RREEF agrees to indemnify, defend and hold harmless CarrAmerica, its partners, and their respective officers, directors, employees, agents, affiliates, successors and assigns, from and against any and all Losses arising out of, in connection with or incidental to any injury or death to any person or any damage to the Property or any property of third parties or other property of CarrAmerica, or liens which attach to the Property, by reason of RREEF’s or RREEF’s consultants’ or advisors’ activities on the Property prior to Closing; provided, however, that such indemnification shall not apply to hazardous or toxic materials or other condition presently existing on or about the Real Property, whether disclosed to or discovered by RREEF.

In the event, as a result of RREEF’s inspections hereunder, the need arises to notify under applicable law any federal, state or local public agencies of any environmental conditions at the Real Property, RREEF shall immediately notify CarrAmerica. RREEF agrees that CarrAmerica, and not RREEF or RREEF’s representatives, shall make such disclosure as CarrAmerica deems appropriate, unless such disclosure is required by law to be made by RREEF or RREEF’s representatives, in which instance RREEF or such RREEF’s representatives shall make such disclosure and RREEF shall immediately notify CarrAmerica in writing. This obligation shall survive the Closing or any earlier termination of this Agreement.

CarrAmerica agrees to reasonably cooperate with RREEF in connection with RREEF’s review and inspections of the Property during the Contingency Period.

Section 3.03 CarrAmerica’s Delivery of Documents . Promptly following the Effective Date, CarrAmerica shall, at CarrAmerica’s sole cost and expense, either provide RREEF with, or otherwise make available to RREEF for its review, (a) copies of all information and documents relating to the Property in CarrAmerica’s possession and listed on Exhibit F hereto, and (b) all other documents and information in CarrAmerica’s possession, so long as such requested documents and information are neither subject to a legal privilege nor contain CarrAmerica’s trade secrets or proprietary information (such as any appraisal or other economic analysis of the

8

Property). In the event the transaction contemplated herein does not close, RREEF agrees to return to CarrAmerica promptly upon request by CarrAmerica, all documents and information so furnished to RREEF hereunder by or on behalf of CarrAmerica, without retaining copies thereof, and agrees to keep such documents and information obtained from CarrAmerica confidential as provided in Section 9.15 .

(a) CarrAmerica shall, at CarrAmerica’s sole cost and expense, provide to RREEF promptly after the Effective Date, (i) a title report for the entire Real Property (the “ Title Report ”), not more than sixty days old, issued by the Title Company, together with copies of all instruments underlying or giving rise to all exceptions to coverage that would appear in an ALTA owner’s extended coverage title policy, and (ii) a print of the most recent ALTA survey of the Land and Improvements obtained by CarrAmerica (the “ Survey ”). If RREEF determines that any of the exceptions to title reflected in the Title Report are unacceptable for any reason, or that any matter reflected on the Survey (as the same may be updated during the Contingency Period as required by RREEF, at its sole cost and expense) is unacceptable for any reason (in each case, an “ Objectionable Exception ”), RREEF shall so notify CarrAmerica in writing (the “ Title Notice ”) not later than five (5) days prior to the expiration of the Contingency Period. Other than new exceptions discussed below, any title matters not identified as Objectionable Exceptions in the Title Notice shall be deemed “Permitted Exceptions.” Notwithstanding the foregoing, any mortgage lien granted by CarrAmerica, any mechanics lien relating to the construction of the Improvements under a contract entered into by CarrAmerica, or any judgment lien against CarrAmerica recorded against the Real Property shall be deemed an Objectionable Exception and CarrAmerica shall remove or insure over any such lien as an encumbrance against title to the Real Property at or prior to the Closing.

(b) CarrAmerica shall give RREEF written notice (the “ Title Response ”) within two (2) days after receipt of the Title Notice of whether CarrAmerica will undertake to remove or cure the identified Objectionable Exceptions (whether by causing the elimination of such exception, or by obtaining a title insurance endorsement insuring the Venture as to such matters or other remedy reasonably acceptable to RREEF). CarrAmerica, at its option, may direct that all or any portion of the Contribution Amount be used to pay, through the Closing escrow, any monetary liens, encumbrances or other matters constituting Objectionable Exceptions. If CarrAmerica does not elect to remove or cure all of the Objectionable Exceptions, then RREEF may (1) elect in its sole and absolute discretion to terminate this Agreement by written notice to CarrAmerica, in which case the Deposit (including any interest accrued thereon) shall be returned to RREEF and neither party shall have any further rights or obligations hereunder, except as provided in Sections 3.02, 9.03, 9.15 and 9.17 hereof, or (2) proceed to close hereunder, and accept the Property subject to the Objectionable Exceptions (other than liens that CarrAmerica is obligated, or has agreed, to cure or remove) and the same shall thereupon be deemed Permitted Exceptions.

(c) Notwithstanding the above, any new exception revealed by an update to the Title Report first delivered to RREEF after the date of the Title Notice must be designated in writing (the “ New Title Notice ”) by RREEF as an Objectionable Exception, if at all, within five (5) days after receipt of the update to the Title Report. CarrAmerica shall give RREEF a Title

9

Response within five (5) days after receipt of the New Title Notice, and any such new exceptions timely identified as Objectionable Exceptions in the New Title Notice shall be dealt with in the same manner as set forth in Section 3.04(b) above.

Section 3.05 Contracts . Not later than the end of the Contingency Period, RREEF shall notify CarrAmerica of which Contracts the Venture will assume at Closing; provided, however, RREEF agrees that the Venture shall assume any Contract which, by its terms, cannot be terminated prior to the Closing without cost or other penalty. Except as provided above, CarrAmerica shall terminate all Contracts that RREEF does not agree to cause the Venture to assume, effective as of the Closing Date.

Section 3.06 Disclaimer; As Is Transaction . Upon the Closing and delivery by CarrAmerica to the Venture of possession of the Property, RREEF and the Venture shall be deemed to have accepted the Property in its “AS-IS” condition as of the Closing Date, subject only to the representations and warranties expressly provided in Section 5.01 herein and/or the representations and warranties of CarrAmerica contained in any Closing Document executed and delivered at Closing by CarrAmerica pursuant to this Agreement (collectively, “ CarrAmerica’s Warranties ”).
