the satisfaction (or waiver) of all conditions to the obligations of the parties
hereunder, or at such other place, time or date as the Company and the

Purchasers, and the Purchasers shall, severally, and not jointly, purchase or

of the aggregate purchase price shall be made by the Escrow Agent to the Company

immediately available funds upon written instructions of the Company in

     transactions.

          (ii) Each party shall furnish to the other party all information

                                  ARTICLE III

          SECTION 3.1.  Organization and Qualification.  The Company and each of
     its subsidiaries is a corporation duly organized and existing in good
     standing under the laws of the jurisdiction in which it is incorporated,
     and has the requisite corporate power to own its properties and to carry on
     its business as now being conducted. The Company and each of its
     subsidiaries is duly qualified as a foreign corporation to do business and
     is in good standing in every jurisdiction in which the nature of the
     business conducted by it makes such qualification necessary and where the
     failure so to qualify would have a Material Adverse Effect with respect to
     the Company.

          SECTION 3.2.  Authorization; Enforcement.  (i) The Company has the
     requisite corporate power and authority to enter into and perform its
     obligations under this Agreement and the Related Agreements, to issue and
     sell the Purchased Securities in accordance with the terms hereof, to issue
     the shares of Common Stock issuable upon conversion of the Preferred Shares
     in accordance with the terms thereof, and to issue the shares of Common
     Stock upon exercise of the Warrants in accordance with the terms thereof;
     (ii) the execution, delivery and performance of this Agreement and the
     Related Agreements by the Company and the consummation by it of the
     transactions contemplated hereby and thereby (including, without
     limitation, the issuance of the Preferred Shares and the Warrants and the
     issuance and reservation for issuance of the shares of Common Stock
     issuable upon conversion of the Preferred Shares and upon exercise of the
     Warrants) have been duly authorized by the Company's Board of Directors and
     no further consent or authorization of the Company, its Board of Directors,
     any or committee of the Board of Directors is required, and (iii) this
     Agreement constitutes, and, upon execution and delivery by the Company of
     the Registration Rights Agreement, the Preferred Shares and the Warrants,
     such agreements will constitute, valid and binding obligations of the

          SECTION 3.3.  Intentionally Omitted.

     and exercise of the Warrants is set forth on SCHEDULE 3.4. All of such

     validly issued, fully paid and non-assessable. No shares of capital stock
     of the Company (including the shares of Common Stock issuable upon
     conversion of the Preferred Shares and upon exercise of the Warrants) are
     subject to preemptive rights or any other similar rights of the
     stockholders of the Company or any Liens. Except for the Purchased
     Securities (including the shares of Common Stock issuable upon conversion
     of the Preferred Shares and upon exercise of the Warrants) and as set forth
     on SCHEDULE 3.4, as of the date of this Agreement, (i) there are no
     outstanding options, warrants, scrip, rights to subscribe to, calls or
     commitments of any character whatsoever relating to, or securities or
     rights convertible into or exercisable or exchangeable for, any shares of
     Capital Securities of the Company or any of its subsidiaries, or
     arrangements by which the Company or any of its subsidiaries is or may
     become bound to issue additional shares of Capital Securities of the
     Company or any of its subsidiaries, nor are any such issuances or
     arrangements contemplated, and (ii) there are no agreements

                                       5
<PAGE>   13

     or arrangements under which the Company or any of its subsidiaries is
     obligated to register the sale of any of its or their Capital Securities
     under the Securities Act (except the Second Amended and Restated
     Shareholders' and Registration Rights Agreement dated as of April 16, 1997
     and amended as of September 20, 1999, and the Second Amended and Restated
     Agreement Among Series E, Series F and Series G Preferred Stockholders and
     Senior Registration Rights Agreement dated as of September 7, 1999 and
     amended as of September 20, 1999, between the Company and certain of its
     shareholders). SCHEDULE 3.4 sets forth all of the Company issued securities
     or instruments containing anti-dilution or similar provisions that will be
     triggered by, and all of the resulting adjustments that will be made to
     such securities and instruments as a result of, the issuance of the
     Purchased Securities (including the shares of Common Stock issuable upon
     conversion of the Preferred Shares and upon exercise of the Warrants) in
     accordance with the terms of this Agreement or any of the Related
     Agreements. The Company has furnished to the Purchasers true and correct
     copies of the Company's Certificate of Incorporation as in effect on the
     date hereof ("CERTIFICATE OF INCORPORATION"), the Company's By-laws as in
     effect on the date hereof (the "BY-LAWS"), and all other instruments and
     agreements governing securities convertible into or exercisable or
     exchangeable for capital stock of the Company.

          SECTION 3.5.  Issuance of Shares.  The shares of Common Stock issuable
     upon conversion of the Preferred Shares and upon exercise of the Warrants
     are duly authorized and reserved for issuance, and, upon conversion of the
     Preferred Shares and exercise of the Warrants in accordance with the terms
     thereof, will be validly issued, fully paid and non-assessable, and free
     from all taxes, liens, claims and encumbrances and will not be subject to
     preemptive rights, rights of first refusal or other similar rights of
     stockholders of the Company and will not impose personal liability upon the
     holder thereof.

          SECTION 3.6.  No Conflicts.  The execution, delivery and performance
     of this Agreement and the Related Agreements by the Company, and the
     consummation by the Company of the transactions contemplated hereby and
     thereby (including, without limitation, the issuance and reservation for
     issuance, as applicable, of the Preferred Shares, the Warrants, the shares
     of Common Stock issuable upon conversion of the Preferred Shares and the
     shares of Common Stock issuable upon exercise of the Warrants will not (i)
     result in a violation of the Certificate of Incorporation or By-laws or
     (ii) conflict with, or constitute a default (or an event that with notice
     or lapse of time or both would become a default) under, or give to others
     any rights of termination, amendment (including, without limitation, the
     triggering of any anti-dilution provisions), acceleration or cancellation
     of, any agreement, indenture or instrument to which the Company or any of
     its subsidiaries is a party, or result in a violation of any law, rule,
     regulation, order, judgment or decree (including United States federal and
     state securities laws and regulations and rules or regulations of any
     self-regulatory organizations to which either the Company or its securities
     are subject) applicable to the Company or any of its subsidiaries or by
     which any property or asset of the Company or any of its subsidiaries is
     bound or affected (except, with respect to clause (ii), for such conflicts,
     defaults, terminations, amendments, accelerations, cancellations and
     violations that would not, individually or in the aggregate, have a
     Material Adverse Effect with respect to the Company). Neither the Company
     nor any of its subsidiaries is in violation of its Certificate of
     Incorporation, By-laws or other organizational documents and neither the
     Company nor any of its subsidiaries is in default (and no event has
     occurred which, with notice or lapse of time or both, would put the Company
     or any of its subsidiaries in default) under, nor has there occurred any
     event giving others (with notice or lapse of time or both) any rights of
     termination, amendment, acceleration or cancellation of, any agreement,
     indenture or instrument to which the Company or any of its subsidiaries is
     a party, except for actual or possible violations, defaults or rights that
     would not, individually or in the aggregate, have a Material Adverse Effect
     with respect to the Company. The businesses of the Company and its
     subsidiaries are not being conducted, and shall not be conducted so long as
     the Purchasers own any of the Purchased Securities (including the shares of
     Common Stock issuable upon conversion of the Preferred Shares and upon
     exercise of the Warrants), in violation of any law, ordinance or regulation
     of any governmental entity, except for possible violations the sanctions
     for which either singly or in the aggregate would not have a Material
     Adverse Effect with respect to the Company. Except as specifically
     contemplated by this Agreement and the Registration Rights Agreement, the
     Company is not required to obtain any consent, approval, authorization or
     order of, or make any filing or registration with, any court

                                       6
<PAGE>   14

     or governmental agency or any regulatory or self regulatory agency or other
     third party in order for it to execute, deliver or perform any of its
     obligations under this Agreement or any of the Related Agreements, in each
     case in accordance with the terms hereof or thereof. The Company is not in
     violation of the listing requirements of the NASDAQ National Market
     ("NASDAQ") and does not reasonably anticipate that the Common Stock will be
     delisted by NASDAQ for the foreseeable future.

          SECTION 3.7.  SEC Documents, Financial Statements.  Since December 6,
     1999, the Company has timely filed (within applicable extension periods)
     all reports, schedules, forms, statements and other documents required to
     be filed by it with the SEC pursuant to the reporting requirements of
     Sections 13, 14 and 15(d) of the Securities Exchange Act (all of the
     foregoing filed prior to the date hereof and all exhibits included therein
     and financial statements and schedules thereto and documents incorporated
     by reference therein, being hereinafter referred to herein as the "SEC
     DOCUMENTS"). As of their respective dates, the SEC Documents complied in
     all material respects with the requirements of the Securities Exchange Act
     or the Securities Act, as the case may be, and the rules and regulations of
     the Securities and Exchange Commission ("SEC") promulgated thereunder
     applicable to the SEC Documents, and none of the SEC Documents, at the time
     they were filed with the SEC, contained any untrue statement of a material
     fact or omitted to state a material fact required to be stated therein or
     necessary in order to make the statements therein, in light of the
     circumstances under which they were made, not misleading. None of the
     statements made in any such SEC Documents is, or has been, required to be
     amended or updated under applicable law (except for such statements as have
     been amended or updated in subsequent filings made prior to the date
     hereof). As of their respective dates, the financial statements of the
     Company included in the SEC Documents complied as to form in all material
     respects with applicable accounting requirements and the published rules
     and regulations of the SEC applicable with respect thereto. Such financial
     statements have been prepared in accordance with U.S. generally accepted
     accounting principles ("GAAP"), consistently applied, during the periods
     involved (except (i) as may be otherwise indicated in such financial
     statements or the notes thereto, or (ii) in the case of unaudited interim
     statements, to the extent they may not include footnotes or may be
     condensed or summary statements) and fairly present in all material
     respects the consolidated financial position of the Company and its
     consolidated subsidiaries as of the dates thereof and the consolidated
     results of their operations and cash flows for the periods then ended
     (subject, in the case of unaudited statements, to immaterial year-end audit
     adjustments). Except as set forth in the financial statements of the
     Company included in the SEC Documents filed prior to the date hereof, the
     Company has no liabilities, contingent or otherwise, other than (i)
     liabilities incurred in the ordinary course of business subsequent to the
     date of such financial statements and (ii) obligations under contracts,
     leases and commitments incurred in the ordinary course of business and not
     required under GAAP to be reflected in such financial statements, which
     liabilities and obligations referred to in clauses (i) and (ii),
     individually or in the aggregate, are not material to the financial
     condition or operating results of the Company.

          SECTION 3.8.  Absence of Certain Changes.  Since November 14, 2000,
     there has been no material adverse change and no material adverse
     development in the business, properties, operations, prospects, financial
     condition or results of operations of the Company and its subsidiaries,
     taken as a whole, except as disclosed in the draft filing on Form 10-K
     ("DRAFT 10-K") for the year ended December 31, 2000, in the SEC Documents
     filed on or before the date hereof or in this Agreement and the Schedules
     hereto.

          SECTION 3.9.  Absence of Litigation.  Except as disclosed in the SEC
     Documents filed on or before the date hereof, the Draft 10-K, or in this
     Agreement and in SCHEDULE 3.9 hereto, there is no action, suit, proceeding,
     inquiry or investigation before or by any court, public board, government
     agency, self-regulatory organization or body, including, without
     limitation, the Securities and Exchange Commission or NASDAQ, pending or,
     to the knowledge of the Company or any of its subsidiaries, threatened
     against or affecting the Company, any of its subsidiaries, or any of their
     respective directors or officers in their capacities as such. To the best
     knowledge of the Company, there are no facts which, if known by a potential
     claimant or governmental authority, could give rise to a claim or
     proceeding which, if asserted or

                                       7
<PAGE>   15

     conducted with results unfavorable to the Company or any of its
     subsidiaries, could reasonably be expected to have a Material Adverse
     Effect with respect to the Company.

          SECTION 3.10.  Intellectual Property.  To the best knowledge of the
     Company, each of the Company and its subsidiaries owns or is licensed to
     use all patents, patent applications, trademarks, trademark applications,
     trade names, service marks, copyrights, copyright applications, licenses,
     permits, inventions, discoveries, processes, scientific, technical,
     engineering and marketing data, object and source codes, know-how
     (including trade secrets and other unpatented and/or unpatentable
     proprietary or confidential information, systems or procedures) and other
     similar rights and proprietary knowledge necessary for the conduct of its
     business as now being conducted (collectively, "INTANGIBLES"). To the best
     knowledge of the Company, neither the Company nor any subsidiary of the
     Company infringes or is in conflict with any right of any other person with
     respect to any Intangibles which, if the subject of an unfavorable
     decision, ruling or finding, would have a Material Adverse Effect with
     respect to the Company. Neither the Company nor any of its subsidiaries has
     received written notice of any pending conflict with or infringement upon
     such third party Intangibles. Neither the Company nor any of its
     subsidiaries has entered into any consent agreement, indemnification
     agreement, forbearance to sue or settlement agreement with respect to the
     validity of the Company's or its subsidiaries' ownership or right to use
     its Intangibles and there is no reasonable basis for any such claim to be
     successful. To the best knowledge of the Company, the Intangibles are valid
     and enforceable and no registration relating thereto has lapsed, expired or
     been abandoned or canceled or is the subject of cancellation or other
     adversarial proceedings, and all applications therefor are pending and in
     good standing, except for any registration or application, the loss of
     which would not individually or in the aggregate have a Material Adverse
     Effect on the Company. The Company and its subsidiaries have complied, in
     all material respects, with their respective contractual obligations
     relating to the protection of the Intangibles used pursuant to licenses. To
     the best knowledge of the Company, no person is infringing on or violating
     the Intangibles owned or used by the Company or its subsidiaries.

          SECTION 3.11.  Foreign Corrupt Practices.  Neither the Company, nor
     any of its subsidiaries, nor any director, officer, agent, employee or
     other person acting on behalf of the Company or any subsidiary has, in the
     course of his actions for, or on behalf of, the Company, used any corporate
     funds for any unlawful contribution, gift, entertainment or other unlawful
     expenses relating to political activity; made any direct or indirect
     unlawful payment to any foreign or domestic government official or employee
     from corporate funds; violated or is in violation of any provision of the
     U.S. Foreign Corrupt Practices Act of 1977; or made any bribe, rebate,
     payoff, influence payment, kickback or other unlawful payment to any
     foreign or domestic government official or employee.

          SECTION 3.12.  Disclosure.  All information relating to or concerning
     the Company set forth in this Agreement or provided to the Purchaser
     pursuant to SECTION 4.5 hereof or otherwise in connection with the
     transactions contemplated hereby is true and correct in all material
     respects and the Company has not omitted to state any material fact
     necessary in order to make the statements made herein or therein, in light
     of the circumstances under which they were made, not misleading. Except for
     confidential information disclosed to the Purchasers, no event or
     circumstance has occurred or exists with respect to the Company or its
     subsidiaries or their respective businesses, properties, prospects,
     operations or financial conditions, which has not been publicly disclosed
     but, under applicable law, rule or regulation, would be required to be
     disclosed by the Company in a registration statement filed on the date
     hereof by the Company under the Securities Act with respect to a primary
     issuance of the Company's securities.

          SECTION 3.13.  Acknowledgment Regarding Purchasers' Purchase of the
     Purchased Securities. The Company acknowledges and agrees that no Purchaser
     is acting as a financial advisor or fiduciary of the Company (or in any
     similar capacity) with respect to this Agreement or the transactions
     contemplated hereby, the relationship between the Company and each
     Purchaser is "arms-length" and any statement made by any Purchaser or any
     of its representatives or agents in connection with this Agreement and the
     transactions contemplated hereby is merely incidental to such Purchaser's
     purchase of the Purchased Securities and has not been relied upon by the
     Company, its officers or directors in any

                                       8
<PAGE>   16

     way. The Company further acknowledges that the Company's decision to enter
     into this Agreement has been based solely on an independent evaluation by
     the Company and its representatives.

          SECTION 3.14.  Listing.  Prior to the Closing Date, the Company will
     secure the listing of the shares of Common Stock issuable upon conversion
     of the Preferred Shares and upon exercise of the Warrants upon each
     national securities exchange or automated quotation system upon which
     shares of Common Stock are currently listed (subject to official notice of
     issuance).

          SECTION 3.15.  Form S-3 Eligibility.  The Company is eligible to
     register the resale of its Common Stock on a registration statement on Form
     S-3 under the Securities Act. There exist no facts or circumstances that
     would prohibit or delay the preparation and filing of a registration
     statement on Form S-3 with respect to the Registrable Securities (as
     defined in the Registration Rights Agreement), other than notice
     requirements set forth in the Company's Registration Rights Agreements. The
     Company has no basis to believe that its past or present independent public
     auditors will withhold their consent to the inclusion, or incorporation by
     reference, of their audit opinion concerning the Company's financial
     statements which are included in the registration statement required to be
     filed pursuant to the Registration Rights Agreement.

          SECTION 3.16.  No General Solicitation.  Neither the Company nor any
     distributor participating on the Company's behalf in the transactions
     contemplated hereby (if any) nor any person acting for the Company, or any
     such distributor, has conducted any "general solicitation," as such term is
     defined in Regulation D, with respect to any of the Purchased Securities
     being offered hereby.

          SECTION 3.17.  No Integrated Offering.  Neither the Company, nor any
     of its affiliates, nor any person acting on its or their behalf, has
     directly or indirectly made any offers or sales of any security or
     solicited any offers to buy any security under circumstances that would
     require registration of the Purchased Securities being offered hereby under
     the Securities Act or cause this offering of Purchased Securities to be
     integrated with any prior offering of securities of the Company for
     purposes of the Securities Act, the result of such integration which would
     require registration under the Securities Act, or any applicable
     stockholder approval provisions, including, without limitation, Rule
     4350(i) of the NASD or any similar rule.

          SECTION 3.18.  No Brokers.  The Company has taken no action that would
     give rise to any claim by any person for brokerage commissions, finder's
     fees or similar payments by any Purchaser relating to this Agreement or the
     transactions contemplated hereby.

          SECTION 3.19.  Securities Laws.  The offer, issuance and sale of the
     Purchased Securities (including shares of Common Stock issuable upon
     conversion of the Preferred Shares and upon exercise of the Warrants), in
     each case without registration, will not violate the Securities Act, or any
     applicable state securities or "blue sky" laws.

          SECTION 3.20.  Title.  The Company and its subsidiaries have good and
     marketable title in fee simple to all real property and good and
     merchantable title to all personal property owned by them that is material
     to the business of the Company and its subsidiaries, in each case free and
     clear of all Liens, except such as do not materially affect the value of
     such property and do not materially interfere with the use made and
     proposed to be made of such property by the Company and its subsidiaries.
     Any real property and facilities held under lease by the Company and its
     subsidiaries are held by them under valid, subsisting and enforceable
     leases with such exceptions as are not material and do not materially
     interfere with the use made and proposed to be made of such property and
     buildings by the Company and its subsidiaries.

          SECTION 3.21.  Tax Status.  Except as set forth in the SEC Documents,
     the Company and each of its subsidiaries has made or filed all foreign,
     U.S. federal, state and local income and all other tax returns, reports and
     declarations required by any jurisdiction to which it is subject (unless
     and only to the extent that the Company and each of its subsidiaries has
     set aside on its books provisions reasonably adequate for the payment of
     all unpaid and unreported taxes) and has paid all taxes and other
     governmental assessments and charges that are material in amount, shown or
     determined to be due on

                                       9
<PAGE>   17

     such returns, reports and declarations, except those being contested in
     good faith and has set aside on its books provisions reasonably adequate
     for the payment of all taxes for periods subsequent to the periods to which
     such returns, reports or declarations apply. There are no unpaid taxes in
     any material amount claimed to be due by the taxing authority of any
     jurisdiction, and the officers of the Company know of no basis for any such
     claim. The Company has not executed a waiver with respect to any statute of
     limitations relating to the assessment or collection of any federal, state
     or local tax. None of the Company's tax returns is presently being audited
     by any taxing authority.

          SECTION 3.22.  Environmental Matters.  There is no environmental
     litigation or other environmental proceeding pending or threatened by any
     governmental regulatory authority or others with respect to the current or
     any former business of the Company or any partnership or joint venture
     currently or at any time affiliated with the Company. To the best knowledge
     of the Company, no state of facts exists as to environmental matters or
     Hazardous Substances (as defined below) that involves the reasonable
     likelihood of a material capital expenditure by the Company or that may
     otherwise have a Material Adverse Effect with respect to the Company. To
     the best knowledge of the Company, no Hazardous Substances have been
     treated, stored or disposed of, or otherwise deposited, in or on the
     properties owned or leased by the Company or by any partnership or joint
     venture currently or at any time affiliated with the Company in violation
     of any applicable environmental laws, during the time the Company has owned
     or leased such properties. The environmental compliance programs of the
     Company comply in all respects with all environmental laws, whether
     federal, state or local, currently in effect. As used herein, "HAZARDOUS
     SUBSTANCES" means any substance, waste, contaminant, pollutant or material
     that has been determined by any governmental authority to be capable of
     posing a risk of injury to health, safety, property or the environment.

          SECTION 3.23.  Insurance.  The Company has in force fire, casualty,
     product liability and other insurance policies, with extended coverage,
     sufficient in amount to allow it to replace any of its material properties
     or assets which might be damaged or destroyed or sufficient to cover
     liabilities to which the Company may reasonably become subject, and such
     types and amounts of other insurance with respect to its business and
     properties, on both a per occurrence and an aggregate basis, as are
     customarily carried by persons engaged in the same or similar business as
     the Company. No default or event has occurred that could give rise to a
     default under any such policy.

          SECTION 3.24.  Compliance With Laws.  The Company and its subsidiaries
     have complied with, are not in violation of, and have not received any
     notices of violation with respect to, any federal, state or local statute,
     law or regulation (including, without limitation, the Occupational Safety
     and Health Act and the Americans with Disabilities Act) with respect to the
     conduct of its business, or the ownership or operation of its business,
     except for failures to comply, violations or notices of violations which,
     individually or in the aggregate, do not have and are not reasonably likely
     to have a Material Adverse Effect with respect to the Company. Neither
     Company nor any of its subsidiaries has received any written notice of any
     actual, alleged or potential obligation on the part of Company or any of
     its subsidiaries to undertake, or to bear all or any portion of the cost
     of, any remedial action of any nature relating to the business of Company
     or any of its subsidiaries or their respective assets in connection with
     any violation or alleged violation of applicable law (including, without
     limitation, the Occupational Safety and Health Act and the Americans with

                                   ARTICLE IV

                          PURCHASERS' REPRESENTATIONS

     Each of the Purchasers hereby, severally and not jointly, represents and
warrants to the Company that:

          SECTION 4.1.  Investment Intent.  Such Purchaser is (i) an "accredited
     investor" as defined in Regulation D of the Securities Act and (ii)
     acquiring the Purchased Securities to be purchased by it pursuant to
     Article II hereof for investment and not with a view to the distribution
     thereof.

          SECTION 4.2.  Authorization.  The execution, delivery and performance
     by such Purchaser of this Agreement and of each Related Agreement to which
     such Purchaser is a party (a) are within such Purchaser's power and
     authority, (b) have been duly authorized by all necessary corporate,
     stockholder and other proceedings, as the case may be, and (c) do not and
     will not result in the creation of any Lien upon any of such Purchaser's
     property or conflict with or result in any breach of any provision of such
     Purchaser's Charter or by-laws or any Law, License, agreement or instrument
     to which such Purchaser is subject, other than those conflicts or breaches
     that are not reasonably expected to have a Material Adverse Effect with
     respect to such Purchaser.

          SECTION 4.3.  Enforceability.  This Agreement is and, when executed
     and delivered, each Related Agreement to which such Purchaser is a party
     will be, legally binding obligations of such Purchaser, enforceable against
     it in accordance with the respective terms and provisions hereof and
     thereof.

          SECTION 4.4.  Exemption.  Such Purchaser understands that the
     Purchased Securities are not, and any Common Stock acquired on conversion,
     exercise or otherwise pursuant to the terms thereof at the time of issuance
     will not be, registered under the Securities Act on the grounds that the
     sale provided for in this Agreement and the issuance of securities
     hereunder is exempt from registration under the Securities Act pursuant to
     section 4(2) thereof, and that the Company's reliance on such exemption is
     predicated on such Purchaser's representations set forth herein.

          SECTION 4.5.  Experience.  Such Purchaser is experienced in evaluating
     and investing in technology companies such as the Company, is familiar with
     the risks associated with the business and operations of companies that
     operate in similar lines of business, has such knowledge and experience in
     financial and business matters as to be capable of evaluating the merits
     and risks of its investment, and has the ability to bear the economic risks
     of its investment, including the potential loss of its investment. Such
     Purchaser represents that it has had, during the course of the transaction
     and prior to its purchase of the Purchased Securities, the opportunity to
     request information from and ask questions of the Company and its officers,
     employees and agents concerning the Company, its assets, business and
     operations and to receive information and answers to such requests and
     questions.

          SECTION 4.6.  Restrictions on Resale.  Such Purchaser understands that
     the Purchased Securities (and any Common Stock issued on conversion or
     exercise thereof) may not be sold, transferred, or otherwise disposed of
     without registration under the Securities Act or an exemption therefrom,
     and that in the absence of an effective registration statement covering the
     Purchased Securities (or the Common Stock issued on conversion or exercise
     thereof) or an available exemption from registration under the Securities
     Act, or sold under and in compliance with Rule 144 promulgated under the
     Securities Act (or a successor rule) ("RULE 144"), the Purchased Securities
     (and any Common Stock issued on conversion or exercise thereof) must be
     held indefinitely. Such Purchaser agrees that in no event will it make a
     transfer or disposition of any of the Purchased Securities or Common Stock
     issued upon conversion or exercise thereof (other than pursuant to an
     effective registration statement under the Securities Act), unless and
     until (i) such Purchaser shall have notified the Company of the proposed
     disposition and (ii) if requested by the Company, such Purchaser shall have
     furnished to the Company at the expense of such Purchaser or its
     transferee, an opinion of counsel reasonably satisfactory to the Company to
     the effect that such transfer may be made without registration under the
     Securities Act. Such Purchaser agrees that any certificate or instrument
     evidencing the Purchased Securities will contain a legend to such effect.

                                      11
<PAGE>   19

          SECTION 4.7.  Legends.  The Purchasers understand that the Purchased
     Securities and, until such time as the shares of Common Stock issuable upon
     conversion of the Preferred Shares and upon conversion of the Warrants have
     been registered under the Securities Act (including registration pursuant
     to Rule 416 thereunder) as contemplated by the Registration Rights
     Agreement or otherwise may be sold, and are being sold, by the Purchasers
     under Rule 144, the certificates for such shares of Common Stock may bear a
     restrictive legend in substantially the following form:

             The securities represented by this certificate have not been
        registered under the Securities Act of 1933, as amended, or the
        securities laws of any state of the United States or in any other
        jurisdiction. The securities represented hereby may not be offered, sold
        or transferred in the absence of an effective registration statement for
        the securities under applicable securities laws unless offered, sold or
        transferred pursuant to an available exemption from the registration
        requirements of those laws; provided the availability of such exemption
        is confirmed by an opinion of counsel, acceptable to the Company,
        delivered to the Company.

     The Company agrees that it shall, immediately prior to the Registration
Statement (as defined in the Registration Rights Agreement) being declared
effective, deliver to its transfer agent an opinion letter of counsel, opining
that at any time the Registration Statement is effective, the transfer agent
shall issue, in connection with the issuance of shares of Common Stock issuable
by the Company upon conversion of the Preferred Shares and upon exercise of the
Warrants, certificates representing such shares of Common Stock without the
restrictive legend above, provided such shares of Common Stock are to be sold
pursuant to the prospectus contained in the Registration Statement. Upon receipt
of such opinion, the Company shall cause the transfer agent to confirm, for the
benefit of the holders, that no further opinion of counsel is required at the
time of transfer in order to issue such shares without such restrictive legend.

     The legend set forth above shall be removed and the Company shall issue a
certificate without such legend to the holder of any security upon which it is
stamped, if, unless otherwise required by state securities laws, (a) the sale of
such security is registered under the Securities Act (including registration
pursuant to Rule 416 thereunder) as contemplated by the Registration Rights
Agreement; (b) such holder provides the Company with an opinion of counsel,
acceptable to the Company, in form, substance and scope customary for opinions
of counsel in comparable transactions, to the effect that a public sale or
transfer of such Security may be made without registration under the Securities
Act; or (c) such holder provides the Company with reasonable assurances that
such security can be sold under Rule 144. In the event the above legend is
removed from any security and thereafter the effectiveness of a registration
statement covering such security is suspended or the Company determines that a
supplement or amendment thereto is required by applicable securities laws, then
upon reasonable advance written notice to the Purchasers the Company may require
that the above legend be placed on any such security that cannot then be sold
pursuant to an effective registration statement or under Rule 144 and the
Purchasers shall cooperate in the replacement of such legend. Such legend shall
thereafter be removed when such security may again be sold pursuant to an
effective registration statement or under Rule 144.

                                   ARTICLE V

     SECTION 6.1.  Form D; Blue Sky Laws.  The Company shall file with the
Securities and Exchange Commission a Form D with respect to the Purchased
Securities as required under Regulation D and provide a copy thereof to the

pursuant to this Agreement under applicable securities or "blue sky" laws of the
states of the United States or obtain exemption therefrom, and shall provide
evidence of any such action so taken to the Purchasers on or prior to the
Closing Date.

     SECTION 6.2.  Reporting Status.  So long as any Purchaser beneficially owns
any of the Purchased Securities, the Company shall timely file all reports
required to be filed with the Securities and Exchange Commission pursuant to the
Securities Exchange Act, and the Company shall not terminate its status as an
issuer required to file reports under the Securities Exchange Act even if the
Securities Exchange Act or the rules and regulations thereunder would permit
such termination. In addition, the Company shall take all actions necessary to
meet the "registrant eligibility" requirements set forth in the general
instructions to Form S-3 or any successor form thereto, to continue to be
eligible to register the resale of its Common Stock on a registration statement
on Form S-3 under the Securities Act.

     SECTION 6.3.  Use of Proceeds.  The Company shall use the proceeds from the
sale of the Purchased Securities to pay Transaction Costs and for working
capital and general corporate purposes.

provided, however, that Purchasers shall be permitted to deduct all of their
respective Transaction Costs from the Purchase Price payable by such Purchaser
for the Purchased Securities purchased by such Purchaser hereunder (with prior
delivery to the Company of verifiable invoices for such Transaction Costs in
reasonable detail).

     SECTION 6.5.  Financial Information.  The Company shall send (via
electronic transmission or otherwise) the following reports to each Purchaser
until such Purchaser transfers, assigns or sells all of its Purchased
Securities: (i) within ten (10) days after the filing with the Securities and
Exchange Commission, a copy of its Annual Report on Form 10-K, its Quarterly
Reports on Form 10-Q, its proxy statements and any Current Reports on Form 8-K;
and (ii) within one (1) day after release, copies of all press releases issued
by the Company or any of its subsidiaries.

     SECTION 6.6.  Reservation of Shares.  The Company shall at all times have
authorized and reserved for the purpose of issuance a sufficient number of
shares of Common Stock to provide for the full conversion

                                      14
<PAGE>   22

of the Preferred Shares and issuance of the shares of Common Stock issuable upon
conversion pursuant to the terms thereof, and the full exercise of the Warrants
and issuance of the shares of Common Stock issuable upon exercise thereof and as
otherwise required by the Preferred Shares and the Warrants.

     SECTION 6.7.  Listing.  The Company shall maintain, so long as any
Purchaser (or any of its affiliates) owns any Purchased Securities, the listing
of all shares of Common Stock issuable upon conversion of the Preferred Shares
and upon exercise of the Warrants on each national securities exchange or
automated quotation system on which shares of Common Stock are currently listed.
The Company will use its best efforts to continue the listing and trading of its
Common Stock on NASDAQ, the New York Stock Exchange ("NYSE") or the American
Stock Exchange ("AMEX") and will comply in all respects with the reporting,
filing and other obligations under the bylaws or rules of the NASD and such
exchanges, as applicable. The Company shall promptly provide to the Purchasers
copies of any notices it receives regarding the continued eligibility of the
Common Stock for trading on the NASDAQ or, if applicable, any securities
exchange or automated quotation system on which securities of the same class or
series issued by the Company are then listed or quoted, if any.

     SECTION 6.8.  Corporate Existence.  So long as any Purchaser beneficially
owns any Purchased Securities, the Company shall maintain its corporate
existence, and in the event of a merger, consolidation or sale of all or
substantially all of the Company's assets, the Company shall ensure that the
surviving or successor entity in such transaction (i) assumes the Company's
obligations hereunder and under the Related Agreements regardless of whether or
not the Company would have had a sufficient number of shares of Common Stock
authorized and available for issuance in order to effect the conversion of all
the Preferred Shares and exercise in full of all Warrants outstanding as of the
date of such transaction and (ii) except in the event of a merger, consolidation
of the Company into any other corporation, or the sale or conveyance of all or
substantially all of the assets of the Company where the consideration consists
solely of cash, the surviving or successor entity is a publicly traded
corporation whose common stock is listed for trading on the NASDAQ, NYSE or
AMEX.

     SECTION 6.9.  No Integrated Offerings.  The Company shall not make any
offers or sales of any security (other than the Purchased Securities) under
circumstances that would require registration of the Purchased Securities being
offered or sold hereunder under the Securities Act or cause this offering of the
Purchased Securities to be integrated with any other offering of securities by
the Company for purposes of any stockholder approval provision applicable to the
Company or its securities.

     SECTION 6.10.  Legal Compliance.  The Company shall conduct its business
and the business of its subsidiaries in compliance with all laws, ordinances or
regulations of governmental entities applicable to such businesses, except where
the failure to do so would not have a Material Adverse Effect with respect to
the Company.

     SECTION 6.11.  Registration on Form S-3.  As soon as practical following
the Closing Date and the purchase of the Purchased Securities by the Purchasers,
but in no event later than 45 days following the Closing Date, the Company will
file with the SEC a registration statement on Form S-3 in order to register for
resale the shares of Common Stock issuable upon conversion or exercise of the
Purchased Securities and will take all commercially reasonable efforts to effect
such registration as soon as practicable thereafter. The Purchasers acknowledge
that the Company's filing of such registration statement will require prior
notice to existing stockholders who are parties to registration rights
agreements with the Company and that such stockholders may exercise their
"piggyback" registration rights to participate and include shares of Common
Stock they hold in such registration statement. The terms and conditions under
which such registration will be effected shall be as set forth in the
Registration Rights Agreement, except to the extent such terms and conditions
are inconsistent with the provisions of this Section 6.11.

     SECTION 6.12.  Conduct of Business.  From the date of this Agreement to the
Closing, the Company shall conduct its business, operations and activities only
in the ordinary course of business and consistent with past practice, and shall
cause all transactions relating thereto to be effected only in the ordinary
course of business.

<PAGE>   23

     SECTION 6.13.  Board Seats.  The Company shall use its best efforts,
between the signing of this Agreement and the Closing Date, to obtain the
written approval of the Nasdaq Stock Market or its Staff, under Rule 4351 of the
NASD or such other rules as may apply, for an amendment to the Certificate of
Designation providing for the right of the holders of the Preferred Shares to
elect two (2) members of the Company's Board of Directors ("DIRECTORS") so long
as there is outstanding any of the Preferred Shares originally issued on the
Closing Date, one of which shall be designated by SCP Private Equity Partners,
II, L.P. so long as it holds any of such Preferred Shares and one of which shall
be designated by Tandem PCS Investments, L.P. so long as it holds any of such
Preferred Shares, and if such approval is obtained, the Certificate of
Designation shall be so amended by the Company before its filing with the
Delaware Secretary of State.

     SECTION 6.14.  Subsequent Offering.  The Company agrees that without the
prior written consent of each of the Purchasers, it will not issue additional
shares of the Series B Convertible Preferred Stock at a price per share less
than $31.40 or on terms more favorable to the purchasers of such additional
shares than the terms contemplated hereby and by the Certificate of Designation.

                                  ARTICLE VII

                          TRANSFER AGENT INSTRUCTIONS

     (a) The Company shall instruct its transfer agent to issue certificates,
registered in the name of the Purchasers or their nominee, for the shares of
Common Stock issuable upon conversion of the Preferred Shares and upon exercise
of the Warrants in such amounts as specified from time to time by the Purchasers
to the Company upon conversion of or otherwise pursuant to the Preferred Shares
or upon exercise of the Warrants, as applicable.

     (b) The Company warrants that no instruction other than such instructions
referred to in this Article VII, and stop transfer instructions to give effect
to SECTION 4.7 hereof in the case of the transfer of the shares of Common Stock
issuable upon conversion of the Preferred Shares or upon exercise of the
Warrants prior to registration of such shares of Common Stock under the
Securities Act or without an exemption therefrom, will be given by the Company
to its transfer agent and that such securities shall otherwise be freely
transferable on the books and records of the Company as and to the extent
provided in this Agreement and the Registration Rights Agreement and permitted
under applicable securities laws. Nothing in this Article VII shall affect in
any way the Purchasers' obligations and agreement set forth in SECTION 4.7
hereof to resell such securities pursuant to an effective registration statement
or under an exemption from the registration requirements of applicable
securities law.

     (c) If any Purchaser provides the Company and the transfer agent with an
opinion of counsel reasonably satisfactory to the Company, which opinion of
counsel shall be in form, substance and scope customary for opinions of counsel
in comparable transactions, to the effect that the shares of Common Stock
issuable upon conversion of the Preferred Shares or upon exercise of the
Warrants to be sold or transferred may be sold or transferred pursuant to an
exemption from registration, the Company shall permit the transfer and, in the
case of shares of Common Stock issuable upon conversion of the Preferred Shares
or upon exercise of the Warrants, promptly instruct its transfer agent to issue
one or more certificates in such name and in such denominations as specified by
such Purchaser.

                                  ARTICLE VIII

                   SUBSEQUENT HOLDERS OF PURCHASED SECURITIES

     Whether or not any express assignment has been made in this Agreement, the
provisions of this Agreement that are for the benefit of the Purchasers as the
holders of any Purchased Securities are also for the benefit of, and enforceable
by, all subsequent holders of such Purchased Securities, and the provisions of
this Agreement that subject the Purchasers to obligations as the holders of any
Purchased Securities also shall subject all subsequent holders of Purchased
Securities.

                                   ARTICLE X

                                   INDEMNITY

     SECTION 10.1.  Indemnification.  Notwithstanding any disclosures made in
the Schedules hereto, the Company hereby agrees to indemnify, exonerate and hold
the Purchasers and their (if applicable) general and limited partners, members
and managers, or shareholders and their respective shareholders, officers,
directors, employees and agents (each an "INDEMNITEE") free and harmless from
and against any and all actions, causes of action, or suits (the "CLAIMS"),
losses, liabilities, damages and expenses, including, without limitation,
reasonable attorneys' fees and disbursements (collectively, "DAMAGES") arising
from a breach of any representation, warranty, covenant or agreement of the
Company contained in or made pursuant to this Agreement or any of the Related
Agreements, and (b) any Claims brought against them by third parties ("THIRD
PARTY CLAIMS") to the extent any such Third Party Claim is incurred by any
Indemnitee as a result of or relating to (i) any transaction by the Company
financed or to be financed in whole or in part, directly or indirectly, with
proceeds from the sale of any of the Purchased Securities, and (ii) the
execution, delivery, performance or enforcement of this Agreement, the Related
Agreements or any other agreement contemplated hereby or thereby (including,
without limitation, any failure by the Company to comply with any of its
covenants or any material breach of its representations and warranties in this
Agreement, the Related Agreements or any other agreement contemplated hereby or
thereby), excluding, however, any such Damages caused directly by the actions of
the Indemnitee in violation of its obligations under such agreements.

     SECTION 10.2.  Transaction Costs.  The Company hereby agrees to indemnify
each Purchaser against and agrees that it will hold each Purchaser harmless from
any claim, demand or liability for any

                                      17
<PAGE>   25

Transaction Costs incurred by the Company or such Purchaser in connection with
the transactions contemplated by this Agreement or the Related Agreements.

     SECTION 10.3.  Procedures.

     (a) In the event of any Third Party Claim for indemnification under the
terms of SECTION 10.1 or 10.2, Indemnitee shall give prompt written notice of
such Third Party Claim to the Company which may assume the defense thereof,
provided that any delay or failure to so notify the Company shall relieve the
Company of its obligations hereunder only to the extent, if at all, that it is
materially prejudiced by reason of such delay or failure. The Indemnitee shall
have the right to approve any counsel selected by the Company and to approve the
terms of any proposed settlement, such approval not to be unreasonably delayed
or withheld (unless, in the case of approval of a proposed settlement, such
settlement provides only, as to the Indemnitee, the payment of money damages
actually paid by the Company and a complete release of the Indemnitee in respect
of the Third Party Claim in question). Notwithstanding any of the foregoing to
the contrary, the provisions of this ARTICLE X shall not be construed so as to
provide for the indemnification of any Indemnitee for any liability to the
extent (but only to the extent) that such indemnification would be in violation
of applicable law or that such liability may not be waived, modified or limited
under applicable law, but shall be construed so as to effectuate the provisions
of this ARTICLE X to the fullest extent permitted by law.

     (b) In the event that the Company undertakes the defense of any Third Party
Claim, the Company will keep the Indemnitee advised as to all material
developments in connection with such Third Party Claim, including, but not
limited to, promptly furnishing the Indemnitee with copies of all material
documents filed or served in connection therewith.

     (c) In the event that the Company fails to assume the defense of any Third
Party Claim within ten Business Days after receiving written notice thereof, the
Indemnitee shall have the right, subject to the Company's right to assume the
defense pursuant to the provisions of this ARTICLE X, to undertake the defense,
compromise or settlement of such Third Party Claim for the account of the
Company. Unless and until the Indemnitee assumes the defense of any Third Party
Claim, the Company shall advance to the Indemnitee any of its reasonable
attorneys' fees and other costs and expenses incurred in connection with the
defense of any such action or proceeding. In addition, if the Indemnitee has
notified the Company of its determination that such Third Party Claim may
reasonably create a conflict between the positions of the Indemnitee and the
Company, then separate counsel shall be entitled to participate in and conduct
such defense and the Company shall be liable for any reasonable legal or other
expenses incurred by the Indemnitee in connection with such defense. Each
Indemnitee shall agree in writing prior to any such advancement that, in the
event he or it receives any such advance, such Indemnitee shall reimburse the
Company for such fees, costs and expenses to the extent that it shall be
determined that he or it was not entitled to indemnification under this ARTICLE
X.

     (d) In no event shall Company be required to pay in connection with any
Third Party Claim for more than one firm of counsel (and local counsel) to the
Purchasers, their Affiliates, directors, shareholders, officers, employees,
agents and/or the legal representatives of any of them.

     SECTION 10.4.  Survival of Obligations.  The obligations of the Company and
the Purchasers under this ARTICLE X shall survive the Closing Date and the
termination of this Agreement.

                                   ARTICLE XI

set forth herein, this Agreement may be terminated, and the transactions
contemplated hereby may be abandoned, without further obligation of any party
(except as set forth herein), at any time prior to the Closing Date:

          (a) by mutual written consent of the parties;

          (c) by the Company, upon written notice to the Purchasers on or before

     otherwise in breach of this Agreement) if (i) the Company has breached a
     material representation, warranty, covenant or agreement set forth herein,
     (ii) such breach would entitle the Purchasers not to consummate the
     transactions at the Closing and (iii) the Company fails to cure such breach
     within ten (10) days of written notice thereof from any Purchaser and (y)
     the Company as to any Purchaser (provided that the Company is not otherwise
     in breach of this Agreement) if (i) such Purchaser has breached a material
     representation, warranty, covenant or agreement set forth herein, (ii) such
     breach would entitle the Company not to

                                      19
<PAGE>   27

     consummate the transactions at the Closing and (iii) such Purchaser fails
     to cure such breach within ten (10) days of written notice thereof from the
     Company.

     SECTION 12.2.  Effect of Termination.  In the event of a termination of
this Agreement, neither party hereto shall have any liability or further
obligation to the other party, except as set forth in paragraph (a), (b) or (c)
below, and except that nothing herein will relieve any party from liability for
any breach by such party of this Agreement.

     (a) In the event of a termination by the Company of this Agreement pursuant
to SECTION 12.1, all provisions of this Agreement shall terminate, except
ARTICLES X, XI, XII, XIV and XV.

     (b) Except in the event of a termination by the Company pursuant to SECTION

     SECTION 12.3.  Survival.  All covenants, agreements, representations and
warranties made herein or in any other document referred to herein or delivered

Agreements shall survive the execution and delivery of this Agreement and of the
Purchased Securities for three (3) years from the Closing Date.

                                  ARTICLE XIII

                             AMENDMENTS AND WAIVERS

     This Agreement may be amended and the observance of any term of this
Agreement may be waived (either generally or in a particular instance and either
retroactively or prospectively and either for a specified period of time or
indefinitely) only with the written consent of the Company and each of the
Purchasers. Any amendment or waiver effected in accordance with this ARTICLE
XIII shall be binding upon the Company and each holder (or permitted transferee)
of any Purchased Securities sold pursuant to this Agreement (whether or not such
holder (or permitted transferee) has consented to such amendment or waiver).

                                  ARTICLE XIV

                   CHOICE OF LAW; SUBMISSION TO JURISDICTION
                            AND WAIVER OF JURY TRIAL

     SECTION 14.1.  Governing Law.  THIS AGREEMENT SHALL BE CONSTRUED AND
ENFORCED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF FLORIDA
(WITHOUT GIVING EFFECT TO ANY CONFLICTS OR CHOICE OF LAWS PROVISIONS THAT WOULD
CAUSE THE APPLICATION OF THE DOMESTIC SUBSTANTIVE LAWS OF ANY OTHER

     SECTION 14.2.  Equitable Remedies.  The parties hereto agree that
irreparable harm would occur in the event that any of the agreements and
provisions of this Agreement were not performed fully by the parties hereto in
accordance with their specific terms or conditions or were otherwise breached,
and that money damages are an inadequate remedy for breach of this Agreement
because of the difficulty of ascertaining and quantifying the amount of damage
that will be suffered by the parties hereto in the event that this Agreement is
not performed in accordance with its terms or conditions or is otherwise
breached. It is accordingly hereby agreed that the parties hereto shall be
entitled to an injunction or injunctions to restrain, enjoin and prevent
breaches of this Agreement by the other parties and to enforce specifically such
terms and provisions of this

                                     20

Agreement in any court of the United States or any state having jurisdiction,
such remedy being in addition to and not in lieu of, any other rights and
remedies to which the other parties are entitled to at law or in equity.

                                   ARTICLE XV

                      CONFIDENTIALITY; RIGHT TO PUBLICIZE

     (a) Each Purchaser, on behalf of itself and its Affiliates, agrees that it
will maintain the confidentiality of all non-public information disclosed to it
by the Company or obtained as a result of negotiating or entering into this
Agreement and the Related Agreement and will not, without the prior written
consent of the Company, use such information other than in connection with the
transactions contemplated hereby, provided, however, that the foregoing
confidentiality obligations do not apply to information that (i) was or becomes
available to the public through no action by such Purchaser, (ii) was or becomes
available to such Purchaser on a non-confidential basis or (iii) in the
reasonable opinion of legal counsel, must be disclosed pursuant to Law or the
requirements of any national securities exchange; provided further, however,
that in the case of (iii) above where disclosure is sought pursuant to subpoena,
litigation discovery request or other similar legal process, such Purchaser
shall submit the proposed disclosure to the Company, who shall have an
opportunity, at its expense, to contest such disclosure, move for a protective
order or otherwise attempt to narrow the scope thereof to the extent permitted
under Law.

     (b) Each of the parties hereto hereby agrees that it will not, except as
required by law, issue a press release or make any public statement regarding
the transactions contemplated hereby without the prior approval of the Company
and the Purchasers; provided, however, that following the Closing but only after
the final closing by the Company of the sale of any other shares of Series B
Convertible Preferred Stock and warrants to purchase shares of Common Stock, the
Purchasers will have the right to publicize their investment in the Company as
contemplated hereby by means of a tombstone advertisement or other customary
advertisement in newspapers and other periodicals which advertisement shall be
reasonably acceptable to the Company and customary disclosures to its limited
partners. The Company will announce and disclose to the public and in applicable
SEC filings the material terms of this Agreement and the Related Agreements
promptly following execution of this Agreement and will have the right to inform
actual or prospective customers and lenders of such investment from and after
the date of this Agreement.

                                  ARTICLE XVI

                ENTIRE AGREEMENT; COUNTERPARTS; SECTION HEADINGS

or written) between the parties with respect to its subject matter.

     (b) This Agreement may be executed in any number of counterparts, each of
which shall be deemed an original, but all of which together shall constitute
one and the same instrument.

     (c) There are no third party beneficiaries of this Agreement.

     (d) In case any provision of this Agreement shall be invalid, illegal or
unenforceable, the validity, legality and enforceability of the remaining
provisions of this Agreement shall not in any way be affected or impaired
thereby.

Incorporation"), the Board of Directors does hereby create, authorize and
provide for the issuance of Series B Convertible Preferred Stock, par value $.01
per share, consisting of 3,184,713 shares, having the following designations,
preferences and relative and other special rights, qualifications, limitations
and restrictions:

          1.  DESIGNATION AND AMOUNT.  The designation of such series is "SERIES
     B CONVERTIBLE PREFERRED STOCK" (hereinafter in this Certificate of
     Designation called the "SERIES B PREFERRED STOCK") and the number of shares
     constituting such series shall be 3,184,713, which number may be decreased
     (but not increased) by the Board of Directors without a vote of
     stockholders; provided, however, that such number may not be decreased
     below the number of then currently outstanding shares of Series B Preferred
     Stock, plus shares issuable upon the exercise of any then outstanding
     options, warrants or rights to acquire Series B Preferred Stock, including
     dividends payable pursuant to the terms of the Series B Preferred Stock.
     All capitalized terms used in this Certificate of Designation and not
     otherwise defined shall have the meaning given to such terms in Section 13
     hereof.

          2.  DIVIDENDS.  (a) The Holders of shares of the Series B Preferred
     Stock, in preference to the holders of all Junior Capital Stock and on a
     pari passu basis with holders of Parity Capital Stock, will be entitled to
     receive, when, as and if dividends are declared by the Board of Directors,
     out of funds of the Corporation legally available therefor, cumulative
     dividends as provided in this Section 2. Dividends on each outstanding
     share of Series B Preferred Stock shall be payable in cash, or at the
     option of the Corporation, in such number of shares of Series B Preferred
     Stock as is set forth in Section 2(d) below, and accrue (whether or not
     earned or declared) at the rate of 8% per annum on the sum of (i) the
     Purchase Price and (ii) all accumulated and unpaid dividends accrued
     thereon from the date of issuance thereof (the "SERIES B DIVIDENDS"). Such
     dividends will be calculated and accrued on a quarterly basis on the last
     day of each fiscal quarter of the Corporation in respect of the prior three
     month period prorated on a daily basis for partial periods.

          (b) If the Corporation at any time pays less than the total amount of
     Series B Dividends then accrued with respect to the Series B Preferred
     Stock, such payment shall be distributed ratably among the Holders based
     upon the aggregate accrued but unpaid Series B Dividends on the Series B
     Preferred Stock held by each such Holder.

                                       1
<PAGE>   33

          (c) In the event that the Corporation declares or pays any dividends
     upon the Common Stock (whether payable in cash, securities or other
     property) other than dividends payable solely in shares of Common Stock,
     the Corporation shall also declare and pay to the Holders at the same time
     that it declares and pays such dividends to the holders of the Common
     Stock, the dividends which would have been declared and paid with respect
     to the Series B Preferred Stock had all of the outstanding Series B
     Preferred Stock been converted in accordance with Section 6(a) immediately
     prior to the record date for such dividend, or if no record date is fixed,
     the date as of which the record holders of Common Stock entitled to such
     dividends are to be determined.

          (d) The Corporation may pay the Series B Dividends to each Holder by
     the issuance of such number of shares of Series B Preferred Stock as equals
     the quotient of (i) the accrued and unpaid Series B Dividends with respect
     to the shares of Series B Preferred Stock held such Holder and (ii) the
     Purchase Price.

          3.  LIQUIDATION PREFERENCE.  (a) In the event of any (each a
     "LIQUIDATION EVENT") liquidation, dissolution or winding up of the affairs
     of the Corporation, either voluntarily or involuntarily, each Holder shall
     be entitled, after payment of the Corporation's debts and other liabilities
     and any preferential amounts due to the holders of Senior Capital Stock, to
     be paid in full, before any distribution is made on any Junior Capital
     Stock but on a pari passu basis with any distribution on Parity Capital
     Stock, an amount (the "LIQUIDATION AMOUNT") with respect to each share of
     Series B Preferred Stock held by such Holder equal to the sum of (i) the
     product of (x) the Purchase Price and (y) two and (ii) the Series B
     Dividends accrued on such share of Series B Preferred Stock. After payment
     of the preferences to all holders of preferred stock of the Corporation,
     all remaining assets of the Corporation legally available for distribution,
     if any, shall be distributed ratably to the holders of the Common Stock,
     Series B Preferred Stock (on an as-if converted to Common Stock basis) and
     any other Capital Stock of the Corporation entitled to share in such
     distribution.

          (b) Deemed Liquidation.  The Majority Holders may elect in writing by
     notice delivered to the Corporation, prior to the closing of a Sale of the
     Corporation, to treat a specific proposed Sale of the Corporation (other
     than a Qualified Sale of the Corporation) as a Liquidation Event for
     purposes of Section 3(a).

          (c) Partial Payment.  The Corporation shall, not later than 20 days
     prior to the earlier of the record date for the taking of a vote of
     stockholders with respect to any Liquidation Event or the date set for the
     consummation of a Liquidation Event, provide to the Holders such
     information concerning the terms of the Liquidation Event and the value of
     the assets of the Corporation or such other relevant information as may be
     reasonably requested by the Holders. If, upon a Liquidation Event, the net
     assets of the Corporation available for payment to the Holders of Series B
     Preferred Stock and the holders of Parity Capital Stock are not sufficient
     to pay in full the Liquidation Amount to the Holders of Series B Preferred
     Stock and the preferential amounts due to the holders of Parity Capital
     Stock, the Holders of Series B Preferred Stock and the holders of Parity
     Capital Stock shall share equally and ratably in any distribution of assets
     of the Corporation in proportion to the full liquidation preference to
     which each is entitled.

          (d) No Additional Distributions.  Holders of Series B Preferred Stock
     shall not be entitled to any additional distribution in the event of any
     Liquidation Event in excess of the amount set forth in Section 3(a) hereof.

          4.  VOTING RIGHTS OF SERIES B PREFERRED STOCK.  (a) Except as
     otherwise required by law or as provided herein, each Holder of Series B
     Preferred Stock shall be entitled to vote on all matters and shall be
     entitled to that number of votes equal to the number of shares of Common
     Stock into which such Holder's shares could be converted pursuant to the
     provisions of Section 6(a) hereof on the record date for the determination
     of stockholders entitled to vote on such matter or, if no such record date
     is established, on the date such vote is taken or any written consent of
     stockholders is solicited, provided, however, that, solely for purposes of
     determining the number of votes a Holder of Series B Preferred Stock is
     entitled to pursuant to this Section 4, the Conversion Price (as defined in
     Section 6(d) hereof),

                                       2
<PAGE>   34

     if then less than $2.8438, shall be deemed to be $2.8438 (the shares deemed
     convertible for purposes of such determination shall be hereinafter
     referred to as the "Holders' Voting Shares"). Except as otherwise expressly
     provided herein or as required by law, the Holders of shares of the Series
     B Preferred Stock shall vote together with the holders of shares of the
     Corporation's Common Stock as a single class on all matters. The Holders
     shall be entitled to notice of all stockholders meetings in accordance with
     the Corporation's by-laws and General Corporation Law of the State of
     Delaware.

          (b) Notwithstanding the above paragraph or any provision to the
     contrary contained herein, the Holders of Series B Preferred Stock shall be
     entitled, voting together as a separate single class, to nominate, and upon
     amendment of the Corporation's Certificate of Incorporation as described
     below to elect, two (2) members of the Board of Directors in accordance
     with the terms set forth in this Section 4(b) and subject to the
     limitations set forth in Section 4(c) below. Until such time as the
     Corporation's stockholders have approved an amendment to the Corporation's
     Certificate of Incorporation (the "Charter Amendment") providing for the
     right of the Holders of Series B Preferred Stock to elect two (2) members
     of the Board of Directors and such Charter Amendment is filed with the
     Delaware Secretary of State and effective (the "Charter Amendment Effective
     Date") and subject to the limitations set forth in Section 4(c) below, the
     Holders of Series B Preferred Stock, voting together as a separate single
     class, are entitled to designate two (2) nominees for election to the class
     of the Board of Directors whose term expires at the Corporation's 2001
     Annual Stockholders Meeting ("Class III") and at each subsequent election
     of Class III directors prior to the Charter Amendment Effective Date, and
     the Board of Directors shall nominate such designees and recommend to the
     Corporation's stockholders that such designees be elected as members of
     Class III of the Board of Directors.

          With respect to the two (2) directors to be designated for nomination
     by the Holders of Series B Preferred Stock, one individual shall be
     designated by SCP Private Equity Partners II, L.P. ("SCP") so long as SCP
     holds any Series B Preferred Stock (the "SCP Designee for Nomination") and
     one individual shall be designated by Tandem PCS Investments, L.P.
     ("Tandem") so long as Tandem holds any Series B Preferred Stock (the
     "Tandem Designee for Nomination"). For nominees for election at the
     Corporation's 2001 Annual Stockholders Meeting, each of SCP and Tandem
     shall notify the Corporation in writing of the identity of its designee no
     later than ten (10) days following the date on which they become Holders of
     Series B Preferred Stock. For all subsequent elections of Class III
     directors, each of SCP and Tandem shall notify the Corporation in writing
     of the identity of its designee for nomination to Class III of the Board of
     Directors no later than the last date (the "Designee Notice Due Date") on
     which shareholder proposals may be submitted for an election year when they
     have such a right, which notice shall be conclusive evidence of the consent
     of such designee to serve as a director of the Corporation. In the event
     either SCP or Tandem fails to provide such notice, the SCP Designee for
     Nomination and Tandem Designee for Nomination (or the SCP representative
     and Tandem representative in the case of the notice for the Corporation's
     2001 Annual Stockholders' Meeting) serving on the Board of Directors on the
     Designee Notice Due Date shall be deemed to be renominated. In the event
     SCP or Tandem has no designee serving (or otherwise designated to serve in
     the event of the resignation, death, removal or inability to serve of a
     designee, as provided in the last sentence of this paragraph) on the Board
     of Directors on the Designee Notice Due Date, the Board of Directors shall
     be entitled to make the nomination for which such notice was required. In
     the event either SCP or Tandem fails to hold any Series B Preferred Stock,
     the Holders of Series B Preferred Stock, voting together as a separate
     single class, shall be entitled to the director nomination rights
     previously held by SCP or Tandem, as the case may be. If neither SCP nor
     Tandem holds any Series B Preferred Stock, the Holders of Series B
     Preferred Stock, voting together as a separate single class, shall be
     entitled to the director nomination rights previously held by SCP and
     Tandem. The notice shall include all information with respect to such
     designee as is required to be included in a proxy statement soliciting
     proxies for the election of directors pursuant to Regulation 14A of the
     Exchange Act. In the event of any vacancy arising by reason of the
     resignation, death, removal (which may include a removal by the Holders of
     Series B Preferred Stock, with or without cause, at the written request of
     SCP or Tandem, as applicable, as the party designating such director) or
     inability to serve of the SCP Designee for Nomination or the Tandem
     Designee for Nomination, SCP or Tandem, as applicable, shall notify the
     Corporation of its choice to fill such vacancy,

                                       3
<PAGE>   35

     and the Board of Directors shall appoint such person to fill such vacancy
     and serve until the next meeting of the Corporation's stockholders for the
     election of Class III directors.

          At all times after the Charter Amendment Effective Date and subject to
     the limitations set forth in Section 4(c) below, the Holders of Series B
     Preferred Stock, voting together as a separate single class, shall be
     entitled to elect two (2) members of Class III of the Board of Directors at
     each election of Class III directors. With respect to the two (2) directors
     to be designated for election by the Holders of Series B Preferred Stock,
     one individual shall be designated by SCP so long as SCP holds any Series B
     Preferred Stock (the "SCP Designee for Election") and one individual shall
     be designated by Tandem so long as Tandem holds any Series B Preferred
     Stock (the "Tandem Designee for Election"). Each of SCP and Tandem shall
     notify the Corporation in writing of the identity of its designee for
     election to Class III of the Board of Directors no later than the Designee
     Notice Due Date, which notice shall be conclusive evidence of the consent
     of such designee to serve as a director of the Corporation. In the event
     either SCP or Tandem fails to provide such notice, the SCP designee and
     Tandem designee serving on the Board of Directors on the Designee Notice
     Due Date shall be deemed to be the applicable designee. In the event either
     SCP or Tandem has no designee serving (or otherwise designated to serve in
     the event of the resignation, death, removal or inability to serve of a
     designee, as provided in the last sentence of this paragraph) on the Board
     of Directors on the Designee Notice Due Date, the Board of Directors shall
     be entitled to make the nomination for which such notice was required. In
     the event SCP or Tandem fails to hold any Series B Preferred Stock, the
     Holders of Series B Preferred Stock, voting together as a separate single
     class, shall be entitled to the director election rights previously held by
     SCP or Tandem, as the case may be. If neither SCP nor Tandem holds any
     Series B Preferred Stock, the Holders of Series B Preferred Stock, voting
     together as a separate single class, shall be entitled to the director
     election rights previously held by SCP and Tandem. The notice shall include
     all information with respect to such designee as is required to be included
     in a proxy statement soliciting proxies for the election of directors
     pursuant to Regulation 14A of the Exchange Act. In the event of any vacancy
     arising by reason of the resignation, death, removal (which may include a
     removal by the Holders of Series B Preferred Stock, with or without cause,
     at the written request of SCP or Tandem, as applicable, as the party
     designating such director) or inability to serve of the SCP Designee for
     Election or the Tandem Designee for Election, SCP or Tandem, as applicable
     (provided SCP or Tandem, as applicable, then holds Series B Preferred
     Stock) shall notify the Corporation of its choice to fill such vacancy, and
     the Board of Directors shall appoint such person to fill such vacancy and
     serve until the next meeting of the Corporation's stockholders for the
     election of Class III directors.

          The class voting rights granted to the Holders of Series B Preferred
     Stock pursuant to this Section 4(b) shall be in addition to, and not in
     lieu of, the voting rights granted to such Holders under Section 4(a)
     hereof. Accordingly, the Holders of Series B Preferred Stock shall be
     entitled to vote together with the holders of shares of the Corporation's
     Common Stock as a single class with respect to the election of those
     directors for which the Holders do not have class voting rights.

          (c) Notwithstanding the provisions of Section 4(b) above, the class
     voting rights to which the Holders of Series B Preferred Stock are entitled
     pursuant to such section shall be limited, and in certain cases eliminated,
     in the event the Holders of Series B Preferred Stock fail to maintain
     certain threshold levels of ownership of the Corporation's voting
     securities, as set forth below. In the event the sum of (i) the Holders'
     Voting Shares, plus (ii) the shares of Common Stock issued and outstanding
     and owned by the Holders (the total of such shares from time to time is
     hereinafter referred to as the "Holders' Share Total" and with respect to a
     specific Holder, a "Share Total") constitutes less than 15% of the sum of
     (i) the Corporation's outstanding shares of Common Stock plus (ii) the
     Holders' Voting Shares (the total of such shares is hereinafter referred to
     as the "Deemed Outstanding Shares") on a Designee Notice Due Date, the
     Holders of Series B Preferred Stock shall be entitled to only one designee
     for nomination or election, as the case may be, with respect to such
     election. In such case, SCP or Tandem, whichever entity has a higher Share
     Total, shall be entitled to make such designation. In the event, SCP and
     Tandem have equal Share Totals on a Designee Notice Due Date on which the
     Holders are entitled to only one designee, SCP and Tandem shall agree on a
     mutually acceptable designee. In the event the

                                       4
<PAGE>   36

     Holders' Share Total constitutes less than 10% of the Deemed Outstanding
     Shares on a Designee Notice Due Date, the Holders of Series B Preferred
     Stock shall not be entitled to designate a director for such election and
     the Holders shall be entitled to voting rights in accordance with Section
     4(a) above with respect to such election.

          5.  RESTRICTED ACTIONS.  (a) The affirmative vote of the Majority
     Holders, acting by written consent as a separate class or voting separately
     as a separate class, shall be necessary to authorize the Corporation or any
     Subsidiary of the Corporation to take any of the following actions:

             (i) authorize, create, issue, modify the material terms of, or
        change the amount of authorized or issued shares of, any Senior Capital
        Stock (or any securities convertible into or exchangeable for any Senior
        Capital Stock) or Indebtedness that by its terms is convertible or
        exchangeable into Senior Capital Stock (or any securities convertible
        into or exchangeable for Senior Capital Stock;

             (ii) effect (x) any Sale of the Corporation other than a Qualified
        Sale of the Corporation or a Qualified Public Offering or (y) any
        Reorganization of the Corporation;

             (iii) alter the rights, preferences or privileges of the Series B
        Preferred Stock;

             (iv) increase the authorized number of shares of Series B Preferred
        Stock;

             (v) redeem, purchase or otherwise acquire any shares of Common
        Stock or Preferred Stock (or pay into a sinking fund for such purpose);
        provided, however, that this restriction shall not apply to any
        redemption specifically permitted pursuant to this Certificate of
        Designation or to the repurchase of shares of Common Stock at the
        original purchase price from employees, officers, directors or other
        persons performing services for the Corporation.

          (b) Notwithstanding the foregoing provisions of this Section 5 and
     except as otherwise required by law, the creation, authorization or
     issuance of any shares of any Junior Capital Stock or Parity Capital Stock,
     or the increase or decrease in the amount of authorized Junior Capital
     Stock or Parity Capital Stock of any class shall not require the
     affirmative vote or consent of the Majority Holders and shall not be deemed
     to materially affect adversely the rights, preferences, privileges or
     voting rights of shares of Series B Preferred Stock.

          (c) In any case in which the Holders of Series B Preferred Stock shall
     be entitled to vote (as Holders of Series B Preferred Stock rather than on
     an as-if-converted basis) pursuant hereto or pursuant to the General
     Corporation Law of the State of Delaware, each Holder of Series B Preferred
     Stock entitled to vote with respect to such matters shall be entitled to
     one vote for each share of Series B Preferred Stock held.

     6.  CONVERSION RIGHTS.

          (a) Optional Conversion. At any time and from time to time, any Holder
     shall have the right, at its option, to convert all or any portion of the
     shares of Series B Preferred Stock (including all accrued dividends paid or
     payable in shares of Series B Preferred Stock and any fraction of a share)
     held by such Holder into such number of shares of fully paid and
     nonassessable Common Stock as equals the product of (i) the number of
     shares of Series B Preferred Stock to be converted by such Holder and (ii)
     the quotient of (x) the Purchase Price and (y) the Conversion Price in
     effect on the Conversion Date. Each optional conversion of Series B
     Preferred Stock shall be deemed to have been effected as of the close of
     business on the effective date of such conversion specified in a written
     notice by such Holder to the Corporation (the "CONVERSION DATE"); provided,
     however, that the Conversion Date shall not be a date earlier than the date
     such notice is so given, and if such notice does not specify a conversion
     date, the Conversion Date shall be deemed to be the date such notice is
     given to the Corporation. On the Conversion Date, the rights of the holder
     of such Series B Preferred Stock as such Holder shall cease and the Person
     or Persons in whose name or names any certificate or certificates for
     shares of Common Stock are to be issued upon such conversion shall be
     deemed to have become the holder or holders of record of the shares of
     Common Stock represented thereby. Notwithstanding any other provision
     hereof, if a voluntary conversion of Series B Preferred Stock is to be made
     in connection with a public offering other

                                       5
<PAGE>   37

     than a Qualified Public Offering or a Sale of the Corporation other than a
     Qualified Sale of the Corporation, such conversion may, at the election of
     the Holder, be conditioned upon the consummation of the respective public
     offering or Sale of the Corporation, in which case such conversion shall
     not be deemed to be effective until the closing of such public offering or
     Sale of the Corporation, as the case may be.

          (b) Mandatory Conversion.  Immediately upon any Mandatory Conversion
     Event, all shares of Series B Preferred Stock held by each Holder
     (including all accrued dividends paid or payable in shares of Series B
     Preferred Stock and any fraction of a share of Series B Preferred Stock)
     shall automatically be converted into the number of fully paid and
     nonassessable shares of Common Stock of the Corporation as equals the
     product of (i) the number of shares of Series B Preferred Stock held by
     such Holder and (ii) the quotient of (x) the Purchase Price and (y) the
     Conversion Price in effect on the Conversion Date. A "MANDATORY CONVERSION
     EVENT" shall mean (A) the closing of a Qualified Public Offering; (B) the
     closing of a Qualified Sale of the Corporation or (C) the written election
     of the Majority Holders, including each Lead Investor.

         (c) Conversion Procedure.

             (i) Delivery of Certificates.  As soon as practicable after any
        conversion of Series B Preferred Stock pursuant to this Section 6, but
        in any event within ten (10) business days after the holder has
        delivered the certificates or affidavits of loss, if applicable,
        evidencing the shares of Series B Preferred Stock converted into shares
        of Common Stock in accordance herewith, the Corporation shall deliver to
        the converting holder:

                (x) a certificate or certificates representing, in the
           aggregate, the number of shares of Common Stock issued upon such
           conversion in the same name or names as the certificates representing
           the converted shares (unless such holder shall have provided written
           notice to the Corporation to issue some or all of such converted
           shares in another name or names, in which case the Corporation shall
           deliver such certificates for such converted shares in such other
           name or names provided such holder delivers to the Corporation an
           opinion of counsel acceptable to the Corporation specifying that such
           issuance of converted shares to other parties is permissible under an
           available exemption from the registration requirements of the
           Securities Act of 1933, as amended, and the securities laws of any
           applicable state) and in such denomination or denominations as the
           converting holder shall specify and a check for cash with respect to
           any fractional interest in a share of Common Stock; and

                (y) with respect to an optional conversion pursuant to Section
           6(a) above, a certificate representing any shares of Series B
           Preferred Stock that were represented by the certificate or
           certificates delivered to the Corporation in connection with such
           conversion but that were not converted.

        From the Conversion Date and until such time as a holder of shares of
        Series B Preferred Stock shall surrender its certificate or certificates
        therefor as provided above, such certificates shall be deemed to
        represent the shares of Common Stock to which such holder shall be
        entitled upon the surrender thereof.

             (ii) Fully Paid Shares.  The issuance of certificates for shares of
        Common Stock upon conversion of Series B Preferred Stock shall be made
        without charge to the Holders of such Series B Preferred Stock for any
        issuance tax in respect thereof or other cost incurred by the
        Corporation in connection with such conversion and the related issuance
        of shares of Common Stock. Upon conversion of any shares of Series B
        Preferred Stock, the Corporation shall take all such actions as are
        necessary in order to insure that the Common Stock so issued upon such
        conversion shall be validly issued, fully paid and nonassessable.

             (iii) Timely Conversion.  The Corporation shall not close its books
        against the transfer of Series B Preferred Stock or of Common Stock
        issued or issuable upon conversion of Series B Preferred Stock in any
        manner that interferes with the timely conversion of Series B Preferred

                                       6

        Stock. The Corporation shall assist and cooperate with any holder of
        shares of Series B Preferred Stock required to make any governmental
        filings or obtain any governmental approval prior to or in connection
        with any conversion of shares of Series B Preferred Stock hereunder
        (including, without limitation, making any filings required to be made
        by the Corporation). The Corporation shall take all such actions as may
        be necessary to assure that all such shares of Common Stock may be so
        issued without violation of any applicable law or governmental
        regulation or any requirements of any domestic securities exchange upon
        which shares of Common Stock may be listed (except for official notice
        of issuance which shall be immediately delivered by the Corporation upon
        each such issuance).

             (iv) Reservation of Common Stock.  The Corporation shall at all
        times reserve and keep available out of its authorized but unissued
        shares of Common Stock, solely for the purpose of issuance upon the
        conversion of or otherwise pursuant to the terms of the Series B
        Preferred Stock, such number of shares of Common Stock as are issuable
        upon the conversion of or otherwise pursuant to the terms of all
        outstanding Series B Preferred Stock.

             (v) Fractional Shares.  No fractional shares of Common Stock or
        scrip shall be issued upon conversion of shares of the Series B
        Preferred Stock. If more than one share of Series B Preferred Stock
        shall be surrendered for conversion at any one time by the same Holder,
        the number of full shares of Common Stock issuable upon conversion
        thereof shall be computed on the basis of the aggregate number of shares
        of Series B Preferred Stock so surrendered. Instead of any fractional
        shares of Common Stock which would otherwise be issuable upon conversion
        of any shares of Series B Preferred Stock, the Corporation shall pay a
        cash adjustment in respect of such fractional interest equal to the fair
        market value of such fractional interest as determined by the
        Corporation's Board of Directors.

          (d) Conversion Price.  The initial conversion price shall be three and
     14/100 dollars ($3.14), which may be adjusted from time to time hereafter
     (as so adjusted, the "CONVERSION PRICE"). If and whenever on or after the
     original date of issuance of the Series B Preferred Stock the Corporation
     issues or sells, or in accordance with Section 6(e) below is deemed to have
     issued or sold, any shares of its Common Stock or Convertible Securities
     (other than Excluded Securities) for a consideration per share less than
     the Conversion Price in effect immediately prior to the time of such issue
     or sale, then upon such issue or sale, the Conversion Price in effect
     immediately prior to the time of such issue or sale shall be reduced to an
     amount equal to the consideration per share applicable to the Common Stock
     or Convertible Securities so issued or sold or deemed issued or sold in
     accordance with Section 6(e) below.

          (e) Effect on Conversion Price of Certain Events.  For purposes of
     determining the adjusted Conversion Price under Section 6(d), the following
     shall be applicable:

             (i) Issuance of Convertible Securities.  If the Corporation in any
        manner issues or sells any Convertible Securities, whether or not the
        rights to exercise, exchange or convert any such Convertible Securities
        are immediately exercisable, and the price per share for which Common
        Stock is issuable upon such exercise, conversion or exchange is less
        than the Conversion Price in effect immediately prior to the time of
        such issue or sale, then the maximum number of shares of Common Stock
        issuable upon exercise, conversion or exchange of such Convertible
        Securities shall be deemed to be outstanding and to have been issued and
        sold by the Corporation at the time of the issuance or sale of such
        Convertible Securities for such price per share. For the purposes of
        this paragraph, the "PRICE PER SHARE FOR WHICH COMMON STOCK IS ISSUABLE"
        shall be determined by dividing (x) the total amount received or
        receivable by the Corporation as consideration for the issue or sale of
        such Convertible Securities, plus the cumulative minimum aggregate
        amount of additional consideration, if any, payable to the Corporation
        upon the exercise, conversion or exchange thereof and, if applicable,
        the exercise, conversion and exchange of any other Convertible
        Securities that such Convertible Securities may be converted into or
        exchanged for, by (y) the total maximum number of shares of Common Stock
        issuable upon the exercise, conversion or exchange of all such
        Convertible Securities. No further adjustment of the Conversion Price
        shall be made when Common

                                       7
<PAGE>   39

        Stock and, if applicable, any other Convertible Securities, are actually
        issued upon the exercise, conversion or exchange of such Convertible
        Securities.

             (ii) Change in Exercise, Price or Conversion Rate.  If the
        additional consideration payable to the Corporation upon the exercise,
        conversion or exchange of any Convertible Securities, or the rate at
        which any Convertible Securities are convertible into or exercisable or
        exchangeable for Common Stock, changes at any time, the Conversion Price
        in effect at the time of such change shall be readjusted to the
        Conversion Price that would have been in effect at such time had such
        Convertible Securities that are still outstanding provided for such
        changed additional consideration or changed conversion rate, as the case
        may be, at the time such Convertible Securities were initially granted,
        issued or sold.

             (iii) Exceptions for Excluded Securities.  Notwithstanding the
        foregoing, no adjustments shall be made under this Section 6(e) with
        respect to the issuance of any Excluded Securities.

          (f) Subdivision or Combination of Common Stock.  If the Corporation at
     any time subdivides (by any stock split, stock dividend, recapitalization
     or otherwise) its outstanding shares of Common Stock into a greater number
     of shares, the Conversion Price in effect immediately prior to such
     subdivision shall be proportionately reduced, and conversely, in the event
     the outstanding shares of Common Stock shall be combined (by reverse stock
     split or otherwise) into a smaller number of shares, the Conversion Price
     in effect immediately prior to such combination shall be proportionately
     increased.

          (g) Certain Events.  If an event not specified in this Section 6
     occurs that has substantially the same economic effect on the Series B
     Preferred Stock as those specifically enumerated, then this Section 6 shall
     be construed liberally, mutatis mutandis, in order to give the Series B
     Preferred Stock the intended benefit of the protections provided under this
     Section 6. In such event, the Corporation's Board of Directors shall make
     an appropriate adjustment in the Conversion Price so as to protect the
     rights of the Holders.

          (h) Notices.

             (i) Immediately upon any adjustment of the Conversion Price, the
        Corporation shall give written notice thereof to all Holders, setting
        forth in reasonable detail and certifying the calculation of such
        adjustment and the facts upon which such adjustment is based.

             (ii) The Corporation shall give written notice to all Holders at
        least twenty (20) days prior to the date on which the Corporation closes
        its books or takes a record (x) with respect to any pro rata
        subscription offer to Holders of Common Stock, (y) with respect to any
        Liquidation Event or (z) with respect to any other right afforded to any
        holder of Common Stock.

          (i) Determination of Consideration.  For purposes of this Section 6,
     consideration received by the Corporation for the issue or sale of
     Convertible Securities in the form of property other than cash shall be
     computed at the fair value thereof at the time of such issue, as determined
     in good faith by the Board of Directors of the Corporation.

          7.  REDEMPTION.

          (a) Unless the following rights are waived or deferred in writing by
     the Majority Holders (including each Lead Investor), at any time after May
     31, 2006, any Holder may elect to have all shares of Series B Preferred
     Stock held by such Holder redeemed by the Corporation (an "OPTIONAL
     REDEMPTION"). In any such case, any Holder desiring to exercise its
     Optional Redemption right (a "REDEEMING HOLDER") shall notify the
     Corporation in writing of its intent to exercise the rights afforded by
     this Section 7(a) and specify a date not less than ten (10) nor more than
     sixty (60) days from the date of such notice on which all of such Holder's
     shares of Series B Preferred Stock shall be redeemed (an "OPTIONAL
     REDEMPTION DATE"). Within three (3) Trading Days after receipt by the
     Corporation of any such notice, the Corporation shall promptly notify each
     of the other Holders in writing of such Optional Redemption and provide a
     copy of the notice from such Redeeming Holder with such notice, whereupon
     each of the other Holders shall have an option for a period of fifteen (15)
     days to notify the Corporation in writing of its

                                       8
<PAGE>   40

     intent to exercise its Optional Redemption right on the Optional Redemption
     Date. On such Optional Redemption Date, the Corporation shall redeem all
     shares of Series B Preferred Stock held by such Redeeming Holder as well as
     all other Holders exercising such Optional Redemption right, as aforesaid,
     in cash by wire transfer of immediately available funds at a redemption
     price (the "REDEMPTION PRICE") equal to the sum of (i) the product of (x)
     the number of shares of Series B Preferred Stock held by such Redeeming
     Holder and each other Holder, respectively, and (y) the Purchase Price and
     (ii) all accrued but unpaid dividends thereon calculated to the Optional
     Redemption Date.

          (b) If the funds of the Corporation legally available for redemption
     of shares of Series B Preferred Stock on an Optional Redemption Date are
     insufficient to redeem the total number of shares of Series B Preferred
     Stock requested to be redeemed by Redeeming Holders on such Optional
     Redemption Date, the Redeeming Holders requesting redemption on such
     Optional Redemption Date shall share ratably in any funds legally available
     for redemption of such shares according to the respective amounts that
     would be payable with respect to the full number of shares owned by them if
     all such shares were redeemed in full. At any time, and from time to time,
     thereafter when additional funds of the Corporation are legally available
     for the redemption of such shares of Series B Preferred Stock, such funds
     will be used at the earliest permissible time to redeem the balance of such
     shares, or such portion thereof for which funds are then legally available.
     Such funds shall not be used by the Corporation for any other purpose,
     including the redemption by the Corporation of any shares of Convertible
     Securities which the Corporation is obligated to redeem on any subsequent
     date. The Corporation shall be obligated to use its reasonable efforts to
     take such actions as may be necessary in order to permit the full and
     timely redemption of the shares of Series B Preferred Stock entitled to
     redemption.

          (c) If, for any reason, the Corporation fails to redeem all shares of
     Series B Preferred Stock entitled to redemption on any Optional Redemption
     Date, the unredeemed shares shall remain outstanding and shall continue to
     have all rights and preferences (including, without limitation, dividend
     and voting rights) provided for herein and the Holders of such unredeemed
     shares shall have the ongoing right to be redeemed together with such
     rights and remedies as may be available under applicable law.

          (d) The notices provided for in this Section 7 shall be sent, (i) if
     by or on behalf of the Corporation, to the Holders at their respective
     addresses as shall then appear on the records of the Corporation by first
     class mail, postage prepaid, notifying such recipient of the redemption,
     the date of such redemption, the number of shares of Series B Preferred
     Stock to be redeemed, and the Redemption Price therefor and stating the
     place or places at which the shares that have been requested to be redeemed
     shall, upon presentation and surrender of such certificates representing
     such shares, be redeemed, and (ii) if by or on behalf of a Holder, to the
     Corporation at its executive office, currently located in Melbourne,
     Florida.

          (e) Any shares of Series B Preferred Stock redeemed pursuant to this
     Section 7 or otherwise acquired by the Corporation in any manner whatsoever
     shall be canceled and shall not under any circumstances be reissued; and
     the Corporation may from time to time take such appropriate corporate
     action as may be necessary to reduce accordingly the number of authorized
     shares of Series B Preferred Stock.

          8.  EXCLUSION OF OTHER RIGHTS.  Except as may otherwise be required by
     law, the shares of Series B Preferred Stock shall not have any preferences
     or relative, participating, optional or other special rights, other than
     those specifically set forth in this Certificate of Designation.

          9.  RANK.  The Series B Preferred Stock shall, with respect to
     redemption, dividend distributions and distributions upon liquidation,
     winding-up and dissolution of the Corporation, rank (i) senior to all
     classes of Common Stock of the Corporation, and to each other class of
     Capital Stock or series of Preferred Stock (including Series A Preferred
     Stock) now outstanding or hereafter created by the Board of Directors other
     than Parity Capital Stock or Senior Capital Stock (collectively referred to
     herein, together with all classes of Common Stock of the Corporation, as
     the "JUNIOR CAPITAL STOCK"), (ii) equally with any class of Capital Stock
     or series of Preferred Stock hereafter created by the Board of Directors
     and which expressly provide that such class or series will rank on a parity
     with the Series B Preferred Stock as to redemption, dividend distributions
     and distributions upon liquidation, winding-up

     and dissolution of the Corporation (collectively referred to as "PARITY
     CAPITAL STOCK"); and (iii) junior to each class of Capital Stock or series
     of Preferred Stock hereafter created by the Board of Directors the terms of
     which have been approved by the Majority Holders in accordance with Section
     5(a)(i) hereof and which expressly provide that such class or series will
     rank senior to the Series B Preferred Stock as to redemption, dividend
     distributions and distributions upon liquidation, winding-up and
     dissolution of the Corporation (collectively referred to as "SENIOR CAPITAL
     STOCK").

          10.  IDENTICAL RIGHTS.  Each share of the Series B Preferred Stock
     shall have the same relative rights and preferences as, and shall be
     identical in all respects with, all other shares of the Series B Preferred
     Stock.

          11.  CERTIFICATES.  So long as any shares of the Series B Preferred
     Stock are outstanding, there shall be set forth on the face or back of each
     stock certificate issued by the Corporation a statement that the
     Corporation shall furnish without charge to each shareholder who so
     requests, a full statement of the designation and relative rights,
     preferences and limitations of each class of stock or series thereof that
     the Corporation is authorized to issue and of the authority of the Board of
     Directors to designate and fix the relative rights, preferences and
     limitations of each series.

          12.  AMENDMENTS; WAIVERS.  Any provision of these terms of the Series
     B Preferred Stock may be amended, modified or waived if and only if the
     Majority Holders (including each Lead Investor) have consented in writing
     or by an affirmative vote to such amendment, modification or waiver of any
     such provision of this Certificate of Designation.

         3. Registration Procedures

            In connection with the Company's registration obligations hereunder,
the Company shall:

            (a) Prepare and file with the Commission on or prior to the Filing
Date, a Registration Statement on Form S-3 (or if the Company is not then
eligible to register for resale the Registrable Securities on Form S-3 such
registration shall be on another appropriate form in accordance herewith), and
cause the Registration Statement to become effective and remain effective as
provided herein; provided, however, that prior to the filing of the Registration
Statement or any related Prospectus or any amendment or supplement thereto
(including any document that would be incorporated or deemed to be incorporated
therein by reference), the Company shall, (i) furnish to the Holders and their
counsel, copies of all such documents proposed to be filed, which documents
(other than those incorporated or deemed to be incorporated by reference) will
be subject to the review of such Holders and their counsel, and (ii) cause its
officers and directors, counsel and independent certified public accountants to
respond to such inquiries as shall be necessary, in the reasonable opinion of
respective counsel to such Holders, to conduct a reasonable investigation within
the meaning of the Securities Act.

            (b) (i) Prepare and file with the Commission such amendments,
including post-effective amendments, to the Registration Statement as may be
necessary to keep the Registration Statement continuously effective as to the
applicable Registrable Securities for the Effectiveness Period and prepare and
file with the Commission such additional Registration Statements in order to
register for resale under the Securities Act all of the Registrable Securities;
(ii) cause the related Prospectus to be amended or supplemented by any required
Prospectus supplement, and as so supplemented or amended to be filed pursuant to
Rule 424 (or any similar provisions then in force) promulgated under the
Securities Act; (iii) respond as promptly as reasonably possible to any comments
received from the Commission with respect to the Registration Statement or any
amendment thereto and as promptly as reasonably possible provide the Holders
true and complete copies of all correspondence from and to the Commission
relating to the Registration Statement; and (iv) comply in all material respects
with the provisions of the Securities Act and the Exchange Act with respect to
the disposition of all Registrable Securities covered by the Registration
Statement during the applicable period in accordance with the intended methods
of disposition

                                      -4-
<PAGE>   49
by the Holders thereof set forth in the Registration Statement as so amended or
in such Prospectus as so supplemented.

            (c) Use its best efforts to avoid the issuance of, or, if issued,
obtain the withdrawal of (i) any order suspending the effectiveness of the
Registration Statement, or (ii) any suspension of the qualification (or
exemption from qualification) of any of the Registrable Securities for sale in
any jurisdiction, at the earliest practicable moment.

            (d) Furnish to each Holder and their counsel, without charge, at
least one conformed copy of each Registration Statement and each amendment
thereto, including financial statements and schedules, all documents
incorporated or deemed to be incorporated therein by reference, and all exhibits
to the extent requested by such Person (including those previously furnished or
incorporated by reference) after the filing of such documents with the
Commission.

            (e) Deliver to each Holder and their counsel, without charge, as
many copies of the Prospectus or Prospectuses (including each form of
prospectus) and each amendment or supplement thereto as such Persons may
reasonably request; and the Company hereby consents to the use of such
Prospectus and each amendment or supplement thereto by each of the selling
Holders in connection with the offering and sale of the Registrable Securities
covered by such Prospectus and any amendment or supplement thereto.

            (f) Prior to any public offering of Registrable Securities, use its
best efforts to register or qualify or cooperate with the selling Holders and
their counsel in connection with the registration or qualification (or exemption
from such registration or qualification) of such Registrable Securities for
offer and sale under the securities or Blue Sky laws of such jurisdictions
within the United States as any Holder requests in writing, to keep each such
registration or qualification (or exemption therefrom) effective during the
Effectiveness Period and to do any and all other acts or things necessary or
advisable to enable the disposition in such jurisdictions of the Registrable
Securities covered by a Registration Statement; provided, however, that the
Company shall not be required to qualify generally to do business in any
jurisdiction where it is not then so qualified or to take any action that would
subject it to general service of process in any such jurisdiction where it is
not then so subject or subject the Company to any material tax in any such
jurisdiction where it is not then so subject.

            (g) Cooperate with the Holders to facilitate the timely preparation
and delivery of certificates representing Registrable Securities to be delivered
to a transferee pursuant to a Registration Statement, which certificates shall
be free, to the extent permitted by applicable law, of all restrictive legends,
and to enable such Registrable Securities to be in such denominations and
registered in such names as any such Holders may request at least five Business
Days prior to any sale of Registrable Securities.

            (h) Use its best efforts to cause all Registrable Securities
relating to such Registration Statement to be listed on the Nasdaq National
Market ("NASDAQ") and any

                                      -5-
<PAGE>   50
other securities exchange, quotation system, market or over-the-counter bulletin
board, if any, on which similar securities issued by the Company are then listed
as and when required pursuant to the Purchase Agreement.

            (i) Make available for inspection by the selling Holders, any
representative of such Holders and any attorney or accountant retained by such
selling Holders at the offices where normally kept, during reasonable business
hours, all financial and other records, pertinent corporate documents and
properties of the Company and its subsidiaries, and cause the officers,
directors, agents and employees of the Company and its subsidiaries to supply
all information in each case reasonably requested by any such Holder,
representative, attorney or accountant in connection with the Registration
Statement; provided, however, that any information that is determined in good
faith by the Company to be of a confidential nature need not be disclosed in the
absence of a customary confidentiality agreement.

            (j) Comply with all applicable rules and regulations of the
Commission.

            (k) The Company may require each selling Holder to furnish to the
Company such information regarding the distribution of such Registrable
Securities and the beneficial ownership of Common Stock held by such Holder as
is required by law to be disclosed in the Registration Statement, and the
Company may exclude from such registration the Registrable Securities of any
such Holder who unreasonably fails to furnish such information within a
reasonable time after receiving such request.

            Each Holder covenants and agrees that (i) it will not sell any
Registrable Securities under the Registration Statement until it has received
copies of the Prospectus as then amended or supplemented as contemplated in
Section 3(e) and notice from the Company that such Registration Statement and
any post-effective amendments thereto have become effective and (ii) it and its
officers, directors or Affiliates, if any, will comply with the prospectus
delivery requirements of the Securities Act as applicable to it in connection
with sales of Registrable Securities pursuant to the Registration Statement.
Each Holder acknowledges that the Company is currently a party to agreements
pursuant to which the Company has granted "piggyback" registration rights to
other Persons and that such other Persons may exercise their right to include
Company securities they own in the Registration Statement.

            Each Holder agrees by its acquisition of such Registrable Securities
that, upon receipt of a notice from the Company (i) of any request by the
Commission or any other Federal or state governmental authority for amendments
or supplements to the Registration Statement or Prospectus or for additional
information; (ii) of the issuance by the Commission of any stop order suspending
the effectiveness of the Registration Statement covering any or all of the
Registrable Securities or the initiation of any Proceedings for that purpose;
(iii) if at any time any of the representations and warranties of the Company
contained in any agreement contemplated hereby ceases to be true and correct in
all material respects; (iv) of the receipt by the Company of any notification
with respect to the suspension of the qualification or

                                      -6-
<PAGE>   51
exemption from qualification of any of the Registrable Securities for sale in
any jurisdiction, or the initiation or threatening of any Proceeding for such
purpose; or (v) of the occurrence of any event that makes any statement made in
the Registration Statement or Prospectus or any document incorporated or deemed
to be incorporated therein by reference untrue in any material respect or that
requires any revisions to the Registration Statement, Prospectus or other
documents so that, in the case of the Registration Statement or the Prospectus,
as the case may be, it will not 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 they were
made, not misleading, such Holder will forthwith discontinue disposition of such
Registrable Securities under the Registration Statement until such Holder is
advised in writing (the "Advice") by the Company that the use of the applicable
Prospectus may be resumed, and has received copies of any additional or
supplemental filings that are incorporated or deemed to be incorporated by
reference in such Prospectus or Registration Statement.

         4. Registration Expenses

            All fees and expenses incident to the performance of or compliance
with this Agreement by the Company shall be borne by the Company whether or not
the Registration Statement is filed or becomes effective and whether or not any
Registrable Securities are sold pursuant to the Registration Statement. The fees
and expenses referred to in the foregoing sentence shall include, without
limitation, (i) all registration and filing fees (including, without limitation,

trading, and (B) in compliance with state securities or Blue Sky laws
(including, without limitation, fees and disbursements of counsel for the
Holders in connection with Blue Sky qualifications or exemptions of the

Securities for investment under the laws of such jurisdictions as the Holders of
a majority of Registrable Securities may designate)), (ii) printing expenses,
(iii) messenger, telephone and delivery expenses, (iv) fees and disbursements of
counsel for the Company and counsel for the Holders, (v) Securities Act

any annual audit, the fees and expenses incurred in connection with the listing
of the Registrable Securities on any securities exchange as required hereunder.

         5. Indemnification

            (a) Indemnification by the Company. The Company shall,
notwithstanding any termination of this Agreement, indemnify and hold harmless
each Holder, and the officers,

                                      -7-
<PAGE>   52
directors, agents and employees of each of them, each Person who controls any
such Holder (within the meaning of Section 15 of the Securities Act or Section
20 of the Exchange Act) and the officers, directors, agents and employees of
each such controlling Person, to the fullest extent permitted by applicable law,
from and against any and all losses, claims, damages, liabilities, costs
(including, without limitation, costs of preparation and attorneys' fees) and
expenses (collectively, "Losses"), as incurred, arising out of or relating to
any untrue or alleged untrue statement of a material fact contained in the
Registration Statement, any Prospectus or any form of prospectus or in any
amendment or supplement thereto or in any preliminary prospectus, or arising out
of or relating to any omission or alleged omission of a material fact required
to be stated therein or necessary to make the statements therein (in the case of
any Prospectus or form of prospectus or supplement thereto, in light of the
circumstances under which they were made) not misleading, except to the extent,
but only to the extent, that such untrue statements or omissions are based upon
information regarding such Holder furnished in writing to the Company by such
Holder expressly for use therein, which information was reasonably relied on by
the Company for use therein or to the extent that such information relates to
such Holder or such Holder's proposed method of distribution of Registrable
Securities. The Company shall notify the Holders of the institution, threat or
assertion of any Proceeding of which the Company is aware in connection with the
transactions contemplated by this Agreement.

            (b) Indemnification by Holders. Each Holder shall, severally and not
jointly, indemnify and hold harmless the Company and its directors, officers,
agents and employees, each Person who controls the Company (within the meaning
of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the
directors, officers, agents or employees of such controlling Persons, to the
fullest extent permitted by applicable law, from and against all Losses (as
determined by a court of competent jurisdiction in a final judgment not subject
to appeal or review) arising out of or based upon any untrue statement of a
material fact contained in the Registration Statement, any Prospectus, or any
form of prospectus, or in any amendment or supplement thereto, or arising out of
or based upon any omission of a material fact required to be stated therein or
necessary to make the statements therein not misleading to the extent, but only
to the extent, that such untrue statement or omission is contained in any
information so furnished in writing by such Holder to the Company for inclusion
in the Registration Statement or such Prospectus or to the extent that such
information relates to such Holder or such Holder's proposed method of
distribution of Registrable Securities.

            (c) Conduct of Indemnification Proceedings. If any Proceeding shall
be brought or asserted against any Person entitled to indemnity hereunder (an
"Indemnified Party"), such Indemnified Party shall promptly notify the Person
from whom indemnity is sought (the "Indemnifying Party") in writing, and the
Indemnifying Party shall assume the defense thereof, including the employment of
counsel reasonably satisfactory to the Indemnified Party and the payment of all
fees and expenses incurred in connection with defense thereof; provided, that
the failure of any Indemnified Party to give such notice shall not relieve the
Indemnifying Party of its obligations or liabilities pursuant to this Agreement,
except (and only) to the extent that it shall be finally determined by a court
of competent

                                      -8-
<PAGE>   53
jurisdiction (which determination is not subject to appeal or further review)
that such failure shall have proximately and materially adversely prejudiced the
Indemnifying Party.

            An Indemnified Party shall have the right to employ separate counsel
in any such Proceeding and to participate in the defense thereof, but the fees
and expenses of such counsel shall be at the expense of such Indemnified Party
or Parties unless: (1) the Indemnifying Party has agreed in writing to pay such
fees and expenses; or (2) the Indemnifying Party shall have failed promptly to
assume the defense of such Proceeding and to employ counsel reasonably
satisfactory to such Indemnified Party in any such Proceeding; or (3) the named
parties to any such Proceeding (including any impleaded parties) include both
such Indemnified Party and the Indemnifying Party, and such Indemnified Party
shall have been advised by counsel that a conflict of interest is likely to
exist if the same counsel were to represent such Indemnified Party and the
Indemnifying Party (in which case, if such Indemnified Party notifies the
Indemnifying Party in writing that it elects to employ separate counsel at the
expense of the Indemnifying Party, the Indemnifying Party shall not have the
right to assume the defense thereof and such counsel shall be at the expense of
the Indemnifying Party). The Indemnifying Party shall not be liable for any
settlement of any such Proceeding effected without its written consent, which
consent shall not be unreasonably withheld. No Indemnifying Party shall, without
the prior written consent of the Indemnified Party, effect any settlement of any
pending Proceeding in respect of which any Indemnified Party is a party, unless
such settlement includes an unconditional release of such Indemnified Party from
all liability on claims that are the subject matter of such Proceeding.

            All fees and expenses of the Indemnified Party (including reasonable
fees and expenses to the extent incurred in connection with investigating or
preparing to defend such Proceeding in a manner not inconsistent with this
Section) shall be paid to the Indemnified Party, as incurred, within thirty (30)
Business Days of written notice thereof to the Indemnifying Party (regardless of
whether it is ultimately determined that an Indemnified Party is not entitled to
indemnification hereunder; provided, that the Indemnifying Party may require
such Indemnified Party to undertake to reimburse all such fees and expenses to
the extent it is finally judicially determined that such Indemnified Party is
not entitled to indemnification hereunder).

            (d) Contribution. If a claim for indemnification under Section 5(a)
or 5(b) is unavailable to an Indemnified Party (by reason of public policy or
otherwise), then each Indemnifying Party, in lieu of indemnifying such
Indemnified Party, shall contribute to the amount paid or payable by such
Indemnified Party as a result of such Losses, in such proportion as is
appropriate to reflect the relative fault of the Indemnifying Party and
Indemnified Party in connection with the actions, statements or omissions that
resulted in such Losses as well as any other relevant equitable considerations.
The relative fault of such Indemnifying Party and Indemnified Party shall be
determined by reference to, among other things, whether any action in question,
including any untrue or alleged untrue statement of a material fact or omission
or alleged omission of a material fact, has been taken or made by, or relates to
information supplied by, such Indemnifying Party or Indemnified Party, and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent

                                      -9-
<PAGE>   54
such action, statement or omission. The amount paid or payable by a party as a
result of any Losses shall be deemed to include, subject to the limitations set
forth in Section 5(c), any reasonable attorneys' or other reasonable fees or
expenses incurred by such party in connection with any Proceeding to the extent
such party would have been indemnified for such fees or expenses if the
indemnification provided for in this Section was available to such party in
accordance with its terms.

            The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 5(d) were determined by pro rata
allocation or by any other method of allocation that does not take into account
the equitable considerations referred to in the immediately preceding paragraph.
Notwithstanding the provisions of this Section 5(d), no Holder shall be required
to contribute, in the aggregate, any amount in excess of the amount by which the
proceeds actually received by such Holder from the sale of the Registrable
Securities subject to the Proceeding exceeds the amount of any damages that such
Holder has otherwise been required to pay by reason of such untrue or alleged
untrue statement or omission or alleged omission. No Person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any Person who was not guilty of such
fraudulent misrepresentation.

            The indemnity and contribution agreements contained in this Section
are in addition to any liability that the Indemnifying Parties may have to the
Indemnified Parties.

         6. Miscellaneous

            (a) Remedies. In the event of a breach by the Company or by a
Holder, of any of their obligations under this Agreement, each Holder or the
Company, as the case may be, in addition to being entitled to exercise all
rights granted by law and under this Agreement, including recovery of damages,
will be entitled to specific performance of its rights under this Agreement. The
Company and each Holder agree that monetary damages would not provide adequate
compensation for any losses incurred by reason of a breach by it of any of the
provisions of this Agreement and hereby further agrees that, in the event of any
action for specific performance in respect of such breach, it shall waive the
defense that a remedy at law would be adequate.

            (b) No Inconsistent Agreements. Neither the Company nor any of its
subsidiaries shall, on or after the date of this Agreement, enter into any
agreement with respect to its securities that is inconsistent with the rights
granted to the Holders in this Agreement or otherwise conflicts with the
provisions hereof.

            (c) Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, unless the same shall be in writing and signed by the Company and
the Holders of at least two-thirds of the then outstanding Registrable

                        AIRNET COMMUNICATIONS CORPORATION

                          Common Stock Purchase Warrant

         AIRNET COMMUNICATIONS CORPORATION, a Delaware corporation (the
"Company", hereby certifies that, for value received,
__________________________________, or its assigns (the "Purchaser"), is
entitled, subject to the terms and conditions set forth below, to purchase from
the Company that number of fully paid and non-assessable shares of Common Stock,
par value $.001 per share, of the Company ("Common Stock"), determined as set
forth in Section 1.1, at the purchase price per share of Three and 14/100
Dollars ($3.14) (the "Warrant Price"), at any time or from time to time after
the date hereof (the "Issue Date") and before 5:00 p.m., Eastern Time, on the
Expiration Date (as defined in Section 1.5).

         This Common Stock Purchase Warrant ("Warrant") is granted in connection
with transactions contemplated by the Securities Purchase Agreement, dated April
2, 2001, among the Company, SCP and certain other parties (the "Stock Purchase
Agreement") entered into in connection with the Company's offering of Series B
Convertible Preferred Stock and warrants (the "Offering"). Unless the context
shall otherwise require, capitalized terms used herein shall have the meanings
assigned to them in the Stock Purchase Agreement, which also contains rules of
construction applicable to this Warrant.

         1. Exercise of Warrant.

         1.1 Number of Shares for Which Warrant is Exercisable. This Warrant
shall be exercisable for [30% OF THE NUMBER OF SHARES OF COMMON STOCK INTO WHICH

                                      -1-
<PAGE>   60

         1.2 Manner of Exercise. The holder hereof may exercise this Warrant, in
whole or in part in the following manner:

                  (a) Cash Exercise. At anytime, by surrender of this Warrant to
         the Company on any Business Day at its principal office, which is
         currently located in Melbourne, Florida, accompanied by a statement in
         the form of the subscription at the end hereof (or a reasonable
         facsimile thereof), duly executed by such holder, and by consideration
         in the amount obtained by multiplying (a) the number of shares of
         Common Stock designated in such statement by (b) the Warrant Price, and
         such holder shall thereupon be entitled to receive the number of fully
         paid and non-assessable shares of Common Stock designated in such
         statement. The consideration for the exercise of this Warrant shall be
         (i) in the form of cash or a bank cashier's or certified check payable
         to the order of the Company or (ii) by wire transfer to an account
         designated in writing by the Company.

                  (b) Cashless Exercise. Notwithstanding anything to the
         contrary contained in this Warrant, this Warrant may be exercised at
         any time during the Exercise Period (as defined below) by presentation
         and surrender of this Warrant to the Company on any Business Day at its
         principal office, which is currently located in Melbourne, Florida,
         accompanied by a statement in the form attached hereto (or a reasonable
         facsimile thereof), duly executed by such holder indicating such
         holder's intention to effect a cashless exercise, including a
         calculation of the number of shares of Common Stock to be issued upon
         such exercise in accordance with the terms hereof (a "Cashless
         Exercise"). In the event of a Cashless Exercise, in lieu of paying the
         Warrant Price in cash, the holder shall surrender this Warrant for that
         number of shares of Common Stock determined by multiplying the number
         of shares of Common Stock issuable upon exercise of this Warrant to
         which it would otherwise be entitled by a fraction, the numerator of
         which shall be the difference between the then current Market Price of
         a share of the Common Stock on the date of exercise and the Warrant
         Price, and the denominator of which shall be the then current Market
         Price per share of Common Stock. For purposes of this Warrant, the term
         "Market Price" means the average of the closing bid prices for the
         shares of Common Stock as reported on the Nasdaq National Market by
         Bloomberg Financial Markets ("Bloomberg") for the five consecutive
         trading days immediately preceding such date, or (ii) if the Nasdaq
         National Market is not the principal trading market for the shares of
         Common Stock, the average of the reported bid prices reported by
         Bloomberg on the principal trading market for the Common Stock during
         the same period, or, if there is no bid price for such period, the last
         sales price reported by Bloomberg for such period, or (iii) if the
         foregoing do not apply, the last sale price of such security in the
         over-the-counter market on the pink sheets or bulletin board for such
         security as reported by Bloomberg, or if no sale price is so reported
         for such security, the last bid price of such security as reported by
         Bloomberg, or (iv) if market value cannot be calculated as of such date
         on any of the foregoing bases, the Market Price shall be the average
         fair market value as reasonably determined by an investment banking
         firm selected by the Company and reasonably

                                      -2-
<PAGE>   61
         acceptable to the holder, with the costs of the appraisal to be borne
         by the Company. The manner of determining the Market Price of the
         Common Stock set forth in the foregoing definition shall apply with
         respect to any other security in respect of which a determination as to
         market value must be made hereunder.

         1.3 When Exercise Effective. Each exercise of this Warrant shall be
deemed to have been effective immediately prior to the close of business on the
business day on which this Warrant is surrendered to the Company as provided in
Section 1.2, and at such time the person or persons in whose name or names any
certificate or certificates for shares of Common Stock shall be issuable upon
such exercise as provided in Section 1.4 shall be deemed to have become the
holder or holders of record thereof.

         1.4 Delivery of Stock Certificates, Etc. As soon as practicable after
the exercise of this Warrant in whole or in part, and in any event within 10
days thereafter, the Company at its expense (including the payment by it of any
applicable issue taxes) will cause to be issued in the name of and delivered to
the holder hereof or as such holder (upon payment by such holder of any
applicable transfer taxes) may direct:

                  (a) a certificate or certificates for the number of validly
         issued, fully paid and non-assessable shares of Common Stock to which
         such holder shall be entitled upon such exercise, which shares shall be
         free and clear of all taxes, liens, claims, preemptive or similar
         rights, and encumbrances, and

                  (b) in case such exercise is in part only, a new Warrant or
         Warrants of like tenor, calling in the aggregate on the face or faces
         thereof for the number of shares of Common Stock equal to the number of
         such shares called for on the face of this Warrant minus the number of
         such shares designated by the holder upon such exercise as provided in
         Section 1.2.

         1.5 Expiration. This Warrant shall expire on              , 2011 (said
date is referred to herein as the "Expiration Date" and the period of time
between the Issue Date and the Expiration Date is referred to herein as the
"Exercise Period").

         2. Adjustments for Consolidation, Merger, Sale of Assets,
Reorganization, Etc. In case the Company, (a) shall consolidate with or merge
into any person and shall not be the continuing or surviving corporation of such
consolidation or merger, or (b) shall permit any other person to consolidate
with or merge into the Company and the Company shall be the continuing or
surviving person, but, in connection with such consolidation or merger, the
Common Stock shall be changed into or exchanged for stock or other securities or
property of any other person, or (c) shall transfer all or substantially all of
its properties and assets to any other person, then, and in each such case,
proper provision shall be made so that the holder of this Warrant, upon the
exercise of this Warrant at any time after the consummation of such
consolidation, merger, transfer, reorganization or reclassification, shall be
entitled to receive, in lieu of the Common Stock issuable upon such exercise
prior to such consummation, the stock and other securities and property that
such holder would have been entitled to upon such exercise if such holder had so
exercised this Warrant immediately prior thereto.

                                      -3-
<PAGE>   62
         3. Antidilution Provisions. Prior to the Expiration Date, the Warrant
Price and the number of shares of Common Stock purchaseable hereunder ("Warrant
Shares") shall be subject to adjustment from time to time as provided in this
Section 3.

         (a) Adjustment of Warrant Price and Number of Shares upon Issuance of
Common Stock. Except as otherwise provided in Sections 3(b)(iv), 3(c) and 3(e)
hereof, if and whenever during the Exercise Period, after the Issue Date, the
Company issues or sells, or in accordance with Section 3(b) hereof is deemed to
have issued or sold, any shares of Common Stock for no consideration or for a
consideration per share less than the Warrant Price in effect immediately prior
to the issuance of such shares (other than any issuance pursuant to the Stock
Purchase Agreement and shares of Series B Convertible Preferred Stock issued as
dividends on the Company's Series B Convertible Preferred Stock (a "Dilutive
Issuance"), then effective immediately upon the Dilutive Issuance, the Warrant
Price in effect immediately prior to each such issuance shall forthwith be
reduced to the lowest price per share paid for such Common Stock (or deemed paid
for such Common Stock pursuant to Section 3(b)(v) below).

         (b) Effect on Warrant Price of Certain Events. For purposes of
determining the adjusted Warrant Price under Section 3(a) hereof, the following
will be applicable:

            (i) Issuance of Rights or Options. If the Company in any manner
issues or grants any warrants, rights or options, whether or not immediately
exercisable, to subscribe for or to purchase Common Stock or other securities
exercisable, convertible into or exchangeable for Common Stock ("Convertible
Securities") (such warrants, rights and options to purchase Common Stock or
Convertible Securities are hereinafter referred to as "Options") and the price
per share for which Common Stock is issuable upon the exercise of such Options
is less than the Warrant Price in effect on the date of issuance of such Options
("Discounted Options"), then the maximum total number of shares of Common Stock
issuable upon the exercise of all such Discounted Options (assuming full
exercise, conversion or exchange of Convertible Securities, if applicable) will,
as of the date of the issuance or grant of such Discounted Options, be deemed to
be outstanding and to have been issued and sold by the Company for such price
per share. For purposes of the preceding sentence, the "price per share for
which Common Stock is issuable upon the exercise of such Discounted Options" is
determined by dividing (i) the total amount, if any, received or receivable by
the Company as consideration for the issuance or granting of all such Discounted
Options, plus the minimum aggregate amount of additional consideration, if any,
payable to the Company upon the exercise of all such Discounted Options, plus,
in the case of Convertible Securities issuable upon the exercise of such
Discounted Options, the minimum aggregate amount of additional consideration
payable upon the exercise, conversion or exchange thereof at the time such
Convertible Securities first become exercisable, convertible or exchangeable, by
(ii) the maximum total number of shares of Common Stock issuable upon the
exercise of all such Discounted Options (assuming full conversion of Convertible
Securities, if applicable). No further adjustment to the Warrant Price will be
made upon the actual issuance of such Common Stock upon the exercise of such
Discounted Options or upon the exercise, conversion or exchange of Convertible
Securities issuable upon exercise of such Discounted Options.

                                      -4-

            (ii) Issuance of Convertible Securities.

               (A) If the Company in any manner issues or sells any Convertible
Securities, whether or not immediately convertible (other than where the same
are issuable upon the exercise of Options) and the price per share for which
Common Stock is issuable upon such exercise, conversion or exchange (as
determined pursuant to Section 3(b)(ii)(B) if applicable) is less than the
Warrant Price in effect on the date of issuance of such Convertible Securities,
then the maximum total number of shares of Common Stock issuable upon the
exercise, conversion or exchange of all such Convertible Securities will, as of
the date of the issuance of such Convertible Securities, be deemed to be
outstanding and to have been issued and sold by the Company for such price per
share. For the purposes of the preceding sentence, the "price per share for
which Common Stock is issuable upon such exercise, conversion or exchange" is
determined by dividing (i) the total amount, if any, received or receivable by
the Company as consideration for the issuance or sale of all such Convertible
Securities, plus the minimum aggregate amount of additional consideration, if
any, payable to the Company upon the exercise, conversion or exchange thereof at
the time such Convertible Securities first become exercisable, convertible or
exchangeable, by (ii) the maximum total number of shares of Common Stock
issuable upon the exercise, conversion or exchange of all such Convertible
Securities. No further adjustment to the Warrant Price will be made upon the
actual issuance of such Common Stock upon exercise, conversion or exchange of
such Convertible Securities.

               (B) If the Company in any manner issues or sells any Convertible
Securities with a fluctuating conversion or Warrant Price or exchange ratio (a
"Variable Rate Convertible Security"), then the "price per share for which
Common Stock is issuable upon such exercise, conversion or exchange" for
purposes of the calculation contemplated by Section 3(b)(ii)(A) shall be deemed
to be the lowest price per share which would be applicable (assuming all holding
period and other conditions to any discounts contained in such Convertible
Security have been satisfied) if the Market Price in effect on the date of
issuance of such Convertible Security was 75% of the Market Price in effect on
such date (the "Assumed Variable Market Price"). Further, if the Market Price in
effect at any time or times thereafter is less than or equal to the Assumed
Variable Market Price last used for making any adjustment under this Section 3
with respect to any Variable Rate Convertible Security, the Warrant Price in
effect at such time shall be readjusted to equal the Warrant Price which would
have resulted if the Assumed Variable Market Price in effect at the time of
issuance of the Variable Rate Convertible Security had been 75% of the Market
Price in effect at the time of the adjustment required by this sentence.

            (iii) Change in Option Price or Conversion Rate. If there is a
change at any time in (i) the amount of additional consideration payable to the
Company upon the exercise of any Options; (ii) the amount of additional
consideration, if any, payable to the Company upon the exercise, conversion or
exchange of any Convertible Securities; or (iii) the rate at which any
Convertible Securities are convertible into or exchangeable for Common Stock (in
each such case, other than under or by reason of provisions designed to protect
against dilution and except when an adjustment is made pursuant to Section
3(b)(ii)(B) hereof), the Warrant Price in effect at the time of such change will
be readjusted to the Warrant Price which would have been in effect

                                      -5-
<PAGE>   64
at such time had such Options or Convertible Securities still outstanding
provided for such changed additional consideration or changed conversion rate,
as the case may be, at the time initially granted, issued or sold.

            (iv) Treatment of Expired Options and Unexercised Convertible
Securities. If, in any case, the total number of shares of Common Stock issuable
upon exercise of any Option or upon exercise, conversion or exchange of any
Convertible Securities is not, in fact, issued and the rights to exercise such
Option or to exercise, convert or exchange such Convertible Securities shall
have expired or terminated, the Warrant Price then in effect will be readjusted
to the Warrant Price which would have been in effect at the time of such
expiration or termination had such Option or Convertible Securities, to the
extent outstanding immediately prior to such expiration or termination (other
than in respect of the actual number of shares of Common Stock issued upon
exercise or conversion thereof), never been issued.

            (v) Calculation of Consideration Received. If any Common Stock,
Options or Convertible Securities are issued, granted or sold for cash, the
consideration received therefor for purposes of this Warrant will be the amount
received by the Company therefor, before deduction of reasonable commissions,
underwriting discounts or allowances or other reasonable expenses paid or
incurred by the Company in connection with such issuance, grant or sale. In case
any Common Stock, Options or Convertible Securities are issued or sold for a
consideration part or all of which shall be other than cash, the amount of the
consideration other than cash received by the Company will be the fair market
value of such consideration, except where such consideration consists of
securities, in which case the amount of consideration received by the Company
will be the Market Price thereof as of the date of receipt. In case any Common
Stock, Options or Convertible Securities are issued in connection with any
merger or consolidation in which the Company is the surviving corporation, the
amount of consideration therefor will be deemed to be the fair market value of
such portion of the net assets and business of the non-surviving corporation as
is attributable to such Common Stock, Options or Convertible Securities, as the
case may be. The fair market value of any consideration other than cash or
securities will be determined in good faith by an investment banker or other
appropriate expert of national reputation selected by the Company and reasonably
acceptable to the holder hereof, with the costs of such appraisal to be borne by
the Company.

            (vi) Exceptions to Adjustment of Warrant Price. No adjustment to the
Warrant Price will be made (i) upon the exercise or conversion of any warrants,
options, subscriptions, convertible notes, convertible debentures, convertible
preferred stock or other convertible securities issued and outstanding at
Closing (as defined in the Stock Purchase Agreement) in accordance with the
terms of such securities as of such date; (ii) upon the grant or exercise of any
stock or options which may hereafter be granted or exercised under any employee
benefit plan of the Company now existing or to be implemented in the future, or
upon grant or exercise of any stock or options to or by any officer, director or
employee of the Company, whether or not under a plan, so long as the issuance of
such stock or options is approved by a majority of the non-employee members of
the Board of Directors of the Company or a majority of the members of a
committee of non-employee directors established for such purpose; (iii) upon the
issuance of any Warrants issued or issuable in accordance with the terms of the
Stock Purchase Agreement; (iv) upon exercise of the Warrants; (v) upon the
issuance of securities in

                                      -6-
<PAGE>   65
connection with an underwritten public offering of the Company; and (vi) upon
the issuance of securities issued as the result of anti-dilution rights granted
to a third party, which securities are outstanding as of the date hereof.

            (c) Subdivision or Combination of Common Stock. If the Company, at
any time during the Exercise Period subdivides (by any stock split, stock
dividend, recapitalization, reorganization, reclassification or otherwise) its
shares of Common Stock into a greater number of shares, then, after the date of
record for effecting such subdivision, the Warrant Price in effect immediately
prior to such subdivision will be proportionately reduced. If the Company, at
any time during the Exercise Period, combines (by reverse stock split,
recapitalization, reorganization, reclassification or otherwise) its shares of
Common Stock into a smaller number of shares, then, after the date of record for
effecting such combination, the Warrant Price in effect immediately prior to
such combination will be proportionately increased.

            (d) Adjustment in Number of Shares. Upon each adjustment of the
Warrant Price pursuant to the provisions of this Section 3, the number of shares
of Common Stock issuable upon exercise of this Warrant and for which this
Warrant is or may become exercisable shall be adjusted by multiplying a number
equal to the Warrant Price in effect immediately prior to such adjustment by the
number of shares of Common Stock issuable upon exercise of this Warrant and for
which this Warrant is or may become exercisable immediately prior to such
adjustment and dividing the product so obtained by the adjusted Warrant Price.

            (e) Consolidation or Merger. In case of any consolidation of the
Company with, or merger of the Company into, any other corporation, or in case
of any sale or conveyance of all or substantially all of the assets of the
Company at any time during the Exercise Period, then as a condition of such
consolidation, merger or sale or conveyance, adequate provision will be made
whereby the holder of this Warrant will have the right to acquire and receive
upon exercise of this Warrant in lieu of the shares of Common Stock immediately
theretofore acquirable upon the exercise of this Warrant, such shares of stock,
securities, cash or assets as may be issued or payable with respect to or in
exchange for the number of shares of Common Stock immediately theretofore
acquirable and receivable upon exercise of this Warrant had such consolidation,
merger, sale or conveyance not taken place. In any such case, the Company will
make appropriate provision to insure that the provisions of this Section 3
hereof will thereafter be applicable as nearly as may be in relation to any
shares of stock or securities thereafter deliverable upon the exercise of this
Warrant. The Company will not effect any consolidation, merger, sale or
conveyance unless prior to the consummation thereof, the successor corporation
(if other than the Company) assumes by written instrument the obligations under
this Warrant and the obligations to deliver to the holder of this Warrant such
shares of stock, securities or assets as, in accordance with the foregoing
provisions, the holder may be entitled to acquire. Notwithstanding the
foregoing, in the event of any consolidation of the Company with, or merger of
the Company into, any other corporation, or the sale or conveyance of all or
substantially all of the assets of the Company, at any time during the Exercise
Period, the holder of the Warrant shall, at its option, have the right to
receive, in connection with such transaction, cash consideration equal to the
fair market value of this Warrant as determined in accordance with customary
valuation methodology used in the investment banking industry.

<PAGE>   66
            (f) Distribution of Assets. In case the Company shall declare or
make any distribution of its assets (or rights to acquire its assets) to holders
of Common Stock as a dividend, by way of return of capital or otherwise
(including any dividend or distribution to the Company's stockholders of cash or
shares (or rights to acquire shares) of capital stock of a subsidiary) (a
"Distribution"), at any time during the Exercise Period, then the holder of this
Warrant shall be entitled upon exercise of this Warrant for the purchase of any
or all of the shares of Common Stock subject hereto, to receive the amount of
such assets (or rights) which would have been payable to the holder had such
holder been the holder of such shares of Common Stock on the record date for the
determination of shareholders entitled to such Distribution.

            (g) Notice of Adjustment. Upon the occurrence of any event which
requires any adjustment of the Warrant Price, then, and in each such case, the
Company shall give notice thereof to the holder of this Warrant, which notice
shall state the Warrant Price resulting from such adjustment and the increase or
decrease in the number of Warrant Shares purchasable at such price upon
exercise, setting forth in reasonable detail the method of calculation and the
facts upon which such calculation is based. Such calculation shall be certified
by the chief financial officer of the Company.

            (h) Minimum Adjustment of Warrant Price. No adjustment of the
Warrant Price shall be made in an amount of less than 1% of the Warrant Price in
effect at the time such adjustment is otherwise required to be made, but any
such lesser adjustment shall be carried forward and shall be made at the time
and together with the next subsequent adjustment which, together with any
adjustments so carried forward, shall amount to not less than 1% of such Warrant
Price.

            (i) No Fractional Shares. No fractional shares of Common Stock are
to be issued upon the exercise of this Warrant, but the Company shall pay a cash
adjustment in respect of any fractional share which would otherwise be issuable
in an amount equal to the same fraction of the Market Price of a share of Common
Stock on the date of such exercise.

            (j) Other Notices. In case at any time:

               (i) the Company shall declare any dividend upon the Common Stock
payable in shares of stock of any class or make any other distribution (other
than dividends or distributions payable in cash out of retained earnings
consistent with the Company's past practices with respect to declaring dividends
and making distributions) to the holders of the Common Stock;

               (ii) the Company shall offer for subscription pro rata to the
holders of the Common Stock any additional shares of stock of any class or other
rights;

               (iii) there shall be any capital reorganization of the Company,
or reclassification of the Common Stock, or consolidation or merger of the
Company with or into, or sale of all or substantially all of its assets to,
another corporation or entity; or

                                      -8-
<PAGE>   67
               (iv) there shall be a voluntary or involuntary dissolution,
liquidation or winding-up of the Company; then, in each such case, the Company
shall give to the holder of this Warrant (a) notice of the date on which the
books of the Company shall close or a record shall be taken for determining the
holders of Common Stock entitled to receive any such dividend, distribution, or
subscription rights or for determining the holders of Common Stock entitled to
vote in respect of any such reorganization, reclassification, consolidation,
merger, sale, dissolution, liquidation or winding-up and (b) in the case of any
such reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation or winding up, notice of the date (or, if not then known, a
reasonable estimate thereof by the Company) when the same shall take place. Such
notice shall also specify the date on which the holders of Common Stock shall be
entitled to receive such dividend, distribution, or subscription rights or to
exchange their Common Stock for stock or other securities or property
deliverable upon such reorganization, reclassification, consolidation, merger,
sale, dissolution, liquidation, or winding-up, as the case may be. Such notice
shall be given at least thirty (30) days prior to the record date or the date on
which the Company's books are closed in respect thereto. Failure to give any
such notice or any defect therein shall not affect the validity of the
proceedings referred to in clauses (i), (ii), (iii) and (iv) above.
Notwithstanding the foregoing, the Company shall publicly disclose the substance
of any notice delivered hereunder prior to delivery of such notice to the holder
of this Warrant.

            (k) Certain Events. If, at any time after the Issue Date, any event
occurs of the type contemplated by the adjustment provisions of this Section 3
but not expressly provided for by such provisions, the Company will give notice
of such event as provided in Section 3(g) hereof, and the Company's Board of
Directors will make an appropriate adjustment in the Warrant Price and the
number of shares of Common Stock acquirable upon exercise of this Warrant so
that the rights of the holder shall be neither enhanced nor diminished by such
event.

            (l) Certain Definitions.

               (i) "Common Stock Deemed Outstanding" shall mean the number of
shares of Common Stock actually outstanding (not including shares of Common
Stock held in the treasury of the Company), plus (x) in the case of any
adjustment required by Section 3(a) resulting from the issuance of any Options,
the maximum total number of shares of Common Stock issuable upon the exercise of
the Options for which the adjustment is required (including any Common Stock
issuable upon the conversion of Convertible Securities issuable upon the
exercise of such Options), and (y) in the case of any adjustment required by
Section 3(a) resulting from the issuance of any Convertible Securities, the
maximum total number of shares of Common Stock issuable upon the exercise,
conversion or exchange of the Convertible Securities for which the adjustment is
required, as of the date of issuance of such Convertible Securities, if any.
Except as specifically provided by the foregoing, no other derivative securities
(and underlying shares) shall be deemed outstanding for purposes of this
definition.

               (ii) "Common Stock," for purposes of this Section 3, includes the
Common Stock and any additional class of stock of the Company having no
preference as to dividends or distributions on liquidation, provided that the
shares purchasable pursuant to this Warrant shall include only Common Stock in
respect of which this Warrant is exercisable, or

                                      -9-
<PAGE>   68
shares resulting from any subdivision or combination of such Common Stock, or in
the case of any reorganization, reclassification, consolidation, merger, or sale
of the character referred to in Section 3(e) hereof, the stock or other
securities or property provided for in such Section.

         4. Covenants of the Company; No Dilution or Impairment. Until the
Expiration Date, or the exercise of this Warrant in full, the Company shall not,
by amendment of its certificate of incorporation or through any reorganization,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities, or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms of this Warrant, but shall at all times in
good faith assist in the carrying out of all such terms and in the taking of all
such action as may be necessary or appropriate in order to protect the rights of
the holder of this Warrant against dilution or other impairment. Without
limiting the generality of the foregoing, the Company:

                  (a) shall take all such action as may be necessary or
         appropriate in order that the Company may validly and legally issue
         fully paid and non-assessable shares of Common Stock upon the exercise
         of this Warrant; and

                  (b) shall not (i) transfer all or substantially all of its
         properties and/or assets to any other person, or (ii) consolidate with
         or merge into any other person where the Company is not the continuing
         or surviving person, or (iii) permit any other person to consolidate
         with or merge into the Company where the Company is the continuing or
         surviving person but, in connection with such consolidation or merger,
         the Common Stock then issuable upon the exercise of this Warrant shall
         be changed into or exchanged for stock or other securities or property
         of any other person unless, in any such case, the other person
         acquiring such properties and assets, continuing or surviving after
         such consolidation or merger or issuing or distributing such stock or
         other securities or property, as the case may be, shall expressly
         assume in writing and be bound by all the terms of this Warrant.

                  (c) shall promptly secure the listing of the shares of Common
         Stock issuable upon exercise of this Warrant upon each national
         securities exchange or automated quotation system, if any, upon which
         shares of Common Stock are then listed or become listed (subject to
         official notice of issuance upon exercise of this Warrant) and shall
         maintain, so long as any other shares of Common Stock shall be so
         listed, such listing of all shares of Common Stock from time to time
         issuable upon the exercise of this Warrant; and the Company shall so
         list on each national securities exchange or automated quotation
         system, as the case may be, and shall maintain such listing of, any
         other shares of capital stock of the Company issuable upon the exercise
         of this Warrant if and so long as any shares of the same class shall be
         listed on such national securities exchange or automated quotation
         system; and

                  (d) shall, on or before the date of issuance of any shares of
         Common Stock issuable upon exercise of this Warrant, take such actions
         as the Company shall reasonably determine are necessary to qualify such
         shares of Common Stock for, or obtain exemption for such shares of
         Common Stock for, sale to the holder

                                      -10-
<PAGE>   69
         of this Warrant upon the exercise hereof under applicable securities or
         "blue sky" laws of the states of the United States, and shall provide
         evidence of any such action so taken to the holder of this Warrant
         prior to such date; provided, however, that the Company shall not be
         required in connection therewith or as a condition thereto to (i)
         qualify to do business in any jurisdiction where it would not otherwise
         be required to qualify but for this subsection, (ii) subject itself to
         general taxation in any such jurisdiction or (iii) file a general
         consent to service of process in any such jurisdiction.

5.       Notices of Record Date, Etc. If the Company proposes:

                  (a) to take a record of the holders of any class of securities
         for the purpose of determining holders thereof who are entitled to vote
         at any meeting of stockholders for any purpose (or to take action by
         written consent in lieu of a meeting) or who are entitled to receive
         any dividend or other distribution, or any right to subscribe for,
         purchase or otherwise acquire any shares of stock of any class or any
         other securities or property, or to receive any other right; or

                  (b) any capital reorganization of the Company, any
         reclassification or recapitalization of the capital stock of the
         Company or any transfer of all or substantially all of the assets of
         the Company to any other person or any consolidation or merger
         involving the Company and any other person; or

                  (c) any voluntary or involuntary dissolution, liquidation or
         winding up of the Company,

the Company shall mail to the holder of this Warrant a notice stating the date
or expected date on which any such record is to be taken and, if it relates to a
meeting (or action by written consent), the matters to be considered at such
meeting (or to be approved by such consent), or the amount and character or such
dividend, distribution or right, or the nature of such reorganization,
reclassification, transfer, merger, consolidation, dissolution, liquidation or
winding-up. Such notice shall be given at least 14 days prior to the date
therein specified.

         6. Exchange of Warrant. Upon surrender for exchange of this Warrant,
properly endorsed, to the Company, the Company at its expense will issue and
deliver to or upon the order of the holder thereof a new Warrant of like tenor,
in the name of such holder or as such holder (upon payment by such holder of any
applicable transfer taxes) may direct, calling in the aggregate on the face or
faces thereof for the number of shares of Common Stock called for on the face or
faces of the Warrant so surrendered.

         7. Replacement of Warrant. Upon receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of any such loss, theft, or destruction, upon
delivery of an indemnity agreement reasonably satisfactory in form and amount to
the Company or, in the case of any such mutilation, upon surrender and
cancellation of such Warrant, the Company at its expense will execute and
deliver, in lieu thereof, a new Warrant of like tenor.

         8. Remedies. The Company stipulates that the remedies at law of the
holder of this Warrant in the event of any default or threatened default by the
Company in the performance of or compliance with any of the terms of this
Warrant are not and will not be adequate, and that such terms may be
specifically enforced by a decree for the specific performance of any agreement
contained herein or by an injunction against a violation of any of the terms
hereof or otherwise. This remedy of specific enforcement shall not be exclusive,
and shall be in addition to any other remedy which the holder hereof may have.

         9. Ownership of Warrant. Until this Warrant is transferred on the books
of the Company, the Company may treat the person in whose name this Warrant is
issued as the absolute owner hereof for all purposes, notwithstanding any notice
to the contrary, except that, if and when this Warrant is properly assigned in
blank, the Company may (but shall not be obligated to) treat the bearer hereof
as the absolute owner of this Warrant for all purposes, notwithstanding any
notice to the contrary. This Warrant, if properly assigned, may be exercised by
a new holder without first having a new Warrant issued.

         10. Notices. All notices, consents and other communications under this
Warrant shall be in writing and shall be deemed given when delivered personally

to the Company by merger, consolidation, or acquisition of all or substantially
all of the Company's assets.

         12. Registration Rights. The initial holder of this Warrant (and
certain assignees thereof) is entitled to the benefit of such registration

Warrant as are set forth in the Stock Purchase Agreement and that certain Second

                  (b) This Warrant shall be construed and enforced in accordance

To:      Purchasers of Purchased Securities
         named on Schedule 2.1 to the
         Securities Purchase Agreement

         Re:  AirNet Communications Corporation

Ladies and Gentlemen:

         We have acted as counsel to AirNet Communications Corporation, a
Delaware corporation (the "COMPANY"), in connection with the issuance and sale
of up to 955,414 shares of Series B Convertible Preferred Stock, $.01 par value
per share, of the Company (the "SERIES B PREFERRED SHARES") and warrants to
purchase up to 2,866,242 shares of the Company's authorized but unissued Common
Stock, $0.001 par value per share (the "WARRANTS" and, together with the Series
B Preferred Shares, collectively the "PURCHASED SECURITIES"), to the Purchasers
named on SCHEDULE 2.1 to that certain Securities Purchase Agreement (the
"SECURITIES PURCHASE AGREEMENT") dated as of April 2, 2001 among the Company and
the Purchasers (the "OFFERING"). This opinion is being furnished to you pursuant
to Section 5.5 of the Securities Purchase Agreement. All capitalized terms used
but not otherwise defined herein shall have the respective meanings ascribed to
such terms in the Securities Purchase Agreement.

         We have examined the following documents:

                  hereof between the Company and Tandem PCS Instruments, L.P.,
                  and Information Rights Letter Agreement dated as of the date
                  hereof between the Company and Mellon Ventures, L.P.
                  (collectively, the "INVESTOR RIGHTS AGREEMENTS");

         (g)      Certificate of Incorporation of the Company, certified by the
                  Delaware Secretary of State as of April ___, 2001, as amended

                  Preferred Stock (the "CHARTER AMENDMENT"), certified by the
                  Delaware Secretary of State as of May ___, 2001 (collectively,
                  the "CHARTER");
<PAGE>   75
         (h)      Certificate of the Delaware Secretary of State dated April
                  ___, 2001 as to the valid legal existence of the Company as of
                  such date;

         (i)      By-laws of the Company, certified by the Secretary of the
                  Company as of the date hereof (the "BY-LAWS");

         (j)      Resolutions of the Company's Board of Directors authorizing
                  the issuance and sale of the Purchased Securities and the
                  other transactions contemplated by the Securities Purchase
                  Agreement, certified by the Secretary of the Company as of the
                  date hereof; and

         (k)      Resolutions approved by the stockholders of the Company in
                  connection with the stockholder approval of the issuance and
                  sale of the Purchased Securities and the other transactions
                  contemplated by the Securities Purchase Agreement, certified
                  by the Secretary of the Company as of the date hereof.

         The documents described in clauses (a) through (f) above are
collectively referred to as the "INVESTMENT DOCUMENTS".

         We also have examined such records and proceedings of the Company, have
made such searches and examined such other documents, statutes, public records
and certificates of officers of the Company and of public officials, and have
considered such questions of law, as we have considered necessary in order to
enable us to give the opinions herein expressed. However, in connection with the
opinion provided in paragraph 8 below, we advise you that we have not conducted
a search of the dockets of all courts or other governmental entities or
undertaken a judgment search for judgments against the Company in all
jurisdictions, where there could exist evidence of any litigation, proceeding or
investigation at law or in equity or in arbitration pending or threatened
against the Company.

         The opinions herein expressed relate only to the laws of the State of
Florida, the General Corporation Law of the State of Delaware and the federal
laws of the United States.

         In giving the opinions herein expressed, we have assumed the legal
capacity of all natural persons, the genuineness of all signatures (other than
those on behalf of the Company) appearing on the documents examined by us, the
authenticity and completeness of all documents submitted to us as originals and
the conformity to the originals of all documents submitted to us as certified,
notarized, conformed or photostatic copies or facsimiles. With respect to all
matters of fact (including factual conclusions and characterizations and
descriptions of purpose, intention, or other state of mind), we have relied
entirely upon the representations of the parties set forth in the Investment
Documents and representations and certifications of officers of the Company set
forth in the President and Chief Executive Officer's Certificate and the
Officer's Certificate (collectively, the "OFFICER'S CERTIFICATES") attached as
Exhibit A hereto, and have assumed the accuracy of those representations and
certificates. The opinions expressed below are made in reliance upon the
accuracy of the representations and other factual information contained in the
Investment Documents and Officer's Certificates and otherwise obtained during
our examination of the documents and other matters described above. Expect to
the extent expressly set forth herein, however, we have not undertaken any
independent investigation to determine the

                                      -2-
<PAGE>   76
existence or absence of such facts, and no inference as to our knowledge of the
existence or absence of such facts should be drawn from our representation of
the Company.

         When an opinion or other statement set forth herein is given to our
knowledge, with reference to matters of which we are aware or that are known to
us, or with a similar qualification, the relevant knowledge or awareness is
limited solely to the actual knowledge of the individual lawyers who are
currently partners or employees in this firm who have participated directly in
the specific transactions to which this opinion letter relates or who represent
the Company on a regular basis.

         We have also assumed the due authorization, execution and delivery by
the Purchasers and the Escrow Agent of each of the Investment Documents to which
they are a party and that each of the Investment Documents to which they are a
party is enforceable against them.

         The opinions express below are subject to the following qualifications:

         (a) The validity and enforceability of the Investment Documents may be
subject to and affected by applicable bankruptcy, insolvency, fraudulent
conveyance, equitable subordination, reorganization, arrangement, moratorium,
avoidance or other laws relating to or affecting the rights of creditors
generally.

         (b) The validity and enforceability of the Investment Documents and
particular provisions thereof are subject to or may be affected by limitations
imposed by general principles of equity and the availability of equitable
remedies (regardless of whether enforcement is considered in proceedings at law
or in equity) and by limitations on the availability of specific performance,
injunctive relief or other equitable remedies.

         (c) The validity and enforceability of the Investment Documents may be
subject to or affected by statutory or decisional law limiting or rendering
ineffective obligations to indemnify or the waiver or release of rights or
defenses.

         (d) Certain rights, remedies, forfeitures, penalties, waivers or
elections contained in the Investment Documents may be rendered ineffective or
limited by applicable laws or judicial decisions governing such provisions, but
such laws and judicial decisions do not, in our opinion, make the Investment
Documents inadequate for the substantive realization of the benefit intended to
be provided thereby.

         Based and relying upon and subject to the foregoing, we are of the
opinion that:

         1. The Company is a corporation duly incorporated, validly existing and
in good standing under the laws of the State of Delaware.

         2. The Company has the corporate power and authority to carry on its
business as presently conducted, to enter into and perform each of the
Investment Documents, to issue, sell and deliver the Purchased Securities and to
issue and deliver the Common Stock upon conversion or exercise of the Purchased
Securities.

                                      -3-
<PAGE>   77
         3. All necessary corporate and stockholder action has been taken under
Delaware law and under the Charter and By-Laws by or on behalf of the Company to
authorize the execution, delivery and performance of each of the Investment
Documents. Each of the Investment Documents has been duly executed and delivered
by or on behalf of the Company and constitutes a legal, valid and binding
obligation of the Company, enforceable against it in accordance with their
respective terms.

         4. The execution and delivery by the Company of the Investment
Documents and the consummation of the transactions contemplated thereby,
including, without limitation, the issuance of the Purchased Securities in
accordance with the Securities Purchase Agreement and the issuance of the Common
Stock upon the conversion or exercise of the Purchased Securities, do not and
will not: (i) conflict with the Charter or By-laws of the Company, (ii) violate
any judgment, decree, order, writ, law, statute, rule or regulation known to us
to be applicable to the Company, or (iii) constitute a default under any
material agreement known to us to which the Company is a party or by which it is
bound.

         5. The Charter Amendment has been duly authorized by the Company and
duly filed with the Delaware Secretary of State, has become effective and is
legally valid, binding and enforceable against the Company.

         6. Each of the Purchased Securities has been duly authorized and, upon
issuance, delivery and payment for the Preferred Shares in accordance with the
Securities Purchase Agreement, such shares will be duly issued, fully paid and
non-assessable and not subject to any preemptive rights of the holders of any
other class or series of capital stock of the Company under the Charter or
By-laws or any agreement known to us to which the Company is a party or by which
it is bound.

         7. The shares of Common Stock issuable upon the conversion or exercise
of Purchased Securities have been duly authorized, have been duly and properly
reserved for issuance and upon issuance, (assuming full payment for the shares
of Common Stock issuable upon exercise of the Warrants in accordance with the
terms of the Warrants) such shares of Common Stock will be duly issued, fully
paid and non-assessable and not subject to any preemptive rights of the holders
of any other class or series of capital stock of the Company under the Charter
or By-laws or any agreement known to us to which the Company is a party or by
which it is bound.

         8. Except as disclosed in SCHEDULE 3.9 of the Securities Purchase
Agreement, we have no knowledge of any litigation, proceeding or investigation
at law or in equity or in arbitration pending or threatened against the Company
which would reasonably be expected to have a Material Adverse Effect on the
Company or which would materially and adversely affect the validity or
enforceability of, or the authority of the Company to perform its obligations
under, the Investment Documents.

         9. All material consents, approvals and authorizations required to be
obtained by the Company from any governmental authority or agency in connection
with the issuance of the Purchased Securities, or the Common Stock issuable upon
conversion or exercise of the Purchased Securities (assuming conversion or
exercise of the Purchased Securities on the date

                                      -4-
<PAGE>   78
hereof), have been obtained or made, other than the following: (i) filings
pursuant to Regulation D under the Securities Act; and (ii) required
registration, qualification or filings under any state securities or "Blue Sky"
laws or regulations thereunder.

         We have participated in advising the Company as to the requirements of
the Securities Act of 1933, as amended (the "Securities Act"), and the
applicable rules and regulations thereunder. We also have participated in
conferences with officers and other representatives of the Company, at which
matters related to the Offering were discussed. There is no assurance that all
possible material facts as to the Company were disclosed at such conferences or
that our familiarity with the Company's business is such that we have
necessarily recognized the materiality of such facts that were disclosed.
Although we have made certain inquiries and investigations in connection with
the Offering, we have not, except with respect to matters expressly covered by
this opinion, independently checked or verified the accuracy or completeness of
the information provided by the Company and the limitations inherent in the role
of outside counsel are such that we cannot and do not assume responsibility for
or pass on the accuracy or completeness of such information. Subject to the
foregoing, nothing has come to our attention to lead us to believe that the
Company has done anything that would render unavailable the exemption from
registration under Regulation D under the Securities Act, or the exemption from
registration under the Florida Securities and Investor Protection Act, in
connection with the Offering, it being understood that no opinion is expressed
as to any subsequent resale of the Series B Preferred Shares or the Warrants or
the Common Stock issuable upon conversion or exercise of the Series B Preferred
Shares or the Warrants, or as to compliance with any state (other than Florida)
securities laws, rules, regulations or orders.

         The opinions expressed herein are limited in all respects to applicable
law as existing on the date hereof. We render no opinion on matters except as
specifically stated. In rendering this opinion letter, we do not undertake to
advise you or update you of any change in any applicable law or any fact that
may occur after the date hereof or to supplement this opinion to reflect any
facts or circumstances which may hereafter come to our attention, including
changes in laws which may hereafter occur.

         This opinion letter is furnished by us to you solely for your benefit
with respect to the transactions contemplated by the Investment Documents. This
opinion letter may not be relied upon by any other person or entity or for any
other purpose without, in each case, our express written consent. This opinion
is not to be referred to or quoted in any document, report or financial
statement, or filed with, or delivered to, any governmental agency or other
person or entity, without our prior written consent in each instance.

                                     Very truly yours,

                                     EDWARDS & ANGELL, LLP

                            CLOSING ESCROW AGREEMENT

         THIS CLOSING ESCROW AGREEMENT (this "AGREEMENT") is made as of April 2,
2001 among AirNet Communications Corporation (the "COMPANY"), the entities
designated as Purchaser on the signature page hereto (collectively,
"PURCHASERS") and SunTrust Bank ("ESCROW AGENT").

                                    Recitals

         The Company and Purchasers are parties to the Securities Purchase
Agreement dated as of the date hereof (the "PURCHASE AGREEMENT") relating to the
purchase and sale of shares of the Company's authorized but unissued Series B
Convertible Preferred Stock, $0.01 par value (the "PREFERRED SHARES") and
certain warrants to purchase shares of the Company's authorized but unissued
Common Stock, $0.001 par value per share, described therein (the "WARRANTS" and,
together with the Preferred Shares, the "PURCHASED SECURITIES"). In connection
with the consummation of the Purchase Agreement, Purchasers are depositing the
Escrow Amount (as defined herein) with the Escrow Agent to be held and released
as set forth herein.

                                    Agreement

         NOW, THEREFORE, the Company, Purchasers and Escrow Agent hereby agree
that, in consideration of the mutual promises and covenants contained herein,
Escrow Agent shall hold in escrow and shall distribute the Escrow Funds (as
defined herein) in accordance with and subject to the following Instructions and
Terms and Conditions:

I.       INSTRUCTIONS

         1. Escrow Account. The Escrow Agent has established the account or
accounts identified on Exhibit A attached hereto (collectively, the "ESCROW
ACCOUNT") into which Purchasers have deposited, or simultaneously with the
execution hereof will deposit, the Escrow Amount set forth on Exhibit A attached
hereto (the "ESCROW AMOUNT"); provided, that the obligation of each of
Purchasers SCP Private Equity Partners II, L.P. and Tandem PCS Investments, L.P.
to fund up to $5,000,000 of its portion of the Escrow Account may be delayed for
up to eleven (11) business days following the date hereof in accordance with
Section 2.2(a) of the Purchase Agreement (the "DELAYED FUNDING"). The foregoing
funds, plus all interest, dividends and other distributions and payments thereon
(collectively the "DISTRIBUTIONS"), received by Escrow Agent are collectively
referred to herein as the "ESCROW FUNDS." The Escrow Agent shall hold and
disburse the Escrow Funds as set forth in this Agreement. During the time that
the Escrow Funds are in escrow hereunder, the Escrow Amount shall not be deemed
to have been delivered to the Company.

         2. Distribution of Escrow Funds. The Escrow Agent shall promptly
release the Escrow Funds to the appropriate parties as described below in the
following circumstances:
<PAGE>   80
            (a) upon receipt by the Escrow Agent of written notice (the "CLOSING
NOTICE") from the Company of the satisfaction of all of the conditions to
closing specified in Articles V and VIII of the Purchase Agreement (other than
delivery of the Preferred Shares and Warrants required by Section 5.8 of the
Purchase Agreement and the delivery of the purchase price therefor to the
Company, but including without limitation evidence of approval of a majority of
the Company's common shares outstanding of the transactions contemplated by the
Purchase Agreement as may be required by the rules and regulations of the Nasdaq
Stock Market Inc.), the Escrow Agent shall, on the Closing Date specified in the
Purchase Agreement (i) disburse the Escrow Amount to or at the direction of the
Company (in accordance with the wire transfer instructions of the Company set
forth on Exhibit B attached hereto or such other written instructions as the
Company may give to the Escrow Agent), and (ii) disburse all Distributions, pro
rata in relation to the principal amount of the Escrow Funds received from each
Purchaser (and taking into account any Delayed Funding), to or at the direction
of the Purchasers (to each in accordance with their respective wire transfer
instructions set forth on Exhibit B attached hereto or such other written
instructions as the Purchasers may give to the Escrow Agent);

            (b) if the Escrow Agent does not receive the Closing Notice on or
before June 30, 2001, then on the next succeeding business day, the Escrow Agent
shall, automatically and without any need for further action by any party,
disburse (i) the principal amount of the Escrow Funds to or at the direction of
the Purchasers from whom such funds were received; and (ii) all Distributions,
pro rata in relation to the principal amount of the Escrow Funds received from
each Purchaser (and taking into account any Delayed Funding), to or at the
direction of the Purchasers (in the case of clauses (i) and (ii), to each in
accordance with their respective wire transfer instructions set forth on Exhibit
B attached hereto or such other written instructions as the Purchasers may give
to the Escrow Agent);

            (c) upon receipt by the Escrow Agent of written notice (the
"TERMINATION NOTICE") either (A) from the Company or the Purchasers as a result
of the termination of the Purchase Agreement under Article XII thereof or (B)
from the Purchasers as a result of a failure by the Company's qualified
independent auditors to issue an unqualified audit report in connection with the
Company's financial statements for the year ended December 31, 2000 included in
the Company's annual report on Form 10-K for such year, then on the next
business day following the Escrow Agent's receipt of the Termination Notice, the
Escrow Agent shall, automatically and without any need for further action by any
party, disburse (i) the principal amount of the Escrow Funds to or at the
direction of the Purchasers from whom such funds were received; and (ii) all
Distributions, pro rata in relation to the principal amount of the Escrow Funds
received from each Purchaser (and taking into account any Delayed Funding), to
or at the direction of the Purchasers (in the case of clauses (i) and (ii), to
each in accordance with their respective wire transfer instructions set forth on
Exhibit B attached hereto or such other written instructions as the Purchasers
may give to the Escrow Agent);

            (d) if the Escrow Agent receives joint written instructions from the
Company and the Purchasers directing the Escrow Agent to disburse the Escrow
Funds, then the Escrow Agent shall disburse the Escrow Funds in accordance with
such instructions; and

                                      -2-
<PAGE>   81
            (e) if the Escrow Agent receives a final order of a court of
competent jurisdiction authorizing the Escrow Agent to disburse the Escrow
Funds, then the Escrow Agent shall disburse the Escrow Funds in accordance with
such order.

            3. Investment of Escrow Funds. The Escrow Agent shall invest or
reinvest the Escrow Funds, without distinction between principal and income, in
the account set forth on Exhibit A attached hereto or as directed in writing by
the Company and the Purchasers. The Escrow Agent shall have no liability for any
loss arising from or related to any such investment other than in accordance
with paragraph II.5 hereof. For tax purposes, interest and other income earned
on the Escrow Funds shall be reported as income of the party to whom the
Distributions are disbursed pursuant to paragraph I.2 hereof. Neither the
Company nor any Purchaser has any right to receive, pledge, borrow or otherwise
obtain the benefits of the Escrow Funds at any time while held in escrow in
accordance with this Agreement.

II.      TERMS AND CONDITIONS

         1. The Company hereby covenants and agrees with the Purchasers that the
Company will deliver to each of the Purchasers, at the address of each specified
on Exhibit C hereto, a copy of the notice to the Escrow Agent specified in
paragraph I.2(a) of this Escrow Agreement concurrently with or prior to delivery
of such notice to the Escrow Agent, together with evidence of shareholder
approval of the transactions specified in the Purchase Agreement from the
Company's proxy solicitation agent.

         2. The duties, responsibilities and obligations of the Escrow Agent
shall be limited to those expressly set forth herein and no duties,
responsibilities or obligations shall be inferred or implied. The Escrow Agent
shall not be subject to, nor required to comply with, any other agreement
between or among any or all of the Company and the Purchasers or to which the
Company and the Purchasers are a party, even though reference thereto may be
made herein, or to comply with any direction or instruction (other than those
contained herein or delivered in accordance with this Escrow Agreement) from the
Company or the Purchasers or any entity acting on its or their behalf. The
Escrow Agent shall not be required to, and shall not, expend or risk any of its
own funds or otherwise incur any financial liability in the performance of any
of its duties hereunder.

         3. This Agreement is for the exclusive benefit of the parties hereto
and their respective successors hereunder, and shall not be deemed to give,
either express or implied, any legal or equitable right, remedy, or claim to any
other entity or person whatsoever.

         4. If at any time the Escrow Agent is served with any judicial or
administrative order, judgment, decree, writ or other form of judicial or
administrative process which in any way affects Escrow Funds (including but not
limited to orders of attachment or garnishment or other forms of levies or
injunctions or stays relating to the transfer of the Escrow Funds), the Escrow
Agent is authorized to comply therewith in any manner as it or its legal counsel
of its own choosing deems appropriate; and if the Escrow Agent complies with any
such judicial or administrative order, judgment, decree, writ or other form of
judicial or administrative process,

                                      -3-
<PAGE>   82
the Escrow Agent shall not be liable to any of the parties hereto or to any
other person or entity even though such order, judgment, decree, writ or process
may be subsequently modified or vacated or otherwise determined to have been
without legal force or effect.

         5. (a) The Escrow Agent shall not be liable for any action taken or
omitted or for any loss or injury resulting from its actions or its performance
or lack of performance of its duties hereunder in the absence of gross
negligence or willful misconduct on its part. In no event shall the Escrow Agent
be liable (i) for acting in accordance with or relying upon any instruction,
notice, demand, certificate or document from the Company or the Purchasers or
any entity acting on behalf of the Company or the Purchasers, (ii) for any
consequential, punitive or special damages, (iii) for the acts or omissions of
its nominees, correspondents, designees, subagents or subcustodians, or (iv) for
an amount in excess of the value of the Escrow Funds, valued as of the date of
deposit.

            (b) If any fees, expenses or costs incurred by, or any obligations
owed to, the Escrow Agent hereunder are not promptly paid when due, the Company
shall be solely responsible for reimbursing the Escrow Agent and the Escrow
Agent may reimburse itself therefor only from Escrow Funds released from escrow
to the Company pursuant to this Agreement and may sell, convey or otherwise
dispose of any such property for such purpose. The Company shall indemnify,
defend and save the Purchasers harmless of, from and against any and all fees,
expenses and costs incurred by the Escrow Agent in connection with its
obligations under this Escrow Agreement.

            (c) The Escrow Agent may consult with legal counsel at the sole
expense of the Company as to any matter relating to this Escrow Agreement, and
the Escrow Agent shall not incur any liability in acting in good faith in
accordance with any advice from such counsel.

            (d) The Escrow Agent shall not incur any liability for not
performing any act or fulfilling any duty, obligation or responsibility
hereunder by reason of any occurrence beyond the control of the Escrow Agent
(including but not limited to any act or provision of any present or future law
or regulation or governmental authority, any act of God or war, or the
unavailability of the Federal Reserve Bank wire or telex or other wire or
communication facility).

         6. Unless otherwise specifically set forth herein, the Escrow Agent
shall proceed as soon as practicable to collect any checks or other collection
items at any time deposited hereunder. All such collections shall be subject to
the Escrow Agent's usual collection practices or terms regarding items received
by the Escrow Agent for deposit or collection. The Escrow Agent shall not be
required, or have any duty, to notify anyone of any payment or maturity under
the terms of any instrument deposited hereunder, nor to take any legal action to
enforce payment of any check, note or security deposited hereunder or to
exercise any right or privilege which may be afforded to the holder of any such
security.

         7. The Escrow Agent shall provide to the Company and the Purchasers
monthly statements identifying transactions, transfers or holdings of the Escrow
Funds and each such statement shall be deemed to be correct and final upon
receipt thereof by the Company and the

                                      -4-
<PAGE>   83
Purchasers unless the Escrow Agent is notified in writing to the contrary within
thirty (30) business days of the date of such statement.

         8. The Escrow Agent shall not be responsible in any respect for the
form, execution, validity, value or genuineness of documents or securities
deposited hereunder, or for any description therein, or for the identity,
authority or rights of persons executing or delivering or purporting to execute
or deliver any such document, security or endorsement.

         9. Notices, instructions or other communications shall be in writing
and shall be given via facsimile, hand delivery, overnight delivery (via a
nationally recognized overnight courier service), or first-class mail (postage
prepaid) to the address set forth in Exhibit C attached hereto (or to such other
address as may be substituted therefor by written notification to the Escrow
Agent, the Company or the Purchasers). Notices to the Escrow Agent shall be
deemed to be given when actually received by the Escrow Agent's Corporate Trust
Department. The Escrow Agent is authorized to comply with and rely upon any
notices, instructions or other communications believed by it to have been sent
or given by the Company or the Purchasers or by a person or persons authorized
by the Company or the Purchasers. Whenever under the terms hereof the time for
giving a notice or performing an act falls upon a Saturday, Sunday, or banking
holiday, such time shall be extended to the next day on which the Escrow Agent
is open for business.

         10. The Company shall be solely liable for and shall reimburse and
indemnify the Escrow Agent and hold the Escrow Agent harmless from and against
any and all claims, losses, liabilities, costs, damages or expenses (including
reasonable attorneys' fees and expenses) (collectively, "LOSSES") arising from
or in connection with or related to this Escrow Agreement or being the Escrow
Agent hereunder (including but not limited to Losses incurred by the Escrow
Agent in connection with its successful defense, in whole or in part, of any
claim of gross negligence or willful misconduct on its part), provided, however,
that nothing contained herein shall require the Escrow Agent to be indemnified
for Losses caused by its gross negligence or willful misconduct.

         11. (a) The Company and the Purchasers may remove the Escrow Agent at
any time by giving to the Escrow Agent thirty (30) calendar days' prior notice
in writing signed by the Company and each of the Purchasers. The Escrow Agent
may resign at any time by giving to the Company and the Purchasers fifteen (15)
calendar days' prior written notice thereof.

            (b) Within ten (10) calendar days after giving the foregoing notice
of removal to the Escrow Agent or receiving the foregoing notice of resignation
from the Escrow Agent, the Company and the Purchasers shall jointly agree on and
appoint a successor Escrow Agent. If a successor Escrow Agent has not accepted
such appointment by the end of such 10-day period, the Escrow Agent may, in its
sole discretion, deliver the Escrow Funds to the Company and the Purchasers at
the addresses provided herein or may apply to a court of competent jurisdiction
for the appointment of a successor Escrow Agent or for other appropriate relief.
The costs and expenses (including reasonable attorneys' fees and expenses)
incurred by the Escrow Agent in

                                      -5-
<PAGE>   84
connection with such proceeding shall be paid by, and be deemed the sole
obligation of, the Company.

            (c) Upon receipt of the identity of the successor Escrow Agent, the
Escrow Agent shall either deliver the Escrow Funds then held hereunder to the
successor Escrow Agent, less the Escrow Agent's fees, costs and expenses or
other obligations owed to the Escrow Agent, or hold such Escrow Funds (or any
portion thereof), pending distribution, until all such fees, costs and expenses
or other obligations are paid.

            (d) Upon delivery of the Escrow Funds to a successor Escrow Agent,
the Escrow Agent shall have no further duties, responsibilities or obligations
hereunder.

         12. (a) In the event of any ambiguity or uncertainty hereunder or in
any notice, instruction or other communication received by the Escrow Agent
hereunder, the Escrow Agent may, in its sole discretion, refrain from taking any
action other than retain possession of the Escrow Funds, unless the Escrow Agent
receives written instructions, signed by the Company and each Purchaser, which
eliminates such ambiguity or uncertainty.

            (b) In the event of any dispute between or conflicting claims by or
among the Company and the Purchasers and/or any other person or entity with
respect to any Escrow Funds, the Escrow Agent shall be entitled, in its sole
discretion, to refuse to comply with any and all claims, demands or instructions
with respect to such Escrow Funds so long as such dispute or conflict shall
continue, and the Escrow Agent shall not be or become liable in any way to the
Company or any Purchaser for failure or refusal to comply with such conflicting
claims, demands or instructions. The Escrow Agent shall be entitled to refuse to
act until, in its sole discretion, either (i) such conflicting or adverse claims
or demands shall have been determined by a final order, judgment or decree of a
court of competent jurisdiction, which order, judgment or decree is not subject
to appeal, or settled by agreement between the conflicting parties as evidenced
in a writing satisfactory to the Escrow Agent or (ii) the Escrow Agent shall
have received security or an indemnity satisfactory to it sufficient to hold it
harmless from and against any and all Losses which it may incur by reason of so
acting. The Escrow Agent may, in addition, elect, in its sole discretion, to
commence an interpleader action or seek other judicial relief or orders as it
may deem, in its sole discretion, necessary. The costs and expenses (including
reasonable attorneys' fees and expenses) incurred in connection with such
proceeding shall be paid by, and shall be deemed the sole obligation of, the
Company.

         13. This Agreement shall be interpreted, construed, enforced and
administered in accordance with the internal substantive laws (and not the
choice of law rules) of the State of New York. Each of the Company and the
Purchasers hereby submits to the personal jurisdiction of and each agrees that
all proceedings relating hereto shall be brought in courts located within the
City and State of New York or elsewhere as the Escrow Agent may select. Each of
the Company and the Purchasers hereby waives the right to trial by jury and to
assert counterclaims in any such proceedings. To the extent that in any
jurisdiction the Company or the Purchasers may be entitled to claim, for itself
or its assets, immunity from suit, execution, attachment (whether before or
after judgment) or other legal process, each hereby irrevocably agrees not to

                                      -6-
<PAGE>   85
claim, and hereby waives, such immunity. Each of the Company and the Purchasers
waives personal service of process and consents to service of process by
certified or registered mail, return receipt requested, directed to it at the
address last specified for notices hereunder, and such service shall be deemed
completed ten (10) calendar days after the same is so mailed.

         14. Except as otherwise permitted herein, this Escrow Agreement may be
modified only by a written amendment signed by all the parties hereto, and no
waiver of any provision hereof shall be effective unless expressed in a writing
signed by the party to be charged.

         15. The rights and remedies conferred upon the parties hereto shall be
cumulative, and the exercise or waiver of any such right or remedy shall not
preclude or inhibit the exercise of any additional rights or remedies. The
waiver of any right or remedy hereunder shall not preclude the subsequent
exercise of such right or remedy.

         16. Each of the Company and the Purchasers hereby represents and
warrants, as to itself only, (a) that this Escrow Agreement has been duly
authorized, executed and delivered on its behalf and constitutes its legal,
valid and binding obligation and (b) that the execution, delivery and
performance of this Escrow Agreement by the Company and the Purchasers, as
applicable, do not and will not violate any applicable law or regulation.

         17. The invalidity, illegality or unenforceability of any provision of
this Agreement shall in no way affect the validity, legality or enforceability
of any other provision; and if any provision is held to be enforceable as a
matter of law, the other provisions shall not be affected thereby and shall
remain in full force and effect.

         18. This Agreement (together with the Purchase Agreement, as between
the Purchasers and the Company) shall constitute the entire agreement of the
parties with respect to the subject matter and supersedes all prior oral or
written agreements in regard thereto. In the event of any inconsistency between
the terms of this Escrow Agreement and the terms of the Purchase Agreement with
respect to the subject matter hereof, the terms of this Escrow Agreement shall
prevail.

         19. This Escrow Agreement shall terminate upon the distribution of all
Escrow Funds. The provisions of these Terms and Conditions shall survive
termination of this Escrow Agreement and/or the resignation or removal of the
Escrow Agent.

         20. No printed or other material in any language, including
prospectuses, notices, reports, and promotional material which mentions the
Escrow Agent by name or the rights, powers, or duties of the Escrow Agent under
this Agreement shall be issued by any other parties hereto, or on such party's
behalf, without the prior written consent of the Escrow Agent.

         21. The headings contained in this Escrow Agreement are for convenience
of reference only and shall have no effect on the interpretation or operation
hereof.

<PAGE>   86
         22. This Escrow Agreement may be executed by each of the parties hereto
in any number of counterparts, each of which counterpart, when so executed and
delivered, shall be deemed to be an original and all such counterparts shall
together constitute one and the same agreement.

         23. The Escrow Agent does not have any interest in the Escrow Funds
deposited hereunder but is serving as escrow holder only and having only
possession thereof. The Company, alone, shall pay or reimburse the Escrow Agent
upon request for any transfer taxes or other taxes relating to the Escrow Funds
incurred in connection herewith and shall indemnify and hold harmless the Escrow
Agent against any amounts that it is obligated to pay in the way of such taxes.
Any payments of income from the Escrow Funds shall be subject to withholding
regulations then in force with respect to United States taxes. The parties
hereto will provide the Escrow Agent with appropriate W-9 forms for tax I.D.,
number certifications, or W-8 forms for non-resident alien certifications. It is
understood that the Escrow Agent shall be responsible for income reporting only
with respect to income earned on investment of funds which are a part of the
Escrow Funds and is not responsible for any other reporting. This paragraph and
paragraph II.10 hereof shall survive notwithstanding any termination of this
Escrow Agreement or the resignation of the Escrow Agent.

     Re:  Management Rights

Gentlemen:

     This letter will confirm our agreement that pursuant to and effective as of
your purchase of 318,471.33 shares of Series B Convertible Preferred Stock of
AirNet Communications Corporation (the "Company"), the Company has agreed to
contractually provide SCP Private Equity Partners II, L.P. (the "Investor")
with certain management rights with respect to the Company. The Company and the
Investor acknowledge that the provisions of this letter agreement are intended
to provide the Investor with management rights with respect to the Company
within the meaning of the Employee Retirement Income Security Act of 1974, as
amended, and the regulations promulgated thereunder. The management rights the
Investor shall possess are the following:

          The Investor shall be entitled to consult with and advise management
of the Company on significant business issues, including management's proposed
annual operating plans, and management will meet with the Investor regularly
during each year at the Company's facilities at mutually agreeable times for
such consultation and advice and to review progress in achieving such plans.

          The Investor shall have the right to examine the books and records of
the Company and inspect its facilities and may request information at
reasonable times and intervals concerning the general status of the Company's
financial condition and operations, including, but not limited to, all
financial statements, operating reports, budgets, and other financial reports,
provided that access to highly confidential proprietary information and
facilities need not be provided.

          If the Investor is not represented on the Company's Board of
Directors, the Company shall give a representative of the Investor, upon
written request, copies of all notices, minutes, consents and other material
that the Company provides to its directors, except that the representative may
be excluded from access to any material or meeting or portion thereof if the
Company believes, upon advice of counsel, that such exclusion is reasonably
necessary to preserve the attorney-client privilege, to protect highly
confidential proprietary information or for other similar reasons. Upon
reasonable notice and at a scheduled meeting of the Board of Directors or such
other time, if any, as the Board of Directors may determine in its sole
discretion, such representative may address the Board of Directors with respect
to the Investor's concerns regarding significant business issues facing the
Company.
