                                    RECITALS

         A. Parent, Merger Sub and the Company intend to effect a merger (the

amended (the "Code"). For accounting purposes, it is intended that the Merger be
treated as a "pooling of interests."

         C. The Board of Directors of the Company has unanimously (i) determined
that the Merger is fair to, and in the best interests of, the Company and its
stockholders, (ii) approved this Agreement, the Escrow Agreement, the Merger and

         D. The respective Boards of Directors of Parent and Merger Sub have
approved this Agreement, the Escrow Agreement and the Merger.

         E. Concurrently with the execution of this Agreement, and as a
condition and inducement to Parent's and Merger Sub's willingness to enter into
this Agreement, each of the affiliates of the Company listed on Schedule 2.28 of
the Company Schedules hereto is entering into an Affiliate Agreement
substantially in the form attached hereto as Exhibit A.

         F. Concurrently with the execution of this Agreement, each of the
affiliates of Parent listed on Schedule 3.7 of the Parent Schedules is entering
into an Affiliate Agreement substantially in the form attached hereto as Exhibit
B

         (i) this Agreement, including Sections 1.6(c) and 1.6(h) hereof, and

         and be converted automatically into the right to receive from Parent
         that number of shares of Parent Common Stock equal to the Exchange
         Ratio. For purposes of this Agreement, the following definitions shall
         apply:

                           (i) "Exchange Ratio" shall mean the quotient obtained
                  by dividing (x) the Merger Consideration Share Number by (y)
                  the Fully Diluted Company Share Number, rounded down to the
                  nearest .0000001, which quotient is 0.0974021;

                           (ii) the "Merger Consideration Share Number" is
                  6,573,436 shares of Parent Common Stock, which was determined
                  by dividing an amount equal to the Merger Consideration by the
                  Designated Parent Stock Price (as defined below);


                                       3
<PAGE>   8
                           (iii) the "Designated Parent Stock Price" is
                  7.1499900, which is the average closing price per share of
                  Parent's common stock on the Nasdaq National Market for the
                  ten (10) trading day period ending on the trading day two (2)
                  trading days immediately prior to the execution of this
                  Agreement, rounded down to the nearest .0000001;

                           (iv) the "Fully Diluted Company Share Number" means
                  the sum of (A) the aggregate number of shares of Company
                  Common Stock issued and outstanding immediately prior to the
                  Effective Time, and (B) the aggregate number of shares of
                  Company Common Stock issuable under, or otherwise subject to,
                  any Purchase Rights outstanding immediately prior to the
                  Effective Time (including any Purchase Rights that are
                  unvested or are otherwise not then exercisable and including
                  all shares of Company Common Stock issued or issuable upon
                  exercise, conversion or exchange of all unvested and vested
                  Company Options which are not exercised, converted, exchanged
                  or expired immediately prior to the Effective Time).

                  (b) Stock Restrictions. If any shares of Company Common Stock
         issued and outstanding immediately prior to the Effective Time are
         unvested or subject to a risk of forfeiture or other condition (other
         than any right of repurchase) under any applicable restricted stock
         purchase agreement or other agreement with the Company, then the shares
         of Parent Common Stock issued in exchange for such shares of Company
         Common Stock will also be unvested and subject to the same risk of
         forfeiture or other condition (other than any right of repurchase), and
         the certificates representing such shares of Parent Common Stock may
         accordingly be marked with appropriate legends in the discretion of
         Parent.

                  (c) Escrows. A number of shares of Parent Common Stock (the
         "Escrow Shares") determined by dividing an aggregate amount equal to

         reserved for any claims of the Indemnified Parties under Section
         8.3(a)(i)(F) and $2,443,821 is being reserved for any other indemnity
         claim that may arise under Section 8.3 of this Agreement) by the
         Designated Parent Stock Price (none of which Escrow Shares shall be
         unvested, subject to any right of repurchase, risk of forfeiture or
         other condition in favor of the Company or the Surviving Corporation)
         shall be held in escrow pursuant to the Escrow Agreement to be
         available as the exclusive (other than with respect to claims of fraud
         or intentional misrepresentation) source to reimburse Parent and its
         Affiliates (including the Surviving Corporation) for any Losses (as
         defined in Section 8.3(a) hereof) incurred in connection with this
         Agreement and the transactions contemplated hereby. The Escrow Shares
         will be withheld on a pro rata basis among the holders of Company

         each holder of Company Common Stock will be set forth in the Escrow
         Schedules as provided in Section 8.2(a). The delivery of the Escrow
         Shares will be made on behalf of the holders of Company Common Stock in
         accordance with the provisions hereof, with the same force and effect
         as if such shares had been delivered by Merger Sub directly to such
         holders and subsequently delivered by such holders to the Escrow Agent
         (as defined in Section 8.2(a)).

                  (d) Cancellation of Parent-Owned and Company-Owned Stock. At
         the Effective Time, by virtue of the Merger and without any action on
         the part of Merger Sub, the Company, the holders of any shares of
         Company Common Stock, or the holders of any capital stock of Merger
         Sub, each share of Company Common Stock owned by Merger Sub, Parent,
         the Company or any direct or indirect wholly-owned subsidiary of Parent
         immediately prior to the Effective Time shall be canceled and
         extinguished without any conversion thereof and no consideration shall
         be delivered in exchange therefor.

                  (e) Stock Options. At the Effective Time, the Company's
         "Planning Technologies, Inc. Stock Incentive Plan," as amended to date
         (the "Option Plan"), and all options to purchase Company Common Stock
         (as defined in Section 2.3(a)) then outstanding under the Option Plan,
         shall be assumed by Parent in accordance with the following provisions:

                           (i) At the Effective Time, each outstanding option to
                  purchase shares of Company Common Stock issued under the
                  Option Plan (each a "Company Option"), whether vested or
                  unvested, shall be, in connection with the Merger, assumed by
                  Parent. Parent and the Company will take all action necessary
                  to cause the assumption by Parent as of the Effective Time of
                  the Option Plan and all of the Company Options set forth on
                  Schedule 2.3(b) with the consent of Parent and, in each case,
                  outstanding as of the Effective Time. The Company will take
                  all corporate action necessary to effect, without the consent
                  or cooperation of the holders of Company Options, such
                  assumption by Parent and the conversion of the Company Options
                  into options to purchase shares of Parent Common Stock as set
                  forth herein. Each Company Option so assumed by Parent under
                  this Agreement shall continue to have, and be subject to, the
                  same terms and conditions set forth in the Option Plan and/or
                  as provided in the respective option agreements governing such
                  Company Option immediately prior to the Effective Time, except
                  that (A) such Company Option shall be exercisable for that
                  number of whole shares of Parent Common Stock equal to the
                  product of the number of shares of Company Common Stock that
                  were issuable upon exercise of such Company Option immediately
                  prior to the Effective Time multiplied by the Exchange Ratio,
                  rounded down (in the case of Company Options granted under the
                  Option Plan) to the nearest whole number of shares of Parent
                  Common Stock and (B) the per share exercise price for the
                  shares of Parent Common Stock issuable upon exercise of such
                  assumed Company Option shall be equal to the quotient
                  determined by dividing the exercise price per share of Company
                  Common Stock at which such Company Option was exercisable
                  immediately prior to the Effective Time by the Exchange Ratio,
                  rounded up to the nearest whole cent.

                           (ii) It is the intention of the parties that the
                  Company Options assumed by Parent pursuant to this Section
                  1.6(e) qualify following the Effective Time as incentive stock
                  options as defined in Section 422 of the Code to the extent
                  the Company Options qualified as incentive stock options
                  immediately prior to the Effective Time.

                           (iii) Promptly following the Effective Time, Parent
                  will issue to each holder of an outstanding (unexpired and
                  unexercised) Company Option a document evidencing the
                  foregoing assumption of such Company Option by Parent.

                           (iv) Parent will reserve sufficient shares of Parent
                  Common Stock for issuance pursuant to this Section 1.6(e).

                           (v) No new options shall be issued pursuant to the
                  Option Plan. New options, if any, would be issued pursuant to
                  the Parent's existing stock option plan.

                  (f) Capital Stock of Merger Sub. At the Effective Time, by
         virtue of the Merger and without any action on the part of Merger Sub,
         the Company, the holders of any shares of Company Common Stock or the
         holders of any capital stock of Merger Sub, each share of Common Stock
         of Merger Sub issued and outstanding immediately prior to the Effective
         Time shall be converted into and become one validly issued, fully paid
         and nonassessable share of Common Stock of the Surviving Corporation.
         Each stock certificate of Merger Sub evidencing ownership of any such
         shares shall continue to evidence ownership of such shares of capital
         stock of the Surviving Corporation.

                  (g) Adjustments. In the event of any stock split, reverse
         split, stock dividend (including any dividend or distribution of
         securities convertible into Parent Common Stock or Company Common
         Stock), reorganization, recapitalization or other like change with
         respect to Parent Common Stock or Company Common Stock occurring after
         the date hereof and prior to the Effective Time, appropriate
         adjustments will be made to the number of shares of Parent Common Stock
         issuable in exchange for shares of Company Common Stock and upon the
         exercise of Company Options.

                  (h) Fractional Shares. No fraction of a share of Parent Common
         Stock will be issued, but in lieu thereof, each holder of shares of
         Company Common Stock who would otherwise be entitled to a fraction of a
         share of Parent Common Stock (after aggregating all fractional shares
         of Parent Common Stock to be received by such holder) shall be entitled
         to receive from Parent an amount of cash (rounded to the nearest whole
         cent) equal to the product of (i) such fraction, multiplied by (ii) the
         Designated Parent Stock Price.

         1.7      SURRENDER OF CERTIFICATES.

                  (a) Exchange Agent. Prior to the Effective Time, Parent shall
         designate First Union National Bank, Charlotte, North Carolina (or if
         First Union National Bank is not willing or able to so act, another
         United States bank or trust company reasonably acceptable to the
         Company) to act as exchange agent (the "Exchange Agent") in the Merger.

                  (b) Parent to Deliver Common Stock. Promptly following the
         Closing, but in no event later than ten (10) business days following
         the Closing, Parent shall deliver to the Exchange Agent for exchange in
         accordance with this Article I, the aggregate amount of cash and the
         aggregate number of shares of Parent Common Stock payable or issuable


                                       6
<PAGE>   11
         pursuant to Section 1.6 in exchange for outstanding shares of Company
         Common Stock; provided, however, that, on behalf of the holders of
         shares of Company Common Stock, and pursuant to the Escrow Agreement
         and Section 8.2(a) hereof, Parent shall deposit the Escrow Shares with
         the Escrow Agent out of the aggregate number of shares of Parent Common
         Stock otherwise issuable pursuant to Section 1.6.

                  (c) Exchange Procedures. Promptly after the Effective Time,
         but in no event later than ten (10) business days following the
         Effective Time, the Surviving Corporation shall cause to be mailed to
         each holder of record of a certificate or certificates (the
         "Certificates") which immediately prior to the Effective Time
         represented outstanding shares of Company Common Stock whose shares
         were converted into the right to receive shares of Parent Common Stock
         from Merger Sub pursuant to Section 1.6, (i) a form of letter of
         transmittal (which shall specify that delivery shall be effected, and
         risk of loss and title to the Certificates shall pass, only upon
         delivery of the Certificates to the Exchange Agent and shall be in such
         form and have such other provisions as Parent may reasonably specify)
         and (ii) instructions for use in effecting the surrender of the
         Certificates in exchange for certificates representing shares of Parent
         Common Stock. Promptly after the Effective Time, but in no event later
         than ten (10) business days following the Effective Time, the Surviving
         Corporation shall cause to be mailed to the Company Stockholders other
         than the Signing Stockholders, notice of dissenters rights pursuant to
         Georgia Law Sections 14-2-1301, et. Seq. and a private placement
         memorandum. Upon surrender of a Certificate for cancellation to the
         Exchange Agent or to such other agent or agents as may be appointed by
         the Surviving Corporation, together with such letter of transmittal,
         duly completed and validly executed in accordance with the instructions
         thereto, and such other customary documents as may be required pursuant
         to such instructions (the "Transmittal Documents"), the holder of such
         Certificate shall be entitled to receive in exchange therefor a
         certificate representing the number of whole shares of Parent Common
         Stock (less the number of shares of Parent Common Stock to be deposited
         with the Escrow Agent on such holder's behalf pursuant to Section 1.6
         and Section 8.2(a) hereof and the Escrow Agreement), plus cash in lieu
         of fractional shares in accordance with Section 1.6, to which such
         holder is entitled pursuant to Section 1.6, and the Certificate so
         surrendered shall forthwith be canceled. At the Closing, and subject to
         and in accordance with the provisions of Section 8.2(a) hereof and the
         Escrow Agreement, Parent shall cause to be delivered to the Escrow
         Agent, on behalf of the holders of Certificates, certificates
         representing the Escrow Shares which shall be registered in the name of
         the Escrow Agent. Such shares shall be beneficially owned by the
         holders on whose behalf such shares were deposited with the Escrow
         Agent as set forth in Section 8.2(a) and the Escrow Agreement and shall
         be available to reimburse Parent as provided in Sections 8.2(a), 8.3(a)
         and the Escrow Agreement. Until so surrendered, each outstanding
         Certificate that, prior to the Effective Time, represented shares of
         Company Common Stock will be deemed from and after the Effective Time,
         for all corporate purposes, other than the payment of dividends, to
         evidence the ownership of the number of full shares of Parent Common
         Stock into which such shares of Company Common Stock shall have been so
         converted and the right to receive an amount in cash in lieu of the
         issuance of any fractional shares in accordance with Section 1.6.

                  (d) Distributions With Respect to Unexchanged Shares. No
         dividends or other distributions declared or made after the Effective
         Time with respect to Parent


                                       7
<PAGE>   12
         Common Stock with a record date after the Effective Time will be paid
         to the holder of any unsurrendered Certificate with respect to the
         shares of Parent Common Stock represented thereby until the holder of
         record of such Certificate shall surrender such Certificate. Subject to
         applicable law, following surrender of any such Certificate, there
         shall be paid to the record holder of the certificates representing
         whole shares of Parent Common Stock issued in exchange therefor,
         without interest, at the time of such surrender, the amount of
         dividends or other distributions with a record date after the Effective
         Time theretofore paid with respect to such whole shares of Parent
         Common Stock.

                  (e) Transfers of Ownership. If any certificate for shares of
         Parent Common Stock is to be issued in a name other than that in which
         the Certificate surrendered in exchange therefor is registered, it will
         be a condition of the issuance thereof that the Certificate so
         surrendered will be properly endorsed and otherwise in proper form for
         transfer and that the Person requesting such exchange will have paid to
         Parent or any agent designated by it any transfer or other taxes
         required by reason of the issuance of a certificate for shares of
         Parent Common Stock in any name other than that of the registered
         holder of the Certificate surrendered, or established to the
         satisfaction of Parent or any agent designated by it that such tax has
         been paid or is not payable.

                  (f) No Liability. Notwithstanding anything to the contrary in
         this Section 1.7, none of the Exchange Agent, Parent, the Surviving
         Corporation or any party hereto shall be liable to a holder of shares
         of Parent Common Stock or Company Common Stock for any amount properly
         paid to a public official pursuant to any applicable abandoned
         property, escheat or similar law.

         1.8      NO FURTHER OWNERSHIP RIGHTS IN COMPANY STOCK.

         All shares of Parent Common Stock issued by Parent and delivered by
Merger Sub upon the surrender for exchange of shares of Company Common Stock in
accordance with the terms hereof (including any cash paid in respect thereof)
shall be deemed to have been issued in full satisfaction of all rights
pertaining to such shares of Company Common Stock, and there shall be no further
registration of transfers on the records of the Surviving Corporation of shares
of Company Common Stock which were outstanding immediately prior to the
Effective Time. If, after the Effective Time, Certificates are presented to the
Surviving Corporation for any reason, they shall be canceled and exchanged as
provided in this Article I.

         1.9      LOST, STOLEN OR DESTROYED CERTIFICATES.

         In the event any certificates evidencing shares of Company Common Stock
shall have been lost, stolen or destroyed, the Exchange Agent shall issue in
exchange in lieu of such lost, stolen or destroyed certificates, upon the making
of an affidavit of that fact by the holder thereof, such shares of Parent Common
Stock and cash for fractional shares, if any, as may be required pursuant to
Section 1.6; provided, however, that Parent may, in its discretion and as a
condition precedent to the issuance thereof, require the owner of such lost,
stolen or destroyed certificates to deliver a bond in such sum as it may direct
as indemnity against any claim that may be made against Parent, the Surviving
Corporation or the Exchange Agent with respect to the certificates alleged to
have been lost, stolen or destroyed.

         1.10     TAX AND ACCOUNTING CONSEQUENCES.

         It is intended by the parties hereto that the Merger shall (i)
constitute a reorganization within the meaning of Section 368 of the Code (and
this Agreement is intended to constitute a plan of reorganization for purposes
of Section 368 of the Code) and (ii) qualify for accounting treatment as a
"pooling of interests."

         1.11     TAKING OF NECESSARY ACTION; FURTHER ACTION.

         If, at any time after the Effective Time, any such further action is
necessary or desirable to carry out the purposes of this Agreement and to vest
the Surviving Corporation with full right, title and possession to all assets,
property, rights, privileges, powers and franchises of the Company and Merger
Sub, the officers and directors of the Company and Merger Sub are fully
authorized in the name of their respective corporations or otherwise to take,
and will take, all such lawful and necessary action.

         1.12     PARENT TRADING POLICY.

         With respect to any shares of Parent held by any Person who serves as
an officer, director or employee of Parent or any subsidiary or Affiliate of
Parent, such shares shall be subject to the trading restrictions set forth in
Parent's Company Policy Regarding Insider Trading.

                                   ARTICLE II

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

         For purposes of this Agreement, any reference to "the knowledge" of the
Company shall mean the actual awareness of the particular fact or other matter
by any of the senior executive officers of the Company. Except as disclosed on
the written disclosure schedule delivered by the Company to Parent concurrently
with the execution of this Agreement (the "Company Schedules"), the Company
hereby represents and warrants to each of Parent and Merger Sub as follows:

         2.1      ORGANIZATION OF THE COMPANY.

         The Company is a corporation duly organized, validly existing and in
good standing under the laws of the State of Georgia. The Company has the
corporate power to own, lease and operate its properties and to carry on its
business as now being conducted. Except as set forth on Schedule 2.1 of the
Company Schedules, the Company is duly qualified or licensed to do business and
is in good standing as a foreign corporation in each jurisdiction in which the
failure to be so qualified or licensed has had or could be reasonably expected
to have a Material Adverse Effect (as defined below) on the Company. For
purposes of this Agreement, a "Material Adverse Effect" shall mean, with respect
to Parent on the one hand and the Company on the other hand, the result of one
or more events, occurrences, changes or effects which, individually or in the
aggregate, has had or could be reasonably expected to have a material adverse
effect or impact on the business, assets (including intangible assets), results
of operations or financial condition of such party and its subsidiaries, taken
as a whole, or on such party's ability to consummate the transactions
contemplated hereby; provided, however, changes in economic conditions generally
or changes in the industry in which the Company or Parent, as the


                                       9
<PAGE>   14
case may be, competes shall not constitute a "Material Adverse Effect." The
Company has delivered a true and correct copy of its Articles of Incorporation
and Bylaws, each as amended to date, to Parent.

         2.2      SUBSIDIARIES.

         The Company does not directly or indirectly own any equity or similar
interest in, or any interest convertible into or exchangeable or exercisable
for, any equity or similar interest in, any Person (as defined in Section 10.3
below).

         2.3      COMPANY CAPITAL STRUCTURE.

                  (a) The authorized capital stock of the Company consists of
         (i) 100,000,000 shares of Company Common Stock, of which 64,882,729
         shares are issued and outstanding and (ii) 10,000,000 shares of Company
         Series A Preferred Stock, of which no shares are issued and
         outstanding. No shares of Company Common Stock are held in the
         Company's treasury. The Company Common Stock is held of record by the
         Persons, with the addresses of record and in the amounts set forth on
         Schedule 2.3(a) of the Company Schedules. Schedule 2.3(a) of the
         Company Schedules also indicates for each Company Stockholder whether
         any shares of Company Common Stock held by such stockholder are subject
         to a repurchase right in favor of the Company, the lapsing schedule for
         any such restricted shares, including the extent to which any such
         repurchase right has lapsed as of the date of this Agreement and
         whether (and to what extent) the lapsing will be accelerated by the
         transactions contemplated by this Agreement. All outstanding shares of
         Company Common Stock are duly authorized, validly issued, fully paid
         and non-assessable and not subject to preemptive rights created by
         statute, the Articles of Incorporation or Bylaws of the Company or any
         agreement to which the Company is a party or by which it is bound. All
         issued and outstanding shares of Company Common Stock have been
         offered, sold and delivered by the Company in compliance with
         applicable federal and state securities laws. There are no outstanding
         shares of Company Common Stock other than as set forth on Schedule
         2.3(a) of the Company Schedules. Except as set forth on Schedule 2.3(a)
         of the Company Schedules, the Company has not declared any dividends
         which remain unpaid.

                  (b) The Company has reserved 6,500,000 shares of Company
         Common Stock under its employee stock option plans. Schedule 2.3(b) of
         the Company Schedules sets forth each outstanding Company Option,
         including the name of the holder of such option, the domicile address
         of such holder, an indication of whether such holder is an employee of
         the Company as of the date hereof, the date of grant or issuance of
         such option, the number of shares of Common Stock subject to such
         option, the exercise price of such option and the vesting schedule for
         such option, including the extent vested to the date of this Agreement
         and whether and to what extent the exercisability of such option will
         be accelerated and such option shall become exercisable as a result of
         the transactions contemplated by this Agreement. Except for the Company
         Options, and the agreements set forth on Schedule 2.3(b) of the Company
         Schedules, there are no options, warrants, calls, rights, exchangeable
         or convertible securities, commitments or agreements of any character,
         written or oral, to which the Company is a party or by which it is
         bound obligating the Company to (i) issue, deliver, sell, repurchase or
         redeem, or cause to be


                                       10
<PAGE>   15
         issued, delivered, sold, repurchased or redeemed, any Company Common
         Stock or (ii) grant, extend, accelerate the vesting of, change the

                  reason of a change in accounting method or otherwise, and will
                  not be required to make such an adjustment as a result of the
                  transactions contemplated by this Agreement other than changes
                  after the Effective Time to conform to Parent's accounting
                  methods.

                           (xvi) No material claim has been made by a Tax

                  United States and such foreign country.

                           (xviii) The Company has never been a member of a
                  group filing a consolidated federal income Tax Return (other
                  than a group the common parent of which was the Company), and
                  the Company has no liability for the Taxes of any Person
                  (other than the Company) under Treasury Regulation Section
                  1.1502-6 (or any corresponding provision of state, local or
                  foreign Tax law), as a transferee or successor, by contract,
                  or otherwise. The Company has no net operating losses or other

                           (xx) All amounts paid by the Company which have been
                  treated as deductible research and development expenses, are
                  properly deductible on the returns as filed.

                           (xxi) The Company has paid for any transfers of
                  technology, assets or services in a manner that will be
                  respected by the Internal Revenue Service under Internal
                  Revenue Code Section 482 and the Regulations thereunder, and
                  by the taxing authorities in foreign jurisdictions as arms
                  length under similar principles in those countries.

                           (xxii) The Company was a valid S corporation for the
                  tax years 1992 to 1993. The Company terminated its S

                  C corporation from that date forward.

         2.11     RESTRICTIONS ON BUSINESS ACTIVITIES.

         Except as set forth in confidentiality agreements and non-disclosure
agreements entered into in the ordinary course of business, there is no
agreement (noncompete or otherwise), judgment, injunction, order or decree to
which the Company is a party or otherwise binding upon the Company which has had
or could be reasonably expected to have the effect of prohibiting or impairing
any business practice of the Company, any acquisition of property (tangible or
intangible) by the Company or the conduct of business by the Company. Without
limiting the foregoing and except as set forth on Schedule 2.11 of the Company
Schedules, the Company has not entered into any agreement under which the
Company is restricted from selling, licensing or otherwise distributing any of
its products or services to any class of customers, in any geographic area,
during any period of time or in any segment of the market.

         2.12     TITLE TO PROPERTIES; ABSENCE OF LIENS AND ENCUMBRANCES.

                  (a) The Company does not own any real property, nor has the
         Company ever owned any real property. Schedule 2.12(a) of the Company
         Schedules sets forth a list of all real property currently leased by
         the Company, the name of the lessor and the date of the lease and each
         amendment thereto and with respect to any current lease, the aggregate
         annual rent. All such current leases are in full force and effect, are
         valid and effective in accordance with their respective terms, and
         there is not, under any of such leases, any existing default or event
         of default as defined in such leases (or event which with notice or
         lapse of time, or both, would constitute a default in any material
         respect). The operations of the Company on such real property, and to
         the knowledge of the Company, such real property, including
         improvements thereon, do not violate any applicable building code,
         zoning requirement, or classification, or pollution control ordinance
         or statute relating to the particular property or such operations, and
         such non-violation is not dependent, in any instance, on so-called
         non-conforming use exceptions.

                  (b) The Company has good and valid title to, or, in the case
         of leased properties and assets, valid leasehold interests in, all of
         its tangible properties and assets, real, personal and mixed, used or
         held for use in its business, free and clear of any Liens, except as
         reflected in the Company Financial Statements and such Liens, if any,
         which are not material in character, amount or extent, and which do not
         materially detract from


                                       18
<PAGE>   23
         the value, or materially interfere with the present use, of the
         property subject thereto or affected thereby.

                  (c) All facilities, machinery, equipment, fixtures, vehicles,
         and other properties owned, leased or used by the Company are (i)
         adequate for the conduct of the business of the Company as currently
         conducted and as proposed to be conducted and (ii) in good operating
         condition, subject to normal wear and tear, and reasonably fit and
         usable for the purposes for which they are being used, except where a
         failure to be in such condition has not had and could not be reasonably
         expected to have a Material Adverse Effect on the Company.

                  (d) The Company has not sold or otherwise released for
         distribution any of its customer files and other customer information
         relating to the current and former customers of the Company (the
         "Company Customer Information"). No Person other than the Company
         possesses any claims or rights with respect to use of the Company
         Customer Information.

         2.13     GOVERNMENTAL AUTHORIZATION.

         Schedule 2.13 of the Company Schedules accurately lists each consent,
license, permit, grant or other authorization issued to the Company by a
Governmental Entity (i) pursuant to which the Company currently operates or
holds any interest in any of its properties or (ii) which is required for the
operation of its business or the holding of any such interest (herein
collectively called "Company Authorizations"). The Company Authorizations are in
full force and effect and constitute all Company Authorizations required to
permit the Company to operate or conduct its business or hold any interest in
its properties or assets except for Company Authorizations the absence or
invalidity of which has not had and could not be reasonably expected to have a
Material Adverse Effect on the Company.

         2.14     INTELLECTUAL PROPERTY.

         Schedule 2.14 of the Company Schedules is a complete and correct list
of all of the material Intellectual Property used in or necessary for the
operation of the Company's business. All Intellectual Property used in or
necessary for the operation of the Company's business is owned by the Company
free and clear of all security interests or the Company has a valid license to
use the same. The Intellectual Property listed on Schedule 2.14 of the Company
Schedules constitutes all of the proprietary rights necessary and sufficient for
the lawful and efficient operation of the Company's business as presently
conducted. The Company is not infringing upon, misappropriating or otherwise
acting adversely to any Intellectual Property owned by any other person. The
Company is not in default and, to the knowledge of the Company, no third party
is in default under any license, sublicense or agreement by which the Company
holds or has given to others the right to use any Intellectual Property. The
execution and delivery of this Agreement by the Company, and the consummation of
the transactions contemplated hereby, will not cause Company to be in violation
or default under any license, sublicense or agreement by which the Company holds
or has given to others the right to use any Intellectual Property, nor entitle
any other party to any such license, sublicense or agreement to terminate or
modify such license, sublicense or agreement. For purposes of this Agreement,
"Intellectual Property" shall mean all (i) patents, patent applications, patent
disclosures and all related continuation,


                                       19

continuation in part, divisional, reissue, reexamination, utility model,

and applications for registrations, (ii) trademarks, service marks, trade dress,
logos, trade names, domain names, and corporate names ("Trademarks") and
registrations and applications for registration thereof, (iii) copyrights and

purchased by the Company from persons who are not Affiliates of the Company and
who generally offer such computer software, data and documentation for sale to
the public), (v) trade secrets, confidential and proprietary business
information, financial, marketing and business data, pricing and cost
information, databases, business and marketing plans and customer and supplier
lists, and whether patentable or unpatentable and whether or not reduced to
practice, know-how, research and development information, and business methods,
(vi) other proprietary rights relating to any of the foregoing, and (vii) copies
and tangible embodiments thereof.

         2.15     PRODUCT WARRANTIES; DEFECTS; LIABILITIES.

         Each Company Product has been in all material respects in conformity
with all applicable contractual commitments and all applicable express and
implied warranties. The Company has no liability or obligation (and to the
Company's knowledge, there is no basis for any present or future action, suit,
proceeding, hearing, investigation, charge, complaint, claim or demand against
the Company giving rise to any liability or obligation) for replacement or
repair thereof or other damages in connection therewith except liabilities or
obligations incurred in the ordinary course of business consistent with past
practice. No Company Product is subject to any guaranty, warranty, or other
indemnity beyond the applicable standard terms and conditions of sale, license
or lease or beyond that implied or imposed by applicable law. Schedule 2.15 of
the Company Schedules includes a copy of the standard terms and conditions of

         with the requirements of the Exchange Act and the rules and regulations
         of the SEC thereunder applicable to such Parent SEC Reports and (ii)
         did not at the time they were filed (or if amended or superseded by a

         filing) or will not at the time they are filed contain any untrue
         statement of a material fact or omit to state a material fact required
         to be stated therein or necessary in order to make the statements
         therein, in the light of the circumstances under which they were made,

         (including, in each case, the notes thereto) included in the final
         prospectus relating to the initial public offering of Parent Common
         Stock and in the Parent SEC Reports, including each Parent SEC Report

         respects with the published rules and regulations of the SEC with
         respect thereto; (ii) was prepared in accordance with GAAP applied on a

         and (iii) fairly presented, in all material respects, the consolidated
         financial position of Parent and its subsidiaries as at the respective

                                       34
<PAGE>   39
3.5, changes in economic conditions generally or changes in the industry in
which Parent competes shall not constitute a "Material Adverse Effect."

of any character, written or oral, to which Parent is a party or by which it is
bound obligating Parent to issue shares of its capital stock or any other
securities convertible into or evidencing the right to subscribe to shares of
its capital stock.

         3.7      AFFILIATE AGREEMENTS.

         Schedule 3.7 of the Parent Schedules sets forth those Persons who are
Affiliates of Parent (each such Person a "Parent Affiliate"). Parent has
delivered to the Company, concurrently with the execution of this Agreement,
from each Parent Affiliate, an executed Affiliate Agreement in the form attached
hereto as Exhibit B.

         3.8      POOLING OF INTERESTS.

before any governmental instrumentality or agency or arbitral body, now pending
or overtly threatened against Parent, or any of its assets or properties, (i)
that seeks to prohibit, restrain or enjoin the transactions contemplated by the
Transaction Documents or (ii) that questions the validity of the Transaction
Documents or the right of the Company to execute, deliver and perform the
Transaction Documents or to consummate the transactions contemplated thereby.

         3.11     REPRESENTATIONS COMPLETE.

         None of the representations or warranties made by Parent or Merger Sub
in this Agreement, nor any statement made in any Parent Schedule or certificate
furnished by Parent or Merger Sub pursuant to this Agreement, when taken
together, contains any untrue statement of a


                                       35
<PAGE>   40
material fact, or omits to state any material fact necessary in order to make
the statements contained herein or therein, in the light of the circumstances
under which they were made, not misleading.

                                   ARTICLE IV

                     SECURITIES ACT COMPLIANCE; REGISTRATION

         4.1      RESTRICTIONS REGARDING SECURITIES LAW MATTERS.

         Each stockholder of the Company, by virtue of the Merger and the
conversion into Parent Common Stock of the Company Common Stock held by such
stockholder, shall be bound by the following provisions:

                  (a) Such stockholder will not offer, sell, or otherwise
         dispose of any shares of Parent Common Stock except in compliance with
         the Securities Act and the rules and regulations thereunder.

                  (b) Such stockholder will not sell, transfer or otherwise
         dispose of any shares of Parent Common Stock unless (i) such sale,
         transfer or other disposition is within the limitations of and in
         compliance with Rule 144 promulgated by the SEC under the Securities
         Act and the stockholder furnishes Parent with reasonable proof of
         compliance with such Rule, (ii) in the opinion of counsel, reasonably
         satisfactory to Parent and its counsel, some other exemption from
         registration under the Securities Act is available with respect to any
         such proposed sale, transfer, or other disposition of Parent Common
         Stock or (iii) the offer and sale of Parent Common Stock is registered
         under the Securities Act.

         4.2      REGISTRATION RIGHTS.

         Each Company Stockholder acknowledges that the issuance of the Parent
Common Stock in the Merger will not be registered under the Securities Act in
reliance upon the exemption(s) from registration provided thereby, including
Section 4(2) and regulations promulgated thereunder. Each Company Stockholder
also acknowledges that the issuance of the Parent Common Stock issued in the
Merger will not be registered under the securities laws of any state.
Consequently, each Company Stockholder understands that the shares of Parent
Common Stock issued in the Merger cannot be resold unless they are registered
under the Securities Act and applicable state securities laws, or unless an
exemption from such registration requirements is available. Therefore, Parent
shall, within fifteen (15) days following the filing of Parent's Annual Report
on Form 10-K with the SEC for the year ended February 28, 2001, but no later
than May 10, 2001, file a Registration statement on Form S-3 (or any successor
form) (the "Registration Statement") to register the Parent Common Stock for
resale to the public and shall use its best efforts to cause such Registration
Statement to be declared effective as soon as commercially reasonable
thereafter; provided, however, that Parent shall not be required in connection
with this Section 4.2 to qualify as a foreign corporation or consent to service
of process in any jurisdiction. Parent shall use its best efforts to cause the
Registration Statement to remain effective until the first anniversary date of
the Effective Time or such lesser period until all shares of Parent Common Stock
have been resold to the public. Each Company Stockholder


                                       36
<PAGE>   41
understands that there will be placed on the certificates representing the
Parent Common Stock issued in the Merger as Merger Consideration a legend
stating in substance the following and each Company Stockholder understands that
Parent will refuse to permit the transfer of the Parent Common Stock out of such
Company Stockholder's name in the absence of compliance with the terms of such
legend:

         THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
         UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR UNDER ANY
         STATE SECURITIES LAWS AND MAY NOT BE SOLD, PLEDGED, TRANSFERRED,
         ASSIGNED OR OTHERWISE DISPOSED OF EXCEPT IN ACCORDANCE WITH SUCH ACT
         AND THE RULES AND REGULATIONS THEREUNDER AND IN ACCORDANCE WITH
         APPLICABLE STATE SECURITIES LAWS. RED HAT, INC. (THE "CORPORATION")
         WILL NOT TRANSFER THE SECURITIES REPRESENTED BY THIS CERTIFICATE EXCEPT
         UPON RECEIPT OF EVIDENCE SATISFACTORY TO THE CORPORATION, WHICH MAY
         INCLUDE AN OPINION OF COUNSEL, THAT THE REGISTRATION PROVISIONS OF SUCH
         ACT HAVE BEEN COMPLIED WITH OR THAT SUCH REGISTRATION IS NOT REQUIRED
         AND THAT SUCH TRANSFER WILL NOT VIOLATE ANY APPLICABLE STATE SECURITIES
         LAWS.

         In the event that, in the judgment of Parent, it is advisable, in order
to continue to be in compliance with all applicable Federal or state securities
laws, to suspend use of a prospectus included in Registration Statement due to
pending material developments or other events that have not yet been publicly
disclosed and as to which Parent believes public disclosure would be detrimental
to Parent, Parent shall notify all Company Stockholders to such effect, and,
upon receipt of such notice, each Company Stockholder shall immediately
discontinue any sales of Parent Common Stock pursuant to the Registration
Statement until such Company Stockholder has received copies of a supplemented
or amended prospectus or until such Company Stockholder is advised in writing by
Parent that the then current prospectus may be used and has received copies of
any additional or supplemental filings that are incorporated or deemed
incorporated by reference in such prospectus. Notwithstanding anything to the
contrary herein, Parent shall not exercise its rights under this Section 4.2 to
suspend sales of Parent Common Stock for a period in excess of 60 days in any
365-day period.

         4.3      REGISTRATION STATEMENT.

                  (a) In connection with the preparation of the Registration
         Statement, the Company Stockholders shall:

                           (i) provide promptly to Parent such information as
                  Parent may reasonably request and may be required for
                  inclusion in the Registration Statement, including beneficial
                  ownership of Parent Common Stock and the intended method or
                  plan of distribution;

                           (ii) promptly advise Parent if at any time prior to
                  the Effective Time they should obtain any knowledge of any
                  fact that might make it necessary or appropriate to amend or
                  supplement the Registration Statement; and

                           (iii) agree to customary indemnification and other
                  provisions in connection with the preparation and filing of
                  the Registration Statement.


                                       37
<PAGE>   42
                  (b) The information supplied by the Company Stockholders in
         writing for inclusion in the Registration Statement shall not, at (i)
         the time the Registration Statement is filed, amended, supplemented or
         declared effective and (ii) the Effective Time, contain any untrue
         statement of a material fact or omit to state any material fact
         required to be stated therein or necessary to make the statements
         therein, in light of the circumstances under which made, not
         misleading.

                  (c) In connection with the preparation of the Registration
         Statement, Parent shall:

                           (i) Prepare and file with the SEC such amendments and
         supplements to the Registration Statement and the prospectus used in
         connection therewith as may be necessary to keep the Registration
         Statement effective for the period set forth above and to comply with
         the provisions of the 1933 Act with respect to the sale or other
         disposition of the shares of Parent Common Stock covered by the
         Registration Statement.

                           (ii) Deliver to the Stockholders such numbers of
         copies of the Registration Statement, prospectus, and any amendments
         and supplements thereto, in conformity with the requirements of the
         1933 Act, such documents incorporated by reference in the Registration
         Statement and such other documents as the Stockholders reasonably
         request, in order to facilitate the public sale or other disposition of
         the Parent Common Stock. Availability of such documents on the SEC's
         Electronic Data Gathering and Retrieval System shall be deemed to
         constitute delivery pursuant to this Section 4.3(c)(ii).

                           (iii) Use its reasonable efforts to file in a timely
         manner any reports required to be filed by it under the 1933 Act and
         the Securities Exchange Act of 1934, as amended (the "1933 Act"), and
         take such further action as the Stockholders may reasonably request,
         from time to time to enable each Stockholder to sell the Parent Common
         Stock owned by it without registration under the 1933 Act pursuant to
         the exemption provided by Rule 144.

                           (iv) Agree to customary indemnification and other
         provisions in connection with preparation and filing of the
         Registration Statement.

                           (v) Pay all legal and accounting fees, all printing
         fees and all other fees, costs and expenses in connection with the
         preparation and filing of the Registration Statement.

                                    ARTICLE V

                       CONDUCT PRIOR TO THE EFFECTIVE TIME

         During the period from the date of this Agreement and continuing until
the earlier of the termination of this Agreement and the Effective Time, the
Company agrees (except to the extent that Parent shall otherwise consent in
writing) to carry on its business in the usual, regular and ordinary course of
business in substantially the same manner as heretofore conducted, to pay its


                                       38
<PAGE>   43
debts and Taxes when due, to pay or perform other obligations when due, and, to
the extent consistent with such business, to use all reasonable efforts
consistent with past practice and policies to preserve intact its present
business organization, keep available the services of its present officers and
key employees and preserve their relationships with customers, suppliers,
distributors, licensors, licensees, and others having business dealings with it,
all with the goal of preserving unimpaired its goodwill and ongoing businesses
at the Effective Time. The Company shall promptly notify Parent of any
materially negative event involving or adversely affecting the Company or its
business. By way of amplification and not limitation, except as expressly
contemplated by this Agreement, the Company shall not without the prior written

               SURVIVAL OF REPRESENTATIONS AND WARRANTIES; ESCROW

         8.1      SURVIVAL OF REPRESENTATIONS AND WARRANTIES.

         All of the representations and warranties of the Company and the
Stockholders in this Agreement or in any instrument delivered pursuant to this
Agreement shall survive the Merger and continue until 5:00 p.m., Delaware time,
on the date which is the twelve-month anniversary of the Closing Date (the
"Expiration Date"). All of the covenants and agreements of the parties hereto
shall survive the Merger without limitation.

         8.2      ESCROW ARRANGEMENTS; SECURITYHOLDER AGENT.

                  (a) Escrow Funds. At the Effective Time, the Company's
         stockholders will be deemed to have received from Parent and deposited
         with the Escrow Agent the Escrow Shares (plus any additional shares as
         may be issued upon any stock split, stock dividend or recapitalization
         effected by Parent after the Effective Time) without any act on the
         part of any stockholder. As soon as practicable after the Effective
         Time, the Escrow Shares, without any act on the part of any Company
         stockholder, will be deposited with First Union National Bank as Escrow
         Agent (the "Escrow Agent"), pursuant to an Escrow Agreement, such
         deposits to constitute three escrow funds (the "Escrow Funds") to serve
         as the exclusive (other than with respect to claims of fraud or
         intentional misrepresentation) source from which any Losses (defined in
         Section 8.3) of the Parent, its officers, directors, agents and
         Affiliates (including the Surviving Corporation) may be indemnified
         pursuant to the provisions of Section 8.3. The Company Stockholders
         shall not be required to contribute additional shares of Parent Common
         Stock or any other asset or cash (other than cash received as a result
         of a sale of Escrow Shares by the Escrow Agent at the request of the
         Securityholder Agent) to the Escrow Funds after the Effective Time. The
         Escrow Funds shall be governed by the terms set forth herein and in the
         Escrow Agreement. The number of Escrow Shares deposited on behalf of
         each stockholder of the Company shall be in proportion to the aggregate
         Parent Common Stock to which such holder would otherwise be entitled
         under Section 1.6(a) and shall be in the respective share amounts and
         percentages listed opposite each Company stockholder's name listed in
         Schedules to be attached to the Escrow Agreement in form and substance
         reasonably acceptable to Parent to be executed by the Company and
         delivered to Parent at Closing (individually, an "Escrow Schedule" and,
         collectively, the "Escrow Schedules"). No shares of Parent Common Stock
         deposited in the Escrow Funds shall be unvested or subject to any right
         of repurchase, risk of forfeiture or other condition in favor of the
         Company or the Surviving Corporation.

                  (b) Securityholder Agent of the Stockholders; Power of
         Attorney.

                           (i) By virtue of their approval of the Merger, the
                  stockholders of the Company (individually a "Company
                  Stockholder" and collectively the "Company Stockholders"),
                  including the Signing Stockholders, hereby appoint the
                  Securityholder Agent as agent and attorney-in-fact for each
                  stockholder of the

                  Company, for and on their behalf, to act as the Securityholder
                  Agent for the Company Stockholders under this Agreement and
                  under the Escrow Agreement and to give and receive notices and
                  communications, to agree to, negotiate, enter into settlements
                  and compromises of, and demand arbitration and comply with
                  orders of courts and awards of arbitrators with respect to
                  claims to authorize delivery to Parent of Escrow Shares from
                  the Escrow Funds in satisfaction of claims against the Escrow
                  Funds by Parent, to object to such deliveries, and to take all
                  actions necessary or appropriate in the judgment of
                  Securityholder Agent for the accomplishment of the foregoing
                  in accordance with the terms and provisions of this Agreement
                  and the Escrow Agreement. Such agency may be changed by the
                  Company Stockholders from time to time upon not less than
                  thirty (30) days prior written notice to Parent; provided that
                  the Securityholder Agent may not be removed unless holders of
                  a majority of the disinterested shares of Parent Common Stock
                  issued to the Company Stockholders in the Merger pursuant to
                  Section 1.6(a) agree to such removal and to the identity of

                  of a majority of the shares of Parent Common Stock issued to
                  the Company Stockholders in the Merger pursuant to Section
                  1.6(a). No bond shall be required of the Securityholder Agent,
                  and the Securityholder Agent shall not receive compensation
                  for his or her services. Notices or communications to or from
                  the Securityholder Agent hereunder shall constitute notice to
                  or from each of the Company Stockholders.

                           (ii) The Securityholder Agent shall not be liable for
                  any act done or omitted hereunder or under the Escrow
                  Agreement as Securityholder Agent while acting in good faith
                  and in the exercise of reasonable judgment. The Signing
                  Stockholders shall severally, on a pro rata basis in
                  proportion to each Signing Stockholder's percentage ownership
                  of the total amount of Company Common Stock received by all of
                  the Signing Stockholders in the Merger, indemnify the
                  Securityholder Agent and hold the Securityholder Agent
                  harmless against any loss, liability or expense incurred
                  without gross negligence or bad faith on the part of the
                  Securityholder Agent and arising out of or in connection with
                  the acceptance or administration of the Securityholder Agent's
                  duties hereunder, including (x) the reasonable fees and
                  expenses of any legal counsel retained by the Securityholder
                  Agent and (y) any loss, liability or expense arising out of
                  any claim brought against the Securityholder Agent by a
                  Company Stockholder who is not a Signing Stockholder (a
                  "Non-Signing Stockholder") relating to the Securityholder
                  Agent's acceptance or administration of his duties hereunder
                  without such Non-Signing Stockholder's consent.

                           (iii) Notwithstanding anything in this Agreement to
                  the contrary, the Securityholder Agent hereby agrees to notify
                  all Company Stockholders of any action taken by the
                  Securityholder Agent pursuant to this Agreement within seven
                  (7) days of the taking of any such action.

                  (c) Actions of the Securityholder Agent. A decision, act,
         consent or instruction of the Securityholder Agent relating to this
         Article VIII shall constitute a decision of all the Company
         Stockholders and shall be final, binding and conclusive upon

         written decision, consent or instruction of the Securityholder Agent as

         Stockholder. The Escrow Agent and Parent are hereby relieved from any
         liability to any Person for any acts done by them in accordance with
         such decision, consent or instruction of the Securityholder Agent.

                                    (J) [Reserved]

                                    (K) any liability not disclosed in the

                           which no services were performed by the Company;

                                    (L) [Reserved]

                                    (M) any liability with respect to the tax

                           Parent Schedules; or

                                    (N) any liability with respect to the
                           matters disclosed on Schedule 8.3(a)(i)(N) of the
                           Parent Schedules; provided, however, that such
                           indemnification obligation shall not apply to (i) the
                           employment agreements set forth in such schedule to
                           the extent that they impose no obligations on the
                           Company other than providing the relevant employees
                           two weeks notice of termination/severance and such
                           other obligations as may be imposed by Company policy
                           or applicable law; and (ii) contracts

                           set forth on such schedule to the extent that such
                           contracts were entered into by the Company in the
                           ordinary course of its business and any liabilities
                           associated thereto are also in the ordinary course of
                           business consistent with past practice.

provided, however, that the maximum amount of Losses for which the Company
Stockholders will be liable shall not exceed $4.7 million in the aggregate
(subject to the provisions of the Escrow Agreement), and subject to this
aggregate limitation, the maximum amount of Losses for which any holder of
Company Common Stock shall be liable shall equal the product of (x) such
holder's pro rata share of the issued and outstanding Company Common Stock as
set forth on Schedule 2.3(a) of the Company Schedules and (y) the Escrow Funds;
provided further, however, that the foregoing limitations shall not apply in the
case of fraud or intentional misrepresentation, in which case the maximum
liability of each Company Shareholder shall be limited to an amount equal to the
product of the Designated Stock Price times the number of Red Hat Shares
received by such Company Stockholder (including any shares deposited into the
Escrow Funds).

                           (ii) None of the Company Stockholders shall be liable
                  to Parent or its Affiliates (including the Surviving
                  Corporation) unless and until the aggregate amount of Losses
                  exceeds the Deductible, at which time, Parent and its
                  Affiliates (including the Surviving Corporation) may recover
                  all amounts of such Losses in excess of the Deductible,
                  provided, however, that any Losses attributable to a breach of
                  the representations in Sections 2.3, 2.10, 2.24 and 2.25(b),
                  and any Losses to be indemnified under Sections 8.3(a)(i)(C),
                  (F) and (M), shall be immediately reimbursable to Parent in
                  accordance with this Article VIII (without regard to the
                  Deductible and without counting toward the Deductible),
                  provided, further, that no Losses shall be indemnified under
                  Section 8.3(a)(i)(N) unless an individual Loss exceeds $5,000
                  or Losses to be indemnified exceed, in the aggregate, $25,000.
                  For purposes of this Section 8.3, the term "Deductible" shall
                  mean that dollar amount which equals $100,000.

                           (iii) Notwithstanding anything to the contrary
                  contained herein, to the extent that Third Party Expenses (as
                  defined in Section 10.2(a) below) incurred by the Company
                  exceed $250,000 in the aggregate, such excess shall be deemed
                  a Loss for purposes of this Article VIII and shall be
                  immediately reimbursable to Parent in accordance with this
                  Article VIII (without regard to the Deductible and without
                  counting toward the Deductible).

                           (iv) Losses shall be determined without regard to any
                  materiality or knowledge qualifiers that may be included in
                  any representation or warranty that is breached.

                           (v) No one (other than Parent) shall be permitted to
                  assert any indemnification claim under this Agreement unless
                  Parent shall have consented to the assertion of such claim.

                           (vi) Except as otherwise set forth in Section 10.10
                  of this Agreement, in the Nondisclosure Agreement, in any of
                  the Noncompetition, Nonsolicitation

                  and Nondisclosure Agreements or Affiliate Agreements executed
                  by Company Stockholders, the Company Stockholders shall not be
                  liable or responsible in any manner whatsoever for any Losses,
                  whether for indemnification or otherwise, except for indemnity
                  as expressly provided in this Section 8, and, except as set
                  forth above, this Section 8 provides the exclusive remedy and
                  cause of action of the Parent, its officers, directors and
                  agents and Affiliates (including the Surviving Corporation)
                  (but not including any claims of the Escrow Agent under the
                  Escrow Agreement) against the Company Stockholders with
                  respect to any claim arising out of this Agreement.

                           (vii) No Indemnified Party shall be entitled to
                  recover under this Section 8 (and any amounts paid otherwise
                  shall be promptly reimbursed to the Company Stockholders) to
                  the extent the subject matter of the Loss is reimbursed by
                  insurance proceeds received by such Indemnified Party.

                  (b)      Indemnification Procedures.

                           (i) Any claim for indemnification under Section
                  8.3(a)(i) must be asserted on or before 5:00 p.m. (Delaware
                  time) on the Expiration Date. Parent shall provide notice to
                  the Securityholder Agent within 30 days of Parent becoming
                  aware of any claims for Losses if such claims are reasonably
                  identifiable and determinable; provided, however, that no
                  delay or failure on the part of Parent in notifying the
                  Securityholder Agent shall relieve the Securityholder Agent or
                  the Company Stockholders from any obligation unless they are
                  materially prejudiced thereby (and then only to the extent of
                  such prejudice).

                           (ii) To make a claim for indemnification under this
                  Article VIII, Parent shall deliver to the Securityholder
                  Agent, acting as agent for the Company Stockholders
                  (collectively, the "Indemnifying Party") an officer's
                  certificate (the "Officer's Certificate"), which Officer's
                  Certificate shall:

                                    (A) state that Parent or its Affiliates
                           (including the Surviving Corporation) (individually
                           an "Indemnified Party") has paid or properly accrued
                           or reasonably anticipates that it will have to pay or
                           accrue Losses;

                                    (B) specify in reasonable detail the amount
                           of the claim for which the Officer's Certificate is
                           being delivered (the "Estimated Claim Amount"), the
                           date such amount was paid or properly accrued, or the
                           basis for such anticipated liability, and the nature
                           of the misrepresentation, breach of warranty or
                           covenant to which such amount is related;

                                    (C) state the sequential number of such
                           claim in relation to all Officer's Certificates
                           delivered hereunder;

                                    (D) set forth the date of such Officer's
                           Certificate;

                                    (E) state the aggregate Estimated Claim
                           Amounts of all claims as to which Officer's
                           Certificates have been delivered hereunder; and


                                       56
<PAGE>   61
                                    (F) contain a certification by an officer of
                           Parent that the claim is being made pursuant to this
                           Article VIII.

                           (iii) In case the Indemnifying Party shall object to
                  the indemnification of an Indemnified Party in respect of any
                  claim or claims specified in any Officer's Certificate, the
                  Indemnifying Party shall, within thirty (30) days after
                  receipt by the Indemnifying Party of such Officer's
                  Certificate, deliver to the Indemnified Party and the
                  Securityholder Agent a written notice to such effect and the
                  Indemnifying Party and the Indemnified Party shall, within the
                  thirty-day period beginning on the date of receipt by the
                  Indemnified Party of such written objection, attempt in good
                  faith to agree upon the rights of the respective parties with
                  respect to each of such claims to which the Indemnifying Party
                  shall have so objected. If the Indemnified Party and the
                  Indemnifying Party shall succeed in reaching agreement on
                  their respective rights with respect to any of such claims,
                  the Indemnified Party and the Indemnifying Party shall
                  promptly prepare and sign a memorandum setting forth such
                  agreement. Should the Indemnified Party and the Indemnifying
                  Party be unable to agree as to any particular item or items or
                  amount or amounts, then the Indemnified Party and the
                  Indemnifying Party shall submit such dispute to binding
                  arbitration in accordance with the provisions set forth in
                  Section 4(c) of the Escrow Agreement.

                           (iv) Promptly after the assertion by any third party
                  of any claim against any Indemnified Party that, in the
                  judgment of such Indemnified Party, may result in the
                  incurrence by such Indemnified Party of Losses for which such
                  Indemnified Party would be entitled to indemnification
                  pursuant to this Agreement, such Indemnified Party shall
                  deliver to the Indemnifying Party and the Securityholder Agent
                  a written notice describing in reasonable detail such claim
                  and such Indemnifying Party may, at its option, assume the
                  defense of the Indemnified Party against such claim (including
                  the employment of counsel, who shall be reasonably
                  satisfactory to such Indemnified Party, and the payment of
                  expenses); provided, however, that an Indemnifying Party may
                  not assume the defense of any claim the settlement of which,
                  or an adverse judgment with respect to which, is, in the good
                  faith judgment of Parent, likely to establish a precedential
                  custom or practice materially adverse to the continuing
                  business interests of Parent. The parties acknowledge that any
                  third party claim relating to Taxes, Intellectual Property or
                  the Company's products or services is likely to establish a
                  precedential custom or practice materially adverse to the
                  continuing business interests of Parent. Any Indemnified Party
                  shall have the right to employ separate counsel in any such
                  action or claim and to participate in the defense thereof, but
                  the fees and expenses of such counsel shall not be at the
                  expense of the Indemnifying Party (A) unless (i) the
                  Indemnifying Party shall have failed, within ten (10) days
                  after having been notified by the Indemnified Party of the
                  existence of such claim as provided in the preceding sentence,
                  to assume the defense of such claim or to notify the
                  Indemnified Party in writing that it will assume the defense
                  of such claim, (ii) the employment of such counsel has been
                  specifically authorized in writing by the Indemnifying Party,
                  or (iii) the named parties to any such action (including any
                  impleaded parties) include both such Indemnified Party and the
                  Indemnifying Party and such Indemnified Party shall have been

<PAGE>   62
                  advised by such counsel that there may be one or more legal
                  defenses available to the Indemnifying Party which are not
                  available to, or the assertion of which would be adverse to
                  the interests of, the Indemnified Party. No Indemnifying Party
                  shall be liable to indemnify any Indemnified Party for any
                  settlement of any such action or claim effected without the
                  consent of the Indemnifying Party, but if settled with the
                  written consent of the Indemnifying Party, or if there be a
                  final judgment (including all appeals or with all times for
                  appeal expired) for the plaintiff in any such action, the
                  Indemnifying Party shall indemnify and hold harmless each
                  Indemnified Party from and against any loss or liability by
                  reason of such settlement of judgment.

                           (v) Claims for Losses specified in any Officer's
                  Certificate to which an Indemnifying Party shall not object in
                  writing within thirty (30) days of receipt of such Officer's
                  Certificate, claims for Losses covered by a memorandum of
                  agreement of the nature described in paragraph (iii) and
                  claims for Losses the validity and amount of which shall have
                  been the subject of a final judicial determination as
                  described in paragraph (iv) are hereinafter referred to,
                  collectively, as "Agreed Claims". Within ten (10) business
                  days of the determination of the amount of any Agreed Claims,
                  the Indemnifying Party shall pay to the Indemnified Party an
                  amount equal to the Agreed Claim by providing notice of an
                  Agreed Claim to the Securityholder Agent and the Escrow Agent.

                        TERMINATION, AMENDMENT AND WAIVER

         9.1      TERMINATION.

         Except as provided in Section 9.2 below, this Agreement may be
terminated and the Merger abandoned at any time prior to the Closing Date
notwithstanding approval thereof by the stockholders of the Company:

                  (a) by mutual written consent duly authorized by the Board of
         Directors of the Company and Parent;

                  (b) by either Parent or the Company if (i) the Closing Date
         has not occurred by February 27, 2001 (the "Termination Date")
         (provided that the right to terminate this Agreement under this clause
         9.1(b)(i) shall not be available to any party whose failure to fulfill
         any obligation hereunder has been the cause of, or resulted in, the
         failure of the Effective Time to occur on or before such date and such
         action or failure constitutes a breach of this Agreement); (ii) there
         shall be a final nonappealable order, decree or ruling of a
         Governmental Entity having jurisdiction in effect preventing
         consummation of the Merger; or (iii) there shall be any statute, rule,
         regulation or order enacted, entered, enforced, promulgated, issued or
         deemed applicable to the Merger by any Governmental Entity which makes
         consummation of the Merger illegal;


                                       58
<PAGE>   63
                  (c) by Parent if there shall be any action taken, or any
         statute, rule, regulation or order enacted, promulgated or issued or
         deemed applicable to the Merger, by any Governmental Entity, which
         would: (i) prohibit Parent's or the Company's ownership or operation of
         any portion of the business of the Company or (ii) compel Parent or the
         Company to dispose of or hold separate, as a result of the Merger, any
         portion of the business or assets of the Company or Parent;

                  (d) by Parent if it is not in material breach of its
         obligations under this Agreement and there has been a breach of any
         representation, warranty, covenant or agreement contained in this
         Agreement on the part of the Company or the Company Stockholders and as
         a result of such breach the conditions set forth in Section 7.3(a) or
         7.3(b), as the case may be, would not then be satisfied; provided,
         however, that if such breach is curable by the Company or the Company
         Stockholders prior to the Termination Date through the exercise of its
         reasonable best efforts, then for so long as the Company or the Company
         Stockholders continue to exercise such reasonable best efforts Parent
         may not terminate this Agreement under this Section 9.1(d) unless such
         breach is not cured prior to the Termination Date (but no cure period
         shall be required for a breach which by its nature cannot be cured);

                  (e) by the Company if neither it nor the Company Stockholders
         are in material breach of their obligations under this Agreement and
         there has been a breach of any representation, warranty, covenant or
         agreement contained in this Agreement on the part of Parent or Merger
         Sub and as a result of such breach the conditions set forth in Section
         7.2(a) or 7.2(b), as the case may be, would not then be satisfied;
         provided, however, that if such breach is curable by Parent or Merger
         Sub prior to the Termination Date through the exercise of its
         reasonable best efforts, then for so long as Parent or Merger Sub
         continues to exercise such reasonable best efforts the Company may not
         terminate this Agreement under this Section 9.1(e) unless such breach
         is not cured prior to the Termination Date (but no cure period shall be
         required for a breach which by its nature cannot be cured).

         Where action is taken to terminate this Agreement pursuant to Section
9.1, it shall be sufficient for such action to be authorized by the Board of
Directors (as applicable) of the party taking such action.

         9.2      EFFECT OF TERMINATION.

         Except as set forth in Section 10.2, any termination of this Agreement
under Section 9.1 above will be effective immediately upon the delivery of
written notice of the terminating party to the other parties hereto. In the
event of the termination of this Agreement as provided in Section 9.1, this
Agreement shall be of no further force or effect, except (i) as set forth in
this Section 9.2 and Article X (general provisions, including expenses), each of
which shall survive the termination of this Agreement, and (ii) nothing herein
shall relieve any party from liability for any breach of this Agreement. No
termination of this Agreement shall affect the obligations of the parties
contained in the Nondisclosure Agreement, all of which obligations shall survive
termination of this Agreement.

         9.3      AMENDMENT.

         Except as is otherwise required by applicable law, prior to the
Closing, this Agreement may be amended by the parties hereto at any time by
execution of an instrument in writing signed by Parent and the Company. Except
as is otherwise required by applicable law, after the Closing, this Agreement
may be amended by the parties hereto at any time by execution of an instrument
in writing signed by Parent and by either the Securityholder Agent or former
Company stockholders who receive more than 66 2/3% of the Parent Common Stock
issued pursuant to Section 1.6(a).

         9.4      EXTENSION; WAIVER.

         At any time prior to the Effective Time, Parent and Merger Sub, on the
one hand, and the Company, on the other, may, to the extent legally allowed, (i)
extend the time for the performance of any of the obligations of the other party
hereto, (ii) waive any inaccuracies in the representations and warranties made
to such party contained herein or in any document delivered pursuant hereto and
(iii) waive compliance with any of the agreements or conditions for the benefit
of such party contained herein. Any agreement on the part of a party hereto to
any such extension or waiver shall be valid only if set forth in an instrument
in writing signed on behalf of such party.

<PAGE>   66
         for providing services with respect to the pooling), financial
         advisory, consulting and all other fees and expenses of third parties
         ("Third Party Expenses") incurred by a party in connection with the

         Company Stockholders shall indemnify the Company therefor pursuant to
         Section 8.3(a)(iii).

         10.3     INTERPRETATION.

         The words "include," "includes" and "including" when used herein shall
be deemed in each case to be followed by the words "without limitation." The
word "agreement" when used herein shall be deemed in each case to mean any
contract, commitment or other agreement, whether oral or written, that is
legally binding. The table of contents and headings contained in this Agreement
are for reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement. The term "Person" means any individual,
corporation, partnership, association, trust, limited liability company or
partnership, unincorporated organization, joint venture, other entity or group
(as defined in Section 13(d)(3) of the Exchange Act).

         10.4     COUNTERPARTS.

         This Agreement may be executed in one or more counterparts, all of
which shall be considered one and the same agreement and shall become effective
when one or more counterparts have been signed by each of the parties and
delivered to the other party, it being understood that all parties need not sign
the same counterpart.

         10.5     ENTIRE AGREEMENT; ASSIGNMENT.

         Except for the Nondisclosure Agreement, this Agreement, the schedules
and Exhibits hereto, and the documents and instruments and other agreements
among the parties hereto referenced herein: (a) constitute the entire agreement
among the parties with respect to the subject matter hereof and supersede all
prior agreements and understandings, both written and oral, among the parties
with respect to the subject matter hereof; (b) are not intended to confer upon
any other Person any rights or remedies hereunder; and (c) shall not be assigned
by operation of law or otherwise except as otherwise specifically provided,

         10.6     SEVERABILITY.

         In the event that any provision of this Agreement, or the application
thereof, becomes or is declared by a court of competent jurisdiction to be
illegal, void or unenforceable, the remainder of this Agreement will continue in
full force and effect and the application of such provision to other Persons or
circumstances will be interpreted so as reasonably to effect the intent of the
parties hereto. The parties further agree to replace such void or unenforceable
provision of this Agreement with a valid and enforceable provision that will
achieve, to the extent possible, the economic, business and other purposes of
such void or unenforceable provision.

         10.7     OTHER REMEDIES.

         Except as otherwise provided herein (including as set forth in Section
8.3(a)), any and all remedies herein expressly conferred upon a party will be
deemed cumulative with and not exclusive of any other remedy conferred hereby,
or by law or equity upon such party, and the exercise by a party of any one
remedy will not preclude the exercise of any other remedy.

         10.8     GOVERNING LAW.

         This Agreement shall be governed by and construed in accordance with
the laws of the State of North Carolina, regardless of the laws that might
otherwise govern under applicable principles of conflicts of laws thereof. Each
of the parties hereto agrees that process may be served upon them in any manner
authorized by the laws of the State of North Carolina for such persons and
waives and covenants not to assert or plead any objection which they might
otherwise have to such jurisdiction and such process.

         10.9     RULES OF CONSTRUCTION.

         The parties hereto agree that they have been represented by counsel
during the negotiation and execution of this Agreement and, therefore, waive the
application of any law, regulation, holding or rule of construction providing
that ambiguities in an agreement or other document will be construed against the
party drafting such agreement or document.

         10.10    SPECIFIC PERFORMANCE.

         Notwithstanding Section 8.2(b), the parties hereto agree that
irreparable damage would occur in the event that any of the provisions of this
Agreement were not performed in accordance with their specific terms or were
otherwise breached. It is accordingly agreed that the parties shall be entitled
to an injunction or injunctions to prevent breaches of this Agreement and to
enforce specifically the terms and provisions hereof in any court of the United
States or any state having jurisdiction, this being in addition to any other
remedy to which they are entitled at law or in equity.
