     The Company, Seller, Fleischer and Tighe jointly and severally represent
and warrant (except with respect to (i) Section 2.2(b), in which case the Seller
represents and warrants as to itself only and (ii) Section 2.4, in which case

statements contained in this Article II are true and correct, except as set
forth in the letter provided by the Seller and the Company to Buyer which is
attached hereto (the "Disclosure Letter").

     2.1  ORGANIZATION, QUALIFICATION AND CORPORATE POWER.

     The Company is a corporation duly organized, validly existing and in
corporate good standing under the laws of the State of Delaware. The Company is
duly qualified to conduct business and is in good standing under the laws of
each jurisdiction in which the nature of its business or the ownership or
leasing of its properties requires such qualification. The Company has the
corporate power and authority to carry on the businesses in which it is engaged
and to own and use the properties owned and used by it. The Company has
furnished to Buyer true and complete copies of its Certificate of Incorporation
and By-laws, each as amended and as in effect on the date hereof (hereinafter
"Charter" and "By-laws," respectively). The Company is not in default under or
in violation of any provision of its Charter or By-laws, each as amended to
date.

     2.2  CAPITALIZATION.

          (a)  As of the date hereof, the authorized capital stock of the

shares are issued and outstanding and no shares are held in the treasury of the
Company, (ii) 25,000 shares of Class B Common Stock (non-voting), par value
$.01 per share (the "Class B Common Stock"), of which no shares are issued and
outstanding, and (iii) 25,000,000 shares of Preferred Stock, par value $.01 per
share (the "Preferred Stock") of which no shares are issued and outstanding.
Section 2.2 of the Disclosure Letter sets forth a complete and accurate list of
(i) the sole stockholder of the Company, indicating the number of shares of
Common Stock held by such stockholder, and (ii) all holders of any options and
warrants, indicating the number of shares subject to each and the exercise
price thereof. All outstanding Common Stock, options and warrants are listed in
Section 2.2 of the Disclosure Letter. All of the issued and outstanding shares
of Common Stock are duly authorized, validly issued, fully paid, nonassessable
and free of all preemptive rights. There are no declared or accrued but unpaid
dividends with regard to any issued and outstanding Common Stock. The holder of
all the issued and outstanding shares of Common Stock has no reasonable basis
for asserting rights to rescind the purchase of any such shares. Other than as
set forth in Section 2.2 of the Disclosure Letter, there are no outstanding
options, warrants, rights, calls, convertible instruments, agreements or
commitments to which the Company is a party or which are binding upon the
Company providing for the issuance, disposition or acquisition of any of its
equity securities. There are no outstanding or authorized stock appreciation,
phantom

voting trusts, proxies, or understandings with respect to the voting, or
registration under the Securities Act (as defined herein), of any shares of

the issued and outstanding shares of Common Stock were issued in material
compliance with applicable federal and state securities laws.

          (b)  The Seller has good and valid title to the Stock, free and clear
of any liens, claims, charges, security interests, options or other legal or
equitable encumbrances of any kind. No person or entity (other than Seller with
respect to the Stock) has any power or right, whether or not shared with any
other person or entity, to dispose of or direct the disposition of any Company
securities or vote or direct the voting of any Company securities. Upon
consummation of the transactions contemplated by this Agreement, Buyer will
acquire good and valid title to the Stock, free and clear of any liens, claims,
charges, security interests, options or other legal or equitable encumbrances
of any kind.

          The Company has the corporate power and authority to execute and
deliver this Agreement and to perform its obligations hereunder. The execution

Agreement and the consummation by the Company of the transactions contemplated
hereby have been duly and validly authorized by all necessary corporate action
on the part of the Company. This Agreement has been duly and validly executed
and delivered by the Company and Seller, and assuming the due authorization,

insolvency, fraudulent conveyance, reorganization, moratorium and other similar
laws affecting the enforcement of creditors' rights generally, and except that
the availability of equitable remedies, including specific performance, is
subject to the discretion of the court before which any proceeding therefor may
be brought.

dividend or otherwise transfer, in compliance with applicable securities laws,
the Purchase Stock to Seller's sole shareholders, Fleischer and Tighe, or to
compensate any professional engaged by Seller in connection with this
Agreement. Seller and Martin each recognize that (i) the Purchase Stock will

currently exists for any of Buyer's securities, (iii) no such market is
expected to develop in the foreseeable future and (iv) Seller and Martin will

Returns, except such as are being contested in good faith by appropriate
proceedings (to the extent any such proceedings are required) and with respect
to which the Company or Seller is maintaining reserves adequate for their
payment, and which are described in Section 2.10 of the Disclosure Letter. The
accrued but unpaid Taxes of the Company for tax periods through the date of the

Taxes attributable to the period January 1, 1999 through the Closing Date are
attributable to the conduct by the Company of its operations in the Ordinary

or collected and, to the extent required, have been paid to the proper
Governmental Entity, except such as are being contested in good faith by
appropriate proceedings (to the extent any such proceedings are required) and

for their payment and which are described in Section 2.10 of the Disclosure
Letter.

complete copies of all such suits, actions or proceedings or written notices to
the extent the Company is not prohibited from disclosing the same under any
applicable court order. The manufacturing, marketing, licensing or sale of the

Property rights of the Company are not being infringed by activities, products
or services of any third party.

          (d)  The Company has taken reasonable security measures to safeguard

proprietary information and the assignment to the Company of all Intellectual
Property arising from the services performed for the Company. Buyer has
received a copy of the form or forms of such agreement and a list of all
subject officers, employees and consultants. No current or prior officers,
employees or consultants of the Company or Parent claim any ownership interest
in any material Intellectual Property as a result of having been involved in
the development of such property while employed by or consulting to the
Company, or otherwise. All of the Intellectual Property has been developed by
employees of or consultants to the Company within the scope of their employment
or consulting.

          (e)  The Company has the right, title and interest in and to all
material software development tools, whether or not entirely developed

software included in the Intellectual Property.

Stockholders has any knowledge of, or reason to know of, any defects in the

customers, and there are no errors in any documentation, specifications,
manuals, user guides, promotional material, technical documentation, drawings,
flow charts, diagrams, source language statements, demo disks and other written
materials related to, associated with or used or produced in the development of
the Company's software and/or the products and services provided to the
Company's customers, which defects or errors would reasonably be expected to
have, individually or in the aggregate, a Material Adverse Effect on the
Company. The Company's products operate in all material respects as represented
in the specifications, manuals, user guides, promotional materials and demo
disks for such products. The occurrence in or use of dates on or after January
1, 2000 (the "Millennial Dates") by the Company's software and/or products and
services currently provided to the Company's customers will not materially
adversely affect the performance of the software with respect to date dependent
data, computations, output or other functions (including without limitation,
calculating, computing and sequencing), and the software will create, sort and
generate output data related to or including Millennial Dates without material
errors or material omissions, provided, however, in each case, each software or
hardware product used in

                                      -13-

<PAGE>   14

conjunction with the computer software products are also able to create,

determination letter has been revoked and revocation has not been threatened,
and no such Employee Benefit Plan has been amended since the date of its most

reasonably be expected to subject the Company or any ERISA Affiliate to any
material fine, penalty, tax or liability of any kind imposed under ERISA or the

     2.21 ENVIRONMENTAL MATTERS.

          (a)  The Company is now and has at all times been in compliance with
all applicable Environmental Laws except for such non-compliance that would not
have a Material Adverse Effect. There is no pending or, to the Company's
knowledge, threatened civil or criminal litigation, written notice of
violation, formal administrative proceeding, or investigation, inquiry or

<PAGE>   20

(vii) underground and other storage tanks or vessels, abandoned, disposed
or discarded barrels, containers and other closed receptacles; (viii) health
and safety of employees and other persons. As used above, the terms "release"
and "environment" shall have the meaning set forth in the federal Comprehensive
Environmental Compensation, Liability and Response Act of 1980 ("CERCLA").

          (b)  There have been no releases of any Materials of Environmental
Concern (as hereinafter defined) into the environment at any space leased,
operated or controlled by the Company during the time that such space was
leased, operated or controlled by the Company and, to the knowledge of the
Company, there have been no releases of any Materials of Environmental Concern
into the environment at any parcel of real property or any facility during the
time when such real property or facility was leased, operated or controlled by
the Company. The Company is not aware of any other releases of Materials of
Environmental Concern that could reasonably be expected to have an impact on
the real property or facilities owned, leased, operated or controlled by the
Company. For purposes of this Agreement, "Materials of Environmental Concern"
means any chemicals, pollutants or contaminants, hazardous substances (as such
term is defined under CERCLA), hazardous wastes (as such terms are defined
under the federal Resources Conservation and Recovery Act), toxic materials,
oil or petroleum and petroleum products, or any other material subject to
regulation under any Environmental Law.

business, except where non-compliance would not reasonably be expected to have
a Material Adverse Effect on the Company.

licenses, registrations, certificates, orders or approvals from any
Governmental Entity (including without limitation those issued or required
under applicable export laws or regulations) ("Permits") issued to or held by
the Company. Such listed Permits are the only Permits that are required for the
Company to conduct its business as presently conducted, except for those the
absence of which would not have a Material Adverse Effect on the Company. Each
such Permit is in full force and effect and, to the knowledge of the Company,
no suspension or cancellation of any such Permit is threatened, and there is no
reasonable basis for believing that any such Permit will not be

                                      -20-

taxes) set forth on the Most Recent Balance Sheet. In the case of any Straddle

as if such taxable period ended on and included the Closing Date; provided that
all Straddle Period Taxes that are real property Taxes of the Company shall be

          (b)  Buyer shall notify Seller in writing upon receipt by Buyer of
notice of any pending or threatened federal, state, local or foreign Tax audits
or assessments which may affect the Tax liabilities of the Company for which
Seller would be required to indemnify Buyer pursuant to the terms of this
Agreement, provided that failure to comply with this provision shall not affect
Buyer's right to indemnification hereunder except to the extent Seller are
actually prejudiced by such failure. Seller shall have the sole right to
represent the Company's interests in any Tax audit or administrative or court
proceeding relating to taxable periods ending on or before the Closing Date,
and to employ counsel of its choice at its cost and expense, provided, however,
that Buyer and its representatives shall be permitted, at Buyer's cost and
expense, to be present at, and participate in, any such audit or proceeding.
Notwithstanding the foregoing, Seller shall not settle, either administratively
or after the commencement of litigation, any claim for Taxes without Buyer's
consent, which consent shall not be unreasonably withheld.

          (c)  Notwithstanding any other provisions of this Agreement to the
contrary, Buyer shall pay, or cause to be paid, any and all sales, use,

to be filed on a timely basis (in each case, at its own cost and expense) all
Tax Returns with respect to the Company for taxable periods ending on or prior
to the Closing Date. Such returns shall be prepared in a manner consistent with
Seller's past practices and elections and shall be submitted to Buyer no less
than thirty (30) days prior to being timely filed for Buyer's review and
comment. Seller shall accept and incorporate any Buyer comments that are (i)
delivered to Seller in a timely fashion and (ii) not unreasonable or
inconsistent with past practices. Seller shall provide Buyer, for Buyer's
review and comment, with advance copies of such Tax Returns (including any
extensions thereto and reflecting Buyer's comments, if any) as well as copies
of filed Tax Returns (including any extensions thereto). Seller shall remit (or
cause to be remitted) any Taxes due in respect of such Tax Returns.

          (e)  Buyer shall prepare or cause to be prepared and shall file or
cause to be filed on a timely basis (in each case at its own cost and expense)
all other Tax Returns with respect to the Company. Such returns shall be
prepared in a manner consistent with Seller's past practices and elections and
shall be submitted (together with a statement calculating Seller's obligations
pursuant to this Section) to Seller for Seller's review and comment no less
than thirty (30) days prior to being timely filed. Buyer shall accept and
incorporate any Seller comments that are (i) delivered to Buyer in a timely
fashion and (ii) not unreasonable or inconsistent with past practices. In
connection therewith, Seller shall be responsible for and shall pay any Taxes
for which Seller has agreed to indemnify Buyer pursuant to the terms of this
Agreement to the extent such taxes were not reserved on the books of the
Company as of the Closing Date. Buyer shall provide Seller, for Seller's review
and comment, with copies of any such Tax Returns, containing Seller's comments,
if any, at least twenty days prior to the due date thereof (giving effect to
any extensions thereto), accompanied by a statement calculating Seller'
obligation

                                      -31-

<PAGE>   32

pursuant to this Section. Seller shall pay to Buyer the amount of the
obligation within ten days of receiving copies of such Tax Returns unless the
parties are unable to agree on the amount of Seller's obligation hereunder in
which case such dispute shall be resolved by independent accountants acceptable
to both parties whose fees, costs and expenses shall be paid by Buyer and
Seller in proportion to each party's respective liability for such Taxes as
determined by such accountants. Within five days of such determination, Seller
shall pay Buyer the amount of Taxes for which Seller is determined to be liable
by such accountants, together with interest on such amount at the Prime Rate
from the date on which Seller's payment obligation originally arose.

          (f)  After the Closing Date, each of Buyer and Seller shall: (i)
timely sign and deliver such certificates and forms as may be necessary or
appropriate to establish an exemption from (or otherwise reduce), or file Tax
Returns or other reports with respect to, Taxes described herein; (ii) assist
the other party in preparing any Tax Returns which such other party is
responsible for preparing and filing, including giving access, upon reasonable
request, to information, records and documents necessary to prepare such Tax
Returns (including in the case of Seller, a copy of the Company's tax files
used in connection with the Company's preparation of Tax Returns); and (iii)
cooperate fully in preparing for any audits of, or disputes with taxing
authorities regarding, Taxes of the Company.

     7.5  INTER-COMPANY BILLING

     Until all business relations between Seller and the Company have ceased,
Seller and the Company shall each identify the employees of such Party who
perform services for the other party and shall establish a billing rate for
each such employee. Each of the Seller and the Company shall record the time of
each such employee in the cost accounting records of the company responsible
for paying such employee and shall bill the other Party monthly for the work
performed, using the billing rate established in accordance with this Section
4.2.

     7.6  SENIORITY OF PURCHASE NOTE.

     At the Closing, the Purchase Note will be subordinate to the interests of
Silicon Valley Bank (the "Bank") pursuant to the terms of the Subordination
Agreement by and among the Seller, the Selling Stockholders and the Bank (the
"Subordination Agreement"). If, at December 15, 1999, the Purchase Note has not
been paid in full and discharged, Buyer shall (i) discharge its obligations to
the Bank such that (A) the Subordination Agreement shall terminate and have no
further effect on the Purchase Note and (B) the holder of the Purchase Note
shall be first in priority with respect to both the security interest in all
collateral described in the Security Agreement and payment of the obligations
evidenced by the Purchase Note and (ii) pay to Seller on or before December 15,
1999, the lesser of (A) Seller's tax liabilities incurred directly from this
Agreement and the transactions contemplated hereby (including, without
limitation, any conveyance of Seller's Purchase Stock to either or both of
Fleischer and Tighe) and (B) One Million Five Hundred Thousand Dollars
($1,500,000). Notwithstanding anything to the contrary contained herein or
elsewhere, this provision shall survive Closing and shall continue in effect
until the Purchase Note is duly paid.

                                  ARTICLE VIII
                                INDEMNIFICATION

     8.1  INDEMNIFICATION; LIMITATIONS ON INDEMNIFICATION.

          (a)  Seller and the Selling Stockholders, jointly and severally as to
Seller and Selling Stockholders, and jointly and severally among the Selling
Stockholders, will indemnify and hold harmless Buyer and the Company and their
respective officers, directors, agents and employees, and each person, if any,
who controls or may control Buyer or the Company within the meaning of the
Securities Act (hereinafter referred individually as an "Indemnified Person"
and collectively as "Indemnified Persons") from and against any and all losses,
costs, damages, liabilities and expenses arising from claims, demands, actions,
causes of action, including, without limitation reasonable legal fees, net of
any recoveries under existing insurance policies, Tax benefit received by Buyer
or its affiliates as a result of such damages, indemnities from third parties
or in the case of third party claims, by any amount actually recovered by Buyer
or its affiliates pursuant to counterclaims made by any of them directly
relating to the facts giving rise to such third party claims (collectively,
"Damages") arising out of any misrepresentation or breach of or default in
connection with any of the representations, warranties, covenants and
agreements given or made by the Company and/or Seller in this Agreement.

          (b)  No Indemnified Person shall be entitled to indemnification under
this Article VIII from and against any and all Damages until the aggregate
amount of such Damages incurred by all Indemnified Persons exceeds $100,000, in
which event such Indemnified Person shall be entitled to indemnification only
for the amount of all such Damages in excess of $100,000 in the aggregate.
Notwithstanding anything to the contrary set forth herein, the aggregate
indemnification obligations hereunder shall not exceed $5,000,000, and any
individual liability of the Selling Stockholders shall be satisfied solely
against the Escrow Amount without further personal liability hereunder.
Notwithstanding anything to the contrary set forth herein, the above-referenced
maximum and minimum limitations on indemnification liability hereunder shall
not be applicable to any indemnification and/or reimbursement obligations
pursuant to Section 7.3 (and any claims or payments made pursuant to Section
7.3 shall not be aggregated with other claims for purposes of the preceding
sentence).

          (c)  Notwithstanding anything to the contrary set forth herein,
nothing in this Agreement shall limit the liability of any Party in connection
with any claims, actions or suits based upon fraud, willful misconduct or
intentional misrepresentation.

     8.2  INDEMNIFICATION BY BUYER.

     Buyer will indemnify and hold harmless Seller and Seller's officers,
directors, agents and employees (hereinafter referred individually as an
"Seller Indemnified Person" and collectively

                                      -33-

<PAGE>   34

as "Seller Indemnified Persons") from and against, and will pay to indemnify
Seller Indemnified Persons the amount of any Damages (as such term is defined
in Section 8.1, substituting the term "Seller" for "Buyer" in such definition)
arising out of misrepresentation or breach of or default in connection with any
of the representations, warranties, covenants and agreements given or made by
the Buyer in this Agreement.

     8.3  CLAIMS GENERALLY.

     (a)  If at any time an indemnified party is entitled to indemnification
under Article VIII or shall become aware of any state of facts that have
resulted or may result in a claim for Damages, and if Buyer is the Indemnified
Person and the Escrow Amount is still being held by the Escrow Agent pursuant
to the Escrow Agreement, the indemnified party shall give written notice to
Seller pursuant to and otherwise follow the procedures set forth in the Escrow
Agreement. If at any time an Indemnified Person is entitled to indemnification
under Article VIII or shall become aware of any state of facts that have
resulted or may result in a claim other than against the Escrow Amount, the
Indemnified Person shall then follow the procedures set forth in (b) through
(e) below.

     (b)  Upon becoming aware of any state of facts that have resulted or may
result in a claim, the Indemnified Person shall promptly give written notice (a
"Notice of Claim") to the party obligated to provide indemnification (the
"Indemnitor") of the discovery of such potential or actual claim. The Notice of
Claim shall set forth (A) a description of the nature of the potential or
actual claim, specifying in reasonable detail the nature of the
misrepresentation, breach of warranty or other claim to which such item is
related, and (B) the total amount of Damages anticipated (if known) specifying
in reasonable detail the individual items of such Damages included in the
amount so stated (including any costs or expenses which have been or may be
reasonably incurred in connection therewith), the date each such item was paid,
or properly accrued or arose. Except for a failure to deliver a Notice of Claim
within the applicable survival periods as provided under Section 7.2, the
Indemnified Person's failure to give prompt notice shall constitute a defense
(in whole or in part) to any claim by the Indemnified Person against the
Indemnitor for indemnification only to the extent that such failure shall have
caused or materially increased such liability or materially and adversely
affected the ability of the Indemnitor to defend against or reduce its
liability.

     (c)  The Indemnitor shall accept or reject any claim as to which a Notice
of Claim is sent by the Indemnified Person by giving written notice of such
acceptance or rejection (the "Indemnitor Notice") to the Indemnified Person
within thirty (30) days after the date of receipt of the Notice of Claim.
Failure of the Indemnitor to reject a claim within thirty (30) days of receipt
of the Notice of Claim shall be conclusive evidence of the Indemnitor's
acceptance of its responsibility to indemnify the Indemnified Person against
such Damages in respect of the claim.

     (d)  If the Indemnitor elects to reject the claim, the Indemnitor Notice
shall set forth a brief description of the nature of the basis for the
rejection of such claim, without limiting Indemnitor's rights to identify
further bases for rejecting such claim in the future.

                                      -34-

<PAGE>   35

     (e)  If the Indemnitor elects to accept the claim or if the Indemnitor and
the Indemnified Person should otherwise agree on the resolution of the claim, a
memorandum setting forth such agreement shall be prepared and signed by both
parties.

     (f)  The Parties agree that any controversy or claim arising out of or
relating to this Agreement or breach thereof shall be settled by arbitration in
accordance with the National Rules of the American Arbitration Association (the
"AAA") in Baltimore, Maryland. Each Party shall appoint an arbitrator who has
expertise in the interpretation of commercial contracts and these two
arbitrators shall select a third neutral arbitrator from the AAA's commercial
panel who also shall have expertise in the interpretation of commercial
contracts. In reaching their decision, the arbitrators shall have no authority
to change or modify any provision of this Agreement. Such arbitrators shall act
as the administrators and exclusive arbitrators with respect to all claims.
Each Party shall be responsible for its costs and the costs of its selected
arbitrator, and the costs of the AAA and the third arbitrator shall be split
evenly between Seller, on the one hand, and Buyer, on the other hand unless the
arbitrator determines otherwise. The decision of the arbitrators as to the
validity of the claim and amount of Damages in respect to such claim shall be
binding and conclusive upon the Parties and may be entered in any court having
jurisdiction thereover, and if applicable, shall be provided to the Escrow
Agent for purposes of the Escrow Agreement.

     8.4  THIRD-PARTY CLAIMS.

     In addition to any other procedural requirements set forth in Section 8.3,
if the Buyer becomes aware of a third-party claim, Buyer shall promptly notify
the Seller of such claim, and the Seller shall be entitled, at their expense,
to participate in any defense of such claim. Buyer shall have the right to
settle any such claim only with the prior written consent of the Seller, which
consent shall not be unreasonably withheld. For purposes of the preceding
sentence, it shall be reasonable for the Seller to withhold such consent if the
terms of any such settlement do not include the full release of Seller with
respect to such claim. Following notice of any claim, Buyer shall notify the
Seller of any discussions, negotiations or other material developments
affecting such claim and, to the extent commercially reasonable, permit the
Seller to participate in any such discussions or negotiations.

                                   ARTICLE IX
                                 MISCELLANEOUS

     9.1  CERTAIN DEFINITIONS.

entities means any material event, change, condition or effect related to the
financial condition, properties, assets (including intangible assets),
liabilities, business, operations, results of operations or business prospects
of such entity or group of entities. In this Agreement, any reference to a
"MATERIAL ADVERSE EFFECT" with

                                      -35-

respect to any entity or group of entities means any event, change or effect
that, either individually or in the aggregate, is materially adverse to the
financial condition, properties, assets, liabilities, business, operations,

established and administered in accordance with generally accepted accounting
principles.

Schedule 2 hereto, each of the Companies has good and marketable title to all
of its assets and properties, free and clear of any liens, pledges, security
interests, claims, encumbrances or other restrictions of any kind (collectively,

              Schedule 2 hereto is a true, correct and complete list of all
              patents, trademarks, service marks, trade names, brand names,
              franchises, technology, areas of know-how and processes, and
              registered copyrights, and any applications for any of the
              foregoing (collectively, the "Intellectual Property") of any
              kind in which any of the Companies has an interest or which is
              otherwise used in, the business of, such Company. Part 2.9 of
              Schedule 2 hereto also contains a true, correct and complete
              list of all licenses or agreements that materially affect the
              rights of the Companies to any of the Intellectual Property or
              any trade secret material of the Companies (the "Intellectual
              Property Licenses").

                       (ii) Except as set forth in Part 2.9 of Schedule 2,
              the Companies are the sole and exclusive owners, free and
              clear of all Liens, and have all right, title and interest in
              all of the Intellectual Property. With respect to any
              Intellectual Property or trade secret necessary to conduct its
              business, each of the Companies owns or has the right to use
              such Intellectual Property or trade secret in its business.
              Each of the Companies has the right to use all Intellectual
              Property necessary to conduct the business of such of the
              Companies as now being conducted and as proposed to be
              conducted by such of the Companies.

                       (iii) Each of the Intellectual Property Licenses is
              in full force and effect and constitutes a legal, valid,
              binding and enforceable obligation in accordance with its
              terms against each of the Companies party thereto, except as
              the enforceability thereof may be limited by bankruptcy,
              insolvency, moratorium or other similar laws affecting the
              enforceability of creditors' rights in general or by general
              principles of equity and, to the best knowledge of the
              Company, each other Person party thereto. Each of the
              Companies has performed all obligations imposed upon it under
              each of the Intellectual Property Licenses to which it is a
              party. None of the Companies nor, to the best knowledge of the
              Company, any other party thereto is in default thereunder,
              nor, to the best knowledge of the Company, is there any event
              that with notice or lapse of time, or both, would constitute a
              default thereunder. None of the Companies has received any
              notice that any other party to any of the Intellectual
              Property Licenses intends to cancel, terminate or refuse to
              renew the same or to exercise or decline to exercise any
              option or other right thereunder. No licenses, sublicenses,
              covenants or agreements have been granted or entered into by
              any of the Companies in respect

                                       8
<PAGE>   10

              of any of the Intellectual Property or any trade secret material
              of any of the Companies, except the Intellectual Property
              Licenses. To the best knowledge of the Company, no director,
              officer, stockholder, employee or other Affiliate of the Company
              owns, directly or indirectly, in whole or in part, any of the
              Intellectual Property or any trade secret material of any of the
              Companies. To the best knowledge of the Company, none of the
              officers, employees, consultants, distributors, agents,
              representatives or advisors of any of the Companies have entered
              into any agreement relating to such of the Companies' business
              regarding know-how, trade secrets, assignment of rights in
              inventions, or prohibition or restriction of competition or
              solicitation of customers, or any other similar restrictive
              agreement or covenant, whether written or oral, with any Person
              other than the Companies.

                       (iv) None of the Companies have disclosed other than
              in the ordinary course of business consistent with past
              practice any proprietary information relating to the
              Intellectual Property or the Intellectual Property Licenses to
              any person other than the Investors and the Companies'
              employees, consultants, accountants, lawyers and other
              advisors. Each of the Companies has at all times maintained
              reasonable procedures to protect and have enforced all trade
              secrets of such Company. Each of the Companies has disclosed
              trade secrets to other Persons solely as required for the
              conduct of such Company's business and solely under
              nondisclosure agreements that are enforceable by such Company.
              None of the Companies is under any contractual or other
              obligation to disclose any proprietary information relating to
              the Intellectual Property, any trade secret material of any of
              the Companies or the Intellectual Property Licenses, nor, to
              the best knowledge of the Company, is any other party to the
              Intellectual Property Licenses under any such obligation to
              disclose proprietary information included in or relating to
              Intellectual Property, any trade secret material to any of the
              Companies or the Intellectual Property Licenses to any Person,
              and no event has taken place, including the execution and
              delivery of this Agreement and the transactions contemplated
              hereby or any related change in the business activities of any
              of the Companies, that would give rise to such obligation.

                       (v) The consummation of the transactions contemplated
              hereby will not alter or impair the rights of any of the
              Companies to any of the Intellectual Property, any trade
              secret material to any of the Companies, or under any of the
              Intellectual Property Licenses.

                        (b) (i) No claim with respect to the Intellectual
      Property, any trade secret material to any of the Companies, or any
      Intellectual Property License which would materially adversely affect
      the ability of any of the Companies to conduct its business as
      presently conducted and as proposed to be conducted in accordance with
      the Business Plan is currently pending or, to the best knowledge of the
      Company, has been asserted, or threatened by any Person, nor does the
      Company know of any grounds for any claim

      against any of the Companies, (A) to the effect that any operation or
      activity of any of the Companies presently occurring or contemplated,
      including, inter alia, the manufacture, use or sale of any software,
      product, device, instrument, or other material made or used according to

                  any activity of any Company.

                        (c) (i) The patents and patent applications listed in
      Part 2.9 of Schedule 2 hereto (the "Patents and Applications") as part
      of the Intellectual Property, to the best knowledge of the Company,
      have been properly prepared and filed on behalf of each of the
      Companies named therein and are being diligently pursued by the
      Companies. The inventions described in the Patents and Applications are
      assigned or licensed to the Company or a Subsidiary and no other entity
      or individual has any right or claim in any of the inventions, Patents
      and Applications or any patents to be issued therefrom. None of the
      Companies is aware of any material defects in any of the Patents and
      Applications which would cause any of them to be held invalid or
      unenforceable. Each of the Companies named in any of the Patents and
      Applications has filed in the Patents and Applications to which it is a
      party all relevant and noncumulative prior art of which it is aware.

                  proceeding, pending or threatened, that would affect the
                  validity of any patent issued pursuant thereto.

                           (iii) Except in connection with the prosecution of
                  the patent applications listed on Part 2.9 of Schedule 2
                  hereto, there are no pending judicial or governmental
                  proceedings, including but not limited to interferences and
                  oppositions, relating to any of the Patents and Applications
                  or any other proprietary information to which the Company or
                  any Subsidiary is a party or by which any property (such
                  term "property" specifically to include rights pursuant to
                  licenses or options or other rights to acquire licenses) of
                  the Company or any Subsidiary is subject, and no such
                  proceedings are threatened or contemplated by Governmental
                  Authorities or other Persons.

the affairs of any of the Companies. Except as set forth in Part 2.11 of
Schedule 2, the employment of each officer and key employee of each of the

2, neither the Company nor any entity that would be deemed a "single employer"

              Schedule 2:

                   (i) in all material respects each Plan complies and has been
              maintained and administered at all times in accordance with its
              terms and all applicable laws, rules and regulations, including,
              without limitation, ERISA and the Code and any trust maintained
              pursuant thereto is exempt from federal income taxation under
              Section 501 of the Code and nothing has occurred or is expected

              cause the loss of such exemption or the imposition of any
              material penalty or tax liability;

                   (ii) no claim, lawsuit, arbitration or other action has been
              threatened, asserted, instituted, or anticipated against the
              Plans (other than non-material routine claims for benefits, and
              appeals of such claims), any trustee or fiduciaries thereof, the
              Company, any ERISA Affiliate, any director, officer, or employee
              thereof, or any of the assets of any trust of the Plans;

                   (iii) no "prohibited transaction," within the meaning of
              Section 4975 of the Code and Section 406 of ERISA, has occurred
              or is expected to occur with respect to the Plan (and the
              consummation of the transactions contemplated by this Agreement
              will not constitute or directly or indirectly result in a
              "prohibited transaction")

                         (c) The consummation of the transactions contemplated
         by this Agreement will not give rise to any liability, including,
         without limitation, liability for severance pay, unemployment
         compensation, or termination pay, or accelerate the time of payment
         or vesting or increase the amount of compensation or benefits due
         to any employee, director, shareholder, or beneficiary of the
         Company (whether current, former, or retired) or their
         beneficiaries solely by reason of such transactions. No amounts
         payable by the Companies under any Plan will fail to be deductible
         for U.S. federal income tax purposes by virtue of Section 280G or
         162(m) of the Code. Neither the Company nor any ERISA Affiliate
         maintains, contributes to, or in any way provides for any benefits
         of any kind whatsoever (other than under Section 4980B of the
         Code, the Federal Social Security Act, or a plan qualified under
         Section 401(a) of the Code, or as otherwise required by applicable
         law) to any current or future retiree or terminee. Except as
         disclosed in the Financial Statements, neither the Company nor any
         ERISA Affiliate has any material unfunded, uninsured liabilities
         pursuant to any Plan that is not intended to be qualified under
         Section 401(a) of the Code.

                  2.13 Litigation. Except as set forth in Part 2.13 of Schedule
2 hereto, there is no action, suit, proceeding, investigation or governmental

the Company, threatened against any of the

                                       12
<PAGE>   14

Companies, or affecting any of the properties or assets of any of the Companies
(including, without limitation, any of its Permits) which individually or in
the aggregate could have a material adverse effect on the Condition of the
Companies, taken as a whole, nor, to the best knowledge of the Company, is
there any basis for any such Action. To the best knowledge of the Company after
due inquiry, there is no Action against any director, officer or employee of
any of the Companies in connection with the business of any of the Companies
which, in the event of an adverse judgment against any such Person, could have
a material adverse effect on the Condition of the Companies, taken as a whole,
nor, to the best knowledge of the Company, is there any basis for any such
Action. The foregoing includes, without limitation, any Action pending or, to
the Company's best knowledge, threatened (or any basis therefor known to the
Company) involving the prior employment of any employees of any of the
Companies, their use in connection with the business of any of the Companies of
any information or techniques allegedly proprietary to any of their former
employers, or their obligations under any agreements with prior employers. None
of the Companies nor any of their respective assets or properties, nor, in
connection with its business, to the best knowledge of the Company, any
stockholder, director, officer or employee of any of the Companies, is subject
to any order, judgment, writ, injunction, decree, ruling or decision
(collectively, an "Order") of any Governmental Authority which is material to
the Condition of the Companies, taken as a whole. There is no Action by any of
the Companies currently pending or which any of the Companies intends to
initiate which is material to the Condition of the Companies, taken as a whole.

                  2.14 Compliance with Laws; Permits. None of the Companies has
violated or failed to comply with any statute, law, ordinance, rule,
regulation or policy of any Governmental Authority (collectively, "Laws") to
which it or any of its properties or assets is subject, except where the
failure to so comply could not reasonably be expected to have a material
adverse effect on the Condition of any of the Companies. Each of the Companies
has all permits, licenses, orders, certificates, authorizations and approvals
of any Governmental Authority (collectively, the "Permits") that are material
to the conduct of its business as presently conducted and as proposed to be
conducted consistent with the Business Plan. All such Permits are in full force
and effect, and to the best knowledge of the Company no violations or notices
of failure to comply have been issued or recorded in respect of any such
Permits. None of the Companies has any knowledge of any reason why such Permits
may be revoked or suspended. All applications, reports, notices and other
documents required to be filed by the Companies with all Governmental
Authorities have been timely filed and are complete and correct in all material
respects as filed or as amended prior to the date hereof, except where the
failure to so file could not reasonably be expected to have a material adverse
effect on the Condition of any of the Companies. With respect to any required
Permits, applications for which are either pending or contemplated to be made
pursuant to the business strategy of the Companies, the Company does not know
of any reason why such Permits should not be approved and granted by the
appropriate Governmental Authority. None of the Companies nor, to the best
knowledge of the Company, any of their respective officers or agents has made
any illegal or improper payments to, or provided any illegal or improper
inducement for, any governmental official or other Person in an attempt to
influence any such Person to take or to refrain from taking any action relating
to any of the Companies. After due inquiry, the Company has no knowledge that
during the past five

                                       13
<PAGE>   15

years, any officer or key employee of the Company has been (a) arrested for or
convicted of a crime (other than minor traffic violations), (b) adjudged a
bankrupt or (c) been an officer or director of a company that has been adjudged
a bankrupt.

                  2.15 Taxes. All federal, state, city, county, local and
foreign income, franchise, sales, use and value added tax returns and reports,
and all other tax returns and reports required to be filed by any Company in
those or in any other jurisdiction (collectively, "Returns") have been timely
filed other than such failures which are not material to the Condition of the
Companies taken as a whole. All such Returns are true, correct and complete in
all material respects. All taxes, assessments, fees, interest, penalties and
other charges with respect thereto (collectively, "Taxes") due or claimed to be
due from any of the Companies have been paid except to the extent reserved
against on the Financial Statements. Except as set forth in Part 2.15 of
Schedule 2 hereto, no income tax return of any of the Companies has been audited
by the applicable Governmental Authority, no controversy with respect to taxes
of any type is pending or, to the knowledge of the Company, threatened, and
there are in effect no waivers of the applicable statute of limitations for
Taxes in any jurisdiction for any of the Companies for any period. Neither the
Company nor any of its stockholders has ever filed an election pursuant to
Section 1362 of the Code, that the Company be taxed as an S Corporation.

                  2.16 Books and Records. The books of account, ledgers and
records of each of the Companies accurately and completely reflect in all
material respects all information relating to its business, the nature,
acquisition, maintenance, location and collection of its assets, and the
nature of all transactions giving rise to its obligations or accounts
receivable. The minute books of each of the Companies fully set forth all
action taken by the Board of Directors, stockholders and, if any, executive
board (or other committee thereof) of each such Company.

                  2.17 Environmental Matters. The business, assets and
properties of each of the Companies are and have been operated and maintained
in compliance with all applicable federal, state, city, county and local
environmental protection laws and regulations (collectively, the "Environmental
Laws"), except where the failure to so comply could not reasonably be expected
to have a material adverse effect on the Condition of any such Company. No event
has occurred which, with or without the passage of time or the giving of notice,
or both, would constitute a non-compliance by any of the Companies with, or a
violation by any of the Companies of, the Environmental Laws, except for
violations which could not reasonably be expected to have a material adverse
effect on the Condition of any such Company. None of the Companies nor any of
their respective predecessor companies has caused or permitted to exist, as a
result of an intentional or unintentional act or omission by any such Company,
any of their respective predecessor companies or, to the best knowledge of the
Company, by any contractor or supplier of any of their raw materials, a
disposal, discharge or release of solid wastes, pollutants or hazardous
substances, on or from any site which currently is or formerly was owned,
leased, occupied or used by any of the Companies or any predecessor company, or,
to the best knowledge of the Company, any contractor or supplier of any of their
raw materials, except where such disposal, discharge or release was in
compliance with the Environmental Laws. Part

with any past or present Principal Owner of the Company or with any of his or
its Affiliates, associates or relatives. Except for employment arrangements
with its employees, and except as provided in the footnotes to the Audited
Financial Statements, none of the Companies has any obligation to or, to the
best knowledge of the Company, claim against any past or present Principal
Owner of the Company, or any of his or its Affiliates, associates or relatives,
and no such Person has any obligation to or claim against any of the Companies.
All products, services or benefits provided to any of the Companies by any such
Person, or provided by any of the Companies to any such Person, are set forth
on Part 2.18 of Schedule 2 and are provided at a charge equal to the fair
market value of such products, services or benefits.

the Securities Act of 1933, as amended (the "Securities Act"), relating to any
securities of any of the Companies or to participate in any such registration
statement.

                  2.20 No Brokers or Finders. Except for the agreement between
the Company and Lehman Brothers attached hereto as Exhibit H (including a
schedule of the types and amounts of fees payable thereunder), none of the
Companies nor any of their respective Affiliates has entered or will enter into
any agreement pursuant to which any of the Companies or any Investor will be
liable, as a result of the transactions contemplated by this Agreement or any
of the Investment Documents, for any claim of any person for any commission,
fee or other compensation as finder or broker.

                  2.21 Investment Company Act. Neither the Company nor any of

Subsidiaries directly or indirectly controlled by or acting on behalf of any
Person which is an "Investment Company" within the meaning of the Investment
Company Act of 1940, as amended.

                  2.22 Use of Proceeds. The Company will use the proceeds from
the sale of the Securities to the Investors solely for general corporate
purposes arising in the ordinary course of business, to repay certain
indebtedness as detailed in Part 2.22 of Schedule 1 hereto and for

                                       15
<PAGE>   17

working capital and growth, modernization and expansion. The Company may also
use such proceeds for research and development.

                  2.23 Business Plan. The business plan of the Company dated
July 1999 (the "Business Plan"), including the projections contained therein,
was prepared by the senior management of the Company, is based on assumptions
which are considered by senior management of the Company to be reasonable, and
reflects management's reasonable best judgment based on present circumstances
of the most likely set of conditions and courses of action and most likely
financial condition and results of operations, for the period(s) reflected
therein. The Company is not aware of any fact or condition which could
reasonably be expected to result in the Company not achieving the results
described in such business plan; however, the Company makes no assurance that
the Business Plan will reflect actual results.

                  2.24 Employee Non-Disclosure and Proprietary Information and
Inventions Agreements. Each employee and officer of each of the Companies who

reasonable efforts to prevent any such violation.

Company (including without limitation all software, hardware, workstations and
related components, automated devices, embedded chips and other date sensitive
equipment such as security systems, alarms, elevators and HVAC systems) are
Year 2000 Compliant. The term "Year 2000 Compliant" as used herein means that

suppliers, service providers, subcontractors, processors, converters, shippers,
warehousemen, outsourcers, data processors, regulatory agencies and banks)
whether or not they have achieved Year 2000 Compliance. The Company has
inquired of all such third parties whose lack of Year 2000 Compliance would be
materially adverse to the Company, and all such third parties have represented
that they are Year 2000 Compliant.
