     In addition to a capital account, there shall be maintained for each 
partner an income account, which shall be credited or charged with the net 
profits and/or net losses of the PARTNERSHIP.

                                  ARTICLE XI

                                     Books
                                     -----

     The PARTNERSHIP shall keep, or cause to be kept, accurate books of account

upon such signature or signatures as the PARTNERSHIP shall designate from time 
to time.

                                 ARTICLE XIII

                     Voluntary Dissolution and Termination
                     -------------------------------------

     The PARTNERSHIP may be dissolved and terminated only upon approval of all
the partners. In the event of such election to dissolve and terminate, all
partners shall be given notice thereof and the partners (or a liquidating
partner selected and authorized by them) shall proceed with reasonable
promptness to wind up the business of the PARTNERSHIP. The method of winding up
the business of the PARTNERSHIP shall be either to sell the assets of the
PARTNERSHIP, in whole or in part, or to distribute the assets in kind. The
method of winding up the business of the PARTNERSHIP and the terms of such sale
or distribution shall be only as determined by all the partners. The assets of
the PARTNERSHIP, or the money or other property resulting from the sale of such
assets, shall be distributed in the following

                                      -4-

 
order: (1) to the creditors of the PARTNERSHIP, including any partner who is a
creditor of the PARTNERSHIP; (2) to the partners, in respect of their capital
contribution; (3) to the partners in respect of their share of any undistributed
profits in their income accounts; and (4) to the partners in accordance with
their percentages of profit and loss for the fiscal year in which such
distribution occurs in respect of any remaining funds.

                                  ARTICLE XIV

                                  Withdrawal
                                  ----------

     If any one or more but less than all of the partners desire to terminate or
withdraw from the PARTNERSHIP, they shall give notice of such desire to the 
remaining partners.  The partner or partners giving such notice are hereinafter 
referred to as the "withdrawing partner".  The withdrawing partner shall deliver
to the non-withdrawing partner or partners an offer (herein called the "Offer") 
in writing stating the price at which the withdrawing partner is willing to 
purchase all of the assets of the PARTNERSHIP and the terms and conditions upon 
which such price shall be payable.  The non-withdrawing partners shall within 
sixty (60) days after receipt of such Offer elect to either: (1) purchase the 
interest of the withdrawing partner at a price computed by multiplying the price
set forth in the Offer by the percentage of interest in the PARTNERSHIP of the 
withdrawing partner (any down-payments and deferred payments provided for in the
Offer shall be reduced in the same proportion as the reduction of the purchase
price provided for in the preceding sentence, but otherwise the purchase price
shall be on the same terms and conditions as contained in the Offer); or (2) the
PARTNERSHIP shall sell to the withdrawing partner and the withdrawing partner
shall purchase all of the assets of the PARTNERSHIP at a price and on the terms
and conditions set forth in the Offer; or (3) if less than all of the non-
withdrawing partners elect to purchase the interest of the withdrawing partner
pursuant to subparagraph (1) above, then the non-withdrawing partners who do not
elect to purchase shall be deemed to be withdrawing partners and the offer to
sell made by the first withdrawing partner shall be deemed to have been adopted
by said non-withdrawal


                                      -5-


 
partners who have not elected to purchase. If a non-withdrawing partner fails to
give the withdrawing partner notice of its election within the time hereinabove
provided for, it shall be conclusively presumed that the non-withdrawing partner
who has failed to give such notice has elected to sell to the withdrawing
partner pursuant to subparagraph (2) above. The closing of the purchase shall be
held in a mutually convenient place in Sarasota County, Florida, at a time
agreed upon by the partners, but not more than one hundred twenty (120) days
after the receipt of the Offer by the non-withdrawing partner. The PARTNERSHIP
of the partners, as the case may be, shall convey the property or their interest
in the PARTNERSHIP by appropriate instruments to the purchasing party free and
clear of all encumbrances save those to which the purchasing party has agreed
shall continue. The purchase or sale of the assets of the PARTNERSHIP or
PARTNERSHIP interest pursuant to this paragraph shall not terminate the
PARTNERSHIP and the partner or partners acquiring said assets or interest may
continue the PARTNERSHIP or wind up its business. If either the withdrawing
partner or non-withdrawing partner pursuant to the election provided above are
to purchase the assets or interest of the other but thereafter such partner
fails to close such purchase, then the non-defaulting partner may continue the
PARTNERSHIP and/or purchase the interest in the PARTNERSHIP of the defaulting
partner at the price set forth in the Offer multiplied by the percentage of
interest in the PARTNERSHIP of the defaulting partner in the manner and in
accordance with the time schedule set forth above.

                                  ARTICLE XV

                        Death, Bankruptcy, Incompetency
                        -------------------------------

        The death, bankruptcy or incompetency of a general partner shall not 
terminate the PARTNERSHIP and shall have no effect upon the continuing of the 
business of the PARTNERSHIP.  In the event of death or incompetency of a partner
having less than a majority in interest in the PARTNERSHIP, then the guardian 
or personal representative, as the case may be, of such partner shall become a 
partner in the PARTNERSHIP with the same interest


                                     - 6 -

 
in the profits, losses and capital of the PARTNERSHIP as possessed by the 
deceased or incompetent partner at the time of death or incompetency and with
the same rights and privileges as though originally named as a partner herein.
In the event of the death, bankruptcy or incompetency of a partner having a
majority in interest in the PARTNERSHIP, then the interest of such partner shall
immediately be transferred to Dennis J. McGillicuddy to be held by him in trust
for said partner in the case of incompetency or bankruptcy of said partner or
for the party who was to receive said interest in the event of the death of said
partner. During the period that said interest is so held in trust, the affairs
of the PARTNERSHIP shall continue to be conducted in accordance with the terms
of this PARTNERSHIP, and the authority and control attendant with the majority
in interest shall be exercised by Dennis J. McGillicuddy. The conflict arising
by virtue of Dennis J. McGillicuddy holding partnership interests both for
himself and in trust is hereby acknowledged by the partners, and such conflict
shall not be grounds for disqualification of Dennis J. McGillicuddy, who shall
be subject to removal only upon proof of actual breach of his fiduciary duties.
As trustee, Dennis J. McGillicuddy shall use his best efforts to liquidate the
interest held in trust upon such terms as are fair, reasonable and proper under
the circumstances within five (5) years from the date that such interest
commenced to be so held in trust. In the event that Dennis J. McGillicuddy is
unwilling or unable to hold such interest in trust, such interest shall be
transferred in trust to such party as shall be determined by the majority of
Dennis J. McGillicuddy, Martin Thaler and Michael McGillicuddy, or by a majority
of such of them as shall then be living. The party holding said interest in
trust shall have the same powers and duties as granted herein to Dennis J.
McGillicuddy and the party holding said interest in trust, including Dennis J.
McGillicuddy, may receive compensation for services rendered to the PARTNERSHIP
or for services rendered in behalf of the interest held in trust.

                                  ARTICLE XVI

                               Power of Attorney
                               -----------------

        The general partners, by the execution hereof, jointly and 


                                     - 7 -


 
severally, hereby irrevocably constitute and appoint those general partners that
have the authority to bind the PARTNERSHIP (in accordance with ARTICLE VII 
hereof), with full power of substitution, their true and lawful 
attorney-in-fact, in their name, place and stead, to make, execute, sign, 
acknowledge, record and file on behalf of each of them and on behalf of the 
PARTNERSHIP and and all instruments as may be deemed desirable by such general 
partners authorized to bind the PARTNERSHIP (in accordance with ARTICLE VII 
hereof) to carry out fully and completely the provisions of this AGREEMENT. The 
grant of authority set forth above: (1) is a Special Power of Attorney coupled 
with an interest; (2) is irrevocable and shall survive the death, bankruptcy, 
incompetency or withdrawal of the general partner granting the power; (3) may be
exercised by any of the general partners who form part of the majority of the 
general partners authorized to bind the PARTNERSHIP (in accordance with ARTICLE 
VII hereof) by using a facsimile signature or by listing all of the general 
partners executing any instrument with a single signature as attorney-in-fact 
for all of them; and (4) shall survive any transfer of a partner's interest in 
the PARTNERSHIP (whether by operation of law or otherwise).

                                 ARTICLE XVII

                           Liability of the Partners
                           -------------------------

     The partners shall not be liable, responsible or accountable, in damages or
otherwise to the PARTNERSHIP or any partner for any act, or failure to act, on 
behalf of the PARTNERSHIP that is within the scope of the authority conferred on
such general partners by this Agreement or by the Uniform Partnership Act of 
Florida or otherwise, unless such act or omission was performed or omitted 
fraudulently or in bad faith or constituted wanton and willful misconduct or 
gross negligence.

their agents from and against any loss, expense, damage or injury suffered or 
sustained by him by reason of any

                                      -8-

 
act, omission or alleged act or omission arising out of his activities on 
behalf of the PARTNERSHIP or in furtherance of the interests of the PARTNERSHIP 
including, but not limited to, any judgement, award, settlement, reasonable 
attorneys' fees, and other costs or expenses incurred in connection with the 
defense of any actual or threatened action, proceeding, or claim and including 
any payments made by any or all of the general partners to any of his attorneys 
or agents; provided that the act or omission upon which such actual or 
threatened action, proceeding or claim is based is not judicially determined to 
have been performed or omitted fraudulently or in bad faith or as a result of 
wanton and willful misconduct or gross negligence by any or all of the general 
partners or their agents.

                                  ARTICLE XIX

Corporation, Coaxial Communications, Inc., various corporations that are
subsidiaries or affiliates of Coaxial Communications, Inc., Coaxial Associates
of Columbus I, Coaxial Associates of Columbus II, and Coaxial Communications of

Corporation, or its subsidiaries, and Donald I. Grauer, which are secured by,
