D. Capitalized terms used herein and not otherwise defined herein shall have the same meanings as defined in the Prime Lease.

AGREEMENTS:

For good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged and for the mutual covenants contained herein, the parties agree as follows:

1. Term. Sublandlord hereby leases to Subtenant, and Subtenant hereby leases from Sublandlord, the Subleased Premises, for a “Term” commencing upon the later of (i) delivery of the Premises with Sublandlord’s Work, as hereinafter defined, substantially complete, as certified by Sublandlord; and (ii) the date this Sublease has been fully executed by Sublandlord and Subtenant and the Prime Landlord has consented to this Sublease (the “Commencement Date”), and expiring on March 31, 2008 (the “Initial Expiration Date”).

2. Tenancy at Will. Following the Initial Expiration Date, this Sublease shall remain in full force and effect, but shall be converted into a tenancy-at-will on a month-to-month basis for the period (the “At-Will Period”) commencing on April 1, 2008 and expiring on December 31, 2008 (the “Prime Expiration Date”). During the At-Will Period, this Sublease may be terminated by either Subtenant or Sublandlord upon sixty (60) days’ prior written notice to the other party hereto; provided, however, that Sublandlord may terminate this Sublease during the At-Will Period only in the event that Sublandlord and Prime Landlord agree, at Prime Landlord’s request, to an early termination of the Prime Lease. Such notice may be given prior to April 1, 2008, and the tenancy-at-will may be thereby terminated within the first sixty (60) days thereafter, but in no event prior to March 31, 2008. On the Prime Expiration Date, such tenancy-at-will shall automatically terminate without any requirement of notice from either party. Any period during which such tenancy-at-will exists shall be governed by the terms of this Sublease. The “Expiration Date” shall be the later of (i) April 1, 2008 or (ii) such later date before the Prime Expiration Date on which the At-Will Period is terminated as provided in this Section 2.

3. Condition of the Subleased Premises. The Subleased Premises are leased to Subtenant in their “as is” condition as of the date hereof, subject to the work to be performed by Sublandlord, as set forth in Exhibit B attached hereto (“Sublandlord’s Work”). Sublandlord makes no representations, warranties or promises, except as otherwise provided in Exhibit B, Section 30 and this Section 3, with respect to the Subleased Premises, the condition of any equipment therein or the suitability of the Sublease Premises for the uses contemplated by this Sublease. Subtenant agrees to accept possession of the Subleased Premises on the Commencement Date “as is,” in their same condition on the date hereof, subject to the performance by Sublandlord of Sublandlord’s Work.

4. Fixtures; Laboratory Equipment; Furniture. To the extent that there are any fixtures or equipment attached to the Subleased Premises, the same may be used by Subtenant during the Term of this Sublease, and shall remain with the Subleased Premises at the end of the Term. To the extent that any personal property is in the Subleased Premises as of the date of this Sublease, Subtenant accepts possession of all such personal property, without warranty or representation as to the condition thereof, or its fitness for any particular purpose, and such personal property shall be deemed transferred to Subtenant as of the Commencement Date, and Subtenant shall remove the same from the Subleased Premises by the Expiration Date or earlier date of termination of this Sublease. Subtenant shall insure such personal property for its full replacement value during the Term.

5. Subtenant’s Work. Subject to Sublandlord’s prior written consent and approval, which shall not be unreasonably withheld, conditioned or delayed, and Prime Landlord’s prior written consent and approval in accordance with the Prime Lease, Subtenant shall have the right to construct, at Subtenant’s sole cost and expense, alterations to the Subleased Premises to accommodate Subtenant’s occupancy thereof. All alterations shall be performed in accordance with the terms of the Prime Lease. Subtenant shall be solely responsible for removing any alterations installed by Subtenant upon the expiration or termination of this Sublease, to the extent that such removal is required by the Prime Lease. Sublandlord shall permit such reasonable access to the Subleased Premises after the execution of this Sublease and before the Commencement Date as Subtenant may require to construct permitted alterations in the Subleased Premises, provided that the same do not interfere with the performance of Sublandlord’s Work.

6. Rent. The annual base rent per year, drawn on a U.S. bank, payable in advance in equal monthly installments, commencing on the Commencement Date, and thereafter on the first day of each calendar month of the Term in advance, prorated for any partial month at the beginning or end of the Term, shall be One Million Four Hundred Fifty-Eight Thousand Seven Hundred Dollars ($1,458,700.00) annually, or One Hundred Twenty-One Thousand Five Hundred Fifty-Eight and 33/100 Dollars ($121,558.33) monthly. The Rent is intended to be gross rent and includes, without limitation, the following: (i) all charges for utilities furnished to the Subleased Premises, except as set forth in Section 7 below; and (ii) all Additional Rent due under the Prime Lease with respect to the Subleased Premises including, without limitation, Taxes and Operating Expenses (except any Additional Rent occasioned by the default of Subtenant hereunder).

Rent and all other charges due hereunder shall be payable without set-off, offset, deduction or counterclaim at Sublandlord’s address set forth below or at such other place as may be set forth by notice from Sublandlord to Subtenant. Any installment of rent due or accruing hereunder and any other sum, whether termed rent or otherwise, and payable hereunder by Subtenant to Sublandlord, not paid within five (5) business days after written notice that such payment is overdue, shall bear interest from the due date at a rate equal to the prime rate published by the Wall Street Journal from time to time plus three percent (3%).

7. Services. The Subleased Premises shall have available hot water, cold water, tempered water, compressed air, standby power and ventilation, and the removal of lab waste from the Subleased Premises. From and after the Commencement Date, Subtenant shall be solely responsible for their operation, including all utility costs associated therewith and governmental permits required therefor. Subtenant agrees to perform the obligations set forth on Exhibit B with respect to the equipment servicing the Subleased Premises, as described therein.

8. Security System. The Subleased Premises currently contains security card readers and security panels dedicated to the Subleased Premises, which equipment Sublandlord shall leave in place and permit Subtenant to use during the Term, provided Subtenant shall contract directly for any services necessary to operate such facilities. Subtenant shall provide, at its sole cost and expense, any additional security equipment or services that it requires, subject to Sections 4 and 5 of this Sublease and the terms of the Prime Lease.

9. Lab Systems. Subtenant shall have the right during the Term to use the Reverse Osmosis System (“RO System”) and pH neutralization system located at the Building (the “pH System,” and collectively, the “Lab Systems”), as set forth in Exhibit B hereto. Subtenant shall be responsible during the Term, at Subtenant’s sole expense, for all maintenance and repairs to the Lab Systems, except as provided herein. Subtenant shall promptly apply for, obtain and maintain in good standing all governmental permits and approvals required for the operation of the Lab Systems, at Subtenant’s sole expense, except as provided herein.

In the event that Sublandlord occupies any space in the Building during the Term, Sublandlord and Subtenant shall each have a non-exclusive right to use the Lab Systems during such occupancy (the “Shared Use Period”), and each party shall permit such reasonable access by the other party as is necessary for the reasonable use, maintenance and repair of the Lab Systems, provided Subtenant shall comply with Sublandlord’s reasonable rules and regulations regarding the use and operation of the Lab Systems. During the Shared Use Period, Sublandlord shall be responsible, at its sole cost and expense, for all maintenance and repairs to the Lab Systems, and Subtenant shall pay to Sublandlord as Additional Rent Subtenant’s proportionate share of the costs of maintenance and repair to the Lab Systems, which proportionate share shall be fifty percent (50%). During the Shared Use Period, Sublandlord shall apply for and obtain governmental permits and approvals for the operation of the pH System (“Permits”). In the event Sublandlord obtains such Permits, Subtenant shall terminate and abandon any Permits that it has obtained relating to the pH System, and Subtenant’s use of the pH System shall thereafter be subject to Permits obtained by Sublandlord, and Subtenant shall not take any action that would violate the terms and provisions of such Permits.

10. Maintenance and Repairs. Except as otherwise expressly provided herein, Subtenant shall be responsible, commencing on the Commencement Date, for all maintenance and repairs to equipment solely serving the Subleased Premises and located within the Subleased Premises. Subtenant shall also be responsible during the Term, at Subtenant’s sole expense, for the maintenance and repair of the generator located in the parking lot adjacent to the Subleased Premises. Notwithstanding the foregoing, Subtenant shall be responsible for the Subtenant’s Proportionate Share of all costs related to any shared building systems repaired by the Sublandlord or Landlord, excluding any capital expenditures. “Subtenant’s Proportionate Share” shall be a fraction, the numerator of which shall be the number of net rentable square feet within the Subleased Premises, and the denominator of which shall be the number of net rentable square feet within the Building.

11. Parking. Subtenant shall have the right to use during the Term one hundred eight (108) parking spaces in the Building parking lot leased by Sublandlord from Prime Landlord pursuant to Section 9 of the Extension Agreement. Prior to the Initial Expiration Date, Subtenant may use such parking spaces at no additional cost.

Subtenant agrees to perform, fulfill, and observe all of the covenants, agreements, obligations, conditions, representations, warranties, terms and provisions imposed upon Sublandlord as Tenant of the Subleased Premises under the Prime Lease as applicable to the Subleased Premises arising from and after the Commencement Date, except for rent allocable to the Subleased Premises, which shall be governed by this Sublease. Subtenant agrees to indemnify and hold Sublandlord harmless from and against any and all claims, liabilities, losses and damages of any kind whatsoever (including, without limitation, reasonable attorneys’ fees and expenses) which Sublandlord may incur by reason of Subtenant’s failure to perform, fulfill or observe any of the covenants or agreements set forth herein or the applicable provisions set forth in the Prime Lease.

The indemnification obligations of each party shall survive the termination or expiration of this Sublease.

16. Termination. This Sublease shall terminate upon the termination of the Prime Lease for any reason whatsoever, without any liability therefor on the part of Sublandlord to Subtenant (except as expressly set forth in Section 15 above), with the same force and effect as if the date of such termination had been provided expressly in this Sublease as the Expiration Date. Sublandlord covenants and agrees that prior to the Initial Expiration Date Sublandlord will not voluntarily surrender or terminate the Prime Lease except in the event of a taking or casualty in accordance with the Prime Lease, nor shall it agree to modify or amend the Prime Lease in any way that will reduce the rights or increase the obligations of Subtenant under this Sublease in any material respect.

17. Compliance with Law. Subtenant shall comply with all statutes, ordinances, rules, orders, regulations or requirements relating to its specific use of the Subleased Premises, including environmental regulations applicable to its particular manner of use of the Subleased Premises, as opposed to the Permitted Uses under the Prime Lease, and in no event shall Sublessee ever be responsible for making any capital expenditures hereunder, and Subtenant shall obtain and comply with all government permits and approvals required in connection with Subtenant’s research and other activities in the Subleased Premises. Notwithstanding anything to the contrary contained herein, in no event shall Subtenant be liable for any existing violations of applicable law with respect to the Subleased Premises existing on the Commencement Date of the Sublease. Subtenant agrees to provide reasonable cooperation to Sublandlord and Prime Landlord to secure any necessary permits or approvals related to the operation of the Building.

20. Holding Over. If Subtenant remains on the Subleased Premises after the Expiration Date or after earlier termination of this Sublease, then such holding over shall not be deemed to extend or renew the term of this Sublease or to create any tenancy at will (except as expressly provided herein), but such holding over shall be as a tenancy-at-sufferance only subject to all the terms and provisions of this Sublease; provided, however, Subtenant shall be liable for two hundred percent (200%) of all rent and other charges related to occupancy of the Subleased Premises. In addition, Subtenant shall indemnify and hold harmless Sublandlord from and against all liability, damages, losses and claims (including, without limitation, reasonable attorneys’ fees and expenses) incurred by Sublandlord in connection with the holding over of Subtenant including, without limitation, any liability of Sublandlord to Prime Landlord. Notwithstanding the foregoing, Sublandlord may, at its option, regain possession of the Subleased Premises or any part thereof by any and all means available to Sublandlord under this Sublease, the Prime Lease, or at law. The provisions of this Section 20 shall be superseded by any separate agreement between Prime Landlord and Subtenant under which Subtenant retains occupancy of the Subleased Premises from and after the Prime Expiration Date, provided that Sublandlord shall have no liability with respect to the Subleased Premises from and after the Prime Expiration Date.

22. Assignment and Subletting. Subtenant shall not assign or sublease this Sublease without the prior written consent of Sublandlord, which consent may be withheld in Sublandlord’s sole discretion, and the prior written consent of Prime Landlord, as provided in the Prime Lease. Notwithstanding anything to the contrary contained herein, Sublandlord’s consent shall not be required for a proposed assignment of this Sublease or subletting of the Subleased Premises to an entity (1) that controls, is controlled by or is under common control with Subtenant, or (2) provided that the net worth of the successor entity is no less than the net worth of Subtenant as of the date of this Sublease, that (i) acquires all or substantially all of Subtenant’s assets, stock or membership interests or (ii) that merges or consolidates with Subtenant.
