holder provided in the Tenant's notice to Landlord. The holders of any Permitted
Mortgage shall have a period of thirty (30) days from the giving of the notice
of termination within which to cure the default of the Tenant in the pursuit of
completion of the construction of the Facility. If the default of the pursuit of
completion of construction cannot be cured by the holders of the Permitted
Mortgage within such thirty (30) day period, the holders shall have an
additional period of ninety (90) days within which to cure the default, provided
the holders promptly commence and diligently pursue the curing of the default.
The documents constituting the Plans will be attached as Exhibit C and made a
part of this Lease.

     Section 5.02.  Completion of Construction. Tenant shall, at its sole cost

          (b) shall comply with all requirements of public authorities described
in Article 12 applicable to the Work;

          (c) shall have received Landlord's prior written approval of all
architects, engineers and the general contractor to be engaged in the
construction of the Facility, which approval shall not be unreasonably withheld;

                                      -4-

the Plans, in a good and workmanlike manner and of first-class quality, and in
accordance with all the provisions of this Lease;

          (e) shall pay all proper accounts for work done or materials furnished
under all contracts which it has entered into relating to the Work, provided,
however, that Tenant may retain any amounts which Tenant's architect has not
certified to be due, or which are properly and reasonably retained to secure the
performance of any work or the correction of any defect or which, in the opinion
of the Tenant's architect, are reasonably retained in anticipation of damages
arising from any contractor's default, or which are required to be retained
under the provisions of the New York Lien Law;

          (f) Tenant shall require performance and payment bonds to be furnished
by the general contractor and each major subcontractor of the Work naming
Landlord as co-obligee of the bonds in an amount equal to the total cost of the
construction, acquisition and installation of the Facility, which is presently
estimated to be $73,100,000, unless the requirement of a bond shall have been
waived in writing by Landlord. If the holders of a Permitted Mortgage shall not
require performance and payment bonds for the total cost of the Facility, the
contractors may provide performance and payment bonds for less than the total
cost of the Facility, but not less than eighty (80%) percent of the total cost
of the Facility, provided guarantees of completion and performance for the
balance of the cost of the Facility shall be provided by entities, and in form,
reasonably acceptable to Landlord;

          (g) shall bear all costs incurred in the relocation, in a manner
reasonably satisfactory to Landlord, of all utilities and access servicing the
Existing Plant and the Landlord's

                                      -5-

opinion of licensed architects or engineers employed by Tenant or by Landlord,
or in such other form as Landlord reasonably may require, that:

          (a) the Facility shall have been completed in all respects in a good
and workmanlike manner and of first-class quality in accordance with the Plans;

          (b) The Facility and each of its components, including, all machinery,
equipment, apparatus and lines, are operating in accordance with the Plans, are
available for use by Tenant and are capable of delivery of steam to the Landlord
to the interconnection points, in the Volumes and meeting the specifications
required by the Steam Contract;

          (c) all building codes and other regulations and all requirements of
public authorities described in Article 12 have been complied with;

          (d) all permits and permanent unconditional certificates of occupancy
which are required have been obtained;

          (e) all approvals which are required for the operation of the Facility
and Tenant's performance of the Steam Contract have been obtained;

          (f) the contract with the Contractor for the operation of the
Facility, as provided in Section 1.02 of the Steam Contact, shall be in full
force and effect and the Contractor shall have commenced the performance of its
duties as operator of the Facility;

          (g) all parking areas are ready for use; and

                                      -6-

are clean and all surplus building material and rubbish removed from the
Premises.

          Section 5.05.  Assignments to Landlord. All contracts entered into by
          ------------   -----------------------
Tenant for the construction, installation and operation of the Facility shall be
assignable, at Landlord's option, to Landlord or its designee, upon Tenant's
failure to perform any of its obligations under this Article, subject, however,
to the requirements of all Consents and Agreements and any assignments which may
be required by the holder of a Permitted Mortgage as defined in Article 23.

     Section 5.06.  Fuel Transmission Line Easement. Landlord shall, without
     ------------   -------------------------------
expense to Tenant, provide an easement for a transmission line for natural gas
and/or propane over the land owned by Landlord between Jamesville Avenue and
East Colvin Street and proceeding northerly from East Colvin Street along the
easterly boundary of Comstock Avenue to the northerly boundary of 1601 East
Colvin Street and along the easterly boundary of the 200 block of Fineview Place
within the City of Syracuse, New York, provided, however, that such easement
shall be restricted to the transmission only of fuel for the operation of the
Facility and the Existing Plant. The location of the easement shall be mutually
determined by Landlord and Tenant. The easement shall terminate upon the
expiration or sooner termination of this Lease and shall be in such form and
upon such other terms and conditions as shall be acceptable to Landlord acting
reasonably.

prior written notice to the Landlord, to contest by appropriate legal
proceedings ("the proceedings") diligently conducted in good faith, in the name

Tenant, at its own cost and expense, within 30 days after the filing of the
lien, shall discharge it of record or post a bond reasonably satisfactory to

within 30 days after its filing, Landlord, in addition to any other right or
remedy it may have, and without waiving its right to declare a default, may
discharge the lien of record or post a bond to

                                      -16-

assure its discharge. Any amounts paid by Landlord in the discharge or bonding

making any necessary repairs or performing any other work that may be necessary
because of Tenant's failure to make repairs or perform other work after written
notice from Landlord, or at any time without notice in case of emergency.
Landlord's right of entry shall not imply any duty on its part to perform any
repairs or other work and Landlord's performance of any repairs or work shall
not constitute a waiver of any default of Tenant. Any such inspection shall be
conducted at Landlord's sole risk and expense. In

                                      -17-

     -------------

          (a) Tenant, without the prior written consent of Landlord, which shall
not unreasonably be withheld, shall not assign this Lease or sublet the whole or
any part of the Premises or the Facility, provided, however, that Tenant may
assign this Lease without the prior written consent of Landlord (i) to any
corporation, partnership or other entity controlling, controlled by, or under
common control with the Tenant or (ii) to the holders of a Permitted Mortgage,
defined in Article 23, for collateral security purposes only.  For purposes of

encumbrance, whether voluntary or involuntary or by operation of law, of more

families. Any attempted assignment or subletting in violation of this Section
shall be null and void.

          (b) Any assignment or subletting permitted by Landlord shall be upon

conditions as Landlord at the time of permission reasonably may require:

     notice from Landlord of any default under this Lease; and

              (vi)   Landlord's consent to any assignment or sublease shall not

     requirement of its consent, to any subsequent assignment or sublease.

          (c)        Except as otherwise expressly permitted by this Lease,
Tenant shall not delegate any of its obligations nor assign any of its rights
under this Lease separate from any permitted assignment.

surrender and deliver to Landlord the possession and use of the Premises and the
Facility, without delay, in good order, condition and repair, except for
reasonable wear and tear after the last necessary repair, replacement,
restoration or renewal made by Tenant, and free and clear of all liens,
encumbrances and charges, without any payment or allowance by Landlord on
account of any improvements on the Premises, and all rights of Tenant under this
Lease and in the Facility, shall terminate.  Notwithstanding the expiration or
termination of this Lease, Tenant shall remain liable to Landlord for any loss
or damage suffered by Landlord because of any default of Tenant.  Upon
surrender, Tenant shall assign to Landlord all operating agreements and other
agreements and rights, including any easements or rights-of-way, relating to the
operation or use of the Premises or the Facility, or Tenant's interest in them,
as Landlord may request, including the full and unencumbered use of any land
owned, leased or licensed by Tenant for the purpose of providing additional
parking, traffic, or other service facilities for use in connection with the
Premises or the Facility but excluding any properties, agreements, easements or
rights of way for the use or operation of, and rights of ownership or use with
respect to, pipelines, conduits, loading and storage facilities or other
properties, goods or equipment not regularly situated on the Premises or on the
easement referred to in Section 5.06 or on other easements located north of the
southerly commencement point of such easement. Notwithstanding the foregoing,
the rights to be so assigned shall include, but shall not be limited to, the
right to obtain transportation of natural gas to the Premises through any
natural gas pipeline constructed by or for Tenant for purposes of

                                      -21-
<PAGE>

providing transportation of natural gas from either an interstate or intrastate
transporter of natural gas or a local distribution company to the Facility (a
"Project Pipeline") to the extent of the maximum daily quantities of natural gas
which (i) are then required for operation of the Facility and (ii) were, at any
time within 24 months preceding the last operation of the Facility prior to the
expiration or earlier termination of this Lease, transported through a Project
Pipeline. The right described in the preceding sentence shall continue (x) for
any remainder of the term of this Lease as originally fixed by Section 3.01 (the
"Term"), on the terms and at the rates that would have been applicable to tenant
if this Lease had not been terminated, and (y) thereafter on such terms and at
such rates as may be approved by the New York State Public Service Commission or
such other regulatory body as may then have jurisdiction, or if rates for such
transportation are not then subject to regulatory approval, at rates determined
in accordance with the methodology then most recently utilized by a regulatory
body having jurisdiction over the local transportation of natural gas in New
York State. Tenant shall not dispose of the rights to any Project Pipeline
except upon the conditions that (A) the acquiror of such rights shall be bound
to afford transportation of natural gas to the Facility to the extent described
in the preceding sentence, (1) for the remainder of the Term, on the terms and
at the rates described in clause (x) of such sentence, and (2) for five years
after the expiration of the Term, on the terms and at the rates described in
clause (y) of such sentence, and (B) if the acquiror elects to abandon or
decommission the Project Pipeline at any time within five years after the
expiration of the Term, it shall make such pipeline available for purchase by
Landlord at the then depreciated book value of such pipeline.

     -------------
or the Facility more than 60 days after the expiration or earlier termination of
this Lease, may, at the

                                      -22-
<PAGE>

option of Landlord, be deemed to have been abandoned by Tenant and may be
retained by Landlord as its property, or disposed of, without accountability, by

terminate on the date title passes or possession is taken, whichever occurs
first. If less than all or substantially all of the Premises and the Facility is
taken, this Lease shall continue in full force and effect as to the portions not
taken. For purposes of this Article substantially all of the Premises and the

and distributed as follows:

          (a) First, the amount determined in the Condemnation Proceedings to be
the value of the Premises taken, exclusive of all improvements, shall be paid to
Landlord. If this amount is not separately determined in the Condemnation
Proceedings, it shall be determined by agreement between Landlord and Tenant or,
if they do not agree, by a court having jurisdiction in the matter.

          (b) Second, the balance of the net award shall be paid to the holder
of any Permitted Mortgage to the extent of the then unpaid amounts secured by
such mortgage.

          (c) Third, from the remaining balance of the net award, the amount of
the accrued Subordinated User Charges and Deferred User Charges, with accrued
interest, under the Operating Agreement shall be paid to Landlord.

divided between Landlord and Tenant, in proportion to the relative present
values, at the time of the taking, of the Landlord's and the Tenant's interest
in the Facility, as determined by agreement between them or, if they do not
agree, by a court having jurisdiction in the matter.

     Section 21.03.  Partial Taking. If less than substantially all of the

option, after ten (10) days' notice to the defaulting party, or without notice
in case of an emergency, perform any of such obligations.

lending institution, provided at least 95% of the proceeds of any such
refinancing shall be applied for the foregoing purposes. The terms of any such

authorize Tenant, or imply any consent or agreement on the part of Landlord, to
subject Landlord's estate and interest in the Premises to any Permitted
Mortgage, encumbrance or charge.

"restore" or "the restoration"). The restoration shall be at least equal in

of the Facility ("the insurance proceeds") shall be paid to the holder of any
Permitted mortgage to be applied as required by the Permitted Mortgage and the
Consent and Agreement. If there is no Permitted Mortgage, the insurance proceeds

("the net insurance proceeds"), shall be disbursed in accordance with the
following subparagraphs (c), (d) and (e).

     subcontractors, materialmen, engineers, architects or other persons who
     have rendered services or furnished materials for the restoration, a
     description of the services and materials and the amounts due each person,
     and that no part of the amount requested has been included in any other
     request by Tenant;

               B.  except for the amount requested, after due inquiry, no other
     amounts are due on the date of the certificate for labor, wages, materials,
     supplies or services in connection with the restoration;

               C.  the cost of labor and materials required to complete the

     payment of the amount requested; and

               D.  the restoration is in compliance with the plans and
     specifications approved by Landlord and has been performed in accordance
     with the provisions applicable to the original Work.

          (d) Upon completion of the restoration, there shall be paid to Tenant,
from, and only to the extent of, the net insurance proceeds, an amount equal to
100% of the costs of work completed and materials furnished in the restoration

          (e) Upon receipt of evidence satisfactory to Landlord that the
restoration has been completed in accordance with the provisions of this Lease
and its cost paid in full and that there are no liens upon the Premises or the
Facility, the net insurance proceeds remaining, if any, shall be paid to Tenant,
provided Tenant is not in default under this Lease.

          (f) Subject to the rights of the holders of any Permitted Mortgage, if
this Lease shall be terminated for any reason other than in accordance with this
Article or Article 21, Landlord shall be entitled to all insurance proceeds, and
Tenant shall have no interest in, nor any right, title, or claim to them.

          (g) No destruction or damage to the Facility or any part of it shall
permit Tenant to surrender this Lease or shall relieve Tenant from its
obligation to pay rent or from any of its other obligations under this Lease.
Tenant waives any rights now or in the future conferred upon it by statute or
otherwise to quit or surrender this Lease or to any suspension, diminution,
abatement or reduction of rent on account of any destruction or damage to the
Facility or the Premises.

          (h) If the Facility is damaged by fire or otherwise during the last
three (3) years of the term of this Lease and the cost of restoration will
exceed 50% of the then replacement value of the Facility, Tenant may elect to
terminate this Lease on at least thirty (30) days' notice to Landlord, given
within ninety (90) days after the damage. If Tenant elects to terminate, this
Lease shall end on the date specified in the notice, provided Tenant shall
restore the Premises to its condition prior to the commencement of the
construction of the Cogeneration Facility ("the restoration"), which restoration
shall be performed in accordance with all of the requirements of this Agreement
applicable to the original Work. Subject to the rights of the holder of any
Permitted Mortgage, all insurance proceeds shall first be made available for the
costs of

                                      -38-
<PAGE>

restoration by Tenant and the balance shall be the sole property of Landlord,
and Tenant shall not have any right or claim to the insurance proceeds. The
termination of the Lease under this Section shall not release Tenant from its
obligation to pay rent or from any of its other obligations under this Lease
accrued or payable for the period prior to the effective date of termination.

     The Issuer hereby represents and warrants to the Guarantor as follows:

     (a) The Issuer is a corporate governmental agency constituting a body
corporate and politic and a public benefit corporation duly organized, existing,
and established under the laws of the State of New York (including the Act), and
is authorized and empowered to enter into this Lease and the transactions
contemplated herein and to carry out its obligations hereunder. Based upon the

By proper official action of its members, the Issuer has duly authorized the
execution and delivery of this Lease and the Issuer's participation in the
transactions contemplated hereby.

                                       6
<PAGE>

     (b) Neither the execution and delivery of this Lease, the consummation of
the transactions contemplated hereby, nor the fulfillment of or compliance with
the provisions of the other Financing Documents to which the Issuer is a party
will conflict with or result in a breach by the Issuer of any of the terms,
conditions, or provisions of the Act, the By-Laws of the Issuer, or any order,
judgment, restriction, agreement, or instrument to which the Issuer is a party
or by which it is bound or will constitute a default by the Issuer under any of
the foregoing.

     (c) The Issuer will cause the Project to be constructed and installed and
the Easements acquired and will sublease the Leased Premises and the Outside
Easements (including the Pipeline located on such Easements) to the Guarantor

such Easements) to the Guarantor pursuant to this Lease, all for the purpose of
advancing the job opportunities, health, general prosperity, and economic
welfare of the people of the State of New York and improving their standard of
living.

     (d) By Resolution adopted on November 15, 1990, the Issuer determined that
based upon the review of the materials submitted, representations made by the
Guarantor relating to the Project and the findings statement (the "Findings
Statement") of the City of Syracuse, acting as lead agency pursuant to the New
York State Environmental Conservation Law (the "Lead Agency"), construction of
the Project would not have a "significant impact" on the environment within the
meaning of such quoted term under the New York State Environmental Quality
Review Act.

                                       7

     (e) The Issuer is issuing the Bonds in order to finance the development,
acquisition and construction of the Project. The Bonds mature, bear interest,
are redeemable and have the other terms and provisions set forth in the
Financing Agreement.

     (f) The Financing Documents constitute, or upon their execution and
delivery in accordance with the terms thereof will constitute, valid and legally
binding obligations of the Issuer, enforceable in accordance with their
respective terms.

     (g) No suit, action or arbitration, or legal, administrative or other
proceeding is pending or has been threatened against the Issuer that would
materially and adversely affect the validity or enforceability of this Lease or
the ability of the Issuer to fulfill its commitments hereunder, or that could
result in any material adverse change in the business or financial condition of
the Issuer.

     The Guarantor hereby represents and warrants to the Issuer as follows:

     (a) The Guarantor is a limited partnership organized and existing under the
laws of the State of Delaware, is duly authorized to do business in the State of
New York, has the power and authority to enter into this Lease and the other
Financing Documents to which it is a party and to carry out its obligations
hereunder and thereunder, and has duly authorized the execution, delivery, and
performance of this Lease and the other Financing Documents.

                                       8
<PAGE>

     (b) The Financing Documents constitute, or upon their execution and
delivery in accordance with the terms thereof will constitute, valid and legally
binding obligations of the Guarantor, enforceable in accordance with their
respective terms.

     (c) The Guarantor has caused the Ground Lease and the City Easements to be
assigned to the Issuer and has caused the Outside Easements to be leased to the
Issuer and will cause the Project to be constructed and improved all for the
purposes of promoting the prosperity and general welfare of all citizens of the
State of New York.

     (d) Neither the execution and delivery of the Financing Documents to which
the Guarantor is a party, the consummation of the transactions contemplated
thereby, nor the fulfillment of or compliance with the provisions thereof will:

          (1) Result in a breach of, or conflict with any term or provision in,
     the Partnership Agreement or this Lease;

          (2) Require any consent under (except for consents which have been
     received) or result in a breach of or default under any credit agreement,
     indenture, purchase agreement, mortgage, deed of trust, commitment,
     guaranty, or other agreement or instrument to which the Guarantor is a
     party or by which it or any interest of the Guarantor in any kind of
     property or asset, whether real, personal or mixed, or tangible or
     intangible (the "Property") may be bound or affected; or

          (3) Conflict with or violate any existing law, rule, regulation,
     judgment, order, writ, injunction, or decree of any Governmental Authority
     having jurisdiction over the Guarantor or any of the Property of the
     Guarantor.

                                       9
<PAGE>

     (e) No suit, action or arbitration, or legal, administrative or other
proceeding is pending or has been threatened against the Guarantor that would
materially and adversely affect the validity or enforceability of this Lease or
the ability of the Guarantor to fulfill its commitments hereunder, or that could
result in any material adverse change in the business or financial condition of
the Guarantor.

     (f) The Issuer's execution and delivery of this Lease and its participation
in the transactions contemplated hereby, including its assistance in financing a
portion of the cost of the Project:

          (1) Has been an important consideration in the Guarantor's decision to
     construct and equip the Project in the City of Syracuse; and

          (2) Will not result in the removal of an industrial or manufacturing
     plant or commercial activity of any Project occupant, other than the
     Guarantor, from one area of the State of New York to another area of the
     State of New York or in the abandonment of one or more plants or facilities
     of any user, occupant, or proposed user or occupant of the Project, other
     than the Guarantor, located within the State of New York.

     (g) So long as the Issuer owns the Facility and is the lessee under the
Ground Lease and has an interest in the Project, the Project is and will
continue to be a "project" (as such quoted term is defined in the Act), and the
Guarantor will not take any action (or omit to take any action required by the
Financing Documents or which the Issuer or the Agent, together with Issuer's
counsel, advise the Guarantor in writing should be taken), or allow any action
to be

                                       10
<PAGE>

taken, which action (or omission) would in any way cause the Project not to
constitute a "project" (as such quoted term is defined in the Act).

     (h) The City of Syracuse, acting as lead agency pursuant to the State of
New York's Environmental Conservation Law has issued a findings statement as
required by 6 NYCRR Part 617.9(c) stating that it has considered the draft
environmental impact statement, the supplemental environmental impact statement
and the final environmental impact statement prepared in connection with the
acquisition, construction and installation of the Project and has certified that
(i) the requirements of Article 8, New York State Environmental Conservation Law
and 6 NYCRR Part 617 have been met, (ii) consistent with social, economic and
other essential considerations from among the reasonable alternatives thereto,
the action approved is one which minimizes or avoids adverse environmental
effects to the maximum extent practicable, including the effects disclosed in
the environmental impact statement, and (iii) consistent with social, economic
and other essential considerations, to the maximum extent practicable, adverse
environmental effects revealed in the environmental impact statement process
will be minimized or avoided by incorporating as conditions to the Lead Agency's
decision forming the basis for the Findings Statement the mitigative measures
which were identified as practicable.

     (i) The Project and the operation thereof will comply in all material
respects with all applicable building, zoning, environmental, planning, and
subdivision laws, ordinances, rules, and regulations of Governmental Authorities
having jurisdiction over the Project (the applicability of such being determined
both as if the Issuer were the owner of the Project and as if the Guarantor, and
not the Issuer, were the owner of the Project).

                                       11
<PAGE>

     (j) Except for the Outside Easements and that part of the Pipeline
constructed on the Outside Easements, after completion of the Project no part of
the Project will be located outside of the City of Syracuse, New York.

     (k) Except as disclosed in Exhibit W to the Financing Agreement or in the
Hazardous Substance Reports, as of the date hereof the Guarantor has no
knowledge of hazardous, nuclear or toxic waste or substance contamination
affecting the Leased Premises which would require remedial action under any
Clean-Up Laws (as defined in Section l0.3(a)(7)). The Guarantor has exercised
due diligence to review the report dated December 1989 entitled "Environmental
Liability Assessment, Syracuse University Steam Station" prepared by O'Brien &
Gere Engineers, Inc. to ascertain whether the Leased Premises are or have been
affected by the presence of any Hazardous Substances that could necessitate
taking remedial or protective action or that could cause harm to persons,
property, the environment, or the Leased Premises.

     (l) The Construction Contract obligates the Contractor to: (i) hire and
employ at the Leased Premises skilled workers from the local labor force, that
being residents of the City of Syracuse and Central New York, and to exhaust
that resource of workers before those from another geographic residence are
hired to perform work at the Leased Premises; (ii) report quarterly to the
Issuer until substantial completion of the Facility, the residence of workers
employed by the Contractor at the Leased Premises, such report to identify
workers only by the zip code of their residence; (iii) cause the local labor
force hired by the Contractor who work at the Leased Premises to comprise women
and minorities whenever and wherever it is deemed practicable; (iv) pay wages to
the local labor force hired by the Contractor for work at the Leased Premises at
the hourly rate established as "prevailing wages" for their work in the Syracuse
area;

                                       12
<PAGE>

and (v) provide the local labor force hired by the Contractor for work at the
Leased Premises with health and welfare and pension benefits equivalent to those
established by the prevailing wage standard for their work in the Syracuse area.
The Guarantor shall use its best efforts to cause Mr. Adam Victor, or his
designee, to remain available as a liaison between the Issuer and the Contractor
to promote and create an amicable and harmonious relationship between the two to
insure that the Facility will be built within the prescribed time frame and
without disruption.

     The Issuer, to the extent of its interest therein, shall not sell, assign,
transfer, encumber, or pledge as security the Project or any part thereof except
as contemplated or allowed by the terms of the Financing Documents.

     (a) The Guarantor shall perform, or cause to be performed, for and on
behalf of the Issuer, each and every obligation of the Issuer, which is within
the control of the Guarantor, under and pursuant to the Operative Documents, and
shall defend, indemnify, and hold harmless the Issuer and its members, officers,
agents (other than the Guarantor) and employees from and against every expense,
liability, or claim arising out of the failure of the Guarantor to fulfill its
obligations under the provisions of this subsection 2.4(a).

     (b) The Guarantor shall cause all notices as required by law to be given
and shall comply or cause compliance with all laws, ordinances, municipal rules,
and regulations and requirements of all Governmental Authorities applying to or
affecting the conduct of work on or the operation of the Project (the
applicability of such laws, ordinances, rules, and regulations to

                                       13
<PAGE>

be determined both as if the Issuer were the owner of the Project and as if the
Guarantor, and not the Issuer, were the owner of the Project) and the Guarantor
will defend and save the Issuer and its officers, members, agents (other than
the Guarantor), and employees harmless from all fines and penalties due to
failure to comply therewith.

     (c) In the event of the termination of this Lease pursuant to Section 6.2,
10.10 or 12.2 hereof, the Guarantor agrees to purchase the Project in accordance
with the provisions of Section 6.3 hereof.

     (d) The Guarantor shall not allow the manufacture (except to the extent, if
any, that such substances are a byproduct of the operation of the Project and
then only to the extent such manufacture is in compliance in all material
respects with applicable laws) or disposal of any Hazardous Substances on the
Leased Premises or otherwise at the Facility, and shall only allow the storage
or presence of Hazardous Substances on the Leased Premises or otherwise at the
Facility to the extent necessary in connection with the operation of the Project
and if such storage or presence is in compliance with applicable laws.

     (e) The Issuer shall have the right at any time after the occurrence and
during the continuance of an Event of Default which results from a breach of
Section 2.4(d), but in no event more than once in any year, to conduct an
environmental audit of the Facility by an environmental consultant reasonably
acceptable to both the Issuer and the Guarantor (the "Environmental Consultant")
and the Guarantor shall cooperate in the conduct of the same. The cost of such
audits shall be borne by the Guarantor.

                                       14
<PAGE>

     (f) The Guarantor will not lease or sublease the whole or any portion of
the Project for an unlawful purpose.

     (g) The Guarantor shall take all actions necessary to cause the Tenneco
Letter of Credit and any replacements thereof to be issued as required in the
Financing Agreement.

                                  ARTICLE III

                                 USE OF PROJECT

     During the term of this Lease, the Guarantor shall be entitled to all of
the benefits from the use of the Project (including, but not limited to, the
Leased Premises, the Easements, the Facility and the Pipeline) in any manner not
otherwise prohibited by the Financing Documents, so long as such use does not
cause the Project to fail to qualify as a "project" under the Act.

acquired by the Guarantor and intended to be incorporated or installed in and to
become part of the Project shall vest in the Issuer immediately upon payment
thereof or incorporation or installation in the Project, whichever shall first
occur; provided, however, that all alterations, improvements and additions made
to the Existing Plant, other than the Auxiliary System, and whether or not
affixed or moveable, shall upon installation become the property of the
University to the extent required under the Operating Agreement. The Guarantor
shall execute, deliver, and record or file all instruments necessary or
appropriate to vest title to any such property (other than the property
described in the proviso to the preceding sentence) in the Issuer and shall take
all action necessary or appropriate to protect such title against claims of any
third Persons. The Issuer agrees that the Auxiliary System shall become the
property of the University upon the expiration or earlier termination of the
Operating Agreement in accordance with its terms.

     (b) The Guarantor has given, or will give or cause to be given, all notices
and has complied, or will comply or cause compliance with, all existing laws,
ordinances, rules, regulations, and requirements of all Governmental Authorities
applying to or affecting the conduct of work on, or the operation of, the
Project (the applicability of such laws, ordinances, rules, and regulations to
be determined both as if the Issuer were the owner of the Project and as

                                       16
<PAGE>

if the Guarantor, and not the Issuer, were the owner of the Project) and the
Guarantor will defend, indemnify, and save the Issuer and its officers, members,
agents (other than the Guarantor), servants, and employees harmless from all
fines and penalties due to failure to comply therewith.

     Simultaneously with the delivery of this Lease, the Issuer will deliver the
Bonds in the aggregate principal amount of $204,300,000 under and pursuant to a
resolution adopted by the Issuer authorizing the issuance of the Bonds. The
proceeds of sale of the Bonds received by the Issuer shall be deposited in the
Construction Account and made available to the Guarantor in accordance with the
provisions of this Lease and the Financing Agreement. Pending application,
amounts so deposited may be invested as provided in the Financing Agreement.

     In the event that the proceeds of the Bonds are not sufficient to pay in
full all costs of the development, acquisition, construction and equipping of
the Project, the Guarantor shall, to the extent required by the Financing
Agreement, complete such development, acquisition, construction and equipping
and pay all such sums as may be in excess of the proceeds of the Bonds. All
portions of the Project developed, acquired, constructed or equipped at the
Guarantor's cost shall immediately, upon such development, acquisition,
construction or equipping, be subject to the Liens of the Mortgages.

                                       17

     In the event of a default by any contractor, subcontractor, or materialman
under any contract made by them in connection with construction, equipping,
operation or maintenance of the Project or in the event of a breach of warranty
or other liability with respect to any materials, workmanship, or performance
guaranty, the Guarantor may, in its discretion, proceed, either separately or in
conjunction with others, to enforce the remedies of the Guarantor and/or the
Issuer against the contractor, subcontractor, or materialman so in default and
against each surety for the performance of such contract. The Guarantor may
prosecute or defend any action or proceeding or take any other action involving
any such contractor, subcontractor, materialman, or surety which the Guarantor
deems reasonably necessary. The Guarantor shall advise the Issuer of any actions
or proceedings taken hereunder. No such suit shall relieve the Guarantor of any
of its obligations under this Lease.

<PAGE>

Leased Premises, the Facility, the Pipeline, the Outside Easements, the City

certain Consent and Agreement dated as of April 5, 1991 among the University,

pursuant to this Section 6.2(b) and upon compliance with the requirements set
forth in Section 6.2(c) hereof.

     (c) In the event the Guarantor exercises its option to terminate this Lease
in accordance with Section 6.2(b) hereof or the Issuer exercises its right to
terminate this Lease in accordance with Section 6.2(a), 10.10, or 12.2 hereof,
the following payments shall be made by the Guarantor:

               (i) to the Agent, all amounts payable by the Issuer and/or the
          Guarantor, if any, under the Financing Documents; provided, however,
          that in lieu of making such payments the Guarantor may deliver to the
          Issuer a release, in form reasonably satisfactory to the Issuer,
          pursuant to which the Issuer is released by the Agent and the Banks
          from its obligations under the Financing Documents;

               (ii) to the Issuer, an amount certified by the Issuer sufficient
          to pay all unpaid fees and expenses of the Issuer and of its members,
          officers, employees and agents (other than the Guarantor) incurred
          under this Lease and the Mortgages; and

               (iii)  to the Issuer or the City of Syracuse, as appropriate, all
          amounts which are then due and unpaid under the PILOT Agreement.

                                       21

     Upon the termination of this Lease pursuant to Section 6.2(a), 6.2(b),
10.10 or 12.2 or otherwise, or upon the expiration of the term of this Lease,
the Guarantor shall purchase from the Issuer and the Issuer shall convey to the
Guarantor, in consideration of one dollar ($1.00), the Issuer's entire right,
title and interest in the Project, including, without limitation, the Issuer's
rights and interest in, to and under the Ground Lease, the Facility, the
Pipeline, the Easements, the Personalty and the Operative Documents (other than
the Unassigned Rights). If the Guarantor is required to purchase the Project
pursuant to the preceding sentence, the Guarantor shall give written notice to
the Issuer and the Agent (i) declaring the Guarantor's election to purchase, and
(ii) fixing the date of the closing of such purchase, which shall not be later
than 30 days after any notice sent to the Guarantor pursuant to Section 6.2(a)
of the date on which this Lease is to be terminated (subject to any other
provision of this Lease or the PILOT Agreement which may require an earlier
closing). At the closing of the purchase of the Project pursuant to this Section
6.3, the Issuer shall deliver and request the Agent to deliver to the Guarantor
all necessary documents (a) to convey to the Guarantor all of the Issuer's
right, title and interest in and to the Project, as it exists, subject only to
(i) any Liens to which title to such Project was subject when conveyed to the
Issuer, (ii) any Liens created at the request of the Guarantor or to which the
Guarantor consented or in the creation of which the Guarantor acquiesced, (iii)
Permitted Liens, and (iv) any Liens resulting from the failure of the Guarantor
to perform or observe any of the agreements on its part contained in this Lease
or arising out of an Event of Default, (b) to release and convey to the
Guarantor all of the Issuer's right, title and interest in and to any rights of
action or any net proceeds of insurance or condemnation awards with respect to
the Project, and (c) to discharge and release any other Liens or encumbrances
held by the Issuer and not set forth

                                       22

above. Upon the due conveyance and assignment of all of the Issuer's right,
title and interest in the Project to the Guarantor, the Guarantor shall deliver
a release and agreement that the exculpation provisions and the obligations of
the Guarantor in Sections 2.4(a) and 10.3 hereof shall survive such conveyance
or purchase of the Project. Unless all amounts due to the Banks under the
Financing Documents shall have been paid in full, any conveyance of the Issuer's
interest in the Project to the Guarantor pursuant to this Section 6.3 shall be
subject to the Bank's security interests in and mortgages on the Project and the
various rights and interests comprising the Project.

                                  ARTICLE VII

                      RENTAL OBLIGATIONS AND ISSUER'S FEE

     (a) Until the obligations of the Issuer under the Bonds and the Financing
Agreement have been paid in full, the Guarantor shall pay rent under this Lease
in an amount which equals the principal of, interest on, any premium on, and all
other sums due on the Bonds, and all other sums the Issuer is required to pay
under the Financing Agreement, such rent hereunder to be due when the
corresponding amounts are due from the Issuer under the Bonds and the Financing
Documents and subject to the same grace periods, if any. Thereafter, the rent
under this Lease shall equal one dollar per annum and shall be due in arrears on
each December 31. Until the Issuer's obligations under the Bonds and the
Financing Agreement have been paid in full, all rental payments required under
this Section 7.1 shall be paid by the Guarantor directly to the

                                       23
<PAGE>

Agent, and all such payments by the Guarantor to the Agent or made to the Agent
from any of the Accounts shall be credited against the Guarantor's obligations
to the Issuer hereunder.

     (b) The Guarantor agrees to make the above-mentioned rental payments,
without any further notice, in lawful money of the United States of America as,
at the time of payment, shall be legal tender for the payment of public and
private debts.

     In consideration of the Issuer entering into this Lease, the Financing
Agreement and certain Financing Documents, in addition to any other amounts
payable under this Lease the Guarantor shall pay to the Issuer a fee of
$500,000, which shall be paid on the Initial Funding Date under the Financing
Agreement.

     (a) The obligations of the Guarantor to make the rental payments due under
this Lease and to perform and observe any and all of the other covenants and
agreements on its part contained herein are general obligations of the Guarantor
and are absolute and unconditional irrespective of any defense or any rights of
set-off, recoupment, or counterclaim it may otherwise have against the Issuer.
The Guarantor agrees that it will not suspend, discontinue, abate or be entitled
to any diminution of any rental required by, or fail to observe any of its other
covenants or agreements contained in this Lease, or terminate this Lease for any
cause whatsoever, including, without limiting the generality of the foregoing,
failure to complete the construction and equipping of the Project, any defect in
the title, design, operation, merchantability, fitness, or condition of the
Project, or any part thereof, or in the suitability of the Project, or any part

                                       24
<PAGE>

thereof, for the Guarantor's purposes or needs, or failure of consideration for,
destruction of or damage to, or condemnation of title to, or the use of all or
any part of the Project, any change in the tax or other laws of the United
States of America or of the State of New York, or any political subdivision
thereof, or any failure of the Issuer to perform and observe any agreement,
whether express or implied, or any duty, liability or obligation arising out of
or in connection with this Lease.

     (b) Nothing contained in this Section shall be construed to release the
Issuer from the performance of any of the agreements on its part contained in
this Lease, and in the event the Issuer should fail to perform any such
agreement, the Guarantor may institute such action against the Issuer as the
Guarantor may deem necessary to compel performance (subject to the provisions of
Section 13.10).

                                  ARTICLE VIII

                MAINTENANCE, MODIFICATIONS, TAXES, AND INSURANCE

     During the term of this Lease, the Guarantor shall operate, maintain,
repair and restore the Project in the manner and to the extent required under
the Financing Agreement and the Operative Documents.

                                       25
<PAGE>

     (a) The Guarantor shall pay, or cause to be paid, the following, as the
same respectively become due unless the Guarantor is actively and in good faith
contesting any such taxes, assessments or other changes as permitted by Section
8.2(b):

          (1) All taxes and governmental charges of any kind whatsoever which
     may at any time be lawfully assessed or levied against or with respect to
     the Project or any part thereof;

          (2) All utility and other charges, including "service charges,"
     incurred or imposed for the operation, maintenance, use, occupancy, upkeep,
     and improvement of the Project, the non-payment of which would create, or
     entitle the obligee to impose, a Lien on the Project;

          (3) All assessments and charges of any kind whatsoever lawfully made
     by any Governmental Authority against the Project for public improvements;
     and

          (4) All payments in lieu of taxes, required to be made to the Issuer
     or the City of Syracuse under the terms of the PILOT Agreement.

     (b) Notwithstanding anything in Section 8.2(a) to the contrary, the
Guarantor may in good faith actively contest any taxes, assessments and other
charges described in Section 8.2(a) (except that with respect to the PILOT
Agreement, the Guarantor shall not contest the validity of such agreement but
may only dispute, in good faith, the calculation of the amounts due thereunder),
provided that such action does not constitute an Event of Default under the
Financing Agreement.

                                       26
<PAGE>

     The Guarantor shall at all times maintain insurance with respect to the
Project against such risks and for such amounts as are customarily insured
against by businesses of like size and type, paying (as the same become due and
payable) all premiums with respect thereto; provided, however, that, if the
premiums are not timely paid, the Issuer may pay such premiums and the Guarantor
shall pay immediately upon demand all sums so expended by the Issuer. The
maintenance of such insurance as is required under Section 5.20 of the Financing
Agreement or as is otherwise acceptable to the Agent shall satisfy the
Guarantor's obligations under this Section 8.3.

     All proceeds of insurance maintained pursuant to the Financing Agreement or
Section 8.3 of this Lease shall be applied in accordance with the terms of the
Financing Agreement until the obligations of the Issuer under the Bonds and the
Financing Agreement have been satisfied in full. Thereafter, all such proceeds
shall be payable to the Guarantor. Notwithstanding the foregoing, the proceeds
of any insurance required to be maintained by the Guarantor pursuant to the
Operating Agreement shall be applied as required under the terms of the
Operating Agreement.

                                   ARTICLE IX

                     DAMAGE, DESTRUCTION, AND CONDEMNATION

     (a) If the Project shall be damaged or destroyed, in whole or in part:

                                       27
<PAGE>

          (1) The Issuer shall have no obligation to replace, repair, rebuild,
     or restore the Project, but the Issuer shall make all insurance proceeds
     payable to it in connection with any such damage or destruction available
     to the Guarantor to be applied in accordance with the terms of the
     Financing Agreement;

          (2) There shall be no abatement or reduction in the rent payable by
     the Guarantor under this Lease (whether or not the Project is replaced,
     repaired, rebuilt, or restored); and

          (3) The Guarantor shall promptly give notice thereof to the Issuer.

     (b) Subject to the provisions of the Financing Agreement, the Guarantor may
adjust all claims under any policies of insurance required by Section 5.20 of
the Financing Agreement.

     (a) If title to, or the use of, less than substantially all of the Project
shall be taken by condemnation:

          (1) The Issuer shall have no obligation to restore the Project, but
     the Issuer shall make all proceeds of such condemnation payable to it
     available to the Guarantor to be applied in accordance with the terms of
     the Financing Agreement;

          (2) There shall be no abatement or reduction in the rent payable by
     the Guarantor under this Lease (whether or not the Project is restored);
     and

          (3) The Guarantor shall promptly give notice thereof to the Issuer and
     the Agent.

                                       28
<PAGE>

     (b) Subject to the provisions of the Financing Agreement, the Guarantor
shall have sole control of any condemnation proceeding with respect to the
Project, or any part thereof, and may negotiate the settlement of any such
proceeding.

     All replacements, repairs, rebuilding or restorations made to the Project,
whether or not requiring the expenditure of the Guarantor's own moneys, shall
automatically become part of the Project as if the same were specifically
described herein and title to such replacements, repairs, rebuilding or
restoration shall immediately vest in the Issuer; provided, however, that title
to any replacements, repairs, rebuilding or restoration of the Existing Plant
shall, to the extent required under the Operating Agreement, become vested in
the University.

     Subject to the requirements of the Financing Agreement, the Guarantor shall
not have any obligation hereunder to repair, replace, restore or reconstruct the
Project in the event of any damage, destruction or condemnation of all or any
portion of the Project.

                                   ARTICLE X

                               SPECIAL COVENANTS

     The Issuer covenants and agrees that it has full right and lawful authority
to enter into this Lease for the full term hereof, and that, subject to the
terms and provisions of the Financing Documents, unless and until this Lease is
terminated by the Issuer or the Guarantor, the

                                       29
<PAGE>

Guarantor shall have, hold and enjoy, during the term hereof, peaceful, quiet
and undisputed possession of the Project.

     THE ISSUER IS NOT MAKING ANY WARRANTY, EITHER EXPRESS OR IMPLIED, AS TO THE
CONDITION, TITLE, DESIGN, OPERATION, MERCHANTABILITY, OR FITNESS OF THE PROJECT,
OR ANY PART THEREOF, OR AS TO THE SUITABILITY OF THE PROJECT OR ANY PART THEREOF
FOR THE GUARANTOR'S PURPOSES OR NEEDS. NO WARRANTY OF FITNESS FOR A PARTICULAR
PURPOSE OR MERCHANTABILITY IS MADE. IN THE EVENT OF ANY DEFECT OR DEFICIENCY OF
ANY NATURE, EITHER PATENT OR LATENT, THE ISSUER SHALL NOT HAVE ANY
RESPONSIBILITY OR LIABILITY WITH RESPECT THERETO.

     (a) The Guarantor hereby releases the Issuer and its members, officers,
agents (other than the Guarantor) and employees from, agrees that the Issuer and
its members, officers, agents (other than the Guarantor) and employees shall not
be liable for, and agrees to indemnify, defend, and hold the Issuer and its
members, officers, agents (other than the Guarantor) and employees harmless from
and against, any and all claims arising as a result of the Issuer's undertaking
the Project, including, but not limited to:

          (1) Liability for loss or damage to property or bodily injury to or
     death of any and all Persons that may be occasioned by any cause whatsoever
     (including latent and

                                       30
<PAGE>

     patent defects) pertaining to the Project, or arising by reason of or in
     connection with the occupation or the use thereof, or the presence on, in,
     or about the Project;

          (2) Liability arising from or expense incurred by the Issuer's owning,
     selling, constructing or equipping of the Project, including, without
     limiting the generality of the foregoing, all liabilities or claims arising
     as a result of or in connection with the Issuer's obligations under the
     Operative Documents;

          (3) All claims arising from the exercise by the Guarantor of the
     authority conferred upon it by the Agency Agreement of even date herewith
     between the Issuer and the Guarantor;

          (4) All costs incurred in connection with the maintenance, repair,
     restoration, rebuilding and operation of the Project, or any portion
     thereof, to the extent required under the Financing Agreement;

          (5) All taxes of any kind (and by whomsoever imposed) assessed against
     the Project or any portion thereof;

          (6) All causes of action and attorneys' fees and other expenses
     incurred in connection with any suits or actions which may arise as a
     result of any of the foregoing or as a result of establishing a breach by
     the Guarantor of the terms of any of the Operative Documents; and

          (7) Any liability, loss, cost, damage or expense (including, without
     limitation, reasonable attorneys' fees) arising from (i) the imposition or
     recording of a lien by any

                                       31
<PAGE>

     Federal, state or local government or governmental agency or authority
     pursuant to any Federal, state or local statute or regulation relating to
     Hazardous Substances or the removal thereof ("Clean-Up Laws"); (ii) claims
     of any private parties regarding violations of Clean-Up Laws; and (iii)
     costs and expenses (including, without limitation, reasonable attorneys'
     fees and fees incidental to the securing of repayment of such costs and
     expenses) incurred by the Issuer in connection with its compliance with any
     order issued pursuant to any Clean- Up Laws by any Federal, state or local
     governmental agency or authority. The obligations of the Guarantor under
     this paragraph (7) of this Section 10.3(a) shall not be limited by Section
     13.10(c).

Subject to paragraph (c) of this Section 10.3, all of the foregoing indemnities
shall apply notwithstanding the fault or negligence (other than gross negligence
or willful misconduct) on the part of the Issuer or any of its officers,
members, agents or employees and irrespective of any breach of statutory
obligation or any rule of comparative or apportional liability.

     (b) In the event of any claim against the Issuer or its members, officers,
agents (other than the Guarantor) or employees by any employee of the Guarantor,
or any contractor of the Guarantor, or anyone directly or indirectly employed by
any of them, or any one for whose acts any of them may be liable, the
obligations of the Guarantor hereunder shall not be limited in any way by any
limitation on the amount or type of damages, compensation, or benefits payable
by or for the Guarantor or such contractor under workers' compensation laws,
disability benefit laws, or other employee benefit laws.

     (c) Notwithstanding any other provisions of this Lease, (i) the obligations
of the Guarantor pursuant to this Section 10.3 shall remain in full force and
effect after the termination

                                       32
<PAGE>

of this Lease until the expiration of the period stated in the applicable
statute of limitations during which a claim, cause of action, or prosecution
relating to the matters herein described may be brought, and the payment in full
or the satisfaction of such claim, cause of action or prosecution, and the
payment of all expenses and charges incurred by the Issuer or its officers,
members, agents (other than the Guarantor) or employees, relating thereto, and
(ii) the Guarantor shall not have any obligation to indemnify the Issuer or its
members, officers, agents (other than the Guarantor) or employees for any loss,
liability, damage, expense or claims whatsoever arising from the gross
negligence or willful misconduct of any of such Persons (other than the
Guarantor).

     (d) In order for the Issuer or any other Person who may be entitled to
indemnification from the Guarantor under this Section 10.3 or any other
provision of this Lease (each of the foregoing, an "Indemnitee") to be entitled
to indemnification with respect to any liability or claims against such
Indemnitee, such Indemnitee must notify the Guarantor in writing of any claim or
demand made against such Indemnitee within 10 business days after receipt by
such Indemnitee of written notice of such claim; provided, however, that the
failure of an Indemnitee to provide notice to the Guarantor of a claim or demand
within such 10 business day period shall not affect its right to indemnification
hereunder if such delay does not in any material way prejudice or impair the
Guarantor's ability to contest or defend against such claim or demand or to
assert an offset or counter-claim.  Each Indemnitee shall also deliver to the
Guarantor copies of all notices and documents received by such Indemnitee
relating to any such claim or demand for which such Indemnitee is seeking
indemnification from the Guarantor. The Guarantor shall be entitled to
participate, at its expense, in the defense of any claim made against any
Indemnitee

                                       33
<PAGE>

and, if it so chooses, to assume the defense thereof at its cost with counsel
selected by it who shall be reasonably acceptable to such Indemnitee. An
Indemnitee may, in any such case, retain its own counsel at its own expense to
participate in the defense of such claims. Each Indemnitee shall cooperate fully
in the defense and prosecution of any such claim. The Guarantor shall not be
obligated to indemnify any Indemnitee for the amount of any settlement paid by
such Indemnitee in connection with any claim unless the Guarantor has approved
the settlement in writing, the Guarantor agreeing that it will not unreasonably
withhold its consent to a proposed settlement which is approved by the affected
Indemnitee. An Indemnitee shall, at the Guarantor's request, agree to the terms
of any settlement of any claim for which the Indemnitee is entitled to
indemnification hereunder which is negotiated by the Guarantor so long as such
settlement involves only the payment of money which shall be paid by the
Guarantor at the time of settlement; settlement on any other terms shall require
the Indemnitee's written consent (which consent shall be conclusively presumed
by its execution of a settlement agreement or stipulation of settlement).

     (e) Within 30 days after the Guarantor's receipt of demand therefor from
the Issuer, the Guarantor shall reimburse the Issuer for any expenses reasonably
incurred by the Issuer by reason of the Issuer's ownership, financing or leasing
of the Project or in connection with the performance of the Issuer's duties and
obligations under this Lease and the Operative Documents.

     The Guarantor agrees that during the term of this Lease the Issuer and its
duly authorized agents shall have the right to enter upon and to examine and
inspect the Project during normal

                                       34
<PAGE>

business hours and upon reasonable prior written notice to the Guarantor, and
provided that all such persons comply with applicable safety regulations and
insurance requirements.

     During the term of this Lease, the Guarantor will maintain its existence,
will not dissolve or otherwise dispose of all or substantially all of its
assets, and will not consolidate with or merge into another legal entity or
permit one or more other legal entities to consolidate with or merge into it.

     During the term of this Lease, the Guarantor shall, whenever requested by
the Issuer in writing, provide and certify, or cause to be certified, such
information concerning the Guarantor or its finances as the Issuer from time to
time reasonably considers necessary or appropriate, including, but not limited
to, such information as is necessary to enable the Issuer to make any reports
required by law or governmental regulation. The Issuer agrees that any
information provided to it by the Guarantor hereunder is confidential and
proprietary and the Issuer shall not permit the duplication, use or disclosure
of any such information to any Person (other than its attorneys, consultants,
employees or agents) unless authorized in writing by the Guarantor. Any
information provided by the Guarantor shall not be deemed confidential and
proprietary, and shall not be subject to the restrictions set forth in the
preceding sentence, if and to the extent that (i) at the time of disclosure,
such information is generally known by the public and any competitors of the
Guarantor, (ii) such information was in the Issuer's possession or available to
it on a non-confidential basis from a third party prior to its receipt of such
information from the Guarantor, (iii) such information is hereafter obtained by
the Issuer from a third party without

                                       35
<PAGE>

obligation of confidentiality, or (iv) such information is legally required to
be disclosed, in the opinion of the Issuer's counsel; provided, however, that
before any determination is made by the Issuer that any information is not
confidential and proprietary for any of the foregoing reasons and before any
such information is disclosed by the Issuer, the Issuer shall give the Guarantor
reasonable notice and a reasonable opportunity to prevent or contest such
disclosure.

     (a) The Guarantor agrees that it will, during any period in which the Bonds
remain unpaid, promptly comply in all material respects with all statutes,
codes, laws, acts, ordinances, orders, judgments, decrees, injunctions, rules,
regulations, permits, licenses, authorizations, directions, and requirements of
all Governmental Authorities, foreseen or unforeseen, ordinary or extraordinary,
which now or at any time hereafter affect the Guarantor's obligations hereunder
or are applicable to the Project, or any part thereof, or to any use, manner of
use, or condition of the Project, or any part thereof, the applicability of the
same to be determined both as if the Issuer were the owner of the Project, and
as if the Guarantor and not the Issuer were the owner of the Project.

     (b) Notwithstanding the provisions of subsection 10.7(a), the Guarantor
may, in good faith, actively contest the validity or the applicability of any
requirement of the nature referred to in said subsection 10.7(a), provided that
the Guarantor shall have first notified the Issuer of such contest. In such
event, the Guarantor may fail to comply with the requirement or requirements so
contested during the period of such contest and any appeal therefrom unless:

                                       36
<PAGE>

          (1) The Issuer shall notify the Guarantor that by failure to comply
     with such requirement or requirements the Liens of the Mortgages as to the
     Project may be endangered or the Project, or any part thereof, may be
     subject to loss or forfeiture, in which case the Guarantor shall promptly
     take such action with respect thereto as shall be reasonably satisfactory
     to the Issuer; or

          (2) The Issuer shall so notify the Guarantor that based on an opinion
     of counsel to the Issuer, a copy of which must accompany such notice, the
     Issuer or its members, officers, agents (other than the Guarantor), or
     employees may be liable for prosecution for failure to comply therewith, in
     which event the Guarantor shall promptly take such action with respect
     thereto as shall be satisfactory to the Issuer.

     (a) The Guarantor hereby represents and warrants that, except for Permitted
Liens, there are no Liens on the Project senior to the Mortgages.

     (b) The Guarantor hereby represents and agrees not to create, or suffer to
be created, any Lien, except for Permitted Liens, on the Project, or any part
thereof.

     (c) Notwithstanding the provisions of subsection 10.8(b), the Guarantor
may, in good faith, actively contest any such Lien, provided that the Guarantor
shall have first notified the Issuer of such contest. No action taken pursuant
to this Section 10.8 shall relieve the Guarantor from its obligation to make all
rental payments required by Section 7.1 hereof or any other payments required to
be made by the Guarantor, including, without limitation, payments due under the
PILOT Agreement.

                                       37
<PAGE>

     Should the Guarantor fail to make any payment or to do any act as herein
provided within 30 days after notice from the Issuer, then the Issuer may, but
need not, without releasing the Guarantor from any obligation herein, make or do
the same, including, without limitation, appearing in and defending any action
purporting to affect the rights or powers of the Guarantor or the Issuer and
paying all expenses, including, without limitation, reasonable attorneys' fees;
and the Guarantor shall pay immediately upon demand all sums so expended by the
Issuer under the authority hereof, together with the interest thereon at a rate
of ten (10%) percent per annum or the highest rate permitted by law, whichever
is lower.

     The Issuer makes no representation or warranty, either express or implied,
as to any prior or current use of, or contamination by, Hazardous Substances at
or affecting the Project. In the event that, within 30 days (or such longer
period as the Issuer and the Agent, after consultation with the Environmental
Consultant, deem reasonable) after its receipt from the Issuer or the
Environmental Consultant of an environmental audit prepared by the Environmental
Consultant which reports a violation of any Clean-Up Laws due to a condition
existing with respect to the Project, the Guarantor fails to commence and
continue with reasonable diligence at least one of the alternative remediation
actions recommended by the Environmental Consultant or an alternative
remediation action otherwise agreed to by the Issuer and the Guarantor to cure
such violation and the Issuer obtains an opinion of counsel that the Issuer may
be liable for any fees, penalties or assessments or may have civil or criminal
liability as a result of such violation, then the Issuer shall have the option
to terminate this Lease and convey the Project to the Guarantor

                                       38
<PAGE>

after the expiration of such 30-day period and after notice to the Guarantor and
the Agent, and the Guarantor shall have the obligation to accept such
conveyance, notwithstanding any other provision of this Lease. In the event of
such conveyance from the Issuer to the Guarantor, the Guarantor shall comply
with any other term or provision of this Lease, the Financing Agreement, the
Mortgages, or any of the Financing Documents which may become operative due to
such early conveyance of the Facility. Any such conveyance shall be subject to
the provisions of Section 6.3 and shall not terminate or limit the Agent's
rights in the Collateral or pursuant to the Financing Documents.

                                   ARTICLE XI

                         ASSIGNMENTS; MERGER OF ISSUER

     Notwithstanding anything in this Lease to the contrary, the Guarantor may
assign its rights and interests under this Lease and the other Operative
Documents and its rights and interests in the Project to any Person provided
that: (a) either (i) all amounts owed to the Banks under the Financing Documents
shall have been paid in full or (ii) such sale or assignment shall not
constitute a breach of the Financing Agreement or any Financing Documents which
has not been waived or consented to by the Agent; and (b) either (x) at the time
of such sale or assignment the Guarantor shall not be in default in the payment
of any amounts due to the Issuer under this Lease or the PILOT Agreement, or (y)
the Issuer shall have consented to such sale or assignment. Nothing in this
Lease shall prohibit the sale, assignment or encumbrance of all or

                                       39
<PAGE>

any portion of the Project or the Guarantor's interest therein pursuant to the
Financing Documents or the granting or creation of a Permitted Lien.

     The Issuer has pledged and assigned, pursuant to the terms of the
Mortgages, certain of its rights and interests in the Project and under and
pursuant to this Lease to the Agent on behalf of the Banks as security for the
payment of the principal of and interest on the Bonds. Such pledge and
assignment shall in no way impair or diminish any obligations of the Issuer
under this Lease. The Guarantor hereby acknowledges receipt of notice of, and
consents to, such pledge and assignment by the Issuer to the Agent on behalf of
the Banks and specifically agrees to perform for the benefit of the Agent on
behalf of the Banks all of its duties and undertakings hereunder.

     (a) Nothing contained in this Lease shall prevent the consolidation of the
Issuer with, or merger of the Issuer into, or assignment by the Issuer of its
rights and interests hereunder to any other body corporate and politic and
public instrumentality of the State of New York, or political subdivision
thereof, which has the legal authority to perform the obligations of the Issuer
hereunder, provided that upon any such consolidation, merger, or assignment, the
due and punctual performance and observance of all the agreements and conditions
of this Lease and the Mortgages to be kept and performed by the Issuer shall be
expressly assumed in writing by the public instrumentality or political
subdivision resulting from such consolidation or surviving such merger or to
which the Issuer's rights and interests hereunder shall be assigned.

                                       40
<PAGE>

     (b) As of the date of any such consolidation, merger, or assignment, the
Issuer shall give notice thereof in reasonable detail to the Guarantor and the
Agent. The Issuer shall promptly furnish to the Agent and the Guarantor such
additional information with respect to any such consolidation, merger, or
assignment as the Agent and the Guarantor may reasonably request.

     (a) During the term of this Lease, the Guarantor may not sublease the
Project, or any part thereof, without the prior written consent of the Issuer.
Notwithstanding the foregoing, the Guarantor may, without the Issuer's consent,
sublease portions of the Project in the ordinary course of its business,
provided that (i) no such lease shall relieve the Guarantor of its obligations
hereunder and (ii) the Guarantor shall, within 10 days after any such lease,
furnish the Issuer with a copy of the instruments effecting the same.

     (b) Notwithstanding anything to the contrary in this Lease, if in any
instance the Guarantor determines that any item of Equipment has become
inadequate, obsolete, worn out, unsuitable, undesirable, or unnecessary, the
Guarantor may remove such item of Equipment and may sell, trade in, exchange, or
otherwise dispose of the same, in whole or in part, without the prior written
consent of the Issuer, provided that such removal will not constitute an Event
of Default under the Financing Agreement. At the request of the Guarantor, the
Issuer shall execute and deliver to the Guarantor all instruments necessary or
appropriate to enable the Guarantor to sell or otherwise dispose of any such
item of Equipment, free from the Lien of the Financing Documents. The Guarantor
shall pay all costs, including reasonable attorneys' fees, incurred in
transferring title to, and releasing from the Lien of the Financing Documents,
any item of Equipment removed pursuant to this Section 11.4.

                                       41
<PAGE>

     (c) Nothing in this Section 11.4 shall restrict the right of the Guarantor
to sell or assign all or any portion of its interest in the Project or its
interest in this Lease to the extent such sale or assignment is permitted under
Section 11.1.

                                  ARTICLE XII

of Default under the Financing Agreement which is not waived by the Agent (or
the Banks or the Required Banks, as the case may be, if their consent is
required for such waiver under the terms of the Financing Agreement), and the
term "Default" shall mean an Inchoate Default.

     The Issuer may terminate this Lease in accordance with the provisions of
Section 6.3 hereof in the event that either (i) an Event of Default occurs and
is not cured within 60 days after written notice thereof from the Agent or the
Issuer to the Guarantor, or (ii) the Guarantor fails to pay any amount due to
the Issuer under this Lease within 60 days after written notice from the Issuer
that such amount is past due.

     In the event any agreement contained herein should be breached by the other
party and thereafter such breach be waived by the other party, such waiver shall
be limited to the particular breach so waived and shall not be deemed to waive
any other breach hereunder.

     The Table of Contents and the Section headings in this Lease have been
prepared for convenience of reference only and shall not control, affect the
meaning of, or be taken as an interpretation of any provision of this Lease.

     (a) The obligations and agreements of the Issuer contained herein and in
the other Financing Documents and in any other instrument or document executed
in connection herewith or therewith, and any instrument or document supplemental
hereto or thereto, shall be deemed the obligations and agreements of the Issuer
and not of any member, officer, agent (other than the Guarantor), or employee of
the Issuer in his individual capacity; and the members, officers, agents (other
than the Guarantor), and employees of the Issuer 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. The obligations and agreements of the Issuer contained herein
or therein shall not constitute or give rise to an obligation of the State of
New York or the County of Onondaga, and neither the State of New York nor the
County of Onondaga shall be liable hereon or thereon. 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
lease, sale, or other disposition of the Project, except for revenues derived by
the Issuer with respect to the Unassigned Rights. No order or decree of specific
performance with respect to any of the obligations of the Issuer hereunder or
thereunder shall be sought or enforced against the Issuer unless:

                                       46
<PAGE>

     (i) The party seeking such order or decree shall first have requested the
Issuer in writing to take the action sought in such order or decree of specific
performance, and ten days shall have elapsed from the date of receipt of such
request, and the Issuer 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) or failed to respond within such notice period; and

     (ii) If the Issuer refuses to comply with such request and the Issuer'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 Issuer an amount or undertaking sufficient to cover such
reasonable fees and expenses; and

     (iii)     If the Issuer refuses to comply with such request and the
Issuer's refusal to comply is based on its reasonable expectation that it or any
of its members, officers, agents (other than the Guarantor), or employees shall
be subject to potential liability, the party seeking such order or decree shall
(1) agree to indemnify and hold harmless the Issuer and its members, officers,
agents (other than the Guarantor), and employees against any liability incurred
as a result of its compliance with such demand; and (2) if requested by the
Issuer, furnish to the Issuer satisfactory security to protect the Issuer and
its members, officers, agents (other than the Guarantor), and employees against
all liability expected to be incurred as a result of compliance with such
request.

     (b) Any failure to provide notice, indemnity, or security to the Issuer
pursuant to this Section 13.10 shall not alter the full force and effect of any
Event of Default under this Lease.

     (c) Except to the extent otherwise expressly provided in Section
10.3(a)(7), the obligations and agreements of Guarantor contained herein and any
instrument or document supplemental hereto, shall be deemed the obligations and

limited solely to the assets of the Guarantor) and not of any partner, member,
beneficial owner, officer, agent, or employee of Guarantor in his or its
individual capacity, and the partners, members, beneficial owners, officers,
agents and employees of the Guarantor shall not be liable personally hereon or
be subject to any personal liability or accountability based upon or in respect
hereof or of any transaction contemplated hereby.

Guarantor hereunder are, and shall be, subject and subordinate to the Ground
Lease, the Liens of the Mortgages, and to any mortgage or mortgages, whether fee
or leasehold mortgages, which may now or hereafter affect the Project or the
land under the Project, and to all renewals, modifications, consolidations,
replacements, and extensions thereof, and advances thereunder. The subordination
of this Lease to the Ground Lease and Mortgages shall be automatic, without
execution of any further subordination agreement by the Guarantor. Nonetheless,
if the Agent or the Issuer requires a further written subordination agreement,
the Guarantor agrees to execute, acknowledge, and deliver the same.
