall be construed as conferring on any of them any right
additional to those conferred elsewhere herein. Subject to the foregoing, the
Issuer shall not unreasonably withhold any approval or consent to be given by
it hereunder. 

SECTION 1110. ASSIGNMENT TO BANK. In the event the Trustee receives moneys
drawn under the Letter of Credit in an amount sufficient to pay in full the
principal of, premium, if any, and interest on the Bonds then Outstanding, the
Trustee shall execute and deliver to the Bank an instrument assigning the Bank
all of its right, title and interest to, in and under the Financing Documents. 

SECTION 1111. NOTICES TO RATING AGENCY.

following events occur: 

(1)	any expiration, termination, substitution or extension relating to the
Letter of Credit or any Substitute Letter of Credit;

TAXABLE INDUSTRIAL DEVELOPMENT REVENUE BOND

(MECHANICAL TECNOLOGY INCORPORATED PROJECT - LETTER OF CREDIT SECURED), SERIES
1998A 

NO.: R-1	$6,000,000 

MATURITY DATE: December 1, 2013 

DATED: December 17, 1998	CUSIP: 196210 GN2 

Town of Colonie Industrial Development Agency, a public benefit corporation of
the State of New York (the "Issuer"), for value received, hereby promises to
pay, solely from the sources hereinafter described, to Cede & Co. or registered
assigns, on the Maturity Date identified above (subject to any right of prior
redemption hereinafter provided for), the principal sum of Six Million Dollars
(subject to reduction as hereinafter provided) and interest thereon (computed
on the basis of a 365 or 366-day year for the actual number of days elapsed)
from the date set forth above, or from the most recent Interest Payment Date to
which interest has been paid, to the Maturity Date identified above (or such
earlier date on which the principal hereof has been paid or duly provided for),
at the rate described below, on the first Thursday of each month (each an
"Interest Payment Date"), commencing January 7, 1999. The principal of this
Bond shall be paid on the Maturity Date upon presentation and surrender hereof
at the Office of Manufacturers and Traders Trust Company, as trustee (together
with its successors in trust, the "Trustee") under the trust indenture dated as
of December 1, 1998 (from time to time, as amended or supplemented, the
"Indenture") by and between the Issuer and the Trustee, or at the duly
designated office of any successor trustee under the Indenture. The
installments of interest described above shall, as provided in the Indenture,
be paid to the Person in whose name this Bond (or one or more Predecessor
Bonds, as defined in the Indenture) is registered at the close of business on
the Business Day next preceding any Interest Payment Date (the "Regular Record
Date"), and shall be paid by check or draft of the Trustee mailed by the
Trustee on such Interest Payment Date to such registered owner at his address
appearing on the registration books of the Issuer, or at the option of any
holder of Bonds in an aggregate principal amount of $250,000 or greater be
transmitted on such Interest Payment Date by wire transfer at such owner's
written request to the bank account number on file with the Trustee. Any such
interest not so punctually paid or duly provided for shall forthwith cease to
be payable to the registered owner on such Regular Record Date, and may be paid
to the Person in whose name this Bond (or one or more Predecessor Bonds) is
registered at the close of business on a date for the payment of such defaulted
interest to be fixed by the Trustee (the "Special Record Date"), notice whereof
being given to registered owners of the Bonds not less than ten (10) days prior
to such Special Record Date, or may be paid in any other lawful manner as shall
be determined by the Trustee. The principal of, premium, if any, on and
interest on this Bond are payable in lawful money of the United States of
America. 

(Calculation of Interest) 

This Bond shall bear interest as follows: 

(a)	From the Closing Date through and including December 23, 1998, the
Bonds shall bear interest at a rate per annum equal to five and fifty-five
hundredths percent (5.55%). 



(b)	Thereafter, except as provided in (e) below, this Bond (other than
Pledged Bonds) shall bear interest at the "Adjustable Rate". 

(i)	The Adjustable Rate shall be the rate of interest established by the
Remarketing Agent on the first Business Day prior to each Adjustment Date,
which in the Remarketing Agent's reasonable judgment would result, as nearly as
practicable, in the market value of this Bond on an Adjustment Date being equal
to one hundred percent (100%) of the principal amount thereof. The Adjustable
Rate so determined shall be adjusted in accordance with the directions of the
Remarketing Agent on the Adjustment Date and shall remain in effect through and
including the day prior to the next following Adjustment Date. 

(ii)	In determining the Adjustable Rate pursuant to the foregoing paragraph
(b)(i), the Remarketing Agent shall take into account, to the extent
applicable, (A) the market interest rates for comparable securities held by
open-end municipal or other fixed income bond funds or other institutional or
private investors with substantial portfolios (w) with interest rate adjustment
periods and demand purchase options substantially identical to the Bonds, (x)
bearing interest at a variable rate intended to maintain par value, (y) rated
by a national credit rating agency in the same category as the Bonds or, if not
rated, secured by substantially the same level of security as the Bonds, and
(z) the interest on which is included in gross income of the holders thereof
for federal income taxation purposes; (B) other financial market rates and
indices which may have a bearing on the Adjustable Rate (including, but not
limited to rates borne by commercial paper, commercial paper, Treasury bills,
commercial bank prime rates, certificate of deposit rates, federal funds rates,
the London Interbank Offered Rate, indices maintained by The Bond Buyer, and
other publicly available taxable interest rate indices); (C) general financial
market conditions (including current forward supply); (D) factors particular to
the Project or the credit standing of the Company and the Bank; and (E) such
other factors which the Remarketing Agent deems appropriate. 

(iii)	On the Business Day prior to each Adjustment Date, the Remarketing
Agent shall notify the Trustee, by Immediate Notice, of the Adjustable Rate. 

(c)	If for any reason the position of Remarketing Agent is vacant or the
Remarketing Agent fails to act, the Adjustable Rate shall be determined by a
third party selected by the Company at the Company expense and shall be equal
to one hundred percent (100%) of the yield applicable to 13 week United States
Treasury bills determined by such third party on the basis of the average per
annum discount rate at which such 13- week Treasury bills shall have been sold
(1) at the most recent Treasury auction conducted during the immediately
preceding Adjustment Period, (2) if no such auction shall have been conducted
during the immediately preceding Adjustment Period, at the most recent Treasury
auction conducted prior to such preceding Adjustment Period, plus fifty (50)
basis points; provided, however, that in the event the Company notifies the
Trustee that an index (as published in The Wall Street Journal) of seven-day
yield evaluations at par of issuers of securities, the interest on which is
includable in gross income for federal income tax purposes, and of comparable
rating to the rating on the Bonds, published by any nationally recognized
municipal securities evaluation service is available, the Adjustable Rate shall
be determined by the Trustee and shall be equal to such index. 

(d)	The Adjustable Rate shall be calculated based on a 365 or 366- day year
for the actual number of days elapsed. Further, each determination of the
Adjustable Rate pursuant to and in accordance with the foregoing terms of the
Indenture and the terms of this Bond shall be conclusive and binding on the
Issuer, the Trustee, the Company, the Bank, and the holder of this Bond. 


(e)	(i) From and after the Conversion Date through the maturity or earlier
redemption of the Bonds, this Bond shall bear interest at the Fixed Rate, which
shall be a fixed rate (or rates) of interest established by the Remarketing
Agent at least fifteen (15), but not more than thirty (30) days prior to the
Conversion Date, which in the reasonable judgment of the Remarketing Agent
would result, as nearly as practicable, in the market value of this Bond on the
Conversion Date being equal to one hundred percent (100%) of the principal
amount thereof. 

(ii)	(A) At the Remarketing Agent's discretion, after the exercise of the
Conversion Option, the Bonds may be converted into serial bonds, with a
principal amount of Bonds maturing on a Principal Payment Date each year equal
to the principal amount required to be redeemed as set forth in Section 301(E)
of the Indenture. In such event, each maturity of Bonds may bear a different
interest rate, each of which shall be determined by the Remarketing Agent in
the same manner as the Fixed Rate (for convenience each such rate shall be
referred to as the Fixed Rate); provided, however, that in no event shall the
Remarketing Agent be permitted to convert the Bonds into serial bonds as
described above without delivering to the Trustee an opinion of Bond Counsel
that such conversion is lawful under the Act and permitted under the Indenture.

(B)	The Interest Payment Dates after the exercise of the Conversion Option
shall be semi-annual, with one Interest Payment Date being the first day of the
month preceding the Fixed Rate Conversion Date and the other Interest Payment
Date being the first day of the month six (6) months later. Principal shall be
payable annually thereafter in the amounts and the years set forth in Section
301(E) hereof on the Principal Payment Dates. 

(iii)	In determining the Fixed Rate, the Remarketing Agent shall take into
account, to the extent applicable, (A) market interest rates for comparable
securities which are held by open-end municipal or other fixed income bond
funds or other institutional or private investors with substantial portfolios
(w) with a term equal to the period to maturity remaining on the Bonds, (x) the
interest on which is included in the gross income of the holders thereof for
federal income tax purposes, (y) rated by a national credit rating agency in
the same rating category as the Bonds, or, if not rated, secured by
substantially the same level of security as the Bonds, and (z) with redemption
provisions similar to those which have bearing on the Fixed Rate; (B) other
financial market rates and indices (including but not limited to rates borne by
industrial development bonds, other taxable revenue bonds, Treasury
obligations, commercial bank prime rates, certificate of deposit rates, federal
funds rates, indices maintained by The Bond Buyer and other publicly available
taxable interest rates and indices); (C) general financial market conditions
(including current forward supply); (D) factors particular to the Project or
the credit standing of the Company and the Bank; and (E) such other factors
which the Remarketing Agent deems appropriate. 

(iv)	The Fixed Rate shall be calculated based on a 360-day year of twelve
30-day months. The determination of the Fixed Rate by the Remarketing Agent
pursuant to and in accordance with the terms of the Indenture and the terms of
this Bond shall be conclusive and binding on the Issuer, the Trustee, the
Company, the Bank and the holder of this Bond. 

(v)	To exercise the Conversion Option, the Company shall deliver at least
sixty (60) days prior to the Conversion Date, written notice to the Trustee,
the Issuer and the Bank of its election of the Conversion Option. On the
Conversion Date, this Bond shall be subject to a Mandatory Tender for purchase
as provided in Section 304 of the Indenture. Notwithstanding anything to the


contrary contained herein, such notice shall not be effective unless the Bank
shall have consented thereto in writing and such notice is accompanied by: 

(A)	a Substitute Letter of Credit with an expiration date of not earlier
than fifteen (15) days following the Principal Payment Date which is at least
three (3) years after the next succeeding Principal Payment Date and in an
amount equal to the sum of the aggregate principal amount of the Bonds then
Outstanding, 210 days' interest thereon computed at the Fixed Rate, together
with the Optional Redemption Premium; provided, however, that if the Letter of
Credit then in place has an expiration date of not earlier than fifteen (15)
days following the Principal Payment Date which is at least three (3) years
after the next succeeding Principal Payment Date and in an amount equal to the
aggregate principal amount of the Bonds then Outstanding, 210 days' interest
thereon computed at the Fixed Rate, together with the Optional Premium, no
Substitute Letter of Credit need be obtained; 

(B)	a statement as to whether the Bonds shall be serial bonds as set forth
in paragraph (e)(ii) above; and 

(C)	an opinion of Bond Counsel reasonably satisfactory to the Trustee, the
Issuer and the Bank to the effect that the exercise of the Conversion Option is
lawful under the Act and permitted by the Indenture. 

(f)	Notwithstanding anything herein to the contrary, any Pledged Bond shall
bear interest at a rate equal to the Bank Rate, as such rate shall change from
time to time; provided, however, that at no time shall the interest rate in
effect for any Pledged Bond exceed the maximum rate permitted by applicable
usury laws. 

(g)	Notwithstanding anything herein to the contrary, in no event will the
rate of interest borne by any Bond (except any Bond constituting a Pledged
Bond) exceed fifteen percent (15%) per annum. 

(h)	The Issuer hereby appoints the Company to act as agent of the Issuer
for purposes of exercising the Conversion Option, all as set forth in the
Indenture, and subject to compliance with the terms and provisions of the
Indenture. 

(Conversion Option) 

In the event the Company exercises the Conversion Option with respect to the
Bonds, on the Conversion Date all Bonds which have not been called for
redemption shall be subject to Mandatory Tender by the owners thereof on the
Conversion Date. Notwithstanding the foregoing, each Bondholder may, by
delivery to the Trustee for receipt at least twenty (20) days immediately
preceding the Conversion Date of an irrevocable election not to tender, elect
to continue to hold its Bonds (or portions thereof) past the Conversion Date at
a Fixed Rate to be in effect at such time. Such notice shall be in
substantially the form of Exhibit C-2 attached to the Indenture. Not earlier
than sixty (60) days prior to the Conversion Date or later than thirty (30)
days prior to the Conversion Date, the Trustee shall send a notice to the
owners of all Outstanding Bonds which have not been called for redemption, in
substantially the form of Exhibit C-1 attached to the Indenture. Such notice
shall describe (a) the terms of the Mandatory Tender, (b) the right of the
owner to elect not to tender, (c) the Letter of Credit to be in effect
following the Mandatory Tender, (d) the right of the owner of Bonds in an
aggregate amount of $200,000 or more to elect not to tender the total principal
amount and to continue to hold a portion of its Bonds (but in no event may


either the amount tendered or the amount not tendered be any amount other than
$100,000, or any integral multiple of $5,000 in excess thereof), and (e) that
the rating then in effect with respect to the Bonds, if any, may be withdrawn
or lowered. 

In the event that prior to the Conversion Date of the Bonds the Company shall
deliver notice to the Trustee at least sixty (60) days prior to the expiration
of the Letter of Credit or Substitute Letter of Credit securing such Bonds of
its intent to deliver an Alternate Letter of Credit in substitution for such
Letter of Credit or Substitute Letter of Credit, all Bonds secured by such
Letter of Credit which have not been called for redemption shall be subject to
Mandatory Tender by the owner thereof on the Alternate Security Date.
Notwithstanding the foregoing, each Bondholder may, by delivery to the Trustee
for receipt at least twenty (20) days immediately preceding any Alternate
Security Date of an irrevocable election not to tender, elect to continue to
hold its Bonds past the respective Alternate Security Date. Such notice shall
be in substantially the form of Exhibit C-4 attached to the Indenture. 

Not earlier than sixty (60) days prior to the Alternate Security Date or later
than thirty (30) days prior to the Alternate Security Date, the Trustee shall
send a notice to the owners of all Outstanding Bonds which have not been called
for redemption, in substantially the form of Exhibit C-3 attached to the
Indenture. Such notice shall describe (1) the terms of the Mandatory Tender,
(2) the right of the owner to elect not to tender, (3) a brief description of
the Alternate Letter of Credit and the identity of the Substitute Bank issuing
the Alternate Letter of Credit, (4) the right of the owner of Bonds in an
aggregate amount of $200,000 or more to elect not to tender the total principal
amount and to continue to hold a portion of its Bonds (but in no event may
either the amount tendered or the amount not tendered be any amount other than
$100,000, or any integral multiple of $5,000 in excess thereof) and (5) that
the rating then in effect with respect to the Bonds secured by such Alternate
Letter of Credit will be withdrawn or lowered. 

Owners of Bonds required to be tendered who do not provide the Trustee with the
notice of their election not to tender as described above shall be required to
deliver their Bonds to the Trustee for purchase at the Purchase Price on the
Conversion Date or the Alternate Security Date, as the case may be, with an
appropriate endorsement for transfer or accompanied by a bond power endorsed in
blank. Any such Bonds not so delivered on such Conversion Date or the Alternate
Security Date, as the case may be ("Undelivered Bonds"), for which there has
been irrevocably deposited in trust with the Trustee an amount of moneys
sufficient to pay the Purchase Price of the Undelivered Bonds, shall be deemed
to have been purchased. 

IN THE EVENT OF A FAILURE BY AN OWNER OF BONDS REQUIRED TO BE TENDERED (OTHER
THAN AN OWNER OF BONDS WHO HAS GIVEN NOTICE OF ITS ELECTION NOT TO TENDER AS
PROVIDED ABOVE) TO DELIVER ITS BONDS ON OR PRIOR TO THE CONVERSION DATE OR THE
ALTERNATE SECURITY DATE, SAID OWNER SHALL NOT BE ENTITLED TO ANY PAYMENT
(INCLUDING ANY INTEREST TO ACCRUE ON OR SUBSEQUENT TO SUCH CONVERSION DATE OR
THE ALTERNATE SECURITY DATE) OTHER THAN THE PURCHASE PRICE FOR SUCH UNDELIVERED
BONDS, AND ANY UNDELIVERED BONDS SHALL NO LONGER BE ENTITLED TO THE BENEFITS OF
THE INDENTURE, EXCEPT FOR THE PURPOSE OF PAYMENT OF THE PURCHASE PRICE
THEREFOR. 

(Demand Purchase Option) 





This Bond shall be purchased, at the option ("Demand Purchase Option") of the
Owner hereof, at a price (the "Purchase Price") equal to one hundred percent
(100%) of the principal amount hereof plus accrued and unpaid interest hereon
to the Repurchase Closing Date (as hereinafter defined), upon: 

(A)	Delivery to, and receipt by, the Tender Agent at its designated
address, or the Trustee at the address set forth herein on a Business Day of a
written notice ("Bondholder's Tender Notice") which requests the purchase of
the Bond. The Tender Notice shall be in substantially the form of Exhibit C-5
to the Indenture. Such Tender Notice shall provide the following information:
(1) the principal amount of such Bond or portion thereof to be purchased (the
"Tendered Bond"), which portion shall be $100,000 or an integral multiple of
$5,000 in excess thereof; provided, however, that no portion of a Tendered Bond
shall be purchased if it results in the unpurchased portion of the Tendered
Bond being less than $100,000, (2) the number of the Tendered Bond, (3) the
date on which the Tendered Bond shall be purchased, which date shall be a
Business Day at least seven (7) calendar days following the receipt by the
Trustee or the Tender Agent of the Bondholder's Tender Notice (the "Repurchase
Closing Date"), (4) the name and address of the Bondholder, (5) an irrevocable
request of such purchase, and (6) an undertaking of the Bondholder to deliver
the Bond to the Tender Agent or the Trustee in accordance with (B) below; and 

(B)	Delivery of the Tendered Bond, at the office of the Trustee or Tender
Agent at or prior to 10:00 a.m., New York City time, on the Repurchase Closing
Date with an appropriate endorsement for transfer or accompanied by a bond
power endorsed in blank; provided, however, the Tendered Bond shall only be
deemed properly tendered hereunder if the Tendered Bond delivered to the Tender
Agent or the Trustee conforms in all respects to the description thereof in the
Bondholder's Tender Notice; and 

(C)	In the event the Tender Agent or the Trustee, as the case may be,
determines that the Bondholder's Tender Notice is defective in any respect
whatsoever, the Tender Agent or the Trustee, as the case may be, shall
immediately notify the Bondholder tendering the Bond; and 

(D)	Bonds which are the subject of a Bondholder's Tender Notice described
in (A) above, but which are not tendered in accordance with (B) above, shall be
deemed tendered and all rights of the holder thereof shall be satisfied from
the deposit with the Tender Agent or the Trustee of the Purchase Price thereof
and the Tender Agent or the Trustee, as the case may be, shall hold such
Purchase Price in trust for the benefit of such holder until the Bonds
purchased with such moneys shall have been delivered to or for the account of
such Holder. Holders of Tendered Bonds to be tendered which are not delivered
to the Tender Agent or the Trustee by the holder thereof shall have no further
rights with respect to such Bonds except to receive payment of the Purchase
Price therefor upon surrender of such Bonds to the Tender Agent or the Trustee.

Notwithstanding the foregoing, the Bondholders shall have no Demand Purchase
Option described herein if (A) there shall have occurred and be continuing an
Event of Default under the Indenture, except for an Event of Default under
Section 601(I) of the Indenture or (B) the Fixed Rate is in effect for the
Bonds being held by such Bondholder. 

Furthermore, no Bondholder shall have the right to exercise a Demand Purchase
Option with respect to those Bonds for which a notice of redemption has been
mailed by the Trustee. 

(Project Description) 


This Bond is one of a duly authorized issue of bonds of the Issuer designated
"Town of Colonie Industrial Development Agency Taxable Industrial Development
Revenue Bonds (Mechanical Technology Incorporated Project - Letter of Credit
Secured), Series 1998A" in the aggregate principal amount of $6,000,000 (the
"Bonds"). The Bonds are issued for the purpose of assisting in providing
financing to the Issuer for a project (the "Project") consisting of the
following: (A) (1) the acquisition of a leasehold interest in a parcel of land
containing approximately 35.6 acres located at 968 Albany-Shaker Road in the
Town of Colonie, Albany County, New York (the "Land"), together with the
existing buildings located thereon which contain approximately 98,000 square
feet in the aggregate (such buildings known individually as Building I,
Building II and Building III and hereinafter collectively referred to as the
"Existing Facility"), (2) the demolition of Building I which contains
approximately 14,105 square feet of space, (3) the construction of a new
building to replace Building I and which will contain approximately 32,000
square feet of space (the "New Facility") (the Existing Facility and the New
Facility hereinafter collectively referred to as the "Facility"), (4) the
renovation of Building III and (5) the acquisition of and installation therein
and thereon of certain machinery and equipment (the "Equipment") (the Land, the
Facility and the Equipment being hereinafter collectively referred to as the
"Project Facility"), all of the foregoing to be occupied by Mechanical
Technology Incorporated (the "Company") and operated as a manufacturing
facility, a portion of which will be leased by the Company to Plug Power, LLC
and operated as a facility for the manufacture, research and development of
fuel cells for residential and automotive applications and related products and
any other related activities; (B) the financing of all or a portion of the
costs of the foregoing by the issuance of the Bonds; (C) the granting of
certain other "financial assistance" (within the meaning of Section 854(14) of
the Act) with respect to the foregoing, including exemption from certain sales
taxes, deed transfer taxes, mortgage recording taxes and real property taxes
(collectively with the Bonds, the "Financial Assistance"); and (D) the lease
(with an obligation to purchase) or sale of the Project Facility to the Company
or such other person as may be designated by the Company and agreed upon by the
Agency. The Project Facility is to be sold by the Issuer to the Company
pursuant to the provisions of an installment sale agreement dated as of
December 1, 1998 (the "Installment Sale Agreement") by and between the Issuer
and the Company. 

The Bonds are issued under and are equally and ratably secured by the
Indenture. The Indenture grants the Trustee a first security interest in the
Trust Revenues (as defined in the Indenture). 

In order to provide additional security for the Bonds, the Company has entered
into an irrevocable letter of credit and reimbursement agreement dated as of
December 1, 1998 (the "Reimbursement Agreement") with KeyBank National
Assocation (the "Bank"), pursuant to which the Bank has issued in favor of the
Trustee an irrevocable transferable direct pay letter of credit (the "Letter of
Credit"), issued in an amount equal to the Credit Amount (as defined in the

whole multiple of $5,000; provided, however, that no $5,000 portion of a Bond
shall be redeemed if it results in the unredeemed portion of the Bond being
less than $100,000.

limitations therein set forth, this Bond, upon surrender for transfer at the
principal office of the Trustee as Bond Registrar, is transferable upon an
assignment duly executed by the registered owner hereof or his duly authorized

"Town of Colonie Industrial Development Agency Taxable Industrial Development
Revenue Bonds (Mechanical Technology Incorporated Project - Letter of Credit
Secured), Series 1998A" in the aggregate principal amount of $6,000,000 (the
"Bonds"). The Bonds are issued for the purpose of assisting in providing
financing to the Issuer for a project (the "Project") consisting of the
following: (A) (1) the acquisition of a leasehold interest in a parcel of land
containing approximately 35.6 acres located at 968 Albany-Shaker Road in the
Town of Colonie, Albany County, New York (the "Land"), together with the
existing buildings located thereon which contain approximately 98,000 square
feet in the aggregate (such buildings known individually as Building I,
Building II and Building III and hereinafter collectively referred to as the
"Existing Facility"), (2) the demolition of Building I which contains
approximately 14,105 square feet of space, (3) the construction of a new
building to replace Building I and which will contain approximately 32,000
square feet of space (the "New Facility") (the Existing Facility and the New
Facility hereinafter collectively referred to as the "Facility"), (4) the
renovation of Building III and (5) the acquisition of and installation therein
and thereon of certain machinery and equipment (the "Equipment") (the Land, the
Facility and the Equipment being hereinafter collectively referred to as the
"Project Facility"), all of the foregoing to be occupied by Mechanical
Technology Incorporated (the "Company") and operated as a manufacturing
facility, a portion of which will be leased by the Company to Plug Power, LLC
and operated as a facility for the manufacture, research and development of
fuel cells for residential and automotive applications and related products and
any other related activities; (B) the financing of all or a portion of the
costs of the foregoing by the issuance of the Bonds; (C) the granting of
certain other "financial assistance" (within the meaning of Section 854(14) of

or such other person as may be designated by the Company and agreed upon by the
Agency. The Project Facility is to be sold by the Issuer to the Company
pursuant to the provisions of an installment sale agreement dated as of
December 1, 1998 (the "Installment Sale Agreement") by and between the Issuer
and the Company. 

The Bonds are issued under and are equally and ratably secured by the

Trust Revenues (as defined in the Indenture). 

In order to provide additional security for the Bonds, the Company has entered
into an irrevocable letter of credit and reimbursement agreement dated as of

in favor of the Trustee an irrevocable transferable direct pay letter of credit
(the "Letter of Credit"), issued in an amount equal to the aggregate principal
amount of the Bonds Outstanding, plus at least 210 days' interest on the Bonds,
computed at the Fixed Rate in effect, together with the Optional Redemption
Premium. Under the Letter of Credit, the Bank is obligated to pay to the
Trustee, upon presentation of a sight draft and required accompanying
documentation, the amount necessary to pay, the principal of, and interest on


the Bonds then due and payable (whether by mandatory redemption or by maturity
due to acceleration or otherwise). On each Bond Payment Date and immediately
upon (1) a declaration that all the Bonds have become due and payable by
acceleration, or (2) a mandatory redemption of all the Bonds Outstanding, the
Trustee shall present to the Bank a sight draft and required accompanying
documentation and draw upon the Letter of Credit for the principal amount, if
any and accrued interest then due on the Bonds. The Letter of Credit provides
that it shall expire on _____________ or earlier under certain circumstances.
The Company may provide for delivery to the Trustee of a Substitute Letter of
Credit or an Alternate Letter of Credit issued by another banking institution
as provided in the Installment Sale Agreement. 

As additional security for the payment of principal of and interest on the
Bonds, the Issuer has assigned to the Trustee all of the Issuer's rights and
remedies under the Installment Sale Agreement (except the Unassigned Rights, as
therein defined), including the right to receive installment purchase payments
and other amounts payable thereunder pursuant to a pledge and assignment dated
as of December 1, 1998 (the "Pledge and Assignment") from the Issuer to the
Trustee. Further security for the payment of principal of and interest on the
Bonds is provided by a guaranty dated as of December 1, 1998 (the "Guaranty")
from _______________ (the "Corporate Guarantor") to the Trustee. The Assignment
of Rents, the Pledge and Assignment and a memorandum relating to the
Installment Sale Agreement are to be recorded in the office of the County Clerk
of Albany County, New York. 

Reference is hereby made to the Indenture, the Installment Sale Agreement, the
Reimbursement Agreement, the Pledge and Assignment, the Guaranty and the Letter
of Credit, and to all amendments and supplements thereto, for a description of
the nature and extent of the security for the Bonds, the terms and conditions
upon which the Bonds are issued and secured and the rights, duties and
obligations of the Issuer, the Trustee, the Company, the Bank and the
Bondholders. Copies of such documents are on file in the Office of the Trustee.

THE BONDS ARE LIMITED OBLIGATIONS OF THE ISSUER PAYABLE SOLELY FROM PAYMENTS
MADE BY THE BANK UNDER THE LETTER OF CREDIT AND BY THE COMPANY UNDER THE
INSTALLMENT SALE AGREEMENT, MONEYS AND SECURITIES HELD BY THE TRUSTEE UNDER THE
INDENTURE, AND THE SECURITY PROVIDED BY THE PLEDGE AND ASSIGNMENT AND THE
