EXECUTION COPY

confirm the Company’s title to or interest in the Transferred Assets, to put the Company in actual possession and operating control thereof and to assist the Company in exercising all rights with respect thereto. In addition, if, following the transfer of the Transferred Assets, the Company identifies specific items within the Transferred Assets that were not transferred to the Company, TDCC and/or DGTI, as applicable, shall use all reasonable efforts to transfer such items to the Company.

Notwithstanding any provision herein, Sections 4.4 and 4.5 shall continue in full force and effect after the Closing until their expiration in accordance with Section 7.1.

RECITALS

A. Pursuant to that certain Lease dated as of December 20, 2007, by and between Sublessor and ECI TWO OBERLIN LLC, a Delaware limited liability company (“Master Lessor”) (collectively and as amended or renewed from time to time, the “Master Lease”), Sublessor leased from Master Lessor certain premises (as set forth more particularly in the Master Lease, the “Final Premises”) located in a project located in San Diego, California (as set forth in the Master Lease, the “Project”). As of the date hereof, the Final Premises is comprised of the Building A Premises (as defined in the Master Lease) and the Building C Premises (as defined in the Master Lease).

B. Sublessor desires to sublease to Sublessee, and Sublessee desires to sublease from Sublessor, the entire Final Premises as shown on Exhibit “A” attached hereto (the “Subleased Premises”) and all improvements and fixtures located thereon, upon the terms and conditions set forth herein.

C. Capitalized terms used herein but not otherwise defined herein shall have the meanings set forth in the Master Lease.

NOW, THEREFORE, in consideration of the foregoing recitals and of the mutual promises and covenants contained herein, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

1. Subleased Premises. Subject to all of the terms and conditions set forth herein, Sublessor hereby subleases to Sublessee, and Sublessee hereby subleases from Sublessor the Subleased Premises. Sublessor and Sublessee acknowledge and agree that there are 27,292 Rentable Square Feet in the Building A Premises and 4,768 Rentable Square Feet in the Building C Premises and Sublessee shall have no right to remeasure or otherwise contest the Rentable Square Feet in either space for any purpose.

2. Term.

2.1 Initial Term. The term of this Sublease (“Sublease Term”) shall commence on the later of (a) December 1, 2009, and (b) the closing of the transaction transferring certain assets of Sublessor to Sublessee (the “Commencement Date”) and shall expire on March 15, 2011 unless sooner terminated pursuant to any provision hereof.

2.2 Automatic Termination. This Sublease shall terminate automatically upon any expiration or earlier termination of the Master Lease and Sublessor shall not be liable to Sublessee by reason thereof.

3. Condition of Subleased Premises; Improvements. Sublessee acknowledges that it has inspected the Subleased Premises and agrees to accept the same in an “AS-IS”, “WHERE-IS” condition, without any representation or warranty, express or implied, being made by Sublessor. Sublessee further accepts the Subleased Premises subject to all applicable zoning, municipal, county and state laws,

-2-

ordinances, and regulations governing and regulating the use of the Subleased Premises. Sublessee acknowledges that neither Sublessor nor Sublessor’s agents have made any representation or warranty as to the suitability or fitness of the Subleased Premises for the conduct of Sublessee’s use, the physical condition or the fitness for any particular purpose of all or any part of the Subleased Premises as an inducement to Sublessee to enter into this Sublease or for any other purpose. Sublessor shall have no obligation to make any alterations or improvements in the Subleased Premises or to provide any allowance therefor.

4. Rent.

4.1 Monthly Base Rent. Commencing on the Commencement Date and continuing throughout the Sublease Term, Sublessee shall pay to Sublessor Monthly Base Rent for the Subleased Premises equal to Forty Thousand Seventy-Five and 00/100 Dollars ($40,075.00) (based on $1.25 per Rentable Square Foot in the Subleased Premises). Sublessee shall, concurrently with execution hereof, pay Sublessor its first monthly installment of Monthly Base Rent.

4.2 Additional Rent; Building Costs; Property Taxes. Commencing on the Commencement Date, Sublessee shall be obligated to pay all additional rent (as described in Section 5(b) of the Master Lease) payable by Sublessor under the Master Lease, including, without limitation, all Operating Expense payments due and payable under the Master Lease (“Additional Rent”). In addition to the Monthly Base Rent and Additional Rent which are expressly provided for above, Sublessee shall be responsible throughout the Sublease Term for all other payments or charges arising or accruing under the Master Lease during the Sublease Term including, without limitation, the following: (a) any charges relating to any special privilege or services provided to Sublessee (or its subtenants, assignees or anyone claiming by, through or under Sublessee) such as HVAC and freight elevator service for which Sublessor is separately charged by Master Lessor; (b) any indemnity payments relating to the Subleased Premises not attributable to any act of Sublessor; (c) any claims for damages or other losses resulting from a casualty to the Subleased Premises; (d) any claims by Master Lessor for reimbursement resulting from Master Lessor’s exercise of self help remedies in the Subleased Premises, and (e) any utility charges due and payable under the Master Lease (collectively, items (a) through (e) shall be included in the definition of Additional Rent).

4.3 Payment of Rent. Monthly Base Rent shall be paid in advance on the first day of each calendar month, at such address as Sublessor shall, from time to time, specify in writing. If the date of termination of this Sublease is not the last day of a calendar month, then rent for the last month of this Sublease shall be prorated. All Additional Rent shall be paid to Sublessor within five (5) days of demand and before it becomes delinquent under the Master Lease. Monthly Base Rent, Additional Rent and all other amounts due under this Sublease shall be deemed to be rent (“Rent”). Except as otherwise expressly provided under this Sublease, all Rent shall be paid by Sublessee without notice, demand, deduction, offset or abatement in lawful money of the United States.

5. Use of the Subleased Premises.

5.1 Permitted Use. The Subleased Premises shall be used and occupied only for the uses set forth in Section 7(a) of the Master Lease, and for no other purpose.

5.2 Alterations; Compliance with Law. Sublessee shall not be permitted to make alterations to the Subleased Premises without the prior written consent of Sublessor which consent shall not be unreasonably withheld or delayed (and otherwise in compliance with and to the extent allowed under the Master Lease). Sublessee shall, at its sole expense, comply promptly with all applicable statutes, ordinances, rules, regulations, orders, restrictions of record, and requirements in effect during the term hereof (or any part of such term) regulating its use of the Subleased Premises.

-3-

5.3 Maintenance of Subleased Premises. Sublessee agrees that it shall use and maintain the Subleased Premises in a first class condition and otherwise as required by the Master Lease.

5.4 Surrender. Upon the expiration or termination of this Sublease, Sublessee shall return the Subleased Premises in the same condition (reasonable wear and tear excepted) and in the same configuration as of the date hereof (including any renovations thereto, which shall become part of the Subleased Premises), unless otherwise required by Sublessor or the Master Lessor.

6. Building Services. Sublessor shall have no obligation during the Sublease Term (whether under the Master Lease or otherwise) to render any services to the Premises or to expend any money for the repair of or perform any obligation for Sublessee in, to or with respect to the Subleased Premises of any nature whatsoever. Sublessor specifically is not responsible for providing security to the Subleased Premises and shall have no liability whatsoever to Sublessee for loss, damage or theft of or to Sublessee’s property.

7. Master Lease.

7.1 Sublessor’s Compliance with Master Lease. Sublessee expressly agrees that Sublessor shall not be obligated to perform, and shall not be liable or responsible for the performance by or failure of performance of Master Lessor, of any of the obligations of Master Lessor under the Master Lease and Sublessee shall have no claim against Sublessor for any default of Master Lessor. Sublessee further agrees that Sublessor shall not be obligated to perform any of the obligations of Sublessor as tenant under the Master Lease and Sublessee shall have no claim against Sublessor for any such non-performance, including, without limitation, any termination or forfeiture of the Master Lease caused by Sublessor.

7.2 Application of Terms of Master Lease. The terms, conditions and respective obligations of Sublessor and Sublessee to each other with respect to the Subleased Premises under this Sublease shall be the terms and conditions of the Master Lease (which are incorporated herein by reference), except for those provisions of the Master Lease which are directly contradicted by this Sublease (e.g., Sections 1(i), 1(k), and 3 of the Master Lease), in which event the terms of this Sublease shall control over the Master Lease. Therefore, for the purposes of this Sublease and with respect to the Subleased Premises only, wherever in the Master Lease the word “Landlord” is used it shall be deemed to mean Sublessor herein and wherever in the Master Lease the word “Tenant” is used it shall be deemed to mean Sublessee herein; provided, however, Sublessor does not assume and shall not otherwise be liable for the obligations of the Master Lessor under the Master Lease. Sublessee hereby waives any cause of action and any right to bring any action against Sublessor by reason of any act or omission of Master Lessor under the Master Lease. Any condition resulting from a default by Master Lessor shall not constitute as between Sublessor and Sublessee an eviction, actual or constructive, of Sublessee and no such default shall excuse Sublessee from the performance or observance of any of its obligation under this Sublease or entitle Sublessee to any rental abatement hereunder.

7.3 Subordinate to Master Lease. This Sublease is and shall be at all times subject and subordinate to the Master Lease. Sublessee acknowledges that this Sublease is subject and subordinate to the Master Lease and that this Sublease shall be subject and subordinate to all agreements which have recorded or statutory priority over this Sublease or the Master Lease. Notwithstanding any provision of this Lease to the contrary, the expiration or termination of this Sublease and/or the Master Lease and/or the termination of Sublessee’s rights to possession of the Subleased Premises shall not discharge, relieve or release Sublessee from any obligation or liability whatsoever under any indemnity provision of this Sublease.

-4-

7.4 No Greater Rights. Any obligation of Sublessor which is contained in this Sublease by the incorporation by reference of the provisions of the Master Lease may be observed or performed by Sublessor using reasonable efforts to cause the Master Lessor under the Master Lease to observe and/or perform the same, and Sublessor shall have a reasonable time to enforce its rights to cause such observance or performance. Sublessee shall not in any event have any rights in respect of the Subleased Premises greater than Sublessor’s rights under the Master Lease.

7.5 Sublessee Not to Breach. Sublessee shall not do or permit to be done any act or thing which may constitute a breach or violation of any term, covenant or condition of the Master Lease by the tenant thereunder, whether or not such act or thing is permitted under the provisions of this Sublease.

7.6 Insurance Required Under Master Lease. Sublessee shall be responsible, at its own cost and expense, for obtaining and maintaining relative to the Subleased Premises, all that insurance (including coverage for possessions and general liability) as is required by the Master Lease to be carried by the “Tenant” thereunder. Sublessee’s insurance shall be issued by an insurance company or companies approved by Sublessor and the Master Lessor, and shall be written on such forms with such exclusions and deductible amounts as Sublessor shall approve. The policy or policies shall name Sublessor and Master Lessor as additional insureds and shall include thirty (30) days’ advance written notice to Sublessor prior to the cancellation or material reduction in coverage of such insurance policies.

8. Signage. Sublessee shall not cause, suffer or permit any person to display any signs or notices at the Subleased Premises without the prior written consent of Master Lessor and Sublessor. All signage shall be at Sublessee’s sole cost and expense.

9. Brokerage. Each party represents and warrants to the other that no broker or finder has been engaged by it, respectively, in connection with any of the transactions contemplated by this Sublease or to its knowledge is in any way connected with any of such transactions. In the event of a claim for broker’s or finder’s fee or commissions in connection herewith, Sublessor shall indemnify, protect, defend and hold Sublessee harmless from and against the same if it shall be based upon any statement or agreement alleged to have been made by Sublessor, and Sublessee shall indemnify, protect, defend and hold Sublessor harmless from and against the same if it shall be based upon any statement or agreement alleged to have been made by Sublessee. The parties’ respective indemnification obligations under this paragraph shall survive the termination or expiration of this Sublease.

10. Indemnification

10.1 In General. Sublessee hereby agrees to indemnify, defend, protect and hold Sublessor, its affiliates, employees, officers, directors, agents and representatives, and the Master Lessor and each of their respective successors and assigns, harmless from and against any and all losses, liabilities, costs (including costs of cure, remedy or settlement made by Sublessor), damages, demands, and expenses (including costs of investigation, defense and reasonable attorneys’ fees, whether or not litigation, arbitration or mediation is actually instigated or commenced) from the payment of, or the obligation to pay, any and all sums of money due or demanded by any person or entity whatsoever on account of any and all claims, demands, suits, actions, liens, settlements, judgments, garnishments or attachments (collectively, “Losses”), arising out of or in connection with (a) the acts, omissions or negligence of Sublessee or its employees, agents, contractors and invitees; (b) the breach of the Master Lease by Sublessee and/or default by Sublessee in the observance of its terms, covenants or conditions and any cure undertaken by Sublessor with respect thereto; (c) the breach of this Sublease by Sublessee and any default in the observance of its terms, covenants or conditions; (d) the use of the Premises or Subleased Premises by Sublessee or its employees, agents, contractors and invitees or any person claiming by, through or under Sublessee; (e) any injury or death of any person (including, without limitation, any employee of Sublessor or any damage to or destruction of any property of any person (including, without

-5-

limitation, any employee of Sublessor occurring on or about the Premises); or (f) any and all actions, suits, proceedings, claims and demands taken or made in enforcing this indemnity. The provisions of this Section 10 shall survive the expiration or earlier termination of this Sublease. Sublessor shall not be liable for and Sublessee hereby waives all claims against Sublessor for any damage to any property or injury, illness or death of any person in, upon, or about the Premises arising at any time and from any cause whatsoever.

10.2 Defense by Sublessee. In connection with any claim giving rise to indemnity hereunder resulting from or arising out of any claim or legal proceeding by any third party, Sublessee, at its sole cost and expense, shall assume the defense of any such claim or legal proceeding using counsel of Sublessor’s choice. Sublessor shall be entitled to participate in the defense of any such action, with its counsel and at its own expense; provided, however, that if Sublessor, in its reasonable discretion, determines that there exists a conflict of interest between the Sublessee (or any constituent party thereof) and Sublessor, Sublessor shall have the right to engage separate counsel, the actual costs and expenses of which shall be paid by Sublessee.

11. Default. In the event of a default by Sublessee under this Sublease which continues after the giving of any notice and the expiration of any cure period provided for a like default under the Master Lease, Sublessor shall have available to it under this Sublease all remedies which are available to Master Lessor under the Master Lease, including the imposition of late charges and interest on delinquent payments.

12. Assignment/Subletting. Sublessee’s rights to assign, sublease, pledge, encumber, hypothecate or otherwise transfer (each, a “Transfer”) all or any part of Sublessee’s interest in this Sublease, or permit the Subleased Premises to be occupied by anyone other than Sublessee, shall be in accordance with and subject to all provision of Section 23 of the Master Lease.
