                              W I T N E S S E T H:

                                   ARTICLE 1
                       SALE OF PROPERTY; SALE OF INTERESTS

the form of EXHIBIT C. The transactions contemplated herein, including the
transfer of the Property to the Company and the transfer of the Interests to
Buyer, are referred to herein collectively as the "TRANSACTIONS". The Property

including all of Seller's right, title and interest in and to all rights-of-way,
open or proposed streets, alleys, easements, strips or gores of land adjacent

     .2 Personal Property. All tangible personal property owned by Seller
(excluding any computer software that either is licensed to Seller or Seller
deems proprietary or confidential), located on the Real Property and used in the
ownership, operation and maintenance of the Real Property and all
non-confidential books, records and files (excluding any internal appraisals,

Seller's property manager that Seller reasonably deems proprietary or
confidential) relating to the Real Property (herein collectively called the
"PERSONAL PROPERTY"); and

     .3 Other Property Rights. (a) Seller's interest as landlord in all leases
for tenants of the Real Property on the Closing Date (herein collectively called

and commission agreements, all equipment leases, and any additional service,
supply, maintenance or utility contracts entered into in accordance with the

Subsection 9.2.1, listed in EXHIBIT B), and (ii) to the extent that the same
have been obtained by Seller prior to the Closing, any licenses, permits and
other written authorizations necessary for the use, operation or ownership of
the Real Property or Personal Property (the rights and interests of Seller
described in Subsections 1.3(a) and (b), collectively the "OTHER PROPERTY
RIGHTS").

                                   ARTICLE 2
               PURCHASE PRICE AND ASSIGNMENT OF EXISTING MORTGAGE

     .2 Deposit Money. Upon the date of the full and final execution of this
Agreement (such date, the "CONTRACT DATE"), and as a condition precedent to the

     .4 [Intentionally Omitted].

     .5 Assignment of Existing Mortgage Loan; New Mortgage Loan.

          (a) Assignment of Existing Mortgage. Title to the Property is subject
to that certain mortgage dated March 30, 1990 (the "EXISTING MORTGAGE") and
related loan documents executed by Seller in favor of Asahi International Ltd.,
as assigned to 745 Property Investments (the "EXISTING LENDER") pursuant to that
certain Assignment of Mortgage and Security Agreement and the General Assignment
each dated as of March 1, 1999. At the Closing, the Company shall pay, or cause
to be paid, to Existing Lender an amount equal to the then outstanding principal
amount of the Existing Mortgage Loan (which at Closing shall be One Hundred
Twelve Million Dollars ($112,000,000)) in full consideration for an assignment
of the Existing Mortgage Loan described in this Subsection. Seller shall cause
Existing Lender to assign the Existing Mortgage and the related Promissory Note
(the "EXISTING NOTE") to the holder of the Mortgage Loan (as described below)
pursuant to the Assignment of Existing Note and Mortgage in the form of EXHIBIT
M. None of Seller, Existing Lender, any affiliate of Seller, any affiliate of
Existing Lender or the Company will be required to make any affidavits or
representations in respect of the Existing Mortgage or the assignment thereof
(other than with respect to the outstanding principal amount of the Existing
Mortgage and as set forth in Subsection 8.2.2(m)); it being agreed by Buyer and
Seller that Seller shall cause Existing Lender to assign the Existing Mortgage
without recourse, representation or warranty to the holder of the Mortgage Loan
on the Closing Date pursuant to the requirements in this Section 2.5.

          (b) New Mortgage Loan. Buyer and Seller, on behalf of the Company,
shall obtain part or all of the sums necessary to make the payment to Existing
Lender by obtaining first mortgage financing in an original principal amount not
less than One Hundred Ten Million Dollars ($110,000,000) and not more than One
Hundred Twenty Million Dollars ($120,000,000) from a life insurance company, a
money center bank, an investment bank (either directly or acting through its
loan origination subsidiary) or an equivalent institutional lender (any such
entity, an "APPROVED LENDER," the Approved Lender making the Mortgage Loan, the
"LENDER"), which loan shall (i) have a term of not less than seven (7) years,
(ii) bear a fixed rate of interest at the prevailing market rate for loans of
equivalent size and equivalent loan-to-value ratio, and (iii) be secured only by
a first mortgage lien on the Property and a related assignment of leases and
rents, fixture filings and a security agreement with respect to the Personal
Property (the "MORTGAGE LOAN"). Seller's consent to the Mortgage Loan shall be
conditioned upon obtaining the approval of the Investment Committee of
Prudential Real Estate Investors. The obligations under the related mortgage
loan documentation shall be non-recourse, other than recourse to the Company,
Buyer and/or Seller (and as to the Seller's liability, such liability will be
limited to the assets of PRISA) that may result from non-recourse carve-out
provisions customary for loans of a similar size and loan-to-value ratio;
provided that the liability to Buyer or Seller, as the case may be, pursuant to
such non-recourse carve-out provisions shall be several (it being understood and
agreed that each party shall be responsible for, and shall indemnify the other
from, all such costs, expenses and liabilities attributable to its actions or
omissions).

          (c) Costs. Except as otherwise expressly set forth in this Agreement,
the Company shall bear all reasonable costs and expenses associated with the
origination of the Mortgage Loan incurred by Buyer, Seller or their respective
predecessors in interest on or after October 5, 1999 (all such costs and
expenses, collectively, the "SHARED MORTGAGE LOAN EXPENSES"), including loan
application fees, commitment fees, all premiums and charges in connection with
the Lender's title insurance policy (including appropriate endorsements), the
costs of preparing or updating the survey, mortgage broker fees (not to exceed
an amount mutually satisfactory to Buyer and Seller), the costs associated with
any interest rate swap agreement, and any Excess Mortgage Recording Tax. Buyer
and Seller shall cooperate with all reasonable requests made by the other and
mutually satisfactory prospective lenders in arranging for the Mortgage Loan;
provided that neither Buyer nor Seller shall be under any obligation to provide
or disclose any proprietary, confidential or privileged information or assume or
incur any costs, expenses or liabilities in connection therewith (except as
expressly contemplated in this Subsection 2.5(c)).

          (d) Excess Loan Proceeds. The proceeds of the Mortgage Loan remaining
(such amount, the "EXCESS MORTGAGE LOAN PROCEEDS") after deduction of all sums
necessary to pay (i) the consideration due in respect of the assignment of the
Existing Mortgage Loan, (ii) all Shared Mortgage Loan Expenses, and (iii) all
other Shared Closing Costs, if any, shall be distributed by the Company as
follows: (A) 50.1% of the Excess Mortgage Loan Proceeds, representing Seller's
pro-rata share of the same, shall be paid to Seller, in cash by wire transfer of
immediately available funds to an account or accounts designated by Seller, and
(B) the balance, representing Buyer's pro-rata share of the same, shall be paid
to Buyer, in cash by wire transfer of immediately available funds to an account
or accounts designated by Buyer.

     .6 Mortgage Loan Contingency. The obligations of Buyer are conditioned upon
the issuance on or before January 14, 2000 (the "COMMITMENT DATE") of a written
commitment from an Approved Lender for the Mortgage Loan containing terms and
conditions mutually satisfactory to Buyer and Seller (the "MORTGAGE LOAN
COMMITMENT"). If the Mortgage Loan Commitment is not issued on or before the
Commitment Date, then Buyer may terminate this Agreement by giving written
notice thereof within two (2) Business Days after the Commitment Date, in which
case this Agreement shall be deemed terminated and thereafter, neither party
shall have any further rights against, or obligations or liabilities to, the
other except (a) that the Deposit shall be refunded to Buyer promptly and (b)
for obligations and liabilities stated in this Agreement to survive the
termination of this Agreement. If Buyer fails to give notice of termination not
later than two (2) Business Days after the Commitment Date, then Buyer shall be
deemed to have waived its right to terminate this Agreement and receive a return
of the Deposit by reason of the Contingency contained in this Section 2.6.

                                   ARTICLE 3
                                  TITLE MATTERS

     .1 Title to Real Property. Seller has previously delivered to Buyer (a) a
commitment to issue an Owner's Policy of Title Insurance with respect to the
Real Property issued by Chicago Title Insurance Company (the "TITLE COMPANY"),
identified as Title Insurance No. TA#99(01)479, a copy of which is attached
hereto as EXHIBIT D (the "TITLE REPORT"), (b) copies of all recorded documents
referred to on Schedule B of the Title Report as exceptions to coverage (the
"TITLE DOCUMENTS"), and (c) a survey of the Property prepared by
Harwood-Goldberg Surveying & Engineering Associates, P.C., dated February 15,
1989, updated by visual examination on March 9, 1990 and on May 27, 1999 (the
"SURVEY"). Buyer hereby confirms its receipt and approval of the Title Report,
the Title Documents and the Survey and shall cause the Company to similarly
approve the same at Closing.

     .2 Title Defects.

          .2.1 Definition of Permitted Exceptions. As used herein, the term
"PERMITTED EXCEPTIONS" shall mean and include all of the following: (a)
applicable zoning and building ordinances and land use regulations, (b) all
liens, encumbrances, covenants, conditions, restrictions, easements and other
matters of record except to the extent that the same are caused by the acts or
omissions of Seller and are placed of record after the expiration of the period
starting on October 5, 1999 and ending on the first to occur of (i) November 19,
1999 and (ii) the Contract Date (the "EXCLUSIVITY PERIOD"), the Existing
Mortgage, (c) such other exceptions to title as are listed on the marked copy of
Schedule B of the Title Report annexed hereto as EXHIBIT D, including (i) those
of the Title Company's standard printed exceptions not indicated as deleted in
EXHIBIT D, (ii) such state of facts as is disclosed in the Survey, (iii) such
state of facts as would be disclosed by a physical inspection of the Property,
(iv) the lien of taxes and assessments not yet due and payable (it being agreed
by Buyer and Seller that if any tax or assessment is levied or assessed with
respect to the Property after the date hereof and the owner of the Property has
the election to pay such tax or assessment either immediately or under a payment
plan with interest, Seller may elect to pay under a payment plan, which election
shall, subject to Section 5.2, be binding on the Company), (v) any exceptions to
title caused by Buyer, its agents, representatives or employees (provided,
however, that Buyer agrees for itself and its agents, representatives and
employees, that it shall not cause any exceptions to title without the prior
written approval of Seller), (vi) any exceptions to title caused by the Company
(as approved by Seller and Buyer), (vii) such other exceptions to title as the
Title Company shall commit to insure over without any additional cost to the
Company, whether such insurance is made available in consideration of payment,
bonding, indemnity of Seller or otherwise, and (viii) the rights of the tenants
under the Leases as tenants only, and (d) any matters deemed to constitute
additional Permitted Exceptions under Subsection 3.2.2. Notwithstanding any
provision to the contrary contained in this Agreement or any of the documents to
be executed in connection herewith or pursuant hereto, any or all of the
Permitted Exceptions may be omitted by Seller in the Deed without giving rise to
any liability of Seller, irrespective of any covenant or warranty of Seller
contained in the Deed (which provisions shall survive the Closing and not be
merged therein).

          .2.2 Certain Exceptions to Title. Buyer shall have the right, on
behalf of the Company to be formed, to object in writing to any title matters
that are not Permitted Exceptions and that materially adversely affect the
Company's title to the Real Property that may appear on supplemental title
reports or updates to the Title Report issued after the date hereof (herein
collectively called the "OTHER LIENS") within fifteen (15) days after receipt
thereof by Buyer. Unless Buyer shall timely object to such Other Liens, all such
Other Liens and any matters that do not materially adversely affect the
Company's title to the Real Property that are set forth in any such supplemental
reports or updates shall be deemed to constitute additional Permitted
Exceptions. Any exceptions that are timely objected to by Buyer shall be herein
collectively called the "TITLE OBJECTIONS". Seller may elect (but shall not be
obligated) to remove, or cause to be removed at its expense, any Title
Objections, and shall be entitled to a reasonable adjournment of the Closing
(not to exceed ninety (90) days) for the purpose of such removal, which removal
will be deemed effected by the issuance of title insurance eliminating or
insuring against the effect of the Title Objections. Seller shall notify Buyer
in writing within five (5) days after receipt of any Buyer's notice of the Title
Objections whether Seller elects to remove the same. If Seller is unable to
remove or endorse over any Title Objections prior to the Closing, or if Seller
elects not to remove one or more Title Objections, Buyer may elect to either (a)
terminate this Agreement, in which event the Deposit shall be returned to Buyer
and, thereafter, the parties shall have no further rights or obligations
hereunder except for obligations which expressly survive the termination of this
Agreement, or (b) waive such Title Objections, in which event such Title
Objections shall be deemed additional "PERMITTED EXCEPTIONS" and the Closing
shall occur as herein provided without any reduction of or credit against the
Purchase Price.

          .2.3 Discharge of Title Objections. If on the Closing Date there are
any Title Objections that Seller has elected to pay and discharge, Seller may
use any portion of the Purchase Price to satisfy the same, provided Seller shall
either deliver to the Company at the Closing instruments in recordable form and
sufficient to cause such Title Objections to be released of record, together
with the cost of recording or filing such instruments, or cause the Title
Company to insure over the same, without any additional cost to the Company,
whether such insurance is made available in consideration of payment, bonding,
indemnity of Seller or otherwise.

     .3 Title Insurance. At the Closing, the Title Company together with the
co-insurers named in the last sentence of this Section 3.3 shall issue to the
Company an ALTA title insurance policies in the form of the Title Report
(collectively, the "OWNER'S TITLE POLICY"), in the amount of $192,000,000.00,
insuring that fee simple title to the Real Property is vested in the Company
subject only to the Permitted Exceptions. Buyer shall be entitled to cause the
Company to request that the Title Company and the co-insurers provide such
endorsements (or amendments) to the Owner's Title Policy as Buyer may reasonably
require, provided that (a) such endorsements (or amendments) shall either (i) be
at no cost to, and shall impose no additional liability on, Seller or the
Company, or (ii) have been agreed to by Seller on behalf of the Company, (b)
Buyer's obligations under this Agreement shall not be conditioned upon the
Company's ability to obtain such endorsements and, if the Company is unable to
obtain such endorsements, Buyer shall nevertheless be obligated to proceed to
close the Transactions without reduction of or set off against the Purchase
Price, and (c) the Closing shall not be delayed as a result of Buyer's request
unless Seller shall have expressly consented to such delay. Title insurance
coverage shall be provided by (A) Chicago Title Insurance Company (through Title
Associates) in the amount of $96,000,000; (B) Lawyers Title Insurance
Corporation in the amount of $48,000,000; (C) First American Title Insurance
Company (NY) in the amount of $20,000,000; and (D) Fidelity National Title
Insurance Company of New York (through Royal Abstract) in the amount of
$28,000,000. Buyer's counsel shall be responsible for coordinating the efforts
of all co-insurers and Buyer shall cause such co-insurers to issue title
policies that are identical to the Title Policy issued by the Title Company, in
each case, with endorsements reasonably satisfactory to Seller coordinating such
title insurance coverage.

                                   ARTICLE 4
                 BUYER'S DUE DILIGENCE/CONDITION OF THE PROPERTY

     .1 Buyer's Inspections and Due Diligence. Buyer acknowledges that
commencing prior to the execution of this Agreement, Buyer has conducted its
examinations, inspections, testing, studies and/or investigations (herein
collectively called the "DUE DILIGENCE") of the Property being transferred to
the Company, the Existing Mortgage, information regarding the Property and such
documents in Seller's possession applicable to the Property, including the Title
Report, the Survey, the Title Documents, the Leases, the Contracts, the Property
Documents, the environmental reports listed on EXHIBIT E, and such other
non-proprietary, non-privileged reports, documents, books and records that
pertain to the Property being transferred to the Company as Buyer has deemed or
shall deem necessary or appropriate (all of the foregoing documents being herein
collectively called the "DOCUMENTS").

     .2 Buyer's Acknowledgement of Prior Due Diligence. (a) Buyer acknowledges
that Buyer (i) has already performed its due diligence inspection of the locale
and leasing market of the Property and (ii) is satisfied with the market
assumptions Buyer utilized in its analysis of the Property, the Company and
determination of the Purchase Price (such as assumptions with respect to rental
rates, leasing costs, vacancy and absorption rates, land values, replacement
costs, maintenance and operating costs, financing costs, ETC.).

     (b) Existing Mortgage Loan. Buyer acknowledges its receipt of copies of (i)
loan documents relating to the loan (the "EXISTING MORTGAGE LOAN") secured by
the Existing Mortgage, (ii) organizational documents of Existing Lender and
(iii) cancelled checks evidencing principal or interest payments heretofore made
by or on behalf of Seller in respect of the Existing Mortgage Loan (Clauses (i),
(ii) and (iii), collectively, the "MORTGAGE ASSIGNMENT DOCUMENTS").

     .3 Buyer's and Company's Certificate. The Company shall acquire the
Property and Buyer shall purchase the Interests in the Company (and thereby
acquire an indirect interest in the Property) "As Is", by relying on Buyer's
inspections and other due diligence activities and only those representations
and warranties of Seller set forth in Article 8. Buyer shall deliver to Seller
and shall cause the Company to deliver at the Closing, a certificate in the form
of EXHIBIT F, with respect to, among other things, the "As Is" nature of the

                                   ARTICLE 5
                           ADJUSTMENTS AND PRORATIONS

The following adjustments and prorations shall be made at the Closing:

     .1 Lease Rentals and Expenses.

          .1.1 Definition of "Rent". For purposes of this Article 5, the term
"RENT" shall mean all base rents, percentage rents, additional rent and any tax
and operating expense reimbursements and escalations due from the tenants under
the Leases.

          .1.2 Rents. All collected Rents shall be prorated between Seller and
the Company as of the day prior to the Closing Date. Seller shall be entitled to
all Rents attributable to any period to but not including the Closing Date. The
Company shall be entitled to all Rents attributable to any period on and after
the Closing Date. For purposes of determining each of the Company's and Seller's
PRO RATA share of percentage rents, tax and operating expense reimbursements and
escalations, the amount "attributable" to the period prior to the Closing Date
shall be equal to the aggregate amount of such Rents actually collected for the
calendar year (or lease years or other applicable accounting periods under the
leases) in which the Closing occurs multiplied by a fraction, the numerator of
which shall be the number of days prior to the Closing Date that the applicable
tenant leases space at the Real Property during the calendar year (or lease
years or other applicable accounting periods under the leases) in which the
Closing occurs and the denominator of which shall be 365. Except with respect to
percentage rents (which shall be prorated as provided below), Rents not
collected as of the Closing Date shall not be prorated at the time of the
Closing. With respect to percentage rent due from any tenant, Buyer and Seller
agree that at the Closing, estimated percentage rent shall be prorated for the
calendar year in which the Closing occurs as and when collected. After the
Closing, Buyer and Seller agree that the Company shall make a good faith effort
to collect any Rents not collected as of the Closing Date on Seller's behalf and
to tender the same to Seller upon receipt thereof (which obligation of the
Company shall survive the Closing and not be merged therein); provided, however,
that all Rents collected by the Company on or after the Closing Date shall first
be applied to all amounts due under the Leases at the time of collection (I.E.,
current rents and sums due the Company as the current owner and landlord) with
the balance (if any) payable to Seller, but only to the extent of amounts
delinquent and actually due to Seller. The Company shall not have an exclusive
right to collect the sums due to Seller under the Leases and Seller hereby
retains its rights to pursue any tenant under the Leases for sums due Seller for
periods attributable to Seller's ownership of the Real Property (including any
percentage rent that may be due with respect to any period of time prior to the
Closing, regardless of when the same is to be paid to the owner of the Real
Property pursuant to the terms of the applicable Lease); provided, however, that
Seller (a) shall be required to notify the Company in writing of its intention
to commence or pursue such legal proceedings; (b) shall only be permitted to
commence or pursue any legal proceedings after the date that is three (3) months
after the Closing; and (c) shall not be permitted to commence or pursue any
legal proceedings against any tenant seeking eviction of such tenant or the
termination of the underlying Lease. The terms of the immediately preceding
sentence shall survive the Closing and not be merged therein. The Company shall
receive a credit relating to the pre-paid rentals held by Seller, if any,
covering the period commencing on the Closing Date. Such amount shall be
distributed pursuant to the requirements of Section 5.5.

          .1.3 Reimbursable Lease Expenses. At the Closing, the Company shall
reimburse Seller for the Reimbursable Lease Expenses to the extent required by
the terms of Article 13. Such reimbursement shall be made pursuant to the
requirement of Section 5.5.

     .2 Real Estate Taxes. Real estate taxes shall be prorated on a cash basis
for the applicable tax year in which the Closing occurs. Such proration shall be
calculated based upon the actual number of days in such year, with Seller being
responsible for that portion of such year occurring prior to 11:59 p.m. of the
day prior to the Closing Date and the Company being responsible for that portion
of such year occurring thereafter. If the real estate tax rate and assessments
have not been set for the year in which the Closing occurs, then the proration
of such taxes shall be based upon the rate and assessments for the preceding
year, and such proration shall be adjusted between Seller and the Company upon
presentation of written evidence that the actual taxes paid for the year in
which the Closing occurs differ from the amounts used at the Closing and in
accordance with the provisions of Section 5.6. Seller shall pay all installments
of special assessments due and payable prior to the Closing Date and the Company
shall pay all installments of special assessments due and payable on and after
the Closing Date; provided, however, that Seller shall not be required by the
foregoing to pay any installments of special assessments that have not been
confirmed or that relate to projects that have not been completed on the date
hereof. Notwithstanding the foregoing terms of this Section 5.2, Seller shall
have no obligation to pay (and the Company shall not receive a credit at the
Closing for) any real estate taxes (except for special assessments) to the
extent that the Company is entitled after the Closing to reimbursement of such
taxes and assessments, or the recovery of any increase in taxes and assessments,
from the tenants under the Leases, regardless of whether the Company actually
collects such reimbursement or increased taxes and assessments from such
tenants, it being understood and agreed by Buyer and Seller that as among Buyer,
the Company and Seller, the Company shall be responsible for payment of all of
such real estate taxes and assessments, and the burden of collecting such
reimbursements shall be solely on the Company. If the Property has been assessed
for property tax purposes at such rates as would result in reassessment based
upon the change in land usage or ownership of the Property, the Company shall
pay all such taxes and Buyer hereby agrees, on behalf of the Company, to
indemnify and save Seller, as a seller (but not in its capacity as a member of
the Company), harmless from and against all claims and liability for such taxes.
Such indemnity shall survive the Closing and not be merged therein.

     .3 Other Property Operating Expenses. Operating expenses for the Property
shall be prorated as of 11:59 p.m. of the day prior to the Closing Date. Seller
shall pay all utility charges and other operating expenses attributable to the
Property to, but not including, the Closing Date (except for those utility
charges and operating expenses payable by tenants in accordance with the Leases)
and the Company shall pay all utility charges and other operating expenses
attributable to the Property on or after the Closing Date. To the extent that
the amount of actual consumption of any utility services is not determined prior
to the Closing Date, a proration shall be made at the Closing based on the last
available reading and post-Closing adjustments between the Company and Seller
shall be made within twenty (20) days of the date that actual consumption for
such pre-Closing period is determined, which obligation shall survive the
Closing and not be merged therein. Seller shall not assign to the Company any
deposits that Seller has with any of the utility services or companies servicing
the Property. The Company shall arrange with such services and companies to have
accounts opened in the Company's name beginning at 12:00 a.m. on the Closing
Date. Notwithstanding the foregoing terms of this Section 5.3, Seller shall have
no obligation to pay (and the Company shall not receive a credit at the Closing
for) any operating expenses to the extent that the Company is entitled after the
Closing to reimbursement of operating expenses, or the recovery of any increase
in operating expenses, from the tenants under the Leases, regardless of whether
the Company actually collects such reimbursement or increased operating expenses
from such tenants, it being understood and agreed by Buyer and Seller that as
between Buyer, the Company and Seller, the Company shall be responsible for
payment of all of such operating expenses, and the burden of collecting such
reimbursements shall be solely on the Company.

     .4 Closing Costs.

          (a) Shared Closing Costs. Buyer and Seller shall bear, on a pro rata
basis in accordance with their respective interests in the Company, (i) the
Shared Mortgage Loan Expenses, and, without duplication, (ii) all premiums and
customary charges in connection with the Owner's Title Policy (including the
costs of owner endorsements agreed upon by Buyer and Seller), (iii) all
recording and filing charges, (iv) all costs of complying with reasonable
requests for due diligence materials by mutually satisfactory prospective
lenders of the Mortgage Loan and otherwise cooperating with the conduct of such
lenders' due diligence (collectively, the "SHARED CLOSING COSTS"), (v) any
mortgage recording tax payable in respect of that portion of the principal
amount of the Mortgage Loan that is in excess of the principal amount of the
Existing Mortgage Loan outstanding as of the Closing Date (the "EXCESS MORTGAGE
RECORDING TAX"), (vi) the fees and costs of counsel to each of Seller and Buyer
directly attributable to the preparation and negotiation of the Operating
Agreement, and (vii) the fees and costs of counsel to each of Seller and Buyer
directly attributable to the negotiation of the Mortgage Loan with the Lender.
If the Closing does not occur, Buyer and Seller shall nonetheless be responsible
for payment of these Shared Closing Costs, with Seller bearing responsibility
for 50.1% of such total costs and Buyer bearing responsibility for 49.9% of such
total costs. If the Closing does not occur and Seller or its designee
nonetheless actually closes on the mortgage loan transaction to which Shared
Mortgage Loan Expenses relate, Seller shall reimburse Buyer for an amount equal
to that portion of Buyer's share of such Shared Mortgage Loan Expenses actually
paid by Buyer. The obligations of the parties under this Section 5.4 shall
survive the Closing (and not be merged therein) or any earlier termination of
this Agreement.

          (b) Buyer's Costs. Buyer shall pay (i) any mortgage recording tax
other than the Excess Mortgage Recording Tax, (ii) all costs of complying with
Seller's reasonable requests for due diligence materials with respect to SLG or
Buyer and otherwise cooperating with the conduct of Seller's Due Diligence
(Seller hereby confirming that it has completed such diligence), (iii) all costs
incurred by it or on its behalf in respect of Buyer's Due Diligence (Buyer
hereby confirming that it has completed such diligence), (iv) the costs of
endorsements to the "Owner's Title Policy" that were required by Buyer but were
not consented to by Seller, and (v) all fees and costs due to its counsel other
than fees directly attributable to negotiating the Mortgage Loan with the Lender
on behalf of the Company and the preparation and negotiation of the Operating
Agreement.

          (c) Seller's Costs. Seller shall pay (i) the brokerage commission due
to Cushman & Wakefield ("BROKER"), (ii) subject to Section 4.1 and Subsection
5.4(a), all costs of complying with reasonable Buyer's requests for due
diligence materials with respect to the Property, the Company or the Existing
Mortgage Loan and otherwise cooperating with the conduct of Buyer's Due
Diligence, (iii) all costs incurred by it or on its behalf in respect of
Seller's Due Diligence, (iv) all costs associated with obtaining estoppel
certificates from any Major Tenant or Other Tenant, (v) the costs of any real
property transfer taxes imposed by applicable taxing authorities in respect of
the transfer of the Property to the Company or the transfer of the Interests to
Buyer in accordance with the terms of this Agreement; provided that Seller's
aggregate liability in respect of such transfer taxes shall not exceed TWELVE
MILLION AND NO/100 DOLLARS ($12,000,000.00) and provided further that Seller's
payment obligation shall be limited to the assets of the PRISA account, (vi) all
fees and costs due its own counsel other than fees and costs directly
attributable to the negotiation of the Mortgage Loan with the Lender on behalf
of the Company and the preparation and negotiation of the Operating Agreement,
and (vii) all costs incurred in connection with causing the Title Company to
remove (y) any Title Objections to the extent Seller specifically agrees in
writing, at or prior to the Closing, to cause removal of such matter, it being
understood for purposes of this sentence that nothing in this Agreement or any
prior understanding or agreement of the parties shall be construed to obligate
Seller to so remove or agree to remove any such matter and (z) the matters
marked "omit" on Schedule B to EXHIBIT D.

     .5 Apportionment. If the apportionments, other credits or reimbursements to
be made at the Closing result in a net credit balance (a) to the Company, such
sum shall be paid at the Closing by Seller transferring funds in the amount of
such overall credit or reimbursement to the Company and the Company shall
distribute such funds at the Closing to its members in accordance with their
respective pro rata interests (i.e., with Seller receiving 50.1% of such amount
and Buyer receiving 49.9% of such amount), or (b) to Seller, such sums shall be
paid to Seller at the Closing by Seller wiring 50.1% of such amount on behalf of
the Company and Buyer wiring 49.9% of such amount on behalf of the Company, in
each case, in immediately available funds to the account or accounts to be
designated by Seller for the payment of the Purchase Price. Notwithstanding the
foregoing, Seller may, at Seller's option, deem payments to itself made by book
entry and shall not be obligated to actually wire funds.

     .6 Delayed Adjustment; Delivery of Operating and Other Financial
Statements. If at any time following the Closing Date, the amount of an item
listed in any section of this Article 5 shall prove to be incorrect (whether as
a result in an error in calculation or a lack of complete and accurate
information as of the Closing), the party in whose favor the error was made
shall promptly pay to the other party the sum necessary to correct such error
upon receipt of proof of such error, provided that such proof is delivered to
the party from whom payment is requested on or before one (1) year after the
Closing (such period being referred to herein as the "POST-CLOSING ADJUSTMENT
PERIOD"). In order to enable Seller and Buyer to determine whether any such
delayed adjustment is necessary, Buyer and Seller shall cause the Company to
provide to Seller and Buyer current operating and financial statements for the
Property no later than the date that is ninety (90) days prior to the expiration
of the Post-Closing Adjustment Period. The provisions of this Section 5.6 shall
survive the Closing and not be merged therein.

                                   ARTICLE 6

so-called "New York style" closing. Buyer and Seller shall conduct a

to convey title to the Property to the Company and to cause the Company to

comprising such tenant's lease are materially and substantively different than

deliver to the Company a representation letter with respect to such tenant in

accept such representation letter in lieu of an estoppel certificate from any
Major Tenant or in lieu of estoppel certificates from Other Tenants occupying,

Estoppel Language is obtained on or prior to the Closing. Seller shall, at the
request of Lender, forward agreements (collectively, the "SNDAS") concerning
subordination, non-disturbance or attornment of or by any tenant of the Property
with respect to Lender or Lender's rights with respect to the Mortgage Loan to
tenants and request that tenants execute such agreements. The delivery of (y)
any estoppel certificate containing language other than the Required Estoppel
Language or (z) any SNDAs shall not, however, under any circumstances be deemed
a condition precedent to Buyer's obligation to close the Transactions.

county or municipal statute, code, ordinance, law, rule or regulation ("LAW");

          (c) Buyer's Deliveries Complete. Buyer shall have delivered the funds
required hereunder and all of the documents and other items required pursuant to
Section 6.6 and shall have performed all other covenants, undertakings and
obligations, and complied with all conditions required by this Agreement, to be
performed or complied with by Buyer at or prior to the Closing; and

          (d) Existing Mortgage. The payment to Existing Lender as described in
Subsection 2.5(a) shall have been received.

     .2 Buyer's Obligations. Buyer's obligation to close the Transactions is
conditioned on all of the following, any or all of which
may be waived by Buyer by an express written waiver, at its sole option:

          (a) Representations True. Subject to the provisions of Section 8.3,
all representations and warranties made by Seller in this Agreement, as the same
may be amended as provided in Section 8.3, shall be true and correct in all
material respects on and as of the Closing Date, as if made on and as of such
date except to the extent that they expressly relate to an earlier date;

          (b) Title Conditions Satisfied. Subject to Section 10.1, at the time
of the Closing, title to the Real Property shall be as provided in Article 3 of
this Agreement; and

          (c) Seller's and Company's Deliveries Complete. Subject to Section
10.1, Seller and the Company shall have delivered all of the documents and other
items required pursuant to Sections 6.3, 6.4 and 6.5 (as the case may be) and
shall have performed all other covenants, undertakings and obligations, and
complied with all conditions required by this Agreement and all related
documents to be performed or complied with by Seller at or prior to the Closing.

     .3 Waiver of Failure of Conditions Precedent. At any time or times on or
before the date specified for the satisfaction of any condition, Seller or Buyer
may elect in writing to waive the benefit of any such condition set forth in
Section 7.1 or Section 7.2, respectively. By closing the Transactions, Buyer
shall be conclusively deemed to have waived the benefit of any remaining
unfulfilled conditions set forth in Section 7.2. In the event any of the
conditions set forth in Section 7.1 or Section 7.2 are neither waived nor
fulfilled, Seller or Buyer (as appropriate) may exercise such rights and
remedies as may be permitted by the terms of Article 10.

     .4 Approvals not a Condition to Buyer's Performance. Buyer acknowledges and
agrees that its obligation to perform under this Agreement is not contingent
upon Buyer's ability to obtain any (a) governmental or quasi-governmental
approval of changes or modifications in use or zoning or (b) modification of any
existing land use restriction.

                                   ARTICLE 8
                         REPRESENTATIONS AND WARRANTIES

validly existing and in good standing under the laws of its State of
organization and the State in which the Property is located, is authorized to
consummate the Transactions and fulfill all of its obligations hereunder and
under all documents contemplated hereunder to be executed or delivered by Buyer,
and has all necessary power to execute and deliver this Agreement and all
documents contemplated hereunder to be executed or delivered by Buyer, and to

duly authorized by all requisite partnership or corporate action on the part of
Buyer and are the valid and legally binding obligation of Buyer, enforceable in
accordance with their respective terms. Neither the execution and delivery of
this Agreement and all documents contemplated hereunder to be executed or
delivered by Buyer, nor the performance of the obligations of Buyer hereunder or
thereunder, will result in the violation of any applicable Law or any provision
of the agreement of partnership or articles of incorporation and by-laws of
Buyer or will conflict with any order or decree of any court or governmental
instrumentality of any nature by which Buyer is bound. Buyer is a single purpose
limited liability company whose sole member is SL Green Operating Partnership,
the sole general partner of which is SL Green Realty Corp. ("SLG").

          .1.2 Buyer's Financial Condition. No petition has been filed by or

validly existing and in good standing under the laws of its State of
organization and the State in which the Real Property is located, is authorized
to consummate the Transactions and fulfill all of its obligations hereunder and
under all documents contemplated hereunder to be executed by Seller, and has all
necessary power to execute and deliver this Agreement and all documents
contemplated hereunder to be executed by Seller and to perform its obligations
hereunder and thereunder. This Agreement and all documents contemplated
hereunder to be executed by Seller have been duly authorized by all requisite
corporate action on the part of Seller and are the valid and legally binding
obligation of Seller enforceable in accordance with their respective terms.
Neither the execution and delivery of this Agreement and all documents
contemplated hereunder to be executed by Seller, nor the performance of the
obligations of Seller hereunder or thereunder, will result in the violation of
any applicable Law or any provision of the articles of incorporation and by-laws
of Seller or will conflict with any order or decree of any court or governmental
instrumentality of any nature by which Seller is bound.

          .2.2 Seller's Other Representations. To Seller's knowledge (as defined
in Subsection 8.3.2):

          (a) Except as listed in EXHIBIT Q, Seller has not received any written
notice of any current or pending material actions, suits or equivalent

prohibit Seller from consummating the Transactions, or (iii) materially
adversely affect the continued use and enjoyment of the Property as an office
building. Seller shall give Buyer notice of any such action, suit or proceeding
that is filed prior to Closing of which Seller receives written notice, promptly
after Seller receives such written notice.

          (b) EXHIBIT B sets forth all effective service, supply, maintenance
and utility contracts relating to the Property and all deposits held by utility
companies with respect to the Property. As of the date of this Agreement, Seller
has not entered into any service, supply, maintenance or utility contracts
affecting the Property that will be binding upon the Company after the Closing
other than the contracts listed in EXHIBIT R.

          (c) Except for defaults cured on or before the date hereof, Seller has
not received any written notice of default under the terms of any of the
contracts except as listed in EXHIBIT Q.

          (d) Except for defaults cured on or before the date hereof or as
listed in EXHIBIT Q, Seller has not (i) given to any tenant a written notice of
default by such tenant under the terms of its Lease or (ii) received from any
tenant a written notice of default by the landlord under the terms of such
tenant's Lease.

          (e) As of the date of this Agreement, the only tenants of the Property
are the tenants listed in EXHIBIT S; provided, however, that the foregoing is
not intended (and shall not be construed) as representation by Seller of the
parties that are in actual possession of any portion of the Property since there
may be subtenants, licensees or assignees that are in possession of portions of
the Property of which Seller may not be aware.

          (f) Except as listed in EXHIBIT T, all tenant improvements of the
Property actually performed by Seller have been fully paid for by or on behalf
of Seller.

          (g) Except as listed in EXHIBIT U, there are no leasing brokerage

          (h) Except for violations cured or remedied on or before the date

Seller has not received any written notice from any governmental authority of
any violation of any zoning, building, fire, or health code, statute, ordinance,
rule or regulation applicable to the Property.

          (i) Except as set forth in EXHIBIT V, Seller has not commenced or

with respect to the Property.

          (k) As of the date of this Agreement, Seller has not received any

environmental laws.

          (l) Seller is not a party to any effective option to purchase, right
of first offer or right of first refusal to acquire all or any portion of the
Property or the Company.

          (m) The facts set forth in the Mortgage Assignment Documents were true
in all material respects as at the dates thereof.

          (n) Seller has not sold, transferred, pledged or encumbered any
interest in the Company since its formation other than a transfer of the
Interests to Buyer in accordance with this Agreement.

          (o) EXHIBIT S is a list of all effective leases for space in the
Property entered into by or on behalf of Seller, together with all amendments or
modifications thereto, as of the date of this Agreement. To the extent that
copies of leases, copies of other documents or any other information with
respect to the Property furnished or made available to or obtained by Buyer
prior to the Contract Date contains provisions or information that is
inconsistent with this representation and warranty or any information on EXHIBIT
S, such representation and warranty or information shall be deemed modified to
the extent necessary to eliminate the inconsistency and to conform such
representation and warranty or information to such lease, such documents or
other such information with respect to the Property. Without limiting the
foregoing, Seller shall have no liability for any representation or warranty
with respect to any lease for which (i) a Clean Estoppel has been delivered
covering the subject matter of such representation or warranty or (ii) any other
tenant estoppel certificate has been delivered prior to the Closing covering the
subject matter of such representation or warranty.

          .2.3 No Other Agreements. Seller has not entered into any currently
effective agreement to sell or dispose of all or any portion of its interest in
and to the Property (except for this Agreement and any options to purchase the
Property or a portion thereof that may be contained in any of the Leases).

     .3 General Provisions.

          .3.1 Representation as to Leases. Seller does not represent or warrant
that any particular Lease or Leases will be in force or effect on the Closing
Date or that the tenants will have performed their obligations thereunder.

          .3.2 Definition of "Seller's Knowledge". All references in this
Agreement to "Seller's Knowledge" or words of similar import shall refer only to
(a) material facts disclosed in writing by the existing property manager for the
Property in any final Manager's Closing Certificate (as described in Subsection
9.2.5), if received, and (b) the actual knowledge of Peter L. Ruggiero, Joseph
Cannon and William Anderson (herein collectively called the "DESIGNATED
EMPLOYEES") and shall not be construed to refer to the knowledge of any other
officer, agent or employee of Seller or any affiliate thereof or to impose or
have imposed upon the Designated Employees any duty to investigate the matters
to which such knowledge, or the absence thereof, pertains, including the
contents of the files, documents and materials made available to or disclosed to
Buyer or the contents of the files maintained by the Designated Employees. There
shall be no personal liability on the part of any of the Designated Employees
arising out of any representations or warranties made herein.

          .3.3 Seller's Representations Deemed Modified. To the extent that
Buyer knows or is deemed to know at or prior to the Closing that Seller's
representations and warranties are inaccurate, untrue or incorrect in any way,
such representations and warranties shall be deemed modified to reflect Buyer's
knowledge or deemed knowledge, as the case may be. For purposes of this
Agreement, Buyer shall be "deemed to know" of the existence of a fact or
circumstance to the extent that such fact or circumstance is disclosed by this
Agreement, the Documents, any estoppel certificate executed by any tenant of the
Real Property and delivered to Buyer, or any studies, tests, reports, or
analyses prepared by or for Buyer or any of its employees, agents,
representatives or attorneys (all of the foregoing being herein collectively
called the "BUYER'S REPRESENTATIVES") or otherwise obtained by Buyer or Buyer's
Representatives discloses such fact or circumstance; and Buyer shall be "deemed
to know" that a representation or warranty was untrue, inaccurate or incorrect
to the extent that this Agreement, any of the Documents, any estoppel
certificate executed by any tenant of the Property and delivered to the Company
or any Buyer's Representative, or otherwise obtained by Buyer or any Buyer's
Representative, contains information which is inconsistent with such
representation or warranty.

          .3.4 Notice of Breach; Seller's Right to Cure. If after the expiration
of the Exclusivity Period but prior to the Closing, Buyer or any Buyer's
Representative obtains actual knowledge that any of the representations or
warranties made herein by Seller are untrue, inaccurate or incorrect in any
material respect, Buyer shall give Seller written notice thereof within five (5)
Business Days of obtaining such knowledge (but, in any event, prior to the
Closing). If at or prior to the Closing, Seller obtains actual knowledge that
any of the representations or warranties made herein by Seller are untrue,
inaccurate or incorrect in any material respect (and prior to any deemed
modification thereof), Seller shall give Buyer written notice thereof within
five (5) Business Days of obtaining such knowledge (but, in any event, prior to
the Closing). In either such event, Seller shall have the right to cure such
misrepresentation or breach and shall be entitled to a reasonable adjournment of
the Closing (not to exceed ninety (90) days) for the purpose of such cure. If
Seller is unable or fails to so cure any such misrepresentation or breach of
warranty, then Buyer, as its sole remedy for any and all such materially untrue,
inaccurate or incorrect material representations or warranties, shall elect
either (a) to waive such misrepresentations or breaches of warranties and
consummate the Transactions without any reduction of or credit against the
Purchase Price, or (b) to terminate this Agreement by written notice given to
Seller on or prior to the Closing Date, as the Closing Date may have been
adjourned, in which event this Agreement shall be terminated, the Deposit shall
be returned to Buyer and, thereafter, neither party shall have any further
rights or obligations hereunder except as provided in any of this Agreement that
by its terms expressly provides that it survives the termination of this
Agreement. If any such representation or warranty is untrue, inaccurate or
incorrect, but is not untrue, inaccurate or incorrect in any material respect,
Buyer shall be deemed to have waived such misrepresentation or breach of
warranty, and Buyer shall be required to consummate the Transactions without any
reduction of or credit against the Purchase Price. The untruth, inaccuracy or
incorrectness of a representation or warranty shall be deemed material only if
Buyer's aggregate damages resulting from the untruth, inaccuracy or
incorrectness of the representations or warranties, taken together, are
reasonably estimated to exceed FIVE HUNDRED THOUSAND AND NO/100 DOLLARS
($500,000.00).

          .3.5 Survival; Limitation on Seller's Liability. The representations
and warranties made by Seller in Section 8.2 shall survive the Closing and not
be merged therein for a period of one hundred eighty (180) days after the date
of the Closing and Seller shall only be liable to Buyer hereunder for a
misrepresentation or breach of warranty made herein or in any of the documents
executed or delivered by Seller at or prior to the Closing with respect to which
a claim is made by Buyer against Seller on or before the one hundred eightieth
(180th) day after the date of the Closing. Anything in this Agreement to the
contrary notwithstanding, the maximum aggregate liability of Seller for Seller's
misrepresentations or breaches of warranties herein or in any documents executed
or delivered by Seller at or prior to the Closing (including, but not limited
to, any of Seller's representation letters delivered in lieu of tenant
estoppels) shall be limited as set forth in Section 14.16. Notwithstanding the
foregoing, however, if the Closing occurs, Buyer hereby expressly waives,
relinquishes and releases any right or remedy available to it at law, in equity
or under this Agreement to make a claim against Seller for damages that Buyer
may incur, or to rescind this Agreement and the Transaction, as the result of
any of Seller's representations or warranties being untrue, inaccurate or
incorrect if (a) Buyer knew or is deemed to know that such representation or
warranty was untrue, inaccurate or incorrect at the time of the Closing, or (b)
Buyer's damages as a result of all such representations or warranties being
untrue, inaccurate or incorrect, taken together, are reasonably estimated to
aggregate less than TWO HUNDRED FIFTY THOUSAND AND NO/100 DOLLARS ($250,000.00).

                                   ARTICLE 9
                                    COVENANTS

     .1 Buyer's Covenants. Buyer hereby covenants as follows:

          .1.1 Confidentiality. Buyer acknowledges that any information
heretofore or hereafter furnished to Buyer or Lender with respect to the
Company, the Interests or the Property has been and will be so furnished on the
condition that Buyer and Lender maintain the confidentiality thereof.
Accordingly, Buyer shall hold, and shall cause Lender and Buyer's and Lender's
respective directors, officers and other personnel and representatives to hold,
in strict confidence, and not at any time disclose to any other person or entity
without the prior written consent of Seller, any of the information in respect
of the Company, the Interests or the Property delivered to or for the benefit of
Buyer or Lender whether by agents, consultants, employees or representatives of
Buyer or Lender or by Seller or any of its agents, representatives or employees,
including any information heretofore or hereafter obtained by Buyer, Lender or
any of Buyer's Representatives in connection with any studies, inspections,
testings or analyses conducted by or for the benefit of Buyer or Lender as part
of Buyer's or Lender's due diligence, as the case may be. If the Closing does
not occur on or before the date specified in Section 6.1, or if negotiations
with respect to the Transactions are terminated, Buyer shall promptly return, or
cause to be returned, to Seller all copies of documents containing any of such
information without retaining any copy thereof or extract therefrom.
Notwithstanding anything to the contrary set forth above in this Subsection
9.1.1, but subject to the immediately following sentence, Buyer or Lender may
disclose such information on a need-to-know basis to their respective employees,
members of professional firms serving it or potential lenders, and as necessary
in order to comply with applicable laws and New York Stock Exchange Rules and
Regulations. Buyer and Seller, for themselves and their respective affiliates,
agree that any disclosure pursuant to this Subsection 9.1.1 or otherwise shall
(i) be consistent with the structure of the Transactions and exclude mention of
any of the terms of this Agreement or the Transactions or any other information
obtained during the course of Buyer's or Lender's due diligence that is not
required, by law or New York Stock Exchange Rules and Regulations, to be
disclosed, (ii) describe the overall form of the Transactions, and (iii) to the
fullest extent possible, must be pre-approved by Seller in writing. Buyer and
Seller agree that, notwithstanding any provision in this Agreement, the
Operating Agreement or any other agreement or document to the contrary, any
damages suffered by Seller for the failure of Buyer or Lender to comply with the
terms of this Subsection 9.1.1 shall be the responsibility of Buyer. By Buyer's
execution of this Agreement, Buyer hereby confirms its agreement to defend,
indemnify, and hold harmless Seller for all claims, damages and expenses
resulting from Buyer's or Lender's breach of this Subsection 9.1.1.

          .1.2 Buyer's Indemnity; Delivery of Reports. Buyer hereby agrees to
indemnify, defend, and hold Seller, its counsel, Broker, its sales agents or any
partner, officer, director, employee, agent or attorney of Seller, its counsel,
Broker or its sales agents or any other party related in any way to the
foregoing (all of which parties are herein collectively called the "SELLER
PARTIES") free and harmless from and against any and all costs, loss, damages
and expenses, of any kind or nature whatsoever (including attorneys fees and
costs), arising out of or resulting from the breach of the terms of Subsection
9.1.1 or the entry and/or the conduct of activities upon the Real Property by
Buyer or any Buyer's Representative in connection with the inspections,
examinations, testings and investigations of the Property conducted at any time
prior to the Closing, which indemnity shall survive the Closing (and not be
merged therein) or any earlier termination of this Agreement. Buyer shall
deliver promptly to Seller copies of all third party reports commissioned by or
on behalf of Buyer evidencing the results of tests, studies or inspections of
the Property.

          .1.3 Limit on Government Contacts. Notwithstanding any provision in
this Agreement to the contrary, except in connection with the preparation of a
so-called "Phase I" environmental report with respect to the Real Property,
Buyer shall not contact any governmental official or representative regarding
the environmental condition of the Real Property without Seller's prior written
consent thereto, which consent shall not be unreasonably withheld or delayed. In
addition, if Seller's consent is obtained by Buyer, Seller shall be entitled to
receive at least five (5) days' prior written notice of the intended contact and
to have a representative present when Buyer has any such contact with any
governmental official or representative.

          .1.4 Managing Agent; Collective Bargaining Agreement Obligations. As
of the Closing Date, the Company will enter into a leasing and management
agreement with S.L. Green Management Corp. ("MANAGER"), an affiliate of Buyer,
to lease, operate and manage the Property in the form of EXHIBIT W (the
"MANAGEMENT AGREEMENT"). Any employees at the Real Property who are subject to
any collective bargaining agreement and such collective bargaining agreements
are listed on EXHIBIT X. To the extent any collective bargaining agreement has
been terminated or cancelled in connection with the Transactions, the Company
may, but shall not be obligated to, cause the Manager to offer employment to,
and hire any or all employees formerly covered by, such terminated collective
bargaining agreement. At Closing, Buyer shall, and shall cause SLG and Manager
to, indemnify, defend and hold Seller free and harmless from and against any and
all liability, claims, actions, damages, judgments, penalties, costs and
expenses, including reasonable attorney's fees, accruing under or with respect
to the agreements listed on EXHIBIT X after the date of the Closing to the
extent such liabilities, claims, actions, damages, judgments, penalties, costs
and expenses are related to actions taken, or omitted to be taken, by Buyer, the
Company or Manager. Further, Buyer shall, and shall cause SLG and Manager to,
indemnify, defend and hold Seller free and harmless from and against any and all
liability, claims, actions, damages, judgments, penalties and expenses,
including reasonable attorney's fees, arising out of any claim that Buyer, the
Company or Manager shall have failed to adopt and/or assume any collective
bargaining agreement and/or shall have failed to offer employment to all
employees covered by such agreements, including any claims for termination pay;
provided that the Company shall reimburse Buyer, SLG and/or Manager, as the case
may be, an amount equal to ordinary and customary termination pay given to
employees to whom employment was not offered. Buyer and Seller acknowledge that
the agreement with Pritchard Industries automatically terminates in accordance
with its terms at Closing. If Buyer and Seller mutually determine that written
notice must be made to Pritchard Industries to effect or to confirm termination,
Buyer and Seller shall cause an appropriate notice, in form and substance
mutually satisfactory to Buyer and Seller, to be made to Pritchard Industries.

          .1.5 Contacting Labor Unions. Prior to the Closing, Buyer shall not
contact any official, representative or member of any labor union concerning the
Property without Seller's prior written consent, which consent may be granted or
withheld in Seller's sole discretion.

          9.1.6 Survival. The provisions of Section 9.1 shall survive the
Closing or the earlier termination of this Agreement.

     .2 Seller's Covenants. Seller hereby covenants as follows:

          .2.1 Service Contracts. From and after the date hereof and until the
first to occur of (i) the termination of this Agreement or (ii) the Closing
Date, Seller will not enter into, extend, renew, replace or modify any Contract
affecting all or a portion of the Property without the prior written consent of
Buyer, which consent will not be unreasonably withheld, conditioned or delayed.
Seller shall furnish Buyer with a written notice of the proposed action, which
shall contain information regarding the proposed action Seller believes is
reasonably necessary to enable Buyer to make informed decisions with respect to
the advisability of the proposed action. Any notice from Buyer rejecting the
proposed action shall include a description of the reasons for Buyer's
rejection. The foregoing consent requirement will not apply to any Contract
entered into in the ordinary course of business (as extended, renewed, replaced
or modified in the ordinary course of business) that can be terminated by the
owner of the Property without penalty on not more than thirty (30) days' notice.

          .2.2 Maintenance of Property. Except to the extent Seller is relieved
of such obligations by Article 11 and except with respect to facade maintenance
and/or remediation (which shall be performed in accordance with Section 9.2.6),
between the date hereof and the Closing Date, Seller shall maintain and keep the
Property in a manner consistent with Seller's past practices with respect to the
Property; provided, however, that Buyer hereby agrees that the Company shall
accept the Property subject to, and Seller shall have no obligation to cure, any
violations of Laws, and any physical conditions that would give rise to
violations, that exist on the last day of the Exclusivity Period or that arise
between the last day of the Exclusivity Period and the Closing Date. Between the
date hereof and the Closing Date, Seller will promptly advise Buyer of any
written notice Seller receives after the date hereof from any governmental
authority of the violation of any Laws regulating the condition or use of the
Property.

          .2.3 Access to Property. Between the date hereof and the Closing Date
(such period the "CONTRACT PERIOD"), Seller shall allow Buyer or Buyer's
Representatives access to the Property upon reasonable prior notice at
reasonable times provided (a) such access does not interfere with the rights of
tenants or otherwise unreasonably interfere with the operation of the Property;
(b) Buyer shall not contact any tenant without Seller's prior written consent,
which shall not be unreasonably withheld or delayed; (c) Seller or its
designated representative shall have the right to pre-approve (which approval
shall not be unreasonably withheld or delayed) and be present during any
physical testing of the Property; and (d) Buyer shall return the Property to the
condition existing prior to such tests and inspections. Prior to such time as
Buyer or any Buyer's Representative enters the Real Property, Buyer shall obtain
policies of general liability insurance which insure Buyer, its agents and
representatives with liability insurance limits of not less than ONE MILLION AND
NO/100 DOLLARS ($1,000,000.00) combined single limit for personal injury and
property damage and name Seller and the managing agent of the Real Property as
additional insureds and which are with such insurance companies, provide such
coverages and carry such other limits as Seller shall reasonably require, and
provide Seller with certificates of insurance evidencing that Buyer has obtained
the aforementioned policies of insurance. Buyer hereby agrees that no
information obtained pursuant to the foregoing or any additional investigations
performed during the Contract Period shall (i) entitle Buyer to any adjustment
in the Purchase Price or (ii) create any additional conditions precedent to
Buyer's obligations to perform under this Agreement. The provisions of this
Subsection 9.2.3 shall survive the Closing or any earlier termination of this
Agreement.

          .2.4 Confidentiality. (a) To the extent Buyer provides to Seller
information not available to the public in respect of Buyer and/or SLG, then as
long as such information continues to be non-public information, Seller shall
hold, and shall cause its directors, officers and other personnel and
representatives to hold any such information, in strict confidence, and not
disclose to any other person or entity (other than (i) investors in any separate
account for whose benefit Seller's interest in the Company is to be held or any
advisory council or other similar body or (ii) counsel, accountants and advisors
such party deems necessary, and only to the extent such investors, advisory
council (including Prudential's Investment Management Committee) or other
similar body, counsel, accountants and advisors agree to keep the same strictly
confidential) without the prior written consent of Buyer, which consent shall
not be unreasonably withheld or delayed. If the Closing does not occur, Seller
shall promptly return to Buyer all copies of documents containing any of such
information without retaining any copy thereof or extract therefrom.
Notwithstanding anything to the contrary set forth in this Subsection 9.2.4,
Seller may disclose such information on a need-to-know basis to its employees,
members of professional firms serving it or potential lenders, and as any
governmental agency may require in order to comply with applicable laws. Seller
hereby confirms its agreement to defend, indemnify, and hold harmless Buyer for
all claims, damages and expenses resulting from Seller's breach of this
Subsection 9.2.4. The provisions of this Subsection 9.2.4 shall survive the
Closing or any earlier termination of this Agreement.

          (b) Seller is aware, and agrees to inform all persons to whom Seller
provides such non-public information, that the United States securities laws
prohibit any person who has received, from an issuer, material, non-public
information such as the information in question, from purchasing or selling the
securities of such issuer or from communicating such information to any other
person under circumstances in which it is reasonably foreseeable that such
person is likely to purchase or sell such securities.

          9.2.5 Property Manager's Closing Certificate; Property Manager
Termination. (a) Seller shall request that the existing property manager of the
Property provide to Seller prior to the Closing a certificate certifying as to
the matters described in Subsection 8.2.2 to the extent appropriate. If Seller
receives an executed version of such a certificate from the property manager (as
the same may be amended or modified by the property manager, the "MANAGER'S
CLOSING CERTIFICATE"), Seller shall deliver a copy of the same to Buyer promptly
after receipt of the same. Buyer acknowledges and agrees that neither Buyer nor
the Company shall be entitled to rely on the Manager's Closing Certificate and
that a copy of the same will be provided to Buyer, if received, for
informational purposes only.

          (b) Seller shall cause the termination of the agreement with the
existing manager of the Property effective as of the Closing Date.

          9.2.6 Facade Remediation. (a) Prior to Closing, Buyer and Seller shall
jointly (i) determine the scope and extent of all facade remediation work, if
any, necessary so that the Property complies with so-called "Local Law 10" and
"Local Law 11" of The City of New York, (ii) determine a plan of action with
respect to the general scope of facade remediation, including a budget for
effectuating such plan, (iii) notwithstanding anything in the Management
Agreement to the contrary, hire the architect, project engineer and contractors
to effectuate such plan pursuant to agreements mutually satisfactory to Seller
and Buyer, and (iv) in connection therewith, approve plans and specifications,
drawings and all change orders. Seller shall be responsible for the costs of all
such facade remediation work in accordance with the provisions of the approved
contracts.

          (b) If Buyer and Seller are not able to agree as to any matter
referred to in Subsection 9.2.6(a), either Buyer or Seller may submit the issue
to arbitration in New York, New York in accordance with the Commercial
Arbitration Rules or other appropriate rules of the American Arbitration
Association ("AAA"). The laws of the State of New York shall be deemed to apply
and control in such arbitration. If the AAA is not then in existence or does not
desire to act, then either party may apply to a New York court having
jurisdiction for the appointment of an arbitrator to hear the parties and
determine the matter. Provided the rules and regulations of the AAA or the
court, as the case may be, so permit, the AAA or such court shall select a
single arbitrator within five (5) Business Days after such submissions or
application, the arbitration shall commence five (5) Business Days thereafter
and, if necessary, shall be conducted for at least seven (7) hours on each
Business Day thereafter until completion. Neither Buyer nor Seller shall have
more than a total of seven (7) hours to present its case and to cross-examine or
interrogate Persons supplying information or documentation on behalf of the
other party, and the arbitrator shall render a decision (including an award of
costs to the prevailing party) within ten (10) days after conclusion of the
arbitration, which will be final and conclusive upon both parties. Judgment upon
the award rendered by the arbitrator may be entered in any court having
jurisdiction thereof. The parties submit to the IN PERSONAM jurisdiction and
venue of the United States District Court for the Southern District of New York
and the Supreme Court of the State of New York, New York County for the purpose
of confirming any such award and entering judgment thereon.

          9.2.7 Limited Guaranty Agreement of Rent Payments. Seller shall
guaranty, in favor of the Company and solely in respect of Suites 2100, 2400,
and 3601 of the Property, the receipt of not less than ONE MILLION AND NO/100
DOLLARS ($1,000,000.00) in total gross rent payments (without reference to
so-called "pass-throughs" or "reimbursables") during the one year period
commencing on the Closing Date. The guaranty shall be substantially in the form
of EXHIBIT Z (the "LIMITED GUARANTY AGREEMENT") and shall not be construed under
any circumstances to be an assumption by Seller of any obligation with respect
to reimbursable expenses, tenant improvement allowances, tenant work and the
like (it being understood and agreed that such reimbursable expenses and capital
costs shall be the costs of the Company). Amounts paid by Seller pursuant to
this guaranty shall be net of all gross rent payments (without reference to
so-called "pass-throughs" or "reimbursables") actually received by the Company
with respect to such suites during such period. Notwithstanding the foregoing,
Buyer and Seller agree that sixty percent (60%) of the aggregate amount actually
paid by Seller to the Company pursuant to the Limited Guaranty Agreement shall
be reimbursed by the Company to Seller, without interest, (a) in equal monthly
installments over an 18-month period, commencing on the first day of the first
month after the month in which the third (3rd) anniversary of the Closing Date
occurs; or (b) on any earlier date on which the Property or the Interests are
transferred. The obligations of Seller under this Subsection 9.2.7 shall survive
the Closing and shall not be merged therein.

     .3 Mutual Covenants.

          .3.1 Publicity. Seller and Buyer each hereby covenants that prior to
the Closing neither Buyer nor Seller shall issue any press release or public
statement (a "RELEASE") with respect to the Transactions without the prior
written consent of the other except to the extent required by law and New York
Stock Exchange Rules and Regulations. After the Closing, any Release issued by
either Buyer or Seller or their respective affiliates shall be subject to the
prior review and approval of the other party (not be unreasonably withheld,
conditioned or delayed), except to the extent required by law and New York Stock
Exchange Rules and Regulations. Notwithstanding anything to the contrary
contained in this Subsection 9.3.1, Buyer and Seller, for themselves and their
respective affiliates, agree that any Release issued pursuant to this Subsection
9.3.1 shall, if applicable, (i) be consistent with the structure of the
Transactions and exclude mention of any of the terms of this Agreement or the
Transactions that is not required, by law or New York Stock Exchange Rules and
Regulations, to be disclosed, (ii) describe the overall form of the
Transactions, and (iii) to the fullest extent possible, must be pre-approved by
the other party in writing (not to be unreasonably withheld or delayed). Buyer
and Seller agree that, notwithstanding any provision in this letter, the
Agreement, the Operating Agreement or any other agreement or document to the
contrary, any damages suffered by Buyer or Seller for the failure of the other
party to comply with the terms of this Subsection 9.3.1 shall be the
responsibility of the breaching party.

          .3.2 Broker. Seller shall pay a brokerage commission due in connection
with the Transactions to Broker pursuant to a separate agreement, and Buyer
shall be responsible for commissions or other fees of any other brokers with
whom it has dealt. Seller agrees to hold Buyer harmless and indemnify Buyer from
and against any and all damages, costs or expenses (including reasonable
attorneys' fees and disbursements) suffered by Buyer as a result of any claims
by any party claiming to have represented Seller as broker in connection with
the Transactions. Buyer agrees to hold Seller harmless and indemnify Seller from
and against any and all damages, costs or expenses (including reasonable
attorneys' fees and disbursements) suffered by Seller as a result of any claims
by any party claiming to have represented Buyer as broker in connection with the
Transactions.

          .3.3 Tax and Accounting Information. Buyer and Seller agree, for
themselves and their respective affiliates, to maintain and apply at all times
consistent and uniform practices and procedures with respect to any tax or
accounting matters relating to the Transactions or the interests in the Company.
Any disclosure by Buyer, Seller or any of their respective affiliates of any tax
or accounting information relating to the Transactions or the interests in the
Company (whether disclosed pursuant to, or as part of, a filing of any tax
returns, financial statements or other documents with a government agency, the
New York Stock Exchange or otherwise) (the "TAX AND ACCOUNTING INFORMATION")
shall be subject to the prior review and approval of the other party, except to
the extent required by law and New York Stock Exchange Rules and Regulations.
Notwithstanding anything to the contrary contained in this Subsection 9.3.3,
Buyer and Seller agree, for themselves and their respective affiliates, that any
disclosure of Tax and Accounting Information shall, if applicable, (a) be
consistent with the structure of the Transactions and exclude mention of any of
the terms of this Agreement or the Transactions that is not required, by law or
New York Stock Exchange Rules and Regulations, to be disclosed, and (b) to the
fullest extent possible, must be pre-approved by the other party in writing.
Buyer and Seller agree that, notwithstanding any provision in this Agreement,
the Operating Agreement or any other agreement or document to the contrary, any
damages suffered by any party for the failure of the other party to comply with
the terms of this Subsection 9.3.3 shall be the responsibility of the party that
has breached the terms hereof.

          .3.4 Tax Protests; Tax Refunds and Credits. Seller shall have the
right to continue and to control the progress of and to make all decisions with
respect to any contest of the real estate taxes for the Property due and payable
for the applicable tax year in which the Closing occurs and all prior tax years.
The Company shall have the right to control the progress of and to make all
decisions with respect to any contest of the real estate taxes for the Property
due and payable for all tax years subsequent to the tax year in which the
Closing occurs. All real estate tax refunds and credits received after the
Closing with respect to the Property shall be applied in the following order of
priority: first, to pay the costs and expenses (including attorneys' fees and
disbursements) incurred in connection with obtaining such tax refund or credit;
second, to pay any amounts due to any past or present tenant of the Real
Property as a result of such tax refund or credit to the extent required
pursuant to the terms of the Leases; and third, apportioned between the Company
and Seller as follows:

          (a) with respect to any refunds or credits attributable to real estate
taxes due and payable in the tax year in which the Closing occurs (regardless of
the tax year for which such taxes are assessed), such refunds and credits shall
be apportioned between the Company and Seller in proportion to the number of
days in such tax year that each party owned the Property (with title to the
Property being deemed to have passed as of 12:01 a.m. on the Closing Date);

          (b) with respect to any refunds or credits attributable to real estate
taxes due and payable during any period prior to the tax year in which the
Closing occurs (regardless of the tax year for which such taxes are assessed),
Seller shall be entitled to the entire refunds and credits; and

          (c) with respect to any refunds or credits attributable to real estate
taxes due and payable during any period after the tax year in which the Closing
occurs (regardless of the tax year for which such taxes are assessed), the
Company shall be entitled to the entire refunds and credits.

          .3.5 Survival. The provisions of this Section 9.3 shall survive the
Closing (and not be merged therein) or earlier termination of this Agreement for
a period equal to the longer of ten (10) years or the duration of the Company.

                                   ARTICLE 10
                              FAILURE OF CONDITIONS

     .1 To Seller's Obligations. If, on or prior to the Closing Date, (a) Buyer
is in default of any of its obligations hereunder, or (b) any of Buyer's
representations or warranties is untrue, inaccurate or incorrect in any material
respect, or (c) the Closing otherwise fails to occur by reason of Buyer's
failure or refusal to perform its obligations hereunder in a prompt and timely
manner, then Seller may elect to either (i) terminate this Agreement by written
notice to Buyer; or (ii) proceed to close the Transactions. Seller's failure to
either (A) form the Company or (B) transfer the Property to the Company shall
not constitute a failure of condition precedent under this Agreement, if Seller
notified Buyer in writing that Buyer has failed a condition precedent to Buyer's
obligations under this Agreement, which condition had not theretofore been
satisfied or waived, and as a consequence thereof, Seller was not prepared
either to form the Company or to transfer the Property thereto. If this
Agreement is so terminated, then Seller shall be entitled to the Deposit and may
request that Escrow Agent deliver the Deposit to Seller pursuant to the terms of
Article 12, whether held as cash or as a letter of credit, as liquidated
damages, and thereafter neither party to this Agreement shall have any further
rights or obligations hereunder other than any arising under any Section herein
which expressly provides that it survives the termination of this Agreement.

     .2 To Buyer's Obligations. If, at the Closing, (a) Seller is in default of
any of its obligations hereunder, or (b) any of Seller's representations or
warranties are untrue, inaccurate or incorrect in any material respect, or (c)
the Closing otherwise fails to occur by reason of Seller's failure or refusal to
perform its obligations hereunder in a prompt and timely manner, then Buyer
shall have the right, to elect, as its sole and exclusive remedy, to (i)
terminate this Agreement by written notice to Seller, promptly after which the
Deposit shall be returned to Buyer, or (ii) waive the condition and proceed to
close the Transactions, or (iii) seek specific performance of this Agreement by
Seller. As a condition precedent to Buyer exercising any right it may have to
bring an action for specific performance hereunder, Buyer must commence such an
action within ninety (90) days after the occurrence of Seller's default. Buyer
agrees that its failure to timely commence such an action for specific
performance within such ninety (90) day period shall be deemed a waiver by it of
its right to commence an action for specific performance as well as a waiver by
it of any right it may have to file or record a notice of LIS PENDENS or notice
of pendency of action or similar notice against any portion of the Real
Property.

                                   ARTICLE 11
                              CONDEMNATION/CASUALTY

     .1 Condemnation.

          .1.1 Right to Terminate. If, prior to the Closing Date, all or any
significant portion (as hereinafter defined) of the Real Property is taken by
eminent domain (or is the subject of a pending taking which has not yet been
consummated), Seller shall notify Buyer in writing of such fact promptly after
obtaining actual knowledge thereof, and, thereafter, either Buyer or Seller
shall have the right, at its respective election, to terminate this Agreement by
giving written notice to the other no later than ten (10) days after the giving
of Seller's notice, and the Closing Date shall be extended, if necessary, to
provide sufficient time for Buyer or Seller to make such election. The failure
by Buyer and Seller to so elect in writing to terminate this Agreement within
such ten (10) day period shall be deemed an election not to terminate this
Agreement. For purposes hereof, a "SIGNIFICANT PORTION" of the Real Property
shall mean such a portion as shall have a value, as reasonably determined by
Seller, in excess of FIVE MILLION AND NO/100 DOLLARS ($5,000,000.00). If either
party elects to terminate this Agreement as aforesaid, the provisions of Section
11.4 shall apply.

          .1.2 Assignment of Proceeds. If (a) neither Seller nor Buyer elects to
terminate this Agreement as provided for in Subsection 11.1.1 hereof, or (b) a
portion of the Real Property not constituting a significant portion of the Real
Property is taken or becomes subject to a pending taking, by eminent domain,
there shall be no abatement of the Purchase Price; provided, however, that, at
the Closing, Seller shall pay to the Company the amount of any award for or
other proceeds on account of such taking which have been actually paid to Seller
on or prior to the Closing Date as a result of such taking (less all costs and
expenses, including reasonable attorneys' fees and disbursements, incurred by
Seller as of the Closing Date in obtaining payment of such award or proceeds)
and, to the extent such award or proceeds have not been paid, Seller shall
assign to the Company at the Closing (without recourse to Seller) the rights of
Seller to, and the Company shall be entitled to receive and retain, all awards
for the taking of the Real Property or such portion thereof.

     .2 Destruction or Damage. If any of the Property is damaged or destroyed
prior to the Closing Date, Seller shall notify Buyer in writing of such fact
promptly after obtaining actual knowledge thereof. If any such damage or
destruction (a) is an insured casualty and (b) would cost less than FIVE MILLION
AND NO/100 DOLLARS ($5,000,000.00) to repair or restore, then this Agreement
shall remain in full force and effect and Buyer shall acquire the Interests upon
the terms and conditions set forth herein. In such event, Seller shall pay to
the Company at Closing an amount equal to the deductible applicable under
Seller's casualty policy, less all costs and expenses, including reasonable
attorneys' fees and disbursements, incurred by Seller as of the Closing Date in
connection with the negotiation and/or settlement of the casualty claim with the
insurer (the "REALIZATION COSTS"), and Seller shall assign to the Company all of
Seller's right, title and interest in and to all proceeds of insurance on
account of such damage or destruction. If the Property is damaged or destroyed
prior to the Closing Date and the cost of repair would equal or exceed FIVE
MILLION AND NO/100 DOLLARS ($5,000,000.00) or the casualty is an uninsured
casualty, then, notwithstanding anything to the contrary set forth above in this
Section 11.2, either Buyer or Seller shall have the right, at its respective
election, to terminate this Agreement. Buyer and Seller shall have thirty (30)
days after Seller notifies Buyer that such a casualty has occurred to make such
election by delivery to the other of a written election notice (the "ELECTION
NOTICE") and the Closing Date shall be extended, if necessary, to provide
sufficient time for Buyer or Seller to make such election. The failure by Buyer
and Seller to deliver the Election Notice within such thirty (30) day period
shall be deemed an election not to terminate this Agreement. If neither party
elects to terminate this Agreement as set forth above, this Agreement shall
remain in full force and effect, Seller shall assign to Buyer all of Seller's
right, title and interest in and to any and all proceeds of insurance on account
of such damage or destruction, if any, and, if the casualty was an insured
casualty, Seller shall pay the Company at Closing an amount equal to the
deductible (less the Realization Costs) under Seller's casualty insurance policy
(it being understood that the Company shall be responsible for any such
deductible thereafter).

     .3 Insurance. Seller shall maintain the property insurance coverage
currently in effect for the Property through the Closing Date.

     .4 Effect of Termination. If this Agreement is terminated pursuant to
Section 11.1 or Section 11.2, the Deposit shall be returned to Buyer. Upon such
refund, this Agreement shall terminate and neither party to this Agreement shall
have any further rights or obligations hereunder other than any arising under
any Section herein which expressly provides that it survives the termination of
this Agreement.

     .5 Waiver. The provisions of this Article 11 supersede the provisions of
any applicable Laws with respect to the subject matter of this Article 11.

                                   ARTICLE 12
                                     ESCROW

     .1 Escrow Deposits. The Deposit and any other sums that the parties agree
shall be held in escrow (herein collectively called the "ESCROW DEPOSITS"),
together with any interest earned thereon, shall be held by Escrow Agent, in
trust, and disposed of only in accordance with the following provisions.

          (a) Escrow Agent shall invest the Deposit, if made in cash, in an
interest-bearing account at Citibank, N.A. and shall not commingle the Escrow
Deposits with any funds of Escrow Agent or others.

          (b) If the Closing occurs, Escrow Agent shall deliver the Escrow
Deposits if held as cash to, or upon the instructions of, Seller on the Closing
Date. If the Deposit is held as a letter of credit then upon the Closing, Escrow
Agent shall return such letter of credit to Buyer.

          (c) If for any reason the Closing does not occur, Escrow Agent shall
deliver the Escrow Deposits (and all interest earned thereon if made in cash) to
Seller or Buyer only upon receipt of a written demand therefor from such party,
subject to the following provisions of this Subsection 12.1(c) or of Section
12.4, as applicable. If for any reason the Closing does not occur and Escrow
Agent receives a written demand for payment of Escrow Deposits (and all interest
earned thereon if made in cash) or a written demand for delivery of the Letter
of Credit (if the Deposit was made with a letter of credit), Escrow Agent shall
give written notice to the other party of such demand. If Escrow Agent does not
receive a written objection from the other party to either the proposed payment
or the proposed delivery of the Letter of Credit within ten (10) days after the
giving of such notice, Escrow Agent is hereby authorized to make such payment or
deliver the Letter of Credit to the party making the demand. If Escrow Agent
does receive such written objection within such period, Escrow Agent shall
continue to hold the Escrow Deposits until otherwise directed by written
instructions signed by Seller and Buyer or a final judgment of a court.

     .2 Indemnity. The parties acknowledge that Escrow Agent is acting solely as
a stakeholder at their request and for their convenience, that Escrow Agent
shall not be deemed to be the agent of either of the parties, and that Escrow
Agent shall not be liable to either of the parties for any action or omission on
its part taken or made in good faith, and not in disregard of this Agreement,
but shall be liable for its negligent acts and for any loss, cost or expense
incurred by Seller or Buyer resulting from Escrow Agent's mistake of law
respecting the Escrow Agent's scope or nature of its duties. Seller and Buyer
shall jointly and severally indemnify and hold Escrow Agent harmless from and
against all costs, claims and expenses, including reasonable attorneys' fees,
incurred in connection with the performance of Escrow Agent's duties hereunder,
except with respect to actions or omissions taken or made by Escrow Agent in bad
faith, in disregard of this Agreement or involving negligence on the part of
Escrow Agent.

     .3 Income Tax. Buyer shall pay any income taxes on any interest earned on
and any other income derived from the Escrow Deposits. Buyer represents and
warrants to Escrow Agent that its taxpayer identification number is pending.

     .4 Letter of Credit. If Buyer chooses to deliver a Letter of Credit instead
of cash as the Deposit pursuant to Section 2.2, such Letter of Credit shall (a)
be delivered to Escrow Agent, (b) be payable to Seller as beneficiary, (c) have
an expiration date not earlier than one year from its date of issuance, (d) be
in a face amount of SEVEN MILLION FIVE HUNDRED THOUSAND DOLLARS AND NO/100
DOLLARS ($7,500,000.00), (e) be drawable by Seller upon presentation to the
issuer of a writing signed by a duly authorized officer of Seller stating either
(i) that the beneficiary is entitled to receipt of the Deposit pursuant to the
terms of this Agreement or (ii) the Letter of Credit will expire within thirty
(30) days of the date on which the drawing is made and no replacement Letter of
Credit has been delivered to Escrow Agent, and (f) shall constitute an
irrevocable obligation by the issuer to make payment to Seller in the full
amount outstanding under such Letter of Credit upon receipt of such a writing.
If Seller draws upon the Letter of Credit in the circumstances described in
Clause (ii), Seller shall be obligated to deliver the proceeds thereof to Escrow
Agent who will hold the same as if the Deposit were made in cash pursuant to the
terms of this Agreement.

     .5 Confirmation of Escrow. Escrow Agent has executed this Agreement in the
place indicated on the signature pages hereof in order to confirm that Escrow
Agent has received and shall (a) hold the Escrow Deposits if the same is made in
cash, and the interest earned thereon and any other income derived therefrom, in
escrow, and shall disburse the Escrow Deposits and the interest earned thereon
and any other income derived therefrom, pursuant to the provisions of this
Article 12, or (b) has received the Letter of Credit and shall hold such Letter
of Credit until the Closing or demand is made upon Escrow Agent for such Letter
of Credit pursuant to this Article 12.

                                   ARTICLE 13
                                 LEASE EXPENSES

     .1 Certain Definitions. For purposes of this Agreement, the following terms
shall have the following meanings:

          "NEW LEASES" shall mean, collectively, any lease for space at the Real
Property entered into between the Contract Date and the Closing Date.

          "PRE-CONTRACT LEASES" shall mean, collectively, any lease for space at
the Real Property in effect as of the Contract Date.

          "REIMBURSABLE LEASE EXPENSES" shall mean, collectively, any and all
fees paid by Seller prior to the Closing or costs and expenses incurred by
Seller prior to the Closing arising out of or in connection with any extensions,
renewals or expansions under any Lease exercised or granted between the Contract
Date and the Closing Date, and any New Lease entered into in accordance with
this Agreement. The Reimbursable Lease Expenses shall include (a) brokerage
commissions and fees to effect any such leasing transaction, (b) expenses
incurred for repairs, improvements, equipment, painting, decorating,
partitioning and other items to satisfy the tenant's requirements with regard to
such leasing transaction, (c) legal fees for services rendered in connection
with the preparation of documents and other services rendered in connection with
the effectuation of the leasing transaction, (d) if there are any rent
concessions covering any period that the tenant has the right to be in
possession of the demised space, the rents that would have accrued during the
period of such concession prior to the Closing Date as if such concession were
amortized over (i) with respect to any extension or renewal, the term of such
extension or renewal, (ii) with respect to any expansion, that portion of the
term remaining under the subject Lease after the date of any expansion, or (iii)
with respect to any New Lease, the entire initial term of any such New Lease,
and (e) expenses incurred for the purpose of satisfying or terminating the
obligations of a tenant under a New Lease to the landlord under another lease
(whether or not such other lease covers space in the Real Property).

     .2 Future Agreements and Modifications. From and after the date hereof and
until the first to occur of (i) the termination of this Agreement or (ii) the
Closing Date, Seller will not enter into any New Leases or amendments to
Pre-Contract Leases affecting all or a portion of the Property without the prior
written consent of Buyer, which consent will not be unreasonably withheld,
conditioned or delayed. Seller shall furnish Buyer with a written notice of the
proposed action which shall contain information regarding the proposed action
Seller believes is reasonably necessary to enable Buyer to make informed
decisions with respect to the advisability of the proposed action. Any notice
from Buyer rejecting the proposed action shall include a description of the
reasons for Buyer's rejection. The foregoing consent requirement will not apply
to any New Leases or unexecuted amendments to Pre-Contract Leases submitted to
prospective or existing tenants for signature prior to the date hereof, provided
that copies of any such new Leases or amendments to Pre-Contract Leases have
been delivered to Buyer prior to the later of (y) the date hereof or (z) the
date of any such amendment, modification, renewal, extension or expansion
provided for or required by the terms of any Pre-Contract Lease.

     .3 Lease and Contract Expenses. The Company will be responsible for all
obligations payable on or after the Closing Date pursuant to Pre-Contract
Leases, New Leases entered into in accordance with this Agreement, and Contracts
in effect as of the Closing Date, subject to the limitations set forth in
Subsection 9.2.1. Such obligations, with respect to Pre-Contract Leases and New
Leases, shall include all tenant costs and capital costs thereunder for which
landlord is responsible, including free rent, tenant improvement allowances,
tenant work and the like, provided that Seller was not obligated to complete
fully or otherwise fully perform the foregoing prior to the Closing Date.
Notwithstanding the foregoing, except as set forth in Subsection 9.2.6 and
except for any leasing commissions resulting from any lease extension entered
into with the law firm of Kreindler & Kreindler (the cost of which shall be
borne by the Company), Seller will be responsible for any such obligation if,
and to the extent, as of the Contract Date, such obligation was enforceable
against, or payable by, Seller as a result of a state of facts existing on the
Contract Date (without regard to when the obligation is payable or to be
otherwise performed). By way of example, but without limitation of the
generality of the foregoing, Seller will be responsible for all leasing
commissions that are payable in installments with respect to an effective
Pre-Contract Lease in its current lease term, but will not be responsible for
any leasing commissions that become payable only upon the exercise of an
extension option on a Pre-Contract Lease, which option has not been exercised on
or prior to the Contract Date.

     .4 Lease Enforcement. Prior to the Closing Date, Seller shall have the
right, but not the obligation (except to the extent that Seller's failure to act
shall constitute a waiver of such rights or remedies), to enforce the rights and
remedies of the landlord under any Pre-Contract Lease or New Lease, by summary
proceedings or otherwise (including the right to remove any tenant), and to
apply all or any portion of any security deposits then held by Seller toward any
loss or damage incurred by Seller by reason of any defaults by tenants, and the
exercise of any such rights or remedies shall not affect the obligations of
Buyer under this Agreement in any manner or entitle Buyer to a reduction in, or
credit or allowance against, the Purchase Price or give rise to any other claim
on the part of Buyer.

                                   ARTICLE 14
                                  MISCELLANEOUS

     .1 Assignment. Neither Buyer nor Seller shall assign this Agreement or
their respective rights hereunder to any individual or entity without the prior
written consent of the other party, which consent such party may grant or
withhold in its sole discretion, and any such assignment shall be null and void
AB INITIO. Notwithstanding the foregoing, Seller may assign its rights under
this Agreement to a wholly owned subsidiary of Seller.

     .2 Designation Agreement. Section 6045(e) of the Internal Revenue Code and
the regulations promulgated thereunder (herein collectively called the
"REPORTING REQUIREMENTS") require an information return to be made to the United
States Internal Revenue Service, and a statement to be furnished to Seller, in
connection with the Transactions. Escrow Agent is either the person responsible
for closing the Transactions (as described in the Reporting Requirements) or the
disbursing title or escrow company that is most significant in terms of gross
proceeds disbursed in connection with the Transactions (as described in the
Reporting Requirements) (Escrow Agent in such capacity, "AGENT"). Accordingly:

          (a) Agent is hereby designated as the "REPORTING PERSON" (as defined
in the Reporting Requirements) for the Transactions. Agent shall perform all
duties that are required by the Reporting Requirements to be performed by the
Reporting Person for the Transactions.

          (b) Seller and Buyer shall furnish, and shall cause the Company to
furnish, to Agent, in a timely manner, any information requested by Agent and
necessary for Agent to perform its duties as Reporting Person for the
Transactions.

          (c) Agent hereby requests Seller to furnish to Agent Seller's correct
taxpayer identification number. Seller acknowledges that any failure by Seller
to provide Agent with Seller's correct taxpayer identification number may
subject Seller to civil or criminal penalties imposed by law. Accordingly,
Seller hereby certifies to Agent, under penalties of perjury, that Seller's
correct taxpayer identification number is 22-1211670.

          (d) Each of the parties hereto shall retain this Agreement for a
period of four (4) years following the calendar year during which the Closing
occurs.

     .3 Survival/Merger. Except for the provisions of this Agreement that are
explicitly stated to survive the Closing, (a) none of the terms of this
Agreement shall survive the Closing, and (b) the delivery of the Deed and any
other documents and instruments by Seller and the acceptance thereof by the
Company or Buyer (as the case may be) shall effect a merger, and be deemed the
full performance and discharge of every obligation on the part of Buyer, the
Company and Seller to be performed hereunder.

     .4 Integration; Waiver. This Agreement, together with the Exhibits hereto
and the Joinder annexed hereto, embodies and constitutes the entire
understanding between the parties with respect to the Transactions and all prior
agreements, understandings, representations and statements, oral or written, are
merged into this Agreement. Neither this Agreement nor any provision hereof may
be waived, modified, amended, discharged or terminated except by an instrument
signed by the party against whom the enforcement of such waiver, modification,
amendment, discharge or termination is sought, and then only to the extent set
forth in such instrument. No waiver by either party hereto of any failure or

     .10 Counterparts. This Agreement may be executed in counterparts, each of
which shall be an original and all of which counterparts taken together shall
constitute one and the same agreement.

     .11 No Recordation. Seller and Buyer each agrees that neither this
Agreement nor any memorandum or notice hereof shall be recorded and Buyer agrees
(a) not to file any notice of pendency or other instrument (other than a
judgment) against the Property or any portion thereof in connection herewith and
(b) to indemnify Seller against all costs, expenses and damages, including
reasonable attorneys' fees and disbursements, incurred by Seller by reason of
the filing by Buyer of such notice of pendency or other instrument.

     .12 Additional Agreements; Further Assurances. Subject to the terms and
conditions herein provided, each of the parties hereto shall execute and deliver
such documents as the other party shall reasonably request in order to
consummate and make effective the Transactions; provided, however, that the
execution and delivery of such documents by such party shall not result in any
additional liability or cost to such party.

     .13 Construction. (a) The parties acknowledge that each party and its
counsel have reviewed and revised this Agreement and that the normal rule of
construction to the effect that any ambiguities are to be resolved against the
drafting party shall not be employed in the interpretation of this Agreement or
any amendment hereof or Exhibit hereto.

          (b) The definitions used in this Agreement shall apply equally to both
the singular and plural forms of the terms defined. Whenever the context may
require, any pronoun shall include the corresponding masculine, feminine and
neuter form. The words "include," "includes" and "including" shall be deemed to
be followed by the phrase "without limitation," except where the context
otherwise requires. The terms "herein," "hereof" and "hereunder" refer to this
Agreement in its entirety unless the context otherwise requires. References to
contracts, agreements, leases and other contractual instruments shall be deemed
to include all subsequent amendments, supplements and other modifications
permitted by the terms of this Agreement. References to specific statutes
include (i) successor statutes of similar purpose and import, and (ii) all
rules, regulations and orders promulgated thereunder. The term "provisions,"
when used with respect hereto or to any other document or instrument shall be
construed as if preceded by the phrase "terms, covenants, agreements,
requirements, conditions and/or."

     .14 ERISA. (a) To satisfy compliance with ERISA, Buyer represents and
warrants to Seller that:

          (i) Neither Buyer nor any of its affiliates (within the meaning of
Part V(c) of Prohibited Transaction Exemption 84-14 granted by the U.S.
Department of Labor ("PTE 84-14")) has, or during the immediately preceding
calendar year has exercised, the authority to appoint or terminate Seller as
investment manager of any assets of the employee benefit plans whose assets are
held by Seller or to negotiate the terms of any management agreement with Seller
on behalf of any such plan;

          (ii) The Transactions are not specifically excluded by Part I(b) of
PTE 84-14; and

          (iii) Buyer is not a related party of Seller (as defined in Part V(h)
of PTE 84-14).

          (b) Buyer hereby agrees to execute or deliver such documents or
provide such information as Seller may require in connection with the
Transactions or to otherwise assure Seller that: (i) the Transactions are not a
prohibited transaction under ERISA, (ii) that the Transactions are otherwise in
full compliance with ERISA and (iii) that Seller is not in violation of ERISA by
compliance with this Agreement and by closing the Transactions. Seller shall not
be obligated to consummate the Transactions unless and until the Transactions
comply with ERISA and Seller is satisfied that the Transactions comply in all
respects with ERISA. The obligations of Buyer under this Section shall survive
the Closing and shall not be merged therein.

     .15 Business Day. As used herein, the term "BUSINESS DAY" shall mean any
day other than a Saturday, Sunday, or any federal or state holiday. If any
period expires on a day that is not a Business Day or any event or condition is
required by the terms of this Agreement to occur or be fulfilled on a day which
is not a Business Day, such period shall expire or such event or condition shall
occur or be fulfilled, as the case may be, on the next succeeding Business Day.

     .16 Seller's Maximum Aggregate Liability. Notwithstanding any provision to
the contrary contained in this Agreement or any documents executed or delivered
by Seller pursuant hereto or in connection herewith, the maximum aggregate
liability of Seller, and the maximum aggregate amount that may be awarded to and
collected by Buyer or the Company, in connection with the Transactions and under
this Agreement (including in connection with the breach of any representations
and warranties contained herein) and any and all agreements, documents or
instruments executed or delivered pursuant hereto or in connection herewith, for
which a claim is timely made by Buyer shall not exceed FOUR MILLION AND 00/100
DOLLARS ($4,000,000.00); provided that such limitation on liability shall not
apply with respect to (a) Seller's obligations as a member of the Company
pursuant to the Operating Agreement, (b) liability resulting from non-recourse
carve-out provisions that may be agreed to by the Company in the documents
relating to the Mortgage Loan, (c) Seller's obligations with respect to transfer
taxes as described in Subsection 5.4(c), or (d) the Limited Guaranty Agreement
described in Subsection 9.2.7.

     .17 JURISDICTION. WITH RESPECT TO ANY SUIT, ACTION OR PROCEEDINGS RELATING
TO THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREBY, THE PROPERTY OR THE
RELATIONSHIP OF BUYER AND SELLER HEREUNDER (HEREIN COLLECTIVELY CALLED THE
"PROCEEDINGS"), EACH PARTY HERETO IRREVOCABLY (A) SUBMITS TO THE EXCLUSIVE
JURISDICTION OF THE COURTS OF THE COUNTY OF NEW YORK, STATE OF NEW YORK AND THE
UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK, AND (B)
WAIVES ANY OBJECTION WHICH IT MAY HAVE AT ANY TIME TO THE LAYING OF VENUE OF ANY
PROCEEDINGS BROUGHT IN ANY SUCH COURT, WAIVES ANY CLAIM THAT SUCH PROCEEDINGS
HAVE BEEN BROUGHT IN AN INCONVENIENT FORUM AND FURTHER WAIVES THE RIGHT TO
OBJECT, WITH RESPECT TO SUCH PROCEEDINGS, THAT SUCH COURT DOES NOT HAVE
JURISDICTION OVER SUCH PARTY.

     .18 WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES TRIAL BY JURY IN
ANY PROCEEDINGS BROUGHT BY THE OTHER PARTY IN CONNECTION WITH ANY MATTER ARISING
OUT OF OR IN ANY WAY CONNECTED WITH THIS AGREEMENT, THE TRANSACTIONS
CONTEMPLATED HEREBY, THE PROPERTY OR THE RELATIONSHIP OF BUYER AND SELLER
HEREUNDER.

                             construed to affect or impair any rights or
                             remedies that Buyer may have against Seller as a

                (vi) Buyer and the Company acknowledge and agree that the
                     provisions of this Subsection (c) were a material factor in
                     Seller's acceptance of the Purchase Price, the transfer of
                     the Property to the Company and, while Seller has provided

                     Seller is unwilling to transfer the Property to the Company
                     or to transfer or to cause the transfer of the Interests in
                     the Company to Buyer unless Seller and the other Seller
                     Parties are expressly released as set forth in Subsection
                     (c) and Buyer and the Company each assumes the obligations
                     specified in, and provides the indemnifications set forth
                     in, Subsection (c).

         (d)      Notwithstanding anything to the contrary herein, the
provisions of this Agreement shall survive the Closing and shall not be merged
therein.

         (e)      For purposes of the Sale Agreement, Buyer, individually and on
behalf of the Company, and the Company shall each be "deemed to know" of the
existence of a fact or circumstance to the extent that such fact or circumstance
is disclosed by this Agreement or in the Sale Agreement, the Documents, any
estoppel certificate executed by any tenant of the Property and delivered to
Buyer, Buyer's Representatives or the Company, or any studies, tests, reports,

Representatives, or otherwise obtained by Buyer, the Company or Buyer's

Section 1445 of the Internal Revenue Code provides that a transferee of a United
States real property interest must withhold tax if the transferor is a foreign

INSURANCE COMPANY OF AMERICA, a New Jersey corporation ("PRUDENTIAL"), the
undersigned hereby certifies the following on behalf of Prudential:

         Prudential is not a foreign corporation, foreign partnership, foreign
trust, or foreign estate (as those terms are defined in the Internal Revenue
Code and Income Tax Regulations); and

         Prudential's U.S. employer tax identification number is 22-1211670; and

         Prudential's office address is 751 Broad Street, Newark, New Jersey,
07102-3777.


Prudential understands that this certification may be disclosed to the Internal
Revenue Service by transferee and that any false statement contained herein
could be punished by fine, imprisonment, or both.


The undersigned officer of Prudential declares that he has examined this
certification and to the best of his knowledge and belief it is true, correct
and complete, and he further declares that he has authority to sign this
document on behalf of Prudential.

The undersigned ("SELLER") hereby certifies as of the date hereof, the
following:

     1. Attached hereto is a true, correct and complete copy of the
above-described Lease along with all amendments and modifications thereto
(herein collectively called the "LEASE").

     2. The Lease is in full force and effect and has not been amended,

     3. The information describing the Lease as shown above is correct except as
follows:



This letter is given by Seller to (the "COMPANY") in connection with a Purchase
and Sale Agreement (the "SALE AGREEMENT") between Seller, as seller, and SL
Green 100 Park LLC, as buyer ("BUYER"), dated as of November 19, 1999, which
provides for, among other things, the sale of a 49.9% ownership interest (the
"INTERESTS") in the Company to Buyer, which Company shall, immediately prior to
the transactions contemplated in the Sale Agreement, own and control the 100%
fee interest in certain real property, personal property and related property
rights located in County of New York, State of New York, and is intended solely
for the benefit of the Company and no other person or entity may rely on any
matter set forth herein. All capitalized terms used herein without definition
shall have the respective meanings ascribed to such terms in the Sale Agreement.


Seller shall only be liable to the Company or Buyer hereunder for a breach of a
representation and warranty made herein with respect to which a claim is made by
the Company against Seller on or before the one hundred eightieth (180th) day
after the date hereof; provided, however, that if Seller obtains a Clean
Estoppel from the tenant identified hereinabove after the date hereof that
complies with the terms of Subsection 6.3(m) of the Sale Agreement, this letter
shall be without further force or effect as of the date of such tenant's
estoppel certificate.


Anything in this letter to the contrary notwithstanding, the maximum aggregate
liability of Seller for Seller's misrepresentations or breaches of warranties
herein or in any documents executed or delivered by Seller at or prior to the
Closing (including, but not limited to, any of Seller's representation letters
delivered in lieu of tenant estoppels) shall be limited as set forth in Section
14.16 of the Sale Agreement. Notwithstanding the foregoing, however, if the
Closing occurs, Buyer hereby expressly waives, relinquishes and releases any
right or remedy available to it at law, in equity or under the Sale Agreement to
make a claim against Seller for damages that Buyer may incur, or to rescind the
Sale Agreement and the Transactions, as the result of any of Seller's
representations or warranties being untrue, inaccurate or incorrect if (a) Buyer
knew or is deemed to know that such representation or warranty was untrue,
inaccurate or incorrect at the time of the Closing, or (b) Buyer's damages as a
result of all such representations or warranties being untrue, inaccurate or
incorrect, when taken together, are reasonably estimated to aggregate less than
TWO HUNDRED FIFTY THOUSAND AND NO/100 DOLLARS ($250,000.00).

Delaware limited liability company (the "COMPANY").

                              W I T N E S S E T H:


         WHEREAS, Guarantor, as seller, and SL Green 100 Park LLC, as buyer
("BUYER"), are parties to a Purchase and Sale Agreement (the "SALE AGREEMENT")
dated as of November 19, 1999, which provides for, among other things, the sale
of a 49.9% ownership interest (the "INTERESTS") in the Company, which Company
shall, immediately prior to and after giving effect to the transactions
contemplated in the Sale Agreement, own and control the 100% fee interest in
certain real property, personal property and related property rights (the
"PROPERTY") located in County of New York, State of New York, commonly referred
to as 100 Park Avenue. Any initially capitalized terms not otherwise defined
herein shall have the meaning ascribed to such term in the operating agreement
of the Company ("OPERATING AGREEMENT");

         WHEREAS, Buyer is willing to purchase the Interests only if Guarantor
agrees to guaranty payment of the Guaranteed Obligations (defined below) to the
Company in the manner hereinafter provided;

          WHEREAS, Guarantor is willing to agree to guaranty payment of the
Guaranteed Obligations to the Company upon and subject to the terms and
conditions herein, including the Company's Reimbursement Obligations (defined
below),

         NOW, THEREFORE, in consideration of the foregoing recitals, which are
incorporated into the operative provisions of this Agreement by this reference,
and for good and valuable other consideration, the receipt and adequacy of which
are hereby conclusively acknowledged, and intending to be legally bound hereby,
Guarantor and the Company hereby agree as follows:

         1. GUARANTY OF PAYMENT. Guarantor hereby unconditionally and
irrevocably, guarantees, as primary obligor and not merely as surety, to the
Company and its successors, endorsees and/or assigns:

            (a) The payment of an amount (the "BASE GUARANTY AMOUNT") equal to
(i) One Million Dollars ($1,000,000.00) less (ii) the gross fixed or base rental
income received by the Company in respect of Suites 2100, 2400 and 3601 of the
Property (the "GUARANTY SPACE") without reference to so-called "pass-throughs"
or "reimbursables" (the "RENTAL INCOME") during the one year period commencing
on the date hereof (the "INITIAL Year").

            (b) The payment upon demand of all reasonable out-of-pocket costs
and expenses actually incurred by the Company in the collection of, enforcement
of, or realization under, this Agreement. The payment obligations guaranteed
pursuant to this Section 1 are hereinafter referred to as the "GUARANTEED
OBLIGATIONS".

         2. DETERMINATION AND PAYMENT OF BASE GUARANTY AMOUNT. (a) The Base
Guaranty Amount shall be determined by the Company's Accountants based upon a
review of the relevant portions of the Company's books, bank account statements
and written statements from the tenants, if any, that are leasing or occupying
any portion of the Guaranty Space and such other information as the Company
and/or Guarantor deems to be reasonably relevant to the analysis. The Company
shall provide all relevant information to the Accountants as soon as practically
possible after the end of the Initial Year, but not later than ninety (90) days
thereafter. The Company's Accountants shall determine the Base Guaranty Amount
as promptly as possible after receipt of such information and shall notify all
parties promptly of its conclusive determination in writing. The failure of
Company's Accountant to give such notice shall not affect Guarantor's
obligations or constitute a defense thereto; provided that no Guaranteed
Obligations shall be paid until the Accountants have made their conclusive
determination. The Accountants' conclusions shall be binding absent manifest
error.

            (b) Guarantor shall pay the Base Guarantee Amount to the Company
within sixty (60) days after the Accountants' notice is delivered to Guarantor.

         3. REPRESENTATIONS AND WARRANTIES. Guarantor represents and warrants
that:

            (a) No consents or approvals of any kind by any other Person (other
than those heretofore obtained), and no license, permit, approval or
authorization of, exemption by, notice or report to, or registration, filing or
declaration with, any governmental authority is required of Guarantor in
connection with this Agreement or the execution, delivery or performance of this
Agreement and Guarantor's obligations hereunder;

            (b) There is no pending or, to Guarantor's knowledge, threatened
action or proceeding affecting Guarantor before any court, governmental agency
or arbitrator that could reasonably be expected to have a material adverse
effect on the ability of Guarantor to perform or observe any of its obligations
hereunder or that could reasonably be expected to have a material adverse effect
on Guarantor's guaranty of the Guaranteed Obligations hereunder;

            (c) Guarantor has full power, authority and legal right to execute
and deliver this Agreement and to observe and perform all of the terms of this
Agreement to be observed and performed;

            (d) The execution, delivery and performance by the Guarantor of this
Agreement have been duly authorized by all necessary corporate action on its
part, and this Agreement has been duly and validly executed and delivered by the
Guarantor and constitutes its legal, valid and binding obligation, enforceable
in accordance with its terms, subject to rights of creditors generally and
principles of equity; and

            (e) None of the execution and delivery of this Agreement, the
consummation of the transactions herein contemplated or compliance with the
terms and provisions hereof will conflict with or result in a breach of, or
require any consent under, the charter or by-laws of Guarantor, or any
applicable law or regulation, or any order, writ, injunction or decree of any
court or governmental authority or agency, or any agreement or instrument to
which the Guarantor or any of its subsidiaries or affiliates is a party or by
which any of them is bound or to which any of them is subject, or constitute a
default under any such agreement or instrument.

         4. RELEASE OF GUARANTY. If the Company receives gross fixed or base
rent payments of One Million Dollars ($1,000,000.00) or more during the Initial
Year with respect to the Guaranty Space (other than funds determined by the
Company's Accountants to be payments made by or on behalf of tenants for
so-called "pass-throughs" or "reimbursables"), this Agreement shall
automatically terminate and become of no further force or effect.

         5. LIABILITY OF GUARANTOR. (a) Guarantor agrees that its obligations
hereunder are irrevocable, absolute, independent and unconditional and shall not
be affected by any circumstance that constitutes a legal or equitable discharge
of a guarantor or surety other than indefeasible payment in full of the
Guaranteed Obligations; provided, however, that Guarantor's payment obligations
shall be limited to the assets of the PRISA account. In furtherance of, and
without limiting the generality of, the foregoing, Guarantor agrees as follows:

            (i) This Agreement is a guaranty of payment and not of collection or
collectibility.

            (ii) Payment by Guarantor of a portion, but not all, of the
Guaranteed Obligations shall in no way limit, affect, modify or abridge
Guarantor's liability for any portion of the Guaranteed Obligations that has not
been paid.

            (b) Notwithstanding anything to the contrary contained herein, the
obligations of Guarantor shall not be construed under any circumstances to be an
assumption by Guarantor of any obligation with respect to reimbursable expenses,
tenant improvement allowances, tenant work and the like (it being understood and
agreed that such reimbursable expenses and capital costs shall be the
responsibility of the Company).

         6. WAIVERS BY GUARANTOR. Guarantor hereby waives, for the benefit of
the Company:

            (a) Any defense arising by reason of the incapacity, lack of
authority or any disability or other defense of Guarantor, including any defense
based on or arising out of the lack of validity or the unenforceability of the
Guaranteed Obligations or any agreement or instrument relating thereto;

            (b) Any principles or provisions of law, statutory or otherwise,
that are or might be in conflict with the terms of this Agreement and any legal
or equitable discharge of Guarantor's obligations hereunder;

            (c) The benefit of any statute of limitations affecting Guarantor's
liability hereunder or the enforcement hereof; and

            (d) Notices, demands, presentments, demands for payment, protests,
notices of protest, notices of dishonor and notices of any action or inaction.

         7. GUARANTOR'S RIGHT OF REIMBURSEMENT. Notwithstanding anything to the
contrary contained herein, and as more particularly described in the Operating
Agreement, the Company shall reimburse Guarantor an amount equal to sixty
percent (60%) of the Guaranteed Obligations actually paid by Guarantor to the
Company (a) in equal monthly installments over an 18-month period commencing on
the third (3rd) anniversary hereof or (b) at such earlier time as may be
consistent with the provisions of the Operating Agreement (such obligation, the
"REIMBURSEMENT OBLIGATION").

          8. FURTHER ASSURANCES. At any time or from time to time, upon the
request of the Company, Guarantor shall execute and deliver such further
documents and do such other acts and things as the Company may reasonably
request in order to effect fully the purposes of this Agreement; provided that
the same shall not increase the obligations or decrease the rights, except to a
de minimis extent, of Guarantor hereunder.

         9. NOTICES. Any notice, request, demand, consent, approval and other
communications under this Agreement shall be in writing, and shall be deemed
duly given or made at the time and on the date when received by facsimile
(provided that the sender of such communication shall orally confirm receipt
thereof by the appropriate parties and send a copy of such communication to the

shall be the same as partners in a partnership governed by the relevant
provisions of the Delaware Uniform Partnership Act and the case law
interpreting such act. In no event shall the previous sentence be construed or
applied in such a manner to cause the Company to be treated as a partnership
for any purpose other than the determination of the Members' respective duties
and obligations to one another. The interest of each Member in the Company
shall be personal property for all purposes. To the fullest extent permitted
by applicable law, no Member individually shall have any ownership interest in
any real or other property owned by the Company and all such property
(including the Property) shall be owned by the Company. Notwithstanding
anything in this Section 2.5 to the contrary, the Members intend that the
Company shall at all times be operated in such a manner that it will be taxed
as a partnership for federal and state income tax purposes.

     .6  REIT Provisions.

          (a) The Members recognize that SL Green Realty Corp. ("SLG Realty"),
an indirect owner of SLG, is a real estate investment trust (a "REIT") within
the meaning of Sections 856-859 of the Code. Each Member acknowledges and
agrees that the business of the Company shall be conducted so as to cause the
Company's income and assets to meet the requirements of Sections 856(c)(2),
(c)(3) and (c)(4) and 856(d) of the Code (as if the Company were a REIT) as in
effect from time to time ("REIT Requirements"), provided, however, that
nothing contained in this Subsection 2.6(a) shall permit the Company or the
Regular Managing Member to violate Subsection 6.1(d). The Regular Managing
Member will be responsible for operating the Company in accordance with the
foregoing requirements. In no event shall the Company, without the prior
written approval of SLG, (1) provide services to any tenant of the Property
that the Company is advised in writing by SLG or SLG Realty constitute
noncustomary services for purposes of Section 856(d)(7) of the Code, (2) enter
into any lease or other agreement with any tenant of the Property or service
provider that could adversely affect SLG Realty's status as a REIT, or (3)
acquire any stock in any corporation.

          (b) SLG represents, warrants and covenants to Prudential that no
provision of this Agreement requires that the Company be operated contrary to
REIT Requirements.

     .7  Purposes. The purposes of the Company shall be limited strictly to (a)
acquiring, owning, improving, maintaining, repairing, managing, constructing,
operating and leasing of the Property; (b) financing, refinancing or arranging
financing for any of the foregoing purposes or for making distributions to
Members, including the granting of mortgages or similar liens upon the
Company's property to secure the same; and (c) engaging in such other
operations and businesses as the Company deems necessary or appropriate for
the foregoing purposes subject to the other provisions of this Agreement. The
Company shall not engage in any other business.

     .8  No Individual Authority. Except as otherwise expressly provided in this
Agreement, neither Member, acting alone, shall have any authority to act for,
or to create, undertake or assume any liabilities, obligations or
responsibility on behalf of the other Member or the Company.

     .9  No Restrictions. Nothing contained in this Agreement shall be construed
so as to prohibit either Member or any Affiliate or any director, officer,
partner, employee or other Person related to any of them from owning,
operating, or investing in any real estate or real estate development not
owned or operated by the Company, wherever located and whether or not the same
competes with the Property. Each Member agrees that the other Member, any
Affiliate or any director, officer, employee, partner or other Person related
to such other Member may engage in or possess an interest in another business,
venture or ventures, of any nature and description, independently or with
others, including the ownership, financing, leasing, operation, management,
syndication, brokerage and development of real property other than the
Property, and neither the Company nor the Members shall have any rights by
virtue of this Agreement in and to such independent ventures or to the income
or profits derived therefrom.

     .10  Neither Responsible for Other's Commitments. Neither Member nor the
Company shall be responsible or liable for any indebtedness or obligation of
the other Member incurred either before or after the execution of this
Agreement, except as to those joint responsibilities, liabilities, debts or
obligations incurred pursuant to the terms of this Agreement, and each
indemnifies and agrees to hold the other harmless from such obligations and
debts except as aforesaid.

     .11  Representations by Members.

          (a) Each Member represents and warrants to the other that (1) all
transactions contemplated by this Agreement to be performed by it have been
duly authorized by all necessary action and do not require the consent or
approval of any third party, (2) it has all necessary power with respect
thereto, (3) the consummation of such transactions will not (and with the
giving of notice or lapse of time or both would not) result in a breach or
violation of, or a default or loss of contractual benefits under, its
organizational and/or operational documents, any agreement by which it or any
of its properties is bound, or any statute, regulation, order or other law to
which it or any of its properties is subject, or give rise to a lien or other
encumbrance upon any of its properties or assets, (4) this Agreement is a
valid and legally binding agreement upon such Member, enforceable in
accordance with its terms, subject to applicable "creditors' rights laws and
principles of equity, and (5) such Member is not a "foreign person" as that
term is defined in Section 1445 of the Code.

          (b) SLG further represents, warrants and covenants to Prudential
that SLG is duly organized (or formed), validly existing and in good standing
under the laws of its State of organization and the State in which the
Property is located, has all necessary power to execute and deliver this
Agreement and all documents contemplated hereunder to be executed or delivered
by SLG, and to perform all of its obligations hereunder and thereunder.
Neither the execution and delivery of this Agreement and all documents
contemplated hereunder to be executed or delivered by SLG, nor the performance
of the obligations of SLG hereunder or thereunder, will result in the
violation of any applicable law or any provision of the agreement of
partnership or articles of incorporation and by-laws of SLG or will conflict
with any order or decree of any court or governmental instrumentality of any
nature by which SLG is bound.

          (c) Prudential further represents, warrants and covenants to SLG
that Prudential is duly organized (or formed), validly existing and in good
standing under the laws of its State of organization and the State in which
the Real Property is located and has all necessary power to execute and
deliver this Agreement and all documents contemplated hereunder to be executed
by Prudential and to perform its obligations hereunder and thereunder. Neither
the execution and delivery of this Agreement nor the performance of the
obligations of Prudential hereunder or thereunder, will result in the
violation of any applicable law or any provision of the articles of
incorporation and by-laws of Prudential or will conflict with any order or
decree of any court or governmental instrumentality of any nature by which
Prudential is bound.

                                  ARTICLE 3.
                                     TERM

     .1  Term. The Company shall commence on the date the Certificate of
Formation is filed with the Delaware Secretary of State and shall dissolve
upon the first to occur of the following:

         (a) Transfer or other disposition of all or substantially all of the
Property, other than (1) to a nominee or trustee of the Company for financial
or other business purposes or (2) pledges to secure the Initial Mortgage Loan
or any successor Mortgage Loan; or

         (b) Dissolution of the Company pursuant to the express provisions of
Articles 10, 11, 12 or 13; or

         (c) the fiftieth (50th) anniversary of the date hereof.

     .2  Dissolution. The events of dissolution contained in Section 3.1 are the
only occurrences permitting or requiring dissolution of the Company. Each
Member waives all right, power and authority it may have under the Act or
other legal or equitable rights to require a dissolution of the Company and/or
partition of its assets other than as expressly provided in this Agreement.
The insufficiency of Operating Cash Flow to meet operating and capital costs
on a current basis shall not, to the fullest extent permitted under applicable
law, cause, or give rise to any action or proceeding the result of which might
be the dissolution of Company.

                                  ARTICLE 4.
               CAPITAL ACCOUNTS AND CONTRIBUTIONS OF THE MEMBERS

     .1  Initial Capital Accounts.  Each Member's initial Capital Account
shall be set forth in Exhibit B.

     .2  No Other  Contributions.  Except as  required  by this
Article  4,  neither  Member  shall  have any obligation to make any
contribution to the Company or to advance any funds thereto.

     .3  No Interest  Payable.  No Member shall  receive any interest
on its contributions  to the capital of the Company.

     .4  No Withdrawals. Except as expressly set forth in this Agreement
 (a) the capital of the Company may not be withdrawn, (b) no Member shall
demand or receive a return of any portion of its capital account or any
property of the Company, and (c) no Member shall be permitted to withdraw from
the Company without the consent of all of the Members.

     .5  Additional Capital Contributions.

         (a) If after the date hereof, the Regular Managing Member believes
that Operating Cash Flow (together with any reserves held for such purposes)
is insufficient to timely pay budgeted operating and capital expenses of the
Company pursuant to the approved Annual Operating Budget or the Annual Capital
Budget, as the case may be, the Regular Managing Member shall give each Member
a notice (a "Cash Needs Notice") specifying in reasonable detail (1) the
amount and purpose of any such required capital, (2) subject to Subsection
4.5(c), the date on which such capital is required, and (3) the amount of each
Member's pro rata share of such additional required capital in accordance with
its Percentage Interest (the "Member's Requested Amount"), and (4) the
reasons, to the extent ascertainable, that Operating Cash Flow (together with
any reserves held for such purposes) is insufficient to meet timely the
obligations or purposes for which such additional capital has been requested.

         (b) Each Member shall contribute to the Company, as an additional
capital contribution, an amount equal to the applicable Member's Requested
Amount no later than the date (the "Financial Need Date") specified in the
Cash Needs Notice, which date shall not be earlier than ten (10) days after
the date of receipt of the Cash Needs Notice. A contribution to the Company
made by a Member pursuant to this Subsection 4.5(b) is referred to herein as
an "Additional Capital Contribution." If a Member fails or refuses to make a
capital contribution called for under this Section 4.5, the exclusive remedy
of the Company and the other Member shall be as described in Subsections (d)
and (e) of this Section 4.5.

         (c) Notwithstanding the provisions of Subsection 4.5(b), if the
funds specified in the Cash Needs Notice are requested to pay for the costs
incurred by the Company arising out of an emergency that in the good faith
determination of the Regular Managing Member, threatens the preservation of
all or any material part of any Property or the health or safety of any Person
(an "Emergency), the Financial Need Date shall be seven (7) days after the
date of the Cash Needs Notice; provided that if an Emergency shall exist and a
Member (a "Borrowing Member") shall fail to advance to the Company the
applicable Member's Requested Amount on or before the Financial Need Date,
such amount may be advanced directly to the Company by the other Member on the
Financial Needs Date and treated as a loan by the Member making such advance
to the Borrowing Member (an "Emergency Loan"). Such Emergency Loan shall be
repaid by the Borrowing Member within twenty (20) days after the Financial
Need Date (such twentieth (20th) day following the Financial Need Date, the
"Emergency Loan Repayment Date") together with interest thereon at the rate
described below from the date of such advance to, but not including, the date
of repayment thereof. If made, an Emergency Loan shall bear interest and be
payable upon the terms described in Article 5 and any accrued interest shall
be considered to be part of such Emergency Loan for all purposes. If not
theretofore repaid by the Borrowing Member, the unpaid principal and interest
owing on any Emergency Loan shall be paid out of distributions otherwise
payable to the Borrowing Member under Article 9 and shall not give rise to any
of the remedies set forth in Subsections 4.5(d) and (e).

         (d) If a Member (the "Failing Member") fails to contribute an amount
equal to the entire amount required to be contributed by it by the Financial
Need Date and if the other Member (the "Nonfailing Member") has made its
entire contribution, then, the Nonfailing Member may, but need not:

              (1) withdraw from the Company its most recent proportionate
contribution made pursuant to this Section 4.5, in which case the Company shall
promptly repay the amount of such withdrawn contribution to the Nonfailing
Member;

              (2) make a loan to the Company (a "Special Loan") in an amount
equal to the sum of (x) the contribution that the Failing Member failed to make
pursuant to this Section 4.5, and (y) the contribution made by the Nonfailing
Member, in which case the full contribution made by the Nonfailing Member shall
be deemed instead to be part of the funds advanced in connection with making
such Special Loan. If made, a Special Loan shall bear interest and be payable
upon the terms described in Article 5 and any accrued interest shall be
considered to be part of such Special Loan for all purposes;

              (3) after the expiration of the Interests Transfer Lockout
Period, fund the full amount of the capital due from the Failing Member as an
Additional Capital Contribution to the Company on its own behalf, in which case
Percentage Interests shall be adjusted as set forth in Subsection 4.5(e).

         (e) If the Nonfailing Member elects to fund the full amount of the
capital required as an Additional Capital Contribution in accordance with
Subsection 4.5(d)(3), then effective from the date of the making of such
contribution, the Percentage Interest of the Failing Member shall be reduced
by an amount (expressed as a percentage and rounded to two decimal places)
equal to the ratio of (A) the amount of the capital contribution that the
Failing Member fails to make, over (B) the aggregate amount of all capital
contributions theretofore made by the Failing Member to the Company (less any
capital withdrawals or distributions pursuant to Article 9). For the purpose
of determining the ratio described in the preceding sentence, the Members
shall be deemed to have made capital contributions in the amount of their
respective Initial Capital Account Balances. If the Failing Member's
Percentage Interest is decreased pursuant to the immediately preceding
sentence, the Nonfailing Member's Percentage Interest shall be simultaneously
increased to an amount equal to 100% less the Failing Member's new Percentage
Interest, as calculated pursuant to the immediately preceding sentence. From
and after each time there is a change in the Percentage Interests of the
Members pursuant to this Subsection 4.5(e), the definition of Percentage
Interests under this Agreement shall automatically be changed, and each
Percentage Interest allocation that is referred to in this Agreement shall be
correspondingly changed on a percentage point for percentage point basis even
if the term "Percentage Interests" is not used in the provision in which such
allocation is referenced, including Section 9.2.

     .6  Effect of Change of Percentage Interest. If the Percentage Interests of
the Members are changed pursuant to the terms of this Agreement during any
Fiscal Year, the amounts of all items to be credited, charged or distributed
(including pursuant to Sections 9.2 and 13.5) to such Members for such entire
Fiscal Year in accordance with their respective Percentage Interests in the
Company, shall be allocated between (a) the portion of such Fiscal Year that
precedes the date of such change (and if there shall have been a prior change
in such Fiscal Year, which commences on the date of such prior change) and (b)
the portion of such Fiscal Year that occurs on and after the date of such
change (and if there shall be a subsequent change in such Fiscal Year, that
precedes the date of such subsequent change), in proportion to the number of
days in each such portion, and the amounts of the items so allocated to each
such portion shall be credited, charged or distributed to such Members in
proportion to their respective Percentage Interests in the Company during each
such portion of the Fiscal Year in question.

     .7   Financing.  The  Members  hereby  authorize  the  Company to borrow
up to  $120,000,000  from the  Initial Lender (the "Initial Mortgage Loan").

     .8   Adjustments in Interests Generally. The Members each hereby
acknowledge that because of the difficulty in calculating the damage that may
result from (a) failure of a Member to make an Additional Capital Contribution
when required, and (b) failure to repay a Special Loan together with all
interest thereon when due, the agreements set forth in this Article 4
permitting reductions of a Member's Percentage Interest as a result of such
failures, and the basis of calculations for such reductions, have been openly
and freely negotiated, and have been agreed to, as fair and reasonable
liquidated damages by the Members as parties who are (a) sophisticated in
business, real estate and finance, and (b) advised by experienced legal
counsel.

                                  ARTICLE 5.
                                LOANS BY MEMBER

     .1  Loans. Neither Member shall be obligated to lend any money to the
Company and the Committee may not require such a loan to be made. Except for
Special Loans and Emergency Loans made pursuant to Section 4.5 and the Initial
Mortgage Loan described in Section 4.9, the Company shall not borrow any money
(including any money borrowed pursuant to the Mortgage Loan) without the
approval of the Committee pursuant to Article 6. No Emergency Loan or Special
Loan shall be considered a capital contribution of any Member making such a
loan and no such loan shall increase the Capital Account or Percentage
Interest of such Member or entitle it to any increase in its share of the
distributions of the Company. Each Special Loan or Emergency Loan made by
either Member to the Company shall be an obligation of the Company, provided
that (a) neither Member shall be personally obligated to repay the Special
Loan or Emergency Loan or to make any contribution to the capital of the
Company to enable the Company to repay the Special Loan or Emergency Loan and
(b) the Special Loan or Emergency Loan shall be payable or collectible only
out of the assets of the Company. All Special Loans and Emergency Loans made
pursuant to Section 4.5 shall bear interest at the rate of 5% per annum above
the "prime rate" or "reference rate" announced by Citibank N.A. (the "Prime
Rate") from time to time while such Special Loans or Emergency Loans are
outstanding, or the highest rate permitted by applicable law, whichever is
less. If Citibank N.A. ceases to announce the Prime Rate, the Members shall
reasonably determine a substitute method for determining the Prime Rate.

     .2  Payment of Special Loans and Emergency Loans. Operating Cash Flow and
Extraordinary Cash Flow shall be applied to the payment of Emergency Loans and
Special Loans as set forth in Section 9.2. If at any time Special Loans shall
be outstanding, and if the aggregate balances, including accrued interest, of
such outstanding Special Loans made by the respective Members shall not be in
the proportion of the respective Percentage Interests of the Members, then
payment shall be made only upon the Special Loan of the Member whose loan
balance, including accrued interest, is disproportionately high, until the
balances (including interest) payable on the respective Member's Special Loans
by both Members shall be in the ratio of the respective Percentage Interests
of the Members. If at any time Emergency Loans shall be outstanding, and if
the aggregate balances, including accrued interest, of such outstanding
Emergency Loans made by the respective Members shall not be in the ratio of
the respective Percentage Interests of the Members, then payment shall be made
only upon the Emergency Loan of the Member whose loan balance, including
accrued interest, is disproportionately high, until the balance (including
interest) payable on the respective Member's Emergency Loans by both Members
shall be in the ratio of the respective Percentage Interests of the Members.
When the amounts of the Special Loan and/or Emergency Loan balances (including
interest), as the case may be, of the respective Members are in the ratio of
the Percentage Interests of the respective Members, all payments of interest
on and repayments of the principal of such Special Loans or Emergency Loans
shall be pro rata in accordance with the remaining balance (including
interest) of each of the Special Loans or Emergency Loans.

                                  ARTICLE 6.
                           MANAGEMENT OF THE COMPANY

     .1  Regular Managing Member.

         (a) Subject to the other provisions of this Article 6, the
management of the Company shall be vested in SLG as Regular Managing Member,
which shall be responsible for carrying out the day-to-day operations of the
Company. Except for situations in which the approval of the Members or the
Committee is required by this Agreement or by other nonwaivable provisions of
applicable law, the Regular Managing Member shall have full authority, power
and discretion to manage and control the business, affairs and properties of
the Company, to make all decisions regarding those matters and to perform any
and all other acts or activities customary or incident to the management of
the Company's business. No Member other than the Regular Managing Member shall
be an agent of the Company for the purpose of its business or have the
authority to bind the Company by such Member's acts, except to the extent that
authority has been expressly delegated in writing to such Member by the
Regular Managing Member.

         (b) The Regular Managing Member shall be entitled to hold office
until its resignation or removal. Upon the Regular Managing Member's
resignation or removal, a replacement Regular Managing Member shall be
appointed by a vote of the Majority in Interest of the Company. The Regular
Managing Member, and each replacement Regular Managing Member appointed
hereunder, shall at all times be a Member owning a percentage interest in both
the capital and profits of the Company equal to at least thirty-five percent
(35%).

         (c) Prudential shall have the right to remove SLG as Regular
Managing Member for cause (as defined below) by delivering to SLG a written
notification ("Removal Notice") of removal and stating the cause for that
action. Prudential shall act as Regular Managing Member on behalf of the
Company after it has removed SLG as Regular Managing Member. The grounds for
removal "for cause" shall mean one or more of the following:

               (1)  any willful  and/or  material  misconduct  or material
breach by SLG in the  discharge  of its duties and obligations as Regular
Managing Member;

               (2)  any fraud, gross negligence or willful misconduct in the
performance by SLG of its obligations or covenants under this Agreement or
under any provision of applicable law that Prudential determines in its
reasonable discretion is material;

               (3) any material breach by the Company of its obligations to
any lender, including the Initial Lender, resulting from the willful misconduct
or material breach by SLG as described in Subsection 6.1(c)(1) that causes a
material default under the Initial Mortgage Loan documents, the Mortgage Loan
documents or any other loan document;

              (4)  the termination of the Initial Management Agreement
following the occurrence of the events described in Subsections (c) (as it
applies to the Initial Manager), (d) (as it applies to the Initial Manager),
(f) as it applies to the Initial Manager), (g), (h) or (i) of Section 10.1 of
the Initial Management Agreement, or the resignation of the Initial Manager;
and

              (5) if by operation of Subsection 4.5(e), SLG's Percentage
Interest shall be reduced to thirty five percent (35%) or less.

         (d) The Regular Managing Member shall conduct the activities of the
Company so as to qualify the Company as a "real estate operating company"
("REOC") within the meaning of 29 C.F.R. ss. 2510.3-101 (the "Plan Assets
Regulation"). The "annual valuation period" of the Company for purposes of
qualifying as a REOC under the Plan Assets Regulation shall be the ninety (90)
day period commencing on each Anniversary Date (as defined below) unless the
Company pre-specifies an earlier annual valuation period in accordance with
the Plan Assets Regulation. "Anniversary Date" means each anniversary of the
Company's first investment other than a short-term investment pending
long-term commitment.

     .2  Duties and Obligations of the Manager.

         (a) The Regular Managing Member shall take all actions necessary or
appropriate (1) for the continuation of the Company's valid existence as a
limited liability company under the laws of the State of Delaware and of each
other jurisdiction in which such existence is necessary to enable the Company
to conduct the business in which it is engaged, and (2) for the accomplishment
of the Company's purposes.

         (b) The Regular Managing Member shall devote to the Company such
time as may be necessary for the proper performance of all of its duties under
this Agreement, but the Regular Managing Member shall not be required to
devote full time to the performance of such duties and may have other business
interests or engage in other business activities. Neither the Company nor any
Member shall have any right, by virtue of this Agreement, to share or
participate in such other investments or activities of the Regular Managing
Member. The Regular Managing Member shall not incur any liability to the
Company or to any Member as a result solely of engaging in any other business
or venture.

         (c) Notwithstanding any contrary provision of this Agreement, the
Regular Managing Member shall not be obligated to perform any action as
Regular Managing Member of the Company to the extent such action requires
funding from the Company and such funds have not been provided subsequent to
the issuance of a Cash Needs Notice pursuant to Section 4.5.

     .3  Restrictions on Authority of the Manager.

          (a) Notwithstanding anything herein to the contrary, the Regular
Managing Member shall have no authority to make any Major Decision without the
prior written consent of the Committee as provided in Section 6.4. A "Major
Decision" means any decision to do or perform the following:

              (1)  to approve the Annual Capital Budget and the Annual
Operating  Budget or any  modifications  thereto,  as described in Section 6.5;

              (2)  to cause the Company to acquire any additional material
asset or an interest therein (other than furniture, fixtures and equipment
acquired in the ordinary course of business or assets acquired pursuant to the
then current Annual Operating Budget or Annual Capital Budget, as
appropriate);

              (3)  subject to Section 10.5, to cause a material portion of the
Property to be sold or abandoned or to market the Property;

              (4)  to cause the Company to incur debt financing secured by a
lien on the Property or any other material asset of the Company (other than
the Initial Mortgage Loan or equipment leases and other arrangements of a
similar nature expressly provided for in the Annual Operating Budget);

              (5) to borrow funds in the name of the Company or the Members;

              (6) to cause the Company to refinance any loan obtained by the
Company pursuant to the foregoing Subsections  6.3(a)(4) or (5);

              (7) to cause the Company to extend credit, make loans or become
a surety, guarantor or accommodation endorser for any Person (except as
otherwise permitted in connection with any Special Loans or Emergency Loans);

              (8) to approve the Annual Leasing Plan;

              (9) subject to the provisions of Subsection 6.3(b), to terminate
the Initial Management Agreement or any services provided pursuant to the
Initial Management Agreement, to cause the Company to enter into one or more
substitute management agreements with a substitute property manager from time
to time and to exercise any of the Company's rights to terminate any such
substitute management agreement or any services provided pursuant to any
management agreement from time to time;

              (10) to the extent permitted by the Initial Mortgage Loan
documentation, determine whether and to what extent the Property should be
repaired or restored in the event of any loss by fire or other casualty or in
the event of any loss of any portion of the Property by action in condemnation
or eminent domain;

              (11) to exercise any other rights and prerogatives that are
allocated or provided to the Committee under the terms of this Agreement;

              (12) to alter the frequency of distributions of Operating Cash
Flow as provided for in Article 9;

              (13) to take any "Insolvency Action";

              (14) to sell or issue an equity interest in the Company or,
except as permitted by operation of Article 10, to admit one or  more new
members in the Company;

              (15) to enter into any agreement that creates recourse liability
to all Members;

              (16) to make expenditures in excess of amounts set forth in the
approved Annual Operating Budget or the approved Annual Capital Budget, as the
case may be;

              (17) to invest Company funds in any investment other than a
Permitted Investment;

              (18) to amend this Agreement or the Certificate of Formation;

              (19) to authorize any agreement, transaction or action on behalf
of the Company that is unrelated to its purpose; or

              (20) to authorize or effect a merger or consolidation of the
Company with or into one or more other entities.

         (b) Notwithstanding any contrary provision of this Agreement, all
decisions regarding the termination of any contractor, vendor or service
provider (including the Initial Manager or any other property manager or
leasing agent) that is an Affiliate of or otherwise related to any Member
shall be made by the Committee members appointed or designated by the
unaffiliated Member.

     .4  Executive Committee.

         (a) Except as otherwise provided herein, all Major Decisions shall be
made by a Committee (the "Committee"), which, subject to Subsection 6.4(d),
shall at all times consist of four (4) individuals, two (2) of whom shall be
appointed by Prudential, and two (2) by SLG. Each Member may appoint an

elected to eliminate any variation between the adjusted tax basis and the Book
Basis of an asset, then any Depreciation for that asset will be determined in
accordance with Treasury Regulations Section 1.704-3(d)(2).

     .2  Cash Flow Distributions.

         (a) Operating Cash Flow. Except as otherwise provided in this Section

         (b) Extraordinary Cash Flow. Except as otherwise provided in this
Section 9.2, the Company shall distribute Extraordinary Cash Flow during the
term of the Company within thirty (30) days after the Company's receipt

         (c) Initial Mortgage Loan Proceeds. The Company shall distribute the
proceeds of the Initial Mortgage Loan upon the Company's receipt thereof in
the following order of priority:

              (1) First, to pay the consideration due (in an amount equal to
the principal balance of the Existing Mortgage Loan) in respect to the
assignment of the Existing Mortgage Loan (as defined in the Sale Agreement) to
the holder of the Initial Mortgage Loan;

              (2) Next, to pay all Shared Mortgage Loan Expenses (as defined
in the Sale Agreement);

              (3) Next to pay all other Shared Closing Costs (as defined in
the Sale Agreement); and

              (4) Lastly, to the Members in accordance with their Percentage
Interests.

         (d) Allocations of Accounting Items - Generally. Items attributable
to an Accounting Period shall be determined as though the books of the Company
were closed as of the end of such Accounting Period.

     .3  Distributed Property. Notwithstanding anything to the contrary
contained in the foregoing provisions of Article 9, upon the distribution of
property to a Member, for the purposes of computing Profit or Loss, such
property shall be treated as if it had been sold for its fair market value on
the date of such distribution.

     .4  Nonrecourse Deductions;  Nonrecourse Liabilities;  Minimum Gain
Chargeback; Qualified Income Offset; Corrective Allocations.

         (a) Nonrecourse Deductions. Nonrecourse deductions shall be allocated
among the Members in accordance with their Percentage Interests.

         (b) Nonrecourse Liabilities. For purposes of determining the Member's
respective shares of nonrecourse liabilities of the Company under Treasury
Regulations Section 1.752-3, each Member's "percentage interest in partnership
profits" shall be equal to such Member's Percentage Interest.

         (c) Minimum Gain Chargeback. The allocation contained in this
Subsection 9.4(c) is intended to be a "minimum gain chargeback" as defined in
Treasury Regulations Section 1.704-2(f) on the date hereof and shall be
interpreted in a manner consistent with such regulations. Notwithstanding the
provisions of Section 9.5, if there is a net decrease in the Company's Minimum
Gain for a taxable year then, except to the extent permitted by Treasury
Regulations Section 1.704-2(f)(2), (3), (4) or (5), each Member shall be
allocated items of income and gain for such year (and, if necessary, for
subsequent years) in proportion to, and to the extent of the portion of such
Member's share of the net decrease in the Company's Minimum Gain during such
year.

         (d) Qualified Income Offset. The allocation contained in this
Subsection 9.4(d) is intended to be a "qualified income offset" as defined in
Treasury Regulations Section 1.704-1(b)(2)(ii)(d) on the date hereof and shall
be interpreted in a manner consistent with such regulation. Notwithstanding
the provisions of Section 9.5, a Member shall not be allocated Losses or items
of deduction if such allocation would cause or increase a deficit balance in
such Member's Adjusted Capital Account (as defined below) as of the end of the
calendar year to which such allocation relates. Any such Losses or items of
deductions that would have been allocated to such Member but for the preceding
sentence shall, to the extent permitted by this Subsection 9.4(d), be
allocated to the other Member. In addition, if in any taxable year, a Member
unexpectedly receives an adjustment, allocation or distribution described in
Treasury Regulations Section 1.704-1(b)(2)(ii)(d)(4), (5) or (6), then such
Member shall be allocated gross income equal to the "Qualified Income Offset
Amount." The Qualified Income Offset Amount is the amount by which a Member's
Adjusted Capital Account is exceeded by zero. If in any taxable year to which
this Subsection 9.4(d) applies the amount of items of gross income of the
Company is less than the Qualified Income Offset Amounts for all of the
Members to which this Subsection 9.4(d) applies, then each Member to which
this Subsection 9.4(d) applies shall be allocated a pro rata amount of gross
income, and in subsequent taxable years each of such Members shall be
allocated gross income equal to the amount which, when added to the
allocations to such Member pursuant to this Subsection 9.4(d) in prior taxable
years, will equal the Qualified Income Offset Amount applicable to such Member
for such prior taxable year and for such subsequent taxable years. A Member's
"Adjusted Capital Account" shall mean such Member's Capital Account (1)
reduced for items described in Treasury Regulations Section
1.704-1(b)(2)(ii)(d)(4), (5) or (6) and (2) increased for (i) the amount of
such Member's share of Minimum Gain, (ii) the amount of such Member's Partner
Nonrecourse Debt Minimum Gain and (iii) amounts such Member is obligated to
restore to the Company (if any). For purposes of determining the amount of
expected distributions and expected Capital Account increases, the Book Basis
will be presumed to be the fair market value of Company property.

         (e) Partner Nonrecourse Debt Minimum Gain Chargeback. The allocations
contained in this Subsection 9.4(e) are intended to be a chargeback of Partner
Nonrecourse Debt Minimum Gain as provided in Treasury Regulations Section
1.704-2(i)(4) and shall be interpreted in a manner consistent with such
regulations. If there is a net decrease in the Company's Partner Nonrecourse
Debt Minimum Gain then, except as provided in Treasury Regulations Section
1.704-2(i)(4), each Member with a share of such Partner Nonrecourse Debt
Minimum Gain shall be allocated items of income and gain to the extent of such
Member's share of such net decrease (calculated pursuant to the Treasury
Regulations).

         (f) Partner Nonrecourse Deductions. Partner nonrecourse deductions
(within the meaning of Treasury Regulations Sections 1.704-2(i)(1) and (2))
shall be allocated as prescribed in Treasury Regulations Section
1.704-2(i)(1).

         (g) Corrective Allocations. Any special allocations pursuant to
Subsection 9.4(c), (d) or (e) shall be taken into account for the purpose of
equitably adjusting subsequent allocations so that the net allocations, in the
aggregate, allocated to each Member pursuant to this Article 9, and the
Capital Accounts of each Member, shall as expeditiously as possible and to the
extent possible without violating the constraints set forth in Subsection
9.4(c), (d) or (e), be the same as if no special allocations had been made
under Subsection 9.4(c), (d) or (e).

     .5  Allocations  of Profits and Losses.  After  giving  effect to the
special  allocations  set forth in this Agreement,

         (a) Profits shall be allocated:

              (1) first to the Members in proportion to and to the extent of
the excess, if any, of (i) the cumulative Losses allocated to them pursuant to
the proviso at the end of Subsection 9.5(c), for all prior Accounting Periods,
over (ii) the cumulative Profits allocated pursuant to this Subsection
9.5(a)(1) for all prior Accounting Periods; and

              (2) then to the Members in proportion to and to the extent of
the excess, if any, of (i) the cumulative Losses allocated to them pursuant to
Subsection 9.5(b)(3), for all prior Accounting Periods, over (ii) the
cumulative Profits allocated pursuant to this Subsection 9.5(a)(2) for all
prior Accounting Periods; and

              (3) thereafter to the Members in proportion to their Percentage
Interests.

         (b) Losses shall be allocated:

              (1) first to the Members, in proportion to and to the extent of
the excess, if any, of (i) the cumulative Profits allocated to each Member
pursuant to Subsection 9.5(a)(2) for all prior Accounting Periods, over (ii)
the cumulative Losses allocated to such members pursuant to this Subsection
9.5(b)(1);

              (2) second to the Members in proportion to and to the extent of
the excess, if any, of (i) the cumulative Profits allocated to each Member
pursuant to Subsection 9.5(a)(1) for all prior Accounting Periods, over (ii)
the cumulative Losses allocated to such Members pursuant to this Subsection
9.5(b)(2); and

              (3) the balance, if any, to the Members in proportion to their
Percentage Interests.

         (c) The Losses allocated pursuant to Subsection 9.5(b) shall not
exceed the maximum amount of Losses that can be allocated without causing any
Member to have a deficit in its Capital Account at the end of any Accounting
Period. If some but not all of the Members would have a deficit in their
Capital Accounts at the end of an Accounting Period as a result of the
allocation of Losses pursuant to Subsection 9.5(b), the limitation set forth
in this Subsection 9.5(c) shall be applied by allocating Losses hereunder only
to the extent that such allocation would not cause a Member to have such a
deficit in its Capital Account as a consequence of receiving such allocation
of Losses (such allocation of Losses to be in proportion to Percentage
Interests); provided, however, that if no Member may receive an additional
allocation of Losses pursuant to this Section 9.5(c), such additional Losses
shall be allocated solely to those Members who bear the economic risks for
such additional Losses within the meaning of Section 704(b) of the Code and
the regulations thereunder.

     .6  Allocations for Income Tax Purposes. The income, gains, losses,
deductions and credits of the Company for federal, state and local income tax
purposes shall be allocated in the same manner as the corresponding items
entering into the computation of Profits and Losses were allocated pursuant to
Section 9.5; provided that solely for such income tax purposes and not for
Capital Account purposes, income, gains, losses, deductions and credits of the
Company shall be allocated among the Members so as to take into account any
variation between the adjusted tax basis for federal income tax purposes of
any asset and its Book Basis (a) at the time of contribution for any property
contributed to the Company, and (b) at the time the Book Basis is adjusted, in
the event any Company asset is revalued. If, for federal income tax purposes,
SLG is deemed to have purchased 49.9% of the Property upon its purchase of its
interest in the Company, the Company shall use the remedial allocation method
as permitted under Treasury Regulation Section 1.704-3(d) in order to take
into account such variation with respect to the Property.

                                 ARTICLE 10.
                       ASSIGNMENT AND OFFER TO PURCHASE

     .1  Transfers.

         (a) Neither Member, nor any permitted assignee or successor in
interest of either Member, may Transfer its interest in the Company, or in any
part thereof, or in all or any part of the assets of the Company except as
provided in this Article 10. Except as provided in Subsections 10.1(c),
10.1(d), 10.1(e) or 10.1(f) and for the limited purposes described therein
only, neither Member shall have the right to Transfer less than all of its
Entire Interest.

         (b) Transfer by Prudential of its Entire Interest in the Company to
an Affiliate who is not an individual shall be a Transfer permitted under this
Article 10 and Prudential shall not be required to obtain the consent of, nor
offer its interest to SLG in connection with such a Transfer.

         (c) Without regard to the restrictions imposed by this Article 10
(excepting the obligation set forth in Subsections 10.1(f) and (g)),
Prudential may allocate all or part of its interest in the Company to a
separate account formed by Prudential pursuant to the provisions of Section
17B:28-7 N.J.S.A.

         (d) Neither Member shall permit a Transfer of a fifty percent (50%)
or greater interest in such Member (at any one time or in the aggregate) or
otherwise transfer decision-making authority over, or control of, such Member
to another Person (any such instance, an "Entity Level Transfer"). No
transferee, pursuant to an Entity Level Transfer, shall be entitled to (1)
receive direct distributions or allocations from the Company, (2) have the
right, directly or indirectly, to vote on any matters involving the Company or
this Agreement, (3) be admitted directly as a member of the Company, or (4)
otherwise act, with respect to its interests, in a manner that is likely to
create recourse for, or liability to, the Company.

         (e) If either Member shall Transfer a portion of its Percentage
Interest in the Company as provided in Subsection 10.1(c) that, together with
other interests in the Company Transferred during the preceding twelve (12)
months, represents more than a 49.9% interest in the total profits and capital
of the Company, such Transfer, at either Member's option, shall be effected so
as to avoid a termination of the Company for federal income tax purposes under
Section 708(b)(1)(B) of the Code, and for that purpose the Members agree to
negotiate modifications to this Agreement in good faith.

         (f) Notwithstanding anything to the contrary in this Agreement, under
no circumstances shall (1) the Property be Transferred or any Member be
entitled to Transfer an interest in the Company or effectuate an Entity Level
Transfer if, (i) in the reasonable judgment of either Member, (A) the same
would result in a "prohibited transaction" or (B) the transferee would be a
"party in interest", as such terms are defined in ERISA or any similar
prohibition under applicable law, or (ii) such Transfer or Entity Level
Transfer would result in a default of the terms of the Initial Mortgage Loan
or the Mortgage Loan, as applicable, or otherwise require the making of any
material payment to the Initial Lender or the lender under the Mortgage Loan,
as applicable; or (2) any Member be obligated to sell a percentage interest in
the Company that is greater than forty nine percent (49.9%) of all Percentage
Interests therein.

         (g) In the event of a termination of the Company within the meaning
of Section 708 of the Code because of the dissolution of, or a Transfer of,
any interest in a Member or an entity owning directly or indirectly a
beneficial interest in a Member or a Transfer of a Member's interest in the
Company, such Member shall indemnify the other Member (the "Indemnitee") and
hold the Indemnitee harmless for, from and against any and all net adverse
federal, state or local tax consequences (including any diminution or delay in
any depreciation, recovery or amortization deductions and any and all
penalties, interest, expenses and taxes on payments made pursuant to this
Subsection 10.1(g)) which the Indemnitee shall sustain as a result of such
termination.

         (h) Notwithstanding any provision herein to the contrary, a Transfer
of a fifty percent (50%) or greater interest in SLG Realty or another transfer
of decision-making authority over, or control of, SLG Realty shall be
permitted provided that (1) SLG shall notify Prudential in writing as promptly
as possible, consistent with applicable laws, of any such pending Transfer and
in any event, no later than five (5) Business Days after the effective date of
such a Transfer. The notice shall describe in reasonable detail the pending or
actual Transfer, as the case may be, and shall identify the transferee and its
principals. Prudential shall have the right, exercisable within thirty (30)
days after the later of (i) making such notice or (ii) the actual Transfer, to
initiate the buy-sell procedures pursuant to Section 10.3 without reference to
the restriction imposed by the Interests Transfer Lockout Period. If the
buy-sell procedures are initiated and Prudential is to sell its interest as a
result thereof, SLG shall pay any and all transfer or similar tax that may be
assessed as a consequence of such sale.

     .2  Other  Assignments Void. Any purported  Transfer of an interest in the
Company not otherwise  permitted by this Article 10 shall be null and void.

     .3  Transfer of Entire Interest to Other Member Buy-Sell.

         (a) Either Member (the "Initiating Member") may at any time following
11:59 p.m. on the last day of the thirty ninth (39th) month after the date
hereof (the "Interests Transfer Lockout Period") give the other Member (the
"Non-Initiating Member") a written notice (the "Buy-Sell Notice") of its
desire to purchase the Non-Initiating Member's entire Percentage Interest (the
"Entire Interest"). Such notice shall provide, in reasonable detail, the terms
upon which the Initiating Member shall be willing to purchase the
Non-Initiating Member's Entire Interest, including (1) the value ("Stated
Value") that the Initiating Member places on all the assets of the Company,
and (2) the applicable sales price (the "Buy-Sell Price") for the
Non-Initiating Member's Entire Interest in the Company, which shall be based
on a hypothetical Transfer of the Company for cash at the Stated Value as of
the date of receipt of the Buy-Sell Notice and shall be the amount that the
Non-Initiating Member would receive (excluding repayments of Special Loans and
Emergency Loans, which shall be purchased from the selling Member pursuant to
Subsection 10.7(c)) in a hypothetical liquidation of the Company's assets (in
accordance with the procedures and priorities stated in Article 13) following
such a hypothetical Transfer; provided, however, that, in making such
calculation, it shall be assumed that no reserves are required pursuant to
Subsection 13.5(b) with respect to contingent liabilities and no deduction
from the hypothetical liquidation proceeds shall be made with respect to
transfer and other taxes.

         (b) The Non-Initiating Member shall, on or before the date that is
thirty (30) days after the date of receipt of the Buy-Sell Notice, either (1)
accept the offer of the Initiating Member unconditionally, or (2) deliver its
own Buy-Sell Notice back to the Initiating Member in accordance with this
Section 10.3, but with a Stated Value at least $1,000,000 greater than the
Stated Value in the Buy-Sell Notice it received. If the Non-Initiating Member
fails to respond to the Buy-Sell Notice in strict conformance with this
Section 10.3 and within such thirty (30) day period, the failure to respond
shall be deemed the Non-Initiating Member's election to sell its Entire
Interest to the Initiating Member at the Buy-Sell Price. If the Non-Initiating
Member responds to the Buy-Sell Notice by delivering its own Buy-Sell Notice
to the Initiating Member, then the process described in this Section 10.3
shall commence anew, with the Non-Initiating Member deemed to be the
Initiating Member and the Initiating Member deemed to be the Non-Initiating
Member. Unless and until otherwise agreed in writing, the process shall
continue until an offer is accepted or deemed accepted.

         (c) Upon acceptance or deemed acceptance of an offer pursuant to this
Section 10.3, the Members shall negotiate in good faith to complete the
documents necessary and appropriate to close the transaction, which documents
shall incorporate the following terms:

              (1) The purchase price shall be calculated by the Accountant,
with appropriate adjustments to reflect Company net income or loss from the
date of the accepted Buy-Sell Notice through the closing date;

              (2) Closing shall occur at the office of the selling Member's
counsel no later than ninety (90) days after the Non-Initiating Member's
election, or deemed election, to sell its Entire Interest, or at such other
time or place as may be otherwise agreed to in writing by the Non-Initiating
Member and the Initiating Member;

              (3) There shall be no conditions to the buying Member's
obligation to purchase, including conditions relating to "due diligence" or
"contingencies;"

              (4) There shall be no representations or warranties required of
either party except as to the authority of each Member, and the selling
Member's marketable title to its Entire Interest. The selling Member shall
continue to bear its proportionate liability for claims against the Company
arising from pre-closing acts, omissions, or agreements; and

              (5) Each party shall bear its own attorney's fees in connection
with the transaction. The buying Member shall bear the cost of any title
searches or insurance it elects to purchase. Subject to the provisions of
Subsection 10.7(f), all other expenses of the transaction shall either be
charged to the Company before the closing or shall be shared by the buying
Member and the selling Member in proportion to their Percentage Interests
immediately prior to the closing. No brokerage commission shall be payable by
either party or the Company.

         (d) Notwithstanding any contrary provision of this Section 10.3, if
the original Non-Initiating Member shall purchase the original Initiating
Member's Entire Interest pursuant to a Buy-Sell Notice sent by such
Non-Initiating Member, and such Buy-Sell Notice shall have been received by
the original Initiating Member during the period commencing on the first day
of the fortieth (40th) month after the date hereof and ending on the last day
of the seventy sixth (76th) month after the date hereof (the "Discount
Period"), then the original Non-Initiating Member shall be entitled to
purchase the Initiating Member's Entire Interest at a price equal to
ninety-seven percent (97%) of the Buy-Sell Price as determined by such
procedure.

         (e) In connection with the Transfer of one Member's Entire Interest
to the other Member pursuant to this Section 10.3, all of the provisions of
Subsections 10.7 (b), (c), (d), (e),(f), (g), (h), (i) and (j) shall be
applicable to such Transfer.

     .4  Right of First Refusal.

         (a) Either Member may, at any time, sell its Entire Interest to a
third party; provided that the Member seeking to sell its Entire Interest (the
"Offeror") shall provide a written notice (a "Notice of Offer") to the other
Member (the "Offeree"), which notice shall have attached thereto a copy of an
executed agreement (a "Third Party Contract") relating solely to the proposed
Transfer of the Offeror's Entire Interest. The Third Party Contract shall
provide all of the terms related to the proposed Transfer, including (1) the
identity of the buyer (and, if applicable, the identity of its principals) and
(2) the purchase price to be paid for the Offeror's Entire Interest (the
"Right of First Refusal Price"). The Offeree shall have a period of thirty
(30) days (the "Right of First Refusal Period") from its receipt of a Notice
of Offer to elect to purchase the Offeror's Entire Interest; provided that if
the Offeree shall elect to purchase the Offeror's Entire Interest, and the
Notice of Offer shall have been received during the Discount Period, then the
Offeree shall be entitled to purchase the Offeror's Entire Interest at a price
equal to ninety-seven percent (97%) of the Right of First Refusal Price. If
the Offeree fails to respond to the Notice of Offer on or prior to the
expiration of the Right of First Refusal Period, then the Offeror shall have
the right to consummate the transactions contemplated in the Third Party
Contract in accordance with the terms thereof.

         (b) Upon acceptance of a Notice of Offer pursuant to this Section
10.4, the Members shall negotiate in good faith to complete the documents
necessary and appropriate to close the transaction, which documents shall
incorporate the following terms:

              (1) There shall be no conditions to the buying Member's
obligation to purchase, including conditions relating to "due diligence" or
"contingencies;"

              (2) Closing shall occur at the office of the Selling Member's
counsel at the time set forth in the Third Party Contract, or at such other
time or place as may be otherwise agreed to in writing by the Members;

              (3) There shall be no representations or warranties required of
either party except as to the authority of each Member, and the selling
Member's marketable title to its Entire Interest. The selling Member shall
continue to bear its proportionate liability for claims against the Company
arising from pre-closing acts, omissions, or agreements; and

              (4) Each party shall bear its own attorney's fees in connection
with the transaction. The buying Member shall bear the cost of any title
searches or insurance it elects to purchase. All other expenses of the
transaction shall either be charged to the Company before the closing or shall
be shared by the buying Member and the selling Member in proportion to their
Percentage Interests immediately prior to the closing. No brokerage commission
shall be payable by either party or the Company.

         (c) In connection with the Transfer of one Member's Entire Interest
to the other Member pursuant to this Section 10.4, all of the provisions of
Sections 10.7 (b), (c), (d), (e), (f), (g), (h), (i) and (j) shall be
applicable to such Transfer.

     .5  Transfer of the Property.

         (a) The Property may not be sold during the first four (4) years
following the date hereof (the "Property Transfer Lockout Period") without the
mutual consent of the Members. After the expiration of the Property Transfer
Lockout Period, either Member (the "Seller Member") may give a written notice
("Sales Notice") to the other Member (the "Other Member") of its desire to
sell the Property. The Sales Notice shall provide in reasonable detail the
terms upon which the Seller Member wishes to sell the Property, including the
price for the Property (the "Sales Price"), and shall be accompanied by
computations with respect to each Member setting forth the amount (as to each
Member, the "Interest Value") that each would receive (excluding repayments of
Special Loans and Emergency Loans which would be repurchased from the Seller
Member pursuant to Subsection 10.7(c)) in a hypothetical liquidation of the
Company's assets (in accordance with the procedures and priorities stated in
Article 13) following a hypothetical Transfer of the Property for cash at the
Sales Price as of the date of receipt of the Sales Notice.

         (b) Within thirty (30) days after receiving the copy of the Sale
Proposal, the Other Member may notify (a "Purchase Election Notice") the
Seller Member that it has elected to purchase, on the terms provided in the
Sales Notice, either the Property at the Sales Price or the Seller Member's
Entire Interest at the Interest Value; provided that if the Other Member shall
elect to purchase the Property or the Entire Interest of the Seller Member,
and the Sales Notice shall have been received during the Discount Period, then
the Other Member shall be entitled to purchase, at its option, either (i) the
Property at a price equal to ninety seven percent (97%) of the Sales Price set
forth in the Sales Notice or (ii) the Entire Interest of the Seller Member at
a price equal to ninety-seven percent (97%) of the Interest Value of the
Seller Member. If the Other Member elects to purchase either the Property or
the Seller Member's Entire Interest in accordance with the Sales Notice, then
the Members shall promptly proceed with the Transfer pursuant to this
Subsection 10.5(b), the closing to take place at the office of the Seller
Member's counsel within ninety (90) days following the date of receipt of the
Sales Notice. The provisions of Subsections 10.7(a), (d), (e), (f), (g), (h)
and (i) shall apply to such a Transfer of the Property and the provisions of
Subsections 10.7(b), (c), (d), (e), (f), (g), (h), (i) and (j) shall apply to
such a Transfer of an Entire Interest. All prorations, including real estate
taxes and rents shall be made as of the date of transfer irrespective of
whether the Property or an Entire Interest was conveyed. All real property
transfer taxes shall be paid for by the Company and all recording fees shall
be paid for by the Other Member irrespective of whether the Property or an
Entire Interest was conveyed. Failure of the Other Member to deliver a
Purchase Election Notice within such ninety (90) day period shall be deemed an
election by the Other Member to proceed with a Transfer of the Property (but
not of any Percentage Interests in the Company) to a third party and the
Members shall thereafter use commercially reasonable efforts to sell the
Property to a third party and shall be obligated to do so for a period of nine
(9) months thereafter; provided that such third party shall pay a purchase
price equal to not less than ninety-eight percent (98%) of the Sales Price
(net of legal fees and brokerage commissions).

         (c) If a Transfer to a third party has not been closed within such
nine (9) month period, either Member may elect to remove the Property from the
market, and thereafter the Property may not be offered for Transfer to any
third party prior to reinitiating the process set forth in this Section 10.5.

         (d) During any period of time when either Member or the Company is
actively marketing the Property pursuant to this Section 10.5, neither Member
shall exercise its right to deliver a Buy-Sell Notice pursuant to Section 10.3
except in the circumstances described in Subsection 10.1(h).

     .6   Assumption by Assignee.

         (a) Any Transfer of an Entire Interest in the Company to a third
party pursuant to this Agreement shall be in writing, and shall be a Transfer
of all of the assignor's rights and obligations thereafter accruing hereunder,
and the assignee shall expressly agree in writing to be bound by all of the
terms of this Agreement and assume and agree to perform all of the assignor's
agreements and obligations existing or arising at the time of and subsequent
to such Transfer. Upon any Transfer of the assignor's Entire Interest and
after such assumption, the assignor shall be relieved of its agreements and
obligations hereunder arising after such Transfer and the assignee shall
become a Member in place of the assignor; provided, however, that the
agreements and obligations of the assignor that existed at the time of such
Transfer, including indemnification and other obligations and representations
and warranties contained herein shall survive the Transfer. An executed
counterpart of each such Transfer of an Entire Interest in the Company and
assumption of a Member's obligations thereafter accruing shall be delivered to
each Member and to the Company. The assignee shall pay all expenses incurred
by the Company in admitting the assignee as a Member. Except as otherwise
expressly provided herein, no permitted Transfer shall terminate the Company.

         As a condition to any Transfer of an Entire Interest, the
selling Member shall obtain such consents as may be required from third
parties, if any, or waivers thereof. The other Member shall cooperate with the
selling Member in obtaining such consents or waivers at no expense to the
other Member.

         (b) If a Transfer of either Member's Entire Interest in the Company
shall take place pursuant to the provisions of this Agreement, then unless the
Company is dissolved by such Transfer, the continuing Member on behalf of the
Company promptly thereafter shall take all such actions as may be required by
law to reflect such Transfer.

     .7  General Transfer Provisions. Subsections (b), (c), (d), (e), (f), (g),
(h), (i) and (j) of this Section 10.7 shall apply to the Transfer of one
Member's Entire Interest to the other Member pursuant to Sections 10.3 and 10.4.
Subsections (a), (d), (e), (f), (g), (h) and (i) of this Section 10.7 shall
apply to the Transfer of the Property by the Company to a Member pursuant to
Section 10.5:

         (a) In the event of a Transfer of the Property, the purchase price
shall be paid, at the Company's option, by certified checks or by wire
transfers of immediately available funds to payees as designated by the
Company.

         (b) In the event of the Transfer of an Entire Interest, the purchase
price shall be paid, at the selling Member's option, by certified check drawn
to the order of the selling Member (or as the selling Member shall otherwise
direct), or by wire transfer of immediately available funds to an account or
accounts designated by the selling Member. At the closing of a Transfer of an
Entire Interest, there shall be an adjustment of the purchase price based upon
a proration of any accrued income and expenses pursuant to an accounting of
the Member's books as of the closing date; such accounting shall be audited by
the Accountants within ninety (90) days thereafter. Either Member may require
that a portion of the purchase price equal to the likely post-closing
adjustment (as mutually agreed to by the Members, or as determined by the
Accountants) shall be set aside and placed in escrow with an escrow agent
reasonably acceptable to both Members. The escrow agent shall distribute the
escrowed amount promptly after receipt of, and in accordance with, the
Accountants' audit report. At closing the selling Member shall deliver to the
purchasing Member a "nonforeign affidavit" as referred to in the Foreign
Investment in Real Property Tax Act in form and substance reasonably
satisfactory to the purchasing Member together with original counterparts or
certified copies of all leases and service contracts affecting the Property.

         (c) If there are any outstanding Special Loan(s) or Emergency Loan(s)
by the selling Member to the Company, such Special Loan(s) or Emergency
Loan(s), including accrued and unpaid interest thereon, shall be purchased by
the purchasing Member for the full amount outstanding as a condition precedent
to such Transfer. The purchase price for such Special Loan(s) or Emergency
Loan(s) shall be paid, at the selling Member's option, by certified check
drawn to the order of the selling Member, or by wire transfer of immediately
available funds to an account designated by the selling Member. At the
closing, the selling Member shall deliver to the purchasing Member each note
evidencing such Special Loan(s) or Emergency Loan(s).

         (d) On payment of the purchase price, the purchasing Member shall, at
its option, as to each Company debt, obligation or claim against the Company
for which the selling Member is or may be personally liable (except for any
debts, obligations or claims that are fully insured by the public liability
insurer(s) of the Company or another public liability insurer(s) acceptable to
the selling Member), elect one of the following options: (1) obtain a release
of the selling Member from all liability, direct or contingent, by all holders
of each such Company debt, obligation or claim, (2) cause the same to be paid
in full at the closing to the satisfaction of the selling Member, or (3)
obtain an indemnity in form and substance acceptable to Selling Member
indemnifying selling Member against claims that are not released or paid. In
addition, the purchasing Member shall defend, indemnify and hold the selling
Member harmless for, from and against any tort liability not insured against
by the Member's general comprehensive insurance policies (other than those
tort liabilities which are uninsurable) and which liability of the selling
Member is based solely on its status as a Member with respect to the Property;
provided, however, that such indemnification shall not extend to those claims
arising in whole or in part from intentional acts or omissions or negligence
proximately caused by the selling Member. If there are any Guaranty
Reimbursement Obligations owing to Prudential under the Limited Guaranty
Agreement, the same shall be fully satisfied as a condition precedent to any
Transfer. Thereafter, both Members shall execute a mutual general release
pursuant to which each shall waive and release the other from all liabilities
and obligations (whether known or unknown, foreseen or unforeseen or
previously accrued or thereafter accruing) relating to each Member's Entire
Interest or the Property, other than those arising from the indemnities given
pursuant to this Subsection 10.7(d).

         (e) Following the giving of the Buy-Sell Notice pursuant to Section
10.3 or the Notice of Offer pursuant to Section 10.4 or the Sales Notice
pursuant to Section 10.5 in connection with a proposed Transfer to a Member
and until the closing thereof, all Members (including the selling Member)
shall continue to be entitled to distributions of Operating Cash Flow from the
Company in accordance with Subsection 9.2(a). Pending the closing of such
Transfer, neither Member shall be entitled to distributions of Extraordinary
Cash Flow, if any, in accordance with Subsection 9.2(b), provided however, if
such closing does not occur within the time period provided therefor in
Section 10.3, 10.4 or 10.5, as applicable, both Members shall be entitled to
any distribution of Extraordinary Cash Flow in accordance with Subsection
9.2(b).

         (f) If the Property is damaged by fire or other casualty, or if any
entity possessing the right of eminent domain shall give notice of an
intention to take or acquire a substantial part of the Property, and such
damage occurs, or such notice is given between the date of the giving of the
Buy-Sell Notice pursuant to Section 10.3 or the Notice of Offer pursuant to
Section 10.4, or the Sales Notice pursuant to Section 10.5 and the closing
date of the purchase of an interest in the Company or the purchase of the
Property, the Members shall be required to complete the transaction and the
purchasing Member shall accept the Property in an "as is" condition and in
lieu of any reduction in purchase price shall accept an assignment of any
insurance or condemnation proceeds or an allocable portion thereof.

         (g) At the closing of a Transfer of the Property, the Members shall
both execute and deliver a warranty deed with covenants against grantor's acts
in recordable form, a bill of sale to the purchaser of all of the assets of
the Company and Transfers to the purchaser of any and all leases or service
contracts affecting the Property. In the case of the Transfer of an Entire
Interest, the selling Member shall execute an assignment of its Entire
Interest, free and clear of all liens, encumbrances and adverse claims, which
assignment shall otherwise be in form and substance reasonably satisfactory to
the purchasing Member, and such other instruments as the purchasing Member
shall reasonably require to Transfer the Entire Interest of the selling Member
to such Person as the purchasing Member may designate. Such documents shall be
prepared by the purchasing Member and closing costs and all other charges
involved in closing the Transfer (except for attorneys' fees (each party
paying their own) and title insurance costs (to be paid by the purchaser))
shall be prorated between the Members in the ratio of their respective
Percentage Interests. Stamp, recording, transfer or similar taxes arising in
connection with the Transfer of the Entire Interest, if any, shall be paid by
the selling Member, and such taxes shall be paid by Company in connection with
a Transfer of the Property.

         (h) The Company shall be dissolved as of the closing date of a
Transfer of the Property, and on the closing date the Members shall file, or
cause to be filed, a written certificate of cancellation with the Delaware
Secretary of State in accordance with Act Section 18-203 and such other
documents as shall be necessary or desirable to effectuate such dissolution.
The Members shall cooperate in taking all steps necessary in connection with
the dissolution of the Company. In the case of the Transfer of an interest in
the Company, the Company shall not be dissolved, but the Members will execute
and file on the closing date such amendment to the Certificate of Formation as
may be appropriate to reflect the change in the identity of the Members.

         (i) It is the intent of the parties to this Agreement that the
requirements or obligations, if any, of one Member to sell its Entire
Interest, or to join in the conveyance by the Company of the Property in
accordance with the provisions of Sections 10.3, 10.4 or 10.5 shall be
enforceable by an action for specific performance of a contract relating to
the purchase of real property or an interest therein. If the selling Member
shall have created or suffered any unauthorized liens, encumbrances or other
adverse interest against either the Property or the selling Member's interest
in the Company, the purchasing Member shall be entitled either to an action
for specific performance to compel the selling Member to have such defects
removed, in which case the closing shall be adjourned for such purpose, or, at
the purchasing Member's option, to an appropriate offset against the purchase
price.

         (j) In the event of the purchase of the Entire Interest of one Member
by the other Member, at the option of the purchasing Member, the Entire
Interest of the selling Member will be transferred to a nominee of the
purchasing Member.

     .8  Indemnification for Securities Laws Violations.

         (a) SLG acknowledges that any Transfer of a direct or indirect
interest in SLG may constitute or involve an offering or Transfer of
securities for purposes of the Securities Act of 1933, the Securities and
Exchange Act of 1934 and under applicable state securities laws. All such
federal and state securities laws which may have application to any such
transfers are referred to herein as the "Securities Laws."

         (b) If any Transfer of a direct or indirect interest in SLG shall be
caused by or on behalf of SLG or any of its Affiliates, SLG shall be fully
liable and responsible to Prudential for any and all liability, loss, cost,
injury, damage or expense suffered or incurred by Prudential resulting from
violations of any Securities Laws occurring in connection with such transfer;
provided, however, that Prudential shall be responsible and liable to SLG for
any and all liability, loss, cost, injury, damage or expense suffered or
incurred by SLG resulting from any violation or breach of any Securities Laws
occurring in connection with such Transfer based upon false or misleading
information that is furnished in writing by Prudential in connection with such
Transfer by SLG or any Member therein.

         (c) SLG shall indemnify, defend and hold Prudential and its
Affiliates free and harmless for, from and against any and all liability,
loss, cost, injury, damage or expense (including, without limitation,
attorneys' fees and costs incurred in the investigation, defense and
settlement of the matter) suffered or incurred by reason of any breach by
SLG of its obligations under this Subsection 10.8(b).

     .9  Compliance with ERISA.

         (a) Not less than five (5) Business Days before any direct Transfer
in SLG or any indirect Transfer in SLG (but only if such indirect Transfer
results from a Transfer of (1) a fifty percent (50%) or greater interest in
any Person (at any one time or in the aggregate other than transfers of shares
in SL Green Realty Corp. made in the ordinary course of business to or from
non-Affiliates) or (2) decision-making authority over, or control of, such
Person) SLG shall cause the proposed transferee to deliver to Prudential a
certification in substantially the form of Exhibit D.

         (b) Prudential shall deliver to SLG a certification in substantially
the form of Exhibit E attached hereto and made a part hereof on the closing or
consummation of each of the following transactions: (1) an Emergency Loan or
Special Loan; (2) a decrease of a Member's Percentage Interest pursuant to
Subsection 4.5(d) hereof; and (3) a Transfer pursuant to Section 10.3 or 10.4.

         (c) If there is a proposed Transfer of the Property pursuant to
Section 10.5, and either Prudential or SLG buys the Property, then, at the
closing of the Transfer, (1) SLG shall deliver to Prudential a certification
in substantially the form of Exhibit D, and (2) Prudential shall deliver to
SLG a certification in substantially the form of Exhibit E.

         (d) Anything else in this Agreement to the contrary notwithstanding,
Prudential shall have up to thirty (30) days following the receipt by it of a
certification by SLG or a proposed transferee provided for in this Section
10.9 to notify SLG that it has determined that a proposed Transfer by SLG of
its Entire Interest or a proposed Transfer of the Property would result in a
Plan Violation. If Prudential notifies SLG that any such proposed transaction
would constitute a Plan Violation (which notification shall contain an
explanation of the reasons for such determination), the proposed transaction
shall not be consummated and any attempt to do so shall be void. If, within
such thirty (30) day period, Prudential notifies SLG that it has determined
that no Plan Violation will result from the proposed transaction, or if
Prudential does not deliver any notification to SLG within such thirty (30)
day period, then the proposed transaction may be consummated; provided,
however, that such transaction must be consummated no later than (1) the
twentieth (20th) day after the delivery to SLG by Prudential of a notice that
it has determined that the proposed transaction will not result in a Plan
Violation or the expiration of the thirty (30) day period referred to in this
Subsection 10.9(d), as the case may be, or (2) if the applicable Section of
this Agreement provides for a closing that is later than such twenty (20) day
period, the latest day that such Section permits such closing to occur; and
provided, further, that, if any certification by SLG or a proposed transferee
contains a material misrepresentation or omission, then, in such event,
notwithstanding Prudential's lack of objection or deemed lack of objection
thereto, the proposed transaction shall not be consummated and, if it is
consummated, such transaction shall be void. Each (i) breach of representation
or warranty given in connection with this Section 10.9, and (ii) violation of
Sections 2.10(a)(5), this Section 10.9, or any other provision of this
Agreement relating to ERlSA or Plan Violations will constitute a default
entitling the Nondefaulting Member to terminate this Agreement pursuant to
Subsection 12.1(c).

         (e) SLG shall indemnify Prudential and defend and hold Prudential
harmless from and against all loss, cost, damage and expense that Prudential
may incur, directly or indirectly, as a result of a (1) default, or (2) a
breach of a representation or warranty given by SLG or any Affiliate of SLG
under this Section 10.9, or (3) any material misstatement or omission in a
certification by SLG or proposed transferee of SLG which is given to
Prudential pursuant to this Section 10.9. The loss, cost, damage and expense
will include, without limitation, attorney's fees and costs incurred in the
investigation, defense and settlement of claims and losses incurred in (i)
correcting any Plan Violation, (ii) the Transfer of a prohibited Company
interest, or (iii) obtaining any individual exemption for a Plan Violation
that may be required, in Prudential's sole discretion. This indemnity shall
survive (A) the Transfer of the Property or of SLG's Entire Interest and (B)
termination of this Agreement. SLG shall not be required to indemnify
Prudential pursuant to this Subsection 10.9(e) if any of Prudential's
representations and warranties relating to ERISA or Plan Violations are
materially false.

         (f) The Company will not enter into any agreements or suffer any
conditions that Prudential reasonably determines would result in a Plan
Violation. At SLG's request, Prudential shall deliver a notice of each such
determination to SLG together with an explanation of the reasons for the
determination.

         (g) Prudential and SLG will cooperate to monitor and correct Plan
Violations.

                                 ARTICLE 11.
                     DISSOLUTION OR BANKRUPTCY OF A MEMBER

     .1  Dissolution or Merger. If either Member shall be dissolved or merged
with or consolidated into another Person, or if all or substantially all of its
assets shall be Transferred, then unless such dissolution, merger,
consolidation, or Transfer is expressly permitted under Article 10, such
dissolution, merger, consolidation or Transfer shall, at the option of the
other Member, be a dissolution of the Company, and the other Member shall be
the Liquidating Member in the dissolution of the Company. The other Member's
option shall be effective as of the date of such dissolution, merger,
consolidation or Transfer and the option shall be exercised, if at all, within
sixty (60) days after the other Member receives notice in writing of such
dissolution, merger, consolidation or Transfer.

     .2 Bankruptcy, etc. If:

         (a) either Member or any general partner in a Member or any general
partner in a general partner in a Member ("General Partner"), if such Member
is a partnership, or any managing member in a Member or any managing member in
a managing member in a Member ("Managing Member"), if such Member is a limited
liability company, or any successor in interest thereto shall take, permit or
acquiesce in an Insolvency Action with respect to Member, General Partner or
Managing Member; or

         (b) a court of competent jurisdiction shall enter an order, judgment
or decree approving a petition filed against either Member, or against any
General Partner, or against any Managing Member, seeking any reorganization,
arrangement, composition, readjustment, liquidation, dissolution or similar
relief under the present or any future federal bankruptcy code or any other
present or future applicable federal, state or other statute or law relating
to bankruptcy, insolvency, or other relief for debtors, and such Member, or
any General Partner, or any Managing Member, shall acquiesce in the entry for
such order, judgment or decree (the term "acquiesce" includes but is not
limited to the failure to file a petition or motion to vacate or discharge
such order, judgment or decree within thirty (30) days after the entry of the
order, judgment or decree) or such order, judgment or decree shall remain
unvacated and unstayed for an aggregate of ninety (90) days (whether or not
consecutive) from the date of entry thereof, or any trustee, receiver,
conservator or liquidator of said Member, or any General Partner, or any
Managing Member, or of all or any substantial part of said Member's or General
Partner's or Managing Member's property or its interest in the Company shall
be appointed without the consent or acquiescence of said Member, or such
General Partner, or such Managing Member, and such appointment shall remain
unvacated and unstayed for an aggregate of sixty (60) days (whether or not
consecutive); then such event shall cause the dissolution of the Company and
the other Member shall be the Liquidating Member.

                                 ARTICLE 12.
                                    DEFAULT

     .1  Defaults. If either Member fails to perform any of its obligations
hereunder or under any agreement or instrument delivered pursuant hereto, or
breaches any of the terms, conditions or covenants contained in any of the
foregoing, (other than the obligation to make Additional Capital Contributions
specified in Section 4.5) then the other Member (the "Nondefaulting Member")
shall have the right to give such party (the "Defaulting Member") a notice of
default ("Notice of Default"). The Notice of Default shall set forth the
nature of the obligation giving rise to the default.

         (a) If such default is neither a failure to pay money nor a default
with respect to the representations contained in Section 2.10 (for which no
cure period shall apply) and if, within the thirty (30) day period following
receipt of the Notice of Default, the Defaulting Member in good faith
commences to perform such obligation and cure such default and thereafter
prosecutes to completion with diligence and continuity the curing thereof and
cures such default within a reasonable time (but no later than one year), then
it shall be deemed that the Notice of Default was not given and the Defaulting
Member shall lose no rights hereunder. If, within such thirty (30) day period,
the Defaulting Member does not commence in good faith the curing of such
default or does not thereafter prosecute to completion with diligence and
continuity the curing thereof when and as required by the preceding sentence,
then the Nondefaulting Member shall have the rights set forth in Subsection
12.1(c).

         (b) If such default is a failure to pay money when required, and if
such sums of money shall be paid within forty-five (45) days after the date
such money is due, together with any additional costs that the Company and/or
the Nondefaulting Member may have incurred because the sums were not paid when
due (payment of such additional costs shall not be credited to the Defaulting
Member's Capital Account or count as a contribution to such Capital Account)
then it shall be deemed that such Notice of Default was not given and the
Defaulting Member shall lose no rights hereunder. If such sums are not so paid
within such forty-five (45) day period, the Nondefaulting Member shall have
the rights set forth in Subsection 12.1(c).

         (c) If any default is not cured as set forth in Subsection 12.1(a) or
12.1(b), the Nondefaulting Member, by giving the Defaulting Member written
notice thereof within ninety (90) days of the expiration of the respective
cure periods provided in Subsection 12.1(a) or 12.1(b), may treat such default
as a dissolution of the Company, and the Nondefaulting Member shall be the
Liquidating Member with the rights provided in Article 13 including the right
to deliver a Demand Notice to the Defaulting Member; provided, however, that
if such default is cured prior to the delivery of any notice provided for in
this Subsection 12.1(c), then it shall be deemed that such notice may not be
given and the Defaulting Member shall lose no rights hereunder.

     .2  Negation of Right to Dissolve by Will of Member. Except as set forth in
Articles 10 and 11 and in Section 12.1, neither Member shall have the right to
terminate this Agreement or dissolve the Company by its express will or by
withdrawal without the consent of the other Member. Upon any dissolution
occurring by operation of law or caused by the express will or withdrawal of
one of the Members in contravention of this Agreement, the Member not causing
the dissolution shall be the Liquidating Member.

     .3  Not Exclusive  Remedy.  The rights granted in Section 12.1 shall not be
deemed an exclusive  remedy of the Nondefaulting Member, but all other rights
and remedies, legal and equitable, shall be available to it.

     .4  Waiver of Right of Partition. The Members agree that each part of the
Improvements is an integrated unit of the Property, and it would be unfeasible
and detrimental to the Property to have it partitioned, and therefore each
Member does hereby waive any claim or right to petition any court for
partition of the Property.

                                  ARTICLE 13.
                                  DISSOLUTION

     .1  Winding Up by Members. Upon dissolution of the Company by operation of
law, by any provision of this Agreement or by agreement between the Members,
the Company's business shall be wound up and all its assets distributed in
liquidation. In such dissolution, except as otherwise expressly provided in
Articles 10, 11 and 12, the Members shall be co-liquidating Members and shall
continue to act through the Committee. In such event, the Members shall have
equal rights to wind up the Company and shall proceed to cause the Company's
property to be sold and to distribute the proceeds of Transfer as provided in
Section 13.5. Except with respect to (a) all assets on which a single,
non-severable mortgage or other lien will be in effect after such
distribution, and (b) any assets the Members shall determine are not readily
severable or distributable in kind, the Members, to the extent that
liquidation of such assets is not required to fulfill the payments, if any,
under Subsections (a), (b), (c) and (d) of Section 13.5, shall have the right
to distribute, in kind, undivided interests in all or a portion of the assets
of the Company to the Members pro rata as tenants in common in accordance with
Subsection 13.5(e).

     .2  Winding Up by Liquidating Member. In a dissolution pursuant to the
occurrences of events described in any of Articles 10, 11 or 12, the
Liquidating Member shall be as therein provided and such Liquidating Member
shall have the right to wind up the Company and cause the Company's assets to
be sold and the proceeds of Transfer distributed as provided in Section 13.5.

     .3  Offset for Damages. In the event of dissolution resulting from an event
described in Article 11 or 12, the Liquidating Member shall be entitled to
deduct from the amount payable to the other Member pursuant to Subsection
13.2(a) or (b), Subsection 13.4 or Section 13.5 the amount of damages incurred
by the Liquidating Member proximately resulting from any such event.

     .4  Distributions of Operating Cash Flow. Subject to the provisions of
Section 10.7, upon the dissolution of the Company for any reason, during the
period of liquidation and until termination of the Company, the Members shall
continue to receive the Operating Cash Flow and to share profits and losses
for all tax and other purposes as provided in Article 9 of this Agreement.

     .5  Distributions  of Proceeds of Liquidation.  The proceeds of
liquidation  shall be applied in the following order of priority:

         (a) First. To the payment of: (1) debts and liabilities of the
Company except: (i) Special Loans, Emergency Loans or Loans that may have been
made by either of the Members to the Company, and (ii) debts secured by lien
on property sold subject thereto, provided that neither the Company nor either
of the Members shall be personally liable on, or they shall be released from,
such debts, and (2) expenses of liquidation;

         (b) Second. To the setting up of any reserves that the Liquidating
Member or Members, as the case may be, may reasonably deem necessary for any
contingent or unforeseen liabilities or obligations of the Company or of the
Members arising out of or in connection with the Company. Any such reserves
shall be deposited by the Company in a bank or trust company acceptable to the
Liquidating Member or Members, as the case may be, as escrow agent, to be held
by it for the purpose of disbursing such reserves in payment of any of the
aforementioned liabilities or obligations, and at the expiration of such
period as the Liquidating Member or Members, as the case may be, shall
reasonably deem advisable, distributing the balance, if any, thereafter
remaining, in a manner hereinafter provided;

         (c) Third. To the repayment of unpaid principal and accrued and
unpaid interest on any Emergency Loans, but if the amount available for such
repayment shall be insufficient to repay all Emergency Loans, then repayment
shall be made in the same manner as provided in Section 5.2;

         (d) Fourth. To the repayment of unpaid principal and accrued and
unpaid interest on any Special Loans that may have been made by either of the
Members, but if the amount available for such repayment shall be insufficient
to repay all Special Loans, then repayment shall be made in the manner
provided in Section 5.2;

         (e) Fifth. After making all applicable allocations to the Members'
Capital Accounts as provided in Article 9, to the Members in accordance with
positive Capital Account balances.

     .6  Orderly  Liquidation.  A  reasonable  time shall be allowed for the
orderly  liquidation  of the assets of the Company and the  discharge  of
liabilities  to  creditors  so as to enable the Members to minimize  the losses
normally attendant upon a liquidation.

     .7  Financial  Statements.  During the period of winding  up, all the
financial  statements  provided  for in Section 7.1 shall continue to be
prepared and furnished to the Members.

     .8  No Restoration of Deficit Capital Accounts. At no time during or after
the term of the Company shall a Member with a deficit balance in its Capital
Account have any obligation to the Company or to another Member or to any

irrevocably waives any objection, including any objection of the laying of
venue or based on the grounds of forum non conveniens (provided that the
action or proceeding in question is brought in New York County, New York),
that it may now or hereafter have to the bringing of any such action or

i.e., the exercise of one or more of the provisions hereof,  unless
specifically stated to the contrary, shall not preclude the exercise of any
other provisions hereof.

     .6  Severability. In the event of invalidity of any provision of this

other Person.

     .9  Waiver, etc. The failure of either of the Members to at any time
enforce any of the provisions of this Agreement or any agreement or instrument
delivered pursuant hereto or to give any notice of default thereunder, shall
not be deemed or construed to be a waiver of any such provision, nor to in any
way affect the validity of this Agreement or any agreement or instrument
delivered pursuant hereto or any provision hereof or the right of either of
the Members to thereafter enforce each and every provision of this Agreement
(including the provisions of Article 12) and each agreement and instrument
delivered pursuant hereto. No waiver of any breach of any of the provisions of

with the breach by Prudential of any misrepresentation, warrantee or covenant
made by it in this Agreement or in any agreement or instrument pursuant
hereto.

Each Member agrees to indemnify the other Member and the Company and hold them
each harmless from and against all liability, loss, cost, damage and expense
(including attorneys' fees and costs incurred in the investigation, defense

suffer or incur by reason of any claim for brokerage fees or commissions
arising as a result of a breach of the foregoing representation.

represents and warrants to you, in order to comply with the Employment
Retirement Income Security Act of 1974, as amended ("ERISA"), that:

                  (1) the source of funds from which Prudential [has
purchased/is purchasing] [its interest in the Company/the Property] is its

84-14");

                  (2)  Prudential  is a qualified  professional  asset manager

                  (3) the terms of [Prudential's acquisition of its interest
in the Company] [the transaction described in the first paragraph of this

understanding designed to benefit a party in interest (in satisfaction of the
conditions of Part I(c) of PTE 84-14);

                  (4) the  transaction  contemplated  hereunder is not

         (vii) All of Borrower's right, title and interest in the proceeds

awards resulting from a change of any streets (whether as to grade, access, or
otherwise) and for severance damages, including the right to make, enter into
and apply the proceeds of any settlements, judgments or compromises;

         (viii) All tax refunds, including interest thereon, tax rebates, tax
credits, and tax abatements, and the right to receive the same, which may be
payable or available with respect to the Property;

         (ix) All leasehold estates, ground leases, leases, subleases,
licenses, or other agreements affecting the use, enjoyment or occupancy of the
Property now or later existing (including any use or occupancy arrangements
created pursuant to Title 7 or 11 of the United States Code, as amended from
time to time, or any similar federal or state laws now or later enacted for
the relief of debtors (the "Bankruptcy Code") and all extensions and
amendments thereto (collectively, the "Leases") and all Borrower's right,
title and interest under the Leases, including all guaranties thereof and
other security or credit enhancement rights or instruments;

         (x) All rents, issues, profits, royalties, receivables, use and
occupancy charges (including all oil, gas or other mineral royalties and
bonuses), income and other benefits now or later derived from any portion or
use of the Property (including any payments received with respect to any
Tenant or the Property pursuant to the Bankruptcy Code) and all cash, security
deposits, advance rentals, or similar payments relating thereto (collectively,
the "Rents") and all proceeds from the cancellation, termination, surrender,
sale or other disposition of the Leases, and the right to receive and apply
the Rents to the payment of the Obligations; and

         (xi) The right, in the name and on behalf of Borrower, to appear in
and defend any action or proceeding brought with respect to the Property, and
to commence any action or proceeding to protect the interests of Lender in the
Property.

B. Assignment of Rents. Borrower hereby absolutely and unconditionally
assigns, sets over, and transfers to Lender all of Borrower's right, title,
interest and estates in and to the Leases and the Rents, subject to the terms
and license granted to the Borrower under that certain Assignment of Leases
and Rents made by Borrower to Lender dated the same date as this Instrument
(the "Assignment"), which document shall govern and control the provisions of
this assignment.

C. Outstanding Indebtedness. The aggregate outstanding indebtedness evidenced
by the Note and secured by this Instrument is in the amount of One Hundred
Twelve Million Dollars ($112,000,000.00), it being understood that no interest
under the Note is accrued and unpaid for the period prior to the date hereof,
but that interest shall accrue from and after the date hereof at the rate or
rates provided in the Note.

D. Mortgage Consolidation. The Existing Mortgage and the liens thereof, as
spread in accordance with Section A above, is hereby combined and consolidated
so that together they shall hereafter constitute in law but one mortgage, a
single lien, covering the Property and securing the aggregate principal sum of
One Hundred Twelve Million Dollars ($112,000,000.00), together with interest
thereon as provided in the Note (the Existing Mortgage, as so spread, combined
and consolidated and restated pursuant to the provisions of this Agreement,
being herein collectively referred to as the "Instrument").

E. Ratification of Note. The Note is hereby ratified and confirmed in all
respects by Borrower. All principal, interest and other sums of any nature
that may or shall become due and payable pursuant to the provisions of the
Note shall, subject to the limitations set forth in Section 1.03, constitute
part of the Obligations (defined below) secured by this Instrument.

F. No Release or Novation. This Agreement constitutes a spreader,
consolidation and modification of the Existing Mortgage and is not intended to
and shall not extinguish any of the indebtedness of Borrower under the
Existing Note, the Existing Mortgage or any other document or instrument
executed and delivered in connection therewith in such a manner as would
constitute a release or novation of the original indebtedness or obligations
of Borrower under the Existing Note, the Existing Mortgage or any of such
other documents or instruments, nor shall this Agreement affect or impair the
priority of any liens created thereby, it being the intention of the parties
hereto to preserve all liens and security interests securing payment of the
Existing Note, which liens and security interests are acknowledged by Borrower
to be valid and subsisting against the Property and any other security or
collateral for the Obligations.

G. Certain Representations. Borrower represents and warrants (i) that there
are no offsets, counterclaims or defenses against the indebtedness evidenced
by the Note or against the enforcement of this Agreement, the Instrument or
the Note, (ii) that Borrower, and the undersigned representative of Borrower,
has full power, authority and legal right to execute this Agreement and to

Borrower, and (iv) that Borrower has no claims, counterclaims or offsets of
any nature whatsoever against Lender or any previous holder of the

                  ARTICLE II - REPRESENTATIONS AND WARRANTIES

Borrower hereby represents and warrants to Lender as follows:

Section 2.01 Legal Status and Authority. Borrower (a) is a Delaware limited
liability company duly organized, validly existing, and in good standing and
qualified to transact business under the laws of its state of organization
("Organization State") and the State of New York; and (b) has all necessary
approvals, governmental and otherwise, and full power and authority to own its
properties (including the Property) and carry on its business.

Section 2.02 Validity of Documents. The execution, delivery and performance of
the Documents and the borrowing evidenced by the Note (a) are within the power
of Borrower and its members; (b) have been authorized by all requisite action;
(c) have received all necessary approvals and consents; (d) will not violate,
conflict with, breach, or constitute (with notice or lapse of time, or both) a
default under (i) any law, order or judgment of any court, governmental
authority, or the governing instrument of Borrower or its members or (ii) any
indenture, agreement, or other instrument to which Borrower is a party or by
which it or any of its property is bound or affected; (e) will not result in
the creation or imposition of any lien, charge, or encumbrance upon any of its
properties or assets except for those in this Instrument; and (f) will not
require any authorization, approval or license on the part of Borrower or its
members from, or any filing with, any governmental or other body (except for
the recordation of this Instrument and Uniform Commercial Code ("U.C.C.")
filings). The Documents constitute legal, valid, and binding obligations of
Borrower and its members (as applicable).

Section 2.03 Litigation. There is no action, suit, or proceeding, judicial,
administrative, or otherwise (including any condemnation or similar
proceeding), pending or, to the actual knowledge of Borrower, threatened or
contemplated against, or affecting, Borrower that would have a material
adverse affect on Borrower's ability to perform its obligations.

Section 2.04  Intentionally Omitted.

Section 2.05 Tax Status of Borrower. Borrower is not a "foreign person" within
the meaning of Sections 1445 and 7701 of the Internal Revenue Code of 1986, as
amended, and the regulations thereunder.

Section 2.06 Bankruptcy and Equivalent Value. No bankruptcy, reorganization,
insolvency, liquidation, or other proceeding for the relief of debtors has
been instituted by or against Borrower or any manager or managing member of
Borrower. Borrower has received reasonably equivalent value for granting this
Instrument.

Section 2.07 Disclosure. Borrower has disclosed to Lender all material facts
and has not failed to disclose any material fact that could cause any
representation or warranty made herein to be materially misleading. There has
been no adverse change in any condition, fact, circumstance, or event that
would make any such information materially inaccurate, incomplete or otherwise
misleading.

Section 2.08 Illegal Activity. No portion of the Property has been or will be
purchased, improved, fixtured, equipped or furnished with proceeds of any
illegal activity by Borrower.

                    ARTICLE III - COVENANTS AND AGREEMENTS

Borrower covenants and agrees with Lender as follows:

Section 3.01 Payment of Obligations and Defense of Liens. Borrower shall (a)
timely pay and cause to be performed the Obligations and (b) warrant and
defend the validity, enforceability and priority of the lien and security
interests created by this Instrument against all Persons.

Section 3.02 Continuation of Existence. Borrower shall not (a) dissolve,
terminate, or otherwise dispose of, directly, indirectly or by operation of
law, all or substantially all of its assets; (b) reorganize or change its
legal structure without Lender's prior written consent; (c) change its name,
address, or the name under which Borrower conducts its business without
promptly notifying Lender; or (d) do anything to cause the representations in
Section 2.02 to become untrue.

Section 3.03  Taxes and Other Charges.

         (a) Payment of Assessments. Borrower shall pay when due and prior to
the date any fine, penalty, interest or charge for nonpayment may be imposed,
all taxes, liens, assessments, utility charges (public or private and
including sewer fees), ground rents, maintenance charges, dues, fines,
impositions, and public and other charges of any character (including
penalties and interest) assessed against, or which could become a lien
against, the Property ("Assessments"). Unless Borrower is making deposits per
Section 3.10, Borrower shall provide Lender with receipts evidencing such
payments (except for income taxes, franchise taxes, ground rents, maintenance
charges, and utility charges) within sixty (60) days after their due date.

         (b) Right to Contest. So long as no Event of Default (defined below)
is continuing, Borrower may, prior to delinquency and at its sole expense,
contest any Assessment, but this shall not change or extend Borrower's
obligation to pay the Assessment as required above unless (i) Borrower gives
Lender prior written notice of its intent to contest an Assessment; (ii)
Borrower demonstrates to Lender's reasonable satisfaction that (A) the
Property will not be sold to satisfy the Assessment prior to the final
determination of the legal proceedings, (B) it has taken such actions as are
required or permitted to accomplish a stay of any such sale, or (C) it has
furnished a bond or surety (reasonably satisfactory to Lender in form and
amount) sufficient to prevent a sale of the Property; (iii) at Lender's
option, Borrower has deposited the full amount necessary to pay any unpaid
portion of the Assessments with Lender (provided that Lender shall not require
such a deposit if Lender or its Affiliate, in its capacity as a member of
Borrower, has consented in writing to such contest); and (iv) such proceeding
shall be permitted under any other instrument to which Borrower or the
Property is subject (whether superior or inferior to this Instrument);
provided, however, that the foregoing shall not apply to the contesting of any
income taxes, franchise taxes, ground rents, maintenance charges, and utility
charges.

         (c) Documentary Stamps and Other Charges. Borrower shall pay all
taxes, assessments, charges, expenses, costs and fees, including registration
and recording fees and revenue, stamp, intangible, and any similar taxes
(collectively, the "Transaction Taxes") required in connection with the making
and/or recording of the Documents. If Borrower fails to pay the Transaction
Taxes promptly after demand therefor, Lender may (but is not obligated to) pay
these and Borrower shall reimburse Lender on demand for any amount so paid
with interest at the applicable interest rate specified in the Note, which
shall be the Default Rate unless prohibited by Laws. All such sums paid by
Lender shall, subject to the limitations in Section 1.03, be secured by this
Instrument.

         (d) Changes in Laws Regarding Taxation. If any law (a) deducts from
the value of real property for the purpose of taxation any lien or encumbrance
thereon, (b) taxes mortgages or debts secured by mortgages for federal, state
or local purposes or changes the manner of the collection of any such existing
taxes, and/or (c) imposes a tax, either directly or indirectly, on any of the
Documents or the Obligations, Borrower shall, if permitted by law, pay such
tax within the statutory period or within thirty (30) days after demand by
Lender, whichever is less; provided, however, that if, in the reasonable
opinion of Lender, Borrower is not permitted by law to pay such taxes, Lender
shall have the option to declare the Obligations immediately due and payable
upon ninety (90) days' notice to Borrower.

         (e) No Credits on Account of the Obligations. Borrower will not claim
or be entitled to any credit(s) on account of the Obligations for any part of
the Assessments and no deduction shall be made or claimed from the taxable
value of the Property for real estate tax purposes by reason of the Documents
or the Obligations. If such claim, credit or deduction is required by law,
Lender shall have the option in its reasonable discretion to declare the
Obligations immediately due and payable upon ninety (90) days' notice to
Borrower.

Section 3.04 Defense of Title, Litigation, and Rights under Documents.
Borrower shall forever warrant, defend and preserve Borrower's title to the
Property, the validity, enforceability and priority of this Instrument and the
lien or security interest created thereby, and any rights of Lender under the
Documents against the claims of all persons, and shall promptly notify Lender
of any such claims. Lender (whether or not named as a party to such
proceedings) is authorized and empowered (but shall not be obligated) to take
such additional steps as it may deem necessary or proper for the defense of
any such proceeding or the protection of the lien, security interest,
validity, enforceability, or priority of this Instrument, title to the
Property, or any rights of Lender under the Documents, including the
employment of counsel, the prosecution and/or defense of litigation, the
compromise, release, or discharge of such adverse claims, the purchase of any
tax title, the removal of any such liens and security interests, and any other
actions Lender deems necessary to protect its interests. Borrower authorizes
Lender to take any actions required to be taken by Borrower, or permitted to
be taken by Lender, in the Documents in the name and on behalf of Borrower.
Borrower shall reimburse Lender on demand for all expenses (including
reasonable attorneys' fees) incurred by it in connection with the foregoing
and Lender's exercise of its rights under the Documents. All such expenses of
Lender, until reimbursed by Borrower, shall be part of the Obligations, bear
interest at the applicable interest rate specified in the Note, which shall be
the Default Rate unless prohibited by Laws, and shall be secured by this
Instrument, subject to the limitations in Section 1.03.

Section 3.05  Operation and Maintenance of Property.

         (a) Repair and Maintenance. Borrower will, or will cause SL Green
Management Corp. as agent of Borrower ("Agent") pursuant to that certain
Leasing and Management Agreement, dated as of the date hereof, between
Borrower, as owner, and Agent, as agent (the "LMA") to operate and maintain
the Property in good order, repair, and operating condition. Borrower will, or
will cause Agent to, promptly make or cause to be made all necessary repairs,
replacements, additions, and improvements necessary to ensure that the
Property shall not in any material way be diminished or impaired. Borrower
will not cause or allow any of the Property to be misused, wasted, or to
deteriorate in any material respect and Borrower will not abandon the
Property. No new building, structure, or other improvement shall be
constructed on the Land nor shall any material part of the Improvements be
removed, demolished, or structurally or materially altered, without Lender's
prior written consent, which consent shall be deemed automatically granted if
all members of Borrower unanimously consent to the same.

         (b) Replacement of Property. Borrower will, or will cause Agent to,
keep the Property equipped and will replace all worn out or obsolete Property
with new, comparable fixtures or Property as is appropriate in the prudent
operation of the Property. Borrower will not, without Lender's prior written
consent, remove any material or significant item or items constituting a
portion of Property covered by this Instrument unless the same is replaced by
Borrower with a new, comparable article (i) owned by Borrower free and clear
of any lien or security interest (other than the Permitted Encumbrances and
those created by this Instrument) or (ii) leased by Borrower (A) with Lender's
prior written consent (provided, however that no such consent shall be
required if the members of Borrower have unanimously approved the terms of
such lease in writing) or (B) if the replaced Property was leased at the time
of execution of this Instrument.

         (c) Compliance with Laws. The Property shall be maintained, used, and
operated in compliance with all (i) present and future laws, Environmental
Laws (defined below), ordinances, regulations, and requirements (including
zoning and building codes) of any governmental or quasi-governmental authority
or agency applicable to Borrower or the Property (collectively, the "Laws");
(ii) orders, rules, and regulations of any regulatory, licensing, accrediting,
insurance underwriting or rating organization, or other body exercising
similar functions; (iii) duties or obligations of any kind imposed under any
Permitted Encumbrance or by law, covenant, condition, agreement, or easement,
public or private; and (iv) policies of insurance at any time in force with
respect to the Property. If proceedings are initiated or Borrower receives
notice that it or the Property is not in compliance with any of the foregoing,
Borrower will promptly send Lender notice and a copy of the proceeding or
violation notice. If the Property is not in compliance with all Laws, Lender
may impose additional requirements upon Borrower, which may include monetary
reserves or financial equivalents.


         (d) Zoning and Title Matters. Borrower shall not, without Lender's
prior written consent (unless the members of Borrower have unanimously agreed
in writing to do any of the foregoing, in which case, Lender's consent shall
be deemed granted automatically): (i) initiate or support any zoning
reclassification of the Property or variance under existing zoning ordinances;
(ii) modify or supplement any of the Permitted Encumbrances (provided that
Lender will not unreasonably withhold, delay or condition any such
modification or supplement unless the same materially adversely affects the
operation of the Property or Lender's rights hereunder); (iii) impose any
restrictive covenants or encumbrances upon the Property; (iv) execute or file
any subdivision plat affecting the Property; (v) consent to the annexation of
the Property to any municipality; (vi) permit the Property to be used by the
public or any Person in a way that might make a claim of adverse possession or
any implied dedication or easement possible; (vii) cause or permit the
Property to become a non-conforming use under zoning ordinances or any present
or future non-conforming use of the Property to be discontinued; or (viii)
fail to comply with the terms of the Permitted Encumbrances.



Section 3.06  Insurance.

         (a) Casualty Insurance. Borrower shall keep the Property insured for
the benefit of Lender by (i) an "All Risk of Physical Loss" policy or the
broadest form of extended coverage endorsement in an amount sufficient to
prevent Lender from ever becoming a co-insurer under the policy or Laws, but
in no event less than the lesser of (A) the Obligations or (B) the Full
Insurable Value (defined below) of the Property, subject to verification by
Lender, and with a deductible not to exceed Twenty-Five Thousand Dollars
($25,000.00). "Full Insurable Value" shall mean the one hundred percent (100%)
replacement cost of the Property, without allowance for depreciation and
exclusive of the cost of excavations, foundations, and footings, as
determined, at Borrower's expense, periodically (but at least once per year)
by the insurance company or an appraiser, engineer, architect, or contractor
approved by said company and Lender; (ii) rent, business interruption, and/or
use and occupancy insurance in an amount equal to one (1) year's total income
from the Property including all rent, other income, and reimbursement of
operating expenses; (iii) against damage by flood if the Property is located
in an area identified by the Secretary of Housing and Urban Development, or
any successor, as an area having special flood hazards and in which flood
insurance has been made available under the Flood Acts in an amount equal to
the lesser of (A) the original amount of the Note or (B) the maximum limit of
coverage available for the Property under the Flood Acts; (iv) against damage
or loss from (A) sprinkler system leakage and (B) boilers, boiler tanks,
heating and air-conditioning equipment, pressure vessels, auxiliary piping,
and similar apparatus, in the amount required by Lender; (v) during the period
of any construction, repair, restoration, or replacement of the Property, a
standard builder's risk policy with extended coverage in an amount at least
equal to the Full Insurable Value of such Property, and worker's compensation,
in statutory amounts; and (vi) against damage or loss by earthquake and other
natural phenomenon in the amounts reasonably required by Lender.

         (b) Liability and Other Insurance. Borrower shall maintain
comprehensive general liability insurance on an occurrence basis covering
Borrower and Lender, as an additional insured, against claims for bodily
injury or death or property damage occurring in, upon, or about the Property
or any street, drive, sidewalk, curb, or passageway adjacent thereto, in the
amount required by Lender (but in no event less than Ten Million Dollars
($10,000,000.00) combined single limit per occurrence, which may be based on a
combination of primary coverage plus umbrella coverage), which insurance shall
include operations and blanket contractual liability coverage which insures
contractual liability under the indemnifications set forth in Section 8.02
(but such coverage or the amount thereof shall in no way limit such
indemnifications). Upon request, Borrower shall maintain insurance or carry
additional amounts of insurance covering Borrower or the Property as Lender
shall reasonably require including against war risks.

         (c) Form of Policy. All insurance required under this Section shall
be fully paid for, non-assessable, and the policies shall contain such
provisions, endorsements, and expiration dates as Lender shall reasonably
require. The policies shall be issued by insurance companies authorized to do
business in the State of New York, approved by Lender, and having (i) an
investment grade rating or claims paying ability assigned by one or more
credit rating agencies approved by Lender (a "Rating Agency") and (ii) a
general policy rating of A or better and a financial class of VI or better by
A.M. Best Company, Inc. (or if a rating of A.M. Best Company, Inc. is no
longer available, a similar rating from a similar or successor service). In
addition, all policies shall (x)include a standard Lender clause, without
contribution, in the name of Lender and (y) provide that they shall not be
canceled, amended, or materially altered (including reduction in the scope or
limits of coverage) without at least thirty (30) days' prior notice to Lender.

         (d) Original Policies. Borrower shall deliver to Lender (i) original
or certified copies of all policies (and renewals) required under this Section
and (ii) receipts evidencing payment of all premiums on such policies at least
thirty (30) days prior to their expiration. If original and renewal policies
are unavailable or if coverage is under a blanket policy, Borrower shall
deliver duplicate originals, or, if unavailable, original certificates
evidencing that such policies are in full force and effect together with
certified copies of the original policies.

         (e) General Provisions. Borrower shall not carry separate or
additional insurance concurrent in form or contributing in the event of loss
with that required under this Section unless endorsed in favor of Lender as
per this Section and approved by Lender in all respects. In the event of
foreclosure of this Instrument or other transfer of title or assignment of the
Property in extinguishment, in whole or in part, of the Obligations, all
right, title, and interest of Borrower in and to all policies of insurance
then in force regarding the Property and all proceeds payable thereunder and
unearned premiums thereon shall immediately vest in the purchaser or other
transferee of the Property. No approval by Lender of any insurer shall be
construed to be a representation, certification, or warranty of its solvency.
No approval by Lender as to the amount, type, or form of any insurance shall
be construed to be a representation, certification, or warranty of its
sufficiency. Borrower shall comply with all insurance requirements and shall
not cause or permit any condition to exist which would be prohibited by an
insurance requirement or would invalidate the insurance coverage on the
Property.

         (f)  Insurance  Approval.  Notwithstanding  anything  contained  in
this  Section  3.06 to the  contrary, Lender approves of the insurance
provided by Borrower as described in the certificate  annexed hereto and made
a part hereof as Exhibit G.

Section 3.07  Damage and Destruction of Property.

         (a) Borrower's Obligations. If any damage to, loss, or destruction of
the Property occurs (any "Damage"), (i) Borrower shall promptly notify Lender
and take all necessary steps to preserve any undamaged part of the Property
and (ii) if the insurance proceeds are made available for Restoration (defined
below) (but regardless of whether any proceeds are sufficient for
Restoration), Borrower shall promptly commence and diligently pursue to
completion the restoration, replacement, and rebuilding of the Property as
nearly as possible to its value and condition immediately prior to the Damage
or a Taking (defined below) in accordance with plans and specifications
approved by Lender in its reasonable discretion ("Restoration"). Borrower
shall comply with other reasonable requirements established by Lender to
preserve the security under this Instrument.

         (b) Lender's Rights. If any Damage occurs and some or all of it is
covered by insurance, then (i) Lender may, but is not obligated to, make proof
of loss if not made promptly by Borrower and Lender is authorized and
empowered by Borrower to settle, adjust, or compromise any claims for the
Damage (and Borrower hereby irrevocably appoints and constitutes Lender as
Borrower's attorney-in-fact coupled with an interest and with full power of
substitution for such purpose, provided that, Lender shall not exercise its
rights under such power of attorney unless an Event of Default shall have
occurred); (ii) each insurance company concerned is authorized and directed to
make payment directly to Lender for the Damage; and (iii) Lender may apply the
insurance proceeds in any order it determines (A) to reimburse Lender for all
Costs (defined below) related to collection of the proceeds and (B) subject to
Section 3.07(c) and at Lender's option, to (1) payment of all or part of the
Obligations, whether or not then due and payable, in the order determined by
Lender (provided that if any Obligations remains outstanding after this
payment, the unpaid Obligations shall continue in full force and effect and
Borrower shall not be excused in the payment thereof); (2) the cure of any
default under the Documents; or (3) the Restoration. Any insurance proceeds
held by Lender shall be held, to the extent easily accomplishable by Lender,
in an interest bearing account in a financial institution reasonably
acceptable to Lender with all interest thereon to be deemed part of the
insurance proceeds and applied in accordance with this Section 3.07. If
Borrower receives any insurance proceeds for the Damage, Borrower shall
promptly deliver the proceeds to Lender. Notwithstanding anything in this
Instrument or at law or in equity to the contrary, none of the insurance
proceeds paid to Lender shall be deemed trust funds and Lender may dispose of
these proceeds as provided in this Section. Borrower expressly assumes all
risk of loss from any Damage, whether or not insurable or insured against.

         (c) Application of Proceeds to Restoration. Notwithstanding anything
contained herein to the contrary, Lender shall make the Net Proceeds (defined
below) available to Borrower for Restoration if: (i) there shall then be no
Event of Default; (ii) Lender shall be satisfied in the exercise of its
reasonable judgment that (A) Restoration can and will be substantially
completed within one (1) year after the Damage occurs and at least six (6)
months prior to the maturity of the Note, and (B) Leases that are terminated
or terminable as a result of the Damage cover an aggregate of less than fifty
(50%) of the total rentable square footage contained in the Property or such
Tenants agree in writing to continue their Leases; (iii) Borrower shall have
entered into a general construction contract reasonably acceptable to Lender
for Restoration (which contract shall automatically be deemed acceptable if
the contract has been unanimously approved by the members of Borrower in
writing); and (iv) in Lender's reasonable judgment, after Restoration has been
completed the net cash flow of the Property will be sufficient to cover the
operating expenses of the Property, including payments due and reserves
required under the Documents. Notwithstanding any provision of this Instrument
to the contrary, Lender shall not be obligated to make any portion of the Net
Proceeds available for Restoration unless, at the time of the disbursement
request, Lender has determined, in its reasonable discretion, that (y)
Restoration can be completed at a cost that does not exceed the aggregate of
the remaining Net Proceeds and any funds deposited with Lender by Borrower
("Additional Funds") (provided that the failure of Lender or any Affiliate of
Lender, acting in its capacity as a member of Borrower only, to provide funds
to Borrower for such deposit pursuant to the terms of Borrower's operating
agreement shall not under any circumstances result in Lender's determination
that there are not sufficient Additional Funds) and (z) the aggregate of any
loss of rental income insurance proceeds that the carrier has acknowledged to
be payable ("Rent Loss Proceeds"), the sums payable by tenants pursuant to
their respective Leases, and any funds deposited with Lender by Borrower are
sufficient to cover all costs and operating expenses of the Property,
including payments due and reserves required under the Documents.

         (d) Disbursement of Proceeds. If Lender elects or is required to make
insurance proceeds available for Restoration, Lender shall, through a
disbursement procedure reasonably established by Lender, periodically make
available to Borrower in installments the net amount of all insurance proceeds
received by Lender after deduction of all reasonable costs and expenses
incurred by Lender in connection with the collection and disbursement of such
proceeds ("Net Proceeds") and, if any, the Additional Funds. The amounts
periodically disbursed to Borrower shall be based upon the amounts currently
due under the construction contract for Restoration and if requested by
Lender, Lender's receipt of (i) appropriate lien waivers, (ii) a certification
of the percentage of Restoration completed by an architect or engineer
acceptable to Lender, and (iii) title insurance protection against
materialmen's and mechanic's liens. At Lender's election, the disbursement of
funds may be handled by a disbursing agent selected by Lender, and such
agent's reasonable fees and expenses shall be paid by Borrower. The Net
Proceeds, Rent Loss Proceeds, and any Additional Funds shall constitute
additional security for the Loan and Borrower shall execute, deliver, file
and/or record, at its expense, such instruments as Lender requires to grant to
Lender a perfected, first-priority security interest in these funds. If the
Net Proceeds are made available for Restoration and (A) Borrower refuses or
fails to complete the Restoration, (B) an Event of Default occurs, or (C) the
Net Proceeds or Additional Funds are not applied to Restoration, then any
undisbursed portion may, at Lender's option, be applied to the Obligations in
any order of priority Lender deems appropriate.

         (e) Real Property Law Section 254. The provisions of subsection 4 of
Section 254 of the Real Property Law of New York covering the insurance of
buildings against loss by fire that are inconsistent with the provisions of
this Mortgage shall not apply to the terms of this Mortgage. Nothing contained
herein, except for the immediately preceding sentence, shall be construed as
depriving Lender of any right or advantage available under Section 254 of the
Real Property Law of the State of New York, and all covenants herein that
differ therefrom shall be construed as conferring additional and not
substitute rights and advantages.

Section 3.08  Condemnation.

         (a) Borrower's Obligations. Borrower will promptly notify Lender of
any threatened or instituted proceedings for the condemnation or taking by
eminent domain of the Property including any change in any street, whether as
to grade, access, or otherwise (a "Taking"). Borrower shall, at its expense,
(i) diligently prosecute these proceedings, (ii) deliver to Lender copies of
all papers served in connection therewith, and (iii) consult and cooperate
with Lender in the handling of these proceedings. No settlement of these
proceedings shall be made by Borrower without Lender's prior written consent.
Lender may participate in these proceedings (but shall not be obligated to do
so) and Borrower will sign and deliver all instruments requested by Lender to
permit this participation.

         (b) Lender's Rights to Proceeds. All condemnation awards, judgments,
decrees, or proceeds of sale in lieu of condemnation ("Award") are assigned
and shall be paid to Lender. Borrower authorizes Lender to collect and receive
them, to give receipts for them, to accept them in the amount received without
question or appeal, and/or to appeal any judgment, decree, or award. Borrower
will sign and deliver all instruments requested by Lender to permit these
actions.

         (c) Application of Award. Lender shall have the right to hold and
apply any Award, subject to Section 3.08(d), as per Section 3.07 for insurance
proceeds held by Lender. If Borrower receives any Award, Borrower shall
promptly deliver them to Lender. Notwithstanding anything in this Instrument
or at law or in equity to the contrary, none of the Award paid to Lender shall
be deemed trust funds and Lender may dispose of these proceeds as provided in
this Section.

         (d) Application of Award to Restoration. With respect to any portion
of the Award that is not for loss of value or property, Lender shall permit
the application of the Award to Restoration in accordance with and subject to
the provisions of Section 3.07 if: (i) no more than (A) twenty (20%) of the
gross area of the Improvements is affected by the Taking, (ii) the amount of
the loss does not exceed twenty percent (20%) of the original amount of the
Note; (iii) the Taking does not bar access to the Property from all public
rights-of-way; (iv) there is no Event of Default at the time of application.
Any portion of the Award that is (1) for loss of value or property or (2) in
excess of the cost of any Restoration permitted above, may, in Lender's sole
discretion, be applied against the Obligations or paid to Borrower.

         (e) Effect on the Obligations. Notwithstanding any Taking, Borrower
shall continue to pay and perform the Obligations as provided in the
Documents. Any reduction in the Obligations due to application of the Award
shall take effect only upon Lender's actual receipt and application of the
Award to the Obligations. If the Property shall have been foreclosed, sold
pursuant to any power of sale granted hereunder, or transferred by
deed-in-lieu of foreclosure prior to Lender's actual receipt of the Award,
Lender may apply the Award received to the extent of any deficiency upon such
sale and Costs incurred by Lender in connection with such sale.

Section 3.09 Lien and Liabilities. (a) Borrower shall pay, bond, or otherwise
discharge all claims and demands of mechanics, materialman, laborers, and
others which, if unpaid, might result in a lien or encumbrance on the Property
or the Rents (collectively, "Liens") and Borrower shall, at its sole expense,
do everything necessary to preserve the lien and security interest created by
this Instrument and its priority; subject to Borrower's right to contest any
such claims or demands subject to and in accordance with the provisions of
Subsection (b) of this Section 3.09. Nothing in the Documents shall be deemed
or construed as constituting the consent or request by Lender, express or
implied, to any contractor, subcontractor, laborer, mechanic or materialman
for the performance of any labor or the furnishing of any material for any
improvement, construction, alteration, or repair of the Property. Borrower
further agrees that Lender does not stand in any fiduciary relationship to
Borrower. Any contributions made, directly or indirectly, to Borrower by or on
behalf of any of its members (other than Lender in its capacity as Lender),
shall be treated as equity and shall be subordinate and inferior to the rights
of Lender under the Documents.

         (b) Right to Contest. So long as no Event of Default is continuing,
Borrower may, prior to delinquency and at its sole expense, contest any claim
or demand made by any mechanic, materialman or laborer, but this shall not
change or extend Borrower's obligation to pay or satisfy such claim or demand
as required above unless (i) Borrower gives Lender prior written notice of its
intent to contest the claim or demand; (ii) Borrower demonstrates to Lender's
reasonable satisfaction that (1) the Property will not be sold to satisfy the
claim or demand prior to the final determination of the legal proceedings, (2)
it has furnished a bond or surety (reasonably satisfactory to Lender in form
and amount) sufficient to prevent the imposition of any lien or a sale of the
Property; (iii) at Lender's option, Borrower has deposited the full amount
necessary to pay any unpaid portion of the claim with Lender (provided that
Lender shall not require such a deposit if Lender or its Affiliate, in its
capacity as a member of Borrower only, has consented in writing to such
contest); and (iv) such proceeding shall be permitted under any other
instrument to which Borrower or the Property is subject (whether superior or
inferior to this Instrument).

Section 3.10 Tax and Insurance Deposits. At Lender's option following the
occurrence of an Event of Default, Borrower shall make monthly deposits
("Deposits") with Lender equal to one-twelfth (1/12) of the annual Assessments
(except for income taxes, franchise taxes, ground rents, maintenance charges
and utility charges) and the premiums for insurance required under Section
3.06 (the "Insurance Premiums") together with amounts sufficient to pay these
items thirty (30) days before they are due (collectively, the " Impositions").
Lender shall, in its reasonable discretion, estimate the amount of the
Deposits until ascertainable. At that time, Borrower shall promptly deposit
any deficiency. Borrower shall promptly notify Lender of any changes to the
amounts, schedules and instructions for payment of the Impositions. Borrower
authorizes Lender or its agent to obtain the bills for Assessments directly
from the appropriate tax or governmental authority. All Deposits are pledged
to Lender and shall constitute additional security for the Obligations. The
Deposits shall be held by Lender without interest (except to the extent
required under Laws) and may be commingled with other funds. If (a) there is
no Event of Default at the time of payment, (b) Borrower has delivered bills
or invoices to Lender for the Impositions in sufficient time to pay them when
due, (c) the Deposits are sufficient to pay the Impositions or Borrower has
deposited the necessary additional amount, then Lender shall pay the
Impositions prior to their due date. Any Deposits remaining after payment of
the Impositions shall, at Lender's option, be credited against the Deposits
required for the following year or paid to Borrower. If an Event of Default
occurs, the Deposits may, at Lender's option, be applied to the Obligations in
any order of priority. Borrower shall not claim any credit against the
principal and interest due under the Note for the Deposits. Upon an assignment
or other transfer of this Instrument, Lender may pay over the Deposits in its
possession to the assignee or transferee and then it shall be completely
released from all liability with respect to the Deposits. Borrower shall look
solely to the assignee or transferee with respect thereto. This provision
shall apply to every transfer of the Deposits to a new assignee or transferee.
Subject to Article V, a transfer of title to the Land shall automatically
transfer to the new owner the beneficial interest in the Deposits. Upon full
payment and satisfaction of this Instrument or, at Lender's option, at any
prior time, the balance of the Deposits in Lender's possession shall be paid
over to the record owner of the Land and no other party shall have any right
or claim to the Deposits. Lender may transfer all its duties under this
Section to such servicer or financial institution as Lender may periodically
designate and Borrower agrees to make the Deposits to such servicer or
institution.

Section 3.11 ERISA. Borrower represents and warrants to Lender that (a)
Borrower has not, or during the immediately preceding year has not exercised,
the authority to appoint or terminate The Prudential Insurance Company of
America ("Prudential") as investment manager of any assets of the employee
benefit plans whose assets are invested in the separate account (the
"Account") that is the source of funds used by Lender to make the Loan, or to
negotiate the terms of any management agreement between Prudential and such
plan in connection with its investments in the Account; and (b) Borrower
qualifies as an "operating company" or a "real estate operating company"
within the meaning of 29 C.F.R. Section 2510.3-101(c). Borrower shall deliver
to Lender such certifications and/or other evidence periodically requested by
Lender, in its sole discretion, to verify these representations and
warranties. Failure to deliver these certifications or evidence, breach of
these representations and warranties, or consummation of any transaction which
would cause this Instrument or any exercise of Lender's rights under this
Instrument to (i) constitute a non-exempt prohibited transaction under ERISA
or (ii) violate ERISA or any state statute regulating governmental plans
(collectively, a "Violation"), shall be an Event of Default. Notwithstanding
anything in the Documents to the contrary, no sale, assignment, or transfer of
any direct or indirect right, title, or interest in Borrower or the Property
(including creation of a junior lien, encumbrance or leasehold interest) shall
be permitted that would, in Lender's opinion, negate Borrower's
representations in this Section or cause a Violation. At least fifteen (15)
days before consummation of any of the foregoing, Borrower shall obtain from
the proposed transferee or lienholder (A) a certification to Lender that the
representations and warranties of this Section will be true after consummation
and (B) an agreement to comply with this Section.

Section 3.12  Environmental Representations, Warranties and Covenants.

         (a) Environmental Representations and Warranties. Borrower represents
and warrants, to Borrower's actual knowledge, exclusive of any knowledge of

other government directives or requirements, as well as common law, that apply
to Borrower or the Property and relate to Hazardous Materials including the
Comprehensive Environmental Response, Compensation and Liability Act and the
Resource Conservation and Recovery Act. "Hazardous Materials" shall mean
petroleum and petroleum products and compounds containing them, including
gasoline, diesel fuel and oil; explosives, flammable materials; radioactive
materials; polychlorinated biphenyls ("PCBs") and compounds containing them;
lead and lead-based paint; asbestos or asbestos-containing materials in any
form that is or could become friable; underground or above-ground storage

of which on the Property is prohibited by any federal, state or local
authority; any substance that requires special handling; and any other

all use and operation of the Property shall be in compliance with all
Environmental Laws and required permits; (ii) there shall be no Releases of
Hazardous Materials affecting the Property; (iii) there shall be no Hazardous

expense, fully and expeditiously cooperate in all activities in Section
3.12(c) including providing all relevant information and making knowledgeable
persons available for interviews; (vi) Borrower shall, at its sole expense,
(A) perform any environmental site assessment or other investigation of
environmental conditions at the Property upon Lender's request based on
Lender' s reasonable belief that the Property is not in compliance with all
Environmental Laws, (B) share with Lender the results and reports and Lender
and the Indemnified Parties (defined below) shall be entitled to rely on such
results and reports, and (C) complete any remediation of Hazardous Materials
affecting the Property or other actions required by any Environmental Laws;
(vii) Borrower shall not allow any Tenant or other user of the Property to
violate any Environmental Law; and (viii) Borrower shall immediately notify
Lender in writing after it becomes aware of (A) the presence, Release, or

non-compliance of the Property with any Environmental Laws, (C) any actual or
potential Environmental Lien, (D) any required or proposed remediation of
environmental conditions relating to the Property, and (E) any written
communication or notice from any person relating to Hazardous Materials.

         (c) Lender's Rights. Lender and any Person designated by Lender may
enter the Property at reasonable times upon reasonable advance notice to
assess the environmental condition of the Property and its use including (i)
conducting any environmental assessment or audit (the scope of which shall be
determined by Lender) and (ii) taking samples of soil, groundwater or other
water, air, or building materials, and conducting other invasive testing at
all reasonable times when (A) an Event of Default has occurred under the
Documents, (B) Lender reasonably believes that a Release has occurred or the
Property is not in substantial compliance with all Environmental Laws, or (C)
the Loan is being considered for sale. Borrower shall cooperate with and
provide access to Lender and such Person, and Lender shall use reasonable
efforts to minimize interference with Tenants under their respective Leases.

Section 3.13 Electronic Payments. All payments due under the Documents shall
be made by electronic funds transfer from a bank account established and
maintained by Borrower for this purpose with a depository reasonably
satisfactory to Lender. Borrower shall direct the depository to transmit such
payments on or before their respective due dates to an account designated in
writing by Lender. Lender shall have the right to require Borrower to select a
different depository after thirty (30) days' prior notice. All costs of (a)
establishing and maintaining such account and (b) the electronic funds
transfers shall be paid by Borrower.

Section 3.14 Inspection. Subject to the provisions of Section 3.12(c) with
respect to environmental conditions, Borrower shall allow Lender and any
Person designated by Lender to enter upon the Property and conduct tests or
inspect the Property at all reasonable times upon reasonable notice; provided
that, Lender shall use all reasonable efforts to minimize interference with
Tenants under their respective Leases. Borrower shall assist Lender and such
Person in effecting such inspection.

Section 3.15  Records, Reports, and Audits.

         (a) Records and Reports. Borrower shall maintain such records and
reports as shall be required pursuant to Borrower's operating agreement.

         (b) Inspection of Records. Borrower shall allow Lender or any Person
designated by Lender to examine, audit, and make copies of all such books and
records and all supporting data at the place where these items are located at
all reasonable times after reasonable advance notice.

Section 3.16 Borrower's Certificates. Within ten (10) days after Lender's
request, Borrower shall furnish a written certification to Lender as to (a)
the amount of the Obligations outstanding; (b) the interest rate, terms of
payment, and maturity date of the Note; (c) the date to which payments have
been paid under the Note; (d) whether any offsets or defenses exist against
the Obligations and a detailed description of any listed; (e) whether there
are any events that with the passage of time and/or notice would constitute a
default on Lender's part or to the knowledge of Borrower on Borrower's part
under the Documents and a detailed description of any listed; (f) whether the
Documents are in full force and effect; and (g) any other matters reasonably
requested by Lender related to the Leases, the Obligations, the Property, or
the Documents. Promptly upon Lender's request, Borrower shall use reasonable
efforts to deliver a written certification to Lender from Tenants specified by
Lender that: (a) their Leases are in full force and effect; (b) there are no
defaults (or events which with the passage of time and/or notice would
constitute a default) under their Leases or a detailed description of any
listed; (c) none of the Rents have been paid more than one month in advance;

substantially different than as is required by such Tenant's Lease.

Section 3.17 Full Performance Required, Survival of Warranties. All
representations and warranties of Borrower made in any Documents in connection
with the Loan shall survive the execution and delivery of the Documents and
shall remain continuing warranties, and representations of Borrower until the
Loan is repaid in full.

Section 3.18 Additional Security. No other security now existing or taken
later to secure the Obligations shall be affected by the execution of the
Documents and all additional security shall be held as cumulative. The taking
of additional security, execution of partial releases, or extension of the
time of payment obligations of Borrower shall not diminish the effect and lien
of this Instrument and shall not affect the liability or obligations of any
maker or guarantor. Neither the acceptance of the Documents nor their
enforcement shall prejudice or affect Lender's right to realize upon or
enforce any other security now or later held by Lender. Lender may enforce the
Documents or any other security in such order and manner as it may determine
in its discretion.

Section 3.19 Further Acts. Borrower shall take all necessary actions to (a)
keep valid and effective the lien and rights of Lender under the Documents and
(b) protect the lawful owner of the Documents. Promptly upon request by Lender
and at Borrower's expense, Borrower shall execute additional instruments and
take such actions as Lender reasonably believes are necessary or desirable to
(i) maintain or grant Lender a first-priority, perfected lien on the Property,
(ii) correct any error or omission in the Documents, and (iii) effect the
intent of the Documents, including filing/recording the Documents, additional
mortgages, financing statements, and other instruments.

            ARTICLE IV - ADDITIONAL ADVANCES; EXPENSES; SUBROGATION

expenses, and disbursements actually incurred by Borrower or Lender in
connection with the granting, closing, servicing, and enforcement of (a) the
Loan and Documents or (b) attributable to Borrower as owner of the Property.
The term "Costs" shall mean any of the foregoing incurred in connection with
(a) any default by Borrower under the Documents, (b) the servicing of the
Loan, or (c) the enforcement following the occurrence of an event that with
the giving of notice or passage of time or both would constitute an Event of
Default, reasonable exercise, compromise, defense, litigation, or settlement
of any of Lender's rights or remedies under the Documents or relating to the
Loan or the Obligations.

Section 4.02 Subrogation. If any proceeds of the Note were used to extinguish,
extend or renew any indebtedness on the Property, then, to the extent of the
funds so used and the fullest extent permitted under applicable law, (a)
Lender shall be subrogated to all rights, claims, liens, titles and interests
existing on the Property held by the holder of such indebtedness and (b) these
rights, claims, liens, titles and interests are not waived but rather shall
(i) continue in full force and effect in favor of Lender and (ii) are merged
with the lien and security interest created by the Documents as cumulative
security for the payment and performance of the Obligations.

          ARTICLE V - SALE, TRANSFER, OR ENCUMBRANCE OF THE PROPERTY

Section 5.01 Due-on-Sale or Encumbrance. It shall be an Event of Default and,
at the sole option of Lender, Lender may accelerate the Obligations and the

reason), (a) shall sell, convey, assign, transfer, dispose of or be divested

way, whether voluntary or involuntary, except in a manner in strict compliance
with the terms of Borrower's operating agreement, or (b) in the event of the
transfer, pledge, voluntary or involuntary sale, or encumbrance (or any of the
foregoing at one time or over any period of time) of all or any interest in
Borrower or any member of Borrower (other than an Affiliate of Lender), except
in a manner in strict compliance with the terms of Borrower's operating
agreement.

Section 6.01  Events of Default.  The following shall be an "Event of Default":

         (a) if Borrower fails to make any payment required under the
Documents when due and such failure continues for five (5) days after written

any notice of monetary default during that twelve (12) month period;

         (b) except for defaults listed in the other subsections of this

days (the "Grace Period"); provided, however, that the Grace Period shall be
extended up to an additional one hundred twenty (120) days (for a total of one

by Lender in good faith that same can be cured within one hundred fifty (150)
days after the default, (B) no lien or security interest created by the

(C) Lender's immediate exercise of any remedies provided hereunder or by law
is not necessary for the protection or preservation of the Property or
Lender's security interest;

         (c) if any default under Article V occurs and the event giving rise
to such default is not voided or rescinded to Lender's reasonable satisfaction
within five (5) days after written notice of the same;

any court of competent jurisdiction or shall be consented to by Borrower; or

         (k) (i) the consummation by Borrower of any transaction that would
cause (A) the Loan or any exercise of Lender's rights under the Documents to
constitute a non-exempt prohibited transaction under ERISA or (B) a violation
of a state statute regulating governmental plans; (ii) the failure of any
representation in Section 3.11 to be true and correct in all respects; or
(iii) the failure of Borrower to provide Lender with the written
certifications required by Section 3.11.

Section 6.02 Remedies. If an Event of Default occurs, Lender or any person
designated by Lender may (but shall not be obligated to) take any action

accept by assignment, pledge, or otherwise any other property in place thereof
as Lender may require without being accountable for so doing to any other
lienholder;

         (i) apply any Deposits to the following items in any order and in

constitute commercially reasonable notice to Borrower; or

         (k) take any other action permitted under any Laws.

Borrower hereby consents to, ratifies, and confirms the exercise by Lender of
its rights under this Instrument and appoints Lender as its attorney-in-fact,
which appointment shall be deemed to be coupled with an interest and
irrevocable, for such purposes.

Section 6.03 Expenses. All Costs, expenses, or other amounts paid or incurred

Obligations, (b) secured by this Instrument, and (c) allowed and included as
part of the Obligations in any foreclosure, decree for sale, power of sale, or
other judgment or decree enforcing Lender's rights under the Documents.

Section 6.04 Rights Pertaining to Sales. To the extent permitted under (and in
accordance with) any Laws, the following provisions shall, as Lender may
determine in its sole discretion, apply to any sales of the Property under
Article VI, whether by judicial proceeding, judgment, decree, power of sale,
foreclosure or otherwise: (a) Lender may conduct multiple sales of any part of
the Property in separate tracts or in its entirety and Borrower waives any
right to require otherwise; (b) any sale may be postponed or adjourned by
public announcement at the time and place appointed for such sale or for such
postponed or adjourned sale without further notice; and (c) Lender may acquire
the Property and, in lieu of paying cash, may pay by crediting against the
Obligations the amount of its bid, after deducting therefrom any sums which
Lender is authorized to deduct under the provisions of the Documents.

Section 6.05 Applications of Proceeds. Any proceeds received from any sale or
disposition under Article VI or otherwise, together with any other sums held
by Lender, shall, except as expressly provided to the contrary, be applied in
the order determined by Lender to: (a) payment of all actual and reasonable
Costs and expenses of any enforcement action or foreclosure sale, including
interest thereon at the applicable interest rate specified in the Note, which
shall be the Default Rate unless prohibited by Laws; (b) all taxes,
Assessments, and other charges then due and payable unless the Property was
sold subject to these items; (c) payment of the Obligations in such order as
Lender may elect; (d) payment of any other sums secured or required to be paid
by Borrower; and (e) payment of the surplus, if any, to any person lawfully
entitled to receive it. Borrower and Lender intend and agree that during any
period of time between any foreclosure judgment that may be obtained and the
actual foreclosure sale that the foreclosure judgment will not extinguish the
Documents or any rights contained therein including the obligation of Borrower
to pay all Costs and to pay interest at the applicable interest rate specified
in the Note, which shall be the Default Rate unless prohibited by Laws.

Section 6.06 Additional Provisions as to Remedies. No failure, refusal,
waiver, or delay by Lender to exercise any rights under the Documents upon any
default or Event of Default shall impair Lender's rights or be construed as a
waiver of, or acquiescence to, such or any subsequent default or Event of
Default. No recovery of any judgment by Lender and no levy of an execution
upon the Property or any other property of Borrower shall affect the lien and
security interest created by this Instrument and such liens, rights, powers,
and remedies shall continue unimpaired as before. Lender may resort to any
security given by this Instrument or any other security now given or hereafter
existing to secure the Obligations, in whole or in part, in such portions and
in such order as Lender may deem advisable, and no such action shall be
construed as a waiver of any of the liens, rights, or benefits granted
hereunder. Acceptance of any payment after any Event of Default shall not be
deemed a waiver or a cure of such Event of Default and such acceptance shall
be deemed an acceptance on account only. If Lender has started enforcement of
any right by foreclosure, sale, entry, or otherwise and such proceeding shall
be discontinued, abandoned, or determined adversely for any reason, then
Borrower and Lender shall be restored to their former positions and rights
under the Documents with respect to the Property, subject to the lien and
security interest hereof.

Section 6.07 Waiver of Rights and Defenses. To the fullest extent Borrower may
do so under Laws, Borrower (a) will not at any time insist on, plead, claim,
or take the benefit of any statute or rule of law now or later enacted
providing for any appraisement, valuation, stay, extension, moratorium,
redemption, or any statute of limitations; (b) for itself, its successors and
assigns, and for any person ever claiming an interest in the Property (other
than Lender), waives and releases all rights of redemption, reinstatement,
valuation, appraisement, notice of intention to mature or declare due the
whole of the Obligations, all rights to a marshaling of the assets of
Borrower, including the Property, or to a sale in inverse order of alienation,
in the event of foreclosure of the liens and security interests created under
the Documents; (c) shall not be relieved of its obligation to pay the
Obligations as required in the Documents nor shall the lien or priority of the
Documents be impaired by any agreement renewing, extending, or modifying the
time of payment or the provisions of the Documents (including a modification
of any interest rate), unless expressly released, discharged, or modified by
such agreement. Regardless of consideration and without any notice to or
consent by the holder of any subordinate lien, security interest, encumbrance,
right, title, or interest in or to the Property, Lender may (a) release any
person liable for payment of the Obligations or any portion thereof or any
part of the security held for the Obligations or (b) modify any of the
provisions of the Documents without impairing or affecting the Documents or
the lien, security interest, or the priority of the modified Documents as
security for the Obligations over any such subordinate lien, security
interest, encumbrance, right, title, or interest.

                       ARTICLE VII - SECURITY AGREEMENT

Section 7.01 Security Agreement. This Instrument constitutes both a real
property mortgage and a "security agreement" within the meaning of the U.C.C.
The Property includes real and personal property and all tangible and
intangible rights and interest of Borrower in the Property. Borrower grants to
Lender, as security for the Obligations, a security interest in the Personal
Property to the fullest extent that the same may be subject to the U.C.C.
Borrower authorizes Lender to file any financing or continuation statements
and amendments thereto relating to the Personal Property without the signature
of Borrower if permitted by Laws.

        ARTICLE VIII - LIMITATION ON PERSONAL LIABILITY AND INDEMNITIES

Section 8.01 Limited Recourse Liability. The provisions of Paragraph 8 and
Paragraph 9 of the Note are incorporated into this Instrument as if such
provisions were set forth in their entirety in this Instrument.

Section 8.02 General Indemnity. Borrower agrees that while Lender has no
liability to any person in tort or otherwise as lender and that Lender is not
directly an owner or operator of the Property, Borrower shall, at its sole
expense, protect, defend, release, indemnify and hold harmless ("indemnify")
the Indemnified Parties (defined below) from any Losses (defined below)
imposed on, incurred by, or asserted against the Indemnified Parties, directly
or indirectly, arising out of or in connection with the Property, Loan, or
Documents, including Losses; provided, however, that the foregoing indemnities
shall not apply to any Losses caused by the gross negligence or willful
misconduct of the Indemnified Parties or caused by any Affiliate of Lender in
its capacity as member of Borrower. The term "Losses" shall mean any claims,
suits, liabilities (including strict liabilities), actions, proceedings,
obligations, debts, damages, losses, Costs, expenses, fines, penalties,
charges, fees, judgments, awards, and amounts paid in settlement of whatever
kind including attorneys' fees (both in-house staff and retained attorneys)
and all other costs of defense. The term "Indemnified Parties" shall mean (a)
Lender, (b) any prior owner or holder of the Note, (c) any existing or prior
servicer of the Loan, (d) the officers, directors, shareholders, partners,
employees and trustees of any of the foregoing, and (e) the heirs, legal
representatives, successors and assigns of each of the foregoing but shall
exclude any Affiliate of Lender in its capacity as member of Borrower.

Section 8.03 Transaction Taxes Indemnity. Borrower shall, at its sole expense,
indemnify the Indemnified Parties from all Losses imposed upon, incurred by,
or asserted against the Indemnified Parties or the Documents relating to
Transaction Taxes.

Section 8.04 Duty to Defend, Costs and Expenses. Upon request, whether
Borrower's obligation to indemnify Lender arises under Article VIII or in the
Documents, Borrower shall defend the Indemnified Parties (in Borrower's or the
Indemnified Parties name) by attorneys and other professionals approved by the
Indemnified Parties. Notwithstanding the foregoing, the Indemnified Parties
may, in their sole discretion, engage their own attorneys and professionals to
defend or assist them and, at their option, their attorneys shall control the
resolution of any claims or proceedings. Upon demand, Borrower shall pay or,
in the sole discretion of the Indemnified Parties, reimburse and/or indemnify
the Indemnified Parties for all Costs imposed on, incurred by, or asserted
against the Indemnified Parties by reason of any items set forth in this
Article VIII and/or the enforcement or preservation of the Indemnified
Parties' rights under the Documents. Any amount payable to the Indemnified
Parties under this Section shall (a) be deemed a demand obligation, (b) be
part of the Obligations, (c) bear interest at the applicable interest rate
specified in the Note, which shall be the Default Rate unless prohibited by
Laws, until paid if not paid on demand, and (d) be secured by this Instrument.

Section 8.05 Recourse Obligation and Survival. Notwithstanding anything to the
contrary in the Documents and in addition to the recourse obligations in the
Note, if any, the obligations of Borrower under Sections 8.03 and 8.04 shall
be a full recourse obligation of Borrower, shall not be subject to any
limitation on personal liability in the Documents, and shall survive (a)
repayment of the Obligations, (b) any termination, satisfaction, assignment or
foreclosure of this Instrument, (c) the acceptance by Lender (or any nominee)
of a deed in lieu of foreclosure, (d) a plan of reorganization filed under the
Bankruptcy Code, or (e) the exercise by the Lender of any rights in the
Documents. Borrower's obligations under Article VIII shall not be affected by
the absence or unavailability of insurance covering the same or by the failure
or refusal by any insurance carrier to perform any obligation under any
applicable insurance policy.

                      ARTICLE IX - ADDITIONAL PROVISIONS

Section 9.01 Usury Savings Clause. All agreements in the Documents are
expressly limited so that in no event whatsoever shall the amount paid or
agreed to be paid under the Documents for the use, forbearance, or detention
of money exceed the highest lawful rate permitted by Laws. If, at the time of
performance, fulfillment of any provision of the Documents shall involve
transcending the limit of validity prescribed by Laws, then, ipso facto, the
obligation to be fulfilled shall be reduced to the limit of such validity. If
Lender shall ever receive as interest an amount which would exceed the highest
lawful rate, the receipt of such excess shall be deemed a mistake and (a)
shall be canceled automatically or (b) if paid, such excess shall be (i)
credited against the principal amount of the Obligations to the extent
permitted by Laws or (ii) rebated to Borrower if it cannot be so credited
under Laws. Furthermore, all sums paid or agreed to be paid under the
Documents for the use, forbearance, or detention of money shall to the extent
permitted by Laws be amortized, prorated, allocated, and spread throughout the
full stated term of the Note until payment in full so that the rate or amount
of interest on account of the Obligations does not exceed the maximum lawful
rate of interest from time to time in effect and applicable to the Obligations
for so long as the Obligations are outstanding.

Section 9.02  Notices.


          (a) In Writing; Address. All notices, requests, approvals,
elections, offers, acceptances, demands, consents, reports and other

hereunder shall be governed by and construed in accordance with the laws of
the State of New York, without regard to principles of conflicts laws. All

shall apply for all purposes of this Instrument unless the context otherwise

Section 9.06 Miscellaneous. If any provision of the Documents shall be held to
be invalid, illegal, or unenforceable in any respect, this shall not affect
any other provisions of the Documents and such provision shall be limited and
construed as if it were not in the Documents. If title to the Property becomes
vested in any person other than Borrower, Lender may, without notice to
Borrower, deal with such person regarding the Documents or the Obligations in
the same manner as with Borrower without in any way vitiating or discharging
Borrower's liability under the Documents or being deemed to have consented to
the vesting. If both the Lender and Borrower's interests ever becomes vested
in any one Person, this Instrument and the lien and security interest created
hereby shall not be destroyed or terminated by the application of the doctrine
of merger and Lender shall continue to have and enjoy all its rights and
privileges as to each separate estate. Upon foreclosure of this Instrument,
none of the Leases shall be destroyed or terminated as a result of such
foreclosure, by application of the doctrine of merger or as a matter of law,
unless Lender takes all actions required by law to terminate the Leases as a
result of foreclosure. All of Borrower's covenants and agreements under the
Documents shall run with the land and time is of the essence. Borrower
appoints Lender as its attorney-in-fact, which appointment is irrevocable and
shall be deemed to be coupled with an interest, with respect to the execution,
acknowledgment, delivery, filing or recording for and in the name of Borrower
of any of the Documents or any documents to be executed by Borrower as
referenced herein. The Documents cannot be amended, terminated, or discharged
except in a writing signed by the party against whom enforcement is sought. No
waiver, release, or other forbearance by Lender will be effective unless it is
in a writing signed by Lender and then only to the extent expressly stated.
The provisions of the Documents shall be binding upon Borrower and its heirs,
devisees, representatives, successors, and assigns including successors in
interest to the Property and inure to the benefit of Lender and its heirs,
successors, substitutes, and assigns. Where two or more persons have executed
the Documents, the obligations of such persons shall be joint and several,
except to the extent the context clearly indicates otherwise. The Documents
may be executed in any number of counterparts with the same effect as if all
parties had executed the same document. All such counterparts shall be
construed together and shall constitute one instrument, but in making proof
hereof it shall only be necessary to produce one such counterpart. Upon
receipt of an affidavit of an officer of Lender as to the loss, theft,
destruction or mutilation of any Document which is not of public record, and,
in the case of any mutilation, upon surrender and cancellation of the
Document, Borrower will issue, in lieu thereof, a replacement Document, dated
the date of the lost, stolen, destroyed or mutilated Document containing the
same provisions.

Section 9.07 Entire Agreement. Except as otherwise provided herein, (a) the
Documents constitute the entire understanding and agreement between Borrower
and Lender with respect to the Loan and supersede all prior written or oral
understandings and agreements with respect to the Loan including the Loan
application and Loan commitment and (b) Borrower is not relying on any
representations or warranties of Lender except as expressly set forth in the
Documents.

Section 9.08 WAIVER OF TRIAL BY JURY. BORROWER AND LENDER WAIVE, TO THE
FULLEST EXTENT PERMITTED BY LAW, THE RIGHT TO TRIAL BY JURY IN ANY ACTION,
PROCEEDING OR COUNTERCLAIM FILED BY EITHER PARTY, WHETHER IN CONTRACT, TORT OR
OTHERWISE, RELATING DIRECTLY OR INDIRECTLY TO THE LOAN, THE DOCUMENTS, OR ANY
ACTS OR OMISSIONS OF LENDER IN CONNECTION THEREWITH.

Section 9.09  New York Law Provisions.

         (a) Section 291-f Agreement. This Instrument is intended to be, and
shall operate as, the agreement described in Section 291-f of the Real

afforded thereby. Borrower shall (unless such notice is contained in such
tenant's Lease) deliver notice of this Instrument in form and substance
acceptable to Lender, to all present and future holders of any interest in any
Lease, by assignment or otherwise, and shall take such other action as may now
or hereafter be reasonably required to afford Lender the full protections and
benefits of Section 291-f. Borrower shall request the recipient of any such
notice to acknowledge the receipt thereof.

         (b) Trust Fund. Pursuant to Section 13 of the Lien Law of the State
of New York, Borrower shall receive the advances secured by this Instrument

on the Property before using any part of the total of the same for any other
purpose.

Instrument pursuant to the terms hereof, a court or other governmental
authority having jurisdiction at any time shall determine that this Instrument
falls within the ambit of Section 256 of the Tax Law of the State of New York,
then Lender reserves the right, in its discretion, to elect not to have such
additional sums secured by this Instrument and thereby reduce the Obligations
secured hereby to a definite amount equal to the principal amount of the Note,
interest thereon at the rate provided in the Note, plus any disbursements made
to protect the security of this Instrument, with interest on such
disbursements at the Default Rate, plus any such other sums as by statute or
judicial interpretation now or hereafter may be permitted to be secured by the
lien of a mortgage without incurring any additional mortgage recording tax.
Any election by Lender to so reduce the indebtedness secured by this
Instrument shall in no event be deemed a release, waiver or discharge by
Lender of Borrower's obligation to pay or reimburse Lender for such sums.

                           (ii)     Sums Deemed to be Interest.  Any sums,
late charges or liquidated damages, that may become due and payable pursuant
to the terms of the Note and/or this Instrument and that are in the nature of
interest (A) shall for the purpose of determining the amount of mortgage
recording tax due and payable on this Instrument, be considered as additional
interest, whether or not so denominated, (B) shall be secured by the lien of
this Instrument to the fullest extent possible without causing this Instrument
to be covered by Section 256 of the Tax Law of the State of New York, and (C)
shall not be deemed principal and shall not accrue any interest.

         (d) Assignment of Instrument. Upon payment in full of the
Obligations, Lender will execute and deliver, at Borrower's election and at
Borrower's direction, such customary and standard documents as may reasonably
be required to release, satisfy or assign this Instrument of record, provided
that Lender shall not be required to make any representations and warranties
therein other than a representation as to the then outstanding amount of the
Obligations.

IN WITNESS WHEREOF, the undersigned have executed this Instrument by their
respective duly authorized representative as of the date first set forth
above.

      THIS AMENDED, RESTATED AND CONSOLIDATED MORTGAGE NOTE (this "Note") by
SLG 100 PARK LLC, a Delaware limited liability company, having a principal
place of business at c/o SL Green Realty Corp., 420 Lexington Avenue, New
York, New York 10170 ("Borrower"), to the order of THE PRUDENTIAL INSURANCE
COMPANY OF AMERICA, a New Jersey corporation ("Lender", which shall also mean
successors and assigns who become holders of this Note), having an office c/o
Prudential Real Estate Investors, 8 Campus Drive, Arbor Circle South,
Parsippany, New Jersey 07054-4493.

                             W I T N E S S E T H:
                             - - - - - - - - - -

      WHEREAS, Lender is the owner and holder of a certain mortgage spread,
consolidated and modified by that certain Agreement of Spreader, Consolidation
and Modification of Mortgage of even date herewith between Borrower and Lender
(the mortgage spread, consolidated and modified thereby, the "Instrument";
capitalized terms used herein without definition shall have the respective
meanings ascribed to them in the Instrument), and of the note secured thereby
(collectively, the "Existing Note"); and

      WHEREAS, Borrower is the current obligor under the Existing Note; and

      WHEREAS, Borrower and Lender have agreed in the manner hereinafter set
forth (a) to adjust the interest rate on the Existing Note, (b) to change the
monthly payments on the Existing Note, and (c) to modify and restate in their
entirety all other terms and provisions of the Existing Note,

      NOW, THEREFORE, in consideration of the foregoing recitals, which are
incorporated into the operative provisions of this Note by this reference, and
for other good and valuable consideration, the receipt and adequacy of which
are hereby conclusively acknowledged, Borrower hereby represents and warrants
to and covenants and agrees with Lender as follows:

      A. Outstanding Indebtedness. The aggregate outstanding indebtedness
evidenced by the Existing Note and secured by the Instrument is One Hundred
Twelve Million Dollars ($112,000,000.00), it being understood that no interest
under the Existing Note is accrued and unpaid for the period prior to the date
hereof, but that interest shall accrue and be paid from and after the date
hereof at the rate or rates herein provided.

      B. Amendment and Restatement of Existing Note. The terms, covenants and
provisions of the Existing Note are hereby modified, amended and restated in
their entirety so that henceforth such terms, covenants and provisions shall
be those set forth herein, and the Existing Note, as so modified, amended and
restated, are hereby ratified and confirmed in all respects by Borrower. This
Note does not create any new or additional indebtedness but evidences the same
indebtedness evidenced by the Existing Note and secured by the Instrument.

      C. Borrower's Promise to Pay. FOR VALUE RECEIVED, Borrower promises to
pay to the order of Lender at its offices set forth above the principal sum of
One Hundred Twelve Million and No/100 U.S. Dollars ($112,000,000.00), with
interest on the unpaid balance ("Balance") at the rate of eight and
thirty-five one hundredths percent (8.35%) per annum ("Note Rate") from the
date hereof ("Funding Date") until Maturity (defined below.

      1.   Regular Payments.  Principal and interest shall be payable as
follows:

           (a) Interest from the Funding Date through January 31, 2000 shall
      be due and payable on the Funding Date.

           (b) Interest only shall be paid in arrears in monthly installments
      of Seven Hundred Seventy Nine Thousand Three Hundred Thirty-Three and
      33/100 Dollars ($779,333.33) each, commencing on March 1, 2000 and
      continuing on the first (1st) day of each succeeding month to and
      including January 31, 2002. Each payment due date is referred to as a
      "Due Date".

           (c) The entire unpaid Obligations (as defined in the Instrument)
      shall be due and payable on January 31, 2002 ("Maturity Date").
      "Maturity" shall mean the Maturity Date or earlier date that the
      Obligations may be due and payable by acceleration by Lender as provided
      in the Documents.

           (d) Interest on the Balance for any full month shall be calculated
      on the basis of a three hundred sixty (360) day year consisting of
      twelve (12) months of thirty (30) days each. For any partial month,
      interest due under this Note shall be computed hereunder with respect to
      each day during such period by multiplying the Balance at the close of
      business on each day (or on the most recent day that Lender was open for
      business) by a daily interest factor calculated by dividing the Note
      Rate by 360. Interest so computed shall accrue for each and every day
      during any partial month on which there is a Balance due hereunder and
      including the day on which funds are repaid.

      2.   Late Payment and Default Interest.

           (a) Late Charge. If any payment due under the Documents is not
      fully paid by its Due Date, a late charge of $500.00 per day (the "Daily
      Charge") shall be assessed for each day that elapses until payment in
      full is made (including the date payment is made); provided, however,
      that if any such payments, together with all accrued Daily Charges, are
      not fully paid by the fifteenth day following their Due Date, a late
      charge equal to four percent (4%) of such payments (the "Late Charge")
      shall be assessed and be immediately due and payable. The Late Charge
      shall be payable in lieu of Daily Charges that shall have accrued. The
      Late Charge may be assessed only once on each overdue payment. These
      charges shall be paid to defray the expenses incurred by Lender in
      handling and processing such delinquent payment(s) and to compensate
      Lender for the loss of the use of such funds. The Daily Charge and Late
      Charge shall be secured by the Documents. The imposition of the Daily
      Charge, Late Charge, and/or requirement that interest be paid at the
      Default Rate (defined below) shall not be construed in any way to (i)
      excuse Borrower from its obligation to make each payment under this Note
      promptly when due or (ii) preclude Lender from exercising any rights or
      remedies available under the Documents upon an Event of Default.

           (b) Acceleration. Upon an Event of Default, Lender may declare the
      Balance, unpaid accrued interest, and all other Obligations immediately
      due and payable in full.

           (c) Default Rate. Upon an Event of Default or at Maturity, whether
      by acceleration (due to a voluntary or involuntary default) or
      otherwise, the entire Obligations (excluding accrued but unpaid interest
      if prohibited by law) shall bear interest at the Default Rate. The
      "Default Rate" shall be the lesser of (i) the Maximum Rate (defined
      below) or (ii) the greater of (A) the Note Rate plus five percent (5%)
      or (B) five percent (5%) plus the prime rate (for corporate loans at
      large United States money center commercial banks) published in the Wall
      Street Journal on the first Business Day (defined below) of the month in
      which the Event of Default or Maturity occurs or continues. The term
      "Business Day" shall mean a day on which commercial banks or other
      institutional lenders are not authorized or required by Laws to close in
      the State of New York or in the State of New Jersey.

      3.   Application of Payments. Before an Event of Default, all payments
received under this Note shall be applied in the following order: (a) to
unpaid Daily Charges, Late Charges and costs of collection; (b) to interest on
the Balance; and (c) then to the Balance. After an Event of Default, all
payments shall be applied in any order determined by Lender in its sole
discretion.

      4.   Prepayment. This Note may be prepaid, in whole or in part at any time
upon payment of all accrued interest and other Obligations due under the
Documents. No prepayment premium or penalty will be assessed.

      5.   No Usury. Under no circumstances shall the aggregate amount paid or
to be paid as interest under this Note exceed the highest lawful rate
permitted under applicable usury law ("Maximum Rate"). If under any
circumstances the aggregate amounts paid on this Note shall include interest
payments which would exceed the Maximum Rate, Borrower stipulates that payment
and collection of interest in excess of the Maximum Rate ("Excess Amount")
shall be deemed the result of a mistake by both Borrower and Lender and Lender
shall promptly credit the Excess Amount against the Balance or refund to
Borrower any portion of the Excess Amount that cannot be so credited.

      6.   Security and Documents Incorporated. This Note is the Note referred
to and secured by the Instrument and is secured by the Property. Borrower
shall observe and perform all of the terms and conditions in the Documents.
The Documents are incorporated into this Note as if fully set forth in this
Note.

      7.   Treatment of Payments. All payments under this Note shall be made,
without offset or deduction, (a) in lawful money of the United States of
America at the office of Lender or at the place (and in the manner) Lender may
specify by written notice to Borrower, (b) in immediately available federal
funds, and (c) if received by Lender prior to 2:00 p.m. local time at such
place, shall be credited on that day or else, at Lender's option, shall be
credited on the next Business Day. Initially (unless waived by Lender), and
until Lender shall direct Borrower otherwise, Borrower shall make all payments
due under this Note in the manner set forth in Section 3.13 of the Instrument.
If any Due Date falls on a day that is not a Business Day, then the payment
shall be deemed to have fallen on the next succeeding Business Day.

      8.   Limited Recourse Liability. Except to the extent set forth in
Paragraph 8 and Paragraph 9 of this Note, neither the Borrower nor any members
of Borrower (singularly or collectively, the "Exculpated Parties") shall have
any personal liability for the Obligations. Notwithstanding the preceding
sentence, Lender may bring a foreclosure action or other appropriate action to
enforce the Documents or realize upon and protect the Property (including,
without limitation, naming the Exculpated Parties in the actions) and in
addition THE EXCULPATED PARTIES SHALL HAVE PERSONAL LIABILITY FOR:

           (a) any indemnity or similar instrument furnished in connection
      with the Loan;

           (b) any unpaid assessments and taxes with respect to the Property
      for the one year period prior to an Event of Default and thereafter,
      provided that income from the Property had been sufficient to pay the
      same;

           (c) any security deposits of Tenants not previously applied as
      permitted by the terms of the applicable Lease and (i) not turned over
      to Lender (or its designee) upon foreclosure, sale (pursuant to power of
      sale), or conveyance in lieu thereof in connection with a proceeding
      under the Bankruptcy Code or otherwise, or (ii) not turned over to a
      receiver or trustee for the Property after appointment;

           (d) any insurance proceeds or condemnation awards neither turned
      over to Lender (or its designee) nor used in compliance with Sections
      3.07 and 3.08, as applicable, of the Instrument;

           (e) waste of any material or significant portion of the Property
      that has not been expressly consented to by all members of Borrower
      and/or expressly consented to by Lender in writing;

           (f) any rents or other income from the Property received by any of
      the Exculpated Parties (other than Lender or any Affiliate of Lender who
      may be an Exculpated Party) after the occurrence of an event that with
      the giving of notice or passage of time or both would constitute an
      Event of Default under the Documents not otherwise applied to the
      Obligations evidenced by this Note, or current (not deferred) operating
      expenses of the Property; or (ii) is paid as expenses to a Person
      related to or affiliated with any of the Exculpated Parties (except

      are expressly permitted in the Documents; and

           (g) all reasonable legal fees, including the allocated costs of
      Lender's staff attorneys, and other expenses incurred by Lender in
      enforcing the Documents if Borrower contests, delays, or otherwise
      hinders or opposes (including the filing of a bankruptcy or equivalent
      action or proceeding) any of Lender's enforcement actions.

      9.   Full Recourse Liability. Notwithstanding the provisions of Paragraph
8 of this Note, the EXCULPATED PARTIES SHALL HAVE PERSONAL LIABILITY for all
of the Obligations if:

           (a) there shall be any breach or violation of Article V of the
      Instrument; or

           (b) there shall be any fraud or material misrepresentation by any
      of the Exculpated Parties (other than Lender or any Affiliate of Lender
      who may be an Exculpated Party) in connection with the Property, the
      Documents, or any other aspect of the Loan; or

           (c) the Property or any part thereof (other than a Lease of a
      Tenant who is not an Affiliate of any Exculpated Party) shall become an
      asset in (i) a voluntary bankruptcy or insolvency proceeding or (ii) an
      involuntary bankruptcy or insolvency proceeding that is not dismissed
      within ninety (90) days of filing; provided, however, that this
      Paragraph 9(c) shall not apply if an involuntary bankruptcy is filed by
      Lender in its capacity as Lender only.

several obligation of all makers, endorsers, guarantors and sureties, and
shall be binding upon them and their respective successors and assigns and
shall inure to the benefit of Lender and its successors and assigns.

      12. Changes in Laws Regarding Taxation. In the event of the passage of
any law of the State of New York, the City of New York, the County of New York
or any other applicable taxing authority deducting from the value of real
property for the purpose of taxation any lien or encumbrance thereon or
changing in any way the laws for the taxation of mortgages or debts secured by
mortgages for federal, state or local purposes or the manner of the collection
of any such taxes, and imposing a tax (other than a tax on income, revenue,
return of principal or reserves or the lack thereof), either directly or
indirectly, on the Instrument, this Note, any of the other Documents or the
Balance, Borrower shall, if permitted by law, pay any tax imposed as a result
of any such law within the statutory period or within thirty (30) days after
demand by Lender, whichever is less; provided, however, that if, in the
opinion of counsel for Lender, Borrower is not permitted by law to pay such
taxes, Lender shall have the right, at its option, to declare the Balance
immediately due and payable upon ninety (90) days' prior written notice to
Borrower.

      13. Documentary Stamps and Other Charges. Borrower shall pay all taxes
(excluding income, franchise and doing business taxes), assessments, charges,
expenses, costs and fees (including registration and recording fees and
revenue, stamp and other similar taxes) levied on, or assessed against Lender,
or otherwise required to be paid in connection with any of the Documents or
the Balance. If Borrower shall fail to promptly make such payments after
demand therefor, Lender shall have the right (but not the obligation) to pay
for the same and Borrower shall reimburse Lender therefor immediately upon
demand, with interest at the Default Rate. All such sums paid by Lender shall,
subject to the limitations set forth in Section 1.03 of the Instrument, be
secured by the Instrument.

      14. WAIVER OF TRIAL BY JURY. BORROWER HEREBY WAIVES, TO THE FULLEST
EXTENT PERMITTED BY LAW, THE RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING
OR COUNTERCLAIM FILED BY EITHER PARTY, WHETHER IN CONTRACT, TORT OR OTHERWISE,
RELATING DIRECTLY OR INDIRECTLY TO THE LOAN, THE DOCUMENTS, OR ANY ACTS OR
OMISSIONS OF LENDER IN CONNECTION THEREWITH.

US $112,000,000.00                                        February ____, 2000


      THIS AMENDED, RESTATED AND CONSOLIDATED MORTGAGE NOTE (this "Note") by
SLG 100 PARK LLC, a Delaware limited liability company, having a principal
place of business at c/o SL Green Realty Corp., 420 Lexington Avenue, New
York, New York 10170 ("Borrower"), to the order of THE PRUDENTIAL INSURANCE
COMPANY OF AMERICA, a New Jersey corporation ("Lender", which shall also mean
successors and assigns who become holders of this Note), having an office c/o
Prudential Real Estate Investors, 8 Campus Drive, Arbor Circle South,
Parsippany, New Jersey 07054-4493.

                             W I T N E S S E T H:

      WHEREAS, Lender is the owner and holder of a certain mortgage spread,
consolidated and modified by that certain Agreement of Spreader, Consolidation
and Modification of Mortgage of even date herewith between Borrower and Lender
(the mortgage spread, consolidated and modified thereby, the "Instrument";
capitalized terms used herein without definition shall have the respective
meanings ascribed to them in the Instrument), and of the note secured thereby
(collectively, the "Existing Note"); and

      WHEREAS, Borrower is the current obligor under the Existing Note; and

      WHEREAS, Borrower and Lender have agreed in the manner hereinafter set
forth (a) to adjust the interest rate on the Existing Note, (b) to change the
monthly payments on the Existing Note, and (c) to modify and restate in their
entirety all other terms and provisions of the Existing Note,

      NOW, THEREFORE, in consideration of the foregoing recitals, which are
incorporated into the operative provisions of this Note by this reference, and
for other good and valuable consideration, the receipt and adequacy of which
are hereby conclusively acknowledged, Borrower hereby represents and warrants
to and covenants and agrees with Lender as follows:

      A. Outstanding Indebtedness. The aggregate outstanding indebtedness
evidenced by the Existing Note and secured by the Instrument is One Hundred
Twelve Million Dollars ($112,000,000.00), it being understood that no interest
under the Existing Note is accrued and unpaid for the period prior to the date
hereof, but that interest shall accrue and be paid from and after the date
hereof at the rate or rates herein provided.

      B. Amendment and Restatement of Existing Note. The terms, covenants and
provisions of the Existing Note are hereby modified, amended and restated in
their entirety so that henceforth such terms, covenants and provisions shall
be those set forth herein, and the Existing Note, as so modified, amended and
restated, are hereby ratified and confirmed in all respects by Borrower. This
Note does not create any new or additional indebtedness but evidences the same
indebtedness evidenced by the Existing Note and secured by the Instrument.

      C. Borrower's Promise to Pay. FOR VALUE RECEIVED, Borrower promises to
pay to the order of Lender at its offices set forth above the principal sum of
One Hundred Twelve Million and No/100 U.S. Dollars ($112,000,000.00), with
interest on the unpaid balance ("Balance") at the rate of eight and
thirty-five one hundredths percent (8.35%) per annum ("Note Rate") from the
date hereof ("Funding Date") until Maturity (defined below.

      1.   Regular Payments.  Principal and interest shall be payable as
follows:

           (a) Interest from the Funding Date through February 29, 2000 shall
      be due and payable on the Funding Date.

           (b) Interest only shall be paid in arrears in monthly installments
      of Seven Hundred Seventy Nine Thousand Three Hundred Thirty-Three and
      33/100 Dollars ($779,333.33) each, commencing on March 1, 2000 and
      continuing on the first (1st) day of each succeeding month to and
      including February 28, 2002. Each payment due date is referred to as a
      "Due Date".

           (c) The entire unpaid Obligations (as defined in the Instrument)
      shall be due and payable on January 31, 2002 ("Maturity Date").
      "Maturity" shall mean the Maturity Date or earlier date that the
      Obligations may be due and payable by acceleration by Lender as provided
      in the Documents.

           (d) Interest on the Balance for any full month shall be calculated
      on the basis of a three hundred sixty (360) day year consisting of
      twelve (12) months of thirty (30) days each. For any partial month,
      interest due under this Note shall be computed hereunder with respect to
      each day during such period by multiplying the Balance at the close of
      business on each day (or on the most recent day that Lender was open for
      business) by a daily interest factor calculated by dividing the Note
      Rate by 360. Interest so computed shall accrue for each and every day
      during any partial month on which there is a Balance due hereunder and
      including the day on which funds are repaid.

      2.   Late Payment and Default Interest.
           ---------------------------------

           (a) Late Charge. If any payment due under the Documents is not
      fully paid by its Due Date, a late charge of $500.00 per day (the "Daily
      Charge") shall be assessed for each day that elapses until payment in
      full is made (including the date payment is made); provided, however,
      that if any such payments, together with all accrued Daily Charges, are
      not fully paid by the fifteenth day following their Due Date, a late
      charge equal to four percent (4%) of such payments (the "Late Charge")
      shall be assessed and be immediately due and payable. The Late Charge
      shall be payable in lieu of Daily Charges that shall have accrued. The
      Late Charge may be assessed only once on each overdue payment. These
      charges shall be paid to defray the expenses incurred by Lender in
      handling and processing such delinquent payment(s) and to compensate
      Lender for the loss of the use of such funds. The Daily Charge and Late
      Charge shall be secured by the Documents. The imposition of the Daily
      Charge, Late Charge, and/or requirement that interest be paid at the
      Default Rate (defined below) shall not be construed in any way to (i)
      excuse Borrower from its obligation to make each payment under this Note
      promptly when due or (ii) preclude Lender from exercising any rights or
      remedies available under the Documents upon an Event of Default.

           (b) Acceleration. Upon an Event of Default, Lender may declare the
      Balance, unpaid accrued interest, and all other Obligations immediately
      due and payable in full.

           (c) Default Rate. Upon an Event of Default or at Maturity, whether
      by acceleration (due to a voluntary or involuntary default) or
      otherwise, the entire Obligations (excluding accrued but unpaid interest
      if prohibited by law) shall bear interest at the Default Rate. The
      "Default Rate" shall be the lesser of (i) the Maximum Rate (defined
      below) or (ii) the greater of (A) the Note Rate plus five percent (5%)
      or (B) five percent (5%) plus the prime rate (for corporate loans at
      large United States money center commercial banks) published in the Wall
      Street Journal on the first Business Day (defined below) of the month in
      which the Event of Default or Maturity occurs or continues. The term
      "Business Day" shall mean a day on which commercial banks or other
      institutional lenders are not authorized or required by Laws to close in
      the State of New York or in the State of New Jersey.

     3.   Application of Payments. Before an Event of Default, all payments
received under this Note shall be applied in the following order: (a) to
unpaid Daily Charges, Late Charges and costs of collection; (b) to interest on
the Balance; and (c) then to the Balance. After an Event of Default, all
payments shall be applied in any order determined by Lender in its sole
discretion.

     4.   Prepayment. This Note may be prepaid, in whole or in part at any time
upon payment of all accrued interest and other Obligations due under the
Documents. No prepayment premium or penalty will be assessed.

      5.  No Usury. Under no circumstances shall the aggregate amount paid or
to be paid as interest under this Note exceed the highest lawful rate
permitted under applicable usury law ("Maximum Rate"). If under any
circumstances the aggregate amounts paid on this Note shall include interest
payments which would exceed the Maximum Rate, Borrower stipulates that payment
and collection of interest in excess of the Maximum Rate ("Excess Amount")
shall be deemed the result of a mistake by both Borrower and Lender and Lender
shall promptly credit the Excess Amount against the Balance or refund to
Borrower any portion of the Excess Amount that cannot be so credited.

     6.  Security and Documents Incorporated. This Note is the Note referred to
and secured by the Instrument and is secured by the Property. Borrower shall
observe and perform all of the terms and conditions in the Documents. The
Documents are incorporated into this Note as if fully set forth in this Note.

      7. Treatment of Payments. All payments under this Note shall be made,
without offset or deduction, (a) in lawful money of the United States of
America at the office of Lender or at the place (and in the manner) Lender may
specify by written notice to Borrower, (b) in immediately available federal
funds, and (c) if received by Lender prior to 2:00 p.m. local time at such
place, shall be credited on that day or else, at Lender's option, shall be
credited on the next Business Day. Initially (unless waived by Lender), and
until Lender shall direct Borrower otherwise, Borrower shall make all payments
due under this Note in the manner set forth in Section 3.13 of the Instrument.
If any Due Date falls on a day that is not a Business Day, then the payment
shall be deemed to have fallen on the next succeeding Business Day.

      8. Limited Recourse Liability. Except to the extent set forth in
Paragraph 8 and Paragraph 9 of this Note, neither the Borrower nor any members
of Borrower (singularly or collectively, the "Exculpated Parties") shall have
any personal liability for the Obligations. Notwithstanding the preceding
sentence, Lender may bring a foreclosure action or other appropriate action to
enforce the Documents or realize upon and protect the Property (including,
without limitation, naming the Exculpated Parties in the actions) and in
addition THE EXCULPATED PARTIES SHALL HAVE PERSONAL LIABILITY FOR:

           (a)  any indemnity or similar instrument furnished in connection
      with the Loan;

           (b) any unpaid assessments and taxes with respect to the Property
      for the one year period prior to an Event of Default and thereafter,
      provided that income from the Property had been sufficient to pay the
      same;

           (c) any security deposits of Tenants not previously applied as
      permitted by the terms of the applicable Lease and (i) not turned over
      to Lender (or its designee) upon foreclosure, sale (pursuant to power of
      sale), or conveyance in lieu thereof in connection with a proceeding
      under the Bankruptcy Code or otherwise, or (ii) not turned over to a
      receiver or trustee for the Property after appointment;

           (d) any insurance proceeds or condemnation awards neither turned
      over to Lender (or its designee) nor used in compliance with Sections
      3.07 and 3.08, as applicable, of the Instrument;

           (e) waste of any material or significant portion of the Property
      that has not been expressly consented to by all members of Borrower
      and/or expressly consented to by Lender in writing;

           (f) any rents or other income from the Property received by any of
      the Exculpated Parties (other than Lender or any Affiliate of Lender who
      may be an Exculpated Party) after the occurrence of an event that with
      the giving of notice or passage of time or both would constitute an
      Event of Default under the Documents not otherwise applied to the
      Obligations evidenced by this Note, or current (not deferred) operating
      expenses of the Property; or (ii) is paid as expenses to a Person
      related to or affiliated with any of the Exculpated Parties (except
      payments made to Lender under the Loan Documents) unless the payments
      are expressly permitted in the Documents; and

           (g) all reasonable legal fees, including the allocated costs of
      Lender's staff attorneys, and other expenses incurred by Lender in
      enforcing the Documents if Borrower contests, delays, or otherwise
      hinders or opposes (including the filing of a bankruptcy or equivalent
      action or proceeding) any of Lender's enforcement actions.

      9.   Full Recourse  Liability.  Notwithstanding  the  provisions of
Paragraph 8 of this Note,  the EXCULPATED PARTIES SHALL HAVE PERSONAL LIABILITY
for all of the Obligations if:

           (a)  there shall be any breach or violation of Article V of the
      Instrument; or

           (b) there shall be any fraud or material misrepresentation by any
      of the Exculpated Parties (other than Lender or any Affiliate of Lender
      who may be an Exculpated Party) in connection with the Property, the
      Documents, or any other aspect of the Loan; or

           (c) the Property or any part thereof (other than a Lease of a
      Tenant who is not an Affiliate of any Exculpated Party) shall become an
      asset in (i) a voluntary bankruptcy or insolvency proceeding or (ii) an
      involuntary bankruptcy or insolvency proceeding that is not dismissed
      within ninety (90) days of filing; provided, however, that this
      Paragraph 9(c) shall not apply if an involuntary bankruptcy is filed by
      Lender in its capacity as Lender only.
