than 5 business days beyond the latest expiration date that would otherwise be
permitted under clause (i) or (ii) of this sentence but in no event may the
Offer extend beyond the Expiration Date.

     (b)  On the date of commencement of the Offer, Sprint shall file with the
SEC a Tender Offer Statement on Schedule 14D-1 with respect to the Offer, which
shall contain an offer to purchase and a related letter of transmittal and

amendments thereto, the "Offer Documents").  Sprint agrees that the Offer

order to make the statements therein, in light of the circumstances under which
they were made, not misleading, except that no representation is made by Sprint

Newco Sub specifically for inclusion in the Offer Documents.  Each of the
Parties agrees promptly to correct any information provided by it for use in the
Offer Documents if and to the extent that such information shall have become
false or misleading in any material respect, and Sprint further agrees to take
all steps necessary to amend or supplement the Offer Documents and to cause the
Offer Documents as so amended or supplemented to be filed with the SEC and to be
disseminated to the Company's stockholders, in each case as and to the extent
required by applicable Federal securities laws.  The Company and its counsel

amendments and supplements thereto prior to their filing with the SEC or

receipt of such comments.

consents to the Offer and the other transactions contemplated hereby and by the
Ancillary Agreements and the Company, Newco and Newco Sub represent and warrant
that the Boards of Directors of the Company, Newco and Newco Sub at meetings
duly called and held, duly and unanimously adopted resolutions, as appropriate,
approving this Agreement, the Ancillary Agreements, the Offer and the issuance
of the Convertible Preferred Stock to Sprint L.P. and the Convertible Notes to

Offer and the acquisition of the Convertible Preferred Stock, are fair to, and
in the best interests of, the Company's stockholders and recommending that those
stockholders who wish to receive cash for their shares of Common Stock, accept

     authority to own, lease and operate its properties and to carry on its
     business as now being conducted.  The Company is duly qualified or licensed
     to do business and is in good standing in each jurisdiction in which the
     nature of its business or the ownership or leasing of its properties makes
     such qualification or licensing necessary, other than in such jurisdictions
     where the failure to be so qualified or licensed (individually or in the
     aggregate) would not have a Material Adverse Effect on the Company.  The
     Company has made available to Sprint for its review complete and correct
     copies of its certificate of incorporation and bylaws, in each case as
     amended to the date of this Agreement.

          (b)  Subsidiaries and Joint Ventures. The Company does not have any
     Subsidiaries. The Company does not have the right to acquire an equity

     of Common Stock were available for the grant of Employee Stock Options
     pursuant to such plan (and upon approval by the Company's stockholders of a

     Common Stock that were not granted in tandem with a related Employee Stock
     Option. When issued and sold to Sprint, the Convertible Preferred Stock and

     and non-assessable and free and clear of all Liens. The Newco Common Stock
     issued upon conversion of the Convertible Preferred Stock and the

     date of this Agreement, there are not any securities, options, warrants,
     calls, rights to purchase, rights of first refusal, securities convertible
     into or exchangeable for voting securities, commitments, agreements,
     arrangements or undertakings of any kind to which the Company or any of its
     Subsidiaries is a party or by which any of them is bound obligating the
     Company to issue, deliver or sell or create, or cause to be issued,

     other than (i) liabilities provided for in the Company's unaudited balance
     sheet included in the Company's Quarterly Report on Form 10-Q for its third

     having individually or in the aggregate, a Material Adverse Effect on the
     Company, and (ii) the Company has not taken any action that would have been
     prohibited under Section 4.01 hereof as if the Agreement had been in effect
     on the date of such action.

     Documents or as set forth on Schedule 3.01(g), there is no suit, action or
     proceeding pending or, to the Knowledge of the Company, Threatened against

     Adverse Effect on the Company.

          (h)  Benefit Plans.

               (i)    Schedule 3.01(h) hereto contains a true and complete list
          of each Benefit Plan. With respect to each Benefit Plan, the Company

          connection with which the Company is now subject to, or could
          reasonably be expected to be subject to, any liability under ERISA,
          the Code, or any other applicable Law, except liability for benefit
          claims and funding obligations or contributions payable in the
          ordinary course, and to the Company's Knowledge each of the Benefit
          Plans has at all times in all material respects been in compliance
          with and administered in accordance with its terms, the applicable
          provisions of ERISA, the Code or any other applicable Law.

          intended to be qualified in form under Section 401(a) and tax exempt
          under Section 501(a) of the Code, respectively, has been determined by
          the IRS to so qualify under the Code and, to the Company's Knowledge,
          nothing has occurred since such determination to cause any of such
          Benefit Plans not to qualify under Section 401(a) or any of such
          related trusts not to be tax exempt under Section 501(a) of the Code
          other than the effective date of certain amendments of the Code and
          ERISA, the remedial amendment period for which has not expired.

          action, suit, grievance, arbitration or other claim with respect to
          the administration or investment of assets of the Benefit Plans (other
          than routine claims for benefits made in the ordinary course) pending,
          or to the Company's Knowledge, Threatened, and to the Company's
          Knowledge there is no present condition or set of circumstances which
          could reasonably be expected to give rise to any such action, suit,
          grievance, arbitration or other claim.

               (vi)   Neither the Company nor any corporation, trade or business
          which is affiliated with the Company, in the manner described in

     and accurate except where the failure to be complete or accurate would not
     have a Material Adverse Effect on the Company.  The Company has paid or has
     set up an adequate reserve for the payment of all Taxes shown as due on
     such Returns, except where the failure to do so would not have a Material

     which will be paid by the Company, is entitled to any broker's, finder's,
     financial advisor's or other similar fee or commission, in connection with
     the transactions contemplated by this Agreement and the Ancillary
     Agreements, based upon arrangements made by or on behalf of the Company
     (except as set forth on Schedule 3.01(k)).

          (l) Compliance with Laws. The Company has in effect all approvals,
     authorizations, certificates, filings, franchises, licenses, notices,
     permits, variances, exemptions, orders and rights ("Permits") necessary for
     it to own, lease or operate its properties and assets and to carry on its
     business as now conducted, and there has not occurred any default under any
     Permit, except for the absence of Permits and for defaults under Permits
     that, individually or in the aggregate, have not had a Material Adverse
     Effect on the Company. Except as disclosed in the Company Filed SEC
     Documents, the Company is in compliance with all applicable Law, except
     where failures to so comply, individually or in the aggregate, would not
     have a Material Adverse Effect on the Company. Except as set forth in
     Schedule 3.01(l) hereto or as described in Company Filed SEC Documents
     filed prior to the date hereof, as of the date of this Agreement, no
     investigation or review by any Governmental Entity with respect to the
     Company is pending or, to the Company's Knowledge, Threatened, other than,
     in each case, those the outcome of which would not have a Material Adverse
     Effect on the Company.

          (m) Environmental Matters. The Company is and at all times has been
     in full compliance with, and has not been and is not in violation of or
     liable under, any Environmental Law (which compliance includes the
     possession by the Company of all Permits required under applicable
     Environmental Law and compliance with the terms and conditions thereof),
     except for such failure to be in compliance which, individually or in the
     aggregate, would not have a Material Adverse Effect on the Company. There
     are no pending or, to the Company's Knowledge, Threatened claims, orders,
     notices, administrative or judicial actions, or Encumbrances, relating to
     environmental, health, and safety liabilities arising under or pursuant to
     any federal, state or local Environmental Laws, with respect to or
     affecting any of the properties and assets (whether real, personal, or
     mixed) in which the Company has an interest, except for any such claim,
     order, notice, administrative or judicial action, Encumbrance or other
     restriction that would not, individually or in the aggregate, have a
     Material Adverse Effect on the Company.

          (n) Intellectual Property. The Company owns sufficient right, title
     and interest in and to, or has valid licenses of sufficient scope and
     duration for, all patents, patent rights, copyrights, trademarks, service
     marks, trade names, software, trade secrets, confidential information and
     other intellectual property material to the operation of the business of
     the Company as currently conducted or

                                       23
<PAGE>
 
     proposed to be conducted (the "Intellectual Property Assets") and as
     presently proposed to be conducted. The Intellectual Property Assets are
     free and clear of all Liens which would materially impair the Company's
     ability to use the Intellectual Property Assets in the business of the
     Company as currently conducted or proposed to be conducted. The Company has
     granted to no third party any rights in and to the Intellectual Property
     Assets except for distribution rights, OEM rights, end user licenses and
     rights to reproduce certain of the Intellectual Property Assets in the
     Ordinary Course of Business in connection with the marketing and
     distribution of the Company's product and service offerings, and which
     individually and in the aggregate would not have a Material Adverse Effect.
     Except as set forth on Schedule 3.01(n), none of the Intellectual Property
     Assets owned or licensed by the Company infringes, or conflicts with, or to
     the Company's Knowledge, is alleged to infringe upon or conflict with the
     intellectual property rights of any third party, which infringement or
     alleged infringement could have a Material Adverse Effect. The Company has
     no Knowledge that any of its employees performing or managing key functions
     of the Company is obligated under any contract (including licenses,
     covenants or commitments of any nature) or other agreement, or subject to
     any judgment, decree or order of any court or administrative agency, that
     would interfere with the use of such employee's best efforts to promote the
     interests of the Company or that would conflict with the Company's business
     as proposed to be conducted. To the Company's Knowledge, neither the
     execution nor delivery of this Agreement or any Ancillary Agreement, nor
     the conduct of the Company's business by the employees of the Company, nor
     the conduct of the Company's business as proposed, will conflict with or
     result in a breach of the terms, conditions or provisions of, or constitute
     a default under, any contract, covenant or instrument under which any of
     such employees is now obligated, which conflict or breach would have a
     Material Adverse Effect. The Company does not presently utilize or intend
     to utilize any inventions of any of its employees (or people it currently
     intends to hire) made prior to their employment by the Company. To the
     Company's Knowledge, any software owned by the Company, and any software
     used independently by the Company and owned by third parties and licensed
     to the Company is, in all material respects, Year 2000 Compliant. "Year
     2000 Compliant" means (i) the software is capable of correctly processing,
     providing and receiving date data within and between the twentieth and
     twenty-first century (including accounting for all required leap year
     calculations); and (ii) all date fields in the software use four digit year
     fields.

          (o) Certain Payments. Neither the Company, nor any of its directors,
     officers, agents, or employees, or to the Company's Knowledge, any other
     Person associated with or acting for or on behalf of the Company, has
     directly or indirectly (a) made any contribution, gift, bribe, rebate,
     payoff, influence payment, kickback, or other payment to any Person,
     private or public, regardless of form, whether in money, property, or
     services (i) to obtain favorable treatment in securing business, (ii) to
     pay for favorable treatment for business secured, (iii) to obtain special
     concessions or for special concessions already obtained, for or in respect
     of the Company or any Affiliate of the Company, (b) established or
     maintained any fund or asset that has not been appropriately recorded in
     the books and records of the Company, which in the case of either clause
     (a) or (b) would be in violation of Law or would have a Material Adverse
     Effect.

     standing in each jurisdiction in which the nature of the business conducted
     or the ownership or leasing of its properties makes such qualification or
     licensing necessary, other than in such jurisdictions where the failure to
     be so qualified or licensed (individually or in the aggregate) would not
     have a Material Adverse Effect on Newco immediately following the Merger.
     Each of Newco and Newco Sub has made available to Sprint for its review
     complete and correct copies of its certificate of incorporation and bylaws,
     in each case as amended to the date of this Agreement.

     and the Company, constitute valid and binding obligations of each of them
     enforceable against Newco and Newco Sub, respectively, in accordance with
     their respective terms, except to the extent that the enforcement hereof
     and thereof may be limited by (i) bankruptcy, insolvency, reorganization,
     moratorium or other similar laws now or hereafter in effect relating to
     creditors' rights generally, and (ii) general principles of equity

     or result in any violation of, or default (with or without notice or lapse
     of time, or both) under, or give rise to a right of termination,
     cancellation or acceleration of any obligation or to loss by Newco or Newco

     Liens that individually or in the aggregate would not (x) have a Material
     Adverse Effect on Newco or Newco Sub, (y) materially impair the ability of
     Newco and Newco Sub to perform its obligations under this Agreement or any

     the Knowledge of Newco or Newco Sub, Threatened against Newco or Newco Sub.

          (d)  Voting Requirements. The only vote of the holders of any class or
     series of the capital stock of Newco and Newco Sub that is necessary to
     approve this Agreement, the Ancillary Agreements or the transactions

     outstanding shares of common stock entitled to vote with respect to the
     Merger, as required by Section 251 of the DGCL.

          (e)  Brokers. No broker, investment banker, financial advisor or other
     person, other than Deutsche Morgan Grenfell Inc., the fees and expenses of

     Company, except for such Permits, the absence of which would not have,
     individually or in the aggregate, a Material Adverse Effect on Newco and
     Newco Sub, taken as a whole.

     SECTION 3.03   Representations and Warranties of Sprint and Sprint L.P..
Sprint and Sprint L.P., jointly and severally, represent and warrant to the
Company, Newco and Newco Sub as follows:

          (a)  Organization, Standing and Power. Sprint is a corporation duly

     jurisdiction in which it is incorporated. Sprint L.P. is a limited
     partnership duly organized, validly existing and in good standing under the

     Sprint L.P. has all requisite power and authority to own, lease and operate

     now being conducted. Each of Sprint and Sprint L.P. and each of their
     respective Significant Subsidiaries is duly qualified or licensed to do
     business and is in good standing in each jurisdiction in which the nature
     of its business or the ownership or leasing of its properties makes such
     qualification or licensing necessary, other than in such jurisdictions
     where the failure to be so qualified or licensed (individually or in the
     aggregate) could not reasonably be expected to have a Material Adverse
     Effect on Sprint or Sprint L.P. and their respective Subsidiaries, taken as
     a whole. Sprint has made available to the Company, Newco and Newco Sub for
     their review complete and correct copies of its certificate of
     incorporation and bylaws. Sprint L.P. has made available to the Company,
     Newco and Newco Sub for their review a complete and correct copy of its

     for 1996 lists each Significant Subsidiary of Sprint. All the outstanding
     shares of capital stock of each Significant Subsidiary that is a
     corporation have been validly issued and are fully paid and nonassessable
     and are not subject to any options or other rights to acquire any such
     shares.

          (c)  Authority; Noncontravention. Sprint has the requisite corporate
     power and authority, and Sprint L.P. has the requisite power and authority,

     consummation by it of the transactions contemplated by this Agreement and
     the Ancillary Agreements have been duly authorized by, in the case of
     Sprint, all necessary corporate action, and in the case of Sprint L.P., all
     necessary action of the limited partnership and its general partner. This
     Agreement and the Ancillary Agreements to which Sprint or Sprint L.P. is
     party have been duly executed and delivered by Sprint and Sprint L.P. and,
     assuming this Agreement and the Ancillary Agreements constitute the valid
     and binding agreements of the Company, Newco and Newco Sub, constitute
     valid and binding obligations enforceable against Sprint and Sprint L.P. in
     accordance with their respective terms, except to the extent

                                       27
<PAGE>
 
     that the enforcement of this Agreement or the Ancillary Agreements may be
     limited by (i) bankruptcy, insolvency, reorganization, moratorium or other
     similar laws now or hereafter in effect relating to creditors' rights
     generally, and (ii) general principles of equity regardless of whether

     set forth on Schedule 3.03(c), the execution and delivery of this Agreement
     and the Ancillary Agreements by Sprint and Sprint L.P. did not, and the
     consummation of the transactions contemplated by this Agreement and the

     rise to a right of termination, cancellation or acceleration of any
     obligation or to loss by Sprint, Sprint L.P. or any of Sprint's Significant
     Subsidiaries, of a material benefit under, or result in the creation of any
     Lien upon any of the properties or assets of Sprint or Sprint L.P. under,
     (i) the certificate of incorporation or bylaws of Sprint or the comparable
     charter or organizational documents of Sprint L.P. or any of Sprint's
     Significant Subsidiaries, (ii) any loan or credit agreement, note, bond,
     mortgage, indenture, lease or other agreement, instrument, permit or

     Subsidiaries or their respective properties or assets or (iii) subject to
     the governmental filings and other matters referred to in the following
     sentence, any judgment, order, decree, statute, law, ordinance, rule or
     regulation applicable to Sprint, Sprint L.P. or any of Sprint's Significant
     Subsidiaries or their respective properties or assets, other than, in the
     case of clauses (ii) and (iii), any such conflicts, violations, defaults,
     rights or Liens that individually or in the aggregate would not (x) have a
     Material Adverse Effect on Sprint, Sprint L.P. and Sprint's Subsidiaries,
     taken as a whole, (y) materially impair the ability of Sprint or Sprint
     L.P. to perform their respective obligations under this Agreement or any
     Ancillary Agreement to which it is a party or (z) prevent the consummation
     of any of the transactions contemplated by this Agreement or any of the
     Ancillary Agreements. No consent, approval, order or authorization of, or
     registration, declaration or filing with, any Governmental Entity is
     required by or with respect to Sprint or Sprint L.P. or any of Sprint's
     Significant Subsidiaries in connection with the execution and delivery of
     this Agreement and the Ancillary Agreements or the consummation by Sprint
     or Sprint L.P. of the transactions contemplated by this Agreement and the
     Ancillary Agreements, except for (i) the filing of a premerger notification
     and report form by Sprint or Sprint L.P. under the HSR Act and the
     expiration of the applicable waiting period or early termination thereof
     and, (ii) the filing with the SEC of (x) a tender offer statement on

     person, other than SBC Warburg Dillon Read, Inc. the fees and expenses of
     which will be paid by Sprint, is entitled to any broker's, finder's,
     financial advisor's or other similar fee or

                                       28
<PAGE>
 
     commission in connection with the transactions contemplated by this
     Agreement and the Ancillary Agreements based upon arrangements made by or
     on behalf of Sprint or Sprint L.P.

          (e)  Ownership of Common Stock. As of the date of this Agreement,
     neither Sprint nor Sprint L.P. beneficially owns any shares of Common
     Stock.

          (f)  Investment Intent. Sprint is purchasing the Convertible Notes for
     advances under the Credit Agreement, and Sprint L.P. is purchasing the
     Convertible Preferred Stock in exchange for the Preferred Stock
     Consideration, in each case for their own account for investment and not
     with a present view to, or for sale in connection with, any distribution
     thereof in violation of the Securities Act. The certificates evidencing the
     Convertible Preferred Stock, the Convertible Notes and any shares of Common
     Stock issued upon conversion of the Convertible Preferred Stock or the
     Convertible Notes shall bear substantially the following legend (modified
     accordingly in the case of the Convertible Notes) until such time as there
     is a sale or transfer in accordance with this Agreement and the Ancillary
     Agreements or the termination thereof:

          "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN
          ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN
          CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF. THE
          DISPOSITION AND VOTING OF SUCH SHARES IS SUBJECT TO THE
          CONDITIONS SPECIFIED IN THE INVESTMENT AGREEMENT DATED AS OF
          FEBRUARY 10, 1998, AMONG THE COMPANY, SPRINT, SPRINT L.P.,
          NEWCO, AND NEWCO SUB AND THE GOVERNANCE AGREEMENT DATED AS
          OF FEBRUARY 10, 1998, AMONG THE COMPANY, SPRINT, SPRINT
          L.P., AND NEWCO, AND NEWCO RESERVES THE RIGHT TO REFUSE THE
          TRANSFER OF SUCH SHARES UNTIL SUCH CONDITIONS HAVE BEEN
          FULFILLED WITH RESPECT TO SUCH TRANSFER. A COPY OF SUCH
          CONDITIONS WILL BE FURNISHED BY NEWCO TO THE HOLDER HEREOF
          UPON WRITTEN REQUEST AND WITHOUT CHARGE. THESE SECURITIES
          HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
          AS AMENDED, AND MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED
          OR HYPOTHECATED EXCEPT IN ACCORDANCE THEREWITH."

          (g)  Acquisition for Investment and Rule 144. Sprint and Sprint L.P.
     understand that the shares of Convertible Preferred Stock issued to them
     pursuant to the Agreement ("Sprint Shares") and Sprint understands that the
     Convertible Notes issued to Sprint pursuant to the Credit Agreement will
     not be registered under the Securities Act by reason of a specific
     exemption from the registration provision of the Securities Act which
     depends upon, among other things, the bona fide nature of their investment
     intent as expressed herein. Except as otherwise provided in Section
     3.03(i), Sprint and Sprint L.P. acknowledge that the Sprint Shares and the
     Convertible Notes must be held indefinitely unless they are subsequently

                                       29
<PAGE>
 
     registered under the Securities Act or an exemption from such registration
     is available. Sprint and Sprint L.P. have been advised or are aware of the
     provisions of Rule 144 promulgated under the Securities Act which permit
     limited resale of shares purchased in a private placement subject to the
     satisfaction of certain conditions. Sprint and Sprint L.P. are aware that
     the certificates representing the Sprint Shares, and that the Convertible
     Notes, will bear such legends relating to restrictions on resale under the
     Securities Act as provided in Section 3.01(f) and Newco under certain
     conditions may issue instructions to its stock transfer agent to stop the
     transfer of the Sprint Shares and the Convertible Notes unless made in
     accordance with this Agreement or any Ancillary Agreement.

          (h)  Legal Investment. The purchase of the Convertible Preferred Stock
     by Sprint L.P. and the purchase of Convertible Notes by Sprint hereunder is
     legally permitted by all applicable Law and all consents, approvals,
     authorizations of or designations, declarations or filings in connection
     with the valid execution and delivery of this Agreement by Sprint and
     Sprint L.P. or the purchase of the Convertible Preferred Stock by Sprint
     L.P. and the Convertible Notes by Sprint have been obtained, or will be
     obtained prior to the Closing Date.

          (i)  Purchase Entirely for Own Account. Sprint is purchasing the
     Convertible Notes for advances under the Credit Agreement, and Sprint L.P.
     is purchasing the Convertible Preferred Stock in exchange for the Preferred
     Stock Consideration, in each case for their own account and not as a
     nominee or agent, and not with a view to the resale or distribution of any
     part thereof, except for transfers permitted by this Agreement. Neither
     Sprint L.P. nor Sprint has any present intention of selling, granting any
     participation in, or otherwise distributing the Convertible Preferred Stock
     or the Convertible Notes. Neither Sprint nor Sprint L.P. has any contract,
     undertaking, agreement or arrangement with any Person to sell, transfer or
     grant participations to such Person or to any third person with respect to
     the Convertible Preferred Stock or the Convertible Notes. Notwithstanding
     any other provision of this Agreement, Sprint and Sprint L.P. shall be
     permitted to transfer the Convertible Preferred Stock, the Convertible
     Notes and the Newco Common Stock issued upon conversion thereof to any
