(A)Conditions to Exercise of Tenant's Rights. On the conditions (which conditions Landlord may waive by written notice to Tenant at any time) that (i) as of both the time that any portion of the Initial First Offer Space first becomes available and as of the Commencement Date in respect of such portion of the Initial First Offer Space, that no "Event of Default" (as defined in Section 7.1 of the Lease) of Tenant exists, (ii) as of the Commencement Date in respect of the Initial First Offer Space, Tenant has not assigned Tenant's interest in the Lease or subleased more than fifty percent (50%) of the Premises, except in either case to a Permitted Transferee (as defined in Section 5.6.l of the Lease), and (iii) as of both the time that any portion of the Initial First Offer Space first becomes available and as of the Commencement Date in respect of said portion of the Initial First

Offer Space, the Lease is still in full force and effect, Tenant shall have the Initial Right of First Offer to lease the Initial First Offer Space, as hereinafter set forth.

(B)Definition of Initial First Offer Space. For the purposes hereof, the "Initial First Offer Space" shall be defined as any separately demised space

(meaning thereby any space which has been separately demised imniediately prior to the date of Landlord's Initial First Notice (defined below) or which Landlord decides it desires to separately demise), (i) which is located on either Floor 4 or Floor 6 of the Building, (ii) which becomes available for lease (as hereinafter defined) during the initial lease-up of Floor 4 and 6, and (iii) which if leased to a third party would leave less than 20,000 contiguous rentable square feet on Floor 4 and Floor 6 in the aggregate remaining unleased (i.e., this condition (iii) would not be fulfilled by a lease of the last remaining space on either Floor 4 or Floor 6, so long as at least 20,000 contiguous rentable square feet remained unleased on the other floor).

(C)Definition of Available for Lease; Landlord's Initial First Notice. When the Initial First Offer Space becomes available for lease, as hereinafter defined, Landlord shall notify Tenant ("Landlord's Initial First Notice") of the availability of such space, which notice shall contain the size, location and date of availability of such Initial First Offer Space. For the purposes hereof, the Initial First Offer Space shall be deemed "available for lease" when Landlord has received a bona fide request for a proposal from a third party to lease said space.

IfTenant fails timely to give Tenant's Initial Response, then Tenant shall have no further right to lease the Initial First Offer Space except as set forth in Section 2.1.2 below, if applicable.

If Tenant notifies Landlord in Tenant's Initial Response that it may be interested in leasing the Initial First Offer Space so offered, Landlord shall provide the terms to Tenant ("Landlord's Initial Offer") within ten (10) business days of Tenant's Initial Response. Landlord's Initial Offer shall be based upon the Annual Fixed Rent, hereinafter set forth, and other business terms upon which Landlord is willing to lease such space, provided, however, that the term for which such

Initial First Offer Space shall he leased to Tenant shall be coterminous with the Term of this Lease.

(2)If Tenant leases the Initial First Offer Space during Lease Year I, Tenant shall pay Annual Fixed Rent therefor at the same per-rentable-square-foot amounts payable for the Premises during the Term of this Lease, and Base Taxes and Base Operating Expenses shall be as set forth in Section 1.1 hereof.

specified in Landlord's Initial Offer is the Annual Market Rent ("Rent Dispute"). For purposes hereof, the "Required Portion" shall be between 5,000 and 15,000 rentable square feet, as designated by Tenant in Tenant's Initial RFO Exercise Notice. If Tenant specifies a Required Portion that is less than the entire amount of such space, the location and layout of such Required Portion shall be determined by Landlord, in the exercise of its commercially reasonable judgment.

(4)If Tenant shall give Tenant's Initial RFO Exercise Notice that does not indicate a Rent Dispute, the same shall constitute an agreement to lease the Required Portion upon all of the same terms and conditions in this Lease, except

(i) to the extent inconsistent with the provisions of this Section 2.1.1, and (ii) to the extent inconsistent with snch other business terms set forth in Landlord's Initial Offer, and (iii) that the Annual Fixed Rent shall be the amount specified in

Landlord's Initial Offer, and although such agreement shall be self-executing, Tenant shall enter into an instrument in writing memorializing such leasing within thirty (30) days after submission thereof by Landlord.

(7)If Tenant timely gives Tenant's Rescission Notice, then Tenant's Initial RFO Exercise Notice shall be ofno further force and effect, and the provisions of Section 2.1.l(D)(IO) shall apply.

(5) IfTenant shall give Tenant's RPO Exercise Notice that does

indicate a Rent Dispute, the parties shall negotiate in good faith for a period of twenty (20) days ("Negotiation Period") to reach agreement ou the Annual Fixed Rent.

(8)IfTenant timely gives a Broker Determination Request, then the same shall constitute an agreement to lease the First Offer Space upon all of the same terms and conditions in this Lease, except (i) to the extent inconsistent with the provisions of this Section 2.1.2, and (ii) to the extent inconsistent with the business terms set forth in Landlord's Offer, and (iii) that the Annual Fixed Rent shall be the Annual Market Rent as determined by the broker determination; and although such agreement shall be self-executing, Tenant shall enter into an instrument in writing memorializing such leai;ing within thirty (30) days after submission thereof by Landlord.

Ifduring the Term said First Offer Space again becomes available for reletting, Landlord shall again offer to lease such First Offer Space to Tenant pursuant to the provisions of this Section 2.1.2 and the terms of this Section shall continue to apply to such First Offer Space.

(11) Landlord shall have no obligation to offer space to Tenant which

(12) months thereafter.

b. For portions of the Premises served by dedicated Main Check Meter(s), and for all Supplemental Check Meter(s) serving the Premises, Ten.ant's allocable share of electricity costs for the period ("Tenant's

Electricity Payment") shall be determined by multiplying the cost per kilowatt hour charged by the utility(ies) to

Landlord by the number of kilowatt hours utilized by Tenant for such period as indicated by the dedicated Main Check Meter(s) and Supplemental Check Meter(s) for Tenant's Premises.

c. For portions of the Premises served by shared Main Check Meter(s), the Tenant's Electricity Payment shall be determined by multiplying the cost per kilowatt hour charged by the utility(ies) to Landlord by the number of kilowatt hours utilized as indicated by such shared Main Check Meter(s), and multiplying such total cost by a fraction, the numerator of which is the rentable area leased to Tenant and the denominator of which is the total rentable area under lease to tenants served by such shared Main Check Meter(s); provided, however, that if Landlord shall reasonably determine

that the cost of electricity furnished to the Tenant at such portion of the Premises exceeds the amount being paid by Tenant, then Landlord shall charge Tenant for such excess and Tenant shall promptly pay the same upon billing therefor as Additional Rent lmder the Lease.

d. Where part or all of the rentable area on a floor bas been occupied for less than all of the period for which adjustments are being made, appropriate and equitable modifications shall be made to the allocation formula so that each tenant's allocable share of costs equitably reflects its period of occupancy, provided that in no

event shall the total of all costs as allocated to tenants (or to unoccupied space) be less than the total cost of electricity for snch floor for said period.

4. Tenant shall make estimated payments on account of Tenant's Electricity Payment, as reasonably estimated by Landlord, on a monthly basis at the same time and in the same mantier as Tenant's monthly installments of Annual Fixed Rent.

Said statement to be rendered to Tenant also shall show for such period the amounts already paid by Tenant on account of Tenant's Electricity Payment and the amount of Tenant's Electricity Payment remaining due from, or overpaid by, Tenant for the period covered by the statement. Ifsuch statement shows a balance remaining due to Landlord, Tenant shall pay same to Landlord on or before the thirtieth (30"') day following receipt by Tenant of said statement. Any balance shown as due to Tenant shall be credited against Annual Fixed Rent next due, or refunded to Tenant if the Lease Term has then expired and Tenant has no further obligation to Landlord. Payments by Tenant on

account of Tenant's Electricity Payment shall be deemed Additional Rent and shall be made monthly at the time and in the fashion herein provided for the

payment of Annual Fixed Rent.

5. All costs of electricity billed to Landlord through the central utility metering center other than the costs of tenant electricity allocated pursuant to the procedures established herein, shall be treated as part of the Operating Expenses for the Building for purposes of determining the allocation of those costs.

6. Landlord shall be responsible for the maintenance of the Main Check Meter(s) and Tenant shall be responsible for the maintenance of the Supplemental Check Meter(s).

(a) the proposed assignee or subtenant is a tenant in the Building or elsewhere on the Site or is in active negotiation with Landlord or an affiliate of Landlord for premises in the Building or elsewhere ou the Site or is not of a character consistent with the operation of a first-class office building (by way of example Landlord shall not be deemed to be unreasonably withholding its consent to an assignment or subleasing to any governmental or quasi­ govemmental agency). Notwithstanding the foregoing, Tenant may sublease all or a portion of the Premises (the "Subleased

Premises") to a tenant of the Building or elsewhere on the Site (the "Subtenant") if said Subtenant satisfies the following criteria:

The effective date of tennination specified by Tenant shall not be less than thirty (30) days nor more than forty-five (45) days after the date ofnotice of such termination.

Unless terminated pursuant to the foregoing provisions, this Lease shall remain in full force and effect following any such damage subject, however, to the following provisions.

such mortgagee or ground lessor to be applied to, or are insnfficient for, the restoration of the Building and if Landlord does not otherwise elect to restore the Bnilding, then Landlord shall give prompt notice to Tenant terminating this Lease, the effective date of which termination shall not be less than sixty (60) days after the date of notice of such termination.

Unless snch restoration is completed within one (1) year from the date of the casualty or taking, Tenant, as its sole and exclusive remedy, shall have the right to terminate this Lease at any time after the expiration of such one-year period until the restoration is substantially completed, such termination to take effect as of the thirtieth (30th) day after the date of receipt by Landlord of Tenant's notice, with the same force and effect as if such date were the date originally established as the expiration date hereof unless, within thirty (30) days after Landlord's receipt of Tenant's notice, such restoration is substantially completed, in which case Tenant's notice of termination shall be of no force and effect and this Lease and the Lease Tenn shall continue in full force and effect.

Ifaddition, if any damage by fire or other casualty during the last six (6) months of the Lease Term renders, or in Landlord's reasonable judgment is likely to render, the Premises untenantable for more than fifteen (15) consecutive business days, Tenant may, at its election, terminate this Lease by notice given to Landlord within thirty (30) business days after the date of such casualty, specifying the effective date of termination.

Ifeither party shall give such notice, then.tl1is Lease shall terminate as of the date of such notice with the same force and effect as if such date were the date originally established as the expiration date hereof.

Further, if so much of the Building shall be so taken that continued operation of the Building would be uneconomic as a result of the taking, Landlord shall have the right to terminate this Lease by giving notice to Tenant of Landlord's desire to do so not later than thirty (30) days after Tenant has been deprived of possession of the Premises (or such portion thereof as may be taken); provided that in the event of such termination, Landlord shall also terminate all oilier tenant leases in affected portions of the Building that contain similar termination rights. If Landlord shall give such notice, then this Lease shall terminate as of the date of snch.notice with the same force and effect as if such date were the date originally established as the expiration date hereof.

Should any part of the Premises be so taken or condemned during the Lease Term hereof, and should this Lease not be terminated in accordance with the foregoing provisions, and the bolder of any mortgage which includes the Premises as part of the mortgaged

premises or any ground lessor of any ground lease which includes ilie Site as part of the demised premises allows the net condemnation proceeds to be applied to the restoration of the Building, Landlord agrees that after ilie determination of the net amount of condemnation proceeds available to Landlord, Landlord shall use due diligence to put what may remain of the Premises into proper condition for use and occupation as nearly like the condition of the Premises prior to such taking as shall be practicable (excluding Tenant's Property).

If such net condemnation proceeds are not allowed by

such mortgagee or ground lessor to be applied to, or are insufficient for, the restoration of the Building and if Landlord does not oilierwise elect to restore the Building, then Landlord shall give prompt notice to Tenant terminating this Lease, the effective date of

which termination shall not be less than sixty (60) days after the date of notice of such termination.

Nothing contained herein shall be construed to prevent Tenant fromprosecuting in any condemnation proceeding a claim for the value of any of Tenant's usual trade fixtures installed in the Premises by Tenant at Tenant's expense and for relocation and moving expenses, provided that such action and auy resulting award shall not affect or diminish the amount of compensation otherwise recoverable by Landlord from the taking authority.

Landlord lawfully may, immediately or at any time thereafter, and without demand or further notice terminate this Lease by notice to Tenant, specifying a date not less than ten (I 0) days after the giving of such notice on which this Lease shall terminate, and this Lease shall come to. an end on the date specified therein as fully and completely as if such date were the date herein originally fixed for

the expiration of the Lease Term (Tenant hereby waiving any rights of redemption), and Tenant will then quit and surrender the Premises to Landlord, but Tenant shall remain liable as hereinafter provided.

(b) ff this Lease shall have been terminated as provided in this Article, then, to the extent permitted by applicable law, Landlord may, without notice, re- enter the Premises, either by force, summary proceedings, ejectment or otherwise, and remove and dispossess Tenant and all other persons and any and all property from the same, as if this Lease had not been made, and Tenant hereby waives the.

Amounts received by Landlord after reletting shall first be applied against such Landlord's expenses, until the same are recovered, and until such recovery, Tenant shall pay, as of each day when a payment would fall due under this Lease, the amount which Tenant is obligated to pay under the terms of this Lease (Tenant's liability prior to any such reletting and such recovery not in any way to be diminished as a result of the fact that such reletting might be for a rent higher than the rent provided for in this Lease); when and if such expenses have been completely recovered, the amounts received from reletting by Landlord as have not previously been applied shall be credited against Tenant's obligations as of each day when a payment would fall due under this Lease, and only the net amount

thereof shall be payable by Tenant. Further, amounts received by Landlord from such relettiug for any period shall be credited only against

obligations of Tenant allocable to such period, and shall not be credited against obligations of Tenant hereunder accruing subsequent or prior to such period; nor shall any credit of any kind be due for any period after the date when the Tenn of this Lease is scheduled to expire according to its terms.

Landlord agrees to use reasonable efforts to relet the Premises after Tenant vacates the same inthe event this Lease is te1minated based upon an Event of Default by Tenant hereunder.

less than the current fair market rent then prevailing for similar·office space in the Building.

(d) (i)    Landlord may elect, as an alternative, to have Tenant pay liquidated damages, which election may be made by notice given to Tenant at any time after

such tennination and whether or not Landlord shall have collected any damages as aforesaid, as liquidated final damages and in lieu of all other damages beyond the date of such notice. Upon such notice, Tenant shall promptly pay to Landlord, as liquidated damages, in addition to any damages collected or due from Tenant for any period prior to such notice and all expenses which Landlord may have incurred with respect to the collection of such damages, such a sum as at the time of the giving of such notice represents the amount of the excess, if any, of the total rent and other benefits which would have accrued to Landlord under this Lease from the date of such notice for what would be the then unexpired Lease Term if the Lease terms had been fully complied with by Tenant over and above the then fair market cash rental value (in advance) of the Premises for the balance of the Lease Term, both discounted to present value using six percent (6%) as the discount rate.

(ii)For the purposes of this Article, if Landlord elects to require Tenant to pay damages in accordance with the immediately preceding paragraph, the total rent shall be computed by assuming that Tenant's share of excess taxes, Tenant's

share of excess operating costs and Tenant's share of excess electrical costs would be, for the balance of the unexpired Term from the date of such notice, the amount thereof (if any) for the immediately preceding annual period payable by Tenant to Landlord.

(e) Incase of any _Event of Default, re-entry, dispossession by sunnnary proceedings or otherwise, Landlord may (i) re-let the Premises or any part or parts thereof, either in the name of Landlord or otherwise, for a term or terms which may at Landlord's option be equal to or less than or exceed the period which would otherwise have constituted the'balance of the Term of this Lease and may grant concessions, abatements or free rent to the extent that Landlord reasonably considers advisable or necessary to re-let the same and (ii) may make such alterations, repairs and decorations in the Premises as Landlord in its sole judgment considers advisable or necessary for the purpose of reletting the Premises; and the making of such alterations, repairs and decorations shall not operate or be construed to release Tenant from liability hereunder as aforesaid. Landlord shall in no event be liable in any way whatsoever for failure to re-let the Premises, or, in the event that the Premises are re-let, for failure to collect the rent under re-letting.

(f) The specified remedies to which Landlord may resort hereunder are not intended to be exclusive of any remedies or means of redress to which Landlord may at any time be entitled lawfully, and Landlord may invoke any remedy (including the remedy of specific performance) allowed at law or in equity as if specific

remedies were not herein provided for. Further, nothing contained in this Lease shall limit or prejudice the right of Landlord to prove for and obtain in proceedings for bankruptcy or insolvency by reason of the termination of this Lease, an amount equal to the maximum allowed by any statute or rule oflaw in effect at the time when, and governing the proceedings in which, the damages are

to be proved, whether or not the amount be greater, equal to, or less than the amount of the loss or damages referred to above.

7.2 Landlord's Default

Landlord shall in no event be in default in the performance of any of Landlord's obligations hereunder unless and until Landlord shall have failed to perfom1such obligations within thirty (30) days, or such additional time as is reasonably required to correct any such default, after notice by Tenant to Landlord properly specifying wherein Landlord has failed to perform any such obligation. The Tenant shall uot assert any right to deduct the cost ofrepairs or any monetary claim against the Landlord from rent thereafter due and payable, but shall look solely to the Landlord for satisfaction of such claim.

No payment by Tenant, or acceptance by Landlord, of a lesser amount than shall be due from Tenant to Landlord shall be treated otherwise than as a payment on account. The acceptance by Landlord of a clieckfor a lesser amount with an endorsement or statement thereon, or upon any letter accompanying such check, that such lesser amount is payment in full, shall be given no effect, and Landlord may accept such check without prejudice to any other rights or remedies which Landlord may have against Tenant.

8.3 Cumulative Remedies

Except as expressly provided in this Lease, the specific remedies to which Landlord may resort under the terms of this Lease are cumulative and are not intended to be exclusive of any other remedies or means ofredress to which Laudlord may be lawfully entitled in case of any breach or threatened breach by Tenant of any provisions of this Lease.

(a) That the execution thereof by Landlord, and the acceptance thereof by the holder of such mortgage or the ground lessor, shall never be treated as an assumption by such holder or ground lessor of any of the obligations of Landlord hereunder, unless such holder, or ground lessor, shall, by notice sent to Tenant, specifically otherwise elect; and

(b) That, except as aforesaid, such holder or ground lessor shall be treated as having assumed Landlord's obligations hereunder only upon foreclosure of such holder's mortgage and the taking of possession of the Premises, or, in the case of a ground lessor, the assumption of Landlord's position hereunder by such ground lessor.

Inno event shall the acquisition of title to the Building and the land on which the same is located by a purchaser which, simultaneously therewi1h, leases the entire Building or such land back to the seller thereof be treated as an assumption by such purchaser-lessor, by operation of!aw or otherwise, of Landlord's obligations hereunder, but Tenant shall look solely to such seller-lessee, aud its successors from time to time in title, for performance of Landlord's obligations hereunder subject to the provisions of Section 8.4

hereof.

If Tenant fails to timely give either a Tenant's Rescission Notice or a Broker Determination Request, Tenant shall be deemed

to have given a Tenant's Rescission Notice.

(C)Upon the giving of the Extension Exercise Notice by Tenant to Landlord exercising Tenant's applicable option to extend the Lease Term in accordance with the provisions of Section 8.20(B) above, and subject to Tenant's right to give a Rescission Notice as set forth in Section 8.20(B) above, then this Lease and the Lease Term hereof shall automatically be deemed extended, for the applicable Extended Term, without the necessity for the execution of any additional documents, except that Landlord and Tenant agree to enter into an instrument in writing setting forth the Annual Fixed Rent for the applicable Extended Term as determined in the relevant manner set forth in this Section 8.20; and in such event all references herein to the Lease Term or the Term of this Lease shall be construed as referring to the Term, as so extended, unless the context clearly otherwise requires, and except that there shall be no further option to extend the Lease Term beyond the Second Extended Term.

(1) year) and shall in either case provide for automatic renewals ilirough the date which is ninety (90) days subsequent to the scheduled expiration of this Lease (as the same may

The FL-600P floor box is designed for conference roams, auditoriums, courtrooms, churches and all general meeeting space with carpeted floors over concrete. This floor box handles power, audio, video, tefecommunications

and data in one elegant and practical box.

The FL-600P is not only UL and CUL Listed but has also passed the latest UL test for scrub water. Because of FSR's unique engineering and manufacturing ability, FSR boxes passed for carpeted floors as we// as tile and wood!

The lift-off section of the cover allows full access to internal connector plates and stored cables, and the smaller hinged cable access door flips back to create the cable exit.

When the box is not in use, the box is completely closed

allowing unencumbered travel in the area with only the hand-mitered, elegant carpet edge visible. The low profile edging is 114" high and is available in brass or aluminum.

Inside the box are two angled brackets which handle stan­ dard size plates -2 single, 1 triple, 1 six gang opening. All are isolated for maximum safety. The FL-600P is designed to handle the rigors of a floor environment and

still maintains flexibility and elegance.

Note: This box is not applicable for contact with grade (soil or gravel).
