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

Dear Mike:

         I am very pleased to make the following offer to you with regard to
employment at Acadia Realty Trust as Senior Vice President and Chief Financial
Officer. You shall report directly to me as President of the Company.

         Pursuant to our conversation, the following is our offer to you:

1. Base Salary:               $200,000 per annum less the car allowance
                              described below.

2. Bonus:                     For your first year of employment, you are
                              guaranteed a minimum cash bonus of $75,000,
                              prorated for a partial year and payable after
                              December 31, 2003. All future bonuses shall be
                              discretionary and range from 25% to 50% of base
                              salary.

3. Longterm Compensation:     You shall participate in a contemplated long term
                              compensation plan being proposed to the
                              shareholders of Acadia. I anticipate that the
                              value of your participation in 2003 shall be
                              approximately $75,000, as prorated. In the event
                              that the plan is rejected by Acadia's
                              shareholders, adjustments will be made in the cash
                              portion of your compensation.

4. Duties:                    You will be responsible for all financial
                              reporting and activities of the Company, including
                              preparation and delivery of reports to the Board
                              of Trustees. As such, all accounting/financial
                              personnel shall report to you.

5. Location:                  We expect to relocate our offices in the near
                              future to an office park in Westchester County,
                              most likely in the White Plains/Harrison area.


6. Car Allowance:         You will be given up to $800 a month for your car
                          allowance (inclusive of loan or lease payments,
                          insurance premiums and repairs). Gas and tolls for
                          business related trips will be reimbursed
                          separately.

7. Severance:             Your employment may be terminated at any time by
                          you or Acadia, subject to the provisions of this
                          paragraph. You shall receive a severance package
                          comparable to the package established for other
                          senior executives of the Company (with the
                          exception of certain change of control
                          provisions). The agreement shall provide that you
                          shall receive six months' salary and car allowance
                          if you are terminated without Cause (defined as
                          deliberate misrepresentation, willful misconduct,
                          willful failure to perform your duties or
                          conviction for felony) during the first year of
                          employment and a full year's salary and car
                          allowance after the first year of employment. If
                          you resign or are terminated for Cause, no
                          additional compensation or severance shall be due
                          to you. Attached is a draft of the Severance
                          Agreement.

8. Vacation:              You shall be entitled to up to four weeks of
                          vacation annually.

9. Start Date:            We have agreed that you shall commence working at
                          Acadia on or before March 15, 2003.

         We look forward to having you join our team at Acadia. If this offer is
acceptable, please acknowledge by faxing back to me an executed copy of this
letter.

                                                  Very truly yours,
