We are filing the registration statement of which this prospectus is a part at this time to fulfill a contractual obligation to do so. We will not receive any of the proceeds from the sale of the common stock by the selling stockholders. Our common stock is listed on the New York Stock Exchange under the symbol "BXP." See "Risk Factors" on page 4 for factors you should consider before you invest in our common stock. ------------ Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities, or determined if this prospectus is truthful or complete. It is illegal for any person to tell you otherwise. ------------ The date of this prospectus is [ ]. PROSPECTUS SUMMARY This summary only highlights the more detailed information appearing elsewhere in this prospectus or incorporated herein by reference. As this is a summary, it may not contain all information that is important to you. You should read this entire prospectus carefully before deciding whether to invest in our common stock. Unless the context otherwise requires, all references to "we," "us" or "our company" in this prospectus refer collectively to Boston Properties, Inc., a Delaware corporation, and its subsidiaries, including Boston Properties Limited Partnership, a Delaware limited partnership, and their respective predecessor entities for the applicable periods, considered as a single enterprise. ------------ About Boston Properties, Inc. We are a fully-integrated, self-administered and self-managed real estate investment trust or "REIT" and one of the largest owners and developers of office properties in the United States. We conduct substantially all our business through our affiliate, Boston Properties Limited Partnership, in which we are the sole general partner and hold a controlling economic interest. Our properties are concentrated in four core markets--Boston, midtown Manhattan, Washington, D.C. and San Francisco. We have full-service offices in Boston, New York, Washington, D.C., San Francisco and Princeton, New Jersey, and achieve efficiencies of scale by operating a centralized financial control and data center at our Boston headquarters that is responsible for operating budgets, billing and payments for all of our existing and development properties. We were formed to succeed to the real estate development, redevelopment, acquisition, operating and leasing businesses associated with a predecessor company founded by Messrs. Mortimer B. Zuckerman and Edward H. Linde in 1970. We believe that we have created significant value for our tenants and investors by developing well located properties that meet the demands of today's office tenants, redeveloping underperforming assets, and continuously improving the marketing and management of our assets. Additional information regarding Boston Properties, including our audited financial statements and descriptions of Boston Properties, is contained in the documents incorporated by reference in this prospectus. See "Where You Can Find More Information" on page 5. 2 The Offering This prospectus relates to up to 1,066,229 shares of our common stock that may be offered for sale by the selling stockholders. We are registering the common stock covered by this prospectus in order to fulfill our contractual obligations under our registration rights agreements with the selling stockholders. Registration of the common stock does not necessarily mean that all or any portion of the common stock covered by this prospectus will be offered for sale by the selling stockholders. We have agreed to register the common stock under federal securities laws, but we will not receive any proceeds from the sale of any common stock offered under this prospectus. Tax Status of Boston Properties, Inc. We have elected to qualify as a real estate investment trust under Sections 856 through 860 of the Internal Revenue Code. As long as we qualify for taxation as a real estate investment trust, we generally will not be subject to federal income tax on that portion of our ordinary income and capital gains that is currently distributed to our stockholders. Even if we qualify for taxation as a real estate investment trust, we may be subject to state and local taxes on our income and property and to federal income and excise taxes on our undistributed income. 3 RISK FACTORS Before you purchase shares of our common stock from the selling stockholders you should be aware that there are various risks in making an investment in our common stock, including those in our Annual Report on Form 10-K for the year ended December 31, 2001, incorporated by reference in this prospectus.

When we use the words "anticipate," "assume," "believe," "estimate," "expect," "intend" and other similar expressions, they generally identify forward-looking statements. Forward-looking statements include, for example, statements relating to acquisitions and related financial information, development activities, business strategy and prospects, future capital expenditures, sources and availability of capital, environmental and other regulations and competition. You should exercise caution in interpreting and relying on forward-looking statements since they involve known and unknown risks, uncertainties and other factors which are, in some cases, beyond our control and could materially affect our actual results, performance or achievements. Some of the factors that could cause our actual results, performance or achievements to differ materially from those expressed or implied by forward-looking statements include, but are not limited to, the following: o we are subject to general risks affecting the real estate industry, including the need to enter into new leases or renew leases on favorable terms to generate rental revenues, and dependence on our tenants' financial condition; o we may fail to identify, acquire, construct or develop additional properties; we may develop properties that do not produce a desired yield on invested capital; or we may fail to effectively integrate acquisitions of properties or portfolios of properties; o financing may not be available, or may not be available on favorable terms; o we need to make distributions to our stockholders for us to qualify as a real estate investment trust, and if we need to borrow the funds to make the distributions, borrowings may not be available on favorable terms; o we depend on the core markets where our properties are located and these markets may be adversely affected by local economic and market conditions which are beyond our control; o we are subject to potential environmental liabilities; o we are subject to complex regulations relating to our status as a real estate investment trust and would be adversely affected if we failed to qualify as a real estate investment trust; and o market interest rates could adversely affect the market prices for our common stock, as well as our performance and cash flow. We caution you that, while forward-looking statements reflect our good faith beliefs, they are not guarantees of future performance. In addition, we disclaim any obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future events or otherwise. 7 OUR COMPANY Boston Properties, Inc. We are a fully-integrated, self-administered and self-managed real estate investment trust or "REIT" and one of the largest owners and developers of office properties in the United States. We conduct substantially all our business through our affiliate, Boston Properties Limited Partnership, in which we are the sole general partner and hold a controlling economic interest. Our properties are concentrated in four core markets--Boston, midtown Manhattan, Washington, D.C. and San Francisco. We have full-service offices in Boston, New York, Washington, D.C., San Francisco and Princeton, New Jersey, and achieve efficiencies of scale by operating a centralized financial control and data center at our Boston headquarters that is responsible for operating budgets, billing and payments for all of our existing and development properties.

It may not contain all the information that is important to you. You can access complete information by referring to our certificate of incorporation, bylaws, our shareholder rights plan and the Delaware General Corporation Law. Our shareholder rights plan is summarized below. Our shareholder rights plan, certificate of incorporation and bylaws are incorporated by reference into the registration statement of which this prospectus is a part. General Under our certificate of incorporation, we have authority to issue 250,000,000 shares of common stock, par value $.01 per share. As of July 9, 2002, 95,259,251 shares of common stock were issued and outstanding. In addition, as of July 9, 2002, 20,497,784 common units of Boston Properties Limited Partnership which are exchangeable for common stock on a one-for-one basis were outstanding. We may issue common stock from time to time. Our board of directors must approve the amount of stock we sell and the price for which it is sold. Holders of our common stock do not have any preferential rights or preemptive rights to buy or subscribe for capital stock or other securities that we may issue. However, each outstanding share of our common stock currently has attached to it one preferred share purchase right issued under our shareholder rights plan, which is summarized below. Our common stock does not have any redemption or sinking fund provisions or any conversion rights. All of our common stock, when issued, will be duly authorized, fully paid and nonassessable. This means that the full price for our outstanding common stock will have been paid at the time of issuance and that any holder of our common stock will not later be required to pay us any additional money for our common stock. Dividends Subject to the preferential rights of any other shares of our stock and the provisions of our certificate of incorporation regarding excess shares, holders of our common stock may receive dividends out of assets that we can legally use to pay dividends when and if they are authorized and declared by our board of directors. Each common stockholder shares in the same proportion as other common stockholders out of assets that we can legally use to pay distributions after we pay or make adequate provision for all of our known debts and liabilities in the event we are liquidated, dissolved or our affairs are wound up. Voting rights Subject to the provisions of our certificate of incorporation regarding excess shares, holders of common stock will have the exclusive power to vote on all matters presented to our stockholders, including the election of directors, except as otherwise provided by Delaware law or as provided with respect to any other shares of our stock. Holders of our common stock are entitled to one vote per share. There is no cumulative voting in the election of our directors, which means that at any meeting of our stockholders, the holders of a majority of the outstanding common stock can elect all of the directors then standing for election. Other rights Subject to the provisions of our certificate of incorporation regarding excess shares, all shares of our common stock have equal dividend, distribution, liquidation and other rights, and have no preference, appraisal or exchange rights, except for any appraisal rights provided by Delaware law. 9 Delaware law generally requires that we obtain the approval of a majority of the outstanding shares of our common stock that are entitled to vote before we may consolidate our stock or merge with another corporation. However, Delaware law does not require that we seek approval of our stockholders to enter into a merger in which we are the surviving corporation following the merger if: o our certificate of incorporation is not amended in any respect by the merger; o each share of our stock outstanding prior to the merger is to be an identical share of stock following the merger; and o any shares of common stock (together with any other securities convertible into shares of common stock) to be issued or delivered as a result of the merger represent no more than 20% of the number of shares of our common stock outstanding immediately prior to the merger. Restrictions on ownership For us to qualify as a real estate investment trust under the Internal Revenue Code, no more than 50% in value of our outstanding stock may be owned, actually or constructively, by five or fewer individuals during the last half of a taxable year. To assist us in meeting this requirement, we may take actions including the automatic conversion of shares in excess of this ownership restriction into excess shares to limit the ownership of our outstanding equity securities, actually or constructively, by one person or entity. See "Limits on Ownership of Our Stock" beginning on page 13. Transfer agent The transfer agent and registrar for our common stock is Equiserve Trust Company, N.A. Preferred shares Under our certificate of incorporation, we have authority to issue up to 50,000,000 shares of preferred stock. We do not have any preferred stock outstanding as of the date of this prospectus. We may issue preferred stock from time to time, in one or more series, as authorized by our board of directors. Prior to issuance of shares of each series, our board of directors is required by the Delaware General Corporation Law and our certificate of incorporation to fix for each series, subject to the provisions of our certificate of incorporation regarding excess shares, the terms, preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends or other distributions, qualifications and terms or conditions of redemption, as are permitted by Delaware law. The preferred stock will, when issued, be fully paid and nonassessable and will have no preemptive rights. Our board of directors could authorize the issuance of preferred stock with terms and conditions that could have the effect of discouraging a takeover or other transaction that holders of our common stock might believe to be in their best interests or in which holders of some, or a majority, of our common stock might receive a premium for their shares over the then market price of our common stock. Under our certificate of incorporation, we have authority to issue up to 150,000,000 shares of Series E junior participating cumulative preferred stock. At July 9, 2002, none of the Series E junior participating cumulative preferred stock were issued or outstanding. Shares of our Series E junior participating cumulative preferred stock may be issued under our shareholder rights plan, which is summarized beginning on page 11. 10 Shareholder rights plan In 1997, our board of directors adopted a shareholder rights plan and entered into a shareholder rights agreement with Fleet National Bank (f.k.a. BankBoston, N.A.), as rights agent. The purpose of our shareholder rights plan is to enhance our board of directors' ability to protect our stockholders' interests by ensuring that stockholders receive fair treatment in the event that any coercive takeover attempt of Boston Properties is made in the future. The rights plan is intended to provide our board of directors with sufficient time to consider any and all alternatives to a takeover action. The rights may discourage, delay or prevent hostile takeovers. They are not intended, however, to interfere with any merger or other business combination approved by our board of directors. Under our shareholder rights plan, one preferred stock purchase right is attached to each outstanding share of our common stock. We refer to these preferred stock purchase rights as the "rights." Each share of common stock issued in the future will also receive a right until any of the rights become exercisable. Until a right is exercised, the holder of a right does not have any additional rights as a stockholder. These rights will expire on June 11, 2007, unless previously redeemed or exchanged by us as described below. These rights trade automatically with our common stock and will separate from the common stock and become exercisable only under the circumstances described below. In general, the rights will become exercisable when the first of the following events happens: 1. ten calendar days after a public announcement that a person or group has acquired beneficial ownership of 15% or more of the sum of our outstanding common stock and excess stock; or 2. ten business days, or such other date determined by our board of directors, after the beginning of a tender offer or exchange offer that would result in a person or group beneficially owning 15% or more of the sum of our outstanding common stock and excess stock. Under our shareholder rights plan, our common stock that may be issued in exchange for outstanding common units of limited partnership interest in Boston Properties Limited Partnership is not included in the definition of beneficial ownership. However, if a person who became a limited partner of Boston Properties Limited Partnership at the time of our initial public offering acquires beneficial ownership of 15% or more of the sum of our common stock and excess stock, the rights will not become exercisable unless the acquisition results in that person acquiring a greater percentage of the outstanding shares of our outstanding common stock plus outstanding common units of limited partnership interest of Boston Properties Limited Partnership than the percentage of outstanding shares of common stock plus outstanding common units of limited partnership interest of Boston Properties Limited Partnership that person held at the completion of our initial public offering. In addition, no group of which a person who became a partner of Boston Properties Limited Partnership at the time of our initial public offering is a member will be deemed to beneficially own our common stock and excess stock owned by that person. Common units of limited partnership interest of Boston Properties Limited Partnership held by Boston Properties, Inc. are excluded in making these calculations. If the rights become exercisable, holders of the rights will be able to purchase from us a unit of preferred stock equal to one ten-thousandth of a share of our Series E junior participating cumulative preferred stock at a price of $100 per unit, subject to adjustment. We have designated 200,000 shares of Series E junior participating cumulative preferred stock and have reserved these 11 shares for issuance under our shareholder rights plan. However, all rights owned by any persons or groups triggering the event shall be void. In addition, if at any time following a public announcement that a person or group has acquired beneficial ownership of 15% or more of the sum of our outstanding common stock and excess stock: o we enter into a merger or other business combination transaction in which we are not the surviving entity; o we enter into a merger or other business combination transaction in which all or part of our common stock is exchanged; or o we sell, transfer or mortgage 50% or more of our assets or earning power; then each holder of a right, other than rights held by the person or group who triggered the event, will be entitled to receive, upon exercise, common stock of the acquiring company equal to two times the purchase price of the right. At any time after our public announcement that a person or group has acquired beneficial ownership of 15% or more of the sum of our outstanding common stock and excess stock, our board of directors may, at its option, exchange all or any part of the then outstanding and exercisable rights for shares of our common stock or units of Series E junior participating cumulative preferred stock at an exchange ratio of one share or one unit per right. However, our board of directors generally will not be empowered to effect an exchange at any time after any person becomes the beneficial owner of 50% or more of our outstanding common stock. We may redeem the rights at $.001 per right at any time before the date that is ten days after a public announcement that a person or group has acquired beneficial ownership of 15% or more of the sum of our outstanding common stock and excess stock. We may extend this redemption period at any time while the rights are still redeemable. The rights will expire at the close of business on June 11, 2007 unless we redeem them before that date. The above description of our shareholder rights plan is not intended to be a complete description. For a full description of the shareholder rights plan, you should read the rights agreement. You may obtain a copy of the rights agreement at no charge by writing to us at the address listed on page 6. 12 LIMITS ON OWNERSHIP OF OUR STOCK Ownership limits For us to qualify as a real estate investment trust under the Internal Revenue Code, among other things, not more than 50% in value of our outstanding stock may be owned, actually or constructively, by five or fewer individuals during the last half of a taxable year other than the first year, and our outstanding stock must be beneficially owned by 100 or more persons during at least 335 days of a taxable year of 12 months other than the first year or during a proportionate part of a shorter taxable year. In order to protect us against the risk of losing our status as a real estate investment trust due to a concentration of ownership among our stockholders, our certificate of incorporation provides that generally no holder may beneficially own, or be deemed to own by virtue of the attribution provisions of the Internal Revenue Code, more than 6.6% of any class or series of our stock. Under our certificate of incorporation, a person generally "beneficially owns" shares if: o the person has direct ownership of the shares, o the person has indirect ownership of the shares taking into account the constructive ownership rules of Section 544 of the Internal Revenue Code, as modified by Section 856(h)(1)(B) of the Internal Revenue Code, or o the person would be deemed to beneficially own the shares pursuant to Rule 13d-3 under the Exchange Act of 1934, as amended. Our certificate of incorporation allows two exceptions to the 6.6% ownership limit: 15% Related party ownership limit: Each of Messrs. Zuckerman and E. Linde, together with their respective heirs, legatees, devisees and any other person whose beneficial ownership of our common stock would be attributed under the Internal Revenue Code to them, are subject to an ownership limit of 15% for each of them together with such persons related to them. 15% Look-through entity ownership limit: Pension plans described in Section 401(a) of the Internal Revenue Code and mutual funds registered under the Investment Company Act of 1940 are subject to an ownership limit of 15%. Pension plans and mutual funds are among the entities that are not treated as stockholders under the "five or fewer requirement." Rather, the beneficial owners of these entities will be counted as stockholders for this purpose. The foregoing restrictions will not apply if our board of directors determines that it is no longer in our best interests to attempt to qualify, or to continue to qualify, as a real estate investment trust. In addition, the foregoing restrictions do not apply with respect to an offeror in the event of an all cash tender offer by it which has been accepted by at least two-thirds of our outstanding stock. Shares in excess of ownership limits Transfers of our stock or any security convertible into our stock or other events that would create a direct or indirect ownership of our stock that would: o violate the 6.6% ownership limit; o violate the 15% ownership limit for related parties; 13 o violate the 15% ownership limit for look-through entities; or o result in our disqualification as a real estate investment trust, including any transfer that results in: o our stock being owned by fewer than 100 persons, o Boston Properties being "closely held" with the meaning of Section 856(h) of the Internal Revenue Code, or o Boston Properties constructively owning 10% or more of one of our tenants, shall be null and void and of no effect with respect to the shares in excess of the applicable limit. Any shares in excess of an applicable limitation will be converted automatically into an equal number of shares of our excess stock that will be transferred by operation of law to a trust for the benefit of a qualified charitable organization selected by us, but not affiliated with us. As soon as practicable after the transfer of shares to the trust, the trustee of the trust will be required to sell the excess shares to a person or entity who could own the shares without violating the applicable limit and distribute to the original transferee-stockholder an amount equal to the lesser of: o the proceeds of the sale, or o the price paid for our stock in excess of the applicable limit by the original transferee-owner or, in the event that the original violative transfer was a gift or an event other than a transfer, the fair market value of the excess shares on the date they are sold by the trust. All dividends and other distributions received with respect to the excess shares prior to their sale by the trust and any proceeds from the sale by the trust in excess of the amount distributable to the original transferee-owner will be distributed to the beneficiary of the trust. Right to purchase excess shares In addition to the foregoing transfer restrictions, we have the right, for a period of 90 days during the time any excess shares are held by the trust, to purchase all or any portion of the excess shares for the lesser of the price paid for the shares in excess of the applicable limit by the original transferee-stockholder or the market price of our stock on the date we exercise our option to purchase, which amount will be paid to the original transferee-stockholder. The market price will be determined in the manner set forth in our certificate of incorporation. The 90-day period begins on the date of the violative transfer if the original transferee-stockholder gives notice to us of the transfer or, if no notice is given, the date on which our board of directors determines that a violative transfer has been made. Disclosure of stock ownership by our stockholders Each of our stockholders will upon demand be required to disclose to us in writing any information with respect to the direct, indirect and constructive ownership of shares of our stock as our board of directors deems necessary to comply with the provisions of the Internal Revenue Code applicable to real estate investment trusts, to comply with the requirements of any taxing authority or governmental agency or to determine any such compliance. These ownership limitations may have the effect of precluding the acquisition of control of Boston Properties unless our board of directors determines that our maintenance of real estate investment trust status is no longer in our best interests. 14 IMPORTANT PROVISIONS OF DELAWARE LAW AND OUR CERTIFICATE OF INCORPORATION AND BYLAWS The following is a summary of important provisions of Delaware law and our certificate of incorporation and bylaws which affect us and our stockholders. The description below is intended as only a summary. You can access complete information by referring to Delaware General Corporation Law and our certificate of incorporation and bylaws. Business combinations with interested stockholders under Delaware law Section 203 of the Delaware General Corporation Law prevents a publicly held corporation from engaging in a "business combination" with an "interested stockholder" for a period of three years after the date of the transaction in which the person became an interested stockholder, unless: o before the date on which the person became an interested stockholder, the board of directors of the corporation approved either the business combination or the transaction in which the person became an interested stockholder; o the interested stockholder owned at least 85% of the outstanding voting stock of the corporation at the beginning of the transaction in which it became an interested stockholder, excluding stock held by directors who are also officers of the corporation and by employee stock plans that do not provide participants with the rights to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or o after the date on which the interested stockholder became an interested stockholder, the business combination is approved by the board of directors and the holders of two-thirds of the outstanding voting stock of the corporation voting at a meeting, excluding the voting stock owned by the interested stockholder. As defined in Section 203, an "interested stockholder" is generally a person owning 15% or more of the outstanding voting stock of the corporation. As defined in Section 203, a "business combination" includes mergers, consolidations, stock and assets sales and other transactions with the interested stockholder. The provisions of Section 203 may have the effect of delaying, deferring or preventing a change of control of Boston Properties. Amendment of our certificate of incorporation and bylaws Amendments to our certificate of incorporation must be approved by our board of directors and generally by the vote of a majority of the votes entitled to be cast at a meeting of our stockholders. However, a 75% stockholder vote is required for amendments dealing with fundamental governance provisions of our certificate of incorporation, including: o stockholder action o the powers, election of, removal of and classification of directors o limitation of liability o amendment of our certificate of incorporation 15 Unless otherwise required by law, our board of directors may amend our bylaws by a majority vote of our directors then in office. Our bylaws may also be amended by a majority stockholder vote if our board of directors recommends the approval of the amendment, and otherwise by a 75% stockholder vote. Meetings of stockholders Under our bylaws, we will hold annual meetings of our stockholders at a date and time as determined by our board of directors, Chairman or President. Our bylaws require advance notice for our stockholders to make nominations of candidates for our board of directors or bring other business before an annual meeting of our stockholders. Only our board of directors can call special meetings of our stockholders and any special meeting is restricted to considering and acting upon matters set forth in the notice of that special meeting. Board of directors Our board of directors is divided into three classes. As the term of each class expires, directors in that class will be elected for a term of three years and until their successors are duly elected and qualified. Our certificate of incorporation provides that a 75% vote of our board of directors is required to approve fundamental changes or actions, including: o a change of control of Boston Properties or of Boston Properties Limited Partnership; o any amendment to the limited partnership agreement of Boston Properties Limited Partnership; o any waiver of the limitations on ownership contained in our certificate of incorporation; o certain issuances of equity securities by Boston Properties; and o termination of our status as a REIT. Shareholder rights plan and ownership limitations We have adopted a shareholder rights agreement. In addition, our certificate of incorporation contains provisions that limit the ownership by any person of shares of any class or series of our capital stock. See "Shareholder rights plan" beginning on page 11 and "Limits on Ownership of Our Stock" beginning on page 13. Limitation of directors' and officers' liability Our certificate of incorporation generally limits the liability of our directors to Boston Properties to the fullest extent permitted by Delaware law, as it now exists or may in the future be amended. The Delaware General Corporation Law permits a corporation to indemnify its directors, officers, employees or agents and expressly provides that the indemnification provided for under the Delaware General Corporation Law shall not be deemed exclusive of any indemnification right under any bylaw, vote of stockholders or disinterested directors, or otherwise. Delaware law permits indemnification against expenses and certain other liabilities arising out of legal actions brought or threatened against these persons for their conduct on behalf of a corporation, provided that each such person acted in good faith and in a manner that he or she reasonably believed was in or not opposed to the corporation's best interests and, in the case of a criminal proceeding, provided each person had no reasonable cause to believe his or her conduct was unlawful. Delaware law does not allow indemnification of directors in the case of an action by or in the right of a corporation unless the directors successfully defend the action or indemnification is ordered by the court. 16 Our bylaws provide that our directors and officers will be, and, in the discretion of our board of directors, non-officer employees may be, indemnified by Boston Properties to the fullest extent authorized by Delaware law, as it now exists or may in the future be amended, against all expenses and liabilities actually and reasonably incurred in connection with service for or on behalf of Boston Properties. Our bylaws also provide that the right of directors and officers to indemnification shall be a contract right and shall not be exclusive of any other right now possessed or hereafter acquired under any bylaw, agreement, vote of stockholders, or otherwise. Our certificate of incorporation contains a provision permitted by Delaware law that generally eliminates the personal liability of directors for monetary damages for breaches of their fiduciary duty, including breaches involving negligence or gross negligence in business combinations, unless the director has breached his or her duty of loyalty, failed to act in good faith, engaged in intentional misconduct or a knowing violation of law, paid a dividend or approved a stock repurchase in violation of the Delaware General Corporation Law or obtained an improper personal benefit. This provision does not alter a director's liability under the federal securities laws. In addition, this provision does not affect the availability of equitable remedies, including an injunction or rescission, for breach of fiduciary duty. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers or persons controlling Boston Properties pursuant to the foregoing provisions, we have been informed that in the opinion of the staff of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is therefore unenforceable. Indemnification agreements We have entered into indemnification agreements with each of our directors and executive officers. The indemnification agreements require, among other things, that we indemnify our directors and executive officers to the fullest extent permitted by law and advance to our directors and executive officers all related expenses, subject to reimbursement if it is subsequently determined that indemnification is not permitted. Under these agreements, we must also indemnify and advance all expenses incurred by our directors and executive officers seeking to enforce their rights under the indemnification agreements and cover our directors and executive officers under our directors' and officers' liability insurance. Although the form of indemnification agreement offers substantially the same scope of coverage afforded by our certificate of incorporation and our bylaws, it provides greater assurance to our directors and executive officers that indemnification will be available, because, as a contract, it cannot be modified unilaterally in the future by our board of directors or by our stockholders to eliminate the rights it provides. 17 FEDERAL INCOME TAX CONSIDERATIONS AND CONSEQUENCES OF YOUR INVESTMENT The following is a general summary of the material federal income tax considerations and consequences associated with an investment in our common stock. The following discussion is not exhaustive of all possible tax considerations and is not tax advice. Moreover, this summary does not deal with all tax aspects or consequences that might be relevant to you in light of your personal circumstances; nor does it deal with particular types of stockholders that are subject to special treatment under the Internal Revenue Code, including insurance companies, financial institutions and broker-dealers. The Internal Revenue Code provisions governing the federal income tax treatment of real estate investment trusts are highly technical and complex, and this summary is qualified in its entirety by the applicable Internal Revenue Code provisions, rules and regulations promulgated thereunder, and administrative and judicial interpretations thereof. The following discussion is based on current law and on representations from us concerning our compliance with the requirements for qualification as a real estate investment trust. We urge you, as a prospective investor, to consult your own tax advisor with respect to the specific federal, state, local, foreign and other tax consequences to you of the purchase, holding and sale of our common stock. Federal income taxation In the opinion of our tax counsel, Goodwin Procter LLP, commencing with our first taxable year ended December 31, 1997, we have been organized in conformity with the requirements for qualification as a real estate investment trust under the Internal Revenue Code, and our method of operation will enable us to continue to meet the requirements for qualification and taxation as a real estate investment trust under the Internal Revenue Code, provided that we have operated and continue to operate in accordance with various assumptions and factual representations made by us concerning our business, properties and operations. We may not, however, have met or continue to meet these requirements. Qualification as a real estate investment trust depends upon us having met and continuing to meet the various requirements imposed under the Internal Revenue Code through actual operating results. Goodwin Procter LLP has relied on our representations regarding our operations and has not and will not review these operating results. No assurance can be given that actual operating results have met or will meet these requirements. If we have qualified and continue to qualify for taxation as a real estate investment trust, we generally will not be subject to federal corporate income taxes on that portion of our ordinary income or capital gain that is currently distributed to stockholders. The real estate investment trust provisions of the Internal Revenue Code generally allow a real estate investment trust to deduct dividends paid to its stockholders. This deduction for dividends paid to stockholders substantially eliminates the federal double taxation on earnings that usually results from investments in a corporation. "Double taxation" refers to taxation of income once at the corporate level when earned and once again at the stockholder level when distributed. Additionally, a real estate investment trust may elect to retain and pay taxes on a designated amount of its net long-term capital gains, in which case the stockholders of the real estate investment trust will include their proportionate share of the undistributed long-term capital gains in income and receive a credit or refund for their share of the tax paid by the real estate investment trust. Failure to qualify If we fail to qualify for taxation as a real estate investment trust in any taxable year and the relief provisions do not apply, we will be subject to tax on our taxable income at regular corporate rates, including any applicable alternative minimum tax. Distributions to stockholders in any year in which we fail to qualify will not be deductible by us nor will they be required to be made. In such event, to the extent of current or accumulated earnings and profits, all distributions to stockholders 18 will be dividends, taxable as ordinary income, and subject to limitations of the Internal Revenue Code, corporate distributees may be eligible for the dividends-received deduction. Unless we are entitled to relief under specific statutory provisions, we also will be disqualified from taxation as a real estate investment trust for the four taxable years following the year during which qualification was lost. It is not possible to state whether in all circumstances we would be entitled to statutory relief. For example, we must derive a minimum percent of our gross income from specified sources in order to qualify as a real estate investment trust. If we fail to satisfy these gross income tests because nonqualifying income that we intentionally incur exceeds the limit on gross income, the Internal Revenue Service could conclude that our failure to satisfy the tests was not due to reasonable cause, which is a condition to qualification for relief from the four-year disqualification rule. Taxation of United States stockholders and potential tax consequences of their investment in our common stock When we refer to a United States stockholder, we mean a holder of common stock that is for federal income tax purposes: o an individual who is a citizen or resident of the United States; o a corporation created or organized in or under the laws of the United States, any state thereof or the District of Columbia; or o a partnership, trust or estate treated as a domestic partnership, trust or estate. For any taxable year for which we qualify for taxation as a real estate investment trust, amounts distributed to taxable United States stockholders will be taxed as follows. Distributions generally. Distributions other than capital gain dividends to United States stockholders will be taxable as dividends to the extent of our current or accumulated earnings and profits as determined for federal income tax purposes. For purposes of determining whether distributions are out of current or accumulated earnings and profits, our earnings and profits will be allocated first to any of our outstanding preferred shares and then to our common stock. Dividends will be taxable to the stockholders as ordinary income and will not be eligible for the dividends-received deduction for corporations. To the extent that we make a distribution to a United States stockholder in excess of current or accumulated earnings and profits, the distribution will be treated first as a tax-free return of capital with respect to the shares, reducing the United States stockholder's tax basis in the shares, and the distribution in excess of a United States stockholder's tax basis in the shares will be taxable as gain realized from the sale of the shares. Dividends declared by us in October, November or December of any year payable to a stockholder of record on a specified date in any such month shall be treated as both paid by us and received by the stockholder on December 31 of the year, provided that the dividend is actually paid by us during January of the following calendar year. United States stockholders may not include on their own federal income tax returns any of our tax losses. Capital gain dividends. Dividends to United States stockholders that are properly designated by us as capital gain dividends will be treated as long-term capital gains, to the extent they do not exceed our actual net capital gains, for the taxable year without regard to the period for which the stockholder has held its common stock. However, corporate stockholders may be required to treat up to 20% of particular capital gain dividends as ordinary income. Capital gain dividends are not eligible for the dividends-received deduction for corporations. Retained capital gains. A real estate investment trust may elect to retain, rather than distribute, its net long-term capital gains received during the year. To the extent designated by the 19 real estate investment trust in a notice to its stockholders, the real estate investment trust will pay the income tax on these gains and the real estate investment trust stockholders must include their proportionate share of the undistributed long-term capital gains so designated in income. Each real estate investment trust stockholder will be deemed to have paid its share of the tax paid by the real estate investment trust, which will be credited or refunded to the stockholder. The basis of each stockholder's real estate investment trust shares will be increased by its proportionate amount of the undistributed long-term capital gains, net of the tax paid by the real estate investment trust, included in each stockholder's long-term capital gains. Passive activity loss and investment interest limitations. Distributions, including deemed distributions of undistributed long-term capital gains, from us and gain from the disposition of common stock will not be treated as passive activity income, and therefore stockholders may not be able to apply any passive losses against this income. Dividends from us, to the extent they do not constitute a return of capital, will generally be treated as investment income for purposes of the investment income limitation on the deductibility of investment interest. However, net capital gain from the disposition of common stock or capital gain dividends, including deemed distributions of undistributed long-term capital gains, generally will be excluded from investment income. Sale of the common stock. Upon the sale or exchange of common stock, the United States stockholder will generally recognize gain or loss equal to the difference between the amount realized on the sale and the tax basis of the common stock sold or exchanged. Assuming the shares are held as a capital asset, the gain or loss will be a long-term capital gain or loss if the shares have been held for more than one year. However, any loss recognized by a United States stockholder on the sale of common stock held for not more than six months and with respect to which capital gains were required to be included in the stockholder's income will be treated as a long-term capital loss to the extent of the amount of the capital gains so included. In general, the maximum tax rate imposed on the long-term capital gains of non-corporate taxpayers is 20%, although a 25% maximum tax rate is imposed on the portion of the gains attributable to the prior depreciation claimed in respect of depreciable real property held for more than one year to the extent the gain is not otherwise characterized as ordinary income under the "recapture" provisions of Section 1250 of the code. The Secretary of the Treasury has the authority to prescribe regulations on how the capital gains rates will apply to sales and exchanges by partnerships and REITs and of interests in partnerships and REITs. Pursuant to this authority, the Secretary of the Treasury issued regulations relating to the taxation of capital gains in the case of sales and exchanges of interests in partnerships. As of this time, the Secretary of the Treasury has not issued regulations relating to the taxation of capital gains in the case of sales or exchanges of interests in REITS. Accordingly, you are urged to consult with your tax advisors with respect to your capital gain tax liability resulting from any sale or taxable exchange by you of our common stock. Treatment of tax-exempt stockholders. Distributions, including deemed distributions of undistributed long-term capital gains, from us to a tax-exempt employee pension trust or other domestic tax-exempt stockholder generally will not constitute unrelated business taxable income unless the stockholder has borrowed to acquire or carry its common stock. However, certain qualified trusts that hold more than 10% by value of the shares of a particular real estate investment trust may be required to treat a specified percentage of these distributions, including deemed distributions of undistributed long-term capital gains, as unrelated business taxable income. Backup withholding Under the backup withholding rules, a United States stockholder may be subject to backup withholding at the rate of 30% (decreasing periodically to 28% in 2006) with respect to dividends paid on, and gross proceeds from the sale of, the common stock unless the stockholder (1) is a 20 corporation or comes within other specific exempt categories and, when required, demonstrates this fact or (2) provides a correct taxpayer identification number, certifies as to no loss of exemption from backup withholding and otherwise complies with applicable requirements of the backup withholding rules. A United States stockholder who does not provide us with its current taxpayer identification number may be subject to penalties imposed by the Commissioner of the Internal Revenue Service. Any amount paid as backup withholding will be creditable against the stockholder's income tax liability. We will report to stockholders and the Internal Revenue Service the amount of any reportable payments, including any dividends paid, and any amount withheld with respect to the common stock during the calendar year. State and local tax Boston Properties and our stockholders may be subject to state and local tax in various states and localities, including those in which we or our stockholders transact business, own property or reside. The tax treatment of us and our stockholders in these jurisdictions may differ from the federal income tax treatment described above. Consequently, as a prospective investor, you should consult your own tax advisors regarding the effect of state and local tax laws on an investment in our common stock. 21 REGISTRATION RIGHTS OF THE SELLING STOCKHOLDERS The following is a summary of the material terms and provisions of the registration rights agreements which we entered into with the selling stockholders. It may not contain all the information that is important to you. You can access complete information by referring to the agreements. Under the registration rights agreements, we are obligated to file a registration statement covering the sale by the selling stockholders of the common stock issued in connection with the agreements and we must use reasonable efforts to cause the registration statement to be declared effective by the Securities and Exchange Commission and to keep the registration statement continuously effective until the earlier of: o the date on which the selling stockholders no longer hold any common stock to which the registration rights agreements apply; or o the date on which all of the common stock to which the registration rights agreements apply held or acquired in the future by the selling stockholders has become eligible for sale under Rule 144(k) of the Securities Act of 1933. Any common stock sold by the selling stockholders pursuant to this prospectus will no longer be entitled to the benefits of the registration rights agreements. The registration rights agreements require that we bear all expenses of registering the common stock with the exception of brokerage and underwriting commissions and taxes of any kind and any legal, accounting and other expenses incurred by the selling stockholders, subject to our right to receive payments from one of the selling stockholders pursuant to a letter agreement. We also agreed to indemnify the selling stockholders and affiliated persons against all losses, claims, damages, actions, liabilities, costs and expenses arising under the securities laws in connection with the registration statement or this prospectus, subject to limitations specified in the registration rights agreements. In addition, the selling stockholders agreed to indemnify us and our directors, officers and any person who controls our company against all losses, claims, damages, actions, liabilities, costs and expenses arising under the securities laws if they result from: o written information furnished to us by the selling stockholders for use in the registration statement or this prospectus or any amendments to the registration statement or any prospectus supplements; or o the selling stockholders' failure to deliver, or cause to be delivered, this prospectus or any amendments or prospectus supplements to any purchaser of common stock covered by this prospectus from the selling stockholders through no fault of ours. 22 THE SELLING STOCKHOLDERS The following table sets forth the number of shares of common stock beneficially owned by the selling stockholders as of July 9, 2002, the number of shares of common stock covered by this prospectus and the total number of shares of common stock which the selling stockholders will beneficially own upon completion of this offering.

PLAN OF DISTRIBUTION This prospectus relates to the possible sale from time to time of up to an aggregate of 1,066,229 shares of common stock by the selling stockholders, or any of their pledgees, donees, transferees or other successors in interest. We are registering the common stock pursuant to our obligations under the registration rights agreements, but the registration of the common stock does not necessarily mean that any of the common stock will be offered or sold by the selling stockholders. The distribution of the common stock may be effected from time to time in one or more underwritten transactions at a fixed price or prices, which may be changed, or at market prices prevailing at the time of sale, at prices related to prevailing market prices or at negotiated prices. Any underwritten offering may be on a "best efforts" or a "firm commitment" basis. In connection with any underwritten offering, underwriters or agents may receive compensation in the form of discounts, concessions or commissions from the selling stockholders. Underwriters may sell the common stock to or through dealers, and these dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers for whom they may act as agents. The selling stockholders and any underwriters, dealers or agents that participate in the distribution of the common stock may be deemed to be underwriters under the Securities Act of 1933, and any profit on the sale of the common stock by them and any discounts, commissions or concessions received by any underwriters, dealers or agents might be deemed to be underwriting discounts and commissions under the Securities Act of 1933. At any time a particular offer of common stock is made by the selling stockholders, a prospectus supplement, if required, will be distributed that will, where applicable: o identify any underwriter, dealer or agent; o describe any compensation in the form of discounts, concessions, commissions or otherwise received by each underwriter, dealer or agent and in the aggregate to all underwriters, dealers and agents; o identify the amounts underwritten; o identify the nature of the underwriter's obligation to take the common stock; and o provide any other required information. The sale of common stock by the selling stockholders may also be effected by selling common stock directly to purchasers or to or through broker-dealers. In connection with any such sale, any broker-dealer may act as agent for the selling stockholders or may purchase from the selling stockholders all or a portion of the common stock as principal, and may be made pursuant to any of the methods described below. Sales may be made on the New York Stock Exchange or other exchanges on which the common stock are then traded, in the over-the-counter market, in negotiated transactions or otherwise at prices and at terms then prevailing or at prices related to the then-current market prices or at prices otherwise negotiated. 25 Common stock may also be sold in one or more of the following transactions: o block transactions in which a broker-dealer may sell all or a portion of the shares as agent but may position and resell all or a portion of the block as principal to facilitate the transaction; o purchases by any broker-dealer as principal and resale by any broker-dealer for its own account pursuant to any supplement to this prospectus; o a special offering, an exchange distribution or a secondary distribution in accordance with applicable New York Stock Exchange or other stock exchange rules; o ordinary brokerage transactions and transactions in which any broker-dealer solicits purchasers; o sales "at the market" to or through a market maker or into an existing trading market, on an exchange or otherwise, for shares; and o sales in other ways not involving market makers or established trading markets, including direct sales to purchasers. In effecting sales, broker-dealers engaged by the selling stockholders may arrange for other broker-dealers to participate. Broker-dealers will receive commissions or other compensation from the selling stockholders in amounts to be negotiated immediately prior to the sale that will not exceed those customary in the types of transactions involved. Broker-dealers may also receive compensation from purchasers of the common stock which is not expected to exceed that which is customary in the types of transactions involved. To comply with applicable state securities laws, the common stock will be sold, if necessary, in these jurisdictions only through registered or licensed brokers or dealers. In addition, common stock may not be sold in some states unless they have been registered or qualified for sale in the state or an exemption from registration or qualification requirement is available and is complied with. All expenses relating to the offering and sale of the common stock, other than commissions, discounts and fees of underwriters, broker-dealers or agents, and subject to our right to receive payments from one of the selling stockholders pursuant to a letter agreement, will be paid by us. We have agreed to indemnify the selling stockholders against some losses, claims, damages, actions, liabilities, costs and expenses, including liabilities under the Securities Act of 1933.

The expenses in connection with the issuance and distribution of the securities being registered are set forth in the following table (all amounts except the registration fee are estimated): Registration fee -- Securities and Exchange Commission...... $ 3,663.78 Accountants' fees and expenses*............................. 5,000.00 Blue Sky fees and expenses*................................. 1,500.00 Legal fees and expenses (other than Blue Sky)*.............. 7,500.00 Printing expenses*.......................................... 2,000.00 Miscellaneous............................................... 2,336.22 TOTAL....................................................... $ 22,000.00 ========= Except as noted, all expenses in connection with the issuance and distribution of the securities being offered shall be borne by Boston Properties, Inc. Expenses identified by an asterisk(*) will be borne in part by Boston Properties, Inc., but are also subject to our right to receive payments from one of the selling stockholders pursuant to a letter agreement. Item 15. Indemnification of Directors and Officers. Our certificate of incorporation and bylaws provide certain limitations on the liability of our directors and officers for monetary damages to Boston Properties. Our certificate of incorporation and bylaws obligate Boston Properties to indemnify its directors and officers, and permit Boston Properties to indemnify its employees and other agents, against certain liabilities incurred in connection with their service in such capacities. These provisions could reduce the legal remedies available to Boston Properties and our stockholders against these individuals. Our certificate of incorporation limits the liability of our directors and officers to Boston Properties to the fullest extent permitted from time to time by the Delaware General Corporation Law. The Delaware General Corporation Law permits, but does not require, a corporation to indemnify its directors, officers, employees or agents and expressly provides that the indemnification provided for under the Delaware General Corporation Law shall not be deemed exclusive of any indemnification right under any bylaw, vote of stockholders or disinterested directors, or otherwise. The Delaware General Corporation Law permits indemnification against expenses and certain other liabilities arising out of legal actions brought or threatened against such persons for their conduct on behalf of the corporation, provided that each such person acted in good faith and in a manner that he reasonably believed was in or not opposed to the corporation's best interests and in the case of a criminal proceeding, had no reasonable cause to believe his or her conduct was unlawful. The Delaware General Corporation Law does not allow indemnification of directors in the case of an action by or in the right of the corporation (including stockholder derivative suits) unless the directors successfully defend the action or indemnification is ordered by the court. Our certificate of incorporation contains a provision permitted by Delaware law that generally eliminates the personal liability of directors for monetary damages for breaches of their fiduciary duty, including breaches involving negligence or gross negligence in business combinations, unless the director has breached his or her duty of loyalty, failed to act in good faith, engaged in intentional misconduct or a knowing violation of law, paid a dividend or approved a stock repurchase in violation of the Delaware General Corporation Law or obtained an improper personal benefit. The provision does not alter a director's liability under the federal securities laws. In addition, this provision does not affect the availability of equitable remedies, such as an injunction or rescission, for breach of fiduciary duty. II-1 Our bylaws provide that our directors and officers will be, and, in the discretion of our board of directors, non-officer employees may be, indemnified by us to the fullest extent authorized by Delaware law, as it now exists or may in the future be amended, against all expenses and liabilities actually and reasonably incurred in connection with service for or on behalf of Boston Properties. Our bylaws also provide that the right of directors and officers to indemnification shall be a contract right and shall not be exclusive of any other right now possessed or hereafter acquired under any bylaw, agreement, vote of stockholders, or otherwise. We have entered into indemnification agreements with each of our directors and executive officers. The indemnification agreements require, among other matters, that we indemnify our directors and officers to the fullest extent permitted by law and advance to the directors and officers all related expenses, subject to reimbursement if it is subsequently determined that indemnification is not permitted. Under these agreements, we must also indemnify and advance all expenses incurred by directors and officers seeking to enforce their rights under the indemnification agreements and may cover directors and officers under our directors' and officers' liability insurance. Although the form of indemnification agreement offers substantially the same scope of coverage afforded by law, it provides additional assurance to directors and officers that indemnification will be available because, as a contract, it cannot be modified unilaterally in the future by our board of directors or our stockholders to eliminate the rights it provides. It is the position of the Securities and Exchange Commission that indemnification of directors and officers for liabilities under the Securities Act of 1933 is against public policy and unenforceable pursuant to Section 14 of the Securities Act of 1933.

Undertakings. (a) Boston Properties, Inc. hereby undertakes: (1) To file, during any period in which offers or sales are being made pursuant to this Registration Statement, a post-effective amendment to this Registration Statement: (i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this Registration Statement; and (iii) To include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material change to such information in this Registration Statement. provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Securities and Exchange Commission by Boston Properties pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in this Registration Statement; (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new Registration Statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (b) Boston Properties hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of Boston Properties' annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in this Registration Statement shall be deemed to be a new Registration Statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of Boston Properties pursuant to the foregoing provisions, or otherwise, Boston Properties has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by Boston Properties of expenses incurred or paid by a director, officer or controlling person of Boston Properties in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, Boston Properties will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.

Ladies and Gentlemen:

     This opinion is furnished in connection with the registration on Form S-3
(the "Registration Statement") pursuant to the Securities Act of 1933, as
amended (the "Securities Act"), of the resale of up to 1,066,229 shares (the
"Shares") of common stock, par value $.01 per share ("Common Stock"), of Boston
Properties, Inc. (the "Company") by holders thereof.

     In connection with rendering this opinion, we have examined the Amended and
Restated Certificate of Incorporation and Amended and Restated Bylaws of the
Company, each as amended to date; such records of the corporate proceedings of
the Company as we deemed material; and such other certificates, receipts,
records and documents as we considered necessary for the purposes of this
opinion. In our examination, we have assumed the genuineness of all signatures,
the legal capacity of natural persons, the authenticity of all documents
submitted to us as certified, photostatic or facsimile copies, the authenticity
of the originals of such copies and the authenticity of telephonic confirmations
of public officials and others. As to facts material to our opinion, we have
relied upon certificates or telephonic confirmations of public officials and
certificates, documents, statements and other information of the Company or
representatives or officers thereof.

     We are attorneys admitted to practice in The Commonwealth of Massachusetts.
We express no opinion concerning the laws of any jurisdictions other than the
laws of the United States of America, the laws of The Commonwealth of
Massachusetts, and the Delaware General Corporation Law (which includes
applicable provisions of the Delaware Constitution and reported judicial
decisions interpreting the Delaware General Corporation Law and the Delaware
Constitution).

     Based upon the foregoing, we are of the opinion that the Shares are validly
issued, fully paid and nonassessable.

     The foregoing assumes that all requisite steps were taken to comply with
the requirements of the Securities Act and applicable requirements of state laws
regulating the offer and sale of securities.

     We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to us with respect to this opinion
under the heading "Legal Matters" in the Prospectus which is a part of such
Registration Statement. In giving such consent, we do not thereby admit that we
are in the category of persons whose consent is required under Section 7 of the
Act.

Company shall give prompt written notice of such proposed filing to the Holders.
The notice referred to in the preceding sentence shall offer the Holders the

referred to above has been given by the Company to the Holders. Holders of
Registrable Shares shall be permitted to withdraw all or part of the Registrable
Shares from a Piggyback Registration at any time prior to the effective date of
such Piggyback Registration. If a Piggyback Registration is an underwritten
primary registration on behalf of the Company and the managing underwriter
advises the Company that the total number of Common Shares requested to be
included in such registration by the Holders and holders under similar
registration rights agreements exceeds the number of Common Shares that can be
sold in such offering without impairing the pricing or other commercial
practicality of such offering, the Company will include in such registration in
the following priority: (i) first, all Common Shares the Company proposes to
sell, (ii) second, up to the full number of applicable Common Shares requested
to be included in such registration by any holders identified in that certain
Registration Rights and Lock-Up Agreement dated June 23, 1997, as amended from
time to time, by and among the Company and such holders, and (iii) third, up to
the full number of applicable Registrable Shares requested to be included in
such registration by any Holders and any other holders under similar
registration rights agreements with the Company which, in the case of this
clause (iii), in the opinion of such managing underwriter, can be sold without
adversely affecting the price range or probability of success of such offering
(with, to the extent necessary, Registrable Shares allocated pro rata among the
Holders and such other holders on the basis of the total number of Common Shares
requested to be included in such registration by all such holders). If in
connection with any registration under this Section 3(c), the Common Shares to
be registered will be distributed by or through one or more underwriters, then
the Company will make reasonable efforts, upon the request of any Holder
requesting registration of Registrable Shares under this Section 3(c), to
arrange for such underwriters to include the Registrable Shares of such Holder
among the Common Shares to be distributed by or through such underwriters.

          (d) Notification and Distribution of Materials. The Company shall
notify each Holder of the effectiveness of any Registration Statement applicable
to the Registrable Shares of such Holder and shall furnish to each such Holder
such number of copies of the Registration Statement (including any amendments,
supplements and exhibits), the Prospectus contained therein (including each
preliminary prospectus and all related amendments and supplements) and any
documents incorporated by reference in the Registration Statement or such other
documents as such Holder may reasonably request in order to facilitate its sale
of the Registrable Shares in the manner described in the Registration Statement.

          (e) Amendments and Supplements. The Company shall prepare and file
with the SEC from time to time such amendments and supplements to the
Registration Statement and Prospectus used in connection therewith as may be
necessary to keep the Registration Statement effective and to comply with the
provisions of the Securities Act with respect to the disposition of all the
Registrable Shares until the earlier of (a) the Registration Expiration Date or
(b) the



                                       5



date on which the Registration Statement ceases to be effective in accordance
with the terms of this Section 3. Upon ten (10) business days' notice, the
Company shall file any supplement or post-effective amendment to the
Registration Statement with respect to the plan of distribution or such Holder's
ownership interests in Registrable Shares that is reasonably necessary to permit
the sale of the Holder's Registrable Shares pursuant to the Registration
Statement. The Company shall file any necessary listing applications or
amendments to the existing applications to cause the Common Shares registered
under any Registration Statement to be then listed or quoted on the primary
exchange or quotation system on which the Common Shares are then listed or
quoted.

          (f) Notice of Certain Events. The Company shall promptly notify each
applicable Holder of, and confirm in writing, the filing of the Registration
Statement or any Prospectus, amendment or supplement related thereto or any
post-effective amendment to the Registration Statement applicable to such Holder
and the effectiveness of any post-effective amendment.

     At any time when a Prospectus relating to the Registration Statement is
required to be delivered under the Securities Act by a Holder to a transferee,
the Company shall immediately notify each Holder of the happening of any event
as a result of which the Prospectus included in such Registration Statement, as
then in effect, includes an untrue statement of a material fact or omits to
state any material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading. In such event, the Company shall promptly prepare and furnish to
each applicable Holder a reasonable number of copies of a supplement to or an
amendment of such Prospectus as may be necessary so that, as thereafter
delivered to the purchasers of Registrable Shares, such Prospectus shall not
include an untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein, in
light of the circumstances under which they are made, not misleading. The
Company will, if necessary, amend the Registration Statement of which such
Prospectus is a part to reflect such amendment or supplement.

          (g) Underwritten Offerings. In the case of an underwritten offering of
Registrable Shares in which Holders will offer a number of Registrable Shares
with an aggregate offering price to the public of at least $35 million (provided
such number of shares represents at least 20 times the average daily trading
volume of Common Shares during the four weeks preceding the request by the
Holders to initiate an underwritten offering), the Company shall permit Holders
who hold a majority of all Registrable Shares held by the Holders who are
participating in such offering to select the investment banker(s) and manager(s)
who will administer such offering, subject to the approval of the Company which
will not be unreasonably withheld. In connection with any such underwritten
offering, the Company (upon ten (10) business days advance notice) will (i)
enter into underwriting and related agreements reasonably acceptable to the
Company with customary terms (including representations and warranties and
indemnification provisions, such provisions to be, to the extent customary, in
favor of the selling Holders as well as the underwriters, but which terms,
however, shall be no less favorable to the Company than the most recent
underwriting agreement entered into by the Company); (ii) to the extent not
otherwise disruptive of the Company's operations, reasonably cooperate with the
underwriter(s); (iii) provide customary closing documentation; (iv) to the
extent necessary, amend the Registration Statement; (v) to the extent not
otherwise disruptive of the Company's



                                       6



operations, provide such information and make available appropriate personnel as
may reasonably be requested by the Holders or the managing underwriters, and
(vi) to the extent not otherwise disruptive of the Company's operations, provide
such Holder and underwriters and their respective counsel and accountants, if
any, the opportunity to participate in the preparation of such Registration
Statement, provided, that (a) Company personnel will not be required to
participate in road show presentations (but, upon reasonable advance notice and
to the extent not unduly disruptive of the Company's operations, Company
personnel whose identity and office may be reasonably determined by the Company
will be available to participate in a reasonable number of conference calls) and
(b) the Company will be reimbursed by the Holders participating in the offering
(who shall be jointly and severally liable for such reimbursement) for any out
of pocket costs and expenses in connection with such cooperation to the extent
such expenses are greater than the expenses, or are not the type of expenses,
which would be borne by the Company in the case of other Registration Statements
filed hereunder (e.g., the cost of preparing glossy prospectuses with pictures
and the cost of any road show presentations in which the Company may in its sole
discretion may elect to participate).

     3. State Securities Laws. Subject to the conditions set forth in this
Agreement, the Company shall, in connection with the filing of any Registration
Statement hereunder, file such documents as may be necessary to register or
qualify the Registrable Shares under the securities or "Blue Sky" laws of such
states as any Holder may reasonably request, and the Company shall use its best
efforts to cause such filings to become effective; provided, however, that the
Company shall not be obligated to qualify as a foreign corporation to do
business under the laws of any such state in which it is not then qualified or
to file any general consent to service of process in any such state. Once
effective, the Company shall use its best efforts to keep such filings effective
until the earlier of (a) such time as all of the Registrable Shares have been
disposed of in accordance with the intended methods of disposition by the Holder
as set forth in the Registration Statement, (b) in the case of a particular
state, a Holder has notified the Company that it no longer requires an effective
filing in such state in accordance with its original request for filing or (c)
the date on which the Registration Statement ceases to be effective.

     4. Expenses. The Company shall bear all Registration Expenses incurred in
connection with the registration of the Registrable Shares pursuant to this
Agreement, except that each Holder shall be responsible for any brokerage or
underwriting commissions and taxes of any kind (including, without limitation,
transfer taxes) with respect to any disposition, sale or transfer of Registrable
Shares sold by it and for any legal, accounting and other expenses incurred by
it; provided, however, the responsibility of the Company to bear all
Registration Expenses is subject to the Company's right to receive payments from
The Winthrop Rockefeller Charitable Trust, a/k/a The Trust u/w Winthrop
Rockefeller (the "Trust") pursuant to that certain Letter Agreement dated as of
June 7, 2002 by and between the Company, the Partnership, WRTEC, Inc. and the
Trust.

     5. Indemnification by the Company. The Company agrees to indemnify each of
the Holders and their respective officers, directors, employees, agents,
representatives, fiduciaries and affiliates, and any underwriter (as defined in
the Securities Act (unless a formal underwriting agreement is entered into
between the Company and such underwriter, in which case the indemnification
provisions, if any, set forth therein shall apply), and each person or entity,
if any, that controls a Holder within the meaning of the Securities Act, and
each other person or entity,




                                       7



if any, subject to liability because of his, her or its connection with a Holder
(each, an "Indemnitee"), against any and all losses, claims, damages, actions,
liabilities, costs and expenses (including without limitation reasonable fees,
expenses and disbursements of attorneys and other professionals), joint or
several, arising out of or based upon any violation by the Company of the
Securities Act or of any rule or regulation promulgated thereunder (i)
applicable to the Company and relating to action or inaction required of the
Company in connection with any Registration Statement or Prospectus, or (ii)
upon any untrue or alleged untrue statement of material fact contained in the
Registration Statement or any Prospectus, or any omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein, in light of the circumstances under which they were
made, not misleading; provided, that the Company shall not be liable to such
Indemnitee or any person who participates as an underwriter in the offering or
sale of Registrable Shares or any other person, if any, who controls such
underwriter within the meaning of the Securities Act, in any such case to the
extent that any such loss, claim, damage, liability (or action or proceeding in
respect thereof) or expense arises out of or is based upon (a) an untrue
statement or alleged untrue statement or omission or alleged omission made in
such Registration Statement or in any such Prospectus in reliance upon and in
conformity with information regarding such Indemnitee or its plan of
distribution or ownership interests which was furnished in writing by such
person to the Company for use in connection with the Registration Statement or
the Prospectus contained therein by such Indemnitee or (b) such Holder's failure
to send or give a copy of the final, amended or supplemented prospectus
furnished to the Holder by the Company at or prior to the time such action is
required by the Securities Act to the person claiming an untrue statement or
alleged untrue statement or omission or alleged omission if such statement or
omission was corrected in such final, amended or supplemented prospectus.

     6. Covenants of Holders. Each of the Holders (severally and not jointly)
hereby agrees (a) to cooperate with the Company and to furnish to the Company
all such information concerning its plan of distribution and ownership interests
with respect to its Registrable Shares in connection with the preparation of a
Registration Statement with respect to such Holder's Registrable Shares and any
filings with any state securities commissions as the Company may reasonably
request, (b) to deliver or cause delivery of the Prospectus contained in such
Registration Statement to any purchaser of the shares covered by such
Registration Statement from the Holder and (c) to indemnify the Company, its
officers, directors, employees, agents, representatives and affiliates, and each
person, if any, who controls the Company within the meaning of the Securities
Act, and each other person, if any, subject to liability because of his
connection with the Company, against any and all losses, claims, damages,
actions, liabilities, costs and expenses (including, without limitation,
reasonable fees, expenses and disbursements of attorneys and other
professionals) arising out of or based upon (i) any untrue statement or alleged
untrue statement of material fact contained in either such Registration
Statement or the Prospectus contained therein, or any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading, if and to the extent that such statement
or omission occurs from reliance upon and in conformity with written information
regarding such Holder, its plan of distribution or its ownership interests,
which was furnished to the Company by such Holder expressly for use therein
unless such statement or omission was corrected in writing to the Company not
less than three (3) business days prior to the date of the final prospectus (as
supplemented or amended, as the case may be) or (ii) the failure by the




                                       8



Holder to deliver or cause to be delivered the Prospectus contained in such
Registration Statement (as amended or supplemented, if applicable) furnished by
the Company to the Holder to any purchaser of the shares covered by such
Registration Statement from the Holder through no fault of the Company.
Notwithstanding the provisions of this Section 6, no Holder shall be required to
pay as indemnification hereunder any amount in excess of the gross proceeds from
the sale of Common Shares by such Holder which gave rise to the incurrence of
such indemnification.

     7. Indemnification Procedures.

     Any person entitled to indemnification under this Agreement shall notify
promptly the indemnifying party in writing of the commencement of any action or
proceeding with respect to which a claim for indemnification may be made
hereunder, but the failure of any indemnified party to provide such notice shall
not relieve the indemnifying party of its obligations hereunder, except to the
extent the indemnifying party is materially prejudiced thereby and shall not
relieve the indemnifying party from any liability which it may have to any
indemnified party otherwise than hereunder. In case any action or proceeding is
brought against an indemnified party and it shall notify the indemnifying party
of the commencement thereof, the indemnifying party shall be entitled to
participate therein and, unless in the reasonable opinion of outside counsel to
the indemnified party a conflict of interest between such indemnified and
indemnifying parties may exist in respect of such claim, to assume the defense
thereof (alone or jointly with any other indemnifying party similarly notified),
to the extent that it chooses, with counsel reasonably satisfactory to such
indemnified party, and after notice from the indemnifying party to such
indemnified party that it so chooses, the indemnifying party shall not be liable
to such indemnified party for any legal or other expenses subsequently incurred
by such indemnified party in connection with the defense thereof; provided,
however, that (i) if the indemnifying party fails to take reasonable steps
necessary to defend diligently the action or proceeding within twenty (20)
business days after receiving notice from such indemnified party that the
indemnified party believes it has failed to do so; or (ii) if such indemnified
party who is a defendant in any action or proceeding which is also brought
against the indemnifying party reasonably shall have reasonably concluded, based
on the advice of counsel, that there may be one or more legal defenses available
to such indemnified party which are not available to the indemnifying party; or
(iii) if representation of both parties by the same counsel is otherwise
inappropriate under applicable standards of professional conduct, then, in any
such case, the indemnified party shall have the right to assume or continue its
own defense as set forth above (but with no more than one firm of counsel for
all indemnified parties in each jurisdiction, except to the extent any
indemnified party or parties reasonably shall have concluded, based on the
advice of counsel, that there may be legal defenses available to such party or
parties which are not available to the other indemnified parties or to the
extent representation of all indemnified parties by the same counsel is
otherwise inappropriate under applicable standards of professional conduct) and
the indemnifying party shall be liable for any expenses therefor. No
indemnifying party shall, without the written consent of the indemnified party
(which shall not be unreasonably withheld), effect the settlement or compromise
of, or consent to the entry of any judgment with respect to, any pending or (to
the knowledge of the indemnifying party) threatened action or claim in respect
of which indemnification or contribution may be sought hereunder (whether or not
the indemnified party is an actual or potential party to such action or claim)
unless such settlement, compromise or judgment (A) includes an unconditional
release of



                                       9



the indemnified party from all liability arising out of such action or claim and
(B) does not include a statement as to or an admission of fault, culpability or
a failure to act, by or on behalf of any indemnified party.

     8. Suspension of Registration Requirement; Restriction on Sales.

          (a) The Company shall promptly notify each Holder of, and confirm in
writing, the issuance by the SEC of any stop order suspending the effectiveness
of a Registration Statement with respect to such Holder's Registrable Shares or
the initiation of any proceedings for that purpose. The Company shall use its
best efforts to obtain the withdrawal of any order suspending the effectiveness
of such a Registration Statement at the earliest possible moment.

          (b) Notwithstanding anything to the contrary set forth in this
Agreement, the Company's obligation under this Agreement to cause a Registration
Statement and any filings with any state securities commission to become
effective or to amend or supplement a Registration Statement shall be suspended
in the event and during such period as unforeseen circumstances exist (including
without limitation (i) an underwritten primary offering by the Company if the
Company is advised by the underwriters that the sale of Registrable Shares under
the Registration Statement would impair the pricing or commercial practicality
of the primary offering or (ii) pending negotiations relating to, or
consummation of, a transaction or the occurrence of an event that would require
additional disclosure of material information by the Company in the Registration
Statement or such filing, as to which the Company has a bona fide business
purpose for preserving confidentiality or which renders the Company unable to
comply with SEC requirements) (such unforeseen circumstances being hereinafter
referred to as a "Suspension Event") that would make it impractical or
unadvisable to cause the Registration Statement or such filings to become
effective or to amend or supplement the Registration Statement, but such
suspension shall continue only for so long as such event or its effect is
continuing. The Company shall promptly notify the Holders of the existence and,
in the case of circumstances referred to in clause (i) of this Section 8(b),
nature of any Suspension Event, and shall promptly notify the Holders upon the
expiration of such Suspension Event.

          (c) Each holder of Registrable Shares agrees, if requested by the
Company in the case of a Company-initiated non-underwritten offering or if
requested by the managing underwriter or underwriters in a Company-initiated
underwritten offering, not to effect any public sale or distribution of any of
the securities of the Company, including a sale pursuant to Rule 144, during the
fifteen (15) day period prior to, and during the sixty (60) day period beginning
on, the date of commencement of such Company-initiated offering (such period, or
such lesser period as the Company may specify, a "Company Sale Period"), subject
to its rights under Section 3(c) hereof, and provided, that any such request
shall be made no more then two times in any twelve-month period.

          (d) Notwithstanding anything to the contrary in this Agreement, in no
event shall Suspension Events be permitted to take effect more than twice in any
twelve-month period and in no event shall Suspension Events and Company Sale
Periods be permitted to take effect for more than an aggregate of one hundred
twenty (120) days in any twelve-month period.



                                       10



     9. Black-Out Period. Each Holder agrees that, following the effectiveness
of any Registration Statement (except an issuance registration statement)
relating to Registrable Shares of such Holder, such Holder will not effect any
sales of the Registrable Shares pursuant to the Registration Statement or any
filings with any state Securities Commission at any time after such Holder has
received notice from the Company to suspend sales as a result of the occurrence
or existence of any Suspension Event or so that the Company may correct or
update the Registration Statement or such filing. During such period, the
Company will not be obligated to effect redemptions of Common Units under an
issuance registration statement. The Holder may recommence effecting sales of
the Registrable Shares pursuant to the Registration Statement or such filings,
and the Company will be obligated to resume effecting redemptions of Common
Units under an issuance registration statement, and all other obligations which
are suspended as a result of a Suspension Event shall no longer be so suspended,
following further notice to such effect from the Company, which notice shall be
given by the Company not later than five (5) business days after the conclusion
of any such Suspension Event.

     10. Additional Shares. The Company, at its option, may register, under any
Registration Statement and any filings with any state securities commissions
filed pursuant to this Agreement, any number of unissued Common Shares of the
Company or any Common Shares of the Company owned by any other shareholder or
shareholders of the Company.

     11. Contribution. If the indemnification provided for in Sections 5 and 6
is unavailable to an indemnified party with respect to any losses, claims,
damages, actions, liabilities, costs or expenses referred to therein or is
insufficient to hold the indemnified party harmless as contemplated therein,
then the indemnifying party, in lieu of indemnifying such indemnified party,
shall contribute to the amount paid or payable by such indemnified party as a
result of such losses, claims, damages, actions, liabilities, costs or expenses
in such proportion as is appropriate to reflect the relative fault of the
Company, on the one hand, and the Indemnitee, on the other hand, in connection
with the statements or omissions which resulted in such losses, claims, damages,
actions, liabilities, costs or expenses as well as any other relevant equitable
considerations. The relative fault of the Company, on the one hand, and of the
Indemnitee, on the other hand, shall be determined by reference to, among other
factors, whether the untrue or alleged untrue statement of a material fact or
omission to state a material fact relates to information supplied by the Company
or by the Indemnitee and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission;
provided, however, that in no event shall the obligation of any indemnifying
party to contribute under this Section 11 exceed the amount that such
indemnifying party would have been obligated to pay by way of indemnification if
the indemnification provided for under Sections 5 or 6 hereof had been available
under the circumstances.

     The Company and the Holders agree that it would not be just and equitable
if contribution pursuant to this Section 11 were determined by pro rata
allocation or by any other method of allocation that does not take account of
the equitable considerations referred to in the immediately preceding paragraph.

     Notwithstanding the provisions of this Section 11, no Holder shall be
required to contribute any amount in excess of the amount by which the gross
proceeds from the sale of Registrable Shares exceeds the amount of any damages
that the Holder has otherwise been



                                       11



required to pay by reason of such untrue or alleged untrue statement or
omission. No indemnified party guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any indemnifying party who was not guilty of such fraudulent
misrepresentation.

     12. Amendments and Waivers. The provisions of this Agreement may not be
amended, modified, or supplemented or waived without the prior written consent
of the Company and Holders holding in excess of one-half of the aggregate of all
Registrable Shares held by such Holders, provided, however, that the Company
shall amend this Agreement to the extent of combining the conversion notices
executed by the Series A Holders attached hereto and the redemption notices
executed by the Preferred Unit Holders attached hereto into Schedule A to this
Agreement listing the name of each Holder and the number of Common Shares held
by such Holder.

     13. Notices. Except as set forth below, all notices and other
communications provided for or permitted hereunder shall be in writing and shall
be deemed to have been duly given if delivered personally or sent by registered

contained herein, or the application thereof in any circumstances, is held
invalid, illegal or unenforceable in any respect for any reason, the validity,
legality and enforceability of any such provision in every other respect and of
the remaining provisions contained herein shall not be in any way impaired
thereby, it being intended that all of the rights and privileges of the parties
hereto shall be enforceable to the fullest extent permitted by law.

the subject matter contained herein. There are no restrictions, promises,
warranties or undertakings, other than those set forth or referred to herein,
with respect to such subject matter. This Agreement supersedes all prior
agreements and understandings between the parties with respect to such subject
matter.

under the Securities Act relating to the resale by each Holder of all
Registrable Shares of such Holder, and shall use reasonable best efforts to
cause such Registration Statement to be declared effective by the SEC as soon as
practicable thereafter. The Company agrees to use reasonable best efforts to
keep the Registration Statement, after its date of effectiveness, continuously
effective until the earlier of (i) the date on which all Registrable Shares have
been disposed of by the Holders or (ii) the date on which all Registrable Shares

          (b) Demand Registration. Subject to the conditions set forth in this
Agreement, at any time after the Registration Expiration Date and while any
Registrable Shares are outstanding, the Company shall, at the written request of
any Holder holding Registrable Shares, cause to be filed within twenty (20)
business days after the date of such request by such Holder a Registration
Statement under Rule 415 under the Securities Act relating to the sale by the
Holder of all of the Registrable Shares held by such Holder in accordance with
the terms hereof, and shall use reasonable best efforts to cause such
Registration Statement to be declared effective by the SEC as soon as

the Registration Statement before receipt of notice from any Holder. The Company
agrees to use reasonable efforts to keep the Registration Statement continuously
effective, after its date of effectiveness, until the date on which such Holder
no longer holds any Registrable Shares.

          (c) Piggyback Registration. If at any time while any Registrable
Shares of a Holder are outstanding and a Registration Statement applicable to
such Holders is not effective, and the Company proposes to file a registration
statement under the Securities Act with respect to an offering solely of Common
Shares solely for cash (other than a registration statement (i) on Form S-8 or
any successor form to such Form or in connection with any employee or director
welfare, benefit or compensation plan, (ii) on Form S-4 or any successor form to
such Form or in connection with an exchange offer, (iii) in connection with a
rights offering exclusively to existing holders of Common Shares, (iv) in
connection with an offering solely to employees of the Company or its
subsidiaries, or (v) relating to a transaction pursuant to Rule 145 of the
Securities Act), for its own account or for the accounts of other Holders, the
Company shall give prompt written notice of such proposed filing to the Holders.
The notice referred to in the preceding sentence shall offer the Holders the
opportunity to register such amount of Registrable


                                       23



Shares as each Holder may request (a "Piggyback Registration"). Subject to the
provisions of Section 4 below, the Company shall include in such Piggyback
Registration, in the registration and qualification for sale under the blue sky
or securities laws of the various states and in any underwriting in connection
therewith all Registrable Shares for which the Company has received written
requests for inclusion therein from Holders within twenty (20) calendar days
after the notice referred to above has been given by the Company to the Holders.
Holders of Registrable Shares shall be permitted to withdraw all or part of the
Registrable Shares from a Piggyback Registration at any time prior to the
effective date of such Piggyback Registration. If a Piggyback Registration is an
underwritten primary registration on behalf of the Company and the managing
underwriter advises the Company that the total number of Common Shares requested
to be included in such registration by the Holders and holders under similar
registration rights agreements exceeds the number of Common Shares that can be
sold in such offering without impairing the pricing or other commercial
practicality of such offering, the Company will include in such registration in
the following priority: (i) first, all Common Shares the Company proposes to
sell, (ii) second, up to the full number of applicable Common Shares requested
to be included in such registration by any holders identified in that certain
Registration Rights and Lock-Up Agreement dated June 23, 1997, as amended from
time to time, by and among the Company and such holders, and (iii) third, up to
the full number of applicable Registrable Shares requested to be included in
such registration by any Holders and any other holders under similar
registration rights agreements with the Company which, in the case of this
clause (iii), in the opinion of such managing underwriter, can be sold without
adversely affecting the price range or probability of success of such offering
(with, to the extent necessary, Registrable Shares allocated pro rata among the
Holders and such other holders on the basis of the total number of Common Shares
requested to be included in such registration by all such holders). If in
connection with any registration under this Section 3(c), the Common Shares to
be registered will be distributed by or through one or more underwriters, then
the Company will make reasonable efforts, upon the request of any Holder
requesting registration of Registrable Shares under this Section 3(c), to
arrange for such underwriters to include the Registrable Shares of such Holder
among the Common Shares to be distributed by or through such underwriters.

          (d) Notification and Distribution of Materials. The Company shall
notify each Holder of the effectiveness of any Registration Statement applicable
to the Registrable Shares of such Holder and shall furnish to each such Holder
such number of copies of the Registration Statement (including any amendments,
supplements and exhibits), the Prospectus contained therein (including each
preliminary prospectus and all related amendments and supplements) and any
documents incorporated by reference in the Registration Statement or such other
documents as such Holder may reasonably request in order to facilitate its sale
of the Registrable Shares in the manner described in the Registration Statement.

          (e) Amendments and Supplements. The Company shall prepare and file
with the SEC from time to time such amendments and supplements to the
Registration Statement and Prospectus used in connection therewith as may be
necessary to keep the Registration Statement effective and to comply with the
provisions of the Securities Act with respect to the disposition of all the
Registrable Shares until the earlier of (a) the Registration Expiration Date or
(b) the date on which the Registration Statement ceases to be effective in
accordance with the terms of this Section 3. Upon ten (10) business days'
notice, the Company shall file any supplement or post-effective amendment to the
Registration Statement with respect to the plan of distribution or


                                       24



such Holder's ownership interests in Registrable Shares that is reasonably
necessary to permit the sale of the Holder's Registrable Shares pursuant to the
Registration Statement. The Company shall file any necessary listing
applications or amendments to the existing applications to cause the Common
Shares registered under any Registration Statement to be then listed or quoted
on the primary exchange or quotation system on which the Common Shares are then
listed or quoted.

          (f) Notice of Certain Events. The Company shall promptly notify each
applicable Holder of, and confirm in writing, the filing of the Registration
Statement or any Prospectus, amendment or supplement related thereto or any
post-effective amendment to the Registration Statement applicable to such Holder
and the effectiveness of any post-effective amendment.

     At any time when a Prospectus relating to the Registration Statement is
required to be delivered under the Securities Act by a Holder to a transferee,
the Company shall immediately notify each Holder of the happening of any event
as a result of which the Prospectus included in such Registration Statement, as
then in effect, includes an untrue statement of a material fact or omits to
state any material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading. In such event, the Company shall promptly prepare and furnish to
each applicable Holder a reasonable number of copies of a supplement to or an
amendment of such Prospectus as may be necessary so that, as thereafter
delivered to the purchasers of Registrable Shares, such Prospectus shall not
include an untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein, in
light of the circumstances under which they are made, not misleading. The
Company will, if necessary, amend the Registration Statement of which such
Prospectus is a part to reflect such amendment or supplement.

          (g) Underwritten Offerings. In the case of an underwritten offering of
Registrable Shares in which Holders will offer a number of Registrable Shares
with an aggregate offering price to the public of at least $35 million (provided
such number of shares represents at least 20 times the average daily trading
volume of Common Shares during the four weeks preceding the request by the
Holders to initiate an underwritten offering), the Company shall permit Holders
who hold a majority of all Registrable Shares held by the Holders who are
participating in such offering to select the investment banker(s) and manager(s)
who will administer such offering, subject to the approval of the Company which
will not be unreasonably withheld. In connection with any such underwritten
offering, the Company (upon ten (10) business days advance notice) will (i)
enter into underwriting and related agreements reasonably acceptable to the
Company with customary terms (including representations and warranties and
indemnification provisions, such provisions to be, to the extent customary, in
favor of the selling Holders as well as the underwriters, but which terms,
however, shall be no less favorable to the Company than the most recent
underwriting agreement entered into by the Company); (ii) to the extent not
otherwise disruptive of the Company's operations, reasonably cooperate with the
underwriter(s); (iii) provide customary closing documentation; (iv) to the
extent necessary, amend the Registration Statement; (v) to the extent not
otherwise disruptive of the Company's operations, provide such information and
make available appropriate personnel as may reasonably be requested by the
Holders or the managing underwriters, and (vi) to the extent not otherwise
disruptive of the Company's operations, provide such Holder and underwriters and


                                       25



their respective counsel and accountants, if any, the opportunity to participate
in the preparation of such Registration Statement, provided, that (a) Company
personnel will not be required to participate in road show presentations (but,
upon reasonable advance notice and to the extent not unduly disruptive of the
Company's operations, Company personnel whose identity and office may be
reasonably determined by the Company will be available to participate in a
reasonable number of conference calls) and (b) the Company will be reimbursed by
the Holders participating in the offering (who shall be jointly and severally
liable for such reimbursement) for any out of pocket costs and expenses in
connection with such cooperation to the extent such expenses are greater than
the expenses, or are not the type of expenses, which would be borne by the
Company in the case of other Registration Statements filed hereunder (e.g., the
cost of preparing glossy prospectuses with pictures and the cost of any road
show presentations in which the Company may in its sole discretion may elect to
participate).

     21. State Securities Laws. Subject to the conditions set forth in this
Agreement, the Company shall, in connection with the filing of any Registration
Statement hereunder, file such documents as may be necessary to register or
qualify the Registrable Shares under the securities or "Blue Sky" laws of such
states as any Holder may reasonably request, and the Company shall use its best
efforts to cause such filings to become effective; provided, however, that the
Company shall not be obligated to qualify as a foreign corporation to do
business under the laws of any such state in which it is not then qualified or
to file any general consent to service of process in any such state. Once
effective, the Company shall use its best efforts to keep such filings effective
until the earlier of (a) such time as all of the Registrable Shares have been
disposed of in accordance with the intended methods of disposition by the Holder
as set forth in the Registration Statement, (b) in the case of a particular
state, a Holder has notified the Company that it no longer requires an effective
filing in such state in accordance with its original request for filing or (c)
the date on which the Registration Statement ceases to be effective.

     22. Expenses. The Company shall bear all Registration Expenses incurred in
connection with the registration of the Registrable Shares pursuant to this
Agreement, except that each Holder shall be responsible for any brokerage or
underwriting commissions and taxes of any kind (including, without limitation,
transfer taxes) with respect to any disposition, sale or transfer of Registrable
Shares sold by it and for any legal, accounting and other expenses incurred by
it.

     23. Indemnification by the Company. The Company agrees to indemnify each of
the Holders and their respective officers, directors, employees, agents,
representatives, fiduciaries and affiliates, and any underwriter (as defined in
the Securities Act (unless a formal underwriting agreement is entered into
between the Company and such underwriter, in which case the indemnification
provisions, if any, set forth therein shall apply), and each person or entity,
if any, that controls a Holder within the meaning of the Securities Act, and
each other person or entity, if any, subject to liability because of his, her or
its connection with a Holder (each, an "Indemnitee"), against any and all
losses, claims, damages, actions, liabilities, costs and expenses (including
without limitation reasonable fees, expenses and disbursements of attorneys and
other professionals), joint or several, arising out of or based upon any
violation by the Company of the Securities Act or of any rule or regulation
promulgated thereunder (i) applicable to the Company and relating to action or
inaction required of the Company in connection with any Registration Statement
or Prospectus, or (ii) upon any untrue or alleged untrue statement of


                                       26



material fact contained in the Registration Statement or any Prospectus, or any
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading; provided, that the
Company shall not be liable to such Indemnitee or any person who participates as
an underwriter in the offering or sale of Registrable Shares or any other
person, if any, who controls such underwriter within the meaning of the
Securities Act, in any such case to the extent that any such loss, claim,
damage, liability (or action or proceeding in respect thereof) or expense arises
out of or is based upon (a) an untrue statement or alleged untrue statement or
omission or alleged omission made in such Registration Statement or in any such
Prospectus in reliance upon and in conformity with information regarding such
Indemnitee or its plan of distribution or ownership interests which was
furnished in writing by such person to the Company for use in connection with
the Registration Statement or the Prospectus contained therein by such
Indemnitee or (b) such Holder's failure to send or give a copy of the final,
amended or supplemented prospectus furnished to the Holder by the Company at or
prior to the time such action is required by the Securities Act to the person
claiming an untrue statement or alleged untrue statement or omission or alleged
omission if such statement or omission was corrected in such final, amended or
supplemented prospectus.

     24. Covenants of Holders. Each of the Holders (severally and not jointly)
hereby agrees (a) to cooperate with the Company and to furnish to the Company
all such information concerning its plan of distribution and ownership interests
with respect to its Registrable Shares in connection with the preparation of a
Registration Statement with respect to such Holder's Registrable Shares and any
filings with any state securities commissions as the Company may reasonably
request, (b) to deliver or cause delivery of the Prospectus contained in such
Registration Statement to any purchaser of the shares covered by such
Registration Statement from the Holder and (c) to indemnify the Company, its
officers, directors, employees, agents, representatives and affiliates, and each
person, if any, who controls the Company within the meaning of the Securities
Act, and each other person, if any, subject to liability because of his
connection with the Company, against any and all losses, claims, damages,
actions, liabilities, costs and expenses (including, without limitation,
reasonable fees, expenses and disbursements of attorneys and other
professionals) arising out of or based upon (i) any untrue statement or alleged
untrue statement of material fact contained in either such Registration
Statement or the Prospectus contained therein, or any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading, if and to the extent that such statement
or omission occurs from reliance upon and in conformity with written information
regarding such Holder, its plan of distribution or its ownership interests,
which was furnished to the Company by such Holder expressly for use therein
unless such statement or omission was corrected in writing to the Company not
less than three (3) business days prior to the date of the final prospectus (as
supplemented or amended, as the case may be) or (ii) the failure by the Holder
to deliver or cause to be delivered the Prospectus contained in such
Registration Statement (as amended or supplemented, if applicable) furnished by
the Company to the Holder to any purchaser of the shares covered by such
Registration Statement from the Holder through no fault of the Company.
Notwithstanding the provisions of this Section 6, no Holder shall be required to
pay as indemnification hereunder any amount in excess of the gross proceeds from
the sale of Common Shares by such Holder which gave rise to the incurrence of
such indemnification.


                                       27



     25. Indemnification Procedures.

     Any person entitled to indemnification under this Agreement shall notify
promptly the indemnifying party in writing of the commencement of any action or
proceeding with respect to which a claim for indemnification may be made
hereunder, but the failure of any indemnified party to provide such notice shall
not relieve the indemnifying party of its obligations hereunder, except to the
extent the indemnifying party is materially prejudiced thereby and shall not
relieve the indemnifying party from any liability which it may have to any
indemnified party otherwise than hereunder. In case any action or proceeding is
brought against an indemnified party and it shall notify the indemnifying party
of the commencement thereof, the indemnifying party shall be entitled to
participate therein and, unless in the reasonable opinion of outside counsel to
the indemnified party a conflict of interest between such indemnified and
indemnifying parties may exist in respect of such claim, to assume the defense
thereof (alone or jointly with any other indemnifying party similarly notified),
to the extent that it chooses, with counsel reasonably satisfactory to such
indemnified party, and after notice from the indemnifying party to such
indemnified party that it so chooses, the indemnifying party shall not be liable
to such indemnified party for any legal or other expenses subsequently incurred
by such indemnified party in connection with the defense thereof; provided,
however, that (i) if the indemnifying party fails to take reasonable steps
necessary to defend diligently the action or proceeding within twenty (20)
business days after receiving notice from such indemnified party that the
indemnified party believes it has failed to do so; or (ii) if such indemnified
party who is a defendant in any action or proceeding which is also brought
against the indemnifying party reasonably shall have reasonably concluded, based
on the advice of counsel, that there may be one or more legal defenses available
to such indemnified party which are not available to the indemnifying party; or
(iii) if representation of both parties by the same counsel is otherwise
inappropriate under applicable standards of professional conduct, then, in any
such case, the indemnified party shall have the right to assume or continue its
own defense as set forth above (but with no more than one firm of counsel for
all indemnified parties in each jurisdiction, except to the extent any
indemnified party or parties reasonably shall have concluded, based on the
advice of counsel, that there may be legal defenses available to such party or
parties which are not available to the other indemnified parties or to the
extent representation of all indemnified parties by the same counsel is
otherwise inappropriate under applicable standards of professional conduct) and
the indemnifying party shall be liable for any expenses therefor. No
indemnifying party shall, without the written consent of the indemnified party
(which shall not be unreasonably withheld), effect the settlement or compromise
of, or consent to the entry of any judgment with respect to, any pending or (to
the knowledge of the indemnifying party) threatened action or claim in respect
of which indemnification or contribution may be sought hereunder (whether or not
the indemnified party is an actual or potential party to such action or claim)
unless such settlement, compromise or judgment (A) includes an unconditional
release of the indemnified party from all liability arising out of such action
or claim and (B) does not include a statement as to or an admission of fault,
culpability or a failure to act, by or on behalf of any indemnified party.

     26. Suspension of Registration Requirement; Restriction on Sales.

          (a) The Company shall promptly notify each Holder of, and confirm in
writing, the issuance by the SEC of any stop order suspending the effectiveness
of a Registration


                                       28



Statement with respect to such Holder's Registrable Shares or the initiation of
any proceedings for that purpose. The Company shall use its best efforts to
obtain the withdrawal of any order suspending the effectiveness of such a
Registration Statement at the earliest possible moment.

          (b) Notwithstanding anything to the contrary set forth in this
Agreement, the Company's obligation under this Agreement to cause a Registration
Statement and any filings with any state securities commission to become
effective or to amend or supplement a Registration Statement shall be suspended
in the event and during such period as unforeseen circumstances exist (including
without limitation (i) an underwritten primary offering by the Company if the
Company is advised by the underwriters that the sale of Registrable Shares under
the Registration Statement would impair the pricing or commercial practicality
of the primary offering or (ii) pending negotiations relating to, or
consummation of, a transaction or the occurrence of an event that would require
additional disclosure of material information by the Company in the Registration
Statement or such filing, as to which the Company has a bona fide business
purpose for preserving confidentiality or which renders the Company unable to
comply with SEC requirements) (such unforeseen circumstances being hereinafter
referred to as a "Suspension Event") that would make it impractical or
unadvisable to cause the Registration Statement or such filings to become
effective or to amend or supplement the Registration Statement, but such
suspension shall continue only for so long as such event or its effect is
continuing. The Company shall promptly notify the Holders of the existence and,
in the case of circumstances referred to in clause (i) of this Section 8(b),
nature of any Suspension Event, and shall promptly notify the Holders upon the
expiration of such Suspension Event.

          (c) Each holder of Registrable Shares agrees, if requested by the
Company in the case of a Company-initiated non-underwritten offering or if
requested by the managing underwriter or underwriters in a Company-initiated
underwritten offering, not to effect any public sale or distribution of any of
the securities of the Company, including a sale pursuant to Rule 144, during the
fifteen (15) day period prior to, and during the sixty (60) day period beginning
on, the date of commencement of such Company-initiated offering (such period, or
such lesser period as the Company may specify, a "Company Sale Period"), subject
to its rights under Section 3(c) hereof, and provided, that any such request
shall be made no more then two times in any twelve-month period.

          (d) Notwithstanding anything to the contrary in this Agreement, in no
event shall Suspension Events be permitted to take effect more than twice in any
twelve-month period and in no event shall Suspension Events and Company Sale
Periods be permitted to take effect for more than an aggregate of seventy-five
(75) days in any twelve-month period.

     27. Black-Out Period. Each Holder agrees that, following the effectiveness
of any Registration Statement (except an issuance registration statement)
relating to Registrable Shares of such Holder, such Holder will not effect any
sales of the Registrable Shares pursuant to the Registration Statement or any
filings with any state Securities Commission at any time after such Holder has
received notice from the Company to suspend sales as a result of the occurrence
or existence of any Suspension Event or so that the Company may correct or
update the Registration Statement or such filing. During such period, the
Company will not be obligated to effect redemptions of Common Units under an
issuance registration statement. The Holder may recommence effecting sales of
the Registrable Shares pursuant to the Registration Statement or


                                       29



such filings, and the Company will be obligated to resume effecting redemptions
of Common Units under an issuance registration statement, and all other
obligations which are suspended as a result of a Suspension Event shall no
longer be so suspended, following further notice to such effect from the
Company, which notice shall be given by the Company not later than five (5)
business days after the conclusion of any such Suspension Event.

     28. Additional Shares. The Company, at its option, may register, under any
Registration Statement and any filings with any state securities commissions
filed pursuant to this Agreement, any number of unissued Common Shares of the
Company or any Common Shares of the Company owned by any other shareholder or
shareholders of the Company.

     29. Contribution. If the indemnification provided for in Sections 5 and 6
is unavailable to an indemnified party with respect to any losses, claims,
damages, actions, liabilities, costs or expenses referred to therein or is
insufficient to hold the indemnified party harmless as contemplated therein,
then the indemnifying party, in lieu of indemnifying such indemnified party,
shall contribute to the amount paid or payable by such indemnified party as a
result of such losses, claims, damages, actions, liabilities, costs or expenses
in such proportion as is appropriate to reflect the relative fault of the
Company, on the one hand, and the Indemnitee, on the other hand, in connection
with the statements or omissions which resulted in such losses, claims, damages,
actions, liabilities, costs or expenses as well as any other relevant equitable
considerations. The relative fault of the Company, on the one hand, and of the
Indemnitee, on the other hand, shall be determined by reference to, among other
factors, whether the untrue or alleged untrue statement of a material fact or
omission to state a material fact relates to information supplied by the Company
or by the Indemnitee and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission;
provided, however, that in no event shall the obligation of any indemnifying
party to contribute under this Section 11 exceed the amount that such
indemnifying party would have been obligated to pay by way of indemnification if
the indemnification provided for under Sections 5 or 6 hereof had been available
under the circumstances.

     The Company and the Holders agree that it would not be just and equitable
if contribution pursuant to this Section 11 were determined by pro rata
allocation or by any other method of allocation that does not take account of
the equitable considerations referred to in the immediately preceding paragraph.

     Notwithstanding the provisions of this Section 11, no Holder shall be
required to contribute any amount in excess of the amount by which the gross
proceeds from the sale of Registrable Shares exceeds the amount of any damages
that the Holder has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission. No indemnified party guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any indemnifying party who was not guilty
of such fraudulent misrepresentation.

     30. Amendments and Waivers. The provisions of this Agreement may not be
amended, modified, or supplemented or waived without the prior written consent
of the Company and Holders holding in excess of one-half of the aggregate of all
Registrable Shares held by such Holders, provided, however, that the Company
shall amend this Agreement to the







                                       30



extent of combining the conversion notices executed by the Series A Holders
attached hereto and the redemption notices executed by the Holders attached
hereto into Schedule A to this Agreement listing the name of each Holder and the
number of Common Shares held by such Holder.

     31. Notices. Except as set forth below, all notices and other
communications provided for or permitted hereunder shall be in writing and shall
be deemed to have been duly given if delivered personally or sent by registered

     35. Severability. In the event that any one or more of the provisions
contained herein, or the application thereof in any circumstances, is held
invalid, illegal or unenforceable in any respect for any reason, the validity,
legality and enforceability of any such provision in every other respect and of

thereby, it being intended that all of the rights and privileges of the parties
hereto shall be enforceable to the fullest extent permitted by law.
