to qualify as a reorganization under the provisions of Section 368(a) of the

     NOW, THEREFORE, in consideration of the mutual covenants and agreements set

                                    ARTICLE I

                                   THE MERGER

      1.1 The Merger.  Subject to the terms and conditions of this Agreement, at
          ----------
the Effective Time, the Company and MergerCo shall consummate the Merger
pursuant to which (a) MergerCo shall be merged with and into the Company and the
separate corporate existence of MergerCo shall thereupon cease, (b) the Company
shall be the successor or surviving corporation in the Merger (sometimes
hereinafter referred to as the "Surviving Corporation") and shall continue to be
                                ---------------------
governed by the laws of the State of Delaware and the DGCL, and (c) the separate
corporate existence of the Company with all its rights, privileges, immunities,
powers and franchises shall continue unaffected by the Merger. Without limiting
the generality of the foregoing, and subject thereto, at the Effective Time, all
the properties, rights, privileges, powers and franchises of the Company and
MergerCo shall vest in the Surviving Corporation, and all debts, liabilities and
duties of the Company and MergerCo shall become the debts, liabilities and
duties of the Surviving Corporation. The Company shall take such steps as are
permitted under the DGCL to (i) amend the Certificate of Incorporation of the
Company (the "Company Certificate") so that the Certificate of Incorporation of
              -------------------
MergerCo, as in effect immediately prior to the Effective Time, shall be the
Certificate of Incorporation of the Surviving Corporation until thereafter
amended as provided by law and such Certificate of Incorporation, and (ii) amend
the Bylaws of the Company (the "Company Bylaws") so that the Bylaws of MergerCo,
                                --------------
as in effect immediately prior to the Effective Time, shall be the Bylaws of the
Surviving Corporation until thereafter amended as provided by law, by the
Certificate of Incorporation of the Surviving Corporation and by such Bylaws.
Notwithstanding the foregoing, the name of the Surviving Corporation shall be
"CoreComm-Voyager, Inc." and the Certificate of Incorporation and Bylaws of the
Surviving Corporation shall so provide.  The Merger shall have the effects
specified in the DGCL, including Section 259 of the DGCL.

      1.2 Effective Time.  As promptly as practicable after all of the
          --------------
conditions set forth in Article IX shall have been satisfied or, if permissible,
waived by the party entitled to the benefit of the same, MergerCo and the
Company shall duly execute and file a certificate of merger (the "Certificate of
                                                                  --------------
Merger") with the Secretary of State of the State of Delaware in accordance with
- ------
the DGCL.  The Merger shall become effective as of the time of the Certificate
of Merger has been duly filed or such other subsequent date or time as shall be

                                       2


agreed upon by the parties and set forth in the Certificate of Merger and in
accordance with the DGCL (the "Effective Time").
                               --------------

      1.3 Closing.  The closing of the Merger (the "Closing") shall take place
          -------                                   -------
at such time and on a date to be specified by the parties, which shall be no
later than the second business day after satisfaction or waiver of all of the
conditions set forth in Article IX hereof (the "Closing Date"), at the offices
                                                ------------
of Paul, Weiss, Rifkind, Wharton & Garrison, 1285 Avenue of the Americas, New
York, NY 10019, unless another date or place is agreed to by the parties hereto.

      1.4 Tax Consequences.  It is intended by all of the parties hereto that
          ----------------
the Merger will qualify both or either (i) as a reorganization within the
meaning of Section 368(a) of the Code or (ii) a transaction that, together with
the Reincorporation (as defined herein) qualifies as an exchange under the
provisions of Section 351 of the Code and which is treated for U.S. federal
income tax purposes as a transfer of Company Common Stock by the shareholders of
the Company to Parent in exchange for the Merger Consideration.  All of the
parties to this Agreement agree to report the Merger, for all purposes, in a
manner which is consistent with the preceding sentence and no party shall take
any action, or fail to take any action which action or failure to take such
action would cause the Merger to fail to qualify (i) as a reorganization within
the meaning of Section 368(a) of the Code or (ii) a transaction that, together
with the Reincorporation (as defined herein) qualifies as an exchange under the
provisions of Section 351 of the Code and which is treated for U.S. federal
income tax purposes as a transfer of Company Common Stock by the shareholders of
the Company to Parent in exchange for the Merger Consideration.  However, it is
further intended by all of the parties hereto that if the transactions with ATX
Communications Services, Inc. ("ATX") described in Section 8.11 occur, and this
                                ---
Agreement is assigned as provided in Section 11.5, then the incorporation of
ATX, the transactions with ATX described in Section 8.11, and the transactions
described in this Agreement will be treated for U.S. federal income tax purposes
as one integrated transaction qualifying as an exchange under the provisions of
Section 351 of the Code in which the shareholders of the Company transfer
Company Common Stock in exchange for ATX stock.

      2.1 Directors of the Surviving Corporation.  The directors of MergerCo

Corporation immediately after the Effective Time until their successors shall
have been duly elected or appointed and qualified or until their earlier death,
resignation or removal in accordance with the Certificate of Incorporation and
Bylaws of the Surviving Corporation.  The Company will use reasonable efforts to
cause any director who is a designee of the Company on the Board of Directors of
any Company Subsidiary to resign as of the Effective Time.

Merger and without any action on the part of the holder of any shares of Company
Common Stock or any shares of capital stock of MergerCo:

          (a) Each issued and outstanding share of Company Common Stock held by
the Company as a treasury share or held by any direct or indirect Company
Subsidiary and each issued and outstanding share of Company Common Stock owned
by Parent, MergerCo or any other direct or indirect Parent Subsidiary
immediately prior to the Effective Time, shall be canceled and retired and cease
to exist without any conversion thereof and no payment or distribution shall be
made with respect thereto.

          (b) Each share of Company Common Stock issued and outstanding
immediately prior to the Effective Time, other than those shares referred to in
Section 3.1(a), shall be canceled and shall be converted automatically into and
represent the right to receive: (i) an amount equal to $3.00, net to the holder
in cash, without any interest thereon (plus any cash in lieu of fractional
shares as described in Section 4.1(e), the "Cash Consideration") and (ii) that
                                            ------------------
number of fully paid and nonassessable shares of Parent Common Stock equal to
$14.00 divided by the Base Stock Price (as defined below) (the "Exchange Ratio")
                                                                --------------
(rounded to the nearest thousandth and subject to adjustment, as provided below,
and subject to cash in lieu of fractional shares of Parent Common Stock, if any,
pursuant to Section 4.1(e), the "Stock Consideration" and together with the Cash
                                 -------------------
Consideration, the "Merger Consideration").
                    --------------------

          (c) The Exchange Ratio shall be adjusted as follows:

               (i)  if the Average Parent Common Stock Price is greater than the
     Collar Percentage multiplied by the Base Stock Price (such product being
     the "Ceiling Stock Price"), then the Exchange Ratio shall be adjusted such
          -------------------
     that the aggregate value (based on the Average Parent Common Stock Price)
     of the Stock Consideration will be equal to the value the Stock
     Consideration would represent if the Average Parent Common Stock Price were
     equal to the Ceiling Stock Price and there were no adjustments to the
     Exchange Ratio as contemplated in this Section 3.1.  The Collar Percentage
     shall be equal to 119%, subject to the following adjustments:  If (1) the
     Closing has not occurred on or prior to July 15, 2000, (2) subsequent to
     the date of this Agreement,

                                       4


     Parent has engaged in a transaction (other than transactions contemplated
     by this Agreement or any transaction which would result in a Base
     Adjustment (as defined below)) (a "Parent Transaction") that would (x)
                                        ------------------
     require the approval of the stockholders of Parent or, (y) require Parent
     to include the information relating to such transaction in the pro forma
     financial statements (the "Pro Formas") that are required to be contained
                                ----------
     in the Registration Statement or (z) require Parent to amend or restate the
     Pro Formas in any material manner, and (3) all conditions to Closing have
     been satisfied (or waived by the party entitled to waive such condition) or
     are capable of being satisfied on such date with reasonable best efforts,
     other than the conditions set forth in Sections 9.1(a) and 9.1(d) and the
     failure of either such condition to be satisfied is the result of a Parent
     Transaction, then, commencing on the later to occur of (i) July 16, 2000
     and (ii) the first business day after which the circumstances set forth in
     clause (3) are present (such later date being the "Trigger Day") the Collar
                                                        -----------
     Percentage shall be increased as follows: 2.5 percentage points on the
     Trigger Day, and an additional five percentage points per each 31 day
     period (a "Monthly Period") (on a pro rata basis, based on the actual
                --------------
     number of elapsed days in such Monthly Period at the Closing Date)
     beginning on the sixteenth calendar day following the Trigger Day;

               (ii)  if the Average Parent Common Stock Price is equal to or
     greater than 69% of the Base Stock Price and less than 86% of the Base
     Stock Price (86% of the Base Stock Price being the "Floor Stock Price"),
                                                         -----------------
     then the Exchange Ratio shall be adjusted such that the aggregate value
     (based on the Average Parent Common Stock Price) of the Stock Consideration
     will be equal to the value the Stock Consideration would represent if the
     Average Parent Common Stock Price were equal to the Floor Stock Price and
     there were no adjustments to the Exchange Ratio as contemplated in this
     Section 3.1; and

               (iii) subject to the provisions of Section 10.1(i), if the
     Average Parent Common Stock Price is less than 69% of the Base Stock Price,
     then the Exchange Ratio will equal that number that it would be set to in
     clause (ii) above if the Average Parent Common Stock Price were equal to
     69% of the Base Stock Price.

     For purposes of this Agreement, the "Average Parent Common Stock Price"
                                          ---------------------------------
means the volume weighted average trading price of Parent Common Stock for ten
randomly selected trading days out of the twenty (20) consecutive trading days
ending with the last trading day prior to the Closing Date.  The "Base Stock
                                                                  ----------
Price" shall be equal to $47.875, subject to the following "Base Adjustments":
- -----                                                       ----------------
(i) if, after the date of this Agreement and on or prior to the Closing Date the
outstanding shares of Parent Common Stock shall be changed into a different
number of shares by reason of any reclassification, recapitalization, stock
split, reverse stock split, combination or exchange of shares, or any dividend
payable in Parent Common Stock shall be declared thereon with a record date
within such period, or any similar event shall occur, the Base Stock Price shall
be adjusted accordingly to provide to the shareholders of the Company the same
economic effect as contemplated by this Agreement absent such reclassification,
recapitalization, stock split, reverse stock split, combination, exchange,
dividend or similar event; and (ii) if, after the date of this Agreement and on
or prior to the

                                       5


Closing Date, Parent shall distribute to all holders of Parent Common Stock
shares of capital stock of Parent other than Parent Common Stock, evidences of
indebtedness or other assets (other than cash dividends out of current or
retained earnings), or shall distribute to substantially all holders of Common
Stock rights or warrants to subscribe for securities (other than those referred
to in subsection (i) above), then in each such case the Base Stock Price shall
be multiplied by a fraction of which the numerator shall be the Current Market
Price (as defined below) of the Parent Common Stock on the record date less the
then fair market value (as determined in good faith by the Board of Directors of
Parent (the "Parent Board"), whose determination shall be conclusive evidence of
             ------------
such fair market value (absent manifest error or bad faith) and described in a
board resolution) of the portion of the assets so distributed or of such
subscription rights or warrants applicable to one share of Parent Common Stock
and of which the denominator shall be the Current Market Price of the Parent
Common Stock. The "Current Market Price" shall mean the volume weighted average
                   --------------------
trading price of Parent Common Stock for the ten randomly selected trading days
out of the prior twenty (20) consecutive trading days. Parent may only effect a
distribution described under (ii) above, if such distribution does not include
operating assets that are required to maintain the current operating businesses
of CoreComm, Inc. (a subsidiary of Parent) and the distribution of such
operating assets would not have a material adverse effect on the current
operating businesses of CoreComm, Inc., other than the LMDS licenses and related
assets.

          (d) If at any time prior to Closing, either the written opinion of
counsel required to be received by the Company pursuant to Section 9.2(e) or the
written opinion required to be received by Parent pursuant to Section 9.3(g) is
not reasonably expected to be delivered in a form acceptable to the Company and
Parent because less than 80% of the value of the Merger Consideration will be
Stock Consideration (determined as of the Closing Date) and all other conditions
to Closing set forth in Article IX have been satisfied (or waived by the party
entitled to make such condition), then the Merger Consideration shall be
adjusted by increasing the Stock Consideration and decreasing the Cash
Consideration so that the Stock Consideration shall constitute 80% of the value
of the Merger Consideration (determined as of the Closing Date) provided, that,
after such adjustment, the Merger qualifies as a reorganization under the
provisions of Section 368(a)(2)(E) of the Code.

          (e) Each share of common stock, par value $.01 per share, of MergerCo
(the "MergerCo Common Stock") issued and outstanding immediately prior to the
      ---------------------
Effective Time shall be converted into one validly issued, fully paid and non-
assessable share of common stock, par value $.01 per share, of the Surviving
Corporation (the "Surviving Corporation Common Stock"), certificates for which
                  ----------------------------------
shall be issued to the stockholders of MergerCo on a pro rata basis in
accordance with their respective shares of MergerCo upon surrender to the
Surviving Corporation of such stockholders' certificates formerly representing
such shares of MergerCo Common Stock.

          (f) All shares of Company Common Stock, when converted as provided in
Section 3.1(b), shall no longer be outstanding and shall automatically be
canceled and retired and shall cease to exist, and each Certificate previously
evidencing such shares shall thereafter represent only the right to receive the
Merger Consideration and cash in lieu of fractional shares of Parent Common
Stock in accordance with Sections 3.1(b) and 4.1(e) and any

                                       6


distribution or dividend under Section 4.1(c). The holders of Certificates
previously evidencing shares of Company Common Stock outstanding immediately
prior to the Effective Time shall cease to have any rights with respect to the
Company Common Stock except as otherwise provided herein or by law and, upon the
surrender of Certificates in accordance with the provisions of Article III
hereof, shall only represent the right to receive for their shares of Company
Common Stock the Merger Consideration and cash in lieu of fractional shares of
Parent Common Stock in accordance with Sections 3.1(b) and 4.1(e) and any
distribution or dividend under Section 4.1(c) in each case without interest.

      3.2 Company Stock Options and Related Matters.
          -----------------------------------------

          (a) Each option (collectively, the "Company Options") granted under
                                              ---------------
the Company's Amended and Restated 1998 Stock Option and Incentive Plan (the

"Company Stock Option Plan"), which is outstanding (whether or not then
- --------------------------
exercisable) as of immediately prior to the Effective Time and which has not
been exercised or canceled prior thereto, shall, at the Effective Time, be
assumed by Parent, subject to the provisions of this Section 3.2 (the "Assumed
                                                                       -------
Options").  The Assumed Options shall not terminate in connection with the
- -------
Merger and shall continue to have, and be subject to, the same terms and
conditions as set forth in the Company Stock Option Plan and agreements (as in
effect immediately prior to the Effective Time) pursuant to which the Company
Options were granted, provided that (i) all references to the Company shall be
deemed to be references to Parent and all references to shares of Company Common
Stock shall be deemed to be references to shares of Parent Common Stock, (ii)
each Company Option shall be exercisable for that number of whole shares of
Parent Common Stock equal to the product of the number of shares of Company
Common Stock covered by such Company Option immediately prior to the Effective
Time multiplied by the Option Exchange Ratio (as defined below) and rounded to
the nearest whole number of shares of Parent Common Stock and (iii) the exercise
price per share of Company Common Stock under such Company Option shall be equal
to the exercise price per share of Company Common Stock under the Company Option
divided by the Option Exchange Ratio and rounded to the nearest cent.  Parent
shall (A) reserve for issuance the number of shares of Parent Common Stock that
will become issuable upon the exercise of such Assumed Options pursuant to this
Section 3.2, (B) promptly after the Effective Time issue to each holder of a
Company Option a document evidencing the assumption by Parent of the Company's
obligations with respect thereto under this Section 3.2, and (C) promptly after
the Effective Time, cause to be filed a registration statement on an appropriate
form under the Securities Act of 1933, as amended (the "Securities Act"),
                                                        --------------
relating to the Company Stock Option Plans then in effect and covering the
shares of Parent Common Stock issuable upon exercise of the Assumed Options.  As
used in this Section 3.2, "Option Exchange Ratio" means the sum of (i) the
                           ---------------------
Exchange Ratio (as it may be adjusted) and (ii) the quotient obtained by
dividing the per share Cash Consideration by the Average Parent Common Stock
Price.

          (b) The adjustments provided in this Section 3.2 with respect to any
Company Options that are "incentive stock options" as defined in Section 422 of
the Code, shall be and are intended to be effected in a manner which is
consistent with Section 424(a) of the Code.

                                       7


          (c)   The parties to this Agreement shall take all reasonable action
required to exempt under SEC Rule 16(b)-3 the treatment of options contemplated
hereby, including, if necessary or appropriate, obtaining approvals, by each
party's Board of Directors, of the type described in a pertinent SEC no-action
letter dated January 12, 1999.

                                   ARTICLE IV

                               PAYMENT OF SHARES

      4.1 Payment for Shares of Company Common Stock.
          ------------------------------------------

          (a) From and after the Effective Time, such bank or trust company
designated by Parent, and reasonably acceptable to the Company, shall act as
exchange agent (the "Exchange Agent"). At or prior to the Effective Time,
                     --------------
MergerCo shall deposit, or MergerCo shall otherwise take all steps necessary to
cause to be deposited, with the Exchange Agent the aggregate Merger
Consideration and the cash in lieu of fractional shares of Parent Common Stock
(such aggregate Merger Consideration and cash in lieu of shares of Parent Common
Stock together with any dividends or distributions with respect thereto to which
the holders of Certificates may be entitled pursuant to Section 4.1(c) being
hereinafter referred to as the "Exchange Fund") to which holders of shares of
                                -------------
Company Common Stock shall be entitled pursuant to Section 3.1.

          (b) Promptly after the Effective Time, Parent shall cause the Exchange
Agent to mail to each holder of record of a Certificate or Certificates other
than the Company, Parent, MergerCo or any Parent Subsidiary (i) a letter of
transmittal which shall specify that delivery shall be effected, and risk of
loss and title to the Certificates shall pass, only upon delivery of the
Certificates to the Exchange Agent and shall be in such form and have such other
provisions as Parent may reasonably specify and (ii) instructions for use in
effecting the surrender of the Certificates in exchange for the Merger
Consideration and cash in lieu of fractional shares of Parent Common Stock.
Upon surrender of a Certificate for cancellation to the Exchange Agent together
with such letter of transmittal, duly executed and completed in accordance with
the instructions thereto, the holder of such Certificate shall be entitled to
receive in exchange therefor (x) a certificate representing the number of whole
shares of Parent Common Stock representing the Stock Consideration to which such
holder shall be entitled, (y) a check representing the amount of the Cash
Consideration to which such holder shall be entitled and (z) a check
representing the amount of cash in lieu of fractional shares of Parent Common
Stock, if any, plus the amount of any dividends (other than stock dividends), or
distributions, if any, pursuant to paragraph (c) below, in the case of (y) and
(z), after giving effect to any required withholding tax, and the Certificate so
surrendered shall forthwith be canceled.  No interest will be paid or accrued on
the Cash Consideration or on cash payable in lieu of fractional shares or on the
dividend or distribution, if any, payable to holders of Certificates pursuant to
this Section 4.1.  In the event of a transfer of ownership of Company Common
Stock which is not registered in the transfer records of the Company, a
Certificate representing the proper number of shares of Parent Common Stock,
together with checks for the Cash Consideration to which such holder shall be
entitled and for any cash to be paid in

                                       8


lieu of fractional shares of Parent Common Stock plus, to the extent applicable,
the amount of any dividend or distribution, if any, payable pursuant to
paragraph (c) below, may be issued and paid to such a transferee if the
Certificate representing shares of such Company Common Stock is presented to the
Exchange Agent, accompanied by all documents required to evidence and effect
such transfer and to evidence that any applicable stock transfer taxes have been
paid. If any certificate for shares of Parent Common Stock is to be issued in a
name other than that in which the surrendered Certificate is registered, it
shall be a condition of such exchange that the person requesting such exchange
shall pay any transfer or other taxes required by reason of the issuance of
certificates for shares of Parent Common Stock in a name other than that of the
registered holder of the surrendered Certificate, or shall establish to the
satisfaction of Parent or the Exchange Agent that such tax has been paid or is
not applicable.

          (c) Notwithstanding any other provisions of this Agreement, no
dividends or other distributions on Parent Common Stock shall be paid with
respect to any shares of Company Common Stock represented by a Certificate until
such Certificate is surrendered for exchange as provided herein; provided,
however, that subject to the effect of applicable laws, following surrender of
any such Certificate, there shall be paid to the holder of the certificates
representing whole shares of Parent Common Stock issued in exchange therefor,
without interest, (i) at the time of such surrender, the amount of dividends or
other distributions with a record date after the Effective Time theretofore
payable with respect to such whole shares of Parent Common Stock and not paid,
less the amount of any withholding taxes which may be required thereon, and (ii)
at the appropriate payment date, the amount of dividends or other distributions
with a record date after the Effective Time but prior to surrender and a payment
date subsequent to surrender payable with respect to such whole shares of Parent
Common Stock, less the amount of any withholding taxes which may be required
thereon.

          (d) At and after the Effective Time, there shall be no transfers on
the stock transfer books of the Company of the shares of Company Common Stock
which were outstanding immediately prior to the Effective Time.  If, after the
Effective Time, Certificates are presented to the Surviving Corporation, they
shall be canceled and exchanged for the Merger Consideration and cash in lieu of
fractional shares, if any, in accordance with this Section 4.1 (plus dividends
and distributions to the extent set forth in Section 4.1(c), if any).

          (e) No certificates or scrip representing fractional shares of Parent
Common Stock shall be issued upon the surrender for exchange of Certificates,
and such fractional share interest will not entitle its owner to vote, to
receive dividends or to any other rights of a stockholder of Parent.  In lieu of
the issuance of any fractional shares of Parent Common Stock pursuant to Section
3.1(b), the Exchange Agent shall pay to each holder of shares of Company Common
Stock exchanged pursuant to the Merger who are entitled to receive a fraction of
a share of Parent Common Stock (after taking into account all Certificates
delivered by such holder) in accordance with the provisions of this Article IV,
an amount in cash equal to the product obtained by multiplying (A) the
fractional shares of Parent Common Stock to which such holder is entitled (after
taking into account all shares of Company Common Stock held at the Effective
Time) by (B) the closing price for a share of Parent Common Stock on NASDAQ on
the first business day immediately following the Effective Time.

                                       9


          (f) Any portion of the Exchange Fund (including the proceeds of any
investments thereof and any shares of Parent Common Stock) that remains
unclaimed by the former stockholders of the Company one year after the Effective
Time shall be delivered to the Surviving Corporation.  Any former stockholders
of the Company who have not theretofore complied with this Article IV shall
thereafter look only to the Surviving Corporation for payment of their Merger
Consideration and cash in lieu of fractional shares (plus dividends and
distributions to the extent set forth in Section 4.1(c), if any), as determined
pursuant to this Agreement, without any interest thereon.  None of Parent,
MergerCo, the Company, the Exchange Agent or any other person shall be liable to
any former holder of shares of Company Common Stock for any amount properly
delivered to a public official pursuant to applicable abandoned property,
escheat or similar laws.  If any Certificates shall not have been surrendered
prior to five years after the Effective Time (or immediately prior to such
earlier date on which any Merger Consideration in respect of such Certificate
would otherwise escheat to or become the property of any Governmental Entity (as
defined herein)), any amounts payable in respect of such Certificate shall, to
the extent permitted by applicable law, become the property of the Surviving
Corporation, free and clear of all claims or interests of any person previously
entitled to those amounts.  In the event any Certificate shall have been lost,
stolen or destroyed, upon the making of an affidavit of that fact by the person
claiming such Certificate to be lost, stolen or destroyed and, if required by
the Surviving Corporation, the posting by such person of a bond in such
reasonable amount as the Surviving Corporation may direct as indemnity against
any claim that may be made against it with respect to such Certificate, the
Exchange Agent or the Surviving Corporation will issue and pay in exchange for
such lost, stolen or destroyed Certificate the Merger Consideration and cash in
lieu of fractional shares (plus, to the extent applicable, dividends and
distributions payable pursuant to Section 4.1(c)) in each case without interest.

          (g) Each of the Surviving Corporation and Parent shall be entitled to
deduct and withhold from any amounts otherwise payable pursuant to this
Agreement to any holder of a Certificate such amounts as it is required to
deduct and withhold with respect to the making of such payment under the Code,
or any provisions of Law.  To the extent that amounts are so withheld by the
Surviving Corporation or Parent, as the case may be, such withheld amounts shall
be treated for purposes of this Agreement as having been paid to the holder of a
Certificate in respect to which such deduction and withholding was made by the
Surviving Corporation or Parent, as the case may be.

the business, assets, properties, results of operations or financial condition
of  the Company and the Company Subsidiaries (as defined herein) taken as a
whole (a "Company Material Adverse Effect"). The Company has all requisite
          -------------------------------

alleging that it is, in conflict with, or in default or violation of, or, with
the giving of notice or lapse of time or both, would be in conflict with, or in

effect and has not been modified, canceled, revoked, or conditioned in any
adverse manner except for such modifications, cancellations, revocations or
conditions that would not, individually or in the aggregate, reasonably be
expected to have a Company Material Adverse Effect.  None of the Communications
Permits has been sold, conveyed, pledged, assigned or transferred to any other

in the aggregate, reasonably be expected to have a Company Material Adverse
Effect. There is no action, suit, investigation or other proceeding pending or,
to the Company's knowledge, threatened against the Company which might adversely
affect the Communications Permits, or the assignment of the Communications
Permits to Parent or MergerCo that would, individually or in the aggregate,
reasonably be expected to have a Company Material Adverse Effect. No event has
occurred with respect to the Communications Permits which permits or, after
notice or lapse of time, or both, would permit revocation or termination
thereof, or would result in any impairment of the rights of the holder of the
Communications Permits or the imposition of a forfeiture against the Company or
any subsequent holder of the Communications Permits with respect to the
operation of the facilities authorized thereby that would, individually or in
the aggregate, reasonably be expected to have a Company Material Adverse Effect.

individually or in the aggregate, reasonably be expected to have a Company

                                       20


               (iii) neither the Company nor, to the knowledge of the Company,
     any other party, is in material breach or violation of, or default under,
     any such Lease, and, to the knowledge of the Company, no event has

     with lapse of time, would constitute a material breach or default by the
     Company or, to the knowledge of the Company, any other party under such
     Lease nor has any termination event or on condition occurred under the
     Leases;

               (iv)   the Company has not assigned, transferred, conveyed,

     the property subject thereto;

               (vi)   neither the Company nor any Company Subsidiary thereof has
     any ownership, financial or other interest in the landlord under any Lease;

     grant of term or other estate in or interest affecting any Real Property
     which is superior to the interest of the Company and the Company
     Subsidiaries, as tenants under the applicable Lease; and

               (ix)   except for as disclosed in Section 5.11(c) of the Company
     Disclosure Schedule or easements, rights-of-way and other non-monetary
     encumbrances of a minor nature that do not individually or in the aggregate
     (i) interfere in any material respect with, or materially increase the cost
     of, the use, occupancy or operation of the applicable parcel of Real
     Property as currently used, occupied and operated or (ii) materially reduce
     the fair market value of the applicable parcel of Real Property below the
     fair market value such parcel would have had but for such encumbrances, the
     Real Property is free and clear of all liens, pledges, mortgages, deeds of
     trust, security interests, claims, leases, licenses, charges, options,
     rights of first refusal, easements, servitudes, transfer restrictions,
     encumbrances, restrictive covenants, encroachment or other survey defect or

          (c) All of the land, buildings, structures and other improvements used
by the Company and the Company Subsidiaries in the conduct of their businesses
are included in the Real Property, except for such land, buildings, structures
and other improvements that would not, in the aggregate, reasonably be expected
to have a Company Material Adverse Effect.

          (d) Each of the POP Agreements of the Company and the Company
Subsidiaries constitute legal, valid, binding, enforceable obligation of the
Company and  will continue to be legal, valid, binding, enforceable obligation
of the Company immediately following the Closing in accordance with the terms
thereof as in effect immediately prior to the Closing, except for those the
absence of which would not in the aggregate reasonably be expected to have a
Company Material Adverse Effect.  Neither the Company nor any Company
Subsidiary, nor to the Company's knowledge, any other person, is in violation of
or in default under (nor does there exist any condition which with the passage
of time or the giving of notice would cause such a violation of or default
under) any POP Agreement to which the Company or a Company Subsidiary is a party
or by which it or any of its properties or assets is bound or affected, except
for violations or defaults that have not resulted and would not, in the
aggregate, reasonably be expected to have a Company Material Adverse Effect.

thereby, and (D) Liens for current Taxes not yet due and payable.  All of the
machinery, equipment and other tangible personal property and assets owned or
used by the Company and the Company Subsidiaries are, to the Company's

or exemption.  Each Company Benefit Plan that requires registration with a
government body has been so registered.

          (c) With respect to any Company Benefit Plan, there has been no event
in that could subject, directly or indirectly, the Company or any Affiliate or

former employee, consultant or independent contractor, (ii) reasonablely be
expected to result in any "excess parachute payment" under Section 280G of the
Code or any payment which is non-deductible under Section 162(m) of the Code.

entitle any employee or former employee to severance pay or similar payment
which payments, individually or in the aggregate, would be material to the
Company and the Company Subsidiaries.

whether absolute or contingent, direct or indirect, including any obligations
under any Company Benefit Plan, with respect to any misclassification of a
person as an independent contractor rather than as an employee or with respect
to any employees "leased" from any employer.

          (h) Neither the Company nor any Affiliate has any obligation to
provide or any direct or indirect liability, whether contingent or otherwise,
with respect to the provision of health or death benefits to or in respect of

employees.

          (a) Schedule 5.19(a) of the Company Disclosure Letter lists or
describes, and the Company has been furnished copies of all material contracts
or arrangements to which the Company or any Company Subsidiary is a party or to
which its assets, property or business is bound or subject (other than contracts
between the Company and any Company Subsidiary), which involve aggregate
payments by or to the Company or any Company Subsidiary (including, without
limitation, payments pursuant to a guaranty of any obligations of any Company
Subsidiary or third party) of $100,000 or more, whether or not made in the
ordinary course of business (the "Company Contracts").
                                  -----------------

          (b) Except for the Company Contracts or as set forth in Section
5.19(b) of the Company Disclosure Schedule, there is no Contract that is
material to the business, results of operations, assets, properties or financial
condition of the Company and the Company

                                       28


Subsidiaries taken as a whole. Each of the Company Contracts constitutes a valid
and legally binding obligation of the Company or such Company Subsidiary and, to
the knowledge of the Company, of the other parties thereto, enforceable in
accordance with its terms, and is in full force and effect, except to the extent
the failure to be so valid, binding or enforceable, has not and would not,
individually or in the aggregate, reasonably be expected to have a Company
Material Adverse Effect. Neither the Company nor any Company Subsidiary, nor to
the Company's knowledge, any other person, is in violation of or in default
under (nor does there exist any condition which with the passage of time or the
giving of notice would cause such a violation of or default under) any Contract
to which the Company or a Company Subsidiary is a party or by which it or any of
its properties or assets is bound or affected, except for violations or defaults
that have not resulted and would not, individually or in the aggregate,
reasonably be expected to have a Company Material Adverse Effect. The Company
has satisfied all volume commitment requirements under the applicable Company
Contracts to allow for the most favorable pricing structure to be provided to
the Company under such Company Contracts. Set forth in Schedule 5.19(b), the
Company Disclosure Letter is a description of any material changes to the amount
and terms of the indebtedness of the Company and the consolidated Company
Subsidiaries as described in the notes to the financial statements set forth as
incorporated by reference in the Company's Quarterly Report on Form 10-Q for the
quarter ended September 30, 1999. The aggregate amount of indebtedness of the
Company and the Company Subsidiaries which is outstanding under the Amended and
Restated Credit Agreement, dated as of July 26, 1999, among Voyager Information,
Inc., Fleet National Bank, as agent and certain lenders, is no more than
$23,750,000.

          (c) Section 5.19(c) of the Company Disclosure Schedule sets forth a
true and complete list as of February 1, 2000 of all circuit and related
agreements and any amendments, supplements or other modifications thereto except
for those circuit and related agreements that would not, individually or in the
aggregate, reasonably be expected to have a Company Material Adverse Effect.

      5.20 Certain Agreements.  Except as set forth in Section 5.20 of the
           ------------------
Company Disclosure Letter, neither the Company nor any of the Company
Subsidiaries is a party to any oral or written (i) agreement with any executive
officer or other key employee of the Company or Company Subsidiary the benefits
of which are contingent, or the terms of which are materially altered, upon the
occurrence of a transaction involving the Company of the nature contemplated by
this Agreement, or agreement with respect to any executive officer of the
Company providing any term of employment or compensation guarantee (x) extending
for a period longer than one year after the Effective Time or (y) for the

purchase plan, any of the benefits of which will be increased, or the vesting of
the benefits of which will be accelerated, by the occurrence of any of the
transactions contemplated by this Agreement or the value of any of the benefits
of which will be calculated on the basis of any of the transactions contemplated
by this Agreement.

means a customer of the Company or a Company Subsidiary who (i) is currently
connected to and receiving Internet access service from the system and (ii) is
being charged and is paying for such service. Notwithstanding the foregoing, it
shall not be deemed to be a reduction in the number of Subscribers if a
Subscriber continues to remain as a customer of the Company, even though such
Subscriber has been aggregated with one or more other Subscribers into one
account.

      5.22 Information.  None of the information to be supplied by the Company
           -----------
for inclusion or incorporation by reference in the Proxy Statement or the Form
S-4 will, in the case of the Form S-4, at the time it becomes effective and at
the Effective Time, contain any untrue statement of a material fact or omit to
state any material fact required to be stated in that Form S-4 or necessary to
make the statements in that Form S-4 not misleading, or, in the case of the
Proxy Statement or any amendments of or supplements to the Proxy Statement, at
the time of the mailing of the Proxy Statement and any amendments of or
supplements to the Proxy Statement and at the time of the Company Stockholders
Meeting, contain any untrue statement of a material fact or omit to state any
material fact required to be stated in that Proxy Statement or necessary in

         5.24 Definition of the Company's Knowledge.  As used in this Agreement,
              -------------------------------------
the phrase "to the knowledge of the Company" or any similar phrase means the
            -------------------------------
actual (and not the constructive or imputed) knowledge after due inquiry of
Christopher P. Torto, Osvaldo deFaria, Glenn R. Friedly and James Militello.

Parent Subsidiaries (as defined herein) taken as a whole (a "Parent Material
                                                             ---------------

               ----------------------
intended to be qualified under Section 401(a) of the Code has received a
favorable determination or approval letter from the IRS regarding its
qualification under such section, and neither the Parent nor any Affiliate knows
of any event that has occurred which would preclude qualified status.  With
respect each Parent Benefit Plan, there has been no material failure to comply
with any applicable provision of ERISA, the Code or any other law which would
subject the Parent or any Affiliate to liability for any damages, penalty, or
taxes that would, individually or in the aggregate, reasonably be expected to
have a Parent Material Adverse Effect.

         6.15  Definition of Parent's Knowledge.  As used in this Agreement, the
               --------------------------------
phrase "to the knowledge of Parent" or any similar phrase means the actual (and
        --------------------------
not the constructive or imputed) knowledge after due inquiry of the executive
officers of Parent.

                                   COVENANTS

         7.1  No Solicitations.
              ----------------

          (a) The Company represents and warrants that it has terminated, and
has caused its subsidiaries and affiliates, and their respective officers,
directors, employees, investment bankers, attorneys, accountants and other
advisors or representatives to terminate, any activities, discussions or
negotiations relating to, or that may be reasonably be expected to lead to, any
Acquisition Proposal (as hereinafter defined) and will promptly request the
return of all confidential information regarding the Company provided to any
third party prior to the date of this Agreement pursuant to the terms of any
confidentiality agreements. From the date hereof until the termination hereof
and except as permitted by the following provisions of this Section 7.1, the
Company shall not, and shall not authorize or permit any of its officers,
directors or employees or any investment banker, financial advisor, attorney,
accountant or other advisor or Representative retained by it to, directly or
indirectly, (i) solicit, initiate or encourage (including by way of furnishing
non-public information), or take any other action to facilitate, any inquiries
or the making of any proposal that constitutes an Acquisition Proposal or any
inquiries or making of any proposal that constitutes, or may reasonably be
expected to lead to, an Acquisition Proposal, or (ii) participate in any
activities, discussions or negotiations regarding an Acquisition Proposal;

provided, however, that subject to compliance by the Company with the provisions
- --------  -------
of Section 7.1(b), the Company Board may furnish information to, or enter into
discussions or negotiations with, any person that makes an unsolicited written
Acquisition Proposal if, and only to the extent that (A) the Company Board,
after consultation with its outside legal counsel, determines in good faith that
such action is necessary for the Company Board to comply with its fiduciary
duties to the Company's stockholders under

                                       37


applicable law, (B) such Acquisition Proposal is not subject to any financing
contingencies or is, in the good faith judgment of the Company Board after
consultation with a nationally recognized financial advisor, reasonably capable
of being financed, and is at least as likely to be consummated as is the Merger,
(C) the Company Board determines in good faith that such Acquisition Proposal,
based upon such matters as it deems relevant (including consultation with a
nationally recognized financial advisor) would, if consummated, result in a
transaction more favorable to the Company's stockholders from a financial point
of view than the Merger (any such more favorable Acquisition Proposal being
referred to herein as a "Superior Proposal"), (D) the Company receives from such
                         -----------------
person an executed confidentiality agreement in reasonably customary form and
(E) at least three (3) business days prior to taking such action, the Company
shall provide written notice to Parent to the effect that it is taking such
action.

          (b) Prior to providing any information to or entering into discussions
with any person in connection with an Acquisition Proposal by a person as set
forth in Section 7.1(a), the Company shall notify Parent orally and in writing
of any Acquisition Proposal (including, without limitation, the material terms
and conditions thereof and the identity of the person making it) or any
inquiries indicating that any person is considering making or wishes to make an
Acquisition Proposal, as promptly as practicable (but in no case later than 24
hours) after its receipt thereof, and shall provide Parent with a copy of any
written Acquisition Proposal or amendments or supplements thereto, and shall
thereafter inform Parent on a prompt basis of (x) any material changes to the
terms and conditions of such Acquisition Proposal, and shall promptly give
Parent a copy of any information delivered to such person that amends or
supplements the Acquisition Proposal and that has not previously been provided
to Parent, and (y) any request by any person for nonpublic information relating
to its or any Company Subsidiaries' properties, books or records.

          (c) The Company Board will not withdraw or modify, or propose to
withdraw or modify, in any manner adverse to Parent, its approval or
recommendation of this Agreement or the Merger except in connection with a
Superior Proposal and then only upon or after the termination of this Agreement
pursuant to Section 10.1(c) and payment to Parent of the amounts referred to in
Section 10.2(b).

          (d) Nothing contained in this Section 7.1 shall prohibit the Company
from at any time taking and disclosing to its stockholders a position
contemplated by Rule 14d-9 or Rule 14e-2 promulgated under the Exchange Act or
making any disclosure required by Rule 14a-9 promulgated under the Exchange Act
if, the Company Board determines, in its good faith reasonable judgment after
consultation with outside legal counsel, that failure to so disclose would be
inconsistent with its obligations under applicable law.

          (e) As used in this Agreement, the term "Acquisition Proposal" shall
                                                   --------------------
mean any proposed or actual (i) merger, consolidation or similar transaction
involving the Company, (ii) sale, lease, exchange, mortgage, pledge, transfer or
other disposition, directly or indirectly, by merger, consolidation, share
exchange or otherwise, of any assets of the Company or the Company Subsidiaries
representing 15% or more of the consolidated assets of

                                       38


the Company and the Company Subsidiaries, (iii) issue, sale or other disposition
by the Company of (including by way of merger, consolidation, share exchange or
any similar transaction) securities (or options, rights or warrants to purchase,
or securities convertible into, such securities) representing 15% or more of the
votes associated with the outstanding securities of the Company, (iv) tender
offer or exchange offer in which any person shall acquire beneficial ownership
(as such term is defined in Rule 13d-3 under the Exchange Act), or the right to
acquire beneficial ownership, or any "group" (as such term is defined under the
Exchange Act) shall have been formed which beneficially owns or has the right to
acquire beneficial ownership of, 15% or more of the outstanding shares of
Company Common Stock, (v) recapitalization, restructuring, liquidation,
dissolution, or other similar type of transaction with respect to the Company,
(vi) transaction which is similar in form, substance or purpose to any of the
foregoing transactions or (vii) any public announcement of a proposal or plan to
do any of the foregoing (including, without limitation, the filing of a
registration statement under the Securities Act) or any agreement to engage in
any of the foregoing; provided, however, that the term "Acquisition Proposal"
                      --------  -------
shall not include the Merger and the other Transactions.

         7.2  Conduct of Businesses.
              ---------------------

          (a) Conduct by the Company.  Prior to the Effective Time, except as
              ----------------------
specifically permitted by this Agreement, unless Parent or MergerCo has
consented in writing thereto, the Company shall cause each Company Subsidiary to

                                                   -------------
extent consistent therewith, with no less diligence and effort then would be
applied in the absence of this Agreement, will use its reasonable best efforts
to, and to cause each Company Subsidiary to, preserve intact the business
organization of the Company and each of the Company Subsidiaries, to keep
available the services of the present officers and key employees of the Company
and the Company Subsidiaries, and to preserve the good will of customers,
suppliers and all other persons having business relationships with the Company
and the Company Subsidiaries.  Without limiting the generality of the foregoing,
and except as set forth on Section 7.2(a) of the Company Disclosure Schedule,
neither the Company nor any Company Subsidiary shall (except as expressly
permitted by this Agreement or to the extent Parent or MergerCo shall otherwise
consent in writing):

        acquisition, stock acquisition or otherwise) or enter into any material

        ordinary course of business consistent with prior practice;

                  (v)    pay, discharge or satisfy any claims, liabilities or

        connection with the transactions contemplated by this Agreement;

                  (vi)   change any of the accounting principles or practices

        course of business consistent with past practice;

                  (xi)    make or authorize any capital expenditure, which

                  (xv)    take any action that would result in any of its
        representations or warranties set forth in this Agreement becoming
        untrue or cause any conditions to closing set forth in Article IX, to

        contemplated by this Agreement; or

                  (xvi)   authorize or enter into any formal or informal written

              -----------------
or as disclosed on Section 7.2(b) of Parent Disclosure Schedule, neither Parent

or to the extent the Company shall otherwise consent in writing):

                  (i)   declare, set aside or pay any dividend or other
        distribution (whether in cash, stock or property or any combination
        thereof) in respect of Parent Common Stock, except for dividends paid by
        any Parent Subsidiary to Parent or any Parent Subsidiary that is,
        directly or indirectly, wholly owned by Parent; or

                  (ii)  authorize or enter into any formal or informal written
        or other agreement or otherwise make any commitment to do any of the
        foregoing actions; provided that nothing in this Section 7.2(b) shall
        prohibit Parent from undertaking any actions contemplated by the
        definition of Base Adjustments in Section 3.1(c)(ii) prior to Closing.

         7.3  Tax-Free Treatment.  Parent, MergerCo and the Company intend that
              ------------------
the Merger will qualify as either (i) a reorganization within the meaning of
Section 368(a) of the Code or (ii) a transaction that, together with the
Reincorporation (as defined herein) qualifies as an exchange under the
provisions of Section 351 of the Code and which is treated for U.S. federal
income tax purposes as a transfer of Company Common Stock by the shareholders of
the Company to Parent in exchange for the Merger Consideration.  None of Parent,
MergerCo or the Company shall take, or fail to take, or cause to be taken or
fail to cause to be taken, any action, whether before or after the Closing,
which action or failure to take any action would cause the Merger to fail to
constitute a "reorganization" within the meaning of Section 368(a) of the Code
or a transaction that, together with the Reincorporation (as defined herein)
qualifies as an exchange under the provisions of Section 351 of the Code and
which is treated for U.S. federal income tax purposes as a transfer of Company
Common Stock by the shareholders of the Company to Parent in exchange for the
Merger Consideration.  However, it is further intended by all of the parties
hereto that if the transactions with ATX described in Section 8.11 occur, and
this Agreement is assigned as provided in Section 11.5, then the incorporation
of ATX, the transactions with ATX described in Section 8.11, and the
transactions described in this Agreement will be treated for U.S. federal income
tax purposes as one integrated transaction qualifying as an exchange under the
provisions of Section 351 of

                                       42


the Code in which the shareholders of the Company transfer Company Common Stock
in exchange for ATX stock. No party to this Agreement shall take a position on
any Tax return that is inconsistent with the intentions expressed in this
Section 7.3.


                                 ARTICLE VIII

                             ADDITIONAL AGREEMENTS

promptly as practicable to consider and vote upon the approval of the issuance
of Parent Common Stock to be issued pursuant to the Merger and (ii) the Company
will take all action necessary in accordance with applicable Law, the Company
Certificate and the Company Bylaws to convene a meeting of its stockholders as
promptly as practicable to consider and vote upon the approval of this Agreement
and the Transactions (the "Company Stockholders Meeting").  The proxy statements
                           ----------------------------
of Parent and the Company related to their respective stockholders' meeting
shall, subject to Section 7.1 hereof, contain the recommendation of Parent Board
and the Company Board, respectively, that its stockholders approve this
Agreement and the Transactions. Subject to and in accordance with applicable
Law, each of Parent and the Company shall use its reasonable best efforts to
obtain the such approval, including, without limitation, by timely mailing the
Proxy Statement (as hereinafter defined) contained in the Form S-4 to its
stockholders.  Parent and the Company shall coordinate and cooperate with each
other with respect to the timing of their respective stockholders' meetings and
shall use their reasonable best efforts to hold such meetings on the same day.

         8.2  HSR and Other Filings.
              ---------------------

          (a) Subject to the terms and conditions herein provided and to
applicable legal requirements, each of the parties hereto agrees to use its
reasonable best efforts to (i) take, or cause to be taken, all actions and to
do, or cause to be done, all things necessary, proper or advisable to consummate
and make effective as promptly as practicable the transactions contemplated by
this Agreement and (ii) to cooperate with each other in connection with the
foregoing, including the taking of such actions as are necessary to obtain any
necessary consents, licenses, approvals, orders, exemptions and authorizations
by or from any public or private third party or Governmental Entity, including,
without limitation, those consents, licenses, approvals, exemptions or
authorizations required with respect to the agreements set forth in Sections
5.6(a) and 5.6(b) of the Company Disclosure Schedule and any others that are

any Company Subsidiary is a party or by which any of their respective properties
or assets are bound, (iii) to defend all lawsuits or other legal proceedings

requested by governmental authorities. For purposes of the foregoing sentence,
the obligations of Parent and the Company to use their "reasonable best efforts"
to obtain waivers, consents and approvals to loan agreements, leases and other
contracts shall not include any obligation to agree to an adverse modification
of the terms of such documents or to prepay or incur additional obligations to
such other parties. If, at any time after the Effective Time, any further action
is necessary or desirable to carry out the purpose of this Agreement, the proper
officers and directors of Parent and the Company shall take all such necessary
action. The Company shall use its reasonable best efforts to properly record all
assignments of its Intellectual Property and make all other necessary filings
with the United States Patent and Trademark Office and the United States
Copyright Office.

          (b) Without limiting the generality of the foregoing, as promptly as
practicable, Parent and the Company each shall properly prepare and file any
other filings required under applicable Law relating to the Merger and the other
Transactions (including filings, if any, required under the HSR Act, the
Securities Act, the Exchange Act and any other applicable federal or Blue Sky
Laws, the DGCL, Bermuda Law, other applicable Law and the rules and regulations
of NASDAQ, and the Communications Act, the PUC Regulations, and the Utility Laws
(collectively, "Other Filings").  Each of Parent and the Company shall promptly
                -------------
notify the other of the receipt of any comments on, or any request for
amendments or supplements to, any Other Filings by any Governmental Entity or
official, and each of Parent and the Company shall supply the other with copies
of all correspondence between it and each of its Subsidiaries and
representatives, on the one hand, and any other appropriate governmental
official, on the other hand, with respect to any Other Filings. None of the
parties will file any such document if any of the other parties shall have
reasonably objected to the filing of such document.  No party to this Agreement
shall consent to any voluntary extension of any statutory deadline or waiting
period or to any voluntary delay of the consummation of the Merger and the other
Transactions at the behest of any Governmental Entity without the consent and
agreement of the other party to this Agreement, which consent shall not be
unreasonably withheld or delayed.  Parent and the Company hereby covenant and
agree to use their respective reasonable best efforts to secure termination of
any waiting periods under the HSR Act and obtain the approval of the Federal
Trade Commission (the "FTC") or any other Governmental Entity for the
                       ---
transactions contemplated hereby.  The Company and Parent shall keep the other
apprised of the status of matters relating to the completion of the transactions
contemplated hereby and work cooperatively in connection with obtaining any
consents from Governmental Entity, including, without limitation: (i) promptly
notifying the other of, and if in writing, furnishing the other with copies of
(or, in the case of material oral communications, advise the other orally of)
any communications from or with any Governmental Entity with respect to the
Merger or any of the other transactions contemplated by this Agreement, (ii)
permitting the other party to review and discuss in advance, and considering in
good faith the views of one another in connection with, any proposed written (or
any material proposed oral) communication with any Governmental Entity, (iii)
not participating in any meeting with any Governmental Entity unless it consults
with the other party in advance and to the extent permitted by such Governmental
Entity gives the other party the opportunity to attend and participate thereat,
(iv) furnishing the other party with copies of all correspondence, filings and
communications (and memoranda setting forth

                                       44


the substance thereof) between it and any Governmental Entity with respect to
this Agreement and the Merger, and (v) furnishing the other party with such
necessary information and reasonable assistance as such other party may
reasonably request in connection with its preparation of necessary filings or
submissions of information to any Governmental Entity. The Company and Parent
may, as each deems advisable and necessary, reasonably designate any
competitively sensitive material provided to the other under this Section as
"outside counsel only." Such materials and the information contained therein
shall be given only to the outside legal counsel of the recipient and will not
be disclosed by such outside counsel to employees, officers, or directors of the
recipient unless express permission is obtained in advance from the source of
the materials (the Company or Parent, as the case may be) or its legal counsel.

         8.3  Proxy Statement; Registration Statement.  As promptly as
              ---------------------------------------
practicable after the execution of this Agreement, Parent and the Company shall
prepare and file with the SEC under the Securities Act a registration statement
on Form S-4 (such registration statement, together with any amendments or
supplements thereto, the "Form S-4"), in connection with the registration under
                          --------
the Securities Act of the shares of Parent Common Stock to be distributed to the

          (a) In the event of any threatened or actual claim, action, proceeding
or investigation, whether civil, criminal or administrative, including, without
limitation, any such claim, action, suit, demand, proceeding or investigation in
which any person who is now, or has been at any time prior to the date hereof,
or who becomes prior to the Effective Time, a director, officer, employee,
fiduciary or agent of the Company or any of the Company Subsidiaries (the

"Indemnified Parties") is, or is threatened to be, made a party based in whole
- --------------------
or in part on, or arising in whole or in part out of, or pertaining to (i) the
fact that he is or was a director, officer, employee, fiduciary or agent of the
Company or any of the Company Subsidiaries, or is or was serving at the request
of the Company or any of the Company Subsidiaries as a director, officer,
employee, fiduciary or agent of the Company or any Company Subsidiary or (ii)

best efforts to defend against and respond thereto.  It is understood and agreed
that the Company shall indemnify and hold harmless, and after the Effective Time
the Surviving Corporation and Parent shall indemnify and hold harmless, as and
to the full extent permitted by applicable law, each Indemnified Party against
any losses, claims, damages, liabilities, costs, expenses (including attorneys'
fees and expenses), judgments, fines and amounts paid in settlement in
connection with any such threatened or actual claim, action, suit, demand,
proceeding or investigation. In the event any such Indemnified Party is or
becomes involved in any capacity in any action, proceeding or investigation for
which indemnification is to be provided under this Agreement (whether asserted
or arising before or after the Effective Time), (A) the Company, and Parent and
the

                                       47


Surviving Corporation after the Effective Time, shall promptly pay expenses in
advance of the final disposition of any claim, action, suit, demand, proceeding
or investigation to the full extent permitted by law, provided that the
Indemnified Party may not retain more than one counsel (in addition to any

will use their respective reasonable best efforts to assist in the defense of
any such matter; provided that in no event shall the Company, Parent or the
Surviving Corporation be liable for any settlement effected without its prior
written consent (which consent shall not be unreasonably withheld); and provided
further that neither Parent nor the Surviving Corporation shall have no
obligation hereunder to any Indemnified Party when and if a court of competent
jurisdiction shall ultimately determine, and such determination shall become
final and non-appealable, that indemnification of such Indemnified Party in the
manner contemplated hereby is prohibited by applicable law. Any Indemnified
Party wishing to claim indemnification under this Section 8.7, upon learning of
any such claim, action, suit, demand, proceeding or investigation, shall notify
the Company and, after the Effective Time, Parent and the Surviving Corporation,
thereof; provided that the failure to so notify shall not affect the obligations
of the Company, Parent and the Surviving Corporation except to the extent such
failure to notify materially prejudices such party.

of, and all limitations on the personal liability of, the directors, officers,
employees and agents of the Company and the Company Subsidiaries provided for in
the Company Certificate or Bylaws as in effect as of the date hereof with
respect to matters occurring prior to the Effective Time, and including the
Merger, shall continue in full force and effect for a period of not less then
six years from the Effective Time; provided, however, that all rights to
indemnification in respect of any claims (each a "Claim") asserted or made
                                                  -----
within such period shall continue until the final disposition of such Claim.
Prior to the Effective Time, the Company may purchase an extended reporting
period endorsement under the Company's existing directors' and officers'
liability insurance coverage for the Company's directors and officers in a form
and with terms acceptable to the Company, which shall provide such directors and
officers with coverage for six years following the Effective Time of not less
than the existing coverage under, and have other terms not materially less
favorable to, the insured persons than the directors' and officers' liability
insurance coverage presently maintained by the Company, so long as the cost is
less than $ 750,000, provided that, the Company agrees to cooperate in good
                     -------- ----
faith with the Parent in order to obtain the lowest premium for the above
referenced coverage.  In the event that $ 750,000 is insufficient for the above
referenced coverage, the Company may spend up to that amount to purchase such
lesser coverage as is possible.

          (c) This Section 8.7 is intended for the irrevocable benefit of, and
to grant third party rights to, the Indemnified Parties and shall be binding on
all successors and assigns of Parent, the Company and the Surviving Corporation.

contained in this Section 8.7.

successors or assigns (i) consolidates with or merges into any other person or
entity and shall not be the continuing or surviving corporation or entity of
such consolidation or merger or (ii) transfers or conveys all or substantially
all of its properties and assets to any person or entity, then, and in each such

party, issue such press release or make such public statement as may be required
by law or the applicable rules of any stock exchange if it has used its best
efforts to consult with the other party and to obtain such party's consent but

                       TERMINATION, AMENDMENT AND WAIVER

         10.1  Termination.  This Agreement may be terminated and abandoned at
               -----------
any time prior to the Effective Time, whether before or after the approval of
matters presented in connection with the Merger by the stockholders of Parent
and the Company:

               (a) by the mutual written consent of Parent and the Company.

               (b) by either of Parent or the Company:

                   (i)   if any required approval of the stockholders of Parent
        or the Company that is a condition to the obligations of Parent or the
        Company under Section 9.1 of this Agreement shall not have been obtained
        at the Company Stockholders Meeting or the special meeting of the
        Parent's stockholders to be held to consider approval of the issuance of
        Parent Common Stock to be issued in the Merger; or

                                       55


                   (ii)  if any Governmental Entity shall have issued a final
        and nonappealable Injunction (which Injunction the parties have used
        their best efforts to lift), which permanently enjoins the Merger.

          (c) by the Company, if the Company Board shall elect to terminate this
Agreement in order to recommend or approve a Superior Proposal, provided that
(i) the Company has complied with all the terms of Section 7.1 and notified
Parent in writing that it intends to terminate this Agreement in order to
recommend or approve a Superior Proposal, attaching the most current version of
such proposal to such notice, (ii) at any time after the third business day
following written notification by the Company to Parent of the Company's
intention to enter into a binding agreement with respect to such proposal, after
taking into account any modifications to the transactions contemplated by this
Agreement that Parent has then proposed in writing and not withdrawn, the
Company Board has determined that such proposal is and continues to be a
Superior Proposal and (iii) concurrently with the effectiveness of such
termination, pays to Parent the termination fee under Section 10.2(b), it being
understood on the date of the effectiveness of such termination, whether or not
prior to such effectiveness, the Company may enter into an agreement with
respect to such Superior Proposal which agreement, if entered into prior to such
effectiveness must be conditioned upon the payment of the termination fee on the
same date as provided herein.  The termination under this Section 10.1(c) shall
not be effective until the Company has made payment to Parent of the amounts
required to be paid pursuant to Section 10.2(b).

          (d) by Parent, if (i) the Company Board shall have resolved to or
shall have (A) withdrawn, modified or changed in a manner adverse to Parent its
approval or recommendation of this Agreement, (B) failed to include such
recommendation in the Proxy Statement, (C) approved or recommended any
Acquisition Proposal, (D) entered into a definitive agreement with respect to a
Superior Proposal or (E) made a public announcement of its intention to take any
of the foregoing actions or (ii) a tender offer or exchange offer for more than
15% of the outstanding shares of the Company Common Stock is commenced and the
Company Board fails to recommend against acceptance of such tender offer or
exchange offer by its stockholders (including by taking no position with respect
to the acceptance of such tender offer or exchange offer by its stockholders).

          (e) by Parent, if it is not in material breach of its obligations
under this Agreement, on or after the later of (x) October 31, 2000, or (y) 120
days following the date on which Parent last made an initial announcement that
it had entered into a definitive agreement for a Parent Transaction, if any of
the conditions provided in Sections 9.1 and 9.3 of this Agreement have not been
satisfied and have not been waived in writing by Parent prior to such date;
provided that, if the Merger has not occurred by reason of the nonsatisfaction
of the condition set forth in Section 9.1(b) hereof or the pendency of a non
final Injunction, Parent shall have used its best efforts to cause such
condition to be satisfied or have any such Injunction stayed or reversed.

          (f) by the Company, if it is not in material breach of its obligations
under this Agreement, on or after October 31, 2000, if any of the conditions
provided in

                                       56


Sections 9.1 and 9.2 of this Agreement have not been satisfied and have not been
waived by the Company; provided, however, if the Merger has not occurred by
reason of the nonsatisfaction of the condition set forth in Section 9.1(b)
hereof or the pendency of a non-final Injunction, the Company shall have used
its best efforts to cause such condition to be satisfied or have any such
Injunction stayed or reversed.

          (g) by Parent, upon a breach of any material representation, warranty,
covenant or agreement on the part of the Company set forth in this Agreement, or
if any representation or warranty of the Company shall have become untrue, in
either case such that the conditions set forth in either of Section 9.3(a) or
9.3(b) would not be satisfied (a "Terminating Company Breach"); provided,
                                  --------------------------
however, that, if such Terminating Company Breach is curable by the Company
through the exercise of its reasonable best efforts and for so long as the
Company continues to exercise such reasonable best efforts, Parent may not
terminate this Agreement under this Section 10.1(g).

          (h) by the Company, upon breach of any material representation,
warranty, covenant or agreement on the part of Parent set forth in this
Agreement, or if any representation or warranty of Parent shall have become
untrue, in either case such that the conditions set forth in either of Section
9.2(a) or 9.2(b) would not be satisfied (a "Terminating Parent Breach");
                                            -------------------------
provided, however, that, if such Terminating Parent Breach is curable by Parent
through its reasonable best efforts and for so long as Parent continues to
exercise such reasonable best efforts, the Company may not terminate this
Agreement under this Section 10.1(h); or

          (i) by the Company if (i) as of a date not more than three business
days before the expected Closing Date, the Average Parent Common Stock Price
would be less than 69% of the Base Stock Price, (ii) irrevocable notice shall
have been provided to Parent in accordance with the notice provisions hereunder
indicating the Company's intention to terminate the Agreement, and (iii) within
one business day of receipt of such notice, Parent shall not have agreed (by
unilateral notice to the Company) to increase the number of shares of Parent
Common Stock to be issued to the shareholders of the Company pursuant to the
Merger such that as of the Closing Date, the aggregate value (based on the
Average Parent Common Stock Price) of the Parent Common Stock to be received by
the shareholders of the Company will be equal to the aggregate value (based on
the Average Parent Common Stock Price) of Parent Common Stock they would have
been entitled to receive if the Average Parent Common Stock Price were equal to
the Floor Stock Price.  In the event the Company serves the notice provided for
in (ii) above, and the Parent does not agree to increase the number of shares in
accordance with (iii) above, then the termination shall become effective
immediately on the following business day.

         10.2  Effect of Termination.
               ---------------------

               (a) In the event of the termination of this Agreement pursuant to
Section 10.1 hereof, this Agreement shall forthwith become null and void and
have no effect, without any liability on the part of any party hereto or its
Representatives, affiliates, trustees,

                                       57


directors, officers or stockholders and all rights and obligations of any party
hereto shall cease except for the agreements contained in Sections 8.6, 8.8 and
11.4 and this Section 10.2 which shall survive the termination; provided,
however, that nothing contained in this Section 10.2 shall relieve any party
from liability for any fraud or willful breach of its representations or
warranties or breach of its covenants or agreements set forth in this Agreement.

               (b) In the event the Company shall have terminated this Agreement
pursuant to Section 10.1(c), or Parent shall have terminated this Agreement
pursuant to Section 10.1(d)(i), then the Company shall simultaneously with such
termination pay Parent a termination fee equal to $19.0 million (the

"Termination Amount").  In the event that Parent shall have terminated this
- -------------------
Agreement pursuant to Section 10.1(d)(ii) and either (x) the Company shall have
entered into a definitive agreement with respect to the tender or exchange offer
giving rise to such termination or (y) the person making the tender or exchange
offer giving rise to such termination shall have accepted shares for payment
pursuant to such tender or exchange offer, the Company shall pay, upon the
earlier of entering into a definitive agreement and the acceptance of shares for
payment, to the Parent a termination fee equal to the Termination Amount.

               (c) Any payment required by this Section 10.2 shall be payable by
the Company to Parent by wire transfer of immediately available funds to an
account designated by Parent.

               (d) The Company acknowledges that the agreements contained in
this Section 10.2 are an integral part of the transactions contemplated by this
Agreement, and that, without these agreements, Parent and MergerCo would not
enter into this Agreement; accordingly, if the Company fails to pay promptly the
amounts due pursuant to Section 10.2(b), and, in order to obtain such payment,
Parent commences a suit which results in a judgment against the Company for all
or a portion of such amounts, the Company shall pay to Parent's Expenses in
connection with such suit, together with interest on the amounts payable to
Parent at the prime rate of The Chase Manhattan Bank in effect on the date such
payment was required to be made.

         10.3  Amendment.  This Agreement may be amended by the parties hereto
               ---------
by an instrument in writing signed on behalf of each of the parties hereto at
any time before or after any approval hereof by the stockholders of Parent and
the Company, but in any event following authorization by Parent Board and the
Company Board; provided, however, that after any such stockholder approval, no
amendment shall be made which by law requires further approval by the
stockholders without obtaining such approval.

understandings, both written and oral, among the parties, or any of them, with
respect to the subject matter hereof, (ii) shall be binding upon and inure to
the benefits of the parties hereto and their respective successors and assigns
and is not intended to confer upon any other person (except as set forth

                                       60


below) any rights or remedies hereunder and (iii) may be executed in two or more
counterparts which together shall constitute a single agreement. Except as
provided in Section 8.7, this Agreement is not intended to confer upon any
person other than the parties to this Agreement any rights or remedies under
this Agreement. The parties hereto agree that irreparable damage would occur in
the event that any of the provisions of this Agreement were not performed in
accordance with their specific terms or were otherwise breached. It is
accordingly agreed that the parties shall be entitled to an injunction or

merging a wholly owned first-tier domestic subsidiary of ATX into the Company,
(ii) the acquisition of Parent by ATX will be consummated after the
Reincorporation of Parent, and (iii) the acquisition of Parent by ATX will be
structured so that it will be treated for U.S. federal income tax purposes as a
transfer of stock of Parent by Parent stockholders in exchange for stock issued
by ATX.

         11.6  Severability.  If any provision of this Agreement, or the
               ------------
application thereof to any person or circumstance is held invalid or
unenforceable, the remainder of this Agreement, and the application of such
provision to other persons or circumstances, shall not be affected thereby, and
to such end, the provisions of this Agreement are agreed to be severable.

         11.7  Choice of Law/Consent to Jurisdiction.  All disputes, claims or
               -------------------------------------
controversies arising out of this Agreement, or the negotiation, validity or
performance of this Agreement, or the Transactions shall be governed by and
construed in accordance with the laws of the State of Delaware without regard to
its rules of conflict of laws.  Each of Parent, MergerCo and the Company hereby
irrevocably and unconditionally consents to submit to the sole and exclusive
jurisdiction of the courts of the State of Delaware and of the United States of
America located in the State of Delaware (the "Delaware Courts") for any
                                               ---------------

validity or performance of this Agreement, or the Transactions (and agrees not
to commence any litigation relating thereto except in such courts), waives any
objection to the laying of venue of any such litigation in the Delaware Courts
and agrees not to plead or claim in any Delaware Court that such litigation
brought therein has been brought in any inconvenient forum.  Each of the parties
hereto agrees, (a) to the extent such party is not otherwise subject to service
of process in the State of Delaware, to appoint and maintain an agent in the
State of Delaware as such party's agent for acceptance of legal process, and (b)
that service of process may also be made on such party by

                                       61


prepaid certified mail with a proof of mailing receipt validated by the United
States Postal Service constituting evidence of valid service. Service made
pursuant to (a) or (b) above shall have the same legal force and effect as if
served upon such party personally within the State of Delaware. For purposes of
implementing the parties' agreement to appoint and maintain an agent for service
of process in State of Delaware, each such party does hereby appoint The
Corporation Trust Company, 1209 Orange Street, Wilmington, New Castle County,
Delaware 19801, as such agent.

                -------------
