Item 8.01. Other Events.

On June 30, 1998, Boston Properties, Inc. (the “Company”) acquired from entities controlled by Mr. Alan B. Landis a portfolio of properties known as the Carnegie Center Portfolio and related operations in Princeton, New Jersey, for approximately $276.0 million in total consideration, consisting of $137.0 million in cash, the assumption of $64.0 million of debt and the issuance of Series One Preferred Units of limited partnership interest in Boston Properties Limited Partnership (the “Operating Partnership”) having an aggregate liquidation preference of approximately $83.0 million. The Series One Preferred Units were convertible into common units of limited partnership interest in the Operating Partnership (“Common Units”) at $38.25 per Common Unit and have all been converted into Common Units. Under the agreement to acquire the Carnegie Center Portfolio, the Company also obtained the right to acquire three additional Class A buildings located in the Carnegie Center office complex, which were acquired on March 1, 2000 through the assumption of approximately $49.0 million of mortgage financing and the issuance of an aggregate of 577,817 Common Units. Currently, Mr. Landis owns, directly or indirectly through his affiliates, 1,551,255 Common Units.

In connection with the acquisition of the Carnegie Center Portfolio, Mr. Landis became a director of the Company pursuant to an Agreement Regarding Directorship, dated as of June 30, 1998, with the Company (the “Directorship Agreement”). Under the Directorship Agreement, the Company agreed to nominate Mr. Landis for re-election as a director at each annual meeting of stockholders of the Company in a year in which his term expires, provided that specified conditions are met. Mr. Landis remains a director of the Company, although he does not qualify as an independent director for purposes of the New York Stock Exchange corporate governance rules.

Additionally, in connection with the acquisition of the Carnegie Center Portfolio, the Operating Partnership entered into a development agreement with an affiliate of Mr. Landis providing for up to approximately 2,000,000 square feet of development in or adjacent to the Carnegie Center office complex (the “Development Agreement”). Under the Development Agreement, an affiliate of Mr. Landis agreed to, for a period of twenty years ending June 30, 2018, give the Operating Partnership rights to acquire and develop the land subject to the Development Agreement and restrict the ability of the affiliate of Mr. Landis to otherwise sell this land to third parties. Generally, for each land parcel that the Operating Partnership may choose to acquire under the Development Agreement, affiliates of Mr. Landis were entitled to receive $20 per rentable square foot of property developed and, if stabilized returns for the property exceeded established target annual returns, additional payments based on the stabilized returns. The Development Agreement also provided that prior to the development of a land parcel, the land parcel would be acquired by an entity controlled by the Operating Partnership and in which Mr. Landis or an affiliate of Mr. Landis would have an interest and, upon negotiated terms and conditions, the Operating Partnership and an affiliate of Mr. Landis would form a development company to provide development services for projects under the Development Agreement. For the development services, the entity that acquired the land parcel was to pay the development company a total fee of $5.00 per rentable square foot actually constructed. Revenues and expenses of the development company were to be shared equally by the

Operating Partnership and the affiliate of Mr. Landis. Also, pursuant to the Development Agreement, Mr. Landis, personally, had the right to receive compensation from the development company at a rate of $250,000 per year so long as he continued to play a meaningful role in development activities. Through the date of this report, Mr. Landis has not received any such compensation.

In the past few years, the Operating Partnership and Mr. Landis have been unable to agree on terms of ancillary documents that were to be entered into under the Development Agreement and, on October 21, 2004, entered into an Agreement to modify several provisions of the Development Agreement (the “2004 Agreement”). Under the terms of the 2004 Agreement, the Operating Partnership and affiliates of Mr. Landis amended the Development Agreement to limit the rights of Mr. Landis and his affiliates to participate in the development of properties under the Development Agreement. Among other things, Mr. Landis has agreed that (1) Mr. Landis and his affiliates will have no right to participate in any entity formed to acquire land parcels or the development company formed by the Operating Partnership to provide development services under the Development Agreement, (2) Mr. Landis will have no right or obligation to play a role in development activities engaged in by the development company formed by the Operating Partnership under the Development Agreement or receive compensation from the development company and (3) the affiliate of Mr. Landis will have no right to receive a contingent payment for developed properties based on stabilized returns. In exchange, the Company (together with the Operating Partnership) has agreed to:

•

effective as of June 30, 1998, pay Mr. Landis $125,000 on January 1 of each year until the earlier of (A) January 1, 2018, (B) the termination of the Development Agreement or (C) the date on which all development properties under the Development Agreement have been conveyed pursuant to the Development Agreement, with $750,000, representing payments of this annual amount from 1998 to 2004, being paid currently; and

•

pay an affiliate of Mr. Landis, in connection with the development of land parcels acquired under the Development Agreement, an aggregate fixed amount of $10.50 per rentable square foot of property developed (with a portion of this amount (i.e., $5.50) being subject to adjustment, in specified circumstances, based on future increases in the Consumer Price Index) in lieu of a contingent payment based on stabilized returns, which payment could have been greater or less than $10.50 per rentable square foot of property developed.

The Operating Partnership also continues to be obligated to pay an affiliate of Mr. Landis the purchase price of $20 per rentable square foot of property developed for each land parcel acquired as provided in the original Development Agreement. During the 20-year term of the Development Agreement, until such time, if any, as the Operating Partnership elects to acquire a land parcel, an affiliate of Mr. Landis will remain responsible for all carrying costs associated with such land parcel.

In addition, in connection with entering into the 2004 Agreement, Mr. Landis has resigned as a director of the Company, effective as of the earlier of (i) immediately prior to the Company’s 2005 annual meeting of stockholders and (ii) May 11, 2005, and has agreed that the Company will have no future obligation to nominate Mr. Landis as a director of the Company under the Directorship Agreement or otherwise. The scheduled effective date of Mr. Landis’s resignation will afford the Board with time, prior to the next annual stockholders meeting, to review its size and overall

composition and evaluate whether it would be appropriate to identify possible candidates for nomination as a new independent director to fill the vacancy created by Mr. Landis’s resignation. Mr. Landis did not resign because of a disagreement with the Company on any matter relating to the Company’s operations, policies or practices.

EXHIBIT A

FIRST AMENDMENT TO DEVELOPMENT AGREEMENT

THIS FIRST AMENDMENT TO DEVELOPMENT AGREEMENT (this “First Amendment”) is made and entered into as of October 21, 2004 between PRINCETON LAND PARTNERS, L.L.C., a Delaware limited liability company (“Owner”), ABL CAPITAL CORP., a New Jersey corporation (“ABL”), and BOSTON PROPERTIES LIMITED PARTNERSHIP, a Delaware limited partnership (“BPLP”). As used herein, ABL and Owner are collectively referred to as “Landis.”

RECITALS

A. Landis and BPLP entered into that certain Development Agreement dated as of June 30, 1998 (the “Development Agreement”) a true, correct and complete copy of which is attached hereto as Exhibit A; and

B. Landis and BPLP desire to amend the Development Agreement to reflect certain agreements among the parties as more particularly set forth herein.

NOW, THEREFORE, in consideration of the premises and mutual covenants, agreements and conditions hereof and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Landis and BPLP agree as follows:

D/M Company. Notwithstanding anything to the contrary contained in the Development Agreement, effective as of June 30, 1998, the D/M Company shall mean a Delaware limited liability company whose sole member and sole manager shall be BPLP. In supplementation of this, Landis shall not have any interest, ownership, right or obligation of any kind in the D/M Company, including without limitation (i) any right or obligation to participate in the revenues and profits, if any, of the D/M Company, (ii) any obligation to make contributions to the D/M Company in respect of any shortfalls or other capital requirements, and (iii) any right to participate (or be consulted) in connection with the internal management and operations of the D/M Company, including without limitation, the making of any decisions, the establishment and/or modification of any budgets and/or the taking of any actions relating to the D/M Company. The Development Agreement shall be deemed modified and amended in all respects necessary or appropriate to cause the terms of this Paragraph to be implemented.

Pro Forma Budgets and Related Matters . Notwithstanding anything to the contrary contained in the Development Agreement, Landis shall not have any right to approve, participate in, or otherwise be consulted in connection with (i) the establishment or preparation of any Pro Forma Budget and/or any amendments or other modifications to

any such Pro Forma Budget, and/or (ii) any other budget, document, agreement or other matter prepared, related to, or otherwise entered into with respect to any Development Property and/or Project Property or proposed Project Property, and/or (iii) any act or omission by BPLP under the Development Agreement or this First Amendment in connection with any Development Property and/or Project Property or proposed Project Property, it being further agreed that BPLP shall have the right, in its sole and absolute discretion, to establish and/or modify or amend, from time to time and at any time, any such Pro Forma Budget and all such other budgets, documents or other agreements and to take such actions in connection therewith as BPLP, in its sole and exclusive discretion, may deem appropriate. Without limiting the generality of the foregoing, Landis shall not have any right to participate in, review and/or approve any development proposed or undertaken by BPLP (directly or indirectly, including through an Ownership Entity), or any matter relating thereto. The foregoing shall not, however, be deemed to (x) restrict Owner’s right and ability to initiate a Development Proposal pursuant to the Development Agreement (provided however, that, Owner shall have no obligation to consult with BPLP in connection with the preparation of a Pro Forma Budget in connection therewith), (y) restrict or modify Owner’s right and obligation to pay and/or perform the Maintenance Activities pursuant to Sections 2.5(b)(ii) and (iii) of the Development Agreement or (z) limit or modify Owner’s rights and obligations with respect to the Development Property as and to the extent such rights and obligations are specifically reserved to the Owner under the Development Agreement in respect of the Development Property (and, in any event, prior to the same, or any portions thereof, becoming a Project Property). The Development Agreement shall be deemed modified and amended in all respects necessary or appropriate to cause the terms of this Paragraph to be implemented.

Ownership Entities. Notwithstanding anything to the contrary contained in the Development Agreement, the Ownership Entity in respect of any Project Property shall mean a Delaware limited liability company whose sole member and sole manager shall be BPLP. In supplementation of this, Landis shall have no rights or ownership interest of any kind or nature in any Ownership Entity, including without limitation, (i) any right to participate in the revenues and profits, if any, of any Ownership Entity and (ii) any approval rights or any right to participate (or be consulted) in connection with the establishment, management and operations of any Ownership Entity, including without limitation, the making of any decisions, the establishment and/or modification of any budgets and/or the taking of any actions relating to the Ownership Entity. In addition, BPLP shall have no obligation to pay and/or deliver, and Landis shall have no right to receive, any Acquisition Price or Assurance pursuant to the Development Agreement (it being acknowledged that the Project Commencement Payment and the Additional Payment (each as defined and contemplated pursuant to Paragraph 4 of this First Amendment) shall be made in lieu of the Acquisition Price). The Development Agreement shall be deemed modified and amended in all respects necessary or appropriate to cause the terms of this Paragraph to be implemented.

Acquisition Price; Project Commencement Payment and Additional Payment. Notwithstanding anything to the contrary contained in the Development Agreement, effective as of the date of this First Amendment, the terms “Acquisition Price” and “Assurance” shall be deleted in all respects from the Development Agreement.

From and after the date of this First Amendment, in lieu of the Acquisition Price, but in addition to the applicable Land Release Price (of twenty dollars ($20.00) per rentable square foot expected to be developed at the proposed development) that is to be paid in connection with each Project Property (and in connection with Article 7 of the Development Agreement if BPLP exercises its option and acquires the remaining Development Properties, if any, thereunder), BPLP shall pay (the “Project Commencement Payment”) an amount equal to ten and 50/100 dollars ($10.50) per rentable square foot expected to be developed at the applicable Project Property, payable as follows:

(x) with respect to any Project Property that is conveyed to an Ownership Entity (or BPLP) other than pursuant to Sections 7.2 and/or 7.3 of the Development Agreement, to ABL on the date that is six (6) months after the date on which the Land Release Price in connection with such Project Property is paid, and

(y) with respect to any Project Property (including for such purpose the remaining Development Properties) that is conveyed to an Ownership Entity (or BPLP) pursuant to Sections 7.2 and/or 7.3 of the Development Agreement: (1) an amount equal to five dollars ($5.00) per rentable square foot expected to be developed at the applicable Project Property (or the remaining Development Properties, as applicable) shall be paid to Owner simultaneously with the payment of the applicable Land Release Price and (2) an additional amount equal to the Subsequent Project Commencement Payment (as hereinafter defined) shall be paid to ABL on the earlier to occur of (i) the Commencement Date (as hereinafter defined) with respect to each individual building to be constructed on or at the applicable specific Project Property or (ii) the Date of Sale with respect to each specific Project Property.

For purposes hereof: The term “Commencement Date” shall mean, with respect to each individual building to be constructed on or at the applicable Project Property, the date on which a building permit (entitling the development and construction of the entire core and shell of such individual building to be constructed on or at the applicable Project Property without the requirement for any additional or other building or construction related permit) is issued by the West Windsor Township Building Department. The term “Date of Sale” shall mean, with respect to each applicable Project Property, the date on which such Project Property is conveyed by the applicable Ownership Entity (or BPLP) to a third-party unaffiliated with BPLP. The term “Subsequent Project Commencement Payment” shall mean an amount equal to five and 50/100 dollars ($5.50) per rentable square foot expected to be developed in the applicable individual building (or buildings) to be constructed on or at the applicable Project Property, such amount to increase based upon the aggregate change in the

United States Consumer Price Index, if any, from the date such Project Property is acquired by the applicable Ownership Entity (or BPLP) through the Commencement Date or Date of Sale, as applicable, in respect of each applicable individual building (or buildings) to be constructed on or at such Project Property.

Notwithstanding anything to the contrary contained in the Development Agreement or this First Amendment, in the event that the rentable square footage actually developed in any applicable individual building constructed on or at a Project Property by the applicable Ownership Entity (or BPLP or any affiliated entity, but not any unaffiliated entity after the Date of Sale in respect of such Project Property) differs from the expected rentable square footage in respect of which both the Land Release Price and the Project Commencement Payment (including the Subsequent Project Commencement Payment) has been paid, BPLP shall notify ABL (the “Notification”) of such deviation promptly upon its determination of the same. In the event that the actual rentable square footage developed exceeds the expected rentable square footage, the Notification shall include a payment to ABL of an amount equal to thirty and 50/100 dollars ($30.50) times the excess square footage. In the event that the actual rentable square footage developed is less than the expected rentable square footage, ABL shall promptly (and in any event within thirty (30) days after receipt of a Notification) remit to BPLP an amount equal to thirty and 50/100 dollars ($30.50) times the reduced square footage. In both of the foregoing scenarios, if the Subsequent Project Commencement Payment requires adjustment, such adjustment shall include an adjustment in accordance with the United States Consumer Price Index as previously noted in this Paragraph.

In addition to the foregoing, effective as of June 30, 1998, Alan B. Landis shall receive from BPLP an annual amount (the “Additional Payment”) equal to $125,000 payable in full on January 1 of each calendar year (the next payment therefore coming due on January 1, 2005), until the earlier of (a) January 1, 2018, (b) the date on which the Development Agreement is terminated, or (c) the date on which all Development Properties have been conveyed pursuant to the Development Agreement. BPLP shall have no right of offset against such payments. Alan B. Landis acknowledges such payment for the period June 30, 1998 through June 30, 2004 in the amount of $750,000, which amount has been paid and received (or will be paid and received) by Alan B. Landis as provided in Paragraph 2 of that certain Agreement dated as of October 21, 2004 by and among Landis, BPLP and certain other parties thereto. The Development Agreement shall be deemed modified and amended in all respects necessary or appropriate to cause the terms of this Paragraph to be implemented.

Alan B. Landis: No Consulting Fee or Role. Notwithstanding anything to the contrary contained in the Development Agreement, including without limitation, the terms of Section 2.6(a)(iii) thereof, effective as of June 30, 1998, Alan B. Landis shall (i) have no right or obligation to “play a meaningful role in development activities” or any other role in connection with any development activities (regardless of whether such right or obligation is claimed under the Development Agreement, the D/M Company, any Ownership Entity or otherwise) and (ii) shall not receive, or be entitled

to receive, an annual payment of $250,000 from the D/M Company or otherwise in connection with the development operation of the Properties. The Development Agreement shall be deemed modified and amended in all respects necessary or appropriate to cause the terms of this Paragraph to be implemented.

No Sales. Notwithstanding anything to the contrary contained in the Development Agreement, including without limitation, the terms of Article VI thereof, effective as of the date of this First Amendment, no Sale of all or any of the Development Properties may be effected, directly or indirectly, by the Owner, except only to Covance pursuant to the express terms of the Covance Documents.

From time to time, after the date of this Agreement, BPLP and the Owner shall cooperate diligently, reasonably and in good faith to prepare a pro-forma development, construction and operational budget with respect to each Development Property (and all Development Properties taken as a whole), such budgets to be substantially in the form of Exhibit 2.1(c) (each, a “Pro Forma Budget”) (and, from time to time update such budget(s) as reasonably deemed appropriate by BPLP and the Owner). Each such Pro Forma Budget shall include BPLP’s and the Owner’s reasonable good faith estimate of all Development Costs, and any other costs and expenses of any kind or nature, expected to be incurred by or on behalf of the applicable Ownership Entity in connection with the development and construction of the applicable Development Property, as well as all revenues of any kind or nature expected to be received by or on behalf of the applicable Ownership Entity in connection with the applicable Development Property. BPLP and the Owner shall attempt, in good faith, to provide amounts of each line item contained in the Pro Forma Budget which reflect market based expectations for anticipated costs, expenses and revenues from and in connection with such development and construction. (The form of Pro Forma Budget may be modified so that its format is substantially identical to a standard pro forma budget to be developed by Boston Properties, provided that such standard form is substantially similar to the form attached hereto or is approved by the Owner, such approval not to be unreasonably withheld, delayed or conditioned. No formal amendment to this Agreement shall be required to add such revised Pro Forma Budget; the parties shall execute a letter acknowledging and agreeing upon the revised form, which shall be attached hereto as Exhibit 2.1(c)(A) and shall replace Exhibit 2.1(c).)

(d) Design Criteria. The development of each Project Property and each Withdrawn Property shall comply with the Approvals and the Design Criteria set forth for such Property on Exhibit 2.1(d); provided that from and after the date of this Agreement, BPLP may reasonably and in good faith modify such Design Criteria with respect to any Project Property or Withdrawn Property which it has acquired (and the Owner with respect to other Withdrawn Properties), if applicable, to reflect market conditions, applicable Laws and in its business judgment or other circumstances, as reasonably deemed appropriate by BPLP (or the Owner, as

- 11 -

Development Agreement

the case may be) (except no such change in the Design Criteria will be permitted without the prior consent of the Owner (not to be unreasonably withheld, delayed or conditioned) (or BPLP Consent, as the case may be) which would cause the affected Project Property or Withdrawn Property to not be a so-called “Class A” office building which is of at least substantially similar quality and aesthetics to any competitive office property (including without limitation the Developed Properties (as defined in the Contribution Agreement)). Notwithstanding anything contained herein to the contrary, FAR (floor area ratio) for the Development Properties on the west side shall be approximately 13,000 sq. ft. per acre and on the east side shall be approximately 10,000 sq. ft. per acre, unless otherwise agreed by BPLP and the Owner.

(e) Development Proposals. A valid “Development Proposal”

(i)

made by the Owner pursuant to a Proposal Notice must have (A) identified tenants (who have executed letters of intent with material terms summarized (such terms to include at a minimum: term, rent, tenant improvements, lease commissions, additional rent, concessions, options and square footage of space)) for no less than seventy five percent (75%) of the rentable space (subject only to final lease execution to be accomplished prior to Commencement of Development), and (B) the Proposal Information and

(ii)

made by either the Owner or BPLP must be set forth (in reasonably sufficient detail in order for a party to effectively evaluate participation in such Development Proposal) in the BPLP Proposal Notice or the Proposal Notice, as the case may be, as required by Section 2.2(a) and Section 2.2(b).

The “Proposal Information” shall mean, at a minimum, a Pro Forma Budget and a narrative conceptual plan for the development (including a building skin description, a description of the systems to be contained in the building, number of parking spaces (identified by grade, subsurface, or deck parking), location, height, infrastructure and any other mitigations related to such development), and any unusual characteristics related to the site then known, together with an estimated timetable for development. A Development Proposal that also includes preliminary plans and specifications for construction and development and elevations shall constitute an “Enhanced Development Proposal.” The Owner and BPLP each covenant to provide all additional information available to it regarding a proposal requested by the other party. In the event that Covance exercises its rights under the Covance Documents to require the Owner to develop and construct a Property, and there is a conflict between the Development Proposal requirements herein and the development proposal requirements in the Covance Documents (e.g., the pre-leasing requirement), the applicable provisions of the Covance Documents shall govern with respect to such conflicted matters only and the validity of any Development Proposal shall be adjusted to take into account such requirements under the Covance Documents.

2.2 Development.

(a) Initiation of Joint Development by the Owner. Subject to Section 2.2(e), at any time and from time to time during the term of this Agreement, the Owner may give notice to BPLP of a proposed Development Proposal for an individual development site within the Development Properties, such notice to be substantially in the form of Exhibit 2.2A (any such notice, a “Proposal Notice”). If the Proposal Notice contained an Enhanced Development Proposal, BPLP may elect to participate in the proposed development by delivering written notice thereof to the Owner within thirty (30) days after delivery of the Proposal Notice, such form to be substantially in the form set forth in Exhibit 2.2B (the “BPLP Election Notice”), subject to extension under Section 8.3. If the Proposal Notice did not contain an Enhanced Development Proposal, then such thirty (30) day period shall be extended to sixty (60) days after delivery of such Proposal Notice, provided that BPLP delivers a non-binding notice to the Owner within thirty (30) days after delivery of the Proposal Notice stating that BPLP has preliminary interest in the Development Proposal (a “Preliminary Interest Notice”). The parties shall work together, diligently and in good faith, to develop an Enhanced Development Proposal for the development during the period commencing on the date on which the Proposal Notice is delivered. If a Preliminary Interest Notice is timely delivered, BPLP shall have no obligation to participate in such development unless and until a BPLP Election Notice is delivered in a timely fashion (and BPLP shall have no liability in the event BPLP does not deliver a BPLP Election Notice and therefore does not participate in such development). In the event that BPLP determines that the Proposal Notice was not a valid Proposal Notice hereunder, it must notify the Owner thereof within twenty (20) days after delivery of the Proposal Notice, such notice to include in reasonable detail its basis for objections to the content of such Proposal Notice. The parties shall cooperate in good faith to promptly resolve any such dispute and such twenty (20) day period (and accordingly the thirty (30) and sixty (60) day periods described herein) shall be extended until such dispute is resolved.

(b) Initiation of Joint Development by BPLP. Subject to Section 2.2(e), at any time and from time to time during the term of this Agreement, BPLP may give notice to the Owner of a proposed Development Proposal for a Development Property (or any portion thereof), such notice to be substantially in the form set forth in Exhibit 2.2A (any such notice, a “BPLP Proposal Notice”). In the event that the Owner determines that the BPLP Proposal Notice was not a valid BPLP Proposal Notice hereunder, it must notify BPLP thereof with twenty (20) days after delivery of the BPLP Notice, such notice to include in reasonable detail its basis for objections to the content of such BPLP Proposal Notice. The parties shall cooperate in good faith to promptly resolve any such dispute and such twenty (20) day period shall be extended until such dispute is resolved. Landis shall participate in the proposed development provided that the BPLP Proposal Notice is valid.

Development Agreement

(i)

Upon the earlier of (x) the date which is thirty (30) days after the delivery of the Proposal Notice (or sixty (60) days if the Proposal Notice did not contain an Enhanced Development Proposal and a Preliminary Interest Notice was delivered (as such dates may have been extended in accordance with this Agreement or by agreement of the parties)) (so long as no BPLP Election Notice was delivered in such thirty (30) day or sixty (60) day period (as such dates may have been extended in accordance with this Agreement or by agreement of the parties)) or (y) the date on which BPLP declines by written notice to the Owner to participate in development set forth in a Proposal Notice, until the date which is fifteen (15) months after the date such Proposal Notice was delivered, the Owner may commence and thereafter develop such Development Property with one or more third parties as provided below (and such Development Property shall thereupon constitute a “Withdrawn Property”).

(ii)

Upon Commencement of Development, the Owner shall notify BPLP thereof. The Owner and Landis (and their affiliates) shall have the right to develop, construct, finance and own the Withdrawn Properties, and may compete with BPLP and its Affiliates or any Ownership Entity with respect to any such Withdrawn Property, subject however to Section 2.5(a) and Article VI. Development of a Withdrawn Property shall not adversely impact the remaining Development Properties (except as may have been set forth in the Proposal Notice concerning such Withdrawn Property). The development of a Withdrawn Property may be on any business and development terms with any third party, provided that the Design Criteria are complied with and the rental rate on the identified tenants in the Development Proposal and the construction costs are substantially the same as indicated in the relevant Proposal Notice (taking into account any subsequent force majeure event or change in law).

(iii)

Upon Commencement of Development of the Withdrawn Property, the Owner shall diligently complete such development, provided that in the event of a force majeure (such as flood, etc. and including governmental delays (except force majeure does not include matters relating to market conditions or financing)) such covenant to diligently complete

- 14 -

Development Agreement

development shall be stayed until cessation of such event or circumstance (except that the Owner shall in a commercially reasonable matter pursue resolution of any such force majeure delay), and provided that in the event construction is stopped after site work has begun, the Owner’s liability hereunder to diligently complete such development shall be limited to (x) completing construction of the exterior of the building and covering any work or excavated areas with lawn or other appropriate landscaping coverage or, (y) at the Owner’s election, tearing down any uncompleted construction, filling in the excavated area and covering any work or excavated areas with lawn or other appropriate landscaping coverage; in each case in a manner that will not materially adversely impact the remaining Properties and any such coverage shall be generally consistent with Carnegie Center taking into account the circumstances. Any restored Property shall revert to being a Development Property upon the completion of such restoration.

(iv)

In the event that Commencement of Development of the relevant Property does not occur (other than as result of actions taken by BPLP or Boston Properties to hinder or delay development) within such fifteen (15) month period, such Withdrawn Property shall become a Development Property again hereunder, subject to Article VI; provided, that in the event that, within sixty (60) days prior to the end of such fifteen (15) month period, the Owner notifies BPLP of the occurrence of a force majeure event which has caused the Commencement of Development to be delayed (such notice to provide reasonable detail as to the nature and cause of the delay), such fifteen (15) month period shall be automatically extended for the period of such force majeure event, provided however that such period shall not exceed an additional ninety (90) days beyond such fifteen (15) month period.

(v)

If no Commencement of Development has occurred with respect to any Withdrawn Property within such fifteen (15) month period as such period may have been extended for force majeure as provided above then such Withdrawn Property shall revert to being a Development Property hereunder and shall be subject to the terms of this Agreement, including initiation of development by the parties.

(d) Expiration of Proposal Notice and BPLP Proposal Notice. In the event that a Closing has failed to occur with respect to a Project Property and such Closing has been terminated under Article VII, the relevant BPLP Proposal Notice or Proposal Notice shall thereupon expire and such property shall no longer constitute a Project Property, unless otherwise agreed by the Owner and BPLP, but shall continue to be a Development Proposal for all purposes hereunder.

- 15 -

Development Agreement

(e) Blockage Period. No BPLP Proposal Notice may be given with respect to a Withdrawn Property, a Project Property or a Development Property that is subject to a Proposal Notice (until expiration of such notice under Section 2.1(d)). No Proposal Notice may be given with respect to a Development Property or Project Property that is subject to a BPLP Proposal Notice unless and until such BPLP Proposal Notice expires under Section 2.1(d).

(f) Validity of Proposal Notice and BPLP Proposal Notice. Any Proposal Notice or BPLP Proposal Notice which is not valid under Section 2.2(a) or Section 2.2(b) shall not constitute a “Proposal Notice” or “BPLP Proposal Notice,” respectively; provided that if the party contesting such validity has not done so in the twenty (20) day period provided in such Sections, such notice shall be deemed to be valid.

2.3 Consequences of Participation or Non-Participation.

(a) Project Properties, Generally. Upon (i) timely delivery of a BPLP Election Notice (including any extension under Section 8.3), (ii) the expiration of twenty (20) days after delivery of a BPLP Proposal Notice (subject to extension under Section 8.3), or (iii) upon joint agreement by BPLP and the Owner at any time, the portion of the Development Property which was the subject of the Proposal Notice, the BPLP Proposal Notice or such agreement, as applicable, shall constitute a “Project Property” hereunder.

(b) BPLP Acquisition; Withdrawn Properties.

(i)

Notwithstanding BPLP’s election not to participate in a development of such portion of the Development Property, BPLP has the option, exercisable by notice for a period of thirty (30) days from and after the time a Proposal Notice is delivered to elect to acquire such portion of the Development Property subject only to Permitted Exceptions in full for a price equal to (x) $20/rentable square foot of the proposed development plus (y) the Acquisition Price (which shall be paid at the Stabilization Date for such property as if such property were a “Project Property”). The closing for such acquisition shall be on terms and conditions reasonably acceptable to the parties and similar to the terms and condition for conveyances of Project Properties hereunder. The purchase price shall not be subject to any escrow, holdback or indemnification obligations (except that the Acquisition Price shall be paid as provided above). Upon closing thereof, such Property shall no longer be subject to the terms of this Agreement.

Development Agreement

(ii)

Each Withdrawn Property (other than a Withdrawn Property acquired by BPLP) shall be subject to the right of first offer provided for in Article VI and continue to be subject to Section 2.5(a); provided that the “Development Cost” for such property shall include the Carry Cost of such property from the date of its acquisition by BPLP to the Stabilization Date.

2.4 Closings.

(a) Time and Place. The closing of the conveyance of each applicable Project Property to the applicable Ownership Entity (each, a “Closing”) shall take place on the date specified in the Proposal Notice or the BPLP Proposal Notice, as the case may be, which date shall be not less than sixty (60) days nor more than ninety (90) days after the delivery of such Notice, or such other date as BPLP and the Owner shall agree to in writing (each such date, a “Closing Date”). The Closing Date with respect to any Property otherwise acquired by BPLP shall be not less than sixty (60) days nor more than ninety (90) days after the required notice of acquisition.

(i)

Promptly after the date of this Agreement, BPLP and Landis shall form the D/M Company and enter into a limited liability company agreement in a form to be negotiated by the parties pursuant to Article VIII and to be attached as Exhibit 8 (the “D/M LLC Agreement”). The D/M Company will enter into an agreement with each Ownership Entity and the Owner, as applicable providing for development services (including pre-development leasing, managing, construction services and the like) for the period prior to the Stabilization Date for each Project Property and Withdrawn Property (other than a Transferred Property), such agreement to be in a form negotiated by the parties pursuant to Article VIII and to be attached as Exhibit 8 (the “D/M Agreement”).

- 18 -

Development Agreement

(B) in the event third parties are engaged by the D/M Company to perform Project Activities, such third party’s expenses will be borne by the D/M Company and in the event that Closing occurs with respect to the Development Property (or Project Property or Withdrawn Property acquired by BPLP) on which such Project Activities occurred, such third party expenses will constitute “Development Costs” with respect to such Property;

(C) in the event employees of Boston Properties, BPLP or the Service Company or their affiliates are engaged by the Owner or the D/M Company to perform Maintenance Activities or Project Activities, such employees will be charged out on an hourly basis (based upon their annual cash salary multiplied by two, and based upon the total number of hours expected to be performed for such salary in the course of a year as reasonably determined by BPLP), provided that with respect to Project Activities such expenses shall be capped at a budget to be determined by the D/M Company (as more fully set forth in the terms of the D/M LLC Agreement).

“Maintenance Activities” shall mean activities undertaken to maintain the status quo of the Development Properties, including without limitation, compliance with the covenants herein, maintenance of regulatory approvals and permits and the Master Plan and Site Plan, infrastructure and mitigation costs which are not site specific but apply to the Development Properties generally, defense of litigation, accounting services with respect to maintaining insurance, land maintenance, and compliance with law, etc.

(i)

On or prior to the Closing Date with respect to a Project Property, Landis shall form a Delaware limited liability company with BPLP as the sole managing member and Landis as the sole non-managing member, to be governed by a limited liability company agreement in form mutually satisfactory to BPLP and Landis to be attached as Exhibit 8 pursuant to Article VIII (a “Joint Venture Agreement”).

Landis is playing a meaningful role in development activities, a salary or draw payable to him of $250,000 (in the aggregate for all Properties) annually to be structured as agreed by the parties, supplies, utilities, rent and all other costs typically associated with the operation of a development company. In the event that development activities are conducted using resources shared with the Service Company, reasonable and appropriate cost allocation for such resources shall be made.

(b)

Financing.

(i)

If a Closing occurs with respect to a Project Property, BPLP shall obtain, or cause the applicable Ownership Entity to obtain, construction and permanent financing for the development and construction of each Project Property (A) in an amount equal to the aggregate cost of the development and construction of such Project Property as set forth on the then applicable Pro Forma Budget with respect to such Project Property and (B) on the best market terms available to the applicable Ownership Entity, as reasonably determined by BPLP, taking into account all of the terms and conditions of such financing, including without limitation, term, interest rate, principal amount, affirmative, negative and financial covenants.

(ii)

Such financing shall have recourse only to the Project Property; provided, that if such non-recourse financing is not available to the applicable Ownership Entity such financing may have recourse to the Ownership Entity (and if necessary BPLP) and BPLP shall have the sole responsibility with respect to any such recourse. Any such financing may be either debt or equity financing, and may be provided by BPLP and/or its affiliates; provided that, in the event BPLP provides any such financing, the terms and conditions of such financing shall be on terms and conditions no less favorable to the Ownership Entity than would be available from institutional financing sources unrelated to BPLP. Any

At the Stabilization Date (or prior to the Stabilization Date upon thirty (30) days prior notice to Landis) if a Closing has occurred with respect to a Project Property, BPLP shall pay the Acquisition Price to Landis. Landis shall convey all of its interests in the relevant Ownership Entity to BPLP at any time after the Closing with respect to such Property in exchange for payment of the Acquisition Price, or at BPLP’s election by such thirty (30) day notice to Landis prior to the Stabilization Date if BPLP provides reasonable assurance to Landis that such Acquisition Price will be paid at the Stabilization Date.

(ii)

All payments hereunder shall be made by wire transfer of immediately available funds pursuant to instructions to be provided by Landis prior to the Stabilization Date with respect to such Project Property, unless Landis will be paid in Units pursuant to the procedures set forth on Schedule 5.5.

(A)

upon the Stabilization Date, the Stabilized NOI for such Project Property (the “Stabilized NOI”) shall be determined by first determining the net present value of the actual rental income for the Project Property (based on the remaining term certain portion of all leases then in place, without regard to any renewal or extension options or lease periods after termination rights under such leases) discounted at an annual rate of nine percent (9%) and second

- 22 -

Development Agreement

re-amortizing such rental income in equal installments across the remaining terms of all leases, using such annual rate of nine percent (9%); in each case with (A) BPLP’s standard management fee for comparable office properties in comparable locations (to the extent not passed through to tenants), and (B) a vacancy and capital reserve of three percent (3%); provided, however, that such vacancy and capital reserve shall be calculated at one percent (1%) where substantially all of the Project Property is leased to a single tenant for remaining lease term of ten (10) years or longer (without regard to any renewal or extension options);

(B)

the Return Amount shall be deducted from the Stabilized NOI; and

(C)

the remaining amount, if any, but not less than zero ($0.00), shall be capitalized at the Return Rate.

“Return Amount” for each Project Property shall mean an amount determined by multiplying the Development Costs for such Project Property by the Return Rate for such Project Property.

“Return Rate” shall mean a rate which shall equal (a) eleven percent (11%) with respect to a Project Property the development of which was initiated by the Owner where the Development Proposal provided for the Project Property to be leased to a tenant (as evidenced by a lease or a letter of intent to enter into a lease) on a lease covering at least 50,000 rentable square feet which at the Closing Date of the Project Property is an existing tenant (or an affiliate of such a tenant) at one or more of the Developed Properties (as defined in the Contribution Agreement) under a lease having a remaining term in excess of three (3) years (and such tenant actually occupies such leased space); and (b) ten and one half (10.5%) percent in all other cases.

2.8 Existing and Future Lease Provisions. BPLP shall, upon the written request by the Owner or Landis, permit the early termination by tenants of Leases at one or more Developed Properties (for such purpose, each as defined in the Contribution Agreement) in connection with the execution and delivery of a lease by such tenant with respect to a Project Property, each on terms and conditions reasonably satisfactory to BPLP and the Owner or Landis, and occupancy by such tenant of not less than 133% of the rentable square footage by such tenant for initial occupancy under the new lease as compared with the rentable square footage for such tenant under the terminated leases, and provided further that the terms and conditions of such new lease, including without limitation, the rental rates and term of which, are in all material respects generally no less favorable to the landlord than under the terminated Lease for such tenant. Any such termination shall take effect no earlier than the rent commencement of the new lease.

2.9 BPLP Consent. “BPLP Consent” shall mean the written consent of BPLP, which consent shall not be unreasonably withheld, delayed or conditioned. To the extent any BPLP Consent is requested, (w) such request shall boldly state that if no response is received within the required period, such request shall be deemed to be approved; (x) such BPLP Consent shall be deemed to have been given if not received within ten (10) days after written request therefor (unless a different consent period is specified in this Agreement), (y) BPLP in giving such BPLP Consent shall take into account the Master Plan, the terms of any BPLP Proposal Notice and/or any accepted Proposal Notice and the overall development of the Development Properties and the Withdrawn Properties and (z) if BPLP withholds any BPLP Consent the parties agree to promptly submit the matter to arbitration in accordance with the arbitration provisions of Section 8.2.

Sales to owner-occupants are subject to the following:

Development Agreement

(ii)

Such Sales will not, in the aggregate, involve Development Properties containing more than 500,000 rentable square feet; provided that so long as Covance has rights (whether then exercisable or not) to acquire Development Properties under the Covance Documents, no Sale may occur other than to Covance under such Covance Documents.

(iii)

No such Sales may be effected for a price of less than the sum of (A) $30/rentable square foot (increasing annually from the date of this Agreement at the United States Consumer Price Index) and (B) pre-development, design, infrastructure and other costs appropriately and reasonably allocable to the parcel which is the subject of such Sale (which costs will be used from the sale proceeds to reimburse the party who was responsible for such costs). The Owner shall provide BPLP with twenty (20) days prior notice before agreeing to any Sale under this Article VI (a “Sale Notice”), such Sale Notice to include reasonable detail as to the proposed terms of the Sale and the identity of the transferee.

(iv)

The consideration received for such Sale shall be (A) in cash, marketable securities or other equity securities with a readily determinable market value and (B) paid at the closing thereof, and not in installment payments (other than any purchase price adjustments to be paid over time).

(v)

The owner-occupant purchaser (together with its successors and permitted assigns hereunder, the “Purchaser”) shall purchase such property subject to a right of first refusal in favor of BPLP, which shall have the following terms and conditions:

(A)

So long as BPLP (or its affiliates) owns not less than two hundred thousand square feet of space at the Developed Properties (as defined in the Contribution Agreement), if the Purchaser receives a bona fide written offer to effect a Sale of the subject property, it shall promptly give notice thereof to BPLP, such notice to provide the terms and conditions of the proposed Sale and such notice will constitute an irrevocable offer for a period of twenty (20) days to sell or transfer the subject property to BPLP on the same terms and conditions (any such notice, a “ROFR Notice”); provided that in the event that the consideration offered includes marketable securities or other securities with a readily determinable market value, BPLP may offer its own securities or securities of Boston Properties having the same market value and of substantially the same general type or cash in lieu thereof having the same value.

- 40 -

Development Agreement

The Purchaser shall not make or accept any offer to effect a Sale of the subject property (and shall not enter into any agreement or option to do so) without first complying with the right of first refusal provided hereby.

(B)

BPLP shall have the right for a period of twenty (20) days after receipt of such notice to agree to purchase the subject property from the Purchasers on the terms and conditions set forth in the ROFR Notice by giving an irrevocable notice thereof to the Purchaser.

The right of first refusal provided hereby shall expire and be of no further force and effect as of the opening of business on the date which is the second anniversary of the issuance of the certificate of occupancy for the building.

(D)

If BPLP fails to accept the purchase of the subject property within such twenty (20) day period, the Purchaser shall have the right to effect a Sale of the subject property to the transferee identified in the ROFR Notice on the terms and conditions set forth in the ROFR Notice and any such transferee shall acquire the subject property free and clear of this right of first refusal; provided, that such right of first refusal has been complied with.

(vi)

The Purchaser shall also purchase the property subject to a right of first offer in favor of BPLP, which shall commence immediately upon expiration of the right of first refusal and which shall have the following terms and conditions:

(A)

So long as BPLP (or its affiliates) owns not less than two hundred thousand square feet of space at the Developed Properties (as defined in the Contribution Agreement), the Purchaser may not effect a Sale of the subject property unless the Purchaser first gives notice of its intentions to so transfer to BPLP and an offer to so transfer the subject property to BPLP on the terms (including price) set forth in such notice; provided that in the event that the consideration offered includes marketable securities or other securities with a readily determinable market value, BPLP may offer its own securities or securities of Boston Properties having the same market value and of substantially the same general type or cash in lieu thereof having the same value.

- 41 -

Development Agreement

(B)

BPLP shall have the right for a period of thirty (30) days after receipt of such notice to accept such offer to purchase the subject property from the Purchaser. Acceptance of the offer may be made in such period by giving an irrevocable written notice thereof to the Purchaser.

(C)

If the offer by the Purchaser is not accepted by BPLP within such twenty (20) day period, the Purchaser may, for a period of one hundred eighty (180) days after the date it delivered notice under clause (A) above, effect a Sale of the subject property to an unaffiliated third party on terms which are substantially similar (or which are more favorable to the Purchaser) than the terms offered to BPLP, provided that the price may be as low as ninety five percent (95%) of the price offered to BPLP.

(D)

Upon acceptance of any such offer by a third party the Purchaser shall provide notice thereof to BPLP, with reasonable detail as to the basic terms and the identity of the third party. Any such third party shall acquire the subject property free and clear of this right of first offer provided that such right of first offer has been complied with.

(vii)

The right of first refusal and the right of first offer described herein shall not apply to (l) any Sale of the subject property to an Affiliate of the Purchaser, although such Affiliate shall take such subject property subject to this right of first refusal and right of first offer as a “Purchaser” hereunder, (2) any Sale of the Purchaser in a sale of substantially all of the assets of the Purchaser or its affiliates (or a material division of the Purchaser or its affiliates) or a consolidation, merger other similar transaction involving the Purchaser (or its affiliates or a material division thereof) in which the subject property is transferred (except the right of first refusal and the right of first offer shall continue to apply to a subsequent sale, transfer or disposition), and (3) pledges or granting of security interests or similar dispositions in the subject property in connection with any financing.

(viii)

The owner-occupant shall at the closing of such Sale execute a written agreement acknowledging and agreeing to provide the right of first refusal and the right of first offer provided for above and the Owner or owner-occupant shall record a memorandum setting forth the terms of such right of first refusal and right of first offer in the appropriate real estate recording office, such recording to be released upon expiration or satisfaction of such rights.

At the closing of the Sale, the Owner shall cause the owner-occupant to pay to BPLP a dollar amount equal to fifty percent (50%) of the excess of the per rentable square foot sales price offered by the owner-occupant (less the reasonable transaction expenses of the Owner) in the proposed Sale over $20/rentable square foot which is paid at the Closing (to the extent any proceeds are paid over as a result of any purchase price adjustment, BPLP shall be paid its pro rata portion thereof at such time as such payments are made).

6.2 BPLP Purchase.

(i)

Within twenty (20) days after receiving a Sale Notice, BPLP may elect to purchase the Development Property which is subject to the Sale Notice by delivery of notice thereof to the Owner (a “Purchase Notice”), such Purchase Notice to include an offer to purchase such property on substantially similar terms as in the proposed Sale, except that the consideration will consist of

(A)

(1) $20/rentable square foot, plus (2) fifty percent (50%) of the excess of the per rentable square foot sales price offered by the owner-occupant in the proposed Sale over $20/rentable square foot and

(B)

(x) the Acquisition Price (which shall be paid at the Stabilization Date for such property as if such property were a “Project Property”), less (y) the amount set forth in clause (A)(2) above.

- 43 -

Development Agreement

(ii)

BPLP shall have the right for a period of thirty (30) days after receipt of such notice to accept such offer to purchase the subject property from the Owner.

ARTICLE VII - TERMINATION

7.1 Termination with Respect to a Project Property.

(a) Termination. With respect to any Closing of a Project Property, any obligation of BPLP on the one hand or the Owner and Landis, on the other hand, to effect such Closing shall be terminated with prior notice to the other party or parties as follows:

(i) upon thirty (30) days’ notice by the terminating party to the other party if any of the conditions precedent to the obligations of the terminating party set forth in Article III have become incapable of fulfillment (i.e. not susceptible to cure within a 30-day period together with any Grace Period) and have not been waived by a terminating party; and

(ii) subject to the Grace Period, if the terminating party is not then in material breach of a material provision of this Agreement and on the Closing Date (x) any of the conditions precedent to the obligations of the terminating party set forth in Article III shall not have been materially satisfied, and (y) satisfaction of such condition shall not have been waived.

(b) Remedy. The sole and exclusive remedies for breach of a party’s obligation to effect a Closing with respect to a Project Property shall be (i) specific performance in the case of a willful breach and (ii) to cause the Owner and Landis to perform their obligations under Section 7.1(c) in all events. Upon a termination with respect to a single Project Property hereunder all other terms of this Agreement shall continue in full force and effect, subject to Section 7.2. Any such termination by BPLP or by the Owner shall result in the relevant Project Property becoming a Development Property again and remaining subject to the terms of this Agreement. Notwithstanding anything to the contrary contained herein, if either party is unable to close a transaction hereunder on the Closing Date then such party may deliver a notice to such effect to the other party and such party delivering such notice shall have one ninety (90) day period to remedy its inability to close on the Closing Date (such period, the “Grace Period”).

(c) Obligations to Cure. In the event that there is a failure of a condition to BPLP’s obligation to effect a Closing with respect to a Project Property which is susceptible to cure and which has not been waived, within twenty (20) days before the earlier of the expiration of any applicable Grace Period or the thirtieth (30th) day after the Closing Date for such Project Property, BPLP may notify Landis that Landis and/or the Owner must cure the failed condition within ninety (90) days of delivery of such notice, subject to the following terms:

(i) if the failure of such condition has occurred because of the existence of a mortgage, mechanics lien, judgment lien, tax lien or other encumbrance or lien in violation of this Agreement which can be cured by payment of money, Landis or the Owner shall pay such money and cause such encumbrance or lien to be removed; provided, that the Owner or Landis shall not be required to remediate or cure any Environmental Matter;

- 45 -

Development Agreement

(ii) if the failure of such condition requires action by Landis or the Owner in order to cure, Landis and the Owner shall use commercially reasonable efforts to cure such failed condition, but without the obligation to expend material funds unless such failure was caused in willful breach of this Agreement; provided, that the Owner or Landis shall not be required to remediate or cure any Environmental Condition.

7.2 Termination of Entire Agreement. This Agreement shall terminate in its entirety as follows:

(ii) upon the written agreement of the parties hereto; or

(iii) automatically without action by either party upon (x) the commencement of any voluntary bankruptcy, insolvency or similar proceeding against BPLP or Boston Properties by BPLP, Boston Properties or their affiliates or (y) the date which is ninety (90) days after the date on which an involuntary bankruptcy, insolvency or similar proceeding against BPLP or Boston Properties has been instituted by any person (unless such proceeding has been terminated or discharged in such ninety (90) day period).

7.3 Special Acceleration. Upon the death or incapacity of Alan B. Landis, for a period of ninety (90) days after BPLP first has actual knowledge of such death or incapacity, upon notice delivered to the Owner and to Landis, BPLP shall have the right to acquire all of the remaining Development Properties (other than the Development Properties which are then subject to a Proposal Notice or a BPLP Proposal Notice) for a price equal to the aggregate Land
