WORK AGREEMENT FOR EXPANSION PREMISES 1

1.1                               Substantial Completion

(A)                               Plans and Construction Process.

(1)                                 Landlord’s Work. Landlord shall perform the work shown on the plans (the “Plans”) listed on Exhibit C-2 attached to this First Amendment (“Landlord’s Expansion Premises 1 Work”); provided, however, that Landlord shall have no responsibility for the installation or connection of Tenant’s computer, telephone, other communication equipment, systems or wiring. Any items of work requested by Tenant and not shown on the Plans shall be deemed to be Change Proposal(s) (as defined below) and shall be subject to the terms and provisions of subsection (2) below.

(2)                                 Change Orders. Tenant shall have the right, in accordance herewith, to submit for Landlord’s approval change proposals with respect to items of work not shown on the Plans (each, a “Change Proposal”). Landlord agrees to respond to any such Change Proposal within such time as is reasonably necessary (taking into consideration the information contained in such Change Proposal) after the submission thereof by Tenant, advising Tenant of any anticipated increase in costs, which costs shall include a construction management fee equal to four percent (4%) of the Change Proposal (“Change Order Costs”) associated with such Change Proposal, as well as an estimate of any delay which would likely result in the completion of the Landlord’s Expansion Premises 1 Work if a Change Proposal is made pursuant thereto (“Landlord’s Change Order Response”). Tenant shall have the right to then approve or withdraw such Change Proposal within five (5) days after receipt of Landlord’s Change Order Response. If Tenant fails to respond to Landlord’s Change Order Response within such five (5) day period, such Change Proposal shall be deemed withdrawn. If Tenant approves Landlord’s Change Order Response, then such Change Proposal shall be deemed a “Change Order” hereunder and if the Change Order is made, then the Change Order Costs associated with the Change Order shall be deemed additions to the Tenant Plan Excess Costs and shall be paid in the same manner as Tenant Plan Excess Costs are paid as set forth in Section 1.4 of this Work Agreement.

(3)                                 Tenant Response to Requests for Information and Approvals. Except to the extent that another time period is expressly herein set forth, Tenant shall respond to any request from Landlord, Landlord’s architect, Landlord’s contractor and/or Landlord’s Construction Representative for approvals or information in connection with Landlord’s Expansion Premises 1 Work,

Exhibit C-1

FINAL

within three (3) business days of Tenant’s receipt of such request. In addition, Tenant shall, within two (2) business days after receipt thereof from Landlord, execute and deliver to Landlord any affidavits and documentation required in order to obtain all permits and approvals necessary for Landlord to commence and complete Landlord’s Expansion Premises 1 Work on a timely basis (“Permit Documentation”).

(4)                                 Time of the Essence. Time is of the essence in connection with Tenant’s obligations under this Section 1.1.

(B)                               Substantial Completion; Tenant Delay.

(1)                                 Landlord’s Obligations. Subject to delays due to Tenant Delays (as hereinafter defined) and delays due to Force Majeure, as defined in Section 6.1 of the Lease, Landlord shall use reasonable speed and diligence to have the Landlord’s Expansion Premises 1 Work substantially completed on or before January 1, 2016 (the “Estimated Expansion Premises 1 Commencement Date”), but Tenant shall have no claim against Landlord for failure so to complete construction of Landlord’s Expansion Premises 1 Work in the Expansion Premises 1 by the Estimated Expansion Premises 1 Commencement Date.

(2)                                 Definition of Substantial Completion. The Expansion Premises 1 shall be treated as having been substantially completed for the purposes of Section 2.1(A) of the First Amendment on the later of:

(a)                                 The date on which Landlord’s Expansion Premises 1 Work, together with common facilities for access and services to the Expansion Premises 1, has been completed (or would have been completed except for Tenant Delay) except for items of work and adjustment of equipment and fixtures which can be completed after occupancy has been taken without causing substantial interference with Tenant’s use of the Expansion Premises 1 (i.e. so-called “punch list” items), or

(b)                                 The date when permission has been obtained from the applicable governmental authority, to the extent required by law, for occupancy by Tenant of the Expansion Premises 1 for the Permitted Use, unless the failure to obtain such permission is due to a Tenant Delay.

In the event of any dispute as to the date on which Landlord’s Expansion Premises 1 Work has been completed, the reasonable determination of

2

FINAL

Landlord’s architect as to such date shall be deemed conclusive and binding on both Landlord and Tenant.

(3)                                 Incomplete Work. Landlord shall complete as soon as conditions practically permit any incomplete items of Landlord’s Expansion Premises 1 Work, and Tenant shall cooperate with Landlord in providing access as may be required to complete such work in a normal manner.

(4)                                 Early Access by Tenant. Landlord shall permit Tenant access for installing Tenant’s furniture and tel/data systems in portions of the Expansion Premises 1 prior to substantial completion when it can be done without material interference with remaining work or with the maintenance of harmonious labor relations. Any such access by Tenant shall be upon all of the terms and conditions of the Lease (other than the payment of Annual Fixed Rent) and shall be at Tenant’s sole risk, and Landlord shall not be responsible for any injury to persons or damage to property resulting from such early access by Tenant.

(5)                                 Prohibition on Access by Tenant Prior to Actual Substantial Completion. If, prior to the date that the Expansion Premises 1 are in fact actually substantially complete, the Expansion Premises 1 are deemed to be substantially complete as a result of a “Tenant Delay” (as defined below) (i.e. and the Expansion Premises 1 Commencement Date has therefor occurred), Tenant shall not (except with Landlord’s consent) be entitled to take possession of the Expansion Premises 1 for the Permitted Use until the Expansion Premises 1 are in fact actually substantially complete.

for the work in or to the Expansion Premises 1 and require additional time for receipt or installation; provided Landlord notified Tenant of the same constituting a long-lead item and Tenant did not substitute another non long-lead item within three (3) days of Landlord’s notice (Landlord acknowledges that the plan attached as part of Exhibit B-2 does not include any long-lead items);

(d)                                 Any delay due to changes, alterations or additions required or made by Tenant with respect to items not shown on the Plans including, without limitation, Change Orders; or

(e)                                  Any other delays caused by Tenant, Tenant’s contractors, architects, engineers, or anyone else engaged by Tenant in connection with the preparation of the Expansion Premises 1 for Tenant’s occupancy, including, without limitation, utility companies and other entities furnishing communications, data processing or other service, equipment, or furniture.

(2)                                 Tenant Obligations with Respect to Tenant Delays.

(a)                                 Tenant covenants that no Tenant Delay shall delay the occurrence of the Expansion Premises 1 Commencement Date or the obligation to pay Annual Fixed Rent or Additional Rent with respect to Expansion Premises 1, regardless of the reason for such Tenant Delay or whether or not it is within the control of Tenant or any such employee. Landlord’s Expansion Premises 1 Work shall be deemed substantially completed as of the date when Landlord’s Expansion Premises 1 Work would have been substantially completed but for any Tenant Delays, as determined by Landlord in the exercise of its good faith business judgment.

(b)                                 Tenant shall reimburse Landlord the amount, if any, by which the cost of Landlord’s Expansion Premises 1 Work is increased as the result of any Tenant Delay.

(c)                                  Any amounts due from Tenant to Landlord under this Section 1.1(C)(2) shall be due and payable within thirty (30) days of billing therefor (except that amounts due in connection with Change Orders shall be paid as provided in Section 1.4), and shall be considered to be Additional Rent. Nothing contained in this Section 1.1(C)(2) shall limit or qualify or prejudice any other covenants, agreements, terms, provisions and conditions contained

in the Lease.

1.2                               Quality and Performance of Work

All construction work required or permitted by the Lease shall be done in a good and workmanlike manner and in compliance with Legal Requirements and all Insurance Requirements. All of Tenant’s work shall be coordinated with any work being performed by or for Landlord and in such manner as to maintain harmonious labor relations. Each party may inspect the work of the other at reasonable times and shall promptly give notice of observed defects. Each party authorizes the other to rely in connection with design and construction upon approval and other actions on the party’s behalf by any Construction Representative of the party named in Section 1.1 of the Lease or any person hereafter designated in substitution or addition by notice to the party relying. Except to the extent to which Tenant shall have given Landlord notice of respects in which Landlord has not performed Landlord’s construction obligations under this Work Agreement not later than the end of the sixth (6th) full calendar month next beginning after the Expansion Premises 1 Commencement Date, Tenant shall be deemed conclusively to have approved Landlord’s construction and shall have no claim that Landlord has failed to perform any of Landlord’s obligations under this Work Agreement. Landlord agrees to correct or repair at its expense items which are then incomplete or do not conform to the work contemplated under the Plans and as to which, in either case, Tenant shall have given notice to Landlord, as aforesaid.

1.3                               Special Allowance

Landlord shall provide to Tenant a special allowance equal to the product of (i) $46.00, and (ii) the Rentable Floor Area of the Expansion Premises 1 (the “Tenant Allowance”). The Tenant Allowance shall be used and applied by Landlord solely on account of the cost of the Landlord’s Expansion Premises 1 Work. Any costs of performing the Landlord’s Expansion Premises 1 Work in excess of the Tenant Allowance shall be Tenant’s responsibility and shall be deemed Tenant Plan Excess Costs to be paid in accordance with Section 1.4 below. In no event shall Landlord’s obligations to pay for the Landlord’s Expansion Premises 1 Work exceed the total Tenant Allowance. Notwithstanding the foregoing, Landlord shall be under no obligation to apply any portion of the Tenant Allowance for any purposes other than as provided in this Section 1.3. In addition, in the event that (i) Tenant is in default under the Lease, or (ii) there are any liens which are not bonded to the reasonable satisfaction of Landlord against Tenant’s interest in the Lease or against the Building or the Site arising out of any work performed by Tenant or any litigation in which Tenant is a party, then, from and after the date of such event (“Event”), Landlord shall have no further obligation to fund any portion of the Tenant Allowance and Tenant shall be obligated to pay, as Additional Rent, all costs of the Landlord’s Expansion Premises 1 Work in excess of that portion of the Tenant Allowance funded by Landlord through the date of the Event. Further, the Tenant Allowance shall only be applied towards the cost of leasehold improvements and in no event shall Landlord be required to make application of any portion of the Tenant

5

FINAL

Allowance towards Tenant’s personal property, trade fixtures or moving expenses or on account of any supervisory fees, overhead, management fees or other payments to Tenant, or any partner or affiliate of Tenant. In the event that the costs of the Landlord’s Expansion Premises 1 Work are less than the Tenant Allowance, Tenant shall not be entitled to any payment or credit nor shall there be any application of the same toward Annual Fixed Rent or Additional Rent owed by Tenant under the Lease.

1.4                               Tenant Plan Excess Costs

Notwithstanding anything contained in this Work Agreement to the contrary, it is understood and agreed that Tenant shall be fully responsible for the (i) costs of Landlord’s Expansion Premises 1 Work in excess of the Tenant Allowance, and (ii) costs of any items of work not shown on Exhibit C-2 attached to the First Amendment and the costs of any items of work shown as a “Tenant Cost” on Exhibit C-2 (by virtue of an “X” being noted in the Tenant Cost column) (the “Tenant Plan Excess Costs”). To the extent, if any, that there are Tenant Plan Excess Costs, Tenant shall pay Landlord, as Additional Rent, fifty percent (50%) of the Tenant Plan Excess Costs prior to the commencement of the Landlord’s Expansion Premises 1 Work, with the balance of the Tenant Plan Excess Costs due upon substantial completion of the Landlord’s Expansion Premises 1 Work; provided, however, that (x) if the Tenant Plan Excess Costs exceed $10,000.00 (the “Maximum Amount”), then Tenant shall pay to Landlord, as Additional Rent,  all Tenant Plan Excess Costs in excess of the Maximum Amount prior to the commencement of the Landlord’s Expansion Premises 1 Work and (y) if the Tenant Plan Excess Costs exceed the Maximum Amount as a result of a Change Order, then Tenant shall pay to Landlord, as Additional Rent, at the time Tenant approves such Change Order in accordance with Section 1.1(A)(2), all such Tenant Plan Excess Costs in excess of the Maximum Amount.

completed as of the date when Landlord’s Expansion Premises 2 Work would have been substantially completed but for any Tenant Delays, as determined by Landlord in the exercise of its good faith business judgment.

(1)                                 Landlord’s Obligations. Subject to Tenant Delays and delays due to Force Majeure (as defined in Section 6.1 of the Lease), Landlord shall use reasonable speed and diligence to have Landlord’s Expansion Premises 2 Work substantially completed on or before November 1, 2016 (the “Estimated Expansion Premises 2 Commencement Date”), but Tenant shall have no claim against Landlord for failure so to complete construction of Landlord’s Expansion Premises 2 Work in the Expansion Premises 2 by the Estimated Expansion Premises 2 Commencement Date.

FINAL

(b)                                 The date when permission has been obtained from the applicable governmental authority, to the extent required by law, for occupancy by Tenant of the Expansion Premises 2 for the Permitted Use, unless the failure to obtain such permission is due to a Tenant Delay.

In the event of any dispute as to the date on which Landlord’s Expansion Premises 2 Work has been substantially completed, the reasonable determination of Landlord’s architect as to such date shall be deemed conclusive and binding on both Landlord and Tenant.

(3)                                 Incomplete Work. Landlord shall complete as soon as conditions practically permit any incomplete items of Landlord’s Expansion Premises 2 Work, and Tenant shall cooperate with Landlord in providing access as may be required to complete such work in a normal manner.

(4)                                 Early Access by Tenant. Landlord shall permit Tenant access for installing Tenant’s furniture and tel/data equipment in portions of the Expansion Premises 2 prior to substantial completion when it can be done without material interference with remaining work or with the maintenance of harmonious labor relations. Any such access by Tenant shall be at upon all of the terms and conditions of the Lease (other than the payment of Annual Fixed Rent) and shall be at Tenant’s sole risk, and Landlord shall not be responsible for any injury to persons or damage to property resulting from such early access by Tenant.

(5)                                 Prohibition on Access by Tenant Prior to Actual Substantial Completion. If, prior to the date that the Expansion Premises 2 are in fact actually substantially complete, the Expansion Premises 2 are deemed to be substantially complete as a result of a Tenant Delay (i.e. and the Commencement Date has therefor occurred), Tenant shall not (except with Landlord’s consent) be entitled to take possession of the Expansion Premises 2 for the Permitted Use until the Expansion Premises 2 are in fact actually substantially complete.

1.2                               Quality and Performance of Work

All construction work required or permitted by the Lease shall be done in a good and workmanlike manner and in compliance with Legal Requirements and all Insurance Requirements. All of Tenant’s work shall be coordinated with any work being performed by or for Landlord and in such manner as to maintain harmonious labor relations. Each party may inspect the work of the other at reasonable times and shall promptly give notice of observed defects. Each party authorizes the other to rely in connection with design and construction upon approval and other actions on the party’s behalf by any Construction Representative of the party named in Section 1.1 of the Lease or any person

hereafter designated in substitution or addition by notice to the party relying. Except to the extent to which Tenant shall have given Landlord notice of respects in which Landlord has not performed Landlord’s construction obligations under this Work Agreement not later than the end of the sixth (6th) full calendar month next beginning after the Expansion Premises 2 Commencement Date, Tenant shall be deemed conclusively to have approved Landlord’s construction and shall have no claim that Landlord has failed to perform any of Landlord’s obligations under this Work Agreement. Landlord agrees to correct or repair at its expense items which are then incomplete or do not conform to the work contemplated under the Plans and as to which, in either case, Tenant shall have given notice to Landlord, as aforesaid.

1.3                               Special Allowance

Landlord shall provide to Tenant a special allowance equal to the product of (i) $32.00, and (ii) the Rentable Floor Area of the Expansion Premises 2 (the “Tenant Allowance”). The Tenant Allowance shall be used and applied by Landlord solely on account of the cost of Landlord’s Expansion Premises 2 Work. In no event shall Landlord’s obligations to pay or reimburse Tenant for any of the costs of Landlord’s Expansion Premises 2 Work exceed the total Tenant Allowance. Notwithstanding the foregoing, Landlord shall be under no obligation to apply any portion of the Tenant Allowance for any purposes other than as provided in this Section 1.3. In addition, in the event that (i) Tenant is in default under the Lease or (ii) there are any liens which are not bonded to the reasonable satisfaction of Landlord against Tenant’s interest in the Lease or against the Building or the Site arising out of any work performed by Tenant or any litigation in which Tenant is a party, then, from and after the date of such event (“Event”), Landlord shall have no further obligation to fund any portion of the Tenant Allowance and Tenant shall be obligated to pay, as Additional Rent, all costs of Landlord’s Expansion Premises 2 Work in excess of that portion of the Tenant Allowance funded by Landlord through the date of the Event. Further, the Tenant Allowance shall only be applied towards the cost of leasehold improvements and in no event shall Landlord be required to make application of any portion of the Tenant Allowance towards Tenant’s personal property, trade fixtures or moving expenses or on account of any supervisory fees, overhead, management fees or other payments to Tenant, or any partner or affiliate of Tenant. In the event that the costs of Landlord’s Expansion Premises 2 Work are less than the Tenant Allowance, Tenant shall not be entitled to any payment or credit nor shall there be any application of the same toward Annual Fixed Rent or Additional Rent owed by Tenant under the Lease.

1.4                               Payment of Tenant Plan Excess Costs

To the extent, if any, that there are Tenant Plan Excess Costs, Tenant shall pay Landlord, as Additional Rent, fifty percent (50%) of the Tenant Plan Excess Costs prior to the commencement of the Landlord’s Expansion 2 Work, with the balance of the Tenant Plan Excess Costs due upon substantial completion of the Landlord’s Expansion 2 Work; provided, however, that (x) if the Tenant Plan Excess Costs exceed $10,000.00 (the

“Maximum Amount”), then Tenant shall pay to Landlord, as Additional Rent, all Tenant Plan Excess Costs in excess of the Maximum Amount prior to the commencement of the Landlord’s Expansion 2 Work and (y) if the Tenant Plan Excess Costs exceed the Maximum Amount as a result of a Change Order, then Tenant shall pay to Landlord, as Additional Rent, at the time Tenant approves such Change Order in accordance with Section 1.1(A)(4), all such Tenant Plan Excess Costs in excess of the Maximum Amount.
