                                 PROXY STATEMENT

                       FOR ANNUAL MEETING OF STOCKHOLDERS

                             TO BE HELD MAY 10, 2005




         The enclosed proxy is furnished to the holders of common stock,  no par
value  (the  "Common  Stock"),  of  Essex  Corporation  (the  "Company")  and is
solicited by the Board of Directors of the Company for use at the Annual Meeting
of Stockholders to be held on May 10, 2005 and at any adjournments  thereof (the
"Annual  Meeting").  The approximate date on which the Notice of Annual Meeting,
Proxy  Statement and proxy card are first sent or given to stockholders is April
12, 2005.

         The shares  represented by all properly  executed proxies will be voted
at  the  Annual  Meeting  in  accordance  with  instructions   thereon.   If  no
instructions  are  indicated,  the  proxy  will be voted  FOR the  nominees  for
director  listed on the proxy and also  listed  under the caption  "Proposal  1"
herein;  FOR  ratification  of restatement of the Company's 2004 Stock Incentive
Plan to increase the number of shares reserved for the issuance  thereunder from
1,000,000 shares to 1,300,000, "Proposal 2"; and FOR ratification of appointment
of independent  registered public  accounting firm,  "Proposal 3". The Company's
Board of Directors recommends that the stockholders vote in favor of each of the
proposals.  All valid proxies  obtained  will be voted at the  discretion of the
Board of Directors  with respect to any other  business that may come before the
Annual Meeting.

         The Board of  Directors  has fixed the close of  business  on March 22,
2005  as  the  record  date  (the  "Record  Date")  for  the   determination  of
stockholders  entitled to notice of, and to vote at, the Annual  Meeting and any
adjournment thereof.

         As of the Record Date, there were outstanding  21,056,649 shares of the
Common  Stock.  Holders  of shares of Common  Stock of record as of the close of
business  on the Record  Date will be  entitled  to vote at the Annual  Meeting.
Holders of Common Stock are entitled to one vote on all matters presented at the
meeting  for each share held of record.  The  presence  in person or by proxy of
holders  of record of at least  one-third  of the shares  outstanding  as of the
Record  Date shall be required  for a quorum to transact  business at the Annual
Meeting. If a quorum should not be

                                       1




present, the Annual Meeting may be adjourned from time to time until a quorum is
obtained.  The  nominees to be selected  as  directors  named in Proposal 1 must
receive a  plurality  of the votes cast at the Annual  Meeting  with  respect to
Proposal 1. Proposals 2 and 3 must receive a greater number of affirmative votes
than negative votes cast at the Annual Meeting. Abstentions and broker non-votes
will  have no effect  on the  proposals  because  broker  non-votes  will not be
considered  as  present  or voting  and  abstentions  will be  counted  only for
purposes of determining whether there is a quorum.

         Proxies may be revoked  before they are voted at the Annual  Meeting by
giving written  notice of revocation to the Secretary,  by submission of a proxy
bearing a later date, or by attending the Annual Meeting in person and voting by
ballot.

         The  cost  of  preparing  and  mailing  this  Proxy  Statement  and the
accompanying  proxy card will be borne by the Company  and the Company  will pay
the cost of soliciting  proxies.  In addition to solicitation  by mail,  certain
officers  and regular  employees of the Company and  employees of the  Company's
Transfer  Agent may solicit the return of proxies by  telephone,  telegram or in
person. The Company will also reimburse brokers,  nominees and other fiduciaries
for their expenses in forwarding solicitation materials to the beneficial owners
of Common Stock and soliciting them to execute proxies.

         Any document  referenced in this Proxy  Statement is available  without
charge to any  stockholder  of record upon request.  All requests  shall be made
either in writing, and directed to the Company at its main office address,  9150
Guilford Road,  Columbia,  MD 21046,  or orally and directed to the Secretary at
301-939-7000.

                      THE BOARD OF DIRECTORS AND COMMITTEES

         The  Company's   Board  of  Directors  (the  "Board")   generally  meet
quarterly.  At such meetings,  the Company's independent  directors,  within the
meaning of Rule 10A-3(b) under the Exchange Act of 1934, as amended,  and Nasdaq
National  Market Rule  4200(a)(15),  who are  Messrs.  Hannon,  Hicks,  Johnson,

generally  meet in  executive  session.  Additionally,  the By-Laws  provide for
special  meetings and, as also  permitted by Virginia  law,  Board action may be
taken without a meeting upon unanimous written consent of all Directors. In 2004
the Board held four meetings;  the entire membership of the Board was present at
one of the  meetings,  two  directors  were  absent  from two  meetings  and one
director was absent from one meeting.

         The Board has two standing Committees:  the  audit  committee  and  the
ethics committee.

         AUDIT COMMITTEE. Our audit committee is established in accordance  with
Section 3(a)(58)(A) of the Exchange Act of 1934 as amended,  and composed of the
following  three  directors:  Messrs.  Hicks and Keeler and Ms. Minton.  Messrs.
Hicks and Keeler and Ms. Minton are independent  directors within the meaning of
the independence standards of audit committee members of SEC Rule 10A-3(b) under
the Securities  Exchange Act of 1934 in addition to the current  requirements of
the Nasdaq  National  Market  under  Rule  4200(a)(15).  Ms.  Minton is an audit
committee  financial  expert as defined by Item 401(h) of Regulation  S-K of the
Securities Act of 1933, as amended.

         The primary responsibilities of the audit committee are to:

       o Oversee  management's  conduct of our financial  reporting  process and
         systems of internal accounting and financial control;

       o Monitor the independence and  performance of our independent registered
         public accounting firm;

       o Provide an avenue of  communication  among the  independent  registered
         public accounting firm, management and our board of directors;

       o Make reports and  recommendations  to our board and our shareholders as
         necessary under the rules of the Securities and Exchange  Commission or
         as otherwise within the scope of its functions; and

       o Oversee and,  where  appropriate,  report to our board on our review of
         and response to any government audit, inquiry or investigation, as they
         determine to be appropriate.

         The  Board  has  implemented   all  necessary   changes  to  the  audit
committee's  charter to comply with Nasdaq's  revised listing  standards and may
consider  further changes to its charter and designated  responsibilities  as it
deems necessary and appropriate.  The Audit Committee's  responsibilities are as
described in the written  Charter  (Appendix A) adopted by the Board.  The Audit
Committee  held six meetings in 2004.  One member was absent from one of the six
meetings.

AUDIT COMMITTEE REPORT

         The Audit Committee consists of Messrs.  Hicks, Keeler and Ms.  Minton.
Messrs.  Hicks and Keeler and Ms. Minton are "independent  directors" within the
meaning of the  independence  standards of audit  committee  members of SEC Rule
10A-3(b)  under the  Securities  Exchange Act of 1934 in addition to the current
requirements of the Nasdaq National Market under Rule 4100(a)(15). Ms. Minton is
an audit committee  financial expert as defined by Item 401(h) of Regulation S-K
of  the   Securities   Act  of  1933,   as   amended.   The  Audit   Committee's
responsibilities  are as described in a written  Charter adopted by the Board of
Directors.

         In performing its oversight  responsibilities,  the Audit Committee has
reviewed  and  discussed  the  Company's  2004  consolidated  audited  financial
statements with the Company's management. The Audit Committee also has discussed
with the independent  registered public accounting firm, Stegman & Company,  the
matters  required to be discussed by  Statement  on Auditing  Standards  No. 61,
COMMUNICATIONS WITH AUDIT COMMITTEES,  which include, among other items, matters
related to the  conduct  of the audit of the  Company's  consolidated  financial
statements.

         The Audit  Committee has received  written  disclosures  and the letter
from  the  independent   registered   pubic  accounting  firm  required  by  the
Independence Standards Board Standard No. 1, INDEPENDENCE DISCUSSIONS WITH AUDIT
COMMITTEES  (which relates to the firm's  independence  from the corporation and
its related  entities) and has discussed with the firm their  independence  from
the Company.


         Based on these reviews and discussions, the Audit Committee recommended
to the Board of Directors that the Company's 2004 audited consolidated financial
statements be included in the Company's Annual Report on Form 10-K.

         The members of the Audit  Committee are not  professionally  engaged in
the  practice of  accounting  or  auditing  and are not experts in the fields of
accounting  or  auditing,  including  in respect of  accountant's  independence.
Members of the Audit  Committee  rely without  independent  verification  on the
information  provided to them and on the representations  made by management and
the  independent  registered  public  accounting  firm.  Accordingly,  the Audit
Committee's  oversight does not provide an  independent  basis to determine that
management  has  maintained   appropriate  accounting  and  financial  reporting
principles or appropriate  internal  controls and procedures  designed to assure
compliance  with  accounting  standards  and  applicable  laws and  regulations.
Furthermore,  the Audit Committee's considerations and discussions do not assure
that the  audit of the  Company's  consolidated  financial  statements  has been
carried out in accordance  with  auditing  standards  generally  accepted in the
United  States  of  America,  that the  consolidated  financial  statements  are
presented in accordance with  accounting  principles  generally  accepted in the
United States of America or that the  Company's  independent  registered  public
accounting firm are in fact "independent."

                                  Audit Committee

                                  Robert W. Hicks, Chairman
                                  Ray M. Keeler
                                  Marie S. Minton

         COMPENSATION.  The  requirements  of the Nasdaq  National  Market allow
companies  to  have  a  separate  Compensation  Committee  or  have  independent
directors of the Board vote on compensation related items. The Board agreed as a
whole to have independent directors act as the Compensation  Committee beginning
March 16, 2004.  The  Independent  Directors of the Board will  recommend to the
full Board the levels of compensation  paid to the Chief  Executive  Officer and
other  executive  officers.  In  particular,  the Board  based its review of the
compensation  for the CEO on such subjective  criteria as satisfaction of Essex'
financial goals (revenue and EPS) and completion of appropriate acquisitions. In
addition,  criteria included such subjective factors as investor  relations,  to
include  raising  funds,  and  creation of a strong  management  team to support
future growth.

         The Company's executive compensation program is designed to attract and
retain executives  responsible for the Company's  long-term  success,  to reward
executives for achieving both  financial and strategic  company goals,  to align
executive and stockholder  interests through long-term,  equity-based plans, and
to provide a compensation  package that recognizes  individual  contributions as
well as overall business  results.  As a result,  a substantial  portion of each
executive's total compensation is intended to be variable and to be tied closely
to the  achievement  of specific  business  objectives  and corporate  financial
goals,  as well as the  attainment  of the  executive's  individual  performance
objectives. The Company's executive compensation program also takes into account
the  compensation  practices of companies with whom Essex competes for executive
talent.  These companies (the "peer companies")  include the principal companies
included in the peer group  indices in the Stock  Performance  Graph  section of
this proxy statement and additional companies in various industries.

         The  three  key  components  of the  Company's  executive  compensation
program  are  base  salary,  variable  incentive  compensation,   and  long-term
incentive awards in the form of stock options.  Overall compensation is intended
to be competitive for comparable positions at the peer companies.

         ETHICS COMMITTEE.  Mr. Leonard  E. Moodispaw  and Mr. Frank E.  Manning
composed our ethics committee until April 2004.  Current members are Mr. Leonard
Moodispaw  and Mr. John G. Hannon.  The primary  responsibilities  of the ethics
committee are to:

              o   Advise our  management  and the entire  board of  directors of
                  means  of  ensuring  that we  adhere  to the  highest  ethical
                  standards in our day to day operations;

              o   Ensure  that a positive  working  environment  is created  and
                  maintained for all our employees and that those  employees are
                  challenged to meet such a standard;

              o   Provide  a forum  for  advice to the  corporate  counsel,  our
                  management  and  any  of our  employees  to  consider  ethical
                  issues; and

              o   Recommend to our  management and the entire board of directors
                  means of training managers and employees.

         The  Company  has  adopted a written  code of ethics  that is  publicly
available on the Company's website (WWW.ESSEXCORP.COM).

                                       7



DIRECTOR COMPENSATION

         Non-employee  members  of the board of  directors  receive a maximum of
$1,500 for each board  meeting and $750 for each board  committee  meeting  they
attend.  Such  members  are also  reimbursed  for travel  expenses  incurred  in
connection with their attendance at board and committee meetings. Two members of
the board of directors,  Arthur L. Money and Marie S. Minton, receive $1,500 per
month for serving on an informal committee of the board with Messrs.  Hannon and
Leonard.  The  members of our board of  directors  who are  affiliated  with our
significant  shareholders,  GEF and The Hannon Family LLC, have waived the right
to receive  any board fees.  Employee  directors  do not receive  fees for their
service on our board of directors.

         In  addition,  non-employee  members  of the  board  of  directors  are
eligible to participate in our Restricted Stock Bonus Plan. Shares of restricted
stock may be issued under this plan subject to  forfeiture  during a restriction
period, fixed in each instance by the board of directors,  whereby all rights of
the grantee to the stock terminate upon certain  conditions such as cessation of
continuous   membership  on  our  board  during  the  restriction  period.  Upon
expiration of the restriction  period,  or earlier upon the death or substantial
disability  of  the  grantee,  the  restrictions  applicable  to all  shares  of
restricted  stock of the grantee  expire.  While this plan also provides that we
may advance  loans to a grantee to pay income taxes due on the taxable  value of
shares granted under the plan, we have never issued any such loans. The Board of
Directors has prohibited these loans.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

         None of our  executive  officers  serves on the board of  directors  or
compensation  committee  of any entity that has one or more  executive  officers
serving as a member of our board of directors or compensation committee.

         DIRECTOR  NOMINATION  PROCESS.  The  Company's   Independent  Directors
perform the nominating  committee  functions in lieu of a formal committee.  The
Directors performing these functions are Messrs. Hannon, Hicks, Johnson, Keeler,
Money and Ms. Minton,  all independent  directors  within the meaning of current
Nasdaq  listing  rules.  The  Board  believes  it  is  more  effective  for  the
Independent  Directors  to  manage  the  process  of  structuring  the Board and
nominating candidates than to delegate to a committee. Because a majority of the
Board are independent, this decision saves time and cost for the entire Board.

         The Independent  Directors review potential candidates for the Board of
Directors  and  recommends  any  nominees  to the Board of  Directors  for their
consideration.  In reviewing potential candidates for the Board, the Independent
Directors considers among other things, the individual's  experience,  the needs
of the Company for an additional or replacement  director,  and the  candidate's
interest in the business of the Company.

         The Company  welcomes  nominations  from  shareholders  and  encourages
interested  shareholders  to  submit  candidates  to the  Independent  Directors
through the Secretary. The Company did not receive any recommended nominees from
any   shareholder  in  connection  with  the  previous  year's  annual  meeting.
Stockholders  can send nominations by e-mail to  kim.dechello@essexcorp.com,  by
fax to (301)  953-7880 or by mail to Kim DeChello,  Corporate

Secretary,  Essex  Corporation,  9150  Guilford  Road,  Columbia  MD 21046.  All
nominations   are  reviewed   based  on  their   qualifications   and  potential
contributions to Essex.

COMMUNICATION BETWEEN SHAREHOLDERS AND DIRECTORS

         The Board recommends that stockholders initiate any communications with
the  Board  in  writing  and  send  them  in care  of the  Corporate  Secretary.
Stockholders can send communications by e-mail to kim.dechello@essexcorp.com, by
fax to (301)  953-7880 or by mail to Kim DeChello,  Corporate  Secretary,  Essex
Corporation,  9150 Guilford Road,  Columbia MD 21046.  This centralized  process
will assist the Board in reviewing and responding to stockholder  communications
in an appropriate  manner.  The name of any specific  intended  Board  recipient
should be noted in the  communication.  The Board has  instructed  the Corporate
Secretary  to  forward  such  correspondence  only to the  intended  recipients;
however,  the  Board  has also  instructed  the  Corporate  Secretary,  prior to
forwarding  any  correspondence,  to  review  such  correspondence  and,  in her
discretion,  not to forward  certain items if they are deemed of a commercial or
frivolous nature or otherwise  inappropriate for the Board's  consideration.  In
such  cases,  some of that  correspondence  may be  forwarded  elsewhere  in the
company for review and possible response.

DIRECTOR ATTENDANCE AT ANNUAL MEETING
         It is the  policy  of the  Company  and  Board  of  Directors  that all
directors  attend  the Annual  Meeting  of  Shareholders  and be  available  for
questions from the shareholders.  All sitting  directors  nominated for election
were in  attendance  at the 2004  Annual  Meeting  of  Shareholders  except  for
Director Minton. It is anticipated that most directors nominated for election at
the 2005  Annual  Meeting of  Shareholders  also will be in  attendance  at that
meeting.

DEFINED CONTRIBUTION RETIREMENT PLAN

         The Essex Corporation  Retirement Plan and Trust is a qualified defined
contribution  retirement plan which includes a 401(k) salary  reduction  feature
for its employees.  This plan calls for an employer matching  contribution of up
to 4.5% of eligible employee compensation under the salary reduction feature and
a discretionary contribution as determined by the board of directors. We did not
make any discretionary  contribution between 2002 and 2004. The total authorized
contribution  under  the  matching   contribution   feature  of  this  plan  was
approximately  $458,000  in 2004,  $130,000  in 2003 and  $75,000  in 2002.  All
employee contributions are 100% vested at all times and our contributions, prior
to 2004,  vested based on length of service.  In accordance  with the retirement
plan and trust, as amended in 2004,  employees vested 100% in our contributions.
Vested contributions are distributable and benefits are payable only upon death,
disability,  retirement or break in service. Participants may request that their
accrued benefits under the Section 401(k) portion of the plan be allocated among
various investment options established by the plan administrator.

         The Company  terminated the qualified  defined  contribution and profit
sharing   retirement   plan  of  the  acquired   company,   Sensys   Development
Laboratories,  Inc., in December 2004.  Under this plan, the Company  recognized
the  required  contributions  of 8% or  approximately  $216,000 and $154,000 and
additional  contributions of 5% or approximately  $135,000 and $96,000, for 2004
and for the  period  since  acquisition,  March 1, 2003 to  December  28,  2003,
respectively.

         The Company  contributions  under the  Retirement  Plan for the persons
referred to in the Summary Compensation Table are included in that Table.

EMPLOYEE INCENTIVE PERFORMANCE AWARD PLAN

         The  Company  has an Employee  Incentive  Performance  Award Plan under
which  bonuses are  distributed  to  employees.  All  employees  are eligible to
receive such awards under flexible  criteria designed to compensate for superior
division  and  individual  performance  during  each  fiscal  year.  Awards  are
generally  recommended  annually  by  management  and  approved  by the board of
directors. These awards may be constrained by our overall financial performance.
In 2004, we paid approximately  $1.3 million,  including the $337,000 awarded to
the persons named in the Summary  Compensation  Table, under this plan. In 2003,
we paid approximately  $269,000,  including the $197,000 awarded to three of the
persons  named in the Summary  Compensation  Table,  under this plan. We did not
make any awards under this plan in 2002.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

         Section 16(a) of the  Securities  Exchange Act of 1934, as amended (the
"Exchange Act") requires the Company's  officers and directors,  and persons who
own  more  than ten  percent  of a  registered  class  of the  Company's  equity
securities (the "Reporting  Persons"),  to file reports of ownership and changes
in  ownership  of equity  securities  of the  Company  with the  Securities  and
Exchange Commission ("SEC").  Officers,  directors, and greater than ten percent
shareholders  are required by SEC regulations to furnish the Company with copies
of all Section 16(a) forms that they file.

                                       11


         Based  solely  upon a review  of Forms 3 and Forms 4  furnished  to the
Company  pursuant to Rule 16(a)-3  under the Exchange Act during its most recent
fiscal year and Forms 5 with respect to its most recent fiscal year, the Company
believes that all such forms  required to be filed  pursuant to Section 16(a) of
the Exchange Act were timely filed by the  Reporting  Persons  during the fiscal
year ended December 31, 2004.

OPTIONS TO PURCHASE SECURITIES

         The Company has established several stock option and stock appreciation
rights plans. These Plans provide for the grant of options to purchase shares of
common stock of the Company, no par value per share (the "Common Stock"),  which
qualify as incentive  stock options  ("Incentive  Options") under Section 422 of
the Internal  Revenue Code of 1986, as amended (the "Code"),  to persons who are
our employees,  as well as  non-qualified  options which do not so qualify to be
issued to persons or consultants,  including those who are not employees.  These
Plans  also  provide  for  grants  of stock  appreciation  rights,  or SARS,  in
connection with the grant of options under these Plans. The exercise price of an
Incentive  Option under these Plans may not be less than the "fair market value"
of the  shares  of  common  stock at the time of grant;  the  exercise  price of
Non-Qualified  Options and the appreciation base price of SARs are determined at
the discretion of the Board of Directors except that the SAR  appreciation  base
price may not be less than  100% of the fair  market  value of a share of common
stock on the grant date with  respect to awards to persons  who are  officers or
directors of the Company.  These Plans reserve  2,472,316 shares of Common Stock
for  issuance.  As of March 22, 2005,  there were 603,127  shares  available for
future grants of options or SARs under the Plans.

         The Company grants  non-plan,  non-qualified  options from time to time
directly to certain parties. In 2003, the Company issued such options for 30,000
shares to our Chief  Scientist  and 10,000 shares to our  Treasurer.  We did not
grant any non-plan, non-qualified options in 2004 or 2002.

               PROPOSAL 2 - AMENDMENT AND RESTATEMENT OF THE ESSEX
                      CORPORATION 2004 STOCK INCENTIVE PLAN

GENERAL

         The Company's  stockholders are being asked to approve an amendment and
restatement  of the  Company's  2004 Stock  Incentive  Plan (the  "2004  Plan").
Approval  of the  proposal  requires  the  affirmative  vote of the holders of a
majority of the shares of Common Stock  present or  represented  and entitled to
vote at the Annual Meeting.  Stockholders abstaining from voting on Proposal No.
2 will be counted for purposes of determining a quorum,  but will not be counted
for any other  purpose.  Broker  non-votes  will not be considered as present or
voting, and as such each will have no effect on the vote for this proposal.

         Subject to stockholder approval,  the Board of Directors of the Company
amended and restated the 2004 Plan in February  2005,  to increase the number of
shares  reserved  for  issuance  under  the 2004  Plan by  300,000  shares  from
1,000,000  shares to 1,300,000  shares,  subject to adjustment in the event of a
stock split,  stock  dividend,  or other  similar  change in the Common Stock or
capital  structure  of the  Company.  The 2004 Plan is  intended  to enable  the
Company to attract and retain the best  available  personnel for  positions,  to
provide  additional  incentive to employees,  directors and  consultants  and to
promote the  success of the  Company's  business.  The Board  believes  that the
Company's  long term  success is  dependent  upon the  ability of the Company to
attract and retain  superior  individuals  who,  by virtue of their  ability and
qualifications,  make important contributions to the Company.  Capitalized terms
used in this  Proposal  No. 2 shall  have the same  meaning  as in the 2004 Plan
unless otherwise indicated.

            THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR APPROVAL OF
                 THE AMENDMENT AND RESTATEMENT OF THE 2004 PLAN

         A  general  description  of the  principal  terms of the  2004  Plan as
amended and restated is set forth below.  This  description  is qualified in its
entirety by the terms of the amended and restated  2004 Plan, a copy of which is
attached to this Proxy  Statement  as Appendix A and is  incorporated  herein by
reference.

GENERAL DESCRIPTION
         PURPOSE.  The  purpose  of the 2004 Plan is to  provide  the  Company's
employees,  directors and consultants, whose present and potential contributions
are important to the success of the Company, an incentive,  through ownership of
the Company's  Common Stock, to continue in service to the Company,  and to help
the Company  compete  effectively  with other  enterprises  for the  services of
qualified individuals.

         As of March 22,  2005,  options  to  purchase  402,045  shares had been
granted  under the 2004 Plan of which  options to purchase  377,300  shares were
outstanding.  As of March  22,  2005,  no shares  of  restricted  stock had been
granted  under the 2004 Plan.  As of March 22,  2005,  the  number of  officers,
employees,  consultants  and  directors of the Company and its related  entities
that were eligible to receive grants under the 2004 Plan was  approximately  650
persons.
                                       22


         SHARES  RESERVED FOR ISSUANCE UNDER THE 2004 PLAN. If the amendment and
restatement  of the 2004 Plan is  approved  by the  stockholders,  the number of
shares  reserved for  issuance  under the 2004 Plan will be increased by 300,000
shares from 1,000,000 shares to 1,300,000 shares,  subject to adjustment only in
the event of a stock  split,  stock  dividend,  or other  similar  change in the
common stock or capital  structure of the Company.  The maximum number of shares
with respect to which options and stock appreciation  rights may be granted to a
participant  during a fiscal year of the Company is 500,000 shares. In addition,
in  connection  with a  participant's  commencement  of  continuous  service,  a
participant  may be granted options and stock  appreciation  rights for up to an
additional  500,000  shares which shall not count against the limit set forth in
the previous sentence. For awards of restricted stock and restricted stock units
that are intended to be  performance-based  compensation under Section 162(m) of
the Internal  Revenue  Code of 1986,  as amended,  the maximum  number of shares
subject to such awards that may be granted to a participant during a fiscal year
of the Company is 500,000 shares.

         ADMINISTRATION.  The 2004 Plan is administered,  with respect to grants
to employees,  directors,  officers, and consultants,  by the plan administrator
(the "Administrator"), defined as the Board or one or more committees designated
by the Board.  With respect to grants to officers and  directors,  the committee
shall be constituted in such a manner as to satisfy  applicable laws,  including
Rule 16b-3 promulgated under the Securities Exchange Act of 1934, as amended and
Section 162(m) of Code.

         TERMS AND CONDITIONS OF AWARDS. The 2004 Plan provides for the grant of
stock options,  restricted  stock,  restricted stock units,  stock  appreciation
rights and dividend  equivalent rights  (collectively  referred to as "awards").
Stock options granted under the 2004 Plan may be either  incentive stock options
under the provisions of Section 422 of the Code, or nonqualified  stock options.
Incentive  stock  options may be granted  only to  employees.  Awards other than
incentive stock options may be granted to employees,  directors and consultants.
Under the 2004  Plan,  awards may be granted  to such  employees,  directors  or
consultants who are residing in non-U.S.  jurisdictions as the Administrator may
determine from time to time.

         Subject to applicable laws, the Administrator has the authority, in its
discretion, to select employees, directors and consultants to whom awards may be
granted from time to time,  to determine  whether and to what extent  awards are
granted,  to determine the number of shares of the Company's Common Stock or the
amount of other  consideration  to be  covered  by each  award  (subject  to the
limitations  set forth  under  the  above  section  of this  Proposal  2 "SHARES
RESERVED FOR ISSUANCE UNDER THE 2004 PLAN"), to approve award agreements for use
under the 2004 Plan,  to determine  the terms and  conditions  of any award,  to
construe  and  interpret  the  terms of the 2004  Plan and  awards  granted,  to
establish additional terms,  conditions,  rules or procedures to accommodate the
rules or laws of applicable non-U.S. jurisdictions and to take such other action
not  inconsistent  with the  terms of the 2004 Plan as the  Administrator  deems
appropriate.

         Each award  granted under the 2004 Plan shall be designated in an award
agreement. In the case of an option, the option shall be designated as either an
incentive  stock option or a nonqualified  stock option.  To the extent that the
aggregate  fair market value of shares of the Company's  Common Stock subject to
options  designated as incentive stock options which become  exercisable for the
first time by a  participant  during any calendar  year exceeds  $100,000,  such
excess options shall be treated as nonqualified stock options.

                                       23


         The term of any award  granted  under the 2004 Plan may not be for more
than seven years (or five years in the case of incentive  stock options  granted
to any  participant  who owns stock  representing  more than 10% of the combined
voting  power of the  Company  or any  parent  or  subsidiary  of the  Company),
excluding any period for which the  participant has elected to defer the receipt
of the shares or cash issuable pursuant to the award.

         The 2004 Plan  authorizes  the  Administrator  to grant  options  at an
exercise  price not less than 100% of the fair market  value of the common stock
on the date the  option is  granted  (or 110%,  in the case of  incentive  stock
options granted to any employee who owns stock representing more than 10% of the
combined  voting  power  of the  Company  or any  parent  or  subsidiary  of the
Company).  In the case of a stock  appreciation  right, the base amount on which
the stock  appreciation  is  calculated  shall be not less than 100% of the fair
market  value of the common stock on the date of grant.  The  exercise  price is
generally  payable in cash,  check,  shares of common  stock or with  respect to
options, payment through a broker-dealer sale and remittance procedure.

         The 2004 Plan provides that (a) any reduction of the exercise  price of
any option awarded under the 2004 Plan shall be subject to stockholder  approval
and (b)  canceling  any  option  awarded  under the 2004 Plan at a time when its
exercise  price  exceeds  the fair  market  value of the  underlying  shares  in
exchange for another award shall be subject to stockholder approval.

         Under  the 2004  Plan,  the  Administrator  may  establish  one or more
programs  under the 2004 Plan to permit  selected  grantees the  opportunity  to
elect  to  defer  receipt  of   consideration   payable  under  an  award.   The
Administrator  also may establish under the 2004 Plan separate  programs for the
grant of  particular  forms of awards to one or more  classes of  grantees.  The
awards may be granted subject to vesting  schedules and restrictions on transfer
and repurchase or forfeiture  rights in favor of the Company as specified in the
award agreements to be issued under the 2004 Plan.

         TERMINATION  OF  SERVICE.  An  award  may not be  exercised  after  the
termination date of such award as set forth in the award agreement. In the event
a participant in the 2004 Plan terminates  continuous  service with the Company,
an award may be exercised  only to the extent  provided in the award  agreement.
Where an award  agreement  permits a participant to exercise an award  following
termination of service, the award shall terminate to the extent not exercised on
the last day of the specified period or the last day of the original term of the
award, whichever comes first. Any award designated as an incentive stock option,
to the extent not exercised within the time permitted by law for the exercise of
incentive stock options  following the termination of employment,  shall convert
automatically to a nonqualified stock option and thereafter shall be exercisable
as such to the extent  exercisable by its terms for the period  specified in the
award agreement.

         TRANSFERABILITY OF AWARDS. Under the 2004 Plan, incentive stock options
may not be sold, pledged, assigned, hypothecated,  transferred or disposed of in
any manner other than by will or by the laws of descent or distribution  and may
be exercised  during the lifetime of the  participant  only by the  participant.
Other  awards  shall be  transferable  only by will or by the laws of descent

                                       24


or distribution and to the extent provided in the award agreement. The 2004 Plan
permits  the  designation  of  beneficiaries  by holders  of  awards,  including
incentive stock options.

         SECTION  162(M) OF THE CODE.  The maximum number of shares with respect
to which options and stock  appreciation  rights may be granted to a participant
during  a  fiscal  year of the  Company  is  500,000  shares.  In  addition,  in
connection  with  a  participant's   commencement  of  continuous   service,   a
participant  may be granted options and stock  appreciation  rights for up to an
additional  500,000  shares which shall not count against the limit set forth in
the   previous   sentence.   The   foregoing   limitations   shall  be  adjusted
proportionately  by the  Administrator  in  connection  with any  change  in the
Company's  capitalization  due to a stock split, stock dividend or similar event
affecting the common stock of the Company and its determination  shall be final,
binding and conclusive. Under Code Section 162(m) no deduction is allowed in any
taxable year of the Company for  compensation  in excess of $1 million paid to a
Covered Employee. An exception to this rule applies to compensation that is paid
pursuant to a stock incentive plan approved by stockholders  and that specifies,
among other things,  the maximum  number of shares with respect to which options
and stock appreciation rights may be granted to eligible participants under such
plan during a specified  period.  Compensation paid pursuant to options or stock
appreciation  rights  granted under such a plan and with an exercise price equal
to the fair market value of the  Company's  Common Stock on the date of grant is
deemed to be inherently  performance-based,  since such awards  provide value to
participants  only if the stock  price  appreciates.  To the extent  required by
Section  162(m)  of the Code or the  regulations  thereunder,  in  applying  the
foregoing limitation, if any option or stock appreciation right is canceled, the
cancelled  award shall continue to count against the maximum number of shares of
Common Stock with respect to which an award may be granted to a participant.

         For awards of  restricted  stock and  restricted  stock  units that are
intended to be performance-based  compensation under Section 162(m) of the Code,
the  maximum  number of shares  subject to such  awards that may be granted to a
participant  during a fiscal year of the Company is 500,000 shares. In order for
restricted  stock and  restricted  stock  units to qualify as  performance-based
compensation,  the Administrator  must establish a performance goal with respect
to such award in writing  not later than 90 days after the  commencement  of the
services to which it relates and while the outcome is  substantially  uncertain.
In  addition,  the  performance  goal must be  stated  in terms of an  objective
formula or standard.  The 2004 Plan contains the following  list of  performance
criteria   that  may  be   considered   by  the   Administrator   when  granting
performance-based  awards: (i) increase in share price, (ii) earnings per share,
(iii) total stockholder  return,  (iv) operating margin, (v) gross margin,  (vi)
return on equity,  (vii) return on assets,  (viii)  return on  investment,  (ix)
operating  income,  (x) net operating  income,  (xi) pre-tax profit,  (xii) cash
flow, (xiii) revenue, (xiv) expenses,  (xv) earnings before interest,  taxes and
depreciation,  (xvi)  economic  value  added,  (xvii)  market  share and (xviii)
personal management objectives.

         CHANGE  IN  CAPITALIZATION.  Subject  to  any  required  action  by the
stockholders  of the Company,  the number of shares of common  stock  covered by
outstanding  awards,  the  number  of  shares  of  common  stock  that have been
authorized  for issuance  under the 2004 Plan, the exercise or purchase price of
each outstanding award, the maximum number of shares of common stock that may be
granted  subject to awards to any  participant  in a fiscal year,  and the like,
shall be  proportionally  adjusted by the  Administrator in the event of (i) any
increase or decrease in the

                                       25


number of issued  shares of common stock  resulting  from a stock  split,  stock
dividend,  combination or reclassification or similar event affecting the common
stock of the  Company,  (ii) any other  increase  or  decrease  in the number of
issued shares of common stock effected  without receipt of  consideration by the
Company or (iii) as the Administrator may determine in its discretion, any other
transaction  with  respect  to  common  stock  including  a  corporate   merger,
consolidation,  acquisition  of  property  or  stock,  separation  (including  a
spin-off  or  other   distribution   of  stock  or  property),   reorganization,
liquidation (whether partial or complete) or any similar transaction;  provided,
however, that conversion of any convertible  securities of the Company shall not
be  deemed  to have been  "effected  without  receipt  of  consideration."  Such
adjustment shall be made by the  Administrator  and its  determination  shall be
final, binding and conclusive.

         CORPORATE  TRANSACTION.  Effective upon the consummation of a corporate
transaction  (as  defined  in the  2004  Plan),  all  outstanding  awards  shall
terminate.  However,  all such  awards  shall not  terminate  to the  extent the
contractual  obligations  represented  by the award are assumed by the successor
entity.  In the event an  outstanding  award is not  assumed or  replaced by the
successor  entity in connection  with a corporate  transaction,  the award shall
automatically  become fully vested and  exercisable for all of the shares at the
time represented by the award, immediately prior to the specified effective date
of such corporate transaction.

         CHANGE IN  CONTROL.  In the event of a change in control (as defined in
the 2004 Plan), all outstanding awards shall  automatically  become fully vested
and  exercisable  for all of the  shares at the time  represented  by the award,
immediately prior to the specified effective date of such change in control.

         AMENDMENT, SUSPENSION OR TERMINATION OF THE 2004 PLAN. The Board may at
any time amend, suspend or terminate the 2004 Plan. The 2004 Plan will terminate
ten years from the date of its approval by the  Company's  stockholders,  unless
terminated  earlier  by the  Board.  To the  extent  necessary  to  comply  with
applicable provisions of federal securities laws, state corporate and securities
laws, the Code, the rules of any  applicable  stock exchange or national  market
system, and the rules of any non-U.S.  jurisdiction applicable to awards granted
to residents therein,  the Company shall obtain stockholder approval of any such
amendment to the 2004 Plan in such a manner and to such a degree as required.

CERTAIN FEDERAL TAX CONSEQUENCES

         The following  summary of the federal income tax  consequences  of 2004
Plan transactions is based upon federal income tax laws in effect on the date of
this proxy statement. This summary does not purport to be complete, and does not
discuss non-U.S., state or local tax consequences or guidance that may be issued
by the Treasury Department under Section 409A of the Internal Revenue Code.

         NONQUALIFIED  STOCK OPTIONS.  The grant of a nonqualified  stock option
under the 2004 Plan will not result in any federal  income tax  consequences  to
the participant or to the Company. Upon exercise of a nonqualified stock option,
the  participant  is subject to income taxes at the rate  applicable to ordinary
compensation  income on the difference between the option exercise price and the
fair market value of the shares on the date of exercise.  This income is subject
to
                                       26



withholding  for federal  income and  employment  tax  purposes.  The Company is
entitled to an income tax  deduction in the amount of the income  recognized  by
the participant,  subject to possible  limitations  imposed by Section 162(m) of
the Code and so long as the Company withholds the appropriate taxes with respect
to such income (if required) and the participant's  total compensation is deemed
reasonable  in  amount.  Any  gain  or  loss  on  the  participant's  subsequent
disposition  of the  shares of common  stock  will  receive  long or  short-term
capital  gain or loss  treatment,  depending  on whether the shares are held for
more  than one year  following  exercise.  The  Company  does not  receive a tax
deduction for any such gain.

         In the event a nonqualified stock option is amended, such option may be
considered deferred compensation and subject to the rules of new Section 409A of
the Code,  which  provide  rules  regarding  the timing of  payment of  deferred
compensation.  An option  subject  to Section  409A of the Code  which  fails to
comply  with the rules of  Section  409A,  can result in an  additional  20% tax
obligation,  plus  penalties and interest.  Currently how the additional tax and
penalties and interest will be applied is unclear.

         INCENTIVE  STOCK OPTIONS.  The grant of an incentive stock option under
the 2004 Plan will not  result in any  federal  income tax  consequences  to the
participant  or to the Company.  A  participant  recognizes  no federal  taxable
income upon  exercising an incentive  stock option  (subject to the  alternative
minimum tax rules discussed below), and the Company receives no deduction at the
time of exercise.  In the event of a disposition of stock acquired upon exercise
of an incentive  stock  option,  the tax  consequences  depend upon how long the
participant  has held the shares of common stock.  If the  participant  does not
dispose of the shares  within two years  after the  incentive  stock  option was
granted, nor within one year after the incentive stock option was exercised, the
participant  will  recognize  a  long-term  capital  gain (or loss) equal to the
difference  between  the sale price of the shares and the  exercise  price.  The
Company is not entitled to any deduction under these circumstances.

         If the  participant  fails to satisfy  either of the foregoing  holding
periods, he or she must recognize ordinary income in the year of the disposition
(referred  to as a  "disqualifying  disposition").  The amount of such  ordinary
income generally is the lesser of (i) the difference between the amount realized
on the  disposition  and the exercise price or (ii) the  difference  between the
fair market value of the stock on the exercise date and the exercise price.  Any
gain in excess of the amount taxed as ordinary  income will be treated as a long
or  short-term  capital  gain,  depending on whether the stock was held for more
than one year. The Company,  in the year of the  disqualifying  disposition,  is
entitled to a deduction equal to the amount of ordinary income recognized by the
participant,  subject to possible  limitations  imposed by Section 162(m) of the
Code and so long as the participant's total compensation is deemed reasonable in
amount.

         The "spread"  under an incentive  stock option -- i.e.,  the difference
between the fair market value of the shares at exercise  and the exercise  price
-- is  classified  as an item of adjustment in the year of exercise for purposes
of the  alternative  minimum  tax. If a  participant's  alternative  minimum tax
liability  exceeds  such  participant's   regular  income  tax  liability,   the
participant  will owe the  larger  amount  of  taxes.  In  order  to  avoid  the
application of alternative  minimum tax with respect to incentive stock options,
the participant  must sell the shares within the same calendar year in which the
incentive stock options are exercised. However, such a sale

                                       27


of shares  within the same year of  exercise  will  constitute  a  disqualifying
disposition, as described above.

         In the event an incentive  stock option is amended,  such option may be
considered deferred compensation and subject to the rules of new Section 409A of
the Code,  which  provide  rules  regarding  the timing of  payment of  deferred
compensation.  An option  subject  to Section  409A of the Code  which  fails to
comply  with the rules of  Section  409A,  can result in an  additional  20% tax
obligation,  plus  penalties and interest.  Currently how the additional tax and
penalties and interest will be applied is unclear. In addition, the amendment of
an incentive  stock option may convert the option from an incentive stock option
to a nonqualified stock option.

         RESTRICTED  STOCK.  The grant of  restricted  stock  will  subject  the
recipient to ordinary  compensation  income on the difference between the amount
paid for such stock and the fair market value of the shares on the date that the
restrictions lapse. This income is subject to withholding for federal income and
employment  tax purposes.  The Company is entitled to an income tax deduction in
the  amount of the  ordinary  income  recognized  by the  recipient,  subject to
possible  limitations  imposed by Section  162(m) of the Code and so long as the
Company  withholds  the  appropriate  taxes  with  respect  to such  income  (if
required)  and the  participant's  total  compensation  is deemed  reasonable in
amount. Any gain or loss on the recipient's subsequent disposition of the shares
will receive long or short-term capital gain or loss treatment  depending on how
long the stock has been held since the restrictions lapsed. The Company does not
receive a tax deduction for any such gain.

         Recipients of restricted stock may make an election under Section 83(b)
of the Code  ("Section  83(b)  Election") to recognize as ordinary  compensation
income in the year that such  restricted  stock is granted,  the amount equal to
the spread  between the amount paid for such stock and the fair market  value on
the  date of the  issuance  of the  stock.  If such an  election  is  made,  the
recipient recognizes no further amounts of compensation income upon the lapse of
any restrictions and any gain or loss on subsequent  disposition will be long or
short-term  capital gain to the  recipient.  The Section 83(b)  Election must be
made within thirty days from the time the restricted stock is issued.

         STOCK  APPRECIATION  RIGHTS.  Recipients of stock  appreciation  rights
("SARS")  generally  should  not  recognize  income  until the SAR is  exercised
(assuming  there is no ceiling on the value of the right).  Upon  exercise,  the
participant will normally  recognize  taxable ordinary income for federal income
tax purposes  equal to the amount of cash and fair market  value the shares,  if
any, received upon such exercise. Participants who are employees will be subject
to  withholding  for federal  income and employment tax purposes with respect to
income recognized upon exercise of an SAR. Participants will recognize gain upon
the disposition of any shares received on exercise of an SAR equal to the excess
of (i) the amount  realized on such  disposition  over (ii) the ordinary  income
recognized  with  respect to such shares under the  principles  set forth above.
That gain will be  taxable  as long or  short-term  capital  gain  depending  on
whether the shares were held for more than one year.

         The Company  will be entitled to a tax  deduction  to the extent and in
the year that  ordinary  income is  recognized  by the  participant,  subject to
possible  limitations  imposed by Section  162(m) of the Code and so long as the
Company  withholds  the  appropriate  taxes  with  respect  to

                                       28


such income (if required) and the  participant's  total  compensation  is deemed
reasonable in amount.

         To the  extent  that  an SAR is  settled  in  cash,  such  SAR  will be
considered deferred compensation and subject to the rules of new Section 409A of
the Code,  which  provide  rules  regarding  the timing of  payment of  deferred
compensation.  An SAR subject to Section  409A of the Code which fails to comply
with the rules of Section 409A, can result in an additional 20% tax  obligation,
plus penalties and interest.  Currently how the additional tax and penalties and
interest will be applied is unclear.

         RESTRICTED STOCK UNITS.  Recipients of restricted stock units generally
should not recognize  income until such units are converted  into cash or shares
of stock.  Upon  conversion,  the participant  will normally  recognize  taxable
ordinary  income for federal income tax purposes equal to the amount of cash and
fair  market  value  the  shares,   if  any,   received  upon  such  conversion.
Participants who are employees will be subject to withholding for federal income
and employment tax purposes with respect to income recognized upon conversion of
the  restricted  stock  units.   Participants   will  recognize  gain  upon  the
disposition of any shares received upon conversion of the restricted stock units
equal to the excess of (i) the amount realized on such disposition over (ii) the
ordinary income  recognized with respect to such shares under the principles set
forth  above.  That gain will be  taxable  as long or  short-term  capital  gain
depending on whether the shares were held for more than one year.

         The Company  will be entitled to a tax  deduction  to the extent and in
the year that  ordinary  income is  recognized  by the  participant,  subject to
possible  limitations  imposed by Section  162(m) of the Code and so long as the
Company  withholds  the  appropriate  taxes  with  respect  to such  income  (if
required)  and the  participant's  total  compensation  is deemed  reasonable in
amount.

         Restricted  stock units also can be considered  non-qualified  deferred
compensation  and  subject to the rules of new Section  409A of the Code,  which
provide rules regarding the timing of payment of deferred compensation.  A grant
of restricted  stock units that does not meet the  requirements  of Code Section
409A  will  result in an  additional  20% tax  obligation,  plus  penalties  and
interest to such participant.  Currently,  how the additional tax, penalties and
interest will be applied is unclear.

         DIVIDENDS AND DIVIDEND  EQUIVALENTS.  Recipients of stock-based  awards
that earn  dividends or dividend  equivalents  will recognize  taxable  ordinary
income on any  dividend  payments  received  with  respect  to  unvested  and/or
unexercised  shares  subject  to  such  awards,   which  income  is  subject  to
withholding  for federal  income and  employment  tax  purposes.  The Company is
entitled to an income tax deduction in the amount of the income  recognized by a
participant,  subject to possible  limitations  imposed by Section 162(m) of the
Code and so long as the Company  withholds the appropriate taxes with respect to
such income (if  required) and the  individual's  total  compensation  is deemed
reasonable in amount.

granted under the Plan,  provided that (A) any  amendment  that would  adversely
affect the Grantee's rights under an outstanding Award shall not be made without
the Grantee's  written  consent,  (B) the reduction of the exercise price of any
Option awarded under the Plan shall be subject to  stockholder  approval and (C)
canceling  an Option at a time when its exercise  price  exceeds the Fair Market
Value of the  underlying  Shares,  in exchange  for another  Option,  Restricted
Stock,  or other  Award  shall be subject to  stockholder  approval,  unless the
cancellation and exchange occurs in connection with a Corporate Transaction;

                           (vii) to construe and interpret the terms of the Plan
and  Awards,  including  without  limitation,  any  notice  of  award  or  Award

                           (ix) to take such other action, not inconsistent with
the terms of the Plan, as the Administrator deems appropriate.

                  (c)  INDEMNIFICATION.  In  addition  to such  other  rights of

Employees  of the  Company  or a Related  Entity,  members  of the Board and any
Officers or  Employees of the Company or a Related  Entity to whom  authority to
act for the  Board,  the  Administrator  or the  Company is  delegated  shall be
defended  and  indemnified  by the Company to the extent  permitted by law on an
after-tax  basis against all reasonable  expenses,  including  attorneys'  fees,
actually and  necessarily  incurred in connection with the defense of any claim,

therein,  to which  they or any of them may be a party by reason  of any  action
taken or  failure  to act under or in  connection  with the  Plan,  or any Award
granted  hereunder,  and against all amounts paid by them in settlement  thereof
(provided  such  settlement  is  approved  by the  Company)  or  paid by them in
satisfaction  of a judgment in any such claim,  investigation,  action,  suit or
proceeding,  except in  relation  to matters as to which it shall be adjudged in

designated as Incentive  Stock Options  which become  exercisable  for the first
time by a Grantee  during any  calendar  year (under all plans of the Company or
any Parent or Subsidiary of the Company) exceeds $100,000,  such excess Options,
to the  extent  of  the  Shares  covered  thereby  in  excess  of the  foregoing
limitation,  shall be treated as Non-Qualified Stock Options.  For this purpose,
Incentive  Stock  Options shall be taken into account in the order in which they
were granted,  and the Fair Market Value of the Shares shall be determined as of
the grant date of the relevant Option.

                  (c) CONDITIONS OF AWARD. Subject to the terms of the Plan, the
Administrator  shall  determine the  provisions,  terms,  and conditions of each
Award  including,  but not limited to, the Award  vesting  schedule,  repurchase
provisions,  rights of first  refusal,  forfeiture  provisions,  form of payment
(cash,  Shares, or other  consideration)  upon settlement of the Award,  payment
contingencies,  and  satisfaction of any performance  criteria.  The performance
criteria  established  by the  Administrator  may be  based  on any one  of,  or
combination  of, the following:  (i) increase in share price,  (ii) earnings per
share, (iii) total stockholder  return, (iv) operating margin, (v) gross margin,
(vi) return on equity, (vii) return on assets, (viii) return on investment, (ix)
operating  income,  (x) net operating  income,  (xi) pre-tax profit,  (xii) cash
flow, (xiii) revenue, (xiv) expenses,  (xv) earnings before interest,  taxes and
depreciation,  (xvi)  economic  value  added,  (xvii)  market  share and (xviii)
personal  management  objectives.  Partial achievement of the specified criteria
may result in a payment or vesting corresponding to the degree of achievement as
specified in the Award Agreement.

                  (d) ACQUISITIONS AND OTHER TRANSACTIONS. The Administrator may
issue Awards  under the Plan in  settlement,  assumption  or  substitution  for,
outstanding  awards or obligations to grant future awards in connection with the
Company or a Related Entity  acquiring  another  entity,  an interest in another
entity or an additional  interest in a Related Entity  whether by merger,  stock
purchase, asset purchase or other form of transaction.

                  (e) DEFERRAL OF AWARD PAYMENT. The Administrator may establish
one or more programs under the Plan to permit selected  Grantees the opportunity
to  elect  to  defer  receipt  of  consideration  upon  exercise  of  an  Award,
satisfaction  of performance  criteria,  or other event that absent the election
would entitle the Grantee to payment or receipt of Shares or other consideration
under an Award. The  Administrator  may establish the election  procedures,  the
timing of such  elections,  the  mechanisms  for  payments  of,  and  accrual of
interest or other earnings, if any, on amounts, Shares or other consideration so
deferred,  and such  other  terms,  conditions,  rules and  procedures  that the
Administrator  deems  advisable  for the  administration  of any  such  deferral
program.

                  (f) SEPARATE PROGRAMS.  The Administrator may establish one or
more  separate  programs  under the Plan for the  purpose of issuing  particular
forms of Awards to one or more classes of Grantees on such terms and  conditions
as determined by the Administrator from time to time.

                  (g) INDIVIDUAL LIMITATIONS ON AWARDS.

(i)  INDIVIDUAL  LIMIT FOR OPTIONS AND SARS.  The maximum  number of Shares with
respect to which  Options  and SARs may be granted to any  Grantee in any fiscal
year of the Company  shall be 500,000  Shares.  In  connection  with a Grantee's
commencement of 

                                      A-9


Continuous  Service,  a  Grantee  may be  granted  Options  or SARs for up to an
additional  500,000  Shares which shall not count against the limit set forth in
the   previous   sentence.   The   foregoing   limitations   shall  be  adjusted
proportionately  in connection  with any change in the Company's  capitalization
pursuant to Section 10, below.  To the extent  required by Section 162(m) of the
Code or the regulations  thereunder,  in applying the foregoing limitations with
respect to a Grantee,  if any Option or SAR is canceled,  the canceled Option or
SAR shall continue to count against the maximum number of Shares with respect to
which  Options and SARs may be granted to the  Grantee.  For this  purpose,  the
repricing  of an Option (or in the case of a SAR,  the base  amount on which the
stock  appreciation  is calculated is reduced to reflect a reduction in the Fair
Market Value of the Common  Stock) shall be treated as the  cancellation  of the
existing Option or SAR and the grant of a new Option or SAR.

(ii)  INDIVIDUAL  LIMIT FOR  RESTRICTED  STOCK AND RESTRICTED  STOCK UNITS.  For
awards of Restricted  Stock and  Restricted  Stock Units that are intended to be
Performance-Based  Compensation,  the maximum  number of Shares with  respect to
which  such  Awards may be  granted  to any  Grantee  in any fiscal  year of the
Company  shall be 500,000  Shares.  The foregoing  limitation  shall be adjusted
proportionately  in connection  with any change in the Company's  capitalization
pursuant to Section 10, below.

(iii)  DEFERRAL.  If the vesting or receipt of Shares under an Award is deferred
to a later  date,  any amount  (whether  denominated  in Shares or cash) paid in
addition  to the  original  number of Shares  subject  to such Award will not be
treated  as an  increase  in the  number of Shares  subject  to the Award if the
additional  amount is based either on a reasonable rate of interest or on one or
more  predetermined  actual  investments  such that the  amount  payable  by the
Company  at the  later  date  will be based on the  actual  rate of  return of a
specific investment (including any decrease as well as any increase in the value
of an investment).

                  (h) EARLY  EXERCISE.  The Award  Agreement  may, but need not,
include a provision whereby the Grantee may elect at any time while an Employee,
Director or  Consultant  to exercise  any part or all of the Award prior to full
vesting of the Award. Any unvested Shares received pursuant to such exercise may
be subject to a repurchase  right in favor of the Company or a Related Entity or
to any other restriction the Administrator determines to be appropriate.

                  (i) TERM OF  AWARD.  The term of each  Award  shall be no more
than seven (7) years from the date of grant  thereof  (excluding  any period for
which the  Grantee  has  elected  to defer  the  receipt  of the  Shares or cash
issuable  pursuant to the Award).  However,  in the case of an  Incentive  Stock
Option  granted to a Grantee who, at the time the Option is granted,  owns stock
representing  more than ten percent  (10%) of the voting power of all classes of
stock of the Company or any Parent or Subsidiary of the Company, the term of the
Incentive Stock Option shall be five (5) years from the date of grant thereof or
such  shorter  term as may be provided  in the Award  Agreement  (excluding  any
period for which the  Grantee  has  elected  to defer the  receipt of the Shares
issuable pursuant to the Incentive Stock Option).

                  (j) TRANSFERABILITY OF AWARDS. Incentive Stock Options may not
be sold, pledged,  assigned,  hypothecated,  transferred,  or disposed of in any
manner other than by will or by the laws of descent or  distribution  and may be
exercised,   during  the  lifetime  of  the   Grantee,   only  by  the  Grantee.
Non-Qualified  Stock Options and other Awards shall be transferable  (i) by will
or by the laws of descent and  distribution  and (ii) during the lifetime of the
Grantee,  to the  extent

                                      A-10


and  in  the  manner  authorized  by  the  Administrator.   Notwithstanding  the
foregoing,  the Grantee may designate one or more beneficiaries of the Grantee's
Incentive  Stock  Option  or  Non-Qualified  Stock  Option  in the  event of the
Grantee's death on a beneficiary designation form provided by the Administrator.

                  (k)  TIME OF  GRANTING  AWARDS.  The date of grant of an Award
shall  for all  purposes  be the  date on  which  the  Administrator  makes  the
determination  to grant such Award,  or such other date as is  determined by the
Administrator.

         7. AWARD EXERCISE OR PURCHASE PRICE, CONSIDERATION AND TAXES.

                  (a)  EXERCISE  OR  PURCHASE  PRICE.  The  exercise or purchase
price, if any, for an Award shall be as follows:

                           (i) In the case of an Incentive Stock Option:

                                    (A) granted to an Employee  who, at the time
of the grant of such Incentive  Stock Option owns stock  representing  more than
ten percent  (10%) of the voting power of all classes of stock of the Company or
any Parent or Subsidiary of the Company,  the per Share  exercise price shall be
not less than one hundred ten percent  (110%) of the Fair Market Value per Share
on the date of grant; or

                                    (B)  granted to any  Employee  other than an
Employee  described in the preceding  paragraph,  the per Share  exercise  price
shall be not less than one hundred  percent  (100%) of the Fair Market Value per
Share on the date of grant.

                           (ii) In the case of Non-Qualified Stock Options,  the
exercise  price  shall be not less than one hundred  percent  (100%) of the Fair
Market Value per Share on the date of grant.

                           (iii)  In the case of  SARs,  the  base  appreciation
amount  shall be not less than one  hundred  percent  (100%) of the Fair  Market
Value per Share on the date of grant.

                           (iv) In the case of other  Awards,  such  price as is
determined by the Administrator.

                           (v) Notwithstanding the foregoing  provisions of this
Section 7(a), in the case of an Award issued pursuant to Section 6(d) above, the
exercise or purchase price for the Award shall be determined in accordance  with
the provisions of the relevant instrument evidencing the agreement to issue such
Award.

                  (b)   CONSIDERATION.   Subject   to   Applicable   Laws,   the
consideration  to be paid for the Shares to be issued upon  exercise or purchase
of an  Award  including  the  method  of  payment,  shall be  determined  by the
Administrator  (and,  in  the  case  of an  Incentive  Stock  Option,  shall  be
determined  at  the  time  of  grant).   In  addition  to  any  other  types  of
consideration the  Administrator may determine,  the Administrator is authorized
to accept as consideration for Shares issued under the Plan the following:

                           (i) cash;

                                      A-11


                           (ii) check;

                           (iii)  surrender  of Shares or delivery of a properly
executed form of  attestation  of ownership of Shares as the  Administrator  may
require  which have a Fair Market Value on the date of surrender or  attestation
equal to the aggregate exercise price of the Shares as to which said Award shall
be exercised,  provided,  however,  that Shares  acquired  under the Plan or any
other equity  compensation  plan or agreement of the Company must have been held
by the  Grantee  for a  period  of more  than six (6)  months  (and not used for
another Award exercise by attestation during such period);

                           (iv)  with  respect  to  Options,  payment  through a
broker-dealer  sale and remittance  procedure  pursuant to which the Grantee (A)
shall provide  written  instructions to a Company  designated  brokerage firm to
effect the immediate  sale of some or all of the  purchased  Shares and remit to
the Company  sufficient funds to cover the aggregate  exercise price payable for
the purchased Shares and (B) shall provide written  directives to the Company to
deliver the  certificates  for the purchased  Shares  directly to such brokerage
firm in order to complete the sale transaction; or

                           (v)  any  combination  of the  foregoing  methods  of
payment.

                  (c) TAXES.  No Shares shall be delivered under the Plan to any
Grantee or other person until such Grantee or other person has made arrangements
acceptable to the Administrator  for the satisfaction of any non-U.S.,  federal,
state,  or local income and employment tax withholding  obligations,  including,
without  limitation,  obligations  incident  to the  receipt  of  Shares  or the
disqualifying  disposition of Shares  received on exercise of an Incentive Stock
Option.  Upon  exercise of an Award the Company  shall  withhold or collect from
Grantee an amount sufficient to satisfy such tax obligations.

         8. EXERCISE OF AWARD.

                  (a) PROCEDURE FOR EXERCISE; RIGHTS AS A STOCKHOLDER.

                           (i) Any Award granted  hereunder shall be exercisable
at such times and under such conditions as determined by the Administrator under
the terms of the Plan and specified in the Award Agreement.

                           (ii) An Award  shall be deemed to be  exercised  when
written notice of such exercise has been given to the Company in accordance with
the terms of the Award by the person  entitled  to  exercise  the Award and full
payment for the Shares with respect to which the Award is exercised,  including,
to the extent selected,  use of the broker-dealer sale and remittance  procedure
to pay the purchase price as provided in Section 7(b)(iv).

                  (b)  EXERCISE OF AWARD  FOLLOWING  TERMINATION  OF  CONTINUOUS
SERVICE.

                           (i)  An  Award  may  not  be   exercised   after  the
termination  date of such  Award  set forth in the  Award  Agreement  and may be
exercised  following the termination of a Grantee's  Continuous  Service only to
the extent provided in the Award Agreement.

                                      A-12


                           (ii) Where the Award  Agreement  permits a Grantee to
exercise an Award following the termination of the Grantee's  Continuous Service
for a specified period, the Award shall terminate to the extent not exercised on
the last day of the specified period or the last day of the original term of the
Award, whichever occurs first.

                           (iii)  Any Award  designated  as an  Incentive  Stock
Option to the extent not  exercised  within  the time  permitted  by law for the
exercise of Incentive  Stock Options  following the  termination  of a Grantee's
Continuous Service shall convert  automatically to a Non-Qualified  Stock Option
and thereafter  shall be  exercisable  as such to the extent  exercisable by its
terms for the period specified in the Award Agreement.

         9. CONDITIONS UPON ISSUANCE OF SHARES.

                  (a) Shares shall not be issued  pursuant to the exercise of an
Award  unless the  exercise of such Award and the  issuance and delivery of such
Shares  pursuant  thereto shall comply with all  Applicable  Laws,  and shall be
further  subject to the approval of counsel for the Company with respect to such
compliance.

                  (b) As a condition  to the  exercise of an Award,  the Company
may require the person  exercising  such Award to  represent  and warrant at the
time of any  such  exercise  that  the  Shares  are  being  purchased  only  for
investment and without any present  intention to sell or distribute  such Shares
if, in the opinion of counsel for the Company, such a representation is required
by any Applicable Laws.

         10. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION. Subject to any required
action by the stockholders of the Company,  the number of Shares covered by each
outstanding  Award,  and the  number of Shares  which have been  authorized  for
issuance under the Plan but as to which no Awards have yet been granted or which
have been  returned to the Plan,  the  exercise  or purchase  price of each such
outstanding Award, the maximum number of Shares with respect to which Awards may
be granted to any  Grantee in any  fiscal  year of the  Company,  as well as any
other  terms  that the  Administrator  determines  require  adjustment  shall be
proportionately  adjusted  for (i) any  increase  or  decrease  in the number of
issued Shares resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Shares, or similar transaction  affecting
the Shares,  (ii) any other  increase or decrease in the number of issued Shares
effected  without  receipt  of  consideration  by the  Company,  or (iii) as the
Administrator  may  determine  in its  discretion,  any other  transaction  with
respect to Common Stock including a corporate merger, consolidation, acquisition
of property or stock,  separation (including a spin-off or other distribution of
stock or property), reorganization, liquidation (whether partial or complete) or
any similar  transaction;  provided,  however that conversion of any convertible
securities  of the Company  shall not be deemed to have been  "effected  without
receipt of  consideration."  Such adjustment shall be made by the  Administrator
and its  determination  shall be final,  binding and  conclusive.  Except as the
Administrator  determines,  no issuance by the Company of shares of stock of any
class,  or  securities  convertible  into  shares of stock of any  class,  shall
affect,  and no  adjustment  by reason hereof shall be made with respect to, the
number or price of Shares subject to an Award.

                                      A-13


         11. CORPORATE TRANSACTIONS AND CHANGES IN CONTROL.

                  (a)  TERMINATION  OF AWARD TO EXTENT NOT ASSUMED IN  CORPORATE
TRANSACTION.  Effective upon the  consummation of a Corporate  Transaction,  all
outstanding  Awards  under the Plan shall  terminate.  However,  all such Awards
shall not  terminate  to the  extent  they are  Assumed in  connection  with the
Corporate Transaction.

                  (b) ACCELERATION OF AWARD UPON CORPORATE TRANSACTION OR CHANGE
IN CONTROL.

                      (i) CORPORATE TRANSACTION. Except as provided otherwise in
  an individual Award Agreement,  in the event of a Corporate  Transaction,  for
  the portion of each Award that is neither  Assumed nor Replaced,  such portion
  of the Award shall  automatically  become fully vested and  exercisable and be
  released  from any  repurchase or  forfeiture  rights  (other than  repurchase
  rights  exercisable  at fair  market  value) for all of the Shares at the time
  represented by such portion of the Award,  immediately  prior to the specified
  effective date of such Corporate Transaction.

                      (ii) CHANGE IN CONTROL. Except as provided otherwise in an
individual  Award  Agreement,  in the event of a Change in Control (other than a
Change in Control which also is a Corporate Transaction), each Award which is at
the time outstanding under the Plan automatically  shall become fully vested and
exercisable and be released from any repurchase or forfeiture rights (other than
repurchase  rights  exercisable at fair market value),  immediately prior to the
specified effective date of such Change in Control, for all of the Shares at the
time represented by such Award.

                  (c) EFFECT OF  ACCELERATION  ON INCENTIVE  STOCK OPTIONS.  Any
Incentive  Stock Option  accelerated  under this Section 11 in connection with a
Corporate  Transaction  or Change in  Control  shall  remain  exercisable  as an
Incentive  Stock Option  under the Code only to the extent the  $100,000  dollar
limitation  of Section  422(d) of the Code is not  exceeded.  To the extent such
dollar  limitation  is  exceeded,   the  excess  Options  shall  be  treated  as
Non-Qualified Stock Options.

         12.  EFFECTIVE DATE AND TERM OF PLAN.  The Plan shall become  effective
upon its initial approval by the stockholders of the Company.  It shall continue
in effect  for a term of ten (10) years  unless  sooner  terminated.  Subject to
Applicable  Laws,  Awards  may be  granted  under  the Plan  upon  its  becoming
effective.

         13. AMENDMENT, SUSPENSION OR TERMINATION OF THE PLAN.

                  (a) The Board may at any time amend,  suspend or terminate the
Plan;  provided,  however,  that no such  amendment  shall be made  without  the
approval of the Company's  stockholders  to the extent such approval is required
by Applicable  Laws, or if such amendment  would change any of the provisions of
Section 4(b)(vi) or this Section 13(a).

                  (b) No Award may be granted  during any suspension of the Plan
or after  termination  of the Plan.

                                      A-14


                  (c) No  suspension  or  termination  of  the  Plan  (including
termination of the Plan under Section 12 above shall adversely affect any rights
under Awards already granted to a Grantee.

         14. RESERVATION OF SHARES.

                  (a) The  Company,  during  the term of the  Plan,  will at all
times reserve and keep available such number of Shares as shall be sufficient to
satisfy the requirements of the Plan.

                  (b) The inability of the Company to obtain  authority from any
regulatory body having jurisdiction,  which authority is deemed by the Company's
counsel to be necessary to the lawful issuance and sale of any Shares hereunder,
shall relieve the Company of any liability in respect of the failure to issue or
sell  such  Shares  as to which  such  requisite  authority  shall not have been
obtained.

         15. NO EFFECT ON TERMS OF EMPLOYMENT/CONSULTING  RELATIONSHIP. The Plan
shall not  confer  upon any  Grantee  any right with  respect  to the  Grantee's
Continuous  Service,  nor shall it interfere in any way with his or her right or
the right of the  Company  or any  Related  Entity to  terminate  the  Grantee's
Continuous  Service  at any time,  with or  without  Cause,  and with or without
notice.  The  ability of the  Company or any  Related  Entity to  terminate  the
employment  of a Grantee who is  employed  at will is in no way  affected by its
determination  that the Grantee's  Continuous  Service has been  terminated  for
Cause for the purposes of this Plan.

         16.  NO  EFFECT  ON  RETIREMENT  AND  OTHER  BENEFIT  PLANS.  Except as
specifically  provided in a retirement or other benefit plan of the Company or a
Related  Entity,  Awards  shall  not be  deemed  compensation  for  purposes  of
computing benefits or contributions  under any retirement plan of the Company or
a Related Entity, and shall not affect any benefits under any other benefit plan
of any  kind  or any  benefit  plan  subsequently  instituted  under  which  the
availability or amount of benefits is related to level of compensation. The Plan
is not a  "Retirement  Plan" or  "Welfare  Plan" under the  Employee  Retirement
Income Security Act of 1974, as amended.

         17.  UNFUNDED  OBLIGATION.  Grantees  shall  have the status of general
unsecured creditors of the Company.  Any amounts payable to Grantees pursuant to
the  Plan  shall  be  unfunded  and  unsecured  obligations  for  all  purposes,
including,  without  limitation,  Title  I of  the  Employee  Retirement  Income
Security  Act of 1974,  as amended.  Neither the Company nor any Related  Entity
shall be required to segregate any monies from its general  funds,  or to create
any trusts,  or establish any special accounts with respect to such obligations.
The Company shall retain at all times  beneficial  ownership of any investments,
including trust  investments,  which the Company may make to fulfill its payment
obligations  hereunder.  Any  investments  or the creation or maintenance of any
trust or any Grantee account shall not create or constitute a trust or fiduciary
relationship between the Administrator,  the Company or any Related Entity and a
Grantee, or otherwise create any vested or beneficial interest in any Grantee or
the Grantee's  creditors in any assets of the Company or a Related  Entity.  The
Grantees  shall have no claim against the Company or any Related  Entity for any
changes in the value of any assets  that may be invested  or  reinvested  by the
Company with respect to the Plan.

         18. PLAN HISTORY.  The Plan initially became effective upon is approval
by the  stockholders  on July 21, 2004. In February  2005, the Board approved an
amendment and  restatement of the Plan in order to increase the number of shares
available for issuance  thereunder by 300,000  shares from  1,000,000  shares to
1,300,00 shares, with such amendment and restatement of the Plan to be effective
only upon approval by the stockholders of the Company.
