The Merger shall become effective (the "Effective Time") when the Articles of Merger are accepted for record by the SDAT or such other time, if any, as Bay and Avalon shall specify in the Articles of Merger. The Merger shall have the effects prescribed in Section 3-114 of the Maryland General Corporation Law ("MGCL"). The date on which the Effective Time occurs is referred to as the "Effective Date." -7- 2.5. Tax Consequences.

If any officer listed on or appointed in accordance with Exhibit A ceases to be a full-time employee of Bay or Avalon prior to the Effective Time, or if any director, committee member or committee chairman listed or designated on Exhibit A is not serving as a director at the Effective Time, the Board of Directors of Bay or Avalon, as the case may be, after consultation with the other party, shall designate another person to serve in such person's stead in accordance with Exhibit A. ARTICLE III MERGER CONSIDERATION; EXCHANGE PROCEDURES 3.1. Merger Consideration. Subject to the provisions of this Agreement, at the Effective Time, automatically by virtue of the Merger and without any action on the part of any party or stockholder: (a) Outstanding Avalon Common Stock. Each share (excluding (i) shares held by Avalon or any of its Subsidiaries or by Bay or any of its Subsidiaries, other than in a fiduciary capacity ("Treasury Shares")) of the common stock, par value $.01 per share, of Avalon, including each attached right (a "Avalon Right") issued pursuant to the Rights Agreement, dated as of March 9, 1998, as amended (the "Avalon Rights Agreement"), between Avalon and the Rights Agent named therein (the "Avalon Common Stock"), issued and outstanding immediately prior to the Effective Time shall be converted into and become the right to receive 0.7683 shares (subject to adjustment as set forth herein, the "Exchange Ratio") of common stock, par value $.01 per share, of Bay (the "Bay Common Stock").

Each share of Avalon 9% Series A Cumulative Redeemable Preferred Stock, par value $.01 per share, liquidation preference $25 per share (the "Avalon Series A Preferred Stock"), excluding any Treasury Shares, issued and outstanding immediately prior to the Effective Time shall become and be converted into the right to -8- receive one share of a newly created series of preferred stock of the Surviving Corporation (the "Surviving Corporation Series F Preferred Stock") having terms (to be set forth in the charter of the Surviving Corporation) substantially identical to those of the Avalon Series A Preferred Stock. Each share of Avalon 8.96% Series B Cumulative Redeemable Preferred Stock, par value $.01 per share, liquidation preference $25 per share (the "Avalon Series B Preferred Stock," collectively with the Avalon Series B Preferred Stock, the "Avalon Preferred Stock"), excluding any Treasury Shares, issued and outstanding immediately prior to the Effective Time, shall become and be converted into the right to receive one share of a newly created series of preferred stock of the Surviving Corporation (the "Surviving Corporation Series G Preferred Stock") having terms (to be set forth in the charter of the Surviving Corporation) substantially identical to those of the Avalon Series B Preferred Stock. (c) Outstanding Bay Common Stock. Each share of Bay Common Stock, including each attached Bay Right (unless redeemed prior to the Effective Time), issued and outstanding immediately prior to the Effective Time shall remain outstanding following the Effective Time. (d) Outstanding Bay Preferred Stock.

Rights as Stockholders; Stock Transfers. At the Effective Time, holders of Avalon Stock shall cease to be, and shall have no rights as, stockholders of Avalon, other than to receive any dividend or other distribution with respect to such Avalon Stock with a record date occurring prior to the Effective Time and to receive the consideration provided under this Article III. After the Effective Time, there shall be no transfers on the stock transfer books of Avalon of shares of Avalon Stock. 3.3. Fractional Shares. Notwithstanding any other provision hereof, no fractional shares of Bay Common Stock and no certificates or scrip therefor, or other evidence of ownership thereof, will be issued in the Merger; instead, Bay shall pay to each holder of Avalon Common Stock who would otherwise be entitled to a fractional share of Bay Common Stock (after taking into account all Old Certificates delivered by such holder) an amount in cash to be paid in lieu of fractional shares (without interest) determined by multiplying such fraction by the average of the last sale prices of Bay Common Stock, as reported by the NYSE Composite Transactions reporting system (as reported in The Wall Street Journal or, if not reported therein, in another authoritative source), for the five NYSE trading days immediately preceding the Effective Date. 3.4. Exchange Procedures. (a) At or prior to the Effective Time, Bay shall deposit, or shall cause to be deposited, with a bank or trust company selected by Bay and reasonably acceptable to Avalon (the "Exchange Agent"), for the benefit of the holders of certificates formerly representing shares of Avalon Stock ("Old Certificates"), for exchange in accordance -9- with this Article III, certificates representing the shares of Bay Stock ("New Certificates") and an estimated amount of cash to be paid in lieu of fractional shares (such cash and New Certificates, together with any dividends or distributions with respect thereto (without any interest thereon), being hereinafter referred to as the "Exchange Fund") to be paid pursuant to this Article III in exchange for outstanding shares of Avalon Stock. (b) As promptly as practicable after the Effective Date, Bay shall send or cause to be sent to each former holder of record of shares (other than Treasury Shares) of Avalon Stock immediately prior to the Effective Time transmittal materials for use in exchanging such stockholder's Old Certificates for the consideration set forth in this Article III. Bay shall cause the New Certificates into which shares of a stockholder's Avalon Stock are converted on the Effective Date and/or any check in respect of any fractional share interests or dividends or distributions which such person shall be entitled to receive to be delivered to such stockholder upon delivery to the Exchange Agent of Old Certificates representing such shares of Avalon Stock (or indemnity reasonably satisfactory to Bay and the Exchange Agent, if any of such certificates are lost, stolen or destroyed) owned by such stockholder. No interest will be paid on any such cash to be paid pursuant to this Article III upon such delivery. (c) Notwithstanding the foregoing, neither the Exchange Agent nor any party hereto or any affiliate thereof shall be liable to any former holder of Avalon Stock for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar laws. (d) No dividends or other distributions with respect to Bay Stock with a record date occurring after the Effective Time shall be paid to the holder of any unsurrendered Old Certificate representing shares of Avalon Stock converted in the Merger into shares of such Bay Stock until the holder thereof shall surrender such Old Certificate in accordance with this Article III. After the surrender of an Old Certificate in accordance with this Article III, the record holder thereof shall be entitled to receive any such dividends or other distributions, without any interest thereon, which theretofore had become payable with respect to shares of Bay Stock represented by such Old Certificate. (e) Any portion of the Exchange Fund that remains unclaimed by the stockholders of Avalon for twelve months after the Effective Time shall be paid to Bay. Any stockholders of Avalon who have not theretofore complied with this Article III shall thereafter look only to Bay for payment of the shares of Bay Stock, cash in lieu of any fractional shares and unpaid dividends and distributions on the Bay Stock deliverable in respect of each share of Avalon Stock such stockholder holds as determined pursuant to this Agreement, in each case, without any interest thereon. 3.5. Anti-Dilution Provisions. In the event Bay or Avalon changes (or establishes a record date for changing) the number of, or provides for the exchange of, shares of Bay Common Stock or Avalon Common Stock issued and outstanding prior to the Effective Date as a result of a stock split, stock dividend, recapitalization, reclassification, reorganization or similar transaction with respect to the outstanding Bay Common Stock or Avalon Common Stock and -10- the record date therefor shall be prior to the Effective Date, the Exchange Ratio shall be proportionately and appropriately adjusted. 3.6. Treasury Shares. Each of the shares of Avalon Stock constituting Treasury Shares immediately prior to the Effective Time shall be canceled and retired at the Effective Time and no consideration shall be issued in exchange therefor. 3.7. Options. (a) At the Effective Time, all employee and director stock options to purchase shares of Avalon Common Stock (each, a "Avalon Stock Option"), which are then outstanding and unexercised, shall cease to represent a right to acquire shares of Avalon Stock and shall be converted automatically into options to purchase shares of Bay Common Stock, and Bay shall assume each such Avalon Stock Option subject to the terms of any of the stock option plans listed under "Stock Plans" in Section 5.3(l)(i) of Avalon's Disclosure Schedule (collectively, the "Avalon Stock Option Plans"), and the agreements evidencing grants thereunder; provided, however, that from and after the Effective Time, (i) the number of shares of Bay Common Stock purchasable upon exercise of such Avalon Stock Option shall be equal to the number of shares of Avalon Common Stock that were purchasable under such Avalon Stock Option immediately prior to the Effective Time multiplied by the Exchange Ratio, rounding to the nearest whole share, and (ii) the per share exercise price under each such Avalon Stock Option shall be adjusted by dividing the per share exercise price of each such Avalon Stock Option by the Exchange Ratio, rounding to the nearest cent. The terms of each Avalon Stock Option shall, in accordance with its terms, be subject to further adjustment as appropriate to reflect any stock split, stock dividend, recapitalization or other similar transaction with respect to Bay Common Stock on or subsequent to the Effective Date. Notwithstanding the foregoing, the number of shares and the per share exercise price of each Avalon Stock Option which is intended to be an "incentive stock option" (as defined in Section 422 of the Code) shall be adjusted in accordance with the requirements of Section 424 of the Code. Accordingly, with respect to any incentive stock options, fractional shares shall be rounded down to the nearest whole number of shares and where necessary the per share exercise price shall be rounded up to the nearest cent. (b) At or prior to the Effective Time, Bay shall reserve for issuance the number of shares of Bay Common Stock necessary to satisfy Bay's obligations under Section 3.7(a). At the Effective Time, Bay shall file with the SEC a registration statement on an appropriate form under the Securities Act with respect to the shares of Bay Common Stock subject to options to acquire Bay Common Stock issued pursuant to Section 3.7(a) hereof, and shall use its best efforts to maintain the current status of the prospectus contained therein, as well as comply with any applicable state securities or "blue sky" laws, for so long as such options remain outstanding.

(vii) All properties currently under development or construction by it or its Subsidiaries and all properties currently proposed for acquisition, development or commencement of construction prior to the Effective Time by it and its Subsidiaries are listed as such on its Disclosure Schedule. All executory agreements entered into by it or any of its Subsidiaries relating to the development or construction of multifamily residential or other real estate properties (other than agreements for architectural, engineering, planning, accounting, legal or other professional services, or construction agreements for material or labor) are listed on its Disclosure Schedule. Copies of such agreements, all of which have previously been delivered or made available to the other party, are listed on its Disclosure Schedule and are true and correct. (p) Environmental Matters. (A) Neither it nor any of its Subsidiaries or, to the best of its knowledge, any other person has caused or permitted the unlawful presence of any hazardous substances, hazardous materials, toxic substances or waste materials (collectively, "Hazardous Materials") on or under any of its Properties and (B) no unlawful spills, releases, discharges or disposals of Hazardous Materials have occurred or are presently occurring on, under or from its Properties as a result of any construction on or operation and use of such Properties. In connection with the construction on or operation and use of its Properties, it and its Subsidiaries have not failed to comply in any material respect with all applicable local, state and federal environmental laws, regulations, ordinances and administrative and judicial orders relating to the generation, recycling, reuse, sale, storage, handling, transport and disposal of any Hazardous Materials. (q) Taxes. Each of it and its Subsidiaries (A) has filed (or there has been filed on its behalf) all material returns, declarations, reports estimates, information returns and statements required to be filed under federal, state, local or any foreign Tax laws ("Tax Returns"), and all such Tax Returns are accurate and complete in all material respects, and (B) has paid (or payment has been made on its behalf) all Taxes shown on such Tax Returns as required to be paid by it. The most recent audited financial statements contained in its SEC Documents reflect an adequate reserve for all material Taxes payable by it and its Subsidiaries for all taxable periods and portions thereof through the date of such financial statements. Since September 30, 1997, it has incurred no liability for Taxes under Sections 857(b), 860(c) or 4981 of the Code, including any Tax arising from a prohibited transaction described in Section 857(b)(6) of the Code, and neither it nor any of its Subsidiaries has incurred any material liability for Taxes other than in the ordinary course of business. No event has occurred, and no condition or circumstance exists, which presents a material risk that any material Tax described in the preceding sentence will be imposed upon it. To the best of its knowledge, no deficiencies for any Taxes have been proposed, asserted or assessed against it or any of its Subsidiaries, and no requests for waivers of the time to assess any such Taxes are pending. It (A) has been organized in conformity with the -23- requirements for qualification as a REIT, (B) has operated, and intends to continue to operate, in such a manner as to qualify as a REIT for the current period through the Closing Date and (C) has not taken or omitted to take any action which would reasonably be expected to result in a challenge to or revocation of its status as a REIT, and to the best of its knowledge, no such challenge or revocation is pending or threatened. Each of its Subsidiaries which is a partnership, joint venture or limited liability company (i) has been treated since such Subsidiary's formation and continues to be treated for federal income tax purposes as a partnership and not as a corporation or as an association taxable as a corporation and (ii) has not since the later of such Subsidiary's formation or the acquisition by Bay (in the case of Bay's Subsidiaries) or Avalon (in the case of Avalon's Subsidiaries) of a direct or indirect interest therein, owned any assets (including securities) that would cause such party to violate Section 856(c)(5) of the Code. Each of its Subsidiaries which is a corporation has been since its formation a qualified REIT subsidiary under Section 856(i) of the Code. Neither it nor any of its Subsidiaries holds any asset (x) the disposition of which would be subject to rules similar to Section 1374 of the Code as a result of a notice under Internal Revenue Service Notice 88-19 or (y) which is subject to a consent filed pursuant to Section 341(f) of the Code and the regulations thereunder. (r) Investment Company Act of 1940. Neither it nor any of its Subsidiaries is, or at the Effective Time will be, required to be registered under the Investment Company Act of 1940, as amended. (s) HSR Act. For purposes of determining whether compliance with the HSR Act is required, it confirms that the conduct of its business consists solely of investing in, owning and operating real estate for the benefit of its stockholders. (t) Tax-Exempt Financing. Since October 31, 1997, no tax-exempt bonds have been issued or reissued of which it is a beneficiary. (u) Conversion of Bay Preferred Stock. In the case of Bay, Bay has entered into agreements (true, correct and complete copies of which have previously been provided to Avalon), which are binding and enforceable and in full force and effect, with the sole holder of the shares of Bay Series A Preferred Stock and Bay Series B Preferred Stock (the "Bay Preferred Holder") to the effect that, (i) two business days after the record date for the Bay Meeting, shares of Bay Series A Preferred Stock and Bay Series B Preferred Stock shall be converted into a number of common shares of Bay Common Stock equaling 4.9% of the total issued and outstanding shares of Bay Common Stock as of the date thereof, and (ii) the Bay Preferred Holder agrees to approve and agree to certain modifications to the terms of such Bay Series A Preferred Stock, all as more fully set forth in such agreements. (v) No Material Adverse Effect. Since September 30, 1997, except as disclosed in its SEC Documents filed with the SEC on or before the date hereof, (i) it and its Subsidiaries have conducted their respective businesses in the ordinary and usual course (excluding the incurrence of expenses related to this Agreement and the transactions contemplated hereby) and (ii) no event has occurred or circumstance arisen that, individually or taken together with all -24- other facts, circumstances and events (described in any paragraph of Section 5.3 or otherwise), is reasonably likely to have a Material Adverse Effect with respect to it. ARTICLE VI COVENANTS Bay hereby covenants to and agrees with Avalon, and Avalon hereby covenants to and agrees with Bay, that: 6.1. Best Efforts. Subject to the terms and conditions of this Agreement, it shall use its reasonable best efforts in good faith to take, or cause to be taken, all actions, and to do, or cause to be done, all things necessary, proper or desirable, or advisable under applicable laws, so as to permit consummation of the Merger as promptly as practicable and otherwise to enable consummation of the transactions contemplated hereby, including effecting all filings and obtaining (and cooperating with the other party hereto to obtain) any permit, consent, authorization, order or approval of, or any exemption by, any Governmental Entity and any other third party that is required to be obtained by Bay or Avalon or any of their respective Subsidiaries in connection with the Merger and the other transactions contemplated by this Agreement, and using reasonable efforts to lift or rescind any injunction or restraining order or other order adversely affecting the ability of the parties to consummate the transactions contemplated hereby, and using reasonable efforts to defend any litigation seeking to enjoin, prevent or delay the consummation of the transactions contemplated hereby or seeking material damages, and each shall cooperate fully with the other parties hereto to that end. 6.2. Stockholder Approvals. Each of them shall take, in accordance with applicable law, applicable stock exchange rules and its articles of incorporation and by-laws, all action necessary to convene, respectively, an appropriate meeting of stockholders of Bay to consider and vote upon the approval of this Agreement and the Merger and any other matters required to be approved by Bay stockholders for consummation of the Merger (including any adjournment or postponement, the "Bay Meeting"), and an appropriate meeting of stockholders of Avalon to consider and vote upon the approval of this Agreement and any other matters required to be approved by Avalon's stockholders for consummation of the Merger (including any adjournment or postponement, the "Avalon Meeting"; and each of the Bay Meeting and the Avalon Meeting, a "Meeting"), as promptly as practicable after the date hereof. Subject to their respective duties under Maryland law, the Board of Directors of each of Bay and Avalon shall recommend such approval, and each of Bay and Avalon shall take all reasonable lawful action to solicit such approval by its stockholders. 6.3. Registration Statement. (a) Bay and Avalon agree to cooperate in the preparation of a registration statement on Form S-4 (the "Registration Statement") to be filed by Bay with the SEC in connection with the issuance of Bay Stock in the Merger (including the joint proxy statement and prospectus and other proxy solicitation materials of Bay and Avalon constituting a part thereof (the "Joint Proxy Statement") and all related documents). Bay and Avalon agree to file a draft of the Joint Proxy Statement with the SEC as promptly as practicable, -25- but in no event later than 45 days after the date hereof. Each of Bay and Avalon agrees to use all reasonable efforts to cause the Registration Statement to be filed and declared effective under the Securities Act as promptly as reasonably practicable after the SEC has cleared the Joint Proxy Statement. Bay also agrees to use all reasonable efforts to obtain all necessary state securities law or "blue sky" permits and approvals required to carry out the transactions contemplated by this Agreement. Avalon agrees to promptly furnish to Bay all information concerning Avalon, its Subsidiaries, officers, directors and stockholders as may be reasonably requested in connection with the foregoing. (b) Each of Bay and Avalon agrees, upon request, to furnish the other party with all information concerning itself, its Subsidiaries, directors, officers and stockholders and such other matters as may be reasonably necessary or advisable in connection with the Registration Statement, the Joint Proxy Statement or any filing, notice or application made by or on behalf of such other party or any of its Subsidiaries to any Governmental Entity in connection with the transactions contemplated hereby. Each of Bay and Avalon agrees, as to itself and its Subsidiaries, that none of the information supplied or to be supplied by it for inclusion or incorporation by reference in (i) the Registration Statement will, at the time the Registration Statement and each amendment or supplement thereto, if any, becomes effective under the Securities Act, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and (ii) the Joint Proxy Statement and any amendment or supplement thereto will, at the date of mailing to stockholders and at the times of the Bay Meeting and the Avalon Meeting, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading or any statement which, in the light of the circumstances under which such statement is made, will be false or misleading with respect to any material fact, or which will omit to state any material fact necessary in order to make the statements therein not false or misleading or necessary to correct any statement in any earlier statement in the Joint Proxy Statement or any amendment or supplement thereto. Each of Bay and Avalon further agrees that if it shall become aware prior to the Effective Date of any information that would cause any of the statements in the Joint Proxy Statement to be false or misleading with respect to any material fact, or to omit to state any material fact necessary to make the statements therein not false or misleading, it shall promptly inform the other party thereof and shall take the necessary steps to correct the Joint Proxy Statement. (c) In the case of Bay, Bay will advise Avalon, promptly after Bay receives notice thereof, of the time when the Registration Statement has become effective or any supplement or amendment has been filed, of the issuance of any stop order or the suspension of the qualification of the Bay Stock for offering or sale in any jurisdiction, of the initiation or threat of any proceeding for any such purpose, or of any request by the SEC for the amendment or supplement of the Registration Statement or for additional information. 6.4. Press Releases. It will consult with the other party before issuing any press release with respect to the transactions contemplated by this Agreement and will not, without the prior approval of the other party hereto, issue any press release or written statement for -26- general circulation relating to the transaction contemplated hereby, except as otherwise required by applicable law or regulation or the rules of the NYSE or PCX. 6.5. Access; Information. (a) Upon reasonable notice and subject to applicable laws relating to the exchange of information, it shall, and shall cause its Subsidiaries to, afford the other party and its officers, employees, counsel, accountants and other authorized representatives, access, during normal business hours throughout the period prior to the Effective Date, to all of its properties, books, contracts, commitments and records, and to its officers, employees, accountants, counsel or other representatives, and, during such period, it shall, and shall cause its Subsidiaries to, furnish promptly to such other parties and representatives (i) a copy of each material report, schedule and other document filed by it pursuant to the requirements of federal or state securities laws (other than reports or documents that Bay or Avalon, or their respective Subsidiaries, as the case may be, are not permitted to disclose under applicable law), and (ii) all other information concerning the business, properties and personnel of it as the other may reasonably request. Neither Bay nor Avalon nor any of their respective Subsidiaries shall be required to provide access to or to disclose information where such access or disclosure would violate or contravene any law, rule, regulation, order, judgment, decree, fiduciary duty or binding agreement entered into prior to the date hereof. The parties hereto will make appropriate substitute disclosure arrangements under the circumstances in which the restrictions of the preceding sentence apply. (b) It will not use any information obtained pursuant to this Section 6.5 for any purpose unrelated to the consummation of the transactions contemplated by this Agreement and, if this Agreement is terminated, will hold all information and documents obtained pursuant to this paragraph in confidence (as provided in, and subject to the provisions of, the Confidentiality Agreement, as if it were the Receiving Party, as defined therein). No investigation by either party of the business and affairs of the other shall affect or be deemed to modify or waive any representation, warranty, covenant or agreement in this Agreement, or the conditions to either party's obligation to consummate the transactions contemplated by this Agreement. 6.6. Acquisition Proposals. From the date hereof until the earlier of the Effective Date or the termination of this Agreement, without the prior written consent of the other party hereto, it shall not, and shall cause its Subsidiaries and its and its Subsidiaries' officers, directors, agents, advisors and affiliates not to, solicit or encourage inquiries or proposals with respect to, or engage in any negotiations concerning, or provide any confidential information to, or have any discussions with, any such person relating to, any tender offer or exchange offer for, or any proposal for the acquisition of a substantial equity interest in, or a substantial portion of the assets of, or any merger or consolidation with, it or any of its Significant Subsidiaries; provided, however, that it may, and may authorize and permit its officers, directors, employees or agents to, furnish or cause to be furnished confidential information and may participate in such discussions and negotiations if its Board of Directors, after having consulted with and considered the advice of outside counsel, has determined that the failure to provide such information or participate in such negotiations and discussions could cause the members of such Board of Directors to breach their duties under applicable laws. It shall advise the other party of its receipt of any such -27- proposal or inquiry, of the substance thereof, and of the identity of the person making such proposal or inquiry within 24 hours of the receipt thereof. 6.7. Affiliate Agreements. (a) Not later than the 15th day prior to the mailing of the Joint Proxy Statement, each of Bay and Avalon shall deliver to the other, a schedule of each person that, to the best of its knowledge, is or is reasonably likely to be, as of the date of the relevant Meeting, deemed to be an "affiliate" of it (each, an "Affiliate") as that term is used in SEC Accounting Series Releases 130 and 135 and, in the case of Avalon only, in Rule 145 under the Securities Act. (b) Avalon shall use its reasonable best efforts to cause each person who may be deemed to be an Affiliate of Bay or Avalon, as the case may be, to execute and deliver to Avalon on or before the date of mailing of the Joint Proxy Statement an agreement in the form attached hereto as Exhibit B. 6.8. Takeover Laws. Neither party shall take any action that would cause the transactions contemplated by this Agreement and the Stock Option Agreements to be subject to requirements imposed by any Takeover Law and each of them shall take all necessary steps within its control to exempt (or ensure the continued exemption of) the transactions contemplated by this Agreement and the Stock Option Agreements from, or if necessary challenge the validity or applicability of, any applicable Takeover Law, as now or hereafter in effect, that purports to apply to this Agreement, the Stock Option Agreements or the transactions contemplated hereby or thereby. 6.9. No Rights Triggered. Each of Bay and Avalon shall take all steps necessary to ensure that the entering into of this Agreement and the consummation of the transactions contemplated hereby and any other action or combination of actions, or any other transactions contemplated hereby, do not and will not result in the grant of any rights to any person (i) under its charter or by-laws, (ii) under any material agreement to which it or any of its Subsidiaries is a party, or (iii) to exercise or receive certificates for Bay Rights or Avalon Rights, or acquire any property in respect of Bay Rights or Avalon Rights, under the Bay Rights Agreement or the Avalon Rights Agreement, as the case may be. 6.10. Shares Listed. In the case of Bay, Bay shall use its reasonable best efforts to list, prior to the Effective Date, on the NYSE and PCX, upon official notice of issuance, the shares of Bay Common Stock to be issued to the holders of Avalon Common Stock in the Merger. 6.11. Filings; Consents. Each of Bay and Avalon shall have the right to review in advance, and to the extent practicable each will consult with the other, in each case subject to applicable laws relating to the exchange of information, with respect to, all material written information submitted to any third party or any Governmental Entity in connection with the transactions contemplated by this Agreement. In exercising the foregoing right, each of the parties hereto agrees to act reasonably and as promptly as practicable. Each party hereto agrees that it will consult with the other party hereto with respect to the obtaining of all material permits, consents, approvals and authorizations of all third parties and Governmental Entities necessary or -28- advisable to consummate the transactions contemplated by this Agreement and each party will keep the other parties apprised of the status of material matters relating to completion of the transactions contemplated hereby. 6.12. Indemnification; Directors' and Officers' Insurance. (a) In the event of any threatened or actual claim, action, suit, proceeding or investigation, whether civil, criminal or administrative, in which any person who is now, or has been at any time prior to the date hereof, or who becomes prior to the Effective Time, a director, officer or employee of Avalon or any of its Subsidiaries or of Bay or any of its Subsidiaries is, or is threatened to be, made a party based in whole or in part on, or arising in whole or in part out of, or pertaining to this Agreement, the Stock Option Agreements, or any of the transactions contemplated hereby or thereby or any actions taken by any such person in connection herewith or therewith, whether in any case asserted or arising before or after the Effective Time, the parties hereto agree to cooperate and use their best efforts to defend against and respond thereto. It is understood and agreed that after the Effective Time, Bay shall indemnify and hold harmless, as and to the fullest extent permitted by Maryland law, each person who is now, or has been at any time prior to the date hereof, or who becomes prior to the Effective Time, a director or officer of Avalon or any of its Subsidiaries (the "Indemnified Parties") against any losses, claims, damages, liabilities, costs, expenses (including advancing reasonable attorney's fees and expenses in advance of the final disposition of any claim, suit, proceeding or investigation to each Indemnified Party to the fullest extent permitted by law upon receipt of an undertaking from such Indemnified Party to repay such advanced expenses if it is finally and unappealably determined that such Indemnified Party was not entitled to indemnification hereunder), judgments, fines and amounts paid in settlement in connection with any such threatened or actual claim, action, suit, proceeding or investigation, and in the event of any such threatened or actual claim, action, suit, proceeding or investigation (whether asserted or arising before or after the Effective Time and including any such threatened or actual claim, action, suit, proceeding or investigation based in whole or in part on, or arising in whole or in part out of, or pertaining to (i) the fact that he or she is or was a director, officer or employee of Avalon, any of Avalon's Subsidiaries or any of their respective predecessors or was prior to the Effective Time serving at the request of any such party as a director, officer, employee, fiduciary or agent of another corporation, partnership, trust or other enterprise, or (ii) this Agreement, the Stock Option Agreements, or any of the transactions contemplated hereby or thereby and all actions taken by an Indemnified Party in connection herewith or therewith), and the Indemnified Parties may retain counsel after consultation with Bay; provided, however, that (1) Bay shall have the right to assume the defense thereof and upon such assumption Bay shall not be liable to any Indemnified Party for any legal expenses of other counsel or any other expenses subsequently incurred by any Indemnified Party in connection with the defense thereof, except that if Bay elects not to assume such defense, or counsel for the Indemnified Parties reasonably advises the Indemnified Parties that there are or may be (whether or not any have yet actually arisen) issues which raise conflicts of interest between Bay and the Indemnified Parties, the Indemnified Parties may retain counsel reasonably satisfactory to them, and Bay shall pay the reasonable fees and expenses of such counsel for the Indemnified Parties, (2) Bay shall be obligated pursuant to this paragraph to pay for only one firm of counsel for all Indemnified Parties, (3) Bay shall not be liable for any settlement effected without its prior written consent (which consent shall not be unreasonably withheld) and (4) Bay shall have no obligation hereunder to -29- any Indemnified Party when and if a court of competent jurisdiction shall ultimately determine, and such determination shall have become final and nonappealable, that indemnification of such Indemnified Party in the manner contemplated hereby is prohibited by applicable law. Any Indemnified Party wishing to claim indemnification under this Section 6.12, upon learning of any such claim, action, suit, proceeding or investigation, shall notify Bay thereof, provided that the failure to so notify shall not affect the obligations of Bay under this Section 6.12 except (and only) to the extent such failure to notify materially prejudices Bay. Bay's obligations under this Section 6.12 shall continue in full force and effect for a period of six (6) years from the Effective Time; provided, however, that all rights to indemnification in respect of any claim (a "Claim") asserted or made within such period shall continue until the final disposition of such Claim. (b) Without limiting any of the obligations under paragraph (a) of this Section 6.12, Bay agrees that all rights to indemnification and all limitations of liability existing in favor of the Indemnified Parties as provided in Avalon's charter or by-laws or in the similar governing documents of any of Avalon's Subsidiaries as in effect as of the date hereof with respect to matters occurring on or prior to the Effective Time shall survive the Merger and shall continue in full force and effect, without any amendment thereto, for a period of six (6) years from the Effective Time; provided, however, that all rights to indemnification in respect of any Claim asserted or made within such period shall continue until the final disposition of such Claim; provided further, however, that nothing contained in this Section 6.12(b) shall be deemed to preclude the liquidation, consolidation or merger of Avalon or any Avalon Subsidiary, in which case all of such rights to indemnification and limitations on liability shall be deemed to so survive and continue notwithstanding any such liquidation, consolidation or merger and shall constitute rights which may be asserted against Bay. Nothing contained in this Section 6.12(b) shall be deemed to preclude any rights to indemnification or limitations on liability provided in Avalon's Amended and Restated Articles of Incorporation or the similar governing documents of any of Avalon's Subsidiaries with respect to matters occurring subsequent to the Effective Time to the extent that the provisions establishing such rights or limitations are not otherwise amended to the contrary. (c) Bay shall use its best efforts to cause the persons serving as officers and directors of Avalon immediately prior to the Effective Time to be covered for a period of six (6) years from the Effective Time by the directors' and officers' liability insurance policy maintained by Avalon (provided that Bay may substitute therefor policies of at least the same coverage and amounts containing terms and conditions which are not less advantageous to such directors and officers of Avalon than the terms and conditions of such existing policy) with respect to acts or omissions occurring prior to the Effective Time which were committed by such officers and directors in their capacity as such. (d) In the event Bay or any of its successors or assigns (i) consolidates with or merges into any other person and shall not be the continuing or surviving corporation or entity of such consolidation or merger, or (ii) transfers or conveys all or substantially all of its properties and assets to any person, then, and in each such case, to the extent necessary, proper provision shall be made so that the successors and assigns of Bay shall assume the obligations set forth in this Section 6.12. -30- (e) The provisions of this Section 6.12 are intended to be for the benefit of, and shall be enforceable by, each Indemnified Party and his or her heirs and representatives. 6.13. Compensation and Benefit Plans. (a) It is the intention of the parties that the Surviving Corporation shall formulate Compensation and Benefit Plans for the Surviving Corporation and its Subsidiaries, with respect to employees of both Bay and Avalon that provide benefits for services after the Effective Time on a basis that does not discriminate between such employees. Employees of Avalon and its Subsidiaries immediately prior to the Effective Time who become employees of the Surviving Corporation or one of its Subsidiaries immediately after the Effective Time shall be given credit for purposes of eligibility and vesting of employee benefits and benefit accrual for service with Avalon and its affiliates, and predecessors of Avalon and its affiliates, prior to the Effective Time under each benefit plan of the Surviving Corporation and its Subsidiaries to the extent such service had been credited under employee benefit plans of Avalon or its Subsidiaries, provided that no such crediting of service results in duplication of benefits. (b) In the case of Avalon Compensation and Benefit Plans under which the employees' interests are based upon Avalon Common Stock, such interests shall be based upon Bay Common Stock in accordance with Section 3.7 with respect to Avalon Stock Options and otherwise in accordance with the terms of the Avalon Compensation and Benefit Plans and in an equitable manner. 6.14. Transfer and Gains Taxes. Bay and Avalon shall cooperate in the preparation, execution and filing of all returns, questionnaires, applications or other documents regarding any real property transfer or gains, sales, use, transfer, value added stock transfer and stamp taxes, any transfer, recording, registration and other fees and any similar taxes which become payable in connection with the Transactions (together with any related interests, penalties or additions to tax, "Transfer and Gains Taxes"). From and after the Effective Time, the Surviving Company shall pay, without deduction or withholding from any amounts payable to the holders of Bay Common Stock (including former holders of Avalon Common Stock), all Transfer and Gains Taxes (other than any such taxes that are solely the liability of the holders of Bay Common Stock under applicable state law). 6.15. Headquarters. The Surviving Corporation's executive headquarters shall be located in the Alexandria, Virginia area, or in such other location where the Chief Executive Officer shall be based, and the Surviving Corporation shall have super-regional offices in the San Jose, California area, where the President and Chief Operating Officer shall be based, and in the Wilton, Connecticut area. 6.16. Notification of Certain Matters. Each of Bay and Avalon shall give prompt notice to the other of any fact, event or circumstance known to it that (i) is reasonably likely, individually or taken together with all other facts, events and circumstances known to it, to result in any Material Adverse Effect with respect to it or (ii) notwithstanding the standards set forth in Section 5.2, would cause or constitute a material breach of any of its representations, warranties, covenants or agreements contained herein. -31- 6.17. Interim Transactions Committee. Bay and Avalon shall establish an interim transactions committee (the "Interim Transactions Committee") consisting of the individuals listed on Exhibit A. Subject to any approvals that may be required by law or otherwise on the part of Bay or Avalon, the Interim Transactions Committee shall approve acquisition, budget and capital improvement activities (including activities otherwise prohibited by Article IV of this Agreement) of each of Bay and Avalon between the date hereof and the Effective Time.

No Injunction, Etc. No order, decree or injunction of any court or agency of competent jurisdiction shall be in effect, and no law, statute or regulation shall have been enacted or adopted, that enjoins, prohibits or makes illegal consummation of any of the transactions contemplated hereby; provided, however, that each of Bay and Avalon shall have used its reasonable best efforts to prevent any such rule, regulation, injunction, decree or other order, and to appeal as promptly as possible any injunction, decree or other order that may be entered. 7.5. Representations, Warranties and Covenants of Avalon. In the case of Bay's obligation to consummate the Merger: (i) each of the representations and warranties contained herein of Avalon shall be true and correct as of the date hereof and upon the Effective Date with the same effect as though all such representations and warranties had been made on the Effective Date, except for any such representations and warranties made as of a specified date, which shall be true and correct as of such date, in any case subject to the standard set forth in Section 5.2, (ii) each and all of the agreements and covenants of Avalon to be performed and complied with pursuant to this Agreement on or prior to the Effective Date shall have been duly -32- performed and complied with in all material respects, and (iii) Bay shall have received a certificate signed by the President, Chief Executive Officer or Chief Financial Officer of Avalon, dated the Effective Date, to the effect set forth in clauses (i) and (ii) of this Section 7.5. 7.6.

Bay and Avalon shall have received an opinion from Goodwin, Procter & Hoar LLP, in the case of Bay, and Wachtell, Lipton, Rosen & Katz, in the case of Avalon, dated in each case as of the Closing Date, substantially to the effect that, on the basis of the facts, representations and assumptions set forth in such opinions which are consistent with the state of facts existing at the Closing Date, the Merger will be treated for Federal income tax purposes as a reorganization within the meaning of Section 368(a) of the Code and that accordingly: (i) No gain or loss will be recognized by Bay or Avalon as a result of the Merger; (ii) No gain or loss will be recognized by the stockholders of Avalon who exchange all of their Avalon Common Stock solely for Bay Common Stock pursuant to the Merger (except with respect to cash received in lieu of a fractional share interest in Bay Common Stock); and (iii) The aggregate tax basis of the Bay Common Stock received by stockholders who exchange all of their Avalon Common Stock solely for Bay Common Stock in the Merger will be the same as the aggregate tax basis of Avalon Common Stock surrendered in exchange therefor (reduced by any amount allocable to a fractional share interest for which cash is received). In rendering such opinions, such counsel may require and rely upon representations and covenants including those contained in certificates of officers of Bay, Avalon and others, reasonably satisfactory in form and substance to such counsel. -33- 7.9. Tax Opinion Relating to REIT Status. Bay and Avalon shall have received an opinion from Goodwin, Procter & Hoar LLP, dated as of the Closing Date, substantially to the effect that the Surviving Corporation will continue to qualify as a REIT for federal income tax purposes immediately after the Effective Time. In rendering such opinion, Goodwin, Procter & Hoar LLP may require and rely upon customary assumptions, representations and covenants including those contained in certificates of officers of Bay, Avalon and others, reasonably satisfactory in form and substance to such counsel. 7.10. NYSE Listing. The shares of Bay Common Stock issuable pursuant to this Agreement shall have been approved for listing on the NYSE, subject to official notice of issuance. 7.11. Rights Agreements. In the case of Bay's obligation to consummate the Merger, there shall exist no "Share Acquisition Date", "Distribution Date" or "Triggering Event" (as each of such terms is defined in the Avalon Rights Agreement) under the Avalon Rights Agreement. In the case of Avalon's obligation to consummate the Merger, there shall exist no "Stock Acquisition Date", "Distribution Date" or "Triggering Event" (as each of such terms is defined in the Bay Rights Agreement) under the Bay Rights Agreement. 7.12. REIT Income. In the case of Bay's obligation to consummate the Merger, prior to the Effective Date, to the extent necessary to satisfy the requirements of Section 857(a)(1) of the Code for the taxable year of Avalon ending at the Effective Time (and avoid the payment of tax with respect to undistributed income), Avalon shall declare a dividend (the "Final Company Dividend") to holders of Avalon Common Shares, the record date for which shall be the close of business on the last business day prior to the Effective Time, in an amount equal to the minimum dividend sufficient to permit Avalon to satisfy such requirements. If Avalon determines it necessary to declare the Final Company Dividend, it shall notify Bay at least 15 days prior to the Effective Date. It is specifically provided, however, that a failure to satisfy the conditions set forth in Sections 7.5 or 7.12 shall only constitute a condition if asserted by Bay, and a failure to satisfy the condition set forth in Section 7.6 shall only constitute a condition if asserted by Avalon. ARTICLE VIII TERMINATION 8.1. Termination. This Agreement may be terminated, and the Merger may be abandoned: (a) Mutual Consent. At any time prior to the Effective Time, by the mutual consent of Bay and Avalon in a written instrument, if the Board of Directors of each so determines by vote of a majority of the members of its entire Board. -34- (b) Breach. At any time prior to the Effective Time, by Bay or Avalon (provided that the terminating party is not then in material breach of any representation, warranty, covenant or other agreement contained herein), if its Board of Directors so determines by vote of a majority of the members of its entire Board, in the event of either: (i) a breach by the other party of any representation or warranty contained herein (subject to the standards set forth in Section 5.2), which breach cannot be or has not been cured within 30 days after the giving of written notice to the breaching party of such breach; or (ii) a material breach by the other party of any of the covenants or agreements contained herein, which breach cannot be or has not been cured within 30 days after the giving of written notice to the breaching party of such breach. (c) Delay. At any time prior to the Effective Time, by Bay or Avalon, if its Board of Directors so determines by vote of a majority of the members of its entire Board, in the event that the Merger is not consummated by November 30, 1998, except to the extent that the failure of the Merger then to be consummated arises out of or results from the failure of the party seeking to terminate this Agreement to perform or observe the covenants and agreements of such party set forth herein. (d) No Approval. By Bay or Avalon, if its Board of Directors so determines by a vote of a majority of the members of its entire Board, in the event (i) any Governmental Entity of competent jurisdiction shall have issued a final nonappealable order enjoining or otherwise prohibiting the consummation of the transactions contemplated by this Agreement, or (ii) any stockholder approval required by Section 7.1 herein is not obtained at the Bay Meeting or the Avalon Meeting. (e) Recommendation Altered. By either the Board of Directors of Bay or the Board of Directors of Avalon, if the Board of Directors of the other party shall have withdrawn, modified or changed in a manner adverse to the terminating party its approval or recommendation of this Agreement and the transactions contemplated hereby. 8.2. Effect of Termination and Abandonment. In the event of termination of this Agreement and the abandonment of the Merger pursuant to this Article VIII, no party to this Agreement shall have any liability or further obligation to any other party hereunder except (i) as set forth in Section 8.3, (ii) as set forth in Section 9.1, and (iii) that termination will not relieve a breaching party from liability for any willful breach of this Agreement giving rise to such termination. 8.3. Break-Up Expenses. In addition to any other fees and expenses payable under this Agreement, in the event of termination of this Agreement under Section 8.1(b) or Section 8.1(e) above, or in the event that either party terminates this Agreement pursuant to clause (ii) of Section 8.1(d) due to the failure to obtain the approval of stockholders of the other party, such terminating party ("Recipient") shall be entitled to receive from the other party ("Payor") Break-Up Expenses at the time of such termination or at such other time or times as provided for in this Section 8.3. "Break-Up Expenses" shall be an amount equal to $10,000,000. Upon termination necessitating the payment of Break-Up Expenses, Payor shall immediately deposit into escrow with an escrow agent selected by Recipient an amount in cash equal to the Break-Up Ex- -35- penses. The escrow agent shall pay to Recipient an amount equal to the lesser of (i) the Break-Up Expenses and (ii) the maximum amount that can be paid to Recipient without causing Recipient, to fail to meet the requirements of Sections 856(c)(2) and (3) of the Code determined as if the payment of such amount did not constitute income described in Sections 856(c)(2)(A)-(H) and 856(c)(3)(A)-(I) of the Code ("Qualifying Income"), as determined by the independent accountants of Recipient. In the event that all or any portion of the Break-Up Expenses remains in escrow after payment of the amount, if any, required by the preceding sentence, the escrow agreement shall provide that the Recipient shall not be entitled to the remainder of the Break-Up Expenses and no amount thereof shall be released to Recipient unless and until the escrow agent receives any one or combination of the following: (i) a letter from Recipient's outside counsel ("Break-Up Expenses Tax Opinion") indicating that it has received a ruling from the IRS the effect of which holds that Recipient's receipt of the Break-Up Expenses would not jeopardize its status as a REIT ("REIT Requirements"), and that receipt by Recipient of the remaining balance of the Break-Up Expenses following the receipt of and pursuant to such ruling would not be deemed constructively received prior thereto (in which case the escrow agent shall release the remainder of the Break-Up Expenses in escrow to Recipient) or (ii) a letter (or a series of letters) from the independent accountants of Recipient, each indicating any additional amounts that Recipient can be entitled to and can be paid at that time without causing it to fail to meet the REIT Requirements (in which case the escrow agent shall release such additional amounts from escrow to Recipient). The obligation of Payor to pay any unpaid portion of the Break-Up Expenses shall terminate three years from the date hereof, and any unpaid portion of the Break-Up Expenses remaining in escrow three years from the date hereof shall be released to Payor and the escrow shall terminate at that time.
