pursuant to which Buyer will acquire the Issuer. As a condition to and in
consideration of the promises and covenants set forth in the Merger Agreement,
Buyer and Level 3 Telecom Holdings, Inc., a Delaware corporation ("LTTH"),
                                                                   ----   
entered into a Voting Agreement, dated as of June 3, 1998 (the "Voting
                                                                ------
Agreement"), pursuant to which LTTH has agreed to vote the shares of Common
Stock owned by it (i) in favor of adoption of the Merger Agreement and approval
of the transactions contemplated thereby, (ii) against any proposal for any
recapitalization, merger, sale of assets or other business combinations of or by

ITEM 4.   PURPOSE OF TRANSACTION.
          ----------------------

 ------                                                                        
Buyer. In the Merger, each issued and outstanding share of Common Stock
(excluding shares of Common Stock held by Buyer or Merger Sub or any direct or
indirect subsidiary of Buyer or Merger Sub and shares of Common Stock owned by
stockholders of the Issuer who properly exercise dissenters' rights) will be
converted into the right to receive $40.50 per share of Common Stock in cash,
subject to certain possible closing adjustments. The Merger is subject to a
number of other conditions, including, but not limited to, regulatory approval
and approval by the stockholders of the Issuer.

ITEM 5.   INTEREST IN SECURITIES OF THE ISSUER.
          ------------------------------------ 

     Buyer may be deemed to be the beneficial owner of the Shares by virtue of
the Voting Agreement. Such beneficial ownership would represent approximately
48.3% of the Common Stock issued and outstanding at June 3, 1998.

     As of June 3, 1998, Avalon LLC owns all of the outstanding equity
interests of Buyer and, as such, exercises voting control over Buyer.
Consequently, by virtue of the voting control exercised by Avalon LLC as the
controlling shareholder of Buyer, Avalon LLC may be deemed to beneficially own
the Shares. By virtue of the relationship between Avalon LLC and the Fund
described in Item 2, the Fund may be deemed to possess indirect beneficial
ownership of the Shares beneficially owned by Avalon LLC. By virtue of the
relationship between the Fund and AEI described in Item 2, AEI may be deemed to
possess indirect beneficial ownership of the Shares beneficially owned by the
Fund, and, by virtue of the relationship between the Fund, AEI and ABRY Inc.
described in Item 2, ABRY Inc. may be deemed to possess indirect beneficial
ownership of the Shares beneficially owned by the Fund.

     As of June 3, 1998, Yudkoff owns all of the outstanding equity interests of
ABRY Inc. and, as such, exercises voting control over ABRY Inc. By virtue of the
voting control exercised by Yudkoff over ABRY Inc., Yudkoff may be deemed to
possess indirect beneficial ownership of the Shares beneficially owned by ABRY
Inc.

     The filing of this Statement shall not be construed as an admission by any
of the Reporting Persons that such person is, for the purpose of Section 13(d)
or 13(g) of the Exchange Act, the beneficial owner of any securities covered by
this Statement.

     All such ownership percentages of the Common Stock reported herein are
based on the representation of the Issuer to the Reporting Persons that, as of
May 31, 1998, there were 6,896,342 

                              Page 10 of 16 Pages

A to this statement has effected any transactions in the Common Stock during the
past 60 days.

                         AGREEMENT AND PLAN OF MERGER

     AGREEMENT AND PLAN OF MERGER dated as of June 3, 1998 among Cable Michigan,
Inc., a Pennsylvania corporation (the "COMPANY"), Avalon Cable of Michigan
Holdings Inc., a Delaware corporation ("BUYER"), and Avalon Cable of Michigan
Inc., a Delaware corporation and a wholly owned subsidiary of Buyer ("MERGER
SUBSIDIARY").

     WHEREAS, as a condition to Buyer's and Merger Subsidiary's willingness to
enter into this Agreement, simultaneously with the execution of this Agreement
Buyer is entering into a Voting Agreement (the "VOTING AGREEMENT") with Level 3
Telecom Holdings Inc.("LTTH"), a stockholder of the Company;

     In consideration for the various agreements contained herein and in the
Voting Agreement, the parties hereto agree as follows:

                                   ARTICLE 1

                                  The Merger

     Section 1.0.1. The Merger.  (a) At the Effective Time, Merger Subsidiary
shall be merged (the "MERGER") with and into the Company in accordance with the
Pennsylvania Business Corporation Law (the "PENNSYLVANIA LAW"), whereupon the
separate existence of Merger Subsidiary shall cease, and the Company shall be
the surviving corporation (the "SURVIVING CORPORATION"). If Buyer and the
Company so agree, the Merger may be structured so that the Company shall be
merged with and into Merger Subsidiary with the result that Merger Subsidiary
shall be the Surviving Corporation, provided that the agreement of the Company
shall not be unreasonably withheld.

     (b)  As soon as practicable (and in any event, no later than ten business
days) after satisfaction or, to the extent permitted hereunder, waiver of all
conditions to the Merger, (i) the Company and Merger Subsidiary will file
articles of merger with the Department of State of the Commonwealth of
Pennsylvania and make all other filings or recordings required by Pennsylvania
Law in connection with the Merger. The Merger shall become effective at such
time as the articles of merger are duly filed as described in this paragraph or
at such later time as is specified in such articles of merger by agreement of
Buyer and the Company (the "EFFECTIVE TIME").

     (c)  From and after the Effective Time, the Surviving Corporation shall
possess all the rights, privileges, powers and franchises and be subject to all
of the 
<PAGE>
 
restrictions, disabilities and duties of the Company and Merger Subsidiary, all
as provided under Pennsylvania Law.

     Section 1.0.2. Conversion of Shares.  At the Effective Time by virtue of
the Merger and without any other action on the part of the Company, Merger
Subsidiary or the holder of any Shares (as defined below):

          (a)  each outstanding share (each a "SHARE") of common stock, $1.00
     par value (the "COMMON STOCK"), of the Company held by the Company as
     treasury stock or owned by Buyer or any subsidiary of Buyer immediately
     prior to the Effective Time shall be canceled, and no payment shall be made
     with respect thereto;

          (b)  each share of common stock of Merger Subsidiary outstanding
     immediately prior to the Effective Time shall be converted into and become
     one share of common stock of the Surviving Corporation with the same
     rights, powers and privileges as the shares so converted and shall
     constitute the only outstanding shares of capital stock of the Surviving
     Corporation; and

          (c)  each Share outstanding immediately prior to the Effective Time
     shall, except as otherwise provided in Section 1.02(a) or as provided in
                                                    ---- 
     Section 1.04 with respect to Shares as to which dissenters' rights have
             ----
     been exercised, be converted into the right to receive the Per Share Amount
     (as defined below) in cash, without interest (the "MERGER CONSIDERATION");
     provided that if the Merger has not been consummated by December 1, 1998,
     the Merger Consideration shall be increased at a rate per annum equal to 8%
     from and including December 1, 1998 to but excluding the date of the
     Effective Time. Such increase shall be calculated on the basis of a year of
     365 days and the actual number of days elapsed.

     As used herein, the term "Per Share Amount" means (i) if the Closing
Subscriber Number (as defined below) is equal to or less than the Maximum Target
Subscriber Number (as defined below) and equal to or greater than the Minimum
Target Subscriber Number (as defined below), $40.50; (ii if the Closing
Subscriber Number exceeds the Maximum Target Subscriber Number, $40.50 plus the
product (rounded to the nearest whole cent) of (A) the excess of the Closing
Subscriber Number over the Maximum Target Subscriber Number times (B) $.000274;
provided that the Per Share Amount will not exceed $41.00; and (iii) if the
Minimum Target Subscriber Number exceeds the Closing Subscriber Number, $40.50
minus the product (rounded to the nearest whole cent) of (A) the excess of the
Minimum Target Subscriber Number over the Closing

                                       2
<PAGE>
 
Subscriber Number times (B) $.000274. As used herein, the term "CLOSING
SUBSCRIBER NUMBER" means the number of Basic Subscribers (as defined in Section
3.22) as of the last day of the first full calendar month ending prior to the
- ----
Effective Time; provided that if the Effective Time occurs during the first five
business days of a calendar month, the Closing Subscriber Number will be the
number of Basic Subscribers as of the last day of the second full calendar month
ending prior to the Effective Time; and provided further that if the Effective
Time occurs at any time after December 8, 1998, the Closing Subscriber Number
will be the number of Basic Subscribers as of November 30, 1998. In calculating
the Closing Subscriber Number, Basic Subscribers attributable to Systems
acquired by the Company and its Subsidiaries after the date hereof will be
disregarded. As used herein, the terms "MAXIMUM TARGET SUBSCRIBER NUMBER" and
"MINIMUM TARGET SHARE NUMBER" mean the numbers set forth below (under the
applicable heading) opposite the date as of which the Closing Subscriber Number
is determined:

     The Company and Buyer will cooperate to determine the Closing Subscriber
Number as promptly as possible and in any event at least three days in advance
of the Effective Time.  In the event of a dispute that is not resolved by three
business days prior to the Effective Time, each of the Company and Buyer will
submit its view as to the proper Closing Subscriber Number to Andersen
Consulting or other person reasonably satisfactory to Buyer and the Company (the
"EXPERT"), who will, at least one business day prior to Closing, select either
the number submitted by the Company or the number submitted by Buyer as the
Closing Subscriber Number, and the determination of the Expert shall be final
and binding on the parties.  The parties will cooperate with the Expert and
provide to the Expert all necessary information for purposes hereof.

     Section 1.03.  Surrender and Payment.  (a) Prior to the Effective Time,
Buyer shall appoint an agent reasonably acceptable to the Company (the "EXCHANGE
AGENT") for the purpose of exchanging certificates representing 

                                       3
<PAGE>
 
Shares for the Merger Consideration. Buyer will deliver to the Exchange Agent at
the Effective Time the Merger Consideration to be paid in respect of the Shares.
For purposes of determining the Merger Consideration to be delivered, Buyer
shall assume that no holder of Shares will perfect his right to appraisal of his
Shares. Promptly (and in any event, within three business days) after the
Effective Time, Buyer will send, or will cause the Exchange Agent to send, to
each holder of record of Shares at the Effective Time (and make customary
arrangements for the prompt delivery to each beneficial owner of Shares at the
Effective Time) a letter of transmittal for use in such exchange (which shall
specify that the delivery shall be effected, and risk of loss and title shall
pass, only upon proper delivery of the certificates representing Shares to the
Exchange Agent). The Company shall cooperate, and shall cause its transfer agent
to cooperate, with respect thereto.

     (b)  Each holder of Shares that have been converted into a right to receive
the Merger Consideration, upon surrender to the Exchange Agent of a certificate
or certificates representing such Shares, together with a properly completed
letter of transmittal covering such Shares and such other customary documents as
may be reasonably requested by the Exchange Agent or Buyer, will be entitled to
receive the Merger Consideration payable in respect of such Shares. Until so
surrendered, each such certificate shall, after the Effective Time, represent
for all purposes, only the right to receive such Merger Consideration. The
Exchange Agent or Buyer, as the case may be, shall be entitled to deduct and
withhold from the consideration otherwise payable pursuant to this Agreement
such amounts as the Exchange Agent or Buyer are required to deduct and withhold
under the Code (as defined below), or any applicable provision of state, local
or foreign tax law, with respect to the making of any payment in respect of the
Merger Consideration hereunder.  To the extent such amounts are so withheld,
such amounts shall be treated for all purposes of this Agreement as having been
paid to the Person with respect to whom such deduction and withholding was made
by the Exchange Agent or Buyer.  No such deduction or withholding shall be made
if the relevant Person shall provide documentation reasonably satisfactory to
the Exchange Agent and Buyer establishing an exemption from withholding, and
Buyer shall take customary actions to obtain such documentation prior to such
deduction or withholding.

     (c)  If any portion of the Merger Consideration is to be paid to a Person
other than the registered holder of the Shares represented by the certificate or
certificates surrendered in exchange therefor, it shall be a condition to such
payment that the certificate or certificates so surrendered shall be properly
endorsed or otherwise be in proper form for transfer and that the Person
requesting such payment shall pay to the Exchange Agent any transfer or other
taxes required as a result of such payment to a Person other than the registered

                                       4
<PAGE>
 
holder of such Shares or establish to the satisfaction of the Exchange Agent
that such tax has been paid or is not payable. For purposes of this Agreement,
"PERSON" means an individual, a corporation, a limited liability company, a
partnership, an association, a trust or any other entity or organization,
including a government or political subdivision or any agency or instrumentality
thereof.

     (d)  After the Effective Time, there shall be no further registration of
transfers of Shares. If, after the Effective Time, certificates representing
Shares are presented to the Surviving Corporation, they shall be canceled and
exchanged for the consideration provided for, and in accordance with the
procedures set forth, in this Article 1.
                                      -
     (e)  Any portion of the Merger Consideration made available to the Exchange
Agent pursuant to Section 1.03(a) that remains unclaimed by the holders of
                          -------
Shares three months after the Effective Time shall be returned to Buyer, upon
demand, and any such holder who has not exchanged his Shares for the Merger
Consideration in accordance with this Section prior to that time shall
thereafter look only to Buyer for payment of the Merger Consideration in respect
of his Shares. Notwithstanding the foregoing, Buyer shall not be liable to any
holder of Shares for any amount paid to a public official pursuant to applicable
abandoned property laws. Any amounts remaining unclaimed by holders of Shares
two years after the Effective Time (or such earlier date immediately prior to
such time as such amounts would otherwise escheat to or become property of any
governmental entity) shall, to the extent permitted by applicable law, become
the property of Buyer free and clear of any claims or interest of any Person
previously entitled thereto.

     (f)  Any portion of the Merger Consideration made available to the Exchange
Agent pursuant to Section 1.03(a) to pay for Shares for which dissenters' rights
                          ------- 
have been perfected shall be returned to Buyer, upon demand.

     Section 1.04. Dissenting Shares.  Notwithstanding Section 1.02, Shares
                                                               ----  
outstanding immediately prior to the Effective Time and held by a holder who has
not voted in favor of the Merger or consented thereto in writing and who has
demanded payment of the fair value of such Shares in accordance with
Pennsylvania Law (and the applicable procedures set forth therein) shall not be
converted into a right to receive the Merger Consideration, unless such holder
fails to perfect or withdraws or otherwise loses his right to demand payment of
the fair value of such Shares.  If after the Effective Time such holder fails to
perfect or withdraws or loses his right to demand payment of the fair value of
such Shares, such Shares shall be treated as if they had been converted as of
the Effective Time into a right to receive the Merger Consideration. The Company
shall give Buyer prompt notice of any demands received by the Company for

                                       5
<PAGE>
 
payment of the fair value of Shares, and Buyer shall have the right to
participate in all negotiations and proceedings with respect to such demands.
The Company shall not, except with the prior written consent of Buyer, make any
payment with respect to, or settle or offer to settle, any such demands.

     Section 1.05. Employee Stock Options and Share Units.  (a)  At or
immediately prior to the Effective Time, (i) each outstanding employee stock
option to purchase Shares granted under any employee stock option or
compensation plan or arrangement of the Company shall be canceled, and each
holder of any such option, whether or not then vested or exercisable, shall be
paid by the Company promptly after the Effective Time for each such option an
amount determined by multiplying (A)  the excess, if any, of the Merger
Consideration per Share over the applicable exercise price of such option by (B)
the number of Shares such holder could have purchased (assuming full vesting of
all options) had such holder exercised such option in full immediately prior to
the Effective Time, (ii) each outstanding share unit ("SHARE UNITS") granted or
otherwise issued under the Cable Michigan Executive Stock Purchase Plan (the
"PURCHASE PLAN") shall be canceled, and each holder of such share unit, whether
or not then vested, shall be paid by the Company promptly after the Effective
Time for each such Share Unit an amount, net of applicable withholding taxes
equal to the Merger Consideration per Share and (iii) each restricted Share
under the Purchase Plan shall be vested and converted into the Merger
Consideration in accordance with Section 1.02(c). Each employee stock option or
                                         -------
compensation plan or arrangement of the Company is listed on Schedule 3.16
hereto.

     (b)  Prior to the Effective Time, the Company shall (i) use its best
efforts to obtain any consents from holders of options to purchase Shares, share
units and restricted Shares granted under the Company's stock option or
compensation plans or arrangements and (ii make any permitted amendments to the
terms of such stock option or compensation plans or arrangements, and take any
other permitted actions thereunder, that, in the case of either clauses
1.05(b)(i) or 1.05(b)(ii), are necessary to give effect to the transactions
- ----------    -----------  
contemplated by Section 1.05(a). Notwithstanding any other provision of this
                        -------
Section, payment may be withheld in respect of any employee stock option or
Share Unit until any necessary consent from the holder thereof is obtained.

     Section 1.06.  Letter of Credit.  Concurrently with the execution hereof,
Buyer has delivered to First Union National Bank (the "ESCROW AGENT") a letter
of credit duly issued by NationsBank, N.A. (the "FIRST LETTER OF CREDIT") in the
amount of $10,000,000 in substantially the form attached hereto as Exhibit A.
On the 60th day after the date hereof, or on the following business day if such
60th day is not a business day, Buyer will, in addition, deliver to the Escrow
Agent a letter of credit duly issued by NationsBank, N.A. (the "SECOND LETTER OF
CREDIT") 

                                       6
<PAGE>
 
in the amount of $5,000,000 in substantially the form attached hereto as Exhibit
A. The First Letter of Credit is being, and the Second Letter of Credit will be,
delivered to the Escrow Agent pursuant to the terms hereof and the terms of the
Escrow Agreement dated the date hereof among Buyer, the Company, and the Escrow
Agent, a copy of which is attached hereto as Exhibit B. As used herein, the term
"LETTERS OF CREDIT" means the First Letter of Credit and the Second Letter of
Credit including in each case any renewal or replacement thereof as contemplated
by the Escrow Agreement, provided that if at the relevant time only the First
Letter of Credit has been delivered to the Escrow Agent, the term "Letters of
Credit" shall mean only the First Letter of Credit.

Corporation shall be changed to "Avalon Cable of Michigan Inc." or as otherwise
specified by Buyer.

     Section 2.02. Bylaws.  The bylaws of Merger Subsidiary in effect at the
Effective Time shall be the bylaws of the Surviving Corporation until amended in
accordance with applicable law.

     Section 2.03. Directors and Officers.  From and after the Effective Time,
until successors are duly elected or appointed and qualified in accordance with
applicable law, (a) the directors of Merger Subsidiary at the Effective Time
shall be the directors of the Surviving Corporation, and (b) the officers of
Merger Subsidiary at the Effective Time shall be the officers of the Surviving

                                   ARTICLE 3

                 Representations and Warranties of the Company

     The Company represents and warrants to Buyer that:

     Section 3.01. Organization and Authority.  The Company is a corporation
duly organized, validly existing and in good standing under the laws of the
Commonwealth of Pennsylvania, and has all requisite corporate power to carry on
its business as now conducted.  The Company is duly qualified to do business as
a foreign corporation and is in good standing in each jurisdiction where the
character of the property owned or leased by it or the nature of its activities
makes such qualification necessary, with such exceptions as would not have a
Material Adverse Effect (as defined below).  The execution, delivery and
performance by the Company of this Agreement, the Escrow Agreement, and the
Voting Agreement and the consummation by the Company of the transactions
contemplated hereby and thereby are within the Company's corporate powers and,
except for any required approval by the Company's stockholders in connection
with the consummation of the Merger, have been duly authorized by all necessary
corporate action.  Each of this Agreement, the Escrow Agreement, and the Voting
Agreement constitutes a valid and binding agreement of the Company, enforceable
against the Company in accordance with its terms, except (x) as the same may be
limited by applicable bankruptcy, insolvency, moratorium or similar laws of
general application relating to or affecting creditors' rights, and (y) for the
limitations imposed by general principles of equity.  The foregoing exceptions
(x) and (y) are hereinafter referred to as the "ENFORCEABILITY EXCEPTIONS."  The
Company has heretofore delivered to Buyer true and complete copies of the
Articles of Incorporation and Bylaws of the Company as in effect on the date
hereof.  For purposes of this Agreement, "MATERIAL ADVERSE EFFECT" means a
material adverse effect on the business, assets, operations, condition
(financial or otherwise), results of operations or the conduct of the business
of the Company and its Subsidiaries taken as a whole.  For purposes of this
Agreement, a "SUBSIDIARY," as to any Person, means any corporation or other
entity of which securities or other ownership interests having ordinary voting
power to elect a majority of the board of directors or other persons performing
similar functions are directly or indirectly owned by such Person.

     Section 3.02.  No Breach.  Except as set forth on Schedule 3.02, the
execution and delivery of this Agreement, the Escrow Agreement, and the Voting
Agreement by the Company do not, and the consummation of the transactions
contemplated hereby or thereby by the Company will not,  (i) violate or conflict
with the Articles of Incorporation or Bylaws of the Company, or (ii) constitute
a breach or default of, or give rise to any third-party right of termination,

                                       8
<PAGE>
 
cancellation, modification or acceleration under, any agreement, understanding
or undertaking to which the Company or any of its Subsidiaries is a party or by
which any of them is bound, or give rise to any Lien (as defined below) on any
of their properties, or (ii  subject to obtaining the approvals and making the
filings described in Section 3.03 hereof, constitute a violation of any statute,
                             ----
law, ordinance, rule, regulation, judgment, decree, order or writ of any
judicial, arbitral, public, or governmental authority having jurisdiction over
the Company or any of its Subsidiaries or any of their properties or assets,
with such exceptions in the cases of subsections (ii) and (iii) as would not
have, or reasonably be expected to have, a Material Adverse Effect or materially
interfere with or delay the transactions contemplated hereby.  For purposes of
this Agreement, "LIEN" means, with respect to any asset, any lien, claim,
charge, restriction, pledge, mortgage, security interest or other encumbrance in
respect of such asset.  Loans outstanding under the Company's credit facilities
may be repaid at any time (subject to customary notice provisions) without
penalty or premium, other than customary funding cost indemnities payable in
connection with payment of LIBOR loans other than on the last day of an interest
period applicable thereto.

     Section 3.03.  Consents and Approvals.  Neither the execution and delivery
of this Agreement, the Escrow Agreement, and the Voting Agreement by the Company
nor the consummation of the transactions contemplated hereby or thereby require
any consent, approval, authorization or permit of, or filing with or
notification to, any governmental or regulatory authority, except (i) for
filings required under the Securities Exchange Act of 1934, as amended, and the
rules and regulations thereunder (the "EXCHANGE ACT"), (ii) for notification
pursuant to, and expiration or termination of the waiting period under, the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and the rules
and regulations thereunder (the "HSR ACT"), (iii) for the filing of the articles
of merger and related filings as set forth in Section 1.01 hereof, (iv for
                                                      ---- 
notices to, or consents or waivers from, the relevant Franchising Authorities in
connection with a change of control of the holder of the Franchises of the
Company and its Subsidiaries, and the Federal Communications Commission ("FCC")
in connection with a change of control of the holder of the FCC licenses of the
Company and its Subsidiaries, (v) for those consents or waivers disclosed on
Schedule 3.03, (vi) corporate and shareholder approvals in connection with the
         ----
transactions contemplated by Section 7.07 hereof, and (vii) where the failure to
                                     ----                                
obtain such consents, approvals, authorizations or permits, or to make such
filings or notifications, would not have, and would not reasonably be expected
to have, a Material Adverse Effect or materially interfere with or delay the
transactions contemplated hereby.  For purposes hereof, "FRANCHISING AUTHORITY"
has the meaning that term is given by Section 602(10) of the Cable
Communications Policy Act of 1984 (47 U.S.C. Section 522(10)).  For purposes of
this Agreement, "FRANCHISE" means a written 

                                       9
<PAGE>
 
"franchise" within the meaning of Section 602(9) of the Cable Communications
Policy Act of 1984 (47 U.S.C. Section 522(9)).

     Section 3.04.  Approval of the Board; Fairness Opinion; Vote Required. The
Board of Directors of the Company has, by resolutions duly adopted at meetings
duly called and held, unanimously approved and adopted this Agreement, the
Escrow Agreement, the Voting Agreement, the Merger and the other transactions
contemplated hereby and thereby on the material terms and conditions set forth
herein and therein.  The Board of Directors of the Company has received the
opinion as of the date of this Agreement of Merrill Lynch & Co. ("MERRILL
LYNCH"), as financial advisor to the Company, that the consideration to be
received by the Company's stockholders (other than Buyer and its Subsidiaries)
in the Merger taken as a whole is fair to such stockholders from a financial
point of view, and such opinion has been made available to Buyer.  The
affirmative vote of a majority of the votes cast by the holders of Shares is the
only vote of the holders of the capital stock of the Company necessary to
approve the Merger under applicable law and the Company's Articles of
Incorporation and Bylaws.

     Section 3.05.  Capitalization.  The authorized capital stock of the Company
consists of 25,000,000 shares of Common Stock, par value $1.00 per share
(defined above as the "SHARES"), 50,000,000 shares of Class B Non-voting Common
Stock, par value $1.00 per share, and 10,000,000 shares of Preferred Stock, par
value $1.00 per share. As of May 31, 1998, there were outstanding (i) 6,896,342
Shares, (ii) employee stock options to purchase an aggregate of 396,513 Shares
with a weighted average exercise price of $11.50 per Share, and (iii) 12,246.5
Share Units (the 6,896,342 Shares referred to in subsection (i) include 12,246.5
Shares held in a grantor trust to offset the Company's obligation with respect
to the Share Units).  All outstanding shares of capital stock of the Company
have been duly authorized and validly issued and are fully paid and
nonassessable. Except as set forth in the first two sentences of this Section
and except for changes since May 31, 1998 resulting from (1) the exercise of
employee stock options outstanding on such date or (2) the item listed on
Schedule 3.05, there are outstanding no (a) shares of capital stock or other
voting securities of the Company, (b) securities of the Company convertible into
or exchangeable for shares of capital stock or voting securities of the Company,
(c) options or other rights to acquire from the Company, and no obligation of
the Company to issue, any capital stock, voting securities or securities
convertible into or exchangeable for capital stock or voting securities of the
Company or (d) stock appreciation rights or similar rights with respect to any
securities of the Company (the items in clauses 3.05(a), 3.05(b), 3.05(c) and
                                                -------  -------  ------- 
3.05(d) being referred to collectively as the "COMPANY SECURITIES"). There are 
- ------ 
no outstanding obligations of the Company or any Subsidiary of the Company to
repurchase,

                                      10
<PAGE>

knowledge, as of the date hereof there are no voting agreements, trusts or other
arrangements, agreements or understandings with respect to any Company
Securities, other than the Voting Agreement and as set forth on Schedule 3.16.
                                                                         ---- 

     Section 3.06. Subsidiaries. (a) Each of the Subsidiaries of the Company is
a corporation duly organized, validly existing and in good standing under the
laws of its state of incorporation. Each of the Subsidiaries of the Company has
all requisite corporate power to carry on its business as now being conducted.
Each Subsidiary of the Company is duly qualified to do business as a foreign
corporation and is in good standing in each jurisdiction where the character of
the property owned or leased by it or the nature of its activities makes such
qualification necessary, with such exceptions as would not have a Material
Adverse Effect. All Subsidiaries of the Company and their respective
jurisdictions of incorporation are listed on Schedule 3.06 hereto. Except as
                                                      ----     
set  forth on Schedule 3.06 and any marketable securities, the Company and its
                       ----
Subsidiaries do not have any investments in any other Person.

     (b)  Except as set forth on Schedule 3.06, all of the outstanding capital
stock of, or other ownership interests in, each Subsidiary of the Company, is
owned by the Company, directly or indirectly, free and clear of any Lien except
that the Company owns, directly or indirectly, only 61.92% of the outstanding
shares of Common Stock of Mercom, Inc., a Delaware corporation ("MERCOM"), and
Mercom owns, directly or indirectly, all of the issued and outstanding shares of
the Mercom Subsidiaries (as defined below). Other than as set forth on Schedule
3.06 or in connection with the transactions contemplated by this Agreement,
- ----
there are no outstanding (i) securities of the Company or any Subsidiary of the
Company convertible into or exchangeable for shares of capital stock or voting
securities in any Subsidiary of the Company, (ii) options or other rights to
acquire from the Company or any Subsidiary of the Company, and no other
obligation of the Company or any Subsidiary of the Company to issue, any capital
stock, voting securities or securities convertible into or exchangeable for any
capital stock or voting securities of any Subsidiary of the Company, or (iii)
stock appreciation rights or similar rights with respect to any securities of
any Subsidiary of the Company (the items in clauses 3.06(b)(i), 3.06(b)(ii) and
                                                    ----------  -----------
3.06(b)(iii) being referred to collectively as the "SUBSIDIARY SECURITIES").
- ------------
There are no outstanding obligations of the Company or any Subsidiary of the
Company to repurchase, redeem or otherwise acquire any outstanding Subsidiary
Securities. For purposes of this Agreement, "MERCOM SUBSIDIARIES" means Mercom
Services, Inc., a Nevada corporation, Communications and Cablevision, Inc., a
Michigan corporation, Coldwater Cablevision, Inc., a Michigan corporation, and
Allegan County Cablevision, Inc., a Michigan corporation. To the best of the

                                      11
<PAGE>
 
Company's knowledge, as of the date hereof there are no voting agreements,
trusts or other arrangements, agreements or understandings with respect to any
Subsidiary Securities.

     Section 3.07.  SEC Filings.  (a) The Company has made available to Buyer 
(i) its annual report on Form 10-K for its fiscal year ended December 31, 1997,
and its amendments to such report on Form 10K/A filed on April 30, 1998 and May
6, 1998 (as so amended, the "FORM 10-K"), (ii) its quarterly report on Form 10-Q

its other reports, statements, schedules and registration statements filed with

     (b)  As of its filing date (or in the case of the Form 10-K, as of May 6,
1998) each such report or statement filed pursuant to the Exchange Act complied
in all material respects with the applicable requirements of the Exchange Act
and did not contain any untrue statement of a material fact or omit to state any
material fact necessary in order to make the statements made therein, in the
light of the circumstances under which they were made, not misleading.

     (c)  Each such registration statement, as amended or supplemented, if
applicable, filed pursuant to the Securities Act of 1933, as amended (the
"SECURITIES ACT"), as of the date such statement or amendment became effective
complied in all material respects with the applicable requirements of the
Securities Act and did not contain any untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary to
make the statements therein not misleading.  Except for Mercom, none of the
Company's Subsidiaries is required to file any reports, forms or other documents

Subsidiaries (the "SYSTEMS") (i) had approximately 204,000 Basic Subscribers,
(ii) passed approximately 338,800 residential dwelling units and (iii) included

miles.  For purposes hereof, "BASIC SUBSCRIBER" means a customer of the Company
or any of its Subsidiaries who as of the relevant date satisfies all of the
following requirements:

          (i) such customer is connected to and receiving Basic Service from the
     Company or any of its Subsidiaries;

          (ii) such customer is being charged for the services received at the
     rate that the Company or such of its Subsidiaries generally charges to its
     customers in that location;

          (iii) such customer has paid to the applicable provider the applicable
     rate for all services received for one month (or more) of service prior to
     the relevant date;

     charges more than sixty (60) days delinquent from the due date therefore in

     shall be considered to be that number of Basic Subscribers which is equal
     to revenues from Basic Service generated by such hotel, motel or other
     customer for the month ending on the relevant date (or if such date is not
     the end of a month, the month ending immediately prior to such date)
     (without regard to non-recurring revenues from ancillary services such as
     installation fees) divided by the full rate charged to detached single
     family homes for such service in the relevant area by the applicable
     provider.

For purposes hereof, "BASIC SERVICE" means, for any given Franchise area, the
cable television service tier or tiers provided by the Company or any of its
Subsidiaries in such Franchise area which include the retransmission of local
off air television broadcast signals.

     (b) Except for (i) contracts, commitments and agreements entered into in
accordance with the terms of this Agreement, (ii) those contracts listed on
Schedule 3.22(b) (the "MATERIAL AGREEMENTS"), and (iii) the Franchises, neither

the Company nor any of its Subsidiaries is a party to or is bound by a contract,
commitment or agreement which is material to the Company and its Subsidiaries
taken as a whole or which involves payments of more than $500,000 in the
aggregate or which restricts the Company and its affiliates from engaging in any
business or which involves the purchase of programming by the Company. Schedule
3.22(b) sets forth a list, complete in all material respects, of the Franchises
- -------
of the Company or any of its Subsidiaries (the "FRANCHISES"). Each Franchise and
each Material Agreement is in all material respects the validly existing,
legally enforceable obligation of the Company or one of its Subsidiaries, as the
case may be, and, to the knowledge of the Company, of the other parties thereto,
subject to the Enforceability Exceptions. The Company and its Subsidiaries are
validly and lawfully operating in all material respects under their respective
Franchises and the Material Agreements to which they are a party. The Company
and its Subsidiaries have duly complied in all material respects with all of the
terms and conditions of each of their respective Franchises and each Material
Agreement to which they are a party. Except as set forth on Schedule 3.22(b),
                                                                     -------

exceptions as would not have a Material Adverse Effect, no Person (including any
governmental authority) has any right to acquire any interest in any System or
any assets of the Company or any of its Subsidiaries (including any right of
first 

                                      23
<PAGE>
 
refusal or similar right) upon an assignment or transfer of control of a
Franchise, other than rights of condemnation or eminent domain afforded by law.

     (d)  Neither the Company nor any of its Subsidiaries has made or is bound
by any material written commitments to any state, municipal, local or other
governmental commission, agency or body with respect to the operation and
construction of the Systems which are not fully reflected in their Franchises or
any Material Agreement.

     (e)  With such exceptions as would not have a Material Adverse Effect, no
Franchising Authority has advised the Company or any of its Subsidiaries in
writing, or otherwise formally notified the Company or any of its Subsidiaries
in accordance with the terms of the applicable Franchise, of its intention to
deny renewal of an existing Franchise held by the Company or any of its
Subsidiaries. With such exceptions as would not have a Material Adverse Effect,
neither the Company nor any of its Subsidiaries has received, nor has notice
that it will receive, from any Franchising Authority a preliminary assessment
that a Franchise should not be renewed as provided in Section 626(c)(1) of the
Communications Act, nor has the Company, any of its Subsidiaries, or any
Franchising Authority commenced or requested the commencement of an
administrative proceeding concerning the renewal of a Franchise as provided in
Section 626(c)(1) of the Communications Act.  With such exceptions as would not
have a Material Adverse Effect, the Company and its Subsidiaries have timely
filed pursuant to the formal renewal procedures established by Section 626(a) of
the Communications Act notices of renewal in accordance with the Communications
Act with all Franchising Authorities with respect to each Franchise expiring

Franchising Authority has commenced, or given notice that it intends to
commence, a proceeding to revoke a Franchise held by the Company or any of its
Subsidiaries.

     (f)  The Company and its Subsidiaries are operating the Systems in
compliance in all material respects with the provisions of the Franchises, the
Copyright Act, the Communications Act and the FCC Rules and Regulations,
including those  relating to carriage of signals, syndicated exclusivity,
network non-duplication, and retransmission consent. Without limiting the
foregoing and except as set forth on Schedule 3.22(f) or as would not have a

Section 76.605 of the FCC Rules and Regulations.

      (g)  (i) All television stations carried by the Systems are carried either
pursuant to retransmission consent agreements or must-carry elections (or must-
carry defaults) except as set forth in Schedule 3.22(g) (which Schedule includes
                                                -------
a description of the basis for the exception), (ii) the Company has delivered or

the Board of Directors of the Company shall be permitted to (i) not recommend to
the Company's stockholders that they give the Company Stockholder Approval or
(ii) withdraw or modify in a manner adverse to Buyer its recommendation to the
Company's stockholders that they give the Company Stockholder Approval, but in

action or inaction. The Company will (i) in connection with the Company
Stockholder Meeting, promptly prepare and file with the SEC, use all reasonable
efforts to have cleared by the SEC as promptly as practicable and thereafter
mail to its stockholders as promptly as practicable the Company Proxy Statement
and all other proxy materials for such meeting and (ii) unless, to the extent
permitted by the first sentence of this Section 5.02, the Board of Directors
                                                ----
shall not recommend to the Company's stockholders that they give the Company
Stockholder Approval or shall have withdrawn or modified in a manner adverse to
Buyer its recommendation, use reasonable best efforts to solicit proxies in
favor of the approval of this Agreement and the Merger, provided that the
obligation of the Company to cause the Company Proxy Statement and proxy to be
mailed to the Company's stockholders is subject to the Board of Directors of the
Company having received from Merrill Lynch confirmation of its opinion referred
to in Section 3.04 as of the date scheduled for mailing of the Company Proxy

Statement if the Board of Directors requests such a confirmation. For purposes
of this Agreement, "SUPERIOR PROPOSAL" means any bona fide Acquisition Proposal,
on terms that the Board of Directors of the Company determines in its reasonable
good faith judgment are more favorable to the Company's stockholders taken as a
whole than the transactions contemplated by the Agreement and with respect to

judgment, after consultation with its financial advisors, the Person making such
Acquisition Proposal has the financial means to consummate such Acquisition
Proposal. For purposes of this Agreement, "ACQUISITION PROPOSAL" means any offer
or proposal for a merger, consolidation or tender or exchange offer or other
business combination involving the Company or any Subsidiary of the Company or
the acquisition of any substantial equity interest in, or a substantial portion
of the assets of, the Company or any Subsidiary of the Company, other than the

the date hereof until the termination hereof, the Company (i) shall not
terminate, amend, modify or waive any provision of any confidentiality or
standstill agreement (other than any entered into in the ordinary course of
business not in connection with any Acquisition Proposal and other than as
permitted under the proviso to the first sentence of this Section 5.04) to which
                                                                  ----

future Tax asset of the Company, any of its

                                      35

and consummate the transactions referred to therein as soon as reasonably
practicable. Any such definitive agreement shall be in substantially the terms

and shall be reasonably acceptable to the Buyer. The Company shall not waive any
material term or condition thereunder without the consent of Buyer. The Company
shall be entitled to borrow money under its existing facilities to consummate
such transactions and any matter arising from such transactions that would
result in a breach of any of the representations and warranties in Article 3
                                                                           -

     Buyer agrees that:

     Section 6.01. Obligations of Merger Subsidiary. Buyer will take all action
necessary to cause Merger Subsidiary (and any affiliate of Buyer to which an
assignment is made as contemplated in Section 10.04) to perform its obligations
                                              -----
under this Agreement and to consummate the Merger on the terms and conditions
set forth in this Agreement.

     Section 6.02.  Voting of Shares.  Buyer agrees to vote all Shares
beneficially owned by it in favor of adoption of this Agreement at the Company
Stockholder Meeting.

     Section 6.03.  Director and Officer Liability.  For six years after the
Effective Time, Buyer will, and will cause the Surviving Corporation to, (i)
indemnify and hold harmless the present and former officers, directors and
employees of the Company in respect of acts or omissions occurring prior to the
Effective Time (including, without limitation, in respect of acts or omissions
in connection with this Agreement and the transactions contemplated hereby) to
the fullest extent permitted under the Company's Articles of Incorporation and
Bylaws and (ii) to the fullest extent permitted under applicable law, advance to
such Persons expenses incurred in defending any action or suit with respect to
which indemnity may be available under the Company's Articles of Incorporation
or Bylaws upon receipt from each such Person to whom expenses are advanced of an
undertaking reasonably satisfactory to Buyer to repay such advances if it is
ultimately determined that such Person is not entitled to indemnification.  In
the event any claim or claims are asserted or made within such six year period,
all rights to indemnification in respect of any such claim or claims shall
continue until disposition of any and all such claims. Any determination
required to be made with respect to whether any of the foregoing Persons is
entitled to indemnification as set forth above shall be made by independent
legal counsel selected mutually by such Person and Buyer.  For six years after
the Effective Time, Buyer will use its reasonable best efforts to provide
officers' and directors' liability insurance and fiduciary liability insurance
in respect of acts or omissions occurring on or prior to the Effective Time
covering each such Person currently covered by the Company's officers' and
directors' liability insurance policy and fiduciary liability insurance policy
on terms with respect to coverage and amount no less favorable in any material
respect than those of such policies in effect on the date hereof; provided that
in satisfying its obligation under this Section, Buyer shall not be obligated to
pay annual premiums in excess of $127,500; provided 

                                      36
<PAGE>
 
further that if the premiums would exceed such amount in a given year, Buyer
shall use its reasonable best efforts to purchase coverage that in the
reasonable opinion of Buyer is the best available for such amount per year.
Buyer may satisfy such obligation by purchasing officers' and directors'
liability and fiduciary liability run-off coverage for such six-year period

     Section 6.04.  Commitment Letters and Financing Agreements.  Buyer (a) will
not amend or otherwise modify the Commitment Letters in any material respect
adverse to Buyer or the Company without the prior consent of the Company which
will not be unreasonably withheld, (b) will use its reasonable best efforts to
obtain the Financing and (c) will keep the Company timely informed of the status
of the Financing and any material developments with respect thereto, including
without limitation informing it within two business days of its becoming aware
of any facts or circumstances that might reasonably be expected to result in (i)
the Commitment Letters being terminated or any of the material conditions
therein not being satisfied in any material respect with the result that
adequate Financing would not be available to effect the transactions
contemplated hereby, or (ii) the amount of the Financing to be provided pursuant
to the Commitment Letters or the Financing Agreements not being sufficient or
available to complete the transactions contemplated hereby.

     Section 6.05.  Cooperation.  In connection with the opinion referred to in
Section 8.04(c), Buyer will cooperate with, and provide reasonable access to
        -------
information regarding the Financing and Buyer to, the Company and the appraiser

appraiser as the appraiser retained by the Lender; provided that such appraiser
is reasonably satisfactory to Buyer).  The terms upon which any appraiser is
obtained shall be reasonably satisfactory to Buyer.

     Section 6.06. Merger Subsidiary Jurisdiction. Prior to the Effective Time,
either (i) Merger Subsidiary shall become a Pennsylvania corporation through
merger or otherwise or (ii) Merger Subsidiary shall assign its rights and
obligations hereunder to a Pennsylvania corporation.



                                   ARTICLE 7

                   Other Agreements of Buyer and the Company

     The parties hereto agree that:

                                      37
<PAGE>
 
     Section 7.01.  Reasonable Best Efforts.  Each of the parties hereto agrees
to use its reasonable best efforts to take, or cause to be taken, all
appropriate action, and to do, or cause to be done, all things necessary, proper
or advisable under applicable laws and regulations to consummate and make
effective the transactions contemplated by this Agreement in the most
expeditious manner practicable, including but not limited to the satisfaction of
all conditions to the Merger and seeking to remove promptly any injunction or
other legal barrier that may prevent or delay such consummation.  Each of the
parties shall promptly notify the other whenever a consent is obtained and shall
keep the other informed as to the progress in obtaining such consents.

     Section 7.02.  Certain Filings.  (a) The Company and Buyer agree to use
their respective reasonable best efforts to obtain all authorizations, consents,
orders and approvals of federal, state, local and foreign regulatory bodies and
officials and non-governmental third parties that may be or become necessary for
performance of their respective obligations pursuant to this Agreement, and will
cooperate fully with the other parties in promptly seeking to obtain all such
authorizations, consents, orders and approvals; provided that except as set
forth in the Capital Plan or in the 1999-2001 Capital Expenditure Summary set
forth in Schedule 7.02 (a) (the "CAPITAL SUMMARY") and with such other
exceptions as in the aggregate would not, and would not reasonably be expected
to, have a Material Adverse Effect or require in excess of $1,000,000 in capital
expenditures, nothing herein shall require Buyer or Merger Sub to agree to any
change to, or to make any commitments in respect of, any Franchise or License in
connection with obtaining any consent or approval required with respect to the
transactions contemplated hereby. The Buyer shall have primary responsibility,
with the assistance and cooperation of the Company and its Subsidiaries, for
obtaining all authorizations, consents, orders and approvals with respect to the
Company's and its Subsidiaries' Licenses and Franchises; provided, however, that
the Company and Buyer will have joint responsibility with respect to the joint
applications required for the transfers of Licenses under the rules and
regulations of the FCC.  Each of Buyer and the Company will use its reasonable
best efforts to ensure that all necessary applications in connection with
transfer of control of the Licenses and the Franchises are filed within twenty
days of the date hereof. Without limitation, the Company and Buyer shall each
use their reasonable best efforts to make an appropriate filing of a
Notification and Report Form pursuant to the HSR Act no later than twenty days
from the date hereof; and each such filing shall request early termination of
the waiting period imposed by the HSR Act.  For purposes of this Agreement,
"LICENSES" means approvals, consents, rights, certificates, orders, franchises,
determinations, permissions, licenses, authorities or grants issued, declared,
designated or adopted by any federal, state or municipal government or other
political subdivision or any department, 

                                      38
<PAGE>
 
commission, board, bureau, agency or instrumentality thereof, excluding,
however, the Franchises.

     (b)  Any application to any governmental authority for any authorization,
consent, order or approval necessary for the transfer of control of any License
or Franchise shall be reasonably acceptable to the Company and Buyer. Without
limiting the obligations of the Company and Buyer under Section 7.02(a), each of
                                                                -------
the Company and Buyer agrees, upon reasonable prior notice, to make appropriate
representatives available for attendance at meetings and hearings before
applicable governmental authorities in connection with the transfer of control
of any License or Franchise. Except as set forth in the Capital Plan or the
Capital Summary, and with such other exceptions as in the aggregate would not
have, and would not reasonably be expected to have a Material Adverse Effect or
require in excess of $1,000,000 in capital expenditures, neither the Company nor
any Subsidiary will agree to any changes to, or make any commitments in respect
of, any Franchise in connection with obtaining the consent of the Franchising
Authority for the transfer of control thereof.

     Section 7.03.  Public Announcements.  Buyer and the Company will consult
with each other before issuing any press release or making any public statement
with respect to this Agreement and the transactions contemplated hereby and,
except as may be required by applicable law or any listing agreement with any
national securities exchange, will not issue any such press release or make any
such public statement prior to such consultation.

     Section 7.04.  Notices.  Each party hereto shall promptly after obtaining
knowledge of the occurrence or threatened occurrence of, any fact or
circumstance that would cause or constitute, or would be reasonably likely to
cause or constitute, a material breach of any of its representations and
warranties set forth herein, give notice thereof to the other party.

     Section 7.05.  Employee Benefits.  (a) Unless otherwise provided herein,
with respect to the employees and former employees of the Company and its
Subsidiaries, Buyer agrees that the Company shall honor in accordance with their
respective terms and, on and after the Effective Time, Buyer shall cause the
Surviving Corporation and its Subsidiaries to honor, all Employee Plans, Benefit
Arrangements and all other written employment, severance, termination and
retirement agreements to which the Company or any of its Subsidiaries is a party
as of the Effective Time, including those Employee Plans and Benefit
Arrangements set forth in Schedule 3.16 to the extent such plans and
arrangements are maintained and sponsored by the Company or its Subsidiaries.

                                      39
<PAGE>
 
     (b)  Buyer agrees that, for a period of no less than three months after the
Effective Time, it shall, or shall cause the Surviving Corporation and its
Subsidiaries to, provide employee pension and welfare plans for the benefit of
employees and former employees of the Company and its Subsidiaries, that, in the
aggregate, are not materially less favorable than the Employee Plans and Benefit
Arrangements in effect immediately prior to the Effective Time.  To the extent
any benefit plan of Buyer (or any plan of the Surviving Corporation or any of
its Subsidiaries) shall be made applicable to any employee or former employee of
the Company or any of its Subsidiaries, Buyer shall, or shall cause the
Surviving Corporation and its Subsidiaries to, grant to employees and former
employees of the Company and its Subsidiaries credit for service with the
Company or any of its Subsidiaries prior to the Effective Time for the purposes
of determining eligibility to participate and the employee's nonforfeitable
interest in benefits thereunder and, unless a duplication of benefits would
thereby result, for calculating benefits (including benefits the amount or level
of which is determined by reference to an employee's vesting service)
thereunder.  In addition, to the extent any Buyer plan (or any plan of the
Surviving Corporation or any of its Subsidiaries) that constitutes an "employee
welfare benefit plan," as defined in Section 3(3) of ERISA, shall be made
applicable to any employee or former employee of the Company or any of its
Subsidiaries, Buyer shall, or shall cause the Surviving Corporation and its
Subsidiaries to, waive all preexisting condition exclusions and waiting periods
otherwise applicable to employees and former employees of the Company and its
Subsidiaries, except to the extent any such limitations or waiting periods in
effect under comparable plans of the Company and its Subsidiaries have not been
satisfied as of the date such plan is made so applicable.  Nothing in this
Agreement shall be interpreted as limiting the power of the Surviving
Corporation or any of its Subsidiaries to amend or terminate any Employee Plan,
Benefit Arrangement or any other employee benefit plan, program, agreement or
policy or as requiring the Surviving Corporation or any of its Subsidiaries or
Buyer to offer to continue (other than as required by its terms) any written
employment contract or to continue the employment of any given employee.

     Section 7.06.  Further Assurances.  At and after the Effective Time, the
officers and directors of the Surviving Corporation will be authorized to
execute and deliver, in the name and on behalf of the Company or Merger
Subsidiary, any deeds, bills of sale, assignments or assurances and to take and
do, in the name and on behalf of the Company or Merger Subsidiary, any other
actions and things to vest, perfect or confirm of record or otherwise in the
Surviving Corporation any and all right, title and interest in, to and under any
of the rights, properties or assets of the Company acquired or to be acquired by
the Surviving Corporation as a result of, or in connection with, the Merger.

     Section 7.07.  Mercom Minority Interest.  The parties hereto agree that
notwithstanding anything to the contrary set forth in this Agreement, the
Company shall be entitled (i) either (a) to negotiate and enter into an
agreement with Mercom (the "MERCOM AGREEMENT") to purchase the 1,822,810 shares
of Mercom Common Stock, par value $1.00 per share ("MERCOM SHARES") that the
Company does not own for cash consideration of $11.00 per share, or (b) to make
a cash tender offer (the "MERCOM TENDER OFFER") for such Mercom Shares at a
price of $11.00 per share, (ii) to consummate the purchase pursuant to such
Mercom Agreement or such Mercom Tender Offer, (iii) to borrow funds under the
Company's existing credit facilities for such purchase (and to amend such
facilities to permit such borrowings for such purpose) and (iv) to take such
customary actions in connection with the foregoing as the Company shall
reasonably conclude are appropriate.  The terms (other than the cash
consideration, which shall be as set forth above except as otherwise agreed by
Buyer and the Company) of any such Mercom Agreement or Mercom Tender Offer shall
be reasonably acceptable to Buyer and the Company will not waive any material
term or condition under such Mercom Agreement or Mercom Tender Offer without the
consent of Buyer.  No such transaction will be consummated involving the
acquisition of Mercom Shares without the approval of a committee of the Board of
Directors of Mercom composed solely of independent directors.  It is understood
and agreed that the closing of any such purchase may be conditioned upon the
closing of the Merger, that the closing of such purchase may occur before or
after the Effective Time, and that none of the entering into of an Mercom
Agreement, the commencement of an Mercom Tender Offer and the closing of any
such purchase pursuant to a Mercom Agreement or Mercom Tender Offer shall be a
condition to the Merger.  The Company shall use all reasonable efforts to ensure
that the fees and expenses incurred in connection with the foregoing
transactions are reasonable.

     Section 7.08.  Termination of Services. Effective as of the Effective Time,
the Company will terminate all services provided to it by R Corporation ("R")
and CTE under Section 6.01 of the Distribution Agreement among the Company, R 
                      ----
and CTE dated as of September 5, 1997, except for (i) customer and billing
services now provided to the Company out of RCN's Dallas, Pennsylvania office,
which services shall continue under the Distribution Agreement for 90 days after
the Effective Time (or such shorter period as elected by Buyer not less than
thirty days prior to the desired termination date) and (ii) the lockbox service
provided by CTE, which service shall continue under the Distribution Agreement
for 60 days after the Effective Time (or such shorter period as elected by Buyer
not less than thirty days prior to the desired termination date). Promptly (and,
in any event, within 30 days after) the receipt of an invoice therefor, the
Company will pay, without setoff or withholding, all amounts properly due to R
and CTE under such Distribution Agreement for services rendered prior to the
Effective

                                      41
<PAGE>
 
Time.  The 4% management fee charged by RCN to the Company under the
Distribution Agreement will accrue for the period up to the Effective Time but
as of the Effective Time will cease to accrue for future periods.  After the
Second Letter of Credit has been delivered to the Escrow Agent, the Company and
Buyer will cooperate to begin establishing a customer service center in a
mutually agreeable location in Michigan.  The Company will cooperate with Buyer
to arrange for RCN to continue to provide programming to the Systems for a
reasonable transitional period after the Effective Time.  The Company will
cooperate with Buyer in connection with Buyer arranging for the provision after
the Effective Time of the other terminated services.
