NOW THEREFORE Landlord and Tenant hereby agree to the following: 1. TERMS. 1.1 Premises. (a) The "Premises" demised by this Lease shall be a portion of the Building (defined below) containing approximately 61,876 rentable square feet and consisting of the entire third (3rd) and fourth (4th) floors of the Building, as shown on Exhibit A-I, attached hereto and incorporated herein by reference, but shall be subject to modification as and to the extentlset forth in section l.l(d), below. The Premises shall be measured (based upon CAD drawings) using ANSIIBOMAZ65.1-1996 standards, and shall be subject to confirmation by Tenant's architect as provided below. The Building within which the Premises is located is a four (4) story ClasslA office building (sometimes referred to herein as the "Building") to be constructed in accordance rith this Lease at 500 Cranberry Woods Drive, Cranberry Township, Pennsylvania. The land upon which the Building is situated, which is described in Exhibit A-2 attached hereto and incorporated herein by reference, shall be referred to hereinafter as the ''Land.'' The Building and Land are sometimes referred to herein as the "Project". Tenant shall also have the right to use parking areas and Common Areas of the Project, subject to the terms and limitations of this Lease, appurtenant to its occupancy of the rentable portions of the Premises. No easement for light or air is incorporated in the Premises. The rentable area of the Building is 119,344 square feet. Subject to Sections 1.1.(b), 1.1.(c) and 1.1.(d), below, Landlord and Tenant hereby stipulate that the measurement of the Premises and Building is as stated in this Section l.l.(a). (b) Landlord and Tenant acknowledge that the fmallocation of demiS~g walls for that portion of the Premises which will be located on the second (2od)floor of the Buildfg may not be determined until after Lease execution. In addition, pursuant to Section 1.1.(d), belo" Tenant may increase the size of the Premises by up to an additional 15,000 square feet (or convert tiS Lease . 1

into a full building lease). Accordingly, and notwithstanding subparagraph 1.1(a), abore, to the contrary, not later than thirty (30) days after the date upon which Landlord and Tenant reach final agreement on the dimensions of the Premises, Landlord shall cause Landlord's Architect to perform a measurement of the Premises, using the then most current drawings of the Premises an~ applying ANSVBOMA Z65.1-1996 standards, so as to determine both the rentable area of the Premises and Building, and shall certify and deliver these calculations promptly in writing to Landlord an~ Tenant. Tenant, or its representatives, shall have the right to verify the measurements made by Landlord's Architect under this Section 1.1(b) through its own measurement, provided Tenant gives!notice of its intent to exercise such right within five (5) business days after receipt (or deemed receipt under Section 30, below) by Tenant of the calculations of Landlord's Architect under this Section 1.l(b) (failing which Tenant shall be deemed to have accepted the calculation of Landlord 's Archltect, and to have stipulated to the square footages referenced therein). If Tenant exercises such right, and its re-measurement discloses a discrepancy from the rentable square footages calculated by Landlord's Architect, then the square footage of rentable area of the Premises andlorthe Building, as a~plicable, shall be adjusted in accordance with Tenant's re-measurement unless Landlord disputes Je results of Tenant's re-measurement within five (5) business days after the same is delivered to Lahdlord in writing, in which event, prior to the re-measurement being considered effective, the question of such measurement shall be submitted to arbitration to a panel of three arbitrators in accordance with the commercial arbitration rules of the American Arbitration Association. In such event the initial two arbitrators on the panel shall be Landlord's Architect and an architect selected by Tenant, and the third arbitrator shall be an independent architect licensed in Pennsylvania and exPenjenCed in commercial office measurement under ANSVBOMA Z65 .1-1996 standards selected by t~e mutual agreement of Landlord's Architect and Tenant's Architect. The square footages of the Premises andlor the Building in dispute shall be deemed to be the average of the determinations of those two architects whose determinations are the closest, with the third to be disregarded. If the renthble area of the Premises andlor Building is increased or decreased in accordance with this Section 1.1(b), all Iprovisions of this Lease which are dependent on the measurement of the Premises andlor Building (as the case may be) shall be appropriately adjusted to reflect the revised measurement (such as, but not limited to, the Rent, Tenant's Share, the Allowance, etc.). (c) The final measurements calculated in accordance with Section 1.1(b] shall be certified by Landlord and Tenant, shall constitute the respective rentable areas of ea1h of the Premises and Building, and shall not be subject to readjustment or re-measurement except in the event of casualty or condemnation that requires a reconstruction or restoration of the Building or a part thereof, or by any contraction of the Premises (such as due to the exercise by Landlord bfaright of recapture provided for hereunder), in each case with such re-adjustment or re-measurement to be limited solely to the portion of the Premises or Building, as the case may be, directlyiaffected thereby). Upon determination and certification ofthe measurement in accordance with this Section 1.1, if the same differs from the square foot measurement stated herein, Landlord and Tenant shall execute an amendment to this Lease stipulating to the respective certified rentable areas of the Premises and Building, and making any other modifications which flow from suchl l 'revised measurement. 2

I 6. LATE CHARGES; INTEREST. 6.1 Late Charge. Tenant hereby acknowledges that late payment to LandlorJ of Base Rent or additional rent will cause Landlord to incur administrative costs and loss of in~estment Iincome not contemplated by this Lease, the exact amount of which will be extremely difficult to ascertain. If any Base Rent or additional rent due from Tenant is not received by Laddlord or Landlord's designated agent within ten (10) days after the date due, then Tenant shaEIpay to Landlord a late charge equal to five percent (5%) of such overdue amount; provided, however, Landlord agrees to waive the first such late charges arising during any Lease Year during Je Term, up to a maximum of three (3) such waivers during the Term, as long as Landlord receives such overdue Base Rent, additional rent, or other sum within ten (10) days after the date~andlord provides Tenant with a written notice that such payment of Base Rent, additional rent lor other charges is overdue. The parties hereby agree that such late charges represent a fair and reasonable estimate of the administrative cost that Landlord will inc~ by reas~n of Tenant's late pryme~t. Landlord's acceptance of such late charges shall not constitute a waiver of Tenant's default WIth respect to such overdue amount or estop Landlord from exercising any of the other ri~hts and remedies granted hereunder.

Landlord will investigate with the local utility providerrhether separate metering by the utility company is available for individual Building tenants or rhether separate measurement of electrical usage will be available solely through submetering (and if separate metering by the utility company is both economically feasible and permissible, Uandlord will, at Tenant's request, arrange for such separate metering as part of Landlord's TI~Ork). Irrespective of whether electrical service is separately metered, submetered or determined ough engineering surveys, Tenant shall nevertheless be responsible to pay all costs of electrica ~service to the Premises and to the HVAC units serving the Premises (including Tenant's Specialty ~ystems, if any). The payment of Costs of Electricity by Tenant is governed by Section 9, below, subject to the provisions of this Section 8.4. Landlord reserves the right, in connection with assesaing any charge to Tenant arising out of Tenant' s use of electricity (i) to install electrical meters or supmeters (at Landlord's expense if not installed as part of Landlord's TI Work) to determine Tenant's electrical consumption, or (ii) if the installation of electrical meters or submeters is impdcticable (as, for example, with the Base Building HVAC service) to determine Tenant's electrical consumption either (A) at Landlord's option, through the use of engineering surveys, which !surveys shall be based on the actual electrical consumption by all users of electricity in the Building, or (B) if Landlord elects not to cause such engineering surveys to be performed, based upon the!ratio of 17

metered electric usage in the Premises to the total metered electric usage in the occupied ~ortions of Building (and in both cases, to charge Tenant directly, as a Cost of Electricity under this Lease, for such electrical usage without mark-up). If applicable, any such engineering surveys will be conducted by a licensed third party engineer selected by Landlord whose findings I will be determinative except as hereafter provided, and such survey( s) will be conducted in accordance with reasonable and sound engineering practices. Tenant's Share of the cost of any such enJneering surveys shall constitute a Cost of Electricity under this Lease. The foregoing provision's of this Section 8.4 to the contrary notwithstanding, the parties agree to install submeters or Jlectrical measurement devices to determine the amount of electrical usage associated with Tenant's Specialty Equipment, which installation shall be performed at Tenant's expense (and which may belpaid for out of the TI Allowance). 8.5 Interruption in Service. Notwithstanding Section 8.3 of this Lease to the contrary, in the event Tenant is deprived of water, electricity, elevator service or HVAC service as a ~esu1tof the willful or negligent acts or omissions of Landlord or its management agent, or their respective agents, employees and contractors (an "Abatement Event"), for a period exceeding tpree (3) consecutive business days, and as a result thereof Tenant is unable to and does not in fact!conduct business from the Premises or any material portion thereof during the entirety of such pe~od, then from and after such third (3rd) consecutive business day after Tenant first notified Landlord of such Abatement Event, Tenant shall be entitled to abate its Rent obligations hereunder as to the ~remises or portion thereof which is not usable (and not used), on e pro-rata basis if the affected portion is less than all of the Premises, until such time as the water, electrical, elevator or HVAC service (as applicable) is restored, or Tenant recommences its use of the Premises (or such applicable portion) whichever first occurs. In addition, if an Abatement Event as described above continues forkt l period of thirty (30) consecutive days, as a result thereof Tenant is unable to and does not in fact conduct business from the Premises or any material portion thereof during the entirety of such period, and Landlord has failed to commence to take action to bring an end to such Abatement Event 1s of the end of such 30-consecutive day period (or is not pursuing such action with reasonable diligence after the expiration of such 30-consecutive day period), then Tenant shall thereafter have the i'mbediate right to terminate this Lease without penalty upon delivery of written notice of such terrnniation to Landlord. Other than the foregoing rental abatement, and limited right of termination, Uandlord shall have no monetary liability (such as for lost profits, business losses or other similar damages) to Tenant as a result of any interruption in services under this Lease. 9. COSTS OF ELECTRICITY AND EXPENSE INCREASES. 9.1 Defined, For each calendar year or portion thereof during the Term, Tenant shall pay as additional rent to Landlord (i) the cost paid by Landlord to the applicable utility company for all electrical service furnished to the Premises and to HVAC units serving the Premises (to thr extent such electrical charges are not billed directly to Tenant by, and paid directly by Tenant to, the applicable utility provider) (herein referred to as "Costs of Electricity") and (ii) Tenant's Share of an amount (hereinafter referred to as "Expense Increases") equal to the difference betweeJ: I 18

(A) Operating Costs (defined in Section 9.5, below) for such calendar1ear; and (B) Operating Costs for the Operating Costs Base Year (defined in Section 9.2, below). 9.2 Base Year. For all purposes hereof, the "Operating Costs Base Year" shall be Calendar Year 2003. 9.3 Estimated Payments. Tenant shall make monthly installment payments on an estimated basis toward (i) Costs of Electricity, and (ii) Tenant's Share of Expense IncreasfS, in an amount equal to one-twelfth (1112) of Landlord's estimate of Costs of Electricity and one-twelfth (1112) of Landlord's estimate of the Tenant's Share of Expense Increases for the theri-current calendar year. Tenant's obligation to make monthly installment payments toward Costs of Electricity shall commence on first (1st) day of the first (1st) month of the Term, and Tenant's obligation to make monthly installment payments toward Tenant's Share of Expense lncreakes shall not commence until the first (1st) day of calendar year 2004. The foregoing estimate(s) ishall be based on Landlord's reasonable estimate of Costs of Electricity and Expense Increases for suchIcalendar year (which shall not exceed 105% of the prior year's Costs of Electricity and Expense Increases in the absence of evidence that a larger estimate is warranted). Landlord shall ehdeavor to communicate such estimate to Tenant on or before the date Landlord provides Tenant fvith the Expense Statement referenced in Section 9.4, below, provided that until Landlord provides such estimate to Tenant, Tenant's estimated payments will be based upon the prior year's estimate. Ifat any time or times during such calendar year, it appears to Landlord that Costs of Electricity or Tenant's Share of Expense Increases for such calendar year will vary from Landlord's estimate by more than five percent (5%) on an annualized basis, Landlord may, by written notice tolTenant, revise its estimate for such calendar year and Tenant's estimated payments hereunder for sU9hcalen- dar year shall thereupon be based on such revised estimate. The foregoing notwithstanding, to the extent determined on the basis of submetering or measuring devices, Costs of Electricity ishall be paid by Tenant within thirty (30) days after Landlord's written invoice therefor, and shall be based upon Tenant's actual consumption at the actual cost charged for such electrical service by me utility provider. 9.4 Annual Reconciliation. Approximately one hundred twenty (120) days afte~the end of each calendar year after the Operating Costs Base Year, Landlord shall provide to Tenant a statement (the "Expense Statement") setting forth Costs of Electricity and Operating Costs Irorsuch calendar year and Tenant's Share of Expense Increases for such year, calculated in accordance with Section 9.1, above. Within thirty (30) days after the delivery of such Expense Statemend Tenant . . Ishall pay to Landlord any deficiency between (a) the sum of (i) the amount shown as Costs of Electricity for such calendar year and (ii) the amount shown as Tenant's Share of Expense acreases for such calendar year, and (b) any payments made by Tenant theret? in accordance with se+on 9.3, above. If the payments made by Tenant pursuant to Section 9.3 exceed the amount sho\\f in the Expense Statement as Costs of Electricity and as Tenant's Share of Expense Increases for such calendar year, the excess amount shall be applied against the next payment(s) of Base Rent or 19

additional rent corning due hereunder, unless the Lease shall have expired, in which event Ilandlord shall refund such excess at the time of its delivery of the Expense Statement. 9.5 Operating Costs. The term "Operating Costs" shall mean any and all expenses actually paid or incurred by Landlord in connection with the operation, management, ma0tenance and repair of the Building and the Land, and all easements, rights and appurtenances thereto, butIshall be subject to the limitations hereinafter set forth, and shall exclude certain expenses identified in Section 9.6, below.

In the alternative, to Je extent permitted thereunder, Landlord may exercise its right to terminate this Lease pursuant t~ Section 21.5, below.

Upon the giving of a notice of the termination of this Lease, this Lease (and all of Tenant's rights hereun~er other than those with respect to Landlord's post-termination obligations) shall immediately trrminate, 47

provided that, without limitation, Tenant's obligation to pay Base Rent and Tenant's Share of Expense Increases and Tax Increases (as well as any damages otherwise payable under this Section 24), shall survive any such termination and shall not be extinguished thereby. Upon the kiving of a notice of the termination of Ten ant's right of possession, all of Tenant's rights in and to pbssession of the Premises shall terminate but this Lease shall continue subject to the effect of this Sdction 24. Upon either such termination, Tenant shall surrender and vacate the Premises in the condition required by Section 26, and Landlord may re-enter and take possession of the Premises and all the remaining improvements or property and eject Tenant or any of the Tenant's subtenants, assignees or other person or persons claiming any right under or through Tenant or eject some and Jot others or eject none, all pursuant to legal process in the absence of an abandonment of the Prebses by Tenant. This Lease may also be terminated by a judgment specifically providing for tenbmation. Any termination under this section shall not release Tenant from the payment of any sumlthen due Landlord or from any claim for damages or Base Rent, additional rent or other sum previously accrued or thereafter accruing against Tenant, all of which shall expressly survive such termination. Upon such termination Tenant shall be liable immediately to Landlord for all costs Landlo1rdincurs in attempting to relet the Premises or any part thereof, including, without limitation, broker's commissions, expenses of cleaning and redecorating the Premises required by the reletting and like costs. Reletting may be for a period shorter or longer than the remaining Lease Term. ~o act by Landlord other than giving written notice to Tenant shall terminate this Lease. Acts of maintenance, efforts to relet the Premises or the appointment of a receiver on Landlord's initiative tp protect Landlord's interest under this Lease shall not constitute a constructive or other termination of Tenant's right to possession or of this Lease, either of which may be effected solely by an express written notice from Landlord to Tenant. On termination, Landlord has the right to reCOiler from Tenant as damages: (a) The worth at the time of award of unpaid Base Rent, Additional Rent and other sums due and payable which had been earned at the time of termination; plus (b) The worth at the time of award of the amount by which the unpaid Base Rent, Additional Rent and other sums due and payable which would have been payable after termination until the time of award exceeds the amount of such rent and other income received by Landlord in respect of the Premises during such time period; plus (c) The worth at the time of award of the amount by which the unpaid Base Rent, additional rent or other sums due and payable for the balance of the Lease Term after the. Itime of award exceeds the fair market rental value of the Premises for such period, taking into account then existing market conditions, any applicable time reasonably needed to relet the Premises and to construct leasehold improvements therein for a new tenant, and the costs associated tfterewith, and any other factors bearing on the likely net income which may be derived from a reletting of the Premises (and Tenant shall have the burden of proof with regard to establishing the fair rental value of the Premises for such period); I 48

(d) Any other amount necessary which is to compensate Landlord for damages actually incurred as a result of Tenant's Default, including, without limitation, any costs or expenses incurred by Landlord: (i) in retaking possession of the Premises; (ii) in maintaining, repairing, preserving, restoring, replacing, cleaning, altering, rehabilitating or performing leasehold improvements to the Premises or any portion thereof, including in connection with any reletting to a new tenant or tenants; (iii) for leasing commissions; or (iv) for any other costs necessary or appropriate to relet the Premises; plus I (e) At Landlord's election, such other amounts in addition to or in lieu of the foregoing as may be permitted from time to time by the laws of the State in which the Premises are located, provided the same are not duplicative of any other damage amounts I1 l ecovered to Landlord pursuant to clauses (a) - (d) above, or otherwise provided for herein. The "worth at the time of award" of the amounts referred to in Sections 24.2.2( a) and (b) is computed by allowing interest at the Default Rate on the unpaid rent and other sums due and payable from the termination date through the date of award. The "worth at the time of award" of the amounts referred to in Sections 24.2.2(c) shall be computed by reducing each amount determined to present value using a discount rate equal to the average yield to maturity of United States treasury notes having a maturity most closely corresponding to such time period, plus 100 basis points, expressed as a percentage rate. In lieu of the amounts recoverable in a lump sum by Landlord pursuant to clauses (b) and (c) of this Section 24.2.2, above, but in addition to the amounts specified in clauses (a), (d), and (e) (or any other portion of this Section 24), and subject in all events to Section 24.2.6, below, Landlord may, at its sole election, recover "Indemnity Payments," as defmedhereinbelow, from Tenant. Forpurposes ofthis Lease "Indemnity Payments" means an amount equal to the Base Rent, Additional Rent and other payments provided for in this Lease which would have become due and owing thereunder from time to time during the unexpired Lease Term after the effective date of the termination, but for such termination, less the Base Rent, Additional Rent and other payments, if any, actually collected by Landlord and allocable to the Premises. If Landlord elects to pursue Indemnity Payments in lieu of the amount recoverable in a lump sum by Landlord under clauses (b) and (c), above, Tenant shall, on demand, make Indemnity Payments monthly, and Landlord may sue for all Indemnity Payments at any time after they accrue, either monthly, or at less frequent intervals. Tenant further agrees that Landlord may bring suit for Indemnity Payments at or after the end of the Lease Term as originally contemplated under this Lease, and Tenant agrees that, in such event, Landlord's cause of action to recover the Indemnity Payments shall be deemed to have accrued on the last day of the Lease Term as originally contemplated. In no event shall Tenant be entitled to any excess of any rental obtained bylreletting over and above the rental herein reserved. Tenant waives redemption or relief from forfeiture under any other present or future law, in the event Tenant is evicted or Landlord takes possession of the Premises by reason of any default of Tenant hereunder. 24.2.3 Landlord may, with or without terminating this Lease, re-enter the Premises and remove all persons and property from the Premises; such property may be removed and stored in a public warehouse or elsewhere at the cost of and for the account of Ten ant, or, as otherwise 49

provided in this Lease, shall be deemed abandoned by Tenant, and may be disposed of by Landlord at Tenant's expense and free from any claim by Tenant or anyone claiming by, through or under Tenant. No re-entry or taking possession of the Premises by Landlord pursuant to this Secrion shall be construed as an election to terminate this Lease unless a written notice of such intention is given to Tenant. 24.2.4 Tenant, on its own behalf and on behalf of all persons claiming through or under Tenant, including all creditors, does hereby specifically waive and surrender any and all rights and privileges, so far as is permitted by law, which Tenant and all such persons might otherwise have under any present or future law (1) to the service of any notice to quit or of Landlord's intention to re-enter or to institute legal proceedings, which notice may otherwise be required to be given, except the foregoing shall not waive any notices required under Section 24.1, above (if any); (2) t6 redeem re-enter or repossess the Premises after Tenant's right of possession has been terminated by Landlord; and (3) to restore the operation of this Lease, with respect to any dispossession of Tenant by judgment or warrant of any court or judge,or any re-entry by Landlord, or any expiration or ter- mination of this Lease, whether such dispossession, re-entry, expiration or termination shall be by operation of law or pursuant to the provisions of this Lease. 24.2.5 In addition, upon the occurrence of any Default by Tenant, Landlord, at its option, may take all or any of the following actions upon written notice to Tenant: (i) Upon the occurrence of an Event of Default, either during the Term or any extension thereof, and also when and as soon as the Term hereby created or any extension thereof shall have expired or sooner terminated, it shall, after Landlord's giving written notice of its intent to do so to Tenant, be lawful for any attorney as attorney-in-fact for Tenant to file an agreement for entering in any competent court an action and to CONFESS JUDGMENT AGAINST TENANT and all persons or entities claiming under Tenant for the recovery by Landlord of possession of the Premises, for which this Lease shall be sufficient warrant; whereupon, if Landlord so desires, a writ of possession may issue forthwith, without any prior writ or proceeding whatsoever, and provided that, if for any reason after such action shall have been commenced the same shall be determined and the possession of the Premises shall remain in or be restored to Tenant, Landlord shall have the right, upon any subsequent default or defaults or upon the termination or expiration of this Lease, to bring one or more action or actions as hereinbefore set forth to recover possession of the Premises as aforesaid. In any such action of ejectment, Landlord shall first cause to be filed in such action an affidavit made by it or someone acting for it setting forth jilie facts necessary to authorize the entry of judgment, and, if a true copy of this Lease (and as to of the truth of the copy such affidavit shall be sufficient evidence) shall be filed in such action, it shall not be necessary to file the original as a warrant of attorney, any rule of court, custom or practice to the contrary notwithstanding.

HOLDOVER If Tenant shall, without the written consent of Landlord, hold over after the expiration of the Lease Term (hereinafter, an "unauthorized holdover"), Tenant shall be deemed to be a tenant at sufferance, which tenancy may be terminated immediately by Landlord as provided by applicable state law.

In the event of any expansion of the Premises pursuant to this Lease, Tenant will be allocated, for the applicable expansion space, a pro rata share of the remaining parking spaces available in the Building's parking facilities relative to other space in the Building (but excluding the Premises as initially leased pursuant hereto, and the parking spaces allocated to tlie initial Premises hereunder). 47.

However, Landlord shall not be responsible for any frequency interference which occurs between the Tenant's roof equipment and any similar equipment operated by other tenants of the Building on the roof (or elsewhere) to the extent such other tenant's equipment was installed on the roof (or elsewhere) prior to the date Tenant's equipment was installed (i.e., with respect to equipment installed in the future by Tenant after another tenant of the Building, if any, has installed roof equipment o1iherwise allowed hereunder), provided Landlord shall not grant any other tenant rights or access to ~e roof for similar communications equipment if such rights or access would (i)result in blockage of the line of sight approved for Tenant's initial installation of its roof equipment, or (ii) interfere with the ability of Tenant' s roof equipment to perform properly. Any dispute regarding the matters set forth in this Section 51.6 shall be referred to an independent engineer selected by Landlord, but reasonably approved by Tenant, for final determination. 52. EXPANSION OPTIONS. 52.1 Generally. 52.1.1 This Article 52 sets forth three (3) expansion options in favor ofTenantwithin the Building, which are hereinafter referred to collectively as Tenant's "Expansion Options". In addition, Section 52.5, establishes an additional expansion option in favor of Tenant that relates to certain parcels contiguous to the Land, which is intended to be established under an Option Agreement to be negotiated in the future between Landlord, Tenant and Mine Safety Appliances, Inc. ("MSA") in accordance with the business terms and parameters reflected in Exhibit E hereto and made a part hereofby this reference. Tenant shall be entitled to exercise its Expansion Options only at such time(s) as (i) the Lease is in full force and effect, (ii) Tenant is not then in Default of any of its obligations under this Lease (after expiration of applicable notice and cure periods, if any), (ill) Tenant and/or any affiliate of Tenant ("Tenant Affiliate") is occupying the entire rentable square footage initially leased hereunder at the time of such exercise, and (iv) Tenant is exercising such Expansion Option for its own use and occupancy (and/or that of a Tenant Affiliate). The first Expansion Option is a specific expansion option for approximately 10,000 square feet of rentable area contiguous to the Premises, to be designated by Landlord at the time of Tenant's exercise of such expansion option and made available by Landlord to Tenant no later than the last day of the 74

twelfth (12th) month of the Lease Term, all as more fully set forth in Section 52.2, below. The second Expansion Option is a right of first offer applicable to vacant space within the Building during the initial Lease Term, all as more fully set forth in Section 52.3, below. The third Expansion Option is a right of first refusal applicable to vacant space within the Building during the first twenty- four (24) months of the initial Lease Term, all as more fully set forth in Section 52.4, below 52.1.2 All rights created under this Section 52 are personal to Tenant, and shall not inure to the benefit of any sublessee or assignee of Tenant (other than a Tenant Affiliate or a permitted assignee pursuant to Section 21.4 of this Lease), but rather, shall be deemed null and void and of no further legal force and effect immediately upon any assignment of this Lease other than as permitted as a matter of right pursuant to Section 21.4, above. In no event shall Tenant have the right to exercise any Expansion Option on behalf of a subtenant, assignee or other third party other than a Tenant Affiliate, 52.1.3 Time is of the essence of all provisions of this Section 52. 52.2 Prime Expansion Option. 52.2.1 Subject to the terms and provisions of this Article 52, Tenant is hereby granted the option (the "Prime Expansion Option"), exercisable by Tenant on or before 5:00 p.m. EST on the last day of the sixth (6th) full calendar month of the Lease Term (the "Prime Expansion Exercise Deadline"), and upon not less than six (6) months prior written notice to Landlord, to lease up to approximately 10,000 rentable square feet of space in the Building (the "Prime Expansion Space") for an initial term coinciding with the balance of the Initial Term (the "Prime Expansion [l'erm"). The "Prime Expansion Space" shall be a space designated by Landlord that is located contiguous to the Premises (on the same floor of the Building) consisting of approximately 10,000 rentable square feet (Plus or minus five percent (5%», and will be available for delivery to Tenant within six (6) months after the Prime Expansion Option Notice (defined below). Tenant shall exercise the Prime Expansion Option by delivering a written notice to Landlord (the "Prime Expansion Exercise Notice") on or before the Prime Expansion Exercise Deadline (i) stating Tenant's unqualified election to exercise the Prime Expansion Option, (ii) designating the portion (up to the whole) of the Prime Expansion Space that Tenant is electing to lease (which designation shall be subject to Landlord's reasonable consent, and which shall be deemed to constitute the "Prime Expansion Space" once such designation is approved by Landlord), and (iii) shall attach a proposed space plan for the portion of the Prime Expansion Space so designated by Tenant. Landlord shall approve Tenant's designation ofless than all of the original Prime Expansion Space so long as the balance remaining after such designation constitutes Independently Leasable Space within the meaning of this Lease. The date upon which Landlord delivers possession of the Prime Expansion Space to Tenant in the condition contemplated under Section 52.2.2, below, is referred to herein as the "Prime Expansion Date". 52.2.2 Any leasehold created pursuant to Tenant's exercise of the Prime Expansion Option shall be upon substantially the same terms and conditions as this Lease, including the then current annual Base Rent per square foot of rentable area, the Operating Costs Base Year, the Real 75

Estate Tax Base Year, and the Lease Expiration Date; and the following additional provisions shall be applicable: (i) the Prime Expansion Term shall by its terms expire on the Lease Expiration Date so that the Prime Expansion Term and the Initial Term of this Lease coincide, (ii) from and after the Prime Expansion Date, the Premises shall be deemed to include the Prime Expansion Space; (Hi) Tenant's Share shall be modified to include the applicable percentage of the Building allocable to the Prime Expansion Space; (iv) Article 9 and 10 of this Lease shall be deemed amended mutatis mutandis to provide that Tenant will pay Expense Increases and Tax Increases with respect to the Prime Expansion Space on the same basis provided for herein; (v) Monthly Rent for the Prime Expansion Space shall commence on the earlier to occur of (A) the date Tenant commences actual occupancy of the Prime Expansion Space for purposes of conducting business operations therein; or (B) the Prime Expansion Date (such date, the "Prime Expansion Rent Commencement Date"); (vi) as of the Prime Expansion Rent Commencement Date, the total Monthly Rent due under this Lease shall be adjusted to account for the additional square footage of the Prime Expansion Space; (vii) the Renewal Option described in Section 50 shall also apply with respect to the Prime Expansion Space; (viii) the allowance and construction provisions set forth in Section 52.2.3, below (and by application thereof, Exhibit C of this Lease), shall apply to the Prime Expansion Space; (ix) the number of parking spaces to be allocated to the Prime Expansion Space shall be as determined under Section 46 of this Lease based on the square footage of the Prime Expansion Space; (x) the Guaranty shall apply to Tenant's lease of the Prime Expansion Space; and (xi) all other provisions of the Lease shall be deemed amended mutatis mutandis to apply to the Prime Expansion Space; provided, however, that Base Rent shall not be due or payable by Tenant on account of the Prime Expansion Space until the Prime Expansion Rent Commencement Date. 52.2.3 Tenant shall be granted an allowance for tenant improvements to be performed by Tenant with respect to the Prime Expansion Space in an amount equal to the product of (i) $21.00 per rentable square foot in the Prime Expansion Space, and (ii) a fraction, the numerator of which is the number of full calendar months remaining in the Initial Term as ofthe Prime Expansion Rent Commencement Date, and the denominator of which is the total number of full calendar months in the Initial Term. Such allowance shall be funded topay for (i) Tenant's share of applicable architectural fees for preparation of construction drawings ("Design Costs") for the Prime Expansion Space, (ii) permit fees associated with such work, and (iii) the cost of physical improvementsho such Prime Expansion Space, with any unused amount to be credited against Rent becoming due for the Prime Expansion Space (but in no event shall more than 20% of such allowance be credited against Rent, and any amount in excess of20% of the allowance which is not used for the items described in the preceding clauses (i), (ii) and (iii) shall be deemed forfeited by Tenant). Such allowance shall be funded substantially in accordance with the construction provisions of Exhibit C of this lJease as applied to such construction. The parties agree that the parties shall generally conform to the provisions of Exhibit C with respect to the design and construction of physical improvements to the Expansion Space, as if fully restated in this Section 52.2 (and subject to any specific modifications as to timing or other points of detail expressly set forth in this Section 52.2). 52.2.4 Promptly after Tenant's exercise of the Prime Expansion Option, Landlord shall prepare and Landlord and Tenant shall execute an amendment to this Lease confirming such exercise and incorporating the applicable terms of this Section 52. These provisions shall be self- 76

operative, and such amendment shall merely confmn in a separate written instrument the terms and provisions set forth herein. 52.2.5 If, for any reason, Tenant fails to exercise the Prime Expansion Option with respect to the Prime Expansion Space on or before the Prime Expansion Deadline, then the Prime Expansion Option shall terminate, and Landlord shall have the right (subject only to Tenan~'s Right of First Refusal as defined in Section 52.4, below) to lease the Prime Expansion Space to any person or entity, free from the effect of the Prime Expansion Option, on such terms as Landlord determines in its sole and absolute discretion. In addition, if Tenant elects to exercise the Prime Expansion Option with respect to less than all of the original Prime Expansion Space, then the Prime Expansion Option shall terminate as to the balance of the original Prime Expansion Space, and Landlord shall have the right (subject only to Tenant's Right of First Refusal as defined in Section 52.4, below) to lease the remainder of the original Prime Expansion Space not leased by Tenant to any person or entity, free from the effect of the Prime Expansion Option, on such terms as Landlord determines in its sole and absolute discretion. _ I 52.3 Right of First Offer. 52.3.1 Subject to the further terms of this Section 52.3, Tenant is hereby granted, solely during the original Initial Term hereunder, an ongoing right of first offer ("Right of First Offer") to lease space which is or becomes vacant in the Project (any space subject to this Right of First Offer being sometimes referred to herein as the "Offer Space"). 52.3.2 With respect to any Offer Space, Landlord will notify Tenant in writing, within a reasonable time after Landlord becomes aware that an Offer Space is or will become available for lease to the public, of the size, location and configuration of such Offer Space (including a space plan depicting its then current configuration), the date Landlord anticipates that it will be able to deliver possession thereof to Tenant, and of the terms and conditions upon which Landlord is willing to lease such Offer Space to Tenant, including the term, rental rate, base year, improvement allowance and other material business terms and conditions of such offer (such written notice, an "Offer Notice"). Within seven (7) business days after its receipt of any Offer Notice, Tenant shall notify Landlord in writing if it wishes to negotiate a lease for the Offer Space with Landlord (such notice, an "Expression of Interest").

If Tenant delivers an Expression of Interest to Landlord prior to expiration of the seven (7) business day period after Landlord 1sOffer Notice, then Landlord and Tenant shall promptly meet through their authorized representapves to negotiate in good faith the terms of a lease of the Offer Space that is mutually acceptable to them (but without obligation of any kind to reach agreement on any such terms, other than the obligation to proceed in good faith) for a period (the "Negotiation Period") expiring thirty (30) days after the 77

date of Landlord 's original Offer Notice. If Landlord and Tenant are able to reach agreement on the terms of a lease for the Offer Space during the Negotiation Period (which agreement may be in the form of a signed letter of intent incorporating all of the main business terms of such lease transaction) (such agreed terms, the "Approved Offer Terms"), then the execution and delivery of such agreement or letter of intent by both Landlord and Tenant shall constitute Tenant's irrevocable election to lease the applicable portion of the Offer Space on the business terms reflected within the Approved Offer Terms, and otherwise in accordance with the terms of this Section 52.3. 52.3.3 Within ten (10) business days after the parties reach agreement on Approved Offer Terms, Landlord shall deliver to Tenant a lease (an "Offer Lease") for such Offer Space having legal terms substantially consistent with the terms specified in this Lease, and business terms consistent with the Approved Offer Terms. Should the parties fail or be unable to reach agreement on Approved Offer Terms prior to expiration of the Negotiation Period, then this Right of First Offer shall terminate as to such Offer Space, Landlord shall have the right (subject only to Tenant's Right of First Refusal as defined in Section 52.4, below) to lease such Offer Space to any person or entity, free from the effect of the Right of First Offer, on such terms as Landlord determines in its sole and absolute discretion, and Tenant's Right of First Offer under this Section 52.3 as to such Offer Space shall thereafter be null and void. In addition, should Tenant fail to execute and deliver an Offer Lease within fifteen (15) business days after an execution draft of the same is provided to Tenant in accordance with (and consistent with the legal and business terms applicable under) this Section 52.3, then Tenant's right offirst offer under this Section 52.3 shall immediately be null and void, and of no further force and effect. 52.3.4 With regard to any Offer Lease, the following terms and conditions shall apply: (i) the Offer Lease shall have an initial term as provided under the Approved Offer Terms; (ii) annual Base Rent under the Offer Lease shall be calculated in accordance with the Approved Offer Terms; (iii) the Operating Costs Base Year and the Real Estate Tax Base Year shall be as described in the Approved Offer Terms; (iv) the Offer Lease shall provide for renewal options if and to the extent set forth in the Approved Offer Terms; (v) construction of tenant improvements to the Offer Space shall be handled in substantially the same manner as is provided for under Exhibit C of this Lease unless otherwise provided in the Approved Offer Terms; (vi) the determination of Tenant's Share under the Offer Lease shall be made on the same basis as that provided for herein; (vii) the payment of Expense Increases and Tax Increases under the Offer Lease shall be made on the basis described in the Approved Offer Terms; (viii) the payment of Rent under the Offer Lease (and the initial term of the Offer Lease) shall commence as and when provided for under the Approved Offer Terms; (ix) the Offer Lease shall not contain any expansion options, roof rights, generator rights or other similar special rights other than as provided for in the Approved Offer Terms; (x) the Offer Lease shall provide for a parking allocation as described in the Approved Offer Terms; (xi) the Guaranty shall apply to the Offer Lease; and (xii) unless otherwise specifically provided to the contrary in the Approved Offer Terms, the Offer Lease shall otherwise be on substantially the same terms and conditions of this Lease. 78

If Tenant fails or declines to provide a ROFR Exercise Notice to Landlord prior to the expiration of such three (3) business day period, Tenant shall be deemed to have waived its Right of First Refusal as to such ROFR Space, and Landlord shall have the right to lease the ROFR Space free from the effect of the Right of First Refusal on such terms as Landlord ultimately agrees to with the party which provided such LOI (or its affiliates), and Tenant's Right of First Refusal under this Section 52.4 as to such ROFR Space shall thereafter be null and void; provided (i) that if Landlord ultimately fails or declines to execute a lease for such ROFR Space with the party which provided such LOI or its affiliates (the "Prospective Tenant") within six (6) months after such date, then such ROFR shall be reinstated, but in no event past the twenty-fourth (24th)month of the Initial Term, and (ii) if Landlord and the Prospective Tenant negotiate modifications to the terms of their lease from that described in the ROFR Notice to the extent that the average annual net effective rent payable under the modified lease transaction is less than 90% of the average annual net effective rent payable under the terms described in the ROFR Notice, then Landlord shall be required to provide Tenant with an updated ROFR Notice reflecting all of the modified terms, including those not specifically related to the average annual net effective rent payable thereunder (such notice, a "Changed Terms Notice"), and . Tenant shall have the right, for a period of three (3) business days after its receipt of a Changed Terms Notice, to deliver to Landlord a ROFR Exercise Notice exercising Tenant's Right of First Refusal as to such ROFR Space in accordance with this Section 52.4. If Tenant delivers a ROFR Exercise Notice prior to the expiration of the applicable three (3) business day period described above in this Section 52.4.2, then the provisions of Section 52.4.3 (if such ROFR Notice is delivered prior to the end of the sixth full calendar month of the Initial Term) or Section 52.4.4 (ifsueh ROFR Notice is delivered after to the end ofthe sixth full calendar month of the Initial Term but prior to the end of the 24thfull calendar month of the Initial Term), below, shall be applicable. 52.4.3 A. If the ROFR Exercise Notice is delivered prior to the end of the sixth (6th) full calendar month of the Initial Lease Term, then the ROFR Space will be leased to Tenant through an amendment to this Lease, upon substantially the same terms and conditions as this Lease, 79

including the then current annual Base Rent per square foot of rentable area, the Operating Costs Base Year, the Real Estate Tax Base Year, and the Lease Expiration Date (which shall be coterminous with the Initial Term of this Lease), but subject to the following additional provisions: (i) the term of the lease for such ROFR space shall commence promptly after date of Landlord's delivery of the ROFR Space to Tenant in the condition required by this Section 52.4.3.A (such date, the "ROFR Delivery Date"); (ii) from and after the ROFR Delivery Date, the Premises shall be deemed to include the ROFR Space; (iii) Tenant's Share shall be modified to include the applicable percentage of the Building allocable to the ROFR Space; (iv) Article 9 and 10 of this Lease shall be deemed amended mutatis mutandis to provide that Tenant will pay Expense Increases Iand Tax Increases with respect to the ROFR Space on the same basis provided for herein; (v) Monthly Rent for the ROFR Space shall commence on the earlier to occur of (A) the date Tenant commences actual occupancy of the ROFR Space for purposes of conducting business operations therein, or (B) the ROFR Delivery Date (such date, the "ROFRRent Commencement Date"); (vi) as of the ROFR Rent Commencement Date, the total Monthly Rent due under this Lease-shall be adjusted to account for the additional square footage of the ROFR Space; (vii) the Renewal Option described in Section 50 shall also apply with respect to the ROFR Space; (viii) the allowance and construction provisions set forth in Section 52.4.3 .B, below (and by application thereof, Exhibit Cof this Lease), shall apply to the ROFR Space; (ix) the number of parking spaces to be allocated to the ROFR Space shall be as determined under Section 46 of this Lease based on the square footage of the Prime Expansion Space; (x) the Guaranty shall apply to Tenant's lease of the ROFR Space; and (xi) all other provisions of the Lease shall be deemed amended mutatis mutandis to apply to the ROFR Space; provided, however, that Base Rent shall not be due or payable by Tenant on account of the ROFR Space until the ROFR Rent Commencement Date. B. Tenant shall be granted an allowance for tenant improvements to be performed by Tenant with respect to a ROFR Space subject to this Section 52.4.3 in an amount equal to the product of (i) $2l.00 per rentable square foot in the ROFR Space, and (ii) a fraction, the numerator of which is the number of full calendar months remaining in the Initial Term as of the ROFR Rent Commencement Date, and the denominator of which is the total number offull calendar months in the Initial Term. Such allowance shall be funded to pay for (i) Tenant's share of applicable architectural fees for preparation of construction drawings ("Design Costs") for the ROFR Space, (ii) permit fees associated with such work, and (iii) the cost of physical improvement to such ROFR Space, with any unused amount to be credited against Rent becoming due for the ROFR Space (but in no event shall more than 20% of such allowance be credited against Rent, and any amount in excess of20% of the allowance which is not used for the items described in the preceding clauses (i), (ii) and (iii) shall be deemed forfeited by Tenant). Such allowance shall be funded substantially in accordance with the construction provisions of Exhibit C of this Lease as applied to such construction. The parties agree that the parties shall generally conform to the provisions of Exhibit C with respect to the design and construction of physical improvements to the ROFR Space, as if fully restated in this Section 52.4.3 (and subject to any specific modifications as to timing or other points of detail expressly set forth in this Section 52.4.3). c.

Lease Months 1-60 61-120 Base Rent $15.60/rsf $ 17.45/rsf Annual Base Rent $1,872,000.00 $2,094,000.00 Monthly Base Rent $156,000.00 I $174,500.00 53.4 If Tenant exercises the Full Building Option, then: (A) this Lease shall be converted to a "triple net" lease, meaning that (i) instead of paying Expense Increases as currently described in Section 9 of this Lease, Tenant shall instead, throughout the entire Term (commencing on the Commencement Date), pay Tenant's Share of Operating Costs on a net basis, that is, without reference to or deduction of Operating Costs incurred in the Operating Costs Base Year, with such payments to be made on an estimated basis subject to an annual reconciliation substantially as described in Section 9, but, again, on the basis of Tenant's Share of Operating Costs without reference to or deduction of Operating Costs incurred in the Operating Costs Base Year, and (ii) instead of paying Tax Increases as currently described in Section 10 of this Lease, Tenant shall instead, throughout the entire Term (commencing on the Commencement Date), pay Tenant's Share of Real Estate Taxes on a net basis, that is, without reference to or deduction of Real Estate Taxes incurred in the Real Estate Tax Base Year, with such payments to be made on an estimated basis subject to an annual reconciliation substantially as described in Section 10, but, again, on the basis of Ten ant's Share of Real Estate Taxes without reference to or deduction of Real Estate Taxes incurred in the Real Estate Tax Base Year; (B) all other provisions of this Lease which are based on the original "full service, net of electric" payment structure (including without limitation applicable provisions within the Renewal Option section, and references herein to Expense Increases and Tax Increases) shall be deemed amended mutatis mutandis to give effect to the foregoing conversion of this Lease from a full service, net of electric lease to a triple net lease; (C) all provisions of this Lease which are calculated or based upon, or calculated as a function of, the square footage of the Premises (such as the determination of Tenant's Share, Base Rent, the TI Allowance under Exhibit C, etc.) shall be modified to account for the increased square footage of the Premises; (D) for so long as Tenant continues to Lease the entire rentable square footage of the Building, Tenant's rights with respect to use of the Building's parking facilities, common areas, roof and other areas that had previously been non-exclusive by virtue of the multi-tenanting ofthe Building will be deemed to be exclusive to Tenant (and all applicable provisions of the Lease will be deemed amended, mutatis mutandis, to give effect to fact that Tenant is the sole tenant of the Building); (E) all Expansion Options in this Lease which relate to the balance of the Building shall be null and void; 83

(F) all additional costs associated with the expansion of the Premises, including additional design costs and construction costs, will be Tenant's responsibility, but may be paid for out of the TI Allowance; and (G) any delay in the design and construction of the Building or Premises caused by such expansion shall constitute a Tenant Delay hereunder. 54.

To the extent the issuance of an occupancy permit (or its equivalent) is denied as a result of any matter for which Tenant is responsible under this Lease (such as, but not limited to, the non-compliance of any Tenant Work with applicable legal requirements), the inability of Landlord to secure such occupancy permit under such circumstances shall not affect Landlord's ability to claim that it has achieved "Substantial Completion" of Landlord's Work.

Tenant agrees that, notwithstanding the fact that the Approved TI Plans may encompass and include systems furniture installation and that proper completion of such systems furniture installation may therefore be a requirement for issuance of a certificate of occupancy (or its equivalent) for the Premises (or any applicable phase thereof), all systems furniture installation shall be performed by Tenant as part of Tenant's Work. "Test-Fit Allowance" is an allowance to be provided by Landlord to Tenant in order to reimburse Tenant for certain preliminary design work being performed by Tenant's architect in connection with this Lease, and to be calculated by multiplying (i) fifteen cents ($0.15), by (ii) the number of square feet of rentable area in the Premises.

During the period of construction of the Improvements, Tenant shall have the right to participate in the budgeting for Landlord's TI Work, the preparation and administration of bid packages for Landlord's TI Work (including the approval rights more fully described in Part IV, below), and to attend and participate in progress meetings with the TI GC and Design Professionals, change order processing, fee submittals and close out (and Tenant will use all reasonable and diligent efforts not to interfere with, or cause delay in the performance of, Landlord's Work in connection with its exercise of such participation rights). E. Provisions Regarding Legal Effect of Tenant Delays and Force Majeure 1. Generally. The parties acknowledge that it is their intent to provide in this Exhibit C for a statement of what the legal effect is in the event there is any delay in the performance of Landlord's TI Work and the Base Building Improvements as a result of the acts, omissions or breaches of this Exhibit C and the Lease by Tenant and Tenant's Agents and/or by virtue of the occurrence of Force Majeure. This Section I.E is intended to better define the meaning and consequences of the term "Tenant Delay" for purposes of defining, limiting and excusing the responsibilities of Landlord hereunder, and in relation to responsibility for the timing and cost of performance of Landlord's Work. C-lO

2. Delay Caused by Tenant and Landlord. (a) "Tenant Delay" shall mean any actual delay in the performance (and, if applicable, completion) of Landlord's Work occasioned by anyone or more of the following causes; (i) any negligence, misconduct or interference of Tenant andlor Tenant's Agents, with respect to any aspect of the design, permitting and/or performance of Landlord's Work; (ii) any delay by Tenant in the preparation, review andlor approval of the TI Plans beyond the time period provided therefor in the Approved Design Schedule and/or this Exhibit C, including (A) the failure of Tenant to submit a Space Plan which complies with all requirements described in the definition of "Space Plan", by the date for such submission indicated on the Approved Schedule, (B) the transmission of revisions to such Space Plan by Tenant after submission, other than as part of the collaborativ~ process of resolving Landlord objections described in Section II.C.l.(a), below, (C) the failure of Tenant to submit appropriate TI Plans for the entire Premises by the date for such submission indicated on the Approved Schedule, (D) the transmission of revisions to the TI Plans by Tenant after submission, other than as part of the collaborative process of resolving Landlord objections described in described in Section II.C.(2), below, and (E) any failure of Tenant to comply with the Tenant's general design covenants set forth in Section LB, above; (iii) any change order initiated by Tenant or required by Tenant's failure to comply with this Exhibit C; (iv) any other breach by Tenant of its obligations under this Exhibit.c, including Tenant's obligation to fund Excess TI Costs as and when required under such . Section. (v) any failure to achieve Substantial Completion of Landlord's Work, or to obtain an inspection approval with respect thereto, to the extent caused by the failure of the TI Plans to comply with applicable Governmental Requirements; (vi) any failure to achieve Substantial Completion of Landlord's work, or to obtain an inspection approval with respect thereto, to the extent caused by delay in the performance of any Tenant Work or by the non-compliance of any .Tenant Work as performed by Tenant with applicable Governmental Requirements; and (vii) any other item which, under the terms ofthis Exhibit C or the Lease constitutes a Tenant Delay. (b) Without limitation, Tenant agrees that if a failure by Tenant to take a required action for a period of time after the date such action was required to be taken causes a cn

delay in Substantial Completion which exceeds the duration of Tenant's failure, then the length of the Tenant Delay shall be the longer period of time with respect to which Landlord's performance was delayed, and not the shorter period that corresponded to the duration of Tenant's failure; conversely, if Tenant's failure to take a required action for a period oftime after the date such action was required to be taken gives rise to delay in Substantial Completion which is shorter than the duration of Tenant's failure, then the length of the Tenant Delay shall be the shorter period of time with respect to which Landlord's performance was delayed, and not the longer period that corresponded to the duration of Tenant' s failure (the intent being that the measure of a Tenant Delay be made by reference to the number of days of actual delay in the performance of, or, if applicable, completion of, Landlord's Work). Landlord and Tenant agree that, typically, charging Tenant under this Exhibit C with the delay arising out of a Tenant Delay will be limited to circumstances where such Tenant Delays causes actual delay in the completion of Landlord's Work; but Tenant acknowledges that where a Tenant Delay adversely affects the timing of performance of Landlord's Work, such that Landlord elects in accordance with this Exhibit C to incur overtime charges or other additional costs, or take other measures involving additional cost, in order to stay within the parameters of the Approved Schedule (i.e., to catch up the number of lost days), the fact that the Tenant Delay did not ultimately have the effect of actually delaying completion of Landlord 's Work because of such measures taken by Landlord shall not be construed to relieve Tenant of its responsibility for the cost of Landlord having taken such additional measures (if reasonably justified), as and to the extent provided for herein. (c) (i) To the extent compliance by Landlord with any responsibility of Landlord under this Exhibit C is delayed or prevented due to any Tenant Delay, Landlord shall be excused from such satisfaction to the extent of such Tenant Delay, and any additional costs incurred by Landlord to complete such responsibility as a direct result of such Tenant Delay shall be Tenant's responsibility. Without limitation, Landlord shall not be responsible for any permitting delays, bidding delays, construction delays, delays in final inspections, etc., caused by Tenant Delay. In addition, any revisions to the Construction Documents required to achieve compliance thereof with any applicable Governmental Requirements, or to coordinate the Approved TI Plans appropriately with the Approved Base Building Plans, in either case caused by the failure or breach of the foregoing representations and covenants of Tenant shall be subject to Landlord's reasonable approval, and if approved, shall constitute a Base Building Change Order or a TI Change Order, as the case may be (and all costs and delays associated therewith shall be Tenant's responsibility). (ii) To the extent compliance by Tenant with any responsibility of Tenant under this Exhibit C (including its responsibility to deliver the Space Plan and TI Plans to Landlord as and when required herein) is delayed or prevented due to any Landlord Delay, Tenant shall be excused from such compliance to the extent of such Landlord Delay, and any additional costs incurred by Tenant to comply with such responsibility as a direct result of such Landlord Delay shall be Landlord's responsibility. Without limitation, Tenant shall not be responsible for any permitting delays, bidding delays, construction delays, delays in final inspections, etc., caused by Landlord Delay. In addition, any revisions to the Approved Plans required to achieve compliance .of the Approved Plans with any applicable Governmental Requirements, or to coordinate the Approved TI Plans appropriately with the Approved Base Building Plans, in either case caused by C-12

the failure of Landlord to comply with its general design covenants, above, shall be subject to Tenant's reasonable approval, and if the same requires a Base Building Change Order or a TI Change Order, as the case may be, the incremental additional cost (and delays) associated therewith shall be Landlord's responsibility. (d) (i) Landlord may not claim the benefit of a Tenant Delay unless Landlord notifies Tenant in writing of such Tenant Delay within five (5) business days after Landlord first becomes aware of its existence, which notice shall describe the nature of the event giving rise to the claim of Tenant Delay, Landlord's basis for claiming that the event in question constitutes a Tenant Delay, and, if practicable, Landlord's good faith estimate of the period of delay which will be caused by such Tenant Delay (such notice, a "Tenant Delay Notice"); provided, that if Landlord fails to give a Tenant Delay Notice within five (5) business days after Landlord first becomes aware of a Tenant Delay, the same shall not constitute an absolute waiver of Landlord's right to claim such Tenant Delay, but in such event, the Tenant Delay in question will be deemed to begin one (1) business day after the date of Tenant's receipt (or deemed receipt under Section 30 of the Lease) of such Tenant Delay Notice (irrespective of when the event giving rise to the Tenant Delay began). (ii) Tenant may not claim the benefit of a Landlord Delay unless Tenant notifies Landlord in writing of such Landlord Delay within five (5) business days after Tenant first becomes aware of its existence, which notice shall describe the nature of the event giving rise to the claim of Landlord Delay, Tenant's basis for claiming that the event in question constitutes a Landlord Delay, and, ifpracticable, Tenant's good faith estimate of the period of delay which will be caused by such Landlord Delay (such notice, a "Landlord Delay Notice"); provided, that if Tenant fails to give a Landlord Delay Notice within five (5) business days after Tenant first becomes aware of a Landlord Delay, the same shall not constitute an absolute waiver of Ten ant's right to claim such Landlord Delay, but in such event, the Landlord Delay in question will be deemed to begin one (1) business day after the date of Landlord's receipt (or deemed receipt under Section 30 of the Lease) of such Landlord Delay Notice (irrespective of when the event giving rise to the Landlord Delay began). 3. Force Majeure. (a) Landlord may not claim the benefit of a Force Majeure under this Exhibit C unless Landlord notifies Tenant in writing of such Force Majeure within five (5) business days after Landlord first becomes aware of its existence, which notice shall describe the nature of the event giving rise to the claim of Force Majeure, Landlord's basis for claiming that the event in question constitutes a Force Majeure, and, if practicable, Landlord's good faith estimate of the period of delay which will be caused by such Force Majeure (such notice, a "Force Majeure Notice"); provided, that if Landlord fails to give a Force Majeure Notice within five (5) business days after Landlord first becomes aware of a Force Majeure, the same shall not constitute an absolute waiver of Landlord's right to claim such Force Majeure, but in such event, the Force Majeure in question will be deemed to begin one (1) business day after the date of Ten ant's receipt (or deemed receipt under Section 30 of the Lease) of such Force Majeure Notice (irrespective of when the event giving rise to the Force Majeure began). The foregoing provision to contrary notwithstanding, in the case C-13

of Unusually Inclement Weather, Excessive Permitting Delays and similar types of Force Majeure which require some permitted period of delay to elapse before the cause in question is deemed to constitute a Force Majeure, Landlord shall be deemed to have become aware of the existence of the Force Majeure delay (and shall be required to sent a Force Majeure Notice in respect thereof to Tenant) only after Landlord has actual knowledge that the number of days of delay arising from such cause has exceeded the number of days of delay which must elapse in order for such event to constitute a Force Majeure. Byway of example, and not of limitation, Landlord shall not be required to send a Force Majeure Notice with regard to Unusually Inclement Weather, or in order to claim the benefit of a delay due.to Force Majeure in respect thereof, prior to the five (5) business days after Landlord has actual knowledge that the 15th day of such inclement weather has elapsed. (b) The provisions of this Exhibit C shall be construed fairly and as a whole (and the definitions of Tenant Delay and Force Majeure shall be construed in conjunction with each other) in those cases where delay in completion of items of Landlord 's Work for any phase ofthe Premises are caused in part by Force Majeure and/or in part by Tenant Delay. F. Timing. Landlord and Tenant acknowledge that all specific dates set forth in this Exhibit C, including the dates set forth in the Approved Schedule, the dates set forth for initial submission of the Space Plan and the TI Plans, and the dates set forth in Section Ill.C.(i) and (ii) (as dates upon which Tenant may have the right to terminate this Lease if certain events have not occurred by such dates), and all other dates derived therefrom in this Exhibit C, are predicated on the assumption that this Lease will be executed and delivered on or before November 30, 2001. Accordingly, and notwithstanding any provision of this Exhibit C to the contrary, in the event the Lease was not executed and delivered by Tenant on or before November 30, 2001, then (in addition to all other extensions which may be contemplated herein due to Landlord Delays, Tenant Delays and/or Force Majeure, if any) each such date referenced herein shall be deemed to have been extended one (1) day for each day elapsing between November 30, 2001 and the date upon which the Lease is executed and delivered by Tenant. II. LANDLORD'S WORK A. Landlord's Base Building WorklDesign Covenants. Upon completion thereof, Landlord shall submit to Tenant (for use in the preparation of the TI Plans) the Base Building Plans at approximately the same time as the same are submitted for approval with the Township, in accordance with the Approved Design Schedule. B. Landlord's Base Building Worlc/General Performance Covenants. Promptly after the later to occur of (i) the issuance of permits for the applicable portions of Landlord's Base Building' Work, and (ii) Landlord's entry into the Base Building Construction Contract, which Landlord covenants to do promptly after selecting the Base Building GC in accordance with the Approved Schedule, Landlord will cause Landlord's .Base Building Work to be commenced, completed, installed or performed, as the case may be, in accordance with the Approved Base Building Plans and the Approved Schedule, subject to variations as described below, and any modifications required C-14

by applicable governmental authorities in review of the Approved Base Building Plans as part of the process of obtaining a building permit. During construction of the Building, Landlord shall have the right to make substitutions of material(s) of equivalent grade and quality, and to make changes necessitated by conditions met in the course of construction. C. Landlord's TI WorkiDesign and General Performance Covenants. (1) Preparation of Plans and Specifications for Tenant Improvements. (a) On or before the date indicated for such submission on the Approved Design Schedule, Tenant shall submit to Landlord for Landlord's review and approval Tenant's proposed Space Plan for the Tenant Improvements, which Space Plan shall, at a minimum, comply with all requirements described in Section LA, above, under the defmition of "Space Plan", and which shall be in a form that, if Landlord had no objections thereto, could constitute the Approved Space Plan under this Exhibit C. Should Landlord have objections to Tenant's proposed Space Plan, or any portion thereof, the parties shall use prompt, good faith and diligent efforts to resolve all such objections through a collaborative process involving time frames for responses to each others proposals and objections that is reasonably calculated to achieve final agreement on the Approved Space Plan as soon as is reasonably possible after its initial submission, and in all events no later than the date indicated for such approval on the Approved Design Schedule. (b) Promptly after the parties reach agreement on the Approved Space Plan, Tenant shall cause Tenant's Architect to prepare the TI Plans consistent with the Approved Space Plan and otherwise in compliance with all Governmental Requirements, and, on or before the date indicated for such submission on the Approved Design Schedule, Tenant shall submit the completed TI Plans for the entire Premises to Landlord for approval. Without limitation, if the parties are unable to reach agreement on the Approved Space Plan On or before the date indicated for such submission on the Approved Design Schedule, as a result ofa delay caused by Landlord's breach of its design covenants herein, then the time period within which Tenant is required to submit TI Plans under this clause (b) shall be deemed extended one day for each such day of such delay in reaching agreement on the Approved Space Plan which was caused by such breach. (2) Approval of and Revisions to Plans and Specifications. As soon as practicable after receipt of the TI Plans, but in no event more than ten (10) days after receipt thereof, Landlord shall either approve such proposed TI Plans (which approval shall not be unreasonably withheld), in which event the same shall thereupon constitute the Approved TI Plans, or shall return such TI Plans to Tenant with its objections or suggested modifications. If Landlord sends objections or proposed modifications to Tenant, and Landlord's modifications are acceptable to Tenant, said TI Plans shall thereafter be revised by Tenant's Architect to reflect the applicable changes, and the same shall be resubmitted to Landlord for approval within five (5) days after Tenant's receipt of Landlord's objections or suggested modifications.

In all events, Tenant shall deliver revised TI Plans to Landlord prior to the expiration of such five (5) day period, and Landlord shall grant its approval or disapproval thereto, and/or state any further objections or proposed modifications, within five (5) days after receipt thereof. After the first submission and resubmission, Landlord and Tenant agree to restrict objections and disputes to matters which have not previously been agreed upon or accepted by the other party, and deliver revised submissions. or objections within a five (5) day period, and to continue the collaborative process described above. The parties shall attempt to reach agreement .as soon as possible, and, in all events, within thirty (30) days after the date upon which Landlord received Tenant's first submission ofTI Plans. The process of submissions and resubmissions shall continue thereafter until final agreement is reached. Each party agrees that its failure to respond to a submission or resubmission within the above-referenced time frames shall constitute such party's acceptance of the submission or resubmission in question.

Any change order approved pursuant to this subparagraph is referred to herein as a "TI Change Order." (5) Tenant's Inspection Right. Subject to the insurance requirements set forth herein, and to reasonable safety restrictions, and reasonable prior notice to Landlord (so that Landlord can coordinate such entries with the Base Building GC and/or the TI GC), Tenant shall have the right to enter the Premises for purposes of inspecting Landlord's TI Work. To the extent any entry of Tenant or Tenant's Agents within the Premises prior to Substantial Completion interferes with the orderly progress of construction of Landlord's Work, Tenant shall cause such interference to cease immediately; and any delays in the Substantial Completion of Landlord ' s Work caused by such interference shall constitute a Tenant Delay hereunder. Access for such purposes shall not be deemed to constitute possession or occupancy .. In no event may Tenant, Tenant's Representative, Tenant's Architect, Tenant's Engineer or any other party within the Premises as Tenant's invitee have the right to direct the TI GC or the Base Building GC as to any matter relating to Landlord's Work, and all such concerns shall be directed to Landlord's Representative for coordination with the applicable contractor.

(a) Landlord shall be obligated to provide Tenant with written notice of its intent to tender possession of the Premises not less than three (3) calendar days prior to the date Landlord anticipates that it will tender possession thereof to Tenant in accordance herewith (such notice, a <C3-DayNotice"). The purpose of the 3-Day Notice is so that the parties can schedule a walk-through on or before the date of tender of possession thereof (and Landlord and Tenant each agrees to make itself available for the walk-through on the third (3rd)day after the 3-Day Notice). Within three (3) days after Landlord delivers the 3-Day Notice, Tenant's Representative and Landlord's Representative shall schedule and participate in a joint inspection of the Premises, for purposes of (i) conferring about what, if any, items must be completed in order to achieve substantial .completion to the extent necessary for Tenant to perform its Furniture Installation on the date possession thereof is tendered to Tenant, and (ii) preparing a preliminary punch list with respect to such level of substantial completion, provided that the timing of such inspection and punch list preparation shall not delay the timing applicable to any determination that substantial completion to the extent required to allow for tender of possession for purposes of Furniture Installation has occurred, except as more fully provided in subparagraph (b), below, if Landlord fails to deliver the 3-Day notice in a timely fashion. C-17

(b) Section 1.4 of this Lease contains provisions which set forth Landlord's and Tenant's respective rights and obligations in connection with the determination that Landlord's TI Work is Substantially Complete (including those relating to Tenant's right of inspection of the Premises, and Tenant's rightto dispute the correctness of Landlord's Certification of Substantial Completion). Reference is hereby made to Section 1.4 of the Lease for a complete recitation of such provisions, as if the same were fully repeated herein. (c) If, as a result of the aforementioned joint inspection(s), Tenant discovers Punch List Items (as the same is defined herein) that were not caused by Tenant Work, by Tenant, or by Tenant's Agents, Tenant shall promptly notify Landlord thereof; provided, however, that in the event of a dispute, Landlord and Tenant (and their respective Architects) shall negotiate in good faith with one another with the goal of completing preparation of an appropriate Punch List, and any dispute with the Base Building GC or TI GC (as the case may be) regarding the propriety of including any Punch List Items shall be handled in accordance with the applicable terms of the Base Building Construction Contract or the TI Construction Contract, as the case may be. The existence of such punch list items shall not postpone the Commencement Date of this Lease as to such phase of the Premises, nor the obligation of Tenant to pay Rent, additional rent or any other charges due under this Lease. (d) Landlord covenants and agrees to cause the Base Building GC or TI GC, as applicable, to promptly commence and diligently pursue the correction of all Punch List Items as soon as reasonably possible thereafter, and, subject to Force Majeure and any long lead items required for such correction, to complete the correction of all Punch List items within sixty (60) days after the Punch List is finalized. Landlord further covenants and agrees to repair or replace (or to cause the repair or replacement of) any defects in Landlord's Work as soon as reasonably practicable after Tenant provides notice thereof to Landlord; provided, however, Landlord shall have no obligation to pay the cost of any repair to (nor shall Landlord have liability to Tenant for defects in) Landlord's Work which are detected more than one (1) year after the date of Substantial Completion of Landlord 's Work; or in the case of any such defect previously repaired, first detected more thari six (6) months after the date of the last repair of such defect (unless the original one (1) year warranty period is longer than the applicable six (6) month period). The foregoing shall not affect, however, any of the general repair covenants set forth in the 'Lease, nor shall it apply to limit the warranty period provided for by the manufacturer or supplier with respect to any equipment incorporated into the Building or Premises, nor the warranty period otherwise provided for under the terms of the Base Building Construction Contract or TI Construction Contract, if such warranty period exceeds one (1) year. (8) Early Work and Furniture Installation (a) Landlord acknowledges that Tenant wishes to commence operations from the Premises as soon as possible after Landlord's Work is Substantially Complete, and that there are certain aspects of Tenant Work that need to be completed during the course of Landlord's performance of Landlord's Work. Accordingly, Landlord and Tenant acknowledge and agree that C-18

Tenant shall be given access to the Premises prior to the Substantial Completion of Landlord's Work, as and to the extent set forth herein, so that Tenant may perform certain items of Tenant Work, and thereby expedite Tenant's use and occupancy of the Premises. Any such items of Tenant Work shall be agreed upon in writing by Landlord and Tenant in their reasonable discretion prior to the commencement of any such work, and shall be referred to herein as the "Early Work", which shall include, without limitation, the installation of phone and data cabling, supplemental security systems, arid audio/visual systems in the Premises to the extent not included within Landlord's TI Work, and the installation by Tenant of Tenant's modular systems furniture even if shown in the Approved TI Plans. Landlord and Tenant acknowledge and agree that the installation of modular systems furniture in the Premises involves a higher degree of interference with the performance of Landlord's Work than is the case with wiring installations, and shall be referred to separately herein as the "Furniture Installation". Landlord and Tenant agree that the performance of any Early Work shall be in accordance with this paragraph IT.B(8). (b) Any entry to the Premises by Tenant for the purposes of performing any Early Work shall be subject to all of the terms and conditions of the Lease, except for the obligation to pay Base Rent and Additional (which will not be applicable until the Rent Commencement Date for the Premises, as provided in the Lease), provided Tenant will be responsible for the payment of utility expenses associated with Tenant's Early Work during such period. In addition, any entry by the Tenant or Tenant's Agents: (i) shall be subject to the reasonable insurance requirements of Landlord (which may incorporate the reasonable insurance requirements of the Base Building GC and the TI GC), and (ii) shall comply with any reasonable scheduling requirements of the Base Building GC or the TI Ge, as applicable (and, unless such entry is scheduled for within the Approved Schedule, Tenant shall contact Landlord's Representative at least two (2) full business days prior to Tenant's proposed time for such entry for Early Work so that Landlord's Representative can coordinate such entry and Early Work with the Base Building GC or the TI GC, as applicable; and Landlord shall use all reasonable efforts to accommodate such request as long as Tenant's proposed entry will not interfere with the orderly completion of Landlord's Work in accordance with the Approved Schedule). To the extent performance of Early Work by Tenant or Tenant's Agents, causes actual delay in the Substantial Completion of Landlord 's Work, the same shall constitute a Tenant Delay hereunder. In addition, Tenant shall bear the full risk of loss for any materials, equipment or other property which Tenant's personnel bring into the Building or the Premises in connection with any Early Work. (c) Landlord agrees to cause the Base Building GC and TI GC (and others) to cooperate in good faith with Tenant (and Tenant agrees to cooperate in good faith with Landlord) to accommodate Tenant's requested entry dates, and to otherwise use all reasonable efforts to enable the Tenant to have access to each floor of the Premises as soon as the commencement of Early Work becomes feasible. In furtherance of the foregoing, Landlord agrees that the construction schedule set forth in the TI Construction Contract will make provision for, and Tenant's Agents shall generally be permitted to gain, access to applicable phases of the Premises approximately forty-five (45) days prior to the date of Substantial Completion thereoffor purposes of data, telecom, security system and NY system wiring installations, and thirty-one (31) days prior to the date of Substantial C-19

Completion thereof for purposes of Furniture Installation, provided Tenant will continue to be responsible for unreasonable interruption of, disruption to, or interference with the performance of Landlord's Work in such areas as generally reflected in the Approved Schedule caused by its failure to appropriately coordinate the timing of Early Work by Tenant or Tenant's Agents therein so as to avoid such unreasonable interference, disruption or interruption. III. TIMING OF CONSTRUCTION A. Approved Schedule. Subject to Force Majeure and Tenant Delays, Landlord agrees to cause Landlord's Work to be Substantially Completed in accordance with the Approved Schedule. Landlord shall use reasonable efforts to notify Tenant of any material delays in the progress of construction that might prevent Substantial Completion of Landlord's Work in accordance with the dates set forth in the Approved Schedule (even if due to Force Majeure and Tenant Delays), together with an estimate of the duration of such delay, within a reasonable time period after Landlord becomes aware that such delays may prevent timely achievement of Substantial Completion by the dates provided for under the Approved Schedule. Landlord will, upon Tenant's written request, investigate with the GC if it is possible to mitigate such delay by accelerating the completion of Landlord's Work (through overtime and the like) in order to reduce or eliminate any anticipated delay, and, if so, Landlord and the GC will identify the cost which will be associated with accelerating the completion of Landlord's Work to the extent delayed thereby (or the portion thereof which is affected by such delay). If such acceleration is possible, Landlord will, in consultation with Tenant (and subject to Tenant's approval if the cost thereof is to be borne by Tenant), reasonably approve change orders allowing for such acceleration provided that, unless such delays occur as a result of a breach of Landlord's covenants under this Exhibit C, the cost of such acceleration shall be borne by Tenant (which may apply the TI Allowance thereto, or treat such costs as Excess TI Costs hereunder). B. Effect of Delay. To the extent any phase of Landlord's Work is not Substantially .Completed as of the dates indicated within the Approved Schedule, the following provisions shall apply: (i) If and to the extent Substantial Completion is delayed beyond the dates set forth in the Approved Schedule, but not beyond the Penalty Date, then the Commencement Date of this Lease shall be the date upon which Substantial Completion of Landlord's Work occurs, but such delay shall not otherwise result in or give rise to any damages or penalties payable by Landlord to Tenant, nor constitute a default by Landlord under this Lease; provided that to the extent such delay is caused by Tenant Delay(s), the Commencement Date of this Lease shall be deemed to be the date upon which Landlord's Work would have been Substantially Completed (and Tenant permitted to lawfully occupy the Premises) but/or such Tenant Delay(s), and Landlord shall not be liable to Tenant for any Rent abatement, damages, penalties or other rights and remedies as a result thereof. (ii) If and to the extent Substantial Completion is delayed beyond the Penalty Date, then: (A) If and to the extent such non-completion occurs as a result of C-20

any event of "Force Majeure", the Commencement Date ofthis Lease shall be the date upon which Substantial Completion of Landlord's Work occurs, but such delay shall not otherwise result in or give rise to any damages or penalties payable by Landlord to Tenant, nor constitute a default by Landlord under this Lease. (B) If and to the extent such non-completion occurs other than as a result of any Tenant Delays or Force Majeure, then (1) the Commencement Date of this Lease shall be the date of Substantial Completion of Landlord's Work, and (2) Tenant shall also be entitled to receive a credit against Base Rent (commencing on the Commencement Date, as adjusted pursuant to this subparagraph) in an amount equal to the sum of (a) product of (i) one (1) day's per diem Base Rent for the Premises as applicable for the first month of the Term, multiplied by (ii) the number of days elapsing between the Penalty Date and the date Substantial Completion is achieved by Landlord; and (b) an amount equal to the differential between the base rent normally payable by Tenant under that certain Sublease dated June 28, 2001 between Tenant and Danieili Corporation at Cranberry Woods I (the "Danieili Sublease") and any holdover rent actually paid by Tenant under the Danieili Sublease between the Penalty Date and the date Substantial Completion is achieved by Landlord. (C) If and to the extent Substantial Completion of any applicable phase of Landlord's Work is delayed as a result of any Tenant Delay(s), the Commencement Date of this Lease shall be deemed to be the date upon which Landlord's Work would have been Substantially Completed (and Tenant permitted to lawfully occupy the Premises) but for such Tenant Delay(s), and Landlord shall not be liable to Tenant for any Rent abatement, damages or other rights and remedies as a result thereof. (D) The provisions of clauses (ii)(A) , (B) and (C) shall be construed in conjunction with each other in those cases where delay in completion ofitems of Landlord's Work are caused in part by Force Majeure and in part by Tenant Delays. Except as set forth in Section Ill.C, below, the foregoing shall constitute the sole and exclusive remedies of Landlord and Tenant if Substantial Completion of Landlord's Work is delayed past the dates established therefor in the Approved Schedule. C. Additional Remedies.

IV. COSTS A. Payment of Costs. Except for TI Costs (for which Tenant shall bear sole financial responsibility subject to Landlord's obligation to fund the TI Allowance), Landlord shall be responsible for and shall pay when due all costs associated with the acquisition of the Land, the preparation of Construction Documents (excluding the TI Plans), and the performance of Landlord's Work in accordance with this Exhibit C. The foregoing notwithstanding, Tenant shall be entitled to a credit against the costs of Landlord's TI Work for which Tenant is financially responsible (including the TI Costs and costs of preparation of the TI Plans) in an amount equal to the TI Allowance. To the extent costs expended by Landlord to construct Landlord's TI Work, plus any Excess TI Costs, are less than the TI Allowance, the excess amount may be expended on costs associated the installation of data/voice cabling, security systems and other equipment integrated within the Premises or for Tenant Work (upon submission of invoices for the applicable work, including a letter from Tenant specifically approving such invoices and directing Landlord to pay a specified amount to a specified party, or requesting reimbursement for such expenses to the extent already paid by Tenant, together with certifications regarding completion (or partial completion) of such work by appropriate design professionals, lien waivers (to the extent reasonably applicable to the type of expense being funded) which may be partial or final lien waivers depending upon the status of completion, and satisfaction of other reasonable and customary funding requirements invoked by Landlord's lender(s) and (if applicable) equity funding sources); for moving expenses, legal expenses, systems furniture expenses or other similar expenses associated with Tenant's leasing of and move-in to the Premises (collectively, "Leasing Expenses"); and, if after such further application, the full amount of the TI Allowance still has not been utilized, Tenant be entitled to credit the unused amount against payments of Rent due under the Lease. To the extent the costs of Landlord's TI Work exceed the TI Allowance, the same shall constitute Excess TI Costs under this C-22

Exhibit c. B. Bidding. (1) Any reference in this paragraph IV.B to Tenant shall be deemed to refer to Tenant acting through Tenant's Representative after the completion of Construction Documents. After agreement upon the relevant portions of the Construction Documents, Landlord shall, with the assistance and cooperation of Tenant's Architect and Tenant's Representative, prepare one or more bidding packages for the different components of Landlord 's TI Work, based upon the Construction Documents. (2) After completion of such bidding package, Landlord shall (in consultation and cooperation with Tenant) commence a bid solicitation process for Landlord's TI Work on a competitive basis, in accordance herewith. Landlord will solicit bids for Landlord's TI Work from a minimum offour (4) general contractors, at least one of which will be Landlord's Base Building GC, and all of whom shall be subject to approval by both Landlord and Tenant. Tenant may designate at least three (3) general contractors to participate in such bidding process, subject to Landlord's reasonable approval. All general contractors submitting bids shall be licensed in Pennsylvania, have demonstrated ability to perform the work in a first class, good and workmanlike and timely manner (i.e., within the time frames established under the Approved Schedule), able to provide a payment and performance bond, required to provide in its schedule for performance of the applicable work time periods within which Tenant can perform Early Work and Furniture Installation as provided for herein, and each shall be subject to the consent of the other party, which shall not be unreasonably withheld, conditioned or delayed (and which shall be deemed given if the party whose consent is required does not object to an identified contractor within three (3) business days after the identity of such contractor is communicated to such party in writing). In the event that the Building (or any ownership interests therein) are owned by the Multi-Employer Property Trust or other union pension fund or retirement plan, then it shall also be a requirement that the general contractor and all subcontractors be signatories to the AFLiCIO. The bid solicitation will require the general contractors to competitively bid subcontracts for all major trades. Tenant may require that specific items of Landlord's TI Work be unit priced during the course of the bid process. Landlord agrees to cause each bidder to identify "long lead" items or materials which might delay Substantial Completion of Landlord's Work in accordance with the Approved Schedule, and shall notify Tenant of the same promptly after such identification can be made. If Tenant does not, prior to selection of the successful bidder, delete or modify any "long lead items" identified within the bid that is ultimately selected by Landlord and Tenant and replace same with alternative items (if any are available) that are not "long lead items", then Tenant will be deemed to have accepted such "long lead items" and any delay associated therewith, and any delay in Substantial Completion of a phase of the Premises occasioned by the continued inclusion by Tenant of such "long lead items" shall constitute a Tenant Delay under this Exhibit C. Landlord and Tenant shall cooperate in good faith to avoid such "long lead" items or materials, (3) All contractors shall submit their bids ("Bids") directly to Landlord, Tenant, and Tenant's Project Manager, each of whom will review and analyze all Bids submitted. Upon receiving all Bids or expiration of the bid submission period (as set forth in the bid solicitation), C-23

whichever first occurs, the parties shall have seven (7) days to review the Bids and request any clarifications thereof from the applicable bidders, including with respect to any long lead items (which request for clarification shall, in all events, be coordinated through Landlord, and is referred to as a "Request for Clarification"). If Tenant initiates a Request for Clarification, Landlord shall promptly commence diligent efforts to cause the information requested to be furnished, if possible. Within seven (7) days after receipt of the Bids from all qualified contractors, or, if one or more Requests for Clarification have been made, within five (5) days after receipt of the clarification requested (but in no event more than 15 days after the expiration of the bid submission period, as set forth in the bid solicitation) (the "Selection Deadline"), Landlord and Tenant shall select the qualified general contractor determined by Landlord and Tenant in good faith to be the acceptable bid ("Final TI Bid"), based upon a good faith review of all relevant considerations, including the relative bid prices, factors relating to the bidder' relative ability to perform (including other anticipated commitments and obligations of the bidders at such time), the ability of the bidders to coordinate effectively with the Base Building GC, any proposed changes to the form of construction contract attached to the bid solicitation, any other deviations from the qualifications established within the bid solicitation, past performance issues (if any) involving the respective bidders, subjective qualitative evaluations made in good faith by both Landlord and Tenant, and all other appropriate factors; and (i) the parties generally agree that the lowest priced bidder which meets the construction schedule, contractual requirements and other qualifications set forth in the bid solicitation shall be awarded the 11Construction Contract, and (ii) if Landlord and Tenant cannot reach agreement, despite their good faith efforts, on the bidder to whom the TI Construction Contract should be awarded, then Landlord shall be entitled to make the final determination unless Tenant agrees in writing to indemnify and hold Landlord harmless against the effects of all provisions of the bid which Tenant would designate for selection to which Landlord objects in good faith. No later than 5:OOp.m.,Eastern Time, on the Selection Deadline, Tenant shall indicate in writing its approval of the award of the Final TI Bid, and Tenant agrees (i) that Landlord shall not be obligated to proceed to negotiation of the final TI Construction Contract, nor the commencement of Landlord's TI Work, until such time as Tenant has delivered its written approval of the award of the Final TI Bid to Landlord, and (ii) any delay in Tenant's delivery of its written approval of the award of the Final TI Bid to Landlord beyond the Selection Deadline shall constitute a Tenant Delay under this Lease. Landlord shall notbe required to obtain Tenant's approval regarding the bidding or selection process with regard to any aspect of Landlord's Work other than Landlord's TI Work. (4) Promptly after selection of the TI GC for Landlord's TI Work, and Tenant's delivery of its written approval of the award of'the Final TI Bid to Landlord, Landlord will negotiate the terms of, and execute and deliver, a final TI Construction Contract with such TI GC in accordance with the Final TI Bid (and the pricing reflected therein), and the general form of construction contract attached to the bid solicitation for Landlord's TI Work as modified within the bidding process. Tenant shall have the right to review such contract prior to the bid solicitation, and to provide input and suggestions regarding the terms thereof, but the final determination of the form of such contract to be included in the bid solicitation, and to be executed with the TI GC, shall be made by Landlord, in Landlord's good faith judgment. (5) Landlord and Tenant shall endeavor to meet with each other and with the TI GC and the Design Professionals on a weekly basis to review design and construction issues for Landlord's TI Work at all times prior to Substantial Completion thereof. In conjunction with such C-24

meetings, Landlord will use diligent efforts to cause the TI GC: (A) to notify Landlord and Tenant of any scheduled government inspections of Landlord's TI Work so that each party, and its representatives, can be present therefor; and (B) to permit Tenant's Representative reasonable access to the Premises during the construction period, as necessary to conduct the inspections contemplated by this Exhibit C. (6) Tenant shall have the right to engage in value engineering during the course of any bidding process in order to reduce the Costs for which Tenant is responsible hereunder, provided that any actual delay in the comp letion of (or in reaching agreement upon) the Construction Documents, in the issuance of any permit for the construction of Landlord's Base Building Work or Landlord's TI Work (including as a result of modifications required to any plan submissions Landlord has made prior to such date with the Township), or in the completion of the bidding process, resulting from such value engineering by Tenant, shall constitute a "Tenant Delay" for all purposes of this Lease. C. Final Reconciliation. (1) Within sixty (60) days after final completion of Landlord 's TI Work, Landlord shall cause Landlord's Representative to provide Tenant with the Final Reconciliation and arrange to meet with Tenant to discuss the contents thereof. To the extent Landlord requires information in Tenant's possession in order for Landlord to prepare the Final Reconciliation, Landlord will promptly notify Tenant of the needed information, and Tenant agrees to provide such information to Landlord promptly after Landlord's written request specifying the information required to the extent in Tenant's possession, custody or control. Landlord's delivery of the Final Reconciliation shall be excused for so long as Tenant delays in providing information needed to complete same which is in Tenant's possession, custody or control to Landlord. If the Final Reconciliation indicates that the total cost to complete Landlord's TI Work exceeds the TI Allowance, then such excess shall constitute an Excess TI Cost for purposes of this Exhibit C and shall be payable by Tenant to Landlord within ten (10) business days after Landlord's written demand (to the extent not theretofore funded by Tenant). (2) If the Final TI Bid (or any combination of Tl Costs for which Tenant will be responsible hereunder) exceeds the TI Allowance, Landlord shall have the right to require payment from Tenant of the amount by which aggregate Excess TI Costs exceeds the T! Allowance prior to being obligated to proceed with the TI Work from which such Excess TI Costs are derived, which payment shall be made by Tenant to Landlord within ten (10) business days after Landlord's written demand accompanied by reasonable substantiating documentation, and which (ifbeingpaid to defray Excess Costs which are not yet due and payable to the contractor under the terms of the applicable construction contract) will be held by Landlord, in trust, to be disbursed pari passu with any amounts utilized by Landlord to make payments in respect of TI Costs. Any amounts paid by Tenant to Landlord under this provision shall be credited against such Excess TI Costs. D. First-Class Lien-Free Completion: Warranties. Except as specified in the Construction Documents, Landlord shall use only first class materials in connection with any Landlord Work. All Landlord Work shall be paid for in full and in a timely fashion by Landlord (subject to Tenant's obligation to fund Excess TI Costs as and to the extent set forth herein), and C-25

shall be performed in a lien-free, first-class, and good and workmanlike manner. Landlord shall either assign to Tenant, or enforce on Tenant's behalf, all warranties on Landlord's Work to the extent Tenant is responsible for the maintenance or repair of such items and the same would be covered by such warranties. V. TENANT WORK A. Generally. (1) All Tenant Work shall be performed in accordance with plans and specifications approved by Landlord, which approvals shall not be unreasonably withheld and shall generally be subject to the standards applicable to approval of Tenant alterations pursuant to Section 15 of the Lease (and Landlord agrees that it may not disapprove any item shown therein if Landlord would not have the right to disapprove such item under Section 15 if such item were a Tenant alteration), subject only to variations as described below, and any modifications required by applicable governmental authorities in review of the plans for such Tenant Work as part of the process of obtaining a permit therefor. During construction of Tenant Work, Tenant shall have the right to make substitutions of material(s) of equivalent grade and quality, and to make changes necessitated by conditions met in the course of construction, provided Tenant shall seek Landlord's approval of any material change to the plans for such Tenant Work within the scope ofthe aforesaid circumstances, which shall not be unreasonably withheld, conditioned or delayed, and which approval shall be deemed given if Landlord fails to respond within three (3) business days of a written request for approval. The procedure for submission of any plans and specifications for Tenant Work shall be substantially identical to (i.e., a reverse mirror image of) the procedure for obtaining Tenant's consent to the Approved Plans, unless the work in question does not require Landlord approval under the standards applicable to approval of Tenant alterations pursuant to Section 15 of the Lease, in which event Tenant shall still notify Landlord of the Tenant Work it is proposing to perform. Tenant agrees that Landlord will have the right to inspect the performance of Tenant Work by Tenant's contractor(s) and subcontractor(s), through a construction manager appointed by Landlord, and Tenant agrees to cooperate with Landlord to facilitate such inspection, including without limitation: (A) notifying Landlord and such construction manager of any scheduled government inspections of Tenant's Work so that Landlord's Representative can be present therefor; (B) permitting Landlord's Representative reasonable access to those portions of the Premises in which Tenant Work is being performed during the construction period, as necessary to perform such inspections, and (C) complying (or causing its contractor to comply) with the reasonable directions of Landlord's Representative in connection with Tenant Work, as long as such directions are not inconsistent with the approved plans for such Tenant Work, Landlord shall use all reasonable and diligent efforts not to interfere with the performance of any Tenant Work during the' course of any inspections by Landlord's Representative pursuant to this Paragraph. (2) Without limiting the generality or applicability of any provisions of this Exhibit C or the Lease, Tenant agrees that the following provisions shall apply to the performance of any Tenant Work: (i) In performing any plumbing work which may require removal offloor slab in corridors which are otherwise within the common areas of the Building, Tenant C-26

agrees upon completion of such plumbing work, to restore the finishes within such common corridors to their original condition. (ii) In performing portions of any Tenant Work which involve construction work upon the exterior of the Building, Tenant agrees that it shall, at Tenant's sole expense, restore all areas of the Building's exterior, including without limitation all adjacent planting areas, sidewalks and parking areas, affected by the execution of such Tenant Work, to their original condition upon the completion of such portions of such Tenant Work. (iii) Tenant shall protect and restore all work areas of the Building (including without limitation any portions ofthe common areas of the Buildings) utilized or affected in performing any Tenant Work, including, but not limited to, the Building roofs, common corridor floors, walls, and ceilings, floor penetrations and chase wall penetrations. Tenant shall use only roofing contractors who are permitted to perform such work upon the roof without nullifying any then applicable roof warranty for penetrations and reflashing of affected roof areas (if any), which roofing contractors shall be subject to Landlord's reasonable approval and which roofing contractors shall warrant to Landlord's reasonable satisfaction the integrity of any such roof or exterior penetrations and that the same are free from leakage and are otherwise properly waterproof. Tenant shall further ensure that all floor penetrations are properly fire-stopped, in accordance with applicable building and fire codes and prudent construction practices.

To the extent any Tenant Work affects, voids or otherwise nullifies or renders unenforceable any warranty on Landlord's Work, Tenant will be deemed to have underwritten such warranty directly. Tenant shall either assign to Landlord, or enforce on Landlord's behalf, all warranties on Tenant Work to the extent Landlord is responsible for the maintenance or repair of such items and the same would be covered by such warranties. The inclusion of provisions in this Paragraph IV.A(2) which impose obligations upon Tenant and/or Tenant's contractor with regard to the performance of any Tenant Work are intended only to apply to those portions of Tenant Work (if any) which are approved by Landlord; and the inclusion of such provisions shall not be construed to impose upon Landlord, or imply, any obligation to approve work proposed by Tenant. (3) Except as provided herein, Tenant shall obtain all necessary permits in connection with any Tenant Work, including all final inspection approvals which are required for the proper completion of such Tenant Work. Landlord shall cooperate with Tenant, at no out-of- pocket expense to Landlord, to facilitate the issuance of such permits and inspection approvals. C-27

ExmBITF Form of Guaranty of Lease GUARANTY OF LEASE THIS GUARANTY is given this _ day of December, 2001, by McKESSON CORPORATION, a Delaware corporation (the "Guarantor"), to TC NORTHEAST METRO, INC., a Delaware corporation (with its successors and assigns, "Landlord"). REC IT ALS: R-l. Landlord and McKesson Automation, Inc.(with its successors and assigns, "Tenant") wish to enter into a Lease Agreement of even date herewith, which lease, together with any and all modifications, amendments and extensions thereof is hereinafter referred to as the "Lease", pursuant to which Landlord will lease to Tenant certain premises (the "Premises") located within the building located at 500 Cranberry Woods Drive, Cranberry Township, PA (the "Building"), which building is owned by Landlord. R-2. Landlord is requiring that Guarantor execute and deliver this Guaranty as a condition to Landlord's executing and delivering said Lease. R-3. Tenant is a wholly owned subsidiary of Guarantor. By virtue of such corporate affiliation, Guarantor is willing to induce Landlord to enter into the Lease by guarantying Tenant's obligations under the Lease to the full extent set forth herein. WITNESSETH: NOW, THEREFORE, in consideration of Ten Dollars ($10.00) in hand paid, and of other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged by Guarantor and by Landlord, Guarantor, intending to be legally bound, does hereby agree as follows: 1. Guarantor hereby unconditionally and absolutely guarantees to the Landlord: 1.1.1 The full, prompt and complete payment by the Tenant of all Rent (as defined in the Lease) and other sums which are or may be payable by the Tenant under the Lease; and 1.1.2 The full, prompt and complete performance by the Tenant of all and singular the terms, covenants, conditions and provisions in the Lease required to be performed by the Tenant. Guarantor's obligations hereunder shall be in all instances effective without regard to any indulgence, forbearance, delay, neglect or failure on the part of Landlord in enforcing Tenant obligations under the Lease, and Guarantor hereby waives, to the fullest extent permitted by law, all defenses to enforcement of this Guaranty based upon the indulgence, forbearance, delay, neglect or failure by Landlord in enforcing Tenant's obligations under the Lease. In addition, the validity of this Guaranty and the obligation of Guarantor's hereunder shall in no way be terminated, affected or impaired by reason of the release or exchange of any security deposit or other collateral given by F-l

Tenant as security for the performance of Tenant's obligations under the Lease, all of which may be made, done, or suffered without notice to/or the consent of Guarantor. 2. Guarantor hereby waives notice of acceptance hereof and any and all other notices which by law or under the terms and provisions of the Lease are required to be given to the Tenant, and also waives any demand for or notice of default of the payment of rent and other sums which may be payable by the Tenant under the Lease and the performance of any and aU terms, covenants, conditions and provisions in the Lease required to be performed by the Tenant; and Guarantor further expressly hereby waives any and all legal obligation, duty or necessity for the Landlord to proceed first against the Tenant or to exhaust any remedy the Landlord may have against the Tenant, it being agreed that in the event of default or failure of performance in any respect by the Tenant under the Lease, the Landlord may proceed immediately, and have right of action, solely against Guarantor or against Tenant, or jointly against Guarantor and Tenant. 3. In the event of any bankruptcy, reorganization, winding up or similar proceedings with respect to Tenant, no limitation of Tenant's liability under the Lease which may now or hereafter be imposed by any federal, state or other statute, law or regulation applicable to such proceedings, shall in any way limit the obligation of Guarantor hereunder, which obligation is coextensive with Tenant's liability as set forth in the Lease without regard to any such statutory or legal limitation. Guarantor further agrees that the validity of this Guaranty and the obligations of Guarantor hereunder shall in no way be terminated, affected or impaired by reason of the adjudication in bankruptcy of any person or entity obligated under the Lease, the filing of a petition for any relief under the Bankruptcy Act, of Guarantor 4. Guarantor shall not be excused from any liability hereunder based on a defense, which the Tenant could not make or invoke and Guarantor hereby expressly waives any defense at law or in equity which is not or would not be available to the Tenant, it being the intent hereof that the liability of Guarantor hereunder is primary and unconditional. The parties confirm their general intent that the obligations of the Guarantor under this Guaranty and the obligations of Tenant under the Lease will be co-extensive as if the Guarantor were the Tenant under the Lease, but only to the extent the Tenant's performance obligations under the Lease are held to be limited or relieved due to the Landlord's non-performance under the Lease. Accordingly, the parties specifically agree that the co-extensive nature of Guarantor's obligations hereunder with Tenant's obligations under the Lease (i) will not apply to afford Guarantor the benefit of any technical defenses which may otherwise be available to excuse Tenant's performance under the Lease but which are unrelated either to Landlord's performance or non-performance under the Lease, or interpretations of the scope or application of certain provisions of the Lease themselves, and/or (ii) will not be construed to modify any of the express waivers made by Guarantor hereinbelow, such as waivers of notices of default and the like. 5. It is expressly understood and agreed that this is a continuing guaranty, and that the obligations of Guarantor hereunder are and shall be absolute under any and all circumstances, without regard to the validity, regularity and enforceability of the Lease or any other instruments executed in connection therewith. Guarantor hereby acknowledges that it has received and reviewed a true copy of the Lease and all such other instruments (if any). In the event it shall be asserted that Tenant's obligations are void or voidable due to illegal or unauthorized acts by Tenant in the F-2

execution of the Lease, the Guarantor shall nevertheless be liable hereunder to the same extent as the Guarantor would have been if the obligations of the Tenant had been enforceable against the Tenant. 6. Guarantor hereby waives notice of the acceptance hereof, presentment, demand for payment, protest, notice of protest and any and all notices of non-payment, non-performance, or non- observance, or other proof, or notice of demand. 7. Guarantor agrees that Landlord may, without notice to Guarantor or Tenant sell, assign or transfer all or any portion of Landlord's interest in the Lease, the Premises, the Building and/or the Project, and, in that event, each and every subsequent assignee, transferee or holder of all or any part of such interest shall have the right to enforce this Guaranty by suit or other remedy as if such assignee, transferee or holder were herein by name specifically given said rights, powers and benefits. 8. Guarantor agrees that in the event this Guaranty is placed in the hands of an attorney for enforcement, Guarantor will reimburse Landlord for all expenses incurred in connection therewith, including, but not limited to, reasonable attorneys' fees. 9. A. This Guaranty shall continue to be fully applicable following any assignment, sublease, exercise of any Expansion Option by Tenant or exercise of any Renewal Option (as each such term is defined in the Lease), and this Guaranty shall remain in full force and effect as to any renewal or extension, and as to any assigns of Tenant's interest under the Lease, and despite any subletting of all or any portion of the Premises, and as to any expansion of the Premises pursuant to the Expansion Options provided for in the Lease. B. This Guaranty shall remain in effect as to any amendment or modification of the Lease whether or not Guarantor had prior or subsequent notice of such modification or amendment and/or had consented thereto, and irrespective of whether such modification or amendment of the Lease has the intent or effect of increasing or extending the Tenant's obligation to the Landlord under the Lease. 10. This Guaranty shall be binding upon the successors and assigns of Guarantor, and shall inure to the benefit of and may be enforced by the Landlord and its successors and assigns. II. This Guaranty shall remain in full force and effect regardless of whether or not the relationship of Guarantor and Tenant, as described in the Recitals to this Guaranty, continues. 12. Guarantor hereby represents and warrants that the officer signing this Guaranty on its behalf has the full authority, and has been fully authorized, to execute and deliver this Guaranty and to bind Guarantor to the terms hereof. 13. This Guaranty shall be governed, construed and interpreted as to validity and enforcement and in all other respects in accordance with the laws of the State within which the Premises are located (without resort to choice oflaw principles) and cannot be modified, amended or terminated orally. Guarantors hereby acknowledge that the Lease and this Guaranty are performable in the County and State in which the Premises are located. Guarantor hereby irrevocably consents to F-3

the jurisdiction and proper venue of any court oflaw located in Cranberry Township or in Butler County, Pennsylvania, the county within which the Premises are located, as a proper forum for Landlord to bring a legal action to enforce this Guaranty and Guarantors obligations hereunder. 14. Guarantor hereby knowingly, voluntarily and irrevocably waives its right to demand a jury trial of any legal action to enforce this Guaranty or any of its obligations hereunder. 15. The payment by Guarantor of any amounts pursuant to this Guaranty shall not in any way entitle Guarantor to any right, title or interest (whether by subrogation or otherwise) of the Tenant under the Lease or to any security being held for any payment or obligation guaranteed hereby. 16. The Landlord and Guarantor intend and believe that each provision of this Guaranty comports with applicable law. However, if any provision of this Guaranty is found by a court to be invalid for any reason, the parties intend that the remainder of this Guaranty shall continue in full force and effect and the invalid provision shall be construed as if it were not contained herein. BY EXECUTING THIS GUARANTY, GUARANTOR HEREBY ACKNOWLEDGES THAT IT HAS REVIEWED, OR HAS HAD AN ADEQUATE OPPORTUNITY TO REVIEW, THIS GUARANTY AND THE LEASE REFERRED TO HEREIN WITH LEGAL COUNSEL, AND THAT IT IS ENTERING INTO THE OBLIGATIONS SET FORTH HEREIN KNOWINGLY AND VOLUNTARILY.

The parties agree that the parties shall generally conform to the provisions of Exhibit C with respect to the design and construction of physical improvements to the Additional Expansion Space, as if fully restated in this Section 52.3 (and subject to any specific modifications as to timing or other points of detail expressly set forth in this Section 52.3). 52.3.4 Promptly after Tenant's exercise of the Additional Expansion Option, Landlord shall prepare and Landlord and Tenant shall execute an amendment to this Lease confirming such exercise and incorporating the applicable terms of this Section 52. These provisions shall be self-operative, and such amendment shall merely confirm in a separate written instrument the terms and provisions set forth herein. 52.3.5 Tenant acknowledges and agrees that the Additional Expansion Option is not exclusive to Tenant, and unless and until Tenant has exercised the Additional Expansion Option, Landlord shall have the right (subject only to Tenant's Right of First Refusal, as defined in Section 52.4 below, for the period that such Right of First Refusal is in effect) to lease the Additional Expansion Space to any person or entity, free from the effect of the Additional Expansion Option, on such terms as Landlord determines in its sole and absolute discretion." -10- BOI 15687368.6/32203-000154

Notwithstanding the foregoing Tenant's right to offset against payments of Base Rent and additional rent payable by Tenant hereunder shall be limited to amounts reasonably expended by Tenant in performing maintenance and repairs which were not caused by the negligence ot the -+ willfully malicious act of Tenant or Tenant's Agents." 12. Article 50 of the Lease, as amended by Paragraph 11 of the First Amendment and Paragraph 10 of the Second Amendment, shall be deleted in its entirety and in lieu thereof shall be inserted the following: "50. RENEWAL OPTION A.) Renewal Option. Tenant is hereby granted one (1) option ("Renewal Option") to renew this Lease for a period of five (5) years ("Renewal Term"). Tenant may exercise the Renewal Option upon written notice ("Renewal Notice") given to Landlord no earlier than 365 days and no later than 270 days before the expiration of the Extended Term ("Notice Period"). If Tenant fails to give Landlord the Renewal Notice within the Notice Period, then Tenant shall be deemed to have elected not to exercise the Renewal Option and this Renewal Option shall be deemed to null and void; time being of the essence in with regard to delivery of the Renewal Notice. B.) Renewal Term. If the Renewal Notice is timely given, the Renewal Term will be on the same terms and conditions as those contained in the Lease except as follows: i. There shall be no further rights to renew after the exercise of the Renewal Option granted herein; ii. Any Tenant Improvement Allowances, TI Allowance, rental concessions, Landlord's Work or other such allowance improvements provided by Landlord to Tenant in the Lease shall not be applicable in the Renewal Term; iii. The Base Rent for the Renewal Term shall be 100% of the Fair Market Rental Value as determined by agreement between Landlord and Tenant or, if Landlord and Tenant are unable to agree, as set forth in sub- paragraph C immediately below. For purposes of this Article 50 the Fair Market Rental Value of the Premises shall be the amount that a willing, comparable, new (i.e., non-renewal), non-equity tenant would pay, and that a willing landlord of a comparable space, both in terms of size and age of the Premises and within a five (5) mile radius of Cranberry Woods 6

Office Park, would accept at arms' length. The Fair Market Rental Value for the Renewal Term may be less than the Base Rent paid by Tenant for the last year of the Extended Term. Appropriate consideration shall be given to (a) the annual rental rate per rentable square foot; (b) the definition of rentable square feet for purposes of comparing the rate; (c) location, quality and age of the Building; (d) the financial condition (e.g., creditworthiness) of Tenant; (e) escalation (including type, base year and stop) and abatement provisions reflecting free rent and lor no rent during the period of construction; (f) brokerage commissions, if any, (g) length of the lease term; (h) size and location (including floor level) of the Premises; (i) building standard work letter and/or tenant improvement allowance, if any; provided, however, the Fair Market Rental Value shall not include any tenant improvements or any alterations made by Tenant; (j) condition of space; (k) lease takeover/assumptions; (1) moving expenses and other concessions; (m) extent of services to be provided; (n) distinctions between "gross" and "net" leases; (0) base year figures or expense stops for escalation purposes for both operating costs and ad valorem/real estate taxes; (P) the time the particular rental rate under consideration becomes or is to become effective; (q) applicable caps, if any, on the amount of real estate taxes and assessments passed through to tenants; and (r) other generally applicable conditions of tenancy for the space in question. Tenant shall obtain the same rent and other benefits that Landlord would otherwise give to any comparable prospective tenant. iv. Base Year. Notwithstanding anything to the contrary contained in the Lease, commencing on January 1, 2017, the Operating Costs Base Year and Real Estate Tax Base Year for the Renewal Term shall be Calendar Year 2017. C.) AcceptancelRejection. If Landlord and Tenant are not able to agree on the Base Rent for the Renewal Term by a date which is two-hundred forty (240) days prior to the commencement date of the Renewal Term, then within thirty (30) days thereafter ("Appointment Period") each party shall appoint a real estate appraiser with at least ten (10) years full time commercial appraisal experience in valuing leasehold commercial office space in the vicinity of the Premises to determine the Base Rent based on the then Fair Market Rental Value for the Renewal Term. If either party fails to appoint a real estate appraiser within the Appointment Period the Base Rent of the duly appointed appraiser shall control. The two (2) appraisers appointed by the parties shall meet to set the then Base Rent for the Renewal Term. If they are unable to agree within twenty (20) days after expiration of the Appointment Period, they shall select a third appraiser, who shall be a person who meets the qualifications set forth in this paragraph and who has not previously acted in any capacity for either party. If the two appraisers are unable to agree upon a third appraiser, either of the parties may apply to the then presiding judge of the Common 7

Pleas Court of Butler County, Pennsylvania for the selection of the third (3rd) appraiser, who shall be a person who meets the qualifications set forth above. Landlord and Tenant shall each bear one-half (112) of the cost of appointing the third appraiser and of paying the third appraiser's fee. As soon as possible following selection or appointment of the third appraiser, the appraisers shall set the Base Rent for the Premises for the Renewal Term. If a majority of the appraisers is unable to set the Base Rent within twenty (20) days after appointment of the third appraiser, the three (3) appraisals shall be added together and their total divided by three (3); the resulting quotient shall be the Base Rent rate for the Premises for the Renewal Term. If the low appraisal is more than ten percent (10%) lower than the middle appraisal, the low appraisal shall be disregarded; if the high appraisal is more than ten percent (10%) higher than the middle appraisal, the high appraisal shall be disregarded. If only one appraisal is disregarded, the remaining two (2) appraisals shall be added together and their total divided by two (2), and the resulting quotient shall be the Base Rent rate for the Premises for the Renewal Term. If two of the appraisals shall be disregarded, the middle appraisal shall determine the Base Rent rate in the Renewal Term. Base Rent for the Renewal Term as so determined shall be effective as of the commencement date of the Renewal Term and shall be adjusted retroactively if determined after the commencement date ofthe Renewal Term. D.) Restrictions/Conditions. Tenant's Renewal Option shall be personal to McKesson Automation Inc. and shall terminate if (i) a Default shall exist at the time of exercise of the Renewal Option or the commencement date of the Renewal Term, or an event has occurred which with notice and the lapse of time shall be a Default if not cured at the time of exercise of the Renewal Option or the commencement date of the Renewal Term, (ii) the Lease or Tenant's right to possession of the Premises has been terminated, (iii) Tenant transfers any of its interest in this Lease or any portion of the Premises to any person or entity except a person or entity not requiring Landlord's consent as provided in Paragraph 9 of this Third Amendment. 13. Article 52 of the Lease, as amended by Paragraph 12 of the First, shall be deleted in its entirety and in lieu thereof shall be inserted the following: "52. EXPANSION 52.1 Non-Exclusive Expansion Option (a) During the Extended Term and the Renewal Term Tenant shall have the non-exclusive right ("Expansion Option"), but not the obligation, to add to the Premises any available office space in the Building that is then vacant and is not subject to a lease, letter of intent, term sheet or other 8

such agreement for use or occupancy by a third party ("Available Expansion Space"). Tenant acknowledges and agrees that this Expansion Option is not exclusive to Tenant and, unless and until Tenant exercise this Expansion Option, Landlord shall have the unencumbered right (subject only to Tenant's Right of First Refusal set forth in Section 52.2 below) to lease the Available Expansion Space to any person or entity on such terms as Landlord determines in its sole discretion. (b) Tenant may exercise the Expansion Option at any time during the Extended Term by written notice identifying the portion of the Available Expansion Space that Tenant desires to add to the Premises ("Office Expansion Space"). The configuration of the Office Expansion Space shall be subject to Landlord's reasonable approval based on the proportion of windows to rentable area, ingress, egress, access to common and core areas of the Building and the like with regard to both the Office Expansion Space and the remaining Available Expansion Space. Any Office Expansion Space with respect to which Tenant exercises its rights will be delivered by Landlord to Tenant in its "as-is" condition along with payment by Landlord to Tenant of an Office Expansion Allowance equal to the amount of $5.00 per square foot of rentable area of the Office Expansion Space desired by Tenant times a fraction, the numerator of which is the number of days remaining in the five (5) year Extended Term or the Renewal Term (if the Renewal Option has been duly exercised) after the applicable Office Expansion Space is added to the Premises and the denominator of which is the 1,825. Any Office Expansion Space will become part of the Premises on the date on which Landlord delivers such Office Expansion Space to Tenant in the condition required herein and the Premises will then be deemed to include any such Office Expansion Space. All of the provisions of this Lease will apply to any Office Expansion Space added to the Premises, provided, however, Landlord will not be obligated to grant any concessions or allowances with respect to any Office Expansion Space except as set forth in this Section 52.1. (c) The Base Rent rate for any Office Expansion Space will be the Base Rent rate in effect on the date on which the applicable Office Expansion Space becomes part of the Premises, subject to subsequent increases, if any, as provided in this Third Amendment. The Base Rent will be increased as of the day on which the Office Expansion Space becomes part of the Premises by an amount equal to the product of (i) the number of rentable square feet of the applicable Office Expansion Space multiplied by (ii) the Base Rent per rentable square foot of the Premises in effect on the day on which the Office Expansion Space becomes part of the Premises. Tenant's Share will be increased as of the day on which any Office Expansion Space becomes part of the Premises to a fraction whose numerator is the sum of the rentable square feet of the Premises and the new Office Expansion Space, and whose denominator is the rentable 9

square feet of the Building. The Base Rent and Tenant's Share will be increased in a similar manner whenever Office Expansion Space is added to the Premises. (d) Tenant's rights granted in this Paragraph are personal to McKesson Automation, Inc. and shall terminate if (i) a Default shall exist at the time of exercise of the Expansion Option, or an event has occurred which with notice and the lapse of time shall be a Default if not cured at the time of exercise of the Expansion Option, (ii) the Lease or Tenant's right to possession of the Premises has been terminated, (iii) Tenant transfers any of its interest in this Lease or any portion of the Premises to any person or entity except a person or entity not requiring Landlord's consent as provided in Paragraph 9 of this Third Amendment, or (iv) less than two full years remain in the Lease Term (unless during the Extended Term Tenant exercises the Renewal Option. 52.2 Right of First Refusal (a) Refusal Space/Offer. Reference is made to any available office space in the Building that is then vacant and is not subject to a lease, letter of intent, term sheet or other such agreement for use or occupancy by a third party ("Available Refusal Space"). If during the Extended Term or the Renewal Term, Landlord receives a bona fide offer from a third party ("Third Party Offer") to lease all or any portion of the Available Refusal Space ("Refusal Space") and Landlord is willing to accept the terms of such Third Party Offer, Landlord shall first offer ("Offer Notice") to lease to Tenant the Refusal Space on the same terms and conditions as the Third Party Offer; such Offer Notice shall be in writing, specify the rent to be paid for the Refusal Space, contain the other basic terms and conditions of the Third Party Offer and the date on which the Refusal Space shall be included in the Premises. Tenant shall notify Landlord in writing whether Tenant elects to lease all of the Refusal Space on the same terms and conditions as the Third Party Offer set forth in the Offer Notice within fifteen (15) business days after Landlord delivers to Tenant the Offer Notice, time being of the essence. (b) Acceptance. If Tenant timely elects to lease the Refusal Space within such fifteen (15) business day period, then Landlord and Tenant shall execute an amendment to the Lease, effective as of the date the Refusal Space is to be included in the Premises, on the same terms as the Lease except (i) the Base Rent rate for the Refusal Space shall be the amount specified in the Offer Notice, (ii) the lease term for the Refusal Space shall be that specified in the Offer Notice and, if the lease term in the Offer Notice extends beyond the expiration of the Term of this Lease, Tenant shall be permitted to extend the Term of this Lease to be coterminous with the lease term for the Refusal Space, (iii) the Refusal Space shall be 10

delivered to Tenant and Tenant shall take same in "as-is" condition, and Landlord shall not be required to construct any tenant improvements in the Refusal Space or provide to Tenant any allowances other than those contained in the Offer Notice, if any, and (iv) any other terms set forth in the Lease which are inconsistent with the terms of the Offer Notice shall be modified accordingly with respect to the Refusal Space. Notwithstanding the foregoing, if the Offer Notice includes space in excess of that desired by Tenant, Tenant must exercise its right hereunder, if at all, as to all of the space contained in the Offer Notice. If the Offer Notice is for less than all the Available Refusal Space, then the Right of First Refusal shall continue for the remainder of any Available Refusal Space. (c) Rejection. If Tenant fails or is unable to timely exercise its right hereunder, then such right shall lapse, time being of the essence with respect to the exercise thereof, and Landlord may lease the portion of the Refusal Space described in the Offer Notice to the third party on the terms contained in the Offer Notice or such terms as Landlord may elect. (d) On-Going Right. If an Offer Notice that was rejected is for less than all of the Refusal Space, then Landlord shall only be obligated to offer such remaining portion of the Refusal Space to Tenant if a Third Party Offer is subsequently received for such remaining portion. (e) Exclusion. For purposes hereof, if an Offer Notice is delivered for less than all of the Available Refusal Space, but such notice provides for an expansion, right of first refusal, or other preferential right to lease some of the remaining portion of the Available Refusal Space, then such remaining portion of the Available Refusal Space shall thereafter be excluded from the grant of the Right of First Refusal contained herein. (f) Restrictions. This Right of First Refusal is personal to McKesson Automation Inc. and shall terminate if (i) a Default shall exist at the time of Tenants' election to lease the Refusal Space, or an event has occurred which with notice and the lapse of time shall be a Default if not cured at the time of Tenant's election to lease the Refusal Space, (ii) the Lease or Tenant's right to possession of the Premises has been terminated, (iii) Tenant transfers any of its interest in this Lease or any portion of the Premises to any person or entity except a person or entity not requiring Landlord's consent as provided in Paragraph 9 of this Third Amendment, or (iv) less than two full years remain in the Lease Term (unless during the Extended Term Tenant exercises the Renewal Option." 14. The second sentence of Article 28 of the Original Lease is hereby deleted in its entirety, and in lieu thereof is inserted the following: 11

"During any such holdover tenancy, unless Landlord has otherwise agreed in writing, Tenant agrees to pay to Landlord an occupancy charge equal to (A) 125% of the stated monthly Base Rent for the last full month of the Extended Term or Renewal Term (as applicable) then ending, calculated on a per diem basis, for each day of the first (1st) month of such holdover, (B) 150% of the stated monthly Base Rent for the last full month of the Extended Term or Renewal Term (as applicable) then ending, calculated on a per diem basis, for each day after the first month of such holdover, and (C) one hundred percent (100%) of the additional rent which would have been payable by Tenant for the period of such holdover, calculated on a per diem basis using the additional rent which had otherwise been payable by Tenant for the last full month of the Extended Term or the Renewal Term (as applicable) then ending." 15. As a condition precedent to execution of this Third Amendment by Tenant Landlord, at its sole cost and expense, shall cause any existing mortgagee or trust deed beneficiary holding a lien encumbering the Building to enter into the subordination, non-disturbance and attornment agreement in the form attached hereto as Exhibit B. 16.

location, quality and age of the Building; (d) the financial condition (e.g., creditworthiness) of Tenant; (e) escalation (including type, base year and stop) and abatement provisions reflecting free rent and lor no rent during the period of construction; (f) brokerage commissions, if any, (g) length of the lease term; (h) size and location (including floor level) of the Premises; (i) building standard work letter and/or tenant improvement allowance, if any; provided, however, the Fair Market Rental Value shall not include any tenant improvements or any alterations made by Tenant; (j) condition of space; (k) lease takeover/assumptions; (1) moving expenses and other concessions; (m) extent of services to be provided; (n) distinctions between "gross" and "net" leases; (0) base year figures or expense stops for escalation purposes :Orboth operating costs and ad valorem/real estate taxes; (P) the time the particular rental rate under consideration becomes or is to become effective; (q) applicable caps, if any, on the amount ofreal estate taxes and assessments passed through to tenants; and (r) other generally applicable conditions of tenancy for the space in question. Tenant shall obtain the same rent and other benefits that Landlord would otherwise give to any comparable prospective tenant. iv. Base Year.

If Landlord and Tenant are not able to agree on the Base Rent for the Renewal Term by a date which is two-hundred forty (240) days prior to the commencement date of the Renewal Term, then within thirty (30) days thereafter ("Appointment Period") each party shall appoint a real estate appraiser with at least ten (10) years full time commercial appraisal experience in valuing leasehold commercial office space in the vicinity of the Premises to determine the Base Rent based on the then Fair Market Rental Value for the Renewal Term. If either party fails to appoint a real estate appraiser within the Appointment Period the Base Rent of the duly appointed appraiser shall control. The two (2) appraisers appointed by the parties shall meet to set the then Base Rent for the Renewal Term. If they are unable to agree within twenty (20) days after expiration of the Appointment Period, they shall select a third appraiser, who shall be a person who meets the qualifications set forth in this paragraph and who has not previously acted in any capacity for either party. If the two appraisers are unable to agree upon a third appraiser, either of the parties may apply to the then presiding judge of the Common Pleas Court of Butler County, Pennsylvania for the selection of the third (3rd) appraiser, who shall be a person who meets the qualifications set forth above. Landlord and Tenant shall each bear one-half (112) of the cost of appointing the third appraiser and of paying the third appraiser's fee. As soon as possible following selection or appointment of the third 5

appraiser, the appraisers shall set the Base Rent for the Premises for the Renewal Term. If a majority of the appraisers is unable to set the Base Rent within twenty (20) days after appointment of the third appraiser, the three (3) appraisals shall be added together and their total divided by three (3); the resulting quotient shall be the Base Rent rate for the Premises for the Renewal Term. If the low appraisal is more than ten percent (10%) lower than the middle appraisal, the low appraisal shall be disregarded; if the high appraisal is more than ten percent (l 0%) higher than the middle appraisal, the high appraisal shall be disregarded. If only one appraisal is disregarded, the remaining two (2) appraisals shall be added together and their total divided by two (2), and the resulting quotient shall be the Base Rent rate for the Premises for the Renewal Term. If two of the appraisals shall be disregarded, the middle appraisal shall determine the Base Rent rate in the Renewal Term. Base Rent for the Renewal Term as so determined shall be effective as of the commencement date of the Renewal Term and shall be adjusted retroactively if determined after the commencement date of the Renewal Term. D.) Restrictions/Conditions. Tenant's Renewal Option shall be personal to McKesson Automation Inc. and shall terminate if (i) a Default shall exist at the time of exercise of the Renewal Option or the commencement date of the Renewal Term, or an event has occurred which with notice and the lapse of time shall be a Default if not cured at the time of exercise of the Renewal Option or the commencement date of the Renewal Term, (ii) the Lease or Tenant's right to possession of the Premises has been terminated, (iii) Tenant transfers any of its interest in this Lease or any portion of the Premises except to an entity not requiring Landlord's consent as provided in the Lease." 10. Expansion. Article 52 of the Lease, as amended by Paragraph 12 of the First Amendment and Paragraph 13 of the Third Amendment, shall be deleted in its entirety and in lieu thereof shall be inserted the following: "52. EXPANSION 52.1 Non-Exclusive Expansion Option (a) During the Lease Term Tenant shall have the non-exclusive right ("Expansion Option"), but not the obligation, to add to the Premises any available office space in the Building that is then vacant and is not subject to a lease, letter of intent, term sheet or other such agreement for use or occupancy by a third party ("Available Expansion Space"). Tenant acknowledges and agrees that this Expansion Option is not exclusive to Tenant and, unless and until Tenant exercise this Expansion Option, Landlord shall have the unencumbered right (subject only to Tenant's Right of First Refusal set forth in Section 52.2 below) to lease the 6

Available Expansion Space to any person or entity on such terms as Landlord determines in its sole discretion. (b) Tenant may exercise the Expansion Option at any time during the Lease Term by written notice identifying the portion of the Available Expansion Space that Tenant desires to add to the Premises ("Office Expansion Space"). The configuration of the Office Expansion Space shall be subject to Landlord's reasonable approval based on the proportion of windows to rentable area, ingress, egress, access to common and core areas of the Building and the like with regard to both the Office Expansion Space and the remaining Available Expansion Space. Any Office Expansion Space with respect to which Tenant exercises its rights will be delivered by Landlord to Tenant in its "as-is" condition along with payment by Landlord to Tenant of an Office Expansion Allowance equal to the amount of$5.00 per square foot of rentable area ofthe Office Expansion Space desired by Tenant times a fraction, the numerator of which is the number of clays remaining in the Lease Term after the applicable Office Expansion Space is added to the Premises and the denominator of which is the 2,920. Any Office Expansion Space will become part of the Premises on the date on which Landlord delivers such Office Expansion Space to Tenant in the condition required herein and the Premises will then be deemed to include any such Office Expansion Space. All of the provisions of this Lease will apply to any Office Expansion Space added to the Premises, provided, however, Landlord will not be obligated to grant any concessions or allowances with respect to any Office Expansion Space except as set forth in this Section 52.1. (c) The Base Rent rate for any Office Expansion Space will be the Base Rent rate in effect on the date on which the applicable Office Expansion Space becomes part of the Premises, subject to subsequent increases in Base Rent during the Lease Term. The Base Rent will be increased as of the day on which the Office Expansion Space becomes part of the Premises by an amount equal to the product of (i) the number of rentable square feet of the applicable Office Expansion Space multiplied by (ii) the Base Rent per rentable square foot of the Premises in effect on the day on which the Office Expansion Space becomes part of the Premises. Tenant's Share will be increased as of the day on which any Office Expansion Space becom;:s part of the Premises to a fraction whose numerator is the sum of the rentable square feet of the Premises and the new Office Expansion Space, and whose denominator is the rentable square feet of the Building. The Base Rent and Tenant's Share will be increased in a similar manner whenever Office Expansion Space is added to the Premises. (d) Tenant's rights grant.ed in this Paragraph are personal to McKesson Automation, Inc. and shall terminate if (i) a Default shall exist at the time 7

Reference is made to any available office space in the Building that is then vacant and is not subject to a lease, letter of intent, term sheet or other such agreement for use or occupancy by a third party ("Available Refusal Space"). If during the Lease Term, Landlord receives a bona fide offer from a third party ("Third Party Offer") to lease all or any portion of the Available Refusal Space ("Refusal Space") and Landlord is willing to accept the terms of such Third Party Offer, Landlord shall first offer ("Offer Notice") to lease to Tenant the Refusal Space on the same terms and conditions as the Third Party Offer; such Offer Notice shall be in writing, specify the rent to be paid for the Refusal Space, contain the other basic terms and conditions of the Third Party Offer and the date on which the Refusal Space shall be included in the Premises. Tenant shall notify Landlord in writing whether Tenant elects to lease all of the Refusal Space on the same terms and conditions as the Third Party Offer set forth in the Offer Notice within fifteen (15) business days after Landlord delivers to Tenant the Offer Notice, time being of the essence. (b) Acceptance. If Tenant timely elects to lease the Refusal Space within such fifteen (15) business day period, then Landlord and Tenant shall execute an amendment to the Lease, effective as of the date the Refusal Space is to be included in the Premises, on the same terms as the Lease except (i) the Base Rem rate for the Refusal Space shall be the amount specified in the Offer Notice, (ii) the lease term for the Refusal Space shall be that specified in the Offer Notice and, if the lease term in the Offer Notice extends beyond the expiration of the Lease Term of this Lease, Tenant shall be permitted to extend the Lease Term of this Lease to be coterminous with the lease term for the Refusal Space, (iii) the Refusal Space shall be delivered to Tenant and Tenant shall take same in "as-is" condition, and Landlord shall not be required to construct any tenant improvements in the Refusal Space or provide to Tenant any allowances other than those contained in the Offer Notice, if any, and (iv) any other terms set forth in the Lease which are inconsistent with the terms of the Offer Notice shall be modified accordingly with respect to the Refusal Space. Notwithstanding the foregoing, if the Offer Notice includes space in excess of that desired by Tenant, Tenant must exercise its right 8

hereunder, if at all, as to all of the space contained in the Offer Notice. If the Offer Notice is for less than all the Available Refusal Space, then the Right of First Refusal shall continue for the remainder of any Available Refusal Space. (c) Rejection. If Tenant fails or is unable to timely exercise its right hereunder, then such right shall lapse, time being of the essence with respect to the exercise thereof, and Landlord may lease the portion of the Refusal Space described in the Offer Notice to the third party on the terms contained in the Offer Notice or such terms as Landlord may elect. (d) On-Going Right. If an Offer Notice that was rejected is for less than all of the Refusal Space, then Landlord shall only be obligated to offer such remaining portion of the Refusal Space to Tenant if a Third Party Offer is subsequently received for such remaining portion. (e) Exclusion. For purposes hereof, if an Offer Notice is delivered for less than all of the Available Refusal Space, but such notice provides for an expansion, right of first: efusal, or other preferential right to lease some of the remaining portion of the Available Refusal Space, then such remaining portion of the Available Refusal Space shall thereafter be excluded from the grant of the Right of First Refusal contained herein. (f) Restrictions. This Right of First Refusal is personal to McKesson Automation Inc. and shall terminate if (i) a Default shall exist at the time of Tenants' election to lease the Refusal Space, or an event has occurred which with notice and the lapse of time shall be a Default if not cured at the time of Tenant's election to lease the Refusal Space, (ii) the Lease or Tenant's right to possession of the Premises has been terminated, (iii) Tenant transfers any of its interest in this Lease or any portion of the Premises except to an entity not requiring Landlord's consent as provided in the Lease, or (iv) less than two full years remain in the Lease Term." 11.
