                                 PROXY STATEMENT
                                 ---------------

                         2004 ANNUAL MEETING OF SHAREHOLDERS

      This  Proxy  Statement  is  being  furnished  to  the  Shareholders   (the
"Shareholders") of Aehr Test Systems, a California  corporation (the "Company"),
in connection with the solicitation of proxies by the Board of Directors for use
at the Annual Meeting of Shareholders  (the "Annual  Meeting") of the Company to
be held on October 19, 2004 and at any adjournments thereof.

      At the Annual Meeting, the Shareholders will be asked:

      1. To elect five directors.

      2. To ratify the selection of PricewaterhouseCoopers  LLP as the Company's
         independent  registered  public  accounting  firm  for  the fiscal year
         ending May 31, 2005.

      3. To transact such other  business as may properly come before the Annual
         Meeting or any adjournments of the Annual Meeting.

      The Board of Directors  has fixed  the close of business  on  September 9,
2004 as the record date for the  determination  of the  holders of Common  Stock
entitled to notice of and to vote at the Annual Meeting.  Each such  Shareholder
will be entitled  to one vote for each share of Common  Stock  ("Common  Share")
held on all matters to come before the Annual  Meeting and may vote in person or
by proxy authorized in writing.

      This Proxy  Statement and the  accompanying  form of proxy are first being
sent to holders of the Common Shares on or about September 27, 2004.


                               THE ANNUAL MEETING

Date, Time and Place

      The Annual  Meeting  will be held on October 19, 2004 at 4:00 p.m.,  local
time, at 400 Kato Terrace, Fremont, California 94539.

General

      The Company's  principal  office is located at 400 Kato Terrace,  Fremont,
California 94539 and its telephone number is (510) 623-9400.

Record Date and Shares Entitled to Vote

      Shareholders of record at the close of business on September 9, 2004  (the
"Record Date") are entitled to notice of and to vote at the Annual  Meeting.  As
of the Record Date, there were 7,393,719 Common Shares  outstanding and entitled
to vote.

Revocability of Proxies

      Any proxy given pursuant to this solicitation may be revoked by the person
giving it at any time  before  its use by  delivering  to  the Secretary of  the
Company a written notice  of  revocation  or a duly  executed  proxy  bearing  a
later date or by attending the meeting and voting in person.

Voting and Proxy Solicitation

      Each shareholder  voting for the election of directors may cumulate his or
her  votes,  giving  one  candidate  a number  of votes  equal to the  number of
directors to be elected  multiplied by the number of shares that the shareholder
is  entitled  to  vote,  or  distributing  the  shareholder's  votes on the same
principle among as many candidates as the  shareholder  chooses.  No shareholder
shall be entitled to cumulate  votes for any  candidate  unless the  candidate's
name has  been  properly  placed  in  nomination  prior  to the  voting  and the
shareholder, or any other shareholder,  has given notice at the meeting prior to
the voting of the intention to cumulate votes.  On all other matters, each share
has one vote.

                                       1


      Proxies are being solicited by the Company.  The cost of this solicitation
will be borne by the  Company.  The Company may  reimburse  brokerage  firms and
other persons  representing  beneficial  owners of shares for their  expenses in
forwarding solicitation material to such beneficial owners.  Proxies may also be
solicited  by  certain  of  the  Company's  directors,   officers,  and  regular
employees, without additional compensation, personally or by telephone, telegram
or facsimile.

Quorum; Abstentions; Broker Non-Votes

      The required  quorum for the transaction of business at the Annual Meeting
is a majority of the shares of Common Stock issued and outstanding on the Record
Date.  Votes cast by proxy or  in person at the Annual Meeting will be tabulated
by  the  Inspector of Elections,  appointed for the meeting,  who will determine
whether  or not a quorum is present.  If the shares present,  in person  and  by
proxy, do not constitute the  required quorum, the meeting may by adjourned to a
subsequent  date for  the purposes of obtaining a quorum.  Shares that are voted
"FOR,"  "AGAINST"  or "WITHHELD  FROM" a matter are treated as being  present at
the  meeting for  purposes of  establishing a quorum and  shares that are  voted
"FOR," "AGAINST" or "ABSTAIN" are  also  treated as shares entitled to vote (the
"Votes Cast") at the Annual Meeting  with respect to  such matter.

      While there is no definitive statutory or case law authority in California
as to the proper treatment of abstentions, the Company believes that abstentions
should be counted for purposes of  determining  both (i) the presence or absence
of a quorum for the  transaction  of business and (ii) the total number of Votes
Cast with respect to a proposal  (other than the election of directors).  In the
absence of controlling  precedent to the contrary,  the Company intends to treat
abstentions in this manner.  Accordingly,  abstentions will have the same effect
as a vote against the proposal.

      Broker  non-votes (i.e. votes from shares of record by brokers as to which
the beneficial owners have no voting instructions)  will be counted for purposes
of  determining  the  presence or  absence of  a quorum for  the transaction  of
business, but will not be counted for  purposes  of  determining  the  number of
Votes Cast with  respect  to the proposal on which the broker has  expressly not
voted.  Thus,  a  broker non-vote will make a quorum  more readily  but will not
otherwise  affect the outcome of  the  voting on  a proposal.  With respect to a
proposal  that  requires  a  majority  of  the  outstanding  shares  (such as an
amendment to the articles of incorporation),  however, a broker non-vote has the
same affect as a vote against the proposal.

Deadline for Receipt of Shareholder Proposals for 2005 Annual Meeting

      Shareholders are entitled to present proposals for action at a forthcoming
meeting if they comply with the  requirements of the proxy rules  promulgated by
the Securities and Exchange Commission ("SEC"). Proposals of shareholders of the
Company intended to be presented for  consideration at the Company's 2005 Annual
Meeting of  Shareholders  must be  received by the Company no later than May 22,
2005,  in order that they may be  included  in the proxy  statement  and form of
proxy related to that meeting.

     On October 23, 1996,  the Board of Directors approved the 1996 Stock Option
Plan  (the "Stock Plan").  The  Stock Plan  provides  for the  granting  of non-
qualified stock options or incentive stock options to employees and  consultants
at  the fair market value of the Company's common stock as of the date of grant.
Options  granted under the  Stock Plan  generally vest  at a rate  of 1/48th per
month, however,  the vesting schedule can change on a grant-by-grant basis.  The
Stock Plan provides that  vested  options  may be exercised  for 3 months  after
termination of employment and for 12 months after termination of employment as a
result of  death or disability.   The Company may select alternative  periods of
time  for exercise upon termination of service.   The Stock Plan permits options
to be exercised with cash, check,  certain other shares of the Company's  common
stock  or  consideration  received by  the  Company under a  "cashless exercise"
program.  In the event that the Company merges with or into another corporation,
or sell substantially all of the Company's assets,  the Stock Plan provides that
each  outstanding option will be  assumed or  substituted for  by the  successor
corporation. If such substitution or assumption does not occur, each option will
fully vest  and  become  exercisable.  As of May 31, 2004,  there were 1,721,869
shares  of  Common  Stock  reserved  under  the  Stock Plan  and  626,141 shares
remaining for future issuance.

     On June 9, 1997,  the Board of Directors  adopted  the  1997 Employee Stock
Purchase Plan (the "ESPP").  The ESPP has consecutive,  overlapping, twenty-four
month  offering periods.  Each twenty-four month  offering period  includes four
six month purchase periods.  The offering periods  generally begin  on the first
trading day on or  after April 1 and October 1 each year,  except that the first
such  offering period commenced with the effectiveness  of the Company's initial
public offering and  ended on the last trading day on or  before March 31, 1999.
Shares are purchased  through  employee payroll  deductions  at exercise  prices
equal to  85% of the  lesser of the  fair market value  of  the Company's Common
Stock at  either  the  first day of an  offering period or  the last day of  the
purchase period.  If a participant's rights to purchase stock under all employee
stock purchase plans of the Company accrue at a rate which exceeds $25,000 worth
of stock for a calendar year,  such participant may not be  granted an option to
purchase stock under the ESPP.   The maximum number of shares a  participant may
purchase  during a single purchase period  is 3,000 shares.  As of May 31, 2004,
there were 400,000 shares of  Common Stock  reserved  under the ESPP and 117,834
shares remaining for future issuance.

Unless otherwise instructed, the proxy holders will vote the proxies received by

should additional persons be nominated at the meeting,  the proxy holders intend
to vote  all  proxies  received  by them in such a  manner  as will  assure  the
election of as many nominees  listed below as possible (or, if new nominees have
been  designated  by the Board of  Directors,  in such a manner as to elect such
nominees)  and the specific  nominees to be voted for will be  determined by the
proxy  holders.  The Company is not aware of any reason that any nominee will be
unable or will  decline to serve as a  director.  There are no  arrangements  or
understandings  between any director or  executive  officer and any other person
pursuant  to which he is or was to be  selected  as a director or officer of the

Board Meetings and Corporate Governance

Board Meetings and Committees

        The Board of Directors  held a total of five (5) meetings and  acted two
(2) times by  unanimous  written  consent  during the fiscal  year ended May 31,
2004.  No  incumbent  director  during his period of service in such fiscal year
attended  fewer  than  75% of the  aggregate  of all  meetings  of the  Board of
Directors and the committees of the Board upon which such director served.

        The  Board of Directors has two committees,  the Audit Committee and the
Compensation Committee.   The Company does not have a  nominating committee or a
committee performing the functions of a nominating committee.

        The Audit Committee  of the Board of Directors is  comprised entirely of
independent directors,  as defined in the  National  Association  of  Securities
Dealers, Inc.'s listing standards, for which information regarding the functions
performed by  the  Committee,  its membership,  and the number of  meetings held
during the  fiscal year,  is set forth  in the  "Report of the Audit Committee,"
included in this Proxy Statement.   The Audit Committee is governed by a written
charter approved by the Board of Directors.   A copy of this charter is included
in  this  Proxy  Statement  as  Appendix A.   The  Audit  Committee  consists of
directors  Messrs. Anderson,  Elder  and  Patel.   The  Board  of  Directors has
determined  that  Mr. Anderson is an audit committee financial expert as defined
by  Item 401(h)  of  Regulation S-K of the  Securities Exchange Act of 1934,  as
amended (the "Exchange Act").

        The Compensation  Committee of the Board of Directors currently consists
of Messrs.  Elder and Rosati.  The  Compensation  Committee held one (1) meeting
during  fiscal year 2004.  The  Compensation  Committee  reviews and advises the
Board of Directors  regarding  all forms of  compensation  to be provided to the
officers, employees, directors and consultants of the Company.

Consideration of Director Nominees

        All members of the  Board of Directors  participate in the consideration
of director nominees. The Company is also in the process of forming a nominating
committee for future consideration of director nominees.

Stockholder Recommendations

        The policy of the Board of Directors  is to consider properly  submitted
shareholder  recommendations  for  candidates  for  membership  on the  Board as
described  below under  "Identifying and Evaluating Nominees for Directors."  In
evaluating such  recommendations,  the  Board of  Directors  seeks to  achieve a
balance of knowledge,  experience and capability on the Board and to address the
membership  criteria  set forth  under  "Director Qualifications"  below.   Any
shareholder   recommendations  proposed  for  consideration  by  the   Board  of
Directors  should  include  the  candidate's  name and  qualifications for Board
membership and should be addressed to:

Aehr Test Systems
400 Kato Terrace
Fremont, CA 94539
Attn:  Secretary

        In addition,  procedures for stockholder direct  nomination of directors
are discussed under "Deadline for Receipt of Stockholder Proposals" above.

Director Qualifications

        Members of the  Board should have the  highest professional and personal
ethics  and values,  consistent  with the  Company's  Code of Conduct and Ethics
adopted       by     the     Board    in       an      action     by     written

                                       7


consent dated September 24, 2004.   They  should  have broad  experience  at the
policy-making  level  in  business.   They  should  be  committed  to  enhancing
shareholder value and should have sufficient time to carry out their duties  and
to provide insight and practical wisdom based on  experience.   Their service on
other boards  of  public companies  should  be limited  to a number that permits
them, given their individual circumstances,  to perform responsibly all director
duties.  Each director must represent the interests of all shareholders.

Identifying and Evaluating Nominees for Directors

        The Board of Directors utilizes a variety of methods for identifying and
evaluating nominees for director.  The Board of Directors periodically  assesses
the  appropriate size of the Board,  and whether any vacancies on the  Board are
expected  due to  retirement or  otherwise.  In  the  event that  vacancies  are
anticipated,  or  otherwise  arise,  the  Board of Directors  considers  various
potential candidates for director.   Candidates may come to the attention of the
Board of Directors  through  current  Board members,  professional search firms,
shareholders or other persons.  These candidates  are evaluated  at  regular  or
special meetings of the Board of Directors,  and may be considered at  any point
during the year.  As described above,  the Board of Directors considers properly
submitted  shareholder recommendations for candidates for the Board.   Following
verification  of  the  shareholder status of persons proposing  candidates,  any
recommendations  are aggregated and  considered by the  Board of Directors  at a
regularly scheduled meeting prior to the issuance of the proxy statement for our
annual meeting.   If any materials are provided by a  shareholder  in connection
with the recommendation of a director candidate, such materials are forwarded to
the  Board  of  Directors.  The  Board of Directors  may also  review  materials
provided  by  professional search firms  or other parties  in connection  with a
candidate  who  is  not  recommended  by  a  shareholder.   In  evaluating  such
recommendations, the Board of Directors seeks to achieve a balance of knowledge,
experience and capability on the Board.

        The  Board  of  Directors  has  determined  that  each  of  its  current
directors, except for Rhea J. Posedel, the Company's Chief Executive Officer, is
independent  within  the  meaning  of  the  Nasdaq  Stock  Market, Inc. director
independence standards, as currently in effect.

Annual Meeting Attendance

        Although the Company does not have a formal policy  regarding attendance
by  members of the  Board at the  Company's  annual  meetings  of  shareholders,
directors   are   encouraged  to  attend  annual   meetings  of  the   Company's
shareholders.  All directors attended the 2003 annual meeting of shareholders.

Code of Conduct and Ethics

        The Board of Directors has adopted a Code of Conduct and Ethics  for all
directors,  officers  and  employees of the Company,  which  includes the  Chief
Executive Officer,  Chief Financial Officer  and any other  principal accounting
officer.  The Company will provide a copy of the Code of Conduct and Ethics upon

                        REPORT OF THE AUDIT COMMITTEE(1)

        The Audit Committee  of the Board of Directors of the  Company serves as
the representative of the Board for general oversight of the Company's financial
accounting and reporting system of internal  control,  audit process and process
for  monitoring  compliance  with laws and  regulations.  The  Audit  Committee,

                                       8


consisting of  Messrs. Patel,  Anderson  and  Elder,  held  five (5) meetings in
fiscal year 2004.  Each member is an independent director in accordance with the
Nasdaq  National  Market  Audit  Committee  requirements.   The Audit  Committee
evaluates the scope of the  annual audit,  reviews audit results,  consults with
management and the Company's independent registered public accounting firm prior
to the presentation of financial statements to stockholders and, as appropriate,
initiates inquiries into aspects of the Company's financial affairs.

        The Company's  management has primary  responsibility  for preparing the
Company's  financial  statements  and  for  the  Company's  financial  reporting
process.   The   Company's   independent   registered  public  accounting  firm,
PricewaterhouseCoopers LLP ("PwC"), is responsible for expressing  an opinion on
the  conformity  of  the  Company's  audited  financial  statements to generally
accepted accounting  principles.  The Audit Committee has reviewed and discussed
with  management  the  audited  financial  statements for the year ended May 31,
2004.   PwC,  the  Company's  independent registered public accounting firm  for
fiscal year 2004,  issued  their unqualified report dated August 30, 2004 on the
Company's consolidated financial statements.

        The Audit Committee has also discussed with PwC the matters  required to
be discussed by AICPA  Statement on Auditing  Standards  No. 61,  "Communication
with Audit  Committees."  The Audit  Committee  has also  received  the  written
disclosures  and the letter from PwC required by  Independence  Standards  Board
Standard  No. 1,  "Independence  Discussions  with  Audit  Committees,"  and has
conducted  a  discussion  with  PwC  relative  to its  independence.  The  Audit
Committee  has  considered  whether  PwC's  provision of  non-audit  services is
compatible  with its  independence.  The Audit  Committee has an Audit Committee
Charter.  A copy of the charter is attached in Appendix A.

        Based on the  reviews  and  discussions  referred  to  above,  the Audit
Committee  recommended  to the Board of  Directors of Aehr Test Systems that the
Company's audited financial statements for the fiscal year ended May 31, 2004 be
included in the Annual Report on Form 10-K.

incorporation language contained in such filing.

Director Compensation

        Rhea J.  Posedel,  the only  inside  director of the  Company,  does not
receive  any cash  compensation  for his  services  as a member  of the Board of
Directors. Each outside director receives (1) an annual retainer of $10,000, (2)
$1,250  for each  regular  board  meeting  he  attends,  and (3)  $750 for  each
committee  meeting he attends if not held in  conjunction  with a regular  board
meeting,  in  addition to being  reimbursed  for  certain  expenses  incurred in
attending  Board  and  committee  meetings.   Prior to  each  annual meeting  of
shareholders,  each  outside director  may elect to receive  an additional stock
option grant  in lieu of  any  cash  payments throughout  the  year.   An inside
director is a director who is a regular  employee  of the  Company,  whereas  an
outside  director  is not an employee of the Company.  Directors are eligible to
participate  in the  Company's  stock  option  plans.   In fiscal 2002,  outside
directors Robert Anderson,  William Elder,  Mukesh Patel and  Mario Rosati  were
each  granted  options to  purchase 5,000 shares at $3.85 per share.   In fiscal
2003,  outside directors  Robert Anderson, William Elder, Mukesh Patel and Mario
Rosati were each granted options to purchase 5,000 shares at $2.70 per share. In
fiscal 2004, outside directors Robert Anderson, William Elder, Mukesh Patel  and
Mario Rosati  were  each  granted options to purchase  5,000 shares at $3.79 per

                                       9


Additionally, Robert Anderson and Mukesh Patel were each granted 9,499 shares at
$3.79 per share pursuant to an  agreement to  take these shares of stock in lieu
of cash payments throughout the fiscal year.

        The Company has agreed to indemnify each director against certain claims
and expenses for which the director might be held liable in connection with past
or future service on the Board.  In addition, the Company maintains an insurance
policy insuring its officers and directors against such liabilities.

Vote Required

        The five nominees  receiving the highest number of affirmative  votes of
the shares  present or  represented and  entitled to be voted for them  shall be
elected as directors.  Votes withheld from any director are counted for purposes
of  determining  the  presence  or  absence of a quorum for the  transaction  of
business,  but have no other  legal  effect in the  election of  directors under
California law.  See "Quorum; Abstentions; Broker Non-Votes."

(1)   The options were granted under the 1996 Stock Option Plan and  vested over

      year ended May 31,  2004 to  employees  and  consultants  to the  Company,

(3)   The  exercise  price per share of each option was equal to the fair market
      value of the Common Stock on the date of grant as  determined by the Board
      of  Directors,  except the  exercise  price of the options  granted to Mr.
      Posedel was equal to 110% of the fair market  value of the Common Stock on
      the date of the grant.

(4)   This  column sets forth  hypothetical  gains or "option  spreads"  for the
      options at the end of their  respective seven-year terms, as calculated in
      accordance with the rules of the SEC. Each gain is based on an arbitrarily
      assumed  annualized  rate of compound  appreciation of the market price at
      the date of grant of  5% and  10%  annually from  the date the option  was
      granted  to  the  end  of  the  option  term.  The  5% and  10%  rates  of
      appreciation are specified  by the  rules  of the SEC and do not represent
      the  Company's  estimate or projection of future Common Stock prices.  The
      Company does not  necessarily  agree that  this method  properly values an
      option.   Actual gains,  if any, on option exercises are  dependent on the
      future  performance of the  Company's  Common  Stock  and  overall  market
      conditions and the timing of option exercises, if any.

      The following table provides  information  concerning  option exercises by
the persons named in the Summary Compensation Table during the fiscal year ended
May 31, 2004 and the value of unexercised options at such date.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

General

      In its ordinary course of business,  the Company enters into  transactions
with certain of its directors and officers.  The Company believes that each such
transaction  has been on terms no less favorable for the Company than could have
been obtained in a transaction with an independent third party.

Legal Counsel

      During fiscal 2004, Mario M. Rosati, a member of the Board of Directors of
the  Company,  was also a member of the law firm of Wilson  Sonsini  Goodrich  &
Rosati, Professional Corporation  ("WSGR").   The Company  retained  WSGR as its
legal  counsel  during the fiscal year.  The Company plans to retain WSGR as its
legal counsel again during fiscal 2005.

Change of Control Severance Agreement

      On January 24, 2001,  the Company entered into Change of Control Severance
Agreements with Mr. Carl N. Buck, Mr. David S. Hendrickson,  Mr. Gary L. Larson
and  Mr. Rhea J. Posedel pursuant to which those executives would be entitled to
a payment  in the event of a  termination  of employment  for specified  reasons
following  a change of control  of the Company.   For this purpose,  a change of
control of the Company means a merger or consolidation of the Company, a sale by
the  Company of  all  or  substantially  all of its assets,  the  acquisition of
beneficial ownership of a  majority of the outstanding voting securities  of the
Company by any person or a change in the composition of the Board as a result of
which  fewer  than  a   majority  of  the  directors  are  incumbent  directors.
Termination of employment for purposes of these agreements means  a discharge of
the  executive  by  the  Company,  other  than  for  specified  causes including
dishonesty,  conviction of a felony,  misconduct or  wrongful acts.  Termination
also  includes  resignation following the occurrence of an adverse change in the
executive's  position,  duties,  compensation or  work conditions.   The amounts
payable  under the  agreements  will  change  from  year to year  based  on  the
executive's compensation. In the event of a termination in fiscal 2005 following
a change of control,  the  amounts payable to  Messrs. Buck, Hendrickson, Larson
and  Posedel  would  be  approximately $79,000, $101,000, $138,000 and $238,000,
respectively.

Compensation Committee Interlocks and Insider Participation

      The  Compensation  Committee  consists  of Messrs.  Elder and  Rosati.  No
interlocking  relationship  exists between the Company's  Board of Directors and
Compensation  Committee and the board of directors or compensation  committee of
any other company.

                      REPORT OF THE COMPENSATION COMMITTEE
                            OF THE BOARD OF DIRECTORS

      Notwithstanding anything to the contrary set forth in any of the Company's
previous filings under the Securities  Exchange Act of 1933, as amended,  or the
Securities  Act of 1934,  as amended,  that might  incorporate  future  filings,
including this Proxy  Statement,  in whole or in part, the following  report and
the  Performance  Graph shall not be  incorporated  by  reference  into any such
filings and  such information shall be entitled to the benefits provided in Item
306(c) and (d) of Regulation S-K and Item 7(d)(3)(v) of Schedule 14A.

General

      The objectives  of  the overall  executive  compensation  program  are  to
attract,  retain,  motivate and  reward Company executives while  aligning their
compensation with the  achievements of key business  objectives, maximization of
shareholder value and optimal satisfaction of customers.

      The Compensation Committee is responsible for:

      1. Determining the specific executive  compensation  methods to be used by
         the Company and the participants in each of those specific programs;

      2. Determining the evaluation  criteria and timeliness to be used in those
         programs;

                                       13


      3. Determining  the  processes  that  will  be  followed  in  the  ongoing
         administration of the programs; and

      4. Determining their role in the administration of the programs.

      All of the actions take the form of  recommendations  to the full Board of
Directors  where final  approval,  rejection  or  redirection  will  occur.  The
Compensation   Committee  is  responsible  for  administering  the  compensation
programs for all Company officers.  The Compensation Committee has delegated the
responsibility of administering the compensation  programs for all other Company
employees to the Company's officers.

Compensation Vehicles

      Currently, the Company uses the following executive compensation vehicles:

      o  Cash-based programs:  Base salary,  Annual Incentive Bonus Plan, Annual
         Profit Sharing Plan, and a Sales Incentive Commission Plan; and

      o  Equity-based  programs:  1996  Incentive  Stock Option  Plan,  the 1997
         Employee Stock Purchase Plan and the Employee Stock Bonus Plan.

      These  programs apply to  all executive level  positions,  except for  the
Sales  Incentive  Commission  Plan,  which  only  includes  executives  directly
responsible  for  sales activities.  Periodically,  but at least  once  near the
close of each fiscal year, the Compensation Committee reviews the existing plans
and recommends those that should be used for the subsequent year.

      The criteria for determining the appropriate salary level, bonus and stock
option grants for each of the executive officers include (a) Company performance
as a whole, (b) business unit performance (where appropriate) and (c) individual
performance objectives.  Company performance and business  unit  performance are
measured against both strategic and financial goals. Examples of these goals are
to obtain:  operating profit,  revenue growth,  timely new product introduction,
and shareholder value (usually measured by the Company stock price).  Individual
performance  is  measured to  specific objectives  relevant to  the individual's
position and a specific time frame.

      These criteria are usually related to a fiscal year time period,  but may,
in some cases, be measured over a shorter or longer time frame.

      The processes  used by the  Compensation  Committee  include the following
steps:

      1. The Compensation  Committee periodically receives information comparing
         the  Company's  pay levels to other  companies  in similar  industries,
         other  leading  companies  (regardless  of industry)  and  competitors.
         Primarily national and regional compensation surveys are used.

      2. At or  near  the  start  of each  evaluation  cycle,  the  Compensation
         Committee meets with the Chief Executive  Officer to review,  revise as
         needed,  and  agree on the  performance  objectives  set for the  other
         executives.   The  Chief Executive Officer  and  Compensation Committee
         jointly set the Company objectives to be used.   The business  unit and
         individual  objectives  are formulated  jointly by the Chief  Executive
         Officer  and the specific individual.  The Compensation Committee also,
         with the  Chief Executive Officer,  jointly  establishes and  agrees on
         their respective performance objectives.

      3. Throughout the  performance  cycle review,  feedback is provided by the
         Chief Executive Officer, the Compensation  Committee and full Board, as
         appropriate.

      4. At the  end of the  performance  cycle,  the  Chief  Executive  Officer
         evaluates  each  other  executive's  relative  success  in  meeting the
         performance goals. The Chief Executive Officer makes recommendations on
         salary, bonus and stock options, utilizing the comparative results as a
         factor.  Also included in the decision criteria are subjective  factors
         such as teamwork,  leadership  contributions and ongoing changes in the
         business    climate.    The  Chief   Executive   Officer  reviews   the
         recommendations and obtains Compensation Committee approval.

      5. The final  evaluations  and  compensation  decisions are discussed with
         each  executive  by  the  Chief   Executive   Officer  or  Compensation
         Committee, as appropriate.

Compensation of the Chief Executive Officer

      The Compensation  Committee  used the same  compensation policy  described
above  for  all executive officers to  determine  the compensation  for  Rhea J.
Posedel,   the    Company's     Chief    Executive     Officer,    in     fiscal

                                       14


year 2004.   In setting both the cash-based and the equity-based elements of Mr.
Posedel's  compensation,  the  Compensation Committee  considered  the company's
performance, competitive forces taking into account Mr. Posedel's experience and
knowledge, and Mr. Posedel's leadership in achieving our long-term goals. During
fiscal year 2004,  he received a stock option grant  under our 1996 Stock Option
Plan for 25,000 shares.   These options vest over four years.   The Compensation
Committee  believes  Mr. Posedel's  fiscal  year  2004  compensation  was  fair,
relative to the  Company's performance and  Mr. Posedel's individual performance
and leadership, and it rewards him for this performance and will serve to retain
him as a key employee.

Policy on Deductibility of Compensation

      We are required  to disclose our  policy  regarding  qualifying  executive
compensation for deductibility under Section 162(m) of the Internal Revenue Code
of 1986, as amended,  which provides that,  for purposes of the  regular  income
tax,  the otherwise allowable deduction  for  compensation  paid or accrued with
respect to  the  executive  officers of a  publicly-held company,  which is  not
performance-based  compensation is limited  to no more than $1 million per year.
It is not expected  that the compensation to be paid to our  executive  officers
for fiscal 2004 will  exceed  the $1 million limit per officer;  however, to the
extent  such compensation  to be paid to such  executive officers exceeds the $1
million  limit per officer,  such excess  will be  treated as  performance-based
compensation.

      The Compensation  Committee feels that the  compensation  vehicles used by
the  company,  generally  administered  through the  process as outlined  above,
provide a fair and balanced executive compensation program related to the proper
business issues. In addition, it should be noted that compensation vehicles will
be  reviewed  and,  as  appropriate,  revised in order to attract and retain new
executives in addition to rewarding performance on the job.

      The  following  graph shows a comparison of  total shareholder  return for
holders of the Company's Common Stock for the  last five fiscal years and ending
May 31, 2004,  compared  with  The  Nasdaq  Stock  Market (U.S.) Index  and  the
Philadelphia Semiconductor Index.   The graph assumes that $100 was invested  in
the Company's Common Stock,  in  the  Nasdaq  Stock  Market (U.S.) Index and the
Philadelphia Semiconductor Index  on May 31, 1999,  and that  all dividends were
reinvested.   The Company believes that while total shareholder return can be an
important indicator of corporate performance,  the stock prices of semiconductor
equipment  companies like Aehr Test Systems  are subject to  a number of market-
related   factors  other  than   company   performance,  such   as   competitive
announcements,  mergers and acquisitions in the industry,  the general  state of
the economy,  and  the  performance of  other  semiconductor  equipment  company
stocks.

                      COMPLIANCE WITH SECTION 16(A) OF THE
                         SECURITIES EXCHANGE ACT OF 1934

      Section  16(a)  of the  Exchange  Act  requires  that  directors,  certain
officers of the Company and ten percent  Shareholders  file reports of ownership
and  changes  in  ownership  with  the  SEC  as  to  the  Company's   securities
beneficially  owned by them.  Such  persons  are also  required  by SEC rules to
furnish the Company with copies of all Section 16(a) forms they file.

      Based  solely  on its  review  of  copies  of such forms  received by  the
Company,  or on  written  representations  from certain  reporting persons,  the
Company  believes that  all Section 16(a)  filing requirements applicable to its
officers, directors and greater than ten percent beneficial owners were complied
with during the fiscal year ended May 31, 2004.


                              FINANCIAL STATEMENTS

any other matters  properly come before the meeting,  it is the intention of the

                                      APPENDIX A

                                  AEHR TEST SYSTEMS
                               AUDIT COMMITTEE CHARTER

PURPOSE

The primary  purpose of the  Audit Committee (the "Committee") is to  assist the
Board  of  Directors (the "Board") in fulfilling  its responsibility  to oversee
management's conduct of the Company's financial reporting  process, including by
overviewing  the financial reports  and other financial information  provided by
the Company  to any governmental or  regulatory body,  the public or other users
thereof,  the Company's systems of  internal accounting  and financial controls,
and the annual independent audit of the Company's financial statements.

In discharging its oversight role, the Committee is empowered to investigate any
matter  brought  to  its  attention  with  full  access  to all books,  records,
facilities and personnel of the Company and the power to retain outside counsel,
auditors or other experts for this purpose.   The Board and the Committee are in
place to represent the Company's shareholders;  accordingly, the outside auditor
is ultimately accountable to the Board and the Committee.

The Committee shall review the adequacy of this Charter on an annual basis.

MEMBERSHIP

The Committee  shall be comprised of  members of the Board,  and the Committee's
composition  will meet  the  requirements of the  Audit Committee Policy  of the
NASD.

Accordingly, all of the members will be directors:

1.  Who have no relationship to the Company that may interfere with the exercise
    of their independence from management and the Company; and

2.  Who are  financially  literate or  who become financially  literate within a
    reasonable period of time after appointment to the Committee.   In addition,
    at  least  one member of the  Committee  will  have  accounting  or  related
    financial management expertise.

KEY RESPONSIBILITIES

The Committee's job is  one of  oversight and  it recognizes that  the Company's
management is  responsible for preparing the  Company's financial statements and
that  the  outside  auditors   are  responsible  for  auditing  those  financial
statements.

Additionally, the Committee recognizes that financial management, as well as the
outside auditors, have more time, knowledge and more detailed information on the
Company than do Committee members;  consequently,  in carrying out its oversight
responsibilities, the Committee is not providing any expert or special assurance
as to the Company's financial statements or any professional certification as to
the outside auditor's work.

The  following  functions  shall  be  the  common  recurring  activities  of the
Committee in carrying out its oversight function.  These functions are set forth
as a guide with the understanding that the Committee may diverge from this guide
as appropriate given the circumstances.

  o  The  Committee shall  review with management and  the outside  auditors the
     audited financial

                                       18


     statements    to   be   included   in    the   Company's   Annual    Report
     on Form 10-K  (or the Annual Report to Shareholders if distributed prior to
     the filing of Form 10-K) and  review and consider with the outside auditors
     the matters  required  to be  discussed by  Statement of Auditing Standards
     ("SAS") No. 61, as amended.

  o  As a whole, or through the Committee chair, the Committee shall review with
     the outside auditors the Company's interim financial results to be included
     in the Company's quarterly reports to be filed with Securities and Exchange
     Commission and  the matters required to be  discussed by  SAS No. 61;  this
     review will occur prior to the Company's filing of the Form 10-Q.

  o  The Committee shall:

       o  request from the outside auditors annually, a formal written statement
          delineating  all  relationships between  the auditor  and  the Company
          consistent with Independence Standards Board Standard Number 1;

       o  discuss with the outside auditors any such disclosed relationships and
          their impact on the outside auditor's independence; and

       o  recommend  that  the  Board  take  appropriate  action  to oversee the
          independence of the outside auditor.

  o  The Committee,  subject to any action that may be taken by  the full Board,
     shall have the ultimate authority and responsibility to select (or nominate
     for shareholder  approval),  evaluate and,  where appropriate,  replace the
     outside auditor.
