ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS

         On May 24, 1999, SL Green Realty Corp. (the "Company"), acquired the
fee interests in four New York City office properties from Reckson Associates
Realty Corp. ("Reckson"), comprising 675,000 square feet for $84.5 million in
cash. The properties include an entire blockfront in midtown Manhattan between
40th and 41st Streets along Madison Avenue (286, 290 and 292 Madison Avenue),
and 90 Broad Street in downtown Manhattan.

         The purchase price for the transaction was obtained through financing
arrangements made with Prudential Securities Credit Corp. ("PSCC") and German
American Capital Corporation, an affiliate of Deutsche Bank ("German
American"). PSCC provided a mortgage loan in the amount of $51.7 million, for
a term of one year. German American provided a mortgage loan of $35 million
secured by the Company's interest in the Graybar Building, having a term of
two years. Each of the PSCC and German American loans were secured by
interests in other properties owned by the Company. Excess funds not used to
acquire the properties from Reckson will be used to repay a part of the
outstanding balance of the Company's unsecured line of credit.

               SECTION 3: TRANSFER OF PROPERTY; MERGER; CLOSING

     Section 3.01. Contemporaneously with the consummation of the Merger, the
Seller agrees to sell (and to cause the other Seller Parties or the Tower
Entities to sell) to Purchaser, and Purchaser agrees to purchase from the
Seller, subject to and in accordance with the terms, provisions, covenants and
conditions set forth in this Agreement, all of the Seller Parties' interest in
the Property for a purchase price of EIGHTY-FOUR MILLION FIVE HUNDRED THOUSAND
AND NO/100 DOLLARS ($84,500,000) (the "PURCHASE PRICE") subject to adjustments
to be made as provided in this Agreement, including, without limitation, as
provided in Section 7 hereof. The Purchase Price to be paid by the Purchaser
shall be paid as follows:

               (a) FIVE MILLION AND NO/100 DOLLARS ($5,000,000) on the signing
of this Agreement as the downpayment (the "DOWNPAYMENT"), by certified check
or wire to the Escrow Agent; provided; however, that the Purchaser shall have
the right to deliver a letter of credit in the amount of $5,000,000 as the
Downpayment (the "LC"), or, at any time after the date hereof (provided that
Purchaser is not then in default under this Agreement) and upon one (1)
Business Days' prior notice to Seller and Escrow Agent, deliver a letter of
credit in substitution of the cash Downpayment and any interest then earned
thereon (in which event the cash Downpayment together with any interest then
earned thereon shall be contemporaneously therewith returned to Purchaser)
(the "SUBSTITUTE LC") which LC or Substitute LC, as the case may be, shall be
in form and from an institution as set forth in Exhibit F attached hereto and
made a part hereof. The Downpayment shall be held by the Escrow Agent in
accordance with Section 25 hereof. At Closing, all interest earned on the
Downpayment, if any, shall be credited by the Seller to the Purchase Price.

               (b) Subject to the adjustments hereinafter set forth,
SEVENTY-NINE MILLION FIVE HUNDRED THOUSAND AND NO/100 DOLLARS ($79,500,000) on
the Closing Date; provided, however, that in the event the Downpayment is in
the form of a letter of credit , at Closing, the letter of credit shall be
returned to Purchaser and the amount otherwise payable by Purchaser under this
clause (b) shall be increased by the amount of the letter of credit.

     Section 3.02. All monies payable under this Agreement on the Closing Date
shall be delivered by wire transfer to an account or accounts designated by
Seller.

     Section 3.03. Notwithstanding anything herein to the contrary, Purchaser
acknowledges that Seller's obligations under this Agreement are contingent on
the consummation of the Merger. Accordingly, Purchaser acknowledges that if
the Merger fails to occur for any reason whatsoever, then (i) the Deposit
shall promptly be returned to the Purchaser and (ii) the Seller's obligations
under this Agreement shall terminate and be of no force and effect; provided,
however, that if ROP and/or Reckson willfully causes Seller not to consummate
the Merger, then Seller, ROP and/or Reckson shall reimburse Purchaser for all
costs and expenses incurred by Purchaser in connection with this Agreement,
including without limitation, all attorneys fees incurred by Purchaser;
provided, further, that Seller's, ROP's and/or Reckson's obligations with
respect to such costs and expenses shall not exceed $200,000 in the aggregate
plus the costs and expenses (not to exceed $18,000) of any vendee's title
insurance policy obtained by Purchaser.

     Section 3.04. The Closing shall occur contemporaneously with the Merger
(time being of the essence); provided, however, that in no event shall the
Closing Date occur prior to March 15, 1999; and, provided further, that (i) if
the Merger shall not have occurred on or before June 30, 1999, Purchaser may
terminate this Agreement by written notice delivered to Seller no later than
July 10, 1999 (it being understood that, except as otherwise provided herein,
if Purchaser does not elect to terminate this Agreement on or before July 10,
1999, Purchaser shall be deemed to have waived its right to terminate this
Agreement for the reason of the Merger not occurring on or before June 30,
1999) and (ii) either Seller or Purchaser may thereafter cancel this Agreement
if the Merger shall not have occurred on or before August 31, 1999, and upon
such cancellation the Deposit shall promptly be returned to Purchaser. Seller
acknowledges that it shall not be entitled to cancel this Agreement pursuant
to clause (ii) of this Section 3.04 if the Merger has not occurred on or
before August 31, 1999 primarily because Seller is attempting to circumvent
its obligation to convey the Properties to Purchaser because Seller has
received, or believes it can receive, a better offer for any Property. The
Purchaser acknowledges that Seller would not have entered into this Agreement
if Purchaser had not agreed to close simultaneously with the Merger.
Notwithstanding the foregoing, Seller shall have the right, upon five (5)
Business Days prior written notice, to require Purchaser to close prior to the
Merger (but in no event earlier than March 15, 1999) in order to minimize
certain transfer taxes which would otherwise be due.

                    SECTION 4: DUE DILIGENCE; "AS IS" SALE

     Section 4.01. Purchaser acknowledges that it has had sufficient
opportunity to examine the Property, that Purchaser has availed itself of that
opportunity and that Purchaser is fully familiar with the Property and the
condition thereof. Purchaser agrees to purchase the Property "AS IS" and
agrees that Seller shall be required to perform no work or expend any funds in
connection with the Property in preparation for Closing except as expressly
herein set forth to the contrary and except that Seller shall pay at Closing
for all Facade Work with respect to the Madison Properties which has been
completed as of the date of the Closing and all work which is to be completed
pursuant to the Current Facade Contracts and for which payment has not been
made at Closing. Notwithstanding the foregoing, Seller acknowledges that the
Facade Work may need to be completed with respect to the Madison Properties
subsequent to Closing. Seller and Purchaser agree that any uncompleted Facade
Work at Closing shall be performed by Purchaser (or its agents) subsequent to
the Closing at Seller's expense, which expense to Seller shall not exceed
one-half of the final cost of the Facade Work but in no event in an amount in
excess of the Facade Work Amount (together with any interest earned thereon).
At Closing, Seller shall deposit with Greenberg Traurig, as disbursing agent
(the "DISBURSING AGENT") an amount equal to the Facade Work Amount to be held
by Disbursing Agent in accordance with the terms of a deposit and disbursing
agreement, in the form attached as Exhibit K hereto (the "Deposit and
Disbursing Agreement"). Purchaser agrees that the Facade Work Amount deposited
with Disbursing Agent may, at Seller's option, be a credit to Purchaser at
Closing thereby reducing the Purchase Price. Purchaser acknowledges that
Seller has made no representations with respect to the facade of the Madison
Properties or any work which may be required thereon and agrees that Seller
shall have no liability to Purchaser in connection therewith except as
expressly set forth in this Section 4.01.

     Section 4.02. Seller shall use reasonable efforts during the Contract
Period to cause the applicable Tower Entities to permit Purchaser and its
authorized agents, employees and other representatives, upon prior reasonable
notice to the Seller, access to the Property for the purpose of inspecting the
Property and the Seller and/or the Tower Entities and or their representatives
shall have the right to be present during such inspections. Purchaser shall
not interfere with the use or operation of the Property during such
inspections. Purchaser shall indemnify, defend and hold harmless the Seller
and the Tower Entities from and against any and all loss, costs, liability,
damage and expenses, including, but not limited to, penalties, fines, court
costs, disbursements and reasonable attorney's fees incurred in connection
with or arising from injuries to persons or damage to property caused by
Purchaser, its agents, employees, representatives or independent contractors
with respect to such right of access. The provisions of this Section shall be
binding upon Purchaser regardless of whether or not the transactions
contemplated hereby are consummated and shall survive for a one-year period
following the termination of this Agreement or the Closing, as applicable.

               SECTION 5: MATTERS TO WHICH THE SALE IS SUBJECT

     Section 5.01. The Seller shall assign and convey or cause to be assigned
and conveyed to Purchaser good and valid insurable fee title to the Properties
free and clear of any and all mortgages, liens, leases, encumbrances and
easements, except:

     (a) All taxes, water meter and water charges and sewer rents, accrued or
unaccrued, fixed or not fixed, becoming due and payable after the Closing
Date;

     (b) All zoning laws and building ordinances, resolutions, regulations and
orders (including any violation orders) of all boards, bureaus, commissions
and bodies of any municipal, county, state or federal government;

     (c) All Leases; and

     (d) The Permitted Encumbrances.

                         SECTION 6: RECORDED MORTGAGE

     Section 6.01. Subject to Section 6.02 hereof, Seller agrees to cause the
payoff of any mortgage recorded against all or a portion of any Property
subsequent to the date hereof (the "RECORDED MORTGAGE").

     Section 6.02. If at the Closing any Property is encumbered by a Recorded
Mortgage, then Seller shall discharge same or cause the Title Insurer to omit
such Recorded Mortgage from Purchaser's and Purchaser's lender's title
insurance policy, provided, however, that in no event shall Seller have the
obligation to discharge any Recorded Mortgage if the amount outstanding
thereunder exceeds $3,000,000 (unless a Merger Party is the signatory of such
Recorded Mortgage). If a Recorded Mortgage exceeding $3,000,000 is encumbering
any Property and Seller elects not to discharge the same or cause the Title
Insurer to omit such Recorded Mortgage from the title insurance policy, then
Purchaser shall have the right to terminate this Agreement whereupon the
Deposit shall be returned to Purchaser and neither party shall have any
further rights against the other except that the provisions of Section 15
hereof shall survive such termination.

                            SECTION 7: ADJUSTMENTS

     Section 7.01. The following apportionments shall be made between the
parties at the Closing, at Purchaser's election, either (x) as of 11:59 p.m.
on the day preceding the first day of the month in which the Closing Date
occurs or (y) as of 11:59 p.m. on the day prior to the Closing Date (the
parties agreeing that Purchaser may make such election solely as a matter of
administrative convenience and that the exercise of such election shall not
impact the net economics benefits of the apportionments due Seller
contemplated by this Agreement as between Seller and Purchaser) based upon the
respective party's period of ownership for the item being apportioned:

     (a) prepaid rents and Additional Rents (as hereinafter defined);

     (b) real estate taxes, water charges, sewer rents and vault charges, if
any, on the basis of the fiscal period for which assessed, except that if
there is a water meter on any Property, apportionment at the Closing shall be
based on the last available reading, subject to adjustment after the Closing
when the next reading is available;

     (c) wages, vacation pay, pension and welfare benefits and other fringe
benefits of all persons employed at the Property whose employment was not
terminated by Seller at or prior to the Closing;

     (d) value of fuel and maintenance supplies stored on the Property, at the
price then charged by Seller's supplier, including any taxes (if requested by
Purchaser, post-Closing, Seller shall deliver a statement from Seller's
supplier as to such value);

     (e) any other item which is customarily apportioned at Closing in
connection with sales of similar property in New York City;

     (f) charges payable under Service Contracts on the basis of the period
covered by such payments except that Seller shall pay in full on or before the
Closing, and shall deliver satisfactory evidence of payment thereof to
Purchaser at Closing, all sums due for the installation and upgrade of the
"class e system" at the 90 Broad Property under that certain Service Contract
with Firequench dated June 17, 1997;

     If the Closing shall occur before a new tax rate is fixed, the
apportionment of taxes at the Closing shall be upon the basis of the old tax
rate for the preceding period applied to the latest assessed valuation.
Promptly after the new tax rate is fixed for the fiscal period in which the
Closing takes place, the apportionment of taxes shall be recomputed. Any
discrepancy resulting from such recomputation shall be promptly paid to the
other party, which obligation shall survive the Closing.

     Section 7.02. If any tenant is in arrears in the payment of rent on the
Closing Date, rents received from such tenant after the Closing shall be
applied in the following order of priority: (a) first to the month in which
the Closing occurred; (b) then to the month preceding the month in which the
Closing occurred; (c) then to any month or months following the month in which
the Closing occurred; and (d) then to any other rents which were delinquent at
Closing with respect to the period prior to the month preceding the month in
which the Closing occurred. If rents or any portion thereof received by Seller
or Purchaser after the Closing are payable to the other party by reason of
this allocation, the appropriate sum, less a proportionate share of any
reasonable attorney's fees, costs and expenses of collection thereof, shall be
promptly paid to the other party, which obligation shall survive the Closing.
Purchaser shall use commercially reasonable efforts to collect any arrearages
due Seller, provided, however, that "commercially reasonable" shall not be
construed to require Purchaser to dispossess any tenant on account of any
arrearage due Seller.

     Section 7.03. If any tenants are required to pay percentage rent,
escalation charges for real estate taxes, operating expenses, cost-of-living
adjustments or other charges of a similar nature ("ADDITIONAL RENTS") and any
Additional Rents are collected by Purchaser after the Closing which are
attributable in whole or in part to any period prior to the Closing, then
Purchaser shall promptly pay to Seller, Seller's proportionate share thereof,
less a proportionate share of any reasonable attorneys' fees, costs and
expenses of collection thereof, if and when the tenant paying the same has
made all payments of rent and Additional Rent then due to Purchaser pursuant
to the tenant's Lease, which obligation shall survive the Closing. If any
Additional Rents are collected by Seller or for the benefit of Seller which
are attributable in whole or part to any period on or after the Closing Date,
then Seller shall promptly pay to Purchaser, Purchaser's proportionate share
thereof less a proportionate share of reasonable attorneys' fees, costs and
expenses of collection thereof.

     Section 7.04. Except as otherwise provided herein, "Customs in Respect to
Title Closings" recommended by the Real Estate Board of New York, Inc. shall
apply to the apportionments set forth herein. If, after the Closing, an error
or omission in the calculation of the apportionments set forth above is found
by one of the parties, such error or omission shall be promptly corrected and
the party receiving the over-payment shall pay the amount of the over-payment
to the party entitled thereto. Subject to the following sentence, the
foregoing obligation to correct apportionments shall survive the Closing for a
period of one-hundred and eighty (180) days (the "POST-CLOSING ADJUSTMENT
PERIOD"). After the Post-Closing Adjustment Period, either party may deliver
to the other a written notice (an "ADJUSTMENT TERMINATION NOTICE") terminating
the Post-Closing Adjustment Period. The party which receives the Adjustment
Termination Notice may, within ten (10) Business Days after receipt of the
same, deliver to the other party a letter (a "PROTEST NOTICE") protesting the
termination of the Post-Closing Adjustment Period and proposing a final
post-Closing adjustment reconciliation, while setting forth in detail the
method of calculating such adjustment reconciliation. Failure to deliver a
Protest Notice on or before the tenth (10th) day after receipt of an
Adjustment Termination Notice shall be deemed consent to and termination of
the Post-Closing Adjustment Period. If a Protest Notice is timely delivered
after receipt of an Adjustment Termination Notice or, if prior to the
termination of the Post-Closing Adjustment Period a party proposes an
adjustment which is disputed by the other party, the parties shall attempt for
thirty (30) days thereafter to agree on such disputed adjustment, after which
thirty (30) day period either party may submit the matter to the American
Arbitration Association for resolution in accordance with the Arbitration
Rules for the Real Estate Industry, as amended and effective on May 1, 1994.

     Section 7.05. To the extent that any brokerage fees or commissions
(collectively, "COMMISSIONS") are due after the Closing Date in connection
with Leases executed prior to the date of this Agreement, Seller shall be
responsible for the payment of the same and Seller shall promptly pay any such
Commissions as they become due; provided, however, that Seller shall not be
responsible for paying any Commissions which may be due with respect to any
renewal options contained in any such Leases or any expansion of leased
premises. Notwithstanding anything contained herein to the contrary, Seller
and Purchaser acknowledge and agree that Seller's assignment of, and
Purchaser's acceptance of, the Brokerage Agreements shall be expressly subject
to Seller's obligations under this Section 7.05 and Section 14.02 hereof.

     Section 7.06. The provisions of this Section 7 shall survive the Closing.

                             SECTION 8: CASUALTY

     Section 8.01. If, on or prior to the date of the Closing, all or a
"MATERIAL PART" (as defined below) of any Property shall be damaged or
destroyed by fire or other casualty, then, in any such event, Purchaser may,
at its option, either (i) cancel this Agreement, whereupon subject to Section
25, the Deposit shall be returned to Purchaser and the parties hereto shall be
released of all obligations and liabilities of whatsoever nature in connection
with this Agreement except that the provisions of Section 15 hereof shall
survive, or (ii) proceed to close the transactions contemplated by this
Agreement, in which event all of the provisions of subsection 8.01(a)(i) and
subsection 8.01(a)(ii) below shall apply.

     (a) If, on or prior to the date of the Closing, less than a material part
of any Property shall be destroyed or damaged by fire or other casualty
Purchaser shall nevertheless close title to all of the Properties pursuant to
all the terms and conditions of this Agreement (without any adjustment to the
Purchase Price except as otherwise set forth herein), subject to the
following: (i) No Seller Party shall (x) adjust and settle any insurance
claims, or (y) enter into any construction or other contract for the repair or
restoration of the Property without Purchaser's prior written consent, which
consent shall not be unreasonably withheld or delayed, and (ii) at the
Closing, the Seller shall (1) pay over to Purchaser the amount of any
insurance proceeds, to the extent collected by any Seller Party in connection
with such casualty, less the amount of the actual and reasonable unreimbursed
expenses incurred by such Seller Party in connection with collecting such
proceeds and making any repairs to the Property occasioned by such casualty
pursuant to any contract (provided that such contract was reasonably approved
by Purchaser as required by this Section), (2) assign to Purchaser in form
reasonably satisfactory to Purchaser all of the Seller's right, title and
interest in and to any insurance proceeds that are uncollected at the time of
the Closing and that may be paid in respect of such casualty and (3) pay over
to Purchaser a sum equal to the amount of the deductible, if any, on the
applicable insurance policy for the Property. The Seller shall reasonably
cooperate with Purchaser in the collection of such proceeds, which obligation
shall survive the Closing.

     (b) For the purpose of this Section, the phrase a "MATERIAL PART" of an
Improvement shall mean a portion of an Improvement such that the cost of
repair or restoration thereof is estimated by a reputable contractor selected
by the Seller and reasonably satisfactory to Purchaser, to be in excess of
Five Million and 00/100 Dollars ($5,000,000).

                   SECTION 9: CONDEMNATION PENDING CLOSING

     Section 9.01. If, prior to the Closing Date, condemnation or eminent
domain proceedings shall be commenced by any competent public authority
against the Real Property or any part thereof, the Seller shall promptly give
Purchaser written notice thereof. After notice of the commencement of any such
proceedings (from the Seller or otherwise) and in the event that the taking of
such property is "Material" (as hereinafter defined), Purchaser shall have the
right (i) to accept title to the Property subject to the proceedings,
whereupon any award payable to the Seller Parties shall be paid to Purchaser
and the Seller Parties shall deliver to Purchaser at the Closing all
assignments and other documents reasonably requested by Purchaser to vest such
award in Purchaser, or (ii) to rescind this Agreement and upon the return of
the Deposit, this Agreement shall be null and void and neither party will have
any further obligations hereunder except that the provisions of Section 15
hereof shall survive. A taking shall be deemed to be Material if said taking
materially and adversely affects access to any of the Properties, or leaves a
remaining balance of any Property which may not be economically operated for
the purpose for which the Property was operated prior to such taking, or if in
the reasonable estimation of an appraiser selected by Seller, subject to
Purchaser's reasonable approval, the taking would result in a claim for
condemnation proceeds equal to or in excess of Five Million and 00/100 Dollars
($5,000,000).

     Section 9.02. In the event of a non-Material taking of any part of the
Real Property, Purchaser shall accept the Real Property subject to the
proceedings and pay to the Seller the full Purchase Price, whereupon any award
payable to any Seller Party shall be paid to Purchaser and such Seller Party
shall deliver to Purchaser at the Closing all assignments and other documents
reasonably requested by Purchaser to vest such award in Purchaser.

            SECTION 10: THE SELLER'S WARRANTIES AND REPRESENTATIONS

specifically acknowledged that (i) if any information is disclosed in writing
to Purchaser on or prior to the date hereof by the Seller Parties or the Tower
Entities (or either of their attorneys, accountants, consultants or other
professionals) (or is the subject of correspondence between the Seller Parties
or the Tower Entities and Purchaser) which indicates that a representation
made by Seller in this Agreement is untrue (it being agreed that Purchaser
shall be deemed to have received written disclosure with respect to any matter
contained in the materials made available to Purchaser in the due diligence
room at the offices of Skadden, Arps, Slate, Meagher and Flom prior to signing
this Agreement), Seller shall have no liability with respect to such

of title hereunder, to record the deeds or as may be reasonably requested by
the Title Insurer;

     (g) the Assignment Agreement substantially in the form of Exhibit D
attached hereto and made a part hereof, together with original executed
counterparts, to the extent originals are in Seller's possession, or, if
originals are not in Seller's possession, copies (to the extent that copies
are in Seller's possession) of all Leases, Service Contracts, Books and
Records and Brokerage Agreements, if any;

     (h) all Security Deposits actually held by the Tower Entities at Closing,
together with all accrued interest thereon actually held by the Tower Entities
at Closing, by payment of the amount thereof to Purchaser or by a credit to
Purchaser against the Purchase Price, and with respect to any Security
Deposits which are other than cash or that are in the form of a letter of
credit (collectively, the "NON-CASH SECURITY DEPOSITS"), by way of appropriate
instruments of transfer or assignment of such Non-Cash Security Deposits which
are required to transfer such Non-Cash Security Deposits to Purchaser as the
new beneficiary thereunder, provided, however, that if Seller lacks sufficient
information, or is otherwise unable, at Closing, to make the deliveries
hereunder, Seller shall make such deliveries as promptly after Closing as
practicable, but in no event later than the day that is three (3) months after
the Closing Date. Seller shall reasonably cooperate with Purchaser to prevent
the expiration of any Non-Cash Security Deposits prior to the transfer of the
same to Purchaser and to facilitate the recognition by the issuer of such
instrument of Purchaser as the beneficiary of any letter of credit or other
form of Non-Cash Security Deposits;

     (i) a closing statement setting forth all apportionments to be made at
Closing together with disbursement instructions for payment of the balance of
the Purchase Price;

     (j) notice to the Tenants, advising them of the sale of the Properties to
Purchaser, substantially in the form of Exhibit G attached hereto and made a
part hereof.

            SECTION 12: PURCHASER'S REPRESENTATIONS AND WARRANTIES

     Section 12.01. To induce the Seller to enter into this Agreement,
Purchaser makes the following representations and warranties, all of which
Purchaser represents are true in all material respects as of the date hereof
and shall be true in all material respects as of the Closing Date and shall be
deemed to be made as of that date.

     (a) The execution, delivery and performance of this Agreement and
consummation of the transaction hereby contemplated in accordance with the
terms of this Agreement will not violate any material contract, agreement,
commitment, order, judgment or decree to which Purchaser is a party or by
which it is bound, and Purchaser has obtained (or will, by the Closing, have
obtained) all consents necessary (whether from a governmental authority or
other third party) in order for it to consummate the transactions contemplated
hereby.

     (b) The party or parties executing this Agreement on behalf of Purchaser
have been duly authorized and are empowered to bind Purchaser to this
Agreement and to take all actions required by this Agreement.

     (c) Upon execution, this Agreement shall be the binding obligation of
Purchaser, enforceable against Purchaser in accordance with the terms hereof.

     (d) No action, suit or proceeding is pending or, to Purchaser's
knowledge, threatened against Purchaser which would materially adversely
affect Purchaser's financial condition or its ability to fully perform its
obligations pursuant to this Agreement.

     (e) The execution and delivery of this Agreement and the performance by
Purchaser of its obligations hereunder do not and will not conflict with or
violate any law, rule, judgment, regulation, order, writ, injunction or decree
of any court or governmental or quasi-governmental entity with jurisdiction
over Purchaser, including, without limitation, the United States of America,
the State of New York or any political subdivision of any of the foregoing, or
any decision or ruling of any arbitrator to which Purchaser is a party or by
which Purchaser is bound or affected and no consent of any governmental agency
is required.

     All representations and warranties of Purchaser contained in this
Agreement shall survive the Closing for a period of four (4) months.

                SECTION 13: PURCHASER'S INSTRUMENTS AT CLOSING

     Section 13.01. On the Closing Date, Purchaser shall deliver the Purchase
Price, as adjusted, to the Seller. Additionally, on the Closing Date,
Purchaser shall duly execute, acknowledge and deliver to the Seller the
following:

     (a) real estate transfer tax forms and returns, if any, for the Property;

     (b) the Assignment Agreement in the form of Exhibit D attached hereto

     (c) a closing statement setting forth all apportionments to be made at
Closing together with disbursement instructions for payment of the balance of
the Purchaser Price; and

     (d) such other documents, instruments, resolutions and other material as
may be necessary to effect the transfer of title hereunder and reasonably
requested by the Seller or the Title Insurer.

                         SECTION 14: CONTRACT PERIOD

     Section 14.01. Purchaser shall have the benefit of any consent and/or
approval rights (the "CONSENT RIGHTS") granted to any of the Merger Parties
under the Merger Agreement with respect to any matters affecting any of the
Properties and/or any Leases or proposed leases; provided, however, that
Purchaser acknowledges that if none of the Merger Parties have any Consent
Rights with respect to a particular matter and/or any Lease or proposed lease
or if Tower or Tower Realty fail to allow the Merger Parties or Purchaser to
exercise any Consent Rights, then Purchaser shall still be obligated to
purchase the Property, subject to Purchaser's rights pursuant to Section
16.01(i) hereof. Notwithstanding anything to the contrary herein set forth, in
the event that: (i) the Tower Entities provide the Consent Rights to the
Merger Parties; (ii) the Merger Parties fail to provide such Consent Rights to
Purchaser; and (iii) Purchaser incurs a Loss as a result of Seller's failure
to provide such Consent Rights to Purchaser; then, in such event, Purchaser
shall be obligated to consummate the Closing without any adjustment in the
Purchase Price if the Loss resulting therefrom is equal to or less than
$250,000; provided, however, that if such Loss is greater than $250,000, then
Purchaser shall be entitled to a credit to the Purchase Price to the extent
such Loss exceeds $250,000 but in no event shall the credit given to Purchaser
under this sentence exceed $1,250,000.

     Section 14.02. Seller and Purchaser agree that all leasing costs
including, without limitation, capital improvements, tenant improvements and
Commissions (collectively, "SELLER LEASE PAYMENTS") paid in connection with
any Lease executed during the Contract Period shall be credited to Seller as
an increase in the Purchase Price. Purchaser hereby indemnifies and holds
Seller harmless from and against any and all claims, loss, liability, damages,
cost or expense, including reasonable attorney fees, that may arise in
connection with any Seller Lease Payments paid in connection with any Lease
executed during the Contract Period. Any Seller Lease Payments incurred in
connection with any Lease signed prior to the date hereof which are unpaid on
the Closing Date shall be credited to Purchaser and the Purchase Price shall
be decreased accordingly and Seller hereby indemnifies and holds Purchaser
harmless from and against any and all claims, loss, liability, damages, cost
or expense, including reasonable attorney fees, that may arise in connection
with any Seller Lease Payments incurred in connection with any Lease signed
prior to the date hereof which are unpaid on the Closing Date.

     Section 14.03. Subject to the limitation of Seller's liability as set
forth in Section 3.03 of this Agreement, the Merger Parties agree to maintain
the Merger Agreement in full force and effect, to take actions as shall be
necessary to facilitate the consummation of the Merger, to not take any action
that could impair impede or delay the consummation of the Merger or that could
adversely effect Purchaser's rights or any of the Merger Parties' obligations
under this Agreement and to use commercially reasonable efforts to enforce any
of the Merger Parties' rights under the Merger Agreement and/or to cause the
Tower Entities to cooperate with Purchaser, subject to the Merger Agreement,
regarding any matters related to Purchaser's acquisition of the Properties
and/or Purchaser's rights under this Agreement. Seller shall use good faith
efforts to promptly deliver to Purchaser a copy of any notice relating to the
Properties which Seller gives or receives pursuant to the Merger Agreement,
provided, however, that Seller shall have no liability to Purchaser for the
unintentional failure to do so.

     Section 14.04. Purchaser shall have the benefit of any consent and/or
approval rights (the "REPAIR CONSENT RIGHTS") granted to any of the Merger
Parties under the Merger Agreement with respect to any restoration, repairs
and/or capital improvements ("CONTRACT PERIOD REPAIRS"), including, without
limitation, Facade Work, to be performed at the Properties during the Contract
Period. If any of the Tower Entities notify Seller of any proposed Contract
Period Repairs, Seller shall promptly notify Purchaser thereof. Seller shall
consult with Purchaser prior to approving any Contract Period Repairs or
otherwise responding to the Tower Entities with respect thereto. Seller shall
reasonably cooperate with Purchaser and its architects, engineers and
contractors in evaluating any proposed Contract Period Repairs and shall
attempt to obtain such further information from the Tower Entities as such
parties may request. Seller shall deliver to the Tower Entities any reasonable
counterproposal prepared by Purchaser and/or its architects, engineers and
contractors in response to any proposed Contract Period Repairs. Purchaser
agrees, however, that the Merger Parties shall have no liability to Purchaser
should the Tower Entities perform any Contract Period Repairs without
permitting the Merger Parties to exercise any Repair Consent Rights or if the
Tower Entities reject any counter proposal prepared by Purchaser and/or its
architects, engineers and contractors. Nothing contained in this Section 14.04
shall be construed to limit Seller's obligation to deliver to the Disbursing
Agent the Facade Work Amount at Closing.

     Section 14.05. The provisions of this Section 14 shall survive the
Closing.

                            SECTION 15: BROKERAGE

     Section 15.01. Purchaser and the Seller represent and warrant to each
other that no broker or person was in any way instrumental or had any part in
bringing about this transaction. Purchaser agrees that, should any claim be
made for commissions by any broker or person arising by, through or on account
of any act of Purchaser or Purchaser's representatives, Purchaser shall
indemnify and hold the Seller harmless from and against any and all claim,
liability, cost or expense (including reasonable attorneys' fees) in
connection therewith. The Seller agrees that should any claim be made for
commissions by any broker or person arising by, through or on account of any
act of any Seller or such Seller's representatives, such Seller shall
indemnify and hold Purchaser harmless from and against any and all claim,
liability, cost or expense (including reasonable attorneys' fees) in
connection therewith. The provisions of this Section 15.01 shall survive the
Closing and/or the sooner termination of this Agreement, but the provisions
hereof shall not be deemed or construed as a covenant for the benefit of any
third party.

                 SECTION 16: CONDITIONS PRECEDENT TO CLOSING

     Section 16.01. Purchaser's obligations to close title under this
Agreement on the Closing Date shall be subject to the satisfaction of the
following conditions precedent on or prior to the Closing Date:

          (i) all of the Seller's representations and warranties made in this
     Agreement shall be true and correct in all material respects as of the
     date hereof and, with respect to the Closing Date Representations, as of
     the Closing Date, and Purchaser shall have received the benefit of the
     Consent Rights during the Contract Period and no monetary lien (other
     than a Recorded Mortgage subject to the provisions of Section 6 hereof)
     shall have been recorded (and remain outstanding) against any of the
     Properties during the Contract Period; provided, however, that Purchaser
     shall be obligated to consummate the Closing without any adjustment in
     the Purchaser Price if any Loss Events shall have occurred and the
     aggregate amount of the Losses resulting therefrom is equal to or less
     than $1,500,000. If any Loss Events shall have occurred and the aggregate
     amount of the Losses resulting therefrom exceeds $1,500,000, Purchaser
     shall be entitled to recover such Losses in excess of $1,500,000 from
     Seller at Closing by means of an adjustment or credit to the Purchase
     Price, or after Closing, as applicable, in accordance with any
     Purchaser's Loss Notice delivered in accordance with Section 10.14
     hereof; provided, however, that in no event shall Seller's liability
     hereunder, and Purchaser's credit on account thereof, exceed $2,000,000.
     If any Loss Events occur and the aggregate amount of the Losses exceeds
     $3,500,000, Purchaser shall have the right to terminate this Agreement
     and receive the return of the Deposit; provided, however, that Purchaser
     shall not be permitted to terminate this Agreement if Seller elects (it
     being acknowledged that Seller shall have the right but not the
     obligation to make such election) to grant an additional credit to
     Purchaser at Closing in the aggregate amount by which the Losses exceeds
     $3,500,000.00. In the event that there is a dispute as to whether a Loss
     Event has occurred, the Closing shall occur without adjustment regarding
     same, provided, however, that a portion of the Purchase Price equal to
     the disputed amount shall be held in escrow by the Escrow Agent pending
     resolution of the dispute. The provisions of this Section 16.01(i) shall
     not apply to a Loss incurred by Purchaser due to the failure of the
     Merger Parties to grant Purchaser Consent Rights with respect to a matter
     as to which Tower or Tower Realty had granted the Merger Parties the
     opportunity to exercise Consent Rights, it being understood that any such
     Loss shall be addressed as set forth in Section 14.01 hereof.

          (ii) the Seller shall have performed all material obligations and
     agreements undertaken by it herein to be performed at or prior to the
     Closing Date.

     (b) The Seller's obligations to close title under this Agreement on the
Closing Date shall be subject to the satisfaction of the following conditions
precedent on the Closing Date:

          (i) all of Purchaser's representations and warranties made in this
     Agreement shall be true and correct in all material respects as of the
     Closing Date as if they were made on that date; and

          (ii) Purchaser shall have performed all material obligations and
     agreements undertaken by it herein to be performed at or prior to the
     Closing Date.

                           SECTION 17: TRANSFER TAX

     Section 17.01. (a) Seller shall pay the applicable New York State and New
York City transfer tax (collectively, the "TRANSFER TAX") in connection with
the conveyance of the Properties to Purchaser. Seller hereby indemnifies and
holds Purchaser harmless from and against any loss, cost, claim, liability,
damage or expense (including reasonable attorneys' fees) which Purchaser may
incur or that may arise due to the failure of, or if it shall be finally
determined that, any additional Transfer Tax is due and payable including,
without limitation, any interest or penalty charges imposed by reason of the
untimely delivery to the appropriate recording officer of any payment of any
such Transfer Tax. Purchaser will reasonably cooperate with any structure for
the consummation of the transaction contemplated by this Agreement as proposed
by Seller so long as the implementation of such proposed structure would not
adversely affect Purchaser in any way. Notwithstanding anything herein to the
contrary, Seller shall use good faith efforts to cause the Tower Entities to
(i) execute and deliver a contract substantially in the form set forth in
Exhibit J attached hereto (the "CONTRACT OF Record"), (ii) execute and
deliver, prior to Closing, the Seller's Instruments and (iii) execute and
deliver an escrow agreement (the "CONVEYANCE ESCROW AGREEMENT") by and among
the Tower Entities and Seller, pursuant to which the Contract of Record and
the Seller's Instruments shall be held in escrow during the Contract Period
and released from escrow and delivered to Purchaser and/or Purchaser's
Affiliates in accordance with Section 21.01 hereof immediately prior to the
Merger. Notwithstanding the foregoing, in the event that Seller fails to cause
the Tower Entities to execute and deliver the Contract of Record, the Seller's
Instruments and the Conveyance Escrow Agreement on or before the tenth (10th)
Business Day after the date of this Agreement, Seller may on or before the
date ("SELLER'S OUTSIDE TERMINATION DATE") that is six (6) days after the
expiration of the foregoing ten (10) Business Day period, deliver to Purchaser
a notice (a "TOWER CONVEYANCE TERMINATION NOTICE") terminating this Agreement
in which case the Deposit shall be promptly returned to Purchaser and neither
party shall have any obligation to the other hereunder. If Seller has not
delivered to Purchaser a Tower Conveyance Termination Notice on or before the
Seller's Outside Termination Date, then Seller shall be deemed to have
irrevocably waived its right to terminate this Agreement on account of
Seller's inability to cause the Tower Entities to execute, deliver and perform
the Contract of Record, the Seller's Instruments and the Conveyance Escrow
Agreement. The failure by any of the Tower Entities and/or Seller to perform
their respective obligations under the Conveyance Escrow Agreement shall not
be, or be deemed to be, a condition to, or excuse, the performance by Seller
on or prior to the Closing Date of any of Seller's obligations under this
Agreement.

     (b) In the event of any inconsistency or conflict between the terms of
this Agreement and the Contract of Record, the terms of this Agreement shall
govern and control.

     (c) Notwithstanding anything contained herein or in Seller's Instruments
to the contrary, all surviving indemnities, representations and covenants of
Seller under this Agreement, the "seller" under the Contract of Record, and
the transferor under Seller's Instruments shall remain the obligations of the
applicable Merger Parties and/or shall be and shall be deemed to be, the
obligations of the applicable Merger Parties as successors in interest to the
Tower Entities.

     Section 17.02. The provisions of this Section 17 shall survive the
Closing.

                           SECTION 18: TOWER LEASE

     Section 18.01. Purchaser acknowledges that Seller shall terminate the
Tower Lease effective as of the 30th day after the Closing Date. Seller shall
not pay any lease termination fee and Purchaser shall not be entitled to any
adjustment to the Purchase Price in connection with such termination.

                             SECTION 19: NOTICES

     Section 19.01. All notices, requests and demands to be made hereunder to
the parties hereto shall be in writing (at the addresses set forth below) and
shall be given by any of the following means: (a) personal delivery
(including, without limitation, overnight delivery, courier or messenger
services); (b) telecopier (if printed confirmation of successful transmission
thereof is obtained from the sender's telecopier and same is confirmed
telephonically by the Sender), or (c) registered or certified, first-class
United States mail, postage prepaid, return receipt requested. Notice by a
party's counsel shall be deemed to be notice by such party. All notices to the
Seller shall be sent to the address set forth below. Such addresses may be
changed by notice to the other parties given in the same manner as provided
above. Any notice, demand or request sent (x) pursuant to subsection (a) shall
be deemed received upon such personal delivery, (y) pursuant to subsection (b)
shall be deemed received on the day it is dispatched by telecopier and (z)
pursuant to subsection (c) shall be deemed received five (5) days following
deposit in the mail.

                             SECTION 20: DEFAULT

     Section 20.01. Purchaser's Default. If Purchaser shall fail to close on
                    -------------------
the Closing Date and the Seller has performed or is ready, willing and able to
perform its obligations under the Merger Agreement and hereunder, then the
Seller shall have the right to treat this Agreement as having been breached by
Purchaser and the Seller's sole and exclusive remedy on account of such breach
shall be the right to terminate this Agreement by written notice to Purchaser
or Purchaser's attorney. Upon such termination (a) Purchaser shall forfeit all
rights and claims with respect to the Property pursuant to this Agreement and
to the Deposit; and (b) Escrow Agent shall remit the Deposit to the Seller.
The Seller and Purchaser hereby agree that payment of the Deposit to the
Seller shall be deemed to be fair and adequate, but not excessive, liquidated
damages (and not a penalty) based upon the following considerations which the
Seller and Purchaser agree would constitute damages to the Seller for any
default by Purchaser but which are impossible to quantify, to wit: (i) the
removal of the Property from the real estate market together with the
uncertainty of obtaining a new purchaser at the same or greater purchase
price; (ii) the expenses incurred by the Seller, including (but not by way of
limitation) attorneys' fees, taxes, mortgage interest, and other items
incidental to the maintenance of the Property until it is eventually sold; and
(iii) all other expenses incurred by the Seller as a result of Purchaser's
default.

In the event of such termination, Purchaser shall immediately return or
destroy its executed copy of this Agreement to the Seller for cancellation
together with all due diligence materials, reports and studies delivered to
Purchaser by the Seller (without Purchaser retaining copies thereof).

     Section 20.02. The Seller's Default. In the event the Seller is in
                    --------------------
default under this Agreement on the Closing Date, or at least ten (10)
Business Days prior to the Closing Date by reason of the Seller's failure or
refusal to comply with any terms of this Agreement for more than ten (10)
Business Days after receipt of written notice thereof has been given to the
Seller, then Purchaser's remedies shall be limited to the right to (a) the
immediate return of the Deposit and the cancellation of this Agreement, (b) if
the Merger has not occurred, bring an action to recover any sums due under
Section 3.03 hereof and (c) if the Merger has occurred, Purchaser may bring an
action to specifically enforce this Agreement and compel the Seller to perform
the terms and conditions of this Agreement and Purchaser shall have no other
rights or remedies against the Seller on account of a default.

                            SECTION 21: ASSIGNMENT

     Section 21.01. This Agreement and Purchaser's rights hereunder may not be
assigned by Purchaser without the prior written consent of the Seller except
that Purchaser may (i) assign it rights hereunder to any Affiliate and (ii)

transferee under any other Closing documents for the applicable Property

Purchaser prior to the Closing Date that title to the Properties has not

contained in this Agreement has not been satisfied or waived, Escrow Agent
shall with ten (10) Business Days, deliver a copy of said statement to the
Seller and return such Deposit to Purchaser on the tenth (10th) Business Day

by a statement executed by them both, provided if there is any dispute with
respect to the Deposit Escrow Agent may immediately and with notice to the
Seller and Purchaser, surrender said Deposit to a court of competent
jurisdiction for such disposition as may be directed by such court.

     Section 25.07. Upon delivery of the Deposit to either Purchaser, the

be answerable for the default or misconduct other than the willful misconduct
of its agents, attorneys or employees if they be selected with reasonable
care. The Escrow Agent is authorized to act upon any document believed by it
to be genuine and to be signed by the proper party or parties and will incur
no liability in so acting.

     Section 25.09. The Escrow Agent has executed this Agreement for the sole
purpose of agreeing to act as such in accordance with the terms of this
Agreement.

                   SECTION 26: CONFIDENTIALITY/PUBLICATION

     Section 26.01. Except as may be required by law or as may be necessary to
effectuate the contemplated transaction or except as set forth below, both the
Seller and Purchaser, individually and on behalf of their representatives,
including, without limitation, Purchaser's financial advisors, attorneys,
accountants, actual and prospective lenders, tenants, contractors, agents,
employees and actual and prospective investors (but, with respect to
Purchaser, expressly excluding prospective purchasers), agree that prior to
Closing they and their respective representatives shall hold both the terms
and conditions of this Agreement and its existence as confidential information
and will not disclose such terms, conditions or existence or the fact that the
negotiations are taking place, to any third party without the other's consent.
On or after (but in no event before) the earlier to occur of (x) the date on
which Tower agrees in writing to enter into the Contract of Record and (y) the
Seller's Outside Termination Date, provided that Seller has not delivered to
Purchaser a Tower Conveyance Termination Notice on or prior to such date,
Seller and/or Purchaser may announce the transaction contemplated herein in a
press release after first submitting the proposed press release to the other
party for its review and approval which shall not be unreasonably withheld or
delayed. It shall be deemed reasonable for any party hereto to object to any
press release if same, in the reasonable opinion of such party, casts such
party or the transaction contemplated hereunder in an unfavorable light.

                    SECTION 27: EMPLOYEES/UNION AGREEMENT

     Section 27.01. Purchaser acknowledges that the Tower Entities are parties
to the Union Agreements with respect to certain employees located at the
Properties. At Closing, (i) Seller shall not assign any of its rights under
the Union Agreements to Purchaser and (ii) Purchaser shall not assume any of
Seller's obligations under the Union Agreements. As a condition of Seller
agreeing to the foregoing, Purchaser shall and does hereby agree to indemnify,
defend and hold Seller (and the Tower Entities, if applicable) free and
harmless from and against any and all liability, claims, actions, damages,
judgments, penalties, costs and expenses, including reasonable attorneys'
fees, accruing under any such Union Agreements to the extent such liabilities,
claims, actions, damages, judgments, penalties, costs and expenses are
directly related to actions taken by Purchaser or the fact that Purchaser has
not assumed the Union Agreements. The provisions of this Section 27 shall
survive Closing.

                         SECTION 28: TAX PROCEEDINGS

     Section 28.01. The Merger Parties agree, to the extent any of the Merger
Parties have such rights under the Merger Agreement, that prior to the Closing
Date none of them shall commence or permit to be commenced any tax
proceeding(s) for the reduction of the assessed valuation of any of the
Properties as it relates to any portion of the fiscal tax year in which the
Closing occurs, or any fiscal tax year prior thereto, without the consent of
Purchaser, which consent shall not be unreasonably withheld. To the extent any
of the Merger Parties have such rights under the Merger Agreement, the Merger
Parties shall not, and shall not permit any other parties, to withdraw, settle
or otherwise compromise any such proceeding as it relates to any portion of
the fiscal tax year in which the Closing occurs without the prior written
consent of Purchaser, which consent shall not be unreasonably withheld. Real
estate tax refunds or credits received by Seller that are attributable to the
fiscal tax year in which the Closing occurs shall be apportioned between
Seller and Purchaser less any reasonable expenses incurred by Seller in
connection with the prosecution of such proceeding. In the event any such
proceeding shall affect a fiscal tax year falling entirely during Purchaser's
period of ownership, Seller shall, at Purchaser's election, at the Closing,
assign all of its right, title and interest in such proceeding to Purchaser
pursuant to an assignment in form reasonably acceptable to Purchaser. If
Purchaser does not elect to accept such assignment, Seller may withdraw such
proceeding. Real estate tax refunds or credits received by Purchaser
post-Closing directly from the applicable municipality that are attributable
to the fiscal tax year in which the Closing occurs shall be apportioned
between Seller and Purchaser less any reasonable expenses incurred by
Purchaser in connection with the prosecution of the applicable tax proceeding.
The provisions of this Section 28 shall survive Closing.

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

     Section 1445 of the Internal Revenue Code provides that a transferee of a
U.S. real property interest must withhold tax if the transferor is a foreign
person. To inform the transferee that withholding of tax is not required upon
the disposition of a U.S. real property interest by             ("Seller"),
                                                    -----------
Seller hereby certifies the following:

1.   Seller 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);

2.   Seller's U.S. employer identification number is (                 ) and
                                                      -----------------

3. Seller's principal place of business is (                               ).
                                            -------------------------------

     Seller 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.

     Under penalties of perjury I declare that I have examined this
certification and to the best of my knowledge and belief it is true, correct
and complete, and I further declare that I have authority to sign this
document on behalf of Seller.

 SL Green's Portfolio Totals 23 Properties and Nearly 8.0 Million Square Feet
                       Of Prime Manhattan Office Space

NEW YORK, NY, JUNE 2, 1999 - SL Green Realty Corp. (NYSE:SLG) ("SL Green")
announced today that it closed on May 24, 1999 its previously announced
agreement to purchase the fee interest in four New York city office properties
from Reckson Associates Realty Corp. (NYSE:RA) ("Reckson"). The properties
total 675,000 square feet and were acquired for $84.5 million in cash
($125/square foot).

The properties previously owned by Tower Realty Trust, Inc. ("Tower") were
among those included in the now completed merger agreement among Reckson,
Metropolitan Partners LLC ("Metropolitan") and Tower. The properties include
an entire blockfront in midtown Manhattan between 40th and 41st Streets along
Madison Avenue (286, 290 and 292 Madison Avenue), and 90 Broad Street in
downtown Manhattan. The transaction increases SL Green's ownership of office
buildings in Manhattan to 23, totaling approximately 8.0 million square feet.

Financing of the final transaction was arranged for SL Green through
Prudential Securities and Deutsche Bank Securities. Prudential provided
secured bridge financings in the amount of $51.7 million, for a term of one
year. Deutsche Bank provided a $65 million floating rate financing on the
Graybar Building, having a term of two years. Excess funds will be used to
repay a part of the outstanding balance of the Company's unsecured line of
credit.

SL Green Corp. is a fully integrated, self-administered and self-managed real
estate investment trust ("REIT") which primarily owns, manages, leases,
acquires and repositions Class B office properties in Manhattan.
