                                 PROXY STATEMENT
                       FOR ANNUAL MEETING OF SHAREHOLDERS
                                 AUGUST 21, 2003
                                -----------------

                     SOLICITATION AND REVOCATION OF PROXIES

         The accompanying Proxy is solicited by the Board of Directors of APA
Optics, Inc. (the "Company") in connection with the 2003 Annual Meeting of the
Shareholders of the Company, to be held on August 21, 2003, at 3:30 p.m.
Minneapolis time, at the Four Points Sheraton, 1330 Industrial Boulevard,
Minneapolis, Minnesota 55431 and any adjournments thereof. This Proxy Statement
is first being mailed to shareholders on or about July 17, 2003.

HOW TO VOTE

     o    By signing and returning the enclosed proxy card, you will be giving
          your proxy to our board of directors and authorizing them to vote your
          shares.

HOW YOUR PROXY WILL BE VOTED

     o    Unless revoked, all properly executed Proxies will be voted as
          specified. Proxies that are signed but that lack any specification
          will, subject to the following, be voted FOR all nominees for
          director. If any other matters properly come before the Annual
          Meeting, or if any of the persons named to serve as directors should
          decline or be unable to serve, the persons named in the Proxy will
          vote in accordance with their discretion.

HOW TO REVOKE YOUR PROXY

     o    You have the power to revoke your proxy at any time before the
          convening of the Annual Meeting. Revocations of proxy will be honored
          if received by us, at the Company, addressed to the attention of Anil
          K. Jain, on or before August 20, 2003. In addition, on the day of the
          meeting, prior to the convening thereof, revocations may be delivered
          to the tellers who will be seated at the door of the meeting room.

ABSTENTIONS

     o    If you abstain from voting as to any matter, your shares shall be
          deemed present at the meeting for purposes of determining a quorum and
          for purposes of calculating the vote with respect to such matter, but
          shall not be deemed to have been voted in favor




          of such matter. Abstentions, therefore, as to any proposal will have
          the same effect as votes against such proposal.

BROKER NON-VOTES

     o    If a broker turns in a "non-vote" Proxy, indicating a lack of voting
          instruction by the beneficial holder of the shares and a lack of
          discretionary authority on the part of the broker to vote on a
          particular matter, then the shares covered by such non-vote Proxy will
          be considered present at the meeting for purposes of determining a
          quorum but will not be considered to be represented at the meeting for
          purposes of calculating the vote required for approval of such matter.

COST OF SOLICITATION

     o    We will pay all expenses in connection with the solicitation of
          proxies. Proxies are being solicited primarily by mail, but officers,
          directors, and other employees of the Company may also solicit proxies
          by telephone, telegraph, or personal calls. No extra compensation will
          be paid by us for such solicitation. We may reimburse brokers, banks,
          and other nominees holding shares for others for the cost of
          forwarding proxy materials to, and obtaining proxies from, their
          principals.

                              BOARD RECOMMENDATIONS

         The Board of Directors unanimously recommends that you vote FOR
election of each nominee.

         VOTING RIGHTS

         Only shareholders of record at the close of business on July 7, 2003,
are entitled to notice of and to vote at the meeting or any adjournment thereof.
As of that date, we had issued and outstanding 11,872,331 shares of common
stock. Each holder of record of our common stock is entitled to one vote for
each share registered in the shareholder's name as of the record date. The
Articles of Incorporation of the Company do not grant the shareholders the right
to vote cumulatively for the election of directors. No shareholder will have
appraisal rights or similar dissenter's rights as a result of any matters
expected to be voted on at the meeting.

         The presence in person or by proxy of holders of a majority of the
shares of common stock entitled to vote at the Annual Meeting will constitute a
quorum for the transaction of business.

                            OWNERSHIP OF COMMON STOCK
         The following table shows as of July 7, 2003, the stock ownership of

these committees during fiscal 2003 were as follows:

         AUDIT COMMITTEE. The Audit Committee is responsible for meeting with
the Company's independent public accountants to discuss the annual audit and
related accounting and financial matters. The audit committee held four meetings
in fiscal 2003. The Audit Committee operates under a written charter adopted by
the Board of Directors and the Audit Committee. The role of the Audit Committee
is to assist the Board of Directors in its oversight of the Company's financial
reporting process; management of the Company is responsible for the preparation,
presentation and integrity of the Company's financial statements, the Company's
accounting and financial reporting principles and internal controls and
procedures designed to assure compliance with accounting standards and
applicable laws and regulations. See "RELATIONSHIP WITH INDEPENDENT AUDITORS -
Report of Audit Committee" below, and the Audit Committee Charter filed as
Appendix A to this Proxy Statement.

         COMPENSATION COMMITTEE. The compensation committee develops general
compensation policies and establishes compensation plans and specific
compensation levels for executive officers. The compensation committee met once
during fiscal 2003 to consider the compensation of the executive officers. See
"EXECUTIVE COMPENSATION - Report of Compensation Committee" below.

         COMPENSATION OF DIRECTORS. Each director who is not also an employee of
the Company receives an annual director's fee of $5,000 and $500 for each Board
or committee meeting attended (subject to a maximum of $500 per day). We paid a
total of $25,500 in directors' fees for services rendered during fiscal 2003.

         Under the terms of our Stock Option Plan for Nonemployee Directors,
each director who is not otherwise an employee of the Company receives annually,
on the first business day following the annual shareholders' meeting or, if
earlier, on September 1, an option to purchase 5,000 shares of common stock. The
exercise price for the option equals the fair market value of the stock on the
date of grant. Each option becomes exercisable on the earlier of the date of the
next annual shareholders' meeting or one year from the date of grant and is
exercisable for a period of four years thereafter. During fiscal 2003, options
to purchase 10,000 shares at $2.00 per share and 5,000 shares at $1.55 per share
were awarded to nonemployee directors pursuant to this Plan.

         and an auto allowance.

         CHANGE OF CONTROL ARRANGEMENT. We have an agreement with Anil K. Jain
providing for certain benefits in the event of a change in control of the
Company. If, following a change in control (as defined in the agreement), Dr.
Jain's employment is terminated within 36 months other than for "cause" (as
defined) or as a result of his retirement, disability, or death, or if Dr. Jain
terminates his employment for "good reason" (as defined), he is to receive a
lump sum payment equal to two and one-half times his annualized includable
compensation for the base period (as defined in Section 280G(d) of the Internal
Revenue Code of 1986, as amended). "Good reason" includes certain changes in Dr.
Jain's duties, responsibilities, status, salary, benefits, and other similar
terms of his employment made without his consent. A "change in control" for
purposes of the agreement includes a consolidation or merger of the Company in
which the Company is not the continuing or surviving corporation, any sale,
lease, exchange, or transfer of all or substantially all of the assets of the
Company, approval by the shareholders of any plan or proposal for liquidation or
dissolution of the Company, the acquisition by any person (as such term is used
in Sections 13(d) and 14(d)(2) of the Securities Exchange Act of 1934, as
amended) of beneficial ownership of 30% or more of the Company's outstanding
common stock, or a change in the board of directors of the Company during any
period of two consecutive years such that individuals who at the beginning of
such period constituted the entire Board of Directors cease for any reason to
constitute a majority (with certain exceptions).

         In addition, we have an agreement with Dr. Jain providing that upon the
occurrence of a change in control, in conjunction with a change in Dr. Jain's
current position, other than by voluntary resignation, Dr. Jain will have the
option to request the Company to purchase from him a number of shares of his
common stock equal to up to 4% of the shares of common stock outstanding
immediately prior to the change in control at a price per share equal to the
highest per share price paid in connection with the change in control event or
the highest price paid in the public market within the twelve months preceding
Dr. Jain's exercise of the option. This option is effective for a period of
twelve months after the change in control.

REPORT OF THE COMPENSATION COMMITTEE

         COMPENSATION POLICY. In determining the Company's executive
compensation policy and levels, the compensation committee seeks to attract and
retain qualified executive officers, motivate executive officers to improve the
Company's performance, and reward executive officers for individual
contributions to the achievement of the Company's business objectives. The
committee attempts to achieve these goals by combining annual base salaries with
bonuses based on corporate performance and on the achievement of specified
performance objectives. The compensation committee believes that cash
compensation in the form of salary and bonus provides executives with short-term
rewards for success in operations. The compensation committee also believes that
long-term compensation through the award of stock options encourages growth in
management stock ownership which leads to expansion of management's stake in the
long-term performance and success of the Company.

         BASE SALARY. In determining the base salary of each of the executive
officers, the Company relies on information regarding salaries paid to executive
officers with comparable responsibilities employed by companies with comparable
businesses and also takes into account the Company's cash needs. In fiscal 2003,
the base salary of the executive officers was increased by an average of 2.0%.

         BONUSES. Annual incentives for the Chief Executive Officer and the
other executive officers are intended to reward the attainment of annually
established goals in various areas over which the individual officer has
significant influence or control, including product development, product
manufacturing, sales levels and others. No bonuses were or will be paid to the
executive officers for fiscal 2002 or in fiscal 2003.


                                       8



         STOCK OPTIONS. To date, because the Chief Executive Officer owns a
significant percentage of the Company's outstanding common stock, he has not
been awarded options. Options have been awarded to other management employees.

         COMPENSATION OF CHIEF EXECUTIVE OFFICER. The compensation committee
believes that the compensation of the Chief Executive Officer should reflect the
Company's performance. In fiscal 2003, the annual base salary of the Company's
Chief Executive Officer was increased to $183,600, or by 2%. No bonus was paid
to the Chief Executive Officer for fiscal 2002 or fiscal 2003.

         SECTION 162 LIMITATION. The compensation committee has considered
whether any revisions to the Company's executive compensation policy may be
necessary due to provisions of Section 162 of the Internal Revenue Code, which
limits to $1,000,000 the deductibility of compensation paid to certain
executives. It is the current policy of the compensation committee to maximize,
to the extent reasonably possible, the Company's ability to obtain a corporate
tax deduction for compensation paid to executive officers of the Company to the
extent consistent with the best interest of the Company and its shareholders.

                     CERTAIN RELATIONSHIPS AND TRANSACTIONS

         SUBLEASE FOR COMPANY FACILITY. Effective December 1, 1984, we entered
into a sublease for office and manufacturing space with Jain-Olsen Properties, a
partnership consisting of Anil K. Jain and Kenneth A. Olsen, who are officers,
directors, and principal shareholders of the Company. In fiscal 2000, we entered
into an Amendment and Extension of the Sublease through November 30, 2004.
Certain terms of the sublease are set forth in Note K of Notes to Financial
Statements included in our 2003 Annual Report, which is being distributed with
this Proxy Statement. We made rent and tax payments under the lease of $139,000
and $138,000 to Jain-Olsen Properties during fiscal 2003 and 2002, respectively,
and we are obligated to make payments in fiscal 2004 of $140,000 in rent plus
taxes. The sublease will expire in November 2004. We believe the lease terms are
at least as favorable to us as terms we could have negotiated with an unrelated
third party.




                                       10



         KEY MAN INSURANCE. We maintain key man insurance in the amount of
$2,000,000 on the life of Anil K. Jain and in the amount of $500,000 on the life
of Kenneth A. Olsen, both of whom are directors and officers. Up to $500,000 of
the proceeds of each policy is intended to be used to purchase shares of our
common stock owned by the insured at the request of the personal representative
of the insured's estate. The per share price for the repurchase will be the fair
market value of the common stock as of the date of the event triggering the
repurchase.

         SPLIT DOLLAR INSURANCE. In November 1989, we adopted a split dollar
life insurance plan (the "1989 Plan") for the benefit of Anil K. Jain. Under the
terms of the 1989 Plan, we pay the premiums on a $5 million insurance policy
(the "Policy") on the lives of Dr. Jain and his spouse. The Policy is a whole
life, joint and survivor policy, on which all premiums are paid by us and income
is imputed to Dr. Jain in an amount equal to the term rate for his insurance as
established by the insurer. No premium payments have been made since January
1996.

         The Policy is owned by the Jain Children's Irrevocable Trust dated
November 28, 1989 (the "Trust"). The 1989 Plan is designed so that we will
recover all premium payments and advances made by us on account of the Policy
held by the Trust. Our interest in the premium payments and advances is secured
by a collateral assignment of the Policy. Upon the death of the last to die of
Dr. Jain and his spouse, we will be reimbursed from the insurance proceeds paid
to the Trust in an amount equal to the total premiums and advances made by us.
In the event the trustee of the Trust surrenders the Policy for its cash
surrender value at some date in the future, we will be reimbursed for the
premiums paid on the Policy.



             SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

         Based solely upon a review of Forms 3, 4 and 5 and amendments thereto
furnished to the Company and any written representations that no Forms 5 were
required, the Company believes that all reports required to be filed by its
officers, directors, and greater than 10% beneficial shareholders under Section
16(a) of the Exchange Act were timely filed.

                     RELATIONSHIP WITH INDEPENDENT AUDITORS

CHANGE OF AUDITOR

         On March 8, 2002, the Audit Committee recommended, and the Board of
Directors approved, the appointment of Grant Thornton LLP as our new independent
accountant and auditor, replacing Ernst & Young LLP. The Company did not consult
with Grant Thornton LLP on any matters related to accounting principles or
practices, financial statement disclosures or audit procedures prior to
selecting and appointing Grant Thornton LLP as its auditor.

         Ernst & Young LLP's reports on the Company's financial statements for
the previous fiscal year ended March 31, 2001, did not contain any adverse
disclaimer of opinion and were not qualified as to uncertainty, audit accounting
principles. During the Company's two most recent fiscal years ended March 31,
2001 and the subsequent interim period ended March 2, 2002, (i) there were no
disagreements between the Company and Ernst & Young LLP on any matter of
accounting principle practices, financial statement disclosure or auditing scope
or procedure if not resolved to the satisfaction of Ernst & Young LLP, would
have caused Ernst & Young LLP to reference to the subject matter of the
disagreement in connection with its reports and (ii) there were no "reportable
events," as defined in Item 304(a)(1)(v) of Regulation S-K of the Securities and
Exchange Commission. The decision to replace Ernst & Young LLP was not the
result of any disagreement between the Company and Ernst & Young LLP on any
matter of accounting principle or practice, financial disclosure or audit
procedure.

         Grant Thornton LLP, independent auditors, audited the financial
statements of the Company for the fiscal years ended March 31, 2003 and 2002.
The Company anticipates that Grant Thornton LLP will be retained as the
Company's independent auditors for fiscal 2004. Representatives of Grant
Thornton LLP are expected to be present at the Annual Meeting and will have the
opportunity to make a statement, if they desire to do so, and would be available
to respond to appropriate questions.

REPORT OF AUDIT COMMITTEE

         The Audit Committee of the Board of Directors is comprised of three
nonemployee directors. All members are independent as defined under the rules of
The Nasdaq Stock Market.

         The Audit Committee held three meetings during fiscal 2003. The
meetings were designed to facilitate and encourage communication between the
Audit Committee and the Company's independent auditors, Grant Thornton LLP.

         During these meetings, the Audit Committee reviewed and discussed the
audited financial statements with management and the auditors.

         The discussions with the auditors also included the matters required by
Statement on Auditing Standards No. 61 (Communication with Audit Committees).
The auditors also provided to the Audit Committee the written disclosures and
the letter regarding their



                                       12


independence as required by the Independence Standards Board Standard No. 1.
This information was discussed with the auditors.

         Based on these discussions, the Audit Committee recommended to the
Board of Directors that the audited financial statements for the fiscal year
ended March 31, 2003 be included in the Company's annual report on Form 10-K.

                         Members of the Audit Committee

INDEPENDENT AUDITORS' FEES

         AUDIT SERVICES. The Company paid Grant Thornton LLP related fees of
$36,020 for the fiscal year ended March 31, 2003. These fees were paid for
professional services related to the audit of the financial statements, reviews
of quarterly financial statements included as part of the Company's Form 10-Q
filings for the year and fees related to other miscellaneous regulatory filings.

         The Company paid no fees to Ernst & Young LLP for the fiscal year ended
March 31, 2003.

         INFORMATION AND TECHNOLOGY SERVICES. The Company did not engage Ernst &
Young LLP or Grant Thornton LLP for services related to information technology
during the year ended March 31, 2003.

         OTHER NON-AUDIT SERVICES. For the year ended March 31, 2003, the
Company was not billed by Ernst & Young LLP for any non-audit services. Grant
Thornton LLP billed the Company $4,511 for tax return preparation fees.


                                  OTHER MATTERS

         We are not aware that any matter other than those described in the
Notice of Meeting will be presented for action at the meeting. If, however,
other matters do properly come before the meeting, it is the intention of
Messrs. Jain and Olsen (the persons named as proxies) to vote the proxied shares
in accordance with their best judgment on such matters.

         The Company's 2004 Annual Meeting of Shareholders is expected to be
held on or about August 19, 2004, and proxy materials in connection with that
meeting are expected to be mailed on or about July 10, 2004. In order to be
included in the Company's proxy materials for the 2004



                                       13


Annual Meeting, shareholder proposals prepared in accordance with the proxy
rules must be received by the Company on or before March 25, 2004.

         In addition, pursuant to the Company's Bylaws, a shareholder must give
notice to the Company prior to May 25, 2004 of any nominations for director or
any proposal which such shareholder intends to raise at the 2004 Annual Meeting.
If the Company receives notice of such nomination or proposal on or after that
date, such nomination or proposal will not be considered at the annual meeting.

         Additionally, if the Company receives notice of a shareholder proposal
after June 2, 2004, it will be considered untimely pursuant to SEC Rules 14a-4
and 14a-5(e), and the persons named in the proxies solicited by the Board of
Directors for the 2004 Annual Meeting may exercise discretionary voting power
with respect to the proposal.

APPENDIX A


                                APA OPTICS, INC.



                             AUDIT COMMITTEE CHARTER



Objective
- ---------

The audit committee of the board of directors of APA shall use its best efforts
to ensure the independence of the company's independent accountants, the
integrity of management, and the adequacy of disclosure to the company's
shareholders, potential shareholders, and the investment community.

MEMBERS

The audit committee shall be appointed annually by the board of directors, with
its chairman (if any) to be selected by the committee. The committee shall have
at least three members. Each member must also be a member of the board of
directors. All of the committee members shall be "independent" and no member
shall own or control 20% or more of the company's securities. A director is
"independent" if he/she is an "independent director" as defined in the rules of
the Nasdaq Stock Market, Inc., and any other exchange on which the company's
securities are listed.

In selecting members of the audit committee, the board shall give consideration
to each nominee's capacity to serve, business experience, knowledge of APA
operations, finance, accounting, and auditing, facility in obtaining information
by inquiry, and commitment and available time.

Each member shall have the ability to read and understand fundamental financial
statements, and at least one member shall be an "audit committee financial
expert" as defined in the rules of the Securities and Exchange Commission.

The committee shall annually elect one of its members as chairperson. The
chairperson shall schedule meetings, preside over meetings, and report to the
board.

Vacancies on the committee shall be filled by the board of directors.

Meetings
- --------

The committee shall meet a minimum of 4 times per year and as scheduled by the
committee chairman. A majority of members (at least 2 of 3) shall constitute a
quorum. Each member shall be entitled to one vote. At the request of the
committee, meetings may be held with members of



                                       15


management or the company's internal accounting staff or representatives of the
company's independent accountants or consultants. The committee shall prepare
and preserve written minutes of its meetings. The committee may appoint a
committee member or a non-committee member as secretary. The committee may take
action by conference telephone call, which shall constitute a meeting, or by
written action signed by all members.

The activities and findings of the committee and minutes of committee meetings
shall be made available to each member of the board.

AUTHORITY

The committee shall have unrestricted access to the company's personnel and
records and will be given the resources to discharge its duties. The committee
shall have the authority to engage independent counsel and other advisors, as it
deems necessary, to carry out its duties. The committee may conduct
investigations into significant matters brought to its attention during the
conduct of its duties and may retain persons having special competence as
necessary. The committee shall have the sole authority and responsibility to
select, evaluate, and, where appropriate, replace the outside auditors. The
committee also has the sole authority and responsibility to approve any
significant non-audit relationship with the independent auditors.

Responsibility
- --------------

While the fundamental responsibility for the company's financial statements and
disclosures rests with management and the independent auditor, the audit
committee must review:

     o    major issues regarding accounting principles and financial statement
          presentations, including any significant changes in the company's
          selection or application of accounting principles, and major issues as
          to the adequacy of the company's internal controls and any special
          audit steps adopted in light of material control deficiencies;

     o    analyses prepared by management and/or the independent auditor setting
          forth significant financial reporting issues and judgments made in
          connection with the preparation of the financial statements, including
          analyses of the effects of alternative GAAP methods on the financial
          statements;

     o    the effect of regulatory and accounting initiatives, as well as
          off-balance sheet structures, on the financial statements of the
          company; and

     o    earnings press releases (paying particular attention to any use of
          "pro forma," or "adjusted" non-GAAP, information), as well as
          financial information and earnings guidance provided to analysts and
          rating agencies.

     o    establish procedures for (1) the receipt, retention, and treatment of
          complaints received by the company regarding accounting, internal
          accounting controls, or auditing matters; and (2) the confidential,
          anonymous submission by employees of the company of concerns regarding
          questionable accounting or auditing matters.



                                       16


The audit committee shall have such other responsibilities as may be designated
to it from time to time by the board of directors. In addition, the audit
committee shall annually review and assess the adequacy of its Charter and
recommend to the board of directors any modifications in its duties and
responsibilities.

Operations
- ----------

The audit committee shall:

     o    Assist board oversight of (1) the integrity of the company's financial
          statements, (2) the company's compliance with legal and regulatory
          requirements, (3) the independent auditor's qualifications and
          independence, and (4) the performance of the company's independent
          auditors.

     o    Prepare the report that SEC rules require be included in the company's
          annual proxy statement.

     o    Retain and terminate the company's independent auditors (subject, if
          applicable, to shareholder ratification).

     o    At least annually, obtain and review a report by the independent
          auditor describing: such firm's internal quality-control procedures;
          any material issues raised by the most recent internal quality-control
          review, or peer review, of the firm, or by any inquiry or
          investigation by governmental or professional authorities, within the
          preceding five years, respecting one or more independent audits
          carried out by the firm, and any steps taken to deal with any such
          issues; and (to assess the auditor's independence) all relationships
          between the independent auditor and the company. The audit committee
          should present its conclusions with respect to the independent auditor
          to the full board

     o    Discuss the annual audited financial statements and quarterly
          financial statements with management and the independent auditor,
          including the company's disclosures under "Management's Discussion and
          Analysis of Financial Condition and Results of Operations."

     o    Discuss earnings press releases, as well as financial information and
          earnings guidance provided to analysts and rating agencies. The audit
          committee's responsibility to discuss earnings releases as well as
          financial information and earnings guidance may be done generally
          (i.e., discussion of the types of information to be disclosed and the
          type of presentation to be made). The audit committee need not discuss
          in advance each earnings release or each instance in which the company
          may provide earnings guidance.

     o    As appropriate, obtain advice and assistance from outside legal,
          accounting or other advisors.

     o    Discuss policies with respect to risk assessment and risk management.
          The audit committee should analyze the company's major financial risk
          exposures and discuss with



                                       17


          management the steps management has taken to monitor and control such
          exposures. The audit committee is not required to be the sole body
          responsible for risk assessment and management.

     o    Periodically meet separately with management, with personnel
          responsible for the internal preparation of financial reports and
          records, and with independent auditors.

     o    Review with the independent auditor any audit problems or difficulties
          and management's response. Among the items the audit committee may
          want to review with the auditor are: any accounting adjustments that
          were noted or proposed by the auditor but were "passed" (as immaterial
          or otherwise); any communications between the audit team and the audit
          firm's national office respecting auditing or accounting issues
          presented by the engagement; and any "management" or "internal
          control" letter issued, or proposed to be issued, by the audit firm to
          the company. The review should also include discussion of the
          responsibilities, budget and staffing of the company's internal
          financial functions.

     o    Set clear hiring policies for employees or former employees of the
          independent auditors which shall comply in all respects with the rules
          of the Securities and Exchange Commission concerning independence of
          auditors and similar rules of any stock exchange on which the
          company's securities are listed.

     o    Report regularly to the board of directors. The audit committee should
          review with the full board any issues that arise with respect to the
          quality or integrity of the company's financial statements, the
          company's compliance with legal or regulatory requirements, the
          performance and independence of the company's independent auditors, or
          the performance of the internal financial accounting.

     o    Annually evaluate the performance of the audit committee.

     o    Review, discuss and report to the board of directors concerning
          changes, if any, made or proposed by the government, accounting
          profession, or the company relating to accounting principles and their
          applications that could materially affect the company.

     o    Review, discuss and report to the board of directors concerning
          significant issues reviewed by legal counsel concerning litigation,
          contingencies, claims, or assessments.

     o    Review, discuss and report to the board of directors concerning
          significant adjustments proposed by the independent accountants.

     o    Inquire of the independent accountants as to whether there have been
          any disagreements with management which, if not satisfactorily
          resolved, would have caused them to issue a nonstandard report on the
          company's financial statements.

     o    Review unusual reporting issues prior to the issuance of any press
          release on financial results.

     o    Advise the independent accountants and members of the internal
          accounting staff that they may communicate directly with any member of
          the committee on a confidential basis.



                                       18

          members of the company's financial staff to discuss pertinent matters.

     o    Review with the chief financial officer the activities, organizational
          structure, and qualifications of the internal financial staff.

     o    Inquire of the chief financial officer and independent accountants the
          extent to which their planned audit scope can be relied on to detect
          material weaknesses in internal controls or the occurrence of
          fraudulent financial reporting.

Corporate Compliance
- --------------------

The committee shall conduct such review as it deems necessary to ensure that the
company is maintaining effective controls against employee conflict of interest
and fraud and is in reasonable compliance with related laws. Without limitation

          code of conduct and the Foreign Corrupt Practices Act.

          expenses and purchases.

          developments that may affect the company.

     o    Review any legal matters that could have a significant impact on the
          company's financial statements.

     o    If necessary, institute special investigations and, if appropriate,
          hire special counsel or experts to assist.


                                       19


Qualified Legal Compliance Committee
- ------------------------------------

The committee shall be the company's "qualified legal compliance committee" as
defined in the rules of the Securities and Exchange Commission. In this
capacity, the committee shall:

     o    Adopt written procedures for the confidential receipt, retention and
          consideration of any report of a material violation of federal
          securities laws, breach of fiduciary duty or similar violations by the
          company or any officer, director, employee or agent of the company.

     o    Inform the company's chief legal officer and chief executive officer
          of any report of evidence of a material violation.

     o    Determine whether an investigation is necessary regarding any report
          of evidence of a material violation by the company, its officers,
          directors, employees or agents and, if it determines an investigation
          is necessary or appropriate:

          o    Notify the full board of directors;

          o    Initiate an investigation, which may be conducted either by the
               chief legal officer (or the equivalent thereof) or by outside
               attorneys; and

          o    Retain such additional expert personnel as the committee deems
               necessary.

     o    At the conclusion of any such investigation:

          o    Recommend, by majority vote, that the company implement an
               appropriate response to evidence of a material violation;

          o    Inform the chief legal officer and the chief executive officer
               (or the equivalents thereof) and the board of directors of the
               results of any such investigation and the appropriate remedial
               measures to be adopted; and

          o    Acting by majority vote, take all other appropriate action,
               including the notification of the Securities and Exchange
               Commission in the event that the company fails in any material
               respect to implement an appropriate response that the qualified
               legal compliance committee has recommended.

Miscellaneous
- -------------

As to other related matters, without limitation and as it deems appropriate, the
committee shall:

          financial and accounting personnel and any relevant recommendations
          that the independent accountants may have, including those in their
          "Report to Management."



                                       20




     o    Review the extent of nonaudit services provided by the independent
          accountants in relation to the objectivity needed in the audit.

     o    Evaluate the cooperation received by the independent accountants
          during their audit examination, including the access to all requested
          records, data, and information and elicit the comments of management
          regarding the responsiveness of the independent accountants to the
          company's needs.

     o    Request from outside auditors a formal written statement regarding all
          relationships between the outside auditors and the company.

     o    Maintain an active dialogue with the outside auditors regarding any
          undisclosed relations or services that could affect the objectivity
          and independence of the outside auditors.

     o    Take, or recommend that the board of directors take, appropriate
          action to oversee the outside auditors' independence.
