4.2 Payment of Basic Rent. Basic Rent for each Lease Year shall be payable in equal monthly installments, in advance, without demand, notice, deduction, offset or counterclaim, on or before the first day of each and every calendar month during the Term; provided, however, that the installment of the Basic Rent payable for the first full calendar month of the Term (and, if the Commencement Date occurs on a date other than on the first day of a calendar month, Basic Rent prorated from such date until the first day of the following month) shall be due and payable on the full execution and delivery of this Lease. Tenant shall pay the Basic Rent and all Additional Rent, by good check or in lawful currency of the United States of America, to Landlord at Landlord’s Address, or to such other address or in such other manner as Landlord from time to time specifies by written notice to Tenant.

If Landlord fails to give Tenant notice of its estimated payments due under this Section for any calendar year, the Tenant shall continue making monthly estimated payments in accordance with the estimate for the previous calendar year until a new estimate is provided.

Tenant agrees that Landlord may, by fifteen (15) days prior written notice to Tenant, charge Tenant for the cost of such additional utility or service as Additional Rent, including the cost of any additional transformers, distribution panels, wiring or separate meters, as deemed necessary or desirable by Landlord in its reasonable discretion.

In such event, such dispute shall be resolved by an independent certified public accountant acceptable to Landlord and Tenant, which decision shall be conclusive and binding on both parties and final judgment thereon may be entered in any court of competent jurisdiction.

6.8 Accounting Year. Landlord may adopt a different accounting year than the calendar year, in which case the times for payment of Additional Rent shall be adjusted accordingly.

6.9 Credit for Refunds. In the event that, during or after the Term of this Lease, Landlord shall receive a refund for any tax or other sum included in the calculation of Landlord’s Operating Expenses and paid by Tenant, Landlord shall repay Tenant’s Proportionate Share of such refund (after deducting therefrom the cost and expense of obtaining such refund).

6.10 If Tenant reasonably believes that any Expense Statement includes any charges that are not permitted pursuant to this Article VI or contains an error in calculation or otherwise, then within thirty (30) days of receipt of such Expense Statement, Tenant shall be entitled to the following audit right. Such audit right shall be exercisable by Tenant providing Landlord with a written notice of its exercise of such audit right and a statement enumerating reasonably detailed reason’s for Tenant’s objections to such Expense Statement. If within thirty (30) days after Landlord’s receipt of Tenant’s written notice and statement, Landlord and Tenant are unable to resolve Tenant’s objections, then not later than fifteen (15) days after the expiration of such thirty (30)day period Tenant shall notify Landlord that it wishes to employ an independent “big four” certified public accounting firm or any other independent accounting firm to inspect and audit Landlord’s books and records raised in Tenant’s statement. If Tenant elects to employ such accountant as set forth above, then Tenant shall deliver to Landlord a confidentiality and nondisclosure agreement reasonably satisfactory to Landlord executed by such accountant, and provide Landlord not less than thirty (30)days notice of the date on which the accountant desires to examine Landlord’s books and records during regular business hours; provided, however, that such date shall be thirty (30) days after Tenant delivers such notice. Such audit shall be limited to a determination of whether Landlord calculated the Expense Statement in accordance with the Terms and Conditions of the Lease. All costs and expenses of any such audit shall be paid by the Tenant, except in the event of an error(s) are found totaling more than five percent (5%) of Tenant’s operating expense pass-throughs, then in addition to the refund Landlord shall pay for Tenant’s accountant’s fees.

Tenant

shall not make or permit any other Alterations without the prior written consent of Landlord. Regardless of whether or not Landlord’s consent is required to an Alteration, Landlord may impose any reasonable conditions to the performance of the Alterations, including without limitation, (i) delivery to Landlord of written and unconditional waivers of mechanic’s and materialmen’s liens as to the Premises, the Building and the Land for all work, labor and services to be performed and materials to be furnished, signed by all contractors, subcontractors, materialmen and laborers participating in the Alterations, (ii) prior approval by Landlord of the plans and specifications and Tenant’s contractor(s) with respect to the Alterations, (iii) for structural improvements supervision of the Alterations by Landlord’s representative at Tenant’s expense and (iv) delivery to Landlord of payment and performance bonds naming Landlord and Mortgagee as obligees. All Alterations, whether or not Landlord’s consent is required, shall conform to the requirements of Landlord’s and Tenant’s insurers and of the Federal, state and local governments having jurisdiction over the Premises, including but not limited to all applicable building and fire codes, shall be performed in accordance with the terms and provisions of this Lease in a good and workmanlike manner befitting a first class office building and shall not adversely affect the value, utility or character of the Premises. Should permits of any kind and nature be required by Federal, state or local government(s) having jurisdiction over the Premises, Tenant shall be responsible for securing the permits and the cost of same and furnishing copies of such permits to Landlord.

(B) If the Alterations are not performed as herein required, Landlord shall have the right, at Landlord’s option, to halt any further Alterations, or to require Tenant to perform the Alterations as herein required or to require Tenant to return the Premises to its condition before such Alterations.

(C) Providing Landlord has provided architectural and M.E.P. backgrounds to Tenant within thirty (30) days of the completion of the Alterations, Tenant shall furnish Landlord with one set of reproducible sepias showing the actual, as-built Alterations as they were delivered in the Premises, certified and inspected by the architects and engineers who prepared the plans and specifications.

(D) Notwithstanding the foregoing, if any mechanic’s or materialmen’s lien is filed against the Premises, the Building or the Land for work claimed to have been done for, or materials claimed to have been furnished to or for the benefit of, Tenant, such lien shall be discharged of record by Tenant within ten (10) days by the payment thereof or the filing of any bond required or permitted by law. If Tenant shall fail to discharge any such lien, Landlord may (but shall not be obligated) discharge the same, the cost of which shall be paid by Tenant within three (3) days of demand by Landlord. If Tenant fails to pay the cost within three (3) days of demand by Landlord, Tenant shall pay to Landlord a late charge of five percent (5%) of the amount. In addition, such late payment shall bear interest, at the Interest Rate, from the fourth (4th) day to the date of payment thereof by Tenant. Such discharge by Landlord shall not be deemed to waive or release the default of Tenant in not discharging the same. Neither Landlord’s consent to any Alteration nor anything contained in this Lease shall be deemed to be the agreement or consent of Landlord to subject Landlord’s interest in the Premises, the Building or the Land to any mechanic’s or materialmen’s liens which may be filed in respect of any Alteration.

10.3 Treatment of Alterations at Expiration Date or Earlier Termination of Lease. When Landlord approval is required, Landlord shall notify Tenant prior to granting its approval of the extent of any Alterations which shall remain on the Premises, which Alterations shall be surrendered at the end of the Lease Term as the property of the Landlord. Landlord shall not waive any rights with respect to Alterations made by Tenant and not known to Landlord two months before the end of the Lease Term. Tenant shall not have any obligation to remove any improvements which per Article 10.2 did not require Landlord approval.

Tenant shall have the obligation, with respect to other Alterations, to restore the Premises to the condition existing prior to such Alterations, at Tenant’s expense, to include all necessary design and permit costs, using licensed contractors acceptable to Landlord, unless this obligation was affirmatively waived by Landlord in writing prior to the time such request for approval to construct such Alterations were initially made. Tenant shall have the option, with respect to such Alterations, to pay Landlord the amount of money which would necessary to have the Premises restored to a condition existing prior to such Alterations using an outside licensed third party contractor, to including supervisory, design and permit costs or make the restorations itself. In the former circumstance, if Tenant fails to pay the amount invoiced due within thirty (30) days from receipt of an itemized invoice from Landlord, Tenant shall pay Landlord a late charge of five (5%) percent of the amount invoiced for each month the payment is overdue, plus interest at the Interest Rate from thirty (30) days after invoice submittal until date of payment by Tenant, in addition to the sums described in the original invoice.

Landlord hereby reserves the right, from time to time, to make Alterations to the Building, change the Building dimensions, erect additional stories thereon and attach other buildings and structures thereto, and to erect such scaffolding and other aids to construction as Landlord deems appropriate, and no such Alterations, changes, construction or erection shall constitute an eviction, constructive or otherwise, or permit Tenant any abatement of Rent or claim against Landlord.

Each cable runout from a central distribution point to a wall socket shall be tested to a 155 Mhz transmission rate, and copies of test reports for each run shall be kept and supplied to Landlord upon request. A current wiring map shall be maintained for all low voltage cabling within the Premises and the terminations of each cabling runs shall be identified by number both at the end of the wires and on the socket plate within the wall, to enable rapid re-use of such cabling by a successor tenant. Network hubs and switches shall be considered personal property of the Tenant, but all other cabling infrastructure shall either be surrendered to the Landlord in good operating condition at Lease termination, or at Landlord’s option, removed at Tenant’s expense.

10.6 Surrender of the Premises. Tenant shall peaceably surrender the Premises, including any and all fixtures installed during the Term regardless of whether Landlord or Tenant installed or paid for them, to Landlord on the Expiration Date or earlier termination of this Lease, in broom-clean condition and in as good condition as when Tenant took possession, including, without limitation, the repair of any damage to the Premises caused by the removal of any of Tenant’s personal property from the Premises, except for reasonable wear and tear and loss by fire or other casualty not caused by Tenant or its Agents.

DAMAGE; CONDEMNATION

19.1 Damage to the Premises. If the Premises shall be damaged by fire or other cause without the fault or negligence of Tenant or its Agents, Landlord shall diligently and as soon as practicable after such damage occurs (taking into account the time necessary to effect a satisfactory settlement with any insurance company involved) repair such damage at the expense of Landlord; provided, however, that Landlord’s obligation to repair such damage shall not exceed the proceeds of insurance available to Landlord (reduced by any proceeds retained pursuant to the rights of Mortgagee). Notwithstanding the foregoing, if the Premises or the Building is damaged by fire or other cause to such an extent that, in Landlord’s sole judgment, the damage cannot be substantially repaired within one hundred eighty (180) days after the date of such damage, or if the Premises are damaged during the last two (2) Lease Years, then Landlord or Tenant within thirty (30) days from the date of such damage may terminate this Lease by notice to the other. If either Landlord or Tenant terminates this Lease, the Rent shall be apportioned and paid to the date of such termination. If neither Landlord nor Tenant so elects to terminate this Lease but the damage required to be repaired by Landlord is not repaired within one hundred eighty (180) days from the date of such damage (such one hundred eighty (180) day period to be extended by the period of any delay outside the direct control of Landlord plus a reasonable period for a satisfactory settlement with any insurance company involved), Tenant, within thirty (30) days from the expiration of such one hundred eighty (180) day period (as the same may be extended), may terminate this Lease by notice to Landlord. During the period that Tenant is deprived of the use of the damaged portion of the Premises, and provided such damage is not the consequence of the fault or negligence of Tenant or its Agents, Basic Rent and Tenant’s Proportionate Share shall be reduced by the ratio that the rentable square footage of the Premises damaged bears to the total rentable square footage of the Premises before such damage. All injury or damage to the Premises or the Building resulting from the fault or negligence of Tenant or its Agents shall be repaired by Tenant, at Tenant’s expense, and Basic Rent shall not ▇▇▇▇▇. If Tenant shall fail to do so or if Landlord shall so elect, Landlord shall have the right to make such repairs, and any expense so incurred by Landlord, together with interest thereon at the Interest Rate, shall be paid by Tenant upon demand. Notwithstanding anything herein to the contrary, Landlord shall not be required to rebuild, replace or repair any above-standard work or improvements or any other personal property of Tenant.

19.2 Condemnation. If more than fifty percent (50%) of the Premises or the Building shall be taken or condemned by any governmental or quasi-governmental authority for any public or quasi-public use or purpose (including, without limitation, sale under threat of such a taking), then the Term shall cease and terminate as of the date when title vests in such governmental or quasi-governmental authority, and Basic Rent shall be pro-rated to the date when title vests in such governmental or quasi-governmental authority. If fifty percent (50%) or less of the Premises is taken or condemned by any governmental or quasi-governmental authority for any public or quasi-public use or purpose (including, without limitation, sale under threat of such a taking), Basic Rent and Tenant’s Proportionate Share shall be reduced by the ratio that the portion so taken bears to the rentable square footage of the Premises before such taking, effective as of the date when title vests in such governmental or quasi-governmental authority, and this Lease shall otherwise continue in full force and effect. Tenant shall have no claim against Landlord (or otherwise) as a result of such taking, and Tenant hereby agrees to make no claim against the condemning authority for any portion of the amount that may be awarded as compensation or damages as a result of such taking; provided, however, that Tenant may, to the extent allowed by law, claim an award for moving expenses and for the taking of any of Tenant’s property (other than its leasehold interest in the Premises) which does not, under the terms of this Lease, become the property of Landlord at the termination hereof as long as such claim is separate and distinct from any claim of Landlord and does not diminish Landlord’s award. Tenant hereby assigns to Landlord any right and interest it may have in any award for its leasehold interest in the Premises. Landlord represents and warrants this as of the effective date Landlord is not aware of any pending or possible condemnation proceedings.

No legal process, re-entry, re-letting or taking possession of the Premises by the Landlord shall be construed as an election on its part to terminate this Lease unless a written notice of such intention is given to the Tenant. In the event that Landlord elects to retake or repossess the Premises, the Tenant shall be liable for and shall pay to Landlord, all rental and other indebtedness accrued to date of such repossession, plus at its option, at any time, the Landlord may choose to either: (1) accelerate the entire balance due under the remainder of the Lease and any other monies due under the Lease required to be paid by Tenant to Landlord until the Expiration Date of the Lease, including those referred to in Section 20.2(A) above; or (2) seek payment from Tenant for the difference between all sums due to Landlord from Tenant under this Lease and the amount received by Landlord through re-letting the Premises; Landlord may choose suit under option (2) and later accelerate under option (1); and all reasonable expenses incurred by Landlord in enforcing or defending Landlord’s rights or remedies including reasonable attorney’s fees and twelve percent (12%) interest per annum on all the sum owing by Tenant to Landlord.

If Tenant fails to redeem the personal property so seized, by payment of whatever sum may be due Landlord under and by virtue of the provisions of this lease, then and in that event, Landlord shall have the right, after twenty (20) days written notice to Tenant of its intention to do so, to sell such personal property so seized at public or private sale and upon such terms and conditions as to Landlord may appear advantageous, and after the payment of all proper charges incident to such sale, apply the proceeds thereof to the payment of any balance due to Landlord on account of rent or other obligations of Tenant pursuant to this Lease. In the event there shall then remain in the hands of Landlord any balance realized from the sale of said personal property as aforesaid, the same shall be paid over to Tenant.

(I)

Exercise by Landlord of any one or more remedies hereunder granted or otherwise available shall not be deemed to be a termination of this Lease or an acceptance of surrender of the Premises by Tenant, being understood that such termination or surrender can be effected only by written notice from Landlord specifying such termination. In the event that Landlord elects to terminate this Lease, in addition to Landlord’s other remedies and rights hereunder, Landlord’s obligations toward Tenant shall terminate.

(J)

The Tenant acknowledges that all accounts are due and payable as required in the Lease, and in the event Tenant fails to pay any installment of rent hereunder as and when such installment is due, Tenant shall pay to Landlord a late charge in an amount equal to five percent (5%) of such installment, and the failure to pay such amount shall be an event of default hereunder.

Interest will be charged back to the account due date and apply to all charges due from the Tenant including but not limited to Basic Rent and Additional Rent, taxes, insurance and common area maintenance charges. The provision for such late charges and finance charges shall be in addition to all of Landlord’s other rights and remedies hereunder or at law and shall not be construed as a penalty, liquidated damages or as limiting Landlord’s remedies in any manner.

Tenant further agrees that if Landlord shall have failed to cure such default within the time provided for in this Lease, then Mortgagee shall have an additional thirty (30) days within which to cure such default; provided, however, that if such default cannot be reasonably cured within that time, then such Mortgagee shall have such additional time as may be necessary to cure such default (including, without limitation, the commencement of foreclosure proceedings, if necessary), in which event this Lease shall not be terminated or Basic Rent abated while such remedies are being so diligently pursued. In the event of the sale of the Land or the Building, whether by foreclosure or deed in lieu thereof or otherwise, the Mortgagee or purchaser at such sale shall be responsible for the return of the Security Deposit only to the extent that such Mortgagee or purchaser actually received the Security Deposit.

22.3 Modification Due to Financing. If, in connection with obtaining construction or other financing for the Premises, the Building or the Land, any lender (or Mortgagee) shall request reasonable modifications of this Lease as a condition to such financing, Tenant shall promptly execute a modification of this Lease, provided such modifications do not increase the financial obligations of Tenant hereunder or adversely affect the leasehold interest hereby created or Tenant’s reasonable use and quiet enjoyment of the Premises. Tenant and Guarantor shall each, prior to execution and throughout the Term, upon request from time to time, provide such financial information and documentation about itself to Landlord or Mortgagee as may be requested.

Landlord’s obligation to perform its covenants and agreements hereunder is subject to the condition precedent that this Lease be approved by Mortgagee or the issuer of any commitment to make a construction or mortgage loan. Unless Landlord gives Tenant written notice within thirty (30) days after the date hereof that the Mortgagee or issuer, or both, disapproves this Lease, then this condition shall be deemed to have been satisfied or waived and the provisions of this Section 22.4 shall be of no further force or effect.

22.5 Assignment for Financing Purposes. If, at any time or times, Landlord assigns this Lease or the Basic Rent payable hereunder to the Mortgagee, or to any other party for the purpose of securing financing (the Mortgagee and any other such party are referred to herein as the “Financing Party”), whether such assignment is conditional in nature or otherwise, the following provisions shall apply:

(i) Such assignments to the Financing Party shall not be deemed an assumption by the Financing Party of any obligations of Landlord hereunder unless such Financing Party shall, by written notice to Tenant, specifically otherwise elect;

(ii) To the extent the Financing Party has assumed obligations under (i) above, the Financing Party shall be treated as having assumed such obligations only upon foreclosure of its Mortgage (or voluntary conveyance by deed in lieu thereof) but before the Financing Party conveys the Land, Building or Premises to another party.

Tenant hereby agrees to enter into such agreement or instruments as may, from time to time, be requested in confirmation of the foregoing.

ARTICLE XXIII

SMART Dispute Resolution Procedure

I. Preliminary.

1. Any dispute regarding the terms of a contract, agreement, or business relationship between the parties herein, or involving employees, agents, or other representatives of the parties, shall be resolved, at the election of either party, by the following “SMART” procedure (“Sensible Method for Addressing and Resolving Troubles”).

2. SMART shall be initiated by one party’s sending a certified letter to the other, requesting a resolution of a dispute described in the letter. Such a request shall be made in a timely manner, normally within 3 months after the event which initiated the dispute. Any question regarding timeliness, and its effect on the merits of the claim or costs of and effectiveness of its defense, shall be decided by the arbitrator(s), and may be a factor in the amount or appropriateness of any award, their decision to be final. A document request not to exceed 100 pages in length may accompany such letter.

3. Within 14 days after the receipt of such notice, each party shall designate a representative to meet informally to attempt to resolve the dispute.

In the event that the parties are unable to resolve the matter between them within 30 days after the date of the initial letter, either party may, by a second letter served certified mail on the other party, initiate proceedings for a final and binding resolution of such dispute, controversy or claim by arbitration following the procedures herein set forth, along with a requested award.

II. Arbitration.

4. If the award requested is under $50,000, all evidentiary hearings and decision making shall be accomplished by a single arbiter.

If the parties cannot agree on the arbiter, within 15 days after the date of the second letter they shall each appoint a representative, and the two representatives shall within 10 days jointly nominate the arbiter. Such arbiter shall have at least 10 years active prior experience in the business field in which the dispute arises.

The arbiter shall issue a written report explaining the award.

5. If the award requested is greater than $50,000, or involves relief other than money damages, upon request of either party, the hearings and decision making shall be accomplished by two designated representatives, one appointed by either side, each of which shall have at least 10 years active prior experience in the business field in which the dispute arises. Either party, if it so chooses, may designate a representative employed by, or otherwise affiliated with, the party so designating.

Within 10 days of their appointment the designated representatives shall jointly appoint a neutral arbiter. Such arbiter shall have had significant prior experience in dispute resolution, as a judge, lawyer, arbitrator, or mediator, and prior experience in the business field in which the dispute arises.

If an appointment is required and has not been made within the designated time period, such a choice will be left up to the American Arbitration Association.

The parties shall agree prior to the commencement of hearings whether the neutral arbiter shall participate in the hearings, or shall serve as a final decision maker based on the record only. If they cannot agree, the neutral arbiter shall participate in full.

(i) if the neutral arbiter does not attend the hearings:

At the conclusion of the evidence, each designated representative shall make findings of facts and conclusions of law, together with a suggested award.

If the higher of the two suggested awards is within 20% of the lower, or $30,000, whichever is greater, the amounts shall be compromised and such amount shall be the final reward. Should the suggested awards differ by more, the neutral arbiter shall pick one or the other amounts designated by the designated representatives, but shall not have the power to compromise these amounts. A written report by the neutral arbiter will set forth findings of fact and conclusions of the law in addition to confirming the award. The neutral arbiter shall have power to vary the non-monetary aspect of any award.

(ii) if the neutral arbiter attends the hearings:

The panel shall, by majority vote, issue findings of fact and conclusions of law in connection with its award.

With either procedure, should the amount of the award exceed $250,000, or involve non-monetary remedies, either party may appeal the correctness of the conclusions of law to the Federal Court of E.D. U.S. District Court of the Eastern District of Virginia. Findings of fact shall be subject to judicial review only if they are arbitrary and capricious, an abuse of discretion, or totally unsupported by the evidence, or deficient in other similar standards used for judicial review of administrative decisions in contested cases. Security for the party receiving an award shall be set by the court.

III. General Provisions.

6. Evidence. Rules for discovery, interrogatories, depositions, and other evidentiary issues and a schedule therefore shall be decided by the arbiter(s), in accordance with the procedures of the American Arbitration Association or other rules selected by the arbitrators in their sole discretion. Each party shall submit a discovery plan to the arbiter(s) and have it approved prior to requesting any discovery beyond the initial 100 pages. Oral depositions shall be discouraged unless a deponent cannot easily be made available for actual testimony. The time periods applicable to discovery shall be set to permit compliance with the scheduling provisions of 8) below.

All evidence, whether written or oral, shall be deemed by the parties to be confidential, and it shall not be disclosed to any other person except to the extent reasonably necessary to assist counsel in the proceedings or in preparation for the proceeding.

7. Schedule. The arbitration shall be conducted on an expedited schedule. Unless otherwise agreed by the parties, the initial submissions shall be made, and the hearing shall commence, within 45 days of the initiation of the arbitration. The hearings shall be completed within 30 days thereafter. The award shall be made within 15 days from the close of the hearing. Any failure to render the award within the foregoing time period shall not, however, affect the validity of such awards.

8. Validity. Judgment on the award may be entered in any court having jurisdiction over the necessary party. The award of noncompensatory damages, if made, shall not exceed 50% of compensatory damages and shall be a nonappealable fact. The parties hereby waive their right to proceed judicially in any jurisdiction pending the outcome of the SMART proceedings as outlined above.

9. Costs. Each party shall bear its own costs for representation and preparation. The costs for any neutral arbiter shall be shared equally by the parties. At the conclusion of the arbitration, and in accordance with the general and special rules and policies of the American Arbitration Association, the arbiter may award to the prevailing party costs incurred for preparation and representation, including reasonable attorneys’ fees.

Should a party challenge the existence, validity, terms, or enforceability of these dispute resolution provisions, and if it does not prevail in its challenge, it shall pay the costs and fees as determined by the arbitrator(s).

At any time during the proceedings either party shall have the opportunity to submit an offer for settlement to the opposing party which may be sealed or presented publicly to the arbiter(s), as the initiating party so chooses. Subsequent offers may be made if earlier ones be rejected.

Should the final award be more favorable to the party making such offer of settlement than the pending offer which was not accepted, the party which did not accept such offer shall pay all costs of arbitration, including without limitation the cost to the other party of its expert witnesses, discovery costs, stenographic fees, and attorney’s fees. Such reimbursements, however, shall be limited to the difference between the offer rejected and the actual award. The arbiters shall have the power to award partial costs in the event of a multifaceted award.

10. Supplemental Procedure. The arbitration shall be governed by such of the general and special rules of the American Arbitration Association (AAA) in force as of the date of the proceedings as are not inconsistent with the provisions herein. Should any language contained herein require interpretation beyond the scope of discretion of the arbiter(s), the parties authorize the AAA to perform this role.

11. Review. Prior to the final issuance of any required written report prepared as part of an award, a draft of such report shall be circulated to the parties, giving each the opportunity to comment on the reasoning employed, and the accuracy of the calculation of the award. The arbiter shall set time limits to govern the comment procedure, and may or may not respond to the comments, or revise the award after reading them.

12. Choice of Law. The law applied shall be that of the Commonwealth of Virginia.

Upon each occasion of such space availability, Landlord shall first present to Tenant all office space coming available prior to entering into agreements with any third party tenants or prospective tenants and Landlord shall make such offer to Tenant at the then current market rental rate including market concessions. For the purposes of this paragraph, the term fair market value shall mean only those office buildings of comparable age, size, and location. Tenant’s expansion rights shall be void if Tenant is in Default of the Lease. Tenant will have ten (10) business days to respond to Landlord’s notice of availability. In the event Tenant fails to respond during such ten (10) business day period, the Right of First Refusal shall terminate on the space in question.
