EXHIBIT 4(a)

                       1997 EMPLOYEE STOCK PURCHASE PLAN

     PURPOSE. The Infodata Systems Inc. 1997 Employee Stock Purchase Plan (the
"Plan") is established to provide eligible employees of Infodata Systems Inc.,
a Virginia  corporation,  and its wholly-owned  subsidiaries  (the "Company"),
with an  opportunity  to acquire a proprietary  interest in the Company by the
purchase  of shares of common  stock,  par value $.03 per share  (the  "Common
Stock") of the Company.

     The Company  intends that the Plan shall  qualify as an  "employee  stock
purchase  plan" under  section 423 of the Internal  Revenue  Code of 1986,  as
amended (the "Code"),  including any amendments or  replacements  of such Code
section, and the Plan shall be so construed. Any term not expressly defined in
the Plan but  defined  for  purposes of section 423 of the Code shall have the
same definition herein.

     An employee participating in the Plan (a "Participant") may withdraw such
Participant's   accumulated   payroll   deductions   (if  any)  and  terminate
participation  in the Plan or any Offering (as defined  below)  therein at any
time  during  an  Offering  Period  (as  defined  below).  Accordingly,   each
Participant is, in effect, granted an option pursuant to the Plan (a "Purchase
Right") which may or may not be exercised at the end of an Offering Period.

     ADMINISTRATION.  The Plan shall be administered by the Board of Directors
of  the  Company  (the  "Board")  and/or  by a  duly  appointed  committee  of
non-employee  members of the Board having such powers as shall be specified by
the  Board.  Any  subsequent  references  to the  Board  shall  also  mean the
committee if a committee has been appointed.  All questions of  interpretation
of the Plan or of any  Purchase  Right  shall be  determined  by the Board and
shall be final and  binding  upon all  persons  having an interest in the Plan
and/or any Purchase  Right.  Subject to the  provisions of the Plan, the Board
shall  determine all of the relevant terms and  conditions of Purchase  Rights
granted pursuant to the Plan; provided, however, that all Participants granted
Purchase Rights pursuant to the Plan shall have the same rights and privileges
within the meaning of section  423(b)(5) of the Code. All expenses incurred in
connection with the administration of the Plan shall be paid by the Company.

     SHARE RESERVE. The maximum number of shares which may be issued under the
Plan shall be 200,000 shares of the Company's  authorized but unissued  Common
Stock or Common  Stock which is treasury  stock (the  "Shares").  In the event
that any Purchase  Right for any reason  expires or is canceled or terminated,
the Shares  allocable to the  unexercised  portion of such Purchase  Right may
again be subjected to a Purchase Right.

     ELIGIBILITY.  Any employee of the Company is eligible to  participate  in
the Plan  except  employees  who own or hold  options to purchase or who, as a
result of  participation  in the Plan,  would own or hold options to purchase,
stock  of the  Company  possessing  five  percent  (5%) or  more of the  total
combined  voting power or value of all classes of stock of the Company  within
the meaning of section 423(b)(3) of the Code.  Notwithstanding anything herein
to the contrary,  any  individual  performing  services for the Company solely
through  a  leasing  agency  or  employment  agency  shall  not be  deemed  an
"employee" of the Company.


                                      A-1



     OFFERING DATES.

          (a) OFFERING PERIODS.  Except as otherwise  provided below, the Plan
shall be implemented by offerings  (individually,  an "Offering") of three (3)
months duration (an "Offering Period"); commencing on January 1, April 1, July
1 and October 1 of each year  (beginning  with July 1, 1997) and ending on the
first March 31, June 30, September 30 and December 31, respectively, occurring
thereafter. Notwithstanding the foregoing, the Board may establish a different
term for one or more Offerings and/or different commencing and/or ending dates
for such  Offerings.  An employee who becomes  eligible to  participate in the
Plan  after  an  Offering  Period  has  commenced  shall  not be  eligible  to
participate in such Offering but may  participate  in any subsequent  Offering
provided such employee is still  eligible to participate in the Plan as of the
commencement  of any such  subsequent  Offering.  Eligible  employees  may not
participate  in more than one Offering at a time. The first day of an Offering
Period shall be the "Offering  Date" for such Offering Period and the last day
of an Offering Period shall be the "Purchase  Date" for such Offering  Period.
In the event the first day of an Offering  Period is not a business  day,  the
Offering  Date shall be the first  subsequent  business  day. In the event the
last day of an Offering  Period is not a business day, the Purchase Date shall
be the first preceding business day.

          (b) GOVERNMENTAL APPROVAL; STOCKHOLDER APPROVAL. Notwithstanding any
other  provision  of the Plan to the  contrary,  any  Purchase  Right  granted
pursuant  to the  Plan  shall  be  subject  to  (i)  obtaining  all  necessary
governmental  approvals and/or  qualifications  of the sale and/or issuance of
the Purchase Rights and/or the Shares, and (ii) obtaining stockholder approval
of the Plan.

     PARTICIPATION IN THE PLAN.

          (a) INITIAL  PARTICIPATION.  An  eligible  employee  shall  become a
Participant  on the first  Offering  Date  after  satisfying  the  eligibility
requirements and delivering to the Company's payroll office not later than the
close of business for such payroll office on the last business day before such
Offering Date (the "Subscription  Date") a subscription  agreement  indicating
the employee's  election to participate  in the Plan and  authorizing  payroll
deductions. An eligible employee who does not deliver a subscription agreement
to the Company's  payroll office on or before the Subscription  Date shall not
participate  in the  Plan  for  that  Offering  Period  or for any  subsequent
Offering  Period  unless  such  employee  subsequently  enrolls in the Plan by
filing a subscription  agreement with the Company by the Subscription Date for
such subsequent  Offering Period.  The Company may, from time to time,  change
the  Subscription  Date  as  deemed  advisable  by the  Company  in  its  sole
discretion for proper administration of the Plan.

          (b)  CONTINUED  PARTICIPATION.  A  Participant  shall  automatically
participate in the Offering Period  commencing  immediately after the Purchase
Date of each Offering Period in which the Participant  participates until such
time as such Participant (i) ceases to be eligible as provided in paragraph 4,
(ii) withdraws from the Plan pursuant to paragraph  11(b) or (iii)  terminates
employment  as provided in paragraph 12. If a  Participant  automatically  may
participate in a subsequent  Offering  Period pursuant to this paragraph 6(b),
then the  Participant  is not  required  to file any  additional  subscription
agreement  for  such   subsequent   Offering   Period  in  order  to  continue
participation  in the Plan.  However,  a Participant  may file a  subscription
agreement  with respect to a  subsequent  Offering  Period if the  Participant
desires  to  change  any  of  the  Participant's  elections  contained  in the
Participant's then effective subscription agreement.


                                      A-2



     RIGHT TO PURCHASE SHARES.  Subject to the terms and limitations set forth
below,  during an Offering  Period each  Participant  in such Offering  Period
shall have a Purchase Right consisting of the right to purchase that number of
whole Shares determined in accordance with paragraphs 8 and 9 hereof.

     8. PURCHASE PRICE.  The purchase price at which Shares may be acquired in
a given  Offering  Period  pursuant to the exercise of all or any portion of a
Purchase Right granted under the Plan (the "Offering Exercise Price") shall be
set by the Board;  provided,  however,  that the Offering Exercise Price shall
not be less  than  eighty-five  percent  (85%) of the  lesser  of (a) the fair
market value of the Shares on the Offering Date of the Offering Period, or (b)
the fair market value of the Shares on the Purchase  Date of the same Offering
Period. Unless otherwise provided by the Board prior to the commencement of an
Offering Period, the Offering Exercise Price for that Offering Period shall be
eighty-five  percent  (85%) of the lesser of (a) the fair market  value of the
Shares on the  Offering  Date of such  Offering  Period or (b) the fair market
value of the Shares on the Purchase  Date of such  Offering  Period.  The fair
market value of the Shares on the applicable  dates shall be the closing price
quoted on the National  Association of Securities Dealers Automated  Quotation
System (or the average of the  closing bid and asked  prices if the Shares are
so quoted instead and the quoted closing price is not readily  available),  or
as reported on such other  stock  exchange or market  system if the Shares are
traded on such other exchange or system instead, or as determined by the Board
if the Shares are not so reported.

         PAYMENT OF PURCHASE PRICE.  Shares which are acquired pursuant to the
exercise  of all or any  portion of a  Purchase  Right may be paid for only by
means of payroll  deductions from the Participant's  Compensation  accumulated
during  the  Offering  Period.  For  purposes  of the  Plan,  a  Participant's
"Compensation"  with  respect to an Offering (a) shall  include all  salaries,
before  deduction for any  contributions to any plan maintained by the Company
and described in Section  401(k) or Section 125 of the Code, and (b) shall not
include  commissions,  advances  paid against  future  commissions,  overtime,
bonuses,  annual awards, other incentive payments,  shift premiums,  long-term
disability,  worker's  compensation  or any other  payments  not  specifically
referenced in (a). Except as set forth below, the amount of Compensation to be
withheld  from a  Participant's  Compensation  during each pay period shall be
determined by the Participant's subscription agreement.

          (a) ELECTION TO DECREASE  WITHHOLDING.  During an Offering Period, a
Participant  may  elect  to  decrease  the  amount  withheld  from  his or her
Compensation by filing an amended  subscription  agreement with the Company on
or before the "Change Notice Date." The "Change  Notice Date" shall  initially
be the  seventh  (7th) day prior to the end of the first pay  period for which
such election is to be effective;  however, the Company may change such Change
Notice Date from time to time.  A  Participant  may not elect to increase  the
amount withheld from the Participant's Compensation during an Offering Period.

          (b)  LIMITATIONS  ON  PAYROLL  WITHHOLDING.  The  amount of  payroll
withholding with respect to the Plan for any Participant during any pay period
shall be in one percent (1%) increments not to exceed fifteen percent (15%) of
the  Participant's  Compensation  for such  pay  period.  Notwithstanding  the
foregoing, the Board may change the limits on payroll withholding effective as
of a future Offering Date, as determined by the Board.  Amounts withheld shall
be reduced by any amounts  contributed by the  Participant  and applied to the
purchase of Company stock  pursuant to any other  employee stock purchase plan
qualifying under section 423 of the Code.

          (c) PAYROLL  WITHHOLDING.  Payroll  deductions shall commence on the
first payday  following the Offering Date and shall continue to the end of


                                      A-3



the Offering  Period  unless  sooner  altered or terminated as provided in the
Plan.

 
          (d) PARTICIPANT  ACCOUNTS.  Individual  accounts shall be maintained
for each Participant. All payroll deductions from a Participant's Compensation
shall be credited  to such  account  and shall be  deposited  with the general
funds of the Company.  All payroll deductions  received or held by the Company
may be used by the Company for any corporate purpose.

          (e) NO INTEREST  PAID.  Interest  shall not be paid on sums withheld
from a Participant's Compensation.

          (f) EXERCISE OF PURCHASE RIGHT. Subject to the limitations contained
in paragraph 10 of the Plan, on the Purchase  Date of an Offering  Period each
Participant who has not withdrawn from the Offering or whose  participation in
the  Offering  has not  terminated  on or  before  such  Purchase  Date  shall
automatically  acquire pursuant to the exercise of the Participant's  Purchase
Right the number of whole  Shares  arrived at by dividing  the total amount of
the Participant's  accumulated  payroll  deductions for the Purchase Period by
the Offering  Exercise  Price. No Shares shall be purchased on a Purchase Date
on behalf of a Participant whose participation in the Offering or the Plan has
terminated on or before such Purchase Date.

          (g)  RETURN  OF CASH  BALANCE.  Any cash  balance  remaining  in the
Participant's  account  shall  be  refunded  to the  Participant  as  soon  as
practicable after the Purchase Date. In the event the cash to be returned to a
Participant  pursuant  to the  preceding  sentence  is an amount less than the
amount  necessary  to  purchase  a whole  Share,  the  Company  may  establish
procedures  whereby such cash is maintained in the  Participant's  account and
applied toward the purchase of Shares in the subsequent Offering Period.

          (h) TAX WITHHOLDING. At the time the Purchase Right is exercised, in
whole or in part,  or at the time some or all of the Shares are  disposed  of,
the  Participant  shall make adequate  provision for the foreign,  federal and
state tax  withholding  obligations  of the Company,  if any, which arise upon
exercise  of  the   Purchase   Right  and/or  upon   disposition   of  Shares,
respectively.  The  Company  may,  but shall not be  obligated  to  (except as
required  by  federal  or  state  law),   withhold   from  the   Participant's
Compensation the amount necessary to meet such withholding obligations.

          (i) COMPANY  ESTABLISHED  PROCEDURES.  The Company may, from time to
time, establish (i) a minimum required withholding amount for participation in
an Offering, (ii) limitations on the frequency and/or number of changes in the
amount  withheld  during an Offering,  (iii) an exchange  ratio  applicable to
amounts  withheld  in  a  currency  other  than  U.S.  dollars,  (iv)  payroll
withholding  in excess of or less than the amount  designated by a Participant
in order to adjust for  delays or  mistakes  in the  Company's  processing  of
subscription  agreements,  and/or (v) such other  limitations or procedures as
deemed  advisable by the Company in the Company's  sole  discretion  which are
consistent  with the Plan and in accordance  with the  requirements of section
423 of the Code.

          (j)  EXPIRATION OF PURCHASE  RIGHT.  Any portion of a  Participant's
Purchase Right remaining  unexercised  after the end of the Offering Period to
which such Purchase  Right relates  shall expire  immediately  upon the end of
such Offering Period.

     LIMITATIONS ON PURCHASE OF SHARES: RIGHTS AS A STOCKHOLDER.

          (a)  FAIR  MARKET  VALUE  LIMITATION.   Notwithstanding   any  other


                                      A-4



provision of the Plan,  no  Participant  shall be entitled to purchase  Shares
under the Plan (or any other employee stock purchase plan which is intended to
meet the  requirements of section 423 of the Code sponsored by the Company) at
a rate which exceeds $25,000 in fair market value,  which fair market value is
determined  for  Shares  purchased  during a given  Offering  Period as of the
Offering Date for such Offering  Period (or such other limit as may be imposed
by the Code), for each calendar year in which Participant  participates in the
Plan (or any other employee stock purchase plan described in this sentence).

          (b) PRO RATA  ALLOCATION.  In the event the  number of Shares  which
might be  purchased  by all  Participants  in the Plan  exceeds  the number of
Shares  available in the Plan, the Company shall make a pro rata allocation of
the remaining Shares in as uniform a manner as shall be practicable and as the
Company shall determine to be equitable.

          (c) RIGHTS AS A STOCKHOLDER AND EMPLOYEE.  A Participant  shall have
no rights as a stockholder by virtue of the Participant's participation in the
Plan until the date of the issuance of a stock  certificate(s)  for the Shares
being purchased pursuant to the exercise of the Participant's  Purchase Right.
No  adjustment  shall be made for cash  dividends  or  distributions  or other
rights  for  which  the   record   date  is  prior  to  the  date  such  stock
certificate(s) are issued.  Nothing herein shall confer upon a Participant any
right to continue in the employ of the  Company or  interfere  in any way with
any right of the Company to  terminate  the  Participant's  employment  at any
time.

     WITHDRAWAL.

          (a) WITHDRAWAL FROM AN OFFERING.  A Participant may withdraw from an
Offering by signing and delivering to the Company's  payroll office, a written
notice of withdrawal on a form provided by the Company for such purpose.  Such
withdrawal may be elected at any time prior to the end of an Offering  Period.
Unless otherwise indicated,  withdrawal from an Offering shall not result in a
withdrawal  from  the  Plan or any  subsequent  Offerings.  A  Participant  is
prohibited  from again  participating  in the same  Offering at any time after
withdrawing from such Offering.  The Company may impose,  from time to time, a
requirement  that the  notice  of  withdrawal  be on file  with the  Company's
payroll  office for a  reasonable  period  prior to the  effectiveness  of the
Participant's withdrawal from an Offering.

          (b)  WITHDRAWAL  FROM THE PLAN. A Participant  may withdraw from the
Plan by  signing a written  notice of  withdrawal  on a form  provided  by the
Company for such purpose and delivering  such notice to the Company's  payroll
office.  Withdrawals  made after a Purchase Date for an Offering  Period shall
not affect Shares  acquired by the  Participant  on such Purchase Date. In the
event a  Participant  voluntarily  elects  to  withdraw  from  the  Plan,  the
Participant may not resume  participation in the Plan during the same Offering
Period, but may participate in any subsequent Offering under the Plan by again
satisfying the  requirements  of paragraphs 4 and 6(a) above.  The Company may
impose,  from time to time, a requirement  that the notice of withdrawal be on
file with the Company s payroll  office for a  reasonable  period prior to the
effectiveness of the Participant's withdrawal from the Plan.

          (c) RETURN OF PAYROLL  DEDUCTIONS.  Upon withdrawal from an Offering
or the Plan, the Participant's  accumulated  payroll deductions which have not
been  applied  toward the  purchase  of Shares  shall be  returned  as soon as
practicable after the withdrawal,  without the payment of any interest, to the
Participant,  and the Participant's  interest in the Offering and/or the Plan,
as applicable, shall terminate. Such accumulated payroll deductions may not be
applied  to any other  Offering  under the Plan  following  the  Participant's
withdrawal.


                                      A-5



          (d) PARTICIPATION FOLLOWING WITHDRAWAL; RESALES OF SHARES BY SECTION
16  PERSONS.  A Section  16 Person  (as  defined  below)  may not sell  Shares
acquired by such  Section 16 Person under the Plan until such Shares have been
held by such  Section 16 Person for at least six (6) months.  In  addition,  a
Section 16 Person who is deemed to "cease  participation"  in the Plan  within
the meaning of either Rule 16b-3 promulgated under the Securities Exchange Act
of 1934, as amended (the "Exchange Act"), and amended from time to time or any
successor  rule or regulation  ("Rule 16b- 3"), as a consequence of his or her
withdrawal from an Offering pursuant to paragraph 11(a) above, withdrawal from
the Plan  pursuant to  paragraph  11(b) above,  or  reduction  in  withholding
pursuant to paragraph 9(a) above,  shall not again participate in the Plan for
at least six (6)  months  after the date of such  withdrawal.  A  "Section  16
Person"  shall  include an employee  who is also an officer or director of the
Company subject to Section 16 of the Exchange Act.

          (e) WAIVER OF WITHDRAWAL  RIGHT. The Company may, from time to time,
establish  a  procedure   pursuant  to  which  a  Participant  may  elect  (an
"Irrevocable  Election"),  prior to the commencement of an Offering Period, to
have all payroll  deductions  accumulated in his or her Plan account as of one
or more  subsequent  Purchase Dates applied to purchase shares under the Plan,
and (i) to waive his or her right to withdraw  from the  Offering or the Plan,
and (ii) to waive his or her right to  increase,  decrease,  or cease  payroll
deductions from his or her Compensation for such Offering during the time such
election  is in  effect.  Such  election  shall be made in  writing  on a form
provided by the Company for such  purpose and must be delivered to the Company
not later than the close of  business  on a date prior to the first day of the
Offering  Period  for  which  such  election  is to  first  be  effective,  as
determined by the Company.  (In order to comply with Rule 16b-3,  a Section 16
Person  (as  defined  in  paragraph  11(d)  above)  who does not make  such an
Irrevocable Election may be required to hold any Shares acquired on a Purchase
Date for at least six (6) months following such Purchase Date.)

     TERMINATION OF EMPLOYMENT. Termination of a Participant's employment with
the Company for any reason, including retirement,  disability or death, or the
failure of a Participant to remain an employee  eligible to participate in the
Plan, shall terminate the Participant's participation in the Plan immediately.
In such event, the payroll  deductions  credited to the Participant's  account
since the last Purchase Date shall, as soon as practicable, be returned to the
Participant or, in the case of the  Participant's  death, to the Participant's
legal representative, and all of the Participant's rights under the Plan shall
terminate.  Interest  shall  not be  paid on sums  returned  to a  Participant
pursuant to this paragraph 12. A Participant  whose  participation has been so
terminated  may again  become  eligible  to  participate  in the Plan by again
satisfying the requirements of paragraphs 4 and 6(a) above.

     TRANSFER OF  CONTROL.  A  "Transfer  of Control"  shall be deemed to have
occurred in the event any of the following occurs with respect to the Company.

          (a) any acquisition of the Company's stock or any  reorganization as
defined in section  368(a)(1)  of the Code to which the  Company is a party as
defined  in  section  368(b) of the Code and in which the  Company  is not the
surviving  corporation or is not immediately after the reorganization  engaged
in the active conduct of a trade or business or in which the  stockholders  of
the Company will own less than fifty percent (50%) of the voting securities of
the surviving corporation; or

          (b) any sale or conveyance of substantially all of the net assets of
the Company,  unless immediately after such sale the Company is engaged in the
active conduct of a trade or business.


                                      A-6



     In the  event  of a  Transfer  of  Control,  the  surviving,  continuing,
successor,  or  purchasing  corporation,  as the case  may be (the  "Acquiring
Corporation"),  shall either assume the Company's rights and obligations under
the Plan or substitute  rights to purchase the Acquiring  Corporation's  stock
for outstanding Purchase Rights,  unless the Company's Board otherwise agrees.
In the event that, with the Board's consent, the Acquiring  Corporation elects
not to assume or substitute for such outstanding Purchase Rights in connection
with a merger in which  the  Company  is not the  surviving  corporation  or a
reverse  triangular  merger in which the Company is the surviving  corporation
where the  stockholders  of the  Company  before  such  merger do not  retain,
directly or indirectly,  at least a majority of the beneficial interest in the
voting stock of the Company after such merger, the Board may, but shall not be
obligated to, provide that any outstanding  Purchase Rights shall be exercised
as of the date of the  Transfer of Control,  as the Board so  determines.  The
exercise of any Purchase Right that was  permissible  solely by reason of this
paragraph 13 shall be  conditioned  upon the  consummation  of the Transfer of
Control.  Any Purchase  Rights which are neither assumed or substituted for by
the  Acquiring  Corporation  nor  exercised  as of the date of the Transfer of
Control shall terminate effective as of the date of the Transfer of Control.

     CAPITAL  CHANGES.  In the event of  changes  in the  common  stock of the
Company  due  to  a  stock  split,   reverse  stock  split,   stock  dividend,
recapitalization,   combination,  reclassification,  or  like  change  in  the
Company's  capitalization,  or in the event of any merger  (including a merger
effected for the purpose of changing the  Company's  domicile),  sale or other
reorganization,  appropriate  adjustments  shall be made by the Company in the
securities  subject to  purchase  under a  Purchase  Right,  the Plan's  share
reserve, the number of shares subject to a Purchase Right, and in the purchase
price per share.

     NON-TRANSFERABILITY.  A  Purchase  Right  may not be  transferred  in any
manner and shall be exercisable during the lifetime of the Participant only by
the  Participant.  The Company,  in its absolute  discretion,  may impose such
restrictions  on  the  transferability  of the  Shares  purchasable  upon  the
exercise of a Purchase Right as it deems  appropriate and any such restriction
shall  be set  forth  in the  respective  subscription  agreement  and  may be
referred to on the certificates evidencing such Shares.

     REPORTS.  Each  Participant  who  exercised  all  or  part  of his or her
Purchase Right for an Offering  Period shall  receive,  as soon as practicable
after  the  Purchase  Date  of  such  Offering   Period,   a  report  of  such
Participant's account setting forth the total payroll deductions  accumulated,
the number of Shares purchased, the fair market value of such Shares, the date
of purchase and the  remaining  cash balance to be refunded or retained in the
Participant's account pursuant to paragraph 9(g) above, if any.

     PLAN TERM.  This Plan shall  continue  until  terminated  by the Board or
until all of the Shares reserved for issuance under the Plan have been issued,
whichever shall first occur.

     RESTRICTION ON ISSUANCE OF SHARES.  The issuance of shares under the Plan
shall be subject to compliance  with all applicable  requirements  of federal,
state or foreign law with respect to such securities. A Purchase Right may not
be exercised if the issuance of shares upon such exercise  would  constitute a
violation of any applicable federal, state or foreign securities laws or other
law or regulations. In addition, no Purchase Right may be exercised unless (i)
a registration  statement under the Securities Act of 1933, as amended,  shall
at the time of exercise of the Purchase Right be in effect with respect to the
shares issuable upon exercise of the Purchase Right,


                                      A-7



or (ii) in the opinion of legal  counsel to the Company,  the shares  issuable
upon exercise of the Purchase Right may be issued in accordance with the terms
of an applicable exemption from the registration  requirements of said Act. As
a condition to the exercise of a Purchase  Right,  the Company may require the
Participant   to  satisfy  any   qualifications   that  may  be  necessary  or
appropriate, to evidence compliance with any applicable law or regulation, and
to  make  any  representation  or  warranty  with  respect  thereto  as may be
requested by the Company.

     LEGENDS.  The Company may at any time place legends or other  identifying
symbols  referencing any applicable  federal,  state and/or foreign securities
restrictions or any provision  convenient in the administration of the Plan on
some or all of the certificates  representing shares of stock issued under the
Plan. The Participant  shall, at the request of the Company,  promptly present
to the Company any and all certificates  representing shares acquired pursuant
to a Purchase Right in the possession of the Participant in order to carry out
the provisions of this paragraph.

     NOTIFICATION  OF SALE OF SHARES.  The Company may require the Participant
to give the Company  prompt notice of any  disposition  of Shares  acquired by
exercise of a Purchase  Right within two years from the date of granting  such
Purchase  Right or one year from the date of exercise of such Purchase  Right.
The Company may direct that the  certificates  evidencing  Shares  acquired by
exercise of a Purchase  Right refer to such  requirement to give prompt notice
of disposition.

     AMENDMENT OR  TERMINATION OF THE PLAN. The Board may at any time amend or
terminate the Plan,  except that such  termination  shall not affect  Purchase
Rights  previously  granted  under the Plan,  nor may any  amendment  make any
change in a Purchase  Right  previous  ly granted  under the Plan which  would
adversely  affect the right of any Participant  (except as may be necessary to
qualify the Plan as an employee stock purchase plan pursuant to section 423 of
the Code or to  obtain  qualification  or  registration  of the  Shares  under
