adverse change in the assets, prospects, results of operation or financial

Securities Act of 1968, as

                                       26
<PAGE>

amended, and neither WI nor any authorized agent acting on its behalf will take
any action hereafter that would cause the loss of such exemption.

          (j) Disclosure. WI has fully provided the TRW with all the information
that it has requested for deciding whether accept the Common Stock as
consideration hereunder and all information that WI believes is reasonably
necessary to enable the TRW to make such decision. Neither this Agreement nor
any other statements or certificates made or delivered in connection herewith or
therewith contains any untrue statement of a material fact or omits to state a
material fact necessary to make the statements herein or therein not misleading.

          (k) Corporate Documents. Except for amendments necessary to satisfy
representations and warranties or conditions contained herein (the form of which
amendments has been approved by TRW), the Articles and Bylaws of WI are in the
form previously provided to TRW. The minute books of WI provided to TRW contain
a complete summary of all meetings of directors and shareholders since the time
of incorporation.

          (l) Proprietary Information and Employee Stock Purchase Agreements.
Each employee, officer and consultant of WI has executed a Proprietary
Information and Inventions Agreement in the form provided to special counsel to

officers or consultants are in violation thereof, and WI will use its best
efforts to prevent any such violation.

          (m) Patents and Trademarks. WI has sufficient title and ownership of
all patents, trademarks, service marks, trade names, copyrights, trade secrets,
information, proprietary rights and processes necessary for its business as now
conducted and as proposed to be conducted without any conflict with or
infringement of the rights of others. There are no outstanding options,
licenses, or agreements of any kind relating to the foregoing, nor is WI bound
by or a party to any options, licenses or agreements of any kind with respect to
the patents, trademarks, service marks, trade names, copyrights, trade secrets,
licenses, information, proprietary rights and processes of any other person or
entity. WI has not received any communications alleging that WI has violated or,
by conducting its business as presently conducted or proposed to be conducted,
would violate any of the patents, trademarks, service marks, trade names,
copyrights or trade secrets or other proprietary rights of any other person or
entity, or that any intellectual property owned by WI is invalid or
unenforceable. WI is not aware that any of its employees is obligated under any
contract (including licenses, covenants or commitments of any nature) or other
agreement, or subject to any judgment, decree or order of any court or
administrative agency, that would interfere with the use of his or her best
efforts to promote the interests of WI or that would conflict with WI's business
as presently conducted or proposed to be conducted. Neither the execution nor
delivery of this Agreement, nor the carrying on of WI's business by the
employees of WI, nor the conduct of WI's business as presently conducted or
proposed to be conducted, will, to the best of WI's knowledge, conflict with or
result in a breach of the

                                       27
<PAGE>

terms, conditions or provisions of, or constitute a default under, any contract,
covenant or instrument under which any of such employees is now obligated. WI
does not believe it is or will be necessary to utilize any inventions of any of
its employees (or people it currently intends to hire) made prior to their
employment by WI.

          (n) Compliance with Other Instruments.

               (a) WI is not in violation or default of any provision of its
Articles or Bylaws, or of any instrument, judgment, order, writ, decree or
contract to which it is a party or by which it is bound, or, to the best of its
knowledge, of any provision of any federal or state statute, rule or regulation
applicable to WI. The

execution, delivery and performance of this Agreement and TRW' Rights Agreement,
and the consummation of the transactions contemplated hereby and thereby will
not result in any such violation or be in conflict with or constitute, with or
without the passage of time and giving of notice, either a default under any
such provision, instrument, judgment, order, writ, decree or contract or an
event that results in the creation of any lien, charge or encumbrance upon any
assets of WI or the suspension, revocation, impairment, forfeiture, or
nonrenewal of any material permit, license, authorization, or approval
applicable to WI, its business or operations or any of its assets or properties.

               (b) To the knowledge of WI, WI has avoided every condition, and
has not performed any act, the occurrence of which would result in WI's loss of
any right granted under any license, distribution or other agreement.

directors, affiliates, or any affiliate thereof.

               (b) There are no agreements, understandings, instruments,
contracts, proposed transactions, judgments, orders, writs or decrees to which

or made any distribution upon or with respect to any class or series of its
capital stock, (ii) incurred any indebtedness for money borrowed or any other
liabilities individually in excess of $20,000 or, in the case of indebtedness
and/or liabilities individually less than $20,000, in excess of $75,000 in the
aggregate, (iii) made any loans or advances to or

                                       28
<PAGE>

guaranteed any liabilities of any person, other than ordinary advances to
employees or consultants for travel expenses, or (iv) sold, exchanged or
otherwise disposed of any of its assets or rights, other than the sale of its
inventory in the ordinary course of business.

               (d) For the purposes of subsections (b) and (c) above, all
indebtedness, liabilities, agreements, understandings, instruments, contracts
and proposed transactions involving the same person or entity (including persons
or entities WI has reason to believe are affiliated therewith) shall be
aggregated for the purpose of meeting the individual minimum dollar amounts of
such subsections.

               (e) WI has not engaged in the past three (3) months in any
discussion (i) with any representative of any corporation or corporations
regarding the consolidation or merger of WI with or into any such corporation or
corporations, (ii) with any corporation, partnership, association or other
business entity or any individual regarding the sale, conveyance or disposition
of all or substantially all of the assets of WI or a transaction or series of
related transactions in which more than fifty percent (50%) of the voting power
of WI is disposed of, or (iii) regarding any other form of acquisition,
liquidation, dissolution or winding up of WI.

               (f) WI is not a party to and is not bound by any contract,
agreement or instrument, or subject to any restrictions under its Articles or
Bylaws that presently adversely affects its business as now conducted.

          (p) Related-Party Transactions. No employee, officer, director or
stockholder of WI or member of his or her immediate family is indebted to WI,
nor is WI indebted (or comitted to make loans or extend or guarantee credit) to
any of them. To the best of WI's knowledge, none of such persons has any direct
or indirect ownership interest in any firm or corporation with which WI is
affiliated or with which WI has a business relationship, or any firm or
corporation that competes with WI, except that employees, officers, or directors
of WI and members of their immediate families may own stock in publicly traded
companies that compete with WI. No member of the immediate family of any officer
or director of WI is directly or indirectly interested in any material contract
with WI.

          (q) Permits. WI has all franchises, permits, licenses, and any similar
authority necessary for the conduct of its business as now being conducted by
it, the lack of which could materially and adversely affect the business,
properties, prospects, results of operations or financial condition of WI, and
WI believes it can obtain, without undue burden or expense, any similar
authority for the conduct of its business as planned to be conducted. WI is not
in default in any material respect under any of such franchises, permits,
licenses, or other similar authority.

          (r) Environmental and Safety Laws. To the best of its knowledge, WI is
not in violation of any applicable statute, law or regulation relating to the
environment or occupational health and safety, and to the best of its knowledge,
no material expenditures are or will be required in order to comply with any
such existing statute, law or regulation.

<PAGE>

          (s) Manufacturing and Marketing Rights. WI has not granted rights to
manufacture, produce, assemble, license, market, or sell its products to any
other person and is not bound by any agreement that affects WI's exclusive right
to develop, manufacture, assemble, distribute, market or sell its products.

          (t) Registration Rights. Except as provided in TRW' Rights Agreement,
WI has not granted or agreed to grant any registration rights, including
piggyback rights, to any person or entity.

          (u) Title to Property and Assets. WI owns its property and assets free
and clear of all mortgages, liens, loans and encumbrances, except such
encumbrances and liens that arise in the ordinary course of business and do not
materially impair WI's ownership or use of such property or assets. With respect
to the property and assets it leases, WI is in compliance with such leases and,
to the best of its knowledge, holds a valid leasehold interest free of any
liens, claims or encumbrances.

          (v) Financial Statements.

               (a) WI has delivered to TRW its unaudited financial statements

and statement of cash flows, including notes thereto) at December 31, 1998 and
for the fiscal year then ended, and its unaudited financial statements (balance
sheet and profit and loss statement) as at and for the nine month period ended
September 30, 1999 (the "Financial Statements") (i) the pro forma consolidated
balance sheet of WI and its Subsidiaries as at September 30, 1999 and the pro
forma combined historical income statements dated September 30, 1999, each such
balance sheets and income statements taking into account all transactions
contemplated hereby and by the Related Agreements, such balance sheet and income
statements being attached hereto as Schedule 2.22(a)(ii); and (iii) the
projections of the future performance of WI and its Subsidiaries for the
five-year period following the Closing Date, on a consolidated basis, including
income, net profits, and cash flows, as attached hereto as Schedule 2.22(a)(iii)
(the "Projections"). The Financial Statements have been prepared in accordance
with generally accepted accounting principles applied on a consistent basis
throughout the periods indicated and with each other, except that unaudited
Financial Statements may not contain all footnotes required by generally
accepted accounting principles applicable to audited annual financial
statements. The Financial Statements fairly present the financial condition and
operating results of WI as of the dates, and for the periods, indicated therein,
subject in the case of unaudited Financial Statements to normal year-end audit
adjustments. Except as set forth in the Financial Statements, WI has no material
liabilities, contingent or otherwise, other than (i) liabilities incurred in the
ordinary course of business subsequent to September 30, 1999 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 the Financial Statements, which, in both cases, individually or in
the aggregate, are not material to the financial condition or operating results
of WI. Except as disclosed in the Financial Statements, WI is not a guarantor or
indemnitor of any indebtedness of any other

                                       30

Subsidiaries and the pro forma consolidated income statements referred to in
Section 2.22(a)(ii) have been prepared by management of WI on a reasonable
basis, taking into consideration the effect of the transactions contemplated
hereby and by the Related Agreements, and WI is not aware of any fact which
casts any doubt on the accuracy or completeness thereof. After giving effect to
the transactions contemplated hereby and by the Related Agreements, WI and its
Subsidiaries will have no material liabilities, contingent or otherwise, which
are not referred to in such balance sheet or in the notes thereto.

               (c) The Projections constitute a reasonable basis for the
assessment of the future performance of WI and its Subsidiaries, on a
consolidated basis, during the periods indicated therein, and all material
assumptions used in the preparation of the Projections are set forth in the
notes thereto.

          (w) Changes. Since September 30, 1999 there has not been:

               (a) any change in the assets, liabilities, financial condition or
operating results of WI from that reflected in the Financial Statements, except
changes in the ordinary course of business that have not been, in the aggregate,
materially adverse;

               (b) any damage, destruction or loss, whether or not covered by

copyrights, trade secrets or other intangible assets;

               (h) any resignation or termination of employment of any key
officer of WI; and WI, to the best of its knowledge, does not know of the
impending resignation or termination of employment of any such officer;

               (i) receipt of notice that there has been a loss of, or material
order cancellation by, any customer of WI;

               (j) any mortgage, pledge, transfer of a security interest in, or
lien, created by WI, with respect to any of its material properties or assets,

               (m) to the best of WI's knowledge, any other event or condition
of any character that might materially and adversely affect the assets,
properties, financial condition, operating results or business of WI (as such
business is presently conducted and as it is proposed to be conducted); or

               (n) any agreement or commitment by WI to do any of the things
described in the Section 2.24.

          (x) Employee Benefit Plans. WI does not have any Employee Benefit Plan
as defined in the Employee Retirement Income Security Act of 1974.

          (y) Tax Returns, Payments and Elections. WI has filed all tax returns
and reports as required by law. These returns and reports are true and correct
in all material respects. WI has timely paid all taxes and other assessments
due, except those contested by it in good faith that are listed in the Schedule
of Exceptions. The provision for taxes of WI as shown in the Financial
Statements is adequate for taxes due or accrued as of the date thereof. WI has
not elected pursuant to the Internal Revenue Code of 1986, as amended (the
"Code"), to be treated as a Subchapter S corporation or a collapsible
corporation pursuant to Section 1362(a) or Section 341(f) of the Code, nor has
it made any other elections pursuant to the Code (other than elections that
relate solely to methods of accounting, depreciation or amortization) that would
have a material effect on WI, its financial condition, its business as presently
conducted or proposed to be conducted or any of its properties or material
assets. WI has never had any tax deficiency proposed or assessed against it and
has not executed any waiver of any

                                       32
<PAGE>

statute of limitations on the assessment or collection of any tax or
governmental charge.

None of WI's federal income tax returns and none of its state income or
franchise tax or sales or use tax returns has ever been audited by governmental
authorities. Since the date of the Financial Statements, WI has made adequate
provisions on its books of account for all taxes, assessments and governmental
charges with respect to its business, properties and operations for such period.
WI has withheld or collected from each payment made to each of its employees,
the amount of all taxes (including, but not limited to, federal income taxes,
Federal Insurance Contribution Act taxes and Federal Unemployment Tax Act taxes)
required to be withheld or collected therefrom, and has timely paid the same to
the proper tax receiving officers or authorized depositaries.

          (z) Insurance. WI has in full force and effect fire and casualty
insurance policies, with extended coverage, sufficient in amount (subject to
reasonable deductibles) to allow it to replace any of its properties that might
be damaged or destroyed. WI does not have any term life insurance, payable to
WI, on the lives of any of its officers, directors or employees. WI has in full
force and effect products liability and errors and omissions insurance in
amounts customary for companies similarly situated.

          (aa) Minute Books. The minute books of WI provided to TRW contain a
complete summary of all meetings directors and stockholders since the time of
incorporation and reflect all transactions referred to in such minutes
accurately in all material respects.

          (bb) Labor Agreements and Actions. WI is not bound by or subject to
(and none of its assets or properties is bound by or subject to) any written or
oral, express or implied, contract, commitment or arrangement with any labor
union, and no labor union has requested or, to the best of WI's knowledge, has
sought to represent any of the employees, representatives or agents of WI. There
is no strike or other labor dispute involving WI pending, or to the best of WI's
knowledge, threatened, that could have a material adverse effect on the assets,
properties, financial condition, operating results, or business of WI (as such
business is presently conducted and as it is proposed to be conducted), nor is
WI aware of any labor organization activity involving its employees. WI is not
aware that any officer or key employee, or that any group of key employees,
intends to terminate their employment with WI, nor does WI have a present
intention to terminate the employment of any of the foregoing. The employment of
each officer and employee of WI is terminable at the will of WI. To the best of
its knowledge, WI has complied in all material respects with all applicable
state and federal equal employment opportunity and other laws related to
employment.

          (cc) Section 83(b) Elections. To the best of WI's knowledge, all
individuals who have purchased shares of WI's Common Stock have timely filed
elections under Section 83(b) of the Code and any analogous provisions of
applicable state tax laws.

          (dd) Real Property Holding Company. WI is not a real property holding
company within the meaning of Section 897 of the Code and Section 1.897-2(b) of
the Treasury Regulations promulgated by the Internal Revenue Service.

          (ee) Solvency. Prior to, upon and immediately after consummation of
the transactions contemplated hereby, WI is solvent, has tangible and intangible
assets having a fair value in excess of the amount required to pay its probable
liabilities on its existing debts as they become absolute and matured, and has
access to adequate capital for the conduct of its business and the ability to
pay its debts from time to time incurred in connection therewith as such debts
mature.

          (ff) Defaults. No Default or Event of Default exists on the date
hereof. WI is not in default under any provisions of its Articles or under any
material provisions of any franchise, contract, agreement, lease or other
instrument to which it is a party or by which it or its property is bound or in
material violation of any law, judgment, decree or governmental order, rule or
regulation.

          (gg) Year 2000. To WI's knowledge, all hardware and software products
used by WI in the administration and the business operations of WI will be able
to accurately process date data (including, but not limited to calculating,
comparing and sequencing) from, into and between the twentieth century (through
year 1999), the year 2000 and the twenty-first century, including leap year
calculations, when used in accordance with the product documentation
accompanying such hardware and software products. Undefined capitalized terms
used in this Section 10.2 (WI's Warranties) will have the meaning ascribed to
them in the Series F Preferred Stock Purchase Agreement.

     WI represents that as of the Effective Date, it is WI's intention to
continue development of the Spitfire Products, and to manufacture and market
commercial versions of such products. Nothing contained in this Agreement will

any Spitfire Invention, to market any product incorporating any such
Intellectual Property or invention, or to have an Initial Public Offering, and
WI has made no representation or warranty to TRW regarding these or any other
subjects, except for the specific representations set forth in Section 10.2
(WI's Warranties) and 10.3 (No Commitment) of this Agreement and in Section 2 of
the Series F Preferred Stock Purchase Agreement.
