D.                                   Tenant and Landlord agree to (i) relocate Tenant from the Second Floor Suites to approximately 19,881 rentable square feet of space comprising the entire fourth (4^th) floor of the 3020 Building as shown on Exhibit “A” attached hereto (the “Substitution Space”), (ii) make the Subleased Space subject to the terms of the Lease and (iii) extend the Term of the Lease with respect to Suite 440, all on the following terms and conditions.

NOW, THEREFORE, in consideration of the mutual covenants and agreements herein contained and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Landlord and Tenant agree as follows:

1.                                      Substitution.

A.                                   Effective as of the Substitution Effective Date (hereinafter defined), the Substitution Space is substituted for the Second Floor Suites, and, from and after the Substitution Effective Date, the “Premises”, as defined in the Lease, shall be deemed to mean the Substitution Space containing approximately 19,881 rentable square feet, the Subleased Space containing approximately 5,060 rentable square feet and Suite 440 containing approximately 6,136 rentable square feet (as more particularly described below) (i.e., the entire Premises shall contain approximately 31,077 rentable square feet).

B.                                    The Substitution Effective Date shall be delayed to the extent that Landlord fails to deliver possession of the Substitution Space for any other reason (other than delays caused by Tenant), including, but not limited to, holding over by prior occupants.  Any such delay in the Substitution Effective Date shall not subject Landlord to any liability for any loss or damage resulting therefrom.

C.                                    Landlord shall use commercially reasonable efforts to give Tenant’s designated contractor access to the Substitution Space by August 1, 2008 (the “Early Access Period”) for purposes of installing Tenant’s fixtures and equipment, including Tenant’s telephone and data cabling, and other improvements in the Substitution Space in accordance with Section 6 of the Original Lease (“Tenant’s Work”).  Tenant’s Work shall be performed by Tenant at Tenant’s sole cost and expense.  Tenant’s use of the Substitution Space during the Early Access Period shall be subject to all of the terms and conditions of the Lease, including, without limitation, the provisions of Sections 6, 10 and 11 of the Original Lease, except that Tenant will not be obligated to pay monthly Base Rent or any Additional Rent during the Early Access Period.  Tenant agrees to provide Landlord with prior notice of any such intended early access.

3

Sublease terminates pursuant to said termination agreement entered into by Tenant and Baker.  In the event that Tenant and Baker enter into said termination agreement of the Baker Sublease, Tenant shall provide Landlord with written notice thereof within five (5) days of Tenant and Baker signing said termination agreement.  During the Subleased Space Term, (i) Tenant shall pay Landlord Base Rent for the Subleased Space in accordance with the terms of the Amended Lease in the amount of $12,903.00 per month and (ii) Tenant’s Share of Operating Costs and Taxes for the Subleased Space shall be 1.767% and Tenant shall pay for Tenant’s Share of Operating Costs and Taxes for the Subleased Space in accordance with the terms of the Original Lease; provided, however, during such period, the Base Year for the computation of Tenant’s Share of Operating Costs and Taxes applicable to the Subleased Space shall be calendar year 2007.  Effective as of the expiration of the Subleased Space Term, the Amended Lease shall be terminated with respect to the Subleased Space and Tenant shall vacate the Subleased Space and return the same to Landlord in “broom clean” condition and otherwise in accordance with the terms and conditions of the Lease.  Following the expiration of the Subleased Space Term, however, Tenant’s obligation for payment of monthly Base Rent or Additional Rent on the Subleased Space shall be determined in accordance with Section 9 hereof.

6

for such reserved parking spaces as Additional Rent under the Amended Lease.  Tenant shall not use more parking spaces than its allotment and shall not use any parking spaces specifically assigned by Landlord to other tenants of the Building.

On each anniversary of the Substitution Effective Date, said reserved parking fees charged to Tenant for said twenty-four (24) reserved parking spaces applicable to the Substitution Space, the Subleased Space and Suite 440 shall increase by three percent (3%) of the previous year’s parking fees.  Effective as of the Substitution Effective Date, the first two (2) sentences of Section 36(a) of the Original Lease are deleted in their entirety, and except as modified herein, the use of the parking spaces shall be subject to the terms of Article 36 of the Original Lease.

11.                                 Signage.  Effective as of the Substitution Effective Date and subject to the terms of this Section 11, Tenant shall have the right to install one (1) building top sign in a mutually agreeable location on the 3030 Building (the “Exterior Sign”).  Notwithstanding the foregoing, Tenant shall not be entitled to install the Exterior Sign if:  (a) Tenant has previously assigned its interest in the Amended Lease, (b) excepting the sublease of the Baker Subleased Space pursuant to the Baker Sublease, Tenant has previously sublet any portion of the Premises, or (c) Tenant is in default under any monetary or material non-monetary provision of the Amended Lease.  Furthermore, Tenant’s right to install the Exterior Sign is expressly subject to and contingent upon Tenant receiving the approval of and consent to the Exterior Sign from Landlord (which approval and consent shall not be unreasonably withheld) and the City of Seal Beach, California, its architectural review board, any other applicable governmental or quasi-governmental governmental agency and any architectural review committee under the covenants, conditions and restrictions recorded against the Project.  Tenant, at its sole cost and expense, shall obtain all other necessary building permits, zoning, regulatory and other approvals in connection with the Exterior Sign.  All costs of approval, consent, design, installation, supervision of installation, wiring, maintaining, repairing and removing the Exterior Sign will be at Tenant’s sole cost and expense.  Tenant shall submit to Landlord reasonably detailed drawings of its proposed Exterior Sign, including without limitation, the size, material, shape, location, coloring, lettering and method of installation for review and approval by Landlord.  The Exterior Sign shall conform to the Building signage program and the other reasonable standards of design and motif established by Landlord for the exterior of the Building.  The Exterior Sign shall also be subject to (i) Landlord’s prior review and written approval thereof, and (ii) the terms, conditions and restrictions of any recorded covenants, conditions and restrictions encumbering the Project and/or the Building.  Tenant shall reimburse Landlord for any reasonable out-of-pocket costs associated with Landlord’s review and supervision as hereinbefore provided including, but not limited to, engineers and other professional consultants.  Tenant will be solely responsible for any damage to the Exterior Sign and any damage that the installation, maintenance, repair or removal thereof may cause to the Building or the Project.  Tenant agrees upon the expiration date or sooner termination of the Amended Lease, upon Landlord’s request, to remove the Exterior Sign and restore any damage to the Building and the Project at Tenant’s expense.  In addition, Landlord shall have the right to remove the Exterior Sign at Tenant’s sole cost and expense, if, at any time during the Term:  (i) Tenant assigns the

7

Amended Lease, (ii) excepting the sublease of the Baker Subleased Space pursuant to the Baker Sublease, Tenant sublets any portion of the Premises, or (iii) Tenant is in default under any term or condition of the Amended Lease.  Notwithstanding anything to the contrary contained herein, if Tenant fails to install the Exterior Sign on the Building in accordance with the terms of this Section 11 on or before the eighth (8th) month anniversary of the Substitution Effective Date (the “Outside Exterior Sign Installation Date”), Tenant’s right to erect any such Exterior Sign shall terminate as of the Outside Exterior Sign Installation Date and shall thereupon be deemed null and void and of no further force and effect.

In addition to the foregoing, Landlord and Tenant acknowledge and agree that as of the date of this Amendment, Tenant has existing signage located on the 3010 Building (the “3010 Signage”).  As a condition to Tenant’s right to install the Exterior Sign on the 3030 Building, Tenant shall remove the 3010 Signage and repair any damage to the 3010 Building and the Project at Tenant’s expense no later than the Vacation Date.

12.           Business Hours.  Effective as of the date of this Amendment, the Basic Lease Information of the Lease is revised to provide that “Building Hours” are 7:00 a.m. to 6:00 p.m. on Business Days.

13.                                 Miscellaneous.

A.                                   Tenant represents and warrants to Landlord that neither Tenant nor any guarantor of Tenant’s obligations under the Amended Lease is (a) a party in interest, as defined in Section 3(14) of the of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), to the AFL-CIO Building Investment Trust (“Trust”), or of any of the plans participating therein, or (b) a disqualified person under Section 4975(e)(2) of the Internal Revenue Code of 1986, as amended (“Code”), with respect to the Trust or the plans participating therein.  Neither Tenant nor any guarantor of Tenant’s obligations under the Amended Lease shall take any action that would cause the Amended Lease or the exercise by Landlord or the Trust of any rights hereunder, to be a non-exempt prohibited transaction under ERISA.  Notwithstanding any contrary provision of the Amended Lease, Tenant shall not assign the Lease or sublease all or any portion of the Premises unless (i) such assignee or subtenant delivers to Landlord a certification (in form and content satisfactory to Landlord) with respect to the status of such assignee or subtenant (and any guarantor of such assignee’s or subtenant’s obligations) as a party in interest and a disqualified person, as provided above; and (ii) such assignee or subtenant undertakes not to take any action that would cause the Amended Lease or the exercise by Landlord or the Trust of any rights hereunder, to constitute a non-exempt prohibited transaction under ERISA.

Notwithstanding any contrary provision of the Amended Lease, Tenant shall not (a) sublease all or any portion of the Premises under a sublease in which the rent is based on the net income or net profits of any person, or (b) take any other action with respect to the Amended Lease or the Premises such that the revenues to be

8

received by Landlord or the Trust from time to time in connection with the Lease would, as a result of such action, be subject to the Unrelated Business Income Tax under Sections 511 through 514 of the Code.

Tenant agrees that it shall incorporate the requirements of this Section 13(A) in any sublease of all or any part of the Premises (without implying Landlord’s consent thereto).

B.                                     Tenant shall use Union Labor (defined below) for all maintenance, repair, and replacement of the Premises (the “Maintenance Labor Covenant”).  Notwithstanding the foregoing, the Maintenance Labor Covenant shall not apply to (i) the services for installation, operation, maintenance and repair of personal property owned exclusively by Tenant (e.g., computer systems, telephones, and furniture other than modular furniture) or for any of Tenant’s specialized equipment, (ii) a specific item or instance of maintenance, repair or replacement to the extent Union Labor is not available in the market to perform such specific item or instance of maintenance, repair or replacement, and/or (iii) maintenance, repairs and replacements that may be and are self-performed by the existing staff of Tenant without the retention, engagement or hiring of any third party or additional employee.  Tenant shall (a) include the Maintenance Labor Covenant in each of its service contracts, (b) provide such evidence as Landlord may reasonably require, from time to time during the Lease Term, that the Maintenance Labor Covenant is being fully and faithfully observed and Tenant shall include the obligation to provide such evidence in each service contract entered into by Tenant for such services, and (c) incorporate the foregoing requirements in any sublease, license, or occupancy agreement relating to all or any part of the Premises (without implying Landlord’s consent to same).

In addition to any other conditions contained in the Amended Lease with respect to Tenant making any alterations or improvements, before making any alterations or improvements to the interior or exterior of the Premises, Tenant shall (a) deliver to Landlord evidence satisfactory to Landlord that Tenant shall cause such construction or alteration work (collectively, the “Construction Activities”) to be performed by contractors who employ craft workers who are members of unions that are affiliated with The Building and Construction Trades Department, AFL-CIO (“Union Labor”), and such work shall conform to traditional craft jurisdictions as established in the area (the “Construction Labor Covenant”), (b) include the Construction Labor Covenant in each of its contracts for the Construction Activities, (c) provide such evidence as Landlord may reasonably require, from time to time during the course of the Construction Activities, that the Construction Labor Covenant is being fully  and faithfully observed and Tenant shall include the obligation to provide such evidence in each contract entered into by Tenant for the Construction Activities, and (d) incorporate the foregoing requirements in any sublease, license, or occupancy agreement relating to all or any part of the Premises (without implying Landlord’s consent to same).  Tenant shall require that all contractors and subcontractors, of whatever tier, performing Construction Activities agree to submit all construction jurisdictional disputes (i.e., disputes about which union is the appropriate union to

9

perform a given contract) to final and binding arbitration to the procedures of the jointly administered “Plan for the Settlement of Jurisdictional Disputes in the Construction Industry,” a dispute resolution plan established and administered by The Building and Construction Trades Department, AFL-CIO, and various construction industry employer associations.  If a resolution to a construction-related jurisdictional dispute cannot be obtained through The Building and Construction Trades Department, AFL-CIO, contractors and subcontractors, of whatever tier, Tenant shall agree to submit all such disputes to final and binding arbitration procedures to be administered by the American Arbitration Association (“AAA”) and in conformity with AAA’s Commercial Arbitration Rules, Expedited Procedures, with an arbitrator who is an experienced labor arbitrator and is a member of the National Academy of Arbitration.

C.            This Amendment sets forth the entire agreement between the parties with respect to the matters set forth herein.  There have been no additional oral or written representations or agreements.  Under no circumstances shall Tenant be entitled to any rent abatement, improvement allowance, leasehold improvements, or other work to the Substitution Space, or any similar economic incentives that may have been provided Tenant in connection with entering into the Lease, unless specifically set forth in this Amendment.

D.            Except as herein modified or amended, the provisions, conditions and terms of the Lease shall remain unchanged and in full force and effect.

E.             In the case of any inconsistency between the provisions of the Lease and this Amendment, the provisions of this Amendment shall govern and control.

F.             Submission of this Amendment by Landlord is not an offer to enter into this Amendment but rather is a solicitation for such an offer by Tenant.  Landlord shall not be bound by this Amendment until Landlord has executed and delivered the same to Tenant.

G.            The capitalized terms used in this Amendment shall have the same definitions as set forth in the Lease to the extent that such capitalized terms are defined therein and not redefined in this Amendment.

H.            Tenant hereby represents to Landlord that Tenant has dealt with no broker in connection with this Amendment.  Tenant agrees to indemnify and hold Landlord, its members, principals, beneficiaries, partners, officers, directors, employees, mortgagee(s) and agents, and the respective principals and members of any such agents (collectively, the “Landlord Related Parties”) harmless from all claims of any brokers claiming to have represented Tenant in connection with this Amendment.  Landlord hereby represents to Tenant that Landlord has dealt with no broker in connection with this Amendment.  Landlord agrees to indemnify and hold Tenant, its members, principals, beneficiaries, partners, officers, directors, employees, and agents, and the respective principals and members of any such agents (collectively, the “Tenant Related Parties”) harmless from all claims of any brokers claiming to have represented Landlord in connection with this Amendment.
