regard to the adequacy of any security of the indebtedness or the solvency of
the Company, upon application to any court having jurisdiction, to the
appointment of a receiver of the rents, income and profits of the Mortgaged
Property.

managing the same, including reasonable compensation to Mortgagee, its agents
and counsel, and any charges of Mortgagee hereunder, and any taxes and other
charges prior to the lien of this Mortgage which Mortgagee may deem it wise to
pay. 

7.	PAYMENT OF TAXES. The Company will pay all taxes, assessments, sewer
rents or water rates or sums due under any payment in lieu of tax agreement
("Pilot Agreement") and in default thereof, Mortgagee may pay the same. In the
event that Mortgagee shall pay any such tax, assessment, sewer rent or water
rate, Mortgagee shall have the right, among other rights, to declare the amount
so paid with interest thereon immediately due and payable, and upon default of
the Company in paying any such amount with interest thereon, Mortgagee shall
have the right to foreclose for such amount subject to the continuing lien of
this Mortgage for the balance of the mortgage indebtedness not then due. 

In the event that the Company should fail to pay any sum the Company has agreed
to pay pursuant to this covenant for a period in excess of sixty (60) days
after the same is due and payable, in addition to any other remedies available
to the Mortgagee hereunder, the Mortgagee may, at its option, require that the
Company deposit with the Mortgagee, monthly, one-twelfth (1/12th) of the annual
charges for taxes and any other sums the Company is obligated to pay pursuant
to this covenant and the Company shall make such deposits with the Mortgagee.

money which together with the monthly installments aforementioned will be
sufficient to make payment of all sums required to be paid hereunder at least
thirty (30) days prior to the due date of such payments, it being understood
that the Mortgagee shall calculate the amount of such deposits and notify the
Company of the sum due. Should an Event of Default (hereinbelow defined) occur,

deposited or to the payment of any other sums secured by this Mortgage as the
Mortgagee sees fit.

mortgage at any time consolidated with this Mortgage, the Company agrees that
Mortgagee shall be entitled to a judgment directing the referee appointed in
the foreclosure proceeding to sell all of the parcels constituting the Premises
at one foreclosure sale, either as a group or separately and that the Company
expressly waives any right that it may now have or hereafter acquire to (i)
request or require that the parcels be sold separately or (ii) request, if

option of the Mortgagee. 

14.	BOOKS AND RECORDS.

Company shall keep and maintain at all times at the Company's addresses stated
in this Mortgage, or such other place as Mortgagee may approve in writing,
complete and accurate books of accounts and records adequate to reflect
correctly the results of the operation of the Mortgaged Property and copies of
all written contracts, leases and other instruments which affect the Mortgaged
Property. Such books, records, contracts, leases and other instruments shall be

of collection of any such taxes, so as to affect Mortgagee, this Mortgage, or
said indebtedness, Mortgagee shall have the right to give thirty (30) days'
written notice to the Company requiring the payment of said indebtedness. If
such notice be given, said indebtedness shall become due, payable and
collectible at the expiration of said thirty (30) days. 

16.	PROVISIONS REGARDING USE OF MORTGAGED PROPERTY. The Company warrants
and represents that: 

(a)	The Company is not responsible for any action or omission, and does not
know of any action or omission by any prior owner, that would cause the
Mortgaged Property to be subject to forfeiture pursuant to any law, rule or
regulation (a "Forfeiture"). 

(b)	The Mortgaged Property has not been acquired with any proceeds from a
transaction or an activity that would cause the Mortgaged Property to be
subject to Forfeiture. 

The Company covenants that the Company will not use, and will not permit any
third party to use, the Mortgaged Property or any portion thereof or interest
therein for any purpose or activity that would cause a Forfeiture thereof.

Mortgage, all sums paid by Mortgagee for the expense of any litigation to
prosecute and defend the rights and lien created by this Mortgage, including
reasonable counsel fees, costs and allowances, shall, together with interest
thereon be a lien on the Mortgaged Property and secured by this Mortgage and
shall be collectible in like manner as said indebtedness and shall be paid by
the Company on demand. 

18.	SECURITY INTEREST UNDER THE UNIFORM COMMERCIAL CODE. Mortgagee is
authorized to sign as the agent of the Company such agreement in addition to
this Mortgage as Mortgagee at any time may deem necessary or proper or require
to grant to Mortgagee a perfected security interest in the Chattels. The
Company hereby authorizes Mortgagee to file financing statements (as such term
is defined in said Uniform Commercial Code) with respect to the Chattels, at
any time, without the signature of the Company. The Company will, however, at
any time upon request of Mortgagee, sign such financing statements. the Company
will pay all filing fees for the filing of such financing statements and for
the refiling thereof at the times required, in the opinion of Mortgagee, by
said Uniform Commercial Code. If the lien of this Mortgage be subject to any
security agreement covering the Chattels, then in the event of any default
under this Mortgage, all the right, title and interest of the Company in and to
any and all of the Chattels is hereby assigned to Mortgagee, together with the
benefit of any deposits or payments now or hereafter made thereof by the
Company or the predecessors or successors in title of the Company in the
Mortgaged Property. 

19.	CONDEMNATION. Any and all awards heretofore and hereafter made to the
Company and all subsequent owners of the Mortgaged Property by any governmental
or other lawful authorities for the taking by eminent domain of the whole or
any part of the Mortgaged Property or any easement therein, including any
awards for any changes of grade of streets, are hereby assigned to Mortgagee,
who is hereby authorized to collect and receive the proceeds of any such awards
from such authorities, to give proper receipts and acquittances therefor and to
apply the same toward the payment of the amount owing on account of this
Mortgage and said indebtedness, notwithstanding the fact that the amount owing
thereon may not then be due and payable; and the Company hereby covenants and
agrees, upon request, to make, execute and deliver any and all assignments and
other instruments sufficient for the purpose of assigning the aforesaid awards
to Mortgagee free, clear and discharged of any and all encumbrances of any kind
or nature whatsoever. The Company shall continue to make all payments required
under the Bank Documents until any such award shall have been actually received
by Mortgagee and any reduction in said indebtedness resulting from the
application by Mortgagee of such award shall be deemed to take effect only on
the date of such receipt. 

Notwithstanding the foregoing, if any one or more of the portions of the
Mortgaged Property described in subparagraphs (a), (b) and (c) below shall be
damaged or taken through condemnation, either temporarily or permanently, then
the entire balance due under the Bank Documents shall, at the option of
Mortgagee, become immediately due and payable: 

(a)	Any portion or portions of the Improvements or the support or
foundation of any portion or portions of the Improvements; or 

(b)	Ten (10%) percent or more of any parking area which is not replaced; or

(c)	Any portion or portions of the Premises which, when so damaged or
taken, would result either in (i) an impairment of access to the Improvements
from the publicly dedicated rights of way now adjoining the Premises, or (ii)
the failure of the Improvements to comply with any building code, zoning or
other governmental laws or regulations, lease or other agreement to which the
Mortgaged Property is subject. 

The Company authorizes Mortgagee, at Mortgagee's option, as attorney in fact
for the Company, to commence, appear in and prosecute in the Company's or
Mortgagee's name, any action or proceeding relating to any condemnation or
other taking of the Mortgaged Property and to settle or compromise any claim in
connection with such condemnation or other taking.

amount above specified, with interest thereon at the rate set forth in the
Reimbursement Agreement and there are no defenses or offsets to this Mortgage
or to the said indebtedness.

portion of the Mortgaged Property without the prior written consent of
Mortgagee. Mortgagee is aware of and consents to existing leases.

Company be a corporation, or partnership interest, if the Company be a
partnership, or any membership interest, if the Company be a limited liability

assigns, be immediately due and payable without notice or demand unless the

time, to take action to recover any amounts of past due principal indebtedness
and interest thereon, or any installment of either, or any other sums required
to be paid under the covenants, terms and provisions of this Mortgage or the
Note, as the same become due, whether or not the principal indebtedness
secured, or any other sums secured by this Mortgage shall be due, and without
prejudice to the right of Mortgagee thereafter to bring an action of
foreclosure, or any other action, for default or defaults by the Company
existing at the time such earlier action was commenced. 

27.	ADDITIONAL ACTS AND DOCUMENTS. The Company covenants that it will do,
execute, acknowledge, deliver, file and/or record, or cause to be recorded
every and all such further acts, deeds, conveyances, advances, mortgages,
transfers and assurances, in law as Mortgagee shall require for the better
assuring, conveying, transferring, mortgaging, assigning and confirming unto
Mortgagee all and singular the Mortgaged Property.

Mortgagee shall be cumulative and supplementary to and not exclusive of any
other rights and remedies afforded the holder of this Mortgage and the Note.

the security described herein, or any person or entity liable for any
indebtedness secured hereby without in any way affecting the lien hereof upon
any part of the security not expressly released, and may agree with any party
obligated on said indebtedness or having any interest in the security described
herein to extend the time for payment of any part or all of the indebtedness
secured hereby. Such agreement shall not in any way release or impair the lien
hereof, but shall extend the lien hereof as against the title of all parties
having any interest in said security, which interest is subject to said lien,
and no such release or agreement shall release any person or entity obligated
to pay any indebtedness secured hereby. 

31.	WAIVERS. Any failure by Mortgagee to insist upon the strict performance
by the Company of any of the covenants, terms and provisions of this Mortgage
shall not be deemed to be a waiver of any of the covenants, terms and
provisions of this Mortgage, and Mortgagee, notwithstanding any such failure,
shall have the right thereafter to insist upon the strict performance by the
Company of any and all of the covenants, terms and provisions of this Mortgage
to be performed by the Company. Neither the Company nor any other person or
entity now or hereafter obligated for the payment of the whole or any part of
said indebtedness shall be relieved of such obligation by reason of (i) the
failure of Mortgagee to comply with any request of the Company, or of any other
person or entity so obligated, (ii) the failure of Mortgagee to take action to
foreclose this Mortgage or otherwise enforce any of the covenants, terms and
provisions of this Mortgage or the other Bank Documents, (iii) the release,
regardless of consideration, of the whole or any part of the security held for
payment of said indebtedness or (iv) any agreement or stipulation between any
subsequent owner or owners of the Mortgaged Property and Mortgagee modifying

Documents without first having obtained the consent of the Company or such
other person or entity. In the last mentioned event, the Company and all such
other persons or entities shall continue liable to make such payments according
to the terms and provisions of any such agreement or extension or modification
unless expressly released and discharged in writing by Mortgagee. Mortgagee may
release, regardless of consideration, any part of the security held for payment
of said indebtedness without, as to the remainder of the security, in any way
impairing or affecting the lien of this Mortgage or the priority of such lien
over any subordinate lien. Mortgagee may resort for the payment of said
indebtedness to any other security therefor held by Mortgagee in such order and
manner as Mortgagee may elect. 

32.	INTEREST ON ADVANCES. Wherever, under the provisions of this Mortgage
or by law, Mortgagee is entitled to interest on advances made or expenses
incurred, such interest shall be computed at a rate per annum which shall be
the Default Rate (as that term is defined in the Reimbursement Agreement). 

33.	MORTGAGEE NOT OBLIGATED. Nothing herein contained shall be construed as
making the payment of any insurance premiums, taxes or assessments obligatory
upon Mortgagee, although Mortgagee may pay same, or as making Mortgagee liable
in any way for loss, damage or injury, resulting from the non-payment of any
such insurance premiums, taxes or assessments. 

34.	LIEN LAW. The Company will, in compliance with Section 13 of the Lien
Law, receive the advances secured by this Mortgage and will hold the right to
receive such advances as a trust fund to be applied first for the purpose of
paying the cost of the improvement and will apply the same first to the payment

for any other purpose.

contamination of the Mortgaged Property with hazardous or toxic substances.

Mortgagee takes under this Mortgage shall be taken to protect Mortgagee's
security interest only; Mortgagee does not hereby intend to be involved in the
operations of the Company. 

(h)	Compliance Determinations. The Company acknowledges that any

insurance carrier and, consequently, the Company waives any and all right to
claim or recover against Mortgagee, its officers, employees, agents and
representatives, for loss of or damage to the Company, the Mortgaged Property,
the Company's property or the property of others under the Company's control
from any cause insured against or required to be insured against by the
provisions of this Mortgage. 

(d)	All sums payable by the Company hereunder shall be paid without notice
(except as may otherwise be provided herein), demand, counterclaim, set-off,
deduction or defense and without abatement, suspension, deferment, diminution
or reduction, and the obligations and liabilities of the Company hereunder
shall in no way be released, discharged or otherwise affected by reason of: (i)
any damage to or destruction of or any condemnation or similar taking of the
Mortgaged Property or any part thereof; (ii) any restriction or prevention of
or interference with any use of the Mortgaged Property or any part thereof;
(iii) any title defect or encumbrance or any eviction from the Premises or the

have, against Mortgagee; (vi) any default or failure on the part of Mortgagee
to perform or comply with any of the terms hereof or of any other agreement

interpretation, collection or enforcement thereof, or the relationship between
the Company, the Agency and Mortgagee as borrower and lender, or any other
claim or dispute howsoever arising between the Company and Mortgagee. 

47.	BUILDING LOAN CONTRACT. This Mortgage is executed in conjunction with a
Building Loan Contract which is intended to be filed on even date with the
recording of this Mortgage and any breach, violation or default in the
performance of any covenant required to be performed under the Building Loan

48.	NON RECOURSE AS TO ISSUER. _)	

(a) The obligations and agreements of the Agency, if any, contained herein and
in the other Bank Documents and any other instrument or document executed in

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 hereby or thereby. 

(b)	The obligations and agreements of the Agency contained herein and
therein shall not constitute or give rise to an obligation of the State of New
York or the Town of Colonie, New York, and neither the State of New York nor
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
obligation of the Agency, but rather shall constitute limited obligations of
the Agency payable solely from the revenues of the Agency derived and to be
derived from the sale or other disposition of the Mortgaged Property (except
for revenues derived by the Agency with respect to the Unassigned Rights). 

(c)	No order or decree of specific performance with respect to any of the
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
reasonable expectation that it will incur fees and expenses, the party seeking
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
incurred as a result of its compliance with such demand, and (B) if requested
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 48 shall not affect the full force and effect
of an Event of Default hereunder.
