the Project Fund to pay Project Facility Costs actually incurred in connection
with the renovation of the Existing Facility and construction of the New
Facility and the cost of acquisition and installation of the Equipment in the
Project Facility (including Indirect Costs) if and to the extent such Project
Facility Costs are reflected in the Construction Budget as being funded by
proceeds of the Bonds. 

5.1	Reimbursement Agreement. The Company shall have an obligation to pay
all sums due under the Reimbursement Agreement and the other Bank Documents (as
well as any and all reasonable fees and expenses set forth therein). 

5.2	Advances. The Construction Budget reflects, by category and line items,
the purposes and the amounts for which funds to be advanced under this
Agreement and the Indenture are to be used. The Bank shall not be required to
consent to any disbursement for any category or line item more than the amount
specified therefor in the Construction Budget. 

5.3	Cost Overruns. If the Company becomes aware of any change in Project
Facility Costs which will increase a category or line item of Project Facility
Costs reflected on the Construction Budget (as the Construction Budget is
revised from time to time and approved by the Bank), the Company shall
immediately notify the Bank in writing and promptly submit to the Bank for its
approval a revised Construction Budget. No further Advances need be consented
to by the Bank unless and until the revised Construction Budget so submitted by

the Company is approved by the Bank, and the Bank reserves the right to approve
or disapprove any revised Construction Budget in its sole and absolute
discretion. If the Bank approves the revised Construction Budget, and such
revised Construction Budget reflects Project Costs to be funded by the Bank in
excess of the proceeds available in the Project Fund, the amount of such excess
shall be funded by the Company. 

5.4	Contingency Reserve. Any amount allocated as Contingency Reserve in the
Construction Budget is not intended to be disbursed and will only be disbursed
upon the prior approval of the Bank, which approval can be withheld for any
reason or for no reason. The disbursement of a portion of the Contingency
Reserve shall in no way prejudice the Bank from withholding its consent to
disbursement of any further portion of the Contingency Reserve. 

5.5	Stored Materials. Advances of Bond proceeds shall not be made for any
materials, furnishings or Equipment not yet incorporated into the Land or the
Facility (the "Stored Materials") without the prior written consent of the
Bank. Any disbursement for the cost of Stored Materials shall be contingent
upon the Bank's receiving satisfactory evidence that: 

(a)	The Stored Materials are components in a form ready for incorporation
into the Improvements; 

(b)	The Stored Materials are stored either at the Land, in a bonded
warehouse, at a site controlled by the Company, or at such other site as the

with the funds to be disbursed and all lien rights or claims of the supplier
have been released or will be released upon payment with disbursed funds; 

(d)	The Bank and the Trustee have or will have upon payment with disbursed
funds a perfected, first priority security interest in the Stored Materials;
and 

(e)	The Stored Materials are insured for an amount equal to their
replacement costs.

Costs approved by the Bank and theretofore paid or to be paid with the proceeds
of such Advance plus ninety (90%) percent of all costs for construction of
Improvements approved by the Bank and incurred by the Company through the date
of the Request for Disbursement for such Advance, less the aggregate amount of
any Advances previously made. It is further understood that the retainage
described above is intended to provide a contingency fund protecting the Bank
against failure of the Company to fulfill any obligations under the Bank
Documents, and that the Bank may charge amounts against such retainage in the
event the Bank is required or elects to expend its own funds to cure any Event
of Default. 

5.7	Quality of Work. No Advance shall be due unless all work done at the
date the Request for Disbursement for such Advance is submitted is done in a
good and workmanlike manner and without defects, but the Trustee, upon consent
by the Bank, may disburse all or part of any Advance before the sum shall
become due if the Bank believes it advisable to do so, and all such Advances or
parts thereof shall be deemed to have been made pursuant to this Agreement.

custodian for, all or a substantial part of its property; (6) by its making an
assignment for the benefit of, or entering into a composition with, its

(u)	any "default" or "event of default" as such term is defined therein

ARTICLE 9 

RIGHTS AND REMEDIES 

9.1	Remedies. Upon the occurrence of any Event of Default, the Bank may at
any time thereafter refuse to consent to further Advances and at its option,
and upon written notice to the Trustee, exercise any or all of the following
rights and remedies: 

(a)	The Bank may, in its sole discretion, deliver to the Trustee, with a
copy to the Agency and the Company, notice of such occurrence and upon
compliance with the Indenture, direct the Trustee to redeem the Bonds; and 



(b) The Bank may, in its sole discretion, by notice to the Trustee, the Agency
and the Company, declare all unpaid principal of and accrued interest due in
accordance with the Reimbursement Agreement, together with all other sums
payable under the Bank Documents, to be immediately due and payable, whereupon
same shall become and be immediately due and payable, anything in the
Reimbursement Agreement or other Bank Documents to the contrary
notwithstanding, and without presentation, protest or further demand or notice
of any kind, all of which are expressly hereby waived by the Company; provided,
however, that the Bank may consent to Advances by the Trustee thereafter
without thereby waiving the right to demand payment of the sums owing under the
Reimbursement Agreement, without being obligated to consent to any other or
further Advances, and without affecting the validity of or enforceability of
the Reimbursement Agreement or other Bank Documents. Notwithstanding and
without limiting the generality of the foregoing, upon the occurrence of an
Event of Default under paragraph (s) of Article 8, or if any event has occurred
which but for the passage of time, the giving of notice or both would
constitute an Event of Default, at the sole option of the Bank, all obligations
of the Trustee to make further Advances shall terminate, and all unpaid
principal of and accrued interest on the Bonds, together with all sums payable
under the Bank Documents, automatically shall become and be immediately so due
and payable, without any declaration or other act. 

(c)	At the discretion of the Bank and on behalf of the Trustee (but in its
on behalf in the event that the Trustee has drawn upon the Letter of Credit in
accordance with the Indenture), the Bank may cause the renovation of the
Existing Facility and construction of the New Facility to be completed and may
enter upon the Land and construct, equip and complete the renovation of the
Existing Facility and construction of the New Facility in accordance with the
Plans and Specifications, with such changes therein as the Bank may, from time
to time, and in its sole discretion, deem appropriate. 

In connection with any renovation or construction undertaken by the Bank
pursuant to the provisions of this subparagraph, the Bank may: 

(1)	use any funds of the Company, including any balance which may be held
by the Bank as security or in escrow, and any funds remaining unadvanced under
the Indenture; 

(2)	employ existing contractors, subcontractors, agents, architects,
engineers, and the like, or terminate the same and employ others; 

(3)	employ security watchmen to protect the Project Facility; 

(4)	make such additions, changes and corrections in the Plans and
Specifications as shall, in the judgment of the Bank, be necessary or
desirable; 

(5)	take over and use any and all Equipment contracted for or purchased by
the Company, if appropriate, or dispose of the same as the Bank sees fit; 

(6)	execute all applications and certificates on behalf of the Company
which may be required by any Governmental Authority or Requirement or contract
documents or agreements; 

(7)	pay, settle or compromise all existing or future bills and claims which
are or may be liens against the Project Facility, or may be necessary for the
completion of the Improvements or the clearance of title to the Project
Facility; 


(8)	enter into leases and occupancy agreements, and modify or amend
existing leases and occupancy agreements, all as the Bank shall deem to be
necessary or desirable; 

(9)	prosecute and defend all actions and proceedings in connection with the
construction of the Improvements or in any other way affecting the Project
Facility; 

(10)	enter into agreements or modify or amend existing agreements (including
the Bank Documents) with the Agency and the Trustee as the Bank, the Agency and
the Trustee in their absolute discretion deem necessary or desirable; and 

(11)	take such action hereunder, or refrain from acting hereunder, as the
Bank may, in its sole and absolute discretion, from time to time determine, and
without any limitation whatsoever, to carry out the intent of this
subparagraph. The Company shall be liable to the Bank for all costs paid or
incurred for the construction, completion and equipping of the Project
Facility, whether the same shall be paid or incurred pursuant to the provisions
of this subparagraph or otherwise, and all payments made or liabilities
incurred by the Bank hereunder of any kind whatsoever shall be deemed advances
made to the Company under this Agreement and shall be secured by the Mortgage
or the Indenture, and the other Bank Documents. 

To the extent that any costs so paid or incurred by the Bank, together with all
other Advances made by the Bank hereunder, exceed the Project Funds, such
excess costs shall be paid by the Company to the Bank on demand, with interest
thereon at the rate set forth at Section 2.2(a)(i) of the Reimbursement
Agreement, until paid; and the Company shall execute such notes or amendments
to the Reimbursement Agreement as may be requested by the Bank to evidence the
Company's obligation to pay such excess costs and until such notes or
amendments are so executed by the Company, the Company's obligation to pay such
excess costs shall be deemed to be evidenced by this Agreement and the
Reimbursement Agreement. In the event the Bank takes possession of the Project
Facility and assumes control of such construction as aforesaid, it shall not be
obligated to continue such construction longer than it shall see fit and may
thereafter, at any time, change any course of action undertaken by it or
abandon such construction and decline to make further payments for the account
of the Company whether or not the Project Facility shall have been completed.
For the purpose of this subparagraph, the construction, equipping and
completion of the Project Facility shall be deemed to include any action
necessary to cure any Event of Default by the Company under any of the terms
and provisions of any of the Bank Documents. 

(d)	the Bank may to the extent permitted by applicable law, at any time and
from time to time, without notice (any such notice being expressly waived),
without regard to the adequacy of any collateral, set off and apply any and all
deposits (general or specific, time or demand, provisional or final, regardless
of currency, maturity, or the branch of the Bank where the deposits are held)
at any time held or other sums credited by or due from the Bank to the Company
against any and all liabilities, direct or indirect, absolute or contingent,
due or to become due, now existing or hereafter arising of the Company to the
Bank. 

(e)	the Bank may exercise any or all of the rights and remedies set forth
in the Reimbursement Agreement or the Mortgage, or other Bank Documents, as
appropriate. 

9.2	Remedies Not in Conflict with the Indenture. In addition, and to the
extent not in conflict with the Indenture, the Company agrees to the following:

(a)	Power of Attorney. For the purposes of carrying out the provisions and
exercising the rights, powers and privileges granted by or referred to in this
Agreement, the Company hereby irrevocably constitutes and appoints the Bank its
true and lawful attorney-in-fact, with full power of substitution, to execute,
acknowledge and deliver any instruments and do and perform any acts which are
referred to in this Agreement, in the name and on behalf of the Company. The
power vested in such attorney-in-fact is, and shall be deemed to be, coupled
with an interest and irrevocable. 

(b)	Remedies Cumulative. Upon the occurrence of any Event of Default and
expiration of any cure period, the rights, powers and privileges provided in
this Article 9 and all other remedies available to the Bank under this
Agreement, the Reimbursement Agreement, or under any of the other Bank
Documents or at law or in equity may be exercised by the Bank at any time and
from time to time and shall not constitute a waiver of any of the Bank's other
rights or remedies thereunder, whether or not the Bonds shall be due and
payable, and whether or not the Bank shall have instituted any foreclosure
proceedings or other action for the enforcement of its rights under the
Reimbursement Agreement or other Bank Documents. 

(c)	Annulment of Defaults. An Event of Default shall not be deemed to be in
existence for any purpose of this Agreement, the Reimbursement Agreement or any
other Bank Document if the Bank shall have waived such Event of Default in
writing or stated in writing that the same has been cured to its reasonable
satisfaction, but no such waiver shall extend to or affect any subsequent Event
of Default or impair any of the rights of the Bank upon the occurrence thereof.

(d)	Waivers. The Company hereby waives to the extent not prohibited by
applicable law (a) all presentments, demands for payment or performance,
notices of nonperformance (except to the extent required by the provisions
hereof or of any other Bank Documents), protests and notices of dishonor, (b)
any requirement of diligence or promptness on the Bank's part in the
enforcement of its rights (but not fulfillment of its obligations) under the
provisions of this Agreement, the Reimbursement Agreement, or any other Bank
Document, and (c) any and all notices of every kind and description which may
be required to be given by any statute or rule of law and any defense of any
kind which the Company may now or hereafter have with respect to its liability
under this Agreement or under any other Bank Document. 

(e)	Course of Dealing, Etc. No course of dealing between the Company and
the Bank shall operate as a waiver of any of the Bank's rights under this
Agreement or any Bank Document. No delay or omission on the Bank's part in
exercising any right under this Agreement or any other Bank Document shall
operate as a waiver of such right or any other right hereunder. A waiver on any
one occasion shall not be construed as a bar to or waiver of any right or
remedy on any future occasion No waiver or consent shall be binding upon the
Bank unless it is in writing and signed by the Bank. The making of an Advance
hereunder during the existence of an Event of Default shall not constitute a
waiver thereof. 

ARTICLE 10 

GENERAL CONDITIONS 

The following conditions shall be applicable throughout the term of this
Agreement: 




10.1    Rights of Third Parties. All conditions of the obligations of the Bank
hereunder, including the obligation to consent to Advances, are imposed solely
and exclusively for the benefit of the Bank and its successors and assigns and
no other person shall have standing to require satisfaction of such conditions
in accordance with their terms or be entitled to assume that the Bank will make
Advances in the absence of strict compliance with any or all thereof and no
other person shall, under any circumstances, be deemed to be a beneficiary of
such conditions, any and all of which may be freely waived in whole or in part
by the Bank at any time if in its sole discretion it deems it desirable to do
so. In particular, the Bank makes no representations and assumes no obligations
as to third parties, including, but not limited to, the Agency or the holders
of the Bonds, concerning the quality of the construction by the Company of the
Improvements or the absence therefrom of defects. In this connection the
Company agrees to and shall indemnify the Trustee and the Bank from any
liability, claims or losses resulting from the disbursement of Advances or from
the condition of the Project Facility whether related to the quality of
construction or otherwise and whether arising during or after the termination

Bonds and any sums due under the Bank Documents and shall continue in full
force and effect so long as the possibility of such liability, claims or losses
exists. 

10.2	Limitation on Agency Liability; Indemnity. No provision or covenant
contained in this Agreement or any obligation herein or the breach thereof

under this Agreement in accordance with the provisions of the Installment Sale
Agreement. 

10.3	Relationship. The relationship between the Bank and the Company is
solely that of a lender and borrower, and nothing contained herein or in any of
the other Bank Documents shall in any manner be construed as making the parties
hereto partners, joint venturers or any other relationship other than lender
and borrower. 

10.4	Evidence of Satisfaction of Conditions. Any condition of this Agreement
which requires the submission of evidence of the existence or non-existence of
a specified fact or facts implies as a condition the existence or
non-existence, as the case may be, of such fact of facts and the Bank shall, at
all times, be free independently to establish to its satisfaction and in its
absolute discretion such existence or non-existence.

the Bank from bringing any suit, action or proceeding or exercising any rights
against any security and against the Company, and against any property of the
Company, in any other state. Initiating such suit, action or proceeding or
taking such action in any state shall in no event constitute a waiver of the

the rights and obligations of the Company and the Bank hereunder or the
submission herein by the Company to personal jurisdiction within the State of
New York. 

10.13	Amendments. Neither this Agreement nor any provision hereof may be
changed, waived, discharged or terminated orally, but only by instrument in
writing signed by the party against whom enforcement of the change, waiver,
discharge or termination is sought.

the Agency, if any, contained herein and in the other Bank Documents and any
other instrument or document executed in connection therewith or herewith, and
any other instrument or document supplemental thereto or hereto, shall be
deemed the obligations and agreements of the Agency, and not of any member,
officer, director, agent (other than the Company) or employee of the Agency in
his individual capacity, and the members, officers, directors, agents (other

than the Company) and employees of the Agency shall not be liable personally
hereon or thereon or be subject to any personal liability or accountability
based upon or in respect hereof or thereof or of any transaction contemplated

the Town of Colonie, New York shall be liable hereon or thereon, and, further,
such obligations and agreements shall not constitute or give rise to a general

the Agency payable solely from the revenues of the Agency derived and to be
derived from the sale or other disposition of the Project Facility (except for
revenues derived by the Agency with respect to the Unassigned Rights).

obligations of the Agency hereunder shall be sought or enforced against the
Agency unless (1) the party seeking such order or decree shall first have
requested the Agency in writing to take the action sought in such order or
decree of specific performance, and ten (10) days shall have elapsed from the
date of receipt of such request, and the Agency shall have refused to comply
with such request (or, if compliance therewith would reasonably be expected to
take longer than ten days, shall have failed to institute and diligently pursue
action to cause compliance with such request within such ten day period) or
failed to respond within such notice period, (2) if the Agency refuses to
comply with such request and the Agency's refusal to comply is based on its

such order or decree shall have placed in an account with the Agency an amount
or undertaking sufficient to cover such reasonable fees and expenses, and (3)
if the Agency refuses to comply with such request and the Agency's refusal to
comply is based on its reasonable expectation that it or any of its members,
officers, agents (other than the Company) or employees shall be subject to
potential liability, the party seeking such order or decree shall (A) agree to
indemnify, defend and hold harmless the Agency and its members, officers,
directors, agents (other than the Company) and employees against any liability

by the Agency, furnish to the Agency satisfactory security to protect the
Agency and its members, officers, directors, agents (other than the Company)
and employees against all liability expected to be incurred as a result of
compliance with such request. Any failure to provide the indemnity and/or
security required in this Section 10.14 shall not affect the full force and
effect of an Event of Default hereunder.
