                      NON-QUALIFIED STOCK OPTION AGREEMENT

                               ONESOFT CORPORATION


         THIS AGREEMENT, is made as of _________________ between OneSoft,
Corporation (the "Company"), a Delaware corporation having its principal place
of business at 1505 Farm Credit Drive, McLean, Virginia 22102, and
_______________ (the "Participant"), having an address at ________________.

         WHEREAS, the Company desires to grant to the Participant an Option to
purchase shares of its common stock, $.001 par value per share (the "Shares"),
under and for the purposes set forth in the Company's 1997 Employee, Director
and Consultant Stock Option Plan (the "Plan"); and

         WHEREAS, the Company and the Participant understand and agree that any
terms used and not defined herein have the same meanings as in the Plan; and

         WHEREAS, the Company and the Participant each intend that the Option
granted herein shall be a Non-Qualified Option.

         NOW THEREFORE, in consideration of the mutual covenants hereinafter set
forth and for other good and valuable consideration, the parties hereto agree as
follows:

1.       GRANT OF OPTION.
         ---------------

         The Company hereby grants to the Participant the right and option to
purchase all or any part of an aggregate of ___________(XXX) Shares, on the
terms and conditions and subject to all the limitations set forth herein and in
the Plan, which is incorporated herein by reference. The Participant
acknowledges receipt of a copy of the Plan.

2.       PURCHASE PRICE.
         --------------

         The purchase price of the Shares covered by the Option shall be
____________($XXX) per Share, subject to adjustment, as provided in the Plan, in
the event of a stock split, reverse stock split or other events affecting the
holders of Shares. Payment shall be made in accordance with Paragraph 7 of the
Plan.

3.       EXERCISE OF OPTION.
         ------------------

         Subject to the terms and conditions set forth in this Agreement and the
Plan, the Option granted hereby shall become exercisable as follows:

XXXX:                      XXX Shares

         The foregoing rights are cumulative and are subject to the other terms
and conditions
<PAGE>

of this Agreement and the Plan.

4.       TERM OF OPTION.
         --------------

         The Option shall terminate ten (10) years from the date of this
Agreement, but shall be subject to earlier termination as provided herein or in
the Plan.

         If the Participant ceases to be an employee, director or consultant of
the Company or of an Affiliate (for any reason other than the death or
Disability of the Participant or termination of the Participant for "cause" (as
defined in the Plan)), the Option may be exercised, if it has not previously
terminated, within three (3) months after the date the Participant ceases to be
an employee, director or consultant of the Company or an Affiliate, or within
the originally prescribed term of the Option, whichever is earlier, but may not
be exercised thereafter. In such event, the Option shall be exercisable only to
the extent that the Option has become exercisable and is in effect at the date
of such cessation of employment, directorship or consultancy.

         Notwithstanding the foregoing, in the event of the Participant's
Disability or death within three (3) months after the termination of employment,
directorship or consultancy, the Participant or the Participant's Survivors may
exercise the Option within one (1) year after the date of the Participant's
termination of employment, directorship or consultancy, but in no event after
the date of expiration of the term of the Option.

         In the event the Participant's employment, directorship or consultancy
is terminated by the Company or an Affiliate for "cause" (as defined in the
Plan), the Participant's right to exercise any unexercised portion of this
Option shall cease as of such termination, and this Option shall thereupon
terminate. Notwithstanding anything herein to the contrary, if subsequent to the
Participant's termination, but prior to the exercise of the Option, the Board of
Directors of the Company determines that, either prior or subsequent to the
Participant's termination, the Participant engaged in conduct which would
constitute "cause," then the Participant shall immediately cease to have any
right to exercise the Option and this Option shall thereupon terminate.

         In the event of the Disability of the Participant, as determined in
accordance with the Plan, the Option shall be exercisable within one (1) year
after the date of such Disability or, if earlier, the term originally prescribed
by the Option. In such event, the Option shall be exercisable:

         (a)      To the extent exercisable but not exercised as of the date of
                  Disability; and

         (b)      In the event rights to exercise the Option accrue
                  periodically, to the extent of a pro rata portion of any
                  additional rights to exercise the Option as would have accrued
                  had the Participant not become Disabled prior to the end of
                  the accrual period

                                      -2-
<PAGE>

                  which next ends following the date of Disability. The
                  pro-ration shall be based upon the number of days during the
                  accrual period prior to the date of Disability.

         In the event of the death of the Participant while an employee,
director or consultant of the Company or of an Affiliate, the Option shall be
exercisable by the Participant's Survivors within one (1) year after the date of
death of the Participant or, if earlier, within the originally prescribed term
of the Option. In such event, the Option shall be exercisable:

         (a)      To the extent exercisable but not exercised as of the date of
                  death; and

         (b)      In the event rights to exercise the Option accrue
                  periodically, to the extent of a pro rata portion of any
                  additional rights to exercise the Option as would have accrued
                  had the Participant not died prior to the end of the accrual
                  period which next ends following the date of death. The
                  pro-ration shall be based upon the number of days during the
                  accrual period prior to the Participant's death.


5.       METHOD OF EXERCISING OPTION.
         ---------------------------

         Subject to the terms and conditions of this Agreement, the Option may
be exercised by written notice to the Company at its principal executive office,
in substantially the form of Exhibit A attached hereto. Such notice shall state
                             ---------
the number of Shares with respect to which the Option is being exercised and
shall be signed by the person exercising the Option. Payment of the purchase
price for such Shares shall be made in accordance with Paragraph 7 of the Plan.
The Company shall deliver a certificate or certificates representing such Shares
as soon as practicable after the notice shall be received, provided, however,
that the Company may delay issuance of such Shares until completion of any
action or obtaining of any consent, which the Company deems necessary under any
applicable law (including, without limitation, state securities or "blue sky"
laws). The certificate or certificates for the Shares as to which the Option
shall have been so exercised shall be registered in the name of the person or
persons so exercising the Option (or, if the Option shall be exercised by the
Participant and if the Participant shall so request in the notice exercising the
Option, shall be registered in the name of the Participant and another person
jointly, with right of survivorship) and shall be delivered as provided above to
or upon the written order of the person or persons exercising the Option. In the
event the Option shall be exercised, pursuant to Section 4 hereof, by any person
or persons other than the Participant, such notice shall be accompanied by
appropriate proof of the right of such person or persons to exercise the Option.
All Shares that shall be purchased upon the exercise of the Option as provided
herein shall be fully paid and non-assessable.

6.       PARTIAL EXERCISE.
         ----------------

         Exercise of this Option to the extent above stated may be made in part
at any time and

                                      -3-
<PAGE>

from time to time within the above limits, except that no fractional share shall
be issued pursuant to this Option.

7.       NON-ASSIGNABILITY.
         -----------------

         The Option shall not be transferable by the Participant otherwise than
by will or by the laws of descent and distribution or pursuant to a qualified
domestic relations order as defined by the Code or Title I of the Employee
Retirement Income Security Act or the rules thereunder. Except as provided in
the previous sentence, the Option shall be exercisable, during the Participant's
lifetime, only by the Participant (or, in the event of legal incapacity or
incompetency, by the Participant's guardian or representative) and shall not be
assigned, pledged or hypothecated in any way (whether by operation of law or
otherwise) and shall not be subject to execution, attachment or similar process.
Any attempted transfer, assignment, pledge, hypothecation or other disposition
of the Option or of any rights granted hereunder contrary to the provisions of
this Section 7, or the levy of any attachment or similar process upon the Option
shall be null and void.

8.       NO RIGHTS AS STOCKHOLDER UNTIL EXERCISE.
         ---------------------------------------

         The Participant shall have no rights as a stockholder with respect to
Shares subject to this Agreement until registration of the Shares in the
Company's share register in the name of the Participant. Except as is expressly
provided in the Plan with respect to certain changes in the capitalization of
the Company, no adjustment shall be made for dividends or similar rights for
which the record date is prior to the date of such registration.

9.       CAPITAL CHANGES AND BUSINESS SUCCESSIONS.
         ----------------------------------------

         The Plan contains provisions covering the treatment of Options in a
number of contingencies such as stock splits and mergers. Provisions in the Plan
for adjustment with respect to stock subject to Options and the related
provisions with respect to successors to the business of the Company are hereby
made applicable hereunder and are incorporated herein by reference.

10.      TAXES.
         -----

         The Participant acknowledges that upon exercise of the Option the
Participant will be deemed to have taxable income measured by the difference
between the then fair market value of the Shares received upon exercise and the
price paid for such Shares pursuant to this Agreement. The Participant
acknowledges that any income or other taxes due from him or her with respect to
this Option or the Shares issuable pursuant to this Option shall be the
Participant's responsibility.

         The Participant agrees that the Company may withhold from the
Participant's

                                      -4-
<PAGE>

remuneration, if any, the appropriate amount of federal, state and local
withholding attributable to such amount that is considered compensation
includable in such person's gross income. At the Company's discretion, the
amount required to be withheld may be withheld in cash from such remuneration,
or in kind from the Shares otherwise deliverable to the Participant on exercise
of the Option. The Participant further agrees that, if the Company does not
withhold an amount from the Participant's remuneration sufficient to satisfy the
Company's income tax withholding obligation, the Participant will reimburse the
Company on demand, in cash, for the amount under-withheld.

11.      PURCHASE FOR INVESTMENT.
         -----------------------

         Unless the offering and sale of the Shares to be issued upon the
particular exercise of the Option shall have been effectively registered under
the Securities Act of 1933, as now in force or hereafter amended (the "1933
Act"), the Company shall be under no obligation to issue the Shares covered by
such exercise unless and until the following conditions have been fulfilled:

         (a)      The person(s) who exercise the Option shall warrant to the
                  Company, at the time of such exercise, that such person(s) are
                  acquiring such Shares for their own respective accounts, for
                  investment, and not with a view to, or for sale in connection
                  with, the distribution of any such Shares, in which event the
                  person(s) acquiring such Shares shall be bound by the
                  provisions of the following legend which shall be endorsed
                  upon the certificate(s) evidencing the Shares issued pursuant
                  to such exercise:

                    "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN
                    ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER
                    THE SECURITIES ACT OF 1933 OR ANY APPLICABLE STATE
                    SECURITIES LAWS. SUCH SHARES MAY NOT BE OFFERED, PLEDGED,
                    SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR
                    AN EXEMPTION THEREFROM AS DETERMINED IN ACCORDANCE WITH THE
                    INVESTOR RIGHTS AGREEMENT AS AMENDED AND RESTATED FROM TIME
                    TO TIME, RESTRICTING THEIR TRANSFER. COPIES OF THE INVESTOR
                    RIGHTS AGREEMENT, AS AMENDED, MAY BE OBTAINED AT NO COST BY

                    CERTIFICATE TO THE SECRETARY OF THE CORPORATION AT THE
                    CORPORATION'S PRINCIPAL PLACE OF BUSINESS. FURTHER, THE
                    DESIGNATIONS, RELATIVE RIGHTS, PREFERENCES AND LIMITATIONS
                    OF EACH CLASS OF STOCK OF THE CORPORATION AND THE VARIATIONS

                    REQUEST OF SUCH HOLDER": and


         (b)      If the Company so requires, the Company shall have received an
                  opinion of its counsel that the Shares may be issued upon such
                  particular exercise in compliance with the 1933 Act without
                  registration thereunder. Without limiting the generality of
                  the foregoing, the Company may delay issuance of the Shares
                  until completion of any action or obtaining of any consent,
                  which the Company deems necessary under any applicable law
                  (including without limitation state securities or "blue sky"
                  laws).

                                    Exhibit A
                                    ---------
                NOTICE OF EXERCISE OF NON-QUALIFIED STOCK OPTION
                         [Form For Unregistered Shares]
To:  OneSoft Corporation

Ladies and Gentlemen:

         I hereby exercise my Non-Qualified Stock Option to purchase ____ shares
(the "Shares") of the common stock, $.001 par value, of OneSoft Corporation (the
"Company"), at the exercise price of $ per share, pursuant to and subject to the
terms of that certain Non-Qualified Stock Option Agreement between the
undersigned and the Company dated this ___ day of ____________.

         I am aware that the Shares have not been registered under the
Securities Act of 1933, as amended (the "1933 Act"), or any state securities
laws. I understand that the reliance by the Company on exemptions under the 1933
Act is predicated in part upon the truth and accuracy of the statements by me in
this Notice of Exercise.

         I hereby represent and warrant that (1) I have been furnished with all
information which I deem necessary to evaluate the merits and risks of the
purchase of the Shares; (2) I have had the opportunity to ask questions
concerning the Shares and the Company and all questions posed have been answered
to my satisfaction; (3) I have been given the opportunity to obtain any
additional information I deem necessary to verify the accuracy of any
information obtained concerning the Shares and the Company; and (4) I have such
knowledge and experience in financial and business matters that I am able to
evaluate the merits and risks of purchasing the Shares and to make an informed
investment decision relating thereto.

         I hereby represent and warrant that I am purchasing the Shares for my
own personal account for investment and not with a view to the sale or
distribution of all or any part of the Shares.

         I understand that because the Shares have not been registered under the
1933 Act, I must continue to bear the economic risk of the investment for an
indefinite time and the Shares cannot be sold unless the Shares are subsequently
registered under applicable federal and state securities laws or an exemption
from such registration requirements is available.

         I agree that I will in no event sell or distribute or otherwise dispose
of all or any part of the Shares unless (1) there is an effective registration
statement under the 1933 Act and applicable state securities laws covering any
such transaction involving the Shares or (2) the Company receives an opinion of
my legal counsel (concurred in by legal counsel for the Company) stating that
such transaction is exempt from registration or the Company otherwise satisfies
itself that such transaction is exempt from registration.

         I consent to the placing of a legend on my certificate for the Shares
stating that the Shares have not been registered and setting forth the
restriction on transfer contemplated
<PAGE>

hereby and to the placing of a stop transfer order on the books of the Company
and with any transfer agents against the Shares until the Shares may be legally
resold or distributed without restriction.

         I understand that at the present time Rule 144 of the Securities and
Exchange Commission (the "SEC") may not be relied on for the resale or
distribution of the Shares by me. I understand that the Company has no
obligation to me to register the sale of the Shares with the SEC and has not
represented to me that it will register the sale of the Shares.

         I understand the terms and restrictions on the right to dispose of the
Shares set forth in the 1997 Employee, Director and Consultant Stock Option Plan
and the Non-Qualified Stock Option Agreement, both of which I have carefully
reviewed. I consent to the placing of a legend on my certificate for the Shares
referring to such restriction and the placing of stop transfer orders until the
Shares may be transferred in accordance with the terms of such restrictions.

         I have considered the Federal, state and local income tax implications
of the exercise of my Option and the purchase and subsequent sale of the Shares.

         I am paying the option exercise price for the Shares as follows:

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

         Please issue the stock certificate for the Shares (check one):

         [_]      to me; or

         [_]      to me and  ________________________,  as joint  tenants with
right of  survivorship  and mail the certificate to me at the following address:
__________________

         My mailing address for shareholder communications, if different from
