ARTICLE II

FORMATION OF LIMITED PARTNERSHIP

2.1  Formation.  The Partners mutually covenant and agree and hereby do form a
limited partnership as of the effective date of this Agreement pursuant to the
provisions of the Act, in accordance with the further terms and provisions
hereof.

2.2  Name and Office.

(a)  The name of the Partnership is Cass Cellular Limited Partnership and its
business shall be carried on in this name with such variations and changes as
the General Partner deems necessary to comply with requirements of the
jurisdictions in which operations are conducted or as the General Partner
deems necessary to change for any reasonable business purpose.

(b)  The principal office and place of business of the Partnership shall be
maintained at Rochester Tel Center, 180 South Clinton Avenue, Rochester, New
York 14646 or at such other location as the General Partner may from time to
time select, upon prior written notice to the Limited Partners.

2.3  Business Purpose.  The purpose of the Partnership shall be to fund,
establish and provide Cellular Service, and to engage in any and all
activities related or incidental thereto.  It is understood and agreed that
Cellular Service provided by the Partnership directly or through its
involvement with another partnership or joint venture shall initially be
limited to the CGSA which is generally located within the boundaries of the
RSA, but may, subject to the provisions of this Agreement and applicable
licensing requirements, be expanded to include other areas.

2.4  Effectiveness of the Agreement.  This Agreement shall become effective no
later than the date the FCC conditionally dismisses or authorizes the
conditional dismissal or withdrawal of all applications other than that of the
Partnership or of a partnership or joint venture in which the Partnership is
involved, to provide Cellular Service.  The General Partner shall be
responsible for the filing of a Certificate of Limited Partnership with the
appropriate state authorities.  The Partners agree to take no action
inconsistent with the provisions of this Agreement and shall reasonably
support the Partnership's interest at all times.

2.5  First Partnership Meeting.  The first partnership meeting will be held
after the signing hereof and after reasonable notice as to time and place but
no later than ninety (90) days after the grant of the construction permit for
the RSA covered by this partnership agreement to RTCHC, the Partnership
directly, or any other partnership or joint venture in which the Partnership
may participate.

(a)  The Limited Partners shall be presented with a plan developed by the
General Partner to provide Cellular Service which may consist of Partnership
participation in a full or partial market settlement as a limited or general
partner if in the opinion of the General Partner the Partners are best served
thereby.  Participation by the Partnership in such full or partial market
settlement shall be contingent upon an affirmative vote of sixty percent (60%)
of the Partnership Interests.

(b)  Alternatively, the Limited Partners shall be presented with a three year
capital/network coverage plan developed by the General Partner ("initial
coverage plan"), consisting of the network design, coverage areas, equipment
and the amount and sources of funds necessary to complete same.  The General
Partner shall consult with the Limited Partners in the development of such
capital network coverage plan.

(c)  In the event that the initial coverage plan submitted by the General
Partner does not meet with the expectations of one or more of the Limited
Partners, the Limited Partner(s) will have the option of presenting an
expanded coverage plan to the General Partner with sixty (60) days of the
initial partnership meeting.

(d)  The General Partner shall review the expanded coverage plan and determine
if the initial coverage plan should include the expanded coverage plan.

If the General Partner determines that the expanded coverage plan should not
be included in the initial coverage plan, then the Limited Partner(s) shall
have the one time option to fund its expanded coverage plan.  All costs and
expenses of such additional coverage requested by the Limited Partner(s) will
be charged directly to those Limited Partner(s) supporting such a plan, and
the capital costs associated therewith will be charged to those Limited
Partner's capital account.  The respective interests of all Partners will be
adjusted to reflect the change contemplated herein.  Any increase in a Limited
Partner's Interest as a result of any reduction in the General Partner's
General Partner Interest under this Paragraph 2.5 shall not constitute that
Limited Partner as a General Partner hereunder.


ARTICLE III

REGULATORY MATTERS

3.1  Contingency.  The permits or licenses to be issued by regulatory
authorities in connection with the provision of Cellular Service may be
contingent during the pendency of litigation or regulatory action concerning
the present wireline allocation; however, the pendency of such litigation or
regulatory action shall not affect the Partners' obligations under this
Agreement.

3.2  Cooperation.  The Partners pledge their best efforts and mutual
cooperation to permit the Partnership to implement Cellular Service
expeditiously and to obtain all necessary approvals to provide Cellular
Service.

3.3  Operational Date.  The Partners recognize that the date when Cellular
Service can first be offered to the public depends upon the time required to
obtain cellular licenses for providing such Cellular Service and other
federal, state and local approvals, the time required to organize any
necessary proposed affiliated companies and to vest them with appropriate
authority to provide Cellular Service, and the time required to construct and
test the cellular system taking into account the General Partner's
construction schedule and the cellular system manufacturer's schedule.


ARTICLE IV

PARTNERSHIP OPERATIONS

4.1  Management and Operating Services.  The General Partner, on behalf of the
Partnership, shall be responsible for providing Cellular Service.  Such
provision may, consistent with provisions of Article 2.5(a) hereof, take the
form of Partnership participation in a full or partial market settlement as a
limited or general partner if in the opinion of the General Partner the
Partners are best served thereby.  Alternatively, the General Partner may
arrange for obtaining interconnection with the landline network, for operating
and maintaining the Cellular Service system, including but not limited to,
frequency coordination, engineering, construction and the ensuring of system
compatibility and for marketing Cellular Service.  In carrying out the
Partnership's responsibility to provide Cellular Service, the Partners hereto
agree that the General Partner shall perform all activities and/or functions
as the General Partner may deem necessary or appropriate to market, establish,
operate, maintain and manage the Cellular Service system or Partnership
participation in another partnership or joint venture.  The Limited Partners
agree to aid the General Partner and to take no action inconsistent with the
provisions of this Agreement and shall reasonably support the Partnership's
interest at all times.

The General Partner shall provide management and accounting services to the
Partnership, either directly or through  an affiliate, consisting of, but not
limited to, maintaining books of record, opening bank accounts, preparing
accounting reports (in accordance with generally accepted accounting
principles, as varied by appropriate regulatory authorities), and other
records or reports necessary to meet regulatory and legal filings, as the
General Partner may deem necessary or appropriate.

4.2  Operating and Management Expenses.  The General Partner shall be
reimbursed by the Partnership monthly for any reasonable and necessary
expenses incurred by the General Partner on behalf of the Partnership in
providing Cellular Service plus reasonable and necessary administrative and
general overhead expenses, including, but not limited to, marketing,
maintenance, message charges, facilities, engineering, customary legal,
accounting and auditing fees, development and implementation of billing
procedures, expense of preparing tax returns and reports, taxes, travel,
office rent, telephone, salaries (including social security, relief, pensions
and other benefits), and other incidental business expenses incurred by the
General Partner on behalf of the Partnership in connection with the provision
of Cellular Services.  The General Partner or any affiliate thereof shall not
be entitled to any profit in rendering such services to the Partnership, as
described in this paragraph, it being understood that the General Partner or
any affiliate thereof will be entitled to its proportionate allocated share of
Income and Losses as provided in Article VI.  Expenses incurred prior to the
date of the formation of the Partnership, except as stated in Section 5.3
below, shall not be reimbursed.

4.3  Ownership of Properties.  In addition to the properties contributed to
the Partnership by the General Partner pursuant to Section 5.3, the
Partnership shall acquire and hold in its name, directly or through license,
all real and personal property, equipment, software and other assets required
to provide Cellular Service.

4.4  Licenses.  The General Partner shall, on behalf of the Partnership and
consistent with Section 13.1, (a) cause to be transferred to the Partnership's
name all licenses, permits or other regulatory approvals necessary to provide
Cellular Service; and (b) if other local, state or federal licenses, permits,
certificates of convenience, franchises, or other approvals or authorities are
necessary to provide Cellular Service, make application to the appropriate
authority therefor.


ARTICLE V

CAPITALIZATION OF PARTNERSHIP

5.1  Initial Capital Contributions.  Initial Capital Contributions, in the
amount of Five Thousand Dollars ($5,000.00) for each Partner, shall be set
forth in Attachment A hereto, as such Capital Contributions may be modified
pursuant to Sections 2.5 and 5.3 and in accordance with the General Partner's
rights and powers in Sections 7.2 and 15.1.  Such initial Capital
Contributions shall result in the following respective Partnership Interests
for the partners:

(A)  10.00% for RTCHC as General Partner
(B)  10.00% for RTCHC as Limited Partner
(C)  20.00% for DEERFIELD as Limited Partner
(D)  20.00% for OGDEN as Limited Partner
(E)  20.00% for SAND CREEK as Limited Partner
(F)  20.00% for WALDRON as Limited Partner

Initial Capital Contributions shall be made within sixty (60) days of receipt
of written requests by the General Partner; provided, however, that no initial
Capital Contributions shall be made prior to issuance to the Partnership of
the FCC's permission to construct.  The Limited Partners shall notify the
General Partner within ten (10) days after receipt of such requests, each
notice stating whether or not the Limited Partner intends to make the
requested initial Capital Contribution.  The Partners understand that the
contribution schedule under this Article V is intended for the purpose of this
Agreement only and that the schedule may not reflect the full level of
expenditures (or Capital Contributions) appropriate for regulatory purposes.

5.2  Additional Capital Contributions.  From time to time additional capital
may be required to be invested by the Partnership to fund expansion or
operation of Cellular Service.  In the event the General Partner determines
that additional capital is so needed, each Partner shall be entitled to
provide all (but not part of) its share of additional capital in proportion to
its then current Partnership Interest.  This additional funding is due and
payable on the date set forth in a written notice requesting an additional
Capital Contribution given by the General Partner to a Partner, which date
shall not be less than sixty (6) days from the date of the notice.  The
Limited Partner shall notify the General Partner within ten (10) days after
receipt of such requests, each notice stating whether or not the Limited
Partner intends to make the requested additional Capital Contribution.  Should
any Partner decline to make such additional Capital Contribution, or fail to
pay its contribution when due, the other Partners may contribute pro rata,
according to their then current respective Partnership Interests, an aggregate
amount equal to the additional Capital Contribution declined by the
non-participating Partner(s), thereby increasing their interest in such
proportion to the other Partners' Partnership Interests (it being understood
that the General Partner may make such additional Capital Contribution as a
Limited Partner, if it desires).  In such event, the Partnership Interest of a
non-participating Partner shall be diluted accordingly and such Partner shall
be limited in its right to provide future additional capital in proportion to
its Partnership Interest as so revised.

5.3  Capital Contributions in Cash.  Funding of both initial and additional
Capital Contributions to the Partnership shall be in cash and not real or
personal property, provided, however, that with respect to its initial Capital
Contribution the General Partner for its Partnership Interest as General
Partner and as a Limited Partner may contribute, in lieu of or in addition to
cash, real property (including buildings), equipment acquired and other direct
expenses incurred in anticipation of and for use by the Partnership in the
provision of Cellular Service.  The approximate or actual cost associated with
and directly related to the acquisition of such real property (including
buildings), equipment and other direct expenses incurred is set forth in
Attachment A.  The value of such contributed real property (including
buildings), equipment acquired and other direct expenses incurred is to be
determined on the basis of acquisition cost plus interest calculated at the
General Partner's average cost of debt, compounded annually from the date of
acquisition to the date by which all other initial Capital Contributions have
been received.  The Partners recognize the General Partner may have acquired
and may continue to acquire real property (including buildings), and equipment
and incur other direct expenses in anticipation of and for use by the
Partnership in the provision of Cellular Service.  Additional real property
(including buildings) and equipment may be purchased between execution of this
Agreement and the date when the initial Capital Contribution is made;
therefore, Attachment A may not list all such real property (including
buildings), equipment and direct expenses the General Partner would contribute
to the Partnership.  In the event such further property, equipment, or direct
expenses is contributed (a) it shall be valued as set forth in this Section
5.3, and (b) its value shall be deducted from the cash portion of the General
Partner's initial Capital Contribution as set forth in Attachment A.

5.4  Additional Limited Partners.  In providing Cellular Service within the
RSA, the General Partner may invite one or more carriers to become additional
Limited Partners hereunder subject to approval by at least sixty percent (60%)
of the Limited Partners.  Similarly, in providing Cellular Service outside the
RSA covered by this Agreement the General Partner shall have the right to
invite one or more carriers not affiliated with the General Partner to become
additional limited partners hereunder upon the approval of sixty percent (60%)
of the Limited Partners.  The Limited Partners hereby consent to amend this
Agreement to reflect any such inclusion.  In the event of any such addition
(a) the new Limited Partner shall participate in the Partnership on the same
terms and conditions described herein (or as hereafter amended), and (b) the
Partnership Interests of the other Partners shall be adjusted according to
their then current respective Partnership Interests.


ARTICLE VI

ALLOCATIONS AND DISTRIBUTION

6.1  Capital Accounts.  A capital account shall be established for each
Partner in such Partner's Initial Capital Account Amount.  Such capital
accounts shall be increased to reflect allocable shares of Income, as defined
in Section 1.8, and additional Capital Contributions pursuant to Section 2.5,
5.2 and 5.4, and decreased to reflect allocable shares of Losses, as defined
in Section 1.8, and cash distributions made by the Partnership.  For purposes
of this Section 6.1, Income and Losses shall be apportioned ratably to each
day of the fiscal period and each day's share shall be allocated pursuant to
the Partnership Interests on such date.  In the case of distributions in kind
pursuant to Section 14.3, capital accounts shall be adjusted in accordance
with Section 14.3.

6.2  Tax Allocations Among Partners.  All items of income, gain, loss,
deduction and credit (including items of tax preference) of the Partnership
for Federal income tax purposes shall be apportioned ratably to each day of
the Partnership's taxable year and each day's share of such items shall be
allocated to the Limited Partners and to the General Partner in proportion to
their respective Partnership Interests on such days, provided however,
depreciation and gain or loss recognized for Federal income tax purposes with
respect to property contributed to the Partnership shall be allocated to the
Limited Partners (other than the Limited Partner who is also the General
Partner) as though such property had been purchased by the Partnership at its
Agreed Value.  The remainder of any depreciation and gain or loss recognized
for Federal income tax purposes with respect to such contributed property
shall be allocated to the General Partner in respect of its General Partner's
Interest and Limited Partner's Interest proportionately.

6.3  Distributions.  Funds of the Partnership from all sources, less
appropriate reserves as are determined by the General Partner to be reasonably
necessary for future administrative and operating expenses, loan payments and
other costs and expenses and contingencies, shall be distributed on a fiscal
quarterly basis as promptly as practicable after the end of each quarter. 
Each distribution pursuant to this Section 6.3 shall be made to the Partners
in proportion to the daily weighted average of their respective Partnership
Interests as in effect from time to time during the relevant quarterly time
period.

6.4  Tax Compliance.  It is the intention of the Partners that each Partner's
distributive share of tax items shall be determined and allocated in
accordance with the allocation provisions of this Agreement.  If the General
Partner reasonably determines that the allocation provisions of this Agreement
are unlikely to be respected for federal income tax purposes, due to the
application of Internal Revenue Code sections 704(b) and (c), the regulations
promulgated thereunder, or otherwise, the General Partner shall recommend
appropriate amendments to this Agreement in order to effectuate the allocation
provisions contemplated therein.

conditions equivalent to the prices, terms and conditions of any agreements
between the Partnership and other resellers of Cellular Service.

8.8  Cellular Service in Other Areas.  Nothing herein shall preclude the
General Partner or an Affiliate thereof from providing Cellular Service
independently from the Partnership in areas other than the RSA.


ARTICLE IX

9.2  Maintenance of Books and Accounting Method.  The General Partner shall
keep or cause to be kept full and accurate accounts of the transactions of the
Partnerships in proper books of account in accordance with generally accepted

LIMITED PARTNERS

10.1  Limited Partners Not to Take Part in Business.  The Limited Partners,
acting in their capacity as a Limited Partner, shall not take part in, or
interfere in any manner with, the conduct or control of the Partnership
business, nor shall the Limited Partners have any right or authority to act
for or bind the Partnership.

10.2  Limitation on Liability of Limited Partners.  The liability of each
Limited Partner to provide funds or any other property to the Partnership
shall be limited to the amount of Capital Contributions which the Limited
Partner makes or otherwise agrees to make pursuant to the provisions of
Article V.  The obligation of any Limited Partner to return any distributions
previously made shall be as set forth in the Act.  Subject to the provisions
of the Act, the Limited Partner shall have no further liability to contribute
money to the Partnership for, or in respect of, the liabilities or obligations
of the Partnership and shall not be personally liable for any obligations
under the Partnership.

10.3  Resale of Cellular Service.  Nothing herein shall preclude any Limited
Partner or an Affiliate thereof from reselling Cellular Service or selling or
leasing terminal equipment used in connection with Cellular Service
independently from the Partnership whether within or outside the RSA.  Neither
the Limited Partners nor any Affiliates thereof shall be funded or staffed by
the Partnership for such provision of Cellular Service or resale activities
and any transactions between any such Limited Partner or Affiliate and the
Partnership shall be on an arms-length basis and on prices, terms and
conditions equivalent to the prices, terms and conditions of any agreements
between the Partnership and other resellers of Cellular Service.

10.4  Cellular Service in Other Areas.  Nothing herein shall preclude any
Limited Partner or an Affiliate thereof from providing Cellular Service in
areas other than the RSA.  In addition, after a five-year period commencing
with the date that the Partnership obtains a construction permit from the FCC,
nothing herein shall preclude any Limited Partner or Affiliate thereof from
providing Cellular Service in areas within the RSA provided that the
Partnership has refused to approve a change in the CGSA to provide service in
the RSA which the Partner desires to serve.  No partner, however, may seek
such approval if that Partner has voted against authorizing the Partnership to
provide Cellular Service in the area under consideration.  Any such Limited
Partner or Affiliate shall however withdraw from the Partnership pursuant to
Article XII prior to seeking any regulatory approval to provide Cellular
Service within the RSA.


ARTICLE XI

TRANSFER OF LIMITED PARTNER'S INTEREST

11.1  Limitation on Transfer; Right of First Refusal.  Any Limited Partner may
transfer its Partnership Interest to an Affiliate thereof at any time without
any consent or restriction from the General Partner or any other Limited
Partner.  Otherwise, there shall be no sale, exchange or other transfer or
assignment of the whole or any portion of any Limited Partner's Interest
without the prior written consent of the General Partner, which consent shall
not be unreasonably withheld.  In addition, before any Limited Partner sells,
exchanges or transfers any part of its Partnership Interest to a non-Affiliate
of such Limited Partner, it shall offer, by giving written notice to the
General Partner, that interest to all of the other Partners for the price and
on the terms at which such non-Affiliate has offered in writing to acquire
such interest.  The General Partner, in turn shall forward such notice to all
other Limited Partners.  Each Partner shall initially be entitled to purchase
that fraction of the offering Partner's Interest equal to its Partnership
Interest divided by the Partnership Interests of all non-selling Partners.  If
any Partner declines to exercise its right of purchase hereunder, the
remaining Partner(s) electing to exercise that right shall be entitled to
purchase that portion of the interest intended to be sold that has been
declined by the other Partner(s) in amounts determined pursuant to
reapplication of the principles set forth in this Section 11.1, excluding from
consideration the Partnership Interests of the selling and declining Partners.

Each non-selling Partner shall notify the General Partner and the selling
Limited Partner, in writing, of its intention to exercise or not to exercise
its purchase rights hereunder within thirty (30) days following receipt of the
offer of sale.  The General Partner shall promptly notify each Limited Partner
of the elections by the other Limited Partners.  Subsequent written
notifications, if necessary, shall be required within ten (10) days after
receipt by the Limited Partners which have not previously declined to exercise
their rights of purchase, of their intentions with respect to that portion of
the selling Limited Partner's Partnership Interest still subject to a right of
purchase.

11.2  Substitute Limited Partner.  No assignee, purchaser or transferee of the
whole or any portion of any Limited Partner's Interest shall have the right to
become a substitute Limited Partner, unless:

(a)  The transferring Limited Partner has designated such intention in a
written instrument of assignment, sale or transfer, a copy of which has been
delivered to the General Partner;

(b)  The transferring Limited Partner has obtained the written consent of the
General Partner, which consent shall not be unreasonably withheld;

(c)  The person acquiring the Limited Partner's Interest has adopted and
agreed in writing to be bound by all of the provisions hereof, as the same may
have been amended;

(d)  All documents reasonably required by the General Partner and the Act to
effect the substitution of the person acquiring the Limited Partner's Interest
as a Limited Partner shall have been executed and filed at no cost to the
Partnership; and

(e)  Any necessary prior consents have been obtained from any regulatory
authorities.

Provided, however, that subsections (a) and (b) above shall not apply in the
case of an assignment or sale to an Affiliate of the assignor or seller.

11.3  Indemnification.  Each Limited Partner transferring a Limited Partner's
Interest hereby indemnifies the Partnership and the other Partners against any
and all loss, damage or expense (including, without limitation, tax
liabilities or loss of tax benefits) arising, directly or indirectly, as a
result of any transfer or purported transfer in violation of any provision
contained in this Article XI.

11.4  Distribution and Allocation Subsequent to Transfer.

(a)  The Income and Losses of the Partnership attributable to any Partnership
Interest acquired by reason of the assignment of the Partnership Interest or
substitution of a Partner with respect to that Interest and any distributions
made with respect thereto shall be allocated between the assignor and assignee
based upon the length of time during any fiscal year of the Partnership, as
measured by the effective date of the assignment or substitution, that the
Partnership Interest so assigned or with respect to which there is a
substitution was owned by each of them.

(b)  The effective date of an assignment, sale or transfer of the Limited
Partner's Interest or any portion thereof shall be the date on which written
consent has been obtained from the General Partner as provided in Section
11.2(b).


ARTICLE XII

WITHDRAWAL BY LIMITED PARTNER

12.1  Withdrawal.

(a)  Effective upon thirty (30) days written notice to each Partner, any
Limited Partner may withdraw from the Partnership subject to any required
regulatory approval;

(b)  Any Limited Partner shall promptly withdraw from the Partnership upon the
occurrence of default in performance by such Limited Partner of any obligation
under this Agreement if such default shall not be corrected within sixty (60)
days after the same shall be called to the attention of such Limited Partner
by the General Partner by written notice specifying the thing or matter in
default and the General Partner chooses to insist upon such withdrawal;
provided, however, that such sixty (60) day period shall cease to run during
the pendency of any arbitration proceeding institute pursuant to Section 19.9
to determine the existence of such a default.  The General Partner shall
notify each nondefaulting Limited Partner of such default in performance;

(c)  Any Limited Partner shall promptly withdraw upon the bankruptcy or
assignment for the benefit of creditors of such Limited Partner;

(d)  Any Limited Partner shall promptly withdraw upon failure by such Limited
Partner to make its initial Capital Contribution pursuant to Section 5.1;

(e)  Upon withdrawal pursuant to (a), (b) or (c) above, the Limited Partner so
withdrawing shall, subject to the provisions of Section 12.2, receive
distribution of its capital account in cash; and

(f)  Upon withdrawal pursuant to (a), (b), (c) or (d) above, the proportionate
Partnership Interests of the remaining Limited Partners shall be increased pro
rata to reflect such withdrawal.

12.2  Distribution on Withdrawal.  If distribution is made pursuant to Section
12.1, amounts payable to the Limited Partner so withdrawing shall be paid to
such Limited Partner by the Partnership and may at the General Partner's
option and consistent with regulatory and other legal constraints, be paid
over a period not to exceed three (3) years in order to provide the
Partnership sufficient time to raise capital to replace that capital being
withdrawn and to ensure the continued provision of Cellular Service.  In such
event, the Limited Partner so withdrawing shall be entitled to interest on the
amounts payable to such Limited Partner.  Such interest shall be calculated at
a rate equal to the average of the then current prime interest rate which has
been charged on new borrowings by Citibank N.A., the Chase Manhattan Bank
N.A., and Morgan Guaranty Trust Company of New York as applied to the
outstanding balance due.


ARTICLE XIII

TRANSFER OF GENERAL PARTNER'S INTEREST

13.1  Assignment.  The General Partner may transfer or assign its General
Partner's Interest only after written notice to all the other Partners and the
unanimous vote of all the other Partners to permit such transfer and to
continue the business of the Partnership with the assignee of the General
Partner as General Partner.  Any such transfer or assignment shall be subject
to required regulatory approval.

13.2  Withdrawal.  Withdrawal of the General Partner will cause the
dissolution and termination of the Partnership in accordance with the terms of
Article XIV except in the case of assignments as provided in Sections 11.1 and
13.1.  The General Partner may not withdraw until it has given the other
Partners ninety (90) days' notice.  If during that time the other Partners
unanimously designate a substitute General Partner who will agree both to
purchase the General Partner's Interest and its Limited Partner's Interest, on
terms acceptable to the General Partner, and continue the business of the
Partnership, subject to required regulatory approval, the General Partner
agrees to transfer or assign its Interests to the designated General Partner. 
The General Partner shall not unreasonably withhold its acceptance of terms
for purchase of its Partnership Interest proposed by the substitute General
Partner.



ARTICLE XIV

DISSOLUTION AND TERMINATION OF LIMITED PARTNERSHIP

14.1  Dissolution.  The Partnership shall be dissolved and terminated if:

(a)  The FCC approves this Agreement subject to terms and conditions that are
unacceptable to both the General Partner and one Limited Partner which is not
also the General Partner and all available administrative and judicial appeals
of such FCC approval have been finally exhausted;

(b)  The Cellular Radio Decisions are not continued in substantially the same
form and such change materially and adversely impacts the Partnership's
ability to conduct its business and all available administrative and judicial
appeals regarding such Cellular Radio Decisions have been finally exhausted;

(c)  The FCC finally denies to the Partnership licenses empowering it to
construct and provide Cellular Service;

(d)  The Partnership applies for and is finally denied state or other
regulatory approvals or is granted such approval subject to terms and
conditions that are unacceptable to both the General Partner and one Limited
Partner that is not also the General Partner on the grounds that such denial
or conditional grant has a materially adverse impact on the Partnership's
ability to conduct its business; or

(e)  The Partners unanimously agree to dissolve and terminate the Partnership
and receive any approvals required by the FCC or any other regulatory
authority for such dissolution and termination.

Regarding (c) and (d) above, any such denial of regulatory approval shall not
be considered finally denied until all available administrative and judicial
appeals of such denial have been finally exhausted.

14.2  Distribution Upon Dissolution.  Upon dissolution of the Partnership, the
General Partner shall proceed, subject to the provisions herein, to liquidate
the Partnership and apply the proceeds of such liquidation or to distribute
Partnership assets, in the following order of priority:

(a)  To creditors, including Partners who are creditors, to the extent
otherwise permitted by law, in satisfaction of liabilities of the Partnership
other than liabilities for distribution to Partners under Articles XII and
XIII;

(b)  To the establishment of any reserve which the General Partner may deem
reasonably necessary for any contingent or unforeseen liabilities or
obligations of the Partnership.  Such reserve may be paid over by the General
Partner to any attorney at law, or other acceptable party, as escrow agent to
be held for disbursement in payment of any of the aforementioned liabilities
and, at the expiration of such period as shall be deemed advisable by the
General Partner, for distribution of the balance, in the manner hereinafter
provided in this Section 14.2;

(c)  To Partners and former Partners in satisfaction of liabilities for
distributions under Articles XII and XIII; and

(d)  To Partners first for the return of their capital accounts as set forth
in Section 6.1 in proportion to the Partners' respective capital accounts at
the time of such dissolution, with any remaining Partnership assets being
distributed in proportion to the Partner's respective Partnership Interests on
the date of dissolution.

14.3  Distributions in Cash or in Kind.  Upon dissolution, the General Partner
may in its discretion (a) liquidate all or a portion of the Partnership assets
and apply the proceeds of such liquidation in the priorities set forth in
Section 14.2 or (b) hire independent recognized appraisers to appraise the
value of the Partnership assets not sold or otherwise disposed of (the cost of
such appraisal to be considered a debt of the Partnership), allocate any
unrealized gain or loss to the Partners' capital accounts as though the
properties in question has been sold on the date of distribution and, after
giving effect to any such adjustment, distribute said assets in accordance
with the priorities as set forth in Section 14.2.  The General Partner may
determine in its sole discretion whether undivided portions of assets
distributed in kind will be distributed pro rata to Partners in accordance
with their respective Partnership Interests at the time of dissolution;
provided, however, that any distributions of unrealized receivables or
substantially appreciated inventory within the meaning of Section 751 of the
Internal Revenue Code shall be made proportionately to the Partners'
Partnership Interests at the time of dissolution unless the Partners otherwise
unanimously agree.  In the case of any distribution in kind of Partnership
assets under this Section to a Partner, the value of the asset determined by
the appraisal as provided above shall be applied against the Partner's capital
account.

14.4  Time for Liquidation.  A reasonable amount of time shall be allowed for
the orderly liquidation of the assets of the Partnership and the discharge of
liabilities to creditors so as to enable the General Partner to minimize any
losses which otherwise might be incurred.

14.5  Termination.  Upon compliance with the foregoing distribution plan the
Partnership shall cease to be such, and the General Partner shall execute,
acknowledge and cause to be filed a certificate of dissolution of the
Partnership pursuant to the power of attorney contained in Article XV.

14.6  General Partner Not Liable for Return of Distribution.  The General
Partner shall not be liable for any distribution required pursuant to Sections
14.2(b), (c) and (d) and such distribution shall be made solely from available
Partnership assets, if any.

14.7  General Partner's Right to Continue Providing Cellular Service.  Each
Limited Partner hereby agrees that, in the event that such Limited Partner
withdraws pursuant to Article XII or the Partnership is dissolved pursuant to
Articles XIII or XIV, the General Partner shall have the right to provide
Cellular Service either singly or with others, subject to any necessary
regulatory approval.  In such event, the General Partner shall invite all
other parties to this Agreement, including their successors and assigns, to
participate in a new partnership to carry out such business.  The terms of any
such offer made hereunder shall be substantially on the same terms and
conditions as those contained in this Agreement.  In the event that any party
declines to contribute capital to the new partnership, as may be required,
that party's interest shall be diluted accordingly.  Until such partnership is
formed, if at all, the General Partner shall have the right to continue to
provide Cellular Service, subject to any necessary regulatory approval.

XV, the General Partner may not modify the terms of this power of attorney or
this Agreement without the written consent of all the Limited Partners.  The

or liability of any Limited Partner without the written consent of such
Limited Partner.
