# INFODATA SYSTEMS INC.
1997 EMPLOYEE STOCK PURCHASE PLAN, AS AMENDED

1.       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.

2.       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.

3.       Share
Reserve. The maximum number of shares which may be issued under the           Plan
shall be 400,000 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.

4.       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.

5.       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 last day that the Companys common stock is traded in each of the
          three-month periods ending 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.

6.       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 Human Resources office not later than the close           of business
for such Human Resources 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 Human Resources 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.

7.       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
          ninety percent (90%) 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.

9.       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
tenth (10th) 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 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.

10.       Limitations
on Purchase of Shares: Rights as a Stockholder.

(a)       Fair
Market Value Limitation. Notwithstanding any other 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.

11.       
Withdrawal.

(a)       Withdrawal
From an Offering. A Participant may withdraw from an Offering           by signing
and delivering to the Companys Human Resources 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
          Human Resources 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 Human Resources           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 Human Resources 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.

(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.)

12.       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.

13.       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.

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.

14.       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.

15.       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.

16.       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.

17.       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.

18.       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, 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.

19.       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.

20.       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.

21.       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 previously 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 applicable federal,
          state or foreign securities laws). In addition, an amendment to the Plan must
be           approved by the stockholders of the Company within twelve (12) months of the
          adoption of such amendment if such amendment would authorize the sale of more
          shares than are authorized for issuance under the Plan.
