ARTICLE 1:  AGREEMENT

The Landlord hereby leases to and the Tenant hereby leases from the Landlord
the premises described herein according to the terms and conditions of this
lease.

ARTICLE 2:  PREMISES

The premises consists of approximately 20,700 useable square feet of space in
the building known as 325 Washington Avenue Extension, Albany, NY 12205. See
Exhibit A.


ARTICLE 3:  TERM

3.1	The Term of this lease shall be 10 years commencing on the 1st day of
December, 1999 and expiring on the 30th day of November, 2009.

3.2	The Landlord will be deemed to have delivered possession of the
premises to the Tenant on the date set forth in the Workletter (Exhibit B) upon
substantial completion of the work set forth in the Workletter. Substantial
completion means that the Tenant can use the premises for their intended
purposes without material interference to its ordinary business activities and
a certificate of occupancy has been granted. The premises will be completed 30
days after occupancy unless otherwise agreed by Tenant and Landlord not to be
unreasonably withheld.

3.3	In the event that space shall become available which is contiguous to
the said 20,700 SF occupied by Tenant, Landlord shall first offer this to
Tenant before actively attempting to lease at prevailing rates.


ARTICLE 4:  BASE RENT

4.1	The Tenant shall pay monthly rent to the Landlord according to the
following schedule:

$25,012.50   Years 1-5
$26,306.25   Years 6-10

Monthly rent will be paid in advance on or before the first day of each
calendar month of the term. If the lease commencement date is on a day other
than the first day of a calendar month, then monthly rent will be appropriately
prorated by Landlord based on the actual number of calendar days in such month.
Monthly rent will be paid to Landlord, without written notice or demand, and
without deduction or offset (other than deductions or offsets expressly
permitted herein), in lawful money of the United States of America at
Landlord's address, or to such other address as Landlord may from time to time
designate in writing.

ARTICLE 5:  ADDITIONAL RENT - OPERATING EXPENSES

5.1	Utility Services. The Tenant shall pay directly to the Utility Company
and shall solely be liable for the cost of natural gas, or other fuel,
electricity, communication, or any other service used in or supplied to the
demised premises throughout the term of this lease or any extension thereto.

5.2	The Tenant's proportionate share is 78.80% and is calculated as
follows: Tenant's useable square footage 20,700, divided by the total useable
square footage in the building 26,268.

5.3	The Tenant shall pay as additional rent within 30 days of receipt of
the Landlord's invoice and supporting detail the Tenant's proportionate share
of any increase in real and personal property taxes and assessments and any tax
or assessments levied in lieu of, or in addition to, real property taxes above
those incurred by the Landlord during the initial year of the lease (the base
year: December 1, 1999 - November 30, 2000). The base year amount is determined
by multiplying the tax rate in effect during the base year times the assessment
for the parcel at full assessment. If there is a tax abatement in effect then
this amount will be calculated as if there were no abatement. Tenant reserves
the right to protest the taxes if Landlord chooses not to.


ARTICLE 6:  USE OF PREMISES

laws and ordinances including general office purposes, assembly, limited

6.2	Tenant is engaged in assembly, limited machine shop, laboratory,
shipping/receiving, office and research and will continue to conduct such
business as it is currently conducted. Tenant will control its employees,
agents and invitees in such a manner as to not create a nuisance or interfere
with any other tenant in the building or park or the Landlord in its operation
of the building or park.


ARTICLE 7:  ASSIGNMENT AND SUBLETTING

7.1	The Tenant shall not assign this lease, nor sublease, nor permit the
premises or any part of the premises to be used or occupied by others without
the prior written consent of the Landlord which shall not be unreasonably
withheld or delayed. Landlord shall have ten (10) business days from receipt of
Tenant's request to deny its consent or it will be deemed to consent. If
Landlord denies consent it must explain the reasons for denial.

7.2	If the Landlord consents to a proposed assignment or sublease, then the
Landlord will have the right to require the Tenant to pay to Landlord (a) any

rent or other consideration paid to Tenant by any proposed transferee that is
in excess of the rent allocable to the transferred space then being paid by
Tenant to the Landlord pursuant to this lease; and (b) any other profit or gain
(after deducting any necessary expenses incurred) realized by Tenant from any
such sublease or assignment.

7.3	The Landlord consents to an assignment of this lease or sublease of all
or part of the premises to a wholly-owned subsidiary of the Tenant or the
parent of the Tenant or to any corporation into or with which the Tenant may be
merged or consolidated or to any purchaser of the stock or assets of the
Tenant; provided that in the case of a sublease the Tenant promptly provides
the Landlord with a fully executed copy of such assignment or sublease and that
the Tenant is not released from liability under the lease.


ARTICLE 8:  COMPLIANCE WITH LAWS

8.1	At its sole cost and expense, Tenant will promptly comply with all
laws, statutes, ordinances, and governmental rules, regulations, or
requirements now in force or in force after the lease date and with the

hereafter in effect (collectively, "hazardous materials laws").

8.3	Tenant will not do or permit to be done anything upon the premises or
the project which would (a) jeopardize or be in conflict with fire insurance
policies covering the project and fixtures and property in the project in
existence as of August 18, 1999; (b) increase the rate of fire insurance
applicable to the project to an amount higher than it otherwise would be for
general office use of the project; or (c) subject Landlord to any liability or
responsibility for injury to any person or persons or to property by reason of
any business or operation being carried on upon the premises.

delivered to Tenant, reasonable wear and tear excluded. All damage or injury to
the premises, the building or the project, that is caused by Tenant, its
agents, employees, or invitees may be repaired, restored, or replaced by
Landlord, at the expense of Tenant.

ARTICLE 10:  ALTERATIONS

During the term, Tenant will not make or allow to be made any alterations,
additions, or improvements to or of the premises or any part of the premises,

Landlord, will be made in a good and workmanlike manner and will be performed
by contractors approved by Landlord and subject to conditions specified by the
Landlord.


ARTICLE 11:  RULES AND REGULATIONS

The Tenant and its employees, agents, licensees, and visitors will at all times
observe faithfully, and comply strictly with, the rules and regulations set
forth in Exhibit D, however such rules and regulations shall not be in conflict
with stated use in Article 6. Landlord may from time to time reasonably amend,
delete, or modify existing rules and regulations, or adopt reasonable new rules
and regulations for the use, safety, cleanliness, and care of the premises, the
building, and the project, and the comfort, quiet, and convenience of occupants
of the building and/or the project.

ARTICLE 12:  QUIET ENJOYMENT

Landlord covenants and agrees that so long as Tenant pays the rent and observes
and performs all the terms and conditions of this lease, the Tenant may
peaceably and quietly enjoy the premises subject to the terms and conditions of
this lease, and Tenant's possession will not be disturbed by the Landlord or
anyone claiming by, through, or under the Landlord.

ARTICLE 13:  SUBORDINATION AND NON-DISTURBANCE

13.1 This lease and the Tenant's rights under this lease are subject and
subordinate to any ground or underlying lease, mortgage, indenture, deed of
trust, or other lien encumbrance (each a "superior lien"), together with any
renewals, extensions, modifications, consolidations, and replacements of such
superior lien, now or after the date placed, charged or enforced against the
land, the building, or all or any portion of the project (except to the extent
any such instrument expressly provides that this lease is superior to such
instrument). This provision will be self- operative and no further instrument
of subordination will be required in order to effect it. In the event a current
or future mortgage holder requires a separate subordination agreement to be
executed, the Tenant will, upon Landlord's request, execute same promptly.

13.2	Tenant will, upon request of any person or party succeeding to the
interest of Landlord, automatically become the Tenant of and attorn to such
successor in interest without change in the terms or provisions of this lease.

13.3	As long as the Tenant is in compliance with the terms of this lease and
is not in default in the performance of its obligations under the lease, the
Tenant's use and possession of the premises shall not be disturbed nor will the
lease be terminated by any person or party succeeding to the Landlord's
interest.


ARTICLE 14:  END OF TERM

At the end of this lease, Tenant will promptly quit and surrender the premises
in good order and repair, ordinary wear and tear excepted. The Tenant will
remove the Tenant's trade fixtures, equipment, and furniture and will fully
repair any damage occasioned by the removal of any trade fixtures, equipment or
furniture. All trade fixtures, equipment, furniture, inventory and effects, on

the premises after the end of the term will be deemed conclusively to have been
abandoned and may be appropriated, sold, stored, destroyed, or otherwise
disposed of by Landlord without written notice to Tenant or any other person
and without obligation to account for them. Tenant will pay Landlord for all
expenses incurred in connection with the removal of such property, including
but not limited to the cost of repairing any damage to the building or premises
caused by the removal of such property. Tenant's obligation to observe and
perform this covenant will survive the expiration or other termination of this
lease.

the Landlord for the cost of the material (wax) and labor in excess of the cost
of the material for normal maintenance of VCT.


ARTICLE 17:  COMMON AREAS

As used in this lease, the term "common areas" means, without limitation, the
hallways, entryways, stairs, elevators, driveways, walkways, terraces, docks,

license for the term to use the common areas in common with others entitled to
use the common areas, subject to the terms and conditions of this lease.
Without advance written notice to Tenant, and without any liability to Tenant

Tenant's substantial benefit and enjoyment of the premises, Landlord will have
the right to:

(a)	Temporarily close any of the common areas for maintenance, alteration,
or improvement purposes; and

(b)	Change the size, use, shape or nature of any such common areas.


ARTICLE 18:  PARKING

Tenant will be entitled to use the parking spaces around the building or in the
project in common with other Tenants during the term subject to the rules and
regulations set forth in Exhibit D, and any amendments or additions to them.
The parking spaces will be unassigned, nonreserved, and nondesignated. The
Tenant uses the parking spaces at its own risk, and the Landlord will not be

accessories to any such vehicle, or any property left in any of the parking
areas. Tenant shall be entitled to at least sixty (60) spaces but no more than
eighty (80) spaces for Tenant's use on a regular basis.

ARTICLE 19:  ENTRY BY LANDLORD

ARTICLE 20:  INSURANCE

20.1	Landlord's Insurance. At all times during the term, Landlord will carry
and maintain:

(a)	Fire and extended coverage insurance covering the building, the
project, its equipment, common area furnishings, and leasehold improvements in
the premises;
(b)	Bodily injury and property damage insurance; and
(c)	Such other insurance as Landlord reasonably determines from time to
time.

These insurance coverages and amounts will be reasonably determined by

Landlord, based on coverages carried by prudent owners of comparable buildings
in the vicinity of the project. A copy of the Landlord's insurance policies
will be provided to the Tenant upon written request.

20.2	Tenant's Insurance. At all times during the term, Tenant will carry and
maintain, at Tenant's expense, the following insurance, in the amounts
specified below or such other amounts as Landlord may from time to time
reasonably request, with insurance companies and on forms satisfactory to

(a)	Bodily injury and property damage liability insurance, with a combined
single occurrence limit of not less than $3,000,000. All such insurance will be
equivalent to coverage offered by a commercial general liability form,

liabilities under the worker's compensation laws of the State of New York,

20.3	Certificate of insurance, naming the Landlord as additional insured,
will be delivered to the Landlord prior to the Tenant's occupancy of the
premises. All commercial general liability or comparable policies maintained by
Tenant will name Landlord as additional insured. All commercial general
liability and property policies maintained by Tenant will be written as primary
policies, not contributing with and not supplemental to the coverage that the
Landlord may carry. A copy of the Tenant's insurance policies will be provided
to the Landlord upon written request.

20.4	Waiver of Subrogation. The Landlord and Tenant each waive any and all
rights to recover against the other or against the officers, directors,
shareholders, partners, employees, agents, customers, invitees, or business
visitors of such other party, for any loss or damage to such waiving party
arising from any cause covered by any property insurance required to be carried
by such party pursuant to this Article 20 or any other property insurance
actually carried by such party to the extent of the limits of such party.
Landlord and Tenant from time to time will cause their respective insurers to
issue appropriate waiver of subrogation rights endorsements to all property
insurance policies carried in connection with the project or the premises or
the contents of the project or the premises.

ARTICLE 21:  INDEMNIFICATION

21.1	Except for any injury or damage to persons or property on the premises
that is caused by or results from the negligence or deliberate act of Landlord,
its employees, or agents, Tenant will not hold Landlord, its employees, or
agents liable for, and Tenant will indemnify and hold harmless Landlord, its
employees, and agents from and against, any and all demands, claims, causes of
action, fines, penalties, damages (including consequential damages),
liabilities, judgements, and expenses (including without limitation reasonable
attorneys' fees) incurred in connection with or arising from:

(a)	the use or occupancy or manner of use or occupancy of the premises by
Tenant or any person claiming under Tenant;


(b)     any activity, work, or thing done or permitted by Tenant in or about
the premises, the building, or the project;
(c)	any breach by Tenant or its employees, agents, contractors, or invitees
of this lease; and
(d)	any injury or damage to the person, property, or business of Tenant,
its employees, agents, contractors, or invitees entering upon the premises
under the express or implied invitation of Tenant.

21.2	If any action or proceeding is brought against Landlord, its employees,
or agents by reason of any such claim for which Tenant has indemnified
Landlord, Tenant, upon written notice from Landlord, will defend the same at
Tenant's expense.


ARTICLE 22:  DAMAGE AND DESTRUCTION

22.1	If the premises or the building are damaged by fire or other insured
casualty, Landlord will give Tenant written notice of the time which will be
needed to repair such damage, as determined by Landlord in its reasonable
discretion, and the election (if any) which Landlord has made according to this
Article 22. Such notice will be given before the 10th day (the "notice date")
after the fire or other insured casualty.

22.2	If the premises or the building are damaged by fire or other insured
casualty to an extent which may be repaired within 30 days after the notice
date, as reasonably determined by Landlord, Landlord will promptly begin to
repair the damage after the notice date and will diligently pursue the
completion of such repair. In that event this lease will continue in full force
and effect except that monthly rent will be abated on a pro rata basis from the
date of the damage until the date of the completion of such repairs (the
"repair period") based on the proportion of the rentable area of the premises
Tenant is unable to use during the repair period.

22.3	If the premises or the building are damaged by fire or other insured
casualty to an extent that may not be repaired within 30 days after the notice
date, as reasonably determined by Landlord, then (1) Landlord may cancel this
lease as of the date of such damage by written notice given to Tenant on or
before the notice date or (2) Tenant may cancel this lease as of the date of
such damage by written notice given to Landlord within 30 days after the notice
date. If neither Landlord nor Tenant so elects to cancel this lease, Landlord
will diligently proceed to repair the building and premises and monthly rent
will be abated on a pro rata basis during the repair period based on the
proportion of the rentable area of the premises Tenant is unable to use during
the repair period.

22.4	Notwithstanding the provisions of Subparagraphs 22.1, 22.2, and 22.3
above, if the premises or the building are damaged by uninsured casualty, or if
the proceeds of insurance are insufficient to pay for the repair of any damage
to the premises or the building, Landlord will have the option to repair such
damage or cancel this lease as of the date of such casualty by written notice
to Tenant on or before the notice date.

22.5	If any such damage by fire or other casualty is the result of the
willful conduct or gross negligence of Tenant, its agents, contractors,
employees or invitees, there will be no abatement of monthly rent as otherwise
provided for in this Article 22. Tenant will have no rights to terminate this
lease on account of any damage to the premises, the building, or the project,
except as set forth in this lease.


ARTICLE 23:  EMINENT DOMAIN

Landlord must notify Tenant of any actions, intentions or plans of any person
to take all or part of the premises by eminent domain within 10 days of
Landlord's knowledge of such action, intention or plan ("Eminent Domain
Notice").

If all or any of the premises may be taken by exercise of the power of eminent
domain (or conveyed by Landlord in lieu of such exercise), Tenant may within 60
days of such Eminent Domain Notice notify Landlord of its intention to
terminate this lease. If all the premises are to be taken by eminent domain,
Tenant must terminate the lease effective as of a date (the "termination date")
which is the earlier of the date upon which the condemning authority takes
possession of the premises or the date on which title to the premises is vested
in the condemning authority. If less than all of the premises are taken by
eminent domain and Tenant elects not to terminate the lease, the monthly rent
will be abated in the proportion of the rentable area of the premises so taken
to the rentable area of the premises immediately before such taking, and
tenant's share will be appropriately recalculated. If 25% or more of the
building or the project is so taken, Landlord may cancel this lease by written
notice to Tenant given as of 120 days after the Eminent Domain Notice Date. In
the event of any such taking, the entire award will be paid to Landlord and
Tenant will have no right or claim to any part of such award; however, Tenant
will have the right to assert a claim against the condemning authority in a
separate action, so long as Landlord's award is not otherwise reduced, for
Tenant's moving expenses and leasehold improvements owned by Tenant.


ARTICLE 24:  DEFAULT

24.1	Events of Default. The following events are referred to, collectively,
as "events of default" or, individually, as an "event of default":

(a)	Tenant defaults in the due and punctual payment of rent, and such
default continues for 10 days after written notice from Landlord; however,
Tenant will not be entitled to more than 2 written notices for monetary
defaults during any 12 month period, and if after such written notice any rent
is not paid when due, an event of default will be considered to have occurred
without further notice;
(b)	This lease or the premises or any part of the premises are taken upon
execution or by other process of law directed against Tenant, or are taken upon
or subject to any attachment by any creditor of Tenant or claimant against
Tenant, and said attachment is not discharged or disposed of within 30 days
after its levy;
(c)	Tenant files a petition in bankruptcy or insolvency or for
reorganization or arrangement under the bankruptcy laws of the United States or
under any insolvency act of any state, or admits the material allegations of
any such petition by answer or otherwise, or is dissolved or makes an
assignment for the benefit of creditors;
(d)	Involuntary proceedings under any such bankruptcy law or insolvency act
or for the dissolution of Tenant are instituted against Tenant, or a receiver
or trustee is appointed for all or substantially all of the property of Tenant,
and such proceeding is not dismissed or such receivership or trusteeship
vacated within 60 days after such institution or appointment;
(e)	Tenant breaches any of the other agreements, terms, covenants, or
conditions that this lease requires Tenant to perform, and such breach
continues for a period of 30 days after written notice from Landlord to Tenant
or, if such breach cannot be cured reasonably within such 30 day period, if
Tenant fails to diligently commence to cure such breach within 30 days after

written notice from Landlord and to complete such cure within a reasonable time
thereafter.

24.2	Landlord's Remedies. If any one or more events of default set forth in
Section 24.1 occurs then Landlord has the right, at its election:

(a)	To give Tenant written notice of Landlord's intention to terminate this
lease on the earliest date permitted by law or on any later date specified in
such notice, in which case Tenant's right to possession of the premises will
cease and this lease will be terminated, except as to Tenant's liability;
(b)	Without further demand or notice, to reenter and take possession of the
premises or any part of the premises, repossess the same, expel Tenant and
those claiming through or under Tenant, and remove the effects of both or
either, using such force for such purposes as may be necessary without
prejudice to any remedies for arrears of monthly rent or other amounts payable
under this lease; or
(c)	Without further demand or notice to cure any event of default and to
charge Tenant for the cost of effecting such cure, including without limitation
reasonable attorneys' fees.

24.3	Waiver of Redemption. The Tenant waives any right of redemption arising
as a result of the Landlord's exercise of its remedies under this Article 24.

24.4	Notice of Landlord's Default. In the event of any default in the
obligation of the Landlord under this lease, Tenant will deliver to Landlord
written notice listing the reasons for Landlord's default and Landlord will
have 30 days following receipt of such notice to cure such default or, in the
event the default cannot reasonably be cured within a 30 day period, to
commence action and proceed diligently to cure such default. A copy of such
notice to Landlord will be sent to any holder of a mortgage or other
encumbrance on the building or project of which Tenant has been notified in
writing, any such holder will also have the same time periods to cure such
default. If any such default remains uncured Tenant has the right at it's
election to cure such default at Landlord's expense with prior written
notification given to Landlord.

24.5	Self Help. If either party defaults, the other party may, without being
obligated and without waiving the default, cure the default. The defaulting
party shall pay upon demand, all costs, expenses, and disbursements incurred by
the non-defaulting party to cure the default.


ARTICLE 25:  MISCELLANEOUS

25.1	Late Charges. A late charge of 5% shall be assessed to any payment of
rent or additional rent not made within 10 days of the due date and shall be
considered additional rent. Interest on amounts more than 10 days past due
shall accrue and be payable at the rate of 1% per month.

25.2	No Waiver. The waiver by Landlord of any agreement, condition, or
provision contained in this lease will not be deemed to be a waiver of any
subsequent breach of the same or any other agreement, condition, or provision
contained in this lease, nor will any custom or practice that may grow up
between the parties in the administration of the terms of this lease be
construed to waive or to lessen the right of Landlord to insist upon the
performance by Tenant in strict accordance with the terms of this lease. The
subsequent acceptance of rent by Landlord will not be deemed to be a waiver of
any preceding breach by Tenant or any agreement, condition, or provision of


this lease, other than the failure of Tenant to pay the particular rent so
accepted, regardless of Landlord's knowledge of such preceding breach at the
time of acceptance of such rent.

25.3	Estoppel Certificates. At any time and from time to time but within 10
