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

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

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.

                                      II-4

                                   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
Dallas, State of Texas, on the 27th day of April, 2000.
