opportunity  for  Stockholders  to  present  questions  to  management  and to a
representative  of  the  Company's  independent  auditors.  Discussions  of  the
Company's  business at past annual meetings have generally been  interesting and
useful. We hope you will be able to attend.

         The Company's Annual Report on  Form 10-KSB/A No. 1 for  the year ended
December 28, 1997, including the financial statements, is enclosed.  Such report
and financial statements are not a part of this Proxy Statement.

completing,  signing,  dating and promptly  returning your proxy in the enclosed
envelope. PLEASE MARK YOUR PROXY CARD CAREFULLY.

         YOUR STOCK WILL BE VOTED IN ACCORDANCE WITH THE  INSTRUCTIONS  YOU HAVE
GIVEN IN YOUR PROXY.  IF YOU ARE A STOCKHOLDER  OF RECORD AND ARE PRESENT AT THE
ANNUAL  MEETING,  YOU MAY  WITHDRAW  YOUR BALLOT IN PERSON AND YOU MAY CAST YOUR

adjourned,  at the Company's  Corporate  office,  9150 Guilford Road,  Columbia,
Maryland, for the following purposes:

1.       To elect seven (7) directors to serve until the  next Annual Meeting of
         Stockholders or until their successors are duly elected and qualified;

                           TO BE HELD NOVEMBER 9, 1998

                      ------------------------------------


         The enclosed  proxy is furnished to the holders of common stock,  $0.10
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 November 9, 1998 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 October 12, 1998.

         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  approval of the 1998 Stock Option Plan;  and FOR  ratification  of
appointment of independent auditors.  The Company's Board of Directors has taken
unanimous affirmative action with respect to each of the foregoing proposals and
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 September 21,
1998  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,  notwithstanding  any subsequent  transfers of stock.  The
stock transfer books will not be closed.

Common  Stock.  Only 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,
such holders being 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 of Common Stock 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 present,  the Annual Meeting may be adjourned
until a quorum is obtained.  The  nominees to be selected as directors  named in
Proposal 1 must  receive a plurality  of the  eligible  votes cast at the Annual
Meeting  with  respect to  Proposal 1. The  approval of all other  matters to be
considered at the Annual Meeting  requires the affirmative vote of a majority of
the eligible  votes cast at the Annual Meeting on such matter.  Abstentions  and
broker  non-votes  will be  counted  only for the  purpose  of  determining  the
existence of a quorum.

                      THE BOARD OF DIRECTORS AND COMMITTEES

         The Company's  directors  generally meet quarterly.  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.  Board members not employed by the Company  receive a maximum of
$1,500 for each Board or Board  Committee  Meeting  attended.  In 1997 the Board
held seven meetings;  the entire  membership of the Board was present at all but
two  meetings  where  one  director  was  absent.   Outside  directors  received
compensation for two of seven meetings attended.

         The  Board of  Directors  has  three  standing  Committees:  the  Audit
Committee,  the  Ethics  Committee  and the  Compensation  Committee.  The Audit
Committee,  established by resolution of the Board, is vested with the following
duties  and  powers:  (1) to  recommend  to the  Board  the  independent  public
accountants  to audit the books and  records of the  Company;  (2) to review the
recommendations of the independent public accountants with respect to accounting
methods and internal controls, and to advise the Board with respect thereto; (3)
to examine the scope and extent of the audit conducted by the independent public
accountants  and to advise the Board with  respect  thereto;  and (4) such other
functions and  responsibilities  as may be assigned by the Board. Mr. A. William
Perkins and Mr. Robert W. Hicks were members of the Audit Committee and attended
all three  meetings of the Committee  held in 1997.  Ray M. Keeler  replaced Mr.
Perkins upon his  retirement in 1998.  The Audit  Committee met and reviewed all
interim statements and reports prior to issuance to shareholders and filing with
the Securities and Exchange Commission. In addition,  Directors Hicks and Keeler
have made  frequent  visits  during  1998 to meet with  Company  management  and
operating  personnel to assess and monitor  operations and report such status to
the Board.

         The Board of Directors has an established Ethics Committee. Its purpose
is to advise Essex management  of means of  ensuring that  Essex adheres  to the
highest  ethical standards  in its  operations.  A. William  Perkins and  Harold
Hanson  served on  the  Ethics Committee in 1997.  Ray  M. Keeler  replaced  Mr.
Perkins upon his retirement in 1998.

         The  Compensation  Committee  recommends  to  the  Board  of  Directors
compensation,  including incentive compensation, for principal executives of the
Company.  Membership  is comprised of outside  directors and consisted of Samuel
Hopkins until his retirement and Ray M. Keeler during 1997. Frank E. Manning was
appointed to the  Committee in November  1997.  The  Committee  was consulted on
several matters;  however, all issues concerning  compensation were discussed by
the Board as a whole.

DEFINED CONTRIBUTION RETIREMENT PLAN

     The Company has a qualified defined contribution retirement plan, the Essex
Corporation  Retirement Plan and Trust, which includes a 401(k) salary reduction
feature for its employees.  The Plan calls for a  discretionary  contribution as
determined by the Board of Directors,  and an employer matching  contribution of
up to 3% of eligible employee  compensation  under the salary reduction feature.
Discretionary  contributions are determined  annually by the Board of Directors.
No discretionary contribution was made by the Company to the Retirement Plan for
1997. The total authorized  contribution under the matching contribution feature
of the Plan was approximately  $122,500 in 1997. All employee  contributions are
100%  vested at all  times and  Company  contributions  vest  based on length of
service.  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  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.  Such awards may
be constrained by overall Company performances.  There were no awards in 1997 to
persons  employed in the  continuing  operations  of the Company.  The incentive
awards  under the  Performance  Award Plan for the  persons  referred  to in the
Summary Compensation Table are included in that Table.

EMPLOYMENT AGREEMENTS

     Since 1988,  the Company has  had an  Agreement of  Employment  with  Harry
Letaw, Jr.,  Chairman  of the  Board and  Chief Executive  Officer.  Dr. Letaw's
annual compensation was originally established  at $120,000 but  was reduced, at
his  recommendation, to  the annual  amounts shown in  the Summary  Compensation
Table.  Dr. Letaw's  annual compensation  was increased  to  $135,200  effective
October 2, 1995.  The  term  of this Agreement is  extended on  a month-to-month
basis by mutual agreement.

     The Company has an  Agreement of Employment with Frank E. Manning, Chairman
Emeritus and Member of the Essex Board of  Directors,  whereby Mr.  Manning is a
part-time  employee of the Company with duties to provide  advice and counsel to
the management of Essex. The Agreement may be terminated by either party with 60
days advance notice.  Mr. Manning also receives  reimbursement  of medical costs
not covered by Medicare.  Mr. Manning received  compensation of $5,800 in fiscal
year  1997  for  his  services  as  an  employee  of  the  Company  and  medical
reimbursement of $1,431 in 1997.

     The above agreements restrict  the individuals' rights to  compete with the
Company and prohibit misappropriation of proprietary rights of the Company, both
during and after the term of employment.

OPTIONS TO PURCHASE SECURITIES

     The Company has a 1996 Stock Option and Appreciation Rights Plan (the "1996
Plan").  The 1996  Plan as  presently  in effect  provides  for the grant of tax
qualified  Incentive  Stock  Options  ("ISOs")  and  options  that  are  not tax
qualified  ("NSOs") and Stock  Appreciation  Rights ("SARs") which rights may be
related to, but not necessarily be granted in tandem with, options granted under
the 1996 Plan.  Persons eligible to receive awards of options and SARs under the
1996 Plan include  officers,  directors,  key  employees  and other  persons who
provide  valuable  services to the  Company.  SARs entitle the holder to cash or
Company  Common Stock  measured by the increase in market value of the Company's
Common Stock from the date of grant to the date of exercise.  The exercise price
of an ISO under the 1996 Plan may not be less than the fair market  value of the
Company  stock  on the  date of  grant;  the  exercise  price  of  NSOs  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 50%
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.  The
1996 Plan reserves  300,000  shares of the Company's  Common Stock for issuance.
There are options for 260,700 shares  outstanding at prices ranging from $1.00 -
$3.00,  including  options  for 112,000  shares  held by  officers or  directors
(options for 160,125 shares are exercisable,  including exercisable options held
by officers and directors of 63,400). As of August 31, 1998, there remain 39,300
shares available for future grants of options or SARs.

     The Company had an Option and Stock Appreciation Rights Plan ("OSAR Plan ")
which expired on January 31, 1997 with no shares available for future grants. As
of August 31, 1998,  options for 657,250  shares of the  Company's  Common Stock
remain  outstanding under this Plan. Of this amount,  options for 599,820 shares
are exercisable at prices ranging from $2.50 - $3.08  including  options held by
officers and directors to purchase  545,000 shares (of which options for 504,400
shares are exercisable).

               PROPOSAL 2 -- RATIFICATION OF THE ESSEX CORPORATION
                 1998 STOCK OPTION AND APPRECIATION RIGHTS PLAN


     The Board of Directors  established the Essex Corporation 1998 Stock Option
and  Appreciation  Rights Plan (the "1998  Plan"),  which plan  provides for the
issuance of  incentive  options,  non-qualified  options and stock  appreciation
rights. Pursuant to the resolution, the Board of Directors has declared it to be
advisable and in the best interests of the Company and its Stockholders that the
Company  adopt  such  plan and has  directed  that the 1998  Plan,  as set forth
herein,  be submitted to the Stockholders of the Company for ratification at the
Annual Meeting. Stockholder ratification means that Incentive Options awarded in
accordance with the 1998 Plan will receive favorable treatment,  as noted below,
under Section 422 of the Internal Revenue Code of 1986.

     The following summary of the material provisions of the 1998 Plan set forth
herein is not  intended  to be  complete  and is  qualified  in its  entirety by
reference to the 1998 Plan,  a copy of which is attached  hereto as Exhibit A to
this Proxy Statement.

GENERAL

     The purpose of the 1998 Plan is to induce  officers,  directors,  employees
and  consultants  of the  Company  (or  any of its  subsidiaries)  who  are in a
position to contribute materially to the Company's prosperity to remain with the
Company,  to offer such persons  incentives  and rewards in recognition of their
contributions  to the  Company's  progress  and to  encourage  such  persons  to
continue to promote the best  interests of the Company.  The 1998 Plan  provides
for the grant to officers, directors, employees and consultants of stock options
which qualify as incentive stock options ("Incentive Options") under Section 422
of the Internal  Revenue Code of 1986 (the "Code"),  as well as options which do
not so qualify ("Non-Qualified Options"). In addition, stock appreciation rights
("SARs") may be granted in conjunction  with the grant of Incentive  Options and
Non-Qualified Options.

     The 1998 Plan provides for the granting of Incentive Options, Non-Qualified
Options and SARs with  respect  to, in the  aggregate,  up to 300,000  shares of
Common  Stock  (which  number is  subject  to  adjustment  in the event of stock
dividends,  stock  splits,  and other  similar  events).  To the extent  that an
Incentive Option or  Non-Qualified  Option is not exercised within the period of
exercisability  specified  therein,  it will  expire as to the then  unexercised
portion. If any Incentive Option,  Non-Qualified  Option or SAR terminates prior
to  exercise  thereof and during the  duration  of the 1998 Plan,  the shares of
Common  Stock as to which such  option or right was not  exercised  will  become
available  under the 1998 Plan for the grant of additional  options or rights to
any eligible officer,  director,  employee and consultant.  The shares of Common
Stock subject to the 1998 Plan may be made available from either  authorized but
unissued shares,  treasury shares,  or both. The 1998 Plan became effective upon
adoption by the Board of Directors,  subject to its approval by the  affirmative
vote of the  holders of a majority of the  company's  outstanding  voting  stock
entitled to vote thereon. In the event that the 1998 Plan is not approved by the
Stockholders,  the 1998 Plan shall remain in force; however, all options granted
thereunder shall automatically be deemed to be Non-Qualified Options.



                                       14

<PAGE>






     As of the date  hereof:  (a) there have been no  options or rights  granted
under  the 1998  Plan,  and (b) an  aggregate  of 57  persons  are  eligible  to
participate  in the 1998 Plan  including  53 employees  (including  12 executive
officers and  directors) of the Company  entitled to receive  Incentive  Options
under the 1998 Plan and 4 persons (all directors) who may receive Non- Qualified
Options  under the 1998 Plan.  Consultants  engaged by the Company  from time to
time are also expected to be eligible to receive Non-Qualified Options under the
1998 Plan.

ADMINISTRATION

     The 1998 Plan will be administered by: (a) the Board of Directors or (b) in
the discretion of the Board of Directors,  by a committee (the  "Committee")  of
the Board of Directors of two or more members of the Board of Directors, each of
whom is a "Non-Employee" director as such term is defined by Rule 16b-3 (as such
rule may be  amended  from time to time,  "Rule  16b- 3")  under the  Securities
Exchange Act of 1934, as amended (the "Exchange Act"). The Board of Directors or
the Committee  generally has the authority to determine the  individuals to whom
and the date on which options and rights are to be granted, the number of shares
of stock to be subject to each option and right, the exercise price of shares of
stock  subject to options  and rights,  the terms of any  vesting or  forfeiture
schedule and the other terms and provisions of each option and right.

SECTION 16(B) COMPLIANCE

     It is intended that transactions pursuant to the 1998 Plan will satisfy the
conditions  of Rule  16b-3,  as  amended,  promulgated  under  Section 16 of the
Exchange  Act.  Section  16(b) of the Exchange Act provides  that any  so-called
"short swing  profits," that is, a profit realized by an officer,  director,  or
owner of 10 percent or more of the  outstanding  securities  on a purchase and a
sale of stock within a six-month  period,  are  recoverable by the issuer of the
securities. Although the application of Section 16(b) (and the rules promulgated
thereunder)  is complex,  Rule 16b-3  generally  mitigates the impact of Section
16(b) by providing an exemption from the liability  provisions for  transactions
which satisfy the conditions of Rule 16b-3.

ELIGIBILITY AND EXTENT OF PARTICIPATION

     Incentive  Options  may be  granted  pursuant  to the  1998  Plan  only  to
employees of the Company (or any subsidiary). Non-Qualified Options and SARs may
be  granted  pursuant  to the 1998 Plan to  officers,  directors,  employees  or
consultants of the Company or any subsidiary.

     There is no minimum  number of shares of Common Stock with respect to which
an option or right may be granted.  However,  if the aggregate fair market value
of shares with respect to which Incentive  Options are exercisable for the first
time by any employee  during any calendar  year (under all stock option plans of
the  Company)  exceeds  $100,000,  such  excess  options  shall  be  treated  as
Non-Qualified  Options.  For the purpose of the foregoing  limitation,  the fair
market value of shares subject to an Incentive  Option is to be determined as of
the time the option is granted.



                                       15

<PAGE>




     The Board of Directors  or the  Committee  may  require,  as a condition of
granting  any  option or right,  that the  optionee  enter  into a stock  option
agreement which shall require, among other things, the agreement by the employee
with the  Company  that the  employee  not sell or  otherwise  dispose of shares
acquired  pursuant to the exercise of an  Incentive  Option for a minimum of two
years from the date of grant of the Incentive  Option and one year from the date
of transfer of the Common Stock, absent the written approval,  consent or waiver
of the Board of Directors or Committee.

PURCHASE PRICE AND EXERCISE OF OPTIONS

     The price at which  shares  of Common  Stock  covered  by an option  may be
purchased  shall be  determined  by the  Board of  Directors  or the  Committee;
however,  the purchase price of shares of Common Stock issuable upon exercise of
an  Incentive  Option must not be less than 100 percent of the fair market value
of such shares on the date the  Incentive  Option is granted.  Any cash proceeds
received  by the  Company  from the  exercise  of the  options  will be used for
general corporate purposes.

EXPIRATION AND TRANSFER OF OPTIONS

     The Board of Directors or the Committee has the sole  discretion to fix the
period within which any Incentive or Non-Qualified Option may be exercised.  Any
Incentive Option granted under the 1998 Plan to a 10 percent or less stockholder
and any  Non-Qualified  Option shall be exercised  during a period not more than
ten years from the date of grant and any Incentive  Option  granted to a greater
than 10 percent  stockholder  shall be exercised within five years from the date
of grant. No Incentive  Options may be granted under the 1998 Plan more than ten
years after the date of adoption of the 1998 Plan.

     Options granted under the 1998 Plan are not transferable except upon death.
Incentive  options  generally  may be exercised  only while the option holder is
employed by the Company, or in some cases, within three months of termination of
employment.  In the event of disability of an option holder,  incentive  options
may be  exercised  to the extent of the  accrued  right to  purchase  the option
within one year of termination of employment due to disability.  In the event of
death  of an  option  holder,  incentive  options  may  be  exercised  prior  to
expiration of the option  within three years after the date of death,  whichever
period  of time is  shorter.  In the  event of  retirement  of an  optionholder,
options may be exercised at any time within the remaining term of such option.

     Upon a  reorganization,  merger or consolidation of the Company as a result
of which the  outstanding  Common Stock is changed into or exchanged for cash or
property  or  securities  not  of  the  Company's  issue,  or  upon  a  sale  of
substantially all the property of the Company,  the 1998 Plan will terminate and
all outstanding  options previously  granted thereunder shall terminate,  unless
provision is made in connection with such transaction for the continuance of the
1998 Plan or for the assumption of options therefore  granted.  If the 1998 Plan
and unexercised  options are to terminate pursuant to such transaction,  persons
owning any unexercised portions of options then outstanding will have the right,
prior to the  consummation  of the  transaction,  to  exercise  the  unexercised
portions of their options,  including the portions  thereof which would, but for
such transaction, not yet be exercisable.


                                       16

FEDERAL INCOME TAX CONSIDERATIONS

     In case of Incentive Options, no taxable gain will be realized by an option
holder  upon  grant or  exercise  of the  option,  and the  Company  will not be
entitled to a tax deduction at the time any such option is granted or exercised.
However,  the excess of the fair  market  value of any stock  received  over the
option price will  constitute  an adjustment  in computing  alternative  minimum
taxable  income at the time of the transfer of stock pursuant to the exercise of
the  option,  or if  later,  at the  earlier  of the  time  that  the  stock  is
transferable or is not subject to a substantial risk of forfeiture.

     The  treatment  for federal  income tax purposes of  Non-Qualified  Options
depends on whether the option has a readily  ascertainable  fair market value at
the time it is granted.  Because  the  Non-Qualified  Options  are not  actively
traded on an established  market and because it is likely that the Non-Qualified
Options  will be  nontransferable  by the  optionee  or will not be  immediately
exercisable,  it is  expected  that the  Non-Qualified  Options  will not have a
readily ascertainable fair market value. If a Non-Qualified Option does not have
a readily  ascertainable fair market value at the time of the grant, there is no
taxable event at grant;  rather,  the excess of (i) the fair market value of the
Common Stock on the date it is acquired  pursuant to exercise of the option over
(ii) the exercise  price,  plus the amount,  if any, paid for the option must be
included  in the  optionee's  gross  income at the time of the  receipt of stock
pursuant to exercise of the option, or if later, at the earlier of the time that
the stock is transferable or is not subject to a substantial risk of forfeiture.
If stock  received  pursuant to the  exercise of a  Non-Qualified  Option is not
taxable  at  receipt  because  the stock is  nontransferable  and  subject  to a
substantial risk of forfeiture,  the optionee may nevertheless  elect to include
such amount in gross  income when the stock is received  pursuant to exercise of
the option.

     Under Section 280G of the Code,  certain  persons who receive  compensation
payments in connection with a change in control of a company may be subject to a
20 percent  excise tax and the issuer may lose its tax deduction with respect to
such  payments.  These rules may apply to options and rights  granted  under the
1998 Plan. The  determination of the application of these rules will depend upon
a number  of  factual  matters  not  determinable  at this  time.  It  should be
realized,  however,  that these  rules may affect the  ability of the Company to
secure a tax deduction on the exercise of certain  Non-Qualified Options granted
under the 1998 Plan.

     The tax consequences  summarized above may change in the event of amendment
to the Code or the regulations adopted thereunder.

EXERCISE OF OPTIONS; SARS

     Generally,  an option will be  exercised by the tender in cash of the total
exercise price for the shares of stock which the option is being exercised.  The
Board of Directors or the Committee  may,  however permit an optionee to pay all
or a portion of the exercise price by delivering to the Company shares of Common
Stock  having  an  aggregate  fair  market  value at least  equal to such  total
exercise  price.  An option may also be  exercised by tender to the Company of a
written notice of exercise together with advice of the delivery of an order to a
broker  to sell  part or all of the  shares  of  Common  Stock  subject  to such
exercise  notice  and an  irrevocable  order to such  broker to  deliver  to the
Company  sufficient  proceeds  from the sale of such shares to pay the  exercise
price and any withholding taxes (a "cashless exercise") provided

                                       17

<PAGE>



all  documentation  and  procedures  are approved in advance by the Board or the
Committee.  The  Company  has the  authority  under the 1998 Plan to assist  any
employee of the Company  with the  payment of the  purchase  price of the Common
Stock by lending the amount of the  purchase  price to the  employee,  on terms,
including  rate of interest and security for the loan, as the Board of Directors
shall authorize.

     The Board of Directors or the Committee may, in its discretion, at any time
prior to the exercise of any option,  grant in  connection  with such option the
right to  surrender  part or all of such  option  to the  extent  the  option is
exercisable,  and receive an amount  (payable in cash,  shares of the  Company's
Common Stock or  combination  thereof as determined by the Board of Directors or
the Committee) equal to the difference between the then fair market value of the
shares   issuable  upon  the  exercise  of  the  option  (or  portions   thereof
surrendered)   and  the  exercise  price  of  the  option  or  portion   thereof
surrendered.

AMENDMENTS TO THE 1998 PLAN

     The Board of Directors may at any time terminate the 1998 Plan or make such
arrangements  thereto as it deems  advisable  and in the best  interests  of the
Company,  without action on the part of the Company's stockholders,  unless such
approval  is required  pursuant  to Section 422 of the Code or other  federal or
state law.  Such  amendments  may include,  without  limitation,  changes in the
number of shares  reserved for issuance  under the plan, the class or classes of
individuals eligible to participate therein and the manner of administration and
duration of the plan.

     THE BOARD OF DIRECTORS  UNANIMOUSLY  RECOMMENDS A VOTE FOR  RATIFICATION OF
THE ESSEX  CORPORATION  1998 STOCK OPTION AND APPRECIATION  RIGHTS PLAN.  UNLESS
MARKED TO THE  CONTRARY,  SHARES  OF COMMON  STOCK  REPRESENTED  BY PROXY  CARDS
RECEIVED FROM STOCKHOLDERS WILL BE VOTED IN FAVOR OF PROPOSAL 2.


                PROPOSAL 3 -- RATIFICATION OF THE APPOINTMENT OF
                              INDEPENDENT AUDITORS

     The Board of Directors  has, upon  recommendation  of the Audit  Committee,
selected Stegman & Company as independent auditors of the Company for the fiscal
year ending  December 27, 1998,  and has further  directed that the selection of
such auditors be submitted for  ratification  by the  stockholders at the Annual
Meeting. Effective June 22, 1998, Stegman & Company replaced Arthur Andersen LLP
as the  Company's  principal  accountants.  Arthur  Andersen  LLP had  been  the
Company's auditors since 1992.

     The Company had no  disagreement  with Arthur Andersen LLP on any matter of
accounting  principles or practices,  financial statement  disclosure,  internal
controls,  or auditing scope or procedure,  in connection with the audits of the
1995 or 1996 fiscal  years or  subsequent  to December 29, 1996 through June 22,
1998, the date of dismissal.  The Company's financial statements for each of the
1995 and 1996 fiscal years did not contain an adverse  opinion or  disclaimer of
opinion,  and were not  qualified as to  uncertainty,  audit scope or accounting
principles.


                                       18

<PAGE>



     The decision to change accountants was recommended unanimously by the Audit
Committee of the Company's Board of Directors.

     Stegman & Company  representatives will be present at the Annual Meeting to
respond to appropriate questions.

     THE BOARD OF  DIRECTORS  RECOMMENDS  A VOTE FOR APPROVAL OF THE PROPOSAL TO
RATIFY  THE  APPOINTMENT  OF  INDEPENDENT  AUDITORS  AND,  UNLESS  MARKED TO THE
CONTRARY,  PROXIES  RECEIVED  FROM  STOCKHOLDERS  WILL BE VOTED IN FAVOR OF SUCH
RATIFICATION.


                                  OTHER MATTERS

     The  Company  knows of no other  matters  to be  brought  before the Annual
Meeting.  If any other matter  requiring a vote of the  Stockholders is properly
brought before the Annual Meeting,  it is the intention of the persons appointed
as proxies to vote with respect to any such matter in accordance with their best
judgment.

     It is important that proxies be returned promptly. Stockholders, whether or
not they expect to attend the Annual  Meeting in person,  are urged to complete,
sign and return the accompanying  proxy in the enclosed  envelope which requires
no postage if mailed in the United States.


                STOCKHOLDER PROPOSALS FOR THE 1999 ANNUAL MEETING

     Any  proposal  which a  Stockholder  wishes to have  presented  at the next
Annual Meeting of Stockholders,  expected to be held during September 1999, must
be  received  at the office of the  Company  at 9150  Guilford  Road,  Columbia,
Maryland  21046-1891  no later than March 31, 1999.  In order for a  Stockholder
proposal  submitted  outside  Rule 14a-8 to be  considered  "timely"  within the
meaning of Rule  14a-4(c),  such  proposals  must be  received by the Company no
later than August 28, 1999.

prosperity  to remain with the  Company,  to offer said persons  incentives  and

This 1998 Plan  provides  for the grant of options to purchase  shares of common
stock of the  Company,  par value  $.10 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
employees, as well as options which do not so qualify ("Non-Qualified  Options")
to be issued to persons or  consultants,  including those who are not employees.
This 1998 Plan also provides for grants of stock appreciation rights ("SARs") in
connection with the grant of options under this 1998 Plan. Incentive Options and
Non-Qualified  Options  may  be  collectively  referred  to  hereinafter  as the
"Options" as the context may require.

         Section  1.3. All options and other  rights  previously  granted by the
Company under any other plan previously adopted by the Company shall continue to
be governed by such plan.  All Options  granted  hereunder  on or after the date
that this 1998 Plan has been  approved  and  adopted by the  Company's  board of
directors  (the  "Board  of  Directors")  shall be  governed  by the  terms  and
conditions  of this  1998 Plan  unless  the  terms of such  Option  specifically
indicate that it is not to be so governed.

                                   ARTICLE II
                                 ADMINISTRATION

         Section 2.1. All  determinations  under this 1998 Plan  concerning  the
selection  of persons  eligible to receive  awards under this 1998 Plan and with
respect to the timing, pricing and amount of an award under this 1998 Plan shall
be made by the  administrator  (the  "Administrator")  of this  1998  Plan.  The
Administrator  shall  be  either:  (a)  the  Board  of  Directors  or (b) in the
discretion  of the Board of Directors by a committee  (the  "Committee")  of the
Board of  Directors of two or more  members of the Board of  Directors,  each of
whom is a "Non-Employee director" as such term is defined by Rule 16b-3 (as such
rule may be  amended  from time to time,  "Rule  16b-3")  under  the  Securities
Exchange Act of 1934, as amended (the "Exchange  Act"). In such case, a majority
of the total number of members of the Committee shall be necessary to constitute
a quorum;  and (i) the  affirmative  act of a majority of the members present at
any meeting at which a quorum is present,  or (ii) the  approval in writing by a
majority of the members of the Committee shall be necessary to constitute action
by the Committee.

         With  respect to persons  subject  to Section 16 of the  Exchange  Act,
transactions  under this 1998 Plan are  intended to comply  with all  applicable
conditions of Rule 16b-3 or its successors under the Exchange Act. To the extent
that any provision of this 1998 Plan or action by the Administrator  fails to so
comply,  it shall be deemed to be null and void, to the extent  permitted by law
and deemed advisable by the Administrator.

         Section 2.2.  The  provisions  of this 1998 Plan  relating to Incentive
Options are  intended to comply in every  respect  with  Section 422 of the Code
("Section 422") and the regulations  promulgated  thereunder.  In the event that
any future statute or regulation  shall modify Section 422, this 1998 Plan shall
be deemed to  incorporate  by  reference  such  modification.  Any stock  option
agreement  relating to the grant of any Incentive  Option  pursuant to this 1998
Plan, which option is outstanding and unexercised at the time that any modifying
statute or regulation becomes effective,  shall also be deemed to incorporate by
reference such modification, and no notice of such modification need be given to
the Optionee (as hereinafter defined). Any stock option agreement relating to an
Incentive  Option shall provide that the Optionee (as hereinafter  defined) hold
the stock received upon exercise of

                                        i

<PAGE>



such  Incentive  Option for a minimum of two years from the date of grant of the
Incentive  Option  and one  year  from the date of  exercise  of such  Incentive
Option, absent the written approval, consent or waiver of the Administrator.

         Section  2.3.  If any  provision  of this  1998 Plan is  determined  to
disqualify the shares of Common Stock  purchasable upon exercise of an Incentive
Option  granted under this 1998 Plan from the special tax treatment  provided by
Section 422,  such  provision  shall be deemed to  incorporate  by reference the
modification  required  to  qualify  such  shares of  Common  Stock for said tax
treatment.

         Section 2.4. The Company  shall grant  Options  under this 1998 Plan in
accordance  with  determinations  made  by  the  Administrator  pursuant  to the
provisions  of this 1998 Plan.  All Options  granted  pursuant to this 1998 Plan
shall be clearly identified as Incentive Options or Non-Qualified  Options.  The
Administrator may from time to time adopt (and thereafter amend or rescind) such
rules and  regulations  for  carrying out this 1998 Plan and take such action in
the  administration  of this 1998 Plan,  not  inconsistent  with the  provisions
hereof,  as it shall deem  proper.  The Board of  Directors  or,  subject to the
supervision  of the Board of Directors,  the  Committee,  as the  Administrator,
shall have plenary  discretion,  subject to the express  provisions of this 1998
Plan, to determine which officers, directors, employees and consultants shall be
granted Options,  the number of shares subject to each Option, the time or times
when an Option may be exercised  (whether in whole or in installments),  whether
Rights under  Section 7.6 hereof shall be granted,  the terms and  provisions of
the respective option  agreements (which need not be identical),  including such
terms  and  provisions  which  may be  amended  from  time to time as  shall  be
required, in the judgment of the Administrator,  to conform to any change in any
law or regulation applicable hereto, and to make all other determinations deemed
necessary  or  advisable  for  the   administration   of  this  1998  Plan.  The
interpretation  and  construction  of any  provision  of this  1998  Plan by the
Administrator  (unless otherwise  determined by the Board of Directors) shall be
final, conclusive and binding upon all persons.

         Section  2.5.  No member of the  Administrator  shall be liable for any
action or  determination  made in good faith with respect to  administration  of
this 1998 Plan or the Options granted  hereunder.  A member of the Administrator
shall be indemnified by the Company,  pursuant to the Company's bylaws,  for any
expenses,  judgments  or other  costs  incurred  as a result of a lawsuit  filed
against such member claiming any rights or remedies arising out of such member's
participation in the administration of this 1998 Plan.

                                   ARTICLE III
                      TOTAL NUMBER OF SHARES TO BE OPTIONED

         Section  3.1.  There shall be reserved  for  issuance or transfer  upon
exercise  of  Options  to be  granted  from time to time under this 1998 Plan an
aggregate  of  300,000  shares  of  Common  Stock  of the  Company  (subject  to
adjustment as provided in Article VIII hereof).  The shares issued upon exercise
of any  Options  granted  under  this 1998  Plan may be  shares of Common  Stock
previously  issued and  reacquired by the Company at any time or authorized  but
unissued shares of Common Stock, as the Board of Directors from time to time may
determine.

         Section 3.2. In the event that any Options  outstanding under this 1998
Plan for any reason expire or are  terminated  without  having been exercised in
full or shares of Common Stock subject to Options are surrendered in whole or in
part pursuant to Rights  granted under Section 7.6 hereof  (except to the extent
that  shares of Common  Stock are  issued as payment to the holder of the Option
upon such  surrender)  the  unpurchased  shares of Common Stock  subject to such
Option and any such  surrendered  shares of Common  Stock may again be available
for transfer under this 1998 Plan.

         Section 3.3. No Options shall be granted  pursuant to this 1998 Plan to
any  Optionee  after  the tenth  anniversary  of the date that this 1998 Plan is
adopted by the Board of Directors.

                                   ARTICLE IV
                                   ELIGIBILITY

         Section 4.1. Non-Qualified Options may be granted pursuant to this 1998
Plan to officers, directors, employees and consultants of the Company (or any of
its subsidiaries)  selected by the  Administrator,  and Incentive Options may be
granted  pursuant to this 1998 Plan only to  employees  (including  officers and
directors who are also  employees)  of the Company (or any of its  subsidiaries)
selected by the  Administrator.  Persons granted  Options  pursuant to this 1998
Plan are referred to herein as  "Optionees."  For purposes of determining who is
an employee

                                       ii

with respect to eligibility for Incentive Options, Section 422 shall govern. The
Administrator  may determine (in its sole  discretion) that any person who would
otherwise be eligible to be granted Options shall, nonetheless, be ineligible to
receive any award under this 1998 Plan.

         Section 4.2. The Administrator  will (in its discretion)  determine the
persons  to be  granted  Options,  the time or times at which  Options  shall be
granted,  the number of shares of Common Stock subject to each Option, the terms
of a vesting or  forfeiture  schedule,  if any, the type of Option  issued,  the
period during which such Options may be  exercised,  the manner in which Options
may be exercised and all other terms and  conditions  of the Options;  PROVIDED,
HOWEVER,  no Option will be granted which has terms or  conditions  inconsistent
with those stated in Articles V and VI hereof.  Relevant  factors in making such
determinations  may include the value of the services rendered by the respective
Optionee,  his or her present and potential  contributions  to the Company,  and
such other factors  which are deemed  relevant in  accomplishing  the purpose of
this 1998 Plan.

                                    ARTICLE V
                         TERMS AND CONDITIONS OF OPTIONS

         Section  5.1.  Each  Option  granted  under  this  1998  Plan  shall be
evidenced  by a stock  option  certificate  and  agreement  (the  "Stock  Option
Certificate and  Agreement") in a form consistent with this 1998 Plan,  provided
that the following terms and conditions shall apply:

         (a) The price at which each share of Common Stock  covered by an Option
may be  purchased  shall  be set  forth  in the  Stock  Option  Certificate  and
Agreement and shall be determined by the Administrator, provided that the option
price for any Incentive Option shall not be less than the "fair market value" of
the shares of Common Stock at the time of grant  determined in  accordance  with
Section 5.1(b) below.  Notwithstanding the foregoing,  if an Incentive Option to
purchase  shares of Common  Stock is  granted  pursuant  to this 1998 Plan to an
Optionee who, on the date of the grant,  directly or  indirectly  owns more than
ten percent  (10%) of the voting  power of all  classes of capital  stock of the
Company (or its parent or subsidiary),  not including the shares of Common Stock
obtainable  upon  exercise of the Option,  the  minimum  exercise  price of such
Option shall be not less than one hundred ten percent (110%) of the "fair market
value"  of the  shares  of  Common  Stock  on the date of  grant  determined  in
accordance with Section 5.1(b) below.

         (b) The "fair market value" shall be  determined by the  Administrator,
which  determination  shall  be  binding  upon  the  Company  and its  officers,
directors, employees and consultants. The determination of the fair market value
shall be based upon the  following:  (i) if the  shares of Common  Stock are not
listed and traded upon a recognized  securities  exchange and there is no report
of stock  prices  with  respect to the  shares of Common  Stock  published  by a
recognized  stock quotation  service,  on the basis of the recent  purchases and
sales of the shares of Common Stock in arms-length transactions;  or (ii) if the
shares  of  Common  Stock  are not then  listed  and  traded  upon a  recognized
securities  exchange or quoted on the NASDAQ Stock Market, and there are reports
of stock prices by a recognized  quotation  service,  upon the basis of the last
reported  sale or  transaction  price  of such  stock  on the  date of  grant as
reported by a recognized  quotation  service,  or, if there is no last  reported
sale or  transaction  price on that day,  then upon the basis of the mean of the
last reported closing bid and closing asked prices for such stock on that day or
on the date nearest  preceding  that day; or (iii) if the shares of Common Stock
shall then be listed and traded upon a recognized  securities exchange or quoted
on the  NASDAQ  Stock  Market,  upon  the  basis of the  last  reported  sale or
transaction price at which shares of Common Stock were traded on such recognized
securities  exchange on the date of grant or, if the shares of Common Stock were
not traded on such date, upon the basis of the last reported sale or transaction
price on the date nearest  preceding  that date.  The  Administrator  shall also
consider such other  factors  relating to the fair market value of the shares of
Common Stock as it shall deem appropriate.

         (c) For the purpose of  determining  whether an Optionee owns more than
ten percent (10%) of the voting power of all classes of stock of the Company, an
Optionee  is  considered  to own  those  shares  which  are  owned  directly  or
indirectly  through  brothers  and sisters  (including  half-blooded  siblings),
spouse,  ancestors and lineal descendants;  and proportionately as a shareholder
of a corporation, a partner of a partnership, and/or a beneficiary of a trust or
an estate that owns shares of the Company.

         (d)   Notwithstanding  any  other  provision  of  this  1998  Plan,  in
accordance with the provisions of Section 422(d) of the Code, to the extent that
the aggregate fair market value (determined at the time the Option

                                       iii

<PAGE>



is granted) of the shares of Common  Stock of the Company  with respect to which
Incentive Options (without  reference to this provision) are exercisable for the
first time by any individual in any calendar year under any and all stock option
plans of the  Company,  its  subsidiary  corporations  and its  parent  (if any)
exceeds $100,000, such Options shall be treated as Non-Qualified Options.

         (e) An Optionee may, in the Administrator's discretion, be granted more
than one Incentive  Option or  Non-Qualified  Option during the duration of this
1998  Plan,  and may be  issued  a  combination  of  Non-Qualified  Options  and
Incentive  Options;  PROVIDED,  HOWEVER,  that non-employees are not eligible to
receive Incentive Options.

         (f) The duration of any Option and any Right  related  thereto shall be
within the sole discretion of the  Administrator;  PROVIDED,  HOWEVER,  that any
Incentive  Option  granted to a ten  percent  (10%) or less  stockholder  or any
Non-Qualified  Option shall, by its terms,  be exercised  within ten years after
the date the Option is granted  and any  Incentive  Option  granted to a greater
than ten percent (10%) stockholder shall, by its terms, be exercised within five
years after the date the Option is granted.

         (g) An Option and any Right related  thereto shall not be  transferable
by the Optionee other than by will, or by the laws of descent and  distribution.
An Option may be exercised during the Optionee's lifetime only by the Optionee.

         (h) The  Administrator  may impose such other or further  conditions on
any transaction under the 1998 Plan, including without limitation,  the grant or
award of any Option or the exercise or other disposition  thereof, as it, in its
discretion,  may deem necessary or advisable in order to exempt the  transaction
from Section 16(b) of the Exchange Act,  including without  limitation  thereto,
the approval or  ratification  of the transaction by shareholders or a six-month
restriction  on  disposition  of the Option or the Common  Stock  issuable  upon
exercise thereof.

                                   ARTICLE VI
                        EMPLOYMENT OR SERVICE OF OPTIONEE

         Section 6.1. If the  employment or service of an Optionee is terminated
for cause,  the option rights of such Optionee,  both accrued and future,  under
any  then   outstanding   Non-Qualified  or  Incentive  Option  shall  terminate
immediately.  "Cause"  shall mean  incompetence  in the  performance  of duties,
disloyalty, dishonesty, theft, embezzlement, unauthorized disclosure of patents,
processes  or trade  secrets of the  Company,  individually  or as an  employee,
partner, associate,  officer or director of any organization.  The determination
of the  existence  and the proof of "cause"  shall be made by the  Administrator
and, subject to the review of any determination made by the Administrator,  such
determination shall be binding on the Optionee and the Company.

         Section 6.2. If the employment or service of the Optionee is terminated
by either the  Optionee  or the  Company  for any  reason  other than for cause,
death, retirement or for disability, as defined in Section 22(e)(3) of the Code,
the option rights of such Optionee under any then  outstanding  Incentive Option
shall,  subject to the provisions of Section  5.1(h)  hereof,  be exercisable by
such Optionee at any time prior to the  expiration of the Option or within three
months after the date of such termination,  whichever period of time is shorter,
but only to the extent of the accrued  right to exercise  the Option at the date
of such termination.

         Section  6.3.  In the case of an  Optionee  who  becomes  disabled,  as
defined by Section  22(e)(3)  of the Code,  the option  rights of such  Optionee
under any then outstanding  Incentive Option shall, subject to the provisions of
Section 5.1(h) hereof,  be exercisable by such Optionee at any time prior to the
expiration  of the Option or within one year  after the date of  termination  of
employment or service due to  disability,  whichever  period of time is shorter,
but only to the extent of the accrued  right to exercise  the Option at the date
of such termination.

         Section  6.4.  In the event of the  death of an  Optionee,  the  option
rights of such Optionee  under any then  outstanding  Incentive  Option shall be
exercisable by the person or persons to whom these rights pass by will or by the
laws of descent and  distribution,  at any time prior to the  expiration  of the
Option or within three years after the date of death,  whichever  period of time
is shorter,  but only to the extent of the accrued  right to exercise the Option
at the date of death.  If a person or estate  acquires  the right to exercise an
Incentive  Option by bequest  or  inheritance,  the  Administrator  may  require
reasonable  evidence as to the  ownership of such  Option,  and may require such
consents  and  releases  of taxing  authorities  as the  Administrator  may deem
advisable.


                                       iv

<PAGE>



         Section  6.5. If an Optionee to whom an Option has been  granted  under
this 1998 Plan retires from his employment or service with the Company or any of
the  Subsidiaries  under a  retirement  plan or  policy of the  Company  and its
Subsidiaries  or at his or her  normal  retirement  date  or  earlier  with  the
approval  or consent of the  Company or such  Subsidiary,  or as a result of the
Disability  as  defined in  Section  22(e)(3)  of the Code,  such  Option  shall
continue  to be  exercisable  in whole or in part,  to the extent not  therefore
exercised,  by the Optionee to whom granted in the manner set forth in this 1998
Plan, at any time within the remaining term of such Option.

         Section 6.6. The  Administrator  may also provide that an employee must
be  continuously  employed  by the  Company  for  such  period  of  time  as the
Administrator,  in its discretion,  deems advisable before the right to exercise
any portion of an Option granted to such employee will accrue,  and may also set
such other  targets,  restrictions  or other terms relating to the employment of
the Optionee which targets, restrictions, or terms must be fulfilled or complied
with,  as the case may be,  prior to the  exercise  of any  portion of an Option
granted to any employee.

         Section   6.7.   Except  in  the  event  of   termination   for  cause,
Non-Qualified Options shall be exercisable during such term as determined at the
time of grant by the Administrator.

         Section 6.8. Options granted under this 1998 Plan shall not be affected
by any change of duties or position,  so long as the  Optionee  continues in the
service of the Company.

         Section  6.9.  Nothing  contained  in this 1998 Plan,  or in any Option
granted  pursuant to this 1998 Plan,  shall  confer upon any  Optionee any right
with  respect  to  continuance  of  employment  or service  by the  Company  nor
interfere in any way with the right of the Company to terminate  the  Optionee's
employment or service or change the Optionee's compensation at any time.

                                   ARTICLE VII
                               PURCHASE OF SHARES

         Section 7.1. Except as provided in this Article VII, an Option shall be
exercised by tender to the Company of the full  exercise  price of the shares of
Common Stock with respect to which the Option is exercised and written notice of
the exercise.  The right to purchase  shares of Common Stock shall be cumulative
so that, once the right to purchase any shares of Common Stock has accrued, such
shares or any part  thereof may be purchased  at any time  thereafter  until the
expiration or termination of the Option.  A partial  exercise of an Option shall
not affect the right of the  Optionee to exercise  the Option from time to time,
in  accordance  with this 1998  Plan,  as to the  remaining  number of shares of
Common Stock subject to the Option. The purchase price of the shares shall be in
United   States   dollars,   payable  in  cash  or  by  certified   bank  check.
Notwithstanding  the  foregoing,  in lieu of cash,  an  Optionee  may,  with the
approval of the  Administrator,  exercise  his or her Option by tendering to the
Company  shares of Common Stock of the Company owned by him or her and having an
aggregate fair market value at least equal to the full exercise price.  The fair
market value of any shares of Common Stock so surrendered shall be determined by
the Administrator in accordance with Section 5.1(b) hereof.

         Section 7.2.  Except as provided in Article VI above, an Option may not
be exercised  unless the holder thereof is an officer,  director,  employee,  or
consultant of the Company at the time of exercise.

         Section  7.3.  No  Optionee,  or  Optionee's  executor,  administrator,
legatee, or distributee or other permitted  transferee,  shall be deemed to be a
holder of any  shares of  Common  Stock  subject  to an Option  for any  purpose
whatsoever  unless and until a stock certificate or certificates for such shares
are issued to such person under the terms of this 1998 Plan. No adjustment shall
be made for dividends (ordinary or extraordinary, whether in cash, securities or
other  property) or  distributions  or other rights for which the record date is
prior to the date such  stock  certificate  is  issued,  except as  provided  in
Article VIII hereof.

         Section 7.4. If: (i) the listing,  registration or qualification of the
Options issued  hereunder,  or of any securities  issuable upon exercise of such
Options (the "Subject  Securities")  upon any  securities  exchange or quotation
system  or under  federal  or state law is  necessary  as a  condition  of or in
connection with the issuance or exercise of the Options,  or (ii) the consent or
approval of any  governmental  regulatory body is necessary as a condition of or
in  connection  with the issuance or exercise of the Options,  the Company shall
not be obligated to deliver the certificates representing the Subject Securities
or to accept or to recognize an Option exercise unless and until such

                                        v

<PAGE>



listing,  registration,  qualification,  consent  or  approval  shall  have been
effected  or  obtained.  The  Company  will take  reasonable  action to so list,
register, or qualify the Options and the Subject Securities, or effect or obtain
such consent or approval, so as to allow for their issuance.

         Section 7.5. An Optionee may be required to represent to the Company as
a condition of his or her exercise of Options  issued under this 1998 Plan that:
(i) the Subject Securities acquired upon exercise of his or her Option are being
acquired  by him or her for  investment  purposes  only  and not  with a view to
distribution or resale,  unless counsel for the Company is then of the view that
such a representation  is not necessary and is not required under the Securities
Act of 1933, as amended (the "Securities Act"), or any other applicable statute,
law,  regulation or rule;  and (ii) that the Optionee  shall make no exercise or
disposition of an Option or of the Subject  Securities in  contravention  of the
Securities  Act,  the  Exchange  Act or the  rules and  regulations  thereunder.
Optionees may also be required to provide (as a condition  precedent to exercise
of an Option) such  documentation as may be reasonably  requested by the Company
to assure  compliance  with  applicable law and the terms and conditions of this
1996 Plan and the subject Option.

         Section  7.6.  The  Administrator  may,  in its  discretion,  grant  in
connection with any Option, at any time prior to the exercise thereof, the right
(previously defined as an "SAR" or collectively, the "SARs") to surrender all or
part of the Option to the extent that such Option is exercisable  and receive in
exchange an amount  (payable in cash,  shares of Common Stock valued at the then
fair market value, or a combination  thereof as determined by the Administrator)
equal to the difference (the "Spread") between the then fair market value of the
shares of Common  Stock  issuable  upon the  exercise of the Option (or portions
thereof  surrendered)  and the option  price  payable  upon the  exercise of the
Option (or portions thereof surrendered). Such SARs may be included in an Option
only under the following conditions:  (a) the SARs will expire no later than the
expiration of the  underlying  Option;  (b) the SARs may be for no more than one
hundred percent (100%) of the Spread;  (c) the SARs are  transferable  only when
the underlying  Option is transferable  and under the same  conditions;  (d) the
SARs may be  exercised  only  when  the  underlying  Option  is  eligible  to be
exercised;  and (e) the SARs may be exercised  only when the Spread is positive,
i.e.,  when the market  price of the stock  subject to the  Option  exceeds  the
exercise price of the Option.

         Section  7.7. An Option may also be  exercised by tender to the Company
of a written notice of exercise together with advice of the delivery of an order
to a broker to sell part or all of the  shares of Common  Stock  subject to such
exercise  notice  and an  irrevocable  order to such  broker to  deliver  to the
Company (or its transfer agent) sufficient proceeds from the sale of such shares
to pay the exercise  price and any  withholding  taxes.  All  documentation  and
procedures to be followed in connection with such a "cashless exercise" shall be
approved in advance by the Administrator.

                                  ARTICLE VIII
                    CHANGE IN NUMBER OF OUTSTANDING SHARES OF
                    STOCK, ADJUSTMENTS, REORGANIZATIONS, ETC.

         Section 8.1. In the event that the  outstanding  shares of Common Stock
of the Company are hereafter increased or decreased or changed into or exchanged
for a different  number of shares or kind of shares or other  securities  of the
Company  or  of  another  corporation  by  reason  of  reorganization,   merger,
consolidation,  recapitalization,  reclassification, stock split, combination of
shares, or a dividend payable in capital stock,  appropriate adjustment shall be
made by the  Administrator  in the number and kind of shares for the purchase of
which Options may be granted under this 1998 Plan,  including the maximum number
that may be granted to any one person. In addition, the Administrator shall make
appropriate adjustments in the number and kind of shares as to which outstanding
Options, or portions thereof then unexercised,  shall be exercisable, to the end
that the  Optionee's  proportionate  interest  shall be maintained as before the
occurrence  to the  unexercised  portion of the Option and with a  corresponding
adjustment  in the  option  price per  share.  Any such  adjustment  made by the
Administrator shall be conclusive.

         Section  8.2.  The grant of an Option  pursuant to this 1998 Plan shall
not  affect in any way the right or power of the  Company  to make  adjustments,
reclassifications,  reorganizations  or  changes  of  its  capital  or  business
structure or to merge or to  consolidate  or to dissolve,  liquidate or sell, or
transfer all or any part of its business or assets.

         Section 8.3. Upon the  dissolution or  liquidation  of the Company,  or
upon a  reorganization,  merger or  consolidation  of the Company as a result of
which the outstanding  securities of the class then subject to Options hereunder
are changed  into or  exchanged  for cash or property or  securities  not of the
Company's issue, or upon a sale of substantially all the property of the Company
to an association, person, party, corporation,  partnership, or control group as
that term is construed  for purposes of the Exchange  Act,  this 1998 Plan shall
terminate,  and all  outstanding  Options  theretofore  granted  hereunder shall
terminate,  unless  provision  be  made  in  writing  in  connection  with  such
transaction  for the  continuance of this 1998 Plan and/or for the assumption of
Options  theretofore  granted,  or the  substitution for such Options of options
covering  the  stock of a  successor  employer  corporation,  or a  parent  or a
subsidiary  thereof,  with appropriate  adjustments as to the number and kind of
shares and prices, in which event this 1998 Plan and options theretofore granted
shall continue in the manner and under the terms so provided.  If this 1998 Plan
and unexercised Options shall terminate pursuant to the foregoing sentence,  all
persons owning any unexercised  portions of Options then outstanding  shall have
the right, at such time prior to the  consummation  of the  transaction  causing
such  termination as the Company shall  designate,  to exercise the  unexercised
portions of their Options,  including the portions  thereof which would, but for
this Section 8.3 not yet be exercisable.

                                   ARTICLE IX
                       DURATION, AMENDMENT AND TERMINATION

         Section 9.1. The Board of Directors may at any time terminate this 1998
Plan or make such  amendments  hereto as it shall deem advisable and in the best
interests of the Company,  without action on the part of the stockholders of the
Company unless such approval is required  pursuant to Section 422 of the Code or
the  regulations  thereunder or other federal or state law;  PROVIDED,  HOWEVER,
that  no such  termination  or  amendment  shall,  without  the  consent  of the
individual to whom any Option shall  theretofore  have been granted,  materially
adversely  affect or impair the  rights of such  individual  under such  Option.
Pursuant  to  Section  422(b) of the Code,  no  Incentive  Option may be granted
pursuant  to this  1998 Plan  after  ten  years  from the date this 1998 Plan is
adopted  or the date this  1998  Plan is  approved  by the  stockholders  of the
Company, whichever is earlier.

                                    ARTICLE X
                                  RESTRICTIONS

         Section 10.1. Any Options and shares of Common Stock issued pursuant to
this 1998 Plan shall be subject to such restrictions on transfer and limitations
as shall,  in the opinion of the  Administrator,  be  necessary  or advisable to
assure  compliance  with the laws,  rules and  regulations  of the United States
government or any state or jurisdiction thereof. In addition,  the Administrator
may in any Stock Option Certificate and Agreement impose such other restrictions
upon  the  disposition  or  exercise  of an  Option  or upon  the  sale or other
disposition of the shares of Common Stock  deliverable  upon exercise thereof as
the Administrator may, in its sole discretion,  determine. By accepting an award
pursuant  to this 1998  Plan,  each  Optionee  shall  thereby  agree to any such
restrictions.

         Section 10.2. Any certificate issued to evidence shares of Common Stock
issued  pursuant  to an Option  shall bear such  legends and  statements  as the
Committee, the Board of Directors or counsel to the Company shall deem advisable
to assure  compliance with the laws,  rules and regulations of the United States
government or any state or jurisdiction  thereof. No shares of Common Stock will
be delivered  pursuant to exercise of the Options  granted  under this 1998 Plan
until the Company has obtained such consents or approvals  from such  regulatory
bodies of the United States  government or any state or jurisdiction  thereof as
the Committee,  the Board of Directors or counsel to the Company deems necessary
or advisable.

                                   ARTICLE XI
                              FINANCIAL ASSISTANCE

         Section 11.1. The Company is vested with authority under this 1998 Plan
to assist any  employee to whom an Option is granted  hereunder  (including  any
officer or  director of the  Company or any of its  subsidiaries  who is also an
employee)  in the  payment of the  purchase  price  payable on  exercise of such
Option,  by lending the amount of such  purchase  price to such employee on such
terms and at such rates of interest  and upon such  security (or  unsecured)  as
shall have been authorized by or under authority of the Board of Directors.  Any
such assistance

                                       vii

shall comply with the  requirements  of Regulation G promulgated by the Board of
the  Federal  Reserve  System,  as  amended  from  time to time,  and any  other
applicable law, rule or regulation.

                                   ARTICLE XII
                              APPLICATION OF FUNDS

         Section  12.1.  The proceeds  received by the Company from the issuance
and sale of Common Stock upon exercise of Options granted  pursuant to this 1998
Plan are to be  added  to the  general  funds  of the  Company  and used for its
corporate purposes as determined by the Board of Directors.

                                  ARTICLE XIII
                              EFFECTIVENESS OF PLAN

         Section 13.1.  This 1998 Plan shall become  effective  upon adoption by
the Board of Directors,  and Options may be issued hereunder from and after that
date  subject to the  provisions  of Section  3.3 above.  This 1998 Plan must be
approved  by the  Company's  stockholders  in  accordance  with  the  applicable
provisions  (relating  to the  issuance of stock or  options)  of the  Company's
governing documents and state law or, if no such approval is prescribed therein,
by the affirmative vote of the holders of a majority of the votes cast at a duly
held stockholders  meeting at which a quorum  representing a majority of all the
Company's outstanding voting stock is present and voting (in person or by proxy)
or, without regard to any required time period for approval, by any other method
permitted  by Section 422 of the Code and the  regulations  thereunder.  If such
stockholder  approval is not  obtained  within one year of the  adoption of this
1998 Plan by the Board of  Directors  or within such other time period  required
under  Section 422 of the Code and the  regulations  thereunder,  this 1998 Plan
shall remain in force,  provided  however,  that all Options issued and issuable
hereunder shall automatically be deemed to be Non-Qualified Options.

         IN WITNESS  WHEREOF,  pursuant to the approval of this 1998 Plan by the
Board of Directors,  this 1998 Plan is executed and adopted as of the 7th day of
August, 1998.
