No alterations or physical additions in or to the Premises may be made without Landlord's prior written consent, which shall not be unreasonably withheld, conditioned or delayed; however, Landlord may withhold its consent to any alteration or addition that would adversely affect (1) the Buildings' Structure or the Buildings' Systems (including the Buildings' restrooms or mechanical rooms), (2) the exterior appearance of the Buildings, (3) the appearance of the Buildings' common areas or elevator lobby areas, or (4) the provision of services to other occupants of the Buildings. Subject to the provisions of Section 25(dd), Tenant shall not paint or install lighting or decorations, signs, window or door lettering, or advertising media of any type visible from the exterior of the Premises without the prior written consent

All alterations, additions, and improvements shall be constructed, maintained, and used by Tenant, at its risk and expense, in accordance with all Laws; Landlord's consent to or approval of any alterations, additions or improvements (or the plans therefor) shall not constitute a representation or warranty by Landlord, nor Landlord's acceptance, that the same comply with sound architectural and/or engineering practices or with all applicable Laws, and Tenant shall be solely responsible for ensuring all such compliance. Notwithstanding the foregoing, Tenant may make, with at least ten (10) business days' prior written notice to Landlord (but without Landlord's consent), Minor Alterations costing up to Ten Dollars ($10.00) per rentable square foot of the Premises (at Tenant's sole cost and expense).

Tenant shall repair or replace, subject to Landlord's reasonable direction and supervision, any damage to the Buildings outside of the Premises caused solely by the gross negligence or willful misconduct of a Tenant Party. If Tenant fails to commence to make such repairs or replacements within fifteen (15) days after the occurrence of such damage, and to diligently complete such repairs, then Landlord may make the same at Tenant's cost. If any such damage caused solely by the gross negligence or willful misconduct of a Tenant Party occurs outside of the Premises, then Landlord may elect to repair such damage at Tenant's expense, rather than having Tenant repair such damage. The cost of all maintenance, repair or replacement work performed by Landlord under this Section 8(b) shall be paid by Tenant to Landlord within thirty (30) days after Landlord has invoiced Tenant therefor.

(c) Performance of Work. All work described in this Section 8 shall be performed only by Landlord or by contractors and subcontractors reasonably approved in writing by Landlord.

All work affecting the roofs of the Buildings must be performed by Landlord's roofing contractor and no such work will be permitted if it would void or reduce the warranty on the roofs.

(d) Mechanics' Liens. All work performed, materials furnished, or obligations incurred by or at the request of a Tenant Party shall be deemed authorized and ordered by Tenant only, and Tenant shall not permit any mechanics' liens to be filed against the Premises or the Complex in connection therewith. Upon completion of any such work (other than Minor Alterations), Tenant shall deliver to Landlord final lien waivers from all contractors, subcontractors and material men who performed such work. If such a lien is filed, then Tenant shall, within ten days after Landlord has delivered notice of the filing thereof to Tenant (or such earlier time period as may be necessary to prevent the forfeiture of the Premises, the Complex or any interest of Landlord therein or the imposition of a civil or criminal fine with respect thereto), either (1) pay the amount of the lien and cause the lien to be released of record, (2) insure over or bond off such lien to Landlord's reasonable satisfaction, or (3) diligently contest such lien and deliver to Landlord a bond or other security reasonably satisfactory to Landlord. If Tenant fails to timely take any such action, then Landlord may pay the lien claim, and any amounts so paid, including expenses and interest, shall be paid by Tenant to Landlord within ten (10) days after Landlord has invoiced Tenant

therefor. Landlord and Tenant acknowledge and agree that their relationship is and shall be solely that of"landlord tenant" (thereby excluding a relationship of "owner-contractor," "owner-agent" or other similar relationships). Accordingly, all material men, contractors, artisans, mechanics, laborers and any· other persons now or hereafter contracting with Tenant, any contractor or subcontractor of Tenant or any other Tenant Party for the furnishing of any labor; services, materials, supplies or equipment with respect to any portion of the Premises, at any time from the date hereof until the end of the Te=, are hereby charged with notice that they look exclusively to Tenant to obtain payment for same. Nothing herein shall be deemed a consent by Landlord to any liens being placed upon the Premises, the Complex or Landlord's interest therein due to any work performed by or for Tenant or deemed to give any contractor or subcontractor or material man any right or interest in any funds held by Landlord to reimburse Tenant for any portion of the cost of such work. Tenant shall defend, indemnify and hold harmless Landlord and its agents and representatives from and against all claims, demands, causes of action, suits, judgments, damages and expenses (including attorneys' fees) in any way arising from or relating to the failure by any Tenant Party to pay for any work performed, materials furnished, or obligations incurred by or at the request of a Tenant Party. This indemnity provision shall survive termination or expiration of this Lease.

(e) SCIF Space. Landlord agrees that the use and maintenance of one (1) Sensitive Compartmented Information Facilities ("SCIF") of not more than five thousand (5,000) square feet in each of the Building 1 Premises and the Building 2 Premises that contain or may contain from time to time, as Tenant designates, U.S. Government classified information (collectively "SCIF Areas"), shall be deemed a Permitted Use pursuant to the this of this Lease. The installation of any SCIF Areas in the Premises shall be subject to.Landlord's prior written approval, which approval shall not be unreasonably withheld, conditioned or delayed, except in the event that any such installation will or may affect the exterior or structure of the Building(s) or will or may materially adversely affect the mechanical, electrical, plumbing, HVAC or other systems or the exterior or structure of the Building(s), in which event such consent may be withheld by Landlord in its sole discretion, and shall otherwise be performed in accordance with the terms and provisions of the Lease, including the this of Exhibit D, if included as part of the initial Tenant Improvements, or shall be performed in accordance with the this and provisions of this Section 8, to the extent not included as part of the initial Tenant Improvements. Notwithstanding anything in this Lease to the contrary, Tenant may, at its own expense, provide its own locks and electronic or non-electronic controlled-access and alarm systems in connection with the SCIF Areas; provided, however, that Tenant shall furnish Landlord with a key, badges or other methods of access to any SCIF Areas within two (2) days after installation of any such locks or electronic or non-electronic controlled-access and alarm system and that upon the expiration or earlier termination of the Lease, Tenant shall surrender all such keys (and badges, if Tenant leaves the access control system in the Premises) to Landlord. Landlord shall comply with all reasonable security measures pertaining to the SCIF Areas. Landlord shall have no obligation to provide any services, including janitorial service or cleaning, in the SCIF Areas unless such SCIF Areas are unlocked and made available to Landlord's cleaning personnel at the time such personnel are in the Premises. If Landlord must access a SCIF Area, Tenant shall promptly provide Landlord access thereto, subject to such reasonable requirements as are required by third parties; provided, however, nothing in this Paragraph will be deemed or construed to limit Landlord's right of entry without Tenant's consent or prior notice in the case of a real or apparent emergency as provided in Section 23(a).

9. Use. Tenant shall use the Premises only for the Permitted Use and shall comply with all Laws relating to the use, condition, access to, and occupancy of the Premises and will not commit waste, overload the Buildings' Structure or the Buildings' Systems (subject to the provisions of Section 7(b)). Tenant and its employees shall have the non-exclusive right to use the fire stairs, lobbies and common areas of the building as reasonably necessary to conduct Tenant's business operations at the Premises.

photocopier toner] and then only in compliance with all Laws). Tenant shall not use any substantial portion of the Premises for a "call center," any other telemarketing use, or any credit processing use. If, because of a Tenant Party's acts in violation of this Section, or because Tenant vacates the Premises and does not provide reasonable access control thereafter, the rate of insurance on the Buildings or their contents increases, then Tenant shall pay to Landlord the amount of such increase on demand, and acceptance of such payment shall not waive any of Landlord's other rights. Tenant shall conduct its business and use commercially reasonable efforts to control each other Tenant Party so as not to create any nuisance or unreasonably interfere with other tenants or Landlord in its management of the Buildings.

10. Assignment and Subletting.

(a) Transfers. Except as provided in Section lOCh), Tenant shall not, without the prior written consent of Landlord, (1) assign, transfer, or encumber this Lease or any estate or interest herein, whether directly or by operation of law, (2) permit any other entity to become Tenant hereunder by merger, consolidation, or other reorganization; (3) if Tenant is an entity other than a corporation whose stock is publicly traded, permit the transfer of an ownership interest in Tenant so as to result in a change in the current control of Tenant, (4) sublet any portion of the Premises, (5) grant any license, concession, or other right of occupancy of any pOliion of the Premises, or

(6) permit the use of the Premises by any parties other than Tenant (any of the events listed in Section 10(a)(1) through 10(a)(6) being a "Transfer").

Landlord shall not unreasonably withhold, delay or condition its consent to any assignment or subletting of the Premises, provided that the proposed transferee (1) is fmancially capable of assuming the obligations of tenant hereunder, (2) is reputable, (3) will use the Premises for the Permitted Use (thus, excluding, without limitation, uses for credit processing and telemarketing) and will not use the Premises in any xxxxxx that would conflict with any exclusive use agreement or other similar agreement entered into by Landlord with any other tenarit of the Buildmgs or Complex, (4) will not use the Premises,Buildings or Complex in a xxxxxx that would materially increase the pedestrian or vehicular traffic to the Premises, Buildings or Complex; (5) is not a governmental entity, or subdivision or agency thereof, and (6) is not another occupant ofthe Buildings or Complex and Landlord is able to provide reasonably equivalent space within the Buildings or· the Complex; otherwise, Landlord may withhold its consent in its sole discretion. Additionally, Landlord may withhold its consent in its sole discretion to any proposed Transfer if any monetary Event of Default by Tenant then exists. The consent standards and procedures described in this Section 10 shall also apply to any subsequent Transfers.

(c) Request for Consent. If Tenant requests Landlord's consent to a Transfer, then, at least fifteen (15) business days prior to the effective date of the proposed Transfer, Tenant shall provide Landlord with a written description 6f all terms and conditions of the proposed Transfer, copies of the proposed documentation, and the following information about the proposed transferee: name and address; reasonably satisfactory information about its business and business history; its proposed use of the Premises; banking, financial, and other credit information; and general references sufficient to enable Landlord to determine the proposed transferee's creditworthiness and character ("Tenant's Request Notice").

(d) Conditions to Consent. If Landlord consents to a proposed Transfer, then the proposed transferee shall deliver to Landlord a written agreement whereby it expressly assumes Tenant's obligations hereunder; however, any transferee of less than all of the space in the Premises shall be liable only for obligations under this Lease that are properly allocable to the space subject to the Transfer for the period of the Transfer. No Transfer shall release Tenant from its obligations under this Lease, but rather Tenant and its transferee shall be jointly and severally liable therefor. Landlord's consent to any Transfer shall not waive Landlord's rights as to any subsequent Transfers. If an Event of Default occurs while the Premises or any part thereof are subject to a Transfer, then Landlord, in addition to its other remedies, may collect directly from such transferee all rents becoming due to Tenant and apply such rents against Rent. Tenant authorizes its transfer fees to make payments of rent directly to Landlord upon receipt of notice from Landlord to do so following the occurrence of an Event of Default hereunder.

Each subtenant or licensee of Tenant shall be deemed, automatically upon and as a condition of its occupying or using the Premises or any part thereof, to have agreed to be bound by the terms and conditions set forth in this Section lO(e). The provisions of this Section lO(e) shall be self-operative, and no further instrument shall be required to give effect to this provision.

(f) Recapture. Landlord may, within thirty (30) days after receipt of Tenant's Request Notice with respect to (i) sublease for any period of time (only) space on a floor of a Building for which Tenant (or a Permitted Transferee) is not leasing all of the rentable square footage on such floor (but expressly excluding any first floor computer lab space in the Building 2 Premises, for which Landlord's recapture right shall not apply), and/or (ii) any request to assign or sublease all or any other Premises for the remainder of the Term ((i) and/or (ii), as applicable, a "Recapturable Sublease"), at the time of such request, recapture and cancel this Lease as to the portion of the Premises proposed to be sublet or assigned as of the date the proposed Transfer is to be effective. Additionally, notwithstanding anything to the contrary in this Section 10, if at any time during the Lease Term Tenant desires in good faith to sublet any of the Premises when Tenant delivers Tenant's Request Notice, such notice will specify that it is sent for the additional purpose of determining whether Landlord will exercise its recapture rights, and not have to contain the identity of the proposed assignee, subtenant or other party, the proposed documentation, the certification stating whether or not any premium or other consideration is being paid, and a description of its business or the most recent financial statement or other evidence of financial responsibility of such proposed assignee, subtenant or other party notwithstanding the terms of Section 1 O(c) above. Landlord shall have the right in its sole and absolute discretion to recapture and cancel this Lease with respect to the proposed Transfer space that is a Recapturable Sublease by sending Tenant written notice of such termination within thirty (30) days after Landlord's receipt of Tenant's Request Notice. If Landlord does not cancel this Lease with respect to the proposed Transfer space that is a Recapturable Sublease (or if Landlord fails to send a notice to Tenant electing to recapture and cancel this Lease with respect to such space), then, at any time prior to the date that is one hundred eighty (180) days after the date Landlord receives Tenant's Request Notice, Tenant may sublease the proposed Transfer space described in Tenant's Request Notice to a third party sublease without Landlord's right to recapture, but still subject to the terms of this Article 10. After the expiration of such one hundred eighty (180) day period, Landlord's right to recapture in accordance with the terms of this Lease will once again be applicable, subject to Tenant's right to then again deliver Tenant's Request Notice seeking a determination of whether Landlord will exercise its recapture rights. The cost of any construction required to permit the operation of the proposed Transfer space separate from the balance of the Building 1 Premises or Building 2 Premises, as applicable, shall be paid by Tenant to Landlord as Additional Rent under this Lease, unless the separation of such space results solely from Landlord's exercise of its recapture rights (in which case Landlord shall pay such cost of construction required to permit the operation of the proposed Transfer space separate from the balance of the Building 1 Premises or Building 2 Premis~s, as applicable). If Landlord recaptures and cancels this Lease as to any portion of the Premises, then this Lease shall cease for such portion of the Premises and Tenant shall pay to Landlord all Rent accrued through the cancellation date relating to the portion of the Premises covered by the proposed Transfer, and as to that portion of the Premises which is not part of the proposed Transfer space, this Lease shall remain in full force and

effect. Thereafter, Landlord may lease such portion of the Premises to the prospective transferee (or to any other person) without liability to Tenant.

(1) This Lease shall be subordinate to any deed of trust, mortgage, or other security instrument (each, a "Mortgage"), or any ground lease;master lease, or primary lease (each, a "Primary Lease"), that now or hereafter covers all or any part of the Building 1 Premises and/or Building 2 Premises (as applicable) (the mortgagee under any such Mortgage, benefIciary under any such deed of trust, or the lessor under any such Primary Lease is referred to herein as a "Landlord's Mortgagee"), subject to the execution of an SNDA (defIned below) by any then-current Landlord's Mortgagee and Tenant (or any Permitted Transferee, as applicable). Landlord has obtained a subordination, non-disturbance and attornment agreement ("SNDA") from the current

Landlord's Mortgagee, and Tenant and Landlord's Mortgagee (existing as of the date of this Lease) executed and delivered such SNDA concurrently with the execution and delivery of this Lease). Any Landlord's Mortgagee may elect, at any time, unilaterally, to make this Lease superior to its Mortgage, Primary Lease, or other interest in the Premises by so notifying Tenant in writing. If at any time Landlord refinances the Building 1 Premises and/or the Building 2 Premises, as applicable, Tenant shall from time to time, within ten (10) business days after written request therefor execute and return to Landlord (or such .other party designated by Landlord) an SNDA on such future Landlord's Mortgagee's form, in recordable form if required, subject to such reasonable modifications as a Landlord's Mortgagee and Tenant may reasonably request and subsequently agree to evidence the subordination to, and non-disturbance of this Lease (the "Mortgagee Form").

Tenant shall, within five (5) business days after Landlord's request therefor, execute and deliver such Prescribed Form, and if Tenant fails timely to do so, the same shall constitute an immediate Event of Default and this Lease shall automatically be deemed to be subordinate to such Mortgage.

(2) If Landlord's Mortgagee shall succeed to the interest of Landlord under this Lease, the Mortgagee Form shall contain such protections of Landlord's Mortgagee and Tenant as are customary for a Lease of this size, scope and importance. Landlord's Mortgagee shall have no liability or responsibility under or pursuant to the terms of this Lease or otherwise after it ceases to own an interest in the Complex.

(b) Partial Taking -Tenant's Rights. If any part of the Buildings leased by Tenant under this Lease becomes subject to a Taking and such Taking will prevent Tenant from conducting on a permanent basis its business in the Premises in a manner reasonably comparable to that conducted immediately before such Taking, then Tenant may terminate this Lease with respect to such Building only as of the date of such Taking by giving written notice to Landlord within thirty (30) days after the Taking, and Basic Rent and Additional Rent shall be apportioned as of the date of such Taking. If Tenant does not terminate this Lease with respect to such Building only, then Rent shall be abated on a reasonable basis as to that portion of the Premises within the applicable Building rendered untenantable by the Taking.

(c) Partial Taking -Landlord's Rights. If any material portion, but less than all, of the Building 1 Premises or the Building 2 Premises, as applicable, becomes subject to a Taking, or if Landlord is required to pay any of the proceeds arising from a Taking to a Landlord's Mortgagee, then Landlord may terminate

this Lease by delivering written notice thereof t6 Tenant within thirty (30) days after such Taking, and Basic Rent and Additional Rent shall be apportioned as of the date of such Taking.

(e) Award. If any Taking occurs, then Landlord shall receive the entire award or other compensation for the Land, the Buildings, and other improvements taken; however, Tenant may separately pursue a claim (to the extent it will not reduce Landlord's award) against the condemnor for the value of Tenant's personal property which Tenant is entitled to remove under this Lease, moving costs, loss of business, and other claims it may have.

(f) Clarification. For the purposes of clarification, in the event of any Taking which affects Building 1 but not Building 2 (or vice versa), the provisions of this Section 14 shall apply only to the portion of the Building 1 Premises (or Building 2 Premises, as applicable) affected by such Taking and the Lease with respect to the unaffected portion of the Premises shall remain unmodified and in full force and effect.

15. Fire or Other Casualty.

(a) Repair Estimate. If the Building 1 Premises and/or the Building 2 Premises, as applicable, or a Building (in which the Tenant is leasing space) is damaged by fire or other casualty (a "Casualty"), Landlord shall, within ninety (90) days after such Casualty, deliver to Tenant a good faith estimate (the "Damage Notice") of the time needed to repair the damage caused by such Casualty.

(c) Landlord's Rights. If a Casualty damages the Building 1 Premises and/or the Building 2 Premises, as applicable, or a material portion of a Building (in which Tenant is leasing space) and (1) Landlord reasonably estimates that the damage to the Building 1 Premises and/or the Building 2 Premises; as applicable, cannot be repaired within the Repair Period, (2) the damage to the Building 1 Premises and/or the Building 2 Premises, as applicable, exceeds fifty percent (50%) of the replacement cost thereof (excluding foundations and footings), as reasonably estimated by Landlord, and such damage occurs during the last two years of the Term, (3) regardless of the extent of damage to the Building 1 Premises and/or the Building 2 Premises, as applicable, the damage is not fully covered by Landlord's insurance policies (or by the insurance Landlord is required to maintain pursuant to the provisions of this Lease), without regard to any deductible, or (4) Landlord is required to pay any insurance proceeds arising out of the Casualty to a Landlord's Mortgagee, then, for items (1) and (2) only, Landlord may terminate this Lease with respect to the Building 1 Premises and/or the Building 2 Premises, as applicable, by giving written notice of its election to terminate within thirty (30) days after the Damage Notice has been delivered to Tenant, and, for items (3) and (4) only, Landlord or Tenant may terminate this Lease with respect to the Building

1 Premises and/or the Building 2 Premises, as applicable, by giving written notice of its election to terminate within thirty (30) days after the Damage Notice has been delivered to Tenant.

If Tenant has the right to terminate this Lease pursuant to part (3) or (4) of the fIrst sentence of this Section 15(c) but does not exercise such termination right within such thirty (30) day period after delivery of the Damage Notice, then Tenant's right to terminate shall automatically expire and be of no further force or effect. If pursuant to this Section 15(c) Landlord or Tenant shall terminate with respect to either Building 1 or Building 2, Tenant shall have the option to terminate for the other Building, which option shall be exercised within thirty (30) days following receipt of Landlord's notice of termination, and if Tenant fails to exercise such right within such thirty (30) day period, such termination right shall automatically lapse and be of no further force or effect.

If this Lease with respect to the Building 1 Premises and/or the Building 2 Premises, as applicable, is terminated under the provisions of this Section 15, Landlord shall be entitled to the full proceeds of the Landlord's insurance policies providing coverage for all alterations, improvements and betterments in the Building 1 Premises and/or the Building 2 Premises, as applicable (but not the insurance that Tenant acquires for the Building(s)).

(e) Abatement of Rent. If the Building 1 Premises and/or the Building 2 Premises, as applicable, are damaged by Casualty, Rent for the portion of the Building 1 Premises and/or the Building 2 Premises, as applicable, rendered untenantable by the damage shall be abated on a reasonable basis from the date of damage until the completion of Landlord's repairs (or until the date of termination of this Lease by Landlord or Tenant as provided above, as the case may be), unless such damage was caused by the gross negligence or willful misconduct of Tenant or a Tenant Party, in which case, Tenant shall continue to pay Rent without abatement.

The filing of a petition by or against Tenant (the term "Tenant" shall include; for the purpose of this Section 17(g), any guarantor of Tenant's obligations hereunder) (1) in any bankruptcy or other insolvency proceeding; (2) seeking any relief under any state or federal debtor relief law; (3) for the appointment of a liquidator or receiver for all or substantially all of Tenant's property or for Tenant's interest in this Lease; (4}for the reorganization or modification of Tenant's capital structure; or (5) in any assignment for the benefit of creditors proceeding; however, if such a petition is filed against Tenant, then such filing shall not be an Event of Default unless Tenant fails to have the proceedings initiated by such petition dismissed within. ninety (90) days after the filing thereof.

18. Remedies. Upon any Event of Default, Landlord may, in addition to all other rights and remedies afforded Landlord hereunder· or by law or equity, take anyone or more of the following actions:

(a) Termination of Lease. Terminate this Lease by giving Tenant written notice thereof, in which event Tenant shall pay to Landlord the sum of (1) all Rent accrued hereunder through the date of termination,

(2) all amounts due under Section 19(a), and (3) an amount equal to (A) the total Rent that Tenant would have been required to pay for the remainder of the Term discounted to present value at a per annum rate equal to the "Prime Rate" as published on the date this Lease is terminated by The Wall Street Journal, Eastern Edition, in its listing of "Money Rates", minus (B) the then present fair rental value of the Premises for such period, similarly discounted;

(b) Termination of Possession. Terminate Tenant's right to possess the Premises without terminating this Lease by giving written notice thereof to Tenant, in which event Tenant shall pay to Landlord (1) all Rent and other amounts accrued hereunder to the date of termination of possession, (2) all amounts due from time to time under Section 19(a), and (3) all Rent and other net sums required hereunder to be paid by Tenant during the remainder of the Term,. diminished by any net sums thereafter received by Landlord through reletting the Premises during such period, after deducting all costs incurred by Landlord in reletting the Premises. If Landlord elects to

proceed under this Section l8(b), Landlord may remove all of Tenant's property from the Premises and store the same in a public warehouse or elsewhere at the cost of, and for the account of, Tenant, without becoming liable for any loss or damage which may be occasioned thereby. Landlord shall use reasonable efforts to relet the Premises on such terms as Landlord in its sole discretion may determine (including a term different from the Term, rental concessions, and alterations to, and improvement of, the Premises); however, Landlord shall not be obligated to relet the Premises before leasing other portions of the Building or Complex and Landlord shall not be obligated to accept any prospective tenant proposed by Tenant unless such proposed tenant meets all of Landlord's leasing criteria. Landlord shall not be liable for, nor shall Tenant's obligations hereunder be diminished because of, Landlord's failure to relet the Premises or to collect rent due for such reletting. Tenant shall not be entitled to the excess of any consideration obtained by reletting over the Rent due hereunder. Reentry by Landlord in the Premises shall not affect Tenant's obligations hereunder for the unexpired Term; rather, Landlord may, from time to time, bring an action against Tenant to collect amounts due by Tenant, without the necessity of Landlord's waiting until the expiration of the Term. Unless Landlord delivers written notice to Tenant expressly stating that it has elected to terminate this Lease, all actions taken by Landlord to dispossess or exclude Tenant from the Premises shall be deemed to be taken under this Section l8(b). If Landlord elects to proceed under this Section l8(b), it may at any time elect to terminate this Lease under Section l8(a); or

(c) Perform Acts on Behalf of Tenant. Perform any act Tenant is obligated to perform under the terns of this Lease (and enter upon the Premises in connection therewith if necessary) in Tenant's name and on Tenant's behalf, without being liable for any claim for damages therefor, and Tenant shall reimburse Landlord on demand for any expenses which Landlord may incur in thus effecting compliance with Tenant's obligations under this Lease (including, but not limited to, collection costs and legal expenses), plus interest thereon at the Default Rate. In all instances, Landlord shall use commercial reasonable efforts to mitigate its damages.

19. Payment by Tenant; Non-Waiver; Cumulative Remedies.

(a) Payment by Tenant. Upon any Event of Default, Tenant shall pay to Landlord all·reasonable costs incurred by Landlord (including court costs and reasonable attorneys' fees and expenses) in (1) obtaining possession of the Premises, (2) removing and storing Tenant's or any other occupant's property, (3) repairing, restoring, altering, remodeling, or otherwise putting the Premises into condition acceptable to a new tenant, (4) if Tenant is dispossessed of the Premises and this Lease is not terminated, reletting all or any part· of the Premises (including brokerage commissions, cost of tenant finish work, and other costs incidental to such reletting), (5) performing Tenant's obligations which Tenant failed to perform, and (6) .enforcing, or advising Landlord of, its rights, remedies, and recourses arising out of the default. To the full extent permitted by law, Landlord and Tenant agree the federal and state courts of the state in which the Premises are located shall have exclusive jurisdiction over any matter relating to or arising from this Lease and the parties' rights and obligations under this Lease.

(b) No Waiver. Landlord's acceptance of Rent following an Event of Default shall not waive Landlord's rights regarding such Event of Default. No waiver by Landlord of any violation or breach of any of the terms contained herein shall waive Landlord's rights regarding any future violation of such term. Landlord's acceptance of any partial payment of Rent shall not waive Landlord's rights with regard to the remaining portion of the Rent that is due, regardless of any endorsement or other statement on· any instrument delivered in payment of Rent or any writing delivered in connection therewith; accordingly, Landlord's acceptance of a partial payment of Rent shall not constitute an accord and satisfaction of the full amount of the Rent that is due.

(c) Tenant's Right to Redeem the Premises. Tenant hereby waives any and all rights to redeem the Premises which may accrue to Tenant prior to any eviction proceeding. Tenant's waiver shall apply to any right of redemption that may be presently, or in the future, provided by law. .

(d) Cumulative Remedies. Any and all remedies set forth in this Lease: (1) shall be in addition to any and all other remedies Landlord may have at law and/or in equity, (2) shall be cumulative, and (3) may be pursued successively or concurrently as Landlord may elect. The exercise of any remedy by Landlord shall not be deemed an election of remedies or preclude Landlord from exercising any other remedies in the future.

20.Landlord's Lien. Landlord· hereby forever waives all liens, security interests, encumbrances, and rights of distraint that do or may arise under or in connection with this Lease, whether by statute, contract, common law or otherwise.

21.Surrender of Premises. No act by Landlord shall be deemed an acceptance of a surrender of the Premises, and no agreement to accept a surrender of the Premises shall be valid unless it is in writing and signed by Landlord. At the expiration or termination of this Lease, Tenant shall deliver to Landlord the Premises with all improvements located therein in good condition, free of Hazardous Materials placed on .the Premises during the Term in violation of Laws, broom-clean, reasonable wear and tear (and condemnation and Casualty damage, as to which Sections 14 and 15 shall control) excepted, and shall deliver to Landlord all keys to the Premises. Tenant may remove all trade fIXtures, furniture, and personal property placed in the Premises or elsewhere in the Buildings by Tenant (but Tenant may not remove any wiring or cabling unless Landlord requires such removal). Additionally, Tenant shall remove such alterations, additions, improvements, trade fixtures, personal property, equipment, wiring, conduits, cabling, and furniture (including Tenant's Off-Premises Equipment) as Landlord designated in writing for removal as part of or in connection with Landlord's approval of any applicable plans (including, without limitation, Tenant's Working Drawings, as set forth in Exhibit D and/or Exhibit J attached hereto (but Landlord shall not unreasonably require removal of customary office fIXtures and improvements)); however, Tenant shall not be required to remove any additions, fIXtures or improvements to the Premises or the Complex if Landlord has not specifically elected in writing that the improvement or addition in question needs to be removed. Tenant shall repair all damage caused by such removal. All items not so removed shall, at Landlord's option, be deemed to have been abandoned by Tenant and may be appropriated,sold, stored, destroyed, or otherwise disposed of by Landlord without notice to Tenant and without any obligation to account for such items; any such disposition shall not be considered a strict foreclosure or other exercise of Landlord's rights in respect of the security interest granted under Section 20. The provisions of this Section 21 shall survive the end of the Term.

22. Holding Over.

(a) Holdover Remedies. If Tenant fails to vacate the Premises at the end of the Term, Tenant shall be a tenant at sufferance and, in addition to all other damages and remedies to which Landlord may be entitled for such holding over, (a) Tenant shall pay, in addition to the other Rent, Basic Rent equal to 150% of the Rent payable during the last month of the Term, and (b) Tenant shall otherwise continue to be subject to all of Tenant's obligations under this Lease. The provisions of this Section 22(a) shall not be deemed to limit or constitute a waiver of any other rights or remedies of Landlord provided herein or at law. If Tenant fails to surrender the Premises upon the termination or expiration of this Lease, in addition to any other liabilities to Landlord accruing therefrom, Tenant shall protect, defend, indemnify and hold Landlord harmless from all loss, costs (including reasonable attorneys' fees) and liability resulting from such failure, including any claims made by any succeeding tenant founded upon such failure to surrender, and any lost profits to Landlord resulting therefrom.

(b) Seventy-Five Percent of Initial Premises. If, and only if, Tenant is leasing more than seventy-five percent (75%) of the entire initial Premises (based on a per rentable square foot basis), and Tenant fails to vacate the Premises at the end of the Term, Tenant shall be a tenant at sufferance and, in addition to all other damages and remedies to which Landlord may be entitled for such holding over, then during the first three (3) calendar month period of such holdover (and only during such first three (3) calendar month period), as Landlord's sole and exclusive remedy, (a) Tenant shall pay Basic Rent and Additional Rent in the amounts payable immediately prior to the end of the Term, and (b) Tenant shall otherwise continue to be subject to all of Tenant's obligations under this Lease. The provisions of this Section 22(b) (other than the proviso in the immediately preceding sentence) shall not be deemed to limit or constitute a waiver of any other rights or remedies of Landlord provided herein or at law. Except for the first sentence of this Section 22(b), for the first three (3) calendar month period of a holdover, if Tenant fails to surrender the Premises upon the termination or expiration of this Lease, in addition to any other liabilities to Landlord accruing therefrom, Tenant shall protect, defend, indemnify and hold Landlord harmless from all loss, costs (including reasonable attorneys' fees) and liability resulting from such failure, ... including any claims made by any succeeding tenant founded upon such failure to surrender, and any lost profits to Landlord resulting therefrom. For the avoidance of confusion, if Tenant is leasing more than seventy-five percent (75%) of the entire initial Premises (based on a per rentable square foot basis), and Tenant fails to vacate the Premises at the end of such first three (3) calendar month period of a holdover, the provisions of this Section 22(b) shall no longer be applicable and the provisions of Section 22(a) shall automatically apply.

23. Certain Rights Reserved by Landlord. Provided that the exercise of such rights does not unreasonably interfere with Tenant's occupancy, access, rights, benefits or privileges of, to or from the Premises, Landlord shall have the following rights:

In addition to Tenant's right to update the list of Competitors from time to time herein, Landlord shall have an identical right to request Tenant's approval to remove any then-named competitor on Exhibit N that has expressed an interest in writing (which may be in the form of an email) (or has made a written inquiry [including a written inquiry through a broker], either of which written inquiries may be in the form of an email), or intends to lease or sublease space, in the Complex and Landlord believes in good faith may no longer be a competitor ofTen ant. Tenant shall review and approve, such approval not to be unreasonably withheld, conditioned or delayed, any such request by Landlord in the same manner and under the same terms of this Section 29 as if Tenant was "Landlord" hereunder.

accordance with the terms of this Section 29, Landlord shall not be entitled to lease space to such party; (ii) if Landlord has leased space to a party in the Complex (that was not a then-named Competitor specified on Exhibit N at the time such party leased space in the Complex), but later becomes a Competitor (x) in accordance with the terms of this Section 29, (y) through a merger, sale or similar transaction, and/or (z) by virtue of a sublease, assignment or similar transfer, then (1) nothing herein will be deemed or construed to prohibit such party from occupying such space in the Complex, (2) Landlord shall not be required to remove or terminate any such party from its occupancy in the Complex, (3) nothing will prohibit Landlord from permitting such party to expand its presence in the Complex (e.g., lease more space in the Complex) provided any such expansion right in the Complex was contained in the lease with such party before it became a Competitor hereunder, and (4) nothing will prohibit Landlord from renewing the term of the lease with such party, even if such renewal right was not contained in such party's lease before it became a Competitor; or (iii) Landlord shall not approve any sublease, assignment or similar transaction for which Landlord has the right of approval (including reasonable approval) if the result of such consent would be that a Competitor then-identified on Exhibit N would occupy the Complex, unless such Competitor identified on Exhibit N shall be removed from Exhibit N in accordance with the terms of Subsection (c) of this Section 29.

(e) Merger of Competitor. To the extent any of the then-listed Competitors on Exhibit N merges with or is taken over by another entity, is subsumed or otherwise changes its name, such successor entity shall be deemed a Competitor in the stead of such previously named and specified Competitor (and the previously named party will no longer be a Competitor). If Tenant has actual knowledge of such an event, Tenant shall endeavor to provide written notice of any such indirect change in the list of Competitors from time to time as applicable to Landlord.

(f) Personal Right. The provisions of this Section 29 are personal to Ciena Corporation and any Permitted Transferee that has assumed in writing all of Ciena Corporation's obligations under this Lease in its entirety, and may be exercised only by Ciena Corporation and such Permitted Transferee and not by any other assignee or other subtenant of Ciena Corporation.

After the Working Drawings have been approved, Landlord shall cause the Work to be performed in substantial accordance with the Working Drawings.

If the estimated Total Construction Costs are expected to exceed the Construction Allowance,

D - 2

Tenant shall be allowed to review the submitted bid from the Agent at Risk (and the applicable subcontractors) to value engineer any of Tenant's requested alterations. In such case, Tenant shall notify Landlord of any items in the Working Drawings that Tenant desires to change within three (3) business days after Landlord's submission thereof to Tenant. If Tenant fails to notify Landlord of its election within such three (3) business day period, Tenant shall be deemed to have approved the bids. Within five (5) business days following Landlord's submission of the initial construction bids to Tenant under the foregoing provisions, Tenant shall have completed both of the. following items: (a) finalized with Landlord's representative and the Agent at Risk, the pricing of any requested revisions to the bids for the Work, and (b) approved in writing any overage in the Total Construction Costs in excess of the Construction Allowance.

Landlord shall be solely responsible for the progress of the construction of the Work and for the quality or fitness thereof; provided, however, Tenant shall be liable for any damage to the Building caused solely by Tenant or any Tenant Party, and any such damage that is the sole cause of the delay in the completion of the Work will be a Tenant Delay. Landlord shall obtain all governmental permits and approvals relating to the performance of the Work. Landlord shall obtain a certificate of occupancy (or similar certification) for the Building 1 Premises prior to Tenant's occupancy of the Building I Premises, provided that such certification may be temporary in nature. .

5. Change Orders. Tenant may initiate changes in the Work. Each such change must receive the prior written approval of Landlord, such approval to be governed by the standards set forth in Section 3(c) above; however, if such requested change would materially adversely affect (1) Building 1's structure or Building 1's systems (including Building I 's restrooms or mechanical rooms), (2) the exterior appearance of Building 1, or (3) the appearance of Building 1's common areas or elevator lobby areas, Landlord may withhold its consent in its sole and absolute discretion. If Tenant requests any changes to the Work described in the Space Plans or the Working Drawings, then such increased costs and any additional design costs incurred in connection therewith as the result of any such change shall be added to the Total Construction Costs. Regardless of whether approved by Landlord, any change orders initiated by or on behalf of Tenant that cause a delay in the completion of the Work, will be a Tenant Delay; provided, however, at Tenant's written request, Landlord shall use commercially reasonable efforts to provide an estimate of any delays or additional costs associated with a requested change and Tenant shall have three

(3) business days (which three (3) business days shall not be a Tenant Delay) to specify whether it will elect to make such change or rescind such request (and if Tenant fails to specify the same prior to the expiration of such three (3) business day period Tenant will be deemed to have elected to have rescinded the request for such change).

6. Definitions. As used herein (or in the Lease related to the Work) "Substantial Completion," "Substantially Completed," and any derivations thereof mean the Work in the Building 1 Premises is substantially completed in substantial accordance with the Working Drawings, and either (as selected by Landlord) Landlord's architect or Tenant's architect shall have certified the same on a standard form AlA form 704 certificate or similar certification, and the Building 1 Premises and the immediate parking areas associated with Building 1 shall be usable and accessible and substantially free of debris and Landlord shall have obtained a certificate of occupancy or similar certification for the Building 1 Premises, which may be temporary in nature, provided that if Landlord cannot obtain such certificate of occupancy solely because of work or installations that will be performed by Tenant or Tenant's contractor(s) (e.g., Tenant's installation of trade fixtures or systems furniture), then Landlord shall be deemed to have obtained such certificate of occupancy. Notwithstanding the foregoing terms of this Section 6, Substantial Completion of the Work in the Building 1 Premises shall have occurred even though minor details of construction, decoration, landscaping and mechanical adjustments remain to be completed by Landlord, provided that the same do not materially interfere with Tenant's business operations. For the purpose of determining solely whether any of the Building 1 FF&E Condition, the Building 1 Data Center Space, and/or the Building 2 Lab Space, have achieved "Substantial Completion," the same will deemed to have occurred when the same is substantially completed in substantial accordance with the Working Drawings therefor, and either (as selected by Landlord) Landlord's architect or Tenant's architect shall have certified the same on a standard form AlA form 704 certificate or similar certification. If Landlord elects for Tenant's architect to make any such certification of substantial completion as aforesaid, then Tenant agrees to cause its architect to reasonably provide the same.

7. Walk-Through; Punchlist. When Landlord considers the Work in the Building I Premises to be Substantially Completed, Landlord will notify Tenant and, within three (3) business days thereafter, Landlord's representative and Tenant's representative shall conduct a walk-through of the Building 1 Premises and identify any

D - 3

necessary. touch-up work, repairs and minor completion items that are necessary for final completion of the Work. Neither Landlord's representative nor Tenant's representative shall unreasonably withhold his or her agreement on punchlist items. Landlord shall use reasonable efforts to cause the contractor performing the Work to complete all punchlist items within thirty (30) days after agreement thereon; however, Landlord shall not be obligated to engage overtime labor in order to complete such items.

8. Excess Costs. The entire cost of performing the Work (including design of and space planning for the Work and preparation of the Working Drawings and the final "as-built" plan of the Work, costs of construction labor and materials, including the Agent at Risk fee, the Agent CM Fee (defined below), the general conditions, liability insurance rates, builders' risk rates, construction manager/subcontractor CO percentages, and performance and payment bond rates (excluding any utility costs, electrical usage during construction, additional janitorial services, or excess construction costs due to Landlord negligence, breach of Lease or breach of the construction contract, which shall be Landlord's sole responsibility), general tenant signage, related ·taxes and insurance costs, licenses, permits, certifications, surveys and other approvals required by Law, architectural, engineering services, moving expenses, and the construction supervision fee referenced in Section 10 of this Exhibit, all of which costs are herein collectively called the "Total Construction Costs") in excess of the Construction Allowance (hereinafter defined) shall be paid by Tenant. Upon approval of the Working Drawings and the selection of the Agent at Risk, Tenant and Landlord shall work in good faith to agree to and to·execute a work order agreement reasonably prepared by Landlord which identifies such drawings and itemizes the Total Construction Costs and sets forth the Construction Allowance. For each scheduled draw of the Construction Allowance, Tenant shall pay a fraction of such draw, the numerator of which is the amount by which Total Construction Costs exceeds the Construction Allowance and the denominator of which is the Total Construction Cost and Landlord shall pay the balance of such draw (which Landlord portion shall be paid from the· Construction Allowance). After the entire Construction Allowance has been disbursed, Tenant shall pay to Landlord 100% of the amount by which Total Construction Costs exceed the Construction Allowance from time to time upon Landlord's request therefor (and in no event later than thirty (30) days after each such request).

Landlord shall engage a third party (the "Agent CM") to supervise the Work, make disbursements required to be made to the Agent at Risk, and act as a liaison between the Agent at Risk and Landlord and coordinate the relationship between the Work, the Buildings and the Buildings' Systems. The Agent CM shall receive a fee for its construction supervision services equal to three percent (3.00%) of all hard and soft construction costs related to the Work (excluding· any work performed solely by Tenant or personal property installed by Tenant for which Landlord has no supervisory or delivery responsibility hereunder or under the Lease) (the "Agent CM Fee"), which amount may, at Tenant's election, either be paid from the Construction Allowance or by the Tenant as set forth herein, provided that all such payments, whether from the Construction Allowance or from the Tenant shall, at Landlord's option be paid directly to the Agent CM and/or to the Landlord (for delivery to the Agent CM). Concurrently with each disbursement of the Construction Allowance from time to time, an amount equal to 3% of such disbursement shall be drawn from the Construction Allowance to fund the Agent CM Fee. After the entire Construction Allowance has been disbursed, Tenant shall pay all remaining portions of the Agent CM Fee from time to time upon Landlord's request therefor (and in no event later than thirty (30) days after each such request). Landlord's approval of any of the Space Plans, Working Drawings, and/or Work, as applicable, shall not constitute an implication, representation or certification that such work is in accordance with any statues, codes, ordinances or other regulations, the compliance with which is the responsibility of Tenant and its Architect and contractors.

Each party shall give writtennotice to the other within such ten (10) day period. If either Landlord or Tenant shall fail timely to appoint an Appraiser, then the single Appraiser appointed by one party shall proceed to make the determination of the Prevailing Rental Rate, in accordance with the terms and conditions therefor set forth in the preceding paragraph of this Exhibit.

Each party shall pay the fees and costs of the Appraiser appointed by it (however, if only one Appraiser is timely appointed, the parties shall share the fees and costs of such Appraiser equally) ..

(b) If the valuations taken as a whole vary by two percent (2%) or less of the higher value, then the Prevailing Rental Rate shall be the average of the two valuations. If the valuations (taken as a whole) vary by more than two percent (2%) of the higher value, the two Appraisers shall within ten (10) days after submission of the last appraisal report, appoint a third disinterested Appraiser who shall meet all the criteria set forth in this Exhibit as an Appraiser with the same qualifications set forth for the original two Appraisers described above. Such third Appraiser shall, within fifteen (15) days after the appointment, make a determination of which of the two (2) other Appraisers' valuation shows the more correct Prevailing Rental Rate and that valuation shall be binding upon Landlord and Tenant. All fees and costs incurred in connection with'the determination of the Prevailing Rental Rate by the third Appraiser shall be paid one half (Yz) by Landlord and one half (Yz) by Tenant.
