ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

       On December 2, 1997, The Willis Group, LLC ("The Willis Group") entered
into a Switch Agreement with the Issuer and its subsidiary (the "Switch
Agreement") pursuant to which it will receive, in exchange for certain
telecommunications switches (the "Switches"), cash, 400,000 shares of Common
Stock and a warrant for the purchase of an additional 400,000 shares of Common
Stock at $1.50 per share.

         Also, on December 2, 1997, Netco Acquisition, LLC ("Netco LLC), of
which The Willis Group is a member, and its subsidiary, Netco Acquisition Corp.
("Netco"), entered into an Agreement of Merger and Plan of Reorganization with
the Issuer and its subsidiary (the "Merger Agreement") pursuant to which Netco
LLC will receive, in exchange for its shares of Netco, (a) 2,081,633 shares of
Common Stock, (b) a number of shares of Common Stock equal to the working
capital loans made by the members of Netco LLC or their affiliates prior to the
closing, which amount is expected to be not less that $1.5 million, divided by
$1.00 and (c) 2,000 shares of Series A Preferred Stock of the Issuer (the
"Series A Preferred"). Holders of Series A Preferred will have the right to
convert their shares into shares of Common Stock initially at the rated of
833.33 shares of Common Stock per share of Series A Preferred (or the stated
value divided by $1.20), or an aggregate of 1,666,667 shares of Common Stock.
The Willis Group owns a 50% membership interest in Netco LLC and, pursuant to
prior agreement, has the right to receive the 2,081,633 shares of Common Stock
issuable under the Merger Agreement. The other consideration to be issued by the
Issuer in connection with the Merger Agreement will be distributed to the other
members of Netco LLC.

         Additionally, on December 2, 1997, The Willis Group entered into a
Stock Purchase Agreement with the Issuer (the "Stock Purchase Agreement")
pursuant to which it will purchase 4,000,000 shares of the Common Stock at a
price of $1.00 per share in cash.

         The Willis Group also beneficially holds, through Netco LLC and Netco,
a warrant to purchase 150,000 shares of Common Stock, which warrant will become
exercisable on February 1, 1998 if transactions contemplated in the agreements
described in this Item 3 are not consummated before then.

ITEM 4.  PURPOSE OF TRANSACTION.

         The Filing Persons acquired their shares of Common Stock as part of
their previously described plan to acquire control of the Issuer. The Filing
Persons currently do not intend to acquire additional shares of the Common Stock
materially above their current ownership, however, the Filing Persons intend to
review their investment in the Issuer on a continuing basis and, depending upon
the price of the Common Stock, subsequent developments affecting the Issuer, the
Issuer's business and prospects, general stock market and economic conditions,
tax considerations and other factors deemed relevant, may decide to increase or
decrease their investment in the Common Stock of the Issuer.

         On December 2, 1997, the Filing Persons entered into the agreements
described in Item 3 above (the "Agreements"). The Filing Persons intend to
control the board of directors of the Issuer as a result of its potential
acquisition of these and additional shares of Common Stock. There can be no
assurance, however, that the Filing Persons and the Issuer will complete the
transactions contemplated in the Agreements.

         Except as set forth above in this Item 4, none of the Filing Persons
nor, to the best of each Filing Person's knowledge, none of the executive
officers or directors of such Filing Persons, as applicable, has any plans or
proposals that relate to or would result in any of the actions specified in
clauses (a) through (j) of Item 4 to Schedule 13D.

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER

         (a) The Filing Persons beneficially own, directly or indirectly, the
right, in the form of currently exercisable warrants and a convertible note, or
pursuant to the Agreements, to acquire 8,081,633 shares of Common Stock of the
Issuer, which constitutes 51% of the Common Stock outstanding based on the
number of securities assumed to be outstanding on the Record Date (7,787,724) as
contained in the Issuer's Preliminary Proxy Statement on Schedule 14A, filed
confidentially with the Securities and Exchange Commission on December 9, 1997
and including as outstanding the 8,081,633 shares issuable to The Willis Group
under currently exercisable warrants, a convertible note and the Agreements.
Such securities, or the rights thereto, were acquired pursuant to the
transactions described in Item 3 hereof and the initial filing of this Schedule
13D.

         (b) Of the shares beneficially owned by the Filing Persons, The Willis
Group has, or will have, sole voting power and power to dispose of the 8,081,633
shares of Common Stock they have the right to acquire under currently
exercisable warrants, a convertible note and the Agreements and each of Messrs.
Mike Willis, Mark Willis and Harris, as 47.5%, 47.5% and 5% membership interest
owners, respectively, of The Willis Group, have shared voting and dispositive
power with respect to all such shares.

      and its Subsidiaries' employees is obligated under any contract (including
      licenses, covenants, or commitments of any nature) or other agreement, or
      subject to any judgment, decree, or order of any court or administrative
      agency, that would interfere with the use of such employee's best efforts
      to promote the interests of EqualNet or its Subsidiaries or that would
      conflict with EqualNet's or its Subsidiaries' business as presently
      conducted and as proposed to be conducted. Neither

      EqualNet's or its Subsidiaries' business by the employees of EqualNet and
      its Subsidiaries, nor the conduct of EqualNet's or its Subsidiaries'
      business as proposed to be conducted, will conflict with or result in a
      breach of the terms, conditions, or provisions of, or constitute a default
      under, any contract, covenant, or instrument under which any of such
      employees is now obligated. It is not, and will not become, necessary to
      utilize any inventions of any of EqualNet's or its Subsidiaries' employees
      (or people EqualNet and its Subsidiaries currently intends to hire) made
      prior to their employment by EqualNet and its Subsidiaries other than

      (f) CHANGES IN EMPLOYMENT ARRANGEMENTS. Neither EqualNet nor any of its
Subsidiaries shall adopt or amend (except as may be required by law) any bonus,
profit sharing, compensation, stock option, pension, retirement, deferred
compensation, employment or other employee benefit plan, agreement, trust, fund
or other arrangement for the benefit or welfare of any employee, director or
former director or employee, increase the compensation or fringe benefits of any
officer of EqualNet or any of its Subsidiaries, or, except as provided in an
existing benefit plan or in the ordinary course of business consistent with past
practice, increase the compensation or fringe benefits of any employee or former
employee or pay any benefit not required by any existing plan, arrangement or
agreement.

      (g) SEVERANCE. Neither EqualNet nor any of its Subsidiaries shall grant
any new or modified severance or termination arrangement or increase or
accelerate any benefits payable under its severance or termination pay policies
in effect on the date hereof.

      (h) OTHER ACTIONS. EqualNet shall not, and shall not permit any of its
Subsidiaries to, take any action that would, or that could reasonably be
expected to, result (i) in any of the representations and warranties of EqualNet
set forth in this Agreement becoming untrue or (ii) in any of the covenants
contained in this Agreement becoming unperformable. Pending the Closing,
EqualNet will promptly advise TWG of any action or event of which it becomes
aware which has the effect of making incorrect any of such representations or
warranties or which has the effect of rendering unperformable any of such
covenants.

      (i) VALID ISSUANCE. EqualNet covenants that the EqualNet Common Shares to
be issued by EqualNet pursuant to Section 2(b) and by EqualNet pursuant to an
exercise of the Warrant will, upon issuance and upon delivery of certificates
representing such shares, be validly issued, fully paid and nonassessable and
free from all taxes, liens and charges with respect to the issuance thereof.

      (j) GOVERNMENT REGULATIONS. EqualNet covenants that it will comply, and
will cause each of its Subsidiaries to comply, with all applicable governmental
restrictions and regulations, the failure to comply with which would have a
material adverse effect on the business or financial condition of EqualNet and
its Subsidiaries taken as a whole, and obtain and maintain in good standing all
licenses, permits and approvals from any and all governments, governmental
commissions, boards or agencies of jurisdictions in which it or any of its
Subsidiaries carries on business required in respect of the operations of
EqualNet or any of its Subsidiaries, the failure to comply with which would have
a Material Adverse Effect.

      (k) ERISA. Promptly (and in any event within 30 days) after EqualNet or
any of its Subsidiaries knows or has reason to know that a Reportable Event with
respect to any Pension Plan has occurred, that any Pension Plan is or may be
terminated, reorganized, partitioned or declared insolvent under Title IV of
ERISA or that EqualNet or any of its Subsidiaries will or may incur any
liability to or on account of a Pension Plan under Sections 4062, 4063, 4064,
4201 or 4204 of ERISA, EqualNet will deliver to TWG a certificate of the chief
financial officer of EqualNet setting forth information as to such occurrence
and what action, if any, EqualNet is required or proposes to take with respect
thereto, together with any notices concerning such occurrences which are (a)
required to be filed by EqualNet or the plan administrator of any such Pension
Plan controlled by EqualNet or its Subsidiaries, with the PBGC or (b) received
by EqualNet or its Subsidiaries from any

                                     16
<PAGE>   20
plan administrator of a multiemployer or other Pension Plan not under their
control. EqualNet shall furnish to TWG a copy of each annual report (Form 5500
Series) of any Pension Plan received or prepared by EqualNet or any of its
Subsidiaries. Each annual report and any notice required to be delivered
hereunder shall be delivered no later than 10 days after the later of the date
such report or notice is filed with the Internal Revenue Service or the PBGC or
the date such report or notice is received by EqualNet or any of its
Subsidiaries, as the case may be.

      (l) CORPORATE EXISTENCE; MAINTENANCE OF PROPERTIES. EqualNet covenants
that it (i) will do or cause to be done all things reasonably necessary to
preserve and keep in full force and effect the corporate existence and material
rights of EqualNet and all of its Subsidiaries, (ii) will cause its properties
and the properties of its Subsidiaries used or useful in the conduct of their
respective businesses to be maintained and kept in good condition, repair and
working order and will use commercially reasonable efforts to cause to be made
all necessary repairs, renewals, replacements, betterments and improvements
thereto, and (iii) will, and will cause each of its Subsidiaries to, qualify and
remain qualified to conduct business in each jurisdiction where the nature of
the business or the ownership of property by EqualNet or such Subsidiary may
require such qualification and where the failure to so qualify would have a
Material Adverse Effect.

      (m) INSURANCE. EqualNet covenants that it will maintain, and will cause
each of its Subsidiaries to maintain, with financially sound and reputable
insurance companies, funds or underwriters, insurance for EqualNet and its
Subsidiaries of the kinds, covering the risks and in the relative proportionate
amounts usually carried by companies conducting business activities similar to
those of EqualNet and its Subsidiaries.

      (n) FURTHER ASSURANCES. EqualNet covenants that it shall cooperate with
TWG and execute such further instruments and documents as TWG shall reasonably
request to carry out to the satisfaction of TWG the transactions contemplated by
this Agreement.

      (o) NOTICES OF CERTAIN EVENTS. EqualNet shall promptly give notice to TWG
(i) of any default or event of default that has not been cured within any
applicable grace period under any (y) Indebtedness of EqualNet or any of its
Subsidiaries, or (z) contractual obligation of EqualNet or any of its
Subsidiaries or (ii) of any pending or threatened litigation, investigation or
proceeding to which EqualNet or any of its Subsidiaries is or is threatened to
be a party and of which EqualNet has been given notice; provided that any such
default as specified in clause (z) above, litigation, investigation or
proceeding would have a Material Adverse Effect. Any notice delivered pursuant
to this Section 5(o) shall be accompanied by an officer's certificate specifying
the details of the occurrence referred to therein and stating what action
EqualNet proposes to take with respect thereto.

      (p) ENVIRONMENTAL LAWS. EqualNet and its Subsidiaries shall comply with
all applicable Environmental Laws the failure to comply with which would have a
Material Adverse Effect. If EqualNet or any Subsidiary shall receive written
notice that there exists a violation of Environmental Law with respect to its
operations or any real property owned, formerly owned, used, or leased thereby,
which violation could have a Material Adverse Effect, EqualNet shall immediately
notify in writing TWG. Furthermore, if EqualNet or any Subsidiary shall receive
written notice that there exists a violation of Environmental Law with respect
to its operations or any real property owned, formerly owned, used or leased
thereby, which violation could have a Material Adverse Effect,

                                     17
<PAGE>   21
EqualNet shall within the time period permitted by the applicable governmental
authority (unless otherwise contested by EqualNet in good faith) remove or
remedy such violation in accordance with all applicable Environmental Laws
unless the Board of Directors of EqualNet makes a good faith determination that
it would be in the best interest of EqualNet to delay the remedy of such
violation, so long as no Material Adverse Effect is suffered by EqualNet or its
Subsidiaries during such delay.

      (q) REGISTRATION RIGHTS. EqualNet hereby grants to TWG the same rights to
cause EqualNet to register the EqualNet Common Shares to be issued pursuant to
Section 2(b) and pursuant to an exercise of the Warrant under state and federal
securities laws and all such other rights as set forth in Section 4.1.11 of the
Note and Warrant Purchase Agreement at any time from and after the Closing Date;
provided, such registration rights shall be effective immediately upon the
Closing Date notwithstanding whether or not the Note or Warrants under the Note
and Warrant Purchase Agreement have been converted or exercised, as the case may
be.

      (r)   SHAREHOLDER APPROVAL; PREPARATION OF PROXY STATEMENTS.

            (i) EqualNet shall, as soon as practicable following the execution
      and delivery of this Agreement duly call, give notice of, convene and hold
      a meeting of EqualNet's shareholders (the "Shareholders Meeting") for the
      following purposes: (i) approving this Agreement, the issuance of the
      Shares and the transactions contemplated hereby, (ii) ratifying the Note
      and Warrant Purchase Agreement and the transactions contemplated thereby,
      (iii) approving the Stock Purchase Agreement and the issuance of EqualNet
      Common Shares thereunder, (iv) approving Reorganization Agreement, (v)
      approving the increase in authorized shares of EqualNet Common Shares to
      55,000,000 and (vi) approving the other related transactions. EqualNet
      will, through its officers and its Board of Directors, unanimously
      recommend to its shareholders the approval and adoption of the foregoing
      transactions.

            (ii) Promptly following the date of this Agreement, EqualNet shall
      prepare and file with the Commission a proxy statement relating to the
      Shareholders Meeting (such proxy statement as amended or supplemented from
      time to time, the "Proxy Statement"). TWG shall have the right to review
      and approve the Proxy Statement prior to EqualNet filing the Proxy
      Statement with the Commission. EqualNet will use all commercially
      reasonable efforts to cause the Proxy Statement to be mailed to EqualNet's
      shareholders as promptly as practicable. EqualNet will notify TWG promptly
      of the receipt of any written or oral comments from the Commission or its
      staff and of any request by the Commission or its staff for amendments or
      supplements to the Proxy Statement or for additional information and will
      supply TWG with copies of all correspondence between EqualNet or any of
      its representatives, on the one hand, and the Commission or its staff, on
      the other hand, with respect to the Proxy Statement.

            (iii) EqualNet agrees to cause all shares of capital stock, if any,
      owned by it or any other Subsidiary or its officers and directors to be
      voted in favor of the approval and adoption of this Agreement, the Note
      and Warrant Purchase Agreement, the Stock Purchase Agreement, the
      Reorganization Agreement and the other related transactions.

                                     18
<PAGE>   22
            (iv) EqualNet will cause its transfer agent to make stock transfer
      records relating to EqualNet available to the extent reasonably necessary
      to effectuate the intent of this Agreement.

      (s) NO SOLICITATION. (i) EqualNet shall not, nor shall it permit any of
its Subsidiaries to, nor shall it authorize or permit any officer, director or
employee of EqualNet or any investment banker, attorney or other advisor, agent
or representative of EqualNet or any of its Subsidiaries to, directly or
indirectly, (1) solicit, initiate or encourage the submission of any takeover
proposal, (2) enter into any agreement (other than confidentiality and
standstill agreements in accordance with the immediately following proviso) with
respect to any takeover proposal, or (3) participate in any discussions or
negotiations regarding, or furnish to any Person any information with respect
to, or take any other action to facilitate any inquiries or the making of any
proposal that constitutes, or may be reasonably be expected to lead to, any
takeover proposal; provided, in the case of this clause (3), that prior to the
vote of shareholders of EqualNet for approval of the matters referred to in
Section 5(s) (and not thereafter if such matters are approved thereby) to the
extent required by the fiduciary obligations of the Board of Directors of
EqualNet, determined in good faith by a majority of the disinterested members
thereof based on the advice of outside counsel, EqualNet, in response to an
unsolicited superior proposal and a request for information pursuant thereto,
may furnish information to any person or "group" within the meaning of Section
13(d)(3) of the Exchange Act pursuant to a confidentiality agreement. Without
limiting the foregoing, it is understood that any violation of the restrictions
set forth in the preceding sentence by any officer, director or employee of
EqualNet or any of its Subsidiaries or any investment banker, attorney or other
advisor, agent or representative of EqualNet, whether or not such Person is
purporting to act on behalf of EqualNet or otherwise, shall be deemed to be a
material breach of this Agreement by EqualNet. For purposes of this Section
5(t), "takeover proposal" means (x) any proposal, other than a proposal by TWG
or any of its Affiliates, for a merger or other business combination involving
EqualNet, (y) any proposal or offer, other than a proposal or offer by TWG or
any of its Affiliates, to acquire from EqualNet or any of its Affiliates in any
manner, directly or indirectly, an equity interest in EqualNet or any
Subsidiary, any voting securities of EqualNet or any Subsidiary or a material
amount of the assets of EqualNet and its Subsidiaries, taken as a whole, or (z)
any proposal or offer, other than a proposal or offer by TWG or any of its
Affiliates, to acquire from the shareholders of EqualNet by tender offer,
exchange offer or otherwise more than 20% of the outstanding shares of Common
Shares.

            (ii) Neither the Board of Directors of EqualNet nor any committee
thereof shall, except in connection with the termination of this Agreement
pursuant to Section 7, (1) withdraw or modify, or propose to withdraw or modify,
in a manner adverse to TWG the approval or recommendation by the Board of
Directors of EqualNet or any such committee thereof of this Agreement or take
any action having such effect; provided, a statement by the Board of Directors
of EqualNet to its shareholders as contemplated by Rule 14e-2(a) of the Exchange
Act following TWG's receipt of a Notice of Superior Proposal (defined below)
shall not be deemed to constitute a withdrawal or modification of its
recommendation of this Agreement, or (2) approve or recommend, or propose to
approve or recommend, any takeover proposal. Notwithstanding the foregoing, in
the event that the Board of Directors of EqualNet receives a takeover proposal
that, in the exercise of its fiduciary obligations (as determined in good faith
by a majority of the disinterested members thereof based on the advice of
outside counsel), it determines to be a superior proposal, the Board of
Directors of EqualNet may withdraw or modify its approval or recommendation of
this

                                     19
<PAGE>   23
Agreement and may (subject to the following sentence) terminate this Agreement,
in each case at any time after midnight on the fifth Business Day following
TWG's receipt of written notice (a "Notice of Superior Proposal") advising TWG
that the Board of Directors of EqualNet has received a takeover proposal that it
has determined to be a superior proposal, specifying the material terms and
conditions of such superior proposal (including the proposed financing for such
proposal and a copy of any documents conveying such proposal) and identifying
the Person making such superior proposal. EqualNet may terminate this Agreement
pursuant to the preceding sentence only if the shareholders of EqualNet have not
yet voted upon the matters set forth in Section 5(s). Any of the foregoing to
the contrary notwithstanding, EqualNet may engage in discussions with any Person
or group that has made an unsolicited takeover proposal for the limited purpose
of determining whether such proposal is a superior proposal. Nothing contained
herein shall prohibit EqualNet from taking and disclosing to its shareholders a
position contemplated by Rule 14e-2(a) following TWG's receipt of a Notice of
Superior Proposal.

            (iii) For purposes of this Section 5(t), a "superior proposal" means
any BONA FIDE takeover proposal to acquire, directly or indirectly, for
consideration consisting of cash, securities or a combination thereof, all of
the EqualNet Common Shares then outstanding or all or substantially all of the
assets of EqualNet and its Subsidiaries, and otherwise on terms that a majority
of the disinterested members of the Board of Directors of EqualNet determines in
its good faith reasonable judgment (based on the advice of a financial advisor
of nationally recognized reputation, a copy of which shall be provided to TWG)
to be more favorable to EqualNet's shareholders than the transactions
contemplated by this Agreement, the Stock Purchase Agreement and the
Reorganization Agreement.

            (iv) In addition to the obligations of EqualNet set forth in clause
(ii) above, EqualNet shall promptly advise TWG orally and in writing of any
takeover proposal or any inquiry with respect to or which could lead to any
takeover proposal, the material terms and conditions of such inquiry or takeover
proposal (including the financing for such proposal and a copy of such documents
conveying such proposal), and the identity of the Person making any such
takeover proposal or inquiry.

      (t) LISTING OF COMMON STOCK. EqualNet warrants and agrees for the benefit
of the TWG that it will use commercially reasonable efforts to cause the
EqualNet Common Shares to be issued pursuant to Section 2 and pursuant to the
Warrant to be approved for listing, subject to official notice of issuance, on
the NASDAQ National Market as of the Closing Date.

      (u) ACQUISITION LOAN. TWG may elect to obtain financing for the Switches
from a bank or other third party lender, such financing to be in a principal
amount not to exceed the $5,850,000 purchase price paid by TWG for the Switches.
Any such financing shall be secured by a first priority lien and security
interest on the Switches and otherwise on terms satisfactory to TWG and EqualNet
(the "Acquisition Loan"). If a guarantee is required to obtain such loan, then
such guarantee shall be satisfactory to TWG in its sole discretion. Among other
conditions that may be applicable, any such guarantee provided by or arranged
for by TWG shall be conditioned upon EqualNet agreeing to pay TWG a guarantee
fee on the outstanding balance of the Acquisition Loan. The loan documents shall
provide that if the closing of the transaction contemplated by this Agreement
occurs,

                                     20
<PAGE>   24
then the Sub and EqualNet shall assume (or otherwise become liable on) the
Acquisition Loan and TWG shall be released from any liability on the Acquisition
Loan effective as of such closing.

      by reason of the failure of any condition precedent under Section 6(b)

      (d)   MATTERS INVOLVING THIRD PARTIES.

            (i) If any third party shall notify any Party (the "Indemnified
      Party") with respect to any matter (a "Third Party Claim") that may give
      rise to a claim for indemnification against any other Party (the
      "Indemnifying Party") under this Section 8, then the Indemnified Party
      shall promptly notify the Indemnifying Party thereof in writing; provided,
      no delay on the part of the Indemnified Party in notifying the
      Indemnifying Party shall relieve the Indemnifying Party from any
      obligation hereunder unless (and then solely to the extent) the
      Indemnifying Party thereby is prejudiced.

            (ii) The Indemnifying Party will have the right to defend the
      Indemnified Party against the Third Party Claim with counsel of the
      former's choice reasonably satisfactory to the Indemnified Party so long
      as (1) the Indemnifying Party notifies the Indemnified Party in writing
      within 15 days after the Indemnified Party has give notice of the Third
      Party Claim that the Indemnifying Party will indemnify the Indemnified
      Party from and against the entirety of any Adverse Consequences the
      Indemnified Party may suffer resulting from, arising out of, relating to,
      in the nature of, or caused by the Third Party Claim, (2) the Indemnifying
      Party

                                     24
<PAGE>   28
      provides the Indemnified Party with evidence reasonably acceptable to the
      Indemnified Party that the Indemnifying Party will have the financial
      resources to defend against the Third Party Claim and fulfill its
      indemnification obligations hereunder, (3) the Third Party Claim involves
      only money damages and does not seek an injunction or other equitable
      relief, (4) settlement of, or an adverse judgment with respect to, the
      Third Party Claim is not in the good faith judgment of the Indemnified
      Party, likely to establish a precedential custom or practice materially
      adverse to the continuing business interests of the Indemnified Party, and
      (5) the Indemnifying Party conducts the defense of the Third Party Claim
      actively and diligently.

            (iii) So long as the Indemnifying Party is conducting the defense of
      the Third Party Claim in accordance with Section 8(d)(ii), (1) the
      Indemnified Party may retain separate co-counsel at its sole cost and
      expense and participate in the defense of the Third Party Claim, (2) the
      Indemnified Party will not consent to the entry of any judgment or enter
      into any settlement with respect to the Third Party Claim without the
      prior written consent of the Indemnifying Party (not to be withheld
      unreasonably), and (3) the Indemnifying Party will not consent to the
      entry of any judgment or enter into any settlement with respect to the
      Third Party Claim without the prior written consent of the Indemnified
      Party (not to be withheld unreasonably).

            (iv) In the event any of the conditions in Section 8(d)(ii) is or
      becomes unsatisfied, however, (1) the Indemnified Party may defend
      against, and consent to the entry of any judgment or enter into any
      settlement with respect to, the Third Party Claim in any manner it
      reasonably may deem appropriate (and the Indemnified Party need not
      consult with, or obtain any consent from, the Indemnifying Party in
      connection therewith), (2) the Indemnifying Party will reimburse the
      Indemnified Party promptly and periodically for the costs of defending
      against the Third Party Claim (including reasonable attorneys' fees and
      expenses), and (3) the Indemnifying Party will remain responsible for any
      Adverse Consequences the Indemnified Party may suffer resulting from,
      arising out of, relating to, in the nature of, or caused by the Third
      Party Claim to the fullest extent provided in this Section 8.

      (e)   CLAIMS FOR INDEMNIFICATION.

            (i) Whenever any claim shall arise for indemnification under Section
      8(b) or 8(c), the Indemnified Party shall describe such claim in a written
      notice ("Notice of Claim") to the Indemnifying Party (and for purposes of
      this Section 9(e), a notice given pursuant to Section 9(d) shall
      constitute a "Notice of Claim") and, when known, specify the facts
      constituting the basis for such claim and the amount or an estimate of the
      amount of such claim.

            (ii) Following the receipt by the Indemnifying Party of each Notice
      of Claim, the Indemnifying Party may give the Indemnified Party written
      notice ("Notice of Objection") (1) attaching a copy of such Notice of
      Claim, (2) stating that, in the opinion of the Indemnifying Party, the
      claim described in such Notice of Claim is invalid (either in whole or in
      specified part), (3) giving the reasons for the alleged invalidity, and
      (4) stating that, based on such alleged invalidity, the Indemnifying Party
      objects to the payment of any portion of the amount claimed pursuant to
      such Notice of Claim. If a Notice of Objection alleges that

                                     25
<PAGE>   29
      a Notice of Claim is only partially invalid, the Indemnifying Party within
      30 days of the receipt of such Notice of Claim, agrees to deliver to the
      Indemnified Party that portion of the amount claimed pursuant to such
      Notice of Claim as to which no objection is made.

      (f) DETERMINATION OF ADVERSE CONSEQUENCES. There shall be taken into
account the time cost of money (using the Applicable Rate as the discount rate)
and appropriate adjustments shall be made for tax consequences and insurance in
determining Adverse Consequences for purposes of this Section 8.

      (g) OTHER INDEMNIFICATION PROVISIONS. The foregoing indemnification
provisions are in addition to, and not in derogation of, any statutory,
equitable, or common law remedy any Party may have for breach of this Agreement.

stock so surrendered shall have been converted as aforesaid, in such

a certificate or certificates representing the 2,000 shares comprising the

contemplated by this Agreement will, in fact, constitute such a reorganization.

      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 Shares or an available exemption from registration
      under the Securities Act, the Shares must be held indefinitely.

            (e) Each of Netco Acquisition, TWG, MCM and ADV agrees that the
      Shares shall bear legends in substantially the following form:

the other of any material adverse development causing a breach of or
constituting an intervening event with respect to any of its own representations

or other arrangement for the benefit or welfare of any employee, director or

contained in this Agreement becoming unperformable. Pending the Closing,
EqualNet will promptly advise Netco Acquisition and Netco of any action or event
of which it becomes aware which has the effect of making incorrect any of such
representations or warranties or which has the effect of rendering unperformable
any of such covenants.

      (i) VALID ISSUANCE. EqualNet covenants that the Shares to be issued by
EqualNet pursuant to Section 2(b) will, upon the effectiveness of the Merger in

<PAGE>   26
      (j) GOVERNMENT REGULATIONS. EqualNet covenants that it will comply, and
will cause each of its Subsidiaries to comply, with all applicable governmental
restrictions and regulations, the failure to comply with which would have a
material adverse effect on the business or financial condition of EqualNet and

licenses, permits and approvals from any and all governments, governmental
commissions, boards or agencies of jurisdictions in which it or any of its
Subsidiaries carries on business required in respect of the operations of
EqualNet or any of its Subsidiaries, the failure to comply with which would have
a Material Adverse Effect.

      (k) ERISA. Promptly (and in any event within 30 days) after EqualNet or
any of its Subsidiaries knows or has reason to know that a Reportable Event with
respect to any Pension Plan has occurred, that any Pension Plan is or may be
terminated, reorganized, partitioned or declared insolvent under Title IV of
ERISA or that EqualNet or any of its Subsidiaries will or may incur any
liability to or on account of a Pension Plan under Sections 4062, 4063, 4064,
4201 or 4204 of ERISA, EqualNet will deliver to Netco Acquisition and Netco a
certificate of the chief financial officer of EqualNet setting forth information
as to such occurrence and what action, if any, EqualNet is required or proposes

EqualNet or any of its Subsidiaries. Each annual report and any notice required
to be delivered hereunder shall be delivered no later than 10 days after the
later of the date such report or notice is filed with the Internal Revenue

any of its Subsidiaries, as the case may be.

      (l) CORPORATE EXISTENCE; MAINTENANCE OF PROPERTIES. EqualNet covenants
that it (i) will do or cause to be done all things reasonably necessary to

rights of EqualNet and all of its Subsidiaries, (ii) will cause its properties
and the properties of its Subsidiaries used or useful in the conduct of their
respective businesses to be maintained and kept in good condition, repair and
working order and will use commercially reasonable efforts to cause to be made
all necessary repairs, renewals, replacements, betterments and improvements
thereto, and (iii) will, and will cause each of its Subsidiaries to, qualify and
remain qualified to conduct business in each jurisdiction where the nature of
the business or the ownership of property by EqualNet or such Subsidiary may
require such qualification and where the failure to so qualify would have a
Material Adverse Effect.

      (m) INSURANCE. EqualNet covenants that it will maintain, and will cause
each of its Subsidiaries to maintain, with financially sound and reputable
insurance companies, funds or underwriters, insurance for EqualNet and its
Subsidiaries of the kinds, covering the risks and in the relative proportionate
amounts usually carried by companies conducting business activities similar to
those of EqualNet and its Subsidiaries.

      (n) FURTHER ASSURANCES. EqualNet covenants that it shall cooperate with

this Agreement.

      (o) NOTICES OF CERTAIN EVENTS. EqualNet shall promptly give notice to
Netco Acquisition and Netco (i) of any default or event of default that has not
been cured within any applicable grace period under any (y) Indebtedness of
EqualNet or any of its Subsidiaries, or (z) contractual obligation of EqualNet
or any of its Subsidiaries or (ii) of any pending or threatened litigation,
investigation or proceeding to which EqualNet or any of its Subsidiaries is or
is threatened to be a party and of which EqualNet has been given notice;
provided that any such default as specified in clause (z) above, litigation,
investigation or proceeding would have a Material Adverse Effect. Any notice
delivered pursuant to this Section 5(o) shall be accompanied by an officer's
certificate specifying the details of the occurrence referred to therein and
stating what action EqualNet proposes to take with respect thereto.

      (p) BOARD NOMINEES. Effective as of the Closing, in addition to the
covenant in Section 5.J of the Stock Purchase Agreement, the directors of
EqualNet shall elect one new director who shall have been nominated by MCM
Partners, a Washington limited partnership, subject to the directors of EqualNet
approving the individual so nominated by MCM Partners, and if such approval is
not given, then MCM Partners shall have the right to nominate additional
individuals to serve as such director until such approval is obtained.
EqualNet's board of directors shall not unreasonably withhold or delay the
approval of the individual(s) so nominated by MCM Partners. Such director shall
serve a term expiring at the next shareholders meeting of EqualNet applicable to
the class to which such director is elected.

      (q) ENVIRONMENTAL LAWS. EqualNet and its Subsidiaries shall comply with
all applicable Environmental Laws the failure to comply with which would have a
Material Adverse Effect. If EqualNet or any Subsidiary shall receive written
notice that there exists a violation of Environmental Law with respect to its
operations or any real property owned, formerly owned, used, or leased thereby,
which violation could have a Material Adverse Effect, EqualNet shall immediately
notify in writing Netco Acquisition and Netco. Furthermore, if EqualNet or any
Subsidiary shall receive written notice that there exists a violation of
Environmental Law with respect to its operations or any real property owned,
formerly owned, used or leased thereby, which violation could have a Material
Adverse Effect, EqualNet shall within the time period permitted by the
applicable governmental authority (unless otherwise contested by EqualNet in
good faith) remove or remedy such violation in accordance with all applicable
Environmental Laws unless the Board of Directors of EqualNet makes a good faith
determination that it would be in the best interest of EqualNet to delay the
remedy of such violation, so long as no Material Adverse Effect is suffered by
EqualNet or its Subsidiaries during such delay.

      (r) REGISTRATION RIGHTS. At the Closing EqualNet will grant to MCM and ADV
certain registration rights pursuant to the Registration Agreement.

      (s)   SHAREHOLDER APPROVAL; PREPARATION OF PROXY STATEMENTS.

            (i) EqualNet shall, as soon as practicable following the execution
      and delivery of this Agreement duly call, give notice of, convene and hold
      a meeting of EqualNet's shareholders (the "Shareholders Meeting") for the
      following purposes: (i) approving this Agreement, the issuance of the
      Shares and the transactions contemplated hereby, (ii) ratifying the Note
      and Warrant Purchase Agreement and the transactions contemplated thereby,
      (iii) approving the Stock Purchase Agreement and the issuance of EqualNet
      Common Shares thereunder, (iv) approving the Switch Agreement, (v)
      approving an amendment to the Company's Articles of Incorporation to
      increase the aggregate number of authorized EqualNet Common Shares to
      55,000,000, and (vi) approving the other related transactions. EqualNet
      will, through its officers and its Board of Directors, unanimously
      recommend to its shareholders the approval and adoption of the foregoing
      transactions.

            (ii) Promptly following the date of this Agreement, EqualNet shall
      prepare and file with the Commission a proxy statement relating to the
      Shareholders Meeting (such proxy statement as amended or supplemented from
      time to time, the "Proxy Statement"). Netco Acquisition and Netco shall
      have the right to review and approve the Proxy Statement prior to EqualNet
      filing the Proxy Statement with the Commission, which approval shall not
      be unreasonably withheld. EqualNet will use commercially reasonable
      efforts to cause the Proxy Statement to be mailed to EqualNet's
      shareholders as promptly as practicable. EqualNet will notify Netco
      Acquisition and Netco promptly of the receipt of any written or oral
      comments from the Commission or its staff and of any request by the
      Commission or its staff for amendments or supplements to the Proxy
      Statement or for additional information and will supply Netco Acquisition
      and Netco with copies of all correspondence between EqualNet or any of its
      representatives, on the one hand, and the Commission or its staff, on the
      other hand, with respect to the Proxy Statement.

            (iii) EqualNet will cause its transfer agent to make stock transfer
      records relating to EqualNet available to the extent reasonably necessary
      to effectuate the intent of this Agreement.

      (t) NO SOLICITATION. (i) EqualNet shall not, nor shall it permit any of
its Subsidiaries to, nor shall it authorize or permit any officer, director or
employee of EqualNet or any investment banker, attorney or other advisor, agent
or representative of EqualNet or any of its Subsidiaries to, directly or
indirectly, (1) solicit, initiate or encourage the submission of any takeover
proposal, (2) enter into any agreement (other than confidentiality and
standstill agreements in accordance with the immediately following proviso) with
respect to any takeover proposal, or (3) participate in any discussions or
negotiations regarding, or furnish to any Person any information with respect
to, or take any other action to facilitate any inquiries or the making of any
proposal that constitutes, or may be reasonably be expected to lead to, any
takeover proposal; provided, in the case of this clause (3), that prior to the
vote of shareholders of EqualNet for approval of the matters referred to in
Section 5(s) (and not thereafter if such matters are approved thereby) to the
extent required by the fiduciary obligations

                                     -24-
<PAGE>   29
of the Board of Directors of EqualNet, determined in good faith by a majority of
the disinterested members thereof based on the advice of outside counsel,
EqualNet, in response to an unsolicited superior proposal and a request for
information pursuant thereto, may furnish information to any person or "group"
within the meaning of Section 13(d)(3) of the Exchange Act pursuant to a
confidentiality agreement. Without limiting the foregoing, it is understood that
any violation of the restrictions set forth in the preceding sentence by any
officer, director or employee of EqualNet or any of its Subsidiaries or any
investment banker, attorney or other advisor, agent or representative of
EqualNet, whether or not such Person is purporting to act on behalf of EqualNet
or otherwise, shall be deemed to be a material breach of this Agreement by
EqualNet. For purposes of this Section 5(t), "takeover proposal" means (x) any
proposal, other than a proposal by TWG or any of its Affiliates, for a merger or
other business combination involving EqualNet, (y) any proposal or offer, other
than a proposal or offer by TWG or any of its Affiliates, to acquire from
EqualNet or any of its Affiliates in any manner, directly or indirectly, an
equity interest in EqualNet or any Subsidiary, any voting securities of EqualNet
or any Subsidiary or a material amount of the assets of EqualNet and its
Subsidiaries, taken as a whole, or (z) any proposal or offer, other than a
proposal or offer by TWG or any of its Affiliates, to acquire from the
shareholders of EqualNet by tender offer, exchange offer or otherwise more than
20% of the outstanding shares of Common Shares.

            (ii) Neither the Board of Directors of EqualNet nor any committee
thereof shall, except in connection with the termination of this Agreement
pursuant to Section 7, (1) withdraw or modify, or propose to withdraw or modify,
in a manner adverse to Netco Acquisition or Netco the approval or recommendation
by the Board of Directors of EqualNet or any such committee thereof of this
Agreement or take any action having such effect; provided, a statement by the
Board of Directors of EqualNet to its shareholders as contemplated by Rule
14e-2(a) of the Exchange Act following Netco Acquisition's and Netco's receipt
of a Notice of Superior Proposal (defined below) shall not be deemed to
constitute a withdrawal or modification of its recommendation of this Agreement,
or (2) approve or recommend, or propose to approve or recommend, any takeover
proposal. Notwithstanding the foregoing, in the event that the Board of
Directors of EqualNet receives a takeover proposal that, in the exercise of its
fiduciary obligations (as determined in good faith by a majority of the
disinterested members thereof based on the advice of outside counsel), it
determines to be a superior proposal, the Board of Directors of EqualNet may
withdraw or modify its approval or recommendation of this Agreement and may
(subject to the following sentence) terminate this Agreement, in each case at
any time after midnight on the fifth Business Day following Netco Acquisition's
and Netco's receipt of written notice (a "Notice of Superior Proposal") advising
Netco Acquisition and Netco that the Board of Directors of EqualNet has received
a takeover proposal that it has determined to be a superior proposal, specifying
the material terms and conditions of such superior proposal (including the
proposed financing for such proposal and a copy of any documents conveying such
proposal) and identifying the Person making such superior proposal. EqualNet may
terminate this Agreement pursuant to the preceding sentence only if the
shareholders of EqualNet have not yet voted upon the matters set forth in
Section 5(s). Any of the foregoing to the contrary notwithstanding, EqualNet may
engage in discussions with any Person or group that has made an unsolicited
takeover proposal for the limited purpose of determining whether such proposal
is a superior

                                    -25-
<PAGE>   30
proposal. Nothing contained herein shall prohibit EqualNet from taking and
disclosing to its shareholders a position contemplated by Rule 14e-2(a)
following Netco Acquisition and Netco's receipt of a Notice of Superior
Proposal.

            (iii) For purposes of this Section 5(t), a "superior proposal" means
any BONA FIDE takeover proposal to acquire, directly or indirectly, for
consideration consisting of cash, securities or a combination thereof, all of
the EqualNet Common Shares then outstanding or all or substantially all of the
assets of EqualNet and its Subsidiaries, and otherwise on terms that a majority
of the disinterested members of the Board of Directors of EqualNet determines in
its good faith reasonable judgment (based on the advice of a financial advisor
of nationally recognized reputation, a copy of which shall be provided to Netco
Acquisition and Netco) to be more favorable to EqualNet's shareholders than the
transactions contemplated by this Agreement, the Stock Purchase Agreement and
the Switch Agreement.

            (iv) In addition to the obligations of EqualNet set forth in clause
(ii) above, EqualNet shall promptly advise Netco Acquisition and Netco orally
and in writing of any takeover proposal or any inquiry with respect to or which
could lead to any takeover proposal, the material terms and conditions of such
inquiry or takeover proposal (including the financing for such proposal and a
copy of such documents conveying such proposal), and the identity of the Person
making any such takeover proposal or inquiry.

      (u) LISTING OF COMMON STOCK. EqualNet warrants to and agrees with Netco
Acquisition that it will use commercially reasonable efforts to cause the
EqualNet Common Shares to be issued pursuant to the Merger or upon conversion of

      (b) INDEMNIFICATION PROVISIONS FOR BENEFIT OF NETCO ACQUISITION, ITS

      (d)   MATTERS INVOLVING THIRD PARTIES.

            (i) If any third party shall notify any Party (the "Indemnified
      Party") with respect to any matter (a "Third Party Claim") that may give
      rise to a claim for indemnification against any other Party (the
      "Indemnifying Party") under this Section 8, then the Indemnified Party
      shall promptly notify the Indemnifying Party thereof in writing; provided,
      no delay on the part of the Indemnified Party in notifying the
      Indemnifying Party shall relieve the Indemnifying Party from any
      obligation hereunder unless (and then solely to the extent) the
      Indemnifying Party thereby is prejudiced.

            (ii) The Indemnifying Party will have the right to defend the
      Indemnified Party against the Third Party Claim with counsel of the
      former's choice reasonably satisfactory to the Indemnified Party so long
      as (1) the Indemnifying Party notifies the Indemnified Party in writing
      within 15 days after the Indemnified Party has give notice of the Third
      Party Claim that the Indemnifying Party will indemnify the Indemnified
      Party from and against the entirety of any Adverse Consequences the
      Indemnified Party may suffer resulting from, arising out of, relating to,
      in the nature of, or caused by the Third Party Claim, (2) the Indemnifying
      Party provides the Indemnified Party with evidence reasonably acceptable
      to the Indemnified Party that the Indemnifying Party will have the
      financial resources to defend against the Third Party Claim and fulfill
      its indemnification obligations hereunder, (3) the Third Party Claim
      involves only money damages and does not seek an injunction or other
      equitable relief, (4) settlement of, or an adverse judgment with respect
      to, the Third Party Claim is not in the good faith judgment of the
      Indemnified Party, likely to establish a

                                    -31-
<PAGE>   36
      precedential custom or practice materially adverse to the continuing
      business interests of the Indemnified Party, and (5) the Indemnifying
      Party conducts the defense of the Third Party Claim actively and
      diligently.

            (iii) So long as the Indemnifying Party is conducting the defense of
      the Third Party Claim in accordance with Section 8(d)(ii), (1) the
      Indemnified Party may retain separate co-counsel at its sole cost and
      expense and participate in the defense of the Third Party Claim, (2) the
      Indemnified Party will not consent to the entry of any judgment or enter
      into any settlement with respect to the Third Party Claim without the
      prior written consent of the Indemnifying Party (not to be withheld
      unreasonably), and (3) the Indemnifying Party will not consent to the
      entry of any judgment or enter into any settlement with respect to the
      Third Party Claim without the prior written consent of the Indemnified
      Party (not to be withheld unreasonably).

            (iv) In the event any of the conditions in Section 8(d)(ii) is or
      becomes unsatisfied, however, (1) the Indemnified Party may defend
      against, and consent to the entry of any judgment or enter into any
      settlement with respect to, the Third Party Claim in any manner it
      reasonably may deem appropriate (and the Indemnified Party need not
      consult with, or obtain any consent from, the Indemnifying Party in
      connection therewith), (2) the Indemnifying Party will reimburse the
      Indemnified Party promptly and periodically for the costs of defending
      against the Third Party Claim (including reasonable attorneys' fees and
      expenses), and (3) the Indemnifying Party will remain responsible for any
      Adverse Consequences the Indemnified Party may suffer resulting from,
      arising out of, relating to, in the nature of, or caused by the Third
      Party Claim to the fullest extent provided in this Section 8.

      (e)   CLAIMS FOR INDEMNIFICATION.

            (i) Whenever any claim shall arise for indemnification under Section
      8(b) or 8(c), the Indemnified Party shall describe such claim in a written
      notice ("Notice of Claim") to the Indemnifying Party (and for purposes of
      this Section 9(e), a notice given pursuant to Section 9(d) shall
      constitute a "Notice of Claim") and, when known, specify the facts
      constituting the basis for such claim and the amount or an estimate of the
      amount of such claim.

            (ii) Following the receipt by the Indemnifying Party of each Notice
      of Claim, the Indemnifying Party may give the Indemnified Party written
      notice ("Notice of Objection") (1) attaching a copy of such Notice of
      Claim, (2) stating that, in the opinion of the Indemnifying Party, the
      claim described in such Notice of Claim is invalid (either in whole or in
      specified part), (3) giving the reasons for the alleged invalidity, and
      (4) stating that, based on such alleged invalidity, the Indemnifying Party
      objects to the payment of any portion of the amount claimed pursuant to
      such Notice of Claim. If a Notice of Objection alleges that a Notice of
      Claim is only partially invalid, the Indemnifying Party within 30 days of
      the receipt of such Notice of Claim, agrees to deliver to the Indemnified
      Party that portion of the amount claimed pursuant to such Notice of Claim
      as to which no objection is made.

                                    -32-
<PAGE>   37
      (f) DETERMINATION OF ADVERSE CONSEQUENCES. There shall be taken into
account the time cost of money (using the Applicable Rate as the discount rate)
and appropriate adjustments shall be made for tax consequences and insurance in
determining Adverse Consequences for purposes of this Section 8.

      (g) OTHER INDEMNIFICATION PROVISIONS. The foregoing indemnification
provisions are in addition to, and not in derogation of, any statutory,
equitable, or common law remedy any Party may have for breach of this Agreement.

9.    MISCELLANEOUS.

        adoption of the foregoing transactions.

                (b) Promptly following the date of this Agreement, the Company
        shall prepare and file with the Commission a proxy statement relating to
        the Shareholders Meeting (such proxy statement as amended or
        supplemented from time to time, the "Proxy Statement"). The Purchaser
        shall have the right to review and approve the Proxy Statement prior to
        the Company filing the Proxy Statement with the Commission which
        approval shall not be unreasonably withheld. The Company will use all
        commercially reasonable efforts to cause the Proxy Statement to be
        mailed to the Company's shareholders as promptly as practicable. The
        Company will notify the Purchaser promptly of the receipt of any written
        or oral comments from the Commission or its staff and of any request by
        the Commission or its staff for amendments or supplements to the Proxy
        Statement or for additional information and will supply the Purchaser
        with copies of all correspondence between the Company or any of its
        representatives, on the one hand, and the Commission or its staff, on
        the other hand, with respect to the Proxy Statement.

                (c) The Company will cause its transfer agent to make stock
        transfer records relating to the Company available to the extent
        reasonably necessary to effectuate the intent of this Agreement.

        5N. NO SOLICITATION. (a) The Company shall not, nor shall it permit any
of its Subsidiaries to, nor shall it authorize or permit any officer, director
or employee of the Company or any investment banker, attorney or other advisor,
agent or representative of the Company or any of its Subsidiaries to, directly
or indirectly, (i) solicit, initiate or encourage the submission of any takeover

                                       13

proposal, (ii) enter into any agreement (other than confidentiality and
standstill agreements in accordance with the immediately following proviso) with
respect to any takeover proposal, or (iii) participate in any discussions or
negotiations regarding, or furnish to any Person any information with respect
to, or take any other action to facilitate any inquiries or the making of any
proposal that constitutes, or may be reasonably be expected to lead to, any
takeover proposal; PROVIDED, HOWEVER, in the case of this clause (iii), that
prior to the vote of shareholders of the Company for approval of the matters
referred to in Paragraph 5M hereof (and not thereafter if such matters are
approved thereby) to the extent required by the fiduciary obligations of the
Board of Directors of the Company, determined in good faith by a majority of the
disinterested members thereof based on the advice of outside counsel, the
Company, in response to an unsolicited superior proposal and a request for
information pursuant thereto, may furnish information to any person or "group"
within the meaning of Section 13(d)(3) of the Exchange Act pursuant to a
confidentiality agreement. Without limiting the foregoing, it is understood that
any violation of the restrictions set forth in the preceding sentence by any
officer, director or employee of the Company or any of its Subsidiaries or any
investment banker, attorney or other advisor, agent or representative of the
Company, whether or not such Person is purporting to act on behalf of the
Company or otherwise, shall be deemed to be a material breach of this Agreement
by the Company. For purposes of this Paragraph 5M, "takeover proposal" means (i)
any proposal, other than a proposal by the Purchaser or any of its Affiliates,
for a merger or other business combination involving the Company, (ii) any
proposal or offer, other than a proposal or offer by the Purchaser or any of its
Affiliates, to acquire from the Company or any of its Affiliates in any manner,
directly or indirectly, an equity interest in the Company or any Subsidiary, any
voting securities of the Company or any Subsidiary or a material amount of the
assets of the Company and its Subsidiaries, taken as a whole, or (iii) any
proposal or offer, other than a proposal or offer by the Purchaser or any of its
Affiliates, to acquire from the shareholders of the Company by tender offer,
exchange offer or otherwise more than 20% of the outstanding shares of Common
Stock.

        (b) Neither the Board of Directors of the Company nor any committee
thereof shall, except in connection with the termination of this Agreement
pursuant to Paragraph 8A, (i) withdraw or modify, or propose to withdraw or
modify, in a manner adverse to the Purchaser the approval or recommendation by
the Board of Directors of the Company or any such committee thereof of this
Agreement or take any action having such effect; PROVIDED, HOWEVER, that a
statement by the Board of Directors of the Company to its shareholders as
contemplated by Rule 14e-2(a) of the Exchange Act following Purchaser's receipt
of a Notice of Superior Proposal (defined below) shall not be deemed to
constitute a withdrawal or modification of its recommendation of this Agreement,
or (ii) approve or recommend, or propose to approve or recommend, any takeover
proposal. Notwithstanding the foregoing, in the event that the Board of
Directors of the Company receives a takeover proposal that, in the exercise of
its fiduciary obligations (as determined in good faith by a majority of the
disinterested members thereof based on the advice of outside counsel), it
determines to be a superior proposal, the Board of Directors of the Company may
withdraw or modify its approval or recommendation of this Agreement and may
(subject to the following sentence) terminate this Agreement, in each case at
any time after midnight on the fifth Business Day following Purchaser's receipt
of written notice (a "Notice of Superior Proposal") advising Purchaser that the
Board of Directors of the Company has received a takeover proposal that it has
determined to be a superior proposal, specifying the material terms and
conditions of such superior proposal (including the proposed financing for such
proposal and a copy of any documents conveying such proposal) and identifying
the person making such superior proposal. The Company may terminate this
Agreement

                                       14
<PAGE>   19
pursuant to the preceding sentence only if the shareholders of the Company have
not yet voted upon the matters set forth in Paragraph 5M hereof. Any of the
foregoing to the contrary notwithstanding, the Company may engage in discussions
with any Person or group that has made an unsolicited takeover proposal for the
limited purpose of determining whether such proposal is a superior proposal.
Nothing contained herein shall prohibit the Company from taking and disclosing
to its shareholders a position contemplated by Rule 14e-2(a) following
Purchaser's receipt of a Notice of Superior Proposal.

        (c) For purposes of this Paragraph 5N, a "superior proposal" means any
BONA FIDE takeover proposal to acquire, directly or indirectly, for
consideration consisting of cash, securities or a combination thereof, all of
the shares of Common Stock then outstanding or all or substantially all of the
assets of the Company and its Subsidiaries, and otherwise on terms that a
majority of the disinterested members of the Board of Directors of the Company
determines in its good faith reasonable judgment (based on the advice of a
financial advisor of nationally recognized reputation, a copy of which shall be
provided to Purchaser) to be more favorable to the Company's shareholders than
the transactions contemplated by this Agreement, the Network Agreement and Plan
of Reorganization and the Switch Agreement.

        (d) In addition to the obligations of the Company set forth in paragraph
(b), the Company shall promptly advise the Purchaser orally and in writing of
any takeover proposal or any inquiry with respect to or which could lead to any
takeover proposal, the material terms and conditions of such inquiry or takeover
proposal (including the financing for such proposal and a copy of such documents
conveying such proposal), and the identity of the Person making any such
takeover proposal or inquiry.

Adverse Effect), or (c) violate any law, judgment, order, writ, injunction,

        to use, free and clear of all liens, claims, and restrictions, all
        patents, trademarks, service marks, trade names, and copyrights, and all
        applications, licenses, and rights with respect to the foregoing, and
        all trade secrets, including know-how, inventions, designs, processes,
        works of authorship, computer programs, and technical data and
        information (collectively, "INTELLECTUAL PROPERTY") used and sufficient
        for use in the conduct of its business as now conducted and/or as
        presently proposed to be conducted (including, without limitation, the
        development, manufacture, operation, and sale of all products and
        services sold or proposed to be sold by the Company and its Subsidiaries
        during the next 24 months following the date of this Agreement) without

        and its Subsidiaries while in the employ of the Company and its
        Subsidiaries shall be the property solely of the Company and its
        Subsidiaries. The Company and its Subsidiaries have taken security
        measures to protect the secrecy, confidentiality, and value of all
        Intellectual Property, which measures are reasonable and customary in
        the industry in which the Company and its Subsidiaries operate. The
        Company and its Subsidiaries' employees and other persons who, either
        alone or in concert with others, developed, invented, discovered,

        information about the Intellectual Property, have entered into a written
        agreement with the Company or its Subsidiaries, in form and substance

        AGREEMENT") regarding ownership and treatment of the Intellectual
        Property.

                (c) Except as described in SCHEDULE 6T, none of the Company or

        as proposed would violate, any of the patents, trademarks, service
        marks, trade names, copyrights, or trade secrets or other proprietary
        rights of any other Person or entity. None of the Company's and its
        Subsidiaries' employees is obligated under any contract (including
        licenses, covenants, or commitments of any nature) or other agreement,
        or subject to any judgment, decree, or order of any court or
        administrative agency, that would interfere with the use of such
        employee's best efforts to promote the interests of the Company or its
        Subsidiaries or that would conflict with the Company's or its
        Subsidiaries' business as presently conducted and as proposed to be
        conducted. Neither the execution nor delivery of this Agreement, nor the

enter into this Agreement, Purchaser represents and warrants to the Company
that:

        7A.     PURCHASE FOR INVESTMENT.

                (a) Purchaser is acquiring the Shares for its own account and
        not with a view to the public resale or distribution of all or any part
        thereof in any transaction which would constitute a "distribution"
        within the meaning of the Securities Act. Purchaser acknowledges that it
        does not currently intend to assign its rights under this Agreement to
        any third party prior to the Closing.

                (b) Purchaser acknowledges that the Shares have not been
        registered under the Securities Act.

                (c) Purchaser is an "accredited investor" within the meaning of
        Rule 501 under Regulation D promulgated under the Securities Act, is
        experienced in evaluating investments in companies such as the Company,
        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 entire economic risk of its investment.
        Purchaser has made its own evaluation of its investment in the Common
        Stock, based upon such information as is available to it and without
        reliance upon the Company or any other person or entity, and Purchaser
        agrees that neither the Company nor any other person or entity has any
        obligation to furnish any additional information to Purchaser except as
        expressly set forth herein.

                (d) Purchaser acknowledges that the Shares may not be sold,
        transferred, pledged, hypothecated, 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
        Shares or an available exemption from registration under the Securities
        Act, the Shares must be held indefinitely.

                (e) Purchaser agrees that the Shares shall bear legends in
        substantially the following form:

                "THE SECURITIES REPRESENTED HEREBY HAVE BEEN ACQUIRED FOR
                INVESTMENT AND MAY NOT BE SOLD OR OFFERED FOR SALE OR OTHERWISE
                TRANSFERRED,

                                       21
<PAGE>   26



                EXCEPT PURSUANT TO (i) AN EFFECTIVE REGISTRATION STATEMENT UNDER
                THE SECURITIES ACT, OR (ii) AN APPLICABLE EXEMPTION FROM
                REGISTRATION UNDER THE SECURITIES ACT. ANY SALE PURSUANT TO
                CLAUSE (ii) OF THE PRECEDING SENTENCE MUST BE ACCOMPANIED BY AN
                OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY TO THE
                EFFECT THAT SUCH EXEMPTION FROM REGISTRATION IS AVAILABLE IN
                CONNECTION WITH SUCH SALE."

        7B. AUTHORIZATION; NO CONFLICT. Purchaser has all requisite power and
authority to enter into this Agreement and to carry out and perform its
obligations under the terms of this Agreement. This Agreement is a legal, valid,
and binding obligation of Purchaser. The execution, delivery, and performance of
this Agreement by Purchaser and the consummation by Purchaser of the

organizational document applicable to Purchaser.

                shall not have been consummated on or before February 1, 1998,
                unless the failure to consummate the transaction contemplated by
                this Agreement is the result of a material breach of this
                Agreement by the party seeking to terminate this Agreement; or

                      (iii) if any permanent injunction or other order of a
                court or other competent authority preventing the consummation
                of the transactions contemplated by this Agreement or the
                Network Agreement and Plan of Reorganization or Network Switches

obligation on the part of Purchaser or the Company, other than the provisions of

                (a) The Company agrees to pay Purchaser a fee in immediately
        available funds of $500,000 (the "Termination Fee") promptly upon the
        termination of the Agreement in the event this Agreement is terminated
        by the Company as permitted by Section 5N. The Termination Fee shall be

        incurred in connection with the preparation and negotiation of this
        Agreement, any other agreement or instrument to be executed and
