NEWS RELEASE:

FOR IMMEDIATE RELEASE:

          OLIVETTI S.p.A. AND MANNESMANN AG ANNOUNCE PLANS TO ACQUIRE 

                   CELLULAR COMMUNICATIONS INTERNATIONAL, INC.

New York, New York, December 11, 1998 -- Cellular Communications  International,
Inc. (NNM:  CCIL),  Olivetti S.p.A.  and Mannesmann AG announced today that they
have signed a definitive merger agreement for Olivetti and Mannesmann to acquire
through  a newly  formed  entity  (Kensington  Acquisition  Sub,  Inc.)  all the
outstanding common stock of CCIL.

Under  the  agreement,  Olivetti  and  Mannesmann  will  commence,  on or before
December  18,  1998,  a  US$65.75  per  share  cash  tender  offer  for  all the
outstanding  shares of common stock of CCIL.  Following the  consummation of the
tender offer,  Olivetti and Mannesmann  will acquire through a merger all shares
not  purchased  in the tender  offer at the same price.  This would result in an
aggregate equity purchase price on a fully diluted basis of approximately US$1.4
billion.

The Board of  Directors of each of the  companies  has approved the tender offer
and  the  related  transactions.  Goldman,  Sachs  & Co.  advised  Olivetti  and
Mannesmann on the transaction. CCIL's Board has determined that the terms of the
tender offer and merger are fair to, and in the best  interests of, CCIL and its
stockholders,  and has recommended that all  stockholders  accept the offer. The
Board of Directors of CCIL has received an opinion from its  financial  advisor,
Wasserstein  Perella & Co., Inc., to the effect that the consideration  proposed
to be paid in the  transaction is fair to CCIL's  stockholders  from a financial
point of view.

The tender offer will be conditioned  upon, among other things,  the tender of a
number of shares which represents a majority of the outstanding shares of common
stock on a fully  diluted  basis.  The  tender  offer  will not be  subject to a
financing contingency.

William Ginsberg, chief executive officer of CCIL, stated, "In 1988, we formed a
relationship with Olivetti,  in order to leverage our U.S.  cellular  experience
and knowledge by means of pursuing  analogous  opportunities in other countries.
We  were   instrumental   in  the  creation  and   subsequent   development   of
Omnitel-Pronto Italia S.p.A., which has evolved into one of the largest and most
rapidly growing cellular  operations in the world.  During this time, the market
value of CCIL has  grown  from  under  $50  million  at the time  CCIL  became a
separate public company in 1991 to approximately $1.4 billion on a fully diluted
basis at the $65.75 per share price announced today."



<PAGE>

"We are pleased to enter into this  transaction with Olivetti and Mannesmann and
to recommend it to stockholders. We also recognize and appreciate the efforts of
the many people who have contributed to CCIL's success."

CCIL's  primary  asset is an  approximate  14.667%  interest in Omnitel  Sistemi
Radiocellulari  Italiani  S.p.A.  (OSR), a strategic joint venture which holds a
70%  interest in  Omnitel-Pronto  Italia  S.p.A.  (Omnitel).  Omnitel is Italy's
second leading mobile operator with over 5.0 million subscribers.

In the autumn of 1997,  Olivetti and Mannesmann  formed a joint venture,  Oliman
Holding B.V., to cooperate in the area of  telecommunications  in Italy with the
objective  to expand  their  leading  position  as a private  competitor  in the
Italian  telecommunications market. Olivetti currently holds a 62.5% interest in
Oliman and Mannesmann holds a 37.5% interest. Mannesmann will raise its stake in
Oliman  to 49.9% by  February  1999.  Oliman  currently  holds an  indirect  40%
interest in Omnitel and a 100% stake in the fixed line operator Infostrada. With
this  acquisition,  Oliman will  further  strengthen  its  majority  position in
Omnitel.  CCIL  currently  holds an  indirect  stake of  approximately  10.3% in
Omnitel.

Mannesmann operates in Telecommunications,  Engineering,  Automotive and Tubes &
Trading and generated sales of around DM 39 billion in 1997. The Group is one of
the leading alternative  telecommunication operators in the recently liberalized
European market.

The  Olivetti  Group  is  a  leading   international  player  operating  through
subsidiaries and affiliates in the telecommunications and information technology
sectors.  In  telecommunications,  Olivetti  operates  both in the  wireless and
wireline   markets  through  Omnitel  and  Infostrada,   respectively.   In  the
Information  Technology  sector,  Olivetti wholly owns Olivetti  Lexikon,  which
specializes in I.T.  products for the office and the consumer  markets.  It also
has a 18.5% ownership in Wang Global, a United States publicly traded company.

Conference Call: A telephone  conference call will be held at 2:00 p.m. New York
time today to discuss this  transaction.  Persons wishing to participate in this
call can do so by calling the following numbers:

U.S. callers:              (800) 865-4460

"Agreement"),  between Cellular Communications  International,  Inc., a Delaware
corporation  (the "Company"),  and Kensington  Acquisition Sub, Inc., a Delaware
corporation (the "Purchaser").

                               W I T N E S S E T H

     WHEREAS,  the Boards of Directors of each of the Company and the  Purchaser
have  determined  that  it  is  in  the  best  interests  of  their   respective
stockholders for the Purchaser to acquire the Company upon the terms and subject
to the conditions set forth herein; and

     WHEREAS,  in  furtherance  thereof,  it is proposed that the Purchaser will
make a cash tender offer (the  "Offer") to acquire all shares (the  "Shares") of
the issued  and  outstanding  common  stock,  par value  $.01 per share,  of the
Company  ("Company  Common  Stock"),  including the associated  Preferred  Stock
Purchase Rights (the "Rights") issued pursuant to the Rights Agreement, dated as
of December 19, 1990,  between the Company and Continental  Stock Transfer Trust
Company (the "Rights  Agreement"),  for $65.75 per Share (the "Offer Price"), or
such higher price as may be paid in the Offer, in each case net to the seller in
cash;

     WHEREAS,  also in furtherance of such acquisition,  the Boards of Directors
of the Company and the Purchaser have each approved the merger (the "Merger") of
the Purchaser with and into the Company  following the Offer in accordance  with
the General  Corporation Law of the State of Delaware  ("Delaware Law") and upon
the terms and subject to the conditions set forth herein;

     WHEREAS,  the Board of Directors of the Company (the "Board of  Directors")
has unanimously approved this Agreement and has resolved to recommend acceptance
of the Offer and the Merger to the holders of the Shares;

     WHEREAS,  as a condition and inducement to the Purchaser to enter into this
Agreement and to incur the obligations set forth herein,  concurrently  with the
execution  and delivery of this  Agreement,  the  Purchaser  and the Company are
entering  into an Option  Agreement in the form of Exhibit A hereto (the "Option
Agreement"),  pursuant to which, among other things, the Company has granted the
Purchaser an option to purchase  certain  newly-issued  shares of Company Common
Stock subject to certain conditions; and

     WHEREAS,  as a condition and inducement to the Purchaser to enter into this
Agreement,  the Board of  Directors  has  approved  the terms of a  Stockholders
Agreement in the form of Exhibit B hereto (the  "Stockholders  Agreement") to be

<PAGE>


into by the  Purchaser,  the Company,  and the  directors,  officers and certain
stockholders of the Company  concurrently  with the execution of this Agreement,
pursuant  to which each such  Person (as  defined  below) has agreed to vote its
Shares for approval of the Merger and this Agreement.

     NOW,   THEREFORE,   in  consideration  of  the  foregoing  and  the  mutual
representations,  warranties,  covenants and agreements  herein  contained,  and
intending to be legally bound hereby, the Company and the Purchaser hereby agree
as follows:

                                   ARTICLE I.

                                THE TENDER OFFER

     SECTION 1.1. The Offer.

     (a)  Provided  that  this  Agreement  shall  not have  been  terminated  in
accordance  with  Section 8.1 hereof and none of the events set forth in Annex I
hereto  shall  have  occurred  and be  existing,  the  Purchaser  or a direct or
indirect  subsidiary  thereof shall  commence  (within the meaning of Rule 14d-2
under the Securities Exchange Act of 1934, as amended (the "Exchange Act"),) the
Offer as promptly as practicable,  but in no event later than five business days
following the execution of this  Agreement.  The  obligation of the Purchaser to
accept for payment any Shares  tendered shall be subject to the  satisfaction of
only those conditions set forth in Annex I. The Purchaser expressly reserves the
right to waive any such  condition  or to increase  the Offer  Price.  The Offer
Price shall be net to the seller in cash. The Company agrees that no Shares held
by the Company will be tendered pursuant to the Offer.

     (b) Without the prior written  consent of the Company,  the Purchaser shall
not (i) decrease the Offer Price or change the form of consideration  payable in
the Offer,  (ii)  decrease  the number of Shares  sought,  (iii)  amend or waive
satisfaction  of the  Minimum  Condition  (as defined in Annex I) or (iv) impose
additional  conditions  to the Offer or amend any other term of the Offer in any
manner  adverse  to the  holders  of Shares;  provided  however,  that if on the
initial  scheduled  expiration date of the Offer (the  "Expiration  Date") which
shall be twenty (20) business  days after the date the Offer is  commenced,  all
conditions to the Offer shall not have been  satisfied or waived,  the Purchaser
may, from time to time, in its sole discretion,  extend the expiration date (any
such  extension to be for ten (10)  business days or less);  provided,  however,
that the expiration  date of the Offer may not be extended  beyond May 15, 1999.
The  Purchaser  shall,  on the terms and  subject to the prior  satisfaction  or
waiver of the conditions of the Offer, accept for payment and purchase,  as soon
as practicable  after the expiration of the Offer,  all Shares validly  tendered
and not withdrawn prior to the expiration of the Offer; provided,  however, that
the  Purchaser  may (i)  extend  the  Expiration  Date  (including  as it may be
extended) for up to ten

                                       2
<PAGE>


(10)  business days in connection  with an increase in the  consideration  to be
paid pursuant to the Offer so as to comply with applicable rules and regulations
of the Securities and Exchange  Commission (the "SEC"), and (ii) if, immediately
prior to the Expiration  Date (as it may be extended),  the Shares  tendered and
not  withdrawn  pursuant  to the Offer  equal  less than 90% of the  outstanding
Shares,  the Purchaser  may extend the Offer for a period not to exceed  fifteen
(15)  business  days,  notwithstanding  that all  conditions  to the  Offer  are
satisfied as of such Expiration Date;  provided,  however,  that during any such
extension of the Offer, the Purchaser  irrevocably  waives all of the conditions
to the Offer set forth in Annex I (other than the Minimum  Condition (as defined
in Annex I)). It is agreed that the conditions to the Offer set forth in Annex I
are for the  benefit  of the  Purchaser  and may be  asserted  by the  Purchaser
regardless  of the  circumstances  giving rise to any such  condition or, except
with respect to the Minimum Condition,  may be waived by the Purchaser, in whole
or in part at any time and from time to time, in its sole discretion.

     (c) The Offer shall be made by means of an offer to purchase (the "Offer to
Purchase")  having only the conditions set forth in Annex I hereto.  On the date
the Offer is  commenced,  the  Purchaser  shall file with the SEC a Tender Offer
Statement  on Schedule  14D-1  (together  with all  amendments  and  supplements
thereto, and including the exhibits thereto, the "Schedule 14D-1"). The Schedule
14D-1 will contain  (including  as an exhibit) or  incorporate  by reference the
Offer to Purchase  and forms of the related  letter of  transmittal  and summary
advertisement  (which  documents,  together with any  supplements  or amendments
thereto,  and any other SEC schedule or form which is filed in  connection  with
the Offer and related  transactions,  are referred to collectively herein as the
"Offer  Documents").  The Offer  Documents will comply in all material  respects
with the provisions of applicable Federal securities laws and, on the date filed
with the SEC and on the date first  published,  mailed or given to the Company's
stockholders,  shall not contain any untrue statement of a material fact or omit
to state any material fact  required to be stated  therein or necessary in order
to make the statements  therein,  in light of the circumstances under which they
were  made,  not  misleading,  except  that  no  representation  is  made by the
Purchaser with respect to information furnished by the Company to the Purchaser,
in writing,  expressly for  inclusion in the Offer  Documents.  The  information
supplied by the Company to the Purchaser, in writing, expressly for inclusion in
the Schedule  14D-1 will not contain any untrue  statement of a material fact or
omit to state any material  fact  required to be stated  therein or necessary in
order to make the statements  therein, in light of the circumstances under which
they were made, not misleading.

     (d) The Purchaser  agrees to take all steps necessary to cause the Schedule
14D-1 to be filed with the SEC and the Offer  Documents  to be  disseminated  to
holders of  Shares,  in each

                                       3
<PAGE>


case as and to the extent required by applicable  Federal  securities  laws. The
Company and its counsel  shall be given a reasonable  opportunity  to review and
comment on any Offer  Documents  before they are filed with the SEC. Each of the
Purchaser  and the  Company  agrees  promptly  (i) to  correct  any  information
provided by it for use in the  Schedule  14D-1 or the Offer  Documents if and to
the extent that such  information  shall have become false or  misleading in any
material  respect  and  (ii)  to  supplement  the  information  provided  by  it
specifically for use in the Schedule 14D-1 or the Offer Documents to include any
information that shall become necessary in order to make the statements therein,
in light of the  circumstances  under which they were made, not misleading.  The
Purchaser further agrees to take all steps necessary to cause the Schedule 14D-1
as so corrected to be filed with the SEC and to be disseminated to the Company's
stockholders,  in each case as and to the extent required by applicable  Federal
securities  laws. In addition,  the Purchaser  agrees to provide the Company and
its counsel with any comments,  whether  written or oral,  that the Purchaser or
its counsel may receive from time to time from the SEC or its staff with respect
to the Schedule 14D-1 promptly after the receipt of such comments.

     (e) The  Purchaser  shall  have  available  on a  timely  basis  the  funds
necessary  to accept for  payment,  and pay for,  any Shares that the  Purchaser
becomes  obligated  to pay for  pursuant  to the Offer or pursuant to Article II
hereof.

     SECTION 1.2. Company Action.

     (a) The Company hereby approves of and consents to the Offer and represents
and warrants that:

          (i) the Board of  Directors,  at a  meeting  duly  called  and held on
     December 10, 1998, at which a majority of the Directors were present:  duly
     and unanimously approved and adopted this Agreement,  the Option Agreement,
     the  Stockholders  Agreement and the transactions  contemplated  hereby and
     thereby, including the Offer and the Merger, resolved to recommend that the
     stockholders of the Company accept the Offer,  tender their Shares pursuant
     to the Offer and approve this Agreement and the  transactions  contemplated
     hereby,  including the Merger;  and determined  that this Agreement and the
     transactions  contemplated hereby,  including the Offer and the Merger, are
     fair to and in the best  interests  of the  holders  of  Shares;  provided,
     however,  that prior to the purchase by the Purchaser of Shares pursuant to
     the Offer, the Company may modify,  withdraw or change such  recommendation
     to the extent that the Board of Directors  determines,  after  consultation
     with outside legal counsel to the Company, that the failure to so withdraw,
     modify or change such  recommendation  would  likely  breach the  fiduciary
     duties of the Board of Directors under applicable laws;

                                       4
<PAGE>

          (ii) with  respect  to the  Rights  Agreement,  the  Company  has duly
     amended the Rights Agreement to provide that (A) neither this Agreement nor
     any of the transactions  contemplated  hereby,  including the Offer and the
     Merger,  will result in the  occurrence of a  "Distribution  Date" (as such
     term is defined in the Rights  Agreement) or otherwise  cause the Rights to
     become  exercisable  by the  holders  thereof,  and  (B) the  Rights  shall
     automatically  on and as of the Effective  Time (as defined  below) be void
     and of no further force or effect; and

          (iii)  Wasserstein  Perella & Co.,  Inc.  ("Wasserstein  Perella") has
     delivered to the Board of Directors its written opinion that as of the date
     hereof the  consideration to be received by the stockholders of the Company
     pursuant to each of the Offer and the Merger is fair to the stockholders of
     the Company from a financial point of view. The Company has been authorized
     by Wasserstein Perella to permit the inclusion of such fairness opinion (or
     a  reference  thereto) in the Offer  Documents  and in the  Schedule  14D-9
     referred to below.  The Company  hereby  consents to the  inclusion  in the
     Offer Documents of the  recommendations of the Board of Directors described
     in this Section 1.2(a).

     (b) The Company  shall file with the SEC, no later than the fifth  business
day  following  the  public  announcement  of this  Agreement,  a  Tender  Offer
Solicitation/Recommendation  Statement on Schedule 14D-9  (together with any and
all amendments or supplements  thereto,  and including the exhibits thereto, the
"Schedule 14D-9").  The Schedule 14D-9 will comply in all material respects with
the provisions of all applicable law,  including Federal  securities law and, on
the date filed with the SEC and on the date  first  published,  sent or given to
the Company's stockholders, shall not contain any untrue statement of a material
fact or omit to state  any  material  fact  required  to be  stated  therein  or
necessary in order to make the statements therein, in light of the circumstances
under which they were made, not  misleading,  except that no  representation  is
made by the Company with respect to information  furnished by the Purchaser,  in
writing,  expressly for  inclusion in the Schedule  14D-9.  The Company  further
agrees to take all steps  necessary to cause the Schedule 14D-9 to be filed with
the SEC and to be disseminated to holders of the Shares,  in each case as and to
the extent  required by applicable  Federal  securities  laws. The Company shall
mail, or cause to be mailed,  such  Schedule  14D-9 to the  stockholders  of the
Company  at  the  same  time  the  Offer  Documents  are  first  mailed  to  the
stockholders  of the Company  together with such Offer  Documents.  The Schedule
14D-9 and the Offer Documents shall contain the  recommendations of the Board of
Directors  described in Section  1.2(a) hereof.  The Company agrees  promptly to
correct the Schedule  14D-9 if and to the extent that it shall have become false
or  misleading  in any  material  respect  (and the  Purchaser,  with respect to
written  information  supplied

                                       5
<PAGE>


by it  specifically  for use in the Schedule  14D-9,  shall promptly  notify the
Company of any required  corrections of such  information and cooperate with the
Company with respect to  correcting  such  information)  and to  supplement  the
information  contained in the  Schedule  14D-9 to include any  information  that
shall become necessary in order to make the statements  therein, in light of the
circumstances  under which they were made, not  misleading.  The Company further
agrees to take all steps  necessary to cause the Schedule  14D-9 as so corrected
to be  filed  with the SEC and to be  disseminated  to the  stockholders  of the
Company, in each case as and to the extent required by applicable law, including
Federal  securities  laws.  The  Purchaser  and its  counsel  shall  be  given a
reasonable  opportunity to review and comment on the Schedule 14D-9 before it is
filed with the SEC. In addition, the Company agrees to provide the Purchaser and
its counsel with any comments,  whether written or oral, that the Company or its
counsel may receive  from time to time from the SEC or its staff with respect to
the Schedule 14D-9 promptly after the receipt of such comments.

     (c) In connection with the Offer,  the Company,  promptly upon execution of
this Agreement,  shall furnish or cause to be furnished to the Purchaser mailing
labels  containing  the names and  addresses  of all  record  holders of Shares,
non-objecting  beneficial owner lists and security  position  listings of Shares
held in stock depositories, each as of a recent date, and shall promptly furnish
the Purchaser with such additional information  (including,  but not limited to,
updated lists and computer files  containing the names of stockholders and their
addresses,  mailing  labels  and  security  position  listings)  and such  other
information and assistance as the Purchaser or its agents may reasonably request
for the purpose of communicating the Offer to the record and beneficial  holders
of Shares.

     SECTION 1.3. Directors.

     (a) Promptly upon the purchase by the  Purchaser of any Shares  pursuant to
the  Offer,  and from time to time  thereafter  as Shares  are  acquired  by the
Purchaser,  the  Purchaser  shall  be  entitled  to  designate  such  number  of
directors,  rounded up to the next whole  number,  on the Board of  Directors as
will  give the  Purchaser,  subject  to  compliance  with  Section  14(f) of the
Exchange Act and Rule 14f-1 promulgated thereunder,  representation on the Board
of Directors equal to at least that number of directors which equals the product
of the total number of directors on the Board of Directors (giving effect to the
directors  appointed or elected pursuant to this sentence and including  current
directors serving as officers of the Company)  multiplied by the percentage that
the  aggregate  number  of Shares  beneficially  owned by the  Purchaser  or any
affiliate  of the  Purchaser  (including  for  purposes of this Section 1.3 such
Shares as are accepted for payment  pursuant to the Offer,  but excluding Shares
held by the Company and excluding Shares  beneficially owned by the Purchaser by
virtue of the Option  Agreement) bears

                                       6
<PAGE>


to the number of Shares outstanding.  At such times, the Company will also cause
each  committee of the Board of Directors to include  Persons  designated by the
Purchaser  constituting  at least the same  percentage of each such committee or
board as the  Purchaser's  designees are of the Board of Directors.  The Company
shall, upon request by the Purchaser, promptly increase the size of the Board of
Directors or exercise its best efforts to secure the resignations of such number
of incumbent directors as is necessary to enable the Purchaser's designees to be
elected to the Board of Directors in  accordance  with the terms of this Section
1.3 and shall  cause  the  Purchaser's  designees  to be so  elected;  provided,
however,  that,  in the event that the  Purchaser's  designees  are appointed or
elected to the Board of Directors,  until the Effective  Time (as defined below)
the Board of Directors shall have at least one director who is a director on the
date  hereof  and who is  neither an  officer  of the  Company  nor a  designee,
stockholder,   affiliate  or  associate  (within  the  meaning  of  the  Federal
securities  laws)  of  the  Purchaser  (one  or  more  of  such  directors,  the
"Independent  Directors");  provided,  further, that if no Independent Directors
remain,  the  other  directors  shall  designate  one  Person to fill one of the
vacancies  who shall not be either an  officer  of the  Company  or a  designee,
stockholder,  affiliate or associate of the Purchaser,  and such Person shall be
deemed to be an Independent Director for purposes of this Agreement.

     (b) Subject to applicable  law, the Company shall  promptly take all action
necessary  pursuant  to  Section  14(f)  of the  Exchange  Act  and  Rule  14f-1
promulgated  thereunder in order to fulfill its  obligations  under this Section
1.3 and shall  include in the  Schedule  14D-9 mailed to  stockholders  promptly
after the  commencement of the Offer (or an amendment  thereof or an information
statement pursuant to Rule 14f-1 if the Purchaser has not theretofore designated
directors)  such  information  with  respect to the Company and its officers and
directors as is required  under Section 14(f) and Rule 14f-1 in order to fulfill
its  obligations  under this Section 1.3. The Purchaser  will supply the Company
and be solely  responsible  for any  information  with respect to itself and its
nominees,  officers, directors and affiliates required by Section 14(f) and Rule
14f-1.  Notwithstanding anything in this Agreement to the contrary, in the event
that the Purchaser's designees are elected to the Board of Directors,  after the
acceptance for payment and purchase of Shares pursuant to the Offer and prior to
the  Effective  Time,  the  affirmative  vote of a majority  of the  Independent
Directors  shall be required to (i) amend or terminate  this Agreement on behalf
of the Company,  (ii) exercise or waive any of the Company's  rights or remedies
hereunder,  (iii) extend the time for performance of the Purchaser's obligations
hereunder or (iv) take any other action by the Company in  connection  with this
Agreement required to be taken by the Board of Directors.

     statement  relating  to the  Merger  and  this  Agreement  and use its best
     efforts (x) to obtain and

                                       9
<PAGE>


     furnish  the  information  required  to be included by the SEC in the Proxy
     Statement (as defined below) and, after consultation with the Purchaser, to
     respond  promptly  to any  comments  made by the SEC  with  respect  to the
     preliminary proxy or information  statement and cause a definitive proxy or
     information  statement,  including any amendment or supplement thereto (the
     "Proxy  Statement"),  to be mailed to its  stockholders,  provided  that no
     amendment or supplement to the Proxy  Statement will be made by the Company
     without  consultation  with the Purchaser and its counsel and (y) to obtain
     the  necessary   approvals  of  the  Merger  and  this   Agreement  by  its
     stockholders; and

          (iii) notwithstanding the provisions of Section 2.7(a)(ii)(y),  unless
     the Board of Directors,  after  consultation  with outside legal counsel to
     the Company,  determines  that to do so would likely  breach the  fiduciary
     duties of the Board of Directors under applicable law, include in the Proxy
     Statement the recommendation of the Board of Directors that stockholders of
     the Company vote in favor of the approval of the Merger and the adoption of
     this Agreement.

     (b) The Purchaser shall vote, or cause to be voted,  all of the Shares then
owned by it or any of its  subsidiaries  and affiliates in favor of the approval
of the Merger and the adoption of this Agreement.

     SECTION  2.8.  Merger  Without  Meeting  of  Stockholders.  Notwithstanding
Section 2.7 hereof,  in the event that the  Purchaser or any  subsidiary  of the
Purchaser shall acquire at least 90% of the outstanding Shares,  pursuant to the
Offer or otherwise,  the parties  hereto shall,  at the request of the Purchaser
and subject to Article VII hereof,  take all necessary and appropriate action to
cause  the  Merger  to  become  effective  as soon  as  practicable  after  such
acquisition,  without a meeting of  stockholders  of the Company,  in accordance
with Section 253 of Delaware Law.

     SECTION 2.9. Conversion of Securities.  At the Effective Time, by virtue of
the Merger and without any action on the part of the  Purchaser,  the Company or
the holder of any of the following securities:

     (a) Each Share issued and outstanding immediately before the Effective Time
(other  than any  Shares to be  cancelled  pursuant  to  Section  2.9(b) and any
Dissenting  Shares (as  defined  in  Section  2.10(a))  shall be  cancelled  and
extinguished  and be converted into the right to receive the Offer Price in cash
payable to the holder thereof,  without  interest (the "Merger  Consideration"),
upon surrender of the certificate formerly representing such Share in the manner
provided in Section 2.11 hereof.  All such Shares,  when so converted,  shall no
longer be outstanding and shall automatically be cancelled and retired and 

                                       10
<PAGE>


shall cease to exist,  and each holder of a  certificate  representing  any such
Shares shall cease to have any rights with respect thereto,  except the right to
receive the Merger Consideration therefor upon the surrender of such certificate
in accordance with Section 2.11 hereof, without interest.

     (b) Each Share held in the  treasury of the Company and each Share owned by
the Purchaser or any direct or indirect wholly owned subsidiary of the Purchaser
immediately before the Effective Time shall be cancelled and extinguished and no
payment or other consideration shall be made with respect thereto.

     (c) Each share of common stock,  par value $.01 per share, of the Purchaser
issued and outstanding  immediately  before the Effective Time shall  thereafter
represent  one  validly  issued,  fully paid and  nonassessable  share of common
stock, par value $.01 per share, of the Surviving Corporation.

     SECTION 2.10. Dissenting Shares.

     (a)  Notwithstanding  any provision of this Agreement to the contrary,  any
Shares held by a holder who has demanded and  perfected his demand for appraisal
of his Shares in  accordance  with  Delaware Law  (including  but not limited to
Section  262  thereof)  and as of the  Effective  Time has  neither  effectively
withdrawn nor lost his right to such appraisal ("Dissenting Shares"),  shall not
be  converted  into or represent  the right to receive the Merger  Consideration
pursuant to Section 2.9, but the holder  thereof  shall be entitled to only such
rights as are granted by Delaware Law.

     (b)  Notwithstanding  the  provisions of Section  2.7(a),  if any holder of
Shares who demands  appraisal of his Shares under Delaware Law shall effectively
withdraw  or lose  (through  failure  to  perfect  or  otherwise)  his  right to
appraisal,  then as of the  Effective  Time  or the  occurrence  of such  event,
whichever later occurs,  such holder's Shares shall  automatically  be converted
into and  represent  only the  right to  receive  the  Merger  Consideration  as
provided in Section  2.9(a),  without  interest  thereon,  upon surrender of the
certificate or  certificates  representing  such Shares pursuant to Section 2.11
hereof.

     (c) The Company  shall give the  Purchaser (i) prompt notice of any written
demands for appraisal or payment of the fair value of any Shares, withdrawals of
such demands, and any other instruments served pursuant to Delaware Law received
by the  Company  and  (ii)  the  opportunity  to  direct  all  negotiations  and
proceedings  with  respect to demands for  appraisal  under  Delaware  Law.  The
Company shall not  voluntarily  make any payment with respect to any demands for
appraisal and shall not, except with the prior written consent of the Purchaser,
settle or offer to settle any such demands.

                                       11

     SECTION 2.11. Surrender of Shares; Stock Transfer Books.

     (a) Before the  Effective  Time,  the Purchaser  shall  designate a bank or
trust  company  reasonably  acceptable  to the  Company  to act as agent for the
holders  of Shares in  connection  with the  Merger  (the  "Exchange  Agent") to
receive the funds necessary to make the payments contemplated by Section 2.9. At
the Effective  Time, the Purchaser shall deposit,  or cause to be deposited,  in
trust with the Exchange Agent for the benefit of holders of Shares the aggregate
consideration  to which such  holders  shall be entitled at the  Effective  Time
pursuant to Section 2.9.

     (b) Each holder of certificates  representing any Shares cancelled upon the
Merger,  which immediately  prior to the Effective Time represented  outstanding
Shares (the  "Certificates")  whose  Shares were  converted  pursuant to Section
2.9(a),  may  thereafter  surrender  such  Certificate  or  Certificates  to the
Exchange  Agent,  as agent for such  holder,  to effect  the  surrender  of such
Certificate or Certificates on such holder's behalf for a period ending one year
after the Effective Time. The Purchaser agrees that promptly after the Effective
Time it shall  cause the  distribution  to holders of record of Shares as of the
Effective Time of appropriate  materials to facilitate such surrender.  Upon the
surrender of  Certificates,  the Purchaser shall cause the Exchange Agent to pay
the holder of such  Certificates in exchange therefor cash in an amount equal to
the Merger Consideration  multiplied by the number of Shares represented by such
Certificate.  Until so surrendered,  each Certificate  (other than  Certificates
representing Dissenting Shares and Certificates  representing Shares held by the
Purchaser or any direct or indirect wholly owned  subsidiary of the Purchaser or
in the treasury of the Company) shall represent  solely the right to receive the
aggregate Merger Consideration relating thereto.

     (c) If payment of the Merger  Consideration  in respect of cancelled Shares
is to be made to a Person  other  than the  Person in whose  name a  surrendered
Certificate or instrument is registered, it shall be a condition to such payment
that the Certificate or instrument so surrendered  shall be properly endorsed or
shall be otherwise  in proper form for  transfer and that the Person  requesting
such payment shall have paid any transfer and other taxes  required by reason of
such  payment  in a name  other  than  that  of  the  registered  holder  of the
Certificate  or  instrument   surrendered  or  shall  have  established  to  the
satisfaction  of the  Purchaser or the  Exchange  Agent that such tax either has
been paid or is not applicable.

     (d) At the Effective Time, the stock transfer books of the Company shall be
closed and there shall not be any further registration of transfers of Shares or
any shares of capital stock  thereafter on the records of the Company.  From and
after

                                       12
<PAGE>


the Effective  Time,  the holders of  certificates  evidencing  ownership of the
Shares  outstanding  immediately prior to the Effective Time shall cease to have
any rights with respect to such Shares,  except as otherwise provided for herein
or by applicable law. If, after the Effective Time,  Certificates  are presented
to the  Surviving  Corporation,  they shall be cancelled  and  exchanged for the
Merger Consideration as provided in this Article II. No interest shall accrue or
be paid on any cash payable upon the surrender of a Certificate or  Certificates
which immediately before the Effective Time represented outstanding Shares.

     (e) Promptly following the date which is one year after the Effective Time,
the  Surviving  Corporation  shall be entitled to require the Exchange  Agent to
deliver to it any cash (including any interest  received with respect  thereto),
Certificates and other documents in its possession  relating to the transactions
contemplated  hereby,  which had been made  available to the Exchange  Agent and
which have not been disbursed to holders of  Certificates,  and thereafter  such
holders  shall be  entitled  to look to the  Surviving  Corporation  (subject to
abandoned  property,  escheat or similar laws) only as general creditors thereof
with respect to the Merger  Consideration  payable  upon due  surrender of their
Certificates,  without any  interest  thereon.  Notwithstanding  the  foregoing,
neither the Surviving  Corporation nor the Exchange Agent shall be liable to any
holder of a Certificate for Merger Consideration  delivered to a public official
pursuant to any applicable abandoned property, escheat or similar law.

     (f) The Merger  Consideration paid in the Merger shall be net to the holder
of Shares in cash,  subject to reduction only for any applicable  Federal backup
withholding or, as set forth in Section 2.8(c),  stock transfer taxes payable by
such holder.

     SECTION 2.12. Stock Plans.

     (a) The Company  shall take all actions  necessary to provide  that, at the
Effective Time, (i) each then  outstanding  option to purchase shares of Company
Common Stock (the  "Options")  granted under any of the  Company's  stock option
plans  referred  to in Section 4.2 hereof,  each as amended  (collectively,  the
"Option Plans"),  whether or not then exercisable or vested,  shall be cancelled
and (ii) in  consideration of such  cancellation,  such holders of Options shall
receive  for each  Share  subject  to such  Option  an  amount  (subject  to any
applicable  withholding tax) in cash equal to the product of (A) the excess,  if
any, of the Offer Price over the per share exercise price of such Option and (B)
the number of Shares  subject to such Option (such amount being herein  referred
to as the "Option Price"); provided,  however, that the Company shall obtain all
necessary  consents or releases from holders of Options to effect the foregoing.
Upon receipt of the Option Price,  the Option shall be cancelled.  The surrender
of an Option to the Company  shall be deemed a release of any and

                                       13
<PAGE>


all rights the holder had or may have had in respect of such Option. As promptly
as practicable  following the  consummation  of the Merger,  the Purchaser shall
provide the Company with the funds  necessary to satisfy its  obligations  under
this Section 2.12(a).

     (b) Except as provided herein or as otherwise  agreed to by the parties and
to the extent  permitted by the Option  Plans,  (i) the Company  shall cause the
Option  Plans to terminate as of the  Effective  Time and shall  provide for the
payment of any  benefit due under such  Option  Plans in cash;  (ii) the Company
shall cause the  provisions  in any other plan,  program or  arrangement,  which
currently  provides  or  previously  provided  for the  issuance or grant by the
Company of any interest in respect of the capital  stock of the Company,  or for
payments based on the value of the capital stock of the Company (each such other
plan  being  referred  to as an  "Other  Stock  Plan")  to  terminate  as of the
Effective  Time and shall  provide for the payment of any benefit due under such
plans in cash;  and (iii) the Company shall take all action  necessary to ensure
that following the Effective Time no holder of Options or any participant in the
Option  Plans or in any Other  Stock  Plan shall  have any right  thereunder  to
acquire any equity securities of the Company,  the Surviving  Corporation or any
subsidiary thereof,  and to terminate all such plans. The Purchaser shall assure
that the  Company has the funds  necessary  to meet its  obligations  under this
Section 2.12(b).

     Except as set forth on the Disclosure  Schedule  delivered to the Purchaser
prior to the  execution  of this  Agreement  (the  "Disclosure  Schedule"),  the
Company hereby represents and warrants to the Purchaser as follows:

     SECTION 4.1. Organization and Qualification; Subsidiaries. The Company is a

of the State of Delaware and has the requisite corporate power and authority and
any necessary  governmental  approvals to own,  operate or lease the  properties
that it purports to own,  operate or lease and to carry on its business as it is
now  being  conducted,  and is duly  qualified  as a foreign  corporation  to do
business,  and is in good standing,  in each jurisdiction where the character of
its properties  owned,  operated or leased or the nature of its activities makes
such qualification necessary, except for such failure which, when taken together
with all other  such  failures,  would not have a  Material  Adverse  Effect (as
defined below).  Except as disclosed on Schedule 4.1 of the Disclosure Schedule,
the Company does not own any  Subsidiaries and does not otherwise have an equity
interest in any other  Person.  The  Subsidiaries  listed on Schedule 4.1 do not

entity of which the Company  (either alone or through or together with any other
Subsidiary) owns, directly or indirectly,  more than 50% of the capital stock or
other equity  interests the holders of which are generally  entitled to vote for
the  election  of the  board  of  directors  or  other  governing  body  of such
corporation or other legal entity.  The term "Material Adverse Effect" means any

regulatory changes generally applicable to cellular operators in Europe or Italy
(including,  without  limitation,  the  issuance  of a fourth  Italian  cellular
license or rules with respect to interconnections or pricing for incoming calls)
or a result of this  Agreement  that is or could  reasonably  be  expected to be
materially  adverse  to (x)  the  business,  operations,  properties  (including
intangible   properties),   condition  (financial  or  otherwise),   results  of
operations,  assets, liabilities,  regulatory status or prospects of the Company

Agreement or the Option Agreement.

consists of 75,000,000  shares of Company  Common Stock and 2,500,000  shares of
Preferred Stock, $.01 par value per share ("Company Preferred Stock"), 1,000,000

be issued  pursuant  to the  exercise  or  conversion  of  outstanding  Options,
Warrants and Voting Debt will be, when issued in accordance  with the respective
terms thereof, duly authorized, validly issued, fully paid and nonassessable and
free of preemptive or similar rights. Except as disclosed on Schedule 4.2 of the
Disclosure Schedule, there are no bonds, debentures, notes or other indebtedness
having general voting rights (or convertible into securities having such rights)
("Voting  Debt") of the  Company  issued  and  outstanding.  There are no voting
trusts or other  agreements  or  understandings  to which the Company is a party
with  respect  to the  voting of the  capital  stock of the  Company.  Except as

arrangements or commitments of any character relating to the issued, unissued or
treasury  shares of the capital stock or any other  interest in the ownership or
earnings of the Company or other security of the Company  obligating the Company
to issue or sell any shares of capital  stock or Voting Debt of, or other equity
interests in, the Company. Except as disclosed on Schedule 4.2 of the Disclosure
Schedule, there are no outstanding contractual obligations of the Company or any
of its  Subsidiaries  to repurchase,  redeem or otherwise  acquire any shares of

the form of a loan, capital contribution or otherwise) in any other entity.

     SECTION 4.3. Authority Relative to this Agreement; Company Action.

     (a) The Company has the  necessary  corporate  power and authority to enter
into this Agreement,  the Option Agreement and the  Stockholders  Agreement and,
subject to obtaining any necessary  stockholder approval of the Merger, to carry
out its obligations hereunder and thereunder. The execution and delivery of this
Agreement by the Company and the consummation by the Company of the transactions
contemplated  by this  Agreement,  the  Option  Agreement  and the  Stockholders
Agreement  have been duly  authorized by all necessary  corporate  action on the
part of the Company, subject to the approval, if necessary, of the Merger by the
Company's  stockholders in accordance with Delaware Law. Each of this Agreement,
the Option Agreement and the  Stockholders  Agreement has been duly executed and
delivered by the Company and,  assuming due and valid  authorization,  execution
and delivery hereof and thereof by the other parties hereto and thereto, each of
this Agreement and the  Stockholders  Agreement  constitutes a legal,  valid and
binding obligation of the Company, enforceable against it in accordance with its
terms.

     (b) The  Company  has taken all  action  which may be  necessary  under the
Rights  Agreement,  so that (i) the  execution  of this  Agreement,  the  Option
Agreement and the Stockholders  Agreement and any amendments  hereto and thereto
by the  parties  hereto and  thereto and the  consummation  of the  transactions
contemplated  hereby and thereby  shall not cause (A) the Purchaser to become an
Acquiring  Person (as  defined in the Rights  Agreement)  or (B) a  Distribution
Date, a Stock  Acquisition Date or a Triggering Event (as such terms are defined
in the Rights Agreement) to occur, irrespective of the number of Shares acquired
pursuant  to the Offer or  exercise  of the  option  granted  under  the  Option
Agreement, and (ii) the Rights (as defined in the Rights Agreement) shall expire
upon the acceptance of Shares for payment pursuant to the Offer.

     (c) The  Board  of  Directors  has  approved  this  Agreement,  the  Option
Agreement,  the Stockholders Agreement and the transactions  contemplated hereby
and thereby  (including but

                                       18
<PAGE>


not limited to the Offer,  the Merger and the matters provided for in the Option
Agreement)  so as to render  inapplicable  hereto and thereto the  limitation on
business  combinations  contained  in (i) Section  203 of  Delaware  Law (or any
similar  provision)  and (ii)  Article  Ninth  of the  Restated  Certificate  of
Incorporation of the Company. As a result, the only vote of holders of any class
or series of the capital stock of the Company  required to adopt this  Agreement
and  the  transactions   contemplated  hereby,  including  the  Merger,  is  the
affirmative vote of a majority of the outstanding  Shares, and if Section 253 of
Delaware Law is applicable to the Merger, no such vote will be required. Neither
Section  203 of  Delaware  Law nor any other  state  takeover  or control  share
statute or similar  statute or  regulation  applies or  purports to apply to the
Offer, the Merger or any of the transactions contemplated hereby or thereby.

     SECTION 4.4. No Conflict; Required Filings and Consents.

     (a) Except as disclosed on Schedule 4.4 of the Disclosure Schedule,  to the
Company's  knowledge,  the execution and delivery of this Agreement,  the Option
Agreement  and  the  Stockholders  Agreement  by the  Company  do  not,  and the
performance  of this  Agreement,  the  Option  Agreement  and  the  Stockholders
Agreement by the Company will not, (i) conflict with or violate any law,  order,
writ, injunction,  decree, statute, rule or regulation,  court order or judgment
applicable  to the Company or by which its property is bound or  affected,  (ii)
violate or conflict with the Restated Certificate of Incorporation or By-Laws of
the Company,  or (iii) result in a violation or breach of,  constitute a default
under (with or without due notice or lapse of time or both),  give to others any
rights of termination or cancellation of, or result in the creation of a Lien on
any of the  properties  or assets of the  Company  pursuant  to,  any  contract,
instrument,  permit,  license or franchise to which the Company is a party or by

the trusts  under such plans or the plan sponsor or the plan  administrator,  or
against  any  fiduciary  of the  Employee  Benefit  Plans  with  respect  to the
operation  of such plans  (other  than  routine  benefit  claims),  nor does the
Company  have  knowledge  of facts  which  could form a valid basis for any such
claim or lawsuit.

     (e) The  Employee  Benefit  Plans  have been  maintained,  in all  material
respects,  in accordance  with their terms and with all  provisions of ERISA and
the Code  (including  rules and  regulations  thereunder)  and other  applicable

of the Company nor any "party in interest" or "disqualified Person" with respect
to the Employee Benefit Plans has engaged in a "prohibited  transaction"  within
the meaning of Section  406 of ERISA or 4975 of the Code.  No  fiduciary  to any
Employee Benefit Plan has any current  liability for breach of fiduciary duty or
any other  failure to act or comply in  connection  with the  administration  or
investment of the assets of any Employee Benefit Plan.

<PAGE>


to those of the Company.  There is no material  claim  pending under any of such
policies or bonds as to which coverage has been  questioned,  denied or disputed
by the  underwriters  of such  policies or bonds.  All  premiums due and payable
under all such  policies and bonds have been paid by the Company and the Company
is  otherwise in  compliance  in all  material  respects  with the terms of such
policies and bonds.  The Company has no knowledge of any threatened  termination
of, or material premium increase with respect to, any of such policies.

opinion from  Wasserstein  Perella,  financial  advisor to the  Company,  to the

copy of which opinion has been delivered to the Purchaser.

disclose to the Purchaser any facts material to the Company's business,  results
of operations,  assets,  liabilities,  financial condition or prospects (in each
case excluding those relating to Omnitel).  No representation or warranty by the
Company in this  Agreement  and no  statement  by the  Company  in any  document
referred to herein (including the Schedules and Exhibits  hereto),  contains any
untrue  statement  of a  material  fact or  omits  to state  any  material  fact
necessary,  in order to make the statement  made herein or therein,  in light of
the circumstances under which they were made, not misleading.

it will  immediately  cease and cause to be terminated any existing  activities,
discussions or negotiations with any parties  conducted  heretofore with respect

necessary steps promptly to inform the Persons

                                       33

respect  to the  Company  or any  proposal  or offer  with  respect to any other

hereof or materially delay such consummation;

     SECTION 5.3. No Solicitation; Board Recommendation.

     (a) The Company  will not, and will use its best efforts to ensure that its
officers, directors, employees,  investment bankers, attorneys,  accountants and
other agents do not, directly or indirectly: (i) initiate, solicit or encourage,
or take any action to facilitate  (including by the  furnishing of  information)
the making of, any offer or proposal which  constitutes or is reasonably  likely
to lead to any Takeover Proposal,  (ii) enter into any agreement with respect to
any Takeover Proposal, or (iii) in the event of an unsolicited Takeover Proposal
for the Company  engage in  negotiations  or  discussions  with,  or provide any
information  or data  to,  any  Person  (other  than the  Purchaser,  any of its
affiliates  or  representatives  and  except  for  information  which  has  been

                                       36
<PAGE>


previously  publicly  disseminated  by the  Company)  relating  to any  Takeover
Proposal;  provided  however,  that nothing contained in this Section 5.3 or any
other provision hereof shall prohibit the Company or the Board of Directors from
(i) taking and disclosing to the Company's  stockholders a position with respect
to a tender or exchange offer by a third party pursuant to Rules 14d-9 and 14e-2
promulgated  under  the  Exchange  Act or (ii)  making  such  disclosure  to the
Company's  stockholders as, in the good faith judgment of the Board of Directors
after  receiving  advice from outside  counsel,  the Company deems  necessary to
comply with its fiduciary duties to the Company's  stockholders under applicable
law.

     (b)  Notwithstanding  the  foregoing,  prior to the  acceptance  of  Shares
pursuant  to the Offer,  the  Company may  furnish  information  concerning  its
business,   properties  or  assets  to  any  Person   pursuant  to   appropriate
confidentiality agreements, and may negotiate and participate in discussions and
negotiations with such Person concerning a Takeover Proposal  (provided that the
Company shall not agree to any exclusive right to negotiate with the Company) if
(x) such  entity  or group has on an  unsolicited  basis  submitted  a bona fide
written  proposal to the Company  relating to any such transaction that provides
for consideration  which the Board of Directors  determines in good faith, after
receiving advice from a nationally  recognized  investment banking firm, is more
favorable  to the  Company  and its  stockholders  than the Offer and the Merger
(taking  into account all relevant  factors) and which is not  conditioned  upon
obtaining  additional financing not fully committed at such time or, in the view
of a nationally  recognized  investment banking firm, is reasonably likely to be
obtained under then existing  market  conditions,  and (y) in the opinion of the
Board of  Directors,  after  receiving  advice from outside legal counsel to the
Company,  the failure to provide such information or access or to engage in such
discussions or negotiations  would likely cause the Board of Directors to breach
its  fiduciary  duties to the Company's  stockholders  under  applicable  law (a
Takeover  Proposal which satisfies  clauses (x) and (y) being referred to herein
as a "Superior  Proposal").  The Company shall promptly provide to the Purchaser
any  nonpublic  information  regarding  the Company  provided to any other party
which was not  previously  provided  to the  Purchaser.  If the  Company,  after
consultation with outside legal counsel, believes that a breach of its fiduciary
duties to the Company's  stockholders would likely occur, the Board of Directors
may  (subject  to  this  and  the  following  sentences)  inform  the  Company's
stockholders  that it no  longer  believes  that the  Offer  and the  Merger  is
advisable and no longer recommends approval (a "Subsequent Determination"),  but
only at a time that is after the fifth  business day following  the  Purchaser's
receipt of written notice advising the Purchaser that the Board of Directors has
received a Superior  Proposal  specifying  the material  terms and conditions of
such  Superior  Proposal  (and  including a copy thereof  with all  accompanying
documentation), identifying the Person making such Superior Proposal and stating

                                       37
<PAGE>


that it intends to make a  Subsequent  Determination.  Notwithstanding  anything
herein to the contrary,  prior to and  including  such fifth day the Company may
make such  public  disclosure  that is in its view  required  under the  Federal
securities laws, as evidenced by an opinion from outside counsel to the Company,
a copy of which shall be provided to Purchaser prior to such  disclosure.  After
providing such notice, the Company shall provide a reasonable opportunity to the
Purchaser to make such adjustments in the terms and conditions of this Agreement
and/or of the Option  Agreement  as would enable the Company to proceed with its
recommendation to its stockholders  without a Subsequent  Determination.  At any
time after five business  days  following  notification  to the Purchaser of the
Company's  intent to do so and if the Company has  otherwise  complied  with the
terms  of this  Section  5.3(b),  the  Board of  Directors  may  terminate  this
Agreement  pursuant to clause (ii) of Section 8.1(f) and enter into an agreement
with  respect  to  a  Superior  Proposal;   provided  that  the  Company  shall,
concurrently  with entering into such agreement,  pay or cause to be paid to the
Purchaser  the   Termination   Fee  (as  defined  in  Section  8.2(b)   hereof).
Notwithstanding any other provision of this Agreement,  the Company shall submit
this Agreement to its stockholders,  whether or not the Board of Directors makes
a Subsequent Determination.

     (c) Except as set forth in Section  5.3(b),  neither the Board of Directors
nor any committee  thereof shall (i) withdraw or modify,  or propose to withdraw
or modify, in a manner adverse to the Purchaser,  the approval or recommendation
by the Board of Directors or any such committee of the Offer,  this Agreement or
the Merger, (ii) approve or recommend,  or propose to approve or recommend,  any
Takeover Proposal or (iii) enter into any agreement with respect to any Takeover
Proposal.

                                   ARTICLE VI.

                              ADDITIONAL AGREEMENTS

     SECTION 6.1. Proxy Statement.  If required by the Exchange Act, as promptly
as practicable  after the  consummation of the Offer,  the Company shall prepare
and file with the SEC, and shall use all  reasonable  efforts to have cleared by
the  SEC,  and  promptly  thereafter  shall  mail  to  stockholders,  the  Proxy
Statement.  Except as set forth in Section  5.3(b),  the Proxy  Statement  shall
contain the recommendation of the Board of Directors in favor of the Merger.

     SECTION  6.2.  Meeting  of  Stockholders  of the  Company.  At the  Special

respects with all applicable laws and with all applicable  rules and regulations

and to  consummate  and make  effective  the Merger  and the other  transactions
contemplated  hereby.  Each of the parties  hereto agrees to use all  reasonable
efforts  to  obtain in a timely  manner  all  necessary  waivers,  consents  and
approvals and to effect all necessary  registrations and filings, and to use all
reasonable  efforts to take, or cause to be taken,  all other actions and to do,
or cause to be  done,  all  other  things  necessary,  proper  or  advisable  to

contemplated by this Agreement. In case at any time after the Effective Time any
further  action is  necessary  or  desirable  to carry out the  purposes of this
Agreement,  the proper  officers and  directors of the Company and the Purchaser
shall  use all  reasonable  efforts  to take,  or cause  to be  taken,  all such
necessary actions.

     SECTION 6.4. Notification of Certain Matters. The Company shall give prompt
notice to the  Purchaser  and the  Purchaser  shall  give  prompt  notice to the

warranty  contained in this Agreement to be untrue or inaccurate in any material
respect  at any time  from the date  hereof  to the  Effective  Time or (ii) any
condition set forth in Annex I hereto to be unsatisfied in any material  respect
at any time from the date  hereof  to the date the  Purchaser  purchases  Shares
pursuant  to the  Offer  and (b) any  material  failure  of the  Company  or the
Purchaser,  as the case may be,  or any  officer,  director,  employee  or agent
thereof,  to comply with or satisfy any  covenant,  condition or agreement to be
complied with or satisfied by it hereunder; provided, however, that the delivery
of any notice  pursuant to this Section 6.4 shall not limit or otherwise  affect
the remedies available hereunder to the party receiving such notice.

     SECTION 6.5. Access to Information.

     (a) From the date hereof to the  Effective  Time,  the Company  shall,  and
shall cause its officers,  directors,  employees, auditors and agents to, afford
the officers,  employees and agents of the  Purchaser  reasonable  access at all
reasonable times to its officers,  employees,  agents,  properties,  offices and
other  facilities and to all books and records,  and shall furnish the Purchaser

through its officers, employees or agents, may reasonably request.

     (b) Unless  otherwise  required by law and until the Appointment  Date, the
Purchaser agrees that it shall, and shall

                                       39

cause  its  affiliates  and  each  of  their  respective  officers,   directors,
employees,  financial advisors and agents (the "Purchaser Representatives"),  to
hold in strict  confidence  all data and  information  obtained by them from the
Company (unless such  information is or becomes publicly  available  without the
fault of any of the  Purchaser  Representatives  or  public  disclosure  of such
information  is required by law in the opinion of counsel to the  Purchaser) and
shall ensure that the Purchaser Representatives do not disclose such information
to others  without the prior  written  consent of the  Company.  Notwithstanding
anything  herein to the contrary,  the terms of the  Confidentiality  Agreement,
dated  December  1,  1998  (the  "Confidentiality  Agreement")  executed  by the
stockholders of Purchaser shall remain in full force and effect.

     (c) In the event of the termination of this Agreement, the Purchaser shall,
and shall cause its affiliates to, return  (without  maintaining any electronic,
digital,  magnetic or optical  representation  thereof)  promptly every document
furnished  to them by the Company or any of its  representatives  in  connection
with the transactions  contemplated  hereby and any copies (without  maintaining
any electronic,  digital,  magnetic or optical  representation  thereof) thereof
which may have been made, and shall cause the Purchaser  Representatives to whom
such documents  were furnished  promptly to return such documents and any copies
thereof any of them may have made,  other than  documents  filed with the SEC or
otherwise publicly available.

     SECTION 6.6.  Public  Announcements.  The  Purchaser  and the Company shall
consult with each other before issuing any press release or otherwise making any
public  statements  with  respect to the Offer or the Merger and shall not issue
any  such  press  release  or  make  any  such  public   statement  before  such
consultation, except as may be required by law.

     SECTION 6.7. Best Efforts;  Cooperation.  Upon the terms and subject to the
conditions hereof,  each of the parties hereto agrees to use its reasonable best
efforts to take or cause to be taken all  actions  and to do or cause to be done
all  things  necessary,  proper or  advisable  to  consummate  the  transactions
contemplated  by this  Agreement  and shall use its  reasonable  best efforts to
obtain  all  necessary  waivers,  consents  and  approvals,  and to  effect  all
necessary  filings  under the Exchange  Act and the HSR Act. The parties  hereto
shall  cooperate in responding to inquiries from, and making  presentations  to,
regulatory authorities.

     SECTION 6.8. Agreement to Defend and Indemnify.

     (a) It is  understood  and agreed  that the Company  shall,  to the fullest
extent permitted under Delaware Law and regardless of whether the Merger becomes
effective,  indemnify,  defend and hold harmless,  and after the Effective Time,
the Purchaser and the Surviving Corporation shall jointly and

                                       40
<PAGE>


severally, to the fullest extent permitted under Delaware Law, indemnify, defend
and hold  harmless the present and former  officers,  directors,  employees  and
agents of the  Company  ("Indemnified  Parties")  against  any costs or expenses
(including  reasonable  attorneys'  fees),  judgments,  fines,  losses,  claims,
damages,  liabilities  and amounts paid in  settlement  in  connection  with any
claim, action, suit,  proceeding or investigation,  including without limitation
liabilities  arising  out  of  this  transaction,  under  the  Exchange  Act  in
connection  with the Offer or the  Merger,  and in the event of any such  claim,
action, suit,  proceeding or investigation  (whether arising before or after the
Effective  Time),  (i) the Company or the  Surviving  Corporation  shall pay the
reasonable  fees and expenses of counsel  selected by the  Indemnified  Parties,
which counsel shall be reasonably  satisfactory  to the Company or the Surviving
Corporation,  promptly as statements therefor are received, and (ii) the Company
and the Surviving  Corporation will cooperate in the defense of any such matter;
provided,  however, that neither the Company nor the Surviving Corporation shall
be liable for any settlement  effected  without its prior written consent (which
consent shall not be unreasonably withheld); and further, provided, that neither
the  Company nor the  Surviving  Corporation  shall be obliged  pursuant to this
Section 6.8 to pay the fees and  disbursements  of more than one counsel for all
Indemnified  Parties in any single  action  except to the  extent  that,  in the
opinion of counsel for the Indemnified  Parties, two or more of such Indemnified
Parties have  conflicting  interests  in the outcome of such  action.  For three
years after the Effective Time, the Surviving  Corporation  shall be required to
maintain or obtain  officers' and directors'  liability  insurance  covering the
Indemnified  Parties who are  currently  covered by the  Company's  officers and
directors  liability  insurance  policy  with  respect  to matters  existing  or
occurring at or prior to the  Effective  Time on terms not less  favorable  than
those in effect on the date hereof in terms of coverage and  amounts;  provided,
however,  that if the aggregate  annual  premiums for such insurance at any time
during such period shall exceed 150% of the per annum rate of premium  currently
paid by the  Company for such  insurance  on the date of this  Agreement,  which
amount  is  disclosed  on  Schedule  6.8 of the  Disclosure  Schedule,  then the
Purchaser  shall cause the Company (or the  Surviving  Corporation  if after the
Effective  Time) to, and the Company (or the Surviving  Corporation if after the
Effective Time) shall, provide the maximum coverage that shall then be available
at an annual premium equal to 150% of such rate.  This Section 6.8 shall survive
the  consummation  of the  Merger.  The  Purchaser  shall  cause  the  Surviving
Corporation to reimburse all expenses,  including reasonable attorney's fees and
expenses, incurred by any Person to enforce the obligations of the Purchaser and
the Surviving  Corporation under this Section 6.8.  Notwithstanding  Section 9.7
hereof, this Section 6.8 is intended to be for the benefit of and to grant third
party rights to Indemnified  Parties  whether or not parties to this  Agreement,

                                       41
<PAGE>


and each of the  Indemnified  Parties shall be entitled to enforce the covenants
contained herein.

     (b) If the Surviving  Corporation  or any of its  successors or assigns (i)
consolidates  with  or  merges  into  any  other  Person  and  shall  not be the
continuing or surviving corporation or entity of such consolidation or merger or
(ii)  transfers all or  substantially  all of its  properties  and assets to any
Person,  then and in each such case,  proper provision shall be made so that the
successors and assigns of the Surviving  Corporation  assume the obligations set
forth in this Section 6.8.

     SECTION 6.9. Debt Offer.

     (a) The  Company  shall,  within 10 days of  receiving  any  request by the
Purchaser  to do so,  commence  an offer to purchase  (accompanied  by a related
solicitation  of consents  regarding  covenant  amendments) all of the Company's
outstanding 9 1/2% Senior  Discount Notes due 2005 (the "Senior  Notes") on such
customary terms and conditions as are acceptable to the Purchaser and reasonably
satisfactory  to the Board of Directors  (the "Debt  Offer").  The Company shall
waive any of the  conditions to the Debt Offer and make any other changes in the
terms and  conditions of the Debt Offer as may be requested by the Purchaser and
as are reasonably satisfactory to the Board of Directors,  and the Company shall
not, without the Purchaser's prior written consent, waive any material condition
to the Debt  Offer,  make any  changes to the terms and  conditions  of the Debt
Offer set forth in Schedule 6.9 hereto or make any other material changes in the
terms and conditions of the Debt Offer.  The Company  covenants and agrees that,
subject to the terms and conditions of this Agreement, including but not limited
to the conditions in the Debt Offer,  it will accept for payment and pay for the
Senior Notes as soon as reasonably practicable after such conditions to the Debt
Offer are satisfied and it is permitted to do so under applicable law,  provided
that the Company shall use  reasonable  best efforts to coordinate the timing of
any  such   purchase  with  the  Purchaser  in  order  to  obtain  the  greatest
participation in the Debt Offer.

     (b)  Promptly  following  the date of this  Agreement,  the Company and the
Purchaser  shall  prepare an offer to purchase for the Senior Notes and forms of
the related  letters of transmittal  and summary  advertisement,  as well as all
other  information  and  exhibits  (collectively,  the  "Debt  Documents").  All
mailings of the Debt  Documents to the holders of the Senior Notes in connection
with the Debt Offer shall be subject to the prior  review,  comment and approval
of the Purchaser (which approval shall not be unreasonably withheld or delayed).
The Company will use its reasonable  best efforts to cause the Debt Documents to
be  mailed  to the  holders  of the  Senior  Notes as  promptly  as  practicable
following receipt of the request from the Purchaser under paragraph (a) above to
do so. The  Company  agrees  promptly

                                       42
<PAGE>


to correct any  information  in the Debt  Documents that shall be or have become
false or misleading in any material respect.

     (c) The  Purchaser  shall  provide to the  Company all funds  necessary  to
consummate  the Debt  Offer on terms  reasonably  satisfactory  to the  Board of
Directors.  No term or condition of such funding  shall  prevent or restrict the
consummation of the Merger.

     (d) In the event that the Debt Offer is commenced but is terminated without
consummation,  and such failure to consummate is not the result of the Company's
breach,  the Purchaser  will  reimburse the Company for any and all expenses and
fees incurred by the Company in connection with the Debt Offer.

     SECTION  6.10.  Qualified  Electing  Fund  Documentation.  The  Company has
prepared,  or  caused  to be  prepared,  and has  submitted  for  review  to the
Purchaser on or prior to the date hereof, Internal Revenue Service Form 8621 and
such amended United States Federal income Tax Returns (and other documentation),
as required  for the Company to make a  retroactive  "Qualified  Electing  Fund"
election,  pursuant to Treasury Regulations Section 1.1295-3T(f),  effective for
the Company's entire holding period,  with respect to the Company's  interest in
Omnitel.  Such  documentation  shall be  prepared  in such manner as would fully
satisfy the requirements of Treasury  Regulations  Section  1.1295-3T(g) and the
private  letter  ruling  received by the Company dated  November 18, 1998.  Such
documentation  shall not be filed with the Internal  Revenue Service without the
Purchaser's  prior written  consent,  which  consent  shall not be  unreasonably
withheld or delayed.  The Purchaser will take all actions necessary to file such
Forms 862i and such amended Tax Returns, and shall cooperate with the Company in
connection therewith.

     SECTION 6.11.  Omnitel  Agreement.  Notwithstanding  anything herein to the
contrary,  (i) it shall not  constitute a failure of any condition to the Merger
set forth in Article VII of this Agreement nor to the Offer set forth in Annex I
of this Agreement,  which  conditions are for the benefit of the Purchaser,  if,
and (ii) the Purchaser agrees that it will not terminate or seek to terminate or
otherwise impair its performance of this Agreement in any manner as a result of,
in  either  case,  any  claim,  action,  suit,  proceeding  (including,  without
limitation,  arbitration  proceeding) or other  alternative  dispute  resolution
proceeding or investigation is commenced or threatened against the Company,  the
Purchaser,  Mannesmann,  Olivetti  or Oliman  Holding  B.V.  arising  out of, or
relating to, the Joint Venture Agreement, dated as of May 3, 1990, among Ing. C.
Olivetti & C., S.p.A., Bell Atlantic International, Inc., CCI Partnership, Inc.,
Shearson Lehman Hutton Eurocell Italy,  Inc. and Swedish Telecomm  International
AB, as amended  November 24, 1993 and February 23, 1994, and in connection  with
the  execution  and  delivery  of this  Agreement  and the  consummation  of the
transactions  contemplated

     The  respective  obligations  of each party to effect  the Merger  shall be
subject to the following conditions,  provided that the obligation of each party
shall not be relieved by the failure of any such  conditions  if such failure of
any such  conditions is the proximate  result of any breach by such party of any
of its material obligations under this Agreement.

     SECTION 7.1.  Offer.  The Purchaser  shall have made, or caused to be made,
the Offer and shall  have  purchased,  or  caused to be  purchased,  the  Shares
pursuant to the Offer; provided, however, that this condition shall be deemed to
have been  satisfied  with respect to the  obligation of the Purchaser to effect
the  Merger if the  Purchaser  fails to accept  for  payment  or pay for  Shares
pursuant  to the  Offer  in  violation  of the  terms  of the  Offer  or of this
Agreement.

     SECTION 7.2. Stockholder Approval. The Merger and this Agreement shall have
been  approved  and adopted by the  requisite  vote of the  stockholders  of the
Company, if required by Delaware Law.

     SECTION 7.3. No Challenge.  No statute, rule, regulation,  judgment,  writ,
decree,  order or injunction shall have been  promulgated,  enacted,  entered or
enforced,  and no other  action  shall have been  taken,  by any  government  or
governmental,  administrative  or  regulatory  authority  or  by  any  court  of
competent  jurisdiction,  that in any of the  foregoing  cases has the effect of
making illegal or directly or indirectly restraining, prohibiting or restricting
the consummation of the Merger.

                                  ARTICLE VIII.

                        TERMINATION, AMENDMENT AND WAIVER

<PAGE>


by the Purchaser as a result of the occurrence of any of the events set forth in
Annex I; or

     (c) By  either  the  Purchaser  or the  Company  if a  court  of  competent
jurisdiction or governmental,  regulatory or administrative agency or commission
shall have issued an order,  decree or ruling or taken any other  action  (which

lift), in each case permanently restraining,  enjoining or otherwise prohibiting
the transactions contemplated by this Agreement; or

obligations  under this Agreement,  the purchase of Shares pursuant to the Offer

with  Section  5.3(b)  with  respect to a Superior  Proposal  which the Board of
Directors has  determined is more favorable to the  stockholders  of the Company
than the transactions  contemplated  hereby;  provided that it has complied with
all provisions  thereof,  including the notice  provision  therein,  and that it
makes simultaneous  payment of the Termination Fee, plus any amounts then due as
a reimbursement of expenses; or

     (g) By the  Purchaser  if, prior to the purchase of Shares  pursuant to the
Offer the Company shall have breached any  representation,  warranty or covenant
or other agreement contained in this Agreement, which breach (i) would give rise

hereto and (ii)  cannot be or has not been cured  within ten days of the receipt
of written notice thereof; or

     (h) By the  Purchaser,  at any time  prior to the  purchase  of the  Shares

not have rejected such proposal  within twenty (20) business days of its receipt
or, if sooner, the date its existence first becomes publicly  disclosed,  or (v)
any Person or group (as defined in Section  13(d)(3) of the Exchange  Act) other
than the Purchaser or any of its  Subsidiaries  or affiliates  shall have become
the beneficial  owner of more than 15% of the  outstanding  Company Common Stock
(either on a primary or a fully diluted  basis);  provided,  however,  that this
provision  shall  not  apply  to any  Person  that  owns  more  than  15% of the
outstanding Shares on the date hereof; or

     a  declaration  of a banking  moratorium  or any  suspension of payments in
     respect of banks in the United States (whether or not  mandatory),  (iii) a

part at any time and from time to time,  in each case,  in the  exercise  of the
good faith judgment of the Purchaser and subject to the terms of this Agreement.
The failure by the Purchaser at any time to exercise any of the foregoing rights
shall  not be deemed a waiver of any such  right  and each such  right  shall be
deemed an ongoing right which may be asserted at any time and from time to time.







                                OPTION AGREEMENT


     STOCK OPTION AGREEMENT,  dated as of December 11, 1998 (this  "Agreement"),
between Kensington Acquisition Sub, Inc., a Delaware corporation  ("Purchaser"),
and Cellular  Communications  International,  Inc., a Delaware  corporation (the
"Company").

     WHEREAS,  Purchaser  and the Company,  concurrently  with the execution and
delivery of this  Agreement,  have entered into an Agreement and Plan of Merger,
dated as of the date hereof (the "Merger Agreement"), providing for, among other
things, the merger of Purchaser with and into the Company (the "Merger"); and

     WHEREAS,  as a condition to the  willingness of Purchaser to enter into the
Merger Agreement, Purchaser has required that the Company agree, and in order to
induce Purchaser to enter into the Merger  Agreement the Company has agreed,  to
grant  Purchaser the Option (as defined below) upon the terms and subject to the
conditions of this Agreement.

     NOW THEREFORE,  in  consideration of the foregoing and the mutual promises,
representations,  warranties,  covenants and agreements  contained herein and in
the Merger Agreement,  the parties hereto, intending to be legally bound hereby,
agree as follows:

                                    ARTICLE I
                                   THE OPTION

     SECTION 1.1 Grant of Option.  The Company  hereby  grants to  Purchaser  an
irrevocable  option (the  "Option")  to purchase  up to  4,338,133  newly-issued
shares ("Shares") of the Common Stock, par value $.01 per share ("Company Common
Stock"),  of the Company at a purchase  price per share of $65.75 (the "Exercise
Price"),  in the manner  set forth in  Sections  1.2 and 1.3 of this  Agreement;
provided,  however,  that in no event  shall the  number of Shares for which the
Option is  exercisable  exceed  19.9% of the  Company's  issued and  outstanding
shares of Company  Common Stock.  The number of Shares that may be received upon
the exercise of the Option and the Exercise  Price are subject to  adjustment as
herein set forth. This Agreement shall terminate,  and the Option hereby granted
shall  expire,  on the  earliest  of (i) the  Effective  Time (as defined in the
Merger  Agreement)  and (ii) to the extent  that no Option  Notice  (as  defined
below)  has  theretofore  been  given by  Purchaser,  six (6)  months  after any
termination of the Merger Agreement  pursuant to Section 8.1(b),  (f)(ii),  (g),
(h) or (i)  thereof  and at the  time of  termination

<PAGE>


of the Merger Agreement pursuant to Section 8.1(a), (c), (d), (e) or (f)(i).

     SECTION 1.2  Exercise Of Option.  At any time or from time to time prior to
the termination of the Option granted  hereunder in accordance with the terms of
this Agreement  (other than such time as Purchaser is in material  breach of its
obligations  under  the  Merger  Agreement),  Purchaser  (or its  designee)  may
exercise the Option, in whole or in part, if on or after the date hereof:

     (a)  any  corporation,   partnership,   individual,  trust,  unincorporated
association,  or other entity or "person" (as defined in Section 13(d)(3) of the
Securities  Exchange Act of 1934, as amended (the  "Exchange  Act"),) other than
Purchaser or any of its  "affiliates" (as defined in the Exchange Act) (a "Third
Party"), shall have:

          (i)  commenced or announced an intention to commence a tender offer or
     exchange offer for any shares of Company Common Stock,  the consummation of
     which would result in "beneficial ownership" (as defined under the Exchange
     Act) by such Third Party  (together with all such Third Party's  affiliates
     and  "associates"  (as such term is defined in the Exchange Act)) of 15% or
     more of the then  outstanding  voting  equity of the  Company  (either on a
     primary or a fully diluted basis); or

          (ii) acquired  beneficial  ownership of shares of Company Common Stock
     which,  when  aggregated  with any shares of Company  Common Stock  already
     owned by such Third Party,  its affiliates and associates,  would result in
     the aggregate  beneficial ownership by such Third Party, its affiliates and
     associates  of 15% or more of the then  outstanding  voting  equity  of the
     Company (either on a primary or a fully diluted basis); provided,  however,
     that "Third  Party" for  purposes of this clause (ii) shall not include any
     corporation,  partnership, person, other entity or group which beneficially
     owns more than 15% of the outstanding  voting equity of the Company (either
     on a primary or a fully diluted  basis) as of the date hereof and that does
     not, after the date hereof, increase such ownership percentage by more than
     an additional 1% of the outstanding voting equity of the Company (either on
     a primary or a fully diluted basis); or

     (b) any of the events described in Section 8.1(g) (so long as following the
date  hereof  but prior to any  termination  there  shall  have been a  Takeover
Proposal Interest (as defined in the Merger Agreement)), 8.1(h) or 8.1(i) of the
Merger  Agreement that would allow  Purchaser to terminate the Merger  Agreement
has occurred  (but without the  necessity of  Purchaser  having  terminated  the
Merger Agreement).

                                       2
<PAGE>


     In the  event  that  Purchaser  wishes to  exercise  all or any part of the
Option,  Purchaser shall give written notice (the "Option Notice," with the date
of the Option Notice being hereinafter  called the "Notice Date") to the Company
specifying  the  number  of Shares  it will  purchase  and a place and date (not
earlier than three (3) nor later than twenty (20)  business days from the Notice
Date) for  closing  such  purchase  (a  "Closing").  Purchaser's  obligation  to
purchase  Shares upon any exercise of the Option is subject (at its election) to
the conditions  that (i) no  preliminary or permanent  injunction or other order
against the purchase,  issuance or delivery of the Shares issued by any federal,
state or foreign  court of  competent  jurisdiction  shall be in effect  (and no
action or proceeding  shall have been  commenced or  threatened  for purposes of
obtaining such an injunction or order), (ii) any applicable waiting period under
the Hart-Scott-Rodino  Antitrust  Improvements Act of 1976, as amended (the "HSR
Act") shall have  expired and (iii) there shall have been no material  breach of
the  representations,   warranties,  covenants  or  agreements  of  the  Company
contained in this Agreement or the Merger Agreement; provided, however, that any
failure by  Purchaser  to  purchase  Shares  upon  exercise of the Option at any
Closing as a result of the  nonsatisfaction  of any of such conditions shall not
affect  or  prejudice  Purchaser's  right  to  purchase  such  Shares  upon  the
subsequent  satisfaction  of such  conditions.  Upon request by  Purchaser,  the
Company will promptly take all action  required to effect all necessary  filings
by the Company under the HSR Act.

     SECTION  1.3  Purchase of Shares.  At any  Closing,  (i) the  Company  will
deliver to Purchaser the certificate or certificates  representing the number of
Shares being  purchased in proper form for transfer  upon exercise of the Option
in the denominations  designated by Purchaser in the Option Notice,  and, if the
Option  has been  exercised  in part,  a new  Option  evidencing  the  rights of
Purchaser  to  purchase  the  balance of the Shares  subject  thereto,  and (ii)
Purchaser shall pay the aggregate  purchase price for the Shares to be purchased
by delivery to the Company of a certified or bank cashier's check payable in New
York  Clearing  House  funds to the order of the  Company  in the  amount of the
Exercise Price times the number of Shares to be purchased.

     SECTION 1.4 Adjustments  Upon Share Issuances,  Changes in  Capitalization,
etc. (a) In the event of any change in Company  Common Stock or in the number of
outstanding  shares of  Company  Common  Stock by  reason  of a stock  dividend,
split-up,   recapitalization,   combination,   exchange  of  shares  or  similar
transaction  or any other change in the  corporate  or capital  structure of the
Company  (including,  without  limitation,  the  declaration  or  payment  of an
extraordinary  dividend of cash,  securities  or other  property),  the type and
number of the Shares to be issued by the  Company  upon  exercise  of the Option
shall be  adjusted  appropriately,  and  proper  provision  shall be made in the

                                       3
<PAGE>


agreements  governing such  transaction,  so that  Purchaser  shall receive upon
exercise  of the Option the  number and class of shares or other  securities  or
property that  Purchaser  would have  received in respect to the Company  Common
Stock if the Option had been exercised  immediately  prior to such event, or the
record date therefor, as applicable, and the holder of such Company Common Stock
had  elected to the fullest  extent it would have been  permitted  to elect,  to
receive such securities, cash or other property.

     (b) In the event that the  Company  shall  enter into an  agreement  (i) to
consolidate  with or merge into any person,  other than  Purchaser or one of its
subsidiaries,  and shall not be the continuing or surviving  corporation of such
consolidation or merger, (ii) to permit any person,  other than Purchaser or one
of its  subsidiaries,  to merge into the Company  and the  Company  shall be the
continuing or surviving  corporation,  but, in connection with such merger,  the
then  outstanding  shares of  Company  Common  Stock  shall be  changed  into or
exchanged  for stock or other  securities  of the Company or any other person or
cash or any other property,  or then outstanding  shares of Company Common Stock
shall after such merger  represent less than 50% of the  outstanding  shares and
share  equivalents  of the surviving  corporation  or (iii) to sell or otherwise
transfer  all or  substantially  all of its  assets to any  person,  other  than
Purchaser  or one of its  subsidiaries,  then,  and in each  such  case,  proper
provision  shall be made in the agreements  governing  such  transaction so that
Purchaser  shall  receive  upon  exercise  of the Option the number and class of
shares or other  securities  or property that  Purchaser  would have received in
respect of Company  Common  Stock if the Option had been  exercised  immediately
prior to such transaction,  or the record date therefor, as applicable,  and the
holder of such Company  Common Stock had elected to the fullest  extent it would
have  been  permitted  to  elect,  to  receive  such  securities,  cash or other
property.

     (c) The rights of Purchaser under this Section 1.4 shall be in addition to,
and shall in no way limit,  its rights against the Company for any breach of the
Merger Agreement.

     (d)  The  provisions  of  this  Agreement  shall  apply  with   appropriate
adjustments to any securities for which the Option becomes exercisable  pursuant
to this Section 1.4.

                                   ARTICLE III

                   REPRESENTATIONS AND WARRANTIES OF PURCHASER

     Purchaser hereby represents and warrants to the Company as follows:

     SECTION  3.1  Authority   Relative  to  this  Agreement.   Purchaser  is  a
corporation  duly organized and validly  existing under the laws of the State of
Delaware.  Purchaser  has all  necessary  power  and  authority  (corporate  and
otherwise)  to execute and deliver this  Agreement,  to perform its  obligations
hereunder and to consummate the transactions  contemplated hereby. The execution
and  delivery  of  this  Agreement  and the  consummation  by  Purchaser  of the
transactions  contemplated  hereby  have  been duly  authorized  by the Board of
Directors  of  Purchaser,  and no  other  corporate  proceeding  on the  part of
Purchaser  is  necessary  to  authorize  this  Agreement  or  for  Purchaser  to
consummate  such  transactions.  This  Agreement  has  been  duly  executed  and
delivered  by  Purchaser  and,  assuming its due  authorization,  execution  and
delivery by the Company,  constitutes a legal,  valid and binding  obligation of
Purchaser, enforceable against Purchaser in accordance with its terms.

     SECTION 3.2 No Conflict,  Required  Filing and Consents.  The execution and
delivery of this  Agreement by Purchaser  do not,  and the  performance  of this
Agreement by Purchaser will not, (i) conflict with or violate the organizational
documents of Purchaser, (ii) conflict with or violate any law, rule, regulation,
order, judgment or decree applicable to Purchaser or by which Purchaser is bound
or affected,  (iii) result in any breach of or constitute a default (or an event
that with notice or lapse of time or both would become a default) under, or give
to others any rights of termination, amendment, acceleration or cancellation of,
any agreement,  contract,  indenture, note or instrument to which Purchaser is a
party  or by  which  it is  bound or  affected  or (iv)  except  for  applicable
requirements,  if any, of the HSR Act, the Exchange Act and the Securities  Act,
require any filing by Purchaser with, or any permit,  authorization,  consent or
approval of, any  governmental  or  regulatory  authority,  domestic or foreign,
except in the case of each of the  foregoing  clauses (i)  through  (iv) for any
such conflicts,  violations,  breaches, defaults, failures to file or obtain the
consent or approval  of, or other  occurrences  that would not cause or create a
material  risk of  non-performance  or delayed  performance  by Purchaser of its
obligations under this Agreement. 

     SECTION 3.3  Investment  Intent.  The  purchase of Shares  pursuant to this
Agreement is for the account of Purchaser for the purpose of investment  and not
with a view to or for sale in connection  with any  distribution  thereof within
the  meaning of

                                       6
<PAGE>


the Securities Act and the rules and regulations promulgated thereunder.


                                   ARTICLE IV

                              ADDITIONAL AGREEMENTS

     SECTION 4.1 Registration  Rights;  Listing of Shares.  (a) Upon the written
request of Purchaser, the Company agrees to effect up to two registrations under
the Securities Act and any applicable state securities laws covering any part or
all of the Option  (provided that only Shares will be distributed to the public)
and  any  part  or all of the  Shares  purchased  under  this  Agreement,  which
registration  shall be continued in effect for 90 days,  unless,  in the written
opinion  of  counsel to the  Company,  addressed  to  Purchaser  and  reasonably
satisfactory in form and substance to counsel for Purchaser,  such  registration
is not  required  for the sale and  distribution  of such  Shares in the  manner
contemplated by Purchaser.  The registration effected under this paragraph shall
be effected at the Company's expense except for any underwriting commissions. If
Shares are offered in a firm commitment  underwriting,  the Company will provide
reasonable and customary  indemnification  to the underwriters.  In the event of
any demand for  registration  pursuant to this paragraph,  the Company may delay
the filing of the  registration  statement  for a period of up to 90 days if, in
the good faith judgment of the Board of Directors of the Company,  such delay is
necessary in order to avoid  interference  with a planned  material  transaction
involving  the  Company.  In the event the  Company  effects a  registration  of
Company  Common  Stock for its own account or for any other  stockholder  of the
Company  (other than on Form S-4 or Form S-8 or any successor or similar  form),
it shall allow Purchaser to participate in such registration; provided, however,
that if the managing underwriters in such offering advise the Company in writing
that in their opinion the number of shares of Company Common Stock  requested to
be included in such  registration  exceeds the number  which can be sold in such
offering,  the Company  will  include the  securities  requested  to be included
therein pro rata among the holders requesting to be included.

     (b) The Company  shall,  at its expense,  use its best efforts to cause the
Shares to be  approved  for  listing on the Nasdaq  National  Market (the "NNM")
subject to notice of issuance,  as promptly as practicable following the date of
this  Agreement,  and will provide  prompt  notice to the NNM of the issuance of
each Share pursuant to any exercise of the Option.

     SECTION 4.2 Right to Sell Option. At any time that Purchaser is entitled to
exercise the Option pursuant to Section 1.2 hereof,  Purchaser may elect, in its
sole  discretion,  to sell the Option to the Company in lieu of  exercising  the
Option.  The

                                       7
<PAGE>


Company  shall be required to purchase  the Option from  Purchaser  on the third
business  day  after the  Purchaser  gives the  Company  written  notice of such
election for a cash price  (payable by certified or official  bank check in same
day funds to  Purchaser or its  designee)  equal to the product of the number of
Shares then  covered by the Option  multiplied  by the excess over the  Exercise
Price of the greater of (x) the closing price of a share of Company Common Stock
on the NNM on the last  trading day prior to the date of such notice and (y) the
highest  price per share of Company  Common Stock paid or proposed to be paid to
any holder  thereof by any person in any  Takeover  Proposal  (as defined in the
Merger Agreement). The Company shall give Purchaser prompt written notice of the
occurrence of any event set forth in Section 1.2 hereof and of any agreements or
proposals  relating  to such an event,  but the  failure to give any such notice
shall not limit  Purchaser's right to require the Company to purchase the Option
pursuant to this Section 4.2.

     SECTION 4.3 Limitation on Profit. (a)  Notwithstanding  any other provision
of this Agreement, in no event shall Purchaser's Total Profit (as defined below)
exceed $14 million and, if it otherwise would exceed such amount,  Purchaser, at
its sole  election,  shall  either  (a) reduce  the  number of shares of Company
Common Stock subject to the Option,  (b) deliver to the Company for cancellation
Shares  previously  purchased by  Purchaser,  (c) pay  cash to the  Company,  or
(d) any combination  thereof, so that Purchaser's actually realized Total Profit
shall not exceed $14 million after taking into account the foregoing actions.

     (b) As used herein, the term "Total Profit" shall mean the aggregate amount
(before  taxes) of the  following:  (i) (x) the  net cash  amounts  received  by
Purchaser  pursuant  to the sale of Shares (or any other  securities  into which
such Shares are  converted or  exchanged) to any  unaffiliated  party,  less (y)
Purchaser's  purchase price of such Shares,  and (ii) any  Notional Total Profit
(as defined below).

     (c) As used herein,  the term  "Notional  Total Profit" with respect to the
total  number of Shares as to which  Purchaser  could  propose to  exercise  the
Option  shall be the Total  Profit  determined  as of the date of such  proposal
assuming  that the Option were fully  exercised  on such date for such number of
Shares and  assuming  that such Shares,  together  with all other Shares held by
Purchaser and its affiliates as of such date,  were sold for cash at the closing
market  price for the  Company  Common  Stock as of the close of business on the
preceding trading day (less customary brokerage commissions).

     SECTION 4.4 Transfer of Shares; Restrictive Legend. Purchaser agrees not to
transfer or otherwise dispose of the Shares,  or any interest  therein,  without
first  providing to the Company an opinion of counsel for Purchaser,  reasonably

                                       8
<PAGE>


satisfactory  in form and  substance to counsel for the  Company,  to the effect
that such transfer or  disposition  will not violate the  Securities  Act or any
applicable  state law governing the offer and sale of securities,  and the rules
and  regulations  thereunder.  Purchaser  further agrees to the placement on the
certificate(s) representing the Shares of the following legend:

          "THE  SECURITIES   REPRESENTED  BY  THIS  CERTIFICATE  HAVE  NOT  BEEN
     REGISTERED  UNDER  THE  SECURITIES  ACT OF  1933,  AS  AMENDED,  AND MAY BE
     REOFFERED  OR SOLD  ONLY IF SO  REGISTERED  OR IF AN  EXEMPTION  FROM  SUCH
     REGISTRATION IS AVAILABLE."

provided  that upon  provision  to the  Company of any  opinion  of counsel  for
Purchaser,  reasonably  satisfactory  in form and  substance  to counsel for the
Company,  to the  effect  that  such  legend  is no  longer  required  under the
provisions  of the  Securities  Act or applicable  state  securities  laws,  the
Company shall  promptly  cause new  unlegended  certificates  representing  such
Shares  to  be  issued  to  Purchaser   against   surrender  of  such   legended
certificates.

     SECTION  4.5 Best  Efforts.  Subject  to the terms and  conditions  of this
Agreement, Purchaser and the Company shall each use its best efforts to take, or
cause to be  taken,  all  actions,  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.
Each party shall  promptly  consult  with the other and  provide  any  necessary
information and material with respect to all filings made by such party with any
governmental  or regulatory  authority in connection  with this Agreement or the
transactions contemplated hereby.

     SECTION 4.6 Further Assurances. The Company shall perform such further acts
and execute such further documents and instruments as may reasonably be required
to vest in Purchaser the power to carry out the provisions of this Agreement. If
Purchaser shall exercise the Option, or any portion thereof,  in accordance with
the  terms  of  this   Agreement,   the  Company   shall,   without   additional
consideration,  execute and deliver all such further  documents and  instruments
and take all such further  action as Purchaser  may  reasonably  request for the
purpose  of  effectively  carrying  out the  transactions  contemplated  by this
Agreement.

     SECTION 4.7 Survival. All of the representations,  warranties and covenants
contained  herein shall  survive a Closing and shall be deemed to have been made
as of the date hereof and as of the date of each Closing.

the other party  hereto,  except that the rights and  obligations  of  Purchaser
hereunder may, upon written notice to the Company prior to or promptly following
such action, be assigned by Purchaser to any of its corporate affiliates, but no
such  transfer  shall  relieve  Purchaser of its  obligations  hereunder if such
transferee does not perform such obligations.

     SECTION 5.4 Severability.  The provisions of this Agreement shall be deemed
severable and the invalidity or  unenforceability  of any  provisions  hereof or
thereof shall not affect the validity and enforceability of the other provisions
hereof. If any provision of this Agreement,  or the application  thereof, to any
person  or  entity or any  circumstances  is  invalid  or  unenforceable,  (i) a
suitable and equitable provision shall be substituted therefor in order to carry
out,  so far as may be valid and  enforceable,  the intent  and  purpose of such
invalid and unenforceable provision and (ii) the remainder of this Agreement and
the  application of such provision to other persons,  entities or  circumstances

                             STOCKHOLDERS AGREEMENT


     STOCKHOLDERS  AGREEMENT (this "Agreement"),  dated as of December 11, 1998,
by and among Cellular Communications International, Inc., a Delaware corporation
(the  "Company"),  Kensington  Acquisition  Sub,  Inc.,  a Delaware  corporation
("Purchaser"), and the persons listed on Schedule 1 hereto (the "Stockholders").

                              W I T N E S S E T H:

     WHEREAS,  concurrently  with the execution and delivery of this  Agreement,
the Company and  Purchaser  have entered  into an Agreement  and Plan of Merger,
dated as of the date hereof (as such  agreement  may  hereafter  be amended from
time to time, the "Merger  Agreement"),  pursuant to which,  among other things,
Purchaser will make a tender offer (the "Offer") for all  outstanding  shares of
common stock, par value $.01 per share ("Shares"),  of the Company at a price of
$65.75 per Share (the "Offer Price"),  net to the seller in cash, to be followed
by a  merger  of  Purchaser  with  and into the  Company,  and each  issued  and
outstanding  Share,  except  as set  forth  in the  Merger  Agreement,  will  be
converted into the right to receive the Offer Price;

     WHEREAS,  the Stockholders are the Beneficial Owners (as defined below) and
owners of record,  and have the sole  right to vote and  dispose  of,  Shares as
indicated on Schedule 1 hereto (with respect to such Stockholder,  together with
any other Shares acquired by such  Stockholder  after the date hereof and during
the term of the Agreement, collectively the "Owned Shares"); and

     WHEREAS,  as an inducement  and a condition to its entering into the Merger
Agreement  and  incurring  the  obligations  set forth  therein,  Purchaser  has
required that the Stockholders enter into this Agreement.

     NOW, THEREFORE,  in consideration of the foregoing and the mutual promises,
representations,  warranties,  covenants and agreements  contained herein and in
the Merger Agreement,  the parties hereto, intending to be legally bound hereby,
agree as follows:
<PAGE>


     1.  Certain  Definitions.  Capitalized  terms not  defined  herein have the
respective meanings ascribed to them in the Merger Agreement.  In addition,  for
purposes of this Agreement:

     "Affiliate"  means, with respect to any specified  Person,  any Person that
directly,  or indirectly  through one or more  intermediaries,  controls,  or is
controlled by, or is under common control with, the Person specified.

     "Beneficially  Own",  "Beneficial  Owner" or  "Beneficial  Ownership"  with
respect to any securities means having "beneficial ownership" of such securities
(as  determined  pursuant  to Rule  13d-3  under the  Exchange  Act),  including
pursuant  to any  agreement,  arrangement  or  understanding,  whether or not in
writing. Without duplicative counting of the same securities by the same holder,
securities  Beneficially Owned by a Person shall include securities Beneficially
Owned by all  Affiliates  of such  Person and all other  Persons  with whom such
Person  would  constitute a "group"  within the meaning of Section  13(d) of the
Exchange Act and the rules promulgated thereunder.

     "Person" means an individual,  corporation,  partnership, limited liability
company, joint venture, association, trust, unincorporated organization or other
entity.

     "Representative"  means,  with respect to any Person,  as applicable,  such
Person's officers,  directors,  employees, agents and representatives (including
any  investment  banker,  financial  advisor,  agent,  representative  or expert
retained by or acting on behalf of such Person or its Subsidiaries).

     "Transfer" means, with respect to a security,  the sale, transfer,  pledge,
hypothecation,  encumbrance,  assignment or  disposition of such security or the
Beneficial  Ownership thereof,  the offer to make such a sale, transfer or other
disposition, and each option, agreement,  arrangement or understanding,  whether
or not in writing, to effect any of the foregoing.  As a verb,  "Transfer" shall
have a correlative meaning.

     2. Agreement to Tender;  Voting of Owned Shares; Proxy. (a) If requested by
the  Purchaser,  the Company  shall take all actions  necessary to provide that,
prior to the Expiration  Date,  all Options  granted to  Stockholders  under the
Option Plans are vested and  exercisable.  Each  Stockholder  hereby agrees,  if
requested by the Purchaser,  to exercise (on the Expiration Date but not earlier
than 5 p.m.  on such date) all  Options  granted to such  Stockholder  under the
Option Plans,  which exercise may be conditional  upon the  satisfaction  of the
following: the receipt of a notice from the Purchaser that, as of 5 p.m. on such
day, it expects  satisfaction of all conditions in the Offer; the delivery of an
irrevocable  notice by the  Purchaser to the  Depositary of its  acceptance  for
payment of the  tenders of the Shares  pursuant  to the Offer and a  calculation
showing that such exercise and

                                       2
<PAGE>


tender  will,  giving  effect to all Shares  tendered  as of 5 p.m. on such day,
result  in a tender  of over 90% of the  outstanding  Shares  in the  Offer.  In
connection  with such exercise,  the Purchaser  will  indemnify the  Stockholder
against any and all costs, expenses and taxes incurred by such Stockholder which
would not be incurred by such  Stockholder if the Options were treated  pursuant
to Section 2.12(a) of the Merger Agreement.  During the period commencing on the
date hereof and continuing  until the earlier to occur of (i) the Effective Time
and (ii) the  termination of the Merger  Agreement in accordance  with its terms
(such period being referred to as the "Voting  Period"),  each  Stockholder  (x)
hereby  agrees to validly  tender (or cause the record  owner of such  Shares to
validly tender) and sell (and not withdraw) pursuant to the Offer not later than
the tenth business day after  commencement of the Offer all of the Owned Shares;
and (y) at any  meeting  (whether  annual  or  special,  and  whether  or not an
adjourned or postponed meeting) of the Company's  stockholders,  however called,
or in connection with any written consent of the Company's stockholders, subject
to the absence of a preliminary or permanent  injunction or other final order by
any United States  federal,  state or foreign  court barring such action,  shall
vote (or cause to be voted) all of its Owned Shares:

          a. in favor of the Merger,  the  execution and delivery by the Company
     of the Merger Agreement and the approval and adoption of the Merger and the
     terms  thereof  and each of the other  actions  contemplated  by the Merger
     Agreement  and this  Agreement  and any  actions  required  in  furtherance
     thereof and hereof;

          b. against any action or  agreement  that would (A) result in a breach
     of any  covenant,  representation  or warranty or any other  obligation  or

such  Stockholder of the transactions  contemplated  hereby and (ii) none of the
execution and delivery of this Agreement by such  Stockholder,  the consummation
by such  Stockholder of the  transactions  contemplated  hereby or compliance by

violation or breach of, or constitute  (with or without  notice or lapse of time
or both) a  default  (or give  rise to any  third  party  right of  termination,
cancellation,  material  modification or  acceleration)  under any of the terms,
conditions or provisions of any note, loan agreement, bond, mortgage, indenture,
license, contract, commitment,  arrangement,  understanding,  agreement or other
instrument or obligation of any kind to which such  Stockholder is a party or by
which such  Stockholder or any of its properties or assets  (including the Owned
Shares)  may be bound,  or (B)  violate  any order,  writ,  injunction,  decree,
judgment,  statute,  rule or regulation applicable to such Stockholder or any of
