ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

    The Certificate of Incorporation of ObjectSpace provides that the liability
of the directors of ObjectSpace to ObjectSpace or any of its stockholders for
monetary damages arising from acts of omissions occurring in their capacity as
directors shall be limited to the fullest extent permitted by the General
Corporation Law of the State of Delaware. This limitation does not apply with
respect to any action in which a director would be liable under Section 174 of
the General Corporation Law of the State of Delaware nor does it apply with
respect to any liability in which a director:

    - breached his duty of loyalty to ObjectSpace or its stockholders;

    - did not act in good faith or, in failing to act, did not act in good
      faith;

    - acted in a manner involving intentional misconduct or a knowing violation
      of law or, in failing to act, shall have acted in a manner involving
      intentional misconduct or a knowing violation of law; or

    - derived an improper personal benefit.

    ObjectSpace's Certificate of Incorporation requires ObjectSpace to indemnify
its directors, officers and employees and former directors, officers and
employees to the fullest extent permitted by the General Corporation Law of the
State of Delaware. Pursuant to the provisions of Section 145 of the General
Corporation Law of the State of Delaware, ObjectSpace has the power to indemnify
any person who was or is a party or is threatened to be made a party to any
threatened, pending, or completed action, suit or proceeding (other than an
action by or in the right of ObjectSpace) by reason of the fact that he is or
was a director, officer, employee or agent of ObjectSpace, against any and all
expenses, judgments, fines and amounts paid in settlement actually and
reasonably incurred in connection with such action, suit or proceeding. The
power to indemnify applies only if such person acted in good faith and in a
manner he reasonably believed to be in the best interest, or not opposed to the
best interest, of ObjectSpace, and with respect to any criminal action or
proceeding, had no reasonable cause to believe his conduct was unlawful.

    The power to indemnify applies to actions brought by or in the right of
ObjectSpace as well, but only to the extent of defense and settlement expenses
and not to any satisfaction of a judgment or settlement of the claim itself and
with the further limitation that in such actions no indemnification

                                      II-1
<PAGE>
shall be made in the event of any adjudication of negligence or misconduct
unless the court, in its discretion, believes that in light of all the
circumstances indemnification should apply.

    The statute further specifically provides that the indemnification
authorized thereby shall not be deemed exclusive of any other rights to which
any such officer or director may be entitled under any bylaws, agreements, vote
of stockholders or disinterested directors, or otherwise.

    Reference is made to the Form of Underwriting Agreement, to be filed as
Exhibit 1.1 to this registration statement, which provides for indemnification
by the underwriters under certain circumstances of the directors and officers of
ObjectSpace signing the registration statement and certain controlling persons
of ObjectSpace against certain liabilities, including those arising under the
Securities Act.

    Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers or persons controlling ObjectSpace
pursuant to the foregoing provisions, ObjectSpace has been advised that in the
opinion of the Securities and Exchange Commission, such indemnification is
against public policy as expressed in the Securities Act and is therefore
unenforceable.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES

    During the past three years, the registrant has issued unregistered
securities to a limited number of persons as described below:

1.  On June 16, 1998, the registrant issued and sold a warrant to purchase up to
    196,000 shares of common stock at a purchase price of $0.01 per share in
    connection with a financing transaction.

2.  On September 4, 1998, the registrant issued and sold 571,429 shares of
    Series A preferred stock to one investor for $3.50 per share, or an
    aggregate of approximately $2.0 million.

3.  On December 30, 1998, the registrant issued and sold an aggregate of
    2,702,703 shares of Series B preferred stock to a total of 6 investors for
    $3.70 per share, or an aggregate of approximately $10.0 million.

4.  On December 30, 1998, the registrant issued and sold a warrant to purchase
    234,595 shares of common stock at a purchase price of $1.32 per share in
    connection with certain financing transactions.

5.  On December 23, 1999, in connection with one of our licensing and
    professional services transactions, the registrant issued a warrant to
    purchase that number of shares of common stock equal to $2.5 million divided
    by the offering price of the common stock in this offering.

6.  As of January 17, 2000, the registrant issued and sold a warrant to purchase
    up to 4,200 shares of common stock at a purchase price of $8.57 per share in
    connection with the registrant's obtaining services from a consultant.

7.  As of March 22, 2000, an aggregate of 322,977 shares of common stock had
    been issued upon exercise of options under the registrant's stock option
    plans.

    On January 14, 2000, the registrant effected a split of its common stock in
the form of a stock dividend of one share of common stock for each share of
common stock outstanding as of that date. On March 30, 2000, the registrant
effected a split of its common stock in the form of a stock dividend of 0.4
shares of common stock for each share of common stock outstanding as of that
date.

    None of the foregoing transactions involved any underwriters, underwriting
discounts or commissions, or any public offering, and the registrant believes
that each transaction was exempt from the registration requirements of the
Securities Act of 1933, as amended, by virtue of Section 4(2) thereof,
Regulation D promulgated thereunder or Rule 701 promulgated under Section 3(b)
thereof, pursuant to compensatory benefit plans and contracts relating to
compensation as provided under such Rule 701. The recipients in such
transactions represented their intention to acquire the securities for
investment only and not with a view to or for sale in connection with any
distribution thereof, and appropriate legends were affixed to the share
certificates and instruments issued in such transactions.

                                      II-2
<PAGE>
All recipients had adequate access, through their relationships with the
registrant, to information about the registrant.

b)  FINANCIAL STATEMENT SCHEDULE

    Financial Statement Schedules are not listed because the information
required to be set forth therein is not applicable or is shown in the financial
statements or notes thereto.

ITEM 17. UNDERTAKINGS

    The undersigned registrant hereby undertakes to provide to the underwriters
at the closing specified in the underwriting agreement, certificates in such
denominations and registered in such names as required by the underwriters to
permit prompt delivery to each purchaser.

    Insofar as indemnification by the registrant for liabilities arising under
the Securities Act of 1933 may be permitted to directors, officers and
controlling persons of the registrant pursuant to the provisions referenced in
Item 14 of this registration statement or otherwise, the registrant has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act of
1933, and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer, or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by a director, officer or controlling person in
connection with the securities being registered hereunder, the registrant will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act of 1933 and will be governed by the final adjudication of such
issue.

    The undersigned registrant hereby undertakes that:

(1) For purposes of determining any liability under the Securities Act of 1933,
    the information omitted from the form of prospectus filed as part of this
    registration statement in reliance upon Rule 430A and contained in a form of
    prospectus filed by the registrant pursuant to Rule 424(b)(1) or
    (4) or 497(h) under the Securities Act of 1933 shall be deemed to be part of
    this registration statement as of the time it was declared effective.

(2) For the purpose of determining any liability under the Securities Act of
    1933, each post-effective amendment that contains a form of prospectus shall
    be deemed to be a new registration statement relating to the securities
    offered therein, and the offering of such securities at that time shall be
    deemed to be the initial bona fide offering thereof.

                                   SIGNATURES


    Pursuant to the requirements of the Securities Act of 1933, the registrant
has duly caused this First Amendment to the Registration Statement to be signed
on its behalf by the undersigned, thereunto duly authorized, in the city of

                          CERTIFICATE OF INCORPORATION

                                       OF

                                OBJECTSPACE, INC.

         THIRD:  The purpose of the Corporation is to engage in any lawful act
or activity for which a corporation may be organized under the Delaware

         FOURTH: The total number of shares of stock which the Corporation
shall have authority to issue is 21,000,000 shares of capital stock,
classified as (i) 20,000,000 shares of common stock, $.01 par value ("Common
Stock"), and (ii) 1,000,000 shares of preferred stock, $1.00 par value
("Preferred Stock").

         The designations and the powers, preferences, rights, qualifications,
limitations, and restrictions of the Preferred Stock and Common Stock are as
follows:

         1.       PROVISIONS RELATING TO THE PREFERRED STOCK.

or resolutions providing for the issue of such class or series adopted, as
hereinafter prescribed, by the entire board of directors of the Corporation
("Board of Directors") or by any duly designated committee thereof
("Committee").

         (b) Authority is hereby expressly granted to and vested in the Board of
Directors or Committee to authorize the issuance of the Preferred Stock from
time to time in one or more classes or series, and with respect to each class or
series of the Preferred Stock, to fix and state by the resolution or resolutions
from time to time adopted providing for the issuance thereof the following:

                  (i) whether or not the class or series is to have voting
rights, full, special, or limited, or is to be without voting rights, and
whether or not such class or series is to be entitled to vote as a separate
class either alone or together with the holders of one or more other classes
or series of stock;



<PAGE>


                  (ii) the number of shares to constitute the class or series
and the designations thereof;

                  (iii) the preferences, and relative, participating, optional,
or other special rights, if any, and the qualifications, limitations, or
restrictions thereof, if any, with respect to any class or series;

                  (iv) whether or not the shares of any class or series shall be
redeemable at the option of the Corporation or the holders thereof or upon the
happening of any specified event, and, if redeemable, the redemption price or
prices (which may be payable in the form of cash, notes, securities, or other
property), and the time or times at which, and the terms and conditions upon
which, such shares shall be redeemable and the manner of redemption;

                  (v) whether or not the shares of a class or series shall be
subject to the operation of retirement or sinking funds to be applied to the
purchase or redemption of such shares for retirement, and, if such retirement or
sinking fund or funds are to be established, the annual amount thereof, and the
terms and provisions relative to the operation thereof;

                  (vi) the dividend rate, whether dividends are payable in cash,
stock of the Corporation, or other property, the conditions upon which and the
times when such dividends payable on any other class or classes or series of
stock, whether or not such dividends shall be cumulative or noncumulative, and
if cumulative, the date or dates from which such dividends shall accumulate;

                  (vii) the preferences, if any, and the amounts thereof which
the holders of any class or series thereof shall be entitled to receive upon the
voluntary or involuntary dissolution of, or upon any distribution of the assets
of, the Corporation;

                  (viii) whether or not the shares of any class or series, at
the option of the Corporation or the holder thereof or upon the happening of any
specified event, shall be convertible into or exchangeable for, the shares or
any other class or classes or of any other series of the same or any other class
or classes of stock, securities, or other property of the Corporation and the
conversion price or prices or ratio or ratios or the rate or rates at which such
exchange may be made, with such adjustments, if any, as shall be stated and
expressed or provided for in such resolution or resolutions; and

                  (ix) such other special rights and protective provisions with
respect to any class or series as may to the Board of Directors or Committee
deem advisable.

         (c) The shares of each class or series of the Preferred Stock may vary
from the shares of any other class or series thereof in any or all of the
foregoing respects. The Board of Directors or Committee may increase the number
of shares of the Preferred Stock designated for any existing class or series by
a resolution adding to such class or series authorized and unissued shares of
the


                                      -2-
<PAGE>


Preferred Stock not designated for any other class or series. The Board of
Directors or Committee may decrease the number of shares of the Preferred
Stock designated for any existing class or series by a resolution subtracting
from such class or series authorized and unissued shares of the Preferred
Stock designated for such existing class or series, and the shares so
subtracted shall become authorized, unissued, and undesignated shares of the
Preferred Stock. The number of authorized shares of Preferred Stock may be
increased or decreased (but not below the number of shares thereof then
outstanding) by the affirmative vote of the holders of a majority of the
Common Stock, without a vote of the holders of the Preferred Stock, or any
series thereof, unless a vote of any such holders is required pursuant to the
terms fixed therefor in the resolution or resolutions providing for the
issuance of such class or series adopted by the Board of Directors or any
Committee.

         2.       PROVISIONS RELATING TO THE COMMON STOCK.

         (a) Each share of Common Stock of the Corporation shall have identical
rights and privileges in every respect. The holders of shares of Common Stock
shall be entitled to vote upon all matters submitted to a vote of the
stockholders of the Corporation and shall be entitled to one vote for each share
of Common Stock held.

         (b) Subject to the prior rights and preferences, if any, applicable to
shares of the Preferred Stock or any series thereof, the holders of shares of
the Common Stock shall be entitled to receive such dividends (payable in cash,
stock, or otherwise) as may be declared thereon by the Board of Directors or
Committee at any time and from time to time out of any funds of the Corporation
legally available therefor.

         (c) In the event of any voluntary or involuntary liquidation,
dissolution, or winding-up of the Corporation, after distribution in full of the
preferential amounts, if any, to be distributed to the holders of shares of the
Preferred Stock or any series thereof, the holders of shares of the Common Stock
shall be entitled to receive all of the remaining assets of the Corporation
available for distribution to its stockholders, ratably in proportion to the
number of shares of the Common Stock held by them. A liquidation, dissolution,
or winding-up of the Corporation, as such terms are used in this paragraph (c),
shall not be deemed to be occasioned by or to include any consolidation or
merger of the Corporation with or into any other corporation or corporations or
other entity or a sale, lease, exchange, or conveyance of all or a part of the
assets of the Corporation.

         3.       GENERAL.

         (a) Subject to the foregoing provisions of this Certificate of
Incorporation and the applicable provisions of the DGCL, the Corporation may
issue shares of its Preferred Stock and Common Stock from time to time for such
consideration (not less than the par value thereof) as may be fixed by the Board
of Directors or Committee, which is expressly authorized to fix the same in its
absolute and uncontrolled discretion subject to the foregoing conditions. Shares
so issued for which the consideration shall have been paid or delivered to the
Corporation shall be deemed fully paid stock and shall not be liable to any
further call or assessment thereon, and the holders of such shares shall not be
liable for any further payments in respect of such shares.


                                      -3-
<PAGE>


         (b) The Corporation shall have authority to create and issue rights and
options entitling their holders to purchase shares of the Corporation's capital
stock of any class or series or other securities of the Corporation, and such
rights and options shall be evidenced by instrument(s) approved by the Board of
Directors or Committee. The Board of Directors or Committee shall be empowered
to set the exercise price, duration, times for exercise, and other terms of such
options or rights; PROVIDED, HOWEVER, that the consideration to be received for
any shares of capital stock subject thereto shall not be less than the par value
thereof.

         FIFTH: The number of directors constituting the Board of Directors
shall be fixed by, or in the manner provided in, the bylaws of the Corporation,
provided that such number shall be no less than one (plus such number of
directors as may be elected from time to time pursuant to the terms of any
series of Preferred Stock that may be issued and outstanding from time to time)
and until changed in accordance with the manner prescribed by the bylaws shall
be two (2).

         The directors of the Corporation, whether now serving as such or
hereafter elected (exclusive of directors who are elected pursuant to the
terms of, and serve as representatives of the holders of, any series of
Preferred Stock), shall be referred to herein as "Classified Directors" and
shall be divided into three classes, with the first class referred to herein
as "Class 1," the second class as "Class 2," and the third class as "Class 3."
If the total number of Classified Directors equals a number divisible by
three, then the number of directors in each of Class 1, Class 2, and Class 3
shall be that number of directors equal to the total number of directors
divided by three. If, however, the total number of Classified Directors equals
a number that is not divisible by three, each such class of directors shall
consist of that number of directors as nearly equal in number as reasonably
possible to the total number of directors divided by three, as determined by
the Board of Directors in advance of each respective election of directors by
holders of shares of capital stock of the Corporation then entitled to vote in
such election. The term of office of the initial Class 1 directors shall
expire at the 1998 annual meeting of stockholders, the term of office of the
initial Class 2 directors shall expire at the 1999 annual meeting of
stockholders and the term of office of the initial Class 3 directors shall
expire at the 2000 annual meeting of stockholders, with each director to hold
office until his successor shall have been duly elected and qualified. At each
annual meeting of stockholders, commencing with the 1998 annual meeting,
directors elected to succeed those directors whose terms then expire shall be
elected for a term of office to expire at the third succeeding annual meeting
of stockholders after their election, with each director to hold office until
his successor shall have been duly elected and qualified.

         Notwithstanding the foregoing, whenever the holders of any one or more
classes or series of Preferred Stock issued by the Corporation shall have the
right, voting separately by series or by class (excluding holders of Common
Stock), to elect directors, the election, term of office, filling of vacancies,
and other features of such directorships shall be governed by the terms of this
Certificate of Incorporation (including any amendment to this Certificate of
Incorporation that designates a series of Preferred Stock), and such directors
so elected by the holders of Preferred Stock shall not be divided into classes
pursuant to this Article FIFTH unless expressly provided by such terms.


                                      -4-
<PAGE>


         Any or all Classified Directors may be removed, with cause, upon the
affirmative vote of the holders of a majority of the outstanding shares of each
class of capital stock of the Corporation then entitled to vote at an election
of such Classified Directors. Except as may otherwise be provided by law, cause
for removal shall exist only if the director whose removal is proposed (a) has
been convicted of a felony by a court of competent jurisdiction and such
conviction is no longer subject to direct appeal, (b) has been adjudged by a
court of competent jurisdiction to be liable for gross negligence or misconduct
in the performance of his duties to the Corporation in a matter of substantial
importance to the Corporation, and such adjudication has become final and
non-appealable, or (c) has missed twelve consecutive meetings of the Board of
Directors.

         The name and address of each person who is to serve as a director until
his term of office expires (as described below) or until his successor be
elected and qualified, is as follows, and such person shall serve in the Class
designated:

       NAME                    MAILING ADDRESS                  CLASS
     --------                 -----------------                -------

    Graham Glass              14850 Quorum Drive                  2
                              Suite 500
                              Dallas, Texas  75240

    David Norris              14850 Quorum Drive                  3
                              Suite 500
                              Dallas, Texas  75240

         SIXTH: All the powers of the Corporation, insofar as the same may be
lawfully vested by this Certificate of Incorporation in the Board of Directors,
are hereby conferred upon the Board of Directors. In furtherance and not in
limitation of that power, the Board of Directors shall have the power, upon the
affirmative vote of at least two-thirds (2/3) of the Classified Directors then
serving to make, adopt, alter, amend, and repeal from time to time the bylaws of
the Corporation and to make from time to time new bylaws of the Corporation
(subject to the right of the stockholders entitled to vote thereon to adopt,
alter, amend, and repeal bylaws made by the Board of Directors or to make new
bylaws); PROVIDED, HOWEVER, that the stockholders of the Corporation shall be
entitled to adopt, alter, amend, or repeal bylaws made by the Board of Directors
or to make new bylaws solely upon the affirmative vote of the holders of at
least two-thirds (2/3) of the outstanding shares of each class of capital stock
of the Corporation then entitled to vote thereon.

         SEVENTH: Whenever a compromise or arrangement is proposed between this
Corporation and its creditors or any class of them and/or between this
Corporation and its stockholders or any class of them, any court of equitable
jurisdiction within the State of Delaware may, on the application in a summary
way of this Corporation or of any creditor or stockholder thereof or on the
application of any receiver or receivers appointed for this corporation under
Section 291 of Title 8 of the Delaware Code or on the application of trustees in
dissolution or of any receiver or receivers appointed for this Corporation under
Section 279 of Title 8 of the Delaware Code order a meeting of the creditors or
class of creditors, and/or of the stockholders or class of stockholders of this
Corporation,


                                      -5-
<PAGE>


as the case may be, to be summoned in such manner as the said court directs.
If a majority in number representing three-fourths in value of the creditors
of class of creditors, and/or of the stockholders or class of stockholders of
this Corporation, as the case may be, agree to any compromise or arrangement
and to any reorganization of this Corporation as consequence of such
compromise or arrangement, the said compromise or arrangement and the said
reorganization shall, if sanctioned by the court to which the said application
has been made, be binding on all the creditors or class of creditors, and/or
on all the stockholders or class of stockholders, of this Corporation, as the
case may be, and also on this Corporation.

         EIGHTH: No director of the Corporation shall be liable to the
Corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director, except for liability (i) for any breach of the director's
duty of loyalty to the Corporation or its stockholders, (ii) for acts or
omissions not in good faith or that involve intentional misconduct or a
knowing violation of law, (iii) under Section 174 of the DGCL, or (iv) for any
transaction from which the director derived an improper personal benefit. If
the DGCL hereafter is amended to authorize the further elimination or
limitation of the liability of directors, then the liability of a director of
the Corporation, in addition to the limitation on personal liability provided
herein, shall be limited to the fullest extent permitted by the amended DGCL.
Any repeal or modification of this Article by the stockholders of the
Corporation shall be prospective only and shall not adversely affect any
limitation of the personal liability of a director of the Corporation existing
at the time of such repeal or modification.

         NINTH: The Corporation shall indemnify any person who was, is, or is
threatened to be made a party to a proceeding (as hereinafter defined) by
reason of the fact that he or she (i) is or was a director or officer of the
Corporation or (ii) while a director or officer of the Corporation, is or was
serving at the request of the Corporation as a director, officer, partner,
venturer, proprietor, trustee, employee, agent or similar functionary of
another foreign or domestic corporation, partnership, joint venture, sole
proprietorship, trust, employee benefit plan, or other enterprise, to the
fullest extent permitted under the DGCL, as the same exists or may hereafter
be amended.

         Such rights shall be a contract right and as such shall run to the
benefit of any director or officer who is elected and accepts the position of
director or officer of the Corporation or elects to continue to serve as a
director or officer of the Corporation while this Article NINTH is in effect.
Any repeal or amendment of this article NINTH shall be prospective only and
shall not limit the rights of any such director or officer or the obligations of
the Corporation with respect to any claim arising from or related to the
services of such director or officer in any of the foregoing capacities prior to
any such repeal or amendment to this Article NINTH. Such right shall include the
right to be paid by the Corporation expenses incurred in defending any such
proceeding in advance of its final disposition to the maximum extent permitted
under the DGCL.

         If a claim for indemnification hereunder is not paid in full by the
Corporation within sixty (60) days after a written claim has been received by
the Corporation, the claimant may at any time thereafter bring suit against the
Corporation to recover the unpaid amount of the claim, and if successful in
whole or in part, the claimant shall also be entitled to be paid the expenses of
prosecuting such claim. It shall be a defense to any such action that such
indemnification or


                                      -6-
<PAGE>


advancement of costs of defense are not permitted under the DGCL, but the
burden of proving such defense shall be on the Corporation. Neither the
failure of the Corporation (including the Board of Directors or any Committee
thereof, independent legal counsel, or stockholders) to have made its
determination prior to the commencement of such action that indemnification
of, or advancement of costs of defense to, the claimant is permissible in the
circumstances nor an actual determination by the Corporation (including the
Board of Directors or any Committee thereof, independent legal counsel, or
stockholders) that such indemnification or advancement is not permissible
shall be a defense to the action or create a presumption that such
indemnification by the Corporation is not permissible.

         In the event of the death of any person having rights of
indemnification under the foregoing provisions, such right shall inure to the
benefit of his or her heirs, executors, administrators, and personal
representatives. The rights conferred above shall not be exclusive of any
other right which any person may have or hereafter acquire under any statute,
bylaw, resolution of stockholders or directors, agreement, or otherwise.

         The Corporation may additionally indemnify any employee or agent of the
Corporation to the fullest extent permitted by law.

         As used herein, the term "proceeding" means any threatened, pending, or
completed action, suit, or proceeding, whether civil, criminal, administrative,
arbitrative, or investigative, any appeal in such an action, suit, or
proceeding, and any inquiry or investigation that could lead to such an action,
suit, or proceeding.

         TENTH: The Corporation expressly elects to be governed by Section 203
of the DGCL.

         ELEVENTH: Special meetings of stockholders of the Corporation may only
be called by the Board of Directors pursuant to a resolution adopted by a
majority of the Classified Directors then serving, by the Chairman of the Board
of Directors, or by any holder or holders of at least twenty-five percent (25%)
of the outstanding shares of capital stock of the Corporation then entitled to
vote on any matter for which the respective special meeting is being called.

         TWELFTH: Notwithstanding any other provisions of this Certificate of
Incorporation or any provision of law which might otherwise permit a lesser vote
or no vote, the affirmative vote of the holders of at least two-thirds (2/3) of
the outstanding shares of each class of capital stock of the Corporation then
entitled to vote thereon shall be required to amend, alter, or repeal any one or
more of Articles FIFTH, SIXTH, EIGHTH, NINTH, TENTH, ELEVENTH, TWELFTH AND
THIRTEENTH of this Certificate of Incorporation.

         THIRTEENTH: Any action required to be taken at any annual or special
meeting of holders of Common Stock, or any action which may be taken at any
annual or special meeting of such stockholders, may be taken without a meeting,

                                    EXHIBIT A


         FOURTH: The total number of shares of stock which the Corporation shall

         1.       PROVISIONS RELATING TO THE PREFERRED STOCK.

         (a)      The Preferred Stock may be issued from time to time in one
or more classes or series, the shares of each class or series to have such

series adopted, as hereinafter prescribed, by the entire board of directors
of the Corporation ("Board of Directors") or by any duly designated committee
thereof ("Committee").

         (b)      Authority is hereby expressly granted to and vested in the
Board of Directors or Committee to authorize the issuance of the Preferred
Stock from time to time in one or more classes or series, and with respect to
each class or series of the Preferred Stock, to fix and state by the
resolution or resolutions from time to time adopted providing for the
issuance thereof the following:

                  (i) whether or not the class or series is to have voting
rights, full, special, or limited, or is to be without voting rights, and
whether or not such class or series is to be entitled to vote as a separate
class either alone or together with the holders of one or more other classes
or series of stock;

                  (ii) the number of shares to constitute the class or series
and the designations thereof;

                  (iii) the preferences, and relative, participating,
optional, or other special rights, if any, and the qualifications,
limitations, or restrictions thereof, if any, with respect to any class or
series;

                  (iv) whether or not the shares of any class or series shall
be redeemable at the option of the Corporation or the holders thereof or upon
the happening of any specified event, and, if redeemable, the redemption
price or prices (which may be payable in the form of cash, notes, securities,

conditions upon which, such shares shall be redeemable and the manner of
redemption;

                  (v) whether or not the shares of a class or series shall be

purchase or redemption of such shares for


                                       3
<PAGE>


retirement, and, if such retirement or sinking fund or funds are to be
established, the annual amount thereof, and the terms and provisions relative
to the operation thereof;

                  (vi) the dividend rate, whether dividends are payable in cash,
stock of the Corporation, or other property, the conditions upon which and the
times when such dividends payable on any other class or classes or series of
stock, whether or not such dividends shall be cumulative or noncumulative, and
if cumulative, the date or dates from which such dividends shall accumulate;

                  (vii) the preferences, if any, and the amounts thereof which
the holders of any class or series thereof shall be entitled to receive upon the
voluntary or involuntary dissolution of, or upon any distribution of the assets
of, the Corporation;

                  (viii) whether or not the shares of any class or series, at
the option of the Corporation or the holder thereof or upon the happening of any
specified event, shall be convertible into or exchangeable for, the shares or
any other class or classes or of any other series of the same or any other class
or classes of stock, securities, or other property of the Corporation and the
conversion price or prices or ratio or ratios or the rate or rates at which such
exchange may be made, with such adjustments, if any, as shall be stated and
expressed or provided for in such resolution or resolutions; and

                  (ix) such other special rights and protective provisions with
respect to any class or series as may to the Board of Directors or Committee
deem advisable.

         (c) The shares of each class or series of the Preferred Stock may vary
from the shares of any other class or series thereof in any or all of the
foregoing respects. The Board of Directors or Committee may increase the number
of shares of the Preferred Stock designated for any existing class or series by
a resolution adding to such class or series authorized and unissued shares of
the Preferred Stock not designated for any other class or series. The Board of
Directors or Committee may decrease the number of shares of the Preferred Stock
designated for any existing class or series by a resolution subtracting from
such class or series authorized and unissued shares of the Preferred Stock
designated for such existing class or series, and the shares so subtracted shall
become authorized, unissued, and undesignated shares of the Preferred Stock. The
number of authorized shares of Preferred Stock may be increased or decreased
(but not below the number of shares thereof then outstanding) by the affirmative
vote of the holders of a majority of the Common Stock, without a vote of the
holders of the Preferred Stock, or any series thereof, unless a vote of any such
holders is required pursuant to the terms fixed therefor in the resolution or
resolutions providing for the issuance of such class or series adopted by the
Board of Directors or any Committee.

         2.       PROVISIONS RELATING TO THE COMMON STOCK.

         (a) Each share of Common Stock of the Corporation shall have identical
rights and privileges in every respect. The holders of shares of Common Stock
shall be entitled to vote upon


                                       4
<PAGE>


all matters submitted to a vote of the stockholders of the Corporation and
shall be entitled to one vote for each share of Common Stock held.

         (b) Subject to the prior rights and preferences, if any, applicable to
shares of the Preferred Stock or any series thereof, the holders of shares of
the Common Stock shall be entitled to receive such dividends (payable in cash,
stock, or otherwise) as may be declared thereon by the Board of Directors or
Committee at any time and from time to time out of any funds of the Corporation
legally available therefor.

         (c) In the event of any voluntary or involuntary liquidation,
dissolution, or winding-up of the Corporation, after distribution in full of the
preferential amounts, if any, to be distributed to the holders of shares of the
Preferred Stock or any series thereof, the holders of shares of the Common Stock
shall be entitled to receive all of the remaining assets of the Corporation
available for distribution to its stockholders, ratably in proportion to the
number of shares of the Common Stock held by them. A liquidation, dissolution,
or winding-up of the Corporation, as such terms are used in this paragraph (c),
shall not be deemed to be occasioned by or to include any consolidation or
merger of the Corporation with or into any other corporation or corporations or
other entity or a sale, lease, exchange, or conveyance of all or a part of the
assets of the Corporation.

         3.       GENERAL.

         (a) Subject to the foregoing provisions of this Certificate of
Incorporation and the applicable provisions of the DGCL, the Corporation may
issue shares of its Preferred Stock and Common Stock from time to time for such
consideration (not less than the par value thereof) as may be fixed by the Board
of Directors or Committee, which is expressly authorized to fix the same in its
absolute and uncontrolled discretion subject to the foregoing conditions. Shares
so issued for which the consideration shall have been paid or delivered to the
Corporation shall be deemed fully paid stock and shall not be liable to any
further call or assessment thereon, and the holders of such shares shall not be
liable for any further payments in respect of such shares.

         (b) The Corporation shall have authority to create and issue rights and
options entitling their holders to purchase shares of the Corporation's capital
stock of any class or series or other securities of the Corporation, and such
rights and options shall be evidenced by instrument(s) approved by the Board of
Directors or Committee. The Board of Directors or Committee shall be empowered
to set the exercise price, duration, times for exercise, and other terms of such
options or rights; PROVIDED, HOWEVER, that the consideration to be received for
any shares of capital stock subject thereto shall not be less than the par value
thereof.

                            MASTER SERVICES AGREEMENT

This MASTER SERVICES AGREEMENT ("Agreement") is effective as of the 6th day
of August, 1999 (the "Effective Date") by and between GALILEO INTERNATIONAL,
L.L.C. ("Galileo"), a Delaware limited liability company and wholly owned
subsidiary of Galileo International, Inc., with offices at 9700 West Higgins
Road, Rosemont, Illinois 60018, AND OBJECTSPACE, INC., a Delaware
corporation, whose mailing address is 14850 Quorum Drive, Suite 500, Dallas,
Texas 75240 ("ObjectSpace").

                                    RECITALS

     A. ObjectSpace is in the business of creating and deploying advanced
technology solutions that leverage existing object-oriented technology and
providing consulting, training, and software products.

     B. Galileo desires to obtain such services from ObjectSpace pursuant to
the terms of this Agreement.

     Therefore, in consideration of the mutual covenants contained herein,
Galileo and ObjectSpace agree as follows:

1. SERVICES

     A.   ObjectSpace shall provide software and/or professional or technical
          services (collectively referred to herein as the "Services") described
          in one or more Task Orders negotiated and signed from time to time by
          authorized representatives of both parties. Each Task Order shall set
          forth, at a minimum, a description of the Services to be performed,
          the number of ObjectSpace's personnel assigned to the project
          (including their names), the duration of each individual's assignment,
          the project deliverables, a schedule for completing the project,
          reporting requirements, a project manager for each party, software
          testing and acceptance criteria and license and maintenance fees (if
          applicable), the fees for the Services to be performed, identification
          of the portions of any software to be delivered that are New Software
          and Other Software, as defined herein, and, to the extent that
          software owned by third parties is a portion of the software to be
          delivered to Galileo pursuant to a Task Order, the Task Order shall
          also include an identification of such third party software and a
          specification of the manner in which Galileo has or can obtain rights
          to use such third party software including additional costs, as
          applicable. A specimen Task Order is attached hereto as Exhibit A.
          ObjectSpace shall have the right to accept or decline any proposed
          Task Order.

     B.   Galileo shall have the right to request modifications to the scope of
          the Task Order by notifying ObjectSpace of the nature of the proposed
          change. For each proposed change or addition, ObjectSpace agrees to
          provide to Galileo, at no additional charge, an analysis of such
          change or addition, which shall include the following: (1) An estimate
          of the time and materials cost for each such change; and (2) An
          estimate of the effect such change would have on the project,
          including the impact on outstanding and future deliverables and the
          related delivery dates for such deliverables. Any changes in the
          scope, price, schedule, or requirements of a project must be evidenced
          by a written amendment to the Task Order that is executed by
          authorized representatives of both parties.

     C.   The methods, details, and means of performing the Services shall be
          determined jointly by ObjectSpace and Galileo, subject to Galileo's
          right to assure satisfactory results by exercising its rights to
          inspect, stop work, make recommendations regarding details of the
          work, and request modifications to the scope of the Task Order. The
          Services shall be performed either at Galileo's or ObjectSpace's
          premises, as agreed. If Services are performed at Galileo's premises,
          Galileo shall provide ObjectSpace's personnel with appropriate
          workspace, equipment, and services, and ObjectSpace's personnel shall
          observe Galileo's security and safety policies.


                                                                     Page 1 of 9

<PAGE>

     D.   Galileo shall provide appropriate cooperation and access to key
          personnel to enable ObjectSpace to perform the Services.

2. PERSONNEL

     A.   The person(s) retained by ObjectSpace and actively engaged in the
          provision of Services under this Agreement shall be identified in the
          applicable Task Order by name, title or position and responsibilities.
          Galileo shall have the right to approve all Personnel providing
          Services. If Galileo reasonably determines that any of Consultant's
          personnel are not appropriate for the work being performed based on
          their skills, background, or experience, ObjectSpace shall make a good
          faith effort to assign other qualified personnel.

     B.   ObjectSpace may not utilize subcontractors to provide the Services
          without Galileo's prior written consent. Each subcontractor shall
          execute a written agreement whereby he agrees to be bound by the terms
          of this Agreement.

     C.   All persons providing Services to Galileo under this Agreement shall
          at all times be employees of ObjectSpace and not of Galileo. It is the
          intent of the parties that ObjectSpace at all times shall be an
          independent contractor with full and complete responsibility for all
          of its employees, representatives, and subcontractors (hereafter
          "Personnel"), including, Without limitation, payment of all
          payroll-related taxes. Nothing in this Agreement shall be interpreted
          to create or establish the relationship of employer and employee
          between Galileo and ObjectSpace or any of its Personnel.

3. SOFTWARE DELIVERY AND TESTING

     A.   To the extent the Services specified in a particular Task Order
          contemplate the creation of any new, custom software that does not
          exist in the current product offerings of ObjectSpace or any third
          party and that is to be created only for Galileo's benefit ("New
          Software"), the parties shall agree upon criteria and methods for
          testing and acceptance of such New Software. Delivery of such New
          Software shall include the New Software itself in object code format,
          the source code for the New Software, and any related documentation,
          flow charts, design documents, record and file layouts, user and
          maintenance manuals, and any other materials deemed necessary by
          Galileo to perform the acceptance testing specifically and solely
          associated with the New Software (the "Software Deliverables"). The
          parties hereto expressly agree that the Software Deliverables shall
          only include information, code and documentation associated with New
          Software developed for Galileo as a result of a Task Order and shall
          not include (1) any preexisting software owned by ObjectSpace or any
          third party or (2) other software created by ObjectSpace but not
          specifically for Galileo (collectively, the "0ther Software") that may
          be used in conjunction with the New Software created for Galileo.
          Galileo shall only receive executable code and user level
          documentation, where applicable and available for all Other Software.

     B.   Upon delivery of the Software Deliverables, ObjectSpace shall assist
          Galileo in testing the New Software, and take all reasonable steps to
          correct any defects identified by Galileo.

4. TERM

     This Agreement shall commence on the Effective Date and expire upon the
     parties' completion of all obligations set forth under this Agreement or
     August 5, 2000, whichever occurs first (such period being referred to
     herein as the "Term"). This Agreement may be earlier terminated in
     accordance with Section 18 hereof. This Agreement may not be renewed or
     extended except by written agreement executed by both parties. Any
     obligations that survive the expiration or termination of this Agreement
     shall continue thereafter in full force and effect.

5. PROJECT MANAGERS


                                                                     Page 2 of 9

<PAGE>

     ObjectSpace and Galileo shall each designate, prior to the commencement of
     work under this Agreement, a project manager who shall have responsibility
     for conveying decisions on behalf of the respective parties under this
     Agreement. Such designated project managers shall be identified in the
     applicable Task Order. All correspondence and reports pertaining to this
     Agreement shall be initiated by and addressed to the respective project
     managers, except that notices under this Agreement shall be addressed as
     specified under Notices, below.

6. REPORTS AND DOCUMENTATION

     As specified in the applicable Task Order (or as otherwise agreed by
     Galileo and ObjectSpace in writing), ObjectSpace shall provide to Galileo
     written reports of the Services (the "Reports").

7. PROPRIETARY RIGHTS

     A.   ObjectSpace hereby assigns to Galileo all right, title, and Interest
          in and to the New Software, the Software Deliverables, Reports, and
          other ideas, Inventions, discoveries, improvements, designs, computer
          programs, modules, products and related documentation and works of
          authorship, including any modifications or enhancements thereto, and
          other intellectual property created or conceived wholly or in part by
          ObjectSpace or Its Personnel In connection with performing Services
          pursuant to this Agreement, whether alone or in cooperation with
          Galileo or any other third party that are embodied in New Software
          (collectively, the "Work Product"). Galileo shall have the right to
          obtain and to hold exclusively in Galileo's own name all rights to any
          copyrights in any copyrightable materials embodied in the Work
          Product, and any extensions and renewals thereof. ObjectSpace agrees,
          at the request of Galileo and for no additional consideration, to
          execute such documents and perform such other acts as Galileo deems
          necessary to effectuate the transfer of rights hereunder.

     B.   ObjectSpace hereby agrees and acknowledges that neither ObjectSpace
          nor its Personnel shall have any right to: (1) use, reproduce, modify,
          prepare derivative works from, distribute, transmit or otherwise
          exploit the Work Product by any means whatsoever, or (2) develop, use,
          or distribute works that are similar or identical (in function,
          structure, sequence, or organization) to the Work Product, except as
          may be necessary to perform the Services.

     C.   The term Work Product shall not be construed to include, and
          ObjectSpace shall retain all rights, title, and interest in: (1) the
          Other Software or any other software program(s) and documentation
          owned or distributed by ObjectSpace that is developed independently by
          ObjectSpace outside the scope of the Services; (2) any object oriented
          subroutines that are used in developing or that are embodied in the
          Work Product (excluding any Galileo Confidential Information); and (3)
          any tools or utilities developed by or on behalf of ObjectSpace (the
          foregoing being hereinafter collectively referred to as "Proprietary
          Materials"). ObjectSpace grants to Galileo a non-exclusive,
          nontransferable, perpetual license to use such Proprietary Materials
          that are incorporated into the Work Product solely for the operation
          of the New Software (other than the "Voyager" software, which shall be
          licensed pursuant to a separate license agreement).

     C.   Notwithstanding the foregoing, ObjectSpace may, except as otherwise
          provided herein, freely use the "residuals" from the Work Product,
          provided that ObjectSpace shall maintain the confidentiality of
          Galileo's Confidential Information. (The term "residuals" shall mean
          the Work Product in nontangible form (i.e., not in written or other
          documentary form, including tape or disk) that may be retained in the
          memories of ObjectSpace Personnel who have had access to or assisted
          in development of the Work Product, including know-how, ideas, or
          techniques contained therein.)

     D.   During the term of this Agreement, and for a period of 12 months
          thereafter, ObjectSpace shall not, without Galileo's prior written
          consent, assign any ObjectSpace Personnel who have performed Services
          hereunder to perform, for any entity listed on Exhibit B, services
          similar to those performed by such Personnel hereunder.

8. REPRESENTATIONS AND WARRANTIES


                                                                     Page 3 of 9

          herein. The term "Year 2000 Compliant" or "Year 2000 Compliance" shall
          mean that each Product, when used in accordance with its applicable
          documentation, shall be capable upon installation of accurately
          processing (including, but not limited to, providing, receiving,
          calculating, comparing and sequencing of data) date and daterelated
          data from, into, and between the twentieth and twenty-first centuries,
          including the years 1999 and 2000, and leap year calculations.

          Year 2000 Compliant until December 31, 2003. ObjectSpace shall
          promptly repair any non-compliant Products and documentation. If
          ObjectSpace is unable to rectify a Year 2000 noncompliance issue after
          reasonable efforts, ObjectSpace hereby grants Galileo permission to
          modify the Products, or any portion thereof, to bring the Product(s)
          into Year 2000 Compliance.

     C.   ObjectSpace represents and warrants that it has obtained all written
          assignments and consents from any Personnel or other third party as
          may be necessary to effectuate fully the transfer and assignment of

          are necessary or appropriate under any agreements concerning any of
          the Work Product in order for the transfer and assignment of any of
          the Work Product under this Agreement to be legally effective in the
          United States, India or any other relevant jurisdiction.

     D.   ObjectSpace warrants that the Work Product, and any modifications or
          enhancements thereto, shall not infringe any intellectual property or
          other proprietary right of a third party of which ObjectSpace has
          direct knowledge, and that ObjectSpace shall not enter into any
          agreement or take any action that would conflict with the proprietary
          rights granted to Galileo hereunder.

     E.   ObjectSpace represents and warrants that, for a period of 90 days
          following the successful completion of the acceptance testing
          procedures specified in Section 3 above, the Software Deliverables
          shall conform to Galileo's specifications and requirements.

     F.   ObjectSpace represents and warrants that neither ObjectSpace nor any
          Personnel have any obligations to prior employers or others relating
          to proprietary or confidential information or any inventions or
          discoveries relating to the business of Galileo, and neither
          ObjectSpace nor any Personnel is bound by any restriction, agreement,
          judgment or other limitation limiting ObjectSpace's ability to enter
          into this Agreement or to carry out its terms or shall engage in any
          activity or take any action that would be In conflict with or that
          would result in a breach or violation of any such restriction,
          agreement, judgment or other limitation.

9. FEES

     A.   In consideration of performance of the Services pursuant to the terms
          of this Agreement, Galileo shall pay to ObjectSpace the amounts
          specified in the applicable Task Order. Unless otherwise provided in

          hourly basis, ObjectSpace agrees to keep complete and accurate books
          and records of the actual number of hours worked in performing the
          Services. Galileo shall pay such invoices within thirty (30) days of
          receipt by Galileo. During the term of this Agreement and for a period
          of one year following expiration or termination for any reason,
          Galileo or its representative may, upon reasonable prior notice,
          inspect the aforesaid books and records and make copies thereof. Any
          such audit shall be at the expense of Galileo.


                                                                     Page 4 of 9

     telephone and rental car, actually incurred by ObjectSpace or Personnel in
     connection with Services related travel preapproved by Galileo, up to the
     maximum(s), if any, set forth in the applicable Task Order. Such expenses
     shall be reimbursed by Galileo only upon submission by ObjectSpace of
     written expense reports documenting such expenses with receipts for all
     expenditures greater than twenty-five dollars ($25.00). Except for the
     travel-related expenses specified in this Section 10, Galileo shall not be
     responsible for any out-of-pocket expenses of ObjectSpace or Personnel,
     unless otherwise provided in the applicable Task Order.

11. TAXES

     A.   Galileo shall pay any United States sales or use taxes (except for any
          tax levied upon or measured by ObjectSpace's gross receipts) imposed
          by any taxing authority and required to be paid by ObjectSpace or
          Galileo as a result of the services provided to Galileo under this
          Agreement. Galileo shall not be liable for any tax levied upon or
          measured by the income of ObjectSpace. Galileo shall not be liable for
          any interest or penalties assessed as a result of any delay by
          ObjectSpace in connection with any such taxes.

     B.   If a claim is made against ObjectSpace for any taxes that are to be
          paid by Galileo, ObjectSpace shall promptly notify Galileo. If Galileo
          so requests in writing, ObjectSpace shall, at Galileo's expense, take
          such action as Galileo may reasonably direct with respect to such
          taxes, including payment of such taxes under protest. If the tax has
          been paid, and if requested by Galileo, ObjectSpace shall, at
          Galileo's expense, take such action as Galileo may reasonably direct,
          including allowing Galileo to file a claim or commence legal action in
          ObjectSpace's name, to recover such tax payment. In the event of
          refund or recovery of any tax, or part thereof, ObjectSpace shall pay
          to Galileo promptly that portion of the tax paid by Galileo, including
          any interest received thereon.

12. INDEMNIFICATION

     ObjectSpace shall defend, indemnify and hold harmless Galileo, its owners,
     officers, employees, and agents (collectively "Galileo"), from and against

     costs and expenses (including reasonable attorneys' fees and expenses)
     resulting from any claim, suit or demand by any third party arising from
     (I) infringement of any intellectual property or other proprietary right of
     any third party arising from any act by the ObjectSpace or Personnel or
     Galileo's exercise of the rights granted hereunder, (ii) injuries to or
     deaths of persons or loss of or damage to tangible property caused by
     ObjectSpace or Personnel; (iii) the negligence or willful misconduct of
     ObjectSpace or Personnel; or iv) breach by ObjectSpace or Personnel of this
     Agreement (including any representation or warranty made hereunder), all
     except to the extent proximately caused by the negligence or intentional
     misconduct of Galileo. ObjectSpace's obligations under this Section 12
     shall survive the expiration or other termination of this Agreement.
     Galileo agrees to provide ObjectSpace with written notice of any such third
     party claim or suit and reasonable cooperation in the defense of any such
     claim or suit. ObjectSpace shall have complete control over the defense and
     settlement of any such claim or suit. In the event of a claim or suit
     covered by Section 12(1) above, ObjectSpace may, at its option, and in
     complete fulfillment of its obligations under this Section 12 either, at
     the sole discretion of ObjectSpace, (a) secure by license or otherwise, the
     right for Galileo to continue to use the allegedly infringing material, (b)
     replace the allegedly infringing material with a non-infringing substitute
     of substantially equivalent functionality or, (c) return any funds received
     from Galileo that are directly related to the delivery of the allegedly
     infringing material, such funds may be associated with one or more Task
     Orders and may comprise all or part of the compensation associated with a
     Task Order.

13. CONSEQUENTIAL DAMAGES AND LIMITATIONS ON DAMAGES


                                                                     Page 5 of 9

          Galileo's business to a third party, or to influence any act or
          decision of any government employee or representative, or of any
          employee or representative of Galileo, to perform or to fail to
          perform his or her duties, or to enlist the aid of any third party to
          do any of the foregoing.

     C.   In connection with any performance under this Agreement, ObjectSpace
          shall not solicit or receive any amount of cash or negotiable paper,
          or any item, service or favor of value from any present or prospective
          supplier, vendor or customer of Galileo, or from anyone else with whom
          Galileo does business, including any governmental official or

                  header files of the type necessary for use or interoperation
                  with other computer programs. It is directly executable by a

         b.       SOURCE CODE is Code in a form which when printed out or
                  displayed is readable and understandable by a programmer of
                  ordinary skills. It includes related source code level system
                  documentation, comments and procedural code. Source Code does
                  not include Object Code.

 1.2     DELIVERABLE is any item that ObjectSpace provides under this Agreement.

 1.3     DERIVATIVE WORK is a work that is based on an underlying work and that
         would be a copyright infringement if prepared without the authorization
         of the copyright owners of the underlying work. Derivative Works are
         subject to the ownership rights and licenses of a party or of others in
         the underlying work.

 1.4     DISTRIBUTORS are those authorized or licensed by Tivoli or IBM, or any
         of their Subsidiaries or Distributors, to license or distribute
         Products.

                  operating systems and devices.
         b.       MAJOR ENHANCEMENTS provide substantial additional value and
                  are offered to customers for an additional charge.

 1.6     ERROR CORRECTIONS are revisions that correct errors and deficiencies
         (collectively referred to as "errors") in the Licensed Works.

 1.7     EXTERNALS are (1) any pictorial, graphic, and audiovisual works (such
         as icons, screens, sounds, and characters) generated by execution of
         Code, and (2) any programming interfaces, languages or protocols
         implemented in Code to enable interaction with other computer programs
         or the end user. Externals do not include the Code that implements
         them.

 1.8     LICENSED WORK is (1) ObjectSpace Voyager Code, in both Object Code and
         Source Code format, including any other material described in or that
         conforms to the description in the Attachment entitled "Description of

         Licensed Work contained in the Product by integrating, embedding,
         bundling or incorporating it into or with one or more of Tivoli's
         network or systems management products or suite of products (including
         IBM if such Tivoli products are transferred to it) such that the

CONFIDENTIAL INFORMATION HAS BEEN OMITTED FROM THIS DOCUMENT AND FILED
SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 406 OF
THE SECURITIES ACT OF 1933, AS AMENDED. ASTERISKS DENOTE THESE OMISSIONS.

                  "Certificate of Originality". Tivoli may suspend payments to
                  ObjectSpace for the Licensed Work if ObjectSpace does not
                  provide a properly completed certificate. Payment will resume
                  after Tivoli receives and accepts the certificate.

2.2      ObjectSpace will provide support for the Licensed Work as follows:

         a.       For the first full year following the Effective Date,
                  ObjectSpace will provide to Tivoli, at no charge, testing,
                  maintenance and support for the Licensed Work as described in
                  this Agreement, including the Attachment entitled, "Testing,
                  Maintenance and Support," as well as Basic and Major
                  Enhancements, and Error Corrections for the Licensed Work
                  beginning when Tivoli accepts the Licensed Work.
         b.       For the second full year following the Effective Date, Tivoli
                  may, at its option, elect to continue to purchase such
                  testing, maintenance, support, Enhancements (both Basic and
                  Major), and Error Corrections from ObjectSpace for an annual
                  fee of *.
         c.       Thereafter, Tivoli may, at its option, elect to continue to
                  purchase such testing, maintenance, support, Enhancements
                  (both Basic and Major), and Error Corrections from ObjectSpace
                  for the annual fee defined in this paragraph for so long as
                  Tivoli may require such support. ObjectSpace may charge Tivoli
                  an annual fee for such support not to exceed 105% of the fee
                  for the prior twelve month period.
         d.       ObjectSpace agrees to submit an invoice to Tivoli for such
                  support on an annual basis, and at least 30 days prior to the
                  beginning of each 12 month period. If Tivoli does not wish to
                  receive such support, Tivoli will so notify ObjectSpace.
         e.       If Tivoli cancels such support, Tivoli may reinstate it at a
                  later time by paying the support charges then in effect and an
                  additional fee. The additional fee will be equal to the
                  current annual support charges multiplied by the number of
                  annual periods for which support was interrupted. For purposes
                  of calculating the additional fee, portions of periods will
                  count as full periods.

2.3      ObjectSpace will:

         a.       participate in progress reviews, as requested by Tivoli, to
                  demonstrate ObjectSpace's performance of ObjectSpace's
                  obligations;
         b.       implement or continue suitable processes designed to help
                  prevent contamination by harmful code. ObjectSpace will
                  provide Tivoli notice if ObjectSpace suspects contamination;
         c.       have agreements with ObjectSpace's personnel and third parties
                  to perform obligations and to grant or assign rights to Tivoli
                  as required by this Agreement. On request, ObjectSpace will
                  provide Tivoli with evidence of these agreements;
         d.       maintain records to verify authorship of the Licensed Work for
                  4 years after the termination or expiration of this Agreement.
                  On request, ObjectSpace will deliver or otherwise make
                  available this information in a form specified by Tivoli;
         e.       not assign or transfer this Agreement or ObjectSpace's rights
                  under it, or delegate or subcontract ObjectSpace's
                  obligations, without Tivoli's prior written consent.
                  Notwithstanding the foregoing, ObjectSpace may assign or
                  otherwise transfer this

                  Agreement, or delegate its duties and obligations under
                  this Agreement, to a Subsidiary of ObjectSpace, without the
                  consent of Tivoli, but ObjectSpace will promptly notify
                  Tivoli of any such transfer, assignment or delegation. Any
                  other attempt to do so is void. In addition, ObjectSpace
                  specifically agrees that, prior to any planned sale by
                  ObjectSpace of the Licensed Work or sale by ObjectSpace of
                  its assets, which include the Licensed Work, including any
                  merger or other business combination, it will offer the
                  Licensed Work to Tivoli under the same terms and
                  conditions, including pricing, as ObjectSpace agreed on
                  with such prospective purchaser, on a first right of
                  refusal basis. If Tivoli elects not to exercise such right,
                  it will not unreasonably withhold its consent to an
                  ObjectSpace request under this section;
         f.       not provide any information to the media, or issue any press
                  releases or other publicity, regarding this Agreement or the
                  parties' relationship under it, without Tivoli's prior written
                  consent, except as otherwise set forth in Section 4.1 of this
                  Agreement; and
         g.       not disclose to a third party the terms of this Agreement or
                  the fact that Tivoli has licensed the Licensed Work, without
                  Tivoli's prior written consent, except as otherwise set forth
                  in Section 4.1 of this Agreement. ObjectSpace may, however,
                  make such disclosures (i) to its accountants, lawyers or other
                  professional advisors provided that any such advisor is under
                  a confidentiality obligation and (ii) as required by law
                  provided ObjectSpace obtains any confidentiality treatment for
                  it which is available.

2.4      If ObjectSpace fails to deliver the Licensed Work, Tivoli may either
         reduce any amounts due hereunder by an amount equal to the value not
         received, or have ObjectSpace reimburse Tivoli for the value not
         received, up to the total license fee set forth under Section 6 below.
         ObjectSpace also acknowledges that if it does not deliver the Licensed
         Work, Tivoli will suffer irreparable harm and will be entitled to all
         equitable remedies, including specific performance for the delivery of
         such Licensed Work.

         If ObjectSpace fails to deliver maintenance, support, Enhancements
         (both Basic and Major), and Error Corrections for a Licensed Work,
         Tivoli may either reduce any amounts due hereunder by an amount equal
         to the value not received, or have ObjectSpace reimburse Tivoli for the
         value not received, up to a total of the annual fee paid by Tivoli for
         the year in which such failure occurred.

3.0      TIVOLI OBLIGATIONS

3.1      Tivoli will provide ObjectSpace with the following Tivoli software
         programs, in the quantities specified, under the terms and conditions
         of its standard Tivoli End User License Agreement, a copy of which is
         attached to this Agreement. In consideration of the rights and licenses
         granted by ObjectSpace under this Agreement, Tivoli agrees to waive the
         one-time charge for such programs, and the first year's fee for
         maintenance and support for the such programs as described in the
         Tivoli End User License Agreement. After the first year, such
         maintenance and support will be available at Tivoli standard pricing.

 4.0     MUTUAL OBLIGATIONS

         commercially practicable following the Effective Date.

 4.2     The parties agree to perform certain joint marketing activities
         regarding Products when such marketing is to the mutual benefit of both
         parties, as determined by each party in its sole discretion.

 4.3     Tivoli agrees to allow ObjectSpace to write a case study covering the
         benefits Tivoli received through the use of the Licensed Work as an
         infrastructure for the development of Products. Tivoli will allow
         ObjectSpace to interview up to five members of its development and
         marketing staff in connection with this case study. Subject to Tivoli's
         final approval and provided no confidential information of Tivoli is
         included, this case study is for unrestricted publication by
         ObjectSpace. Tivoli has full rights to review and approve all contents
         of the case study. ObjectSpace will cooperate with Tivoli in making any
         changes needed to achieve a case study acceptable to Tivoli, and Tivoli
         will cooperate with ObjectSpace to facilitate its internal review and
         approval processes.

5.0      LICENSE GRANTS

5.1      ObjectSpace grants Tivoli a nonexclusive, worldwide, perpetual,
         irrevocable, paid-up license to prepare Derivative Works of, and only
         to internally use, execute, reproduce, display, perform, and
         distribute, the Licensed Work in Source Code form, any Tools (in the
         event ObjectSpace delivers Tools under Section 2.1.b) and such
         Derivative Works, in any medium or distribution technology whatsoever,
         whether known or unknown, solely for Products. The rights and licenses
         granted by ObjectSpace to Tivoli hereunder also include the right of

         Subsidiaries, contractors, and consultants, to exercise any of the

         consultants will be under appropriate confidentiality restrictions no
         less restrictive than the CDA referenced on the first page of this
         Agreement.

 5.2     ObjectSpace also grants Tivoli a nonexclusive, worldwide, perpetual,
         irrevocable, paid-up right to sublicense and deliver a copy of the
         Source Code of the Licensed Work and Derivative Works thereof to third
         parties, including but not limited to Distributors, only in association
         with the


                                       6
<PAGE>


         delivery and sublicensing of the Source Code of Products, and only
         if the Source Code is subject to the same restrictions as the Source
         Code of the Product. This includes the ability to sublicense the
         Source Code of a Product to fulfill an escrow obligation if its
         customer(s) requires Tivoli or IBM to place Source Code in an escrow
         account for maintenance and support purposes. The rights and
         licenses granted by ObjectSpace to Tivoli hereunder also include the
         right of Tivoli to authorize or sublicense IBM, and any of Tivoli's
         and IBM's Subsidiaries, to exercise any of the rights granted to
         Tivoli in this Section 5.2.

 5.3     ObjectSpace grants Tivoli a nonexclusive, worldwide, perpetual,
         irrevocable, paid-up license to reproduce, transfer, distribute
         internally and externally, and sublicense the Object Code only of the
         Licensed Work and its Derivative Works, and documentation, in any
         medium or distribution technology whatsoever, whether known or unknown,
         provided that such Object Code is distributed and sublicensed in
         conjunction with Products, and not in a stand-alone form. ObjectSpace
         grants Tivoli the right to authorize or sublicense others to exercise
         any of the rights granted to Tivoli in this Section 5.3.

 5.4     ObjectSpace grants Tivoli a nonexclusive, worldwide, perpetual,
         irrevocable, paid-up license to prepare Derivative Works of the
         Externals, and to use, execute, reproduce, display, perform, transfer,
         distribute, and sublicense the Externals and such Derivative Works, in
         any medium or distribution technology whatsoever, whether known or
         unknown. ObjectSpace grants Tivoli the right to authorize or sublicense
         others to exercise any of the rights granted to Tivoli in this Section
         5.4.

 5.5     The grant of rights and licenses to the Licensed Work and Tools
         includes a nonexclusive, worldwide, perpetual, irrevocable, paid-up
         license under any patents and patent applications that are owned or
         licensable by ObjectSpace now or in the future and are (1) required to
         make, have made, use and have used the Licensed Work or its Derivative
         Works or (2) required to license or transfer the Licensed Work or its
         Derivative Works; provided, however, that-a license to such patents
         would have been required to exercise these rights to the Licensed Work
         without regard to the Derivative Works. This license applies to the
         Licensed Work and its Derivative Works operating alone or in
         combination with equipment or Code. The license scope is to make, have
         made, use, have used, sell, license or transfer items, and to practice
         and have practiced methods, to the extent required to exercise the
         rights granted hereunder to the Licensed Work and Tools.

 5.6     Subject to ObjectSpace's ownership of the Licensed Work and Tools,
         Tivoli will own any Derivative Works it creates.

 5.7     ObjectSpace grants Tivoli a nonexclusive, worldwide, perpetual,
         irrevocable, paid-up license to use the names and trademarks
         ObjectSpace uses to identify the Licensed Work for Tivoli's marketing
         of the Products. ObjectSpace grants Tivoli the right to authorize or
         sublicense others to exercise any of the rights granted to Tivoli in
         this Section 5.7. If Tivoli's use of ObjectSpace's names and trademarks
         is improper and ObjectSpace provides Tivoli notice that ObjectSpace
         objects to it, Tivoli will take all reasonable steps necessary to
         resolve ObjectSpace's objections. ObjectSpace may reasonably monitor
         the quality of products bearing its trademark under this license.

 5.8     Any goodwill attaching to Tivoli's trademarks, service marks, or trade
         names belongs to Tivoli and this Agreement does not grant ObjectSpace
         any right to use them. Tivoli may state that ObjectSpace has provided
         the Licensed Work. ObjectSpace may state that it has licensed the
         Licensed Work to Tivoli.

 5.9     Subject to agreement on the license fee to be paid to ObjectSpace,
         ObjectSpace agrees that the rights and licenses granted by ObjectSpace
         hereunder also include the right of Tivoli and IBM to exercise any of
         the rights granted to Tivoli in this Section 5 on products other than
         the Product.

         ObjectSpace further agrees that any such license fee will be
         reasonable, nondiscriminatory, and consistent with the license fee paid
         by other similarly situated customers.

 6.0     PAYMENT

 6.1     For the rights and licenses received, Tivoli will pay ObjectSpace a
         total license fee of * in two payments, as follows:

 6.2     ObjectSpace will submit invoices to Tivoli for the above amounts prior

         will pay ObjectSpace the amounts due upon the above dates.

 6.3.    For support as set forth in Section 2.2, ObjectSpace agrees to submit
         an invoice to Tivoli for such support on an annual basis, and at least
         30 days prior to the beginning of each 12 month period. After Tivoli's
         receipt of a valid invoice, Tivoli will pay ObjectSpace the amounts due
         within 30 days. If Tivoli does not wish to receive such support, Tivoli
         will so notify ObjectSpace.

 6.4     All invoices will include the following information:

         a. ObjectSpace's company and remit to address; and
         b. Reference to this Agreement by its number and its date.

 6.5     All invoices will be addressed to the designated Contract Coordinator
         at Tivoli Systems, Inc. and sent (with a copy to the Tivoli Technical
         Coordinator) to the following address:

<PAGE>


 6.7     The payments defined in this Section fully compensate ObjectSpace for
         its performance under, and for the rights and licenses granted in, this
         Agreement.

 7.0     TESTING

 7.1     ObjectSpace will perform the following tests prior to each delivery of
         the Licensed Work:

         a.   component testing;
         b.   functional verification testing; and
         c.   compatibility testing.

         Upon Tivoli's request, the details of such testing will be mutually
         agreed to by the parties.

 7.2     ObjectSpace will provide to Tivoli concurrent with each delivery of the
         Licensed Work and Tools all test results, test scenarios, test cases,
         and test reports associated with the pre-delivery testing.

 7.3     Upon receipt of the Licensed Work by Tivoli, Tivoli may evaluate the
         Licensed Work for a period of 30 days and perform such tests as Tivoli
         deems appropriate to determine whether:

         a.       the Licensed Work meets the specifications described in the
                  Attachment entitled "Description of Licensed Work";
         b.       the Licensed Work executes repetitively within the system
                  environment described in the Attachment entitled "Description
                  of Licensed Work"; and
         c.       Tivoli can successfully execute to completion all functional
                  and system test scenarios developed by Tivoli.

         Tivoli's testing does not relieve ObjectSpace of its obligations under
         this Agreement. Tivoli has no obligation to identify errors.

 8.0     REPRESENTATIONS AND WARRANTIES

 8.1     ObjectSpace makes the following ongoing representations and warranties:

         a.       ObjectSpace has full legal rights to grant the rights granted

                  products (for example, hardware, software and firmware) with
                  which the Licensed Work is designed to be used; and
         i.       neither the Licensed Work nor the Tools are contaminated by

         change that may affect its representations and warranties.

 8.2     Except as provided above, anything either party provides to the other
         related to this Agreement is "AS IS", without warranty of any kind.

 9.0     INDEMNIFICATION AND LIABILITY

 9.1     BY OBJECTSPACE. ObjectSpace will be responsible for and will indemnify
         Tivoli, IBM, and any of their Subsidiaries, from any and all damages,
         settlements, costs, expenses and liabilities of any type whatsoever, if
         a third party makes a claim against Tivoli, IBM, or any of their
         Subsidiaries based on an actual or alleged:

         a.       failure by ObjectSpace, to the extent not caused by Tivoli, to
                  perform ObjectSpace's obligations under this Agreement;
         b.       breach of ObjectSpace's representations and warranties;
         c.       assertion or claim that a person or entity other than
                  ObjectSpace has Moral Rights in the Licensed Work;
         d.       failure by ObjectSpace to comply with government laws and
                  regulations; or
         e.       infringement by ObjectSpace, the Licensed Work or Tools of
                  patents, copyrights, trademarks, trade secrets, and other
                  intellectual property rights, except to the extent such a
                  claim is based solely on the combination, operation or use of
                  the Licensed Work with programs or data not supplied by
                  ObjectSpace, if such infringement would have been avoided but
                  for the combination, operation or use of the Licensed Work
                  with such other programs or data.

         Tivoli will:

         a.       promptly provide ObjectSpace notice of any such claim; and
         b.       allow ObjectSpace to control, and cooperate with ObjectSpace
                  in the defense of, the claim and settlement negotiations.

                  Subsidiaries and Distributors, and their respective customers
                  to continue to distribute, license, otherwise transfer and use

         If ObjectSpace is not able to do either within a reasonable period of
         time, Tivoli may terminate this Agreement for ObjectSpace's breach.

         9.1 is limited to *.

 9.2     BY TIVOLI. If a claim is made against ObjectSpace by a third party
         based upon the distribution of Products provided for under this
         Agreement, Tivoli will be responsible for and will indemnify
         ObjectSpace from any and all damages, settlements, costs, expenses and
         liabilities of any type whatsoever regarding such third party claim,
         with the exception of those activities for which ObjectSpace bears
         responsibility under Section 9.1 of this Agreement, and provided
         ObjectSpace gives Tivoli prompt written notice of any such claim,
         together with the full authority for and cooperation with such a
         defense and any settlement negotiations.

         Tivoli's total liability for indemnification under this Section 9.2 is
         limited to *.

 9.3     In addition to any remedies specified in this Agreement, either party
         may pursue any other remedy it may have in law or in equity. Regardless
         of the type of claim, neither party is liable to the other for
         indirect, incidental, special, or consequential damages including, but
         not limited to, lost profits or revenues, under any part of this
         Agreement, even if informed that they may occur. This limitation does
         not apply to (a) ObjectSpace's liabilities for indemnity above, or (b)
         Tivoli's liabilities for indemnity above. Other than with respect to
         Tivoli's liability for indemnity above, Tivoli's total liability is
         limited to payments due to ObjectSpace under this Agreement; provided,
         however, that Tivoli's total liability with respect to a violation of
         the license grant set forth in Sections 5.1 or 5.3 is limited to *.

 10.0    TERM AND TERMINATION

 10.1    This Agreement begins on the Effective Date and has a term of one year
         unless terminated sooner under the terms of this Agreement; provided,
         however, that this Agreement will be extended automatically for
         additional one year periods upon the anniversary of the Effective Date.

 10.2    Either party may terminate this Agreement for the other's material
         breach by providing the breaching party with a written notice that
         describes the breach. The termination will become effective 45 days
         after receipt of the notice unless the breach is cured within that 45
         day period. However, if the breach (other than a breach for failure to
         deliver the Licensed Work) by its nature, cannot be remedied in 45
         days, but can be remedied in a reasonable time thereafter, the


                                       11
<PAGE>


         breaching party will take reasonable and diligent steps to remedy it,
         notify the other party of the action plan, progress towards completion,
         and complete such remedial action promptly. In such event, the notice
         period will be suspended while the breaching party takes these actions.

 10.3    Tivoli may, for its convenience, terminate this Agreement on 30 days'
         written notice to ObjectSpace. After the Agreement has been in effect
         for 4 years from the Effective Date, ObjectSpace may, for its
         convenience, terminate this Agreement on twelve months' written notice
         to Tivoli.

 10.4    Expiration of this Agreement does not affect any licenses granted in
         this Agreement for the Licensed Work or Tools. Termination of this
         Agreement does not affect any licenses granted in this Agreement for
         the Licensed Work or Tools delivered or due to Tivoli prior to the
         effective date of termination.

 10.5    Subject to Subsection 10.4, any provisions of this Agreement that by
         their nature extend beyond termination or expiration will survive in
         accordance with their terms. These include Section 5, "LICENSE GRANTS,"
         Section 8.0, "REPRESENTATIONS AND WARRANTIES," Section 9.0,
         "INDEMNIFICATION AND LIABILITY," and Section 12, "GENERAL." These terms
         will apply to either party's successors and assigns.

         Technical Coordinators may propose, accept (by signature or initial),
         and implement technical changes to this Agreement that do not change
         dollar amounts or materially change Deliverables or the schedules of
         this Agreement.

11.4     A party will provide written notice to the other when its coordinators
         change.

12.0     GENERAL

12.1     INDEPENDENT CONTRACTOR. Each party is an independent contractor.
         Neither party is, nor will claim to be, a legal representative,
         partner, franchisee, agent or employee of the other except as
         specifically stated in the Subsection entitled "Copyright" below.
         Neither party will assume or create obligations for the other. Each
         party is responsible for the direction and compensation of its
         employees.

12.2     FREEDOM OF ACTION. Each party may have similar agreements with others.
         Each party may design, develop, manufacture, acquire or market
         competitive products and services, and conduct its business in whatever
         way it chooses. Tivoli is not obligated to announce or market any
         products or services. Tivoli does not guarantee the success of its
         marketing efforts. Tivoli will independently establish prices for its
         products and services.

12.3     RELIANCE. Neither party relies on any promises, inducements or
         representations made by the other or expectations of more business
         dealings, except as expressly provided in this Agreement. This
         Agreement accurately states the parties' agreement.

12.4     COMPLIANCE WITH APPLICABLE LAWS. Each party will comply with all
         applicable laws and regulations at its expense including, to the extent
         applicable, Executive Order 11246 on Equal Employment Opportunity, as
         amended, the Occupational Safety and Health Act of 1970, as amended,
         and the Americans With Disabilities Act of 1990, as amended. This also
         includes all applicable government export and import laws and
         regulations.

12.5     CONFIDENTIAL INFORMATION. The parties agree that information exchanged
         under this Agreement that is considered by either party to be
         confidential information will be subject to the terms of the CDA
         referenced on the first page of this Agreement and its Supplements. In
         addition, ObjectSpace will not provide Tivoli with any information
         which may be considered confidential information of any third party
         unless provided under the CDA. The obligations set forth in the CDA
         with regard to confidential information will not limit or preclude the
         exercise of the licenses granted in this Agreement.

12.6     COPYRIGHT. Any publication by Tivoli of the Licensed Works or a
         Derivative Work thereof will contain an appropriate copyright notice,
         as determined by Tivoli. Tivoli will retain any copyright notices
         ObjectSpace has on the Licensed Work.


                                       13
<PAGE>


         ObjectSpace will enforce and maintain its copyright protection in the
         Licensed Works. Tivoli is not responsible for enforcing and maintaining
         such copyright protection. However, ObjectSpace authorizes Tivoli to
         act as ObjectSpace's agent in the copyright registration of the
         Licensed Works. At Tivoli's request, ObjectSpace agrees to provide
         Tivoli reasonable assistance in registering any Product.

12.7     ORDER OF PRECEDENCE. If there is a conflict among the terms of this
         base License Agreement and its Attachments, the terms of this base
         License Agreement prevail over those of the Attachments, unless the
         parties expressly indicate in the Attachments that particular terms
         within the Attachments prevail. Terms in Tivoli's purchase orders and
         ObjectSpace's invoices are void.

12.8     HEADINGS. The headings of this Agreement are for reference only. They
         will not affect the meaning or interpretation of this Agreement.

12.9     COUNTERPARTS. This Agreement may be signed in one or more counterparts,
         each of which will be considered an original, but all of which together
         form one and the same instrument.

12.10    AMENDMENT AND WAIVERS. For a change to this Agreement to be valid, both
         parties must sign it. No approval, consent or waiver will be
         enforceable unless signed by the granting party. Failure to insist on
         strict performance or to exercise a right when entitled does not
         prevent a party from doing so later for that breach or a future one.

12.11    ACTIONS. Neither party will bring a legal action relating to the
         subject matter of this Agreement, against the other more than 2 years
         after the cause of action arose, except in the case of indemnification
         for infringement, in which case this period runs for 2 years after the
         award or settlement was made.

12.12    DISPUTE RESOLUTION. Both parties will act in good faith to resolve
         disputes prior to instituting litigation. Each party waives its rights
         to a jury trial in any resulting litigation.

12.13    GOVERNING LAW. This Agreement will be governed by the substantive law
         of the State of Texas applicable to contracts executed in and performed
         entirely within that State, without regard to choice of law principles,
         regulations, or statutes of this or any other jurisdiction. The United
         Nations Convention on Contracts for the International Sale of Goods
         does not apply. ObjectSpace will, upon written notice from Tivoli,
         submit to personal jurisdiction in any forum where Tivoli is sued for
         claims related to this Agreement.

         2.       LOAN AND TERMS OF PAYMENT

                  2.1  CREDIT EXTENSIONS. Borrower promises to pay to the
order of Bank, in lawful money of the United States of America, the aggregate
unpaid principal amount of all Credit Extensions made by Bank to Borrower
hereunder. Borrower also promises to pay interest on the unpaid principal
amount of such Advances at rates in accordance with the terms hereof.

                           2.1.1 (a) Subject to and upon the terms and
conditions of this Agreement, Bank agrees to make Advances to Borrower in an
aggregate outstanding amount not to exceed (i) the Committed Revolving Line or
the Borrowing Base, whichever is less, minus (ii) the face amount of all
outstanding Letters of Credit (including drawn but unreimbursed Letters of
Credit) and any Letter of Credit Reserve. Subject to the terms and conditions of
this Agreement, amounts borrowed pursuant to this Section 2.1 may be repaid and
reborrowed at any time during the term of this Agreement.

                                 (b) Whenever Borrower desires an Advance,
Borrower will notify Bank by facsimile transmission or telephone no later than
3:00 p.m. Pacific time, on the Business Day that the Advance is to be made. Each
such notification shall be promptly confirmed by a Payment/Advance Form in
substantially the form of EXHIBIT B hereto. Bank is authorized to make Advances
under this Agreement, based upon instructions received from a Responsible
Officer or a designee of a Responsible Officer, or without instructions if in
Bank's discretion such Advances are necessary to meet Obligations which have
become due and remain unpaid. Bank shall be entitled to rely on any telephonic
notice given by a person who Bank reasonably believes to be a Responsible
Officer or a designee thereof, and Borrower shall indemnify and hold Bank
harmless for any damages or loss suffered by Bank as a result of such reliance.
Bank will credit the amount of Advances made under this Section 2.1 to
Borrower's deposit account.

                                 (c) The Committed Revolving Line shall
terminate on the Revolving Maturity Date, at which time all Advances under
this Section 2.1 and other amounts due under this Agreement (except as
otherwise expressly specified herein) shall be immediately due and payable.
Notwithstanding the foregoing, Bank's commitment to make any Overadvance
shall terminate on the Overadvance Maturity Date at which time all
outstanding Overadvance principal plus all accrued interest not yet paid
shall be immediately due and payable.

                           2.1.2    LETTERS OF CREDIT.

                                    (a) Subject to the terms and conditions of
this Agreement, Bank agrees to issue or cause to be issued Letters of Credit for
the account of Borrower in an aggregate outstanding face amount not to exceed
(i) the lesser of the Committed Revolving Line or the Borrowing Base minus (ii)
the then outstanding principal balance of the Credit Extensions; PROVIDED that
the face amount of outstanding Letters of Credit (including drawn but
unreimbursed Letters of Credit and any Letter of Credit Reserve) shall not in
any case exceed One Million Five Hundred Thousand and No/100 Dollars
($1,500,000.00). Each Letter of Credit shall have an expiry date no later than
one hundred eighty (180) days after the Revolving Maturity Date provided that
Borrower's Letter of Credit reimbursement obligation shall be secured by cash on
terms acceptable to Bank at any time after the Revolving Maturity Date if the
term of this Agreement is not extended by Bank. All Letters of Credit shall be,
in form and substance, acceptable to Bank in its sole discretion and shall be
subject to the terms and conditions of Bank's form of standard Application and
Letter of Credit Agreement; provided, that Bank shall not charge any fee in
connection with (x) its reissuance of the three Letters of Credit in the
aggregate face amount of One Million Eighty-Six Thousand Six Hundred Six and
68/100 Dollars ($1,086,606.68), replacing those three Letters of Credit
currently issued for the account of Borrower by a third Person or (y) its
issuance of a Letter of Credit for the account of Borrower in the amount of One
Hundred Fifty-Six Thousand Five Hundred Forty-Five Dollars and No/100 Dollars
($156,545.00).

                                    (b) The obligation of Borrower to
immediately reimburse Bank for drawings made under Letters of Credit shall be
absolute, unconditional and irrevocable, and shall be performed strictly in
accordance with the terms of this Agreement and such Letters of Credit, under
all circumstances whatsoever. BORROWER SHALL INDEMNIFY, DEFEND, PROTECT, AND
HOLD BANK HARMLESS FROM ANY AND ALL LOSS, COST, EXPENSE OR LIABILITY, INCLUDING,
WITHOUT LIMITATION, REASONABLE ATTORNEYS' FEES, ARISING OUT OF OR IN CONNECTION
WITH ANY LETTERS OF CREDIT.

                                    (c) Borrower may request that Bank issue a
Letter of Credit payable in a currency other than United States Dollars. If a
demand for payment is made under any such Letter of Credit, Bank shall treat
such demand as an Advance to Borrower of the equivalent of the amount thereof
(plus cable charges) in United States currency at the then prevailing rate of
exchange in Austin, Texas for sales of that other currency for cable transfer to
the country of which it is the currency.

                                    (d) Upon the issuance of any letter of
credit payable in a currency other than United States Dollars, Bank shall create
a reserve under the Committed Revolving Line for letters of credit against
fluctuations in currency exchange rates, in an amount equal to ten percent (10%)
of the face amount of such letter of credit ("Letter of Credit Reserve"). The
amount of such reserve may be amended by Bank from time to time to account for
fluctuations in the exchange rate.


                                      11
<PAGE>


The availability of funds under the Committed Revolving Line shall be reduced
by the amount of such reserve for so long as such letter of credit remains
outstanding.

                  2.2  EXCESS ADVANCES. If, at any time or for any reason,
the amount of Obligations owed by Borrower to Bank pursuant to Section 2.1.1
and 2.1.2 of this Agreement is greater than the lesser of (i) the Committed
Revolving Line or (ii) the Borrowing Base, Borrower shall immediately pay to
Bank, in cash, the amount of such excess.

                  2.3  INTEREST RATES, PAYMENTS, AND CALCULATIONS.

                       (a) INTEREST RATE. Except as set forth in Section
2.3(b), all Advances, other than Overadvances, shall bear interest, on the
average daily balance thereof, at a per annum rate equal to seventy-five
percentage points (0.75%) above the Prime Rate. Except as set forth in
Section 2.3(b), all Overadvances shall bear interest, on the average daily
balance thereof, at a per annum rate equal to one and one-half percent
percentage points (1.5%) above the Prime Rate.

                       (b) DEFAULT RATE. All Obligations shall bear interest,
from and after the occurrence of an Event of Default, at the "Default
Interest Rate". The Default Interest Rate shall be, at Bank's option, (i) the
Maximum Lawful Rate, if such Maximum Lawful Rate is established by applicable
law; or (ii) the interest rate applicable immediately prior to the occurrence
of the Event of Default plus five (5) percentage points, if no Maximum Lawful
Rate is established by applicable law; or (iii) eighteen percent (18%) per
annum; or (iv) such lesser rate of interest as Bank in its sole discretion
may choose to charge; but never more than the Maximum Lawful Rate or at a
rate that would cause the total interest contracted for, charged or received
by Bank to exceed the Maximum Lawful Amount.

                       (c) PAYMENTS. Interest hereunder shall be due and
payable on each Payment Date. Any interest not paid when due shall be
compounded by becoming a part of the Obligations, and such interest shall
thereafter accrue interest at the rate then applicable hereunder.

                       (d) COMPUTATION.

                           (i) CHANGES. In the event the Prime Rate is
changed from time to time hereafter, the applicable rate of interest
hereunder shall be increased or decreased effective as of 12:01 a.m. on the
day the Prime Rate is changed, by an amount equal to such change in the Prime
Rate.

                           (ii) SPREADING OF INTEREST. Because of the
possibility of irregular periodic balances of principal, the fluctuating
nature of the interest rate, or premature payment, the total interest that
will accrue under this Agreement cannot be determined in advance. Bank does
not intend to contract for, charge or receive more than the Maximum Lawful
Rate or Maximum Lawful Amount permitted by applicable state or federal law,
and to prevent such an occurrence Bank and Borrower agree that


                                      12
<PAGE>


all amounts of interest, whenever contracted for, charged or received by
Bank, with respect to the loan of money evidenced by the Loan Documents,
shall be spread, prorated or allocated over the full period of time the
Obligations are unpaid, including the period of any renewal or extension
thereof. If the maturity of the Obligations is accelerated for any reason
whether as a lawsuit or an Event of Default or otherwise prior to the full
stated term, the total amount of interest contracted for, charged or received
to the time of such demand shall be spread, prorated or allocated along with
any interest thereafter accruing over the full period of time that the
Obligations thereafter remain unpaid for the purpose of determining if such
interest exceeds the Maximum Lawful Amount.

                           (iii) EXCESS INTEREST. At maturity (whether by
acceleration or otherwise) or on earlier final payment of the Obligations,
Bank shall compute the total amount of interest that has been contracted for,
charged or received by Bank or payable by Borrower hereunder and compare such
amount to the Maximum Lawful Amount that could have been contracted for,
charged or received by Bank. If such computation reflects that the total
amount of interest that has been contracted for, charged or received by Bank
or payable by Borrower exceeds the Maximum Lawful Amount, then Bank shall
apply such excess to the reduction of the principal balance and not to the
payment of interest; or if such excess interest exceeds the unpaid principal
balance, such excess shall be refunded to Borrower. This provision concerning
the crediting or refund of excess interest shall control and take precedence
over all other agreements between Borrower and Bank so that under no
circumstances shall the total interest contracted for, charged or received by
Bank exceed the Maximum Lawful Amount.

                           (iv) DAILY COMPUTATION OF INTEREST. To the extent
permitted by applicable law, Bank at its option may either (i) calculate the
per diem interest rate or amount based on the actual number of days in the
year (365 or 366, as the case may be), and charge that per diem interest rate
or amount each day, or (ii) calculate the per diem interest rate or amount as
if each year has only 360 days, and charge that per diem interest rate or
amount each day for the actual number of days of the year (365 or 366 as the
case may be). If the Loan Documents call for monthly payments, Bank at its
option may determine the payment amount based on the assumption that each
year has only 360 days and each month has 30 days. In no event shall Bank
compute the interest in a manner that would cause Bank to contract for,
charge or receive interest that would exceed the Maximum Lawful Rate or the
Maximum Lawful Amount.

                           (v) REVOLVING LOAN ACCOUNTS AND USURY CEILING. In
no event shall Chapter 346 of the Texas Finance Code, as supplemented by the
Texas Credit Title ("Texas Finance Code")(which regulates certain revolving
loan accounts and revolving tri-party accounts) apply to this Agreement or
Borrower's payment obligations hereunder. To the extent that Chapter 303 of
the Texas Finance Code, is applicable to this Agreement, the "weekly ceiling"
specified in such Chapter 303 is the


                                      13
<PAGE>


applicable ceiling; provided that, if any applicable law permits greater
interest, the law permitting the greatest interest shall apply.

                  2.4  CREDITING PAYMENTS. Prior to the occurrence of an
Event of Default, Bank shall credit a wire transfer of funds, check or other
item of payment to such deposit account or Obligation as Borrower specifies.
After the occurrence of an Event of Default, the receipt by Bank of any wire
transfer of funds, check, or other item of payment, whether directed to
Borrower's deposit account with Bank or to the Obligations or otherwise,
shall be immediately applied to conditionally reduce Obligations, but shall
not be considered a payment in respect of the Obligations unless such payment
is of immediately available federal funds or unless and until such check or
other item of payment is honored when presented for payment. Notwithstanding
anything to the contrary contained herein, any wire transfer or payment
received by Bank after 12:00 noon Pacific time shall be deemed to have been
received by Bank as of the opening of business on the immediately following
Business Day. Whenever any payment to Bank under the Loan Documents would
otherwise be due (except by reason of acceleration) on a date that is not a
Business Day, such payment shall instead be due on the next Business Day, and
additional fees or interest, as the case may be, shall accrue and be payable
for the period of such extension.

                  2.5  FEES.  Borrower shall pay to Bank the following:

                       (a) FACILITY FEE. A Facility Fee equal to Twenty-Two
Thousand Five Hundred and No/100 Dollars ($22,500.00), which fee shall be due
on the Closing Date and shall be fully earned and non-refundable;

                       (b) FINANCIAL EXAMINATION AND APPRAISAL FEES. Bank's
customary fees and out-of-pocket expenses for Bank's audits of Borrower's
Accounts, and for each appraisal of Collateral and financial analysis and
examination of Borrower performed from time to time by Bank or its agents;

                       (c) BANK EXPENSES. Upon demand from Bank, including,
without limitation, upon the date hereof, all Bank Expenses incurred through
the date hereof, including reasonable attorneys' fees and expenses, and,
after the date hereof, all Bank Expenses, including reasonable attorneys'
fees and expenses, as and when they become due.

                  2.6  ADDITIONAL COSTS. In case any law, after the date
hereof, any regulation, treaty or official directive or the interpretation or
application thereof by any court or any governmental authority charged with
the administration thereof or the compliance with any guideline or request of
any central bank or other governmental authority (whether or not having the
force of law):

                       (a) subjects Bank to any tax with respect to payments
of principal or interest or any other amounts payable hereunder by Borrower

         4.  CREATION OF SECURITY INTEREST

             4.1  GRANT OF SECURITY INTEREST. Borrower grants and pledges to
Bank a continuing security interest in all presently existing and hereafter
acquired or arising Collateral and all proceeds thereof, in order to secure
prompt payment of any and all Obligations and in order to secure prompt
performance by Borrower of each of its covenants and duties under the Loan
Documents. Except as set forth in the Schedule, such security interest
constitutes a valid, first priority security interest in the presently
existing Collateral, and will constitute a valid, first priority security
interest in Collateral acquired after the date hereof. Borrower acknowledges
that Bank may place a "hold" on any deposit account pledged as Collateral to
secure the Obligations. Notwithstanding termination of this Agreement, Bank's
Lien on the Collateral shall remain in effect for so long as any Obligations
are outstanding.

             4.2  DELIVERY OF ADDITIONAL DOCUMENTATION REQUIRED. Borrower
shall from time to time execute and deliver to Bank, at the request of Bank,
all Negotiable

<PAGE>


Collateral, all financing statements and other documents that Bank may
reasonably request, in form satisfactory to Bank, to perfect and continue
perfected Bank's security interest in the Collateral and in order to fully
consummate all of the transactions contemplated under the Loan Documents.

             4.3  RIGHT TO INSPECT. Bank (through any of its officers,
employees, or agents) shall have the right, upon reasonable prior notice,
from time to time during Borrower's usual business hours, to inspect
Borrower's Books and to make copies thereof and to check, test, and appraise
the Collateral in order to verify Borrower's financial condition or the
amount, condition of, or any other matter relating to, the Collateral.

         5.  REPRESENTATIONS AND WARRANTIES

             Borrower represents and warrants as follows:

             5.1  DUE ORGANIZATION AND QUALIFICATION. Borrower and each
Subsidiary is a corporation duly existing and in good standing under the laws
of its state of incorporation and qualified and licensed to do business in,
and is in good standing in Texas, and in any other state in which the conduct
of its business or its ownership of property requires that it be so qualified.

             5.2  DUE AUTHORIZATION; NO CONFLICT. The execution, delivery,
and performance of the Loan Documents are within Borrower's powers, have been
duly authorized, and are not in conflict with nor constitute a breach of any
provision contained in Borrower's Articles of Incorporation or Bylaws, nor
will they constitute an event of default under any material agreement to
which Borrower is a party or by which Borrower is bound. Borrower is not in
default under any agreement to which it is a party or by which it is bound,
which default could have a Material Adverse Effect.

             5.3  NO PRIOR ENCUMBRANCES. Borrower has good and indefeasible
title to the Collateral, free and clear of Liens, except for Permitted Liens.

             5.4  BONA FIDE ELIGIBLE ACCOUNTS. The Eligible Accounts are bona
fide existing obligations. The service or property giving rise to such
Eligible Accounts has been performed or delivered to the account debtor or to
the account debtor's agent for immediate shipment to and unconditional
acceptance by the account debtor. Borrower has not received notice of actual
or imminent Insolvency Proceeding of any account debtor whose accounts are
included in any Borrowing Base Certificate as an Eligible Account.

             5.5  MERCHANTABLE INVENTORY. All Inventory is in all material
respects of good and marketable quality, free from all material defects.

             5.6  INTELLECTUAL PROPERTY. Borrower is the owner of the
Patents, Trademarks, Copyrights and Mask Works subject to licenses granted by
Borrower to


                                      17
<PAGE>

its customers in the ordinary course of business. To Borrower's knowledge,
each of the Patents is valid and enforceable, and no part of the Intellectual
Property Collateral has been judged invalid or unenforceable, in whole or in
part, and no claim has been made that any part of the Intellectual Property
Collateral violates the rights of any third party. Except for and upon the
filing with the United States Patent and Trademark Office with respect to the
Patents and Trademarks and the Register of Copyrights with respect to the
Copyrights and Mask Works necessary to perfect the security interests created
hereunder, and except as has been already made or obtained, no authorization,
approval or other action by, and no notice to or filing with, any United
States governmental authority or United States regulatory body is required
either (i) for the grant by Borrower of the security interest granted hereby
or for the execution, delivery or performance of Loan Documents by Borrower in
the United States or (ii) for the perfection in the United States or the
exercise by Bank of its rights and remedies hereunder.

                  5.7 NAME; LOCATION OF CHIEF EXECUTIVE OFFICE. Except as
disclosed in the Schedule, Borrower has not done business and will not without
at least thirty (30) days prior written notice to Bank do business under any
name other than that specified on the signature page hereof. The chief
executive office of Borrower is located at the address indicated in Section 10
hereof.

                  5.8  LITIGATION. Except as set forth in the Schedule, there
are no actions or proceedings pending, or, to Borrower's knowledge, threatened
by or against Borrower or any Subsidiary before any court or administrative
agency in which an adverse decision could have a Material Adverse Effect on
Borrower's interest or Bank's security interest in the Collateral.

                  5.9  NO MATERIAL ADVERSE CHANGE IN FINANCIAL STATEMENTS. All
consolidated financial statements related to Borrower and any Subsidiary that
have been delivered by Borrower to Bank fairly present in all material
respects Borrower's consolidated financial condition as of the date thereof
and Borrower's consolidated results of operations for the period then ended.
There has not been a material adverse change in the consolidated financial
condition of Borrower since the date of the most recent of such financial
statements submitted to Bank on or about the Closing Date.

                  5.10 SOLVENCY. The fair saleable value of Borrower's assets
(including goodwill minus disposition costs) exceeds the fair value of its
liabilities; the Borrower is not left with unreasonably small capital after
the transactions contemplated by this Agreement; and Borrower is able to pay
its debts (including trade debts) as they mature.

                  5.11 REGULATORY COMPLIANCE. Borrower and each Subsidiary has
met the minimum funding requirements of ERISA with respect to any employee
benefit plans subject to ERISA. No event has occurred resulting from
Borrower's failure to comply with ERISA that is reasonably likely to result in
Borrower's incurring any liability that could have a Material Adverse Effect.

company" or a company "controlled" by an "investment company" within the
meaning of the Investment Company Act of 1940. Borrower is not engaged
principally, or as one of its important activities, in the business of
extending credit for the purpose of purchasing or carrying margin stock
(within the meaning of Regulations G, T and U of the Board of Governors of the
Federal Reserve System). Borrower has complied with all the provisions of the
Federal Fair Labor Standards Act. Borrower has not violated any statutes,
laws, ordinances or rules applicable to it, violation of which could have a
Material Adverse Effect.

                  5.12 ENVIRONMENTAL CONDITION. None of Borrower's or any
Subsidiary's properties or assets has ever been used by Borrower or any
Subsidiary or, to the best of Borrower's knowledge, by previous owners or
operators, in the disposal of, or to produce, store, handle, treat, release,
or transport, any hazardous waste or hazardous substance other than in
accordance with applicable law; to the best of Borrower's knowledge, none of
Borrower's properties or assets has ever been designated or identified in any
manner pursuant to any environmental protection statute as a hazardous waste
or hazardous substance disposal site, or a candidate for closure pursuant to
any environmental protection statute; no lien arising under any environmental
protection statute has attached to any revenues or to any real or personal
property owned by Borrower or any Subsidiary; and neither Borrower nor any
Subsidiary has received a summons, citation, notice, or directive from the
Environmental Protection Agency or any other federal, state or other
governmental agency concerning any action or omission by Borrower or any
Subsidiary resulting in the release, or other disposition of hazardous waste
or hazardous substances into the environment.

                  5.13 TAXES. Borrower and each Subsidiary has filed or caused
to be filed all tax returns required to be filed on a timely basis, and has
paid, or has made adequate provision for the payment of, all taxes reflected
therein.

                  5.14 SUBSIDIARIES. Borrower does not own any stock,
partnership interest or other equity securities of any Person, except for
Permitted Investments.

                  5.15 GOVERNMENT CONSENTS. Borrower and each Subsidiary has
obtained all consents, approvals and authorizations of, made all declarations
or filings with, and given all notices to, all governmental authorities that
are necessary for the continued operation of Borrower's business as currently
conducted.

                  5.16 FULL DISCLOSURE. No representation, warranty or other
statement made by Borrower in any certificate or written statement furnished
to Bank contains any untrue statement of a material fact or omits to state a
material fact necessary in order to make the statements contained in such
certificates or statements not misleading.

                                      23

<PAGE>

                  7.2  CHANGES IN BUSINESS, OWNERSHIP, MANAGEMENT OR BUSINESS
LOCATIONS. Engage in any business, or permit any of its Subsidiaries to engage
in any business, other than the businesses currently engaged in by Borrower

                  7.6  DISTRIBUTIONS. Pay any dividends or make any other
distribution or payment on account of or in redemption, retirement or purchase

defined in that certain Stock Purchase Agreement ("Stock Purchase Agreement")
dated August 21, 1996 between David Cook and Borrower) from David Cook under
and as provided in the Stock Purchase Agreement. Borrower will not, without
the prior written consent of Bank, supplement, amend, modify or waive in any
way any provision of the Stock Purchase Agreement. Borrower agrees and
acknowledges that foregoing right of Borrower to purchase the Put Shares is
not a waiver of any Event of Default which might be created by such purchase,
other than the general prohibition on dividends, distributions or other
payments set forth in the first sentence of this Section 7.6 and as otherwise
set forth in Section 7.8 below.

                  7.7  INVESTMENTS. Directly or indirectly acquire or own, or
make any Investment in or to any Person, or permit any of its Subsidiaries so
to do, other than Permitted Investments.

                  7.8  TRANSACTIONS WITH AFFILIATES. Other than Borrower's
right to purchase the Put Shares pursuant to and in accordance with Section
7.6 above, directly or indirectly enter into or permit to exist any material
transaction with any Affiliate of Borrower except for transactions that are in
the ordinary course of Borrower's

                                      24

<PAGE>

business, upon fair and reasonable terms that are no less favorable to
Borrower than would be obtained in an arm's length transaction with a
nonaffiliated Person. Borrower agrees and acknowledges that right of Borrower
to purchase the Put Shares pursuant to and in accordance with Section 7.6
above is not a waiver of any Event of Default which might be created by such
purchase, other than the general prohibition on any material transaction with
an Affiliate of Borrower set forth in the first sentence of this Section 7.8
and as otherwise set forth in Section 7.6 above.

                  7.9  INTELLECTUAL PROPERTY AGREEMENTS. Permit the inclusion
in any material contract to which it becomes a party of any provisions that
could or might in any way prevent the creation of a security interest in
Borrower's rights and interests in any property included within the definition
of the Intellectual Property Collateral acquired under such contracts, except
to the extent that such provisions are necessary in Borrower's exercise of its
reasonable business judgement.

                  7.10 SUBORDINATED DEBT. Make any payment in respect of any
Subordinated Debt, or permit any of its Subsidiaries to make any such payment,
except in compliance with the terms of such Subordinated Debt, or amend any
provision contained in any documentation relating to the Subordinated Debt
without Bank's prior written consent.

                  7.11 INVENTORY. Store the Inventory with a bailee,
warehouseman, or similar party unless Bank has received a pledge of any
warehouse receipt covering such Inventory. Except for Inventory sold in the
ordinary course of business and except for such other locations as Bank may
approve in writing, Borrower shall keep the Inventory only at the location set
forth in Section 10 hereof and such other locations of which Borrower gives
Bank prior written notice and as to which Borrower signs and files a financing
statement where needed to perfect Bank's security interest.

                  7.12 COMPLIANCE. Become an "investment company" or a company
controlled by an "investment company," within the meaning of the Investment
Company Act of 1940, or become principally engaged in, or undertake as one of
its important activities, the business of extending credit for the purpose of
purchasing or carrying margin stock, or use the proceeds of any Advance for
such purpose; fail to meet the minimum funding requirements of ERISA; permit a
Reportable Event or Prohibited Transaction, as defined in ERISA, to occur;
fail to comply with the Federal Fair Labor Standards Act or violate any other
law or regulation, which violation could have a Material Adverse Effect or a
material adverse effect on the Collateral or the priority of Bank's Lien on
the Collateral; or permit any of its Subsidiaries to do any of the foregoing.

                  7.13 ABANDONMENT OF INTELLECTUAL PROPERTY. If an Event of
Default has occurred and is continuing, allow any Trademarks, Patents,
Copyrights, or Mask Works to be abandoned, forfeited or dedicated to the
public without the written consent of Bank.

         8. EVENTS OF DEFAULT

                  Any one or more of the following events shall constitute an
Event of Default by Borrower under this Agreement:

                  8.1  PAYMENT DEFAULT. If Borrower fails to pay, within five
(5) calendar days of when due, any of the Obligations.

                  8.2  COVENANT DEFAULT.

                       (a) If Borrower fails to perform any obligation under
Sections 6.3, 6.7, 6.8, 6.9 or 6.10 or violates any of the covenants contained
in Article 7 of this Agreement, or

                       (b) If Borrower fails or neglects to perform, keep, or
observe any other material term, provision, condition, covenant, or agreement
contained in this Agreement, in any of the Loan Documents, or in any other
present or future agreement between Borrower and Bank and as to any default
under such other term, provision, condition, covenant or agreement that can
be cured, has failed to cure such default within ten (10) days after the
occurrence thereof; provided, however, that if the default cannot by its
nature be cured within the ten (10) day period or cannot after diligent
attempts by Borrower be cured within such ten (10) day period, and such
default is likely to be cured within a reasonable time, then Borrower shall
have an additional reasonable period (which shall not in any case exceed
thirty (30) days) to attempt to cure such default, and within such reasonable
time period the failure to have cured such default shall not be deemed an
Event of Default (provided that no Advances will be required to be made
during such cure period).

                  8.3  MATERIAL ADVERSE CHANGE. If there (i) occurs a
material adverse change in the business, operations, or condition (financial
or otherwise) of the Borrower, or (ii) is a material impairment of the
prospect of repayment of any portion of the Obligations or (iii) is a
material impairment of the value or priority of Bank's security interests in
the Collateral;

                  8.4  ATTACHMENT. If any material portion of Borrower's
assets is attached, seized, subjected to a writ or distress warrant, or is
levied upon, or comes into the possession of any trustee, receiver or person
acting in a similar capacity and such attachment, seizure, writ or distress
warrant or levy has not been removed, discharged or rescinded within thirty
(30) days, or if Borrower is enjoined, restrained, or in any way prevented by
court order from continuing to conduct all or any material part of its
business affairs, or if a judgment or other claim becomes a lien or
encumbrance upon any material portion of Borrower's assets, or if a notice of
lien, levy, or assessment is filed of record with respect to any of
Borrower's assets by the United States Government, or any department, agency,
or instrumentality thereof, or by any state, county, municipal, or
governmental agency, and the same is not paid within thirty (30) days after
Borrower receives notice thereof, provided that none of the


                                      26
<PAGE>


foregoing shall constitute an Event of Default where such action or event is
stayed or an adequate bond has been posted pending a good faith contest by
Borrower (provided that no Credit Extensions will be required to be made
during such cure period);

                  8.5   INSOLVENCY. If Borrower becomes insolvent, or if an
Insolvency Proceeding is commenced by Borrower, or if an Insolvency
Proceeding is commenced against Borrower and is not dismissed or stayed
within forty-five (45) days (provided that no Credit Extensions will be made
prior to the dismissal of such Insolvency Proceeding);

                  8.6   OTHER AGREEMENTS. If there is a default in any
agreement to which Borrower is a party with a third party or parties
resulting in the exercise of a right by such third party or parties to
accelerate the maturity of any Indebtedness in an amount in excess of One
Hundred Thousand and No/100 Dollars ($100,000.00) or that could have a
Material Adverse Effect;

                  8.7   SUBORDINATED DEBT. If Borrower makes any payment on
account of Subordinated Debt, except to the extent such payment is allowed
under any subordination agreement entered into with Bank;

                  8.8   JUDGMENTS. If a judgment or judgments for the payment
of money in an amount, individually or in the aggregate, of at least One
Hundred Thousand and No/100 Dollars ($100,000.00) shall be rendered against
Borrower and shall remain unsatisfied and unstayed for a period of ten (10)
days (provided that no Credit Extensions will be made prior to the
satisfaction or stay of such judgment);

                  8.9   MISREPRESENTATIONS. If any material misrepresentation
or material misstatement exists now or hereafter in any warranty or
representation set forth herein or in any certificate or writing delivered to
Bank by Borrower or any Person acting on Borrower's behalf pursuant to this
Agreement or to induce Bank to enter into this Agreement or any other Loan
Document; or

                  8.10  GUARANTY. Any guaranty of all or a portion of the
Obligations ceases for any reason to be in full force and effect, or any
Guarantor fails to perform any obligation under any guaranty of all or a
portion of the Obligations, or any material misrepresentation or material
misstatement exists now or hereafter in any warranty or representation set
forth in any guaranty of all or a portion of the Obligations or in any
certificate delivered to Bank in connection with such guaranty, or any of the
circumstances described in Sections 8.4, 8.5 or 8.8 occur with respect to any
Guarantor.

         9.  BANK'S RIGHTS AND REMEDIES

                  9.1   RIGHTS AND REMEDIES. Upon the occurrence and during
the continuance of an Event of Default, Bank may, at its election, without
notice of its


                                      27
<PAGE>


election and without demand, do any one or more of the following, all of
which are authorized by Borrower:

                        (a) Declare all Obligations, whether evidenced by
this Agreement, by any of the other Loan Documents, or otherwise, immediately
due and payable (provided that upon the occurrence of an Event of Default
described in Section 8.5 all Obligations shall become immediately due and
payable without any action by Bank);

                        (b) Cease advancing money or extending credit to or
for the benefit of Borrower under this Agreement or under any other agreement
between Borrower and Bank;

                        (c) Demand that Borrower (i) deposit cash with Bank
in an amount equal to the amount of any Letters of Credit remaining undrawn, as
collateral security for the repayment of any future drawings under such Letters
of Credit, and Borrower shall forthwith deposit and pay such amounts, and (ii)
pay in advance all Letters of Credit fees scheduled to be paid or payable over
the remaining term of the Letters of Credit;

                        (d) Settle or adjust disputes and claims directly
with account debtors for amounts, upon terms and in whatever order that Bank
reasonably considers advisable;

                        (e) Without notice to or demand upon Borrower, make
such payments and do such acts as Bank considers necessary or reasonable to
protect its security interest in the Collateral. Borrower agrees to assemble the
Collateral if Bank so requires, and to make the Collateral available to Bank as
Bank may designate. Borrower authorizes Bank to enter the premises where the
Collateral is located, to take and maintain possession of the Collateral, or any
part of it, and to pay, purchase, contest, or compromise any encumbrance,
charge, or lien which in Bank's determination appears to be prior or superior to
its security interest and to pay all expenses incurred in connection therewith.
With respect to any of Borrower's premises, Borrower hereby grants Bank a
license to enter such premises and to occupy the same, without charge in order
to exercise any of Bank's rights or remedies provided herein, at law, in equity,
or otherwise;

                        (f) Without notice to Borrower, set off and apply to
the Obligations any and all (i) balances and deposits of Borrower held by Bank,
or (ii) indebtedness at any time owing to or for the credit or the account of
Borrower held by Bank;

                        (g) Ship, reclaim, recover, store, finish, maintain,
repair, prepare for sale, advertise for sale, and sell (in the manner provided
for herein) the Collateral. Bank is hereby granted a non-exclusive, royalty-free
license or other right, solely pursuant to the provisions of this Section 9.1,
to use, without charge,


                                      28
<PAGE>


Borrower's labels, patents, copyrights, mask works, rights of use of any
name, trade secrets, trade names, trademarks, service marks, and advertising
matter, or any property of a similar nature, as it pertains to the
Collateral, in completing production of, advertising for sale, and selling
any Collateral and, in connection with Bank's exercise of its rights under
this Section 9.1, Borrower's rights under all licenses and all franchise
agreements shall inure to Bank's benefit;

                        (h) Sell the Collateral at either a public or private
sale, or both, by way of one or more contracts or transactions, for cash or on
terms, in such manner and at such places (including Borrower's premises) as Bank
determines is commercially reasonable, and apply the proceeds thereof to the
Obligations in whatever manner or order it deems appropriate;

                        (i) Bank may credit bid and purchase at any public
sale, or at any private sale as permitted by law; and

                        (j) Any deficiency that exists after disposition of
the Collateral as provided above will be paid immediately by Borrower.

                        (k) Bank shall have a non-exclusive, royalty-free
license to use the Intellectual Property Collateral to the extent reasonably
necessary to permit Bank to exercise its rights and remedies upon the occurrence
of an Event of Default.

                  9.2   POWER OF ATTORNEY. Effective only upon the occurrence
and during the continuance of an Event of Default, Borrower hereby
irrevocably appoints Bank (and any of Bank's designated officers, or
employees) as Borrower's true and lawful attorney to: (a) send requests for
verification of Accounts or notify account debtors of Bank's security
interest in the Accounts; (b) endorse Borrower's name on any checks or other
forms of payment or security that may come into Bank's possession; (c) sign
Borrower's name on any invoice or bill of lading relating to any Account,
drafts against account debtors, schedules and assignments of Accounts,
verifications of Accounts, and notices to account debtors; (d) make, settle,
and adjust all claims under and decisions with respect to Borrower's policies
of insurance; and (e) settle and adjust disputes and claims respecting the
Accounts directly with account debtors, for amounts and upon terms which Bank
determines to be reasonable; (f) modify, in its sole discretion, any
intellectual property security agreement entered into between Borrower and
Bank without first obtaining Borrower's approval of or signature to such
modification by amending Exhibit A, Exhibit B, Exhibit C and Exhibit D,
thereof, as appropriate, to include reference to any right, title or interest
in any Copyrights, Patents, Trademarks, Mask Works acquired by Borrower after
the execution hereof or to delete any reference to any right, title or
interest in any Copyrights, Patents, Trademarks, or Mask Works in which
Borrower no longer has or claims any right, title or interest; (g) file, in
its sole discretion, one or more financing or continuation statements and
amendments thereto, relative to any of the Collateral without the signature
of Borrower where permitted by law; and (h) transfer the Intellectual
Property Collateral into the name of Bank or a third party to the extent
permitted under the Code provided Bank may exercise such power of attorney to
sign


                                      29
<PAGE>


the name of Borrower on any of the documents described in Section 4.2
regardless of whether an Event of Default has occurred. The appointment of
Bank as Borrower's attorney in fact, and each and every one of Bank's rights
and powers, being coupled with an interest, is irrevocable until all of the
Obligations have been fully repaid and performed and Bank's obligation to
provide advances hereunder is terminated.

                  9.3   ACCOUNTS COLLECTION. Upon the occurrence and during
the continuance of an Event of Default, Bank may notify any Person owing
funds to Borrower of Bank's security interest in such funds and verify the
amount of such Account. Borrower shall collect all amounts owing to Borrower
for Bank, receive in trust all payments as Bank's trustee, and if requested
or required by Bank, immediately deliver such payments to Bank in their
original form as received from the account debtor, with proper endorsements
for deposit.

                  9.4   BANK EXPENSES. If Borrower fails to pay any amounts
or furnish any required proof of payment due to third persons or entities, as
required under the terms of this Agreement, then Bank may do any or all of
the following: (a) make payment of the same or any part thereof; (b) set up
such reserves under the Committed Revolving Line as Bank deems necessary to
protect Bank from the exposure created by such failure; or (c) obtain and
maintain insurance policies of the type discussed in Section 6.6 of this
Agreement, and take any action with respect to such policies as Bank deems
prudent. Any amounts so paid or deposited by Bank shall constitute Bank
Expenses, shall be immediately due and payable, and shall bear interest at
the then applicable rate hereinabove provided, and shall be secured by the
Collateral. Any payments made by Bank shall not constitute an agreement by
Bank to make similar payments in the future or a waiver by Bank of any Event
of Default under this Agreement.

                  9.5   BANK'S LIABILITY FOR COLLATERAL. So long as Bank
complies with reasonable banking practices, Bank shall not in any way or
manner be liable or responsible for: (a) the safekeeping of the Collateral;
(b) any loss or damage thereto occurring or arising in any manner or fashion
from any cause; (c) any diminution in the value thereof; or (d) any act or
default of any carrier, warehouseman, bailee, forwarding agency, or other
person whomsoever. All risk of loss, damage or destruction of the Collateral
shall be borne by Borrower.

                  9.6   REMEDIES CUMULATIVE. Bank's rights and remedies under
this Agreement, the Loan Documents, and all other agreements shall be
cumulative. Bank shall have all other rights and remedies, not expressly set
forth herein, and as provided under the Code, by law, or in equity. No
exercise by Bank of one right or remedy shall be deemed an election, and no
waiver by Bank of any Event of Default on Borrower's part shall be deemed a
continuing waiver. No delay by Bank shall constitute a waiver, election, or
acquiescence by it. No waiver by Bank shall be effective unless made in a
written document signed on behalf of Bank and then shall be effective only in
the specific instance and for the specific purpose for which it was given.


                                      30
<PAGE>


                  9.7   DEMAND; PROTEST. Borrower waives demand, protest,
notice of protest, notice of default or dishonor, notice of payment and
nonpayment, notice of any default, notice of intent to accelerate, notice of
acceleration, nonpayment at maturity, release, compromise, settlement,
extension, or renewal of accounts, documents, instruments, chattel paper, and
guarantees at any time held by Bank on which Borrower may in any way be
liable.

                  12.4  SEVERABILITY OF PROVISIONS. Each provision of this

the same Agreement.

                  12.7  SURVIVAL. All covenants, representations and
warranties made in this Agreement shall continue in full force and effect so

indemnify Bank with respect to the expenses, damages, losses, costs and

<PAGE>

                           (a) Subject to and upon the terms and conditions of
this Agreement, Bank shall make a Term Loan available to Borrower.

                           (b) When Borrower desires to obtain the Credit
Extension, Borrower will notify Bank by facsimile transmission or telephone no
later than 3:00 p.m. Pacific time, on the Business Day that the Credit
Extension is to be made. The notification shall be promptly confirmed by a
Payment/Advance Form in substantially the form of EXHIBIT B hereto. Bank is
authorized to make the Credit Extension under this Agreement, based upon
instructions received from a Responsible Officer or a designee of a
Responsible Officer. Bank shall be entitled to rely on any telephonic notice
given by a person who Bank reasonably believes to be a Responsible Officer or
a designee thereof, and Borrower shall indemnify and hold Bank harmless for
any damages or loss suffered by Bank as a result of such reliance. Bank will
credit the amount of the Credit Extension made under this SECTION 2.1 to
Borrower's deposit account.

                           (c) The Term Loan shall terminate on the Term
Maturity Date, at which time all Obligations under this SECTION 2.1 and other
amounts due under this Agreement (except as otherwise expressly specified
herein) shall be immediately due and payable.

         2.2      INTEREST RATES, PAYMENTS, AND CALCULATIONS.

                           (a) INTEREST RATE. Except as set forth in SECTION
2.2(B), Credit Extensions shall bear interest, on the average daily balance
thereof, at a per annum rate equal to twelve percent (12%).

                           (b) DEFAULT RATE. All Obligations shall bear
interest, from and after the occurrence of an Event of Default, at the
"Default Interest Rate." The Default Interest Rate shall be, at Bank's option,
(i) the Maximum Lawful Rate, if such Maximum Lawful Rate is established by
applicable law: or (ii) the interest rate applicable immediately prior to the
occurrence of the Event of Default plus five (5) percentage points, if no
Maximum Lawful Rate is established by applicable law: or (iii) eighteen
percent (18%) per annum: or (iv) such lesser rate of interest as Bank's, its
sole discretion may choose to charge: but never more than the Maximum Lawful
Rate or at a rate that would cause the total interest contracted for, charged
or received by Bank to exceed the Maximum Lawful Amount.

                           (c) PAYMENTS. Interest hereunder shall be due and
payable on each Payment Date. Any interest not paid when due shall be
compounded by becoming a part of the Obligations, and such interest shall
thereafter accrue interest at the rate then applicable hereunder.

                           (d) COMPUTATION.

                               (i) SPREADING OF INTEREST. Because of the
possibility of irregular periodic balances of principal, the fluctuating
nature of the interest rate, or premature payment, the total interest that
will accrue under this Agreement cannot be determined in advance. Bank does
not intend to contract for charge or receive more than the Maximum Lawful Rate
or Maximum Lawful Amount permitted by applicable state or federal law, and to
prevent such an occurrence Bank and Borrower agree that all amounts of
interest, whenever contracted for, charged or received by Bank, with respect
to the loan of money evidenced by the Loan

                                       7

<PAGE>

Documents, shall be spread, prorated or allocated over the full period of time
the Obligations are unpaid, including the period of any renewal or extension
thereof. If the maturity of the Obligations is accelerated for any reason
whether as a lawsuit or an Event of Default or otherwise prior to the full
stated term, the total amount of interest contracted for, charged or received
to the time of such demand shall be spread, prorated or allocated along with
any interest thereafter accruing over the full period of time that the
Obligations thereafter remain unpaid for the purpose of determining if such
interest exceeds the Maximum Lawful Amount.

                               (ii) EXCESS INTEREST. At maturity (whether by
acceleration or otherwise) or on earlier final payment of the Obligations,
Bank shall compute the total amount of interest that has been contracted for,
charged or received by Bank or payable by Borrower hereunder and compare such
amount to the Maximum Lawful Amount that could have been contracted for,
charged or received by Bank. If such computation reflects that the total
amount of interest that has been contracted for, charged or received by Bank
or payable by Borrower exceeds the Maximum Lawful Amount, then Bank shall
apply such excess to the reduction of the principal balance and not to the
payment of interest: or if such excess interest exceeds the unpaid principal
balance, such excess shall be refunded to Borrower. This provision concerning
the crediting or refund of excess interest shall control and take precedence
over all other agreements between Borrower and Bank so that under no
circumstances shall the total interest contracted for, charged or received by
Bank exceed the Maximum Lawful Amount.

                               (iii) DAILY COMPUTATION OF INTEREST. To the
extent permitted by applicable law, Bank at its option may either (i)
calculate the per diem interest rate or amount based on the actual number of
days in the year (365 or 366, as the case may be), and charge that per diem
interest rate or amount each day, or (ii) calculate the per diem interest rate
or amount as if each year has only 360 days, and charge that per diem interest
rate or amount each day for the actual number of days of the year (365 or 366
as the case may be). If the Loan Documents call for monthly payments, Bank at
its option may determine the payment amount based on the assumption that each
year has only 360 days and each month has 30 days. In no event shall Bank
compute the interest in a manner that would cause Bank to contract for, charge
or receive interest that would exceed the Maximum Lawful Rate or the Maximum
Lawful Amount.

         2.3 CREDITING PAYMENTS. Prior to the occurrence of an Event of
Default, Bank shall credit a wire transfer of funds, check or other item of
payment to such deposit account or Obligation as Borrower specifies. After the
occurrence of an Event of Default, the receipt by Bank of any wire transfer of
funds, check, or other item of payment, whether directed to Borrower's deposit
account with Bank or to the Obligations or otherwise, shall be immediately
applied to conditionally reduce Obligations, but shall not be considered a
payment in respect of the Obligations unless such payment is of immediately
available federal funds or unless and until such check or other item of
payment is honored when presented for payment. Notwithstanding anything to the
contrary contained herein, any wire transfer or payment received by Bank after
12:00 noon Pacific time shall be deemed to have been received by Bank as of
the opening of business on the immediately following Business Day. Whenever
any payment to Bank under the Loan Documents would otherwise be due (except by
reason of acceleration) on a date that is not a Business Day, such payment
shall instead be due on the next Business Day, and additional fees or
interest, as the case may be, shall accrue and be payable for the period of
such extension.

the date hereof, all Bank Expenses, including reasonable attorneys' fees and
expenses, as and when they become due.

         2.5 ADDITIONAL COSTS. In case any law, after the date hereof, any
regulation, treaty or official directive or the interpretation or application
thereof by any court or any governmental authority charged with the
administration thereof or the compliance with any guideline or request of any
central bank or other governmental authority (whether or not having the force
of law):

                   (a) subjects Bank to any tax with respect to payments of
principal or interest or any other amounts payable hereunder by Borrower or
otherwise with respect to the transactions contemplated hereby (except for
taxes on the overall net income of Bank imposed by the United States of
America or any political subdivision thereof);

                   (b) imposes, modifies or deems applicable any deposit
insurance, reserve, special deposit or similar requirement against assets held
by, or deposits in or for the account of, or loans by, Bank: or

                   (c) imposes upon Bank any other condition with respect to
its performance under this Agreement, and the result of any of the foregoing
is to increase the cost to Bank, reduce the income receivable by Bank or
impose any expense upon Bank with respect to the Obligations, Bank shall
notify Borrower thereof within one hundred eighty (180) days of Bank incurring
any such reduced income or increased cost or expense. Borrower agrees to pay
to Bank the amount of such increase in cost, reduction in income or additional
expense as and when such cost, reduction or expense is incurred or determined,
upon presentation by Bank of a statement of the amount and setting forth
Bank's calculation thereof, all in reasonable detail, which statement shall be
deemed true and correct absent manifest error.

         2.6 TERM. Except as otherwise set forth herein, this Agreement shall
become effective on the Closing Date and, subject to SECTION 12.7, shall
continue in full force and effect for a term ending on the Term Maturity Date.
Notwithstanding the foregoing, Bank shall have the right to terminate its
obligation to make Credit Extensions under this Agreement immediately and
without notice upon the occurrence and during the continuance of an Event of
Default.

                                       9

continuing security interest in all presently existing and hereafter acquired
or arising Collateral and all proceeds thereof, in order to secure prompt
payment of any and all Obligations and in order to secure prompt performance
by Borrower of each of its covenants and duties under the Loan Documents.
Except as set forth in the Schedule, such security interest constitutes a
valid, first priority security interest in the presently existing Collateral,
and will constitute a valid, first priority security interest in Collateral
acquired after the date hereof. Borrower acknowledges that following the
occurrence and during the continuance of an Event of Default hereunder Bank
may place a "hold" on any deposit account pledged as Collateral to secure the
Obligations. Notwithstanding termination of this Agreement, Bank's Lien on the

         Borrower represents and warrants as follows:

         5.1 DUE ORGANIZATION AND QUALIFICATION. Borrower and each Subsidiary
is a corporation duly existing and in good standing under the laws of its
state of incorporation and qualified and licensed to do business in, and is in
good standing in Texas, and in any other state in which the conduct of its
business or its ownership of property requires that it be so qualified where
the failure to so qualify would result in a Material Adverse Effect.

         5.2 DUE AUTHORIZATION: NO CONFLICT. The execution, delivery, and
performance of the Loan Documents are within Borrower's powers, have been duly
authorized and are not in conflict with nor constitute a breach of any
provision contained in Borrower's Articles of Incorporation or Bylaws, nor
will they constitute an event of default under any material


                                     11

<PAGE>

agreement to which Borrower is a party or by which Borrower is bound. Borrower
is not in default under any agreement to which it is a party or by which it is
bound, which default could have a Material Adverse Effect.

         5.3 NO PRIOR ENCUMBRANCES. Borrower has good and indefeasible title
to the Collateral free and clear of Liens, except for Permitted Liens.

         5.4 MERCHANTABLE INVENTORY. All Inventory is in all material respects
of good and marketable quality, free from all material defects.

         5.5 INTELLECTUAL PROPERTY. Borrower is the owner of the Patents,
Trademarks, Copyrights and Mask Works subject to licenses granted by Borrower
to its customers in the ordinary course of business. To Borrower's knowledge,
each of the Patents is valid and enforceable, and no part of the Intellectual
Property Collateral has been judged invalid or unenforceable, in whole or in
part, and no claim has been made that any part of the Intellectual Property
Collateral violates the rights of any third party. Except for and upon the
filing with the United States Patent and Trademark Office with respect to the
Patents and Trademarks and the Register of Copyrights with respect to the
Copyrights and Mask Works necessary to perfect the security interests created
hereunder, and except as has been already made or obtained, no authorization,
approval or other action by, and no notice to or filing with, any United
States governmental authority or United States regulatory body is required
either (i) for the grant by Borrower of the security interest granted hereby
or for the execution, delivery or performance of Loan Documents by Borrower in
the United States or (ii) for the perfection in the United States or the
exercise by Bank of its rights and remedies hereunder.

         5.6 NAME: LOCATION OF CHIEF EXECUTIVE OFFICE. Except as disclosed in
the Schedule, Borrower has not done business and will not without at least
thirty (30) days prior written notice to Bank do business under any name other

of Borrower is located at the address indicated in SECTION 10 hereof.

         5.7 LITIGATION. Except as set forth in the Schedule, there are no
actions or proceedings pending, or, to Borrower's knowledge, threatened by or
against Borrower or any Subsidiary before any court or administrative agency
in which an adverse decision could have a Material Adverse Effect on
Borrower's interest or Bank's security interest in the Collateral.

         5.8 NO MATERIAL ADVERSE CHANGE IN FINANCIAL STATEMENTS. All
consolidated financial statements related to Borrower and any Subsidiary that
have been delivered by Borrower to Bank fairly present in all material
respects Borrower's consolidated financial condition as of the date thereof
and Borrower's consolidated results of operations for the period then ended.
There has not been a material adverse change in the consolidated financial
condition of Borrower since the date of the most recent of such financial
statements submitted to Bank on or about the Closing Date.

         5.9 SOLVENCY. The fair saleable value of Borrower's assets (including
goodwill minus disposition costs) exceeds the fair value of its liabilities;
the Borrower is not left with

                                     12

<PAGE>

unreasonably small capital after the transactions contemplated by this
Agreement; and Borrower is able to pay its debts (including trade debts) as
they mature.

         5.10 REGULATORY COMPLIANCE. Borrower and each Subsidiary has met the
minimum funding requirements of ERISA with respect to any employee benefit
plans subject to ERISA. No event has occurred resulting from Borrower's
failure to comply with ERISA that is reasonably likely to result in Borrower's
incurring any liability that could have a Material Adverse Effect. Borrower is
not an "investment company" or a company "controlled" by an "investment
company" within the meaning of the Investment Company Act of 1940. Borrower is
not engaged principally, or as one of its important activities, in the
business of extending credit for the purpose of purchasing or carrying margin

         6.1 GOOD STANDING. Borrower shall maintain its and each of its
Subsidiaries' corporate existence and good standing in its jurisdiction of

         6.3 FINANCIAL STATEMENTS, REPORTS, CERTIFICATES Borrower shall
deliver to Bank: (a) as soon as available, but in any event within thirty (30)

make any payment if the amount or validity of such payment is (i) contested in
good faith by appropriate proceedings, (ii) is reserved against (to the extent
required by GAAP) by Borrower and (iii) no Lien other than a Permitted Lien
results.

                           (a) Borrower, at its expense, shall keep the
Collateral insured against loss or damage by fire, theft, explosion,
sprinklers, and all other hazards and risks, and in-such amounts, as
ordinarily insured against by other owners in similar businesses conducted in
the locations where Borrower's business is conducted on the date hereof.
Borrower shall also maintain insurance relating to Borrower's ownership and
use of the Collateral in amounts and of a type that are customary, to
businesses similar to Borrower's.

                           (b) All such policies of insurance shall be in such
form, with such companies, and in such amounts as are reasonably satisfactory
to Bank. All such policies of property insurance shall contain a lender's loss
payable endorsement, in a form satisfactory to Bank, showing Bank as an
additional loss payee thereof and all liability insurance policies shall show
the Bank as an additional insured, and shall specify that the insurer must
give at least fifteen (15) days notice to Bank before canceling its policy for
any reason. At Bank's request, Borrower shall deliver to Bank certified copies
of such policies of insurance and evidence of the payments of all premiums
therefor. All proceeds payable under any such policy shall, at the option of
Bank, be payable to Bank to be applied on account of the Obligations.

additions to the intellectual property rights listed in the Intellectual
Property Security Agreement and exhibits thereto.

                           (d) Bank shall have the right, but not the
obligation, to take, at Borrower's sole expense, any actions that Borrower is
required under this SECTION 6.7 to take but which Borrower fails to take,
after fifteen (15) days notice to Borrower. BORROWER SHALL REIMBURSE AND

will be made if such subordinations are not delivered by the date set forth
above.

7.       NEGATIVE COVENANTS

         Borrower covenants and agrees that, so long as any Credit Extension

Norris or Graham Glass ceases to be an employee or director of Borrower and
replacements reasonably satisfactory to Bank are not made in within thirty
(30) days. Borrower will not, without at least fifteen (15) days prior written

substantially all of the capital stock or property of another Person.

         7.4 INDEBTEDNESS. Create, incur, assume or be or remain liable with
respect to any Indebtedness, or permit any Subsidiary so to do, other than

         7.6 DISTRIBUTIONS. Pay any dividends or make any other distribution
or payment on account of or in redemption, retirement or purchase of any
capital stock: provided, Borrower may purchase (i) the Put Shares (as defined
in that certain Stock Purchase Agreement ("Stock Purchase Agreement") dated
August 21, 1996 between David Cook and Borrower) from David Cook under and as
provided in the Stock Purchase Agreement and (ii) the Put (as defined in that
certain Warrant Subscription Agreement ("Subscription Agreement") between
Bank, Borrower, and Borrower's shareholders of even date herewith) from Bank
and as provided in the Subscription Agreement. Borrower will not, without the
prior written consent of Bank, supplement, amend, modify or waive in any way
any provision of the Stock Purchase Agreement. Borrower agrees and
acknowledges that the foregoing right of Borrower to purchase the Put Shares
is not a waiver of any Event of Default which might be created by such

other payments set forth in the first sentence of this SECTION 7.6 and as
otherwise set forth in SECTION 7.8 below.

Agreement, directly or indirectly enter into or permit to exist any material
transaction with any Affiliate of Borrower except for transactions that are in
the ordinary course of Borrower's business, upon fair and reasonable terms
that are no less favorable to Borrower than would be obtained in an arm's
length transaction with a nonaffiliated Person. Borrower agrees and
acknowledges that right of Borrower to purchase the Put Shares pursuant to and
in accordance with SECTION 7.6 above is not a waiver of any Event of Default
which might be created by such purchase, other than the general prohibition on
any material transaction with an Affiliate of Borrower set forth in the first
sentence of this SECTION 7.8 and as otherwise set forth in SECTION 7.6 above.

         7.9 INTELLECTUAL PROPERTY AGREEMENTS. Permit the inclusion in any
material contract to which it becomes a party of any provisions that could or

                                      17

needed to perfect Bank's security interest.

controlled by an "investment company," within the meaning of the Investment
Company Act of 1940, or become principally engaged in, or undertake as one of
its important activities, the business of extending credit for the purpose of
purchasing or carrying margin stock, or use the proceeds of any Credit
Extension for such purpose; fail to meet the minimum funding requirements of
ERISA; permit a Reportable Event or Prohibited Transaction, as defined in
ERISA to occur; fail to comply with the Federal Fair Labor Standards Act or
violate any other law or regulation, which violation could have a Material
Adverse Effect or a material adverse effect on the Collateral or the priority
of Bank's Lien on the Collateral; or permit any of its Subsidiaries to do any
of the foregoing.

         7.13 ABANDONMENT OF INTELLECTUAL PROPERTY. If an Event of Default

Mask Works to be abandoned, forfeited or dedicated to the public without the
written consent of Bank.

8.       EVENTS OF DEFAULT

         Any one or more of the following events shall constitute an Event of

calendar days of when due, any of the Obligations.

         8.2  COVENANT DEFAULT.

                           (a) If Borrower fails to perform any obligation
under SECTIONS 6.3, or 6.7 or violates any of the covenants contained in
Article 7 of this Agreement, or

                           (b) If Borrower fails or neglects to perform, keep,
or observe any other material term, provision, condition, covenant, or
agreement contained in this Agreement, in any of the Loan Documents, or in any
other present or future agreement between Borrower and Bank and as to any
default under such other term, provision, condition, covenant or agreement
that can be cured, has failed to cure such default within ten (10) days after
the occurrence thereof;

                                      18

<PAGE>

provided, however, that if the default cannot by its nature be cured within
the ten (10) day period or cannot after diligent attempts by Borrower be cured
within such ten (10) day period, and such default is likely to be cured within
a reasonable time, then Borrower shall have an additional reasonable period
(which shall not in any case exceed thirty (30) days) to attempt to cure such
default, and within such reasonable time period the failure to have cured such
default shall not be deemed an Event of Default (provided that no Credit
Extensions will be required to be made during such cure period).

         8.3 MATERIAL ADVERSE CHANGE. If there (i) occurs a material adverse
change in the business, operations, or condition (financial or otherwise) of
the Borrower, or (ii) is a material impairment of the prospect of repayment of

or priority of Bank's security interests in the Collateral;

         8.4 ATTACHMENT. If any material portion of Borrower's assets is

or comes into the possession of any trustee, receiver or person acting in a
similar capacity and such attachment, seizure, writ or distress warrant or
levy has not been removed, discharged or rescinded within thirty (30) days, or
if Borrower is enjoined, restrained, or in any way prevented by court order
from continuing to conduct all or any material part of its business affairs,
or if a judgment or other claim becomes a lien or encumbrance upon any
material portion of Borrower's assets, or if a notice of lien, levy, or
assessment is filed of record with respect to any of Borrower's assets by the
United States Government, or any department, agency, or instrumentality
thereof, or by any state, county, municipal, or governmental agency, and the
same is not paid within thirty (30) days after Borrower receives notice
thereof, provided that none of the foregoing shall constitute an Event of
Default where such action or event is stayed or an adequate bond has been
posted pending a good faith contest by Borrower (provided that no Credit
Extensions will be required to be made during such cure period).

         8.5 INSOLVENCY. If Borrower becomes insolvent, or if an Insolvency
Proceeding is commenced by Borrower, or if an Insolvency Proceeding is
commenced against Borrower and is not dismissed or stayed within forty-five
(45) days (provided that no Credit Extensions will be made prior to the
dismissal of such Insolvency Proceeding).

         8.6 OTHER AGREEMENTS. If there is a default in any agreement to which
Borrower is a party with a third party or parties resulting in the exercise of
a right by such third party or parties to accelerate the maturity of any
Indebtedness in an amount in excess of One Hundred Thousand and No/100 Dollars
($100,000.00) or that could have a Material Adverse Effect;

that certain Loan and Security Agreement by and between Bank and Borrower,
dated as of February 9, 1998 (the "Senior Loan Agreement")) occurs under the
Senior Loan Agreement;


                                      19

<PAGE>

         8.9  JUDGMENTS. If a judgment or judgments for the payment of money in
an amount, individually or in the aggregate, of at least One Hundred Thousand
and No/100 Dollars ($100,000.00) shall be rendered against Borrower and shall
remain unsatisfied and unstayed for a period of ten (10) days (provided that no
Credit Extensions will be made prior to the satisfaction or stay of such
judgment); or

         8.10 MISREPRESENTATIONS. If any material misrepresentation or material
misstatement exists now or hereafter in any warranty or representation set forth
herein or in any certificate or writing delivered to Bank by Borrower or any
Person acting on Borrower's behalf pursuant to this Agreement or to induce Bank
to enter into this Agreement or any other Loan Document.

9.       BANK'S RIGHTS AND REMEDIES

         9.1  RIGHTS AND REMEDIES. Upon the occurrence and during the
continuance of an Event of Default, Bank may, at its election, without notice
of its election and without demand, do any one or more of the following, all
of which are authorized by Borrower:

                     (a) Declare all Obligations, whether evidenced by this
Agreement, by any of the other Loan Documents, or otherwise, immediately due
and payable (provided that upon the occurrence of an Event of Default
described in SECTION 8.5 all Obligations shall become immediately due and
payable without any action by Bank);

                     (b) Cease advancing money or extending credit to or for
the benefit of Borrower under this Agreement or under any other agreement
between Borrower and Bank:

                     (c) Settle or adjust disputes and claims directly with
account debtors for amounts, upon terms and in whatever order that Bank
reasonably considers advisable;

                     (d) Without notice to or demand upon Borrower, make such
payments and do such acts as Bank considers necessary or reasonable to
protect its security interest in the Collateral. Borrower agrees to assemble
the Collateral if Bank so requires, and to make the Collateral available to
Bank as Bank may designate. Borrower authorizes Bank to enter the premises
where the Collateral is located, to take and maintain possession of the
Collateral, or any part of it, and to pay, purchase, contest, or compromise
any encumbrance, charge, or lien which in Bank's determination appears to be
prior or superior to its security interest and to pay all expenses incurred
in connection therewith. With respect to any of Borrower's premises, Borrower
hereby grants Bank a license to enter such premises and to occupy the same,
without charge in order to exercise any of Bank's rights or remedies provided
herein, at law, in equity, or otherwise;

                     (e) Without notice to Borrower, set off and apply to the
Obligations any and all (i) balances and deposits of Borrower held by Bank,
or (ii) indebtedness at any time owing to or for the credit or the account of
Borrower held by Bank;

                     (f) Skip, reclaim, recover, store, finish, maintain,
repair, prepare for sale, advertise for sale, and sell (in the manner
provided for herein) the Collateral. Bank is hereby granted a non-exclusive,
royalty-free license or other right, solely pursuant to the provisions of
this SECTION 9.1, to use, without charge, Borrower's labels, patents,
copyrights,


                                      20
<PAGE>


mask works, rights of use of any name, trade secrets, trade names,
trademarks, service marks, and advertising matter, or any property of a
similar nature, as it pertains to the Collateral, in completing production
of, advertising for sale, and selling any Collateral and, in connection with
Bank's exercise of its rights under this SECTION 9.1, Borrower's rights under
all licenses and all franchise agreements shall inure to Bank's benefit;

                     (g) Sell the Collateral at either a public or private
sale, or both, by way of one or more contracts or transactions, for cash or
on terms, in such manner and at such places (including Borrower's premises)
as Bank determines is commercially reasonable, and apply the proceeds thereof
to the Obligations in whatever manner or order it deems appropriate;

                     (h) Bank may credit bid and purchase at any public sale,
or at any private sale as permitted by law; and

                     (i) Any deficiency that exists after disposition of the
Collateral as provided above will be paid immediately by Borrower.

                     (j) Bank shall have a non-exclusive, royalty-free
license to use the Intellectual Property Collateral to the extent reasonably
necessary, to permit Bank to exercise its rights and remedies upon the
occurrence of an Event of Default.

         9.2  POWER OF ATTORNEY. Effective only upon the occurrence and during
the continuance of an Event of Default, Borrower hereby irrevocably appoints
Bank (and any of Bank's designated officers, or employees) as Borrower's true
and lawful attorney to: (a) send requests for verification of Accounts or notify
account debtors of Bank's security interest in the Accounts; (b) endorse
Borrower's name on any checks or other forms of payment or security that may
come into Bank's possession; (c) sign Borrower's name on any invoice or bill of
lading relating to any Account, drafts against account debtors, schedules and
assignments of Accounts, verifications of Accounts, and notices to account
debtors; (d) make, settle, and adjust all claims under and decisions with
respect to Borrower's policies of insurance; and (e) settle and adjust disputes
and claims respecting the Accounts directly with account debtors, for amounts
and upon terms which Bank determines to be reasonable; (f) modify, in its sole
discretion, any intellectual property security agreement entered into between
Borrower and Bank without first obtaining Borrower's approval of or signature to
such modification by amending Exhibit A, Exhibit B, Exhibit C and Exhibit D,
thereof, as appropriate, to include reference to any right, title or interest in
any Copyrights, Patents, Trademarks, Mask Works acquired by Borrower after the
execution hereof or to delete any reference to any right, title or interest in
any Copyrights, Patents, Trademarks, or Mask Works in which Borrower no longer
has or claims any right, title or interest; (g) file, in its sole discretion,
one or more financing or continuation statements and amendments thereto,
relative to any of the Collateral without the signature of Borrower where
permitted by law; and (h) transfer the Intellectual Property Collateral into the
name of Bank or a third party to the extent permitted under the Code provided
Bank may exercise such power of attorney to sign the name of Borrower on any of
the documents described in SECTION 4.2 regardless of whether an Event of Default
has occurred. The appointment of Bank as Borrower's attorney in fact, and each
and every one of Bank's rights and powers, being coupled with an interest, is
irrevocable until all of the Obligations have been fully repaid and performed
and Bank's obligation to provide Credit Extensions hereunder is terminated.

         9.3  ACCOUNTS COLLECTION. Upon the occurrence and during the
continuance of an Event of Default, Bank may notify any Person owing funds to
Borrower of Bank's security interest in such funds and verify the amount of
such Account. Borrower shall collect all amounts owing to Borrower for Bank,
receive in trust all payments as Bank's trustee, and if requested or required
by Bank, immediately deliver such payments to Bank in their original form as
received from the account debtor, with proper endorsements for deposit.

         9.4  BANK EXPENSES. If Borrower fails to pay any amounts or furnish
any required proof of payment due to third persons or entities, as required
under the terms of this Agreement, then Bank may do any or all of the
following: (a) make payment of the same or any part thereof; (b) set up such
reserves under the Term Loan as Bank deems necessary to protect Bank from the
exposure created by such failure; or (c) obtain and maintain insurance
policies of the type discussed in SECTION 6.6 of this Agreement, and take any
action with respect to such policies as Bank deems prudent. Any amounts so
paid or deposited by Bank shall constitute Bank Expenses, shall be
immediately due and payable, and shall bear interest at the then applicable
rate hereinabove provided, and shall be secured by the Collateral. Any
payments made by Bank shall not constitute an agreement by Bank to make
similar payments in the future or a waiver by Bank of any Event of Default
under this Agreement.

         9.5  BANK'S LIABILITY FOR COLLATERAL. So long as Bank complies with
reasonable banking practices, Bank shall not in any way or manner be liable
or responsible for: (a) the safekeeping of the Collateral; (b) any loss or
damage thereto occurring or arising in any manner or fashion from any cause;
(c) any diminution in the value thereof; or (d) any act or default of any
carrier, warehouseman, bailee, forwarding agency, or other person whomsoever.
All risk of loss, damage or destruction of the Collateral shall be borne by
Borrower.

         9.6  REMEDIES CUMULATIVE. Bank's rights and remedies under this
Agreement, the Loan Documents, and all other agreements shall be cumulative.
Bank shall have all other rights and remedies, not expressly set forth
herein, and as provided under the Code, by law, or in equity. No exercise by
Bank of one right or remedy shall be deemed an election, and no waiver by
Bank of any Event of Default on Borrower's part shall be deemed a continuing
waiver. No delay by Bank shall constitute a waiver, election, or acquiescence
by it. No waiver by Bank shall be effective unless made in a written document
signed on behalf of Bank and then shall be effective only in the specific
instance and for the specific purpose for which it was given.

         9.7  DEMAND: PROTEST. Borrower waives demand, protest, notice of
protest, notice of default or dishonor, notice of payment and nonpayment,
notice of any default, notice of intent to accelerate, notice of
acceleration, nonpayment at maturity, release, compromise, settlement,
extension, or renewal of accounts, documents, instruments, chattel paper, and
guarantees at any time held by Bank on which Borrower may in any way be
liable.

                              CONSULTING AGREEMENT


         This Consulting Agreement (this "Agreement") is made and entered into
as of February 1, 2000 (the "Effective Date"), between ObjectSpace, Inc., a
Delaware corporation (the "Company"), and Graham Glass, an individual residing
in the State of Texas (the "Consultant").

                                   BACKGROUND:

         A. The Consultant is the former Chief Technology Officer of the
Company, and has extensive knowledge of the business, operations and affairs
of the Company.

         B. The Company desires to obtain the services of the Consultant and
the Consultant is willing to furnish his personal services upon the terms and
conditions set forth in this agreement.

                                   AGREEMENTS:

         In consideration of the mutual promises set forth in this Agreement,
the parties agree as follows:

         1. CONSULTING SERVICES. The Company agrees to retain the Consultant
as an independent contractor and not as an employee of the Company in an
advisory and consultative capacity during the term of this Agreement (the
"Consulting Period"). During the Consulting Period, the Consultant will
consult with the Company and use his efforts to assist the Company by
performing such tasks as designated by the Company's President, from time to
time. The parties anticipate that these tasks will be similar to those tasks
Consultant performed while employed by the Company. Consultant acknowledges
that he will be provided with updated confidential and proprietary information
and trade secrets of the Company during the course of his performing his
services as a Consultant and after the execution of this Agreement.

         The obligation of the Consultant to perform services for the Company
will not preclude the Consultant from engaging in any business, employment or
occupation not expressly prohibited by SECTION 7 below, and the Company will
schedule the Consultant's performance of his obligations under this Agreement
to accommodate such other business, employment or occupation. The Consultant
agrees not to enter into contracts on behalf of the Company, or bind the
Company to future commitments without the written approval of the President of
the Company.

         2. CONSULTING PERIOD. The Consulting Period will begin on the
Effective Date and will terminate on January 31, 2001 (the "Expiration Date"),
unless otherwise extended or terminated pursuant to the terms of this
Agreement.

         3. COMPENSATION. As compensation for services rendered to the
Company, the Company agrees to pay to the Consultant a retainer of 14,583.33
per month, payable on the fifteenth and last business day of each month during
the term (the "Consulting Payment").

<PAGE>

         4. PRIMARY LOCATION OF CONSULTANT'S PERFORMANCE; OFFICE. The parties
contemplate that the Consultant's performance hereunder will require the
Consultant's presence primarily in Dallas, Texas.

         6. EXPENSES. The Company agrees to pay or reimburse the Consultant
for reasonable expenses incurred or paid by the Consultant, upon presentation
of expense statements or vouchers and such other information as the Company
may reasonably require; PROVIDED that such expenses have been approved, orally
or in writing and in advance, by the Company.

         7. INVENTIONS. The Consultant agrees to disclose promptly, completely
and in writing to the Company any invention, discovery, process, design,
diagram, method, apparatus or improvement, whether patentable or not, whether
implemented or not, which the Consultant develops or discovers individually or
with others during the performance of his services for the Company, or using
or influenced by the Company's time, data, facilities or materials
("Inventions"). The Consultant agrees that all Inventions are the Company's
exclusive property, whether or not patent applications are filed on them.

         The Consultant agrees to assist the Company at any time, during or
after the Consulting Period, at the Company's expense (including payment for
the Consultant's time at the rate set forth in Section 3 above), in the
preparation, execution and delivery of any disclosures, patent applications or
papers required to obtain patents for Inventions, and in connection with any
other proceedings that may be necessary to enforce the Company's rights in
Inventions against others or to vest title to them in the Company.

         The Company and the Consultant acknowledge and agree that any
invention, discovery, process, design, diagram, method, apparatus or
improvement, whether patentable or not, whether implemented or not, that is
developed or discovered by the Consultant independent of the Company, its
agents and employees, and its time, data, facilities or materials, are
expressly excluded from the definition of Inventions, and will be the
exclusive property of the Consultant ("Consultant's Property").

         The Company agrees to document in writing each topic discussed with
the Consultant, and Consultant agrees that such document will be conclusive
evidence of the Company's rights in any Inventions relating to or developed
from those discussions or topics.

         8. COPYRIGHTS. The Consultant agrees that the Company will be the
copyright proprietor in all copyrightable works created or developed by the
Consultant individually or with other pursuant to the Consulting Services.

         The Consultant further agrees, if so requested and at no further
expense to the Company, to execute in writing any acknowledgements or
assignment of copyright ownership of works within this Agreement as may be
necessary for the preservation of the worldwide proprietorship in the Company
of such copyrights.

<PAGE>

         9. PROTECTION OF THE COMPANY'S INTEREST.

                  (a) Non-Compete. During the Consulting Period, the Consultant
         agrees that he will not own or have any interest in, or act as a
         manager, officer, director, executive, consultant, agent or
         representative of, or assist in any way or in any capacity, any
         person, firm, association, partnership, corporation, limited
         liability company, or other entity that (i) manufactures, distribute
         or sells products in competition with the Company's Products (as
         hereinafter defined), anywhere within North America, or (ii) solicit
         business in competition with the Company from (y) any of the
         Company's customers who transacted business with the Company during
         the one year period prior to the Effective Date with whom the
         Consultant or his direct reports had contact while Consultant was
         employed by the Company, or (z) any of the Company's potential
         customers with whom the Consultant or his direct reports had contact
         while Consultant was employed by the Company. As used herein,
         "Company's Products" means the same or similar products or services
         as the Company currently provides, including, but not limited to a
         line of "middleware" products known as "Voyager" and object-oriented
         consulting and training services. The Consultant acknowledges and
         agrees that the Company sells the Company's Products throughout North
         America and , therefore, the geographic scope of the restriction
         contained herein is both reasonable and necessary under the
         circumstances.

                  (b) Non-Solicitation. During the Consulting Period and for a
         one year period thereafter, the Consultant will not directly or
         indirectly, whether for himself or any other person or entity, employ,
         hire, solicit or try to entice away any person who (i) was an employee
         or independent contractor of the Company during Consultant's prior
         employment with the Company, or (ii) was employed by any of the
         Company's customers and with whom the Consultant or his direct reports
         had contact while Consultant was employed by the Company.

                  (c) Confidential Information. The Consultant acknowledges
         that the Company's trade secretes, proprietary information and
         know-how are valuable, special and unique assets of the Company's
         business, access to and knowledge of which are essential to the
         performance of the Consulting Services hereunder. The Consultant
         agrees to keep confidential, except as the President of the Company
         may otherwise consent in writing, and not to disclose, or may any use
         of except for the benefit of the Company, at any time either during
         or after the Consulting Period, any trade secrets, proprietary
         information or know-how of the Company, including, but not limited
         to, that which relates to the Company or the Company's research,
         services, development, processes, designs, formulas, test data,
         purchasing, accounting, customer lists, business plans, marketing
         plans and strategies, pricing strategies, internal operating
         procedures, written materials provided to third parties by agreement,
         implementation techniques of the Company's programs, or other subject
         matter pertaining to any business of the Company or any of its
         clients, customers, consultants, licensees, or affiliates that the
         Consultant may produce, obtain or otherwise acquire during the
         Consulting Period, except as provided herein. The Consultant further
         agrees not to deliver or allow to be delivered trade secrets,
         proprietary information or know-

<PAGE>

         how to third parties without the consent of an authorized
         representative of the President of the Company.

         10. INJUNCTIVE RELIEF. In the event of a breach or threatened breach
by the Consultant of the provisions of SECTION 9 of this Agreement, the
Consultant acknowledges and agrees that such a breach or threatened breach
will cause irreparable injury to the Company for which an adequate remedy is
not available at law. Therefore, the parties hereto agree that the Company
shall be entitled, without the posting of any bond, to an injunction
restraining the Consultant, in whole or in part, from such breach or
threatened breach. Nothing herein shall be construed as prohibiting the
Company from pursuing any other remedies available to the Company for such
breach or threatened breach at law or in equity, including the recovery of
damages from the Consultant. The Consultant acknowledges that the possible
restrictions on his activities which may occur as a result of the performance
of his obligations under SECTION 9 of this Agreement are reasonably required
for the protection of the Company and its investments.

         11. EMPLOYMENT AGREEMENT. The Consultant acknowledges and agrees that
the terms and conditions of this Agreement do not modify or amend the
continuing obligations of the Consultant under that certain Employment
Agreement dated as of December 30, 1998, between the Company and the
Consultant.

         12. PAYMENT DEFAULT; INTEREST. Any past due consulting compensation
shall accrue interest beginning thirty days after such payment becomes past
due at a rate equal to one and one-half percent of such past due amount per
month. Interest shall be calculated on the basis of 30-day months and a
360-day year. In the event the Company fails to pay the consulting fee within
30 days after such fee is due, Consultant may declare to be due all consulting
fees payable during the remainder of the Consulting Period.

                                 FIRST AMENDMENT
                                       TO
                           LOAN AND SECURITY AGREEMENT

         This First Amendment to Loan and Security Agreement (this
"Amendment") is entered into as of March 5, 1998 by and between Silicon Valley
Bank ("Bank") and ObjectSpace, Inc. ("Borrower").


                                    RECITALS

         Borrower and Bank are parties to that certain Loan and Security
Agreement dated as of February 9, 1998 (the "Agreement"). Borrower and Bank
desire to make certain changes to the Agreement, subject to the terms of this
Amendment.

         NOW, THEREFORE, the parties agree as follows:

         1. Bank and Borrower agree that the accounts receivable shown on
Borrower's monthly financial statements, prepared as of the last day of the
calendar month, and delivered to Bank in accordance with the Agreement, shall
not include accrued revenue. Further, the definition of "Quick Assets" is
hereby deleted in its entirety and replaced with the following:

                  "Quick Assets" means, as of any applicable date, the
                  consolidated cash, cash equivalents, accounts receivable and
                  investments with maturities of fewer than ninety (90) days of
                  Borrower determined in accordance with GAAP. Accrued revenue
                  will not be classified as an account receivable for purposes
                  of calculating Quick Assets.

         2. Bank and Borrower agree that the Borrowing Base Certificate and
the aged listings of accounts receivable and accounts payable delivered to
Bank by Borrower in accordance with and pursuant to Section 6.3 of the
Agreement will include, as accounts receivable, that accrued revenue for
services that were performed by Borrower during the previous month and billed
within ten (10) days after the last day of the month in which the services
were performed. Therefore, pursuant to Section 6.3 of the Agreement, if no
Overadvance is outstanding, Borrower shall deliver to Bank the Borrowing Base
Certificate, together with aged listings of accounts receivable and accounts
payable within twenty (20) days after the last day of each month; provided,
however, the cut-off for the calculation of accounts receivable and accounts
payable shall be the tenth (10th) day of the month in which the Borrowing Base
Certificate and aged listing of accounts receivable and accounts payable are
delivered to Bank by Borrower.

         3. Unless otherwise defined, all capitalized terms in this Amendment
shall be as defined in the Agreement. As amended hereby, the Agreement remains
in full force and effect.

         4. Borrower represents and warrants that the Representations and
Warranties contained in the Agreement are true and correct as of the date of
this Amendment.

<PAGE>

         5. This Amendment may be executed in two or more counterparts, each
of which shall be deemed an original, but all of which together shall
constitute one instrument.

         6. As a condition to the effectiveness of this Amendment, Borrower
shall reimburse Bank for the Bank Expenses incurred in connection with this
Amendment.

         IN WITNESS WHEREOF, the undersigned have executed this Amendment as
of the first date above written.
