Dear Stockholder:

     You are cordially invited to attend a Special Meeting of stockholders (the
"Special Meeting") of Cellular Communications of Puerto Rico, Inc. (the
"Company") to be held at 10:00 a.m., local time, on Friday, July 16, 1999, at
the offices of Skadden, Arps, Slate, Meagher & Flom LLP, at 919 Third Avenue,
33rd Floor, New York, New York 10022.

     As described in the accompanying Proxy Statement, at the Special Meeting
you will be asked to consider and vote upon a proposal to adopt an Agreement and
Plan of Merger, dated as of April 30, 1999 (the "Merger Agreement"), by and
among SBC Communications Inc. ("SBC"), SBC International-PR, Inc. ("Merger
Subsidiary"), and the Company, pursuant to which Merger Subsidiary will be
merged with and into the Company (the "Merger"), with the Company continuing as
the surviving corporation and becoming a wholly owned subsidiary of SBC.
Pursuant to the Merger Agreement, each share of common stock, par value $.01 per
share, of the Company (including the associated preferred stock purchase right,
a "Share" and, collectively, the "Shares"), other than Shares held by the
Company or any subsidiary thereof or by SBC, Merger Subsidiary or any other
subsidiary of SBC and other than Shares held by the stockholders, if any, who
properly exercise their appraisal rights under Delaware law, will be converted
into the right to receive $29.50 in cash, without interest. Consummation of the
Merger is subject to certain conditions, including adoption of the Merger
Agreement by the affirmative vote of the holders of a majority of the
outstanding Shares.

     Your Board of Directors has carefully reviewed and considered the terms and
conditions of the Merger Agreement and has determined that the Merger Agreement
and the Merger are fair to and in the best interests of the Company and its
stockholders, and has approved the Merger Agreement. In addition, the Company's
financial advisor, Donaldson, Lufkin & Jenrette Securities Corporation, has
rendered its opinion to the effect that, as of the date of such opinion and
based upon and subject to certain matters stated therein, the consideration to
be received by holders of the Shares in the Merger is fair, from a financial
point of view, to such holders.

THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE "FOR" ADOPTION OF THE MERGER
AGREEMENT.

     Detailed information concerning the proposed Merger is set forth in the
accompanying Proxy Statement. I urge you to read the enclosed material carefully
and request that you promptly complete and return the enclosed proxy in the
enclosed return envelope, which requires no postage if mailed in the United
States. If you attend the Special Meeting, you may vote in person even if you
have previously returned your proxy. Your vote is important regardless of the
number of Shares you own.

                                          Sincerely,

                                          /s/ George S. Blumenthal

                           FORWARD-LOOKING STATEMENTS

     Certain information contained or incorporated by reference in this Proxy
Statement, including the information set forth under "Certain Projections of
Future Operating Results" and other statements as to the future financial or
operating performance of the Company, may constitute "forward-looking
statements." When used herein, the words, "believe," "anticipate," "should,"
"intend," "plan," "will," "expects," "estimates," "projects," "positioned,"
"strategy," and similar expressions identify such forward-looking statements.
The Private Securities Litigation Reform Act of 1995 provides certain "safe
harbor" protections for forward-looking statements in order to encourage
companies to provide prospective information about their businesses.
Forward-looking statements include statements concerning plans, objectives,
goals, strategies, future events or performance, and underlying assumptions and
other statements which are other than statements of historical facts.
Forward-looking statements contained or incorporated by reference in this Proxy
Statement were not prepared in compliance with the published guidelines of the
American Institute of Certified Public Accountants regarding projections or
financial forecasts.

     The forward-looking statements set forth or incorporated by reference in
this Proxy Statement are based upon various assumptions, many of which are
based, in turn, upon further assumptions, including without limitation,
management's examination of historical operating trends, data contained in the
Company's records and other data available from third parties. Although the
Company believes that such assumptions were reasonable when made, because such
assumptions are inherently subject to significant uncertainties and
contingencies which are difficult or impossible to predict and are beyond the
Company's control, there can be no assurance, and no representation or warranty
is made, that management's expectations, beliefs or projections will result or
be achieved or accomplished. In addition to the other factors and matters
addressed elsewhere herein and in the documents incorporated by reference
herein, factors that, in the view of the Company, could cause actual results to
differ materially from those discussed in the forward-looking statements
include: general economic and business conditions in Puerto Rico and the U.S.
Virgin Islands, industry trends, the Company's ability to continue to design and
build its network, install facilities, obtain and maintain any required
government licenses or approvals and finance construction and development, all
in a timely manner, at reasonable costs and on satisfactory terms and
conditions, as well as assumptions about customer acceptance, churn rates,
overall market penetration and competition from providers of alternative
services, the impact of new business opportunities requiring significant
up-front investment, Year 2000 readiness, and the availability, terms and
deployment of capital.

     None of the Company, SBC or any of their respective agents, employees or
advisors intends or has any duty or obligation to supplement, amend, update or
revise any of the forward-looking statements contained or incorporated by
reference in this Proxy Statement. Neither the Company's nor SBC's independent

                                 ADOPTION OF THE MERGER AGREEMENT.

                                 In reaching its determination that the Merger
                                 Agreement and the Merger are fair to and in the
                                 best interests of the Company and its
                                 stockholders, the Board considered, among other
                                 things, a number of strategic, financial and
                                 operating factors, as more fully described

                                 Corporation ("DLJ") has delivered its written
                                 opinion to the Board that, as of April 30,
                                 1999, the Merger Consideration to be received

                                 Agreement is fair, from a financial point of
                                 view, to such holders. The full text of the
                                 written opinion of DLJ, which sets forth
                                 assumptions made, matters considered and

                                 reference. The opinion of DLJ referred to
                                 herein does not constitute a recommendation as
                                 to how any stockholder should vote with respect
                                 to the Merger. STOCKHOLDERS ARE URGED TO, AND
                                 SHOULD, READ SUCH OPINION IN ITS ENTIRETY. See

                                 Financial Advisor."

Interests of Certain Persons
in the Merger.................   Certain members of the Company's management and
                                 of the Board will receive economic benefits as

                                 jurisdiction that is in effect and restrains,

                                 and correct, taken together, do not have a

                                 and any state, commonwealth or territorial

                                 reasonably likely to have a Material Adverse
                                 Effect on SBC or the Company, pursuant to a
                                 Final Order (as defined herein); and (iv) the

                                 individually or in the aggregate, is not
                                 reasonably likely to have a Material Adverse
                                 Effect.

                                 The obligations of the Company to effect the

                                       Merger Agreement; and

                                 (v)  by SBC if (A) the Board withdraws or
                                      adversely modifies its approval or
                                      recommendation of the Merger Agreement or
                                      (B) the Company wilfully and materially
                                      breaches the No Solicitation Provision (as
                                      defined herein) which provision is
                                      described in "The Merger
                                      Agreement -- Certain Covenants -- No
                                      Solicitation" or takes any of the actions
                                      that would be proscribed by the No
                                      Solicitation Provision but for the proviso
                                      therein allowing the Company to
                                      participate in negotiations and enter into
                                      agreements regarding acquisition proposals
                                      under certain circumstances.

                                 If the Merger Agreement is terminated by either
                                 the Company or SBC under certain circumstances
                                 described herein, the Company will be obligated
                                 to pay to SBC certain termination fees. See
                                 "The Merger Agreement -- Termination; Certain
                                 Fees."

Certain Federal Income Tax
  Consequences................   The receipt of cash for Shares pursuant to the
                                 Merger will be a taxable transaction for
                                 federal income tax purposes and may also

                                        8
<PAGE>   15

                                 be taxable under applicable state, local and
                                 foreign income and other tax laws. A
                                 stockholder will recognize gain or loss in an
                                 amount equal to the difference between the
                                 adjusted tax basis of his or her Shares and the
                                 amount of cash received in exchange therefor in
                                 the Merger. Such gain or loss will be capital
                                 gain or loss if the Shares are a capital asset
                                 in the hands of the stockholder and will be
                                 long-term capital gain or loss if the holding
                                 period exceeds one year. See "The
                                 Merger -- Certain Federal Income Tax
                                 Consequences."

Accounting Treatment..........   As required by generally accepted accounting
                                 principles ("GAAP"), SBC will use the purchase
                                 method of accounting to account for the Merger.
                                 See "The Merger -- Accounting Treatment."

                              THE SPECIAL MEETING

GENERAL

     This Proxy Statement is being furnished to stockholders of the Company in
connection with the solicitation of proxies by and on behalf of the Board for
use at the Special Meeting to be held at 10:00 a.m., local time, on Friday, July
16, 1999, at the offices of Skadden, Arps, Slate, Meagher & Flom LLP, at 919
Third Avenue, 33rd Floor, New York, New York 10022, and at any adjournments or
postponements thereof. This Proxy Statement and the accompanying Notice and
Proxy Card are first being mailed to stockholders entitled to notice of, and to
vote at, the Special Meeting, on or about June 2, 1999.

MATTERS TO BE CONSIDERED AT THE SPECIAL MEETING

     At the Special Meeting, stockholders of the Company will be asked to
consider and vote upon a proposal to adopt the Merger Agreement. Stockholders
will also be asked to consider and vote upon such other business related to the
proposal to adopt the Merger Agreement as may properly come before the Special
Meeting. The Board has determined that the Merger Agreement and the Merger are
advisable and fair to and in the best interests of the Company and its
stockholders and has approved the Merger Agreement. ACCORDINGLY, THE BOARD
RECOMMENDS THAT STOCKHOLDERS VOTE "FOR" ADOPTION OF THE MERGER AGREEMENT. See
"The Merger -- Background of the Merger" and "-- The Company's Reasons for the
Merger; Recommendation of the Board."

     STOCKHOLDERS ARE REQUESTED TO COMPLETE, DATE, SIGN AND PROMPTLY RETURN THE
ACCOMPANYING PROXY CARD TO THE COMPANY IN THE ENCLOSED POSTAGE-PREPAID ENVELOPE.
FAILURE TO RETURN A PROPERLY EXECUTED PROXY CARD OR TO VOTE AT THE SPECIAL
MEETING WILL HAVE THE SAME EFFECT AS A VOTE "AGAINST" ADOPTION OF THE MERGER
AGREEMENT.

RECORD DATE; VOTING AT THE SPECIAL MEETING

     The Board has fixed June 1, 1999 as the Record Date for the determination
of the stockholders entitled to notice of, and to vote at, the Special Meeting.
Only stockholders of record at the close of business on the Record Date will be
entitled to notice of, and to vote at, the Special Meeting. On the Record Date,
there were 13,441,150 Shares outstanding and entitled to vote at the Special
Meeting, held by approximately 274 stockholders of record.

     Stockholders of record on the Record Date are entitled to one vote per
Share, exercisable in person or by properly executed proxy, upon each matter
properly submitted for the vote of stockholders at the Special Meeting.

REQUIRED VOTE

     The affirmative vote of the holders of a majority of the outstanding Shares
is required to adopt the Merger Agreement. Under applicable Delaware law, in
determining whether the Merger Agreement has received the requisite number of
affirmative votes, abstentions and broker non-votes will be counted as votes
"AGAINST" the proposal to adopt the Merger Agreement. As of the Record Date,
directors and executive officers of the Company and their affiliates were the
beneficial owners of an aggregate of 769,770 (approximately 5.7%) of the Shares
then outstanding and eligible to vote. All such directors and executive officers
are expected to vote their Shares in favor of the Merger Agreement.

QUORUM

     The presence, in person or by properly executed proxy, of the holders of a
majority of the outstanding Shares is necessary to constitute a quorum at the
Special Meeting. Abstentions and broker non-votes will be treated as Shares that
are present and entitled to vote for purposes of determining the presence of a
quorum at the Special Meeting.

                                       11
<PAGE>   18

PROXIES

     All Shares which are represented at the Special Meeting by properly
executed proxies received and not duly and timely revoked will be voted at the
Special Meeting in accordance with the instructions contained therein. In the
absence of contrary instructions, such Shares will be voted "FOR" the adoption
of the Merger Agreement. In addition, the persons designated in such proxies
will have the discretion to vote on matters incident to the conduct of the
Special Meeting.

     A stockholder may revoke a proxy prior to its being voted by: (i)
delivering to the Secretary of the Company, at or before the Special Meeting, a
written instrument bearing a later date than the proxy which instrument, by its
terms, revokes the proxy, (ii) duly executing a subsequent proxy relating to the
same Shares and delivering it to the Secretary of the Company at or before the
Special Meeting, or (iii) attending the Special Meeting and giving notice of
revocation to the Secretary of the Company or in open meeting prior to the proxy
being voted. Attendance at the Special Meeting will not in and of itself
constitute a revocation of a proxy. Any written instrument revoking a proxy
should be sent to: Cellular Communications of Puerto Rico, Inc., 110 East 59th
Street, New York, New York 10022, Attention: Secretary.

     If a quorum is not obtained, or if fewer Shares than the number required
therefor are voted in favor of adoption of the Merger Agreement, it is expected
that the Special Meeting will be postponed or adjourned in order to permit
additional time for soliciting and obtaining additional proxies or votes, and,
at any subsequent reconvening of the Special Meeting, all proxies will be voted
in the same manner as such proxies would have been voted at the original
convening of the Special Meeting, except for any proxies which have theretofore
effectively been revoked or withdrawn. In the absence of a quorum, the Special
Meeting may be adjourned from time to time by the holders of a majority of the
Shares represented at the Special Meeting in person or by proxy.

     Under the Company's bylaws, no business may be transacted at the Special
Meeting other than such business as is designated in the Notice of Special
Meeting of Stockholders.

     The Company will bear the costs of soliciting proxies in the accompanying
form from its stockholders. In addition to soliciting proxies by mail,
directors, officers and employees of the Company, without receiving additional
compensation therefor, may solicit proxies by telephone, by telegram or in
person. Arrangements also will be made with brokerage firms and other
custodians, nominees and fiduciaries to forward solicitation materials to the
beneficial owners of Shares held of record by such persons, and the Company will
reimburse such brokerage firms, custodians, nominees and fiduciaries for
reasonable out-of-pocket expenses incurred by them in connection therewith.

     In addition, the Company has retained D.F. King & Co., Inc. ("D.F. King")
to assist the Company in the solicitation of proxies from stockholders in
connection with the Special Meeting. D.F. King will receive a fee of $5,000.00
as compensation for its services and reimbursement of its out-of-pocket expenses
in connection therewith. The Company has agreed to indemnify D.F. King against
certain liabilities arising out of or in connection with its engagement.

     STOCKHOLDERS SHOULD NOT FORWARD ANY CERTIFICATES REPRESENTING SHARES WITH
THEIR PROXY CARDS. IN THE EVENT THE MERGER IS CONSUMMATED, CERTIFICATES SHOULD
BE DELIVERED IN ACCORDANCE WITH INSTRUCTIONS SET FORTH IN A LETTER OF
TRANSMITTAL WHICH WILL BE SENT TO STOCKHOLDERS PROMPTLY AFTER THE EFFECTIVE
TIME. SEE "THE MERGER AGREEMENT -- THE MERGER -- EXCHANGE OF CERTIFICATES."

                                   THE MERGER

BACKGROUND OF THE MERGER

     In November 1998, the Board authorized management to enter into an
agreement with DLJ pursuant to which the Company engaged DLJ to act as its
exclusive financial advisor with respect to the sale, merger, consolidation or
any other business combination of the Company, in one or a series of
transactions, involving all or a substantial amount of the business securities
or assets of the Company. In January 1999, the Company determined to commence a
private auction process for the sale of the Company.

     From November 1998 through February 1999, DLJ identified parties that might
be interested in engaging in a transaction with the Company and began to contact
such parties, including SBC, in order to ascertain whether such parties would be
prepared to make offers to acquire the Company. During January and February, 27
parties entered into confidentiality agreements with the Company regarding
information provided to them by the Company. During this time, representatives
of SBC indicated an interest in potentially acquiring the Company, and SBC
executed a confidentiality agreement regarding information provided to it by the
Company on January 21, 1999. Confidential information memoranda were distributed
to all parties who entered into confidentiality agreements.

     Interested parties were requested to provide preliminary indications of
interest in participating in the auction, as well as preliminary estimates of
the range of proposed purchase prices. By the end of February 1999, through DLJ,
the Company received preliminary indications of interest from 6 parties. One of
the 6 parties that provided a preliminary indication of interest dropped out of
the auction prior to conducting due diligence.

     From the end of February through the end of March, the remaining 5
interested parties conducted due diligence regarding the Company, attended
management presentations and made site visits to the Company's facilities in
Puerto Rico. During this period, the Company distributed supplemental due
diligence materials to the interested parties.

     During March 1999, the Company sought the advice of its outside legal
counsel, Skadden, Arps, Slate, Meagher & Flom LLP, in the preparation of a
merger agreement to be distributed to interested parties for consideration in
connection with their respective bids to acquire the Company. This draft merger
agreement was distributed to 4 parties on April 6, 1999. One of the 5 parties
conducting due diligence dropped out of the auction process prior to the
distribution of the draft merger agreement. DLJ requested that final proposals
from interested parties be received by April 20, 1999, with such proposals to
include a formal bid letter and a marked version of the proposed merger
agreement indicating the terms on which an interested party would be willing to
consummate a merger with the Company.

     The Company received four proposals. Three proposals were submitted by
financial buyers and provided for leveraged buy-out or recapitalization type
transactions, all of which would involve significant continuing participation by
Company management. SBC was the only strategic purchaser to submit a proposal.
SBC's proposal provided for the purchase of all Shares of the Company at a price
of $28 to $30 per Share through a merger between the Company and a subsidiary of
SBC.

     On April 21, 1999, DLJ met with members of the Company's senior management
and a representative of the Company's legal advisor to discuss and compare the
terms of the four proposals. During the next several days, DLJ contacted parties
as necessary to clarify certain aspects of the proposals. The Board held a
meeting on April 26, 1999, at which it considered the terms of such proposals.
The Board discussed various features of the proposed transactions with members
of senior management as well as the Company's financial and legal advisors.
Since the SBC proposal was the only proposal that provided for the purchase of
all of the Shares pursuant to a transaction that would not require significant
continuing participation by Company management subsequent to the consummation of
such transaction, the Board authorized senior management and the Company's legal
and financial advisors to engage in further negotiations with SBC. Beginning on
April 26, 1999, the legal and financial advisors and the management of both the
Company and SBC commenced

                                       13
<PAGE>   20

negotiation of a definitive merger agreement, based on the proposed merger
agreement that was distributed to interested parties on April 6, 1999 and the
marked version thereof submitted by SBC on April 20, 1999.

     The Board met again on the morning of April 29, 1999, and received a
presentation from DLJ and the Company's management regarding the negotiated
terms of the SBC proposal. At the meeting, DLJ presented its oral opinion
(subsequently confirmed in writing) that the consideration to be received by the
Company's stockholders in the proposed transaction between SBC and the Company
was fair to such stockholders from a financial point of view. The Company's
legal advisors described to the Board the terms of the Merger Agreement. After
questions by the Board to its management and its financial and legal advisors
and further discussions, the Board determined that the SBC proposal as set forth
in the Merger Agreement was advisable and in the best interests of the Company
and its stockholders. The members of the Board (with the exception of Alan J.
Patricof, who was absent) then voted unanimously to approve the Merger Agreement
and the transactions contemplated thereby and to authorize management and the
Company's legal advisors to conclude the drafting and negotiation of the Merger
Agreement.

     The Board of Directors of SBC met on April 30, 1999 for a regularly
scheduled meeting. SBC management described the terms of SBC's proposal and the
Merger Agreement. The Board of Directors of SBC approved SBC's entry into the
Merger Agreement. On the evening of April 30, 1999, after completion of the
drafting of the Merger Agreement, the Company and SBC executed the Merger
Agreement. A joint press release announcing the Merger was issued at 7:00 a.m.
New York time on Monday, May 3, 1999.

THE COMPANY'S REASONS FOR THE MERGER; RECOMMENDATION OF THE BOARD

     Reasons for the Transaction; Factors Considered by the Board.  The Board
and the Company's senior management have reviewed the Company's strategic
position in the Puerto Rican wireless and wireline telephone industry, the
short-term and long-term prospects for that industry, the consolidation trends
within that industry and the strategic alternatives available to the Company,
all with a view to maximizing stockholder value. In conducting its review, the
Board considered the consequences of various transaction structures, the
consequences of remaining an independent company, and recent trading prices of
the Company's Shares. In light of the Board's review of the Company's
competitive position, recent operating results, the stock price, anticipated
trends in the industry in which the Company competes, structural considerations
and the price per Share being offered by SBC, the Board determined that it would
be advisable and in the best interests of the Company's stockholders to adopt
the Merger Agreement. In approving the Merger Agreement and the transactions
contemplated thereby and recommending that all holders of Shares vote to adopt
the Merger pursuant to the terms of the Merger Agreement, the Board considered a
number of factors, including:

          (i) the terms of the Merger Agreement;

          (ii) the trading price of the Shares and the expected trading prices
     for the foreseeable future;

          (iii) the Company's competitive position and current business and
     regulatory trends in the Puerto Rican and United States wireless and
     wireline telephone industries, including the Company's rapid growth in the
     past and the Company's expectation that such rapid growth would continue in
     the future;

          (iv) a range of other possible buyers of the Company that are not
     currently affiliated with SBC including both financial and strategic
     buyers; and

          (v) The opinion of DLJ to the effect that, as of April 30, 1999, and
     based upon and subject to certain matters stated in its opinion, the Merger
     Consideration was fair from a financial point of view to stockholders of
     the Company (a copy of the DLJ opinion, setting forth the assumptions made
     and the limitations on the review undertaken in rendering the opinion, is
     attached as Annex B hereto and is described in "The Merger -- Opinion of
     the Company's Financial Advisor," set forth below.

     In evaluating the Company's strategic position, the Board considered the
potential revenue and cash flow effect of (1) a potential rollout of wireline
fiber-based competitive local exchange services ("CLEC") by the Company and (2)
Calling Party Pays ("CPP") implementation (as reflected in the New Opportunities
Case

                                       14
<PAGE>   21

set forth in the DLJ analysis discussed on page 18), but concluded that there
was (1) substantial uncertainty as to the availability of necessary management
and other resources to implement such a CLEC rollout and (2) uncertainty as to
the timing and terms of pricing and billing arrangements for CPP.

     The full text of the DLJ fairness opinion is attached hereto as Annex B.
The DLJ opinion is addressed to the Board and does not address the merits of the
underlying decision of the Company to engage in the transactions contemplated by
the Merger Agreement or constitute a recommendation to any holder of Shares as
to how such holder should vote at the Special Meeting. The summary of the DLJ
opinion set forth in this Proxy Statement is qualified in its entirety by
reference to the full text of the DLJ opinion. Holders of Shares are urged to
read the DLJ opinion in its entirety.

     The Board did not assign relative weight to the above factors to determine
that any factor was of particular importance. Rather, the Board viewed its
recommendations as being based on the totality of the information presented to
and considered by it.

OPINION OF THE COMPANY'S FINANCIAL ADVISOR

     DLJ has acted as the Company's financial advisor in connection with the
proposed Merger. The Company selected DLJ because DLJ is an internationally
recognized investment banking firm that has substantial experience in the
communications industry and is familiar with the Company and its business. DLJ,
as part of its investment banking business, is regularly engaged in the
valuation of businesses and securities in connection with mergers, acquisitions,
underwritings, sales and distributions of listed and unlisted securities,
private placements and valuations for corporate and other purposes.

     At the meeting of the Board held on April 29, 1999, DLJ delivered to the
Board, subject to its review of the final Merger Agreement, its oral opinion
(which was subsequently confirmed in writing) that, as of such date, and based
upon and subject to the assumptions, limitations and qualifications set forth in
such opinion, the consideration to be received by the Company's stockholders in
the Merger was fair to such holders from a financial point of view.

     The full text of the DLJ opinion is attached as Annex B to this Proxy
Statement. The summary of the DLJ opinion set forth in this Proxy Statement is
qualified in its entirety by reference to the full text of the DLJ opinion.
STOCKHOLDERS ARE URGED TO READ CAREFULLY THE DLJ OPINION IN ITS ENTIRETY. In
reading the discussion of the fairness opinion set forth below, stockholders
should be aware that the DLJ opinion:

     - was prepared for the Board and was directed only to the fairness, from a
       financial point of view to the stockholders, of the Merger Consideration;

     - did not address the relative merits of the Merger, nor of the underlying
       decision by the Board to proceed with the Merger; and

     - does not constitute a recommendation to any stockholder as to how such
       stockholder should vote on the Merger Agreement.

     In arriving at its opinion, DLJ, among other things:

     - reviewed the Merger Agreement;

     - reviewed financial and other information that was publicly available or
       furnished to DLJ by the Company and information provided during
       discussions with the management of the Company, including certain
       financial projections of the Company for the period from January 1, 1999
       to December 31, 2003;

     - compared certain financial and securities data of the Company with other
       companies whose securities are traded in public markets;

     - reviewed the historical stock prices and trading volumes of the Shares;

     - reviewed prices and premiums paid in certain other business combinations;
       and

     - conducted such other financial studies, analyses and investigations as it
       deemed appropriate.

                                       15
<PAGE>   22

     In rendering its opinion, DLJ relied upon and assumed, without independent
verification, the accuracy and completeness of all of the financial and other
information that was available to DLJ from public sources, that was provided to
DLJ by the Company or its representatives, or that was otherwise reviewed by
DLJ. DLJ assumed that the projections supplied to DLJ by the Company's
management were reasonably prepared on a basis reflecting the best currently
available estimates and judgements of the management as to the future operating
and financial performance of the Company. DLJ did not assume any responsibility
for making an independent valuation or appraisal of the assets or liabilities of
the Company and was not furnished with any such evaluation or appraisal.

     The DLJ opinion is necessarily based on economic, market, financial and
other conditions as they existed on, and on the information made available to
DLJ as of, the date of the opinion. The DLJ opinion states that DLJ does not
have any obligation to update, revise or reaffirm its opinion even though it may
be affected by subsequent developments.

  FINANCIAL ANALYSIS

     The following is a brief summary of the material financial analyses
presented by DLJ to the Board on April 29, 1999 in connection with the rendering
of the DLJ opinion.

     Special Considerations.  In presenting to the Board the analyses described
below, DLJ reviewed several factors which would depress the equity value per
Share below the values implied by these analyses, including: (a) the Company's
comparatively reduced opportunities for generating roaming revenues, which are
attributable to the geographical characteristics of its service area, (b) the
highly competitive environment in the wireless communications sector in Puerto
Rico, and (c) the portion of the Company's revenues attributable to paging
services, which generally carry lower multiples than cellular revenues.

     Indexed Stock Price Histories.  DLJ reviewed the daily indexed common stock
price history for the Company for the period from September 3, 1998 to April 26,
1999. The analysis indicated that the price performance of the Shares had, prior
to the announcement that the Company had hired an investment bank to review
strategic alternatives, tended to lag the performance of the S&P 400 and the
Wireless Composite index (which includes Price Communications Corp., Rural
Cellular Corp., and United States Cellular Corp.).

     Analysis of Selected Publicly Traded Companies.  DLJ compared certain
financial, market and operating information of the Company with corresponding
data of the following selected publicly traded companies: Price Communications
Corp., Rural Cellular Corp., United States Cellular Corp., Commnet Cellular and
Centennial Cellular Corp. DLJ chose the first three of these (the "Selected
Companies") because it believed they were the most comparable to the Company,
and analyzed their enterprise values (defined as the value of fully diluted
common equity plus long-term debt and the liquidation value of outstanding
preferred stock, if any, minus cash, the proceeds, if any, from the exercise of
outstanding options and warrants and the value of certain other assets) as a
multiple of each company's respective latest quarter annualized earnings before
interest, taxes, depreciation and amortization (" EBITDA"), estimated 1999
EBITDA and estimated 2000 EBITDA, to the extent these EBITDA figures were
available from research analyst reports. The following table presents the
ranges, medians and means yielded by DLJ's analysis of the Selected Companies.

     DLJ then applied the median and average multiples of estimated 1999 and
2000 EBITDA for the Selected Companies to the Company's estimated 1999 and 2000
EBITDA to calculate an implied equity value per Share, as summarized in the

     Selected Transactions Analysis.  DLJ reviewed the implied transaction
multiples paid in the following announced and completed merger and acquisition
transactions in the communications industry (acquiror/ target): AT&T/Honolulu
Cellular, GTE/Ameritech Wireless Assets, SBC Communications/Comcast Cellular
Corp., Vodafone/AirTouch Communications, ALLTELL/Alliant Communications, AT&T/
Vanguard Cellular, Welsh, Carson, Anderson & Stowe/Centennial Cellular Corp.,
Dobson Communications/ Sygnet Wireless, ALLTELL/360 Communications, American
Cellular Corp./PriCellular Corp., Rural Cellular Corporation/Atlantic Cellular,
Wireless One/Price Comm. (Ft. Myers), Blackstone Capital Partners/Commnet
Cellular, Price Communications/Palmer Wireless, Western Wireless/Triad Cellular
Corp., AirTouch Communications/US West, and 360 Communications/Independent
Cellular Network. In examining these acquisitions, DLJ calculated the enterprise
value of the acquired company implied by each of these transactions (a) as a
multiple of the latest quarter annualized EBITDA and of estimated forward EBITDA
(for the fiscal year following the announcement of the transaction as obtained
by DLJ from various publicly available sources), and (b) per POP, in each case
to the extent the necessary information was publicly available. DLJ also
performed this analysis on a selection of the above transactions that it
believed were most comparable to the Merger, comprised of GTE/Ameritech Wireless
Assets, SBC Communications/ Comcast Cellular and AT&T/Vanguard Cellular (the
"Selected Transactions"). The results of these analyses are summarized in the
following table:

     DLJ then calculated implied equity values per Share by applying the median

     Premiums Paid Analysis.  DLJ determined the implied premium over the common
stock trading prices for one day, one week and four weeks prior to announcement
dates of all domestic acquisitions announced between June 1, 1995 and March 31,
1999 with a transaction value between $500 million and $1 billion. DLJ then
calculated implied equity values per Share by applying the range of premiums
paid in these transactions to the price per Share (a) as of one day, one week
and four weeks prior to its November 13, 1998 announcement that it intended to
hire an investment bank to review strategic alternatives, and (b) as of one day,
one week and four weeks prior to April 27, 1999. The following table summarizes
the range of implied equity values per Share resulting from this analysis:

     Discounted Cash Flow Analysis.  DLJ performed an analysis of the present
value of the cash flows that could be produced by the Company, based on (i)
projections and assumptions used in conjunction with the bank financing
undertaken in August 1998 in connection with the spinoff of CoreComm Limited
(the "Bank Case"), (ii) projections and assumptions provided by the Company's
management reflecting new opportunities available to the Company (the "New
Opportunities Case"), and (iii) certain sensitivities to the New Opportunities
Case based on discussions with Company management that assumed, among other
things, no EBITDA and revenue growth from the new opportunities (the "Base
Case"). The net present value ranges were estimated using discount rates ranging
from 15% to 20% and terminal multiples of estimated EBITDA for the Company's
fiscal year 2003 ranging from 7.5x to 9.5x. DLJ also made use of a discounted
cash flow analysis performed by a DLJ equity analyst (the "Research Case"). The
ranges of implied equity values per Share yielded by these analyses are
summarized in the following table:

     The summary set forth above does not purport to be a complete description
of the analyses performed by DLJ. The preparation of a fairness opinion involves
various determinations as to the most appropriate and relevant methods of
financial analysis and the application of these methods to the particular
circumstances and, therefore, such an opinion is not readily susceptible to
summary description. Each of the analyses conducted by DLJ was carried out in
order to provide a different perspective on the Merger. DLJ did not form a
conclusion as to whether any individual analysis, considered in isolation,
supported or failed to support an opinion as to fairness from a financial point
of view. Rather, in reaching its conclusions, DLJ considered the results of the
analyses in light of each other and ultimately reached its opinion based on the
results of all analyses taken as a whole. Accordingly, taking portions of the
analyses set forth above, without considering the analyses as a whole, would, in
the view of DLJ, create an incomplete view of the evaluation process underlying
its opinion. The analyses performed by DLJ are not necessarily indicative of
actual value or future results, which may be significantly more or less
favorable than suggested by such analyses.

     Pursuant to the terms of an engagement letter dated December 16, 1998, the
Company agreed to pay to DLJ (a) a fee of $250,000, payable upon execution of
the engagement letter, (b) a fee of $2,000,000 at the time DLJ notified the
Board that it was prepared to deliver the DLJ opinion, and $100,000 for each
update of a DLJ opinion, and (c) additional cash compensation, payable upon
consummation of a transaction (defined in the engagement letter as the sale,
merger, consolidation or any other business combination involving all or a

                                       18

substantial amount of the business, securities or assets of the Company), equal
to seven tenths of one percent of the aggregate value of (i) the outstanding
Shares (treating any Shares issuable upon exercise of options, warrants or other
rights of conversion as outstanding) and (ii) the amount of any debt assumed,
acquired, remaining outstanding, retired or defeased or preferred stock redeemed
or remaining outstanding in connection with a transaction, less amounts paid to
DLJ pursuant to (a) and (b) above. In addition, the Company agreed to reimburse
DLJ, upon request by DLJ from time to time, for all reasonable out-of-pocket
expenses (including the reasonable fees and expenses of counsel) incurred by DLJ
in connection with its engagement, and to indemnify DLJ and certain related
persons against certain liabilities in connection with the engagement, including
liabilities under U.S. federal securities laws. DLJ and the Company management
negotiated the terms of the fee arrangement, and the Company Board was aware of
such arrangement, including the fact that a significant portion of the aggregate
fee payable to DLJ is contingent upon the consummation of a transaction.

     In the ordinary course of business, DLJ and its affiliates may own or
actively trade the securities of the Company for their own accounts and for the
accounts of their customers, and, accordingly, may at any time hold a long or
short position in the Company securities. DLJ has performed investment banking
and other services for the Company, its affiliates and former affiliates
(including NTL Incorporated, Cellular Communications International, Inc., OCOM
Corporation and Corecomm Limited) in the past and has received customary
compensation for such services.

INTERESTS OF CERTAIN PERSONS IN THE MERGER

     In considering the recommendation of the Board with respect to the Merger,
stockholders of the Company should be aware that certain directors and executive
officers of the Company may be deemed to have interests in the Merger in
addition to their interests as stockholders of the Company generally. The Board
was aware of these interests and considered them, in conjunction with other
factors, in approving the Merger Agreement. These interests are summarized
below.

     Interests in Shares and Options.  As of June 1, 1999, the executive
officers and directors of the Company owned an aggregate of 769,770 Shares. The
aggregate consideration which would be received in the Merger by the executive
officers and directors of the Company in respect of such Shares is
$22,708,215.00.

     In addition, as of June 1, 1999, the executive officers and directors of
the Company had present and future rights to acquire 1,706,607 Shares upon the
exercise of Options granted to such executive officers and directors pursuant to
the Company's stock option plans. Pursuant to the Merger Agreement, each holder
of any Option, whether or not then vested or exercisable, will be paid as soon
as practicable after the Effective Time, in settlement and cancellation of such
Option, an amount determined by multiplying (i) the excess, if any, of the
Merger Consideration over the applicable exercise price of such Option, by (ii)
the number of Shares such holder could have purchased (assuming full vesting of
all Options) had such holder exercised such Option in full immediately prior to
the Effective Time, subject in case of payment to any such holder's signing a
release by which the holder relinquishes all rights with respect to the Options
upon payment in settlement and cancellation of such Options. The cash which
would be received by the executive officers and directors of the Company upon
consummation of the Merger pursuant to the foregoing formula would be
approximately $83,609,200.00. See "The Merger Agreement -- The
Merger -- Treatment of Stock Options."

     Indemnification and Insurance.  Pursuant to the Merger Agreement, SBC has
agreed that for a period of six years after the Effective Time, it will, and
will cause the Surviving Corporation to, (i) indemnify and hold harmless each
person who, prior to the Effective Time, was an officer, director or employee of
the Company or any of its subsidiaries (the "Indemnitees") against all losses,
reasonable expenses, claims, damages or liabilities incurred in connection with
any claim, action, suit or proceeding arising out of acts or omissions occurring
at or prior to the Effective Time (including, without limitation, in respect of
acts or omissions in connection with the Merger Agreement and the transactions
contemplated thereby) to the fullest extent permitted or required under
applicable law and (ii) advance to such Indemnitees expenses (including
attorneys' fees) incurred in defending any action or suit with respect to such
matters (including the cost of any investigation and preparation incurred in
connection therewith), in each case to the fullest extent such

                                       19
<PAGE>   26

Indemnitees are entitled to advancement of expenses under and subject to the
terms of the Company's certificate of incorporation and by-laws or the
certificate of incorporation and by-laws of any subsidiary of the Company (if
the Indemnitee was acting in such Indemnitee's capacity as an officer, director
or employee). The Merger Agreement provides that to the extent permitted by the
DGCL, such advancement of expenses shall be mandatory rather than permissive.

     In addition, SBC has agreed that for a period of six years after the
Effective Time it will, and will cause the Surviving Corporation to, provide
officers' and directors' liability insurance in respect of acts or omissions
occurring prior to the Effective Time covering each such person currently
covered by the Company's officers' and directors' liability insurance policy
("D&O Insurance") on terms with respect to coverage and amount no less favorable
than those of such policy in effect on the date of the Merger Agreement,
provided that in no event shall the annual premium therefor exceed 150% of the
annual premium payable pursuant to the renewal policy disclosed to SBC (the
"Current Premiums"); provided, however, that if the existing D&O Insurance
expires, is terminated or cancelled during such six-year period, the Surviving
Corporation is required pursuant to the Merger Agreement to use its reasonable
best efforts to obtain as much D&O Insurance as can be obtained for the
remainder of such period for a premium not in excess (on an annualized basis) of
150% of the Current Premium. SBC has agreed that, should the Surviving
Corporation fail to comply with such obligations, SBC will be responsible
therefor to the extent permitted under Delaware law. See "The Merger
Agreement -- Certain Covenants -- Indemnification and Insurance."

     Benefit Plans.  Pursuant to the Merger Agreement, SBC has agreed that, for
a period of one year after the Closing Time, it will cause the Surviving
Corporation and its subsidiaries to provide to all active employees of the
Company who continue to be employed by the Company as of the Effective Time
coverage by benefit plans or arrangements which are, in the aggregate, no less
favorable than those provided to the employees immediately prior to the Closing
Time with the exception of any stock option, stock purchase or other stock
compensation plan. See "The Merger Agreement -- Certain Covenants -- Employee
Matters."

     Severance Arrangements.  The severance policy adopted by the Board provides
for severance benefits to Puerto Rico resident employees of the Company and,
accordingly, applies to Steve Shapiro, Senior Vice President-General Manager of
the Company, and Jose J. Davila, Vice President-Finance of Services of the
Company, both of whom are Puerto Rico residents. Under the severance policy,
$365,481.55, in the aggregate, may become payable to them in connection with the
Merger. Under the laws of the Commonwealth of Puerto Rico, Messrs. Shapiro and
Davila would also be entitled to certain severance payments.

     Pursuant to the Merger Agreement, SBC has agreed that, for a period of one
year, it shall provide to all active employees of the Company at the Closing
Time, benefits no less favorable in the aggregate than those provided under the
severance policy adopted by the Board with respect to Puerto Rico resident
employees. See "The Merger Agreement -- Certain Covenants -- Employee Matters."

FINANCING THE MERGER

     The Merger is not subject to any financing contingency. SBC intends to use
working capital to finance the Merger Consideration.

ACCOUNTING TREATMENT

     The Merger will be accounted for by SBC as a "purchase" in accordance with
GAAP. Therefore, the aggregate consideration paid by SBC in connection with the
Merger will be allocated to the Company's assets and liabilities based upon
their fair values, with any excess being allocated to goodwill. The assets and
liabilities and results of operations of the Company will be consolidated into
the assets and liabilities and results of operations of SBC subsequent to the
consummation of the Merger.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

     The following discussion describes certain United States federal income tax
consequences relevant to the Merger. The discussion is based upon the Internal
Revenue Code of 1986, as amended (the "Code"), existing

                                       20
<PAGE>   27

and proposed Treasury regulations promulgated thereunder, rulings,
administrative pronouncements and judicial decisions, changes to which could
materially affect the tax consequences described herein and could be made on a
retroactive basis.

     The receipt of cash in exchange for Shares pursuant to the Merger will be a
taxable transaction for federal income tax purposes and may also be a taxable
transaction under applicable state, local and foreign income and other tax laws.
The tax consequences of such receipt may vary depending upon, among other
things, the particular circumstances of the stockholder. In general, a
stockholder will recognize gain or loss for federal income tax purposes equal to
the difference between the adjusted tax basis of his or her Shares and the
amount of cash received in exchange therefor in the Merger. Gain or loss should
be computed separately for different blocks of Shares (Shares acquired at the
same time and price). Such gain or loss will be capital gain or loss if the
Shares are a capital asset in the hands of the stockholder.

     Under recently adopted amendments to the Code, net capital gain (i.e.,
generally capital gain in excess of capital loss) recognized by an individual
investor upon a disposition of Shares that have been held for more than one year
at the Effective Time will generally be subject to a maximum tax rate of 20% or,
in the case of Shares that have been held for one year or less at the Effective
Time, will be subject to tax at ordinary income tax rates.

     The receipt of cash by a stockholder of the Company pursuant to the Merger
may be subject to a 31% backup withholding tax unless the stockholder (i) is a
corporation or comes within certain other exempt categories or (ii) provides a
certified taxpayer identification number on Form W-9 and otherwise complies with
the backup withholding rules. Backup withholding is not an additional tax; any
amounts so withheld may be credited against the federal income tax liability of
the stockholder subject to the withholding.

     The foregoing discussion does not address all aspects of federal income
taxation that may be relevant to a stockholder and may not apply, for example,
to stockholders who (i) acquired their Shares pursuant to the exercise of
employee stock options or other compensation arrangements with the Company, (ii)
are not citizens or residents of the United States, (iii) perfect their
Appraisal Rights or (iv) are subject to special tax treatment under the Code
(such as dealers in securities, traders in securities that elect to mark to
market, insurance companies, other financial institutions, regulated investment
companies, stockholders that hold Shares as parts of a straddle, hedge against
currency risk, constructive sale or conversion transaction, stockholders that
have a functional currency other than the U.S. dollar and tax-exempt entities).

     THE TAX DISCUSSION SET FORTH ABOVE IS INCLUDED FOR GENERAL INFORMATION
ONLY. DUE TO THE INDIVIDUAL NATURE OF TAX CONSEQUENCES, STOCKHOLDERS ARE URGED
TO CONSULT THEIR TAX ADVISORS AS TO THE SPECIFIC TAX CONSEQUENCES TO THEM OF THE
MERGER, INCLUDING THE EFFECTS OF APPLICABLE STATE, LOCAL OR FOREIGN INCOME OR
OTHER TAX LAWS.

REGULATORY FILINGS AND APPROVALS

     The regulatory filings and approvals described below must be made before
the Merger can be effected and certain of such approvals may take a significant
period of time to obtain. Although the Company and SBC believe that such
approvals will be obtained, there can be no assurance that this will be the case
or that such approvals will be obtained in a timely manner or will not be
conditioned temporarily or otherwise encumbered.

     FCC.  Before the Merger can be consummated, the Company and SBC must obtain
the approval of the FCC pursuant to the Communications Act of 1934, as amended
(the "Communications Act"), for the transfer of control of authorizations issued
by the FCC, including cellular, paging and microwave licenses and international
long distance resale authorizations currently held by subsidiaries of the
Company. The FCC will evaluate whether SBC is qualified to control the
authorizations and whether the public interest, convenience, and necessity will
be served by the transfer of control that will take place upon consummation of
the Merger. The FCC will issue a public notice of the applications filed by the
Company and SBC, and interested parties may notify the FCC of their support for
or opposition to the Merger. On July 24, 1998, in connection with the merger of
Ameritech Corporation ("Ameritech") with a wholly owned subsidiary of SBC, SBC
and Ameritech filed applications with the FCC seeking consent to the transfer of
control of licenses held by Ameritech to SBC. A number of parties have either
opposed the merger of SBC and Ameritech or requested

                                       21
<PAGE>   28

the FCC to impose various conditions on approval of the merger. On March 26,
1999, the FCC published notice of applications seeking the FCC's consent to the
transfer of control of cellular and other licenses from Comcast Cellular
Holdings Co. ("Comcast") to SBC. Both the Ameritech and Comcast applications
remain pending. The time for filing oppositions or comments regarding the
Comcast transfer applications has expired and no oppositions or comments were
filed. The Company and SBC expect that the applications they intend to file with
the FCC will demonstrate compliance with the FCC's standards and the public
interest. However, there can be no assurance as to when and if the required FCC
approvals will be obtained. In addition there can be no assurance that the FCC
will not impose conditions on its approvals that could create problems with the
Merger.

     At the time that SBC and the Company entered into the Merger Agreement, it
was contemplated that Telefonos de Mexico, S.A. de C.V., a corporation organized
under the laws of Mexico ("Telmex"), would purchase an interest in the Surviving
Corporation. Pursuant to certain agreements entered into between SBC
International, Inc. ("SBCI"), a wholly owned subsidiary of SBC and the entity
through which SBC intends to hold its interest in the Surviving Corporation, and
Telmex, immediately following the consummation of the Merger, SBCI will sell to
Telmex 25% of the common stock of SBC International Puerto Rico, Inc.
("SBC-PR"), a Delaware corporation and a wholly owned subsidiary of SBCI, which
will own 100% of the common stock of the Surviving Corporation (the "Telmex
Transaction"). SBCI has further agreed to sell an additional 25% of the common
stock of SBC-PR to Telemex, with such sale conditioned upon the FCC permitting
Telmex, as a corporation organized under the laws of a foreign country, to own
more than 25% of the capital stock of the SBC-PR.

     Antitrust.  The Merger is subject to the requirements of the HSR Act, and
the rules and regulations thereunder, which provide that certain transactions
may not be consummated until required information and materials are furnished to
the Antitrust Division of the Department of Justice (the "Antitrust Division")
and the Federal Trade Commission (the "FTC"), and the requisite waiting period
expires or terminates. The Company and SBC expect to make all filings required
by the Antitrust Division and the FTC on or about June 7, 1999, commencing a
30-day waiting period. Regardless of whether the waiting period expires or is
terminated pursuant to early termination under the HSR Act, at any time before
or after the Effective Time, the Antitrust Division or the FTC could take such
action under the antitrust laws as either of them deems necessary or desirable
in the public interest, or certain other persons could take action under the
antitrust laws, including seeking to enjoin the Merger. See "The Merger
Agreement -- Certain Covenants -- Certain Filings, Consents and Arrangements."

EFFECT OF MERGER ON THE CREDIT AGREEMENT OF CCPR SERVICES, INC. AND CCPR, INC.

     The Company has outstanding $155,000,000 under the Credit Agreement (the
"Credit Agreement") dated as of August 11, 1998 between CCPR Services, Inc.,
CCPR, Inc. (formerly known as Cellular Communications of Puerto Rico, Inc.),
certain subsidiaries of CCPR, Inc. party thereto as guarantors, the various
lenders party thereto and The Chase Manhattan Bank, as administrative agent. The
occurrence of a change in control constitutes an event of default under the
Credit Agreement. A change of control under the Credit Agreement shall be deemed
to have occurred in the event of the acquisition by any person of Shares
representing more than 40% of the aggregate ordinary voting power represented by
the issued and outstanding Shares. Accordingly, unless prior to the Effective
Time the Credit Agreement is amended to provide otherwise, any amounts
outstanding under the Credit Agreement shall become due and payable immediately
upon consummation of the Merger.

CERTAIN CONSEQUENCES OF THE MERGER

     Pursuant to the Merger Agreement, Merger Subsidiary will be merged with and
into the Company and the Company will become a wholly owned subsidiary of SBC
and, upon consummation of the Telmex Transaction, an indirect subsidiary of SBC
and Telmex. See "The Merger -- Regulatory Filings and Approvals -- FCC."
Following consummation of the Merger, the Shares will be delisted from the
Nasdaq, deregistered under the Exchange Act and will no longer be publicly
traded. See "The Merger Agreement -- The Merger."

APPRAISAL RIGHTS

     Under the DGCL, any stockholder who does not wish to accept the Merger
Consideration has the right to dissent from the Merger and to seek an appraisal
of, and to be paid the fair value (exclusive of any element of value arising
from the accomplishment or expectation of the Merger) for, the Shares, provided
that the stockholder complies with the provisions of Section 262 of the DGCL.

     Holders of record of the Shares who do not vote in favor of the Merger
Agreement and who otherwise comply with the applicable statutory procedures
summarized herein will be entitled to Appraisal Rights under Section 262 of the
DGCL. A person having a beneficial interest in Shares held of record in the name
of another person, such as a broker or nominee, must act promptly to cause the
record holder to follow the steps summarized below properly and in a timely
manner to perfect Appraisal Rights.

     THE FOLLOWING DISCUSSION IS NOT A COMPLETE STATEMENT OF THE LAW PERTAINING
TO APPRAISAL RIGHTS UNDER THE DGCL AND IS QUALIFIED IN ITS ENTIRETY BY THE FULL
TEXT OF SECTION 262 OF THE DGCL WHICH IS REPRINTED IN ITS ENTIRETY AS ANNEX C
ATTACHED HERETO. ALL REFERENCES IN SECTION 262 OF THE DGCL AND IN THIS SUMMARY
TO A "STOCKHOLDER" OR "HOLDER" ARE TO THE RECORD HOLDER OF THE SHARES AS TO
WHICH APPRAISAL RIGHTS ARE ASSERTED.

     Under Section 262 of the DGCL, holders of Dissenting Shares who follow the
procedures set forth in Section 262 of the DGCL will be entitled to have their
Dissenting Shares appraised by the Delaware Chancery Court and to receive
payment in cash of the "fair value" of such Dissenting Shares, exclusive of any
element of value arising from the accomplishment or expectation of the Merger,
together with a fair rate of interest, if any, as determined by such court.

     Under Section 262 of the DGCL, where a proposed merger is to be submitted
for approval at a meeting of stockholders, the corporation, not less than 20
days prior to the meeting, must notify each of its stockholders who was a
stockholder on the record date for such meeting with respect to shares for which
Appraisal Rights are available, that Appraisal Rights are so available, and must
include in such notice a copy of Section 262 of the DGCL.

     This Proxy Statement constitutes such notice to the holders of Dissenting
Shares and the applicable statutory provisions of the DGCL are attached to this
Proxy Statement as Annex C. Any stockholder who wishes to exercise such
Appraisal Rights or who wishes to preserve his or her right to do so should
review the following discussion and Annex C carefully, because failure timely
and properly to comply with the procedures therein specified will result in the
loss of Appraisal Rights under the DGCL.

     A holder of Dissenting Shares wishing to exercise such holder's Appraisal
Rights (i) must not vote in favor of the Merger Agreement and (ii) must deliver
to the Company prior to the vote on the Merger Agreement at the Special Meeting,
a written demand for appraisal of such holder's Dissenting Shares. This written
demand for appraisal must be in addition to and separate from any proxy or vote
abstaining from or against the Merger. This demand must reasonably inform the
Company of the identity of the stockholder and of the stockholder's intent
thereby to demand appraisal of his or her Shares. A holder of Dissenting Shares
wishing to exercise such holder's Appraisal Rights must be the record holder of
such Dissenting Shares on the date the written demand for appraisal is made and
must continue to hold such Dissenting Shares until the consummation of the
Merger. Accordingly, a holder of Dissenting Shares who is the record holder of
Dissenting Shares on the date the written demand for appraisal is made, but who
thereafter transfers such Dissenting Shares prior to consummation of the Merger,
will lose any right to appraisal in respect of such Dissenting Shares.

     Only a holder of record of Dissenting Shares is entitled to assert
Appraisal Rights for the Dissenting Shares registered in that holder's name. A
demand for appraisal should be executed by or on behalf of the holder of record,
fully and correctly, as such holder's name appears on such holder's stock
certificates. If the Dissenting Shares are owned of record in a fiduciary
capacity, such as by a trustee, guardian or custodian, execution of the demand
should be made in that capacity, and if the Dissenting Shares are owned of
record by more than one owner as in a joint tenancy or tenancy in common, the
demand should be executed by or on behalf of all joint owners. An authorized
agent, including one or more joint owners, may execute a demand for appraisal on
behalf of a holder of record; however, the agent must identify the record owner
or owners and

                                       23
<PAGE>   30

expressly disclose the fact that, in executing the demand, the agent is agent
for such owner or owners. A record holder such as a broker who holds Dissenting
Shares as nominee for several beneficial owners may exercise Appraisal Rights
with respect to the Dissenting Shares held for one or more beneficial owners
while not exercising such rights with respect to the Dissenting Shares held for
other beneficial owners; in such case, the written demand should set forth the
number of Dissenting Shares as to which appraisal is sought. When no number of
Dissenting Shares is expressly mentioned, the demand will be presumed to cover
all Dissenting Shares in brokerage accounts or other nominee forms and those who
wish to exercise Appraisal Rights under Section 262 of the DGCL are urged to
consult with their brokers to determine the appropriate procedures for the
making of a demand for appraisal by such a nominee.

     ALL WRITTEN DEMANDS FOR APPRAISAL SHOULD BE SENT OR DELIVERED TO CELLULAR
COMMUNICATIONS OF PUERTO RICO, INC., 110 EAST 59TH STREET, NEW YORK, NEW YORK
10022, ATTENTION: SECRETARY.

     Within 10 days after the consummation of the Merger, the Company will
notify each stockholder who has properly asserted Appraisal Rights under Section
262 of the DGCL and has not voted in favor of the Merger Agreement of the date
the Merger became effective.

     Within 120 days after the consummation of the Merger, but not thereafter,
the Company or any stockholder who has complied with the statutory requirements
summarized above may file a petition in the Delaware Chancery Court demanding a
determination of the fair value of the Dissenting Shares. The Company is under
no obligation to and has no present intention to file a petition with respect to
the appraisal of the fair value of the Dissenting Shares. Accordingly, it is the
obligation of stockholders wishing to assert Appraisal Rights to initiate all
necessary action to perfect their Appraisal Rights within the time prescribed in
Section 262 of the DGCL.

     Within 120 days after the consummation of the Merger, any stockholder who
has complied with the requirements for exercise of Appraisal Rights will be
entitled, upon written request, to receive from the Company a statement setting
forth the aggregate number of Dissenting Shares not voted in favor of adoption
of the Merger Agreement and with respect to which demands for appraisal have
been received and the aggregate number of holders of such Dissenting Shares.
Such statements must be mailed within 10 days after a written request therefor
has been received by the Company.

     If a petition for an appraisal is filed timely, after a hearing on such
petition, the Delaware Chancery Court will determine the stockholders entitled
to Appraisal Rights and will appraise the "fair value" of their Dissenting
Shares, exclusive of any element of value arising from the accomplishment or
expectation of the Merger, together with a fair rate of interest, if any, to be
paid upon the amount determined to be the fair value. Stockholders considering
seeking appraisal should be aware that the fair value of their Dissenting Shares
as determined under Section 262 of the DGCL could be more than, the same as or
less than the value of the consideration they would receive pursuant to the
Merger Agreement if they did not seek appraisal of their Dissenting Shares and
that investment banking opinions as to fairness from a financial point of view
are not necessarily opinions as to fair value under Section 262 of the DGCL. The
Delaware Supreme Court has stated that "proof of value by any techniques or
methods which are generally considered acceptable in the financial community and
otherwise admissible in court" should be considered in the appraisal
proceedings.

     The Delaware Chancery Court will determine the amount of interest, if any,
to be paid upon the amounts to be received by stockholders whose Dissenting
Shares have been appraised. The costs of the action may be determined by the
Delaware Chancery Court and taxed upon the parties as the Delaware Chancery
Court deems equitable. The Delaware Chancery Court may also order that all or a
portion of the expenses incurred by any stockholder in connection with an
appraisal, including, without limitation, reasonable attorneys' fees and the
fees and expenses of experts utilized in the appraisal proceeding, be charged
pro rata against the value of all of the Dissenting Shares entitled to
appraisal.

     Any holder of Dissenting Shares who has duly demanded an appraisal in
compliance with Section 262 of the DGCL will not, after the consummation of the
Merger, be entitled to vote the Dissenting Shares subject to such demand for any
purpose or be entitled to the payment of dividends or other distributions on
those

                                       24
<PAGE>   31

Dissenting Shares (except dividends or other distributions payable to holders of
record of Dissenting Shares as of a record date prior to the consummation of the
Merger).

     If any stockholder who properly demands appraisal of his or her Dissenting
Shares under Section 262 of the DGCL fails to perfect, or effectively withdraws
or loses, his or her right to appraisal, as provided in Section 262 of the DGCL,
the Dissenting Shares of such stockholder will be converted into the right to
receive the consideration receivable with respect to such Dissenting Shares in
accordance with the Merger Agreement. A stockholder will fail to perfect, or
effectively lose or withdraw, his or her right to appraisal if, among other
things, no petition for appraisal is filed within 120 days after the
consummation of the Merger, or if the stockholder delivers to the Company a
written withdrawal of his or her demand for appraisal. Any such attempt to
withdraw an appraisal demand more than 60 days after the consummation of the
Merger will require the written approval of the Company.

     Failure to follow the steps required by Section 262 of the DGCL for
perfecting Appraisal Rights may result in the loss of such rights (in which
event a stockholder will be entitled to receive the consideration receivable
with respect to his or her Dissenting Shares in accordance with the Merger
Agreement).

                              THE MERGER AGREEMENT

     The following is a brief summary of certain material provisions of the
Merger Agreement which is attached as Annex A to this Proxy Statement and
incorporated herein by reference. Such summary does not purport to be complete
and is qualified in its entirety by reference to the Merger Agreement.
Stockholders are urged to review the Merger Agreement carefully and in its
entirety.

THE MERGER

     General.  The Merger Agreement provides, among other things, that,
following the adoption of the Merger Agreement by the stockholders of the
Company and the satisfaction or waiver of the other conditions to the Merger,
Merger Subsidiary will be merged with and into the Company, the separate
existence of Merger Subsidiary will cease and the Company will be the Surviving
Corporation. As a result of the Merger, all the rights, privileges, immunities,
powers and franchises of the Company and Merger Subsidiary will vest in the
Surviving Corporation and all obligations, duties, debts and liabilities of the
Company will become the obligations, duties, debts and liabilities of the
Surviving Corporation.

     Closing.  The Merger Agreement provides that the closing of the Merger (the
"Closing") will take place on a date specified by the parties thereto, which
shall be no later than 10:00 a.m., eastern time, on the third business day after
the satisfaction or waiver of all conditions to the Merger (the "Closing Time").
At the Closing, the Company, SBC and Merger Subsidiary will cause a certificate
of merger (the "Certificate of Merger") to be filed with the Secretary of State
of the State of Delaware, and the Merger will become effective upon such filing
or at such later time as is specified in the Certificate of Merger.

     Treatment of Stock Options.  Immediately prior to the Effective Time, each
outstanding Option to purchase Shares granted under any employee or director
stock option or compensation plan or arrangement of the Company will be
canceled, and the Company will pay to each holder of any such Option, whether or
not then vested or exercisable, as soon as practicable after the Effective Time,
for each such Option an amount determined by multiplying (i) the excess, if any,
of the Merger Consideration over the applicable exercise price of such Option,
by (ii) the number of Shares such holder could have purchased (assuming full
vesting of all Options) had such holder exercised such Option in full
immediately prior to the Effective Time, subject in case of payment to any such
holder's signing a release as contemplated by the Merger Agreement.

     Conversion of Securities.  Each Share issued and outstanding immediately
prior to the Effective Time, other than the Excluded Shares which will
automatically be canceled and retired, will be converted into the right to
receive the Merger Consideration, which is the right to receive $29.50 per Share
in cash, without interest. Each share of common stock, par value $1.00 per
share, of Merger Subsidiary issued and outstanding immediately prior to the
Effective Time will be converted into and become one share of common stock, par
value $.01 per share, of the Surviving Corporation with the same rights, powers
and privileges as the shares so converted and will constitute the only
outstanding shares of capital stock of the Surviving Corporation. At the
Effective Time, the Shares will no longer be listed for quotation on the Nasdaq,
and the registration of the Shares under the Exchange Act will be terminated.
See "The Merger -- Certain Consequences of the Merger."

     Shares outstanding immediately prior to the Effective Time and held by a
holder who has not voted in favor of the Merger or consented thereto in writing
and who has delivered a written demand for appraisal of such Shares in
accordance with Section 262 of the DGCL will not be converted into the Merger
Consideration, unless and until such holder fails to perfect his right to
appraisal and payment under the DGCL, whereupon such Shares will be deemed to
have been converted as of the Effective Time into the right to receive the
Merger Consideration without any interest thereon, and such Shares will no
longer be Dissenting Shares. See "The Merger -- Appraisal Rights."

     Exchange of Certificates.  The Merger Agreement provides that prior to the
Effective Time, SBC shall appoint a depositary (the "Depositary") for the
purpose of exchanging certificates representing Shares for the Merger
Consideration. SBC will deposit with the Depositary immediately prior to the
Effective Time the Merger Consideration to be paid in respect of the Shares. For
purposes of determining the Merger

                                       26
<PAGE>   33

Consideration to be so paid, SBC will assume that no holder of Shares will
perfect his right to appraisal of his Shares. Promptly after the Effective Time,
SBC will send, or will cause the Depositary to send, but in no event later than
three business days after the Effective Time, to each holder of Shares at the
Effective Time, a letter of transmittal for use in such exchange (which shall
specify that the delivery shall be effected, and risk of loss and title shall
pass, only upon proper delivery of the certificates representing Shares to the
Depositary), as well as instructions for use in effecting the surrender of
Shares in exchange for the Merger Consideration. Each holder of Shares that have
been converted into a right to receive the Merger Consideration, upon surrender
to the Depositary of a certificate or certificates properly representing such
Shares, together with a properly completed letter of transmittal covering such
Shares, will be entitled to receive the Merger Consideration payable in respect
of such Shares. Until so surrendered, each such certificate shall, after the
Effective Time, represent for all purposes, only the right to receive such
Merger Consideration.

     If any portion of the Merger Consideration is to be paid to a Person (as
defined herein) other than the registered holder of the Shares represented by
the certificate or certificates surrendered in exchange therefor, it shall be a
condition to such payment that the certificate or certificates so surrendered
shall be properly endorsed or otherwise be in proper form for transfer, and that
the Person requesting such payment shall pay to the Depositary any transfer or
other taxes required as a result of such payment to a Person other than the
registered holder of such Shares or establish to the satisfaction of the
Depositary that such tax has been paid or is not payable. For purposes of the
Merger Agreement and this Proxy Statement, "Person" means an individual, a
corporation, a limited liability company, a partnership, an association, a trust
or any other entity or organization, including a government or political
subdivision or any agency or instrumentality thereof.

     After the Effective Time, there will be no further registration of
transfers of Shares. If, after the Effective Time, certificates representing
Shares are presented to the Surviving Corporation, they shall be canceled and
exchanged for the consideration provided for, and in accordance with the
procedures set forth, in the Merger Agreement. Any portion of the Merger
Consideration deposited with the Depositary that remains unclaimed by the
holders of Shares 180 days after the Effective Time shall be returned to the
Surviving Corporation, upon demand, and any such holder who has not exchanged
his Shares for the Merger Consideration in accordance with the Merger Agreement
prior to that time shall thereafter look only to the Surviving Corporation for
payment of the Merger Consideration in respect of such holder's Shares.
Notwithstanding the foregoing, SBC, Merger Subsidiary and the Surviving
Corporation shall not be liable to any holder of Shares for any amount paid to a
public official pursuant to applicable abandoned property laws. Any amounts
remaining unclaimed by holders of Shares on the day immediately prior to such
time as such amounts would otherwise escheat to or become property of any
governmental entity shall, to the extent permitted by applicable law, become the
property of SBC free and clear of any claim or interest of any Person previously
entitled thereto. Any portion of the Merger Consideration deposited with the
Depositary to pay for Shares for which Appraisal Rights have been perfected
shall be returned to the Surviving Corporation upon demand.

     STOCKHOLDERS OF THE COMPANY SHOULD NOT FORWARD THEIR SHARE CERTIFICATES TO
THE DEPOSITARY WITHOUT A LETTER OF TRANSMITTAL, AND SHOULD NOT RETURN THEIR
SHARE CERTIFICATES WITH THE ENCLOSED PROXY.

in total, or pursuant to which the Company or any of its subsidiaries incurs
obligations extending, either by the initial term thereof or by renewal, beyond

     Stockholder Approval.  Under the Merger Agreement, the Company has agreed
to take all action necessary in connection with applicable law to convene the
Special Meeting as soon as reasonably practicable after the date of the Merger
Agreement to consider and vote upon the Merger Agreement and the transactions
contemplated thereby. The Company has also agreed that the Board will recommend
adoption of the Merger Agreement by the Company's stockholders, provided that
the Board may withdraw, modify or change such recommendation if it determines,
after consultation with outside legal counsel to the Company, that such
recommendation would violate the fiduciary duties of the Directors under
applicable law. Notwithstanding

                                       29
<PAGE>   36

anything to the contrary contained in the Merger Agreement, the Company will
hold the Special Meeting for the purpose of allowing the Company's stockholders
to vote on the adoption of the Merger Agreement, including in the event that the
Board determines at any point subsequent to the date of the Merger Agreement
that the Merger Agreement is no longer advisable and recommends that the
stockholders of the Company reject it.

     Access to Information; Confidentiality.  The Company has agreed that, from
the date of the Merger Agreement until the Effective Time, it will give SBC and
SBC's counsel, financial advisors, auditors and other authorized representatives
reasonable access during normal business hours to the offices, properties, books
and records of the Company and the subsidiaries of the Company, will furnish to
SBC, its counsel, financial advisors, auditors and other authorized
representatives such financial and operating data and other information as such
Persons may reasonably request and will instruct the Company's employees,
counsel, accountants and financial advisors to cooperate with SBC in its
investigation of the business of the Company and the subsidiaries of the
Company; provided that all requests for information, to visit plants or
facilities or to interview the Company's employees or agents should be directed
to and coordinated with Mr. Stephen Shapiro or Mr. Richard Lubasch or, in their
absence, another person designated by the Company, and the Company will cause
Messrs. Lubasch and Shapiro and any such other person designated to cooperate
with SBC or its representatives in scheduling such visits or interviews. No
investigation of the business of the Company as described in the preceding
sentence shall affect any representation or warranty given by the Company to SBC
under the Merger Agreement and any information received by SBC or its
representatives will remain subject to the previously executed confidentiality
agreement between SBC and the Company with respect to information received from
the Company (the "Confidentiality Agreement").

     No Solicitation.  The Merger Agreement contains the following prohibition
on solicitations (the "No Solicitation Provision"):

          (i) The Company and its subsidiaries and their respective officers and
     directors will not, and the Company will use its best efforts to ensure
     that the respective officers, directors, employees or other agents
     (including any investment banker, attorney, consultant or accountant
     retained by it or its subsidiaries) of the Company and its subsidiaries
     will not, directly or indirectly, solicit, initiate, encourage or otherwise
     facilitate any Acquisition Proposal (as defined herein). The Company
     further agrees that it and its subsidiaries, officers and directors will
     not, and the officers and directors of its subsidiaries will not, and the
     Company will use its best efforts to ensure that the respective officers,
     directors and employees or other agents (including any investment banker,
     attorney, consultant or accountant retained by it or its subsidiaries) of
     the Company and its subsidiaries will not, directly or indirectly, engage
     in substantive discussions or negotiations with, disclose any nonpublic
     information relating to the Company or any subsidiary of the Company or
     afford access to the properties, books or records of the Company or any
     subsidiary of the Company or have any discussion with, any Person relating
     to an Acquisition Proposal; provided that, if prior to the date of the
     Special Meeting (A) such Person has on an unsolicited basis submitted a
     Superior Proposal (as defined herein), and (B) the Board determines, after
     consultation with outside legal counsel to the Company, that engaging in
     such negotiations or substantive discussions or providing such information
     is necessary for the Board to comply with its fiduciary duties under
     applicable law, the Company may in response to such Acquisition Proposal
     furnish information with respect to the Company and its subsidiaries
     pursuant to a confidentiality agreement no less onerous to the Person
     making the Acquisition Proposal than the Confidentiality Agreement and
     participate in negotiations and, subject to the terms of their agreement,
     enter into agreements regarding such Acquisition Proposal.

          (ii) The Company will notify SBC as promptly as practicable if any
     such inquiries, proposals or offers are received by, any such information
     is requested from, or any such discussions or negotiations are sought to be
     initiated or continued with any representative of the Company indicating
     the name of the Person contacting the Company and any material terms of any
     such proposals or offers and will keep SBC informed on a reasonably current
     basis of the status and details of any such Acquisition Proposal,
     indication or request.

                                       30
<PAGE>   37

          (iii) Nothing contained in the No Solicitation Provision will prohibit
     the Company or its Board from 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(a) promulgated under the
     Exchange Act or making such disclosure that the Board concludes in good
     faith after consultation with outside counsel is required by applicable
     Delaware law, taking into account any disclosures made pursuant to Rules
     14d-9 and 14e-2(a).

     For purposes of the Merger Agreement and this Proxy Statement, "Acquisition
Proposal" means any offer or proposal for a merger or other business combination
involving the Company or any subsidiary of the Company or the acquisition of any
equity interest in, or a substantial portion of the assets of, the Company or
any subsidiary of the Company, other than the transactions contemplated by the
Merger Agreement (an "Acquisition").

     For purposes of the Merger Agreement and this Proxy Statement, a "Superior
Proposal" means a bona fide written proposal to the Company relating to any such
transaction that provides for consideration which the Board determines in good
faith, after receiving advice from a nationally recognized investment banking
firm, is more favorable from a financial point of view to the Company and its
stockholders than the Merger Consideration; and the Board determines in good
faith (after consultation with a nationally recognized investment banking firm)
that such Acquisition Proposal, if accepted, is reasonably likely to be
consummated, taking into account all legal, financial and regulatory aspects of
the proposal and the financial capacity and any other relevant characteristics
of the Person making the Acquisition Proposal and which is not conditioned upon
obtaining financing.

     Conveyance Taxes.  The Company has agreed to timely pay any real property
transfer or gains, sales, use, transfer, value added, stock transfer and stamp
taxes, any transfer, recording, registration and other fees, and any similar
taxes (collectively, "Conveyance Taxes") which become payable prior to the
Effective Time and are required to be paid in connection with the transactions
contemplated by the Merger Agreement. Each of SBC and the Company has agreed to
cooperate in the preparation, execution and filing of all Tax Returns,
questionnaires, applications, or other documents regarding any Conveyance Taxes
which become payable in connection with the transactions contemplated by the
Merger Agreement that are required or permitted to be filed on or before the
Effective Time.

     For purposes of the Merger Agreement and this Proxy Statement, (i) "Taxes"
means all taxes, charges, fees, levies or other assessments, including, without
limitation, income, gross receipts, sales, use, ad valorem, goods and services,
capital, transfer, franchise, profits, license, withholding, payroll,
employment, employer health, excise, estimated, severance, stamp, occupation,
property or other taxes, customs duties, fees, assessments or charges of any
kind whatsoever, together with any interest and any penalties, additions to tax
or additional amounts imposed by any taxing authority; and (ii) "Tax Return"
means any report, return, documents, declaration or other information or filing
required to be supplied to any taxing authority or jurisdiction with respect to
Taxes.

     Takeover Statutes.  In the event any "fair price", "moratorium", "control
share acquisition" or other similar antitakeover statute or regulation shall
become applicable to any of the transactions contemplated by the Merger
Agreement, the Company has agreed that the Board will grant such approvals and
take such actions as are necessary so that such transactions may be consummated
as promptly as practicable on the terms contemplated thereby and otherwise act
to eliminate or minimize the effects of such statute or regulation on the
transactions contemplated thereby.

     Obligations of Merger Subsidiary.  SBC has agreed to take all actions
necessary to cause Merger Subsidiary to perform its obligations under the Merger
Agreement and to consummate the Merger on the terms and conditions set forth
therein.

     Indemnification and Insurance.  SBC has agreed that for a period of six
years after the Effective Time, SBC will, and will cause the Surviving
Corporation to, (A) indemnify and hold harmless the individuals who at or prior
to the Effective Time were officers, directors or employees of the Company (when
acting in such capacity) and any of its subsidiaries (the "Indemnitees") against
all losses, reasonable expenses, claims,

                                       31
<PAGE>   38

damages or liabilities incurred in connection with any claim, action, suit or
proceeding arising out of acts or omissions occurring at or prior to the
Effective Time (including, without limitation, in respect of acts or omissions
in connection with the Merger Agreement and the transactions contemplated
thereby) to the full extent permitted or required under applicable law and (B)
advance to such Indemnitees expenses (including attorneys' fees) incurred in
defending any action or suit with respect to such matters (including the cost of
any investigation and preparation incurred in connection thereof), in each case
to the fullest extent such Indemnitees are entitled to advancement of expenses
under and subject to the terms of the certificate of incorporation or bylaws of
the Company or the certificate of incorporation or bylaws of any subsidiary of
the Company (if the Indemnitee was acting in such Indemnitee's capacity as an
officer, director or employee); provided that in each case the Indemnitee to
whom expenses are advanced provides an undertaking to repay such advances if it
is ultimately determined that such Indemnitee is not entitled to
indemnification. To the extent permitted by the DGCL, such advancement of
expenses pursuant to the Merger Agreement will be mandatory rather than
permissive. In the event any claim or claims are asserted or made within such
six year period, all rights to indemnification in respect of any such claim or
claims will continue until disposition of any and all such claims. Any
determination required to be made with respect to whether any of the Indemnitees
are entitled to indemnification as set forth in the Merger Agreement will be
made by independent legal counsel selected mutually by such Indemnitee and SBC.

     Any Indemnitee wishing to claim indemnification under the provisions of the
Merger Agreement that are described in the preceding paragraph, upon learning of
any such claim, action, or suit must promptly notify SBC thereof, but the
failure to so notify will not relieve the Surviving Corporation of any liability
it may have to Indemnitee if such failure does not materially prejudice SBC or
the Surviving Corporation; provided that if the failure to so notify SBC
materially prejudices SBC or the Surviving Corporation, SBC or the Surviving
Corporation, as the case may be, will be relieved of liability it would
otherwise have had pursuant to the Merger Agreement to the extent of such
material prejudice. In the event of any such claim, action, suit or proceeding,
(i) SBC or the Surviving Corporation will have the right to assume the defense
thereof and SBC will not be liable to such Indemnitee for any legal expenses of
other counsel or any other expenses subsequently incurred by such indemnitee in
connection with the defense thereof, (ii) the Indemnitee will cooperate in the
defense of any such matter and (iii) SBC will not be liable for any settlement
effected without its prior written consent; and provided further that SBC will
not have any obligation hereunder to any Indemnitee if and when a court of
competent jurisdiction ultimately determines, and such determination becomes
final, that the indemnification of such Indemnitee in the manner contemplated is
prohibited by applicable law.

     Under the Merger Agreement, SBC, Merger Subsidiary and the Company have
agreed that all rights to indemnification and all limitations on liability
existing in favor of any such Indemnitee as provided in the certificate of
incorporation or bylaws of the Company or an agreement between an Indemnitee and
the Company or a subsidiary of the Company as in effect as of the date hereof
will survive the Merger and continue in full force and effect. SBC has also
agreed that for a period of six years after the Effective Time, SBC will, and
will cause the Surviving Corporation to, provide D&O Insurance in respect of
acts or omissions occurring prior to the Effective Time covering each such
Person currently covered by the Company's D&O Insurance policy on terms with
respect to coverage and amount no less favorable than those of such policy in
effect on the date hereof so long as the annual premium therefor does not exceed
150% of the annual premium payable pursuant to the renewal policy disclosed to
SBC (the "Current Premiums"); provided, however, that if the existing D&O
Insurance expires, is terminated or canceled during such six-year period, the
Surviving Corporation will use its reasonable best efforts to obtain as much D&O
Insurance as can be obtained for the remainder of such period for a premium not
in excess (on an annualized basis) of 150% of the Current Premium. SBC has
further agreed that, should the Surviving Corporation fail to comply with the
obligations under the Merger Agreement that are described herein, SBC shall be
responsible therefor to the extent permitted by Delaware law.

     The Merger Agreement provides that in the event the Company or the
Surviving Corporation or any of their respective successors or assigns (i)
consolidates with or merges into any other person or entity or (ii) transfers
all or substantially all of its properties or assets to any Person, then, and in
each case, proper

                                       32
<PAGE>   39

provision shall be made so that successors and assigns of the Company or the
Surviving Corporation, as the case may be, honor the indemnification obligations
set forth in the Merger Agreement.

     The obligations of the Company, the Surviving Corporation, and SBC under
the terms of the Merger Agreement relating to director and officer liability may
not be terminated or modified in such a manner as to adversely affect any
Indemnitee to whom such terms apply, without the consent of such affected
Indemnitee (it being expressly agreed that the Indemnitees to whom such terms
apply shall be third party beneficiaries of such terms).

     Reasonable Efforts.  The Merger Agreement provides that, subject to the
terms and conditions thereof, each party will 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 under applicable laws and regulations to
consummate the transactions contemplated thereby.

     Certain Filings, Consents and Arrangements.  Each of the Company and SBC
has agreed to use its commercially reasonable efforts, (i) within 30 days after
the date of the Merger Agreement or as soon as practicable thereafter, to (A)
file or cause to be filed, and share equally the fee for, the notification and
report forms required under the HSR Act and make promptly any required
submissions under the HSR Act with respect to the transactions contemplated by
the Merger Agreement, (B) to the extent required by applicable laws, file with
the FCC applications for consent to transfer of control of the licenses, as
applicable, and such other applications as may be advisable in the reasonable
judgment of the parties hereto, which applications will comply in all material
respects with the requirements of the Communications Act and (C) file
applications for all consents and approvals of any State Governmental Body and
other regulatory consents and approvals necessary for the consummation of the
transactions contemplated by the Merger Agreement, and (ii) to cooperate with
one another (A) in promptly determining whether any filings are reasonably
required to be or should be made or consents, approvals, permits or
authorizations are required to be or should be obtained under any other federal,
state or local law or regulation and (B) in promptly making any such filings,
furnishing information required in connection therewith and using commercially
reasonable efforts to seek to obtain timely any such consents, permits,
authorizations, approvals or waivers.

     Public Announcements.  SBC and the Company have agreed to consult with each
other before issuing any press release or making any public statement with
respect to the Merger Agreement and the transactions contemplated thereby and,
except (i) as may be required by applicable law or any listing agreement with
any national securities exchange or foreign securities exchange or (ii) for any
communication by the Company to its employees describing the terms of the Merger
Agreement, will not issue any such press release or make any such public
statement prior to such consultation. To the extent that the provisions of the
Merger Agreement relating to public announcements as described in the preceding
sentence conflict with the terms of the Confidentiality Agreement, the
provisions of the Merger Agreement will prevail.

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

     Employee Matters.  The Merger Agreement contains the following covenants
relating to certain employee matters:

          (i) For a period of one year immediately following the Closing Time,
     SBC agrees to cause the Surviving Corporation and its subsidiaries to
     provide to all active employees of the Company who continue to be employed
     by the Company as of the Effective Time ("Continuing Employees") coverage
     by benefit plans or arrangements which are, in the aggregate, no less
     favorable in the aggregate than those provided to the employees immediately
     prior to the Closing Time with the exception of any stock option, stock

          (ii) For a period of one year immediately following the Closing Time,
     SBC agrees to cause the Surviving Corporation and its subsidiaries to
     provide to all active employees of the Company at the Closing Time which
     may be affected by any reduction in force subsequent to the Closing Time
     benefits no less favorable in the aggregate than the benefits set forth in
     the severance policy adopted by the Board for all Puerto Rico resident
     employees of the Company.

          (iii) The Company agrees to mail, promptly after the execution of the
     Merger Agreement, to each person who is a holder of Option granted pursuant

     vested or exercisable at the time) a letter in a form acceptable to SBC
     which describes the treatment of and payment for such Options and provides
     instructions for use in obtaining payment for such Options. Each such
     holder shall be requested to sign a release by which the holder effectively
     relinquishes all rights with respect to all Options issued pursuant to any
     of the stock option plans upon payment therefor in connection with the
     Closing.

TERMINATION; CERTAIN FEES

     The Merger Agreement may be terminated and the Merger may be abandoned at
any time prior to the Effective Time, whether before or after the approval by
stockholders of the Company, by mutual written consent of the Company and SBC or
by action of their respective Boards of Directors. The Merger Agreement may also
be terminated and the Merger may be abandoned at any time prior to the Effective
Time by action of the Board of Directors of either SBC or the Company if (i) the
Merger shall not have been consummated by February 1, 2000, whether such date is
before or after the date of approval by the stockholders of the Company;
provided, however, that if either party determines that additional time is
necessary in order to forestall any action to restrain, enjoin or prohibit the
Merger by any governmental entity, the termination date may be extended by such
party to a date not beyond May 1, 2000; (ii) the approval of the Company's
stockholders shall not have been obtained at a meeting duly convened therefor or
at any adjournment or postponement thereof; or (iii) any Order permanently
restraining, enjoining or otherwise prohibiting consummation of the Merger shall
be a Final Order; provided, that the right to terminate the Merger Agreement
pursuant to clause (i) above shall not be available to any party that has
breached in any material respect its obligations under the Merger Agreement in
any manner that shall have proximately contributed to the occurrence of the
failure of the Merger to be consummated.

     The Merger Agreement may be terminated and the Merger may be abandoned at
any time prior to the approval by stockholders of the Company or by action of
the Board if (i) the Company is not in material breach of any of the terms of
the Merger Agreement; (ii) the Board authorizes the Company, subject to
complying with the terms of the Merger Agreement, to enter into a binding
written agreement concerning a transaction that constitutes a Superior Proposal
and the Company notifies SBC in writing that it intends to enter into such an
agreement, attaching the most current version of such agreement to such notice;
(iii) SBC does not make, within five business days after receipt of the
Company's written notification of its intention to enter into a binding
agreement for a Superior Proposal, an offer that the Board determines, in good
faith after consultation with an investment banker of national reputation, is at
least as favorable, from a financial point of view, to the stockholders of the
Company as the Superior Proposal; and (iv) the Company prior to such termination
pays to SBC in immediately available funds any fees required to be paid pursuant
to the Merger Agreement. Termination of the Merger Agreement is further
conditioned by the Company's agreement

                                       35
<PAGE>   42

(x) that it will not enter into a binding agreement referred to in clause (iii)
above until at least the sixth business day after it has provided the required
notice to SBC and (y) that it will notify SBC promptly if its intention to enter
into a written agreement referred to in its notification shall change at any
time after giving such notification. Additionally, the Merger Agreement may be
terminated if there has been a material breach by SBC or Merger Subsidiary of
any representation, warranty, covenant or agreement contained in the Merger
Agreement that is not curable or, if curable, is not cured within 30 days after
written notice of such breach is given by the Company to the party committing
such breach.

     The Merger Agreement may be terminated and the Merger may be abandoned at
any time prior to the Effective Time by action of the Board of Directors of SBC
if: (i) the Board shall have withdrawn or adversely modified its approval or
recommendation of the Merger Agreement; (ii) there has been a material breach by
the Company of any representation, warranty, covenant or agreement contained in
the Merger Agreement that is not curable or, if curable, is not cured within 30
days after written notice of such breach is given by SBC to the party committing
such breach; or (iii) if the Company or any of the other Persons, including the
officers, directors, employees or other agents of the Company and its
Subsidiaries wilfully and materially breach the No Solicitation Provision of the
Merger Agreement.

     In the event of termination of the Merger Agreement and the abandonment of
the Merger, the covenants of the Merger Agreement, unless concerning SBC's
director's and officer's liability, the Company's employee matters and the terms
of termination and abandonment of the Merger Agreement and the Merger, shall
become void and of no effect with no liability on the part of any party hereto
(or of any of its directors, officers, employees, agents, legal and financial
advisors or other representatives); provided, however, no such termination shall
relieve any party hereto of any liability or damages resulting from any breach
of the Merger Agreement.

     In the event that (i) an Acquisition Proposal shall have been made to the
Company or any of its Subsidiaries or any of its stockholders or any Person
shall have publicly announced an intention (whether or not conditional) to make
an Acquisition Proposal with respect to the Company or any of its subsidiaries
and thereafter the Merger Agreement is terminated by either SBC or the Company
pursuant to the Merger Agreement; or (ii) the Merger Agreement is terminated by
the Company or SBC pursuant to the Merger Agreement, then the Company shall
promptly, but in no event later than two days after the date of such termination
(or in the case of termination pursuant to a bona fide and properly disclosed
Superior Proposal, immediately prior to the termination thereof by the Company),
pay SBC a termination fee of $20 million (the "Termination Fee"). In the event
that this Agreement is terminated pursuant to the Company's breaching the
restrictions on the solicitation of Superior Proposals and either (x) within six
months thereafter the Company enters into an agreement providing for an
Acquisition or (y) within two years thereafter the Company enters into an
agreement providing for an Acquisition with a Person with whom the Company had
substantive discussions or negotiated or to whom the Company disclosed, or
afforded access, to any nonpublic information prior to the termination of the
Merger Agreement pursuant to the "No Solicitation" provision of the Merger
Agreement, then the Company shall pay SBC the Termination Fee within two
business days after the entry into such agreement. If SBC commences an action to
obtain payment of the Termination Fee, the prevailing party in such action shall
be reimbursed for its reasonable costs and expenses (including reasonable
attorney's fees) in prosecuting or defending such action. If SBC shall prevail
in such action, the Company shall pay interest on the Termination Fee (at the
prime rate of Citibank N.A. in effect on the date such payment was required to
be made) from the date such payment was required to be made to the date made.

                                 THE COMPANIES

THE COMPANY

     The Company, through wholly and majority owned entities, owns, operates and
markets cellular and paging systems in the Commonwealth of Puerto Rico and the
U.S. Virgin Islands and conducts certain other telecommunications related
operations. As of March 31, 1999, the Company had an aggregate of approximately
332,600 cellular telephone subscribers which represents a penetration rate
(i.e., the number of subscribers divided by the total estimated population of
the Company's markets) for the Company of approximately 8.6%. In addition, as of
March 31, 1999, the Company's paging operations had approximately 58,800 pagers
in use.

     The Company is a Delaware corporation that was incorporated on January 13,
1997. From January 31, 1997 to September 2, 1998 (the "Spin-off Date"), the
Company was known as CoreComm Incorporated. On the Spin-off Date, the Company
changed its name from CoreComm Incorporated to Cellular Communications of Puerto
Rico, Inc. and distributed to its stockholders on a one-for-one basis all of the
shares of its wholly owned subsidiary, CoreComm Limited. Prior to January 31,
1997 (the "Merger Date"), a predecessor of the Company was known as Cellular
Communications of Puerto Rico, Inc. ("Old CCPR"). From its date of incorporation
until the Merger Date, the Company was a wholly owned subsidiary of Old CCPR. On
the Merger Date, Old CCPR effected a corporate restructuring (the
"Restructuring") whereby stockholders of Old CCPR became stockholders of the
Company on a one-for-one basis upon the completion of a merger of Old CCPR with
and into a subsidiary of the Company. As a result of the Restructuring, the
Company replaced Old CCPR as the publicly traded entity and Old CCPR became a
wholly owned subsidiary of the Company.

                CERTAIN PROJECTIONS OF FUTURE OPERATING RESULTS

     The Company does not as a matter of course make public forecasts as to its
future financial performance and conditions. However, in connection with its
discussions with SBC and other potential acquirors of the Company, the Company
furnished SBC and such other potential acquirors certain data relating to
projected future operating results and financial conditions of the Company. The
projections set forth below were included in the data provided by the Company to
such interested parties, including SBC. These projections were not prepared in
compliance with the published guidelines of the American Institute of Certified
Public Accountants or the SEC regarding projections or financial forecasts and
are included herein only because such information was provided to SBC. These
projections constitute forward-looking statements and were based upon numerous
assumptions, the more material of which are summarized below. Although the
Company believes that such assumptions were reasonable when made, such
assumptions are inherently subject to significant uncertainties and
contingencies which are difficult or impossible to predict and are beyond the
Company's control. Accordingly, there can be no assurance, and no representation
or warranty is made, that

                                       38
<PAGE>   45

the actual results of operations and financial position achieved by the Company
would not vary materially from the results of operations and financial condition
set forth in these projections. For a list of important factors that, in the
view of the Company, could cause actual results to differ materially from those
set forth in these projections, see "Forward-Looking Statements." The
projections set forth below have not been adjusted to reflect the effects of the
Merger:

</TABLE>

     The following represent the most significant assumptions made in the
determination of the financial projections presented above.

     (a) Estimated population of Puerto Rico of 3.9 million as of January 1999
         and annual population growth rate of 0.5%;

     (b) Market penetration rate growth from 14.7% at year end 1998 to 31% in
         2001, based on several factors including increased consumer awareness
         and acceptance, prepaid services, digital technology, lower telephone
         prices and improved functionality, increased PCS competition and the
         introduction of Calling Party Pays in 2000;

     (c) Decrease in churn rate due to improved customer retention programs,
         prepaid service and the introduction of Calling Party Pays.

     (d) Gradual decrease in projected average revenue per subscriber through
         2000 due to the rapidly growing base of lower average revenue prepaid
         customers.

     The wireless revenue and EBITDA projections do not include any potential
revenue or cash flow effect of a potential rollout of wireline fiber-based
competitive local exchange carrier services by the Company.

     The projections set forth above were prepared by the Company in January
1999 in connection with the Company's annual profit planning process and the
private auction process to sell the Company. Forecasts of future financial
performance and condition could differ materially from the data set forth above
if management were to prepare projections based upon circumstances existing as
of the date of this Proxy Statement. None of the Company or SBC intends or has
any duty or obligation publicly to disclose updates or revisions to any of the
projections set forth above to reflect the occurrence of unanticipated events.
The Company's independent accountants have not examined or compiled the
foregoing forward-looking statements and accordingly do not provide any
assurance with respect to such statements.

                          AGREEMENT AND PLAN OF MERGER

     AGREEMENT AND PLAN OF MERGER, dated as of April 30, 1999 (this
"Agreement"), by and among Cellular Communications of Puerto Rico, Inc., a
Delaware corporation (the "Company"), SBC Communications Inc., a Delaware
corporation ("Buyer"), and SBC International-PR, Inc., a Delaware corporation
and an indirect wholly owned subsidiary of Buyer ("Merger Subsidiary").

     WHEREAS, the respective Boards of Directors of Buyer, Merger Subsidiary and
the Company have determined that it is fair to, advisable and in the best
interests of their respective stockholders to consummate the acquisition of the
Company by Buyer upon the terms and subject to the conditions set forth herein;
and

     WHEREAS, in furtherance of such acquisition, the respective Boards of
Directors of Buyer, Merger Subsidiary and the Company have approved the merger
of Merger Subsidiary with and into the Company in accordance with the Delaware
General Corporation Law (the "DGCL") whereby each issued and outstanding share
("Shares") of the issued and outstanding common stock, par value $.01 per share,
of the Company (other than Shares owned by the Company or any Subsidiary (as
defined below) or owned by Buyer, Merger Subsidiary or any other subsidiary of
Buyer immediately prior to the Effective Time and other than Dissenting Shares
(as defined in Section 1.4 hereof) collectively, "Excluded Shares"), including
the associated preferred stock purchase rights (the "Rights") issued pursuant to
the rights agreement, dated as of January 24, 1992 between the Company and
Continental Stock Transfer & Trust Company (the "Rights Agreement"), will be
converted into the right to receive $29.50 per Share in cash, without interest
(the "Merger Consideration");

     WHEREAS, Buyer, Merger Subsidiary and the Company desire to make certain
representations, warranties, covenants and agreements in connection with the
Merger and also to prescribe various conditions to the Merger (as defined
herein).

     NOW, THEREFORE, in consideration of the representations, warranties,
covenants and agreements contained in this Agreement, the parties hereto agree
as follows:

                                   ARTICLE I

                                   THE MERGER

     SECTION 1.1  The Merger.  (a) Subject to the terms and conditions of this
Agreement, and in accordance with the DGCL, at the Effective Time, Merger
Subsidiary shall be merged (the "Merger") with and into the Company, whereupon
the separate existence of Merger Subsidiary shall cease, and the Company shall
be the surviving corporation (the "Surviving Corporation") and shall continue to
be governed by the laws of the State of Delaware.

     (b) The Company, Buyer and Merger Subsidiary will cause a certificate of
merger (the "Certificate of Merger") with respect to the Merger to be executed
and filed with the Secretary of State of the State of Delaware (the "Secretary
of State") as provided in the DGCL. The Merger shall become effective on the
date and time the Certificate of Merger has been duly filed with the Secretary
of State or at such other date and time as is agreed between the parties and is
specified in the Certificate of Merger, and such time is hereinafter referred to
as the "Effective Time."

     (c) From and after the Effective Time, the Surviving Corporation shall
possess all the rights, privileges, immunities, powers and franchises and be
subject to all of the restrictions, disabilities, liabilities and duties of the
Company and Merger Subsidiary.

     SECTION 1.2  Effect on Shares.  At the Effective Time:

     (a) Cancellation of Certain Stock.  Each of the Excluded Shares outstanding
immediately prior to the Effective Time shall, by virtue of the Merger and
without any action on the part of the holder thereof, automatically be canceled
and retired and cease to exist, and, subject to Section 1.4 hereof and Section
262 of the DGCL, no payment shall be made with respect thereto.

                                       A-5
<PAGE>   53

     (b) Capital Stock of Merger Subsidiary.  Each share of common stock, par
value $1.00 per share, of Merger Subsidiary issued and outstanding immediately
prior to the Effective Time shall be converted into and become one share of
common stock, par value $.01 per share, of the Surviving Corporation with the
same rights, powers and privileges as the shares so converted and shall
constitute the only outstanding shares of capital stock of the Surviving
Corporation.

     (c) Conversion of Shares.  Each Share issued and outstanding immediately
prior to the Effective Time shall, except as otherwise provided in Section
1.2(a) hereof, be converted into the right to receive the Merger Consideration.
Notwithstanding the foregoing, if between the date of this Agreement and the
Effective Time the outstanding Shares shall have been changed into a different
number of shares or a different class, by reason of any stock dividend or
distribution, subdivision, reclassification, recapitalization, stock split
(including a reverse split), merger combination, issuer tender or exchange other
or other similar transaction, the Merger Consideration shall be correspondingly
adjusted on a per-share basis to reflect such change.

     SECTION 1.3  Surrender and Payment.  (a) Prior to the Effective Time, Buyer
shall appoint a depositary (the "Depositary") for the purpose of exchanging
certificates representing Shares for the Merger Consideration. The Depositary
shall at all times be a commercial bank having a combined capital and surplus of
at least $100,000,000. Buyer shall deposit with the Depositary immediately prior
to the Effective Time, the Merger Consideration to be paid in respect of the
Shares. For purposes of determining the Merger Consideration to be so paid,
Buyer shall assume that no holder of Shares will perfect his right to appraisal
of his Shares. Promptly after the Effective Time, Buyer will send, or will cause
the Depositary to send, but in no event later than three Business Days after the
Effective Time, to each holder of Shares at the Effective Time a letter of
transmittal for use in such exchange (which shall specify that the delivery
shall be effected, and risk of loss and title shall pass, only upon proper
delivery of the certificates representing Shares to the Depositary) and
instructions for use in effecting the surrender of Shares in exchange for the
Merger Consideration.

     (b) Each holder of Shares that have been converted into a right to receive
the Merger Consideration, upon surrender to the Depositary of a certificate or
certificates properly representing such Shares, together with a properly
completed letter of transmittal covering such Shares, will be entitled to
receive the Merger Consideration payable in respect of such Shares. Until so
surrendered, each such certificate shall, after the Effective Time, represent
for all purposes, only the right to receive such Merger Consideration.

     (c) If any portion of the Merger Consideration is to be paid to a Person
other than the registered holder of the Shares represented by the certificate or
certificates surrendered in exchange therefor, it shall be a condition to such
payment that the certificate or certificates so surrendered shall be properly
endorsed or otherwise be in proper form for transfer and that the Person
requesting such payment shall pay to the Depositary any transfer or other taxes
required as a result of such payment to a Person other than the registered
holder of such Shares or establish to the satisfaction of the Depositary that
such tax has been paid or is not payable. For purposes of this Agreement,
"Person" means an individual, a corporation, a limited liability company, a
partnership, an association, a trust or any other entity or organization,
including a government or political subdivision or any agency or instrumentality
thereof.

     (d) After the Effective Time, there shall be no further registration of
transfers of Shares. If, after the Effective Time, certificates representing
Shares are presented to the Surviving Corporation, they shall be canceled and
exchanged for the consideration provided for, and in accordance with the
procedures set forth, in this Article I.

     (e) Any portion of the Merger Consideration deposited with the Depositary
pursuant to Section 1.3(a) that remains unclaimed by the holders of Shares 180
days after the Effective Time shall be returned to Surviving Corporation, upon
demand, and any such holder who has not exchanged his Shares for the Merger
Consideration in accordance with this Section 1.3 prior to that time shall
thereafter look only to the Surviving Corporation for payment of the Merger
Consideration in respect of such holder's Shares. Notwithstanding the foregoing,
Buyer, Merger Subsidiary and the Surviving Corporation shall not be liable to
any holder of Shares for any amount paid to a public official pursuant to
applicable abandoned property laws. Any amounts remaining unclaimed by holders
of Shares on the day immediately prior to such time as such amounts would
otherwise escheat to or become property of any governmental entity shall, to the
extent permitted by

interest of any Person previously entitled thereto.

     (f) Any portion of the Merger Consideration deposited with the Depositary
pursuant to Section 1.3(a) hereof to pay for Shares for which appraisal rights
have been perfected shall be returned to Surviving Corporation upon demand.

     SECTION 1.4  Dissenting Shares.  Notwithstanding Section 1.2 hereof, Shares
issued and outstanding immediately prior to the Effective Time and held by a
holder who has properly exercised and perfected appraisal rights under Section
262 of the DGCL (the "Dissenting Shares"), shall not be converted into the right
to receive the Merger Consideration, but the holders of Dissenting Shares shall
be entitled to receive such consideration as shall be determined pursuant to
Section 262 of the DGCL; provided, however, that if any such holder shall have
failed to perfect or shall withdraw or lose his right to appraisal and payment
under the DGCL, subject to Section 262 of the DGCL, such holder's Shares shall
thereupon be deemed to have been converted as of the Effective Time into the
right to receive the Merger Consideration, without any interest thereon, and
such Shares shall no longer be Dissenting Shares. The Company shall (i) give
Buyer prompt notice of any written demands for appraisal, attempted withdrawals
of such demands and any other instruments or documents received by the Company
relating to stockholders' appraisal rights and (ii) allow Buyer to direct all
negotiations and proceedings with respect to demands for appraisal under Section
262 of the DGCL.

     SECTION 1.5  Stock Options.  Immediately prior to the Effective Time, each
outstanding employee or director stock option (an "Option") to purchase Shares
granted under any employee or director stock option or compensation plan or
arrangement of the Company shall be canceled, and each holder of any such
Option, whether or not then vested or exercisable, shall be paid by the Company
as soon as practicable after the Effective Time for each such Option an amount
determined by multiplying (i) the excess, if any, of the Merger Consideration
over the applicable exercise price of such Option by (ii) the number of Shares
such holder could have purchased (assuming full vesting of all Options) had such
holder exercised such Option in full immediately prior to the Effective Time,
subject in case of payment to any such holder's signing a release as is
contemplated by the provisions of Section 7.6(c). The Company shall take all
such steps as may be required to cause the transactions contemplated by this
Section 1.5 and any other dispositions of Company equity securities (including
derivative securities) in connection with this Agreement or the transactions
contemplated hereby by each individual who is a director or officer of the
Company, to be exempt under Rule 16b-3 promulgated under the Securities Exchange
Act of 1934, as amended (the "Exchange Act"), such steps to be taken in
accordance with the interpretive letter dated January 12, 1999, issued by the
Securities and Exchange Commission to Skadden, Arps, Slate, Meagher & Flom LLP.

     SECTION 1.6  Closing.  The closing of the Merger (the "Closing") will take
place at 10:00 a.m., New York City time, on a date to be specified by the
parties hereto, which shall be no later than the third Business Day after
satisfaction or waiver of all of the conditions set forth in Article VIII hereof
(other than those conditions that by their nature are to be satisfied at the

                                  ARTICLE III

                         REPRESENTATIONS AND WARRANTIES
                                 OF THE COMPANY

     The Company represents and warrants to Buyer and Merger Subsidiary that:

     SECTION 3.1  Corporate Existence and Power.  Each of the Company and its
subsidiaries is a corporation duly incorporated, validly existing and in good
standing under the laws of the State of Delaware, and except as set forth on
Schedule 3.1 of the disclosure schedule of the Company (the "Company Disclosure
Schedule"), has all corporate powers and all governmental licenses,
authorizations, consents and approvals (collectively, "Licenses") required to
carry on its business as now conducted except where the failure to have any such
License has not had and would not be reasonably likely to have, individually or
in the aggregate, a Material Adverse Effect (as defined below) provided, that
the Company and its Subsidiaries have all Communications Licenses, whether or
not the failure to have any such License would have a Material Adverse Effect.
The Company is duly qualified to do business as a foreign corporation and is in
good standing in each jurisdiction where the character of the property owned or
leased by it or the nature of its activities makes such qualification necessary,
except for those jurisdictions where the failure to be so qualified would not be
reasonably likely, individually or in the aggregate, to have a Material Adverse
Effect. As used herein, the term "Material Adverse Effect" means a material
adverse effect on the condition (financial or otherwise), business, properties,
assets, liabilities, or results of operations of the Company and its
Subsidiaries (as defined in Section 3.6), taken as a whole, that is not a result
of adverse changes of general applicability in the economy or the industries in
which such entities operate or regulatory changes applicable to the cellular
telephone industry generally. The Company has heretofore delivered or made
available to Buyer true and complete copies of the Company Certificate of
Incorporation and Company By-laws as currently in effect.

     SECTION 3.2  Corporate Authorization.  The execution, delivery and
performance by the Company of this Agreement and the consummation by the Company
of the transactions contemplated hereby are within the Company's corporate
powers and, except for approval by the Company's stockholders in connection with
the consummation of the Merger, have been duly authorized by all necessary
corporate action. This Agreement, assuming due and valid authorization,
execution and delivery by Buyer and Merger Sub, constitutes a valid and binding
agreement of the Company enforceable against the Company in accordance with its
terms, except that (i) enforcement may be subject to applicable bankruptcy,
insolvency, reorganization, moratorium or other similar laws, now or hereafter
in effect, affecting creditors' rights generally, and (ii) the remedy of
specific performance and injunctive and other forms of equitable relief may be
subject to equitable defenses of general applicability.

<PAGE>   56

     SECTION 3.3  Governmental Authorization.  (a) Except as set forth in
Schedule 3.3(a)(i) of the Company Disclosure Schedule, the execution, delivery
and performance by the Company of this Agreement and the consummation by the
Company of the transactions contemplated hereby do not require any action by or
in respect of, or filing with, any governmental or regulatory body, agency,
court, commission, official, authority or other governmental entity (each, a
"Governmental Entity") other than: (i) the filing of a certificate of merger in
accordance with the DGCL; (ii) compliance with any applicable requirements of
the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the "HSR Act"); (iii)
compliance with any applicable requirements of the Securities Exchange Act of
1934, as amended (the "Exchange Act"); (iv) compliance with the applicable
requirements of state blue sky laws; (v) consent by the Federal Communications
Commission (the "FCC") to the transfer of control of any Licenses subject to the
jurisdiction of the FCC; and (vi) compliance with any applicable requirements
imposed by the other state public utilities commissions or similar regulatory
bodies set forth on Schedule 3.3(a)(ii), which contains a complete list of all
such commissions and other regulatory bodies.

     (b) Each of the Licenses is in full force and effect and has not been
assigned, suspended, modified in any respect, cancelled, or revoked, and there
is no contract, agreement or understanding to assign, suspend, modify in any
respect, cancel or revoke any of the Licenses. The Company has operated in
compliance with the terms of the Licenses and any renewals thereof applicable to
it except, in the case of non-material Licenses, where failure to so comply has
not had and is not reasonably likely to have, individually or in the aggregate,
a Material Adverse Effect provided that the Company has operated in compliance
with all material terms of the Communications Licenses, whether or not the
failure to so comply has had or is reasonably likely to have, individually or in
the aggregate, a Material Adverse Effect. No event has occurred with respect to
any of the Licenses which permits, or after notice or lapse of time or both
would permit, revocation or termination thereof or would result in any other
impairment of the rights of the holder of any such Licenses. There is not
pending or threatened any application, petition, objection, or other pleading
with the FCC, any state, commonwealth or territorial governmental body with
jurisdiction over the Company ("State Governmental Body") or any similar body
having jurisdiction or authority over the Company which questions the validity
of or contests any License or which presents a substantial risk that, if
accepted or granted, it would result in the revocation, cancellation, failure to
renew, or suspension, or any modification, of any License.

     (c) Schedule 3.3(c) of the Company Disclosure Schedule sets forth a true,
accurate and complete list of the Communications Licenses held by the Company or
its Subsidiaries, and the identity of each Person that holds each such
Communications License. "Communications Licenses" shall mean all Licenses
including, without limitation, Licenses from the FCC, certificates of
convenience and necessity, certificates of authority and other similar
certificates, necessary to carry on the business of the Company and its
Subsidiaries under applicable requirements of the FCC or State Governmental
Bodies substantially in the manner such business is currently conducted by the
Company.

     SECTION 3.4  Non-Contravention.  The execution, delivery and performance by
the Company of this Agreement and the consummation by the Company of the
transactions contemplated hereby do not and will not (i) contravene or conflict
with the Company Certificate of Incorporation or Company By-laws, (ii) except as
set forth in Schedule 3.4 of the Company Disclosure Schedule and assuming
compliance with the matters referred to in Section 3.3 hereof, contravene or
conflict with or constitute a violation of any provision of any law, regulation,
judgment, injunction, order or decree binding upon or applicable to the Company
or any Subsidiary of the Company, (iii) except as set forth in Schedule 3.4 of
the Company Disclosure Schedule, with or without the giving of notice or passage
of time or both, constitute a default under or give rise to a right of
termination, cancellation or acceleration of any right or obligation of the
Company or any Subsidiary of the Company or to a loss of any benefit to which
the Company or any Subsidiary of the Company is entitled under any provision of
any agreement, contract or other instrument binding upon the Company or any
Subsidiary of the Company or any license, franchise, permit or other similar
authorization held by the Company or any Subsidiary of the Company, or (iv)
result in the creation or imposition of any Lien (as defined below) on any asset
of the Company or any Subsidiary of the Company, excluding from the foregoing
clause (iii) such violations, breaches, defaults or Liens which would not
reasonably be likely, individually or in the aggregate, to

                                       A-9
<PAGE>   57

have a Material Adverse Effect. For purposes of this Agreement, "Lien" means,
with respect to any asset, any mortgage, lien, pledge, charge, security interest
or encumbrance of any kind in respect of such asset.

     SECTION 3.5  Capitalization.  The authorized capital stock of the Company
consists of 30,000,000 Shares and 2,500,000 shares of preferred stock, par value
$.01 per share, of the Company (the "Preferred Stock"). As of April 27, 1999,
there were not more than (i) 13,438,770 Shares issued and outstanding; and (ii)
383,000 Shares held in the Company's treasury and no other Shares were issued or

Schedule 3.5 of the Company Disclosure Schedule contains a correct and complete
list of each outstanding option to purchase Shares ("Options"), including the

of capital stock of the Company have been duly authorized and validly issued and
are fully paid and nonassessable. Except as set forth in this Section 3.5, and

Options granted to employees outstanding on such date, there are no outstanding
shares of capital stock or other voting securities of the Company, (ii) there
are no outstanding securities of the Company or of any Subsidiary of the Company
convertible into or exchangeable for shares of capital stock or voting
securities of the Company or any Subsidiary, and (iii) except as set forth on
Schedule 3.5 of the Company Disclosure Schedule, there are no preemptive rights,
warrants, options or other rights to acquire from the Company, and no obligation
of the Company to issue, any capital stock, voting securities or securities
convertible into or exchangeable for capital stock or voting securities of the
Company (the items in clauses (i), (ii) and (iii) being referred to collectively
as the "Company Securities"). There are no outstanding obligations of the
Company or any Subsidiary of the Company to repurchase, redeem or otherwise
acquire any Company Securities.

     SECTION 3.6  Subsidiaries.  (a) Each Subsidiary of the Company that is
actively engaged in any business or owns any assets (an "Active Subsidiary") (i)
is a corporation duly incorporated, validly existing and in good standing under
the laws of its jurisdiction of incorporation, (ii) except as set forth in
Schedule 3.6(a)(i) of the Company Disclosure Schedule, has all corporate powers
and all material governmental licenses, authorizations, consents and approvals
required to carry on its business as now conducted and (iii) is duly qualified
to do business as a foreign corporation and is in good standing in each
jurisdiction where the character of the property owned or leased by it or the
nature of its activities makes such qualification necessary. For purposes of
this Agreement, "Subsidiary" means with respect to any Person, any corporation
or other legal entity of which such Person owns, directly or indirectly, more
than 50% of the outstanding stock or other equity interests, the holders of
which are entitled to vote for the election of the board of directors or other
governing body of such corporation or other legal entity or otherwise has the
right to cause the election of a majority of the board of directors or other
governing body of such corporation or other legal entity. All Active

jurisdictions of incorporation are identified on Schedule 3.6(a)(ii) of the
Company Disclosure Schedule.

     (b) Except as set forth on Schedule 3.6(b) of the Company Disclosure
Schedule, each outstanding share of capital stock of each Subsidiary of the
Company has been duly and validly authorized and issued, is fully paid and
nonassessable and is owned by the Company and/or one or more of its Subsidiaries

(including any restriction on the right to vote, sell or otherwise dispose of
such capital stock). There are no subscriptions, options, warrants, calls,
rights, convertible securities or other agreements or commitments of any

interests of any of such Subsidiaries. There are no agreements requiring the
Company or any of its Subsidiaries to make contributions to the capital of, or
lend or advance funds to, any Subsidiaries of the Company.

     (c) Schedule 3.6(c) of the Company Disclosure Schedule sets forth (i) the
name of each corporation, partnership, limited liability company or other entity
in which the Company holds a direct or indirect equity, profit, voting or other
interest, (ii) a description of the interests of the Company and (iii) the name

     SECTION 3.7  SEC Documents.  Except as set forth in Schedule 3.7, the
Company has filed all required registration statements, reports, proxy
statements, information statements, forms and other documents with the
Securities and Exchange Commission ("SEC") since December 31, 1996
(collectively, including any such reports filed subsequent to the date hereof
and as amended, the "Company SEC Documents"). As of their respective dates (or,
if amended, as of the date of such amendment), (i) the Company SEC Documents

Act or the Exchange Act, as the case may be, applicable to such Company SEC
Documents, and (ii) none of the Company SEC Documents contained, and no Company
SEC Documents filed subsequent to the date hereof will contain, any untrue
statement of a material fact or omitted to state any material fact required to
be stated therein or necessary in order to make the statements made therein, in
light of the circumstances under which they were made, not misleading.

undisclosed liabilities which are reasonably likely, individually or in the

consolidated balance sheet included in the Company SEC Documents filed and
publicly available prior to the date of this Agreement.

     SECTION 3.9  Disclosure Documents.  Each document required to be filed by

law, including without limitation, the Exchange Act. The Company Disclosure
Documents will not at the time of the filing thereof or at the time of

in the Company Disclosure Documents based upon information furnished to the
Company in writing by Buyer or Merger Subsidiary specifically for use therein.

          (v) The most recent determination letter from the Puerto Rico
     Department of the Treasury with respect to each Plan that is intended to be
     qualified under Section 1165(a) of the Puerto Rico Internal Revenue Code of

     (c) No material liability under Title IV of ERISA has been incurred by the
Company or any ERISA Affiliate that has not been satisfied in full, and, to the
knowledge of the Company, no condition exists that presents a material risk to
the Company or an ERISA Affiliate of incurring a liability under such Title,
other than liability for premiums due the Pension Benefit Guaranty Corporation
("PBGC"), which payments have been made when due.

     (d) Neither the Company nor any ERISA Affiliate, has engaged in a
transaction or has taken or failed to take any action in connection with which
the Company could reasonably be expected to be subject to either a material
civil penalty assessed pursuant to Section 409 or 502(i) of ERISA or a material
Tax imposed pursuant to Section 4975, 4976 or 4980B of the Code.

     (e) Except as set forth in Schedule 3.13(e) of the Company Disclosure

1165(a) of the PRIRC is so qualified and has received a favorable determination
letter from the Internal Revenue Service with respect to "TRA" (as defined in
Section 1 of Rev. Proc. 93-39), and the Company is not aware of any
circumstances likely to result in revocation of any such favorable determination
letter. There is no material pending or, to the knowledge of the Company,
threatened litigation relating to the Plans.

     (f) No liability under Subtitle C or D of Title IV of ERISA has been or is
expected to be incurred by the Company or any of its subsidiaries with respect

required to be filed in connection with the transactions contemplated by this
Agreement.

     (g) All contributions required to be made under the terms of any Benefit
Plan have been timely made or have been reflected on the Audited Financial

any single-employer plan of an ERISA Affiliate has an "accumulated funding
deficiency" (whether or not waived) within the meaning of Section 412 of the
Code or Section 302 of ERISA and no ERISA Affiliate has an outstanding funding
waiver. Neither the Company nor any of its subsidiaries has provided, or is
required to provide, security to any Pension Plan or to any single-employer plan
of an ERISA Affiliate pursuant to Section 401(a)(29) of the Code.

     (h) Under each Pension Plan which is a single-employer plan, as of the last
day of the most recent plan year ended prior to the date hereof, the actuarially
determined present value of all "benefit liabilities", within

                                      A-14
<PAGE>   62

the meaning of Section 4001(a)(16) of ERISA (as determined on the basis of the
actuarial assumptions contained in the Plan's most recent actuarial valuation),
did not exceed the then current value of the assets of such Plan, and there has
been no material change in the financial condition of such Plan since the last
day of the most recent plan year.

     (i) Neither the Company nor any of its subsidiaries has any obligations for
retiree health and life benefits under any Plan, except as set forth on Schedule
3.13(i) of the Company Disclosure Schedule. The Company or the subsidiaries may
amend or terminate any such Plan at any time without incurring any liability
thereunder.

benefits under, increase the amount payable or trigger any other material
obligation pursuant to, any of the Plans or (z) result in any breach or
violation of, or a default under, any of the Plans.

Laws and no property that has been owned or operated by the Company or any
Subsidiary has any contamination requiring investigation or remediation under
any Environmental Law.

     (c) (i) The Company has made available to Buyer any material environmental

Company, the Shares, the Merger or the other transactions contemplated by this

businesses of the Company and its Subsidiaries and owned by the Company or its
Subsidiaries (the "System") are designed to operate during and after the
calendar year 2000 to accurately process data (including but not limited to
calculating, comparing, and sequencing) from, into and between the twentieth and
twenty-first centuries, including leap year calculations ("Year 2000
Compliant"), and the Company is using its reasonable best efforts to implement
the Year 2000 Plan with respect to the Systems in accordance with the terms
thereof. The Company has delivered to Buyer a true and complete copy of the Year
2000 Plan.

vendors and suppliers are taking reasonable steps to confirm that their systems
and software are Year 2000 Compliant and that as of the date hereof no material
problems have been reported to the Company or its Subsidiaries.

     or (ii) where such transaction, commitment, contract, agreement,

     than $5 million of payments or receipts in total, or pursuant to which the
     Company or any of its Subsidiaries incurs obligations extending, either by
     the initial term thereof or by renewal, beyond January 1, 2001; provided,

     making the calculations contemplated by this clause 5.1(v)) or (ii) enter
     into any transactions with affiliates of the Company with an aggregate

     SECTION 5.2  Stockholder Meeting; Proxy Material.  The Company shall cause
a meeting of its stockholders (the "Company Stockholder Meeting") to be duly
called as soon as reasonably practicable after the date hereof and held as soon
as reasonably practicable for the purpose of voting on the adoption of this
Agreement. The Board of Directors of the Company shall recommend adoption of
this Agreement by the Company's stockholders; provided that the Company's Board
of Directors may withdraw, modify or change such recommendation if it has
determined, after consultation with outside legal counsel to the Company, that
such recommendation would violate the Board of Directors' fiduciary duties under
applicable law. Notwithstanding anything to the contrary contained in this
Agreement, the Company shall hold the Company Stockholders Meeting for the
purpose of allowing the Company's stockholders to vote on the adoption of this
Agreement (including in the event that the Board of Directors of the Company has
determined at any time subsequent to the date hereof that this Agreement is no
longer advisable and recommends that the shareholders of the Company reject it).
In connection with the Company Stockholder Meeting, the Company (i) will
promptly prepare and file with the SEC, will use its reasonable best efforts to
have cleared by the SEC and will thereafter or if the SEC has indicated that it
will not provide comments, on the tenth day after the filing mail to its
stockholders as promptly as practicable a proxy statement and all other proxy
materials for such meeting (the "Company Proxy Statement"), (ii) will use its
best efforts to obtain the necessary approvals by its stockholders of this
Agreement and the transactions contemplated hereby and (iii) will otherwise
comply with all legal requirements applicable to such meeting.

     SECTION 5.3  Access to Information; Confidentiality Agreement.  From the
date hereof until the Effective Time, the Company will give Buyer, its counsel,
financial advisors, auditors and other authorized representatives reasonable
access during normal business hours to the offices, properties, books and
records of the Company and the Subsidiaries of the Company, will furnish to
Buyer, its counsel, financial advisors, auditors and other authorized
representatives such financial and operating data and other information as such
Persons may reasonably request and will instruct the Company's employees,
counsel, accountants and financial advisors to cooperate with Buyer in its
investigation of the business of the Company and the Subsidiaries of the
Company; provided that all requests for information, to visit plants or
facilities or to interview the Company's employees or agents should be directed
to and coordinated with Stephen Shapiro or Richard Lubasch or, in their absence,
another person designated by the Company, and the Company will cause Messrs.
Lubasch and Shapiro and any such other person designated to cooperate with Buyer
or its representatives in scheduling such visits or interviews; and provided
further that no investigation pursuant to this Section 5.3 shall affect any
representation or warranty given by the Company to Buyer hereunder and any
information received by Buyer or its representatives shall remain subject to the
Confidentiality Agreement dated January 21, 1999 between Buyer and the Company
(the "Confidentiality Agreement").

     SECTION 5.4  No Solicitation.  The Company and its Subsidiaries and their
respective officers and directors will not, and the Company will use its best
efforts to ensure that the respective officers, directors, employees or other
agents (including any investment banker, attorney, consultant or accountant
retained by it or its Subsidiaries) of the Company and its Subsidiaries will
not, directly or indirectly, solicit, initiate, encourage or otherwise
facilitate any Acquisition Proposal (as defined below). The Company further
agrees that it and its Subsidiaries, officers and directors will not, and the
officers and directors of its Subsidiaries will

                                      A-21
<PAGE>   69

not, and the Company will use its best efforts to ensure that the respective
officers, directors and employees or other agents (including any investment
banker, attorney, consultant or accountant retained by it or its Subsidiaries)
of the Company and its Subsidiaries will not, directly or indirectly, engage in
substantive discussions or negotiations with, disclose any nonpublic information
relating to the Company or any Subsidiary of the Company or afford access to the
properties, books or records of the Company or any Subsidiary of the Company or
have any discussion with, any Person relating to an Acquisition Proposal;
provided that, if prior to the date of the Company Stockholders Meeting (x) such
Person 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 from a
financial point of view to the Company and its stockholders than the Merger
Consideration and the Board of Directors of the Company determines in good faith
(after consultation with a nationally recognized investment banking firm) that
such Acquisition Proposal, if accepted, is reasonably likely to be consummated,
taking into account all legal, financial and regulatory aspects of the proposal
and the financial capacity and any other relevant characteristics of the Person
making the Acquisition Proposal and which is not conditioned upon obtaining
financing (any such proposal meeting such criteria being a "Superior Proposal"),
and (y) the Company's Board of Directors determines, after consultation with
outside legal counsel to the Company, that engaging in such negotiations or
substantive discussions or providing such information is necessary for the Board
of Directors' to comply with its fiduciary duties under applicable law, the
Company may in response to such Acquisition Proposal furnish information with
respect to the Company and its Subsidiaries pursuant to a confidentiality
agreement no less onerous to the Person making the Acquisition Proposal than the
Confidentiality Agreement and participate in negotiations and, subject to the
terms of their Agreement, enter into agreements regarding such Acquisition
Proposal. The Company will notify Buyer as promptly as practicable if any such
inquiries, proposals or offers are received by, any such information is
requested from, or any such discussions or negotiations are sought to be
initiated or continued with any representative of the Company indicating the
name of the Person contacting the Company and any material terms of any such
proposals or offers and will keep Buyer informed on a reasonably current basis
of the status and details of any such Acquisition Proposal, indication or
request. For purposes of this Agreement, "Acquisition Proposal" means any offer
or proposal for a merger or other business combination involving the Company or
any Subsidiary of the Company or the acquisition of any equity interest in, or a
substantial portion of the assets of, the Company or any Subsidiary of the
Company, other than the transactions contemplated by this Agreement (an
"Acquisition"). Furthermore, nothing contained in this Section 5.4 shall
prohibit the Company or its Board of Directors from 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(a) promulgated under the
Exchange Act or making such disclosure that the Board of Directors concludes in
good faith after consultation with outside counsel is required by applicable
Delaware law, taking into account any disclosures made pursuant to Rules 14d-9
and 14e-2(a).

     SECTION 5.5  Conveyance Taxes.  The Company shall timely pay any real
property transfer or gains, sales, use, transfer, value added, stock transfer
and stamp taxes, any transfer, recording, registration and other fees, and any
similar taxes (collectively, the "Conveyance Taxes") which become payable prior
to the Effective Time in connection with the transactions contemplated hereunder
that are required to be paid in connection therewith.

     SECTION 5.6  Takeover Statutes.  If any Takeover Statute is or may become
applicable to the Merger or the other transactions contemplated by this
Agreement, the Company and its Board of Directors shall grant such approvals and
take such actions as are necessary so that such transactions may be consummated
as promptly as practicable on the terms contemplated by this Agreement or by the
Merger and otherwise act to eliminate or minimize the effects of such statute or
regulation on such transactions.

                                   ARTICLE VI

                               COVENANTS OF BUYER

     Buyer agrees that:

     SECTION 6.1  Obligations of Merger Subsidiary.  Buyer will take all action
necessary to cause Merger Subsidiary to perform its obligations under this
Agreement and to consummate the Merger on the terms and conditions set forth in
this Agreement.

     SECTION 6.2  Director and Officer Liability.  (a) For a period of six years
after the Effective Time, Buyer will, and will cause the Surviving Corporation
to, (i) indemnify and hold harmless the individuals who on or prior to the
Effective Time were officers, directors or employees of the Company (when acting
in such capacity) and any of its Subsidiaries (the "Indemnitees") against all
losses, reasonable expenses, claims, damages or liabilities incurred in
connection with any claim, action, suit or proceeding arising out of acts or
omissions occurring at or prior to the Effective Time (including, without
limitation, in respect of acts or omissions in connection with this Agreement
and the transactions contemplated hereby) to the full extent permitted or
required under applicable law and (ii) advance to such Indemnitees expenses
(including attorneys' fees) incurred in defending any action or suit with
respect to such matters (including the cost of any investigation and preparation
incurred in connection thereof), in each case to the fullest extent such
Indemnitees are entitled to advancement of expenses under and subject to the
terms of the Company Certificate of Incorporation, Company By-laws or the
certificate of incorporation or by-laws of any Subsidiary of the Company (if the
Indemnitee was acting in such Indemnitee's capacity as an officer, director or
employee); provided that in each case the Indemnitee to whom expenses are
advanced provides an undertaking to repay such advances if it is ultimately
determined that such Indemnitee is not entitled to indemnification. To the
extent permitted by the DGCL, such advancement of expenses pursuant to this
Section 6.3 shall be mandatory rather than permissive. In the event any claim or
claims are asserted or made within such six year period, all rights to
indemnification in respect of any such claim or claims shall continue until
disposition of any and all such claims. Any determination required to be made
with respect to whether any of the Indemnitees are entitled to indemnification
as set forth in this Section 6.3 shall be made by independent legal counsel
selected mutually by such Indemnitee and Buyer.

     (b) Any Indemnitee wishing to claim indemnification under paragraph (a) of
this Section 6.2, upon learning of any such claim, action, suit or shall
promptly notify Buyer thereof, but the failure to so notify shall not relieve
the Surviving Corporation of any liability it may have to indemnitee if such
failure does not materially prejudice Buyer or the Surviving Corporation;
provided that if the failure to so notify Buyer materially prejudices Buyer or
the Surviving Corporation, Buyer or the Surviving Corporation, as the case may
be, will be relieved of liability it would otherwise have had pursuant to this
Agreement to the extent of such material prejudice. In the event of any such
claim, action, suit or proceeding, (i) Buyer or the Surviving Corporation shall
have the right to assume the defense thereof and Buyer shall not be liable to
such Indemnitee for any legal expenses of other counsel or any other expenses
subsequently incurred by such indemnitee in connection with the defense thereof,
(ii) the Indemnitee will cooperate in the defense of any such matter and (iii)
Buyer shall not be liable for any settlement effected without its prior written
consent; and provided further that Buyer shall not have any obligation hereunder
to any Indemnitee if and when a court of competent jurisdiction shall ultimately
determine, and such determination shall have become final, that the
indemnification of such Indemnitee in the manner contemplated is prohibited by
applicable law.

     (c) Buyer, Merger Subsidiary and the Company agree that all rights to
indemnification and all limitations on liability existing in favor of any such
Indemnitee as provided in the Company Certificate of Incorporation, Company
By-laws or an agreement between an Indemnitee and the Company or a Subsidiary of
the Company as in effect as of the date hereof shall survive the Merger and
continue in full force and effect. For a period of six years after the Effective
Time, Buyer will, and will cause the Surviving Corporation to, provide officers'
and directors' liability insurance in respect of acts or omissions occurring
prior to the Effective Time covering each such Person currently covered by the
Company's officers' and directors' liability insurance policy ("D&O Insurance")
on terms with respect to coverage and amount no less favorable than those of
such policy in effect on the date hereof so long as the annual premium therefor
does not exceed 150% of the annual
                                      A-23
<PAGE>   71

premium payable pursuant to the renewal policy disclosed to Buyer (the "Current
Premiums"); provided, however, that if the existing D&O Insurance expires, is
terminated or canceled during such six-year period, the Surviving Corporation
will use its reasonable best efforts to obtain as much D&O Insurance as can be
obtained for the remainder of such period for a premium not in excess (on an
annualized basis) of 150% of the Current Premium. Buyer agrees that, should the
Surviving Corporation fail to comply with the obligations of this Section 6.3,
Buyer shall be responsible therefor to the extent permitted by Delaware law.

     (d) In the event the Company or the Surviving Corporation or any of their
respective successors or assigns (i) consolidates with or merges into any other
person or entity or (ii) transfers all or substantially all of its properties or
assets to any Person, then, and in each case, proper provision shall be made so
that successors and assigns of the Company or the Surviving Corporation, as the
case may be, honor the indemnification obligations set forth in this Section
6.3.

     (e) The obligations of the Company, the Surviving Corporation, and Buyer
under this Section 6.3 shall not be terminated or modified in such a manner as
to adversely affect in any Indemnitee to whom this Section 6.3 applies without
the consent of such affected Indemnitee (it being expressly agreed that the
Indemnitees to whom this Section 6.3 applies shall be third party beneficiaries
of this Section 6.3.

                                  ARTICLE VII

     The parties hereto agree that:

     SECTION 7.1  Reasonable Efforts.  Subject to the terms and conditions of

cause to be filed, and share equally the fee for, the notification and report
forms required under the HSR Act and make promptly any required submissions
under the HSR Act with respect to the transactions contemplated by this
Agreement, (ii) to the extent required by applicable laws, file with the FCC
applications for consent to transfer of control of the Licenses, as applicable,
and such other applications as may be advisable in the reasonable judgment of
the parties hereto, which applications will comply in all material respects with
the requirements of the Communication Act of 1934, as amended, and (iii) file
applications for all consents and approvals of State Governmental Bodies and
other regulatory consents and approvals necessary for the consummation of the
transactions contemplated by this Agreement, and (b) to cooperate with one
another (i) in promptly determining whether any filings are reasonably required
to be or should be made or consents, approvals, permits or authorizations are
required to be or should be obtained under any other federal, state or local law
or regulation and (ii) in promptly making any such filings, furnishing
information required in connection therewith and using commercially reasonable
efforts to seek to obtain timely any such consents, permits, authorizations,
approvals or waivers.

     SECTION 7.3  Public Announcements.  Buyer and the Company will consult with
each other before issuing any press release or making any public statement with
respect to this Agreement and the transactions contemplated hereby and, except
(i) as may be required by applicable law or any listing agreement with any
national securities exchange or foreign securities exchange or (ii) for any
communication by the Company to its employees describing the terms of this
Agreement, will not issue any such press release or make any such public
statement prior to such consultation. To the extent that anything in this
Section 7.3 conflicts with the terms of the Confidentiality Agreement, this
Section 7.3 shall prevail.

     SECTION 7.4  Conveyance Taxes.  Buyer and the Company shall cooperate in
the preparation, execution and filing of all Tax Returns, questionnaires,
applications, or other documents regarding any

                                      A-24
<PAGE>   72

Conveyance Taxes which become payable in connection with the transactions
contemplated hereunder that are required or permitted to be filed on or before
the Effective Time.

     SECTION 7.5  Further Assurances.  At and after the Effective Time, the
officers and directors of the Surviving Corporation will be authorized to
execute and deliver, in the name and on behalf of the Company or Merger
Subsidiary, any deeds, bills of sale, assignments or assurances and to take and
do, in the name and on behalf of the Company or Merger Subsidiary, any other
actions and things to vest, perfect or confirm of record or otherwise in the
Surviving Corporation any and all right, title and interest in, to and under any
of the rights, properties or assets of the Company acquired or to be acquired by
the Surviving Corporation as a result of, or in connection with, the Merger.

     SECTION 7.6  Employee Matters.  (a) For a period of one year immediately
following the Closing Time, Buyer agrees to cause the Surviving Corporation and
its Subsidiaries to provide to all active employees of the Company who continue
to be employed by the Company as of the Effective Time ("Continuing Employees")
coverage by benefit plans or arrangements which are, in the aggregate, no less
favorable in the aggregate than those provided to the employees immediately
prior to the Closing Time with the exception of any stock option, stock purchase
or other stock compensation plan.

     (b) For a period of one year immediately following the Closing Time, Buyer
agrees to cause the Surviving Corporation and its Subsidiaries to provide to all
active employees of the Company at the Closing Time which may be affected by any
reduction in force subsequent to the Closing Time benefits no less favorable in
the aggregate than the benefits set forth in the Severance Policy adopted by the
Board of Directors of the Company and included as Schedule 7.6 of the Company
Disclosure Schedule.

     (c) Promptly after the execution of this Agreement, the Company shall mail
to each person who is a holder of Option granted pursuant to any of the Stock
Option Plans (regardless of whether such Options are vested or exercisable at
the time) a letter in a form acceptable to Buyer which describes the treatment
of and payment for such Options pursuant to Schedule 3.5 of the Company
Disclosure Schedule and provides instructions for use in obtaining payment for
such Options pursuant to Schedule 3.5 of the Company Disclosure Schedule. Each
such holder shall be requested to sign a release by which the holder effectively
relinquishes all rights with respect to all Options issued pursuant to any of
the Stock Option Plans upon payment therefor in accordance with Schedule 3.5 of
the Company Disclosure Schedule in connection with the Closing.

                                  ARTICLE VIII

     restrains, enjoins or otherwise prohibits consummation of the Merger
     (collectively, an "Order"), and no Governmental Entity or any other Person
     shall have instituted any proceeding seeking such an Order; and

          (d) Other than the Certificate of Merger, all notices, reports and

                                      A-25
<PAGE>   73

     consents, registrations, approvals, permits and authorizations required to
     be obtained prior to the Effective Time by the Company or Buyer from any
     Governmental Entity (collectively, "Governmental Consents") in connection
     with the execution and delivery of this Agreement and the consummation of
     the Merger shall have been made or obtained upon terms and conditions that
     are not reasonably likely to have a Material Adverse Effect on Buyer or the

     a Material Adverse Effect on the Company or Buyer.

     SECTION 8.2  Conditions to the Obligations of Buyer and Merger
Subsidiary.  The obligations of the Buyer and Merger Subsidiary to effect the
Merger shall be subject to the fulfillment or waiver at the Closing Time of the

     Adverse Effect shall be true and correct, except that, other than with
     respect to the representations and warranties set forth on Schedule 8.2(b)
     which shall be true and correct, this clause (ii) shall be deemed satisfied

     and as of the Closing Time as if made on and as of such dates (except to
     the extent that any such representation or warranty had by its terms been

     the transactions contemplated by this Agreement under each Material

of the Company to effect the Merger shall be subject to the fulfillment or
waiver at the Closing Time of the following additional conditions:

                                  TERMINATION

     SECTION 9.1  Termination by Mutual Consent.  This Agreement may be
terminated and the Merger may be abandoned at any time prior to the Effective
Time, whether before or after the approval by stockholders of the Company
referred to in Section 5.2 hereof, by mutual written consent of the Company and
Buyer by action of their respective Boards of Directors.

     SECTION 9.2  Termination by Either Buyer or the Company.  This Agreement
may be terminated and the Merger may be abandoned at any time prior to the
Effective Time by action of the Board of Directors of either Buyer or the
Company if (i) the Merger shall not have been consummated by February 1, 2000,
whether such date is before or after the date of approval by the stockholders of
the Company; provided, however, that if either party determines that additional
time is necessary in order to forestall any action to restrain, enjoin or
prohibit the Merger by any Governmental Entity, the Termination may be extended
by such party to a date not beyond May 1, 2000 (the "Termination Date"), (ii)
the approval of the Company's stockholders required by Section 5.2 hereof shall
not have been obtained at a meeting duly convened therefor or at any adjournment
or postponement thereof or (iii) any Order permanently restraining, enjoining or
otherwise prohibiting consummation of the Merger shall be a Final Order;
provided, that the right to terminate this Agreement pursuant to clause (i)
above shall not be available to any party that has breached in any material
respect its obligations under this Agreement in any manner that shall have
proximately contributed to the occurrence of the failure of the Merger to be
consummated.

     SECTION 9.3  Termination by the Company.  This Agreement may be terminated
and the Merger may be abandoned at any time prior to the approval by
stockholders of the Company referred to in Section 5.2 hereof, by action of the
Board of Directors of the Company:

          (a) if (i) the Company is not in material breach of any of the terms
     of this Agreement, (ii) the Board of Directors of the Company authorizes
     the Company, subject to complying with the terms of this Agreement, to
     enter into a binding written agreement concerning a transaction that
     constitutes a Superior Proposal and the Company notifies Buyer in writing
     that it intends to enter into such an agreement, attaching the most current
     version of such agreement to such notice, (iii) Buyer does not make, within
     five Business Days after receipt of the Company's written notification of
     its intention to enter into a binding agreement for a Superior Proposal, an
     offer that the Board of Directors of the Company determines, in good faith
     after consultation with an investment banker of national reputation, is at
     least as favorable, from a financial point of view, to the stockholders of
     the Company as the Superior Proposal and (iv) the Company prior to such
     termination pays to Buyer in immediately available funds any fees required
     to be paid pursuant to Section 9.5. The Company agrees (x) that it will not
     enter into a binding agreement referred to in clause (iii) above until at
     least the sixth Business Day after it has provided the notice to Buyer
     required thereby and (y) to notify Buyer promptly if its intention to enter
     into a written agreement referred to in its notification shall change at
     any time after giving such notification.

          (b) if there has been a material breach by Buyer or Merger Subsidiary
     of any representation, warranty, covenant or agreement contained in this
     Agreement that is not curable or, if curable, is not cured within 30 days
     after written notice of such breach is given by the Company to the party
     committing such breach.

     SECTION 9.4  Termination by Buyer.  This Agreement may be terminated and
the Merger may be abandoned at any time prior to the Effective Time by action of
the Board of Directors of Buyer if: (i) the Board of Directors of the Company
shall have withdrawn or adversely modified its approval or recommendation of
this Agreement, (ii) there has been a material breach by the Company of any
representation, warranty, covenant or agreement contained in this Agreement that
is not curable or, if curable, is not cured within 30 days after written notice
of such breach is given by Buyer to the party committing such breach or (iii) if
the Company or any of the other Persons described in Section 5.4 shall (a)
wilfully and materially breach Section 5.4 or (b) take any of the actions that
would be proscribed by Section 5.4 but for the proviso therein allowing certain
actions to be taken pursuant to the proviso under the conditions set forth
therein.

     SECTION 9.5  Effect of Termination and Abandonment.  (a) In the event of
termination of this Agreement and the abandonment of the Merger pursuant to this
Article IX, this Agreement (other than as set forth in Section 11.2 (Survival))
shall become void and of no effect with no liability on the part of any party
hereto (or of any of its directors, officers, employees, agents, legal and
financial advisors or other representatives); provided, however, no such
termination shall relieve any party hereto of any liability or damages resulting
from any breach of this Agreement.

     (b) In the event that (i) an Acquisition Proposal shall have been made to
the Company or any of its Subsidiaries or any of its stockholders or any Person
shall have publicly announced an intention (whether or not conditional) to make
an Acquisition Proposal with respect to the Company or any of its Subsidiaries
and thereafter this Agreement is terminated by either Buyer or the Company
pursuant to Section 9.2(ii) or (ii) this Agreement is terminated (x) by the
Company pursuant to Section 9.3(a) or (y) by Buyer pursuant to Section 9.4(i) or
9.4(iii)(a), then the Company shall promptly, but in no event later than two
days after the date of such termination (or in the case of termination pursuant
to Section 9.3(a) immediately prior to the termination thereof by the Company),
pay Buyer a termination fee of $20 million (the "Termination Fee"). In the event
that this Agreement is terminated pursuant to Section 9.4(iii)(b) and either (x)
within six months thereafter the Company enters into an agreement providing for
an Acquisition or (y) within two years thereafter the Company enters into an
agreement providing for an Acquisition with a Person with whom the Company had
substantive discussions or negotiated or to whom the Company disclosed, or
afforded access, to any nonpublic information prior to the termination of this
Agreement pursuant to the proviso in Section 5.4, then the Company shall pay
Buyer the Termination Fee within two Business Days after the entry into such
agreement. The Company acknowledges that the agreements contained in this
Section 9.5(b) are an integral part of the transactions contemplated by this
Agreement, and that, without these agreements, Buyer and Merger Sub would not
enter into this Agreement; accordingly, if the Buyer shall commence an action to
obtain payment of such fee, the prevailing party in such action shall be
reimbursed for its reasonable costs and expenses (including reasonable
attorney's fees) in prosecuting or defending such action. If the Buyer shall
prevail in such action, the Company shall pay interest on the Termination Fee
(at the prime rate of Citibank N.A. in effect on the date such payment was
required to be made) from the date such payment was required to be made to the
date made.

                                                                  April 30, 1999

Board of Directors
Cellular Communications of Puerto Rico, Inc.
110 East 59th Street
26th Floor
New York, NY 10022

Gentlemen:

     You have requested our opinion as to the fairness from a financial point of
view to the holders of the outstanding shares of Common Stock, par value $0.01
per share (the "Common Stock") of Cellular Communications of Puerto Rico, Inc.
(the "Company") of the consideration to be received by such holders pursuant to
the terms of the Agreement and Plan of Merger, dated as of April 30, 1999 (the
"Agreement"), by and among the Company, SBC Communications Inc. ("SBC"), and
SBCI-PR, Inc., a wholly owned subsidiary of SBC ("Merger Sub"), pursuant to
which Merger Sub will be merged (the "Merger") with and into the Company.

     Pursuant to the Agreement, each share of Company Common Stock will be
converted, subject to certain exceptions, into the right to receive $29.50 per
share in cash.

     In arriving at our opinion, we have reviewed the Agreement and the
schedules thereto. We also have reviewed financial and other information that
was publicly available or furnished to us by the Company including information
provided during discussions with management. Included in the information
provided to us during discussions with management were certain financial
projections of the Company for the period beginning January 1, 1999 and ending
December 31, 2003, that were prepared by the management of the Company (the
"Company Projections"). In addition, we have compared certain financial and
securities data of the Company with certain other companies whose securities are
traded in public markets, reviewed the historical stock prices and trading
volumes of Company Common Stock, reviewed prices and premiums paid in certain
other business combinations and conducted such other financial studies, analyses
and investigations as we deemed appropriate for purposes of this opinion.

     In rendering our opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all of the financial
and other information that was available to us from public sources, that was
provided to us by the Company or its representatives, or that was otherwise
reviewed by us. With respect to the Company Projections, we have assumed that
they have been reasonably prepared on a basis reflecting the best currently
available estimates and judgments of the management of the Company as to the
future operating and financial performance of the Company. We have not assumed

conditions as they exist on, and on the information made available to us as of,
the date of this letter. It should be understood that, although subsequent
developments may affect this opinion, we do not have any obligation to update,

merits of the Merger and the other business strategies being considered by the
Company's Board of Directors, nor does it address the Board's decision to

of the opinion that the consideration to be received by the holders of Company
Common Stock pursuant to the Agreement is fair to such holders from a financial
point of view.

                        DELAWARE GENERAL CORPORATION LAW

SEC. 262 APPRAISAL RIGHTS

     (a) Any stockholder of a corporation of this State who holds shares of
stock on the date of the making of a demand pursuant to subsection (d) of this
section with respect to such shares, who continuously holds such shares through
the effective date of the merger or consolidation, who has otherwise complied
with subsection (d) of this section and who has neither voted in favor of the
merger or consolidation nor consented thereto in writing pursuant to sec. 228 of
this title shall be entitled to an appraisal by the Court of Chancery of the
fair value of the stockholder's shares of stock under the circumstances
described in subsections (b) and (c) of this section. As used in this section,
the word "stockholder" means a holder of record of stock in a stock corporation
and also a member of record of a nonstock corporation; the words "stock" and
"share" mean and include what is ordinarily meant by those words and also
membership or membership interest of a member of a nonstock corporation; and the
words "depository receipt" mean a receipt or other instrument issued by a
depository representing an interest in one or more shares, or fractions thereof,
solely of stock of a corporation, which stock is deposited with the depository.

     (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to sec. 251 (other than a merger effected pursuant to sec. 251
(g) of this title), sec. 252, sec. 254, sec. 257, sec. 258, sec. 263 or sec. 264
of this title:

          (1) Provided, however, that no appraisal rights under this section
     shall be available for the shares of any class or series of stock, which
     stock, or depository receipts in respect thereof, at the record date fixed
     to determine the stockholders entitled to receive notice of and to vote at
     the meeting of stockholders to act upon the agreement of merger or
     consolidation, were either (i) listed on a national securities exchange or
     designated as a national market system security on an interdealer quotation
     system by the National Association of Securities Dealers, Inc. or (ii) held
     of record by more than 2,000 holders; and further provided that no
     appraisal rights shall be available for any shares of stock of the
     constituent corporation surviving a merger if the merger did not require
     for its approval the vote of the stockholders of the surviving corporation
     as provided in subsection (f) of sec. 251 of this title.

          (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
     under this section shall be available for the shares of any class or series
     of stock of a constituent corporation if the holders thereof are required
     by the terms of an agreement of merger or consolidation pursuant to
     sec.sec. 251, 252, 254, 257, 258, 263 and 264 of this title to accept for
     such stock anything except:

             a.  Shares of stock of the corporation surviving or resulting from
        such merger or consolidation, or depository receipts in respect thereof,

             b.  Shares of stock of any other corporation, or depository
        receipts in respect thereof, which shares of stock or depository
        receipts at the effective date of the merger or consolidation will be
        either listed on a national securities exchange or designated as a
        national market system security on an interdealer quotation system by
        the National Association of Securities Dealers, Inc. or held of record
        by more than 2,000 holders;

             c.  Cash in lieu of fractional shares or fractional depository
        receipts described in the foregoing subparagraphs a. and b. of this
        paragraph; or

             d.  Any combination of the shares of stock, depository receipts and
        cash in lieu of fractional shares or fractional depository receipts
        described in the foregoing subparagraphs a., b. and c. of this
        paragraph.

          (3) In the event all of the stock of a subsidiary Delaware corporation
     party to a merger effected under sec. 253 of this title is not owned by the
     parent corporation immediately prior to the merger, appraisal rights shall
     be available for the shares of the subsidiary Delaware corporation.

     (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.

     (d) Appraisal rights shall be perfected as follows:

          (1) If a proposed merger or consolidation for which appraisal rights
     are provided under this section is to be submitted for approval at a
     meeting of stockholders, the corporation, not less than 20 days prior to
     the meeting, shall notify each of its stockholders who was such on the
     record date for such meeting with respect to shares for which appraisal
     rights are available pursuant to subsections (b) or (c) hereof that
     appraisal rights are available for any or all of the shares of the
     constituent corporations, and shall include in such notice a copy of this
     section. Each stockholder electing to demand the appraisal of his shares
     shall deliver to the corporation, before the taking of the vote on the
     merger or consolidation, a written demand for appraisal of his shares. Such
     demand will be sufficient if it reasonably informs the corporation of the
     identity of the stockholder and that the stockholder intends thereby to
     demand the appraisal of his shares. A proxy or vote against the merger or
     consolidation shall not constitute such a demand. A stockholder electing to
     take such action must do so by a separate written demand as herein
     provided. Within 10 days after the effective date of such merger or
     consolidation, the surviving or resulting corporation shall notify each
     stockholder of each constituent corporation who has complied with this
     subsection and has not voted in favor of or consented to the merger or
     consolidation of the date that the merger or consolidation has become
     effective; or

          (2) If the merger or consolidation was approved pursuant to sec. 228
     or sec. 253 of this title, each constituent corporation, either before the
     effective date of the merger or consolidation or within ten days
     thereafter, shall notify each of the holders of any class or series of
     stock of such constituent corporation who are entitled to appraisal rights
     of the approval of the merger or consolidation and that appraisal rights
     are available for any or all shares of such class or series of stock of
     such constituent corporation, and shall include in such notice a copy of
     this section; provided that, if the notice is given on or after the
     effective date of the merger or consolidation, such notice shall be given
     by the surviving or resulting corporation to all such holders of any class
     or series of stock of a constituent corporation that are entitled to
     appraisal rights. Such notice may, and, if given on or after the effective
     date of the merger or consolidation, shall, also notify such stockholders
     of the effective date of the merger or consolidation. Any stockholder
     entitled to appraisal rights may, within 20 days after the date of mailing
     of such notice, demand in writing from the surviving or resulting
     corporation the appraisal of such holder's shares. Such demand will be
     sufficient if it reasonably informs the corporation of the identity of the
     stockholder and that the stockholder intends thereby to demand the
     appraisal of such holder's shares. If such notice did not notify
     stockholders of the effective date of the merger or consolidation, either
     (i) each such constituent corporation shall send a second notice before the
     effective date of the merger or consolidation notifying each of the holders
     of any class or series of stock of such constituent corporation that are
     entitled to appraisal rights or the effective date of the merger or
     consolidation or (ii) the surviving or resulting corporation shall send
     such a second notice to all such holders on or within 10 days after such
     effective date; provided, however, that if such second notice is sent more
     than 20 days following the sending of the first notice, such second notice
     need only be sent to each stockholder who is entitled to appraisal rights
     and who has demanded appraisal of such holder's shares in accordance with
     this subsection. An affidavit of the secretary or assistant secretary or of
     the transfer agent of the corporation that is required to give either
     notice that such notice has been given shall, in the absence of fraud, be
     prima facie evidence of the facts stated therein. For purposes of
     determining the stockholders entitled to receive either notice, each
     constituent corporation may fix, in advance, a record date that shall be
     not more than 10 days prior to the date the notice is given, provided, that
     if the notice is given on or after the effective date of the merger or
     consolidation, the record date shall be such effective date. If no record
     date is fixed and the notice is given prior to the effective date, the
     record date shall be the close of business on the day next preceding the
     day on which the notice is given.

                                       C-2

     (e) Within 120 days after the effective date of the merger or
consolidation, the surviving or resulting corporation or any stockholder who has
complied with subsections (a) and (d) hereof and who is otherwise entitled to
appraisal rights, may file a petition in the Court of Chancery demanding a
determination of the value of the stock of all such stockholders.
Notwithstanding the foregoing, at any time within 60 days after the effective
date of the merger or consolidation, any stockholder shall have the right to
withdraw his demand for appraisal and to accept the terms offered upon the
merger or consolidation. Within 120 days after the effective date of the merger
or consolidation, any stockholder who has complied with the requirements of
subsections (a) and (d) hereof, upon written request, shall be entitled to
receive from the corporation surviving the merger or resulting from the
consolidation a statement setting forth the aggregate number of shares not voted
in favor of the merger or consolidation and with respect to which demands for
appraisal have been received and the aggregate number of holders of such shares.
Such written statement shall be mailed to the stockholder within 10 days after
his written request for such a statement is received by the surviving or
resulting corporation or within 10 days after expiration of the period for
delivery of demands for appraisal under subsection (d) hereof, whichever is
later.

     (f) Upon the filing of any such petition by a stockholder, service of a
copy thereof shall be made upon the surviving or resulting corporation, which
shall within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the addresses
therein stated. Such notice shall also be given by I or more publications at
least I week before the day of the hearing, in a newspaper of general
circulation published in the City of Wilmington, Delaware or such publication as
the Court deems advisable. The forms of the notices by mail and by publication
shall be approved by the Court, and the costs thereof shall be borne by the
surviving or resulting corporation.

     (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court may require the stockholders who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.

     (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate of
interest which the surviving or resulting corporation would have had to pay to
borrow money during the pendency of the proceeding. Upon application by the
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceeding, the Court may, in its discretion, permit discovery
or other pretrial proceedings and may proceed to trial upon the appraisal prior
to the final determination of the stockholder entitled to an appraisal. Any
stockholder whose name appears on the list filed by the surviving or resulting
corporation pursuant to subsection (f) of this section and who has submitted his
certificates of stock to the Register in Chancery, if such is required, may
participate fully in all proceedings until it is finally determined that he is
not entitled to appraisal rights under this section.

     (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as the Court
may direct. Payment shall be so made to each such stockholder, in the case of
holders of uncertificated stock forthwith, and the case of holders of shares
represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
                                       C-3
<PAGE>   86

other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.

     (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.

     (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded his appraisal rights as provided in subsection (d)
of this section shall be entitled to vote such stock for any purpose or to
receive payment of dividends or other distributions on the stock (except
dividends or other distributions payable to stockholders of record at a date
which is prior to the effective date of the merger or consolidation); provided,
however, that if no petition for an appraisal shall be filed within the time
provided in subsection (e) of this section, or if such stockholder shall deliver
to the surviving or resulting corporation a written withdrawal of his demand for
an appraisal and an acceptance of the merger or consolidation, either within 60
days after the effective date of the merger or consolidation as provided in
subsection (e) of this section or thereafter with the written approval of the
corporation, then the right of such stockholder to an appraisal shall cease.
Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery
shall be dismissed as to any stockholder without the approval of the Court, and
such approval may be conditioned upon such terms as the Court deems just.

     (l) The shares of the surviving or resulting corporation to which the
shares of such objecting stockholders would have been converted had they
assented to the merger or consolidation shall have the status of authorized and
unissued shares of the surviving or resulting corporation.
