EXHIBIT 4(a)

                             INFODATA SYSTEMS INC.

                             1995 STOCK OPTION PLAN


1. Purpose

     Infodata Systems Inc. (the  "Company"),  by means of this 1995 Stock Option
Plan (the  "Plan"),  desires to afford  certain of its  directors,  officers and
certain  selected  employees,  consultants and the officers and certain selected
employees  of any  subsidiary  thereof  now  existing  or  hereafter  formed  or
acquired,  an opportunity to acquire a proprietary  interest in the Company, and
thus to create in such  persons an increased  interest in and a greater  concern
for the welfare of the Company and any subsidiary.  The Plan is the successor to
the Company's  Incentive Stock Option Plan and  Non-Qualified  Stock Option Plan
that were approved by the Company's shareholders in 1991 and 1992,  respectively
(the "Prior Plans").  As used in the Plan, the term "subsidiary"  shall mean any
entity  in  which  the  Company,  directly  or  indirectly,  owns a  controlling
interest.

     The stock options described in Sections 6 and 7 hereof (the "Options"), and
the  shares of common  stock,  par value  $.03 per share,  of the  Company  (the
"Common Stock")  acquired  pursuant to the exercise of such Options are a matter
of separate  inducement and are not in lieu of any salary or other  compensation
for services.

     The  Options  granted  under  Section 6 hereof  are  intended  to be either
incentive stock options ("Incentive  Options") within the meaning of Section 422
of the Internal  Revenue Code of 1986, as amended (the "Code"),  or options that
do not meet the requirements for Incentive  Options  ("Non-Qualified  Options"),
but the Company  makes no warranty as to the  qualification  of any Option as an
Incentive Option.

2. Administration

     The Plan  shall  be  administered  by the  Compensation  Committee,  or any
successor  thereto,  of the Board of  Directors  of the Company or by such other
committee as determined  by the Board (the  "Committee").  The  Committee  shall
consist of not less than two members of the Board of  Directors  of the Company,
each of whom shall qualify as a  "disinterested  person" to administer  the Plan
within the meaning of Rule 16b-3, as amended,  or other  applicable  rules under
Section 16(b) of the Securities  Exchange Act of 1934, as amended (the "Exchange
Act").  The Committee  shall  administer  the Plan so as to conform at all times
with the provisions of Rule 16b-3 promulgated under the Exchange Act. A majority
of the Committee shall constitute a quorum, and subject to the provisions

                                      D-1



of  Section 5 hereof,  the acts of a  majority  of the  members  present  at any
meeting at which a quorum is present, or acts approved unanimously in writing by
the Committee, shall be the acts of the Committee.

     The Committee may delegate to one or more of its members, or to one or more
agents, such administrative  duties as it may deem advisable,  and the Committee
or any person to whom it has  delegated  duties as  aforesaid  may employ one or
more persons to render advice with respect to any  responsibility  the Committee
or such  person may have under the Plan.  The  Committee  may employ  attorneys,
consultants,  accountants,  or other persons and the Committee,  the Company and
its officers and directors  shall be entitled to rely upon the advice,  opinions
or valuations of any such persons. All actions taken and all interpretations and
determinations  made by the  Committee  in good faith shall be final and binding
upon all persons who have  received  grants under the Plan,  the Company and all
other  interested  persons.  No  member  or  agent  of the  Committee  shall  be
personally liable for any action,  determination or interpretation  made in good
faith with respect to the Plan and all members and agents of the Committee shall
be fully  protected by the Company in respect of any such action,  determination
or interpretation.

3. Shares Available

     Subject  to the  adjustments  provided  in  Section 9 hereof,  the  maximum
aggregate  number of shares of Common Stock which may be  purchased  pursuant to
the exercise of Options  granted under the Plan shall not exceed  433,333.  Such
amount includes the 333,333 shares (giving effect to the  one-for-three  reverse
split of the Common Stock  effected  April 27, 1994)  previously  authorized for
possible  issuance under the Prior Plans.  If, for any reason,  any shares as to
which  Options  have been  granted  cease to be subject to purchase  thereunder,
including without limitation the expiration of such Options,  the termination of
such Options prior to exercise or the  forfeiture  of such Options,  such shares
thereafter shall be available for grants to such individual or other individuals
under the Plan.  Options  granted  under the Plan may be fulfilled in accordance
with the terms of the Plan with either  authorized and unissued shares of Common
Stock or issued  shares of such Common Stock held in the  Company's  treasury or
both, at the discretion of the Company.

4. Eligibility and Bases of Participation

     Grants  under the Plan (i) may be made,  pursuant  to Section 6 hereof,  to
certain selected employees and officers (but not to any director who is not also
an employee) of the Company or any subsidiary thereof who are regularly employed
on a  salaried  basis and who are so  employed  on the date of such  grant  (the
"Officer  and  Certain  Selected  Employee  Participants");  (ii)  may be  made,
pursuant to Section 6 hereof, to directors of the Company, other

                                      D-2



than Committee  Participants  (as defined below),  who are not employees and who
are  retained  by the  Company in such  capacity  on the date of such grant (the
"Director  Participants");  (iii) may be made,  pursuant to Section 6 hereof, to
consultants or advisors, provided that the services rendered by such consultants
or advisors shall not be in connection with the offer or sale of securities in a
capital-raising  transaction  (the "Consultant  Participants")  (the Officer and
Certain Selected Employee Participants, Director
Participants and Consultant  Participants are hereinafter  collectively referred
to as the "Grant  Participants");  and (iv) may be made,  pursuant  to Section 7
hereof, to individuals who serve on the Committee or have been named to serve on
the Committee in the future (the "Committee Participants").

5. Authority of Committee

     Subject to and not inconsistent with the express provisions of the Plan and
the Code, the Committee shall have plenary  authority,  in its sole  discretion,
to:

     a.   other  than with  respect to  Committee  Participants,  determine  the
          persons to whom Options  shall be granted,  the time when such Options
          shall be granted, the number of shares of Common Stock underlying each
          Option,  the  purchase  price or exercise  price of each  Option,  the
          restrictions  to be  applicable  to  Options  and the other  terms and
          provisions thereof (which need not be identical);

     b.   provide  an  arrangement  through  registered  broker-dealers  whereby
          temporary  financing  may be  made  available  to an  optionee  by the
          broker-dealer  for  the  purpose  of  assisting  the  optionee  in the
          exercise of an Option;

     c.   establish  procedures  for an optionee to pay the exercise price of an
          Option  in whole or in part by  delivering  that  number  of shares of
          Common  Stock owned by such  optionee;  or for the  collection  of any
          taxes required by any government to be withheld or otherwise  deducted
          and paid by the Company or any  subsidiary  in respect of the issuance
          or disposition of Common Stock acquired pursuant to the exercise of an
          Option granted  hereunder,  which  procedures  may include  payment in
          whole or in part  through the delivery of shares of Common Stock owned
          by the  optionee  valued  on the  basis of the Fair  Market  Value (as
          defined in Section 11 hereof) on the date preceding such exercise;

     d.   prescribe, amend, modify and rescind rules and regulations relating to
          the Plan;

     e.   make all determinations specified in or permitted by the

                                      D-3



          Plan or deemed  necessary or desirable for its  administration  or for
          the conduct of the Committee's business; and

     f.   establish any  procedures  determined to be appropriate in discharging
          its responsibilities under the Plan.

6.  Stock Options for Grant Participants

     The Committee  shall have the  authority,  in its sole  discretion to grant
Incentive  Options  or  Non-Qualified  Options  or both  Incentive  Options  and
Non-Qualified  Options to Grant  Participants  (any such Options are hereinafter
collectively  referred  to as  the  "Participant  Options")  during  the  period
beginning on the date on which the Plan is approved by the holders of a majority
of the Company's  outstanding shares of Common Stock and Preferred Stock, voting
as a class (the  "Effective  Date") and ending on the tenth  anniversary  of the
Effective Date (the  "Termination  Date").  Notwithstanding  anything  contained
herein to the  contrary,  Incentive  Options may be granted  only to Officer and
Certain Selected  Employee  Participants.  As a condition to the granting of any
Option,  the Committee shall require that the person receiving such Option agree
not to sell or otherwise  dispose of any Common Stock acquired  pursuant to such
Option  for a period  of six  months  following  the  date of the  grant of such
Option. The terms and conditions of the Participant  Options shall be determined
from time to time by the  Committee;  provided,  however,  that the  Participant
Options granted under the Plan shall be subject to the following:

     a.   Exercise  Price.  The  exercise  price for each share of Common  Stock
          purchasable  under any Participant  Option granted  hereunder shall be
          such amount as the Committee, in its best judgment, shall determine to
          be not less than 100% of the Fair Market  Value (as defined in Section
          11 hereof)  per share on the date the  Participant  Option is granted;
          provided,  however, that in the case of an Incentive Option granted to
          a person  who,  at the time such  Incentive  Option is  granted,  owns
          shares of capital  stock of the Company,  or of any  subsidiary of the
          Company,  having more than 10% of the total  combined  voting power of
          all  classes  of shares of  capital  stock of the  Company  or of such
          subsidiary,  the exercise  price for each share shall be not less than
          110% of the Fair  Market  Value (as  defined in Section 11 hereof) per
          share on the date the Incentive Option is granted.  In determining the
          stock  ownership of a person for purposes of this Section 6, the rules
          of Section  424(d) of the Code shall be applied and the  Committee may
          rely on representations of fact made to it by such person and believed
          by it to be true. The exercise price of the  Participant  Options will
          be subject to adjustment in accordance  with the provisions of Section
          9 hereof.

                                      D-4



     b.   Payment.  The exercise price per share of Common Stock with respect to
          each  Participant  Option shall be payable at the time the Participant
          Option is exercised. Such price shall be payable in cash, which may be
          paid by wire transfer in immediately  available  funds, by check, by a
          commitment  by a  broker-dealer  to pay to the Company that portion of
          any sale  proceeds  receivable  by the  optionee  upon  exercise  of a
          Participant  Option  or by  any  other  instrument  acceptable  to the
          Company or, in the  discretion  of the  Committee,  by delivery to the
          Company of shares of Common Stock.  Shares delivered to the Company in
          payment of the exercise price shall be valued at the Fair Market Value
          (as defined in Section 11 hereof) of the Common  Stock on the business
          day immediately  preceding the date of the exercise of the Participant
          Option.

     c.   Exercisability of Participant  Options.  Subject to this Section 6 and
          Section  8 hereof,  each  Participant  Option  shall  vest and  become
          exercisable  on  the  dates  and  in  the  amounts  set  forth  in the
          particular  stock  option  agreement   between  the  Company  and  the
          optionee;  provided,  however,  that a Participant Option shall expire
          not later than five years from the date such  Option is  granted.  The
          right to purchase shares shall be cumulative so that when the right to
          purchase any shares has  accrued,  such shares or any part thereof may
          be  purchased  at  any  time   thereafter   until  the  expiration  or
          termination of the Participant Option.

     d.   Death.  In the  event of the  death of an  optionee,  all  Participant
          Options held by such  optionee on the date of such death shall vest in
          full and become  immediately  exercisable.  Upon such death, the legal
          representative  of such  optionee,  or such person who  acquired  such
          Participant  Options  by bequest  or  inheritance  or by reason of the
          death of the  optionee,  shall  have the right for one year  after the
          date of death  (but not after the  expiration  or  termination  of the
          Participant Options), to exercise such optionee's  Participant Options
          with respect to all or any part of the shares of Common Stock  subject
          thereto.

     e.   Disability.  If the employment of an optionee is terminated because of
          Disability (as defined in Section 11 hereof),  all Participant Options
          held by such  optionee on the date of such  termination  shall vest in
          full and become immediately exercisable.  Such optionee shall have the
          right for one year after the date of such  termination  (but not after
          the expiration or termination of the Participant Options), to exercise
          such optionee's Participant Options with respect to all or any part of
          the shares of Common Stock subject thereto.

                                      D-5



     f.   Retirement.  In the event the  employment  of an Officer  and  Certain
          Selected   Employee   Participant  is  terminated  by  reason  of  the
          Retirement  (as  defined in Section  11 hereof) of the  optionee,  all
          Participant  Options  held  by  such  optionee  on the  date  of  such
          termination  shall  vest in full and become  immediately  exercisable.
          Such optionee  shall have the right for three months after the date of
          such  termination  (but not after the expiration or termination of the
          Participant Options), to exercise such optionee's  Participant Options
          with respect to all or any part of the shares of Common Stock  subject
          thereto. The Committee, in its discretion,  shall determine whether an
          optionee's  employment  was  terminated  by reason of  Retirement  and
          whether such  optionee is entitled to the  treatment  afforded by this
          subsection f.

     g.   Other  Termination.  If  the  employment  of an  Officer  and  Certain
          Selected Employee  Participant is terminated for any reason other than
          those  specified  in  subsections  d, e, and f of this Section 6, such
          optionee  shall  have the  right  for 30 days  after  the date of such
          termination  (but not  after  the  expiration  or  termination  of the
          Participant Options), to exercise such optionee's  Participant Options
          with  respect to all or any part of the shares of Common  Stock  which
          such optionee was entitled to purchase  immediately  prior to the time
          of such termination.

     h.   Cessation of Directorship.  In the event a Director  Participant shall
          cease to be a director of the Company,  such  optionee  shall have the
          right for 90 days after the date of such  cessation (but not after the
          expiration or termination  of the  Participant  Options),  to exercise
          such optionee's Participant Options with respect to all or any part of
          the shares of Common Stock subject thereto.

     i.   Maximum  Exercise.  To the extent the aggregate  Fair Market Value (as
          defined in Section 11 hereof) of Common Stock  (determined at the time
          of the grant) with respect to which Incentive  Options are exercisable
          for the first time by an optionee  during any calendar  year under all
          plans of the  Company or any  subsidiary,  exceeds  $100,000,  or such
          other  amount as may be  prescribed  under  Section 422 of the Code or
          applicable  regulations  or  rulings  from  time to time,  the  excess
          thereof  shall  be  treated  as  Non-  Qualified  Options  and  not as
          Incentive Options.


7. Stock Option Grants to Committee Participants

     During  the term of the Plan,  on the date that a director  of the  Company
commences  service on the Committee (which in the case of the initial members of
the Committee shall be deemed to be the

                                                      D-6





Effective Date), and on the date of any subsequent annual meeting of the holders
of the Common Stock at which a director is elected and appointed or  reappointed
to serve on the Committee,  such Committee  Participant  automatically  shall be
granted a Non- Qualified Option to purchase 2,000 shares of Common Stock,  which
Non-Qualified  Option, except as otherwise provided in this Section 7 or Section
8 hereof, shall become fully exercisable immediately upon grant as to all of the
shares  covered  thereby.  (A  Non-  Qualified  Option  granted  to a  Committee
Participant  pursuant to this Section 7 is referred to as a "Committee Option".)
As a condition to the granting of any  Committee  Option,  the person  receiving
such Committee Option shall agree not to sell or otherwise dispose of any Common
Stock acquired  pursuant to such Option for a period of six months following the
date of the grant of such  Option.  The terms and  conditions  of the  Committee
Options shall be as follows:

     a.   Option  Price.  The  exercise  price  of each  share of  Common  Stock
          purchasable  under any  Committee  Options shall be such amount as the
          Committee,  in its best  judgment,  shall  determine to be 100% of the
          Fair  Market  Value (as defined in Section 11 hereof) per share at the
          date the Committee Option is granted.

     b.   Payment.  The exercise price per share of Common Stock with respect to
          each Committee  Option and any  withholding tax due in connection with
          such  exercise  may be  paid  by any of the  methods  described  under
          Section 6b hereof.

     c.   Exercisability.  Except as provided in subsection d of this Section 7,
          no Committee Option shall be exercisable  after the earlier of (i) the
          expiration  of five  years  from the date  such  Committee  Option  is
          granted and (ii) 90 days after such Committee  Participant  ceases for
          any reason to be a director of the Company.

     d.   Death.  In the event of the death of any  Committee  Participant,  the
          estate of the Committee  Participant shall have the right for one year
          after the date of death (but not after the  expiration or  termination
          of such Committee Options),  to exercise such Committee  Participant's
          Committee  Options  with  respect  to all or any part of the shares of
          Common Stock subject thereto.

     e.   Amendment.  The provisions of this Section 7 shall not be amended more
          than one time in any six-month period,  other than to comport with any
          amendments to the Code, the Employee Retirement Income Security Act of
          1974, as amended, or the rules and regulations thereunder.


                                      D-7



8. Change of Control

     Notwithstanding  any provision herein to the contrary,  upon the occurrence
of an event  constituting a Change of Control (as defined in Section 11 hereof),
all Options granted under the Plan immediately shall become fully exercisable.

9. Adjustment of Shares

     In the event the  outstanding  shares of Common Stock shall be increased or
decreased or changed into or exchanged for a different  number of kind of shares
of stock or other securities of the Company or another  corporation by reason of
any   consolidation,   merger,   combination,    liquidation,    reorganization,
recapitalization,  stock dividend, stock split, split-up,  split-off,  spin-off,
combination  of  shares,  exchange  of shares or other  like  change in  capital
structure of the Company,  the number or kind of shares or interests  subject to
an  Option  and the per  share  price or value  thereof  shall be  appropriately
adjusted by the Committee at the time of such event.  Any  fractional  shares or
interests  resulting from such adjustment  shall be eliminated.  Notwithstanding
the  foregoing,  (i) each such  adjustment  with respect to an Incentive  Option
shall  comply with the rules of Section  424(a) of the Code and (ii) in no event
shall any adjustment be made that would result in an Incentive Option failing to
be treated as an  "incentive  stock  option" for  purposes of Section 422 of the
Code.  In addition,  in such event the Board of  Directors of the Company  shall
appropriately  adjust the number of shares of Common Stock for which Options may
be granted under the Plan.

10.      Miscellaneous Provisions

     a.   Assignment  or Transfer.  No grant of any  "derivative  security"  (as
          defined by Rule  16a-1(c)  under the Exchange Act) made under the Plan
          or any rights or interests therein shall be assignable or transferable
          by an optionee except by will or the laws of descent and  distribution
          or, except as to Incentive  Options,  pursuant to a qualified domestic
          relations  order as defined in the Code.  During  the  lifetime  of an
          optionee,  Options granted  hereunder shall be exercisable only by the
          optionee or the optionee's guardian or legal representative.

     b.   Investment  Representation.  If a  registration  statement  under  the
          Securities  Act of 1933,  as  amended  (the  "Securities  Act"),  with
          respect to the Common Stock issuable upon exercise of an Option is not
          in effect  at the time  such  Option is  exercised,  the  Company  may
          require,  for the sole purpose of complying with the  Securities  Act,
          that prior to delivering such Common Stock to the exercising  optionee
          such optionee must

                                      D-8



          deliver  to the  Secretary  of the  Company  a written  statement  (i)
          representing  that such Common Stock is being  acquired for investment
          only and not with a view to the resale or distribution  thereof,  (ii)
          acknowledging that such Common Stock may not be sold unless registered
          for sale under the  Securities  Act or pursuant to an  exemption  from
          such registration and (iii) agreeing that the certificates  evidencing
          such Common Stock shall bear a legend to the foregoing effect.

     c.   Costs and Expenses.  The costs and expenses of administering  the Plan
          shall be borne by the  Company  and shall not be charged  against  any
          Option nor to any person receiving an Option.

     d.   Funding of Plan. The Plan shall be unfunded.  The Company shall not be
          required to make any segregation of assets to assure the  satisfaction
          of any Option under the Plan.

     e.   Other Incentive  Plans. The adoption of the Plan does not preclude the
          adoption  by  appropriate  means  of  any  other  incentive  plan  for
          officers, directors or employees.

     f.   Effect on Employment.  Nothing  contained in the Plan or any agreement
          related hereto or referred to herein shall affect,  or be construed as
          affecting, the terms of employment of any Grant Participants except to
          the extent specifically provided herein or therein.  Nothing contained
          in the Plan or any  agreement  related  hereto or  referred  to herein
          shall  impose,  or be construed as imposing,  an obligation on (i) the
          Company or any  subsidiary  to continue  the  employment  of any Grant
          Participant  or (ii) any Grant  Participant to remain in the employ of
          the Company or any subsidiary.

     g.   Termination  or Suspension of the Plan.  The Board of Directors may at
          any time  suspend  or  terminate  the Plan.  The Plan,  unless  sooner
          terminated  under  Section 12 of the Plan or by action of the Board of
          Directors, shall terminate at the close of business on the Termination
          Date.  Options may not be granted while the Plan is suspended or after
          it is  terminated.  Rights and  obligations  under any Option  granted
          while  the Plan is in effect  shall  not be  altered  or  impaired  by
          suspension or termination of the Plan,  except with the consent of the
          person to whom the Option was granted.  The power of the  Committee to
          construe and administer any Option granted prior to the termination or
          suspension  of  the  Plan  nevertheless   shall  continue  after  such
          termination or during such suspension.

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

     i.   Partial  Invalidity.  The  invalidity  or  illegality of any provision
          herein  shall  not be  deemed  to  affect  the  validity  of any other
          provision.

11. Definitions

     a.   "Fair Market Value", as it relates to the Common Stock, shall mean the
          average of the high and low sale  prices of such  Common  Stock on the
          date such  determination is required herein, or if there were no sales
          on such date, the average closing bid and asked prices, as reported on
          the national  securities  exchange on which the Company's Common Stock
          is listed or, in the absence of such listing,  on the Nasdaq  National
          Market or Small Cap Market or, if such Common Stock is not at the time
          listed on a  national  securities  exchange  or  traded on the  Nasdaq
          National Market or Small Cap Market, the value of such Common Stock on
          such date as determined in good faith by the Committee.

     b.   "Disability"  shall have the meaning set forth in Section  22(e)(3) of
          the Code.

     c.   "Change of Control" shall be deemed to have occurred if, subsequent to
          the Effective Date of this Plan, any "person" (as such term is defined
          in Section  13(d) of the Exchange Act) becomes the  beneficial  owner,
          directly or  indirectly,  of either (x) a majority of the Common Stock
          or (y)  securities  of the  Company  representing  a  majority  of the
          combined  voting  power  of  the  Company's  then  outstanding  voting
          securities.

     d.   "Retirement"  shall  mean the  date  upon  which a Grant  Participant,
          having  attained an age as may be  determined  by the Committee in its
          sole  discretion,  terminates his  employment  with the Company or any
          subsidiary,  provided that such Grant Participant has been employed by
          the Company or any subsidiary.


12. Amendment of Plan

     The  Board of  Directors  of the  Company  shall  have the  right to amend,
modify, suspend or terminate the Plan at any time, provided

                                      D-10



that no amendment  shall be made without  shareholder  approval  which shall (i)
increase the total number of shares of the Common Stock of the Company which may
be issued  and sold  pursuant  to Options  granted  under the Plan  (except  for
increases  due to  adjustments  in  accordance  with  Section  9  hereof),  (ii)
materially  increase the benefits accruing to participants under the Plan, (iii)
decrease the minimum  exercise price in the case of an Incentive  Option or (iv)
materially  modify the  provisions  of the Plan  relating  to  eligibility  with
respect  to  Options.  In no event may the Plan be amended in any way that would
retroactively impair the Committee's discretion. The Board of Directors shall be
authorized to amend the Plan and the Options  granted  thereunder (A) to qualify
such Options as "incentive  stock options"  within the meaning of Section 422 of
the Code or (B) to comply  with Rule  16b-3 (or any  successor  rule)  under the
Exchange Act. No amendment, modification, suspension or termination of the Plan,
without the consent of the holder  thereof,  shall adversely alter or impair any
Options previously granted under the Plan.

13. Effective Date

     The Plan shall become effective on the Effective Date. Subject to the right
of the Board of Directors to terminate  the Plan at any time pursuant to Section
12 hereof,  the Plan shall  remain in effect  until the  earlier of (i) the date
that Options  covering all shares of Common Stock  issuable  under the Plan have
been granted or (ii) the Termination Date.
