Re: Separation Agreement

Dear Gary:

As we discussed with respect to your departure from Heritage Property Investment Trust, Inc., its affiliates and subsidiaries (“Heritage”), your employment with Heritage will end effective September 1, 2003 (the “Separation Date”). The purpose of this letter is to resolve all outstanding issues and set forth our agreement with respect to your separation (the “Agreement”). This Agreement is intended to supersede and replace in all respects the Severance Agreement, between Heritage and you, dated as of August 28, 2002 (the “Severance Agreement”). Any defined terms used herein that are not defined herein are to have the meanings given to those terms in the Severance Agreement.

Under this Agreement, you and Heritage agree as follows:

1. Termination of Employment. Heritage will treat your separation as a termination of employment without “Cause”. Except as otherwise provided in this Agreement, no compensation or benefits, other than those listed below, will accrue or be owing in any respect of any period after the Separation Date, and no other liability of either Heritage or you, of any kind, will accrue on account of the termination of your employment.

2. Salary and Bonus Payments. In connection with your separation of employment, you will be entitled to the following payments:

(a) Accrued Salary. Heritage will continue to pay your salary through the Separation Date, consistent with Heritage’s regular payroll procedures. Additionally, immediately following your Separation Date, Heritage will pay you all your unused, accrued vacation time in the amount of $25,385, equivalent of 4 weeks of vacation. All payments under this section will be

based on your 2003 base rate of pay (i.e., $330,000) less the deductions required by law.

(b) Additional Salary Payment. Heritage agrees to pay you an additional amount of $495,000, which is the equivalent of 18 months of your 2003 base rate of pay (i.e., $330,000), less the deductions required by law.

(c) Bonus Payment. Heritage agrees to pay you a bonus payment of $392,000, which is the equivalent of 21 months of your average annual bonus during the past three fiscal years, less the deductions required by law.

(d) Method of Payment. One half of the total payments provided for in Section 2 (b) – (c) hereof, as applicable, i.e. $443,500, shall be made as salary continuation, net of tax withholding, payable in equal installments at Heritage’s regular payroll periods and in accordance with its regular payroll practices, continuing for the 18-month period following the Separation Date. The remaining $443,500, net of tax withholding, shall be made in a cash lump-sum payment upon the Separation Date.

3. Other Benefits.

(a) Insurance Benefits. Heritage shall continue to provide you with your current Health ($1,300 per month), Dental ($115 per month) and Group Life Insurance ($50 per month) benefits for 18 months following the Separation Date, to the extent available under Heritage current insurance policies. To the extent coverage is not available under current policies, Heritage will reimburse you for the reasonable costs (as set forth above) of such benefits directly. Heritage shall continue to provide you with Short-term and Long-term Disability Insurance ($115 per month) benefits through the Separation Date. To the extent you become entitled to comparable coverage under the insurance plan of another employer, including a partnership, following the Separation Date, no benefit provided under this provision will be provided to you.

(b) SERP. As of the Separation Date, you will cease to accrue any additional benefit under Heritage’s Supplemental Executive Retirement Plan (“SERP”). You will, however, be eligible to receive benefits under the SERP following your 65th birthday, in accordance with the terms and conditions of the SERP. Alternatively, within 30 days of the Separation Date, you may elect to receive payment of your vested SERP benefits, commencing at any time, in accordance with the terms and conditions of the SERP. For your information, if you choose to make such an election before your 65^th birthday, the SERP payment will be actuarially reduced in

accordance with the SERP. A copy of the SERP, which details options for distributions, is attached hereto as Exhibit A.

(c) 401k Plan. Heritage will provide you with the maximum allowable contribution with respect to your Heritage 401(k) account for 2003. Following the Separation Date, you will cease accruing amounts in your 401(k) as you will no longer be employed by Heritage. Following the Separation Date, you will be entitled to transfer your account balance or take a distribution according to Plan rules and procedures.

(d) Automobile. Heritage will allow you to retain the automobile that Heritage has leased on your behalf through the expiration of the lease on June 21, 2003, and for an additional period through the Separation Date. Heritage will take the steps necessary to extend the lease through the Separation Date. On or before the Separation Date, you must return the car subject to the lease to Heritage. For the lease period ending on the Separation Date, Heritage will continue paying one hundred percent (100%) of the lease and insurance payments, as well as the appropriate excise tax. Immediately following the Separation Date, Heritage will pay you the equivalent of $1,000 per month for 18 months, less the deductions required by law, so that you may purchase or lease an equivalent automobile and appropriate insurance. The payments will be made at Heritage’s regular payroll periods and in accordance with its regular payroll practices.

(e) Outplacement Services. In lieu of providing you with professional outplacement services, immediately following the effective date of this Agreement, which is the day immediately following the expiration of the seven (7) day revocation period referred to in Section 24 hereof (“the Effective Date”), Heritage will pay you $5,000, less the deductions required by law, in a cash lump-sum payment.

(f) Expense Reimbursement. Heritage will reimburse you for any unpaid, reasonable business expenses incurred by you up to the date of this Agreement upon delivery by you to Heritage of appropriate back-up documentation.

4. Equity Compensation. With respect to your shares of common stock and stock options, the following provisions will apply:

(a) Vested Stock Options. As of the date of this Agreement, you hold vested options to purchase 220,000 shares of Heritage common stock under Heritage’s Amended and Restated 2000 Equity Incentive Plan. All of these options are currently exercisable by you at an exercise price of $25.00 per share. The Equity Incentive Plan provides that these options

will continue to be exercisable by you for ninety (90) days following the Effective Date of this Agreement; provided, however, that, as a result of the fact that you are in possession of material, non-public information about Heritage as of the date of this Agreement, you are not currently permitted under Heritage’s Insider Trading Policy to engage in transactions in Heritage common stock while you are in possession of such information. Therefore, these options will continue to be exercisable by you for ninety (90) days following the date on which Heritage notifies you in writing that you are no longer prohibited under Heritage’s Insider Trading Policy from engaging in transactions in Heritage common stock. Heritage is currently pursuing the implementation for all Heritage employees of a so-called “cashless” exercise method to permit you to exercise these options and the options referred to in (b) below by the payment of the exercise price either through the surrender of other stock or options or with the cash proceeds from the sale of the shares acquired upon exercise of the options. We anticipate that this plan will be implemented and will be available to optionholders shortly. As outlined above, once you are able to sell shares on the open market (i.e., once you are no longer in possession of material, non-public information about Heritage), you will be able to participate in this program. To the extent that you incur any federal or state taxes in connection with the exercise of these options and/or the sale of any shares in connection with the exercise, you will be required to pay or Heritage will withhold those taxes.

(b) Unvested Stock Options. As of the date of this Agreement, you also hold unvested options to purchase 130,000 shares of Heritage common stock under the Equity Incentive Plan, of which 50,000 options are exercisable at an exercise price of $25.00 per share, and 80,000 options are exercisable at an exercise price of $24.36 per share. These options are not yet exercisable. However, Heritage agrees to accelerate the vesting of all of these options so that they will be immediately exercisable from and after the Effective Date of this Agreement and for the same period of time as the options referred to in (a) above. As with your vested options, Heritage anticipates that a cashless exercise method of exercising these options will be available to you. To the extent that you incur any federal or state taxes in connection with the acceleration of these unvested options, the exercise of these options and/or the sale of any shares in connection with the exercise, you will be required to pay or Heritage will withhold those taxes.

(c) Unrestricted Shares of Common Stock. Heritage’s records indicate that as of the date of this Agreement, you own 62,479 shares of common stock free and clear of any restriction or risk of forfeiture. You will be entitled to retain these shares of common stock following the Separation Date.

(d) 2002 Performance Shares. In March 2003, you were issued 18,000 shares of common stock under the Equity Incentive Plan relating to your 2002 performance. These shares are subject to transfer restrictions and risk of forfeiture, which will not terminate completely until January 2006. However, Heritage agrees to accelerate the termination of these restrictions to the Separation Date so that as of the Separation Date, you will own these shares free and clear of any restrictions. To the extent that you incur any federal or state taxes in connection with the early termination of these restrictions, you will be required to pay or Heritage will withhold those taxes. You agree that you are not entitled to any performance shares for 2003.

(e) Special Stock Awards. In July 2002, the Heritage Board of Directors approved the issuance to you of 20,000 restricted shares of common stock as part of an overall award to members of senior management of Heritage. In addition, the Board of Directors also reserved an additional 80,000 restricted shares of common stock for possible future issuance to you over four years, subject to your continued employment and other terms and conditions. The restrictions on the first 20,000 share award have terminated and these shares are included in your total described in (c) above. In March 2003, you were awarded the second installment of 20,000 restricted shares. The restrictions on these shares will not terminate until March 2004. However, Heritage agrees to accelerate the termination of these restrictions to the Separation Date so that as of the Separation Date, you will own these shares free and clear of any restrictions. To the extent that you incur any federal or state taxes in connection with the early termination of these restrictions, you will be required to pay those taxes. You agree that you are not entitled to any further installments of these special stock awards.

(f) Schedules. Schedules of the above stock and options with their respective vesting dates are attached hereto as Exhibit B.

5. Resignation as an Officer and Director and Press Release. Effective immediately by your signing this Agreement, you resign from your positions as an officer and/or director of Heritage and its subsidiaries. Heritage will issue a press release concerning your departure in the form attached hereto as Exhibit C.

6. Cooperation In Future Matters. You hereby agree that up to and following the date of this Agreement, you shall cooperate with Heritage’s reasonable requests relating to matters that pertain to your employment by Heritage, including, without limitation, providing information, limited consultation and/or transition assistance as to such matters, participating in legal proceedings (including but not limited to any proceedings related to the pending action, Paul J. Donahue, et al. v. Heritage Property Investment Trust, Inc., Suffolk Superior Court, Civil Action

Number 01-5006-A), investigations or audits on behalf of Heritage, or otherwise making yourself reasonably available to Heritage for other related purposes. Any such cooperation shall be performed at times scheduled taking into consideration your other commitments. Additionally, you shall be compensated at a reasonable hourly or per diem rate to be agreed by the parties for any such cooperation performed following the Separation Date. Following the Separation Date, you shall not be required to perform such cooperation to the extent it conflicts with any requirements of exclusivity of service for another employer or otherwise, nor in any manner that in your good faith belief of would conflict with your rights under or ability to enforce this Agreement.

7. Mutual Non Disparagement. From and after the date of this Agreement, you shall not make any remarks, statements or comments to any third party disparaging the integrity or reputation of Heritage and its subsidiaries and their respective employees, officers, directors, affiliates and principal shareholders. From and after the date of this Agreement, Heritage will not, and will use its best efforts to cause its and its subsidiaries’ employees officers, directors and principal shareholders (and the officers and directors of such principal shareholders) not to, make any remarks, statements or comments to any third party disparaging your integrity or reputation.
