Electrical

The electrical operating cost of $3.98 per rentable square foot (RSF), which has been included on the enclosed Lessor’s Annual Cost Statement, is based upon the operation of the building, as defined below, at the temperature specifications provided in the SFO. This cost is in line with the discussion we had at our meeting concerning GSA acceptable operating cost estimates.

However, as we have stated previously, the electrical operating loads outlined in the SFO are substantially above what is considered normal and as a result, the building’s electrical operating base has been increased to reflect the abnormal conditions being specified. As outlined below, we have tried to reflect our understanding of the requirements specified in the SFO and restated in your letter dated November 7, 1989.

10 PRICE EVALUATION (PRESENT VALUE) (As Amended 01/30/90)

Evaluation of lease offers will be conducted on the basis of the annual price per square foot, including the ten (10) year option period.

Evaluation of Lease Proposals

(A)

The Offeror must submit his or her offer in sufficient detail for the Government to evaluate the following:

The annual price per net usable square foot for the initial twenty (20) year term including the price for the 150 parking spaces. (This price shall not include any amount for services and utilities i.e., operating expenses).

The base price per net usable square foot for services and utilities (i.e., operating expenses).

The price per net usable square foot for the special requirements specified in Paragraph 103 of the SFO.

The price for the base year for the 350 parking permits per Paragraph 01(D) of the SFO.

The annual price per net usable square foot for the ten (10) year renewal term specified in Paragraph 05 of the SFO.

Items 1, 2, 3, and 4 of this paragraph (A) combined are the total price per square foot offered. If the offer includes annual Consumer Price Index (CPI) adjustments in operating expenses, the net and base prices combined are the total gross annual per square foot price offered. If the offer includes annual adjustments in operating expenses, the base price from which adjustments are made will be the base price for the term of the lease, including any option periods.

Item 5 will be evaluated along with the total price per square foot offered for the initial term to determine which offer is the most economically advantageous to the Government.

Each element of total annual price per square foot, described above, will be evaluated by the Government, and the Government reserves the right to reject any offer if it is determined that the price offered for any element of total annual price per square foot is determined to be unreasonable.

(B)

The Government will conduct a discounted cash flow analysis and reduce prices offered to a composite annual square foot price, as follows:

Parking and wareyard areas will be excluded from the total square footage, but not from the price. For different types of space, the gross annual per square foot price will be determined by dividing the total annual rental by the total square footage and subtracting the amount for parking and wareyard areas.

If annual adjustments in operating expenses will not be made, the gross annual per square foot price will be discounted annually at 8% to yield a gross present value life cycle cost (PVLOC) per square foot.

If annual adjustments in operating expenses will be made, the annual price per square foot, minus the cost of operating expenses and the initial year “1” cost for the three hundred and fifty (350) parking permits, will be discounted annually at 8% to yield a net PVLOC per square foot. The operating expenses will be both escalated at 4% compounded annually and discounted annually at 8% then added to the net PVLOC to yield the gross PVLOC.

The initial year “1” cost for the three hundred and fifty (350) parking permits will also be escalated at 5% compounded annually, and discounted annually at 8%, then added to the net PVLOC to yield the gross PVLOC.

To the gross PVLOC will be added;

The cost of Government-provided services not included in the rental escalated at 4% compounded annually and discounted annually at 8%.

The annualized (over the full term) per square foot cost of any items which are to be reimbursed in a lump-sum payment (the cost of these items is present value; therefore, it will not be discounted.)

(C)

The sum of the above will be the per square foot present value of the offer for price evaluation purposes.

18 OTHER FACTORS (As Amended 12/18/89)

Evaluation Factors for Award

After the review of “Best and Final” offers is completed, the Government will make an award to the responsible offeror(s) whose offer conforms to the Solicitation and is most advantageous to the Government, cost or price and quality factors considered. The quality factors are specified in section “B” of this paragraph. For this solicitation, technical quality is more important than cost or price. As proposals become more equal in their technical merit, the evaluated cost or price becomes more important.

The technical evaluation factors listed below are in order of descending importance insofar as factor “I” is of most importance; Factor “II” is of lessor importance; factors “III-V” are equal to each other but as individual factors not as important as factor “II”; and factor “VI” is of lessor value than any other factor. The final technical rating and the final price will not be combined/evaluated on a percentage basis. The technical factors are as follows:

Qualification of Offeror

Offerors will be evaluated based on the following:

Performance in servicing and maintaining commercial buildings, based on input from previous and current clients (in the absence of previous experience an Operations and Maintenance Plan will be reviewed).

Technical expertise relating to the qualifications of subcontractors, personnel directing the project, prior performance, experience in meeting project budgets and preestablished schedules.

22. TAX ADJUSTMENT GSAR 552.270-24 (JUNE 1985)

(Not Applicable in the Event of Lease Purchase) (As Amended 01/24/90)

(A)

The Government shall pay additional rent during both the initial term and any option periods, if exercised; for its share of increases in real estate taxes over taxes paid for the calendar year in which its lease commences (base year). PAYMENT WILL BE IN A LUMP SUM AND BECOME DUE ON THE FIRST WORKDAY OF THE MONTH FOLLOWING THE MONTH IN WHICH PAID TAX RECEIPTS FOR THE BASE YEAR AND THE CURRENT YEAR ARE PRESENTED, OR THE ANNIVERSARY DATE OF THE LEASE, WHICHEVER IS LATER.

THE GOVERNMENT WILL BE RESPONSIBLE FOR PAYMENT ONLY IF THE RECEIPTS ARE SUBMITTED WITHIN 60 CALENDAR DAYS OF THE DATE THE TAX PAYMENT IS DUE. IF NO FULL TAX ASSESSMENT IS MADE DURING THE CALENDAR YEAR IN WHICH THE GOVERNMENT LEASE COMMENCES, THE BASE YEAR WILL BE THE FIRST YEAR OF A FULL ASSESSMENT.

A “full assessment” shall be deemed to be an assessment based upon the income stream approach to the assessment of buildings. Neither an assessment based upon the cost approach to assessment, nor an assessment based upon the income stream approach which grants allowances for lease up periods, shall be deemed a “full assessment” for the purposes of determining a tax base in accordance with the provisions of this clause. The percentage of Government occupancy for the purpose of this clause is hereby fixed at 98.5%.

Lessors are hereby required to submit documentation from their local jurisdiction’s tax assessor’s office attesting that their tax base has been developed in accordance with the above requirements.

INITIALS: ILLEGIBLE & ILLEGIBLE

INDEPENDENCE SQUARE Lessor Government

January 20, 1990 SFO-89-047 Page 20 of 79

(B)

THE GOVERNMENT’S SHARE OF THE TAX INCREASE WILL BE BASED ON THE RATIO OF rentable SQUARE FEET leased BY THE GOVERNMENT TO THE TOTAL RENTABLE SQUARE FEET IN THE BUILDING. IF THE GOVERNMENT’S LEASE TERMINATES BEFORE THE END OF A CALENDAR YEAR, PAYMENT WILL BE BASED ON THE PERCENTAGE OF THE YEAR IN WHICH THE GOVERNMENT OCCUPIED SPACE. THE PAYMENT WILL NOT INCLUDE PENALTIES FOR NONPAYMENT OR DELAY IN PAYMENT. IF THERE IS ANY VARIANCE BETWEEN THE ASSESSED VALUE OF THE GOVERNMENT’S SPACE AND OTHER SPACE IN THE BUILDING, THE GOVERNMENT MAY ADJUST THE BASIS FOR DETERMINING ITS SHARE OF THE TAX INCREASE.

(C)

THE GOVERNMENT MAY CONTEST THE TAX ASSESSMENT BY INITIATING LEGAL PROCEEDINGS ON BEHALF OF THE GOVERNMENT AND THE LESSOR OR THE GOVERNMENT ALONE. IF THE GOVERNMENT IS PRECLUDED FROM TAKING LEGAL ACTION, THE LESSOR SHALL CONTEST THE ASSESSMENT UPON REASONABLE NOTICE BY THE GOVERNMENT. THE GOVERNMENT SHALL REIMBURSE THE LESSOR FOR ALL COSTS AND SHALL EXECUTE ALL DOCUMENTS REQUIRED FOR THE LEGAL PROCEEDINGS. THE LESSOR SHALL AGREE WITH THE ACCURACY OF THE DOCUMENTS. THE GOVERNMENT SHALL RECEIVE ITS SHARE OF ANY TAX REFUND. IF THE GOVERNMENT ELECTS TO CONTEST THE TAX ASSESSMENT, PAYMENT OF THE ADJUSTED RENT SHALL BECOME DUE ON THE FIST WORKDAY OF THE MONTH FOLLOWING CONCLUSION OF THE APPEAL PROCEEDINGS.

(D)

IN THE EVENT OF ANY DECREASES IN REAL ESTATE TAXES OCCURRING DURING THE TERM OF OCCUPANCY UNDER THE LEASE, THE RENTAL AMOUNT WILL BE REDUCED ACCORDINGLY. THE AMOUNT OF ANY SUCH REDUCTIONS WILL BE DETERMINED IN THE SAME MANNER AS INCREASES IN RENT PROVIDED UNDER THIS CLAUSE.

23 OPERATING COSTS GSAR 552.270-23 (JUNE 1985) (As Amended 01/30/90)

(A)

Beginning with the second year of the lease and each year thereafter including any renewal periods, if exercised; the Government shall pay adjusted rent for changes in costs for cleaning as outlined in Paragraph 85, supplies, materials, maintenance, trash removal, landscaping, water, sewer charges, hearing, electricity, and certain administrative expenses attributable to occupancy. APPLICABLE COSTS LISTED ON GSA FORM 1217, LESSOR’S ANNUAL COST STATEMENT, WHEN NEGOTIATED AND AGREED UPON, WILL BE USED TO DETERMINE THE BASE RATE FOR OPERATING COSTS ADJUSTMENT.

(B)

THE AMOUNT OF ADJUSTMENT WILL BE DETERMINED BY MULTIPLYING THE BASE RATE BY THE PERCENT OF CHANGE IN THE COST OF LIVING INDEX. THE PERCENT CHANGE WILL BE COMPUTED BY COMPARING THE INDEX FIGURE PUBLISHED FOR THE MONTH PRIOR TO THE LEASE COMMENCEMENT DATE WITH THE INDEX FIGURE PUBLISHED FOR THE MONTH WHICH BEGINS EACH SUCCESSIVE 12-MONTH PERIOD.

FOR EXAMPLE, A LEASE WHICH COMMENCES IN JUNE OF 1985 WOULD USE THE INDEX PUBLISHED FOR MAY OF 1985 AND THAT FIGURE WOULD BE COMPARED WITH THE INDEX PUBLISHED FOR MAY OF 1986, MAY OF 1987, AND SO ON, TO DETERMINE THE PERCENT CHANGE. The Cost of Living Index will be measured by the U.S. Department of Labor Revised Consumer Price Index for Wage Earners and Clerical Workers, U.S. City Average all items figure, (1982-84 = 100) published by the Bureau of Labor Statistics. The base rate for the escalation of operating costs is hereby fixed at $3,481,297.44.

INITIALS: ILLEGIBLE & ILLEGIBLE

INDEPENDENCE SQUARE Lessor Government

January 20, 1990 SFO-89-047 Page 21 of 79

PAYMENT WILL BE MADE WITH THE MONTHLY INSTALLMENT OF FIXED RENT. RENTAL ADJUSTMENTS WILL BE EFFECTIVE ON THE ANNIVERSARY DATE OF THE LEASE. PAYMENT OF THE ADJUSTED RENTAL RATE WILL BECOME DUE ON THE FIRST WORKDAY OF THE SECOND MONTH FOLLOWING THE PUBLICATION OF THE COST OF LIVING INDEX FOR THE MONTH PRIOR TO THE LEASE COMMENCEMENT DATE.

(C)

IF THE GOVERNMENT EXERCISES AN OPTION TO EXTEND THE LEASE TERM AT THE SAME RATE AS THAT OF THE ORIGINAL TERM, THE OPTION PRICE WILL BE BASED ON THE ADJUSTMENT DURING THE ORIGINAL TERM. ANNUAL ADJUSTMENTS WILL CONTINUE.

(D)

IN THE EVENT OF ANY DECREASES IN THE COST OF LIVING INDEX OCCURRING DURING THE TERM OF THE OCCUPANCY UNDER THE LEASE, THE RENTAL AMOUNT WILL BE REDUCED ACCORDINGLY. THE AMOUNT OF SUCH REDUCTIONS WILL BE DETERMINED IN THE SAME MANNER AS INCREASES IN RENT PROVIDED UNDER THIS CLAUSE.

(E)

THE OFFER MUST CLEARLY STATE WHETHER THE RENTAL IS FIRM THROUGHOUT THE TERM OF THE LEASE OR IF IT IS SUBJECT TO ANNUAL ADJUSTMENT OF OPERATING COSTS AS INDICATED ABOVE. IF OPERATING COSTS WILL BE SUBJECT TO ADJUSTMENT, IT SHOULD BE SPECIFIED ON BLOCK 19 OF GSA FORM 1364, PROPOSAL TO LEASE SPACE, CONTAINED ELSEWHERE IN THIS SOLICITATION.

24 NET USABLE SPACE (As Amended 09/21/89)

Net usable space is the method of measurement for the area for which the Government will pay a square foot rate. It is determined as follows:

If the space is on a single tenancy floor, compute the inside gross area by measuring between the inside finish of the permanent exterior building walls from the face of the convectors (pipes or other wall hung fixtures), if a convector occupies at least 50 percent of the length of the exterior walls.

If the space is on a multiple tenancy floor, measure from the exterior building walls as above and to the room side finish of the fixed corridor and/or shaft walls and/or the center of the partition separating tenants.

In all measurements, make no deductions for columns and projections enclosing the structural elements of the building and deduct the following from the gross area including their enclosing walls, if relevant.

Toilets and lounges,

Stairwells,

Elevators and escalator shafts,

Building equipment and service areas,

Entrance and elevator lobbies,

Stacks and shafts, and

Aisles, corridors, passageways and hallways in place or required by local codes and ordinances.

In case of failure on the part of the lessor to complete an individual phase within the time fixed in the lease contract or letter of award, the lessor shall pay the Government as fixed and agreed liquidated damages, pursuant to this clause, the sum of $0.05 per square foot per phase for each and every calendar day that the delivery is delayed beyond the date specified for delivery of that specific phase.

27 VENDING FACILITIES

APPROXIMATELY 1200 SQUARE FEET OF THE SPACE IN PARAGRAPH NO. 1 WILL BE USED FOR THE OPERATION OF A VENDING FACILITY(IES) BY THE BLIND UNDER THE PROVISIONS OF THE ▇▇▇▇▇▇▇▇-▇▇▇▇▇▇▇▇ ACT (20 USC 107 ET. SEG.).

GSA WILL CONTROL THE NUMBER, KIND, AND LOCATIONS OF VENDING FACILITIES AND WILL CONTROL AND RECEIVE INCOME FROM ALL AUTOMATIC VENDING MACHINES. THE LESSOR IS REQUIRED TO PROVIDE NECESSARY UTILITIES AND TO MAKE RELATED ALTERATIONS. THE COST OF THE IMPROVEMENTS WILL BE NEGOTIATED AND PAYMENT WILL BE MADE BY THE GOVERNMENT EITHER ON A LUMP-SUM BASIS OR A RENTAL INCREASE.

GSA WILL ASSURE THAT THE FACILITY(IES) DOES NOT COMPETE WITH OTHER FACILITIES HAVING EXCLUSIVE RIGHTS IN THE BUILDING. OFFERORS MUST ADVISE GSA IF SUCH RIGHTS EXIST.

28 ADJUSTMENT FOR VACANT PREMISES GSAR 552.270-25

IF THE GOVERNMENT FAILS TO OCCUPY ANY PORTION OF THE LEASED PREMISES OR VACATES THE PREMISES IN WHOLE OR IN PART PRIOR TO EXPIRATION OF THE FIRM TERM OF THE LEASE, THE RENTAL RATE SHALL BE REDUCED AS FOLLOWS:

THE RATE SHALL BE REDUCED BY THAT PORTION OF THE COSTS PER SQUARE FOOT OF OPERATING EXPENSES NOT REQUIRED TO MAINTAIN THE SPACE. SAID REDUCTION SHALL OCCUR AFTER THE GOVERNMENT GIVES 30 DAYS PRIOR NOTICE TO THE LESSOR, AND SHALL CONTINUE IN EFFECT UNTIL THE GOVERNMENT OCCUPIES THE PREMISES OR THE LEASE EXPIRES OR IS TERMINATED.

37 SPACE EFFICIENCY AND GOOD UTILIZATION (As Amended 07/31/89)

The design of the space offered must be conducive to efficient layout. Due to the potentially significant loss of usable square footage to circulation requirements specified by local codes and ordinances, each offeror is hereby required to submit an 1/8 inch scaled/dimensioned floorplan identifying a schematic circulation pattern for a typical floor, in accordance with the District of Columbia Building Code corridor and egress requirements. Specific attention should be paid to the limit of common path of travel to 100’ and the maximum length of a dead end corridor of 20’.

The floorplan should be prepared based on the following assumptions:

— one hundred percent open plan office occupancy, and

— one hundred percent systems furniture workstations.

INDEPENDENCE SQUARE Lessor Government

January 20, 1990 SFO-89-047 Page 27 of 79

In addition to the aforementioned, a square footage breakdown should be provided for the following:

— interior gross,

— core, and

— net usable

The net usable measurement should specifically quantify, pursuant to Paragraph 24 of the SFO, the deductions made for corridors required by local codes and ordinances.

In light of this requirement for layout efficiency, the offeror’s blue line plans will be scaled by GSA to determine the net usable measurement of the space offered. Subsequently, primary circulation requirements will be identified in accordance with the District of Columbia Building Code corridor and egress requirements.

The net usable measurement of the space offered will then be calculated based on the definition provided in Paragraph 24 of this Solicitation. The floorplans and figures calculated by GSA will be compared with the floorplans and figures prepared by the respective offerors. Any dissimilarities between the two will be reconciled during the negotiation period.

38 FLOOR PLANS AFTER OCCUPANCY (As Amended 04/25/89)

The Government shall not be liable for any costs due to changes or revisions in the requirements of this project which would increase the scope of this contract as originally negotiated and agreed to unless such changes or revisions are authorized and approved by the Contracting Officer in writing. Any request for changes or revisions received by the Contractor shall, therefore, be referred to the Contracting Officer for his approval.

VI. Construction Schedule

Actual construction of the tenant improvements to be made to the leased premises for Phase One shall commence no later than September 1, 1991.

Upon the earlier of either:

Issuance of a written notice, by GSA, authorizing the lessor to proceed with building standard and above standard improvements presuming the base building is completed to a stage where tenant improvements can commence, or

September 1, 1991 and issuance of a written notice, by GSA, authorizing the lessor to proceed with building standard and above standard improvements,

the lessor shall complete each phase within the following time frame:

Phase 1A - one hundred and thirty (130) days

Phase 1B - forty-five (45) days

Successive Phases - sixty (60) days each.

To the extent the Government issues a notice to proceed for more than one phase simultaneously, the time frames for completion outlined above shall be consecutive. For example, if on September 01, 1990 the Government issues a notice to proceed for ▇▇▇▇▇ ▇▇, ▇▇▇▇▇ 2 and Phase 3, the lessor shall complete Phase 1B within forty-five (45) days. Following the forty-five (45) day period for Phase 1B, the lessor shall have sixty days to complete Phase 2 and sixty (60) days following the end of the sixty-day period for Phases 2 to complete Phase 3.

The lessor shall not be obligated to commence tenant buildout unless the Government has approved the working drawings and issued written notice to the lessor to proceed with building standard and above standard work.

The Government reserves the right to access any space within the building for the purpose of installing equipment. GSA shall coordinate, within reason, the activity of Government contractors in order to minimize conflicts with/disruption to other contractors on site.

Access shall not be denied to authorized Government officials including, but not limited to, Government contractors, subcontractors or consultants acting on the behalf of the General Services Administration with respect to this specific project.

If an extended completion schedule is proposed due to the complexity of any given phase or the availability of materials necessary to meet the requirements specified by the Government, the Lessor shall provide to GSA a written request explaining the rationale for the extension and any additional documentation supporting the need for additional time to complete the tenant improvements.

The time frames specified earlier in this subparagraph for the completion of tenant improvements shall not be extended unless the extension of the completion schedule is approved by the GSA, in writing. It will be the Government’s sole determination as to whether said extension shall delay rent commencement, or whether rent will commence as if the extension had not been granted.

VII. Acceptance of Space

The Government shall accept and occupy the space on a phase-by-phase basis. The Government shall pay pro-rata rent for space as soon as the space is accepted as substantially complete by the Government. Following the acceptance by the Government of all phases, a Supplemental Lease Agreement will be issued to establish a composite lease commencement date and fix the twenty (20) year term.

This composite lease commencement date will also become the anniversary date for the purpose of tax and operating cost escalations. The composite lease commencement date shall be the weighted mean of the acceptance dates for the various phases.

The Lessor shall notify the Government in writing at least five (5) days before the space will be complete and ready for inspection. The Government shall then have until the ninth (9th) day following said notification to inspect the space for acceptance.

The entire phase must be substantially complete in order for the Government to accept the space, except for minor “punch list” items. The punch list items, identified by the Government, shall be completed by the lessor within thirty (30) days following acceptance of phase in question. The Government reserves the right to occupy each phase upon acceptance.

The phrase “substantially complete” shall mean the tenant improvements, the common and other areas of the building, and all other things necessary for the Government’s access to the Premises and occupancy, possession, use and enjoyment thereof, as provided in this lease, have been completed or obtained, excepting only such minor matters as do not interfere with or materially diminish such access, occupancy, possession, use or enjoyment.

VIII. Slippage

The Government anticipates that each phase will be completed within the time period established. Failure to complete a phase within the required time frame will constitute slippage.

The Lessor is required to report immediately, in writing, to the Contracting Officer when slippage in the schedule is evident. A revised schedule shall be submitted for approval within five (5) working days of agreement between the Lessor and the Contracting Officer.

To the extent that the lessor is late in meeting any of the time obligations referenced herein, the commencement of rent shall be proportionally postponed by the period of delay.

In the event the Government is late in meeting any of its time obligations as reference herein, the commencement of rent shall occur as if the Government had met its obligations in a timely manner.

Furthermore, in the event the Government fails to award the lease prior to April 30, 1990; rent will commence, pursuant to subparagraph “VI” of this paragraph, as if lease award had occurred on June 1, 1990.

a. Design Intent Drawings

The Government prepares design intent drawings that include basic architectural wall layout and finishes, telephone and electrical outlet locations, furniture layouts and related information.

Any modifications and commensurate costs associated with any modifications to the Governments design intent drawings required due to errors and/ or omissions in the lessor’s construction/working drawings, differing site conditions, failure to meet code requirements or field changes to meet performance requirements shall be the responsibility of the lessor.

b. Base Building Drawings

Within five (5) working days of GSA’s Contracting Officer’s technical representative’s request, the Lessor is required to submit two (2) complete blueline sets of the most current base building drawings (with written notice of percent of design completion) to serve as the basis for the Government’s design intent effort.

Each set of drawings shall include all professional disciplines (architectural, structural, mechanical, electrical, and plumbing). The lessor shall provide the following drawings prior to start of construction of each phase:

INITIALS: ILLEGIBLE & ILLEGIBLE

INDEPENDENCE SQUARE Lessor Government

January 20, 1990 SFO-89-047 Page 39 of 79

Construction/working drawings for each phase, consisting of 12 sets of blue lines and one set of reproducible sepias. Each set will include at a minimum: a legend noting detail sheets, architectural, electrical, mechanical, plumbing, structural, and reflective ceiling plans.

In addition with each submission (phase), the lessor must submit one set of sepias for each discipline showing quantity takeoff deviations from the SFO/above standard alterations under the lease along with summation sheets for quantity takeoffs identifying deviation amounts from the above standard alterations. Structural elevation sheets may be required to show alterations for increased floor loading.

c. Relation of Design Concept Drawings to Construction Drawings

Design development after award will not only be in accordance with the specific solicitation requirements, but also a direct extension of the submitted design concept. The further design development shall retain the functional and basic physical characteristics of that concept.

The Contracting Officer shall reserve the right to reject any aspect of subsequent design development which varies from the concept and which would adversely affect the Government’s use and occupancy of the space in the building as set forth or implied in the body of this solicitation.

The Offeror may propose for the Contracting Officer’s acceptance, or the Contracting Officer may propose for the Offeror’s acceptance, evolutionary adaptations or changes to the concept. Neither party will unreasonably withhold such acceptance of demonstrably beneficial design adaptations of the concept which would not measurably increase the cost of construction, operation or maintenance of the facility.

d. Phases for Interior Design and Construction

The Government reserves the right to access any space within the building for the purpose of installing equipment including but not limited to Telephone and Data/Communications cabling. GSA shall coordinate, within reason, the activity of Government contractors in order to minimize conflicts with/disruption to other contractors on site.

By way of example and not in limitation of the foregoing, Government contractors or subcontractors shall coordinate with the lessor and its general contractor the use of elevators and the availability of electricity, access to such phase or portion and sequencing of the work to be performed by the Government.

The lessor shall not be liable or responsible for and shall have no obligation to provide heating, air conditioning or other building services to the Government in connection to access with its early access to each phase (or portion thereof) unless the Government agrees to compensate the lessor therefor.

The dates specified earlier in this subparagraph for the completion of tenant improvements shall not be extended unless the extension of the completion schedule is approved by the GSA, in writing. It will be the Government’s sole determination as to whether said extension shall delay rent commencement, or whether rent will commence as if the extension had not been granted.

VII. Acceptance of Space

The Government shall accept and occupy the space on a phase-by-phase basis. The Government shall pay pro-rata rent for space as soon as the space is accepted as substantially complete by the Government and subject to the issuance of a certificate of occupancy by the District of Columbia.

Any and all damage caused by the installation of equipment by the Government shall be dealt with in accordance with Clause 16 of GSA Form 3517, General Clauses and shall not impact the payment of rent after acceptance and issuance of a certificate of occupancy for a given phase. Following the acceptance by the Government of all phases, a Supplemental Lease Agreement will be issued to establish a composite lease commencement date and fix the twenty (20) year term.

The phrase “substantially complete” shall mean the tenant improvements, the common and other areas of the Building, and all other things necessary for the Government’s access to the Premises and occupancy, possession, use and enjoyment thereof, as provided in this lease, have been completed or obtained, excepting only such minor matters as do no interfere with or materially diminish such access, occupancy, possession, use or enjoyment.

ATTACHMENT

(A) TO SUPPLEMENTAL LEASE AGREEMENT NO. 12 (REVISED)

The Lessor and the Government agree that, by execution of this Supplemental Agreement No. 12 (revised) to Lease No. GS-11B-00111 (“the Lease”), the Lessor has not waived and expressly reserves its right to pursue its pending claim dated September 9, 1996 against the Government requesting a final decision from the Contracting Officer to establish that the sum of $2,558,413.79 is the real estate tax amount for the NASA Headquarters Building for 1993, which is the “Base Year” of the Lease for purposes of the Tax Adjustment clause, GSAR 552.270-24, of the Lease. The Lessor and the Government recognize (1) that the Lessor has a dispute with the Government concerning the computation of the real estate tax amount for the Base Year of the Lease, which dispute is not settled, resolved or otherwise affected by this Supplemental Agreement No. 12 (revised), and (2) that Lessor’s execution of this Supplemental Agreement No. 12 (revised) does not operate as a concurrence in or acceptance of GSA’s computation of the sum of $2,888,667.66 as the real estate tax base for 1993. The Lessor and the Government further agree that this Supplemental Agreement No. 12 (revised) does not settle or release the Government from any claim(s) by the Lessor to recover lease payments or seek other relief under the Lease as a result of the Government’s assertion that the real estate tax amount for the NASA Headquarters Building is a sum other than $2,558,413.79.

Attention: ▇▇▇▇▇▇ ▇. ▇▇▇▇▇, President

RE: Lease No. GS-11B-00111 dated June 1, 1990, by and between The United States of America (“Government”) and Southwest Market Limited Partnership (“Lessor”) respecting premises comprising 488,734 net usable square feet of office and related space at ▇▇▇ ▇ ▇▇▇▇▇▇, ▇.▇., ▇▇▇▇▇▇▇▇▇▇, ▇.▇. ▇▇▇▇▇ (the “Building”)

Dear ▇▇. ▇▇▇▇▇:

This letter is written in response to the request for novation submitted on behalf of the Lessor, with respect to the Lease referred to above, by ▇▇▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇▇▇, Esq., counsel to Lessor, by letter dated May 29, 1997. In his letter, ▇▇. ▇▇▇▇▇▇▇▇▇▇ pointed out that a novation-in the particular circumstance of this transaction-may not be required by Federal Acquisition Regulation Section 42.1204 nor, by extension, by the Anti-Assignment Act (41 U.S.C. 15).

You have informed us that Boston Properties, Inc., and various affiliated entities including the Lessor, are in the process of forming a publicly-traded real estate investment trust (the “REIT”) which will succeed to the real estate development, redevelopment, acquisition management, operating and leasing businesses owned and controlled by you and ▇▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇▇ either individually or through entities controlled by you. The REIT will be structured as an “umbrella partnership real estate investment trust,” pursuant to which substantially all of such real estate assets will be contributed by you, ▇▇. ▇▇▇▇▇▇▇▇▇ and various affiliated persons and entities, to Boston Properties Limited Partnership, a Delaware limited partnership (“BPLP”), in exchange for interests in the REIT. The sole general partner of BPLP will be Boston Properties, Inc., which will be responsible for managing and operating the real estate assets owned by the REIT. You have also informed us that, due to the fact that a significant ownership interest in the REIT will be retained by you and ▇▇. ▇▇▇▇▇▇▇▇▇, management control of the REIT will also be retained by you.

Specifically with respect to the Building, you have informed us that as part of the REIT formation transactions the constituent partnership interests (both general partnership and limited partnership interests) in the Lessor will be contributed to BPLP (as to a 99% limited partnership interest in Lessor) and to Boston Properties L.L.C. (as to a 1% general partnership interest in Lessor) in exchange for interests in the REIT. The end result of these REIT formation transactions will be that the economic interests in the Lessor will be transformed into interests in the REIT which, in turn, will hold all of the constituent partnership interests to Lessor. Thus, the REIT formation transactions described in this letter (i) will not effect a transfer of the Lease, (ii) will not effect a transfer of the underlying asset (i.e., the Building), and (iii) will not effect a formation or reformation of the partnership that is the Lessor. You have also informed us that the Building will be managed by BPLP, of which Boston Properties, Inc., is the sole general partner, and that payments under the Lease should continue to be made to the same Lessor-Southwest Market Limited Partnership-at the same address as provided in the Lease.

In the circumstances you have described, the public policy concerns that underlie the federal Government rules respecting assignment of contracts are not raised, since the interests of the Lessor in the Building are

Federal Recycling Program [LOGO GOES HERE] Printed on Recycled Paper

identical both before and after the REIT formation, and since the Government will not be subjected to competing or potentially adverse claims with respect to the Lease. Based on these facts, it is our position that a novation agreement with respect to the transactions described above involving the Lease and the Lessor is not required.

Sincerely,

UNITED STATES OF AMERICA
