WITNESSETH:

WHEREAS, Landlord and Tenant are party to that certain Lease, dated as of September 26, 1994 (the “Original Lease”), as amended by that certain Letter Agreement, dated as of July 30, 1997 (the “First Amendment”), as further amended by that certain Second Amendment to Lease, dated as of September 12, 2001 (the “Second Amendment”), as further amended by that certain Third Amendment to Lease, dated as of May 5, 2011 (the “Third Amendment”), as further amended by that certain Fourth Amendment to Lease, dated as of February 25, 2014 (the “Fourth Amendment”, and collectively with the Original Lease, the First Amendment, the Second Amendment, and the Third Amendment, the “Lease”, as may be further amended or modified from time to time), pursuant to which Landlord leases to Tenant certain premises consisting of approximately 45,700 rentable square feet with a common address of 25 Eastmans Road, Suite 100, Parsippany, New Jersey 07054, as more particularly described in the Lease (the “Premises”), and located in the project commonly known as Hanover Business Center #1 (the “Project”). Capitalized terms used herein but not otherwise defined shall have the meanings ascribed thereto in the Lease.

WHEREAS, Landlord and Tenant desire to amend the terms and conditions of the Lease to reflect the extension of the Term and to correct the Scrivener’s Error, in each case as hereinafter provided.

IN WITNESS WHEREOF, the parties hereto have caused this Amendment to be duly authorized, executed and delivered as of the day and year first set forth above.

EXHIBIT A

LANDLORD’S WORK

(a)           Landlord’s Work. Landlord agrees to perform or cause to be performed that certain construction, repair, maintenance, or those certain improvements to the Premises as specified below (the “Landlord’s Work”), without warranty and using Landlord’s standard building materials and finishes:

1.          Install five (5) exterior man doors throughout the facility; and

2.          Install one (1) loading dock door in the warehouse portion of the Premises.

(b)           Substantial Completion. The Landlord’s Work shall be deemed substantially completed (“Substantially Completed” or “Substantial Completion”) when, in the opinion of the construction manager (whether an employee or agent of Landlord or a third party construction manager, the “Construction Manager”), the Landlord’s Work are substantially completed except for punch list items which do not prevent in any material way the use of the Premises for the purposes for which they were intended. In the event Tenant, its employees, agents, or contractors cause, directly or indirectly, the construction or completion of the Landlord’s Work to be delayed, then the date of Substantial Completion shall be deemed to be the date that, in the opinion of the Construction Manager, Substantial Completion would have occurred if such delays or impairments had not taken place. Without limiting the foregoing, Tenant shall be solely responsible for delays caused by Tenant’s request for any changes in the plans, Tenant’s request for long lead items, Tenant’s failure to provide Landlord with reasonable access to the Premises to undertake the Landlord’s Work, and/or Tenant’s interference with the construction of the Landlord’s Work, and such delays shall not entitle Tenant to any abatement of rent or other rights of any kind. Substantial Completion is only material for purposes of determining the completion of the Landlord’s Work and has no impact whatsoever on the Extended Term Commencement Date and/or Tenant’s other obligations under the Lease, including, without limitation, the obligation to pay rent. In no event shall Landlord have any obligation for any defects in the Landlord’s Work or any limitation on its use; provided, however, Landlord agrees, at Tenant’s cost, to seek enforcement of any warranty issued by any contractor or other party performing the Landlord’s Work. Landlord agrees to use commercially reasonable efforts to cause the Landlord’s Work to be performed in a good and workmanlike manner.

(c)           Access. From and after the date of execution of this Amendment, Tenant shall provide Landlord with all reasonably necessary access to the Premises, and shall cooperate with Landlord in all reasonable respects, to undertake and complete the Landlord’s Work, it being understood that Tenant shall not be entitled to any abatement of rent or claims of any kind against Landlord in connection with any inconvenience or accommodations which are required by Landlord, or in connection with any interference with Tenant’s business operations or damage to any of Tenant’s property, as part of the completion of the Landlord’s Work. Tenant, at its sole cost and expense and prior to the commencement of the Landlord’s Work, shall promptly remove all personal property, trade fixtures, equipment, office furniture and/or other similar items, if any, as may be reasonably required by Landlord for Landlord to undertake and complete the Landlord’s Work.

EXHIBIT B

TENANT’S WORK

(a)           Tenant’s Work. Landlord shall contribute up to a maximum amount of $306,000.00 (the “Allowance”) towards Tenant’s alterations and improvements to the Premises as specified below (collectively, the “Tenant’s Work”):

(b)           Landlord’s Approval; Tenant’s Obligations. The Tenant’s Work shall be subject to the terms of Section 11 of the Original Lease. In addition to obtaining Landlord’s consent as and when required pursuant to Section 11 of the Original Lease, Tenant shall obtain Landlord’s prior written consent for any of the Tenant’s Work for which Tenant will seek reimbursement from the Allowance. In all cases, Tenant shall deliver plans and specifications for the Tenant’s Work (except with respect to Building-standard painting and carpet installation), and any other documentation reasonably requested by Landlord, to Landlord for approval prior to commencing any of the Tenant’s Work. All of the Tenant’s Work shall be constructed and undertaken in a good and workmanlike manner and in compliance with all applicable laws, and Tenant shall perform, at its expense, any alteration or modification required by any applicable laws as a result of the Tenant’s Work. Landlord may monitor the construction of the Tenant’s Work, subject to the obligation to provide prior notice to Tenant of any entry onto the Premises (except in the case of emergency, in which case no prior notice is required). Landlord’s right to approve the Tenant’s Work and to monitor construction shall be solely for its own benefit, and Landlord shall have no duty to see that the Tenant’s Work complies with any applicable laws.

(c)           Allowance. The Allowance may be used only for the hard costs and Eligible Soft Costs (as hereinafter defined) of construction of the Tenant’s Work pursuant to the approved plans and specifications. “Eligible Soft Costs” shall be deemed to be costs and expenses incurred by Tenant which are directly and primarily related to the Tenant’s Work and which relate solely to the work of any architect, space planner, engineer, or similar construction professional or which are direct payments made to applicable authorities for permitting and license fees: provided, however, that in no event shall the Eligible Soft Costs exceed fifteen percent (15%) of the total Allowance or be used for services provided in connection with the negotiation of the Lease. For the avoidance of doubt, Eligible Soft Costs shall expressly exclude any financing costs, attorneys’ fees, or other costs and expenses not expressly permitted hereunder. In no event will the Allowance be used to pay for moving or storage expenses or furniture, racking, equipment, cabling, telephone systems or any other item of personal properly which is not intended to be permanently affixed to the Premises. Payment of the Allowance shall be made by Landlord to Tenant within thirty (30) days following the last to occur of: (i) completion of the Tenant’s Work, (ii) Landlord’s receipt of Tenant’s invoice substantiating the costs related thereto, (iii) Landlord’s receipt of final lien waivers from all contractors and subcontractors who performed the Tenant’s Work, and (iv) Landlord’s receipt of a copy of the final permit approved by the applicable governing authority for any work which requires the same. Landlord shall be under no obligation to pay for any of the Tenant’s Work in excess of the Allowance. Further, the Allowance shall only be available for Tenant’s use for work performed and submitted for reimbursement in accordance with the terms of this Exhibit on or before November 30, 2016, after which date Tenant hereby waives any and all rights to any unused portion of the Allowance.

EXHIBIT C

RENEWAL OPTION

Notwithstanding anything to the contrary in the Lease, Tenant shall have one (1) option to renew the Term (the “Renewal Option”) on the following terms and conditions:

(a)          Provided that as of the date of the receipt of the Renewal Notice (as hereinafter defined) by Landlord and the Renewal Commencement Date (as hereinafter defined), (i) Tenant is the tenant named on the Lease as of the Extended Term Commencement Date, (ii) Tenant actually occupies all of the Premises, and (iii) no default exists, or would exist but for the passage of time or the giving of notice, or both, then Tenant shall have the right to extend the Term for an additional term of sixty (60) months (the “Renewal Term”) commencing on the day following the expiration of the Extended Term (the “Renewal Commencement Date”). Tenant shall give Landlord written notice (the “Renewal Notice”) of its election to renew the Term in accordance with the terms hereof at least nine (9) months, but not more than twelve (12) months, prior to the scheduled expiration date of the Extended Term.

(b)          The Base Rent payable by Tenant to Landlord during the Renewal Term shall be the greater of (i) the Base Rent applicable to the last year of the Extended Term, and (ii) the then-prevailing market rate for comparable space in comparable buildings in the vicinity of the Project taking into account the size of the Lease, the length of the renewal term, market escalations, and the credit of Tenant. The Base Rent shall not be reduced by reason of any costs or expenses saved by Landlord by reason of Landlord’s not having to find a new tenant for such premises (including, without limitation, brokerage commissions, costs of improvements, rent concessions or lost rental income during any vacancy period).

(c)          Landlord shall notify Tenant in writing of its determination of the Base Rent (which shall be made in Landlord’s sole discretion) for the Renewal Term within ten (10) days following Landlord’s receipt of the Renewal Notice, and Tenant shall advise Landlord in writing of any objection within ten (10) days of receipt of Landlord’s notice. Failure to respond within the ten (10) day period shall constitute Tenant’s acceptance of such Base Rent. If Tenant objects, Landlord and Tenant shall commence negotiations to attempt to agree upon the Base Rent for a period of up to fifteen (15) days after Landlord’s receipt of Tenant’s objection notice. If the parties cannot agree, each acting in good faith but without any obligation to agree, on the Base Rent on or before the end of such fifteen (15) day period, then Tenant’s exercise of the Renewal Option shall be deemed withdrawn and the Lease shall expire or terminate in accordance with its terms.

(d)          The determination of the Base Rent does not reduce Tenant’s obligation to pay or reimburse Landlord for operating expenses, real estate taxes and assessments, and any other reimbursable or chargeable items as set forth in the Lease, and Tenant shall reimburse and pay Landlord as set forth in the Lease with respect to such items with respect to the Premises during the Renewal Term.

(e)          Except for the Base Rent for the Renewal Term as determined above, Tenant’s occupancy of the Premises during the Renewal Term shall be on the same terms and conditions as are in effect immediately prior to the expiration of the Extended Term; provided, however. Tenant shall have no further right to any allowances, credits or abatements or any options to expand, contract, renew, terminate or extend the Lease.

(f)          If Tenant does not give the Renewal Notice within the period set forth above, the Renewal Option shall automatically terminate. Time is of the essence as to the giving of the Renewal Notice.

(g)          Landlord shall have no obligation to refurbish or otherwise improve the Premises for the Renewal Term. The Premises shall be tendered on the Renewal Commencement Date in “as-is” condition.

(h)          If the Lease is extended for the Renewal Term, then, promptly after the determination of Base Rent in accordance with the terms of this exhibit, Landlord shall prepare and Tenant shall execute an amendment to the Lease confirming the extension of the Term and the other provisions applicable thereto.

(i)          If Tenant exercises its right to renew the term of the Lease for the Renewal Term pursuant to this exhibit and the parties execute the amendment, the term “Term” as used in the Lease shall be construed to include, when practicable, the Renewal Term except as provided in subparagraph (e) above.
