In the event Seller determines at any time that it is unable or unwilling to remove any one or more of such disapproved Additional Title Matters, Seller shall give written notice to Buyer to such effect; in such event, Buyer may, at its option, waive such objection by written notice given to Seller, but only if given on or prior to the sooner to occur of the Closing or within three (3) days after Buyer receives Seller’s notice. If Buyer fails to give such waiver notice by such date, this Agreement shall be deemed to have terminated and the ▇▇▇▇▇▇▇ Money shall be returned to Buyer.

3.3 Title Insurance. Subject to Buyer fulfilling its obligations as stated in paragraph 20 of the Preliminary Commitment and providing an updated survey if required by the Title Company, Seller shall cause Title Company to issue to Buyer at Closing an Extended Coverage Owner’s Policy of title insurance, issued by Title Company in the amount of the Purchase Price dated the date of Closing, insuring Buyer’s title to the Real Property subject to no exceptions other than the standard pre-printed exceptions applicable to an extended coverage policy and the Permitted Exceptions on the 1970 Form B owner’s policy form (the “Title Policy”).

ADDENDUM A

7.5 Prorations.

7.5.1 Items to be Prorated. The following shall be prorated between Seller and Buyer as of the Closing Date (on the basis of the actual number of days elapsed over the applicable period), with Buyer being deemed to be the owner of the Property during the entire day on which the Deed is recorded and being entitled to receive all operating income of the Property, and being obligated to pay all operating expenses of the Property, with respect to such day:

(a) All non-delinquent real estate and personal property taxes and assessments on the Property payable during the current year. Seller shall be responsible for the payment of any real estate and personal property taxes that are delinquent as of the date before Closing, but in no event shall Seller be charged with or be responsible for any increase in the taxes on the Property resulting from the sale of the Property contemplated by this Agreement or from any improvements made or Tenant Leases entered into on or after the Closing Date.

(b) All fixed and additional rents from the Property, security deposits under Tenant Leases (except as hereinafter provided) and other tenant charges. For this purpose, “rents” are intended to include all income from the Property, including license fees and parking and storage revenues. Seller shall deliver or provide a credit in an amount equal to all prepaid rents for periods after the Closing Date and all refundable cash security deposits (to the extent the foregoing were made by tenants under the Tenant Leases and were not applied or forfeited prior to the Date of this Agreement unless such Tenant was required to and did in fact repay the amount so applied or forfeited) to Buyer on the Closing Date. Rents and other tenant charges which are delinquent as of the Closing Date shall not be prorated on the Closing Date. Buyer shall have no duty to collect delinquent rents for Seller after Closing but shall be required to ▇▇▇▇ tenants for delinquent rents in the ordinary course of business for six (6) months after Closing. To the extent Buyer or Seller receives rents (or other tenant charges) on or after the Closing Date, such payments shall be applied first toward the rent (or other tenant charge) owed to Buyer for its period of ownership and then to any delinquent rents (or other tenant charge) owed to Seller, with Seller’s share thereof, if any, being delivered to Seller if and when received by Buyer and Buyer’s share thereof being delivered to Buyer if and when received by Seller. Any post-closing reconciliation payment shall be allocated in accordance with the charges (and in the case of tenant reimbursements, the underlying expenses) in Seller’s and Buyer’s respective periods of ownership. Subject to Buyer’s right to receive a portion of any funds actually collected, Seller hereby reserves the right to pursue any remedy for damages against any tenant owing delinquent rents and any other amounts to Seller (but shall not be entitled to terminate any lease or any tenant’s right to possession). Buyer shall not be required to litigate or declare a default under any Tenant Lease to facilitate Seller’s collection of delinquent rents. With respect to delinquent rents and any other amounts or other rights of any kind respecting tenants who are no longer tenants of the Property as of the Closing Date, Seller shall retain all rights relating thereto.

(d) All other operating expenses of the Property excluding expenses under contracts not assumed by Buyer.

(e) Buyer shall take all steps necessary to effectuate the transfer of all utilities to its name as of the Closing Date, and where necessary, post deposits with the utility companies. Seller shall use commercially reasonable efforts to cause all utility meters to be read as of the Closing Date. Seller shall be entitled to recover any and all deposits held by any

ADDENDUM A

utility company as of the Closing Date. All charges for utilities shall be prorated outside of the escrow contemplated herein within sixty (60) days after the Closing Date.

7.5.2 Calculation. Prorations and payments shall be made on the basis of a written statement furnished to Escrow Holder, Buyer, and Seller by the property manager for the Property at least five (5) business days prior to Closing and approved by Buyer and Seller. In the event any prorations or apportionments made under this Section 7.5 shall prove to be incorrect for any reason, then any party shall be entitled to an adjustment to correct the same. Any item which cannot be finally prorated because of the unavailability of information shall be tentatively prorated on the basis of the best data then available and reprorated when accurate information is available. The obligations of Seller and Buyer under this Section 7.5.2 shall survive the Closing for a period of ninety (90) days and within such period if any pro-rations or apportionments made hereunder shall prove to be incorrect for any reason, then either party shall be entitled to an adjustment to correct the same.

7.6 Closing Costs and Expenses. Buyer and Seller shall each pay their own attorneys fees and expenses to perform their obligations hereunder in addition to the following:

(a) Seller shall pay:

(v) The portion of the real estate excise tax on the Leaseback Amount; and

(vi) Any sales tax on the Personal Property (the value of which shall be as reasonably estimated by Buyer and Seller).

7.7 Delivery Outside of Escrow. Seller shall deliver to Buyer at Closing outside of the Closing escrow the originals of the diligence materials referenced in Article IV (including but not limited to the originals of the Tenant Leases and Contracts and the 6th Floor Lease, if applicable), originals or copies of all materials relating to design and construction of the Project, including all contracts with any contractor, subcontractor, architect, engineer or other designer relating to the development of the Building or construction of tenant improvements by Seller, operating manuals, keys and/or codes to all doors and security equipment, copies of all current

ADDENDUM A

books and records of Seller used in the operation, maintenance and repair of the Property, and such other records and items as reasonably requested by Buyer.

7.8 Refund of Excess Purchase Price.

7.8.1 If Seller enters into the 6th Floor LOI prior to the Closing Date but does not deliver to Buyer a 6th Floor Lease on the terms of the 6th Floor LOI signed by the tenant within thirty (30) days after the Closing Date, the Purchase Price shall be reduced to the amount set forth in Section 2.1.2, the Lease Holdback shall be the calculated under Section 7.2(l)(i), and Escrow Holder shall return to Buyer the amount deposited by Buyer in excess of the actual Purchase Price (except for the amount of the Lease Holdback). If Seller enters into the 6th Floor LOI prior to the Closing Date but the terms of the final 6th Floor Lease do not entitle Seller to receive to the entire amount deposited by Buyer toward the Purchase Price, the Escrow Holder shall be directed to return to Buyer the portion of the Purchase Price not earned by Seller (except for the amount of the Lease Holdback which shall remain in escrow).

7.8.2 In the event the 6^th Floor Lease is not mutually executed and delivered by Seller and the tenant thereunder on or before Closing, then Seller (at Seller’s option) may elect to continue to pursue finalization of the 6^th Floor Lease for a period of thirty (30) days following the Closing Date. Further, in the event Seller elects to pursue the 6^th Floor Lease following Closing as provided herein, then Buyer shall cooperate with Seller in good faith but any approvals required of Buyer shall be given or withheld in Buyer’s sole discretion, and upon Seller’s delivery of a final form of the 6^th Floor Lease to Buyer (in a form approved by Buyer and the tenant thereunder), Buyer shall promptly execute and deliver the 6^th Floor Lease. Notwithstanding anything to the contrary contained in this Agreement or otherwise, under no circumstance shall Seller have an obligation to continue to pursue the 6^th Floor Lease nor shall Seller have any liability to Buyer nor shall Buyer have any liability to Seller for the failure of the parties (or any of them) to agree upon or enter into the 6^th Floor Lease; excepting that to the extent the 6^th Floor Lease is not in final form (i.e., a form that has been agreed upon by Buyer and the tenant thereto and has been executed and delivered by the tenant thereto) within thirty (30) days following the Closing Date, then Seller shall be subject to the provisions of Section 7.8.1.

7.9 Term of Master Lease. If Seller satisfies the requirements of either Section 2.1.1(a) or Section 2.1.1(b) with respect to the 6th Floor Lease, the term of the Master Lease will expire on August 31, 2007.

Notwithstanding anything to the contrary contained herein, no claim for a breach of any representation or warranty of Seller shall be actionable or payable (a) if the breach in question results from or is based on a condition, state of facts or other matter which is actually known by Buyer prior to Closing, (b) unless and only to the extent the valid claims for all such breaches collectively aggregate more than Fifty Thousand Dollars ($50,000), (c) to the extent the maximum aggregate liability of Seller for breach of any or all such representations or warranties exceeds Fifty Thousand Dollars ($50,000), it being agreed that Seller’s maximum aggregate liability for breach of any or all such warranties or representations shall in no event exceed One Million Dollars ($1,000,000) and (d) unless written notice containing a description of the specific nature of such breach shall have been given by Buyer to Seller prior to the expiration of the

ADDENDUM A

Survival Period provided in Section 8.1 and an action shall have been commenced by Buyer against Seller within sixty (60) days after the termination of such Survival Period. This Section shall survive Closing.

8.3.2 No constituent partner in or agent of Seller, nor any advisor, trustee, director, officer, employee, member, partner, participant, representative or agent of any entity that has a direct or indirect interest in Seller, shall have any personal liability, directly or indirectly, under or in connection with this Agreement or any agreement made or entered into under or pursuant to the provisions of this Agreement. Buyer and its successors and assigns and, without limitation, all other persons and entities, shall look solely to Seller’s assets for the payment of any claim or for any performance by Seller. Notwithstanding anything to the contrary contained in this Agreement, neither the negative capital account or capital deficit of any constituent partner in Seller, nor any obligation of any constituent member or partner in Seller of any tier to restore a negative capital account or capital deficit or to contribute capital to Seller, shall at any time be deemed to be the property or an asset of Seller or any such other constituent member or partner. No constituent shareholder in or agent of Buyer, nor any advisor, trustee, director, officer, employee, beneficiary, shareholder, member, partner, participant, representative or agent of any partnership, limited liability company, corporation, trust or other entity that has a direct or indirect interest in Buyer, shall have any personal liability, directly or indirectly, under or in connection with this Agreement or any agreement made or entered into under or pursuant to the provisions of this Agreement, or any amendment or amendments to any of the foregoing made at any time or times, heretofore or hereafter. Seller and its successors and assigns and, without limitation, all other persons and entities, shall look solely to Buyer’s assets for the payment of any claim or for any performance, and Seller, on behalf of itself and its successors and assigns, hereby waives any and all such personal liability. Notwithstanding anything to the contrary contained in this Agreement, neither the negative capital account or capital deficit of any constituent partner or shareholder in Buyer (or in any other constituent member or partner of Buyer), nor any obligation of any constituent member or shareholder or partner in Buyer (or in any other constituent member or partner of Buyer) to restore a negative capital account or capital deficit or to contribute capital to Buyer (or to any other constituent member or partner of Buyer), shall at any time be deemed to be the property or an asset of Buyer or any such other constituent member or partner (and neither Seller nor any of its successors or assigns shall have any right to collect, enforce or proceed against or with respect to any such negative capital account or a member’s or partner’s obligation to restore or contribute).

8.3.3 The foregoing provisions shall be in addition to, and not in limitation of, any further limitation of liability that might otherwise apply (whether by reason of Buyer’s waiver, relinquishment or release of any applicable rights or otherwise).

ARTICLE IX. LOSS BY FIRE OR OTHER CASUALTY: CONDEMNATION

In the event that, after the date hereof but prior to the Closing Date, either any portion of the Property is taken pursuant to eminent domain proceedings or any of the improvements on the Property are damaged or destroyed by any casualty, Seller shall have no obligation to repair or replace any such damage or destruction. Seller shall at Closing assign to Buyer (except to the extent any condemnation proceeds or insurance proceeds are attributable to lost rents or other items applicable to any period prior to the Closing) all claims of Seller respecting any condemnation or casualty insurance coverage, as applicable, and all condemnation proceeds or proceeds from any such casualty insurance received by Seller on account of any casualty. In connection with any assignment of insurance proceeds hereunder, Seller shall credit Buyer with an amount equal to the applicable deductible amount under Seller’s insurance. Notwithstanding the foregoing, if any of the following conditions are met with respect to damage to, or the taking

ADDENDUM A

of, any portion of the Property by reason of a casualty or condemnation occurring between the Date of this Agreement and the Closing, then Buyer may, at its option, terminate this Agreement by notice to the Seller, given on or before the sooner of the Closing date or ten (10) days from the date of occurrence of such casualty or condemnation, whereupon the ▇▇▇▇▇▇▇ Money shall be returned to Buyer (and no party hereto shall have any further obligation in connection herewith except under those provisions that expressly survive a termination of this Agreement): (1) in the event the condemnation award or the reasonable cost of repair for such damage, as applicable, exceeds Two Hundred Fifty Thousand Dollars ($250,000); (2) if the casualty is uninsured, and Seller does not elect to credit Buyer with an amount equal to the reasonable cost to repair such uninsured casualty; (3) if tenants representing 5% or greater of the total rental income from the Property have a right to terminate their Tenant Leases or tenants have the right to ▇▇▇▇▇ their rent; or (4) Lessor has a right to terminate the Ground Lease.

ARTICLE X. POSSESSION

Possession of the Property shall be delivered to Buyer on the Closing Date subject to the rights of tenants under the Tenant Leases.

ARTICLE XI. DEFAULT; REMEDIES

11.1 Default by Buyer. If Buyer fails, without legal excuse, to complete the purchase of the Property in accordance with the terms of this Agreement or otherwise default hereunder, Seller’s sole and exclusive remedy shall be to retain the ▇▇▇▇▇▇▇ Money as liquidated damages. Buyer expressly agrees that the delivery to and the retention of the ▇▇▇▇▇▇▇ Money by Seller represents a reasonable estimation of the damages in the event of Buyer’s default, that actual damages may be difficult to ascertain and that this provision does not constitute a penalty. The foregoing limitation on the liability of Buyer shall not be applicable with respect to Buyer’s obligations to be performed or enforced after Closing.

11.2 Default by Seller. If Seller fails, without legal excuse, to complete the purchase of the Property in accordance with the terms of this Agreement or otherwise defaults hereunder, Buyer may elect to pursue any one or more of the following remedies: (a) terminate this Agreement and receive a refund of the ▇▇▇▇▇▇▇ Money; or (b) ▇▇▇ for damages but in no event shall Buyer be entitled to recovery of any damages, including any award of attorneys’ fees, expenses or costs, in excess of the sums set forth in Section 8.3.1 above; or; or (c) specifically enforce this Agreement. The foregoing limitation on the liability of Seller shall not be applicable with respect to Seller’s obligations to be performed or enforced after Closing or pursuant to the Deed, Assignment and Assumption of Leases, Assignment of Contracts, or ▇▇▇▇ of Sale, subject to Section 8.3.1(c) above.

11.3 Attorneys’ Fees. In the event either party brings an action or any other proceeding against the other party to enforce or interpret any of the terms, covenants or conditions hereof, the party substantially prevailing in any such action or proceeding shall be paid all costs and reasonable attorneys’ fees by the other party in such amounts as shall be set by the court, at trial and on appeal. The right to reimbursement under this Section 11.3 shall not be subject to the limitations under Section 8.3.1 above.

11.4 Transaction Costs. If this Agreement is terminated pursuant to terms of Section 4.5 or Section 7.1, or by Buyer pursuant to Section 6.1.3, Section 8.3.1 or Section 11.2, , then, notwithstanding anything to the contrary contained herein, in addition to a refund of the ▇▇▇▇▇▇▇ Money and any interest earned thereon, Seller shall reimburse Buyer for any out-of-pocket costs incurred by Buyer in connection with this transaction including due diligence costs and legal fees (the “Transaction Costs”), up to a maximum reimbursement of Ninety Thousand Dollars ($90,000).

ADDENDUM A

ARTICLE XII. MISCELLANEOUS

12.1 Brokers and Finders. Each party represents and warrants to the other that no broker or finder has been involved in this transaction except Pacific Real Estate Partners (“Broker”) whose commission shall be paid in full by Seller at Closing pursuant to a separate agreement with Seller; provided, however, this provision shall not create any rights in the Broker or any other third parties. In the event of a claim for broker’s fee, finder’s fee, commission or other similar compensation in connection with this Agreement other than Broker, Buyer, if such claim is based upon any agreement alleged to have been made by Buyer, hereby agrees to indemnify Seller against any and all damages, liabilities, costs and expenses (including, without limitation, reasonable attorneys’ fees and costs) which Seller may sustain or incur by reason of such claim. Seller, if such claim is based upon any agreement alleged to have been made by Seller, hereby agrees to indemnify Buyer against any and all damages, liabilities, costs and expenses (including, without limitation, reasonable attorneys’ fees and costs) which Buyer may sustain or incur by reason of such claim. Notwithstanding anything to the contrary herein, the provisions of this Section 12.1 shall survive the termination of this Agreement or the Closing. Buyer and Seller each acknowledge receipt of the pamphlet “The Law of Real Estate Agency.”

12.2 Notices. All notices, demands, requests, consents and approvals which may, or are required to, be given by any party to any other party hereunder shall be in writing and shall be deemed to have been duly given if (i) delivered personally, (ii) sent by a nationally recognized overnight delivery service, (iii) electronically transmitted with confirmation sent by another method specified in this Section 12.2 or (iv) mailed or deposited in the United States mail and sent by registered or certified mail, return receipt requested, postage prepaid to:

12.3 Amendment, Waiver. No modification, termination or amendment of this Agreement may be made except by written agreement. No failure by Seller or Buyer to insist upon the strict performance of any covenant, agreement, or condition of this Agreement or to exercise any right or remedy shall constitute a wavier of any such breach or any other covenant, agreement, term or condition. No waiver shall affect or alter this Agreement, and each and every covenant, agreement, term and condition of this Agreement shall continue in full force and effect with respect to any other then existing or subsequent breach thereof. All the terms, provisions, and conditions of this Agreement shall inure to the benefit of and be enforceable by Seller’s or Buyer’s permitted successors and assigns.

12.4 Survival. All provisions of this Agreement which involve obligations, duties or rights to be performed after the Closing Date or the recording of the Deed, and all representations and warranties made in or to be made pursuant to this Agreement shall survive the Closing Date and/or the recording of the Deed only to the extent expressly provided herein.

ADDENDUM A

12.5 Captions. The captions of this Agreement are for convenience and reference only and in no way define, limit or describe the scope or intent of this Agreement.

12.6 Merger of Prior Agreements; No Reliance. This Agreement and the exhibits hereto constitute the final and complete agreement between the parties with respect to the purchase and sale of the Property and supersede all prior and contemporaneous agreements, letters of intent and understandings between the parties hereto relating to the subject matter of this Agreement. There are no oral or other agreements, including but not limited to any representations or warranties, which modify or affect this Agreement. Seller shall not be bound by, nor liable for, any warranties, representations or statements of fact or opinion made by any other person, partnership, corporation or other entity, including, without limitation, the Title Company, any surveyor and any consultants. Buyer acknowledges to Seller that in entering into this Agreement, Buyer is not relying on any warranties except those expressly set forth herein.

12.7 No Joint Venture. It is not intended by this Agreement to, and nothing contained in this Agreement shall, create any partnership, joint venture or other arrangement between Buyer and Seller. No term or provision of this Agreement is intended to be, or shall be, for the benefit of any person, firm, organization or corporation not a party hereto, and no such other person, firm, organization or corporation shall have any right or cause of action hereunder.

12.8 Governing Law; Time. This Agreement and the rights of the parties hereto shall be governed by and construed in accordance with the internal laws of the State of Washington. “Day” as used herein means a calendar day and “business day” means any day on which commercial banks are generally open for business. Any period of time which would otherwise end on a non-business day shall be extended to the next following business day. Time is of the essence of this Agreement.

12.9 Exhibits. All exhibits attached hereto or referenced herein are incorporated in this Agreement.

12.10 Severability. In case any one or more of the provisions contained in this Agreement shall for any reason be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provision hereof, and this Agreement shall be construed as if such provisions had not been contained herein.

12.11 Counterparts. This Agreement and the documents to be delivered hereunder may be executed in any number of counterparts, and each such counterpart hereof shall be deemed to be an original instrument, but all such counterparts together shall constitute but one agreement.

12.12 Successors and Assigns. Buyer may not assign or transfer its rights or obligations under this Agreement without the prior written consent of Seller; provided, however, Buyer may assign its interest in this Agreement on or before the Closing Date to a “Qualified Entity” so long as Buyer gives Seller advance written notice thereof and Buyer and the assignee execute and deliver an assignment and assumption agreement (which, among other matters, will confirm the representations and warranties of Buyer under Section 8, with appropriate modifications to reflect the type of entity involved and the jurisdiction in which it was formed) in form reasonably satisfactory to Seller. As used herein, a “Qualified Entity” means an entity owned 50% or more by Buyer which is approved in writing by Seller (which approval shall not be unreasonably withheld). In the event of a permitted transfer to a Qualified Entity, the transferee shall assume in writing all of the transferor’s rights and obligations hereunder, and the transferor shall be released from its obligations hereunder. No consent given by Seller to any transfer or assignment of Buyer’s rights or obligations hereunder shall be construed as a consent to any other transfer or assignment of Buyer’s rights or obligations hereunder. No transfer or

ADDENDUM A

assignment in violation of the provisions hereof shall be valid or enforceable. Subject to the foregoing, this Agreement and the terms and provisions hereof shall inure to the benefit of and be binding upon the successors and assigns of the parties.

12.13 Cooperation with Buyer’s Auditors and SEC Filing Requirements. Seller shall provide to Buyer (at Buyer’s expense) copies of, or shall provide Buyer access to, such factual information as may be reasonably requested by Buyer, and in the possession or control of Seller, or its property manager or accountants, to enable Buyer’s auditor (Deloitte & Touche LLP or any successor auditor selected by Buyer) to conduct an audit of the income statements of the Property for the year to date of the year in which the Closing occurs plus up to the three prior calendar years. Buyer shall be responsible for all out-of-pocket costs associated with this audit. Seller shall cooperate (at no cost to Seller) with Buyer’s auditor in the conduct of such audit. In addition, Seller agrees to provide if requested by such auditor, historical financial statements for the Property, including income and balance sheet data for the Property, whether required before or after Closing. Without limiting the foregoing, (i) Buyer or its designated independent or other auditor may audit Seller’s operating statements of the Property, at Buyer’s expense, and Seller shall provide such documentation as Buyer or its auditor may reasonably request in order to complete such audit, and (ii) Seller shall furnish to Buyer such financial and other information as may be reasonably required by Buyer or any Affiliate of Buyer to make any required filings with the Securities and Exchange Commission or other governmental authority; provided, however, that the foregoing obligations of Seller shall be limited to providing such information or documentation as may be in the possession of, or reasonably obtainable by, Seller, its property manager or accountants, at no material cost to Seller, and in the format that Seller (or its property manager or accountants) have maintained such information.

IN WITNESS WHEREOF, the parties have executed and delivered this Agreement as of the day and year first above written.
