         a.       Purchase for Own Account. The Purchaser is purchasing the
Shares for the Purchaser's own account and not with a present view towards the
distribution thereof. The Purchaser understands and acknowledges that the
Purchaser must bear the economic risk of this investment indefinitely, unless
the Shares are registered pursuant to the Securities Act of 1933, as amended
(the "Securities Act"), and any applicable state securities or blue sky laws or
an exemption from such registration is available, and that the Company has no
present intention of registering any such Shares other than as contemplated by
Section 5(k). Notwithstanding anything in this Section 3(a) to the contrary, by
making the foregoing representation, the Purchaser does not agree to hold the

subsidiaries and materials relating to the offer and sale of the Shares which
have been requested by the Purchaser. The Purchaser has been afforded the
opportunity to ask questions of the Company and has received satisfactory
answers to any such inquiries. Neither such inquiries nor any other due
diligence investigation conducted by the Purchaser or its counsel or any of its
representatives shall modify, amend or affect the Purchaser's right to rely on
the Company's representations and warranties contained in Section 4 below.

         c.       Governmental Review. The Purchaser understands that no United
States federal or state agency or any other government or governmental agency
has passed upon or made any recommendation or endorsement of the Shares.

         d.       Authorization; Enforcement. The Purchaser has the requisite
power and authority to enter into and perform its obligations under this
Agreement and to purchase the Shares in accordance with the terms hereof. This
Agreement has been duly and validly authorized, executed and delivered on
behalf of the Purchaser and is a valid and binding agreement of the Purchaser
enforceable against the Purchaser in accordance with its terms, subject to
applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent
transfer and other laws affecting creditors' rights and remedies generally and
to general principles of equity (regardless of whether enforcement is sought in
a proceeding at law or in equity).

         e.       Transfer or Resale. The Purchaser understands that (i) except
as provided in Section 5(k), the Shares have not been and are not being
registered under the Securities Act or any state securities laws, and may not
be transferred unless (a) subsequently registered thereunder, (b) the Purchaser
shall have delivered to the Company an opinion of counsel reasonably acceptable
to the Company (which opinion shall be in form, substance and scope customary
for opinions of counsel in comparable transactions) to the effect that the
Shares to be sold or transferred may be sold or transferred under an exemption
from such registration, or (c) sold under Rule 144 promulgated under the
Securities Act (or a successor rule); and (ii) neither the Company nor any
other person is under any obligation to register such Shares under the
Securities Act or any state securities laws or to comply with the terms and
conditions of any exemption thereunder, in each case, other than pursuant to
the registration rights in Section 5(k). Notwithstanding the foregoing, no such
registration statement or opinion of counsel shall be necessary for a transfer
by the Purchaser to its stockholders in accordance with their interest in the
corporation.

         f.       Legends. The Purchaser understands that the Shares and, until
such time as the Shares have been registered under the Securities Act as
contemplated by the registration rights in Section 5(k) or otherwise may be
sold by the Purchaser under Rule 144, the certificates for the Shares will bear
a restrictive legend in substantially the following form:

                                       3
<PAGE>   4

                  The securities represented by this certificate have not been
                  registered under the Securities Act of 1933, as amended, or
                  the securities laws of any state of the United States. The
                  securities represented hereby may not be offered or sold in
                  the absence of an effective registration statement for the
                  securities under applicable securities laws unless offered,
                  sold or transferred under an available exemption from the
                  registration requirements of those laws.

         The legend set forth above shall be removed and the Company shall
issue a certificate without such legend to the holder of any Shares upon which
it is stamped, if, (a) the sale of any such Shares is registered under the
Securities Act, (b) such holder provides the Company with an opinion of
counsel, in form and substance customary for opinions of counsel in comparable
transactions, to the effect that a public sale or transfer of any such Shares
may be made without registration under the Securities Act or (c) such holder
provides the Company with reasonable assurances that any such Shares can be
sold under Rule 144. The Purchaser agrees to sell all Shares, including those
represented by a certificate(s) from which the legend has been removed,
pursuant to an effective registration statement or under an exemption from the
registration requirements of the Securities Act. The legend shall be removed
when such Shares may be sold pursuant to an effective registration statement or
sold under Rule 144(k).

         g.       Accredited Investor Status. The Purchaser is an "accredited
investor" as that term is defined in Rule 501(a) of Regulation D ("Regulation
D") promulgated by the United States Securities and Exchange Commission (the
"SEC") under the Securities Act. The Purchaser is not registered as a broker or
dealer under Section 15(a) of the Securities Exchange Act of 1934, as amended,
or a member of the National Association of Securities Dealers.

         h.       Company Reliance. The Purchaser understands that the Shares
are being offered and sold to it in reliance on an exemption from the
registration requirements of United States federal and state securities laws
and that the Company is relying upon the truth and accuracy of, and the
Purchaser's compliance with, the representations, warranties, agreements,
acknowledgments, and understandings of the Purchaser set forth herein in order
to determine the availability of such exemptions and the eligibility of the
Purchaser to acquire the Shares.

4.       REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

         The Company represents and warrants to the Purchaser as follows:

         a.       Organization and Qualification. The Company is a corporation,
and each of its subsidiaries is an entity, duly organized and existing under
the laws of the jurisdiction in which it is organized, and has the requisite
corporate power to own its properties and to carry on its business as now being
conducted. The Company and each of its subsidiaries is duly qualified as a
foreign entity to do business and is in good standing in every jurisdiction in
which the nature of the business conducted by it makes such qualification
necessary and where the failure so to qualify would have a Material Adverse
Effect. The SEC Documents (as hereinafter defined) set

                                       4
<PAGE>   5

forth the name of each of the Company's subsidiaries and its jurisdiction of
organization. Each of the Company's subsidiaries are wholly-owned.

         b.       Authorization; Enforcement. (i) The Company has the requisite
corporate power and authority to enter into and perform its obligations under
this Agreement and to issue and sell the Shares in accordance with the terms
hereof; (ii) the execution, delivery and performance of this Agreement by the
Company and the consummation by it of the transactions contemplated hereby
(including, without limitation, the issuance and sale of the Shares) have been
duly authorized by the Company's Board of Directors and no further consent or
authorization of the Company, its Board of Directors or its stockholders is
required; (iii) this Agreement has been duly executed and delivered by the
Company; and (iv) this Agreement constitutes the valid and binding obligation
of the Company enforceable against the Company in accordance with their
respective terms, subject to applicable bankruptcy, insolvency, reorganization,
moratorium, fraudulent transfer and other laws affecting creditors' rights and
remedies generally and to general principles of equity (regardless of whether
enforcement is sought in a proceeding at law or in equity).

         c.       Capitalization. As of the date hereof, the authorized capital
stock of the Company consists of 25,000,000 shares, consisting of two classes:
22,500,000 shares of Common Stock and 2,500,000 shares of preferred stock, par
value $.01 per Share (the "Preferred Stock"). According to a certificate from
the Company's transfer agent dated November 12, 2000, an aggregate of
11,887,307 shares of the Company's Common Stock were issued and outstanding as
of the date of such transfer agent certificate. No shares of the Company's
Preferred Stock are outstanding as of the date hereof. As of the date hereof,
there is an aggregate of 4,630,599 shares of the Company's Common Stock
reserved for issuance under the Company's stock option plans and employee stock
purchase plan. All of such outstanding shares of the Company's capital stock
have been, or upon issuance will be, validly issued, fully paid and
nonassessable. Except as set forth in this Section 4(c) or on the disclosure
schedule (the "Schedule") referencing this Section 4(c), no shares of capital
stock of the Company (including the Shares) or any of its subsidiaries are
subject to preemptive rights or any other similar rights of the stockholders of
the Company or any liens or encumbrances created or incurred by the Company.
Except for the Shares and as disclosed in this Section 4(c) or Schedule 4(c),
as of the date of this Agreement, (i) there are no outstanding options,
warrants, scrip, rights to subscribe to, calls or commitments of any character
whatsoever relating to, or securities or rights convertible into or exercisable
or exchangeable for, any shares of capital stock of the Company or any of its
subsidiaries, or arrangements by which the Company or any of its subsidiaries
is or may become bound to issue additional shares of capital stock of the
Company or such subsidiaries, and (ii) there are no agreements or arrangements
under which the Company or any of its subsidiaries is obligated to register the
sale of any of its or their securities under the Securities Act (except as
provided in Section 1.04(d) and 1.09 of the Purchase Agreement and the
Registration Rights Agreement, dated February 18, 2000 (the "Registration
Rights Agreement"), among the Company, the Purchaser and the other investors
identified therein). Except as set forth on Schedule 4(c), there are no
securities or instruments containing price-based antidilution or similar
provisions that may be triggered by the issuance of the Shares in accordance
with the terms of this Agreement or the Registration Rights Agreement and the
holders of the securities and instruments listed on such Schedule 4(c) have
waived any rights they may have under any such antidilution or similar

                                       5
<PAGE>   6

provisions in connection with the issuance of the Shares in accordance with the
terms of this Agreement or the Registration Rights Agreement. The Company has
made available to the Purchaser and counsel for the Purchaser true and correct
copies of the Company's Certificate of Incorporation as in effect on the date
hereof ("Certificate of Incorporation"), the Company's By-laws as in effect on
the date hereof (the "By-laws") and all other instruments and agreements
governing securities convertible into or exercisable or exchangeable for
capital stock of the Company, except for stock options granted under any
employee benefit plan or director stock option plan of the Company.

         d.       Issuance of Shares. The Shares are duly authorized and when
issued and paid for in accordance with the terms hereof, will be validly
issued, fully paid and non-assessable, and free from all taxes, liens, claims
and encumbrances, and will not be subject to preemptive rights or other similar
rights of stockholders of the Company and will not impose personal liability
upon the holder thereof.

         e.       No Conflicts. The execution, delivery and performance of this
Agreement by the Company, and the consummation by the Company of the
transactions contemplated hereby and thereby (including, without limitation,
the issuance and sale of the Shares) will not (i) conflict with or result in a
violation of the Certificate of Incorporation or By-laws or (ii) conflict with,
or constitute a default (or an event which, with notice or lapse of time or
both, would become a default) under, or give to others any rights of
termination, amendment, acceleration or cancellation of any agreement,
indenture or instrument to which the Company or any of its subsidiaries is a
party, or result in a violation of any law, rule, regulation, order, judgment
or decree (including United States federal and state securities laws and
regulations and AMEX regulations) applicable to the Company or any of its
subsidiaries or by which any property or asset of the Company or any of its
subsidiaries is bound or affected (except, with respect to clause (ii), for
such conflicts, defaults, terminations, amendments, accelerations,
cancellations and violations as would not, individually or in the aggregate,
have a Material Adverse Effect). Neither the Company nor any of its
subsidiaries is in violation of its Certificate of Incorporation, By-laws and
other organizational documents and neither the Company nor any of its
subsidiaries is in default (and no event has occurred which, with notice or
lapse of time or both, would put the Company or any of its subsidiaries in
default) under, nor has there occurred any event giving others (with notice or
lapse of time or both) any rights of termination, amendment, acceleration or
cancellation of, any agreement, indenture or instrument to which the Company or
any of its subsidiaries is a party, except for actual or possible violations,
defaults or rights as would not, individually or in the aggregate, have a
Material Adverse Effect. The businesses of the Company and its subsidiaries are
not being conducted in violation of any law, ordinance or regulation of any
governmental entity, except for actual or possible violations, if any, the
sanctions for which either individually or in the aggregate would not have a
Material Adverse Effect. Except as specifically contemplated by this Agreement
and as required under the Securities Act and any applicable state securities
laws, the Company is not required to obtain any consent, approval,
authorization or order of, or make any filing or registration with, any court
or governmental agency or any regulatory or self regulatory agency in order for
it to execute, deliver or perform any of its obligations under this Agreement
(including, without limitation, the issuance and sale of the Shares as provided
hereby) in accordance with the terms hereof. The Company is not in violation of
the listing requirements of the AMEX and does not reasonably anticipate that
the

                                       6
<PAGE>   7

Common Stock will be delisted by AMEX in the foreseeable future based on its
rules (and interpretations thereof) as currently in effect.

         f.       SEC Documents; Financial Statements. Except for the failure
to timely file a required report on Form 8-K in connection with the acquisition
of Prescient Technologies, Inc., since January 1998, the Company has timely
filed all reports, schedules, forms, statements and other documents required to
be filed by it with the SEC pursuant to the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), and has filed all registration statements and
other documents required to be filed by it with the SEC pursuant to the
Securities Act (all of the foregoing filed prior to the date hereof, and all
exhibits included therein and financial statements and schedules thereto and
documents incorporated by reference therein, being hereinafter referred to
herein as the "SEC Documents"). The Company has made available to the Purchaser
and to counsel for the Purchaser true and complete copies of the SEC Documents
not filed on EDGAR and reasonably requested by Purchaser, except for the
exhibits and schedules thereto and the documents incorporated therein by
reference. As of their respective dates, the SEC Documents complied in all
material respects with the requirements of the Exchange Act or the Securities
Act, as the case may be, and the rules and regulations of the SEC promulgated
thereunder applicable to the SEC Documents, and none of the SEC Documents, at
the time they were filed with the SEC, contained any untrue statement of a
material fact or omitted to state a material fact required to be stated therein
or necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading. Any statements made
in any such SEC Documents that are or were required to be updated or amended
under applicable law have been so updated or amended. As of their respective
dates, the financial statements of the Company included in the SEC Documents
complied in all material respects with applicable accounting requirements and
the published rules and regulations of the SEC applicable with respect thereto.
Such financial statements have been prepared in accordance with United States
generally accepted accounting principles, consistently applied, during the
periods involved (except (i) as may be otherwise indicated in such financial
statements or the notes thereto, or (ii) in the case of unaudited interim
statements, to the extent they may not include footnotes or may be condensed or
summary statements) and fairly present in all material respects the
consolidated financial position of the Company and its subsidiaries as of the
dates thereof and the results of their operations and cash flows for the
periods then ended (subject, in the case of unaudited statements, to normal and
recurring year-end audit adjustments). Except as set forth in the SEC
Documents, the Company has no liabilities, contingent or otherwise, other than
(i) liabilities incurred in the ordinary course of business subsequent to the
date of such SEC Documents and (ii) obligations under contracts and commitments
incurred in the ordinary course of business and not required under generally
accepted accounting principles to be reflected in such SEC Documents, which
liabilities and obligations referred to in clauses (i) and (ii) of this
sentence would not individually or in the aggregate, have a Material Adverse
Effect.

         g.       Absence of Certain Changes. Except as disclosed in the SEC
Documents, since March 31, 2000, there has been no change or development which
individually or in the aggregate has had or could have a Material Adverse
Effect.

         h.       Absence of Litigation. Except as disclosed in the SEC
Documents and set forth on Schedule 4(h), there is no action, suit, proceeding,
inquiry or investigation before or by any

                                       7
<PAGE>   8

court, public board, government agency, self-regulatory organization or body
pending or, or to the knowledge of the Company, threatened against or affecting
the Company, or any of its subsidiaries, or any of their directors or officers
in their capacities as such, except as would not have a Material Adverse
Effect.

         i.       Intellectual Property. The Company and each of its
subsidiaries owns or is licensed to use all patents, patent applications,
trademarks, trademark applications, trade names, service marks, copyrights,
copyright applications, licenses, permits, know-how (including trade secrets
and other unpatented and/or unpatentable proprietary or confidential
information, systems or procedures) and other similar rights and proprietary
knowledge (collectively, "Intangibles") necessary for the conduct of its
business as now being conducted and as proposed to be conducted. Neither the
Company nor any of its subsidiaries is infringing or in conflict with any other
person with respect to any Intangibles. Neither the Company nor any of its
subsidiaries has received written notice that it is infringing upon third party
Intangibles. Neither the Company nor any of its subsidiaries has entered into
any consent, indemnification, forbearance to sue or settlement agreements with
respect to the validity of the Company's or such subsidiary's ownership or
right to use its Intangibles and, to the knowledge of the Company, there is no
basis for any such claim to be successful. The Intangibles are valid and
enforceable, and no registration relating thereto has lapsed, expired or been
abandoned or canceled or is the subject of cancellation or other adversarial
proceedings, and all applications therefor are pending and in good standing.
The Company has complied, in all material respects, with its contractual
obligations relating to the protection of the Intangibles used pursuant to
licenses. To the Company's knowledge, no person is infringing on or violating
the Intangibles owned or used by the Company.

         j.       Agreements. Except for the transactions contemplated by the
Purchase Agreement and except as filed as Exhibits to the SEC Documents or as
set forth in Schedule 4(j), there are no agreements, understandings,
instruments, contracts, proposed transactions, judgments, orders, writs or
decrees to which the Company or any of its subsidiaries is a party or by which
it is bound that may involve (i) obligations (contingent or otherwise) of, or
payments to, the Company in excess of $250,000 (other than licenses pursuant to
license agreements entered into in the ordinary course of the Company's
business) or (ii) the license of any patent, copyright, trade secret or other
proprietary right to or from the Company (other than licenses pursuant to
license agreements entered into in the ordinary course of the Company's
business), or (iii) provisions restricting or affecting the development,
manufacture or distribution of the Company's or its subsidiaries' products or
services, or (iv) indemnification by the Company or any subsidiary with respect
to infringements of proprietary rights (other than indemnification obligations
arising from purchase or sale agreements entered into in the ordinary course of
business) or (v) transactions between the Company and any of the Company's or
its subsidiaries' officers, directors, affiliates, or any affiliates thereof
(other than pursuant to employment agreements or stock or benefit plans), or
(vi) employment of the Company's officers or (vii) incurrence of any
indebtedness for money borrowed or any other liabilities (other than with
respect to dividend obligations, distributions, indebtedness and other
obligations incurred in the ordinary course of business or as disclosed in the
SEC Documents) individually in excess of $250,000 or, in the case of
indebtedness and/or liabilities individually less than $250,000, in excess of
$500,000 in the aggregate, or (viii) the making of any loans or advances to any
person,

                                       8
<PAGE>   9

other than ordinary advances for travel expenses, or (ix) the sale, exchange or
other disposition of any of its assets or rights, other than licenses in the
ordinary course of business.

         k.       Foreign Corrupt Practices. Neither the Company, its
subsidiaries, or any director, officer, agent, employee or other person acting
on behalf of the Company or any of its subsidiaries has, in the course of such
person's actions for, or on behalf of, the Company, or any of its subsidiaries,
used any corporate funds for any unlawful contribution, gift, entertainment or
other unlawful expenses relating to political activity; made any direct or
indirect unlawful payment to any foreign or domestic government official or
employee from corporate funds; violated or is in violation of any provision of
the United States Foreign Corrupt Practices Act of 1977; or made any bribe,
rebate, payoff, influence payment, kickback or other unlawful payment to any
foreign or domestic government official or employee.

         l.       Environment. Except as disclosed in the SEC Documents (i)
there is no environmental liability, nor, to the knowledge of the Company,
factors likely to give rise to any environmental liability, affecting any of
the properties of the Company or any of its subsidiaries that, individually or
in the aggregate, would have a Material Adverse Effect and (ii) neither the
Company nor any of the subsidiaries has violated any environmental law
applicable to it now or previously in effect, other than such violations or
infringements that, individually or in the aggregate, have not had and will not
have a Material Adverse Effect.

         m.       Title. The Company does not own any real property. Any real
property and facilities held under lease by the Company or any of its
subsidiaries are held by the Company or such subsidiary under valid, subsisting
and enforceable leases with such exceptions which have not had and will not
have a Material Adverse Effect.

         n.       Insurance. The Company and its subsidiaries maintain such
insurance relating to their business, operations, assets, key-employees and
officers and directors as is appropriate to their business, assets and
operations, in such amounts and against such risks as are customarily carried
and insured against by owners of comparable businesses, assets and operations,
and such insurance coverages will be continued in full force and effect to and
including the Closing Date other than those insurance coverages in respect of
which the failure to continue in full force and effect could not reasonably be
expected to have a Material Adverse Effect.

         o.       Disclosure. All information relating to or concerning the
Company and its subsidiaries set forth in this Agreement or provided to the
Purchaser in writing in connection with the transactions contemplated hereby is
true and correct in all material respects and the Company has not omitted to
state any material fact necessary in order to make the statements made herein
or therein, in light of the circumstances under which they were made, not
misleading; provided, however, that this representation and warranty shall not
apply to any information contained within any of the foregoing related to
future events, or the projected future financial performance of the Company,
including any financial projections, or descriptions of potential strategic or

                  Party ("Licensee") to whom the other Party ("Licensor") has
                  granted a license under these sections, is allowed to make
                  Derivative Works from the Software so licensed to Licensee.
                  The Parties therefore agree as follows with respect to any
                  such Derivative Works made by Licensee according to the
                  provision of the corresponding license:

         6.1      Ownership of Derivative Works. The Parties agree that all
                  right, title and interest in and to all or part of the
                  Derivative Works made by Licensee pursuant to the licenses
                  granted in the Agreement shall be owned exclusively by
                  Licensor. Licensee understands and agrees that such Derivative
                  Works made by Licensee, as well as any portion thereof, shall
                  be the sole property of Licensor from date of creation and, to
                  the extent permitted by law, shall be considered as works made
                  for hire under the copyright laws of the United States of
                  America. To the extent an assignment is necessary and that
                  this assignment cannot be made at present, Licensee agrees to
                  assign to Licensor all of its right, title and interest in and
                  to these Derivative Works, and any part thereof, and in and to
                  all copyrights, patents and other proprietary rights Licensee
                  may have in such Derivative Works.

                           The Parties however agree that the creator of a
                           Derivative Work shall remain the owner of such
                           Derivative Work should such Derivative Work be
                           Software (i) developed by or for licensee and using
                           all or part of the licensed Software as a component
                           of an application (i.e. embedded or included in whole
                           or in part in such other Software), and (ii) as long
                           as such Software contains new functionality,
                           significant value added, or creates a new function
                           that is packaged as a standalone product and which
                           user interface is different from existing Software.
                           The Parties also agree that application of an
                           alternative interface technology if this interface is
                           not combined with other significant application level
                           functionalities shall not be considered as having
                           significant added value.

         6.2      Delivery Obligations of the Parties.

                  (i)      At the end of each quarter, in the event that either
                           Party has made any Derivative Work, such Party shall
                           deliver to Licensor one copy of the Source Code of
                           such Derivative Work, in a sealed and dated envelope,
                           in the form of a CD-ROM, or other appropriate media.

                  (ii)     Such items shall be sent to Licensor, as applicable,
                           by international registered mail to the following
                           address:

                           or may be delivered to either Party by e-mail
                           transmission if agreed to in advance by the receiving
                           Party.

                           The Parties agree to make their best reasonable
                           commercial efforts to comply with the above process
                           which aims to facilitate the tracing and evidencing
                           of the Derivative Works. Should any Party miss some
                           delivery with that respect, it will make its best
                           reasonable commercial efforts to do it as soon as
                           possible; in any case, both parties recognize that
                           should any of them not deliver Derivative Work under
                           this process, the other Party will keep all its
                           rights and actions to request the transfer of
                           ownership to any work that such other Party deems a
                           Derivative Work under this Agreement.

         6.2      Know-How. The Parties hereby acknowledge and agree that any
                  and all rights to Know-How developed or shared under this
                  Agreement by either Party shall be jointly owned by the
                  Parties and may be used by either party in the operation of
                  their respective business during and following termination of
                  this Agreement.

7.       MAINTENANCE AND SUPPORT

                  PlanetCAD, as the case may be) will provide the Licensee with
                  four years maintenance and support as described in the

                  (b) except if PlanetCAD provides twelve month advance notice
                  of discontinuation of WBM Software.

                  of Control of PlanetCAD to the benefit of a Competitor of
                  Dassault Systemes, Dassault Systemes will not be required to
                  continue providing maintenance or support services, as set
                  forth in Schedule B, for the Translator and/or CBD Software.

                           as to unreasonably interfere with PlanetCAD's
                           operations and in no event shall an audit be
                           conducted more frequently than once each year.

                  customers, without deduction by PlanetCAD of any other costs
                  or expenses related to achievement of the revenue, provided,

                           not assume any obligation or restriction, that would
                           prevent it from performing its obligations under this
                           Agreement.

         10.2     PlanetCAD Representations. PlanetCAD represents and warrants
                  to Dassault Systemes that it owns and/or has valid licenses in
                  all rights, title and interest in and to the WBM Software.

                  PlanetCAD also represents and warrants that, should PlanetCAD
                  develop the Translator, The Translator will materially conform
                  to the specifications set forth in Schedule A for three months
                  following delivery to Dassault Systemes, provided that the
                  Translator is properly used in the operating environment as
                  specified by PlanetCAD. If the Translator does not so conform,
                  PlanetCAD will attempt to make the Translator perform as
                  warranted.

                  PlanetCAD does not warrant that the functions contained in the
                  Translator will meet Dassault Systemes requirements or will
                  enable it to attain the objectives Dassault Systemes has set
                  for itself, or that it will operate in the combination which
                  may be selected for use by Dassault Systemes, or that the
                  operation of the Translator will be uninterrupted or free of
                  Errors. Dassault Systemes shall have exclusive responsibility
                  for (a) program selection to achieve Dassault Systemes'
                  intended results, (b) program installation, (c) taking
                  adequate measures to properly test, operate and use each
                  Translator and (d) results obtained therefrom. Dassault
                  Systemes shall also have exclusive responsibility for
                  selection, use and results of any other programs or
                  programming equipment or services used in connection with the
                  Translator.

         10.3     Dassault Systemes Representations. Dassault Systemes
                  represents and warrants that:

                  (i)      With exception (a) to the CBD Software that has been
                           delivered to Dassault Systemes by PlanetCAD pursuant
                           to the Purchase Agreement, and (b) to the Derivative
                           Works that shall be made by PlanetCAD to the CBD
                           Software according to Section 6 of this Agreement, it
                           owns and/or has valid licenses in all rights, title
                           and interest in and to the CBD Software; and

                  (ii)     The Translator will materially conform to the
                           specifications set forth in Schedule A for three
                           months following delivery to PlanetCAD, provided that
                           the Translator is properly used in the operating
                           environment as specified by Dassault Systemes. If the
                           Translator does not so conform, Dassault Systemes
                           will attempt to make the Translator perform as
                           warranted. If after 60 days from notice by PlanetCAD
                           of the non-conformance, Dassault Systemes has not
                           provided a conforming Translator, PlanetCAD can
                           cancel the license to the non-conforming Translator
                           and PlanetCAD will be entitled to develop itself the
                           Translator according to the provisions of Section 3.1
                           above. In such case, the license

                                       13
<PAGE>   14

                           set forth in this Section 3.4 shall be deemed to be
                           automatically granted to PlanetCAD.

                           Dassault Systemes does not warrant that the functions
                           contained in the Translator will meet PlanetCAD's
                           requirements or will enable it to attain the
                           objectives PlanetCAD has set for itself, or that it
                           will operate in the combination which may be selected
                           for use by PlanetCAD, or that the operation of the
                           Translator will be uninterrupted or free of Errors.
                           PlanetCAD shall have exclusive responsibility for (a)
                           program selection to achieve PlanetCAD's intended
                           results, (b) program installation, (c) taking
                           adequate measures to properly test, operate and use
                           each Translator and (d) results obtained therefrom.
                           PlanetCAD shall also have exclusive responsibility
                           for selection, use and results of any other programs
                           or programming equipment or services used in
                           connection with the Translator.

                           FOR CONFIDENTIAL TREATMENT.]

         11.2     Intellectual Property Infringement Indemnification. Each Party
                  agrees to hold the other Party, its subsidiaries,
                  distributors, assignees and Affiliates, and their respective
                  officers, directors, employees, and shareholders
                  (collectively, the "Indemnities") harmless from and against
                  any claim of any nature, including, but not limited to,
                  administrative, civil or criminal procedures, which is or may
                  be made or raised against a Party's Indemnities by any third
                  party that the use or distribution of the Software that is the
                  subject of this Agreement and owned by the other Party,
                  infringes or violates any third party's patent, copyright,
                  trade secret or other intellectual property right in any
                  country. Indemnification hereunder shall cover all damages,
                  regardless of their nature, settlements, expenses and costs,
                  including costs of investigation, court costs and attorneys'
                  fees. The payment of any indemnification shall be contingent
                  on:

                  (i)      A Party giving prompt written notice to the other
                           Party of any such claim or allegation;

                  (ii)     Cooperation by the indemnified Party with the other
                           Party in its defense against the claim; and

                  (iii)    The indemnified Parties obtaining the other Party's
                           prior written approval of any settlement, if any, by
                           the indemnified Party of such matters, such approval
                           not to be unreasonably withheld.

                  Notwithstanding the foregoing, neither Party shall have the
                  obligation to indemnify the other for any claims of
                  infringement based on any modification by the latest version
                  of its Software, or from the combination of its Software with
                  any other program, to the extent such claim would not have
                  arisen without such combination or from use of the unmodified
                  Software.

         11.3     Additional Remedies. If the operation, distribution or use of
                  any Software that is the subject of this Agreement becomes, or
                  is likely to become, the subject of a claim involving the
                  infringement or other violation of any patent, copyright,
                  trade secret, or other intellectual property rights of any
                  third party, the Parties will jointly determine in good faith
                  what appropriate steps can be agreed upon, with a view towards
                  curing such infringement or other violation, at the Software
                  owner's sole charge. Such steps may include, but are not
                  limited to:

                  (i)      The owner securing the right for the other Party to
                           continue using the Server Software, or

                  (ii)     The owner replacing or modifying the Software so that
                           it becomes non-infringing.

                                       15
<PAGE>   16

                  If no other option is reasonably available, the owner of the
                  Software agrees to use its best efforts to withdraw, at its
                  sole expense, the infringing Software from the market.

12.      TERM AND BREACH OF MATERIAL OBLIGATIONS

         12.1     Term. This Agreement shall come into force as of the Effective
                  Date, and shall remain valid until the expiration of the last
                  copyright or other protection available in any Software herein
                  licensed.

         12.2     Breach of Material Obligations. In the event a Party fails to
                  perform any of its material obligations under this Agreement,
                  the non-breaching Party has given written notice to the other
                  Party of such failure to perform, and the breach is not cured
                  within a sixty day period from receipt of the notice, the
                  non-breaching Party may terminate any and all of its
                  obligations to provide maintenance and support, as set forth
                  in Section 7, to the breaching Party.

13.      MISCELLANEOUS

         13.1     Confidentiality. All communications and information disclosed
                  by one Party to the other Party under this Agreement shall be
                  subject to the terms and conditions of the CNDA.
                  Notwithstanding anything to the contrary in the CNDA, all
                  information relating to the Source Code of the CBD Software
                  and Derivative Works thereof and the WBM Software and
                  Derivative Works thereof and the Translator shall be deemed to
                  be Confidential Information under the CNDA even though they
                  are not marked confidential.

         13.2     Freedom of Action. Except as otherwise provided, nothing
                  contained in this Agreement shall be construed to limit or
                  impair any right of either Party to enter into similar
                  agreements with other parties, or to develop, acquire, license
                  or market, directly or indirectly, other products or services,
                  competitive with those offered by the other Party.

         13.3     Termination of Third Party Licenses. In the event either
                  Dassault Systemes' or PlanetCAD's rights in a third party
                  license that is part of Software subject to the terms of this
                  Agreement is terminated, Dassault Systemes and PlanetCAD will
                  reasonably assist each other in attempting to obtain a
                  satisfactory solution to the loss of such rights. In the event
                  such a solution is not obtained, despite the good faith
                  efforts of the Parties, the Party whose rights in the third
                  party license were terminated may terminate the license
                  granted hereunder as to the specific Software so affected.

         13.4     Additional Instruments. Notwithstanding termination of this
                  Agreement, the Parties covenant and agree to execute and
                  deliver any additional instruments or documents necessary to
                  carry out the general intent of this Agreement, including
                  without limitation patent assignments or any other assignments
                  necessary to

                                       16
<PAGE>   17

                  evidence the ownership of Intellectual Property contemplated
                  hereby or any such additional instruments or documents,
                  including such instruments as may be required by the laws of
                  any jurisdiction, now or in effect or hereinafter enacted,
                  that may affect a Party's rights, title or interest, as
                  applicable, in and to any of the software governed hereby.

         13.5     Irreparable Injury. Each Party acknowledges and agrees that
                  each covenant in this Agreement pertaining to confidential
                  information and ownership of intellectual property is
                  reasonable and necessary to protect and preserve the rights of
                  the other Party in its confidential information and
                  intellectual property, and that any breach by such Party of
                  the terms of this Agreement may result in irreparable injury
                  to the other Party. Each Party, therefore, subject to a claim
                  of laches, estoppel, acquiescence or other delay in seeking
                  relief, consents and agrees that the other Party shall be
                  entitled to seek and obtain a temporary restraining order and
                  a permanent injunction to prevent a breach or contemplated
                  breach of this Agreement and waives any requirement that the
                  other Party post a bond in connection with seeking such
                  injunctive relief.

         13.6     Relationship of the Parties. PlanetCAD and Dassault Systemes
                  are independent contractors, and nothing in this Agreement
                  will create any partnership, joint venture, agency, franchise,
                  sales representative, or employment relationship between the
                  Parties. Neither Party has the authority to act as agent for
                  the other Party or to conduct business in the name of such
                  other Party or make statements, warranties or representations
                  that exceed or are inconsistent with the warranties provided
                  hereunder.

         13.7     Notices. All notices required or permitted shall be given in
                  writing, in the English language, and shall be deemed
                  effectively delivered upon personal delivery or three days
                  after deposit with a carrier by registered mail or other

         13.12    Applicable Law, Venue. This Agreement shall be governed by,
                  and construed in accordance with, the Laws of the State of New
                  York, applicable to contracts executed in and to be performed
                  entirely within that state (without regard to the conflicts of
                  Law provisions thereof). This Agreement shall not be governed
                  by the U.N. Convention on Contracts for the International Sale
                  of Goods. The parties hereto hereby (a) submit to the
                  exclusive jurisdiction of any court of competent jurisdiction
                  sitting in the State of Delaware, The City of Wilmington for
                  the purpose of any Action arising out of or relating to this
                  Agreement brought by any party hereto, and (b) agree, to the
                  fullest extent permitted by applicable law, to waive, and not
                  to assert by way of motion, defense, or otherwise, in any such
                  Action, any claim that is not subject personally to the
                  jurisdiction of the above-named courts, that its property is
                  exempt or immune from attachment or execution, that the Action
                  is brought in an inconvenient forum, that the venue of the
                  Action is improper, or that this Agreement may not be enforced
                  in or by any of the above-named courts.

         13.13    Waiver of Jury Trial. EACH OF THE PARTIES HERETO HEREBY WAIVES
                  TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW ANY RIGHT IT
                  MAY HAVE TO A TRIAL BY JURY WITH RESPECT TO ANY ACTIONS OR
                  PROCEEDINGS DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN
                  CONNECTION WITH THIS AGREEMENT, OR THE TRANSACTIONS
                  CONTEMPLATED HEREUNDER.

         13.14    Counterparts. This Agreement may be executed in one or more
                  counterparts, each of which when executed shall be deemed to
                  be an original but all of which taken together shall
                  constitute one and the same agreement.

         13.15    No Waiver. The failure of either Party to enforce any
                  provision of this Agreement shall not constitute a waiver of
                  the right to subsequently enforce such provision, or any other
                  provision of this Agreement.

         13.16    Force Majeure. Neither Party shall be held liable for any
                  failure to perform any of its obligations under this Agreement
                  for as long as, and to the extent that such failure is due to
                  an event of force majeure. An event of force majeure shall
                  include general strikes, lockouts, acts of God, acts of war,
                  mobilization of troops, fire, extreme weather, flood, or other
                  natural calamity, embargo, acts of governmental agency,
                  government or any other laws or regulations.

         13.17    Expenses. Except as expressly provided for in this Agreement,
                  each Party shall bear its own expenses incurred in connection
                  with this Agreement, including without limitation travel and
                  living expenses incurred by that Party's employees.

         13.18    Assignment; Subcontracting; Third Party Beneficiaries.

                  (a)      This Agreement may be assigned or otherwise
                           transferred, by operation of law or otherwise without
                           the express written consent of PlanetCAD and Dassault
                           Systemes, but in such event the assigning Party shall
                           give notice to the non-assigning Party and the
                           non-assigning Party shall have the right to terminate
                           its maintenance and support obligations under this
                           Agreement within the 30 day period following receipt
                           of such notice.

                  (b)      Either Party may assign or otherwise transfer all or
                           part of this Agreement to any of its Affiliates and
                           for as long as it remains an Affiliate; provided that
                           no such assignment shall relieve a Party of any of
                           its obligations under this Agreement. In the event
                           there is a change of Control of an Affiliate which
                           terminates its status as an Affiliate of the party to
                           this Agreement, and this Agreement has been assigned
                           to such an Affiliate, this Agreement shall be
                           assigned back to the party within 6 months of the
                           effective date of the change of Control.

                  (c)      Either Party may subcontract services necessary to
                           perform the obligations set forth in this Agreement
                           provided that (i) any and all such subcontractors
                           shall have entered into agreements with the
                           subcontracting Party sufficient to enable that Party
                           to comply with all terms and conditions of this
                           Agreement; and (ii) the subcontracting Party shall
                           have obtained prior approval from the other Party,
                           which will not be unreasonably withheld, (a) of its
                           subcontractors, and (b) the method the subcontracting
                           Party will make the Source Code of any Software that
                           is the subject of this Agreement available to said
                           subcontractors, in the event access to such Source
                           Code is necessary.

                  (d)      This Agreement shall be binding upon and inure solely
                           to the benefit of the Parties hereto and their
                           permitted assigns, subcontractor or transferee, and
                           nothing herein, express or implied, is intended to or
                           shall confer upon any other person, including,
                           without limitation, any union or any employee or
                           former employee of either Party, any legal or
                           equitable right, benefit or

                                       19

                           remedy of any nature whatsoever, including, without
                           limitation, any rights of employment for any
                           specified period, under or by reason of this
                           Agreement.

         13.19    Trademarks. Notwithstanding any other provisions of this
                  Agreement, neither Party shall have the right under this
                  Agreement to use the other Party's trademarks or trade names
                  in connection with any product, service, promotion, public
                  announcement, advertisement or other publication, without
                  securing the prior written consent of such other Party.

         13.20    Third Party Licenses. Each party is relieved of its
                  obligations, if any, to (i) deliver the Source Code of a
                  product licensed hereunder or (ii) authorize the creation of
                  Derivative Works from Source Code hereunder to the extent that
                  fulfilling such obligations would cause such party to breach
                  any third party license agreement entered into by such party
                  after the Effective Date.

         IN WITNESS WHEREOF, the Parties hereto have caused this Agreement to be
executed in duplicate originals by their duly authorized officers or
representatives.
