Dear Sam:

     Reference is made to your Employment Agreement dated December 31, 2001 (the “Employment Agreement”) between you and AvalonBay Communities, Inc. (the “Company,” a term which for purposes of this Agreement includes its related or affiliated entities). This letter agreement (this “Separation Agreement”) sets forth the terms under which your employment with the Company will terminate and the Employment Agreement will be terminated (except for certain provisions, which will survive as described below).

1. Departure Date and Consulting Services.

     (a) Termination of Employment and Departure Date. The effective date of the termination of your employment and office(s) with the Company and any of its related or affiliated entities will be April 30, 2005 (such date, or such earlier date as the parties may subsequently mutually agree each in their sole discretion, the “Departure Date”), and your termination on such date shall constitute a termination of your employment by the Company without cause under the Employment Agreement. By entering into this Separation Agreement, you are acknowledging that, as of the Departure Date, you are no longer an officer or employee of the Company and, to the extent applicable, you will no longer be a director and/or officer of any and all entities that are affiliates of the Company.

     (b) Consulting Services and Termination Date. From and after the Departure Date, and until April 30, 2006 (April 30, 2006 or such earlier date as may apply in the event that the Company terminates the consulting arrangement as contemplated by the last sentence of this paragraph in Section 1(b) or by Section 5(b) or 11(b) below, the “Termination Date”), you will perform services for the Company as a consultant. The period from the Departure Date to the Termination Date is referred to herein as the “Consulting Period”. The legal status of your consultancy during the Consulting Period will be as an independent contractor. You agree to make yourself available during the Consulting Period to perform consulting services on a part-time basis only (not to exceed 15 hours per month except as agreed to by you), at times and upon notice reasonably acceptable to you. Your services as a consultant may include advising the Company about development projects that are currently in progress or in pursuit as of the Departure Date and cooperating with various litigation matters as described in Section 8, whether now or hereafter existing. The Company agrees to utilize

your consulting services at times and places which do not interfere with your post-departure business or employment activities. During the Consulting Period, you shall be free to pursue other business opportunities or employment, provided that (x) such other business opportunities or employment do not violate Section 11 of this Separation Agreement (in which case the Company’s remedy shall be limited as provided therein) or Sections 5, 7, 9 or 10 and (y) you do not, without the Company’s written consent (which it may withhold in its sole discretion) pursue, or actively attempt to disrupt or interfere with, any development communities, development rights or development pursuits of the Company as of the Departure Date (which shall include, in all events, any development communities, development rights or development pursuits which have previously been identified in the Company’s SEC filings or press releases with respect to periods ending on or prior to March 31, 2005 (i.e., including the first quarter 2004 earnings release) and any others that you and the Company mutually agree you should be aware of as of the Departure Date as set forth in an Exhibit B to be attached hereto promptly following the Departure Date). You shall not be required to provide consulting services in a manner that unreasonably interferes with your ability to pursue other business opportunities or employment. Upon presentation of invoices, the Company will reimburse you for any reasonable out-of-pocket expenses you incur in providing consulting services hereunder, such as any required travel expenses, provided that in the event you expect to incur meaningful out-of-pocket expenses such as airfare, you must receive advance permission from the Company. In no event would reimbursement of out-of-pocket expenses include overhead items such as office, telephone or clerical support except as the Company may otherwise agree in its sole discretion. Your compensation for services provided during the Consulting Period shall be $60,000, payable at the rate of $5,000 per month, to be paid before the end of each month starting in May 2005. The Company may terminate the Consulting Period if, following written notice and at least a 30 day opportunity to cure, you fail to perform your obligations under this Section 1(b).

Nothing in this Separation Agreement or otherwise shall be construed as identifying you or permitting you to identify yourself as an employee, agent or legal representative of the Company during the Consulting Period for any purpose whatsoever. You will not be authorized to transact business, incur obligations, sell goods, receive payments, solicit orders or assign or create any obligation of any kind, express or implied, on behalf of the Company, or to bind it in any way whatsoever, or to make any promise, warranty or representation on behalf of the Company with respect to any matter, except as expressly authorized in writing by a duly authorized officer of the Company. You shall not use any of the Company’s trade names, trademarks, service names or servicemarks without the prior written approval of the Company.

(c) Technical Support. For a reasonable period of time following the Departure Date to be mutually reasonably agreed upon, but in no event beyond the Termination Date, the Company will maintain for you a direct dial telephone number of (203) 801-3311, including voicemail, and an email account with the address of Samf@avalonbay.com and Sam_Fuller@avalonbay.com (the Company may require that emails received at the Company email account be forwarded to a non-Company email account that you maintain).

In the event that a Change in Control (as defined in the Employment Agreement) of the Company occurs prior to August 24, 2005, then promptly thereafter the Company will pay to you an additional amount which is calculated such that the amount paid to you under this clause 2(c) plus such additional amount is equal to the increased amount as provided in Section 7 (c)(vi) of the Employment Agreement and as calculated as of your Departure Date).
(d)	Medical/Dental. The Company shall pay for the cost of premiums for medical and dental insurance coverage provided to you and your children in accordance with the continuation requirements of COBRA for up to eighteen (18) months and for the cost of premiums for medical and dental coverage for up to an additional six (6) months under a comparable policy that you procure (for purposes of this Section 2(d), the cost of premiums for such additional coverage shall be deemed to be equal to the cost of premiums for COBRA coverage). Promptly following the Departure Date, the Company shall pay you a lump sum cash amount equal to the full amount due under this provision, and the Company shall thereafter have no further obligation to you under this provision and you shall be responsible for maintaining such policy(ies) and paying the premiums related thereto each month.

(f)	Common Stock.

  (i) On or about February 11, 2005, the Company granted to you 8,041 shares in respect of 2004 (the “2005 Shares”), of which 20% were vested and the remaining 80% were granted subject to vesting in accordance with the Company’s current practices.

(ii)	All shares of the Company’s stock that you were granted as Restricted Shares prior to the Departure Date (including the 2005 Shares) and that have not yet vested will vest as of the Departure Date. In addition to the above, the Company will grant to you, on the Departure Date, 1,637 fully vested shares in consideration of your partial-year 2005 service (the “Partial 2006 Shares”).
(iii)	To the extent the Company has not already done so, promptly following the Departure Date and subject to the restrictions set forth in paragraph 2(j) below, the Company shall deliver to you certificates representing the Partial 2006 Shares and all Restricted Shares which vest on the Departure Date, and such shares shall be freely transferable by you subject to applicable securities laws. You understand that on the Departure Date when you are granted the Partial 2006 Shares and all unvested Restricted Shares vest, you shall become liable for all applicable federal and state income tax due on the value of such stock. You may pay the withholding taxes in cash to the Company or, alternatively, the Company will cooperate in a sale of vested shares in a manner where a portion of the proceeds is directly paid over to the Company on account of withholding taxes.
(iv)	The Company will permit you to elect to have a number of the shares you otherwise would receive on the Departure Date withheld to cover your withholding taxes on such shares, provided you irrevocably make such election at a time when the Company’s insider trading window is open.

     (g) Cash Bonuses.

(i)	At or about the time when cash bonuses are made to other officers of the Company in respect of 2004 (i.e., on or about March 1, 2005), the Company paid to you (subject to withholding) a cash bonus in respect of 2004 of $425,715 (the “2004 Cash Bonus”), subject to withholding taxes.
(ii)	On or prior to the Departure Date, the Company will also pay to you a prorated cash bonus of $68,074 for 2005 (subject to withholding) (the “Partial 2005 Cash Bonus”).

(iii)	In addition to the above, the Company will grant to you, on or prior to the Departure Date, 16,267 fully vested employee stock options in consideration of your partial-year 2005 service (the “Partial 2006 Options”).
(iv)	The Company has taken or will take such action such that the 2005 Options and Partial 2006 Options (the “Extended Term Options”), when granted, have a term that expires on their fifth anniversary of the date of grant, regardless of death, disability or termination of employment or other business relationship with the Company, provided, however, that the term of such options shall be subject to earlier expiration as contemplated by Section 15 hereof.
(v)	Other than the Extended Term Options (which will expire five years after their grant date), your other options, in accordance with the term of each individual option agreement, will expire a period of time (such period generally being 3 months or 1 year, depending on the exact term provided in the applicable option agreement and any addendum thereto, and such period referred to herein as the “Tail Period”) following the Termination Date. The Company acknowledges that, during your Consulting Period, you will have an “other business relationship” with the Company within the meaning set forth in your stock option agreements and the Company’s stock incentive plan. For clarification, it is noted that the Tail Period in no event shall cause an option to extend beyond its original 10-year term. A list of all of the stock options and their respective outside exercise dates is outlined in Exhibit C attached hereto.

     (i) Deferred Compensation. Pursuant to the Company’s deferred compensation plan, the Company will pay to you any amounts owed there under in accordance with the Company’s deferred compensation plan document and your elections there under.

     (j) Offset for Withholding Tax and Loans. You acknowledge that income taxes or other legally mandated withholding will be due upon the payment of any cash compensation provided for herein, the transfer or vesting of stock or the exercise of stock options and the Company will not be obligated to deliver to you any share certificates until you have satisfied all withholding tax obligations. You agree and authorize the Company to withhold cash payments otherwise due to you under this Separation Agreement, and to use such withheld payments for the purpose of satisfying any obligations which you may have for taxes other legally-mandated withholding until such obligations are fully satisfied. In the event that the payments withheld are insufficient to satisfy such obligations, you agree to make any additional payments necessary directly to the Company until all such obligations are satisfied.

     (k) Disability Insurance. Promptly following the Departure Date, the Company shall pay you a lump sum cash amount equal to 24 months premiums on the current disability policy

     12. Exclusivity. This Separation Agreement sets forth all the consideration to which you are entitled by reason of the termination of your employment, and you agree that you hereby waive any entitlement or eligibility for any payments or benefits under any other Company severance, bonus, retention or incentive policy, arrangement or plan.

          (c) In the event of any dispute, this Separation Agreement will be construed as a whole, will be interpreted in accordance with its fair meaning, and will not be construed strictly for or against either you or the Company. Section headings and parenthetical explanations of section references are for convenience only and shall not be used to interpret the meaning of any provision or term of this Separation Agreement.

          (d) The law of the State of Maryland will govern any dispute about this Separation Agreement, including any interpretation or enforcement of this Separation Agreement.

If such amendment or interpretation is not possible, the illegal, invalid or unenforceable provision or portion of a provision will be severed from the remainder of this Separation Agreement and the remainder of this Separation Agreement shall be enforced to the fullest extent possible as if such illegal, invalid or unenforceable provision or portion of a provision was not included.

          (f) This Separation Agreement may be modified only by a written agreement signed by you and an authorized representative of the Company.

          (g) This Separation Agreement constitutes the entire agreement between the parties with respect to the subject matter hereof and, except as expressly provided herein, supersedes all prior agreements between the parties with respect to any related subject matter.

          (i) Notices by the Company to you shall be made to your home address as Samuel B. Fuller, 7 Indian Trail, Darien, CT 06820, telephone: (203) 655-0022., and notices by you to the Company shall be made to the attention of the Executive Vice President- Human Resources and delivered to the Company’s Alexandria office.

     15. Certain Breaches and Effect on Exercisability of Extended Term Options. In the event that you willfully and materially breach the terms of Sections 5, 6, 7, 9 or 10 hereof (a “Material Breach”) at any time after the date hereof and prior to the one year anniversary of the Termination Date then, in addition to the Company’s rights to obtain equitable relief or damages for such breach or the Company’s right to terminate the Consulting Period as provided in Section 5 for a breach of that Section, the Company may suspend the exercisability of any then outstanding Extended Term Options (any such suspended options, “Suspended Options”). The Company may suspend your right to exercise the Suspended Options by (i) filing a request for

arbitration within a reasonable time after the President or Chairman learns of the Material Breach, which request specifically states that in 30 days the Company is suspending your right to exercise, or (ii) in the event the Company reasonably determines that your asserted Material Breach is curable, by sending you a written notice describing the Material Breach and the steps you must take to cure such Material Breach in 30 days. In the event that the Company asks you to cure a Material Breach and you fail to cure such breach to the Company’s satisfaction within 30 days following delivery to you of written notice from the Company, the Company then may commence an arbitration proceeding, in which case your right to exercise the Suspended Options will remain suspended. In the event that an arbitrator determines that you had not committed a Material Breach, the arbitrator may award you damages caused by the suspension of your right to exercise the Suspended Options. In the event that an arbitrator determines that you had committed a Material Breach, the exercise period of the Suspended Options may be terminated by the Company immediately without further action or decision by the arbitrator, without prejudice to the Company’s right to obtain equitable relief or damages for such Material Breach; provided that an award of additional damages (if any) shall take into account termination of the Suspended Options. Nothing contained herein otherwise shall be deemed to limit the Company’s right to obtain equitable relief or damages for any breach of this agreement.
