            7.4 ENTIRE AGREEMENT. This Parent Voting Agreement, the Proxy and
any other documents delivered by the parties in connection herewith constitute
the entire agreement between the parties with respect to the subject matter
hereof and thereof and supersede all prior agreements and understandings between

any Person (other than the Company and its successors and assigns) any rights or

or was otherwise breached. Stockholder agrees that, in the event of any breach
or threatened breach by Stockholder of any covenant or obligation contained in
this Parent Voting Agreement or in the Proxy, the Company shall be entitled (in
addition to any other remedy that may be available to it, including monetary
damages) to seek and obtain (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. Stockholder further
agrees that neither the Company nor any other Person shall be required to
obtain, furnish or post any bond or similar instrument in connection with or as
a condition to obtaining any remedy referred to in this Section 7.6, and
Stockholder irrevocably waives any right he may have to require the obtaining,
furnishing or posting of any such bond or similar instrument.

            7.7 NON-EXCLUSIVITY. The rights and remedies of the Company under
this Parent Voting 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 the Company
under this Parent Voting Agreement, and the obligations and liabilities of
Stockholder under this Parent Voting Agreement, are in addition to their
respective rights, remedies, obligations and liabilities under common law
requirements and under all applicable statutes, rules and regulations. Nothing
in this Parent Voting Agreement shall limit any of Stockholder's obligations, or
the rights or remedies of the Company, under any Affiliate Agreement between the
Company and Stockholder; and nothing in any such Affiliate Agreement shall limit
any of Stockholder's obligations, or any of the rights or remedies of the
Company, under this Parent Voting Agreement.

            7.8 GOVERNING LAW; VENUE.

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

                (b) Any legal action or other legal proceeding relating to this
Parent Voting Agreement or the Proxy or the enforcement of any provision of this
Parent Voting Agreement or the Proxy may be brought or otherwise commenced in

   7

agrees that service of any process, summons, notice or document by U.S. mail
addressed to him at the address set forth in Section 7.2 shall constitute
effective service of such process, summons, notice or document for purposes of
any such legal proceeding; (iii) agrees that each state and federal court
located in the County of Santa Clara, California, shall be deemed to be a
convenient forum; and (iv) agrees not to assert (by way of motion, as a defense
or otherwise), in any such legal proceeding commenced in any state or federal
court located in the County of Santa Clara, California, any claim that
Stockholder is not subject personally to the jurisdiction of such court, that
such legal proceeding has been brought in an inconvenient forum, that the venue
of such proceeding is improper or that this Parent Voting Agreement or the
subject matter of this Parent Voting Agreement may not be enforced in or by such
court. Nothing contained in this Section 7.8(b) shall be deemed to limit or
otherwise affect the right of the Company to commence any legal proceeding or
otherwise proceed against Stockholder in any other forum or jurisdiction.

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

            7.9 COUNTERPARTS. This Parent Voting Agreement may be executed by
the parties 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.

            7.10 CAPTIONS. The captions contained in this Parent Voting
Agreement are for convenience of reference only, shall not be deemed to be a
part of this Parent Voting Agreement and shall not be referred to in connection
with the construction or interpretation of this Parent Voting Agreement.

            7.11 ATTORNEYS' FEES. If any legal action or other legal proceeding
relating to this Parent Voting Agreement or the enforcement of any provision of
this Parent Voting Agreement is brought by one party against the other party,
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).

            7.12 WAIVER. No failure on the part of the Company to exercise any
power, right, privilege or remedy under this Parent Voting Agreement, and no
delay on the part of the Company in exercising any power, right, privilege or
remedy under this Parent Voting 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. The Company shall not
be deemed to have waived any claim available to the Company arising out of this
Parent Voting Agreement, or any power, right, privilege or remedy of the Company
under this Parent Voting 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 the Company; and any such waiver shall not
be applicable or have any effect except in the specific instance in which it is
given.

            7.13 CONSTRUCTION.

Voting Agreement to "Sections" and "Exhibits" are intended to refer to Sections

Reorganization Agreement or any actions contemplated thereby, however called, or
in connection with any solicitation of written consents from stockholders of
Parent, in favor of the approval of the issuance of shares of Parent Common
Stock in the Merger, in favor of the election of Lev J. Leytes to the Board of
Directors of Parent, and in favor of each of the other actions contemplated by
the Reorganization Agreement.

        The undersigned may vote the Shares on all other matters.

        This proxy shall be binding upon the heirs, estate, executors, personal
representatives, successors and assigns of the undersigned (including any
transferee of any of the Shares).

        If any provision of this proxy or any part of any such provision is held
under any circumstances to be invalid or unenforceable in any jurisdiction, then
(a) such provision or part thereof shall, with respect to such circumstances and
in such jurisdiction, be deemed amended to conform to applicable laws so as to
be valid and enforceable to the fullest possible extent, (b) the invalidity or
unenforceability of such provision or part thereof under such circumstances and
in such jurisdiction shall not affect the validity or enforceability of such
provision or part thereof under any other circumstances or in any other
jurisdiction, and (c) the invalidity or unenforceability of such provision or
part thereof shall not affect the validity or enforceability of the remainder of
such provision or the validity or enforceability of any other provision of this
proxy. Each provision of this proxy is separable from every other provision of
