                  2. Creating a marketing program which may include newspapers,
         magazine or journal advertising, flyer solicitation and placement of
         signs, as appropriate. Preparing and disseminating all such marketing

         sole cost and expense of Owner.

                  3. Communicating with parties who have expressed an interest
         in the Assets and responding and providing information to, negotiating
         with, and soliciting offers from, prospective purchasers, including
         landlords, and making recommendations to Owner as to the advisability
         of accepting particular offers and settlements.

                  4. Arranging for physical inspections of the Assets by
         prospective purchasers.

                  5. When requested, meeting periodically with Owner, their

         disposition of the Assets.

                  6. If required, appearing in Court during the term of this
         retention, to testify or to consult with Owners in connection with the
         marketing or disposition of the Assets.

II.      BASIS OF RETENTION AND COMPENSATION

                  Vornado will actively and diligently discharge its obligations
under this Agreement. Vornado shall be retained by Owner for the purpose of
performing the services outlined above, upon the following terms and conditions:

         A. Exclusive Right:

                  1. Vornado shall have the sole and exclusive authority to
         offer each Asset for disposition and the "exclusive right to sell" and
         "exclusive right to lease" each Asset. All communications and inquiries
         regarding any Asset, whether directed to Owner (including but not
         limited to their officers, agents and employees), or Owners' counsel,
         accountants, or other professionals, shall be redirected to Vornado.

                  2. Owner shall retain the complete discretion and authority to
         accept or reject any offer. Owner shall not have any liability
         whatsoever to Vornado for exercising its discretion with respect to the
         acceptance or rejection of any offer.

         B. Term: The term of Vornado's retention shall be from the date hereof
and shall continue for one (1) year hereafter, and, thereafter, shall
automatically renew on a year-to-year basis, terminable by either party at the
end of each year on not less than sixty (60) days' prior notice.

         C. Fee: Vornado's fee shall be computed and paid as follows:

                  1. (a) When Owner disposes of an Asset, whether individually
         or as part of a package or as part of the disposition of Owner's
         business or a portion thereof, or as part of a plan or reorganization,
         by sale, assignment, lease, sublet or otherwise to a third party, or by
         assignment of a leasehold to the landlord or by termination of a
         leasehold for which Owner receives consideration; or, if in lieu of a
         disposition of the Assets, one or more third parties acquires control
         of Owner by merger, outright purchase, or otherwise in one or multiple
         transactions (an "Acquisition Transaction"); then Owner shall pay an
         amount equal to three percent (3%) of the Gross Proceeds from the
         transaction pertaining to such Asset (or in the case of an Acquisition
         Transaction, the Gross Proceeds in respect thereof) except in the event
         of a lease or sublease, in which event Owner shall pay an amount equal
         to:

                  (i) three (3%) percent of the total base rent Gross Proceeds
         payable during the first ten (10) years of the term, plus

                  (ii) two (2%) percent of the total base rent Gross Proceeds
         payable during the eleventh (11th) through the twentieth (20th) years
         of the term, plus

                  (iii) one (1%) percent of the total base rent Gross Proceeds
         payable during the balance of the term, but in no event to exceed the
         thirtieth (30) year;


                                      -2-

         (In the event of a month-to-month tenancy, the fee shall be 50% of the
         first month's base rental, payable in four equal monthly installments
         of 25% of the total fee, but only for so long as such tenancy shall
         continue. Additional fees shall become earned and payable (i) upon a
         tenant's exercise of Option(s) or Right(s) of First Refusal, to Renew,
         Extend Lease or Occupy Additional Space, as discussed below or (ii)
         upon a month-to-month tenant entering into a new lease or sublease of
         an Asset).

                  (b) Vornado's fee will be paid in full simultaneously with the
         closing, sale, assignment or other consummation of the transaction.
         Notwithstanding the immediately preceding sentence, Vornado's fee will
         be payable in an amount not to exceed $2,500,000 in any calendar year
         or part thereof (or such lesser amount as may be due Vornado hereunder)
         in equal monthly installments until the present value (applying a
         discount rate of 9% per annum) of such installments paid to Vornado
         equals the fee due hereunder that would have been paid had it been paid
         simultaneously with the closing, assignment or other consummation of
         the applicable transaction; provided, however, that (i) fees payable in
         respect of a sale, assignment or Acquisition Transaction are paid first
         and (ii) Vornado shall not be entitled to receive any fees in respect
         of a lease or sublease to the extent the tenant is in default of its
         payment obligations thereunder, except as a result of a default by the
         Owner or a termination by Owner of the lease or sublease (other than a
         termination by the Owner resulting from the tenant's monetary default).
         Any payment made to Vornado pursuant to the immediately preceding
         sentence will be credited against the fees to which Vornado shall be
         entitled, provided that such amounts shall have been earned hereunder.
         If Vornado's fees shall not equal at least at the amount of
         reimbursements paid to Vornado under this paragraph (b), then Vornado
         will remit the excess of reimbursement amounts over fees to Owner. Any
         fees that become payable with respect to the leases listed on Schedule
         B attached hereto shall be payable by Owner under this Agreement in
         accordance with the above provisions.

                  (c) In the event that the Owner leases or subleases an Asset
         and the transferee, or any agent, officer, employee, or shareholder of
         the transferee, acquires fee-simple title to such property within five
         years, Vornado shall then receive three percent (3%) of the Gross
         Proceeds payable in the same manner as described above; provided,
         however, that there shall be a credit against such subsequent fee in
         the amount of fees, previously paid relating to that portion of the
         lease or sublease term which is cancelled by reason of such sale. In no
         event shall such credit exceed the amount of the latter fee.

                  (d) If an Asset for which a fee is payable hereunder contains
         (i) an option(s) or right(s) of first refusal to renew or extend, and a
         lease term(s) is renewed or extended whether strictly in accordance
         with the terms of such option(s) or right(s) or otherwise and/or (ii)
         an option(s) or right(s) of first refusal to expand, and a tenant
         occupies additional space whether strictly in accordance with the terms
         of such option(s) or right(s) or otherwise, with respect to space owned
         by, or leased to, the Owner, then Owner shall pay a leasing fee in
         accordance with the provisions of this agreement on the additional base
         rental to be paid, except that in the case of renewal or extension, the
         fee shall be calculated at the rate applicable hereunder as if such
         renewal or extension period were included in the initial term of the
         lease, and in the case of the tenant occupying additional space, the
         fee shall be calculated at the rate applicable hereunder as if such


                             -3-

         expansion were a new lease. Such fee shall be earned and payable at the
         time the extended term commences or the additional space is occupied,
         as applicable.

                  (e) If a lease for which a fee is payable hereunder contains,
         as a primary component of the consideration to be paid by a tenant for
         the rent thereunder, a percentage rent clause, Owner shall pay a fee on
         the percentage rent payable by the tenant at the commission rate
         applicable to the period of the lease term for which the percentage
         rent is payable. Subject to paragraph II.C.1 of this Retention
         Agreement, the fee shall be payable within fifteen days after the
         tenant's final payment and accounting of percentage rent for the
         preceding lease year.

                  (f) In any transaction whereby Owner leases or subleases an
         Asset, Vornado shall have the right to receive all formal notifications
         required pursuant to the lease to the extent that any such notice may
         affect the rights of Vornado hereunder or the timing or payment of any
         fees due hereunder. In furtherance of such rights, Owner shall insert
         within the terms of such lease or sublease a separate paragraph that
         states Vornado's right to notice, right to a fee as described in the
         above subparagraphs and Vornado's address and phone number shall be
         included in the "notice" provision of such lease or sublease.

                  (g) In the event that a party other than Vornado is a
         procuring broker who is entitled to a fee, the fees payable shall be
         increased from three percent (3%) to four percent (4%) and, in the
         event of a lease or sublease, the three-two-one (3-2-1) schedule set
         forth in paragraphs II.C.1(a)(i), (ii) and (iii) above shall be
         increased to four-three-two (4-3-2) and Vornado shall pay the fee of
         the procuring broker. For any given transaction, Owner shall be
         responsible for the payment of only one fee in the amounts set forth
         herein.

                  (h) The term "base rent" means the base rent set forth in any
         lease and shall not include any additional rent, whether for utilities,
         taxes or otherwise, and which is ordinarily not a component of base
         rent, which may be payable under such lease.

                  2. The term "Gross Proceeds" as used herein shall include the
         sum of:

                  (a) the total cash consideration transferred to or for the
         benefit of Owner; plus

                  (b) the balance, if any, of any outstanding mortgage(s) to be
         transferred to or assumed by the transferee; plus

                  (c) any deferred payment obligation granted by Owner to the
         transferee; plus

                  (d) the value of any waiver, relinquishment, transfer or
         assignment of any lien, and/or the value of any deposit, claim, or
         rights through which consideration is given whereby Owner shall receive
         compensation or a credit for payment; plus

                  (e) in the case of an Acquisition Transaction, "Gross
         Proceeds" shall be the value of the consideration to be received by
         Owner, its creditors or its stockholders.


                                      -4-

                  3. Except as provided in paragraph II.C.1.(b), the computation
         of Gross Proceeds as well as the computation of fees hereunder shall
         not be affected by the costs of advertising, Owners' legal fees,
         break-up fees, Vornado's expenses nor any closing costs and/or
         adjustments, including but not limited to adjustments and/or payments
         of whatever kind to landlords, lienholders, secured parties, mortgages
         or offerors.

         D. Expenses and Disbursements:

                  1. Vornado will not be responsible for any legal expenses
         incurred by Owner in connection with its retention of Vornado, the
         disposition of the Assets and the preparation of legal motions and
         documents, including but not limited to the costs of preparing
         contracts and assignments as well as the costs of attending hearings
         and closing, among other things.

                  2. All advertising, marketing, and other third party expenses
         shall be borne by Owner. Vornado will prepare a marketing budget and,
         upon the retention of Vornado and the approval of the budget by Owner,
         Owner agrees to pay all such costs and expenses to Vornado immediately
         upon the proper presentation of invoices. Vornado shall be under no
         obligation to incur such expenses until such time as Vornado receives
         funds from Owner.

                  3. In the event Owner fails or is unable to pay the expenses
         as above described or such additional expenses as Owner may approve,
         and Vornado shall have given Owner prior written notice of its
         intention to resign and the reason therefor and Owner shall not have
         cured such failure within fifteen (15) days after receipt of such
         notice by Owner, Vornado shall have the right to so resign,
         individually, and pursue any claims that Vornado might have.

         E. Survival:

                  1. In the event Owner and any third party should enter into an
         agreement providing for the sale, assignment, lease or other
         disposition of an Asset, or providing for an Acquisition Transaction,
         before the expiration of this Retention Agreement, and the closing does
         not occur until after such expiration, then Vornado shall be entitled
         to a fee in accordance with the terms of this Retention Agreement. If
         Owner, after the expiration of this Retention Agreement, arranges for
         the sale, assignment, lease or other disposition of an Asset, or
         arranges for an Acquisition Transaction of an Asset to a third party
         where Vornado substantially contributed to the consummation of such
         sale, assignment, lease or other disposition of an Asset or Acquisition
         Transaction during the term of this Retention Agreement, or with whom
         Owner signed a letter of intent for such transaction during the term of
         this Retention Agreement and, in any such event, the contract signing
         or closing takes place within six (6) months after such expiration,
         then Vornado shall be entitled to a fee in accordance with the terms of
         this Retention Agreement. Within thirty (30) days after the termination
         or expiration of this Retention Agreement, Vornado will furnish Owner
         with a list of the parties with whom a transaction with respect to the
         Assets would, in Vornado's view, give rise to a claim for a fee by
         Vornado under this paragraph. The


                                      -5-

         receipt of such a list by Owner shall not be construed as consent by
         Owner to the names contained thereon.

                  2. Vornado's rights to fees from the future potential exercise
         by a tenant of option(s) or right(s) of first refusal, to renew, to
         extend the lease, and/or to occupy additional space, shall survive this
         Retention Agreement.

         F. Owner Responsibilities: Owner shall inform Vornado in writing
immediately after Owner shall become aware, after the execution and delivery of
this Retention Agreement, of any known or suspected risk of environmental hazard
or contamination or of the receipt by Owner of a citation for the violation of
any federal, state or local environmental law or regulation. Owner shall have
the continuing obligation to advise Vornado in writing as soon as it becomes
aware of any inaccuracy, inconsistency, incompleteness or change of
circumstances and to correct any environmental report with respect to the
Assets. Owner will use its best efforts to deliver to Vornado all environmental
reports in its possession. Additionally, Owner will provide, promptly upon
receipt thereof, a copy of any environmental reports prepared after the date
hereof to Vornado and will authorize Vornado to disseminate such report to
prospects. Vornado shall be the only entity entitled to rely on the covenants
contained in this paragraph. Any damages for a breach or violation of the
covenants contained in this paragraph shall be limited to Vornado's
out-of-pocket expenses incurred in reliance on the covenants contained in this
paragraph less any fees earned from the transaction related to the expenditure
of such expenses.

         G. General Provisions:

                  1. Vornado hereby indemnifies Owner for all costs, expenses,
         damages, losses, obligations and liabilities that may arise from the
         claim by a third party with whom Vornado dealt in connection with the
         disposition of any Asset that such third party is entitled to a fee,
         broker's commission or any other payment arising from the disposition
         of such Asset. The indemnity provided for in this paragraph shall be
         limited to the fees earned by Vornado from the disposition of the Asset
         or Assets giving rise to the claim.

                  2. The parties hereto, on behalf of themselves and their
         respective officers, directors, agents and employees, agree to deal
         with each other fairly and in good faith so as to allow each party to
         perform its services and obligations and to receive the anticipated
         benefits of this Retention Agreement. No party shall interfere, prevent
         or prohibit another party from carrying out its duties and obligations
         under this Retention Agreement.

                  3. By executing or otherwise accepting this Retention
         Agreement, the parties hereto each acknowledge and represent that they
         are represented by and have consulted with legal counsel with respect
         to the terms and conditions contained herein.

                  4. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ALL
         RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM
         ARISING OUT OF OR RELATING TO THIS RETENTION AGREEMENT.

                  5. This Retention Agreement may be executed in original
         counterparts.


                                      -6-

                  6. This Retention Agreement shall be governed by, and
         construed in accordance with, the laws of the State of New York.
