potential benefits of these efforts would constitute a substantial and
irreparable injury to Employer;

       WHEREAS, Employer has expended and is continuing to expend considerable
time and money recruiting, training, making instruction available to and
compensating its employees, representatives and contractors, and the loss of
their services or potential services would constitute a substantial and

       WHEREAS, Executive acknowledges that the remuneration, receipt of

Agreement, and he understands that he need not continue employment with
Employer and that he has freely chosen to enter into this Agreement;

       WHEREAS, Executive acknowledges that Employer's business involves
customers throughout North America;

       NOW, THEREFORE, in consideration of the mutual covenants and
acknowledgments contained herein, the parties agree as follows:

       The term of this Agreement shall commence on the date hereof and shall
terminate upon the fifth anniversary hereof, unless earlier terminated by the
termination of Executive's employment under Section 2 below; PROVIDED, that
the provisions of Sections 5, 6, 7, 8, 10, 11, 13 and 14 of this Agreement,
shall survive the termination of this Agreement for any reason.

       2.     TERMINATION OF EMPLOYMENT.  Either Employer or Executive may

notice by Executive to Employer if such termination is without Good Reason,
(ii) on eight weeks' prior written notice by Employer to Executive if such
termination is without Cause, or (iii) immediately upon written notice in the
case of a termination for Cause or Good Reason.  In the event that employment
is terminated by Executive for Good Reason or by Employer without Cause,
Employer will pay Executive severance pay of one year's salary at the salary

further obligation to provide any benefits or make any payments (including
Severance Payments) to Executive except to the extent required by law.

       For purposes of this Agreement, "CAUSE" shall mean:

              (i)    any act or acts of dishonesty on the part of Executive
                     resulting in or intended to result, directly or
                     indirectly, in substantial gain or substantial personal
                     enrichment at the expense of Employer;

              (ii)   fraud, misappropriation, embezzlement, or willful and

                     property of Employer or its business;

              (iii)  a good faith determination by a majority of the Board of
                     Directors of Employer that Executive has exhibited a
                     pattern or practice of willful disregard of his duties as
                     an employee of Employer;

              (iv)   the conviction of Executive of a felony;

to make payments specified in the preceding clause (A) above) which breach is
materially adverse to the Executive, including, without limitation, a material

notice thereof is given to Employer by the Executive.

       As used in this Agreement, the term "DISABILITY" shall mean the
circumstance that shall exist if: (i) Executive is deemed disabled pursuant to
the definition of disability under any Employer-sponsored disability insurance

duties under this Agreement, as determined in good faith by Employer, for a
period of 180 consecutive days, or if, in any 12-month period, the Executive
shall have been unable or unwilling or shall have failed to perform
Executive's duties for a period of 270 days, irrespective of whether or not
such days are consecutive.

       3.     COMPENSATION AND BENEFITS.   For all services by the Executive

to termination or amendment at any time.

industriously perform all the duties required of him as Chief Executive
Officer to the reasonable satisfaction of the Board of Directors of Employer

that the amount of such time will be consistent with Employer's reasonable
practice.

       5.     INVENTIONS.  Executive agrees to disclose promptly, completely
and in writing to Employer any invention, discovery, process, design, diagram,
method, apparatus or improvement, whether patentable or not, whether
implemented or not, which Executive develops or discovers individually or with
others during the performance of Executive's duties for Employer or using or
influenced by Employer's time, data, facilities or materials (all hereinafter
called "INVENTIONS"). Executive's obligations under this Section apply
regardless of whether an idea for an Invention occurs to Executive on the job,
at home, or elsewhere.  Executive further agrees that all Inventions are
Employer's exclusive property, whether or not patent applications are filed on
them.

                                     -3-

of any disclosures, patent applications or papers required to obtain patents

employment is terminated, Employer will pay Executive at a reasonable rate.

       6.     REPRESENTATIONS:  Executive agrees not to use ObjectSpace's name

copyright ownership of works within this Agreement as may be necessary for the
preservation of the worldwide proprietorship in Employer of such copyrights.

       8.     PROTECTIONS OF EMPLOYER'S INTERESTS.

              (a)    NON-COMPETE.  During the period that the Executive is
       employed by the Employer and for a period of one year following the
       termination of employment for any reason, the Executive agrees that the
       Executive will not (i) 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
       (a) manufactures, distributes or sells products in competition with the
       Employer's Products, as hereinafter defined, anywhere within North
       America or (b) solicit business in competition with the Employer from
       (y) any customers of the Employer who transacted business with the
       Employer during the one year period prior to such termination with whom
       the Executive or his direct reports had contact or (z) any potential
       customers of the Employer with whom the Executive or his direct reports
       had contact during the one year period prior to such termination.  As
       used herein, the term "PRODUCTS" means the same or similar products or
       services as the Employer currently provides, including, but not limited
       to a line of "middleware" products known as "Voyager" and
       object-oriented consulting and training services.  The Executive
       acknowledges and agrees that the Employer sells its Products throughout
       North America and, therefore, the geographic scope of the restriction
       contained herein is both reasonable and necessary under the
       circumstances.  Notwithstanding anything in this Section 8(a) to the
       contrary, in the event employment is terminated by Employer without
       Cause or by Executive for Good Reason, Executive shall be entitled to
       provide training and consulting services to any Persons other than the
       customers and potential customers identified in clauses (b)(y) and
       (b)(z) of this Section 8(a).

                                     -4-

<PAGE>

              (b)    NON-SOLICITATION.  During Executive's employment with
       Employer and for two years thereafter, Executive 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 (1) was an employee
       or independent contractor of Employer during Executive's employment by
       Employer, or (2) was employed by any customer of Employer and with whom
       Executive had direct contact during Executive's employment with
       Employer.

              (c)    BUSINESS OPPORTUNITY.  Executive agrees that given the
       relationship between the parties, the restrictions in Sections 8(a) and
       8(b) contain reasonable restrictions of time, geographical area, and
       scope of activity and that these restrictions do not impose any greater
       restraint than is necessary to protect the goodwill and other legitimate
       business interests of Employer, including but not limited to the
       personal goodwill developed by Executive with Employer's clients or
       customers and the protection of Employer's trade secrets, proprietary
       information and know-how.  Executive further agrees that the
       restrictions in Sections 8(a) and 8(b) will not prevent him from
       obtaining gainful employment or cause him undue hardship.

              (d)    CONFIDENTIALITY.  Executive acknowledges that Employer's
       trade secrets, proprietary information and know-how are valuable,
       special and unique assets of Employer's business, access to and
       knowledge of which are essential to the performance of Executive's
       duties hereunder. Executive agrees to keep confidential, except as the
       Board of Directors of Employer may otherwise consent in writing, and
       not to disclose, or make any use of except for the benefit of the
       Employer, at any time either during or after his employment, any trade
       secrets, proprietary information or know-how of the Employer, including
       but not limited to that which relates to the Employer or the Employer'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 Employer programs, or other subject matter
       pertaining to any business of the Employer or any of its clients,
       customers, consultants, licensees, or affiliates that Executive may
       produce, obtain or otherwise acquire during his employment, except as
       provided herein. Executive further agrees not to deliver or allow to be
       delivered trade secrets, proprietary information or know-how to third
       parties without the consent of an authorized representative of the
       Board of Directors of Employer.  Executive further agrees that he will
       not use or disclose to Employer confidential information belonging to
       his former employers.

              (e)    DISCLOSURE.  Executive will make the terms and conditions
       of this Agreement known to any business, entity or person engaged in
       activities competitive with Employer's business with which he becomes
       associated.  Employer will have the right to make the terms of this
       confidentiality agreement known to third persons.

              (f)    EMPLOYER DOCUMENTS.  At the time of Executive's
       termination or upon demand by the Board of Directors of Employer
       (whichever is sooner), Executive will promptly turn over to Employer
       all files, documents, business records, lists of customers and
       potential customers, promotional materials, internal operating reports,
       names and addresses of executives and potential executives, customer
       strategy information,

                                     -5-

<PAGE>

       employment and payroll records, marketing information, manuals, billing
       reports, pricing information and strategies, management methods and
       systems, contracts with customers, subcontractors and others,
       correspondence, resumes of existing and potential executives, customer
       bids and proposals, books and records, and any other records,
       documents, writings of any kind whatsoever, and all assets of any kind
       whatsoever that belong to Employer.  Further, Executive will not copy
       or record in any manner whatsoever the information contained in the
       foregoing materials, and Executive will turn over to Employer any
       copies or recordings of any kind whatsoever containing information
       derived directly or indirectly from such materials.

              (g)    ENFORCEMENT. The parties agree that if there is a breach
       or threatened breach by Executive of any of the provisions of this
       Section 8, Employer will be entitled to injunctive relief restraining
       Executive, as any breach or threatened breach would cause irreparable
       injury to Employer for which there would be no adequate remedy at law.
       Nothing herein prohibits Employer from pursuing other remedies
       available for any breach or threatened breach, including the recovery
       of damages from Executive. Should any provision of this Section 8 be
       held unreasonably broad in its restrictions as to time, geographical
       area, or scope of activity, the provision will be limited as necessary
       to render it reasonable.

              (h)    CONSTRUCTION.  The covenants of Executive contained in
       this Section 8 will be construed as an agreement independent of any
       other provision of this Agreement, and the existence of any claim or
       cause of action of Executive against Employer, whether predicated on
       this Agreement or otherwise, will not constitute a defense to the
       enforcement by Employer of said covenants.

       9.     COMMUNICATIONS:  All communications to Employer pursuant to this
Agreement must be in writing and addressed to:

              ObjectSpace, Inc.

       arise between the Employer and Executive during or following Executive's
       employment with the Employer, and that those differences may or may not
       be related to Executive's employment with the Employer.  Executive
       understands and agrees that the Employer is engaged in transactions
       involving interstate commerce and that Executive's employment with
       Employer involves such commerce.  Executive understands and agrees that
       by agreeing to arbitration hereunder, the Executive anticipates gaining
       the benefits of speedy, impartial dispute resolution of any Claim (as

<PAGE>

              (b)    AGREEMENT TO ARBITRATE.  In the event there is any dispute,
       claim, or controversy, whether or not arising out of Executive's
       employment, its termination, or this Agreement and regardless of the kind
       or type of dispute, claim or controversy (excluding claims for workers'
       compensation, unemployment compensation benefits and claims by the
       Employer for injunctive and/or other equitable relief) that the Employer
       may have against Executive or that Executive may have against the

       affiliates, representatives, or agents in their capacity as such or
       otherwise (all such disputes, claims or controversies being collectively
       referred to as "CLAIMS"), the Executive and the Employer agree to submit

       provisions of the Federal Arbitration Act, upon a request submitted in
       writing to the Board of Directors of Employer within two years of the
       date when the aggrieved party has knowledge of the event giving rise to
       the claim, or within two years of the termination of employment,
       whichever occurs first.  Except as provided in Sections 13(c) and 13(d)
       hereof, arbitration shall be the sole and exclusive remedy for all Claims
       covered by this Agreement, and any failure to request arbitration timely
       shall constitute a waiver of all rights to raise any Claims in any forum,
       even if there is a federal or state statute of limitations that would
       have given more time to pursue the Claim.  The limitations period set
       forth in this paragraph shall not be subject to tolling, equitable or
       otherwise.

              (c)    CLAIMS COVERED.  The Claims covered by this Agreement

       limited to, race, sex, sexual harassment, sexual orientation, religion,

       medical condition, handicap or disability); claims for benefits (except
       where an employee benefit or retirement plan specifies that its claims
       procedure shall culminate in an arbitration procedure different from this
       one); and claims for violation of any federal, state, or other
       governmental law, statute, regulation, or ordinance, except claims
       excluded in Section 13(d).  Executive understands that this Section 13
       covers Claims not only against the Employer, but all other potential
       defendants, including but not limited to co-employees, managers,
       supervisors, directors, officers, stockholders, joint employers,
       representatives, agents, and parent, subsidiary, affiliated and successor
       companies.  Further, Executive understands that Executive is not waiving
       Executive's right to pursue a charge at any time with the National Labor
       Relations Board or any other federal, state or city agency.

              (d)    CLAIMS NOT COVERED.  Claims Executive may have for workers'

<PAGE>

       Executive understands and agrees that the Employer may seek and obtain
       relief from a court of competent jurisdiction.

              (e)    PROCEDURE.  All Claims will be resolved by a single
       arbitrator in Dallas, Texas in accordance with the National Rules for the
       Resolution of Employment Disputes of the American Arbitration Association
       (the "AAA"), as amended, modified or revised.  The arbitrator shall apply
       federal and/or Texas substantive law, as appropriate to the particular
       claims presented.  Judgment upon the award rendered by the arbitrator may
       be entered in any court having jurisdiction.  To the extent this
       Section 13 and the rules of the AAA conflict, this Section shall prevail.

              (f)    THE ARBITRATOR'S AUTHORITY.  The arbitrator shall only have
       those powers authorized by statute or enumerated below:

              (i)    Rule on motions regarding the pleadings and discovery;

              (ii)   Issue protective orders on the motion of any party or third
                     party witness.  Such protective orders may include, but are
                     not limited to, sealing the record of the arbitration, in
                     whole or in part (including discovery proceedings and
                     motions, transcripts and the decision and award), to
                     protect the privacy or other constitutional or statutory
                     rights of parties and/or witnesses;

              (iii)  Determine only the Claim submitted to the arbitrator.  The
                     Claim shall be identified in any request for arbitration,
                     any counterclaim(s), and the answer(s) thereto.  Any Claim
                     not identified in those pleadings is outside the scope of
                     the arbitrator's jurisdiction and any award invoking such
                     Claims is subject to a motion to vacate; PROVIDED, HOWEVER,
                     that the arbitrator shall have exclusive authority to
                     resolve any Claim relating to the validity, interpretation,
                     application, and enforcement of this Section 13; and

              (iv)   The arbitrator shall only be authorized to exercise powers
                     specifically enumerated by this Agreement and to decide the
                     Claim in accordance with governing principles of law and
                     equity.  The arbitrator shall not have any authority to
                     modify the powers granted to the arbitrator by the terms of
                     this Agreement.  The arbitrator also shall not have the
                     authority to modify a party's responsibility for fees and
                     costs as set forth below, except as required by law.

              (g)    COSTS OF ARBITRATION.  If a party chooses to be represented
       by an attorney (or other representative) during the arbitration, that
       party shall be responsible for its own attorneys' fees, except as
       provided by law.  Each party shall be responsible for one-half the cost
       of the court reporters' fees, the AAA's filing fee, the arbitrator's fee,
       the cost of the arbitrator's transcript of the hearing and any costs
       associated with the facilities for the arbitration (E.G., the hearing
       room).  Each party shall be responsible for all costs associated with
       discovery which that party initiates (E.G., depositions), except

                                       -9-
<PAGE>

       that a party or third party witness being deposed shall be responsible
       for the cost of a copy of the transcript if he chooses to order a copy.

       14.    GENERAL PROVISIONS

              (a)    ENTIRE AGREEMENT.  This Agreement supersedes, replaces and
       merges any and all prior and contemporaneous understandings,
       representations, agreements and discussions relating to the same or
       similar subject matter as that of this Agreement and constitutes the
       entire agreement between Executive and Employer about the subject matter
       of this Agreement.

              (b)    NO CONFLICT.  Executive represents and warrants that he is
       not under any legal or contractual obligation that would conflict with
       the obligations and duties he is undertaking herein, and that his
       execution of this Agreement will not breach any agreement to which he is
       a party.

              (c)    SEVERABILITY.  If any provision of this Agreement is held
       unenforceable under present or future laws, the provision will be
       severable, and this Agreement will be construed and enforced as if the
       unenforceable provision never comprised a part of it.  Furthermore, in
       lieu of the unenforceable provision, there will be added automatically a
       provision as similar in its terms to the unenforceable provision as may
       be enforceable.

              (d)    REMEDIES.  If any violation of the covenants contained
       herein occurs, as determined by any court of competent jurisdiction,
       Employer will be authorized and entitled to obtain preliminary and
       permanent injunctive relief as well as an equitable accounting of any and
       all profits or benefits arising out of such violation, which rights and
       remedies will be cumulative and in addition to any other rights or
       remedies to which Employer may be entitled, including the right to
       damages directly or indirectly sustained by Employer.  Except as provided
       in Section 13, Executive further agrees to pay the reasonable attorneys'
       fees, court costs and litigation expenses incurred by Employer in
       successfully enforcing any of the provisions of this Agreement.

              In the event of the violation of any of the covenants contained
       herein, the period, if any, therein will abate during the time of
       violation thereof and that portion remaining at the time of commencement
       of any violation will not begin to run until such violation has been
       fully and finally cured.

              (e)    CAPTIONS.  The captions contained herein are solely for the
       convenience of the parties and will not be deemed to govern the meaning
       or intent of any of the provisions of this Agreement.

              (f)    GENDER.  Whenever the male gender is used in this
       Agreement, it is applicable to both male, female and neuter, singular and
       plural.

              (g)    ASSIGNMENT.  The rights and obligations of Employer
       hereunder will inure to the benefit of and be binding upon any successor
       or assign of Employer.  This

                                      -10-
<PAGE>

       Agreement is personal to Executive and shall not be assigned by him.
       Any attempted assignment by Executive in violation of this Agreement
       shall be void.

              (h)    WAIVER.  The waiver or non-enforcement by Employer or any
       breach of any provision of this Agreement by Executive will not be a
       waiver of any subsequent breach by Executive.  No waiver will be legally
       operative unless in writing and signed by an authorized agent of
       Employer.

              (i)    GOVERNING LAW.  This Agreement will be construed according
       to the laws of Texas, without regard to its conflict of law principles,
       and venue in any legal proceeding will be in Dallas County, Texas.

              (j)    AMENDMENT.  The parties may amend this Agreement only by a
       signed, written agreement.

                                      TO
                              EMPLOYMENT AGREEMENT

        This Amendment to Employment Agreement is entered into as of March
28, 2000 (this "Amendment"), between ObjectSpace, Inc., a Delaware
corporation (the "Company"), and Mr. David Norris, an individual residing in
the State of Texas ("Mr. Norris") and amends that certain Employment
Agreement between the parties dated as of December 30, 1998 (the "Agreement")

        In consideration of the mutual promises contained in this Amendment,
the parties agree as follows:

        1. As consideration for this Amendment, the Company agrees to, and
           will provide updated confidential and proprietary information and
           trade secrets to Mr. Norris during his term of employment and after
           the execution of this Amendment

        2. Section 8(a) of the Agreement is hereby amended in its entirety to
           read as follows:

           (a) Non-Compete.  During the period that the Executive is employed
               by the Employer and for a period of one year following the
               termination of employment for any reason, the Executive agrees
               that the Executive will not (i) 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
               (a) manufactures, distributes or sells products in competition
               with the Employer's Products (as hereinafter defined),
               anywhere within North America, or (b) solicit business in
               competition with the Employer from (y) any of the Employer's
               customers who transacted business with the Employer during the
               one year period prior to such termination with whom the
               Executive or his direct reports had contact, or (z) any of the
               Employer's potential customers with whom the Employer or his
               direct reports had contact during the one year period prior to
               such termination.  As used herein, "Products" means the same
               or similar products or services as the Employer provides
               during Executive's term of employment, including, but not
               limited to a line of "middleware" products known as "Voyager,"
               business to business integration products known as
               "OpenBusiness," and object-oriented consulting and training
               services.  The Executive acknowledges and agrees that the
               Employer sells the Products throughout North America and,

               therefore, the geographic scope of the restriction contained
               herein is both reasonable and necessary under the

               to the contrary, in the event employment is terminated by
               Employer without Cause or by Executive for Good Reason,
               Executive shall be entitled to provide training and consulting
               services to any Persons other than customers and potential
               customers identified in clause (b)(y) and (b)(z) of this
               Section 8(a).

        3. Except as set forth herein, all other terms and conditions of the
Agreement remain in full force and effect, and are hereby ratified.
