corporate authority to enter into and perform its obligations under this
Agreement and to issue the Investment Shares, (ii) the execution, issuance and
delivery of this Agreement and the Investment Shares by the Company and the

authorized by all necessary corporate action and no further consent or
authorization of the Company or its Board of Directors or stockholders is
required, and (iii) this Agreement and the Investment Shares have been duly
executed and delivered by the Company and at the Closing shall constitute valid
and binding obligations of the Company enforceable against the Company in
accordance with their terms, except as such enforceability may be limited by
applicable bankruptcy, insolvency, or similar laws relating to, or affecting
generally the enforcement of, creditors' rights and remedies or by other
equitable principles of general application.

the SEC Documents complied in all material respects with the requirements of the
Exchange Act, and rules and regulations of the SEC promulgated thereunder and
the SEC Documents did not contain any untrue statement of a material fact or

order to make the statements therein, in light of the circumstances under which
they were made, not misleading. The financial statements of the Company included

imposition by the Company of any liens, charges, claims or other encumbrances
upon the Investment Shares or any of the assets of the Company, or (ii) entitle
the holders of Outstanding Common Stock to preemptive or other rights to

authorization or order of, or make any filing or registration with, any court or
governmental agency in order for it to execute, deliver or perform any of its
obligations under this Agreement or issue and sell the Investment Shares in

substantive rights and defenses by reason of such failure. In connection with
any Claim as to which both the Indemnifying Party and the Indemnified Party are
parties, the Indemnifying Party shall be entitled to assume the defense thereof.
Notwithstanding the assumption of the defense of any Claim by the Indemnifying
Party, the Indemnified Party shall have the right to employ separate legal
counsel and to participate in the defense of such Claim, and the Indemnifying
Party shall bear the reasonable fees, out-of-pocket costs and expenses of such
separate legal counsel to the Indemnified Party if (and only if): (x) the
Indemnifying Party shall have agreed to pay such fees, out-of-pocket costs and
expenses, (y) the Indemnified Party and the Indemnifying Party reasonably shall
have concluded that representation of the Indemnified Party and the Indemnifying
Party by the same legal counsel would not be appropriate due to actual or, as
reasonably determined by legal counsel to the Indemnified Party, potentially
differing interests between such parties in the conduct of the defense of such
Claim, or if there may be legal defenses available to the Indemnified Party that
are in addition to or disparate from those available to the Indemnifying Party,
or (z) the Indemnifying Party shall have failed to employ legal counsel
reasonably satisfactory to the Indemnified Party within a reasonable period of
time after notice of the commencement of such Claim. If the Indemnified Party
employs separate legal counsel in circumstances other than as described in
clauses (x),

(y) or (z) above, the fees, costs and expenses of such legal counsel shall be
borne exclusively by the Indemnified Party. Except as provided above, the
Indemnifying Party shall not, in connection with any Claim in the same
jurisdiction, be liable for the fees and expenses of more than one firm of legal
counsel for the Indemnified Party (together with appropriate local counsel). The
Indemnifying Party shall not, without the prior written consent of the
Indemnified Party (which consent shall not unreasonably be withheld), settle or
compromise any Claim or consent to the entry of any judgment that does not
include an unconditional release of the Indemnified Party from all liabilities
with respect to such Claim or judgment.

Section 7.4. Direct Claims. In the event one party hereunder should have a claim
for indemnification that does not involve a claim or demand being asserted by a
third party, the Indemnified Party promptly shall deliver notice of such claim
to the Indemnifying Party. If the Indemnified Party disputes the claim, such
dispute shall be resolved by mutual agreement of the Indemnified Party and the
Indemnifying Party or by binding arbitration conducted in accordance with the
procedures and rules of the American Arbitration Association as set forth in
Article X. Judgment upon any award rendered by any arbitrators may be entered in
any court having competent jurisdiction thereof.

Section 8.1. Due Diligence Review. Subject to Section 8.2, the Company shall
make available for inspection and review by the Investor, and advisors to and
representatives of the Investor (who may or may not be affiliated with the
Investor and who are reasonably acceptable to the Company), all SEC Documents
and other filings with the SEC, and all other publicly available corporate
documents and properties of the Company as may be reasonably necessary for the
purpose of such review, and cause the Company's officers, directors and
employees to supply all such publicly available information reasonably requested
by the Investor or any such representative or advisor.

Section 8.2. Non-Disclosure of Non-Public Information. (a) The Company shall not
disclose material non-public information to the Investor, or advisors to or
representatives of the Investor, unless prior to disclosure of such information
the Company identifies such information as being non-public information and
provides the Investor, such advisors and representatives with the opportunity to
accept or refuse to accept such non-public information for review. The Company
may, as a condition to disclosing any non-public information hereunder, require
the Investor's advisors and representatives to enter into a confidentiality
agreement in form reasonably satisfactory to the Company and the Investor.

            (b) Nothing herein shall require the Company to disclose material
non-public information to the Investor or its advisors or representatives, and
the Company represents that it does not disseminate material non-public
information to any investors who purchase stock in the Company in a public
offering, to money managers or to securities analysts.

Exhibit 10.31

Description of Performance Based Compensation Plan Bonus Criteria for Fiscal Year 2005

The following executive officers of ESS Technology, Inc. (the “Company”) are participants in the
Company’s Performance Based Compensation Plan (the “Plan”) for fiscal year 2005: Fred S.L. Chan,
Chairman; Robert L. Blair, President and Chief Executive Officer; and James B. Boyd, Chief Financial Officer and Senior Vice
President. On March 31, 2005, the Compensation Committee of the Board
of Directors of the Company (the “Compensation Committee”) approved performance criteria applicable
to the payment of bonuses for fiscal year 2005 under the Plan.

The fiscal year 2005 performance criteria approved by the Compensation Committee focus primarily on
strategic corporate objectives that are designed to elicit performance critical to the short-term and long-term
success of the Company. In particular, the approved performance criteria include goals related to
the design and implementation of market and product strategies (including DVD, cameraphone and
analog products), plans and roadmaps, internal processes, and corporate compliance and operational
objectives. Each executive’s primary areas of responsibility vary within the performance criteria
and not every executive is allocated responsibility for each criteria. Accordingly, the
Compensation Committee has determined the applicability of each criteria and the weighing of the
respective criteria for each executive.

Achievement of all of the performance objectives could result in maximum bonuses under the Plan of
200% of their annual base salary for each of Messrs. Chan and Blair, and 100% of his annual base
salary for Mr. Boyd. The earned bonus for each executive shall be subject to downward (but not
upward) discretionary adjustments, if any, as determined by the Compensation Committee. The
Compensation Committee will determine whether the performance objectives were reached after the end
of the Company’s fiscal year 2005, and any bonus payments will be made pursuant to the Plan no
later than March 15, 2006.
