Each Stockholder agrees that, during the period from the date of this Agreement through the Expiration Date, such Stockholder shall not, directly or indirectly, and such Stockholder shall instruct such Stockholder’s Representatives to not, directly or indirectly: (a) solicit, knowingly facilitate or knowingly encourage the initiation of any inquiry, proposal or offer from any Person (other than Parent or Parent’s Representatives) relating to a possible Acquisition Transaction; (b) participate in any discussions or negotiations or enter into any agreement with, or provide any non-public information to, any Person (other than Parent or Parent’s Representatives) relating to or in connection with a possible Acquisition Transaction; or (c) consider, entertain or accept any proposal or offer from any Person (other than Parent or Parent’s Representatives acting on behalf of Parent) relating to a possible Acquisition Transaction.

Nothing contained in this Section 5 or Section 4.4 of the Merger Agreement shall prohibit such Stockholder or its Representatives from having discussions with any potential joint venture partner or otherwise considering any strategic acquisition so long as (x) the potential joint venture or acquisition transaction does not contemplate the sale or issuance of any securities of any Acquired Company (unless otherwise disclosed to Parent prior to the date hereof) and would be intended primarily to address the needs of the Acquired Companies to find alternative sources of production of wafers for customers of the Acquired Companies during periods where the Acquired Companies lack the manufacturing capacity to fulfill their customers’ orders or forecasted orders for wafers, and (y) the Company does not enter into any letter of intent or other binding agreement with respect to any of the foregoing without the prior written consent of Parent, not to be unreasonably withheld.

Each Stockholder hereby represents and warrants (severally but not jointly) to Parent as follows:

If such Stockholder is a corporation, then such Stockholder is duly incorporated, validly existing and in good standing under the laws of the jurisdiction in which it was incorporated.

6.4 Accuracy of Representations. The representations and warranties contained in this Agreement are accurate in all respects as of the date of this Agreement, and will be accurate in all respects at all times through and including the Expiration Date as if made as of any such time or date.

Each Stockholder covenants (severally and not jointly) that:

7.1 Stockholder Information. Parent and Merger Sub may publish and disclose in the Proxy Statement such Stockholder’s identity and ownership of shares of Company Capital Stock and the nature of such Stockholder’s commitments, arrangements and understandings under this Agreement.

7.2 Public Announcements. Except as required by applicable law, such Stockholder shall not issue any press release or make any public statement regarding the Merger Agreement, the Merger or any of the other Contemplated Transactions without the prior written consent of Parent.

7.3 Parent Trust Account. Each Stockholder agrees that it has read a copy of Parent’s prospectus dated March 15, 2006 and filed with the Securities and Exchange Commission (the “Prospectus”). Each Stockholder understands that Parent is a blank check company formed for the purpose of consummating a “business combination” (as described in the Prospectus), must complete such business combination within 18 months (or 24 months if a letter of intent, agreement in principle or definitive agreement has been executed within 18 months) from the date of the consummation of the offering described in the Prospectus, has established a trust account at Lehman Brothers, maintained by Continental Stock Transfer & Trust Company acting as trustee, initially in an amount of $164,308,004 after the exercise of the underwriters’ over-allotment option for the benefit of its public stockholders (the “Trust Account”), and does not have access to the funds in such Trust Account except under the circumstances set forth in the Prospectus. Each Stockholder, on its behalf and on behalf of its affiliates that it has the power to bind (such Stockholder and its affiliates that such Stockholder has the power to bind being referred to as the “Stockholder Claimants”): (a) agrees that neither it nor any of its Stockholder Claimants has any right, title, interest or claim of any kind in or to (i) any assets in the Trust Account, (ii) any assets of Parent to the extent such right, title, interest or claim would impair the amounts in the Trust Account or (iii) any assets distributed from the Trust Account to the public stockholders (each such right, title, interest or claim a “Claim”); (b) unless and until Parent completes the Merger or another Business Combination (as defined in Parent’s certificate of incorporation as of the date of this Agreement), hereby waives any Claim that it or any of its Stockholder Claimants may have in the future as a result of, or arising out of, the Merger Agreement or the Ancillary Agreements; and (c) agrees that neither it nor any of its Stockholder Claimants will seek recourse against the Trust Account or the public stockholders of Parent (in their capacity as stockholders of Parent or as recipients of liquidating distributions from Parent) for any reason whatsoever. Further, each Stockholder acknowledges that such Stockholder has read Section 1542 of the Civil Code of the State of California, which states in full:

“A general release does not extend to claims which the creditor does not know or suspect to exist in his or her favor at the time of executing the release, which if known by him or her must have materially affected his or her settlement with the debtor.”

Each Stockholder hereby waives any right that it or any of its Stockholder Claimants have or may have under Section 1542 (or any similar provision of the laws of any other jurisdiction) to the full extent that such Stockholder may lawfully waive such rights pertaining to this waiver of Claims and generally affirms that such Stockholder is releasing, on behalf of itself and its Stockholder Claimants, all known and unknown Claims.

Without limiting the foregoing, each Stockholder hereby acknowledges and agrees that the Trust Account is not a party to the Merger Agreement and shall have no liability pursuant hereto. Notwithstanding the forgoing, no provision contained herein shall limit the right of a Stockholder or its Stockholder Claimants to make a claim against such monies to the extent such monies are released from the Trust Account to Parent upon the consummation of the Merger.

7.4 Merger Agreement; Appointment of Stockholders’ Representative. Each Stockholder hereby agrees to be bound by the terms of Sections 9 and 10.1 of the Merger Agreement as if such Stockholder was a party to the Merger Agreement. Each Stockholder hereby agrees to and acknowledges the appointment of T.C. Group L.L.C., as such Stockholder’s agent and true and lawful attorney-in-fact to act on such Stockholder’s behalf in accordance with Section 10.1 of the Merger Agreement.

7.5 Further Assurances. From time to time and without additional consideration, each Stockholder shall (at such Stockholder’s sole expense) execute and deliver, or cause to be executed and delivered, such additional transfers, assignments, endorsements, proxies, Consents and other instruments, and shall (at such Stockholder’s sole expense) take such further actions, as Parent may reasonably request for the purpose of carrying out and furthering the intent of this Agreement.

8.3 Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If the final judgment of a court of competent jurisdiction declares that any term or provision hereof is invalid or unenforceable, the parties hereto agree that the court making such determination shall have the power to limit the term or provision, to delete specific words or phrases, or to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be enforceable as so modified. In the event such court does not exercise the power granted to it in the prior sentence, the parties hereto agree to replace such invalid or unenforceable term or provision with a valid and enforceable term or provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable term or provision.

8.4 Entire Agreement. This Agreement constitutes the entire agreement between the parties with respect to the subject matter hereof and supersedes all prior agreements and understandings between the parties with respect thereto. No addition to or modification of any provision of this Agreement shall be binding upon any party hereto unless made in writing and signed by all parties.

8.5 Assignment; Binding Effect. Except as provided herein, neither this Agreement nor any of the interests or obligations hereunder may be assigned or delegated by any party to this Agreement, and any attempted or purported assignment or delegation of any of such interests or obligations shall be void.

Nothing in this Agreement is intended to confer on any Person (other than Parent and its permitted successors and assigns) any rights or remedies of any nature.

8.6 Specific Performance. The parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with its specific terms or were otherwise breached. Each Stockholder agrees that, in the event of any breach or threatened breach by such Stockholder of any covenant or obligation contained in this Agreement, Parent shall be entitled (in addition to any other remedy that may be available to it, including monetary damages) to seek: (a) a decree or order of specific performance to enforce the observance and performance of such covenant or obligation; and (b) an injunction restraining such breach or threatened breach.

8.7 Non-Exclusivity. The rights and remedies of Parent under this Agreement are not exclusive of or limited by any other rights or remedies which it may have, whether at law, in equity, by contract or otherwise, all of which shall be cumulative (and not alternative). Without limiting the generality of the foregoing, the rights and remedies of Parent under this Agreement, and the obligations and liabilities of each Stockholder under this Agreement, are in addition to their respective rights, remedies, obligations and liabilities under common law requirements and under all applicable statutes, rules and regulations.

8.8 Governing Law; Jurisdiction; Waiver of Jury Trial.

(a) This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware (without giving effect to principles of conflicts of laws).

The exchange of a fully executed Agreement (in counterparts or otherwise) by facsimile transmission or other electronic transmission shall be sufficient to bind the parties to the terms and conditions of this Agreement.

8.12 Waiver. No failure on the part of Parent to exercise any power, right, privilege or remedy under this Agreement, and no delay on the part of Parent in exercising any power, right, privilege or remedy under this Agreement, shall operate as a waiver of such power, right, privilege or remedy; and no single or partial exercise of any such power, right, privilege or remedy shall preclude any other or further exercise thereof or of any other power, right, privilege or remedy. Parent shall not be deemed to have waived any claim available to Parent arising out of this Agreement, or any power, right, privilege or remedy of Parent under this Agreement, unless the waiver of such claim, power, right, privilege or remedy is expressly set forth in a written instrument duly executed and delivered on behalf of Parent; and any such waiver shall not be applicable or have any effect except in the specific instance in which it is given.
