         WHEREAS, the Company proposes to raise up to $600,000,000 through the
sale of shares of common stock of the Company (the "Shares") as described in a
Registration Statement on Form S-11 (File No. 333-xxxxx), filed with the
Securities and Exchange Commission and any registration statement relating
thereto filed under Rule 462(b) of the Securities Act of 1933 as amended (the
"Registration Statement"); and

         WHEREAS, the Company desires to retain Carey Financial and Carey
Financial desires to undertake to coordinate the performance of certain
wholesaling services for the Company pursuant to this Agreement on the terms and
subject to the conditions hereinafter set forth and subject to the limitations,
if any, set forth in the final Prospectus which will be included in the
Registration Statement.

         NOW THEREFORE, in consideration of the mutual promises herein made and
for other good and valuable consideration, and intending to be legally bound
hereby, the parties hereto agree as follows:

         1. The Company hereby retains Carey Financial to provide the following
services for the Company:

         (a) Carey Financial shall develop and prepare sales literature to be
         used by the Company in the offer and sale of the Shares (the
         "Offering"), which sales literature shall comply with the Securities
         Act of 1933, as amended ("the "Securities Act"), and the regulations
         thereunder, the Rules of Fair Practice of the National Association of
         Securities Dealers, Inc. (the "RFP") and the "blue sky" laws of any
         jurisdiction in which such material is used ("Blue Sky Law"). The sales
         literature may include, but not be limited to, a slide presentation, a
         property acquisition report, a brochure and seminar invitations for
         presentation and distribution to the public and an audio program, a
         video program and a brochure for presentation and distribution to
         broker-dealers.

         (b) Carey Financial shall assist broker-dealers and registered
         investment advisors participating in the Offering by coordinating
         broker-dealer and registered investment advisor seminars, informational
         meetings, preparing and distributing brochures and other sales
         literature designed for broker-dealers and registered investment
         advisors and providing information and answering any questions with
         regard to the Offering.

         Offering as selected dealers.

         2. In consideration for providing the above services, Carey Financial
shall receive reimbursement for identified expenses incurred in connection with
its wholesaling activities described in Section 1 above, including but not
limited to: (a) travel and entertainment expenses; (b) the cost of compensation
paid to employees of Carey Financial in connection with wholesaling activities;
(c) expenses incurred in coordinating broker-dealer and registered investment
advisor seminars and meetings; and (d) wholesaling fees of one half percent and
wholesaling expense reimbursements paid to it or its Affiliates or other
entities.

         3. The Company shall, at the direction of Carey Financial, reimburse
directly all other entities for marketing and wholesaling expenses of the type
described in clauses (a), (b) and (c) of Section 2 hereof incurred directly by
those entities at the request of Carey Financial.

         4. Carey Financial shall adopt procedures which it, in its sole
discretion, deems adequate to monitor compliance with the limitation in Rule
2710 of the Conduct Rules of the NASD thereto on aggregate compensation to it
and all broker-dealers participating in the Offering. In no event will the
amounts paid hereunder, when combined with all other underwriting compensation
paid in connection with the offering, exceed 10% of Gross Offering Proceeds plus
0.5% for bona fide due diligence expenses.

         5. The Company hereby represents and warrants to Carey Financial that
the representations and warranties of it set forth in Section 2 of the Sales
Agency Agreement, dated the date hereof, between the Company and Carey
Financial, as Sales Agent (the "Sales Agency Agreement"), are true and correct
in all respects, and that such representations and warranties are hereby
incorporated by reference herein (together with all related definitions and
cross-references) as if set forth in full herein.

         6. The Company hereby covenants to Carey Financial that it will honor
and perform each of the covenants made by it in Section 4 of the Sales Agency
Agreement, and agrees that such covenants are incorporated by reference herein
(together with all related definitions and cross-references) as if set forth in
full herein.

         7. The term of this Agreement shall commence on the date hereof and
shall continue until such time as the Offering is completed. Notwithstanding the
foregoing, this Agreement may be terminated without the payment of any penalty
by either party upon not less than 60 days' notice in writing to the other
party, except for the payment to Carey Financial of unreimbursed expenses
incurred by it prior to the date of termination.

         8. Carey Financial may assign any of its rights or delegate the
performance of any of its obligations hereunder to its Affiliates or any other
entity, provided, however, that no such delegation shall relieve Carey Financial
of its obligations hereunder.

         9. The parties hereto agree that they have not created a joint venture
or partnership relationship between them, that Carey Financial shall be deemed
to be an independent contractor and not for any purpose to be an employee of the
Company.
