Section 368(a) of the Code.

information concerning the interest in the Partnership, its business and
financial condition and is not relying on any representation of any Stockholder

     9. Governmental Filings. Each of the parties hereto shall (i) make promptly
        --------------------

         ----------------------                                             
all reasonable efforts to cause to be filed and declared effective as soon as
reasonably practicable a Registration Statement to permit the public resale of
the Shares acquired by the Stockholders pursuant hereto (the "Resale"). Any
obligation to permit the Resale under the Registration Statement shall expire on

          (b) If at any time prior to the filing of the Registration Statement

                     ---- ----                                                
or (ii) Cellular then is unable to comply with its disclosure obligations or SEC
requirements in connection with the Registration Statement, then in either such
case Cellular shall not be required to file the Registration Statement or
maintain the effectiveness thereof or amend or supplement the Registration
Statement for a period (an "Information Delay Period") expiring upon the earlier
to occur of (A) the date on which such material information is disclosed to the
public or ceases to be material or Cellular is able to so comply with its
disclosure obligations and SEC requirements or (B) 30 days, in the case of
clause (i) above, or 45 days, in the case of clause (ii) above, after counsel to
Cellular makes such good faith determination.

          (c) Cellular will give prompt written notice to Stockholders of the
commencement of an Information Delay Period (and duration). Each Stockholder, by
his acceptance of any Shares, agrees that, upon receipt of such notice it will
forthwith discontinue disposition of the Shares pursuant to the Registration
Statement, and will not deliver any prospectus forming a part thereof in
connection with any sale of Shares until the expiration of an Information Delay
Period.

          (d) Notwithstanding anything in this Agreement to the contrary, if the
Registration Statement referred to in this Section 10 has not been declared
effective by July 1, 1996, then Cellular shall issue to Assignor (or its
assigns) a stock

 
certificate or stock certificates evidencing an aggregate of such number of
additional Shares as shall equal 5% of the amount set forth in Section 1(b)
hereof. If the Registration Statement referred to in this Section 10 has not
been declared effective by December 1, 1996, then Assignor (or its assigns)
shall have the right by giving written notice to Cellular to require Cellular to
purchase from Assignor in 1996 up to 100,000 Shares that were issued to Assignor
pursuant to this Agreement. The price per share in any such redemption shall be
equal to the average of the daily closing price on NASDAQ (or any exchange or
other securities trading market which is the principal place of trading for
Cellular's common stock at the time) for the seven trading days immediately
preceding the date on which notice of the redemption is given. Payment for such
Shares shall be made not later than three business days following delivery of
such notice.

          (e) If at any time Cellular shall file an amendment to the
Registration Statement, Cellular shall promptly deliver copies of such amendment
to the Stockholders .

     11. Indemnification bv the Stockholder. Cellular, CCPR and its affiliates
         ----------------------------------                                   
shall jointly and severally be indemnified and held harmless by Assignor and
each Stockholder against any and all losses, expenses, damages, injuries,
judgments, claims and liabilities, including reasonable attorney's fees and
litigation expenses ("Losses"), arising from (a) Assignor's ownership of its
Interest prior to the Closing; (b) any material misrepresentation, breach of
warranty, or nonperformance of any obligation hereunder on the part of Assignor
or any Stockholder; (c) any other act or omission on the part of Assignor or any
Stockholder, its agents or representatives in connection with its Interest in
any Partnership; (d) any agreement, commitment or obligation of Assignor or any
Stockholder undertaken in connection with the Interest or the Partnership (and,
in the case of Assignor, arising prior to the Closing) which CCPR does not
expressly and specifically assume either hereunder or in writing prior to the
Closing, (e) Assignor's ownership, operation or conduct of any asset or business
other than the Interest, (f) any liability for any federal, state or local tax
(including interest, penalty or addition thereto) of Assignor incurred on or
prior to the Closing, or (g) based on an untrue statement of fact in the
Information or alleged omission to state therein a material fact necessary to
make the statements therein not misleading, or the failure of any Stockholder to
effect a Prospectus Delivery; provided, that no indemnification shall be due to
Cellular or any of its affiliates for any Loss resulting solely from an action
taken by Cellular in its capacity as managing general partner of the
Partnership. Notwithstanding anything in this Agreement to the contrary, each of
Cellular, CCPR and its affiliates will only seek indemnity for losses hereunder
from each Stockholder in proportion to his ownership percentage set forth on the
first page hereof .

     12. Indemnification by Cellular and CCPR. Assignor and each Stockholder
         ------------------------------------                               
shall be indemnified and held harmless by Cellular and CCPR against any and all

 
losses, arising from (a) CCPR's ownership of the Interest; (b) any material
misrepresentation, breach of warranty, or nonperformance of any obligation
hereunder on the part of Cellular or CCPR; (c) any other act or omission on the
part of CCPR or its affiliates in connection with its interest in the
Partnership or (d) arising out of or based upon an untrue statement of fact in
the Registration Statement or arising out of or based upon the omission or
alleged omission to state therein a material fact necessary to make the
statements therein not misleading, other than those arising out of any
Information.

     13. Continuing Effectiveness. Each party's representations shall be true
         ------------------------                                           
and correct, and each party's warranties and indemnifications shall be in full
force and effect on the date that the party executes this Agreement and, to the
extent the same are applicable at Closing, as if made on the date and time of
such Closing. Each party's representations, warranties and indemnifications
shall survive the Closing and shall be fully actionable and enforceable
thereafter. In the event that a party becomes aware of any information,
occurrence or omission which would alter any of its representations or would
impair its ability to perform any of its warranties, indemnifications, or
obligations hereunder, or would possibly lead to any right to indemnification,
then the party shall notify the other party immediately of such information,
occurrence or omission and shall disclose all relevant facts. The other party
shall have the opportunity to defend itself, if necessary, in any resulting
proceeding. The settlement of any such proceeding or threatened proceeding shall
be subject to the other party's prior consent if the other party is to be
subject to any obligation to indemnify against the cost of the settlement.

     14. Expenses. Cellular, CCPR, Assignor and each Stockholder shall each bear
         --------                                                               
their own legal and other fees and expenses associated with the preparation,
execution and consummation of this Agreement and the filing and prosecution of
any required Governmental Agency submissions, provided that CCPR shall pay any
HSR filing fees to the extent applicable. CCPR will bear all costs associated
with the preparation of the Registration Statement except that each Stockholder
shall bear broker's fees or discounts associated with a resale of the Shares
acquired by such Stockholder pursuant hereto.

     15. Termination as of Right. Notwithstanding any other provision herein or
         -----------------------                                              
termination, this Agreement may be terminated, without liability of any kind, at
the option of either Assignor or CCPR, upon written notice to the other if there
is no Closing in accordance with all the terms of this Agreement on or before
March 31, 1996.

     16. Brokers Fees. Each party represents and warrants that it has not
         ------------

transaction.

         -------

to consult with its counsel and other advisors, he and it is prepared to

5. DUTIES OF ESCROW AGENT; DISTRIBUTIONS

- -----------------------------------
     (a) The obligations and duties of the Escrow Agent hereunder are purely 
ministerial and shall be limited to the safekeeping of the Escrow Fund and the

jurisdiction.

8. INTERPLEADER
- ---------------
  Notwithstanding any provisions contained herein to the contrary, in the event

discretion, file an action in interpleader to resolve said disagreement. The

hereof for all costs and attorneys' fees incurred by it in its capacity as

shall jointly appoint a successor escrow agent, who shall assume the duties of 
Escrow Agent hereunder. The Escrow Agent shall immediately deposit all Escrow

10. ADDITIONAL INSTRUCTIONS
- ---------------------------
  The parties hereto at their respective cost and expense shall cooperate with 
and assist the Escrow Agent as reasonably requested by the Escrow Agent in 
connection with the Escrow Agent's performance of its obligations hereunder.

jurisdiction to have discharged any of its duties hereunder in a grossly 
negligent manner or to have been guilty of willful misconduct with regard to any
of its duties hereunder. Except for the Escrow Agent's liability arising from 
its gross negligence or fraud, each of the other parties hereto shall jointly 
and severally indemnify and hold the Escrow Agent harmless from any and all
