Formation Transactions and Contribution of Properties

BioMed Realty Trust, Inc. was formed as a Maryland corporation on April 30, 2004. We also formed our operating partnership, BioMed Realty, L.P., as a Maryland limited partnership on April 30, 2004. In connection with our initial public offering in August 2004, we acquired interests in six properties through our operating partnership that were previously owned by limited partnerships and a limited liability company in which Messrs. Gold, Kreitzer, Wilson and McDevitt, entities affiliated with them, and private investors and tenants who are not affiliated with them owned interests.

Contribution Agreements

We received the interests in the properties contributed by our executive officers and their affiliates under contribution agreements with the individuals or entities that held those interests. Under the contribution agreements we agreed that if our operating partnership directly or indirectly sells, exchanges or otherwise disposes of (whether by way of merger, sale of assets or otherwise) in a taxable transaction any interest in the properties contributed by our executive officers and their affiliates before the tenth anniversary of the completion of our initial public offering, then our operating partnership will indemnify each contributor for all direct and indirect adverse tax consequences. The calculation of damages will not be based on the time value of money or the time remaining within the indemnification period. These tax indemnities do not apply to the disposition of a restricted property under certain circumstances.

We have also agreed for a period of ten years following the date of our initial public offering to use reasonable best efforts consistent with our fiduciary duties to maintain at least $8.0 million of debt, some of which must be property specific, to enable the contributors of these properties to guarantee such debt in order to defer any taxable gain they may incur if our operating partnership repays existing debt.

Redemption or Exchange of the Limited Partnership Units in our Operating Partnership

As of October 1, 2005, limited partners of our operating partnership, including Messrs. Gold, Kreitzer, Wilson and McDevitt, have the right to require our operating partnership to redeem all or a part of their units for cash, based upon the fair market value of an equivalent number of shares of our common stock at the time of the redemption, or, at our election, shares of our common stock in exchange for such units, subject to certain ownership limits set forth in our charter. As of March 31, 2006, the limited partners of our operating partnership held units exchangeable for an aggregate of 2,863,564 shares of our common stock, assuming the exchange of units into shares of our common stock on a one-for-one basis.

Other Benefits to Related Parties

Messrs. Gold, Kreitzer and Wilson have agreed to indemnify the lenders of the debt on the contribution properties. These indemnified lenders include Hawthorne Savings, F.S.B. with respect to our Balboa Avenue property, Fremont Investment & Loan with respect to our Bernardo Center Drive and Industrial Road properties, Midland Loan Services, Inc. with respect to our McKellar Court property and PNC Bank, National Association with respect to our Science Center Drive property. The indemnification covers certain losses incurred by the lender as a result of breaches by the borrowers of the loan documents, including losses resulting from environmental hazards found on or in our contributed properties; losses relating to fraud, intentional misrepresentation or misappropriation of certain funds collected from tenants; losses resulting from waste; and losses resulting from the borrowerÕs failure to comply with certain insurance provisions in the loan documents. In connection with our initial public offering, we agreed to indemnify Messrs. Gold, Kreitzer and Wilson against any payments they may be required to make under such indemnification agreements. However, our indemnification obligation will not be effective with respect to losses relating to a breach of the environmental representations and warranties made to our operating partnership by Messrs. Gold, Kreitzer and Wilson in their respective contribution agreements. For losses relating to such breaches, Messrs. Gold, Kreitzer and Wilson have agreed to indemnify our operating partnership.

We have entered into a registration rights agreement with the limited partners in our operating partnership to provide registration rights to holders of common stock to be issued upon redemption of their units. Pursuant to the registration rights agreement, in the fourth quarter of 2005, we filed and caused to become effective a registration statement on Form S-3 for the registration of the common stock to be issued upon redemption of the units.
