As of the New Premises Commencement Date, the following shall be effective: a) Tenant shall relocate from the Demised Premises consisting of approximately 5,525 square feet on the 6th floor of the Building ("Existing Premises") to space located on the 7th floor of the Building consisting of approximately 11,432 square feet ("New Premises") as shown on the floor plan attached and made a part hereof as Exhibit A-1. All references in the Lease to the Demised Premises shall apply to the New Premises. Tenant shall surrender the Existing Premises in accordance with the Lease within fourteen (14) days following the New Premises Commencement Date.

Tenant shall deposit such additional security in the amount of $48,904.92 upon Tenant's execution and delivery of this First Amendment. 3. The New Premises Commencement Date shall be deemed to occur on the earlier of (i) the date the New Premises shall be deemed complete (as defined below) or (ii) the date Tenant or anyone claiming under or through Tenant shall occupy the New Premises. The New Premises shall be deemed complete on the earliest date on which Landlord's work, as set forth on Exhibit A-1, in the New Premises has been substantially completed, notwithstanding the fact that minor or insubstantial details of construction, mechanical adjustment or decoration remain to be performed, the non-completion of which would not materially interfere with Tenant's use of the New Premises. Landlord shall notify Tenant in writing of substantial completion of Landlord's work and shall specify all outstanding items, if any, and the estimated date of completion. If completion of the New Premises is delayed by reason of: (i) any act or omission of Tenant or any of its employees, agents or contractors which affects the Landlord's ability to complete the work, or (ii) failure to plan or execute Tenant's work, if any, with reasonable speed and diligence, or (iii) failure to make selections required hereunder, or (iv) material changes by Tenant in its drawings or specifications or changes or substitutions requested by Tenant, or (v) failure to timely submit or approve drawings, plans or specifications, (vi) Tenant's failure to deliver to Landlord the additional security deposit required hereunder, then the New Premises shall be deemed complete (and Tenant shall commence paying the rental set forth in Paragraph 2 (b)) on the date when it would have been completed but for such delay, and Tenant shall pay Landlord all costs and damages which Landlord may sustain as a direct result of a Tenant's delay as specified in paragraphs 3(i)-(vi) above. Promptly following the completion of the New Premises as described above, the parties shall enter into a supplementary written agreement setting forth the New Premises Commencement Date. 4. Tenant agrees not to disclose the terms, covenants, conditions or other facts with respect to the Lease, including, but not limited to, the fixed rent, to any person, corporation, partnership, association, newspaper, periodical or other entity. This non-disclosure and confidentiality agreement shall be binding upon Tenant without limitation as to time, and a breach of this paragraph shall constitute a material breach under the Lease. 5. The Tenant represents that it has dealt with no broker in connection with this First Amendment except Mack-Cali Realty, L.P. 6. Except as otherwise set forth herein, all terms and provisions contained in the Lease shall remain in full force and effect. 7. It is understood and agreed that this First Amendment is submitted to the Tenant for signature with the understanding that it shall not bind the Landlord unless and until it has been executed by the Landlord and delivered to the Tenant or Tenant's attorney. 8. This Lease, as hereby amended, shall be binding upon the parties hereto, their successors and assigns. IN WITNESS WHEREOF, the parties hereto have hereunto set their hands and seals the day and year first above written. GLORIOUS SUN ROBERT MARTIN, LLC By: RM Blue Hill, Inc.
