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.

	 	 	SECTION 6. Representations and Warranties of Stockholders

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

partnership duly organized, validly existing and in good standing under the laws of the

6.4 Accuracy of Representations. The representations and warranties contained in this

	 	 	SECTION 7. Additional Covenants of Stockholders

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.

contemplated by this Agreement shall be paid by the party incurring such costs and expenses.

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. Subject to the preceding sentence, this Agreement shall be binding upon Stockholder
and Stockholder’s successors and assigns, and shall inure to the benefit of Parent and its
permitted successors and assigns. Without limiting any of the restrictions set forth in this
Agreement, this Agreement shall be binding upon any Person to whom any Subject Shares are
transferred. 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). In any action
between the parties arising out of or relating to this Agreement or any of the transactions
contemplated by this Agreement each of the parties irrevocably and unconditionally consents and
submits to the jurisdiction and venue of the state and federal courts located in the State of
California.

(b) EACH STOCKHOLDER IRREVOCABLY WAIVES THE RIGHT TO A JURY TRIAL IN CONNECTION WITH ANY LEGAL
PROCEEDING RELATING TO THIS AGREEMENT OR THE ENFORCEMENT OF ANY PROVISION OF THIS AGREEMENT.

8.9 Counterparts; Exchanges by Electronic Transmission. This Agreement may be executed in
separate counterparts, each of which when so executed and delivered shall be an original, but all
such counterparts shall together constitute one and the same instrument. 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.

8.10 Headings. The headings contained in this Agreement are for convenience of reference
only, shall not be deemed to be a part of this Agreement and shall not be referred to in connection
with the construction or interpretation of this Agreement.

8.11 Attorneys’ Fees. If any legal action or other legal proceeding relating to this
Agreement or the enforcement of any provision of this Agreement is brought against any party to
this Agreement, the prevailing party shall be entitled to recover reasonable attorneys’ fees, costs
and disbursements (in addition to any other relief to which the prevailing party may be entitled).

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.

8.13 Fiduciary Duty as Director. Parent acknowledges and agrees that each Stockholder’s
obligations hereunder are solely in its capacity as a stockholder of the Company, and that none of
the provisions herein set forth shall be deemed to restrict or limit any fiduciary duty any
directors, officers or employees of the undersigned may have as a member of the board of directors
of the Company resulting from any circumstances other than as a Stockholder of the Company.

8.14 Construction.

(a) For purposes of this Agreement, whenever the context requires: the singular number shall
include the plural, and vice versa; the masculine gender shall include the feminine and neuter
genders; the feminine gender shall include the masculine and neuter genders; and the neuter gender
shall include masculine and feminine genders.

(b) The parties agree that any rule of construction to the effect that ambiguities are to be
resolved against the drafting party shall not be applied in the construction or interpretation of
this Agreement.

(c) As used in this Agreement, the words “include” and “including,” and variations thereof,
shall not be deemed to be terms of limitation, but rather shall be deemed to be followed by the
words “without limitation.”

(d) Except as otherwise indicated, all references in this Agreement to “Sections” and
“Exhibits” are intended to refer to Sections of this Agreement and Exhibits to this Agreement.
